+![Image of html in black text.][2]
+
+我们可在文档中添加一些简单的样式来为 读者、专家 或者 初学者 突出任何元素。为了使不同的文本更容易区分,让我们把读者类的背景颜色设置成米白色,专家类的字体颜色设置为深红色,初学者的字体颜色则设置为深蓝色。

+
+当你在浏览器中查看这个网页时,这些样式有助于突出这两个段落。安装指导的所有段落都有一个米白色背景,因为他们都有 读者 这个类。第一个段落的字体是深红色的,这是由 专家 这个类定义的。第二个段落的字体是深蓝色的,则是由 初学者 这个类定义的。
+
+![Image of html in red and black text.][3]
+
+### 添加 JavaScript 控件
+
+这些类的应用,使你可以添加一些简单的 JavaScript 函数,只显示其中一个内容块。一个方法是,首先给所有的读者类元素设置 `display:none` 。这会将内容隐藏,使其不会在页面上显示。然后,用函数将你想显示的类元素设置为 `display:block` :
+
+```
+
+```
+
+要在 HTML 文档中使用这个 JavaScript,你可以吧这个功能附加到一个按钮上。由于 `readerview` 函数需要一个听众(这应该是相对那个虚拟音乐播放器来说的)作为参数,你可以使用你想查看的听众类别来调用这个函数,可以是读者,专家 或者 初学者 。

+
+### 将此扩展到你的文档
+
+如果你的项目需要你为不同的听众编写多个操作文档,你可以考虑使用这种方法,一次发布,多次阅读。为所有的用户编写一个文档,是每个人都能很容易的发现和分享你项目的文档。而你也不必同时维护尽在细节上有所不同的多个文档。

+Pulsar:一个由社区主导的以继承 Atom 的开源代码编辑器
+======
+
+> Pulsar 的目标是成为 Atom 的替代品,随着其开发的进一步深入,将挑战 Visual Studio Code。
+
+![Pulsar:一个由社区领导的开源代码编辑器,以延续 Atom 遗志][1]
+
+微软决定杀死 Atom 文本编辑器,以支持 Visual Studio Code,这并不奇怪。
+
+如果你不知道,你可以看一下我们以前的报道:
+
+> [为了支持微软 VS Code,微软的 GitHub 正在扼杀 GitHub 的 Atom 编辑器][5]
+
+虽然你可能有了更好的选择,但曾经流行的 Atom 是一个令人印象深刻的工具。
+
+**它有一个可用的社区构建版**;然而,还有一个新的版本(**Pulsar**),旨在实现与原始 Atom 对等的功能,并引入现代功能和更新架构。
+
+根据它的文档,原来开发 Atom 社区版的团队现在参与创建了 Pulsar。他们之所以做一个独立的复刻版本,是因为项目的目标不同。
+
+**Pulsar** 希望将一切现代化,以成为 Atom 的继承者。
+
+> 💡 Pulsar 是一个新项目,作为 Atom 的新复刻,有开发/测试版本可供测试。
+
+### Pulsar 编辑器看起来怎么样?
+
+![Pulsar 编辑器][2]
+
+当然,用户界面也是大同小异。考虑到 Pulsar 还没有一个稳定的版本,看起来有时会显得有些混淆。
+
+然而,文档、软件包以及从 Git 仓库安装软件包的能力等基本要素看起来都已具备。
+
+根据官方网站的介绍,Pulsar 的主要功能亮点包括:
+
+- 跨平台支持(Linux、macOS 和 Windows)
+- 内置的软件包管理器
+- 智能自动补全
+- 文件系统浏览器
+- 多窗格的用户界面
+- 查找和替换功能
+
+在写这篇文章时,Pulsar 还不能自动更新。你可以通过官方网站安装较新的版本。
+
+![Pulsar 编辑器设置][3]
+
+你可以自定义编辑器、改变键盘绑定、管理软件包、应用主题,并通过所有可用选项配置你的体验。
+
+到目前为止,要说 Pulsar 是否会比 Atom 社区版更好还为时过早。然而,这是我们可以关注的事情。
+
+### 下载并试用 Pulsar
+
+如前所述,Pulsar 正处于早期开发阶段。因此,你可以找到用于 Linux 发行版的二进制文件和 AppImage 文件,你可以在任何发行版上试用。
+
+在我的测试中,它 **在 Linux Mint 不能正常运行**,但在 **Ubuntu 22.04 LTS** 上工作良好。
+
+你可以到它的 [官方下载页面][4] 去获取你的系统所需的软件包,并进行测试。

+Xfce 4.18 版本发布:令人印象深刻
+======
+
+> Xfce 4.18 已发布,添加了一些有趣的功能和细微的变化。
+
+![Xfce 4.18 版本看起来令人印象深刻!][1]
+
+Xfce 是目前最好的桌面环境之一。它因其简单性而受欢迎,是一个轻量级的选择。
+
+不像其他桌面环境,你不会看到 Xfce 定期的添加功能。所以,等待升级总是令人兴奋的。
+
+Xfce 4.18 是最新的版本,它增加了一些有用的功能和其他技术改进。让我重点介绍一下。
+
+### Xfce 4.18 的新变化
+
+![Xfce 4.18 有新的默认壁纸][2]
+
+虽然这不是一个完整的变化列表,但其中一些比较明显的变化包括:
+
+- 文件管理器的改进。
+- 桌面和面板的变化。
+- 更多的设置。
+- 新的壁纸。
+
+#### 文件管理器的改进
+
+![Xfce 4.18 文件管理器的分割视图][3]
+
+Xfce 的默认文件管理器 Thunar 在这个版本中得到了相当多的改变。作为许多 Linux 用户的最爱,Thunar 有一个干净直观的用户界面,使其对不同技能水平的人都很简单易用。
+
+在这个版本中,这个有用的工具获得了几个新功能。比如说:
+
+- 工具条上新的搜索图标使用户能够快速搜索文件和文件夹。
+- 你现在可以添加一个分割视图。
+- 启用独立的图像预览。
+
+还有一个有趣的新增功能,可以帮助你**高亮文件**,以便快速发现它们。你可以设置一个前景和背景颜色,如果你不想要这个功能,也可以重置。
+
+![xfce 4.18 文件高亮][4]
+
+你可以从文件的属性选项中访问这个功能。
+
+Thunar 文件管理器还增加了一些其他功能,包括:
+
+- 一个用于定制键盘快捷键的新标签。
+- 新的书签菜单。
+
+#### 精致的设置和桌面变化
+
+Xfce 桌面的大部分都保持不变。你不应该期待开箱后有不同的用户体验。
+
+虽然没有重大的视觉改造,但有细微的完善和功能改进。
+
+例如,你可以发现日历小部件的新能力。显示设置提供了更多选项,即使你没有连接多个显示器。
+
+Xfce 面板也有一些变化。
+
+![Xfce 4.18 面板设置][5]
+
+这些变化包括用像素而不是百分比来调整高度,以及一个新的 “保持面板在窗口上方” 选项。这使得窗口可以在面板下面延伸,而不是在顶部被切断。
+
+更不用说,时钟小程序现在可以自定义其字体类、字体大小和布局。
+
+![Xfce 4.18 时钟][6]
+
+#### 新壁纸
+
+当然,我们也得到了一些新的壁纸;你已经在本文的开头看到了新的默认壁纸。
+
+![Xfce 4.18 新壁纸集][7]
+
+如果你很好奇,你可以看看其他为 [壁纸竞赛][8] 提交的各种作品。也许你会发现别人不喜欢的东西。
+
+![Xfce 4.18 新壁纸集锦][9]
+
+这些是计划添加到背景集的其它候选作品。
+
+#### 其他变化
+
+除了之前提到的那些,这个版本还引入了一些其他变化。
+
+- 初步的 Wayland 支持,它允许 Xfce 在 Wayland 显示服务器上运行。
+- GTK4 的更新,提供了更好的性能和稳定性。
+- 一些核心应用程序的小更新,包括对 Xfdesktop、Xfwm4 和 Xfce4-panel 应用程序的改进。
+
+关于完整的变化列表,你可以参考 [官方博客文章][10]。
+
+### 获得 Xfce 4.18
+
+你可以通过软件库为滚动发布的发行版(如 Arch Linux)安装它。对于其他发行版,如果你不想自己做实验,你可能必须等待官方的更新。
+
+要想快速尝试,你可以安装 Xubuntu 23.04 日常构建版来获得这些功能。
+
+如果你使用的是其他为了稳定起见而不提供快速桌面环境更新的 Linux 发行版,如果你知道自己在做什么,你可以尝试手动安装。
+
+> **[下载 Xfce 4.18][11]**
+
+### 总结
+
+Xfce 4.18 是 Xfce 桌面环境的一次重大更新,有许多新的功能和改进。
+
+Thunar 文件管理器的更新尤其值得注意,因为它们为用户提供了更多的控制和定制选项。初步的 Wayland 支持和 GTK4 更新将提高性能和稳定性。
+
+总的来说,Xfce 4.18是一个受欢迎的更新,将改善 Xfce 用户的用户体验。

+Harmonoid:基本够用的漂亮的跨平台音乐播放器
+======
+
+![][0]
+
+幸运的是,[Linux 的优秀开源音乐播放器][1] 并不缺乏。过去我们已经介绍了多种选择。
+
+在这里,我重点介绍一款免费使用(但不是自由开源软件),可用于多种平台(包括 Linux、Windows 和 Android)的音乐播放器。
+
+### Harmonoid:Material Design 的直观用户体验
+
+![harmonoid player][2]
+
+Harmonoid 是用 Dart 语言编写的。它利用 [libmpv][3] 和 [mpv][4] 在桌面平台上实现媒体播放功能。
+
+它提供了一个优秀的用户界面。并且不使用 electron.js。所以,如果你讨厌 Electron,你可以试试这个。
+
+通常,你会在 Android 上看到应用具有 Material Design UI。如果你不知道,Material 是谷歌的开源设计系统。
+
+![harmonoid player info][5]
+
+没有多少创作者将它用于桌面应用。作为一种改变,Harmonoid 具有 Material Design 用户体验,可以同时做到快速和直观。
+
+这让 Harmonoid 为 Linux 用户呈现了独特的用户体验。动画感觉流畅且易于导航,并提供大量有价值的功能来帮助管理你的音乐库。
+
+![harmonoid url][6]
+
+如果你想要一个有良好 UI 和功能集的音乐播放器,我建议你尝试一下 Harmonoid。
+
+### Harmonoid 的特点
+
+![harmonoid player options][7]
+
+[Harmonoid][8] 可能看起来像一个简单的音乐播放器,但它包含了一些最有价值的功能。他们包括:
+
+- 跟唱功能,你可以找到歌词,或者你可以手动添加它们
+- 编辑歌曲详细信息,包括艺术家、年份、流派、曲目编号、专辑和标题
+- 轻松分类和排序你的音乐列表
+- 一个快速搜索功能来找到你要找的东西
+- 缓存元数据以在你每次加载时提供快速体验
+- 与 Windows 和 Linux 的良好集成支持
+- 支持在 Discord 中展示,可以显示你的音乐以及插图和播放按钮
+- 调整音乐的速度、音量和音高
+- 原始元数据读取器可读取你库中任何文件或歌曲的标签
+- 播放由 MPV 提供
+- .LRC 文件兼容性
+- 支持在线 URL(YouTube)和广播流
+- 跨平台
+- 多位艺术家支持
+- 深色/浅色模式
+
+除了这些之外,还有一些小功能可以发挥很大的作用,例如**无缝播放和上下文菜单集成,并且它通常是一个轻量级应用**。
+
+Harmonoid 应该非常适合想要同时播放音乐或整理收藏的用户。我会说它提供了两全其美的方法。
+
+![harmonoid settings][9]
+
+### 在 Linux 上安装 Harmonoid
+
+你可以从其 [下载页面][10] 获取 .deb/.rpm 包并将其安装在基于 Ubuntu 的发行版或 Fedora 上。
+
+此外,你需要使用以下命令安装 mpv 和 libmpv(对于 Ubuntu):
+
+```
+sudo apt install mpv lipmpv-dev
+```
+
+确保安装这些软件包可以让你用 Harmonoid 处理所有类型的文件进行播放。
+
+你还可以在 [AUR][11] 上找到基于 Arch 的发行版的 Harmonoid。要探索有关该播放器的更多信息,请访问其 [GitHub 页面][12]和[官方网站][8]。
+
+你是否尝试过 Harmonoid 在你的 Linux 系统上播放和整理音乐? 你最喜欢的 Linux 音乐播放器是什么? 在下面的评论中让我知道你的想法。

+
+虽迟但到!GNOME 的文件选取器在 18 年后增加了缩略图视图
+======
+
+> 一个长期缺位、也是急需的功能请求,终于通过了!
+
+![][1]
+
+如今,程序的用户界面是非常重要的;即使是最简单的交互也能决定用户的体验。
+
+GNOME 的文件选取器在查看文件时缺乏适当的缩略图预览,而是依赖于一个普通的列表视图。这对许多人来说可能是不直观的。
+
+多年来,缺乏这一功能也成了许多段子和讨论的主题。
+
+但是现在,在最初的 [功能请求][2] 提出 18 年之后,GNOME 终于可以支持一个合适的缩略图视图了。
+
+让我们来看看这个即将到来的对 GNOME 文件选取器的改变。
+
+### 该功能将随着 GNOME 44 到来
+
+![GNOME 文件缩略图视图][3]
+
+正如这个由 GNOME 开发者 [Matthias Clasen][4] 提供的早期构建截图所展示的。GNOME 上的文件选取器将具有一个缩略图视图。
+
+这就是它在 GNOME 43 上的样子:
+
+![GNOME 43 的文件选取器][5]
+
+**如何访问它?** 在 GNOME 上文件选取器的网格视图里,可以显示文件和文件夹的缩略图预览。
+
+现在将很容易区分文件管理器中的项目;不再需要打开一个文件来查看它包含的内容了!
+
+![GNOME 文件缩略图视图选取器][6]
+
+当这个功能到来时,你可以通过点击右上方的新视图切换按钮来启用它。
+
+**有什么变化?** 对于一个简单的功能添加来说,18 年是一个很长的时间。众多的技术原因使其实施成为一项艰巨的任务。
+
+但我很高兴,它终于来了。😃
+
+使之成为可能的原因之一是最近在 GTK 代码库中进行的废弃和现代化工作。
+
+> 💡 GTK 是 GNOME 的一切的核心的工具箱。
+
+而且,这些变化导致 [GtkListView][7] 和 [GtkGridView][8] 使用相同的数据模型来实现这个功能。
+
+**预期何时?** 这个历史上的 [合并请求][9] 已经被接受,并为其引入 GNOME 铺平道路。
+
+你可以期待它在 2023 年的某个时候与 GNOME 44 一起到来。
+
+我很期待!😁
+
+我们将把它作为 GNOME 44 功能提供的一部分来报道。所以,请继续关注我们的报道吧!

+
+在 Linux 上试试这个基于 Python 的文件管理器
+======
+
+![][0]
+
+> Dragonfly Navigator 是用 Python 和 Qt 编写的通用文件管理器。
+
+Dragonfly Navigator 是用 Python 和 Qt 编写的通用文件管理器。它易于安装和使用,并且是 Python 可以做什么的一个很好的例子。
+
+Python 是一种流行的语言有几个原因,但我认为它的主要优势之一是它对初级程序员和有经验的编码人员同样有用。你可以从一门语言中获得一些令人兴奋的东西,从 [绘制基本几何形状][1] 到 [抓取网页][2] 再到编写僵尸启示录 [游戏][3],或者编写你每天都可以使用的桌面应用。这就是 Dragonfly Navigator:一个人人都可以使用的桌面程序。
+
+### 安装 Dragonfly Navigator
+
+要安装 Dragonfly Navigator,首先从 [Git 仓库][4] 下载源代码。如果你使用的是 Debian Linux 或类似软件,请下载 `.deb` 文件。如果你使用的是 Fedora、CentOS、Mageia、OpenMandriva 或类似软件,请下载 `.tar.gz` 文件。
+
+Dragonfly Navigator 只有很少的依赖。因为你不是通过包管理器安装它,所以由你来解决这些问题。它只有两个依赖,所以使用你的包管理器(`dnf` 或 `apt`)找到并安装它们:
+
+- PyQt5,也称为 `python-qt5`
+- Python PIL,也称为 `pillow`
+
+### 启动 Dragonfly Navigator
+
+要启动 Dragonfly Navigator,请安装 `.deb` 文件(在基于 Debian 的系统上)或解压缩 `.tar.gz` 文件:
+
+```
+$ tar xvf dragonfly*gz
+```
+
+在基于 Debian 的系统上,Dragonfly Navigator 出现在你的应用菜单中。在其他系统上,你必须手动启动它,除非你 [手动安装][5]。
+
+现在,我没有安装它,所以我手动启动它:
+
+```
+$ cd dragonfly
+$ ./dragonfly
+```
+
+![Dragonfly Navigator is a two-panel file manager][6]
+
+### 双面板
+
+Dragonfly Navigator 是一个双面板文件管理器,这意味着它总是向你显示两个目录。在启动时,这两个目录恰好是你的主目录。你可以在任一面板中浏览文件和文件夹。它们的功能完全相同,只有当你开始复制或移动文件时你“位于”哪个面板中才重要。
+
+### 打开目录
+
+要打开目录,请双击它。默认情况下,该目录在同一面板中打开。但是,如果你想使用双面板布局,请在双击时按住 `Ctrl` 键以在另一个面板中显示其内容。
+
+### 打开文件
+
+要打开文件,请双击或右键单击它。
+
+是的,你可以右键单击文件将其打开。如果你习惯于右键单击调出上下文菜单,那么这需要一些时间来适应。不过,Dragonfly Navigator 中没有上下文菜单,你可能会惊讶地发现,当你将打开文件这一非常常见的操作减少到只需单击一次时,你会觉得自己节省了多少时间。现在可能看起来很傻,但相信我,你会逐渐珍惜它的。
+
+### 快速预览
+
+某些文件可用于快速预览,因此你不必在某个特定应用中打开它们。要预览文件,请将鼠标悬停在文件上,然后按键盘上的 `Alt` 键。预览出现在对面的面板中。
+
+![The second panel of Dragonfly Navigator can be used as a preview pane.][7]
+
+### 复制和移动文件
+
+要将文件从一个目录复制或移动到另一个目录(或从一个目录到另一个目录),有几个步骤。
+
+- 在一个面板中,进入目标目录。这是你要将文件复制到的位置。
+- 在另一个面板中,选择要复制的文件。
+- 单击 Dragonfly Navigator 中间条中的 “复制” 按钮。
+
+要移动文件,请按照相同的步骤操作,但要单击 “移动” 按钮。
+
+如果你不习惯双面板文件管理器,一开始会觉得很陌生。但是你仔细想想,在你常用的文件管理器中复制一个文件需要几个步骤(找到文件,打开另一个窗口,拖放等等)。做几次之后,它成为第二天性。
+
+### 选择文件
+
+通常,你单击一个文件或文件夹以使其成为你的活动选择。这可能与你当前的文件管理器没有什么不同,或者至少与你过去使用过的某些文件管理器没有什么不同。
+
+要选择一个范围内的多个项目,请单击一个文件,然后按住 `Shift` 键并单击另一个文件。你单击的两个文件之间的所有项目也被选中。
+
+要选择多个任意文件,请按住 `Ctrl` 键并单击要选择的文件。
+
+### Qt 和 Python 的力量
+
+Qt 工具包是一个强大的编程程序,Python 能够用它创建出色的应用。我在本文中只介绍了 Dragonfly Navigator 的基础知识,所以请下载它,阅读文档,点击并探索它,也许你会发现一个有趣的新文件管理器。

+
+Linux Mint 21.1 发布:大量的视觉变化和改进
+======
+
+> Linux Mint 21.1 带有一个新的默认主题和其他一些改进。
+
+![][1]
+
+Linux Mint 21 已经收到了它的第一个更新,即 **Linux Mint 21.1 “Vera”**。
+
+如果你想了解 Linux Mint 21 “Venessa”,我们的官方点评应该能让你尽快了解:
+
+> **[Linux Mint 21:最好的发行版变得更好了](https://itsfoss.com/linux-mint-21-review/)**
+
+这个版本与通常的小版本相似。它包括了对外观、感觉和功能的各种变化,这些变化可能看起来很细微,但会影响用户体验。
+
+让我们来看看主要的亮点。我们关注的是 Linux Mint 的 Cinnamon 版。
+
+### Linux Mint 21.1 Vera:有什么新内容?
+
+基于 **Ubuntu 22.04 LTS**,该版本的底层将继续使用 **Linux 5.15 LTS** 内核。
+
+![][2]
+
+#### 👀 焕然一新的用户界面
+
+当你第一次启动进入桌面时,你应该很快注意到光标的新外观。它默认采用了新的 Bibata 主题。
+
+![][3]
+
+光标、图标主题列表增加了一些新的主题,如 Yaru、Breeze 和 GoogleDot,以及传统的 DMZ 主题。
+
+![][4]
+
+除了传统的 Mint-X、Mint-Y 和 Mint-Legacy 主题外,用户还可以找到一组独特的应用图标主题,这包括 Papirus、Breeze、Numix 和 Yaru。
+
+![][5]
+
+另一件你可能会注意到的有趣的事情,默认的强调色不再是传统的绿色,这是因为 **桌面主题现在换成了 Aqua**。强调色库提供了更多鲜艳的颜色,使桌面看起来更干净、更有吸引力。
+
+对于那些希望恢复传统外观的人,你可以在主题中选择 “Mint-Y-Legacy”。
+
+此外,以前在桌面上可见的 **电脑、主文件夹、网络和垃圾箱图标** 被默认删除,它们可以在文件管理器中访问。主文件夹的图标则显示在面板上。如果你想恢复以前的方式,你可以通过进入 系统首选项 来恢复。
+
+#### ✨ 增强的驱动器管理器
+
+由于驱动器管理器在用户模式下运行,所以当你启动它时不再要求输入密码。
+
+![][6]
+
+有专门的屏幕来显示离线连接和检测到 现场 USB 时的情况。你也应该发现挂载现场 USB 比以前更顺畅了。
+
+![][7]
+
+对它也进行了一些修复。
+
+Packagekit 现在可以清除已删除的驱动程序和软件包。这解决了一个众所周知的问题,即用户想要在不同版本的英伟达驱动之间进行切换。
+
+此外,Debconf 也进行了修补,以解决启用安全启动时英伟达驱动程序的一个问题。
+
+#### 👨💻 Flatpak 集成和软件管理器的改进
+
+很高兴看到 软件管理器 和 更新管理器 都支持 Flatpak 了。
+
+安装和更新 Flatpak 应用程序的过程没有什么不同,应该是很容易的。
+
+![][8]
+
+例如,软件管理器已被更新,以帮助区分用户正在查看的应用程序是哪个版本:Flatpak 版本还是系统版本。还有一个下拉框,用于在一个应用程序的系统版本和 Flatpak 版本之间切换。
+
+卸载 Flatpak 应用程序和快捷方式不再需要密码了。在进行多项操作时也是如此。
+
+#### 🔨 对 XApp 的改进
+
+用户现在可以配置登录屏幕的光标大小和主题。以前,这些设置是全局设置。
+
+另一方面,Warpinator 获得了更好的安全性,而 WebApp 管理器 在编辑 WebApp 时具有额外的设置,包括私人浏览和导航栏。
+
+#### ⭐ 新的 ISO 验证工具
+
+在大多数情况下,人们想验证一个下载的 ISO 镜像的完整性。
+
+因此,更简单方便的方法是,你可以通过右击 ISO 镜像,选择 “验证”来完成。这就打开了 ISO 验证工具,你可以在那里填写必要的细节来进行验证。
+
+![][9]
+
+值得注意的是,对于 Linux Mint 和 Ubuntu 的 ISO 镜像,SHA256sum 和 GPG 文件的 URL 是自动填写的。
+
+#### 🎨 Cinnamon 5.6 桌面
+
+Linux Mint 的旗舰桌面环境也有一些微小的视觉更新和变化。
+
+在桌面的面板上,你会注意到主菜单和应用程序之间有一个细细的分隔线。像 Windows 一样,在最右边的角落里增加了一个新的角栏小程序,可配置,并支持创新的操作。
+
+![][10]
+
+说到视觉效果,默认的文件管理器 Nemo 已经经历了一些变化:
+
+- 当选择一个或多个项目时,只有名称保持高亮,而图标则没有。
+- 日期现在以等宽字体显示。
+- 路径栏也得到了一些改进。
+
+你可以毫不费力地访问 显示设置,因为它的快捷方式已被添加到桌面的上下文菜单中。
+
+### 🛠️ 其他改进措施
+
+其他两个桌面环境已经分别更新到 **MATE 1.26** 和 **XFCE 4.16**。
+
+美术作品集也得到了扩展,包括几张很酷的壁纸。
+
+虽然我们只介绍了这个版本的主要亮点,但你可以通过 [官方更新日志][11] 了解更多细节。
+
+### 获得 Linux Mint 21.1
+
+现有的 Mint 用户应该得到通知,可以通过更新管理器轻松升级到 Mint 21.1。
+
+那些想要重新安装 Linux Mint 的人可以从 [官方下载页面][12] 获得 ISO。
+
+> **[Linux Mint 21.1][12]**
+
+如果你的网络较慢或不稳定,你也可以 [使用 Torrent 链接][13]。

+开源电动汽车充电解决方案
+======
+
+> 利用太阳能、硬件和开源来建立你自己的电动车充电站。
+
+![][0]
+
+也许你讨厌在寒冷或者酷热的时候加油,也许你关心环境问题。也许不断上涨的油价和通胀让你不得不考虑怎么更合理的安排开支。也许你只是认为电动汽车看起来很酷。不管什么原因,你都会因为即将拥有一辆电动汽车而感到激动,激动的不仅仅只有你。电动汽车的市场份额将在 [2040 年增长到 30%][1] 。[美国政府提供了一个简易的比较工具][2],用来展示维护一辆电动汽车的花费比维护一辆化石燃料汽车要少很多。尽管如此,电动汽车的充电费用仍然会给你的钱包带来沉重的负担。
+
+通常,解决成本问题的最优雅的方法之一是应用开源原则来加速创新。幸运的是,在电动汽车充电领域已经找到了一种获得低成本电力和充电桩的方法。
+
+为了控制电动汽车充电的成本,首先,你需要低成本的电力。在过去,这意味着从石油倒退到煤炭。如今,能将太阳能直接转化为电能的 [光伏发电][3](PV) 设备提供的电力通常被认为成本是最低的。煤炭公司正在因为无法继续与清洁的太阳能竞争而破产。这也是 [太阳能发电在世界各地都爆炸性增长][4] 的原因。许多房主把 [太阳能电池板放到他们的房顶][5] 或者后院的支架上,以满足他们家庭的电力需求。但是,如果你的屋顶面积有限或者后院很小,你怎样才能使用太能能给你的电动汽车充电呢?
+
+### 开源光伏停车篷
+
+大型企业正在采取的一个方法是在他们的停车场上建造一个光伏顶篷。如果你自己想做一个,一个新的 [研究][6] 提供了三种新型开源光伏顶篷系统全面的机械和经济方面的分析。
+
+- 使用纯木材的单一停车位横跨系统
+- 使用木材和铝的双停车位横跨系统
+- 使用木材和铝的悬臂系统
+
+这些设计是以 5 * 6 个停车位的样式呈现的,但是这三个系统都可以扩展到任何需要的停车位数量。包括一个 6 千瓦的家用单车充电系统(如下图)。所有的支架都有 25 年的预期寿命来配合标准的光伏保修。
+
+![Image of a single car PV canopy.][7]
+
+这些开源光伏顶篷都是为了抵御加拿大残酷的冬天而设计的,它们遵循加拿大严格的建筑规范。所以,不管你住在其他任何地方,这些系统的设计都仍然可以为你工作。顶篷的 [完整设计][8] 以及材料清单,包括基本说明都有提供。它们以开源许可的方式发布,保证任何人都可以依照关于 DIY 太阳能收集器的免费书籍 《[拥抱太阳][9]》 制作它。
+
+前面提到的 [研究][6] 结果显示,开源设计比专利产品的成本低很多。单跨系统可节省成本 82% 到 85%,双跨系统节省成本 43% 到 50%,悬臂系统节省 31% 到 40% 。
+
+最重要的是,这些设计给你提供了足够多的能源(如果你只是正常通勤)来满足你的充电需求。在运行的第一年,光伏顶篷可以提供目前市场上效率最低的电动汽车充电所需电量的 157% 。
+
+![Image of an OpenEVSE charging station.][10]
+
+### 开源电动汽车充电桩
+
+减少电动车维护成本的另一个办法是安装一个开源的电动车充电桩。[OpenEVSE][11] 是一个基于 Arduino 的充电桩,由 [开源软件][12] 和硬件组成,可以以 DIY 的方式制作。它们体积小,重量轻,便于携带,你可以在家里或者旅途上使用它们。
+
+OpenEVSE 为世界各地的许多电动车制造商提供充电站。你可以根据自己的需求调整它。OpenEVSE 已经相当成熟,支持许多先进的功能,包括可调电流,温度检测和实时功率显示。你可以购买预先组装好的硬件马上体验。如果你想体验更多的乐趣,可以购买一套套件自己动手制作。
+
+![Image of the OpenEVSE kit.][13]
+
+我希望未来可以看到更多关于电动汽车充电解决方案的设计。睁大眼睛,撸起袖子加油干,享受组装你的开源太阳能充电桩的乐趣。

+5 个即将推出的可能会挑战 VS Code 的代码编辑器
+======
+
+> 这些有趣的代码编辑器可能会在 2023 年取代 VS Code!
+
+![5 Upcoming Code Editors that May Challenge the Supremacy of Visual Studio Code][1]
+
+嗯,2022 年即将结束。
+
+我们推出了针对 Linux 发布的新的卓越代码编辑器,从 [Lite XL][2] 到 [Pulsar][3] 等。
+
+因此,为了纪念这一点,我编制了这份即将推出的 Linux 代码编辑器列表,它们很有可能挑战 [VS Code][4] 的霸主地位。
+
+让我带你了解它。
+
+### 1、Pulsar
+
+![pulsar][5]
+
+[Pulsar][6] 是一个社区主导的开源代码编辑器,旨在替代著名的 Atom 代码编辑器。
+
+它使用与 Atom 相同的代码库,有一个开源的后端(得益于逆向工程的工作),更新了依赖性。
+
+他们有计划在不久的将来对其进行改进。
+
+它可以从 [官方网站][7] 下载,但请记住,它还处于早期开发阶段。
+
+### 2、Atom 社区版
+
+![atom community][8]
+
+“[Atom 社区版][10]” 也是从现已停止维护的 Atom 编辑器的 [灰烬][9] 中重生的,它是一个旨在接管其前身的概念和想法的项目。
+
+他们的目标是从提供最基本的特性开始,并使其与 [atom-ide-ui][11] 包中的可用功能相媲美。
+
+它可能会有更多东西,但就目前的形式而言,我现在不建议新用户这样做。与 Pulsar 相比,他们的长期目标略有不同,这使它成为另一个值得一看的项目。
+
+但是,到 2023 年,情况可能会有所不同。
+
+尽管如此,那些喜欢冒险的人可以使用 [源代码][12] 来构建它。
+
+### 3、Lapce
+
+![lapce][13]
+
+一个轻量级和快速的开源代码编辑器?
+
+这就是 [Lapce][14]!
+
+它是一个基于 Rust 的开源代码编辑器,专注于提供这样的体验。
+
+我们在它处于 pre-alpha 阶段时对其进行了介绍,但在 2023 年它可能会引起注意。
+
+### 4、Zed
+
+![zed breadcrumbs][15]
+
+[Zed][16] 是即将推出的代码编辑器,旨在挑战 VS Code 的统治地位。
+
+它有许多功能,例如实时协作、极简界面、代码动作、命令面板等 [更多功能][17]。
+
+事实上,Atom 的创始人 [Nathan Sobo][18] 是这一切的幕后推手,并将其称为 Atom 的“_精神继承者_”。
+
+### 5、Lite XL
+
+![lite xl][19]
+
+[Lite XL][2] 是一个用 Lua 编写的开源代码编辑器,仅使用 3MB 的存储空间和大约 20MB 的内存。(与 VS Code 的 ~550 MB 相比)。
+
+如果你正在寻找一个完全最小化的代码编辑器,它可能会合你的口味。
+
+你现在可以从 [官方网站][20] 获取它,它会定期更新,预计 2023 年也会如此。
+
+**好了,这是这份名单的结束,也是 2022 年的结束。** 😃
+
+_我可能错过了一些代码编辑器,我知道你会在评论部分告诉我。随时分享你的想法!_

+Unity 正在积极开发,预告 7.7 版
+======
+
+> Unity 7.7 版的更新计划为该桌面环境带来一些视觉上的改革。
+
+![][1]
+
+Unity,经典的桌面环境,从 2010 年到 2017 年都是 Ubuntu 的一部分,将收到一个大的新版本。你可以期待它在 2023 年的某个时候发布,但目前还没有具体的发布日期。
+
+但不是由 [Canonical][2] 发布。
+
+**如果你不知道:** Unity 的开发由一位年轻的开发者 [Rudra Saraswat][3] 接手,他也是 [Ubuntu Unity][4] 衍生版的创造者,这是 Ubuntu 的一个官方特色版。
+
+在最近的一篇 [博文][5] 中,Rudra 向我们揭示了 Unity 7.7 的一角和即将到来的各种改进。
+
+让我带你看看这些。
+
+### Unity 7.7 值得期待的地方
+
+![unity 7.7 一窥][6]
+
+这次披露的内容有很多,其中包括:
+
+- 更新的欢迎应用程序
+- UWidgets
+- 改进的仪表盘
+- 面板的调整
+- 增强的通知指示器
+
+#### 更新的欢迎应用程序
+
+![][7]
+
+一个新的欢迎应用程序将被引入 Unity,它基于 Ubuntu Flutter 社区开发的原型(用 [Flutter][8] 编写)。
+
+这个应用程序将不只限于一个发行版,而是适用于 Unity 所支持的所有发行版。
+
+#### UWidgets
+
+![][9]
+
+终于有了,Unity 桌面上的小部件?像 KDE 一样?
+
+好吧,在 Unity 中引入用 Python 编写的小部件,应该很简单就可以设置(只是复制几个文件的问题)。
+
+屏幕截图展示了一堆小部件,如时钟、系统监视器、Spotify 的小部件等等。
+
+这还不是全部,Rudra 还提到:
+
+> 我们将为 UWidgets 建立一个网页商店/仓库,在那里你可以提交你自己的小部件,或者下载并试用 Unity 7.7 上所有这些令人惊叹的小部件。
+
+这应该会使用户更容易找到和下载小部件!
+
+#### 改进的仪表盘
+
+![][10]
+
+仪表盘也被刷新了,新的设计基于 Unity 7 的原始设计概念(在 Canonical 放弃它之前)。
+
+按照截图,它应该不会占用大量的屏幕空间,而且还很有用。
+
+#### 面板的调整
+
+![][11]
+
+现在的面板比之前的版本略大且更精致。
+
+#### 增强的通知指示器
+
+![][12]
+
+这对 Unity 来说是一个巨大的可用性改进;用户现在终于可以利用一个适当的通知指示器了。
+
+它将显示与你的应用程序、系统和更多相关的基本通知。
+
+#### 其他变化
+
+![][13]
+
+一些更有用的技术改进包括:
+
+- unity-control-center 的外壳 UI 得到了改进
+- 默认的面板不透明度降低到 0.75
+- 默认的启动器图标尺寸被缩小了
+- 启动器按钮(Ubuntu 图标)被替换为半透明的图标,类似于 Ubuntu Unity 21.04 的启动器按钮。
+
+_对 Unity 7.7 感到激动?请在下面的评论中告诉我你的想法。_

+
+什么是 Firefox ESR?如何在 Ubuntu 中安装它?
+======
+
+![][0]
+
+Ubuntu 的 Snap 版本你不喜欢?不喜欢每一次 Firefox 的发布都要不断地改变东西?如果你重视稳定性而不是功能,你可以试试 Firefox ESR 版本。
+
+### 什么是 Firefox ESR?
+
+Firefox ESR 是 Firefox 的特别版,它不一定像普通版那样每月都有新功能,但它能提供稳定和安全的浏览体验。这适用于企业、组织和机构,在这些地方,稳定性和核心功能比闪亮的新功能更重要。
+
+可以把 Firefox ESR 看作是 Linux 发行版的长期稳定版本。它们不一定得到全新的功能,但它们会得到定期的安全和维护更新。这给了用户一个熟悉和稳定的环境。
+
+#### 你为什么要关心 Firefox ESR?
+
+Firefox 几乎每个月都会发布一个新版本。它包含安全和功能更新。
+
+但有些人可能不喜欢各种功能的加入和删除。如果在更新之后,你一直想知道某些设置到哪里去了,或者不喜欢与以前不同的东西,Firefox ESR 可能值得一试。
+
+基本上,如果你更看重稳定性而不是新功能,那么 Firefox ESR 就适合你。这也是 Debian 中携带的 Firefox 版本,Debian 以其是市场上最稳定的发行版之一而闻名。
+
+让我告诉你如何在 Ubuntu 上获得 Firefox ESR。**你可以同时安装 Firefox 和 Firefox-ESR 两个版本。它们的标识没有视觉上的区别,所以你必须注意你打开的是哪个火狐版本。**
+
+### 在 Ubuntu 中安装 Firefox ESR
+
+在进入安装之前,让我来分享一下普通 Firefox 和 Firefox-ESR 之间的版本差异是什么。在写这篇文章的时候:
+
+- Firefox 的版本是 **107.0-2**。
+- Firefox-ESR 目前的版本是 **102.5.0esr**。
+
+所以,如果这对你来说没问题,让我们看看第一个方法。
+
+#### 方法 1:使用 PPA 安装 Firefox-ESR
+
+Firefox-ESR 在 Ubuntu 的默认仓库中是不可用的,所以你可以使用 PPA。
+
+PPA 只不过是一个由个别技术人员或开发者维护的仓库,拥有默认仓库所没有的东西。
+
+如果你想了解更多关于 PPA 的信息,我建议你查看我们的其他指南,其中解释了 [如何在 Linux 上使用 PPA][1]。
+
+打开你的终端,使用给定的命令来添加 Firefox-ESR 的 PPA:
+
+```
+sudo add-apt-repository ppa:mozillateam/ppa
+```
+
+然后按回车键确认你要添加 PPA:
+
+![add firefox esr repository in ubuntu][2]
+
+完成后,你需要更新 Ubuntu 中的仓库索引,以便从这些变化中生效:
+
+```
+sudo apt update
+```
+
+现在,你可以通过使用给定的命令来安装 Firefox-ESR:
+
+```
+sudo apt install firefox-esr
+```
+
+接下来,你可以使用给定的命令来检查你系统中 Firefox-ESR 的安装版本:
+
+```
+firefox-esr -v
+```
+
+![check installed version of firefox esr in ubuntu][3]
+
+如何从 Ubuntu 卸载 Firefox-ESR?
+
+如果 ESR 对你的工作来说感觉太过时了,或者由于其他原因你想从你的系统中删除它,你可以按照以下步骤删除 Firefox-ESR 包和仓库。
+
+首先,让我们用下面的方法删除 Firefox-ESR 包:
+
+```
+sudo apt remove firefox-esr
+```
+
+现在,你可以使用给定的命令来 [从 Ubuntu 删除 PPA][4]:
+
+```
+sudo add-apt-repository --remove ppa:mozillateam/ppa
+```
+
+这就完成了!
+
+#### 方法 2:使用 Snap 安装 Firefox-ESR
+
+不管你爱不爱它,Snap 在 Ubuntu 上是预先配置好的,我发现使用 Snap 是安装软件包的一个很好的方法,特别是当你想避免从源码构建它们或使用 PPA 时。
+
+使用 Snap 安装 Firefox-ESR,你需要做的就是使用给定的命令:
+
+```
+sudo snap install firefox --channel=esr/stable
+```
+
+![install firefox esr using snaps in ubuntu][5]
+
+如何删除 Firefox-ESR Snap?
+
+要删除 Firefox-ESR(snap 包),请使用 [snap remove 命令][6]:
+
+```
+sudo snap remove firefox
+```
+
+这就完成了!
+
+### 总结
+
+我在本指南中解释了如何使用多种方法在 Ubuntu 中安装 Firefox-ESR。我个人使用 Firefox-ESR 而不是普通版本,因为我有随机崩溃的情况。
+
+自从我改用 Firefox-ESR 后,一切都变得稳如磐石。如果你也有同样的问题,你应该试一试。

+
+衡量你的开源软件使用情况的 8 个方法
+======
+
+![][0]
+
+> 想知道如何为你的开源软件项目收集使用指标?考虑一下使用这些替代方案的利弊。
+
+我们这些支持开源项目社区的人经常被问到很多有关使用指标的问题。这些指标通常是为了通过用户量和知名度来衡量软件的重要性。我们一般都想知道有多少人使用该软件,有多少次安装,以及有多少人生活接触过它。
+
+但简而言之,我们尚无法直接回答上述问题。
+
+如果你想要寻找一个明确的解决方案,那很抱歉要让你失望了。有关使用指标的问题,没有人有完美的答案,至少没有准确的答案。
+
+好消息是,有一些近似的和替代指标至少能够部分地满足你对软件使用情况了解的渴求。本文探讨了这些替代方案以及它们的优点和缺点。
+
+### 下载量
+
+当你浏览提供软件的网站时,你通常可以看到软件的下载次数。映入我脑海的一个例子是 Firefox ,它曾经有一个下载计数器。Firefox 的下载量是一个印象深刻的数字,给人的印象是 Firefox 是一个流行的浏览器,在一段时间内确实如此。
+
+然而,个人行为会直接影响这一数字的准确性。举例而言,当一个人定期重置他们的设备时,每一次重建都会引发一次独立的下载。考虑到这一现实,需要设计一种方法从下载量中去除几十次(或许是几百次)的下载次数,因为那是一个人。
+
+下载量不仅会高估使用量,还会低估使用量。例如,一个系统管理员可能会下载一个新版本的 Firefox 一次并将其拷贝到 U 盘上,然后安装到数百台设备上。
+
+下载量指标是易于收集的,你可以在服务器上记录每一个下载请求。问题在于你不知道在这些软件下载以后会发生什么。下载它的人是否如预期的那样使用软件,还是遇到了问题而放弃了它。
+
+对于开源项目而言,你可以考虑各种下载量指标,比如来自以下途径的下载指标:
+
+- 项目官网
+- 包管理器,比如 npm、PyPi 和 Maven
+- 代码仓库,如 GitHub、GitLab、Gitee 等
+
+你可能还对源代码的下载量感兴趣,因为下游项目更可能使用源代码形式(参见 [《如何衡量你的开源项目的影响》][1]一文)。相应的下载指标包括:
+
+- 从代码仓库克隆的数量,比如 GitHub、GitLab 和 Gitee
+- 从官网下载的归档文件(tar、zip)的数量
+- 通过像 npm、PyPi 和 Maven 这样的包管理器下载的源代码数量
+
+源代码的下载指标比二进制代码的下载指标更不可靠(虽然尚无相关研究表明如此)。试想一下,一名开发人员想要你的最新版本的源代码,并将他们的构建管道配置为每次构建都克隆你的仓库。再想象一下,一个自动构建过程失败了,它试图重新构建而不断地克隆你的版本库。你还可以考虑这样一个下载量低于预期的场景——源代码仓库在某些地方缓存了,下载来源是由这些缓存所提供的。
+
+> **[相关阅读:跟踪你的开源社区的 5 个指标][2]**
+
+总而言之,下载量指标是用于提供当前使用情况和探测趋势的很好的指征。我们无法明确地定义一次下载是如何转化为使用的。不过我们可以认为增加的下载量是更多潜在用户的标志。举例而言,如果你为你的软件做了广告并在活动期间得到了更高的下载量,可以合理地假定广告推动了更多人下载该软件。下载行为的来源与元数据还可以提供额外的与使用行为相关的内容。你的软件的哪些版本仍在使用中?什么操作系统或者特定语言的版本更加流行?这有助于社区决定将哪个平台的软件作为支持与测试的优先选项。
+
+### 议题
+
+作为一个开源项目,你可能有一个议题追踪器。当某个人提出一个议题时一般有两个目标,报告一个漏洞或者请求增加一项功能。提议者很可能已经使用过你的软件了。作为一名用户,他可能发现了一个漏洞或者发现了对一个新功能的需求。
+
+很明显,大多数用户不会执行额外的步骤来提交议题。提议者是我们的忠实用户,我们对他们表示感谢。此外,通过提出议题,他们已经成为了非代码贡献者,他们也有希望成为代码贡献者。经验法则是大约每 10000 名用户中,可能有 100 名提议者,以及 1 名代码贡献者。当然取决于用户类型,上述比例可能有出入。
+
+回到指标问题,你可以将提议者数量作为评估使用量的下界。相关的指标包括:
+
+- 提议者数量
+- 活跃提议者的数量(在过去 6 个月内提出议题的提议者)
+- 同时有代码贡献的提议者的数量
+- 尚未解决的议题的数量
+- 对议题发布的评论数量
+
+### 邮件列表、论坛和问答网站
+
+很多开源项目都拥有用户邮件列表、论坛,并且出现在类似 Stack Overflow 的问答网站上。与提问者一样,在这些地方发帖的人可被视作用户的冰山一角。与邮件列表、论坛和问答网站上的社区活跃程度相关的指标也可用于反映用户数量的上升或下降。相关指标可以集中于以下地方的活动,包括:
+
+- 用户邮件列表的订阅量
+- 论坛用户的数量
+- 问题的数量
+- 答案的数量
+- 发布信息的数量
+
+### 上报功能
+
+为了获得精确的用户数量,一个方案是让软件在使用时上报信息。
+
+这是令人毛骨悚然的。想象一下,系统管理员的防火墙报告了一个非预期的到你的服务器的网络连接,你不仅无法再收到软件报告(被防火墙拦截了),恐怕连你的软件也可能在未来被禁止使用。
+
+负责任的设置上报功能的方式为设置一项可选服务来检查更新并让用户知道使用最新版本。另一项可选功能可以集中在使用遥测上,你可以通过该功能询问用户是否允许匿名上报软件使用情况。如果经过深思熟虑的实施,这种方式可以允许用户通过他们使用软件的方式帮助优化软件。用户可以持有这样的意见:我一般不允许这种使用信息的分享;但对于一些软件,因为希望开发人员在长期内将软件优化得更好,我愿意这样做。
+
+### 星标与复刻
+
+星标与复刻是如 GitHub、GitLab、Gitee 等社交化编程平台的功能。这些平台上的用户可以给一个项目加星标。为什么他们要给项目加星标呢?GitHub 的文档作出了解释:你可以给一个仓库和主题加星标,以跟踪感兴趣的项目,和在你的新闻订阅中发现相关的内容。给一个项目加星标与将其加入书签的效果一样,并且还提供了一种向项目仓库的维护者展示赞赏的方式。星标的数量已经成为了项目流行程度的标志。当一个项目发布重大公告并获得相当的关注时,项目的星标数量会呈上升趋势。星标的数量指标并不反映软件的使用量。
+
+在社交化编程平台上的复刻是将项目仓库复制一份在自己名下。仓库的非维护者可以在他们自己的克隆仓库中做修改,并将修改通过拉取请求(PR)的方式提交审核。复刻比星标更能反映软件社区的规模。开发者也可能为了保存一份代码副本而克隆一个项目,以便在原始仓库消失后他们仍能访问代码。因为复刻功能在代码贡献工作流中的应用,复刻量是衡量开发社区的良好指标。复刻量通常也不反映非开发人员的使用,因为非开发人员一般不创建复刻。
+
+### 社交媒体
+
+包括 Facebook、Instagram、LinkIn、Reddit、Twtter 等社交媒体平台提供了相同兴趣的人们聚集的平台。采用社交媒体策略,开源项目可以通过在平台上设置相应的聚集空间来吸引对项目感兴趣的人们。通过这些社交媒体途径,开源项目可以分享项目新闻、更新,指出贡献者和用户。这些社交媒体途径还可以用于认识那些本不会通过其他途径与项目互动的人。
+
+我在犹豫是否建议关注以下指标,因为它与软件的真实使用量没有清晰的联系,并通常需要分析其中的积极、消极和中性的情绪。人们可能因为很多不同的原因对你的项目感到激动而关注它,但并不实际使用它。然而与之前已经讨论过的指标一样,能够在社交媒体上吸收人群本就是项目受关注的整体指标。不同社交媒体平台的指标包括:
+
+- 关注者与订阅者的数量
+- 消息的数量
+- 活跃的消息作者的数量
+- 喜欢、分享、回复以及其他交互的数量
+
+### 网站分析与文档
+
+网站流量也是一个有用的指标。这一指标主要受到你的服务范围以及市场营销活动影响,而不是用户量。然而,我们还有一张王牌:我们的用户文档、教程、手册以及 API 文档。我们可以发现我们的网站以及文档中的什么主题更引人注意。文档的访问者数量应当大致随着软件的使用者数量增长而增长。因此我们可以通过网站的访问量探知对项目的普遍兴趣,并进一步通过观察文档的访问者来观察用户风向。这些指标包括:
+
+- 网站访问者数量
+- 文档访问者的数量
+- 访问者在你的网站与文档上所花的时间
+
+### 活动
+
+活动的指标可以在你主持与项目相关的活动时使用。这是建立社区的很好的方式。有多少人提交摘要想要在你的活动中发言?有多少人出席你的活动?不论是在线下活动还是线上活动这可能都很有趣。当然,你如何推广你的活动在很大程度上决定有多少人到场。同时你可以将自己的活动与人们出行的大型活动放在一起以方便人们参加你的活动。只要你使用一贯的活动策略,你可以通过演讲者提交的材料与参会者注册的增加来表征软件受欢迎程度与用户群的增加。
+
+你并不需要举办你自己的活动来收集有用的指标。如果你在开源活动中主持有关你项目的讨论,你可以衡量有多少人出席主要关注你的项目的会议。像 [FOSDEM][T1] 这样的活动,一些讨论特别聚焦于开源项目的更新与发布,会议室中都挤满了人(像 FOSDEM 的所有会议一样)。
+
+你可以考虑如下指标:
+
+- 以你的项目为中心的活动的出席人数
+- 提交到以你的项目为中心的活动的演讲数量
+- 以你的项目为中心的演讲的出席人数
+
+### 关于估算开源软件使用的结论
+
+正如我们已经如上展现的,有很多指标可以反映软件使用的趋势,没有一个指标是完美的。在大多数情况下,这些指标可能被个人行为、系统设计和噪音所严重影响。因此,考虑到每一个指标的相对不确定性,我们建议你不要孤立地使用任何一个指标。但是如果你从不同的来源收集了一系列的指标,你应当能够探测到用户行为与软件使用的趋势。如果你有办法在多个具有共性的开源项目中比较同一组指标,例如类似的功能、强大的相互依赖性、在同一基础设施上托管,以及其他特征,你就可以提升你对用户行为基线的感知。
+
+需要注意的是,在这篇概述中,我们选择突出能够评估直接使用情况的指标。而大多数软件都依赖于其他各种软件包,如果我们不提及作为软件依赖链的一部分而被间接使用的严重影响,这就是我们的疏忽。因此,我们建议将上下游依赖的合计数量作为你的分析中的另一层内容。
+
+最后,作为数据与指标的使用者,我们鼓励你认识到你的利益相关方的权利与责任。你发布的任何指标都有可能影响用户行为。最好的做法是经常一同分享你的背景信息——基础、来源、估算方法和其他关键上下文信息,这有助于其他人解释你的结果。
+
+感谢 [CHAOSS][T2] 社区在爱尔兰都柏林举行的 CHAOSScon EU 2022 上的富有洞察力的对话,上述对话激发这篇博文的想法。我们还要感谢 CHAOSS 社区的成员审阅并帮助优化本文。

+
+如何在 Linux 中更新 Flatpak 软件包
+======
+
+![][0]
+
+我相信几乎所有的 Linux 用户都会保持他们系统的更新。
+
+但这种更新通常是针对默认的 [包管理器][1]。例如,[更新 Ubuntu][2] 往往意味着更新所有的 APT 软件包。
+
+然而,还有其他的打包格式,如 Snap 和 Flatpak。Snap 应用程序会自动更新,但 Flatpak 不会。
+
+那么你如何更新 Flatpak 软件包呢?好吧,你可以用这个命令来更新所有已安装和可更新的 Flatpak 包:
+
+```
+flatpak update
+```
+
+这很简单。但让我再讨论一下关于更新 Flatpak 的一些事情,比如说:
+
+- 更新所有或特定的 Flatpak 包
+- 通过软件中心更新 Flatpak 包
+
+让我们先从终端的方法开始。
+
+### 方法 1:使用终端来更新 Flatpak 包
+
+首先让我从最实用的方法开始,你也应该从这个方法开始。
+
+#### 更新每一个过时的 Flatpak 包
+
+更新现有的 Flatpak 包的整个目录是很容易的。
+
+输入给定的命令,就可以得到过期包的列表:
+
+```
+flatpak update
+```
+
+![update flatpak packages in linux][3]
+
+你只需输入 `Y` 并按下回车键,就能搞定每一个更新。
+
+#### 更新特定的 Flatpak 包
+
+要更新特定的软件包,你需要可以更新的软件包的列表。你用的是你之前看到的那个命令。
+
+```
+flatpak update
+```
+
+![update flatpak packages in linux][4]
+
+从输出中复制你要更新的软件包的名称。在以下命令中使用软件包的名称:
+
+```
+flatpak update package_name
+```
+
+例如,如果你想更新 Telegram,下面的命令可以完成这项工作:
+
+```
+flatpak update org.telegram.desktop
+```
+
+![update specific package in flatpak][5]
+
+这就完成了。
+
+### 方法 2:从软件中心更新 Flatpak 应用
+
+有 Flatpak 内置支持的发行版会在软件中心提供 Flatpak 应用的更新。Fedora 和 Linux Mint 就是这样的发行版。
+
+但如果你使用的是 Ubuntu,你就需要在 GNOME 软件中心添加 Flatpak 支持:
+
+```
+sudo apt install gnome-software-plugin-flatpak
+```
+
+完成后,你将在 Ubuntu 中拥有两个软件中心。这是因为默认的软件中心不是 GNOME 的,而是 Snap Store。
+
+从系统菜单中打开这个新的软件中心:
+
+![open software center in ubuntu][6]
+
+进入“更新”页面,你会发现过时的软件包列表。这包括 APT 和 Flatpak 软件包。
+
+![update flatpak from software center][7]
+
+在这里,你可以一次更新所有的软件包,或者你可以有选择地更新什么。
+
+### 总结
+
+许多 Linux 桌面用户往往忘记更新 Flatpak 软件包,因为它们不包括在定期的系统更新中。
+
+由于 Flatpak 是一个沙盒式的打包解决方案,你可能不会面临任何与过时的软件包有关的问题,但你肯定会错过新的功能和修复。
+
+这就是为什么我建议每隔几周运行一次 Flatpak 更新命令。
+
+我希望你喜欢这个快速的 Flatpak 小技巧。

+如何在 Linux 中降级 Flatpak 软件包
+======
+
+![][0]
+
+> Flatpak 软件包的一个鲜为人知的特点是,它允许你对已安装的应用程序进行降级。下面是如何使用它的方法。
+
+从技术上讲,小版本或次要更新是为了解决问题。但是,当某些更新破坏你当前的工作流程时,情况可能会变得更糟。
+
+无论是 Flatpak 包还是 Snap,当出现问题时,一切都会在某个时候崩溃。作为一个沙盒打包方案,它可能不会影响整个系统,但如果你遇到一个让你的应用体验变差的错误,你可能会后悔更新。
+
+比如之前 [Black Box][1] 的更新就带来了一些错误,无法选择文字!开发人员现在已经解决了这个问题,但在他们没有解决之前,我降级了那个特定的包以使其正常工作。
+
+所以,如果你想降级特定的 Flatpak 应用,你可以按照本指南进行操作。
+
+### 在 Linux 中降级 Flatpak 包
+
+**免责声明:** 与安装 Flatpak 不同,你需要 `sudo` 权限才能降级 Flatpak 包。如果你的用户没有该权限,你可以按照我们关于 [如何向用户授予 sudo 访问权限][2] 的详细指南进行操作。
+
+以下是步骤:
+
+#### 1、获取包的应用 ID
+
+第一步是找到要降级的包的应用 ID。你可以列出已安装的软件包轻松找到它:
+
+```
+flatpak list --app
+```
+
+![find flatpak package id in linux][4]
+
+记下要降级的包的应用 ID。
+
+这里,我要降级 Black Box,所以我的应用 ID 将是 `com.raggesilver.BlackBox`。
+
+#### 2、列出以前的版本并获取该提交的代码
+
+获得应用 ID 后,你需要列出以前的版本。
+
+你可以按照给定的命令语法做到这点:
+
+```
+flatpak remote-info --log flathub
+```
+
+![find previous releases in flatpak][5]
+
+找到首选的先前版本后,复制如上所示的提交的代码。
+
+#### 3、降级 Flatpack 包
+
+执行前两个步骤后,你应该有以下内容:
+
+- 包的应用 ID。
+- 首选旧版本的提交代码。
+
+现在,你必须将它们放在以下命令中:
+
+```
+sudo flatpak update --commit=
+```
+
+当我将 Black Box 降级到以前的版本时,我将使用以下命令:
+
+```
+sudo flatpak update --commit=c4ef3f4be655cbe2559451a9ef5977ab28139c54bb5adbd7db812f3482bd0db5 com.raggesilver.BlackBox
+```
+
+![downgrade flatpak package in linux][6]
+
+这就完成了!
+
+要检查你是否已成功降级软件包,你可以列出需要更新的软件包(考虑到其他所有内容都是最新的)。它应该包括你最近降级的软件包的名称:
+
+```
+flatpak update
+```
+
+![downgrade flatpak package][7]
+
+如你所见,Black Box 已过时,需要更新,这意味着包已成功降级!
+
+### 总结
+
+在本快速教程中,我解释了如何降级 Flatpak 软件包,希望对你有所帮助。
+
+如果你有任何疑问或建议,请在评论中告诉我。

+Linux QtFM 文件管理器的 3 个令人愉快的功能
+======
+
+![][0]
+
+> 这个 Linux 文件管理器做了你所期望的一切,没有留下不愉快的惊喜。但这里有一些令人惊喜的事情,使它值得一试。
+
+QtFM 是一个简单的文件管理器,旨在通过一个快速直观的界面提供文件管理的基本功能。它适用于 Linux、BSD 和 macOS。
+
+QtFM,顾名思义,使用 Qt(规范发音为 “cute”)编程工具包。我在 C++ 和 Python 中使用过 Qt 工具包,使用它总是一种乐趣。它是跨平台的,具有多个有用的抽象级别,因此开发人员不必直接与特定于供应商的 SDK 交互,而且它具有高度可配置性。从用户的角度来看,无论你使用的是最新的硬件还是[旧计算机][1],这都是一种“自然”且快速的体验。
+
+### 使用 QtFM
+
+QtFM 没有太多内容。它专注于实现其名称所声称的:Qt 的文件管理器(FM)。其布局可能是你对文件管理器的期望:左侧是常用位置和设备的列表,右侧是文件列表。
+
+![QtFM file manager][2]
+
+它只有四个菜单:
+
+- 文件:创建新文件或文件夹,打开新选项卡或窗口,或退出应用。
+- 编辑:在左侧面板中复制、粘贴、移至垃圾箱或创建新书签。
+- 视图:在列表视图和图标视图之间切换,调整布局。
+- 帮助:许可信息和在线文档链接。
+
+与 QtFM 交互与你可能习惯使用的任何标准文件管理器的体验大致相同。你可以点击导航、在其默认应用中打开文件、拖放文件和文件夹、复制和粘贴文件和文件夹、启动应用,以及你在与计算机内容交互时执行的任何其他操作。它很熟悉,所以基本上没有学习曲线,也没有不愉快的惊喜。
+
+然而,也有一些惊喜。这是我最喜欢的三个。
+
+### 1、将命令放入上下文菜单
+
+使用 QtFM,你可以将可以在终端中运行的任何命令添加到右键单击上下文菜单中。例如,假设你想要一个将图像转换为 [webp 格式][3] 的选项到右键菜单。无需学习复杂的框架或脚本语言,无需开发插件。你只需 3 个步骤即可完成:
+
+- 转到 “编辑” 菜单并选择 “设置”。
+- 单击 “自定义操作选项卡”。
+- 单击 “添加” 按钮并输入要运行的命令,用 `%f` 代表源文件,用 `%n` 代表新文件。
+
+![QtFM custom actions][4]
+
+该操作现在出现在你的 QtFM 上下文菜单中。
+
+### 2、灵活的布局
+
+Qt 工具包的内置功能之一是它的许多组件(“小部件”)是可分离的。QtFM 利用了这一点,并允许你从 “视图” 菜单中解锁其布局。解锁后,你可以拖动工具栏和侧面板,将它们固定在窗口周围的新位置。我能够将菜单栏、导航工具栏和 URI 字段组合到一个统一的面板中,并且为了方便,我在窗口的右侧放置了一个文件树。
+
+![QtFM unlocking the layout][5]
+
+这不需要应用设计甚至配置的特殊知识。你只需解锁、拖放和锁定。
+
+### 3、标签视图
+
+许多 Linux 文件管理器提供选项卡的方式与大多数 Web 浏览器相同。这是一个简单的界面技巧,可让你方便地保留多个位置。我不知道它是否真的节省了时间,但我总觉得它确实如此。QtFM 也提供选项卡,我特别喜欢它实现选项卡的方式有两点。
+
+首先,选项卡默认位于窗口底部(你可以在 “设置” 中更改它)。因为我倾向于从左到右、从上到下阅读,所以我通常更喜欢在窗口的底部和右端设置“额外”信息。当然,“额外”信息的构成因用户而异,因此我不会责怪任何开发人员将小部件和面板放置在我不会放置小部件和面板的地方。不过,当开发人员不小心同意我的偏好时,这很好。
+
+其次,标签是响应式的。只需将鼠标悬停在目标选项卡上,即可将文件或文件夹从一个选项卡拖动到另一个选项卡中。感觉就像从一个窗口拖放到另一个窗口一样自然。
+
+### 安装 QtFM
+
+在 Linux 上,你的发行版可能会将 QtFM 打包在它的软件仓库中。如果是这样,你可以使用包管理器进行安装。例如,在 Debian 和基于 Debian 的系统上:
+
+```
+$ sudo apt install qtfm
+```
+
+如果你的发行版不提供 QtFM,你可以在其 [网站][6] 上找到它的软件包,或者你可以从它的 [Git 仓库][7] 下载源码。

+Oh My Zsh 和 Powerlevel10k:天作之合
+======
+
+> 这是一篇快速而简单的指南,用 Oh My Zsh 和 Powerlevel10k 主题改造你的 Zsh 终端 Shell,使其在 Ubuntu 和其他 Linux 发行版中看起来很酷。
+
+![][1]
+
+大多数 Linux 发行版中的默认 Shell 是 Bash。Bash 是一个可靠的和传统的工具。然而,它缺乏一些自定义功能,比如漂亮的颜色、光标支持等等。
+
+你可以使用另一个 Shell,即 Zsh 来得到更多的设置调整,并帮助你扩展你的 Bash Shell 体验。
+
+这个简单的指南解释了如何安装 Zsh、Oh My Zsh 并应用 Powerlevel10k 主题。
+
+### Oh My Zsh 和 Powerlevel10k 安装和配置指南
+
+#### 1、安装 Zsh 和改变 Shell
+
+打开一个终端,使用以下适用于你的发行版的命令安装 Zsh。
+
+Ubuntu、Debian、Linux Mint 和所有相关的发行版:
+
+```
+sudo apt install zsh
+```
+
+Fedora:
+
+```
+sudo dnf install zsh
+```
+
+Arch:
+
+```
+pacman -S zsh
+```
+
+安装完成后,找出 Zsh 的安装路径:
+
+```
+whereis zsh
+```
+
+然后使用当前用户的 Zsh 可执行路径改变 Shell。
+
+```
+chsh -s /usr/bin/zsh <用户名 >
+```
+
+![改变当前用户的 Shell][2]
+
+关闭并再次打开终端。然后你应该看到 Zsh 的首次设置。选择选项 2。它将用一个默认的主题改变你的 Shell 提示符的外观,如下图所示:
+
+![Zsh 的首次设置][3]
+
+#### 2、安装 Oh My Zsh
+
+Oh My Zsh 是一套可以进一步定制 Zsh 的脚本。
+
+首先,我们将从 GitHub 上下载 Oh My Zsh 脚本来安装它。如果你有 `wget` 和 `git` 软件包,那就最好了。如果还没有安装,请使用以下命令 [安装 wget][4] & git:
+
+```
+sudo apt install wget
+sudo apt install git
+```
+
+然后用下面的命令安装 Oh My Zsh:
+
+```
+sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
+```
+
+然后你应该看到 Oh My Zsh 及默认主题 Robbyrussell 应用到了你的终端。
+
+![安装 Oh My Zsh 和默认主题][5]
+
+Oh My Zsh 还附带了其他的主题,你可以 [使用这篇指南][6] 安装它们。然而,在本教程中,我将谈论一个特定的主题,即 Powerlevel10k。
+
+#### 3、为 Oh My Zsh 安装 Powerlevel10k 主题
+
+打开终端,运行以下命令,从 GitHub 上克隆 Powerlevel10k 代码库,并将文件放到 Oh My Zsh 的配置文件夹中。
+
+```
+git clone https://github.com/romkatv/powerlevel10k.git $ZSH_CUSTOM/themes/powerlevel10k
+```
+
+用文本编辑器打开 `~/.zshrc` 文件,将 `ZSH_THEME` 变量设为 `"powerlevel10k/powerlevel10k"`。
+
+```
+cd ~
+```
+
+```
+nano .zshrc
+```
+
+默认情况下,它应该是 Robbyrussell。删除 `”robbyrussell"`,添加下面的 `"powerlevel10k/powerlevel10k"`。
+
+更改后,你的 `~/.zshrc` 文件应该是这样的:
+
+```
+ZSH_THEME="powerlevel10k/powerlevel10k”
+```
+
+保存并关闭该文件(`CTRL+O`、回车和 `CTRL+X`)。
+
+![改变 Oh My Zsh 主题为 Powerlevel10k][7]
+
+重新启动你的终端,启动首次向导来设置 Powerlevel10k 主题。
+
+#### 4、Powerleve10k 的首次设置
+
+安装后启动终端时,Powerlevel10k 会提示你各种问题以了解你的 Linux 发行版设置。所以,根据你的需要按下键,按照你的口味来定制你的终端。下面是一些问题的例子截图,可以给你一些启发。
+
+![Powerlevel10k - wizard1][8]
+
+![Powerlevel10k - wizard2][9]
+
+最后,你可以保存文件,享受你的终端的新面貌。
+
+![应用 Powerlevel10k Zsh 主题设置后][10]
+
+如果你想再次重启配置向导,运行以下程序。你可以随心所欲地做,次数不限。
+
+```
+p10k configure
+```
+
+基本设置就这样结束了。如果你想了解更多,请继续阅读。
+
+### 更多配置(高级用法)
+
+#### 5、安装 Dracula GNOME 终端主题
+
+如果你使用的是带有原生终端应用的 GNOME 桌面,你可以试试令人惊叹的 Drakula 主题。要做到这一点,打开一个终端,运行下面的命令来下载该主题:
+
+```
+git clone https://github.com/dracula/gnome-terminalcd gnome-terminal
+```
+
+打开 GNOME “终端”应用,进入偏好设置。通过点击 “+” 添加一个新的配置文件,并命名为 “drakula”。然后进入颜色标签,取消勾选 “使用系统主题的颜色” 选项。
+
+![为终端创建一个新的配置文件][11]
+
+回到终端,运行以下程序。当出现提示时,选择你刚才创建的配置文件名称,如上所述。
+
+```
+./install.sh
+```
+
+![为 GNOME “终端”应用 Drakula 主题][12]
+
+一旦安装完成,回到偏好设置中,将 Drakula 配置文件标记为默认。
+
+#### 6、Zsh 的自动补完和语法高亮
+
+你可能想试试由社区开发的两个可用于 Zsh 的插件。它们是 zsh-autosuggestions 和 zsh-syntax-highlighting。
+
+打开终端,运行以下程序,下载 zsh-autosuggestions,并将其放在插件文件夹中:
+
+```
+git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
+```
+
+同样地,为语法高亮插件运行以下程序:
+
+```
+git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
+```
+
+通过文本编辑器打开 `~/.zshrc`文件(使用以下命令),并找到 `plugins=(git)` 一行。并将其替换为以下内容:
+
+```
+nano ~/.zshrc
+```
+
+```
+plugins=(git zsh-autosuggestions zsh-syntax-highlighting)
+```
+
+使用 `CTRL+O`、回车和 `CTRL+X` 保存并关闭该文件。
+
+关闭并打开你的终端。现在,你应该可以使用自动建议和语法高亮了。
+
+### 总结
+
+这样就好了!你现在应该已经在你的系统上安装了 Oh My Zsh 和 Powerlevel10k 主题。你可以根据自己的需要,进一步定制 Powerlevel10k 主题的外观和行为。
+
+干杯。

+Home Assistant:谷歌助理、Alexa 和 Siri 的开源替代品
+======
+
+> 一个开源助手可以取代谷歌助理、Alexa 和 Siri?
+
+![An Open-Source Alternative to Google, Alexa, and Siri in Works for Home Assistant Platform][1]
+
+**Home Assistant** 是一个开源的智能家居平台,专注于为用户提供本地控制和隐私。它可以从树莓派或甚至本地服务器上运行。
+
+他们还有一个订阅服务,可以获得额外的功能,如支持 Alexa 和谷歌助理,它由一家名为 “[Nabu Casa][2]” 的公司管理。
+
+> 💡 该公司由 Home Assistant 的创始人 [Paulus Schoutsen][3] 领导。
+
+在上周的 [博客][4] 中,Paulus 宣布了**一个新的开源项目,旨在提供一个没有主动互联网连接的语音助手**,也无需任何其他大型科技公司的语音助手。
+
+这是 _一个对谷歌助理、Alexa 和 Siri 的开源挑战者?_ 😲
+
+让我们看看这到底是怎么回事。
+
+**它是什么?** 这将是 Home Assistant 应用的一部分,将提供在本地运行语音命令的能力,以控制连接的智能设备。
+
+Paulus 还断言,他们最重要的优先事项是支持不同的语言,他说:
+
+> 人们需要能够用自己的语言说话,因为对于智能家居的语音助手来说,这是最容易接受和唯一可以接受的语言。
+
+为了推动这一努力,Rhasspy 的创造者 [Mike Hansen][5] 已经被拉来实现这一目标。
+
+对于那些不知道的人来说,[Rhasspy][6] 是另一个开源软件,专门提供一个由其用户社区支持的完全离线的语音助手。
+
+如果你问我,我觉得 Home Assistant 的这个功能将由 Rhasspy 提供,这是一件好事。
+
+_为什么要重新发明已经存在的东西?最好是在它的基础上进行改进。_
+
+**可以期待什么?** 最初,这个语音助手做不到做你可能期待的事情。因此,像进行网络搜索、打电话、玩语音游戏等,都是不可能的。
+
+它所关注的反而是**语音助手应该有的基本功能**。这样做是为了确保他们面前的工作是可控的。
+
+他们的目标是从几个动作开始,然后围绕它们建立语言模型。
+
+在目前的状态下,Home Assistant 在其用户界面上支持 62 种不同的语言。他们计划用他们的语音助手增加对所有这些语言的支持。
+
+**何时期待?** 他们已经开始了这方面的工作,为每种语言建立一个 [意图匹配句子集合][7]。
+
+这意味着社区可以通过将智能设备的命令改编成各自的母语,来为语音助手的发展做出贡献。
+
+他们的目标是在 **2023** 年的某个时候发布,并提到这将是“_语音年_”。
+
+我认为一个可以离线工作的开源语音助手可以是一个非常有用的东西。它可以让你不受大科技公司的任何追踪。
+
+💬 _还有一个额外的好处是,它的开发背后有一个庞大的社区,有什么理由不喜欢呢?_

+
+不普通的普通操作系统:Vanilla OS 稳定版发布了!
+======
+
+> Vanilla OS 已经准备好让你尝试!在这里了解令人兴奋的地方。
+
+![][1]
+
+Vanilla OS 是一个基于 Ubuntu 的发行版,旨在为用户提供一个具有随需应变能力和自由选择软件包的 GNOME 体验。(LCTT 译注:Vanilla —— “香草”,因为作为太普通的香料,所以也有“普普通通”的意思。)
+
+经过几个月的测试,**Vanilla OS 的第一个版本** 终于以 **Vanilla 22.10 Kinetic** 的形式出现了,其提供了原汁原味的 **GNOME 43**。
+
+在最近的一次采访中,我们问创建者:“很多人认为我们已经有太多的发行版了。为什么还要有 Vanilla OS?”,**Mirko Brombin**,分享了一些有趣的见解享。请看下面我们与他的对话,探索关于 Vanilla OS 的令人兴奋的事情:
+
+> **[“不要害怕做出贡献”:Mirko Brombin 谈 Vanilla OS 和其他未来项目][22]**
+
+Vanilla OS 有几个特点,你可能会觉得有帮助,请允许我向你介绍一下。
+
+### 主要亮点
+
+![Vanilla OS 22.10 Kinetic][2]
+
+作为一个新的发行版,Vanilla OS 有一个装备精良的功能集,你可能会喜欢。一些值得注意的亮点包括:
+
+- 原生安装程序
+- Vanilla OS 首次设置 功能
+- Vanilla OS 控制中心
+- apx 软件包管理器
+- 随需应变能力
+
+#### 原生安装程序
+
+![Vanilla OS 安装程序][3]
+
+Vanilla OS 有一个用 [GTK4][4] 和 [libadwaita][5] 编写的原生的安装程序,它取代了该操作系统在早期开发阶段时使用的 [Calamares][6] 安装程序。
+
+![Vanilla OS 安装程序正在进行][7]
+
+之前,他们还宣布将使用来自 Crystal Linux 团队的 [Jade][8] 安装程序。
+
+但是,他们改变了主意,选择在现有的 [Vanilla 首次设置][10] 项目之上建立 [Vanilla 安装程序][9]。
+
+#### Vanilla OS 首次设置
+
+![Vanilla OS 首次设置][11]
+
+Vanilla OS 的安装完成后,你会看到一个快速设置屏幕,上面用各种语言写着 “欢迎”。
+
+![Vanilla OS 软件包管理器选择][12]
+
+然后它将带你完成各种设置,如选择颜色方案,选择你想要的软件包管理器,是否要安装受限制的编解码器,等等。
+
+我必须说,这很方便! 😃️
+
+#### Vanilla OS 控制中心
+
+![Vanilla OS 控制中心][13]
+
+这个图形化工具使你能够对操作系统进行修改,如运行关键更新和安装额外的驱动程序。
+
+#### 随需应变的不变性
+
+![展示 - Vanilla OS 中的 ABRoot 事务性更新][14]
+
+正如上面 Vanilla OS 的创始人所展示的,这个操作系统可以提供完全的不变性和原子性,允许你在两个根分区(A/B)之间进行交易。
+
+你问这是什么意思? 🤔
+
+嗯,这意味着你的系统的核心部分被锁定,以防止任何不必要的变化,特别是那些由损坏的应用程序或错误的更新引起的变化。
+
+Vanilla OS 使用 [ABRoot][15] 来实现这一目标,之前,他们曾尝试使用 [Almost][16],但结果并不理想。
+
+![][17]
+
+它还有一个**智能更新功能**,他们解释如下:
+
+> VSO(Vanilla System Operator)是一个工具,它将定期检查更新,然后如果设备没有处于大量使用状态,就在后台下载和安装。事实上,VSO 检查是否满足某些检查条件,如资源是否空闲(CPU/RAM),连接是否允许,电池是否至少有 30% 的电量等。
+
+更新是通过 ABroot 应用的,并在下一次重启时得到修补,而不需要花费额外时间。
+
+#### apx 软件包管理器
+
+![Vanilla OS apx][18]
+
+Vanilla OS 带有 [apx][19] 工具,允许你在不修改根文件系统的情况下在管理的容器内安装软件包。
+
+### 下载 Vanilla OS
+
+如果你认为 Vanilla OS 解决了你在 Ubuntu 上遇到的问题,并且想要一个原汁原味的 GNOME 体验,那就来试试吧。
+
+你可以在其 [官方博客文章][20] 中了解更多关于 Vanilla OS 22.10 的信息。

+在使用 Rust 时,失败的函数会返回 [Result][3] 类型。尤其是文件系统模块会返回专门的类型 [std::io::Result][4]。有了这些知识,你可以从 `main()` 函数中返回相同的类型:
+
+```
+fn main() -> std::io::Result<()> {
+/* ...code comes here... */
+```
+
+### Rust 文件写入
+
+在 Rust 中执行文件的 I/O 操作是相对容易的。写入文件可以简化为一行:
+
+```
+use std::fs;
+fs::write("favorite_websites.txt", b"opensource.com")?;
+Ok(())
+```
+
+使用错误传播操作符 `(?)`,错误信息被传递到调用函数中,随后可以处理错误。由于 `main()` 是调用栈中唯一的其他函数,如果写操作失败,错误信息将被传递到控制台输出。
+
+[fs::write][5] 函数的语法是非常先进的。第一个参数是文件路径,它必须是 [std::path::Path][6] 类型。第二个参数是内容,它实际上是一个字节切片(`[u8]`)。Rust 将传递的参数转换为正确的类型。幸运的是,这些类型基本上是下面的例子中所处理的唯一类型。
+
+使用文件描述符类型 [std::fs::File][7] 可以实现对写操作更简洁的访问:
+
+```
+let mut file = fs::File::create("favorite_websites.txt")?;
+file.write_all(b"opensource.com\n")?;
+Ok(())
+```
+
+由于文件类型实现了 [Write][8] 特性,所以可以使用相关的方法来写入文件。然而,`create` 方法可以覆盖一个已经存在的文件。
+
+为了获得对文件描述符的更多控制,必须使用 [std::fs::OpenOptions][9] 类型。这提供了类似于其他语言中的打开模式:
+
+```
+let mut file = fs::OpenOptions::new()
+ .append(true)
+ .open("favorite_websites.txt")?;
+
+file.write_all(b"sourceforge.net\n")?;
+```
+
+### Rust 文件读取
+
+适用于写的东西也适用于读。读取也可以通过简单的一行代码来完成:
+
+```
+let websites = fs::read_to_string("favorite_websites.txt")?;
+```
+
+以上一行读取文件的内容并返回一个字符串。除了读取字符串,还有 [std::fs::read][10] 函数,如果文件包含二进制数据,该函数会将数据读成一个字节向量。
+
+下一个例子显示了如何将文件的内容读入内存,随后逐行打印到控制台:
+
+```
+let file = fs::File::open("favorite_websites.txt")?;
+let lines = io::BufReader::new(file).lines();
+
+for line in lines {
+ if let Ok(_line) = line {
+ println!(">>> {}", _line);
+ }
+}
+```
+
+### 总结
+
+如果你已经熟悉了其他编程语言,你可能已经注意到没有 `close-` 函数(或类似的)来释放文件句柄。在 Rust 中,当相关变量超出作用域,文件句柄就会被释放。为了定义关闭行为,可以在文件表示的周围应用作用域 `({ })`。我建议你熟悉 [Read][11] 和 [Write][8] 特性,因为你可以在许多其他类型中找到这个特性的实现。

+who 命令的解释与示例
+======
+
+![][0]
+
+> 这里是一个关于理解 Linux 中 who 命令的初学者指南,并带有几个例子。
+
+这篇文章是 [Linux 命令][1]学习系列的一部分。
+
+### who 命令
+
+Linux 中的 `who` 命令用于显示当前登录到系统中的用户的信息。它显示用户的登录名,用户登录的终端,用户登录的时间,以及远程主机名(如果有)。
+
+#### 语法
+
+下面是 `who` 命令的基本语法:
+
+```
+who [OPTION]... [ FILE | ARG1 ARG2 ]
+```
+
+### 各种 who 命令和开关的例子
+
+默认情况下,`who` 读取文件 `/var/run/utmp`,其中包含当前登录的用户的信息。如果没有指定选项,它会显示每个用户的登录名、终端和登录时间。
+
+```
+who
+```
+
+它给出了以下输出。你可以看到它显示了登录名是 `debugpoint`,终端 ID `tty2` 和登录的日期和时间。
+
+```
+debugpoint tty2 2023-01-01 11:22 (tty2)
+```
+
+![who 命令 - 默认示例][2]
+
+然而,如果你在虚拟机中运行上述命令,你应该看到同样的情况,但终端 ID 将是 x11 服务器的显示名称,即 `:0`。
+
+```
+❯ who
+debugpoint :0 2023-01-01 23:36 (:0)
+```
+
+要显示当前用户的用户名和信息,使用下面的方法:
+
+```
+whoami
+```
+
+使用 `-b` 选项查看最后一次系统启动时间:
+
+```
+❯ who -b
+system boot 2023-01-01 23:36
+```
+
+显示当前系统中登录的用户数:
+
+```
+❯ who -q
+debugpoint
+users=1
+```
+
+所有上述命令与 `-H` 选项配对时,你会有一个更好的含标题行的信息,如下所示:
+
+```
+who -H
+
+NAME LINE TIME COMMENT
+debugpoint tty2 2023-01-01 11:22 (tty2)
+```
+
+如果你想在 Linux 中显示与 `who` 命令有关的所有信息,请使用选项 `-a`:
+
+```
+who -aH
+
+NAME LINE TIME IDLE PID COMMENT EXIT
+system boot 2023-01-01 11:19
+run-level 5 2023-01-01 11:19
+debugpoint + tty2 2023-01-01 11:22 13:26 2042 (tty2)
+```
+
+像往常一样,你可以使用下面的重定向将 `who` 命令的输出保存到任何文件:
+
+```
+who > user_details.txt
+```
+
+#### who 命令选项的例子总结
+
+下面是一些 `who` 命令的例子和它们的解释:
+
+下面是一些可以与 `who` 命令一起使用的选项:
+
+- `-a`: 显示每个用户的主机名、登录时间和进程
+- `-b`: 显示上次系统启动的时间
+- `-d`: 显示死进程(已终止但未从 utmp 文件中删除的进程)
+- `-H`: 显示标题行
+- `-l`: 显示长格式的登录进程
+- `-m`: 只显示在 `ARG1 ARG2` 指定的终端上登录的用户的名字和行。
+- `-q`: 显示已登录用户的数量
+- `-u`: 显示拥有未脱离进程的用户的信息
+- `-w`: 显示已经登录的用户信息,格式与 utmp 文件相同
+
+### 总结
+
+我希望这篇文章能够帮助你了解 `who` 命令及其基本原理。你也可以阅读 [who 手册页][3]来了解更多。如果你有任何问题,请告诉我。

+Ultramarine Linux 37 版本发布
+======
+
+![][1]
+
+> Ultramarine Linux 的新版本来了。Ultramarine Linux 37 带有新的自定义软件仓库、KDE Plasma 特色版等等。
+
+如果你不知道,Ultramarine Linux 是一个基于 Fedora 的发行版,提供了 Budgie、Pantheon、GNOME 等桌面环境。这个发行版通过这些令人赞叹的桌面环境给你提供了最好的 Fedora 体验。
+
+最近,这个小项目被 [FyraLabs][2] 收购,后者是 PhotonBrowser 和 tauOS 背后的公司。而这使得 Ultramarine 项目有了必要的人力和资金来继续建设他们的发行版。
+
+自 Fedora 37 发布以来,该团队一直致力于重件当前版本,这包括采用新的基础设施和 CI/CD 管道迁移。终于,Ultramarine Linux 37 登场了。
+
+那么,它有什么新东西呢?
+
+### Ultramarine Linux 37 的新功能
+
+自从被 Fyralabs 收购后,该团队升级并迁移到用于自动化 CI/CD 构建的 GitHub Actions。Ultramarine 自己的软件仓库用于分发其精心组织的软件包(例如 Pantheon 桌面),它在这个版本中会发生变化,并转移到 FyraLabs 的基础设施上。
+
+因此,如果你正在运行 Ultramarine 36 版本,它可能无法正常工作。你最好重新安装这个版本,因为显然没有从 36 版到 37 版的升级路径。
+
+此外,Ultramarine 37 为 Fedora 软件包引入了一个名为 [Terra][3] 的滚动仓库,其中包括数百个 Fedora 不提供的应用程序。你可以认为它类似于 [RPM Fusion][4],尽管有所不同。
+
+要了解更多,请访问 [本页][3] 或从命令行添加以下软件仓库:
+
+```
+sudo dnf config-manager --add-repo https://terra.fyralabs.com/terra.repo
+```
+
+事实上,这开启了一种可能性,因为你也可以尝试在 Fedora Linux 中谨慎地使用它。如果上述软件仓库能在普通的 Fedora 安装中开箱即用,那就更棒了。
+
+在上述变化的基础上,Ultramarine Linux 37 首次引入了 KDE Plasma 作为官方版本。KDE Plasma 特色版带来了含有 Latte Dock 和 Lightly Qt 主题的 Pop OS 风格外观。
+
+![Ultramarine Linux 37 具有独特的 Pop OS 风格的 KDE Plasma 主题][5]
+
+Ultramarine Linux 37 也放弃了 Cutefish 桌面,因为它目前正处于 [混乱的开发状态,没有可见的路线图][6]。这是该团队的一个很好的决定,因为打包一个已经停止的项目是没有意义的。
+
+Budgie 桌面旗舰版使用上游的 Fedora 软件包,有更多的默认应用程序。最近,Fedora Linux 删除了对 elementary OS 的 Pantheon 桌面的支持,很遗憾。感谢 Ultramarine Linux 开发者,你仍然可以体验它,因为它已经被转移到新的 Terra 软件仓库中。
+
+你应该庆幸,Ultramarine Linux 是唯一一个的基于 Fedora 的支持令人赞叹的 Pantheon 桌面的发行版。
+
+最后,Ultramarine Linux 37 的核心基于 [Fedora 37][7],采用 Linux 主线内核 6.0。因此,所有更新的软件包和工具链都在这个版本中。
+
+所以,这就是关于这个版本的总结。请继续关注几天后对这个版本的官方点评。如果有兴趣,你可以在这里阅读之前的版本(36)的评论。

+> **[Ultramarine Linux:带有 Budgie、Cutefish 和 Pantheon 桌面的终极 Fedora 特色版][8]**
+
+### 下载和升级
+
+由于没有升级路径,建议你对该版本进行全新安装。你可以在下面下载各个桌面环境的 ISO 文件。

+whereis 命令的解释与示例
+======
+
+> 这是一份关于如何理解 Linux 和 BSD 中 `whereis` 命令的初学者指南,还包括几个例子。
+
+![][1]
+
+这篇文章是 [Linux 命令][2] 学习系列的一部分。
+
+### whereis 命令
+
+`whereis` 命令是一个命令行程序,可以帮助你找出任何二进制可执行文件、源文件或手册页的路径或位置。
+
+在告诉你如何使用 `whereis` 命令之前,让我们先看看其语法。
+
+### 语法
+
+以下是 whereis 命令的语法:
+
+```
+whereis [OPTIONS] FILE_NAME
+```
+
+`whereis` 命令的参数是你要搜索的程序名或文件名。该参数是必须的。
+
+默认情况下,它在环境变量(如 `HOME`、`USER`、`SHELL` 等)中定义的路径中搜索程序。
+
+让我们看下一些例子。
+
+### Linux 和 BSD 中 whereis 命令的例子
+
+下面是 `whereis` 命令的一个简单例子,我试图搜索 `firefox`。在下面的输出中,你可以看到包含 `firefox` 文件或可执行文件的路径列表。
+
+```
+$ whereis firefox
+
+firefox: /usr/bin/firefox /usr/lib64/firefox /etc/firefox /usr/share/man/man1/firefox.1.gz
+```
+
+![Linux 中 whereis 命令的简单例子][3]
+
+带有选项 `-l` 的命令会显示其搜索的路径列表。比如:
+
+```
+$ whereis -l
+
+bin: /usr/bin
+bin: /usr/sbin
+bin: /usr/lib
+bin: /usr/lib64
+bin: /etc
+bin: /usr/games
+bin: /usr/local/bin
+bin: /usr/local/sbin
+bin: /usr/local/etc
+bin: /usr/local/lib
+bin: /usr/local/games
+```
+
+如果 `whereis` 命令没有找到任何东西,它只显示参数的名称。例如,如果我在 Linux 中搜索 `nano`,它没有安装,它的输出如下:
+
+```
+$ whereis nano
+```
+
+```
+nano:
+```
+
+如果你想搜索更多的参数,你可以随时添加多个参数。例如,下面的命令同时搜索 `bash` 和 `nano`,输出结果是这样的:
+
+```
+$ whereis bash nano
+
+bash: /usr/bin/bash /usr/share/man/man1/bash.1.gz /usr/share/info/bash.info.gz
+nano: /usr/bin/nano /usr/share/nano /usr/share/man/man1/nano.1.gz /usr/share/info/nano.info.gz
+```
+
+你也可以使用 `-b` 选项搜索特定的文件类型,比如二进制文件。下面的命令只告诉你 `nano` 的二进制路径。
+
+```
+$ whereis -b nano
+
+nano: /usr/bin/nano /usr/share/nano
+```
+
+同样,`-s` 选项可以搜索源文件,而 `-m` 选项可以搜索手册页。
+
+```
+$ whereis -m nano
+
+nano: /usr/share/man/man1/nano.1.gz /usr/share/info/nano.info.gz
+```
+
+你也可以结合上面的选项来进行更广泛的搜索。例如,下面的命令可以搜索 `nano` 和 `firefox` 的二进制、手册页;而对于 `bash`,只搜索手册页。
+
+```
+$ whereis -bm nano firefox -m bash
+
+nano: /usr/bin/nano /usr/share/nano /usr/share/man/man1/nano.1.gz /usr/share/info/nano.info.gz
+firefox-m:
+bash: /usr/bin/bash /usr/share/man/man1/bash.1.gz /usr/share/info/bash.info.gz
+```
+
+下面是选项的摘要:
+
+| 选项 | 描述 |
+| :- | :- |
+| `-b` | 只搜索二进制文件。|
+| `-m` | 只搜索手册页部分。|
+| `-s` | 只搜索源码。|
+| `-u` | 搜索不寻常的条目。如果一个文件没有所要求的每种类型的条目,就被称为不寻常。因此,`whereis -m -u *` 会查询当前目录中没有文档的那些文件。|
+| `-B` | 改变或限制 `whereis` 搜索二进制文件的地方。|
+| `-M` | 更改或限制 `whereis` 搜索手册的位置。|
+| `-S` | 更改或以其他方式限制 `whereis` 搜索源码的位置。|
+| `-f` | 终止上一个目录列表并指示文件名的开始,并且必须在使用任何 `-B`、`-M` 或 `-S` 选项时使用。|
+
+### 总结
+
+我希望这篇文章能够帮助你理解 `whereis` 命令及其基本原理。你也可以阅读 [whereis 手册页][4] 来了解更多。如果你有任何问题,请告诉我。

+Fedora 38 将发布 Budgie 和 Sway 官方定制版
+======
+
+> 两款新的 Fedora 定制版将在 Fedora 38 发布时首次亮相。
+
+![][1]
+
+我们期待着它们在 Fedora 37 时出现,但在 Fedora 38 中终于来了!
+
+早在 2022 年 5 月,Budgie 项目的主要开发者 Joshua Strobl [宣布][2],Budgie 已被提交到 Fedora 中。
+
+遗憾的是,在那之后不久,我们并没有看到任何官方 [Fedora 定制版][3] 发布的迹象,尽管它在 [Fedora 37 发布][4] 期间进入了 Fedora 软件库。
+
+**但现在有了。**
+
+随着 Fedora 38 的发布,看起来我们会得到一个 [Budgie][5] 的官方定制版,同时还有一个 [Sway][6] 窗口管理器的定制版。
+
+### Fedora Budgie 和 Sway
+
+在 [最近的一次会议][9] 上,Fedora 工程和指导委员会(FESCo)投票决定将 Budgie 和 Sway 窗口管理器的 Fedora 官方定制版纳入 Fedora 38 的发布中。
+
+根据 Budgie 和 Sway 的初步修改建议,我们可以期待很多变化。
+
+对于 Budgie:
+
+- Fedora 38 将提供 Budgie 桌面环境,包含一套核心应用程序,如用于更新/软件包管理的 GNOME “软件”应用、一个文本编辑器、一个网页浏览器和一个终端。
+- 它还将使用 [Materia GTK][10] 和 [Papirus][11] 图标主题,整个系统采用 GTK 主题设计。
+- Budgie 定制版还将采用 lightdm + slick-gtk-greeter,以获得更直观的用户问候体验。
+
+对于 Sway 定制版:它旨在提供一个极简体验,只包括默认配置之上的一些元素。
+
+预期时间:随着 Fedora 38 的开发在未来几个月内的加快,你可以期待这些定制版在 2023 年 4 月期间出现。当然,会有预装了 Budgie 和 Sway 的单独 ISO 文件。
+
+因此,我认为看到 Budgie 与 Fedora 的体验会非常吸引人,特别是当 Budgie 的开发似乎正在发生一些有趣的变化。

+Nitrux 2.6.0 大胆抛弃 apt
+======
+
+![][1]
+
+> Nitrux 2.6.0 带有 Flathub、默认支持的 Pipewire、最新内核和 KDE 框架。
+
+![Nitrux 2.6.0 Desktop][2]
+
+[Nitrux Linux][3] 是基于 Debian 的,它带有一个名为 NX 桌面的修改版的 KDE Plasma 桌面。这个独特的 Linux 发行版带来了一套自己的建立在 Maui kit 和 Qt 之上的 Nitrux 应用程序。Nitrux 是无 systemd 的,使用 OpenRC 作为启动系统。所有这些独特的功能和令人惊叹的外观,使它成为当今最好的 Linux 发行版之一。
+
+Nitrux 2.6.0 被提升为一个主要版本,因为它对 12 月发布的 2.5.1 版本进行了关键的更新。
+
+### Nitrux 2.6.0 的新内容
+
+这个版本的一个主要重点是在 SDDM 显示管理器中引入 Plasma Wayland 会话。Wayland 还不是默认的,但可以作为选项选择。X11 仍然是默认的。我相信在下一个主要版本中 NItrux 团队可以默认启用 Wayland。
+
+此外,现代声音管理器 Pipewire 现在是默认的,因为它已经在 Ubuntu 和 Fedora 中标准化了,而且感觉很稳定。由于有了 Pipewire,你的音频工作流程将变得更好。
+
+Nitrux 2.6.0 还默认启用了最大的 Flatpak 应用程序仓库 - Flathub。这意味着你不需要再手动设置 Flatpak 和启用 Flathub。现在,Flatpak 应用程序的安装变得更加容易。
+
+其他值得注意的变化包括:Nitrux 使根(/)分区成为不可变分区,以防止它被破坏,Samba 包现在是 Nitrux 默认安装的一部分,Calamares 安装程序有了一个定制的自动分区方案。
+
+![Nitrux 2.6 安装自动分区][4]
+
+从一开始,Nitrux 就倾向于为其整个桌面组件提供自包含的可执行文件。主要的选择是 AppImage 文件格式。在这个版本中,你会得到默认的 Flathub 环境,而流行的 apt 软件包管理器现在被放弃了。这可能会改变一些用户的工作流程,因为 `apt` 命令将无法工作;尽管它是基于 Debian 的。
+
+因此,Nitrux 团队建议使用 Distrobox 容器来设置单独的环境,以便与 apt 一起使用。然而,对于普通用户来说,理解容器、不可变的根分区会有点困难。
+
+![apt 被放弃][5]
+
+讽刺的是 `apt` 会在安装时使用,因为 Calamares 需要它。然而,在安装完成后,它会被删除。
+
+> 现场 ISO 中包括 APT 和 dpkg,但这是因为 Calamares 需要它们来完成安装,并将从安装的系统中删除。
+>
+> —— NITRUX TEAM
+
+Nitrux 2.6.0 的核心是 liqurix 内核 6.1,以及游戏和多媒体功能。这个版本由 KDE Plasma 2.26.4、KDE Framework 5.101.0 和 Qt 5.15.7 LTS 驱动。
+
+如果你想阅读更多信息,可以在 [这里][6] 找到详细的发布说明。
+
+### 下载
+
+你可以从以下页面下载这个版本。然而,没有可用的升级路径。因此,建议进行新的安装。
+
+- [FOSS Torrents(Torrent)][7]
+- [Sourceforge(镜像)][8]
+- [OSDN(镜像)][9]

+
+Budgie 10.7 即将带来 3 项关键改进
+======
+
+> Budgie 10.7 有很多有价值的改进。请看本文。
+
+![][1]
+
+Budgie 是一个旨在将杂乱无章降到最低,为用户提供一个干净/简约的体验的桌面环境。
+
+早在 2022 年 1 月,Solus 的前联合负责人 Joshua Strobl [离开了 Solus][2],从事 [SerpentOS][3] 的开发,但他还继续参与 Budgie 的开发。
+
+因此,他将该项目复刻到一个新的代码仓库,并成立了 [Buddies Of Budgie][4] 组织。三个月后,他们发布了 **Budgie 10.6**。
+
+这是一个很不错的版本,即使不是很特别。
+
+展望未来,他们发布了 2023 年的计划,其中包括发布 **Budgie 10.7**。
+
+[Joshua Strobl][5] 在博文中也提到了更多计划内容:
+
+> 至少,它应该是一个很好的基础,并为 Budgie 桌面今年的发展方向提供一个清晰的蓝图:Budgie 10.x 将会增加新的功能、QoL 改进和修复。Budgie 11 的开发工作也将起步。
+
+### Budgie 10.7 可以期待什么?
+
+Budgie 10.7 的开发工作自去年以来一直在进行。它本应在 2022 年发布,但需要更多的时间来提供一个完美的体验。
+
+已经完成了很多工作,但其中一些值得注意的三个变化是:
+
+- 对 Budgie 菜单的更新
+- 新的 Budgie 屏幕截图工具
+- 对 Budgie 运行对话框的改进
+
+#### 对 Budgie 菜单的更新
+
+![Budgie 10.7 菜单][6]
+
+在这个版本中,Budgie 菜单将得到一些改进,例如。
+
+- 一个新的电源菜单,包含所有常用的选项,如**暂停、休眠、注销和关闭电源**。
+- 更新的个人用户菜单可以快速访问 XDG 目录。这将让你直接打开文件管理器窗口进入主页、文档、音乐等文件夹。
+- 快速访问 Budgie 控制中心和桌面设置。
+- 能够从菜单本身显示各种桌面设置。
+
+#### Budgie 屏幕截图工具
+
+![Budgie 10.7 屏幕截图工具][7]
+
+终于,你不再需要下载另一个工具来在 Budgie 上进行截图;从 10.7 开始,它将具有一个原生的屏幕截图应用程序。
+
+它将支持对屏幕、窗口的捕捉,甚至是进行选区捕捉。
+
+#### 对 Budgie 运行对话框的改进
+
+![Budgie 10.7 运行对话框][8]
+
+Budgie 运行对话框将获得许多改进,例如:
+
+- 一个新的应用程序索引器将被用于 Budgie 菜单,以寻找和分类应用程序。它应该能提供一个 “可预测的模糊搜索体验”。
+- 根据显示器的工作区域改进对话框的大小计算。
+- 更好的应用程序名称和描述的标签样式。
+
+### 发布和未来计划
+
+根据他们的 [公告][9],他们打算在 2023 年第一季度的某个时候发布 Budgie 10.7。他们还没有确定一个具体的日期。
+
+并计划在不久之后发布带有错误修复的 10.7.1 版本,然后在 2023 年第二季度发布 Budgie 10.8。

+
+w 命令的解释与示例
+======
+
+> 下面是一份关于理解 Linux 和 BSD 中的 w 命令的初学者指南,并附有几个例子。
+
+![][0]
+
+这篇文章是 [Linux 命令][2]学习系列的一部分。
+
+### w 命令
+
+`w` 命令是 Linux 中的一个工具,它显示当前登录到系统中的用户及其进程的信息。它显示谁已登录,以及他们正在做什么活动。这意味着它可以显示他们在系统中运行什么进程。
+
+### 语法
+
+下面是 `w` 命令的基本语法:
+
+```
+w [options] [username]
+```
+
+`w` 命令接受一个可选的选项列表,然后是一个可选的用户名。如果指定了用户名,`w` 将只显示该用户拥有的进程信息。
+
+### w 命令的例子及其用法
+
+下面是一些使用 `w` 命令的例子。
+
+当你只用 `w` 运行它时,它显示以下输出:
+
+```
+$ w
+ 21:45:07 up 1 day, 12:48, 1 user, load average: 1.05, 0.85, 0.56
+USER TTY LOGIN@ IDLE JCPU PCPU WHAT
+debugpoi tty2 Thu08 36:48m 0.03s 0.03s /usr/libexec/gnome-session-binary
+```
+
+![Linux 中 w 命令的基本输出][3]
+
+解释:`USER` 列给出了用户名,然后是终端号、登录日期时间、空闲时间、CPU 使用率,以及用户正在执行的进程。
+
+- `USER` - 在你的 Linux 或 BSD 系统中登录的用户名称。
+- `TTY` - 当前会话的终端标识符号。
+- `FROM` - 用户的主机名或 IP 地址。
+- `LOGIN@` - 用户登录的时间。它有时会根据你的系统设置显示日期。
+- `IDLE` - 用户与终端交互后的空闲时间。
+- `JCPU` - 该会话的所有用户进程使用的 CPU 时间。
+- `PCPU` - 该用户的进程(在 `WHAT` 字段中提到)使用的时间。
+- `WHAT` - 当前带参数的进程。
+
+下面是 `w` 命令的另一个例子,有两个用户在虚拟机环境中登录。正如你所看到的,显示了两个用户名与当前运行的带有进程参数的独立进程。
+
+![演示多用户环境的 w 命令输出][4]
+
+让我们看一下这个命令的一些选项。
+
+要停止显示标题,使用 `-h` 选项。它与 `--no-header` 开关相同。
+
+```
+$ w -h
+```
+
+`-f` 选项可以在输出中切换 `FROM` 字段的可见性。
+
+```
+$ w -f
+```
+
+使用 `-s` 选项打印一个简短的输出,不包括 `JCPU`、`PCPU` 和 `LOGIN@` 信息。
+
+```
+$ w -s
+```
+
+要显示一个特定用户(例如,`debugpoint`)拥有的所有进程的列表:
+
+```
+$ w debugpoint
+```
+
+### 结束语
+
+我希望这篇文章能帮助你了解 `w` 命令及其基本原理。你也可以阅读 [w 手册页][5] 来了解更多。如果你有任何问题,请告诉我。

+
+通过编写“猜数字”游戏来学习 Ada 编程语言
+======
+
+![][0]
+
+> 这个 "猜数字 "游戏是学习新编程语言的一个很好的入门程序,因为它以一种相当直接的方式锻炼了几个常见的编程概念。
+
+当你想 [学习一种新的编程语言][1] 时,把注意力放在编程语言的共同点上是很好的:
+
+- 变量
+- 表达式
+- 语句
+
+这些概念是大多数编程语言的基础。一旦你理解了它们,你就可以开始琢磨其他的东西了。因为编程语言通常有相似之处,一旦你知道一种语言,你就可以通过了解其差异来学习另一种语言的基础知识。
+
+学习新语言的一个好方法是用一个标准程序进行练习。这使你能够专注于语言,而不是程序的逻辑。在这个系列文章中,我使用了一个“猜数字”的程序,在这个程序中,计算机在 1 到 100 之间挑选一个数字,并要求你猜出来。程序循环进行,直到你猜对数字为止。
+
+这个程序锻炼了编程语言中的几个概念:
+
+- 变量
+- 输入
+- 输出
+- 条件判断
+- 循环
+
+这是一个学习新的编程语言的很好的实践实验。
+
+### 安装 Ada
+
+[Ada 编程语言][2] 是一种独特的、高度结构化的语言,有专门一群开发者使用它。Ada 的工具链是 GNU Ada 开发环境,多被称为 GNAT。
+
+你可以使用你的发行版的包管理器在 Linux 上安装 GNAT。在 Fedora、CentOS 或类似系统上:
+
+```
+$ sudo dnf install gcc-gnat
+```
+
+在 Debian、Linux Mint 及衍生版上:
+
+```
+$ sudo apt install gnat
+```
+
+在 macOS 和 Windows 上,你可以从 [Adacore 网站][3] 下载一个安装程序(从下拉菜单中选择你的平台)。
+
+### 在 Ada 中猜数字
+
+创建一个名为 `game.adb` 的文件。
+
+这个程序使用的两个内置 Ada 库:`Text_IO` 和 `Numerics.Discrete_Random`:
+
+```
+with Ada.Text_IO;
+use Ada.Text_IO;
+with Ada.Numerics.Discrete_Random;
+```
+
+#### 过程头
+
+过程 的名称必须与文件的名称一致。第一部分是定义变量。
+
+注意,`discrete_random` 是专门针对特定范围的。在这里,允许数字范围:
+
+```
+procedure Game is
+ type randRange is range 1..100;
+ package Rand_Int is new ada.numerics.discrete_random(randRange);
+ use Rand_Int;
+ gen : Generator;
+ num : randRange;
+ incorrect: Boolean := True;
+ guess: randRange;
+```
+
+#### 过程逻辑
+
+该逻辑从 `reset(gen)` 开始。这将初始化随机数发生器,确保每次运行程序时,用 `random(gen)` 初始化的数字将是不同的。
+
+下一步是运行循环:
+
+- 输出猜测的指令
+- 读取该行
+- 将其转换为 `randRange`。
+- 将其与数字进行核对
+
+如果数字匹配,`incorrect` 被设置为 `False`,导致循环的下一次迭代退出。
+
+最后,程序在退出前会打印出对猜测正确性的确认:
+
+```
+begin
+ reset(gen);
+ num := random(gen);
+ while incorrect loop
+ Put_Line ("Guess a number between 1 and 100");
+ declare
+ guess_str : String := Get_Line (Current_Input);
+ begin
+ guess := randRange'Value (guess_str);
+ end;
+ if guess < num then
+ Put_line("Too low");
+ elsif guess > num then
+ Put_line("Too high");
+ else
+ incorrect := False;
+ end if;
+ end loop;
+ Put_line("That's right");
+end Game;
+```
+
+### 编译程序
+
+编译 Ada 程序的最简单方法是使用 `gnatmake`:
+
+```
+$ gnatmake game.adb
+aarch64-linux-gnu-gcc-10 -c game.adb
+aarch64-linux-gnu-gnatbind-10 -x game.ali
+aarch64-linux-gnu-gnatlink-10 game.ali
+```
+
+这将生成一个名为 `game` 的二进制文件。
+
+### 运行程序
+
+程序的每次运行都会有一些不同。这是一个例子:
+
+```
+$ ./game
+Guess a number between 1 and 100
+50
+Too low
+Guess a number between 1 and 100
+75
+Too low
+Guess a number between 1 and 100
+82
+Too low
+Guess a number between 1 and 100
+90
+Too high
+Guess a number between 1 and 100
+87
+Too low
+Guess a number between 1 and 100
+88
+That's right
+```
+
+### 学习 Ada
+
+这个“猜数字”游戏是学习新的编程语言的一个很好的入门程序,因为它以一种相当直接的方式锻炼了几个常见的编程概念。通过在不同的编程语言中实现这个简单的游戏,你可以展示这些语言的一些核心概念,并比较它们的细节。
+
+你有喜欢的编程语言吗?你会如何用它来写“猜数字”的游戏?请关注本系列文章,看看你可能感兴趣的其他编程语言的例子吧!

+OBS Studio 29 发布,但对 Linux 用户来说变化不大
+======
+
+> OBS Studio 29 是一个令人兴奋的版本,在所有平台上都有关键的改进。
+
+![][1]
+
+[OBS Studio][2] 是最受欢迎的开源屏幕录制和流媒体软件之一。
+
+许多 Linux 用户和内容创作者都在使用它,它有一套相当不错的工具和功能,可以让你录制和串流内容。
+
+它的上一个主要版本发布于 2022 年 9 月,它带来了对苹果芯片的原生支持、更新了用户界面、改进了颜色支持等等。
+
+它的下一个版本,即 v29,似乎有点意思,但对 Linux 用户来说变化不大 😞
+
+### OBS Studio 29 的新变化
+
+![OBS Studio 29][3]
+
+这个版本有大量的改进和修复;其中一些亮点包括:
+
+- 对 Linux 的媒体键支持
+- 新的音频过滤器
+- 改进的英伟达视频和音频过滤器
+- 更好的编码器支持
+- 各种修复和改进
+
+**媒体键支持:** 你终于可以用键盘上的媒体键来控制 Linux 上的 OBS 的播放或音量了。
+
+**新的音频过滤器:** OBS Studio 29 具有两个新的音频滤波器,一个向上压缩滤波器和一个 3 波段均衡器滤波器。
+
+**改进的英伟达视频和音频过滤器:** 对这些过滤器进行了各种改进。
+
+增加了一个新的屏蔽刷新滑块,同时支持时间处理,这应该是为了提供更好的屏蔽质量。
+
+**更好的编码器支持:**,OBS Studio 29 对几个编码器的支持得到了改善,例如:
+
+- Windows 上的用于 AMD [RX7000 系列][4] 的 AV1 编码器。
+- Windows 上的用于英特尔 [Arc GPU][5] 的 AV1 编码器。
+- Windows 上的英特尔 HEVC 编码器。
+- macOS 上的原生 HEVC 和 ProRes 编码器。
+
+> 📋 注意,这些编码器只支持 Windows 或 macOS。可悲的是,他们少了对 Linux 的支持。我们希望在 OBS Studio 的未来版本中加入这些功能。
+
+**各种修复和改进:** 除了上面列出的那些,OBS Studio 29 还有很多其他的变化,例如:
+
+- Websockets 5.1.0
+- 回放缓冲区的内存限制现在被限制在已安装的系统内存的 75%,而不是固定在 8GB。
+- 支持对 SRT 和 RIST 输出的加密和认证。
+- 能够检查和/或静音个别的浏览器底座。
+- 在视频捕获的情况下,支持更高的刷新率。
+
+关于更多的技术细节,你可以查看 [官方发布说明][6]。
+
+### 下载 OBS Studio 29

+MySQL 字符串指南
+======
+
+![][0]
+
+> 了解 MySQL 如何存储和显示你的字符串变量,以便你能更好地控制你的数据。
+
+字符串是你在 MySQL 中使用的最常见的数据类型之一。许多用户在他们的数据库中插入和读取字符串,而没有认真地了解过它们。本文旨在让你深入了解 MySQL 如何存储和显示你的字符串变量,以便你能更好地控制你的数据。
+
+你可以把字符串分成两类:二进制和非二进制。你可能在大多数时候想到的是非二进制字符串。非二进制字符串有字符集和排序的不同。另一方面,二进制字符串存储诸如 MP3 文件或图像等东西。即使你在二进制字符串中存储了一个词,比如“歌曲”,它的存储方式也与非二进制字符串不同。
+
+我将重点讨论非二进制字符串。MySQL 中的所有非二进制字符串都与字符集和排序相关。字符串的字符集控制哪些字符可以存储在字符串中,而它的排序方式控制当你显示字符串时如何排序。
+
+### 字符集
+
+要查看你系统中的字符集,请运行以下命令:
+
+```
+SHOW CHARACTER SET;
+```
+
+这个命令将输出四列数据,包括字符集:
+
+- 名称
+- 简要描述
+- 默认的排序方式
+- 字符集中每个字符的最大尺寸
+
+MySQL 过去默认为 `latin1` 字符集,但自 8.0 版以来,默认为 `utf8mb4`。现在的默认排序方式是 `utf8mb4_0900_ai_ci`。`ai` 表示该排序对音调不敏感( `á` = `a`),而 `ci` 则指定它对大小写不敏感(`a` = `A`)。
+
+不同的字符集将其字符存储在内存中不同大小的块中。例如,从上面的命令可以看出,存储在 `utf8mb4` 的字符被存储在 1 到 4 个字节大小的内存中。如果你想看看一个字符串是否包含多字节的字符,你可以使用 `CHAR_LENGTH()` 和 `LENGTH()` 函数。`CHAR_LENGTH()` 显示一个字符串包含多少个字符,而 `LENGTH()` 显示一个字符串有多少个字节,根据字符集的不同,它可能与一个字符串的字符长度相同,也可能不相同。下面是一个例子:
+
+```
+SET @a = CONVERT('data' USING latin1);
+
+SELECT LENGTH(@a), CHAR_LENGTH(@a);
+
++------------+-----------------+
+| LENGTH(@a) | CHAR_LENGTH(@a) |
++------------+-----------------+
+| 4 | 4 |
++------------+-----------------+
+```
+
+这个例子表明,`latin1` 字符集以单字节为单位存储字符。其他字符集,如 `utf16`,允许多字节的字符:
+
+```
+SET @b = CONVERT('data' USING utf16);
+
+SELECT LENGTH(@b), CHAR_LENGTH(@b);
+
++------------+------------------+
+| LENGTH(@b) | CHAR_LENGTH(@b) |
++------------+------------------+
+| 8 | 4 |
++------------+------------------+
+```
+
+### 排序
+
+当你运行带有 `ORDER BY` 子句的 SQL 语句时,字符串排序方式将决定值的显示方式。你对排序方式的选择是由你选择的字符集决定的。当你运行上面的 `SHOW CHARACTER SET` 命令时,你看到了每个字符集的默认排序方式。你可以很容易地看到某个特定字符集的所有排序方式。例如,如果你想查看 `utf8mb4` 字符集允许哪些排序,请运行:
+
+```
+SHOW COLLATION LIKE 'utf8mb4%';
+```
+
+排序方式可以是不区分大小写的,也可以是区分大小写的,或者是二进制的。让我们建立一个简单的表,向其中插入一些值,然后用不同的排序方式查看数据,看看输出结果有什么不同:
+
+```
+CREATE TABLE sample (s CHAR(5));
+
+INSERT INTO sample (s) VALUES
+ ('AAAAA'), ('ccccc'), ('bbbbb'), ('BBBBB'), ('aaaaa'), ('CCCCC');
+
+SELECT * FROM sample;
+
++-----------+
+| s |
++-----------+
+| AAAAA |
+| ccccc |
+| bbbbb |
+| BBBBB |
+| aaaaa |
+| CCCCC |
++-----------+
+```
+
+在不区分大小写的情况下,你的数据会按字母顺序返回,但不能保证大写的单词会排在小写的单词之前,如下图所示:
+
+```
+SELECT * FROM sample ORDER BY s COLLATE utf8mb4_turkish_ci;
+
++-----------+
+| s |
++-----------+
+| AAAAA |
+| aaaaa |
+| bbbbb |
+| BBBBB |
+| ccccc |
+| CCCCC |
++-----------+
+```
+
+另一方面,当 MySQL 运行大小写敏感的搜索时,每个字母的小写将排在大写之前:
+
+```
+SELECT * FROM sample ORDER BY s COLLATE utf8mb4_0900_as_cs;
+
++-----------+
+| s |
++-----------+
+| aaaaa |
+| AAAAA |
+| bbbbb |
+| BBBBB |
+| ccccc |
+| CCCCC |
++-----------+
+```
+
+而按二进制排序方式将返回所有大写的值,然后再返回小写的值:
+
+```
+SELECT * FROM sample ORDER BY s COLLATE utf8mb4_0900_bin;
+
++-----------+
+| s |
++-----------+
+| AAAAA |
+| ccccc |
+| bbbbb |
+| BBBBB |
+| aaaaa |
+| CCCCC |
++-----------+
+```
+
+如果你想知道一个字符串使用哪种字符集和排序,你可以使用被恰当命名的 `charset` 和 `collation` 函数。运行 MySQL 8.0 或更高版本的服务器将默认使用 `utf8mb4` 字符集和 `utf8mb4_0900_ai_ci` 排序:
+
+```
+SELECT charset('data');
+
++-------------------+
+| charset('data') |
++-------------------+
+| utf8mb4 |
++-------------------+
+
+SELECT collation('data');
+
++--------------------+
+| collation('data') |
++--------------------+
+| utf8mb4_0900_ai_ci |
++--------------------+
+```
+
+你可以使用 `SET NAMES` 命令来改变所使用的字符集或排序方式。
+
+要从 `utf8mb4` 字符集改为 `utf16`,运行这个命令:
+
+```
+SET NAMES 'utf16';
+```
+
+如果你想选择默认以外的排序方式,你可以在 `SET NAMES` 命令中添加一个 `COLLATE` 子句。
+
+例如,假设你的数据库存储西班牙语的单词。MySQL 的默认排序(`utf8mb4_0900_ai_ci`)将 `ch` 和 `ll` 视为两个不同的字符,并将它们排序。但在西班牙语中,`ch` 和 `ll` 是单独的字母,所以如果你想让它们按正确的顺序排序(分别排在 `c` 和 `l` 之后),你需要使用不同的排序。一个选择是使用 `utf8mb4_spanish2_ci` 排序方式:
+
+```
+SET NAMES 'utf8mb4' COLLATE 'utf8mb4_spanish2_ci';
+```
+
+### 储存字符串
+
+MySQL 允许你为你的字符串值选择不同的数据类型。(甚至比其他流行的数据库,如 PostgreSQL 和 MongoDB 更多。)
+
+下面是 MySQL 的二进制字符串数据类型的列表、它们的非二进制对应物,以及它们的最大长度:
+
+- `binary`:`char`(255)
+- `varbinary`:`varchar`(65,535)
+- `tinyblob`:`tinytext`(255)
+- `blob`:`text`(65,535)
+- `mediumblob`:`mediumtext`(16,777,215)
+- `longblob`:`longtext`(4,294,967,295)
+
+要记住的一件重要事情是,与被存储在可变长度的字段中的 `varbinary`、`varchar`、`text` 和 `blob` 类型不同(也就是说,只使用需要的空间),MySQL 将二进制(`binary`)和字符(`char`)类型存储在固定长度的字段。因此,像 `char(20)` 或 `binary(20)` 这样的值将总是占用 20 个字节,即使你在其中存储了少于 20 个字符。对于二进制类型,MySQL用 ASCII NUL 值(`0x00`)填充这些值,对于 字符类型,用空格填充。
+
+在选择数据类型时要考虑的另一件事是,你是否希望在字符串后面的空格被保留或剥离。在显示数据时,MySQL 会从以字符数据类型存储的数据中剥离空格,但不会剥离 `varchar` 的空格。
+
+```
+CREATE TABLE sample2 (s1 CHAR(10), s2 VARCHAR(10));
+
+INSERT INTO sample2 (s1, s2) VALUES ('cat ', 'cat ');
+
+SELECT s1, s2, CHAR_LENGTH(s1), CHAR_LENGTH(s2) FROM sample2;
+
++---------+---------+-----------------------------------+
+| s1 | s2 | CHAR_LENGTH(s1) | CHAR_LENGTH(s2) |
++---------+---------+-----------------------------------+
+| cat | cat | 3 | 10 |
++---------+---------+-----------------------------------+
+```
+
+### 总结
+
+字符串是数据库中最常用的数据类型之一,而 MySQL 仍然是当今最流行的数据库系统之一。我希望你能从这篇文章中学到一些新的东西,并能用你的新知识来提高你的数据库技能。

+酷冷至尊(CoolerMaster)的 MasterPlus 软件即将开源
+======
+
+> MasterPlus 将被彻底改造并推出开源版本?听起来不错!
+
+![][1]
+
+大多数游戏/外设软件套装要么是专有的,要么是没有对 Linux 的官方支持。
+
+因此,我们必须不断寻找开源工具来配置我们的硬件以获得原生功能。
+
+像 [Piper][2]、[OpenRGB][3]、[Solaar][4] 等在这些情况下都很有用。
+
+但是,有时候,即使是这些也是不够的。
+
+幸运的是,[酷冷至尊(CoolerMaster)][5] 已经决定发布其 [MasterPlus][6] 软件的开源版本,旨在为其散热器和第三方的散热器提供服务。
+
+**虽然这并不能保证它可以用在 Linux 系统上,但我们绝对可以期待它。**
+
+此举也应该鼓励雷蛇和罗技这样公司考虑制作精简过的开源工具。
+
+让我们看看酷冷至尊打算怎么做。
+
+### MasterPlus 开源版本:我们目前所知的情况
+
+![酷冷至尊 Masterplus 改版][7]
+
+**酷冷至尊在最近的 [CES 2023][8] 活动中透露了他们计划发布新的 MasterPlus 开源版本**。感谢来自 [Boring Text Reviews][9] 的 Albert 让我们注意到了这一点。
+
+**预期会有什么?** 对 MasterPlus 软件进行了全面的重新设计,有一个 API 插件系统,允许非酷冷至尊散热器与之整合。
+
+他们已经澄清,酷冷至尊的独有功能不能配合其他散热器一起工作。因此,诸如检测 AIO 散热器的泄漏或计算 PSU 的效率等,都不能对第三方产品进行跟踪。
+
+相反,该应用程序将只支持读取基本的性能信息,如温度和风扇速度,并能够配置 ARGB 设备。
+
+如果你问我,**这总比没有好。** 而且,如果你的系统碰巧使用了酷冷至尊的组件,这对你来说是一个令人兴奋的消息!
+
+酷冷至尊还展示了 API 系统的潜在应用,让它与一个照片应用程序挂钩,用它来控制集成在电脑机箱侧面的辅助显示器。
+
+此外,他们还介绍了其软件的全面云整合。但遗憾的是,这部分不会开源。
+
+**什么时候?** 我们还没有 MasterPlus 开源的具体发布日期。
+
+但是,如果让我猜,2023 年的某个时候是最好的选择。
+
+💬 _即使该工具没有被确认可以在 Linux 上工作,对开源工具来说也是一个好的开始,不是吗?你怎么看?_

+
+Mastodon 继续增长,Medium 的新社区平台也加入了
+======
+
+> Mastodon 的又一次胜利!Medium 为其用户推出了一个 Mastodon 实例。
+
+![][1]
+
+Mastodon 在最近一段时间的增长是巨大的;越来越多的人正在转向这个 Twitter 的替代品。
+
+如果你不熟悉 Mastodon,它是目前 [最好的主流社交媒体替代品][2] 之一,有可能成为 Twitter 的替代品,它是 **完全开源和去中心化的**。
+
+随着 Twitter 的不断发生变化和去年埃隆·马斯克对它的收购,更多的用户开始对 Mastodon 这个平台产生了浓厚的兴趣。
+
+Vivaldi [最近推出了][3] 其由 Mastodon 驱动的社区,[Mozilla 基金会][4] 也在考虑类似的东西。
+
+现在,[Medium][5] 已经向前迈出了一步,推出了它们的 Mastodon 实例。
+
+### Medium 启动了一个由 Mastodon 驱动的社区
+
+在 [最近的公告][6] 中,Medium 在 [me.dm][7] 推出了其 Mastodon 实例,专注于 “帮助他们的作者、出版物和读者在 联盟宇宙 中找到一个家”。
+
+该网站(即 Mastodon 实例)旨在成为 Medium 的用户的专属空间。
+
+![][8]
+
+换句话说,它将成为 Medium 用户的专属社交网络平台。
+
+有了这个网络平台,他们也可以开始进行 500 字以内的短文写作了。
+
+Medium 的 CEO 提到:
+
+> 相比之下,Mastodon 主要是为 500 字以内的短文写作服务的。用一个不太双关的说法:今天,我们正在借助 Mastodon 上的实例(me.dm)将我们用于发表长文的 Medium 扩展到短文 medium(小写 m)。除了更简短的形式外,Mastodon 还带来了围绕联盟概念的重要创新。
+
+因此,看起来 Medium 正在试水和尝试新的东西。
+
+对于那些喜欢一目了然的内容而不是冗长信息的用户来说,可能是一件好事。
+
+如果操作得当,这对他们来说会有很好的效果。
+
+**那么,你怎样才能加入 Medium 的 Mastodon 平台?
+
+> 💡 你看,最初,**只有选定的作者和出版物** 才能进入这个 Mastodon 实例。现有的 Medium 用户可以尝试发送一个 [注册请求][9],但要经过他们的批准。
+
+因此,如果你发送一个注册请求,你得等待批准。
+
+他们还计划作为付费会员的额外服务来邀请作家和读者。
+
+他们已经在为他们的 Mastodon 实例开发一个 “用 Medium 注册” 的选项,这应该是为了让你更容易开始使用。
+
+关于这一点,他们提到:
+
+> 有这么多的 Mastodon 实例可供选择,我们计划让 me.dm 一开始就有几个重要的好处:可靠的基础设施和审核,一个短域名让你更容易分享你的用户名,为新用户提供更好的入门培训,以及一个有趣的本地信息源。
+
+### 去中心化和开源平台的步伐加快了
+
+去中心化的平台正在变得比人们十年前预期的更加流行。
+
+最大的促成因素是大型科技公司越来越多的不稳定的变化和决定,迫使用户不断调整他们在社交媒体平台上的互动方式和理由。
+
+有了开源和去中心化的平台,用户得到了透明度,更多的数据控制,以及更多的自由。
+
+我们可能没有想到,Mastodon 作为一个平台,逐渐成为各种组织的社区建设的一个重要组成部分。因此,我们非常期待在不久的将来看到更多变化。
+
+💭 欢迎在下面的评论中分享你的想法。

-Privacy-Preserving Ads Make a Debut on Brave Search
-======
-
-Brave Search is testing privacy-preserving ads. But, the Brave browser does not seem to block them by default.
-
-![Privacy-Preserving Ads Make a Debut on Brave Search][1]
-
-Brave Search is an independent search engine that claims not to track its users and provides a safe and secure search experience.
-
-It aims to be a privacy-friendly alternative to the extensive tech services from Microsoft and Google.
-
-With a [recent announcement][2], they introduced a new feature to Brave Search. The search will now show '_privacy-preserving_' ads as part of a global beta program.
-
-What does this mean? Allow me to explain.
-
-### Privacy-Preserving Ads: Meaning?
-
-![brave search privacy preserving ads][3]
-
-Brave is planning to run ads on their search platform; they claim that these ads are anonymous, are marked, and follow its commitment of putting users first.
-
-These ads are said to be clearly labeled and are integrated into Brave Search.
-
-To display relevant advertisements, Brave Search will only use your **search query, country, and device type**.
-
-So, in theory, this should stop them from keeping a profile of your searches.
-
-They also add that:
-
-> Brave Search ads protect users’ data and anonymity, while supporting their access to independent and transparent search as a true alternative to Big Tech search engines.
-
-This has been released as a beta test globally, where Brave Search users will be shown text-based ads in search results.
-
-Users who opted for Brave Private Ads (for _Brave Rewards_) and are using the latest version of Brave won't be shown search ads since these are not yet eligible for BAT earnings.
-
-Additionally, they offer a '**Search Premium**' subscription for an ad-free search experience, which costs **$3 per month**.
-
-With this subscription, you get a completely ad-free search experience while also supporting Brave.
-
-### Is This a Step in the Right Direction?
-
-Even though Brave Search is based on an **open-source search project**[Tailcat][4], they have no plans to make it open-source.
-
-So, Brave Search already has a red flag 🚩 for many privacy enthusiasts who prefer open-source solutions for their transparency.
-
-**Will privacy-preserving ads make a difference, just like Brave Search's original claims for its search engine?**
-
-Well, I certainly hope so. Why? **Because we need more competitors to Google**. And something is better than nothing.
-
-Even without open-source code, we will have to sit back and see what kind of transparency they provide in their advertisement testing soon.
-
-Though, the implementation of Brave's privacy-preserving ads has got a few users upset.
-
-A [comment][5] made by a Reddit user on the official Subreddit of Brave Browser mentions:
-
-> Putting in an exception for your own ads is in exceptionally bad taste. All the marketing fluff around "independent, private search" is not an excuse.
-
-Brave Browser seems to be **not blocking Brave search ads** with its in-built ad-blocker (Brave Shields).
-
-On that, a member of the Brave support team clarified:
-
-> Shields at this time does not block 1st part, non tracking ads by default anyway (with the exception of setting to Aggressive, I believe) so it's actually just following the standard we've already set.
-
-So, you can block the Brave search ads with the privacy protection settings set to aggressive, I believe?
-
-However, not everyone prefers the aggressive blocker. So, let us see how things turn out for Brave search ad experimentation.
-
-💭 **Thoughts? Feel free to share them in the comments section.**

-Linux Mint 21.1 beta is now available for testing
-======
-
-![][1]
-
-**Check out the new features of Linux Mint 21.1 beta, which is now slowly available for download in mirrors. The official announcement is awaited.**
-
-![Linux Mint 21.1 beta Cinnamon desktop][2]
-
-Linux Mint 21.1 is the first point release of the 21 series and will be released before Christmas this year. Codenamed “Vera”, which was [announced a few weeks back][3], is now available for beta testing.
-
-The beta testing is expected to continue for at least a week before the final release. Since it is the first point, the feature list is not at that higher end. But some significant updates are arriving in the final release.
-
-### Linux Mint 21.1 beta & new features
-
-One of the biggest updates to the Driver Manager in this release is the ability to run the app with your user account without requiring a password to launch it. This is a major convenience, as it means you don’t have to enter a password every time you want to use the Driver Manager. In addition, when you remove a driver, the app now purges it from the system completely, ensuring that no trace of the driver remains on your computer.
-
-Another key update to the Driver Manager is the ability to detect USB installation media and help you mount them. This is particularly useful if you’re installing software or drivers from a USB drive, as it makes the process much easier and more streamlined.
-
-In addition to these updates, the Mint team has also included a feature for verifying the checksum of ISO files. This is an important part of any installation process, as it ensures that your ISO file is legitimate and hasn’t been tampered with. While other [utilities][4] are available for verifying ISO checksums, including command line tools, it’s nice to see this feature included in the default desktop environment.
-
-Another change in this release is the default desktop view, which is expected to be updated. The default icons for the Computer, Home, Trash, and Network are now hidden from view, as the Computer icon is already included in the Panel, and the other icons are not used as frequently.
-
-Other noteworthy updates in this release include the inclusion of Timeshift backports for prior releases (such as Mint 20.x) and an updated version of Blueman. Overall, this is a solid point release that includes several useful updates and bug fixes.
-
-![New default icon set and bibata cursor][5]
-
-Finally, you may notice the “green” icon sets and the cursor is different in the Cinnamon flavour. Linux Mint 21.1 brings the “Mint-y-Aqua” theme and the stunning “Bibata-modern” cursor theme to pair with it. Both of them look awesome together, giving a much-needed fresh vibe.
-
-### Summary of changes
-
-- First point release of Linux Mint 21, based on Ubuntu 22.04.1 release
-- Linux Kernel 5.15 LTS
-- Cinnamon 5.6.4 desktop
-- Xfce 4.16 desktop
-- MATE 1.26 desktop
-- Friendly driver manager
-- Cleaner default desktop view with fewer icons
-- Default theme changes to “Mint-Y-Aqua” from the green-based icons
-- New cursor theme: Bibata (one of the best cursor theme in Linux)
-- A bunch of stunning wallpapers
-- And an array of bug fixes
-
-### Download and bug reporting for beta
-
-While the team is preparing for the official announcement, the ISO images are slowly becoming available to the public. As always, being a beta release, it may have bugs. So use it with caution.
-
-If you are running Linux Mint 21.0, don’t upgrade it yet. Wait for the final release.
-
-Still, if you want to try it on a virtual machine, download the Cinnamon, Xfce and MATE flavours of this beta release from the torrent links below.
-
-- [linuxmint-21.1-cinnamon-64bit-beta.iso.torrent][6]
-- [linuxmint-21.1-mate-64bit-beta.iso.torrent][7]
-- [linuxmint-21.1-xfce-64bit-beta.iso.torrent][8]
-
-I will update the changelog here once it is available. And finally, report any issues or bugs at the dedicated [21.1 beta bug tracking page][9].
-
-Cheers.

-Linen is a Google-Searchable Open-Source Alternative to Slack and Discord
-======
-
-An interesting open-source alternative to Slack and Discord.
-
-![Linen is a Google-Searchable Open-Source Alternative to Slack and Discord][1]
-
-Linen is an interesting open-source project brewing up.
-
-It aims to be an **open alternative to Slack and Discord**, focusing on making communities more accessible and helping reduce the support burden.
-
-It could be worth adding it as an open-source Slack alternative, but it is in its **early stages of development** when publishing this.
-
-**_What's different with Linen, exactly?_**
-
-- **Open Source**
-- **Unlimited history retention**
-- **Communities are Google searchable**
-- **Supports sync from Slack and Discord**
-- **Eliminate the need to join Slack/Discord for information**
-
-### Community-Focused Slack Alternative
-
-[Linen][2] pitches itself as an open-source app for communities rather than primarily targeting teams for collaboration/communication.
-
-![linen ui][3]
-
-In contrast, Slack is primarily for team discussions and collaboration. You cannot share the conversation through a URL or find the discussions indexed on search engines like Google.
-
-But with Linen, you can **find a URL for every conversation** that can be shared with anyone to view/join the conversation.
-
-![linen message url][4]
-
-Here's something for the test: [https://linen.dev/s/itsfoss/t/5099789/topic][5]
-
-**You can also find this conversation listed on Google** (it may take time to find it exactly).
-
-For example, suppose we are a community of an open-source project where we discuss an issue or a solution; listing it on Google enables more users to find out about it.
-
-Here's an example of a conversation listed on Google that could help me if I was exploring solutions to fix my code issues with Kotlin:
-
-![linen google search][6]
-
-As a developer/user, I could view the conversation, get my answer, and move on without troubling anyone else in the community with a repeat question.
-
-**Sounds lovely, right? Linen helps you enhance community support.**
-
-Sure, you can use it for your team communication as well. But, it is a more appropriate solution to create an open community chat network.
-
-Currently, it does not provide the feature to create a private community for the public. They only use it for internal team discussions, per their [GitHub page][7].
-
-![][8]
-
-### How To Get Started?
-
-Linen does not support self-hosting at the moment. But, their roadmap on [GitHub][9] indicates that it has been planned for the near future.
-
-So, you can [sign up for a free account][10] using the official cloud instance or opt for the business/premium edition to use custom domain/branding benefits for your team.
-
-You can **import your Slack/Discord conversations for free**.
-
-> 💡 The free community edition is hosted under Linen.dev where you rely on community support. Opt for its premium edition to get priority support.
-
-Linen may not be for everyone, but it sounds like a useful idea for many communities and teams.
-
-_💬 What do you think about it? Let me know in the comments below._

-Apple Silicon GPU Driver is Now Available in Asahi Linux
-======
-
-We finally have a GPU driver for Apple M silicon systems on Asahi Linux.
-
-![Apple Silicon GPU Driver is Now Available in Asahi Linux][1]
-
-Asahi Linux aims to be a port of Linux for Apple Silicon Macs; work started on it back in 2020, right after the launch of Apple's M1 chips at the WWDC event.
-
-A small team is behind all the development behind Asahi Linux and reverse engineering stuff; they have been quite busy since the last time we looked at their work.
-
-Previously, they worked on improving support for Apple SoCs such as the M1, M1 Pro, and M1 Max. They provided varying levels of support for devices that used these chips.
-
-It still is a work in progress, but promising results in 2022.
-
-They have now taken it further by providing initial support for Apple Silicon GPUs by releasing drivers (in _alpha_).
-
-That sounds great! 😃
-
-Let me take you through the gist of it.
-
-### Hardware Acceleration With Desktop Environments and Old Games
-
-![asahi linux running quake3][2]
-
-Introduced as an alpha-stage GPU driver, it can run desktop environments and a few games smoothly.
-
-**The implementation:** The driver features a work-in-progress implementation of OpenGL 2.1 and OpenGL ES 2.0 for current Apple M-series systems.
-
-They also mention that:
-
-> These drivers have not yet passed the OpenGL (ES) conformance tests. There will be bugs!
-
-So, you can expect plenty of hiccups along the way should you choose to run applications using these drivers.
-
-**How it works now?:** In its current form, the driver can run desktop environments like GNOME and KDE Plasma with hardware acceleration.
-
-Even older games like [Quake3][3] and [Neverball][4] can run quite well, with these and the desktop environments running at a solid **60 fps at 4k resolution**.
-
-Many users may also notice that quite a few apps don't work with this driver right away. On that, the developers mention:
-
-> Since the driver is still in development, there are lots of known issues and we’re still working hard on improving conformance test results. Please don’t open new bugs for random apps not working! It’s still the early days and we know there’s a lot of work to do.
-
-**What does the future hold?:** The developers have said that while OpenGL (ES) 2 suffices for some applications, newer applications will require new features such as multiple render targets, multisampling, and transform feedback.
-
-All of this can be achieved with OpenGL (ES) 3, and work on that has already started. But, it will need a lot of developmental effort to get ready.
-
-They have also hinted at support for Vulkan in the future, although it is a long time in the making.
-
-Here's what they tell about it:
-
-> We’re working on it! Although we’re only shipping OpenGL right now, we’re designing with Vulkan in mind. Most of the work we’re putting toward OpenGL will be reused for Vulkan. We estimated that we could ship working OpenGL 2 drivers much sooner than a working Vulkan 1.0 driver, and we wanted to get hardware accelerated desktops into your hands as soon as possible.
-
-When a Reddit user [asked][5] about **120 Hz support for MacBook Pro**, one of the maintainers had this to say:
-
-> 120Hz is disabled because it still is capped at 60Hz if we do nothing and was having other weird issues. It's still unclear exactly how VRR works on macOS, we need to figure that out first.
-
-It seems like Asahi Linux has a lot of room to grow, and improvements like this to GPU drivers on a new Silicon system should finally open up new opportunities in terms of performance.
-
-Linux users have been asking for something like this for a long time, and it is now closer to becoming a reality than ever before.
-
-If you are feeling adventurous and want to try the new GPU driver, you can try installing it on your Asahi Linux system. Refer to the [official announcement][6] for instructions to experiment with it.

-Mastodon's Adoption Gets a Boost With Vivaldi Browser Integration
-======
-
-Vivaldi's making an effort to have more users join Mastodon with its new update. That's nice to see!
-
-![Mastodon's Adoption Gets a Boost With Vivaldi Browser Integration][1]
-
-Vivaldi browser is one of the best web browsers for Linux (Windows, macOS, and mobile platforms).
-
-I know it is not an open-source pick, but it gets all the lead with its tab management, customizability, and productivity features. And it treats me better than Firefox nowadays (Mozilla, we still need you to do better)🙄
-
-**Note:**_Vivaldi is **not open-source**. Most of it is based on Chromium, for which you can find the [source code][2]._
-
-If you did not know, Vivaldi recently built a Mastodon instance (**Vivaldi Social**) to encourage people to use open-source and decentralized social media platforms.
-
-It is one of the best Mastodon instances you can join:
-
-To take this further, **Vivaldi 5.6 update** has integrated access to its Mastodon instance from within its web browser.
-
-> 🐘 Hey! We are on [Mastodon][3] for a while; follow **us if you haven't already**! 😄
-
-### Access Mastodon From Web Panels
-
-Web panels on Vivaldi make it a breeze to multitask. You can keep browsing or working on what you want and still access additional services in a single click.
-
-Here's what it looks like:
-
-![mastodon on vivaldi][4]
-
-I can access Vivaldi's Mastodon instance quickly.
-
-Of course, you can add your custom web panel for any Mastodon instance you like.
-
-![vivaldi web panel addition][5]
-
-However, I believe out-of-the-box integration should encourage Vivaldi users to try Mastodon if they haven't yet.
-
-In the official announcement, Vivaldi also explains it properly for its users:
-
-> [Vivaldi Social][6] came into existence as we love the idea of distributed social networks based on open standards. We want to offer better alternatives to people to communicate in an algorithm-free environment with no surveillance capitalism, devoid of tracking or data profiling.The Mastodon server platform communicates through the [Activity Pub][7] standard, a decentralized social networking and messaging protocol recommended by the [World Wide Web Consortium (W3C)][8]. Any platform or application that implements ActivityPub becomes a part of a massive social network. This big social network is also called the [Fediverse][9] (“federated” + “universe”).
-
-Before anyone gets their pitchfork ready, I want Vivaldi to be 100% open-source, but we also want more companies in the mainstream to adopt and encourage the use of open-source tech.
-
-And I think Vivaldi has got an excellent approach to that.
-
-So, this integration should ultimately let every Vivaldi (or Linux user) use Mastodon more than often.
-
-In addition to this change, Vivaldi 5.6 release involves a couple of improvements that include:
-
-- A new search engine (You.com)
-- Panels joining editable toolbars
-- Revamped settings page
-- Pin tab stacks (_this is exciting!_)
-
-You can update the browser to get the latest version or download Vivaldi 5.6 on its official website.

+Linux is All Set to Disable Microsoft's RNDIS Drivers
+======
+
+The Linux Kernel will no longer support RNDIS drivers. A good move? What does this mean for you? Find out here.
+
+![Linux is All Set to Disable Microsoft's RNDIS Drivers][1]
+
+Microsoft's RNDIS protocol, short for Remote Network Driver Interface Specification, is a proprietary USB protocol for virtual Ethernet functionality on computers.
+
+The most common use case of this would be using your phone's mobile network to connect to the internet on your computer via USB, also known as [Tethering][2].
+
+Even though it mainly works on Windows, it has been part of the Linux kernel for a while now.
+
+But that is set to change soon.
+
+### Say Goodbye to RNDIS Protocol?
+
+![][3]
+
+**What is happening?:** On Monday, [Greg Kroah-Hartman][4] created the [usb.git rndis-removal][5] branch, where he mentions disabling the implementation of all RNDIS protocol drivers on Linux.
+
+With the commit, he mentions:
+
+> The Microsoft RNDIS protocol is, as designed, insecure and vulnerable onany system that uses it with untrusted hosts or devices. Because theprotocol is impossible to make secure, just disable all rndis drivers toprevent anyone from using them again.Windows only needed this for XP and newer systems, Windows systems older than that can use the normal USB class protocols instead, which do not have these problems.Android has had this disabled for many years so there should not be anyreal systems that still need this.
+
+As initially reported by [Phoronix][6], once this protocol is marked 'BROKEN' in the Kconfig option, it will stay there for a while and ultimately be removed from the kernel.
+
+But **why?**
+
+The implementation of RNDIS is known to be a mess on platforms apart from Windows and poses quite a few security risks. In addition, RNDIS is not being used as widely as before, and the security risks it presents might be one of the main reasons for this decision.
+
+**Does this have an impact on current users? Should you be worried?**
+
+If we look at a [Reddit thread][7] discussing this upcoming change, we would see that many users remain curious **if this would break USB tethering for everyone.**
+
+Users seem confused about this move, considering many Android phones still use RNDIS instead of CDC NCM (a newer protocol) 😕 Not just users; a [Kernel Networking Developer at Google][8] also flagged this issue, but we do not see a response to that yet.
+
+**But not everyone uses mainline Linux Kernel? Should you stick to an LTS version of the kernel if you do not want to be impacted by this change?**
+
+Furthermore, users wanted more clarity on how this does not impact everyone.
+
+But, as of now, **Greg** may not have mentioned a lot of details to convince some of the concerned users.
+
+🤔 Of course, we aren't Linux Kernel maintainers. So, it is best to wait until this commit gets through, and I hope that the Linux Kernel maintainers shed more light on it than we already know.
+
+💭 _What are your thoughts on this planned change for the Linux Kernel? Share your thoughts in the comments down below._

-Understanding Linus's Law for open source security
-======
-Linus's Law is that given enough eyeballs, all bugs are shallow. How
-does this apply to open source software security?
-![Hand putting a Linux file folder into a drawer][1]
-
-In 2021, there are more reasons why people love Linux than ever before. In this series, I'll share 21 different reasons to use Linux. This article discusses Linux's influence on the security of open source software.
-
-An often-praised virtue of open source software is that its code can be reviewed (or "audited," as security professionals like to say) by anyone and everyone. However, if you actually ask many open source users when the last time they reviewed code was, you might get answers ranging from a blank stare to an embarrassed murmur. And besides, there are some really big open source applications out there, so it can be difficult to review every single line of code effectively.
-
-Extrapolating from these slightly uncomfortable truths, you have to wonder: When nobody looks at the code, does it really matter whether it's open or not?
-
-### Should you trust open source?
-
-We tend to make a trite assumption in hobbyist computing that open source is "more secure" than anything else. We don't often talk about what that means, what the basis of comparison is ("more" secure than what?), or how the conclusion has even been reached. It's a dangerous statement to make because it implies that as long as you call something _open source_, it automatically and magically inherits enhanced security. That's not what open source is about, and in fact, it's what open source security is very much against.
-
-You should never assume an application is secure unless you have personally audited and understood its code. Once you have done this, you can assign _ultimate trust_ to that application. Ultimate trust isn't a thing you do on a computer; it's something you do in your own mind: You trust software because you choose to believe that it is secure, at least until someone finds a way to exploit that software.
-
-You're the only person who can place ultimate trust in that code, so every user who wants that luxury must audit the code for themselves. Taking someone else's word for it doesn't count!
-
-So until you have audited and understood a codebase for yourself, the maximum trust level you can give to an application is a spectrum ranging from approximately, _not trustworthy at all_ to _pretty trustworthy_. There's no cheat sheet for this. It's a personal choice you must make for yourself. If you've heard from people you strongly trust that an application is secure, then you might trust that software more than you trust something for which you've gotten no trusted recommendations.
-
-Because you cannot audit proprietary (non-open source) code, you can never assign it _ultimate trust_.
-
-### Linus's Law
-
-The reality is, not everyone is a programmer, and not everyone who is a programmer has the time to dedicate to reviewing hundreds and hundreds of lines of code. So if you're not going to audit code yourself, then you must choose to trust (to some degree) the people who _do_ audit code.
-
-So exactly who does audit code, anyway?
-
-Linus's Law asserts that _given enough eyeballs, all bugs are shallow_, but we don't really know how many eyeballs are "enough." However, don't underestimate the number. Software is very often reviewed by more people than you might imagine. The original developer or developers obviously know the code that they've written. However, open source is often a group effort, so the longer code is open, the more software developers end up seeing it. A developer must review major portions of a project's code because they must learn a codebase to write new features for it.
-
-Open source packagers also get involved with many projects in order to make them available to a Linux distribution. Sometimes an application can be packaged with almost no familiarity with the code, but often a packager gets familiar with a project's code, both because they don't want to sign off on software they don't trust and because they may have to make modifications to get it to compile correctly. Bug reporters and triagers also sometimes get familiar with a codebase as they try to solve anomalies ranging from quirks to major crashes. Of course, some bug reporters inadvertently reveal code vulnerabilities not by reviewing it themselves but by bringing attention to something that obviously doesn't work as intended. Sysadmins frequently get intimately familiar with the code of an important software their users rely upon. Finally, there are security researchers who dig into code exclusively to uncover potential exploits.
-
-### Trust and transparency
-
-Some people assume that because major software is composed of hundreds of thousands of lines of code, it's basically impossible to audit. Don't be fooled by how much code it takes to make an application run. You don't actually have to read millions of lines. Code is highly structured, and exploitable flaws are rarely just a single line hidden among the millions of lines; there are usually whole functions involved.
-
-There are exceptions, of course. Sometimes a serious vulnerability is enabled with just one system call or by linking to one flawed library. Luckily, those kinds of errors are relatively easy to notice, thanks to the active role of security researchers and vulnerability databases.
-
-Some people point to bug trackers, such as the [Common Vulnerabilities and Exposures (CVE)][2] website, and deduce that it's actually as plain as day that open source isn't secure. After all, hundreds of security risks are filed against lots of open source projects, out in the open for everyone to see. Don't let that fool you, though. Just because you don't get to see the flaws in closed software doesn't mean those flaws don't exist. In fact, we know that they do because exploits are filed against them, too. The difference is that _all_ exploits against open source applications are available for developers (and users) to see so those flaws can be mitigated. That's part of the system that boosts trust in open source, and it's wholly missing from proprietary software.
-
-There may never be "enough" eyeballs on any code, but the stronger and more diverse the community around the code, the better chance there is to uncover and fix weaknesses.
-
-### Trust and people
-
-In open source, the probability that many developers, each working on the same project, have noticed something _not secure_ but have all remained equally silent about that flaw is considered to be low because humans rarely mutually agree to conspire in this way. We've seen how disjointed human behavior can be recently with COVID-19 mitigation:
-
- * We've all identified a flaw (a virus).
- * We know how to prevent it from spreading (stay home).
- * Yet the virus continues to spread because one or more people deviate from the mitigation plan.
-
-
-
-The same is true for bugs in software. If there's a flaw, someone noticing it will bring it to light (provided, of course, that someone sees it).
-
-However, with proprietary software, there can be a high probability that many developers working on a project may notice something not secure but remain equally silent because the proprietary model relies on paychecks. If a developer speaks out against a flaw, then that developer may at best hurt the software's reputation, thereby decreasing sales, or at worst, may be fired from their job. Developers being paid to work on software in secret do not tend to talk about its flaws. If you've ever worked as a developer, you've probably signed an NDA, and you've been lectured on the importance of trade secrets, and so on. Proprietary software encourages, and more often enforces, silence even in the face of serious flaws.
-
-### Trust and software
-
-Don't trust software you haven't audited.
-
-If you must trust software you haven't audited, then choose to trust code that's exposed to many developers who independently are likely to speak up about a vulnerability.
-
-Open source isn't inherently more secure than proprietary software, but the systems in place to fix it are far better planned, implemented, and staffed.

-Is Open-Source Software Secure?
-======
-
-Being someone who prefers [Linux for desktop][1] and encourages using open-source software, you may expect the answer to the question raised in the headline with a big “**Yes**“.
-
-But I am not going to limit discussing the benefits of open-source software. Let us explore more!
-
-Here, I plan to share my thoughts on if open-source software is secure and what are the things involved in it that make secure or insecure.
-
-### Why Should You Care if Open-Source Software is Secure?
-
-No matter whether you use [Linux][2] or any other operating system, you will be surrounded with open-source software in some way (directly/indirectly).
-
-To give you an example, most of the proprietary software tools depend on some form of open-source libraries to make things work.
-
-Furthermore, there is a reason why companies of various scale (including Google, Microsoft, and Facebook) rely on open-source software or contribute their resources to the open-source community in one way or the other.
-
-Hence, the security of open-source software is something essential to know about.
-
-### Myths About Open-Source Software Security
-
-![][3]
-
-While there are several arguments to pitch the cons of open-source software in terms of security, some of them just do not make any sense.
-
-#### Anyone Can See & Exploit the Code
-
-The code is accessible to everyone, yes. But just because you can see the code—does that mean anyone can exploit it?
-
-**Not really.**
-
-Even though anyone can create a fork (or copy) of the software, the original software cannot be manipulated easily.
-
-Usually, the project maintainer (or a group of them) manage the code repository and accept the commits from contributors. The code is reviewed before approval. And no one can hijack the code just like that.
-
-**It takes effort for an attacker to exploit a vulnerability or add malicious code in a software, no matter if it is open-source or closed source.**
-
-#### Without Dedicated Resources, Security Breaks down
-
-Many believe that without dedicated employees or a team for an open-source software, it is difficult to maintain security.
-
-In contrast, with several types of contributors joining and leaving, the software gets more attention from a wide range of developers.
-
-And they may be able to spot security issues better than a few employees assigned for a proprietary software.
-
-Some projects from the likes of Mozilla have a dedicated team to effectively iron out security issues. Similarly, most of the successful open source projects have plenty of resources to dedicate for security.
-
-Hence, the open-source software ecosystem is a mixed bag for security. Even without dedicated resources, the projects get help from various contributors, and some are profitable to a great extent which helps them dedicate more resources.
-
-### Open Source Software is Secure: Here’s How
-
-![][3]
-
-Now that we have tackled the myths, let me highlight how open-source software deals with security issues.
-
-In other words, the benefits in security with open-source software.
-
-Not to forget, the perks of open-source software translate to some of the reasons why [Linux is better than Windows][4].
-
-#### More Eyes Looking at the Code
-
-Unlike a proprietary software, access to code is not limited to a few developers.
-
-Some projects may even have thousands of developers watching the code, reviewing them, and flagging or fixing security issues.
-
-And this gives an edge over closed-source software by having **the ability to identify issues quickly and addressing them as soon as possible.**
-
-Not just limited to more developers, often enterprises get involved with open-source projects that they utilize. And when they do, they will also go through the code and review it.
-
-This gives another source of external audit that may help improve the security of the software.
-
-In contrast, with a closed-source software, a limited number of developers may not be able to find all kinds of security issues. And it may take them longer to fix all the issues one by one.
-
-#### Community Decision Making to Prioritize Security Issues
-
-The developers of a closed-source software may have certain restrictions and priorities as what to work on and when to resolve an issue.
-
-However, in case of an open-source project, the community of contributors can prioritize and assign themselves what they want to work on and when to fix an issue. You do not need to depend on a vendor or follow their instructions to address a security issue.
-
-The decision making that goes into addressing and fixing the security issues is more transparent and flexible in case of an open-source software. Hence, it can prove to be more effective leaving you with three specific benefits:
-
- * **Transparency**
- * **No dependency on the vendor**
- * **Faster security updates**
-
-
-
-### Open Source Software is not Bulletproof: Here’s Why
-
-![][3]
-
-While there are cases where open-source software may get an edge for security, there could be instances or factors that affects it.
-
-It is important to acknowledge that these problems exist, accordingly, an enterprise or an individual can make better decision about the state of security for an open-source software.
-
-#### Not enough Eyes to Review Code and Uncertainty
-
-Even if the code is accessible the world of developers, there are chances that a **project does not have enough contributors/developers to thoroughly review the code**.
-
-In that case, we cannot have great confidence of an open-source software being peer-reviewed, because it lacks exactly that.
-
-The open-source software may “claim” to have the best security just because its open-source, which is misleading when there are not enough developers working on it.
-
-Also, we do not know how many developers are looking/reviewing the code and how exactly the code walkthrough is going on.
-
-For instance, the Heartbleed bug was spotted after 2 years of its introduction in a project that was already popular i.e **OpenSSL**.
-
-#### Software Responsibility or Accountability
-
-This may not be important for individuals, but an **open-source software often comes with no warranties**.
-
-So, if a business uses it, they must take the responsibility of any losses or damages caused by the use of that software.
-
-This is something that tells you that nothing can be 100% secure and bug-free. No matter how many eyes you have on a code, or how skilled the contributors are, there will be risks in some form, be it security or data loss.
-
-And this brings us to the fact that open-source software is not bulletproof.
-
-### Open Source May Have its Edge for Better Security But…
-
-Nothing is superior when it comes to security. No matter if it is closed-source or open-source, the same set of principles apply when it comes to security.
-
-There are various external factors that can affect the security of a software, and **many of those are not source dependent**.
-
-The code must be monitored in the same way to keep things secure.
-
-Yes, the **open-source approach introduces benefits that closed-source software will never have**, but that does not mean that it is bulletproof.
-
-_What do you think about the state of security when it comes to open-source software?_ _Do you think it is superior to proprietary solutions?_

-Our open source startup journey
-======
-
-[ToolJet][1] is an open source, low-code framework for rapidly building and deploying internal tools. Our codebase is 100% JavaScript and TypeScript.
-
-A lone developer in April 2021 started ToolJet. The public beta launched in June 2021 and was an instant hit. With this traction, ToolJet raised funding, and currently, we have a team of 20 members.
-
-### Why open source?
-
-Before working on ToolJet, I worked with a few enterprise clients as a consultant. Many of these clients were large enough to build and maintain dozens of internal tools. Despite the constant requests from sales, support, and operations teams to add more features and fix the bugs in their internal tools, engineering teams struggled to find the bandwidth to work on the internal utilities.
-
-I tried using a few platforms to build and maintain internal tools. Most of these tools were very expensive, and frequently, they didn't really fit the requirements. We needed modifications, and most utilities didn't support on-premise hosting.
-
-As a Ruby developer, I primarily used ActiveAdmin and RailsAdmin to build internal tools. Both utilities are amazing, but making them work with more than one data source is difficult. I then realized there is a need in the market for a framework that could build user interfaces and connect to multiple data sources. I believe any tool built for developers should be open source. Most of the tools and frameworks that developers use daily result from people from all over the world collaborating in public.
-
-### The first commit
-
-Building something like ToolJet needed a full-time commitment. Selling one of my side projects gave me a runway of 5-6 months, and I immediately started working on an idea I'd had in mind for at least two years.
-
-The first commit (rails new) of ToolJet was on April 1, 2021.
-
-Wait! I said the codebase is 100% JavaScript. Continue reading to discover why.
-
-### Building and pitching investors
-
-I sat in front of my screens for most of April and May, coding and pitching to investors for a pre-seed round.
-
-My work also included creating the drag-and-drop application builder, documenting everything, ensuring there was documentation for setting ToolJet up on popular platforms, creating a website, creating posters and blog posts for launch, and more. The process went well without any major challenges. At this point, the frontend of ToolJet was built using React, with the backend using Ruby on Rails.
-
-While the coding was going well, investor pitches weren't going great. I sent around 40 cold emails to venture capitalist firms and "angel investors" focused on early-stage funding. While most of them ignored the email, some shared their reason for rejection, and some scheduled a call.
-
-Most of the calls were the same; I couldn't convince them of an open source business model.
-
-### The launch
-
-June 7th was the day of the launch. First, we launched on ProductHunt. Six hours passed, and there were only 70 new signups. But we were trending as the #1 product of the day (and ended up as the #3 product of the week). For posterity, here's the original [post][2].
-
-I also posted on [HackerNews][3] around 6 PM, and within an hour, the post was #1. I was very happy that many visitors signed up and starred the repository. Many of these visitors and users reported bugs in the application and documentation. Within eight hours of posting on HN, more than 1,000 GitHub users starred ToolJet's GitHub repository, and there were hundreds of signups for ToolJet cloud. The trend continued for three days, and the repo had 2.4k stars.

-
-### Getting funding
-
-The traction on GitHub was enough to be noticed by the venture capitalist (VC) world. The days following the launch were packed with calls. We had other options, but did not consider seriously consider them, including:
-
-- Bootstrapping: During the early stages of the product, it was hard to find paying customers, and I did not have enough savings to fund the project until that happened.
-- Building as a side project: While this strategy works great for smaller projects, I didn't feel it would work for ToolJet because we needed to create dozens of integrations and UI widgets before the platform could become useful for customers. As a side project, it might take months or years to achieve that.
-
-I knew it could take months to build the platform I wanted if ToolJet became just a side project. I wanted to accelerate growth by expanding the team, and VC funding was the obvious choice, given the traction.
-
-The good news is that we raised[$1.55 million in funding][5] within two weeks of the HN launch.
-
-### Stack matters in open source
-
-Soon after the launch, we found that many people wanted to contribute to ToolJet, but they were mostly JavaScript developers. We also realized that for a framework like ToolJet that in the future should have hundreds of data source connectors, only a plugin-based architecture made sense. We decided to migrate from Ruby to TypeScript in August 2021. Even though this took about a month and significant effort, this was one of the best decisions we've made for the project. Today, we have an extensible plugin-based architecture powered by our [plugin development kit][6]. We have contributions from over 200 developers. We've written extensively about this migration [here][7] and [here][8].
-
-### Launching v1.0
-
-Many users have been using ToolJet on production environments since August, and the platform did not show any stability or scalability issues. We were waiting to wrap up the developer platform feature before we called it v1.0. The ToolJet developer platform allows any JavaScript developer to build and publish plugins for ToolJet. Developers are now able to make connectors for ToolJet. Creating a ToolJet connector can take just 30 minutes, including integration tests.
-
-### Building a growing community
-
-![ToolJet star history][9]

-
-We didn't spend money on marketing. Most of our efforts in spreading the news about ToolJet have been writing about our learnings and being active in developer communities. We have a team of three members who take care of community queries.
-
-### The business model
-
-ToolJet won't be a sustainable business without a [commercial product][10] to pay the bills. We've built an enterprise edition of ToolJet, for which customers must pay. There's no limit on usage for the free community edition, and additional features in the enterprise edition are relevant only to large teams. We have very large companies as paying customers right now, but we haven't started monetizing ToolJet aggressively. We have enough money left in the bank to build an even better ToolJet, so our focus currently is on product improvement.
-
-### What's next?
-
-We frequently release better versions of ToolJet with the help of constant feedback and contributions from the open source community. Many major improvements and dozens of connectors and UI components are in progress. We're moving faster than ever towards our initial goal of being the open framework that can connect to hundreds of data sources and build even the most complicated user interfaces!

-Write documentation like you develop code
-======
-
-Don't want documentation to be an afterthought? Try a new approach.
-
-Many engineers and craftspeople are particular about their tools. To do a job well, you need the best tools and the skills to use them. The best tools in software development can be very powerful when applied to other kinds of digital creation. The [Docs as Code][1] approach is a great example. Docs as Code entails writing documentation using the same tools and workflows used for developing code. Proponents of Docs as Code report that this method leads to better documentation while easing the workload of the people who write it.
-
-### Text formats and source control
-
-The most significant adjustment when moving from a more traditional documentation platform to the Docs as Code approach is that the content is stored in a text-based markup format. This change makes all the tools for text-based materials available for generating documentation. Whether you choose [DocBook][2], [Markdown][3], or another markup language, the transition from using just one tool to using a standard format and a variety of tools is a big change.
-
-Finding tools that support your workflow is really important. Many developers use their [coding editors][4] when working on Docs as Code projects. Since they are already advanced-level users with that tool, it works well for them. Finding tooling that fits the other professionals on the team, such as technical writers, editors, information architects, and documentation product owners, may take more effort. A few options to consider:
-
-- One of the many [good markdown editors][5] available
-- Coding editors with good preview tools, which make them approachable for non-coders
-- The web interfaces of popular Git hosting services, especially for occasional contributors
-
-Once content is safely in a markup format, the project can use source control such as [Git][6], an open source tool with many more features than most documentation platforms can claim:
-
-- A clear and detailed version history of who changed what and when. If you have good commit message culture, you may even be able to learn why the change was made.
-- Easy parallel change processes. Working in branches in Git means everyone can make all the changes they want to and combine them at the end.
-- Advanced collaboration and review tooling. All the source-control platforms are designed to review each change in detail and have as much discussion as needed until everyone is confident that the change can go ahead.
-- Automated quality checks such as spellchecking and link checking. This saves time and catches errors that might otherwise be missed.
-
-Source control has many benefits. Just keep in mind that if you're new to source control, it has a learning curve. There are some excellent [learning resources][7] and [articles for writers][8] that can help. You can also let your curious documentarians find the learning materials that work for them rather than asking your engineers to teach them. (Ask me how I learned this—the hard way of course!)
-
-### Pull requests and review cycles
-
-All source-control platforms are designed around the concept of pull requests, sometimes also called merge requests. Someone, or some team, puts together a set of changes and then requests that the changes are pulled into the main project. In many ways, working with many changes at once is easier in documentation than in code. Changing one article in one place in documentation has fewer side effects than when you change code and find that there were several other sections depending on it.
-
-The most powerful collaboration tool is the [diff][9], which shows the difference between old and new versions in a way that's easy to follow. There are many versions of this tool available to make the comparison view easier to look at: side-by-side, inline, or even as rendered markdown rather than just text. Each team member can use the tool or tools that work best for them. For example, the web view is commonly used to look at a small change, but for something bigger I would want to look at it locally using `vimdiff` or [Meld][10].
-
-Review comments can be added to the change as a whole or to individual lines in the proposed change. Some projects adopt a maximum line length, called a hard wrap, or start each sentence on a new line to make it easier to attach comments to specific parts of a block of text. Further changes and comments can be added until the review process is complete and the change is accepted. Since the pull requests are shown in a queue on the repository for the project, this is a good way to show what's in progress and what needs review attention. The tools make it easy for reviewers to add their thoughts. In particular, if you are working with technical audiences it can be easier to get reviews from these folks via the tools they use daily.
-
-### Continuous integration and deployment
-
-Having the source of your documentation available in plain text has many benefits, such as making it easy to find every occurrence of something that needs changing and using existing tools such as [wc][11], [grep][12], or `tree` to work with potentially large document sets. When you combine this with a source-control platform, even more existing tools become available, and they're all open source.
-
-One big workflow improvement is the ability to have continuous deployment in place. This simply means that when a pull request is merged into the main project, the project is immediately and automatically deployed. If the change is good enough to be accepted into the project, it is also good enough to be live on the documentation site, helping your readers. Typically, continuous deployment is set up with either a separate automation server, such as [Jenkins][13], or [Git Hooks][14]. Either way, the text-based markup is combined with the Docs as Code platform (usually a static site generator such as [Hugo][15] or [Sphinx][16]) to produce the documentation website, which is then deployed.
-
-The same automation can be used before deployment to add some excellent checks to the pull requests before they are merged. On a coding project, it's common to run code linters, tests, and other quality checks that a machine can do itself. Documentation projects can get the same treatment, with tools like [Vale][17] to do prose linting and check for correct heading styles, spellings, and so on. It's also useful to add other tools here, such as a link checker to make sure all the links go somewhere valid.
-
-### Code tools for docs workflows
-
-The tools known and loved by engineers are very good tools, but they are useful for all sorts of other projects too. For documentation, they contribute valuable efficiency, especially when you need your documentation to be moving at the same speed as your development teams. All the tools discussed here are open source, so you can try them for yourself, deploy them for a huge global team, or anything in between. May your docs process be as smooth as any code process.

-8 ideas for measuring your open source software usage
-======
-
-Those of us who support open source project communities are often asked about usage metrics — a lot. The goal of these metrics is usually to demonstrate the software's importance as measured by its user base and awareness. We typically want to know: how many people use the software, how many installations are there, and how many lives are being touched.
-
-To make a long story short: We cannot answer these questions directly.
-
-Sorry to disappoint you if you were hoping for a definitive solution. No one has the perfect answers to questions about usage metrics. At least, no precise answers.
-
-The good news is that there are approximations and alternative metrics that can satisfy your thirst for knowledge about the software's usage, at least partially. This article explores these alternatives including their benefits and shortcomings.
-
-### Downloads
-
-When you visit websites that offer software, you can often see how many times the software has been downloaded. An example that comes to mind is Firefox, which used to have a download counter. It was an impressive number and gave the impression that Firefox was a popular browser—which it was for a while.
-
-However, individual behavior can directly impact the accuracy of this number. For example, when a person wipes their machine regularly, each rebuild incurs a separate download. To account for this reality, there needs to be a way to subtract a few dozen (maybe hundreds) downloads from the number because of that one person.
-
-Not only can downloads overestimate usage, but they can also underestimate usage. For instance, a system administrator may download a new version of Firefox once to a flash drive and then install it on hundreds of devices.
-
-Download metrics are easy to collect because you can log each download request on the server. The problem is that you don't know what happens to the software after it is downloaded. Was the person able to use the software as anticipated? Or did the person run into issues and abandon the software?
-
-For open source projects, you can consider a variety of download metrics, such as the number of binaries downloaded from:
-
-- the project website
-- package managers such as npm, PyPi, and Maven
-- code repositories like GitHub, GitLab, and Gitee
-
-You may also be interested in downloads of the source code because downstream projects are most likely to use this format (also read [How to measure the impact of your open source project][1]). Relevant download metrics include:
-
-- The number of clones (source code downloads) from code repositories like GitHub, GitLab, and Gitee
-- The number of archives (tar, zip) downloaded from the website
-- The number of source code downloads through package managers like npm, PyPi, and Maven
-
-Download metrics for source code are an even less reliable measure than binary downloads (although there is no research to demonstrate this). Just imagine that a developer wants to use the most recent version of your source code and has configured their build pipeline to always clone your repository for every build. Now imagine that an automated build process was failing and retrying to build, constantly cloning your repository. You can also imagine a scenario where the metric is lower than expected—say the repository is cached somewhere, and downloads are served by the cache.
-
-**[ Related read [5 metrics to track in your open source community][2] ]**
-
-In conclusion, download metrics are good proxies for detecting trends and providing context around current usage. We cannot define specifically how a download translates to usage. But we can say that an increase in downloads is an indicator of more potential users. For example, if you advertise your software and see that download numbers are higher during the campaign, it would be fair to assume that the advertisement prompted more people to download the software. The source and metadata of the download can also provide additional context for usage patterns. What versions of your software are still in use? What operating system or language-specific versions are more popular? This helps the community prioritize which platforms to support and test.
-
-### Issues
-
-As an open source project, you probably have an issue tracker. When someone opens an issue, two common goals are to report a bug or request a feature. The issue author has likely used your software. As a user, they would have found a bug or identified the need for a new feature.
-
-Obviously, most users don't take the extra step to file an issue. Issue authors are dedicated users and we are thankful for them. Also, by opening an issue, they have become a non-code contributor. They may become a code contributor. A rule of thumb is that for every 10,000 users, you may get 100 who open an issue and one who contributes code. Depending on the type of user, these ratios may differ.
-
-With regard to metrics, you can count the number of issue authors as a lower-bound estimation for usage. Related metrics can include:
-
-- The number of issue authors
-- The number of active issue authors (opened an issue in the last 6 months)
-- The number of issue authors who also contribute code
-- The number of issues opened
-- The number of issue comments written
-
-### User mailing lists, forums, and Q&A sites
-
-Many open source projects have mailing lists for users, a forum, and presence on a Q&A site, such as Stack Overflow. Similar to issue authors, people who post there can be considered the tip of the iceberg of users. Metrics around how active a community is in these mailing lists, forums, and Q&A sites can also be used as a proxy for increasing or decreasing the user base. Related metrics can focus on the activity in these places, including:
-
-- The number of user mailing list subscribers
-- The number of forum users
-- The number of questions asked
-- The number of answers provided
-- The number of messages created
-
-### Call-home feature
-
-To get accurate counts of users, one idea is to have your software report back when it is in use.
-
-This can be creepy. Imagine a system administrator whose firewall reports an unexpected connection to your server. Not only could the report never reach you (it was blocked), but your software may be banned from future use.
-
-Responsible ways to have a call-home feature is an optional service to look for updates and let the user know to use the latest version. Another optional feature can focus on usage telemetry where you ask the user whether your software may, anonymously, report back how the software is used. When implemented thoughtfully, this approach can allow users to help improve the software by their style of using it. A user may have the opinion: "I often don't allow this usage information sharing but for some software I do because I hope the developers will make it better for me in the long term."
-
-### Stars and forks
-
-Stars and forks are features on social coding platforms like GitHub, GitLab, and Gitee. Users on these platforms can star a project. Why do they star projects? GitHub's documentation explains, "You can star repositories and topics to keep track of projects you find interesting and discover related content in your news feed." Starring is the equivalent of bookmarking and also provides a way to show appreciation to a repository maintainer. Stars have been used as an indicator of the popularity of a project. When a project has a big announcement that attracts considerable attention, the star count tends to increase. The star metric does not indicate the usage of the software.
-
-Forks on these social coding platforms are clones of a repository. Non-maintainers can make changes in their fork and submit them for review through a pull request. Forks are more a reflection of community size than stars. Developers may also fork a project to save a copy they can access even after the original repository has disappeared. Due to the use of forks in the contribution workflow, the metric is a good indicator for the developer community. Forks do not typically indicate usage by non-developers because non-developers usually do not create forks.
-
-### Social media
-
-Social media platforms provide gathering places for people with shared interests, including Facebook, Instagram, LinkedIn, Reddit, Twitter, and more. Using a social media strategy, open source projects can attract people with interest and affinity for their projects by setting up respective gathering spaces on these platforms. Through these social media channels, open source projects can share news and updates and highlight contributors and users. They can also be used to meet people who would not otherwise interact with your project.
-
-We are hesitant to suggest the following metrics because they have no clear connection to actual usage of your software and often require analysis for positive, negative, and neutral sentiment. People may be excited about your project for many different reasons and want to follow it without actually using it. However, like other metrics already discussed, showing that you are able to draw a crowd in social media spaces is an indicator of the interest in your project overall. Metrics for different social media platforms may include:
-
-- The number of followers or subscribers
-- The number of messages
-- The number of active message authors
-- The number of likes, shares, reactions, and other interactions
-
-### Web analytics and documentation
-
-Website traffic is a useful metric as well. This metric is influenced more by your outreach and marketing activities than your number of users. However, we have an ace up our sleeve: our user documentation, tutorials, handbooks, and API documentation. We can see what topics on our website draw attention, including documentation. The number of visitors to the documentation would arguably increase with an increase in the number of discrete users of the software. We can therefore detect general interest in the project with visitors to the website and more specifically observe user trends by observing visitors to the documentation. Metrics may include:
-
-- The number of website visitors
-- The number of documentation visitors
-- The duration visitors spend on your website or in documentation
-
-### Events
-
-Event metrics are available if you are hosting events around your project. This is a great way to build community. How many people submit abstracts to speak at your events? How many people show up to your events? This can be interesting for both in-person and virtual events. Of course, how you advertise your event strongly influences how many people show up. Also, you may co-locate your event with a larger event where people travel anyway, and thus, are in town and can easily attend your event. As long as you use a consistent event strategy, you can make a case that a rise in speaker submissions and attendee registrations are indicative of increasing popularity and user base.
-
-You don't need to host your own event to collect insightful metrics. If you host talks about your project at open source events, you can measure how many people show up to your session focused on your project. At events like FOSDEM, some talks are specifically focused on updates or announcements of open source projects and the rooms are filled to the brim (like almost all sessions at FOSDEM).
-
-Metrics you might consider:
-
-- The number of attendees at your project-centric event
-- The number of talks submitted to your project-centric event
-- The number of attendees at your project-centric talks
-
-### Conclusion about approximating usage of open source software
-
-As we've illustrated, there are many metrics that can indicate trends around the usage of your software, and all are imperfect. In most cases, these metrics can be heavily influenced by individual behavior, system design, and noise. As such, we suggest that you never use any of these metrics in isolation, given the relative uncertainty of each one. But if you collect a set of metrics from a variety of sources, you should be able to detect trends in behavior and usage. If you have the means to compare the same set of metrics across multiple open source projects with commonalities—such as similar functionality, strong interdependencies, hosted under the same foundation, and other characteristics—you can improve your sense of behavioral baselines.
-
-Note that in this overview, we've also chosen to highlight metrics that evaluate direct usage. As most software depends on a variety of other software packages, we would be remiss if we did not mention that usage and behavior can also be heavily impacted by indirect usage as part of a dependency chain. As such, we recommend incorporating the count of upstream and downstream dependencies as another layer of context in your analysis.
-
-In closing, as the wielder of data and metrics, we encourage you to recognize the power and responsibility that you have for your stakeholders. Any metric that you publish has the potential to influence behavior. It is a best practice to always share your context—bases, sources, estimations, and other critical contextual information—as this will help others to interpret your results.
-
-We thank the CHAOSS Community for the insightful conversation at CHAOSScon EU 2022 in Dublin, Ireland that sparked the idea for this blog post and to the CHAOSS Community members who reviewed and helped improve this article.

-How open principles will impact the future of work
-======
-In many ways, the nature of our work defines us. So how do we prepare
-for a future when the nature of work will change dramatically?
-![Working on a team, busy worklife][1]
-
-If we define "work" as any contribution that receives any kind of reward, then work is—and always has been—one of the major factors that define who we are. It is a major aspect of our lives. Throughout our work (whatever that may be for us), we meet friends, identify sources of intellectual stimulation and emotional fulfillment, grow, and feel at our most creative and innovative. To our families, friends, communities and societies, work is extremely important. We should not take work—or its role in our lives—lightly or for granted.
-
-So if the [nature of work is going to change][2] in the future, it might mean that something key to our very sense of _self_ is going to change. And we should plan for those changes very seriously.
-
-Consider the transformation of work throughout the Industrial Revolution (between the 1700s and 1800s). It drove many people from rural farm work into factories in the cities, fundamentally altering their lifestyles. It required new, more specialized skills (rather than the kind of artisanship common in rural economies). As we examine our own personal work environments in the decades to come, we'll see a potential reversal of the trends we saw during the Industrial era: from hierarchy and interchangeable general skills and activities to the reinstatement of horizontal collaboration and more specialized mastery (back to artisanship).
-
-This time, though, these changes come on a global scale rather than a local one, and the speed of change is far more accelerated.
-
-And in this new work environment, [open organization principles][3] will play a vital role.
-
-In this series, I'll review [_The Shift_, a book by Professor Lynda Gratton][4]—a book that, while written in 2014 from data assembled in 2010, still rings true today (and will in the future, too). In this book, Gratton projects how work will change around 2025 and 2050. This is vital information, as it will help us make sound choices when preparing for and developing our careers moving forward.
-
-Gratton explains predominant forces influencing the future of work in this timeframe. In this article series, I'll summarize them—and explain how open organization principles are involved in each.
-
-### Five factors influencing the future of work
-
-Driving the Industrial Revolution were inventions that used coal and steam power. Today, [Gratton][5] says, five subtle forces are causing a similar "shift":
-
- 1. increased global activities
- 2. rapid advances in technology
- 3. human longevity and demographics
- 4. societal and family structural changes
- 5. the need for a low-carbon economy
-
-
-
-In short: Computers will become faster. Materials will become stronger. Medicines will cure more diseases allowing longer human life. To varying degrees, these will all impact on how we work in the future. Here are a few notes on each.
-
-#### 1\. Globalization
-
-In a previous article, "[Globalization: A history of openness][6]," I discussed multiple forces and factors related to globalization, one of them being trade. Between 1950 and 2010 the volume of global trade has increased by 60 times, while at the same time transportation costs have fallen. And at the same time, developing countries are seeing not only increased trade but new innovations. I also discussed globalization in early history as part of my article "[Open organizations through the ages][7]." And I explored the importance of global governance—both now and into the future—in my article ["What would a global open organization look like?"][8] According to Gratton, globalization will have an undeniable and unavoidable impact on the future work.
-
-If the nature of work is going to change in the future, it might mean that something key to our very sense of self is going to change. And we should plan for those changes very seriously.
-
-#### 2\. Technology
-
-The cost of computing has been coming down at an alarming rate. And it will continue to decrease. This will help connect billions of people that have been mostly left out of the greater global economy until now. They will start to both enter the workforce and become more influential consumers. At the same time, computers and advanced automation [will replace jobs performed by humans][9] in the future. This all will influence work shifts in the future.
-
-#### 3\. Demographics and longevity
-
-Gratton also notes the impacts that various generations will have on the future of work, particularly in the United States. Younger generations will play a major role in the future, as their attitudes are different from earlier generations. Moreover, birth rates in various global regions will have an impact on prosperity. There will be more migration, as some regions' populations will decline while others increase. They will move to what Professor Gratton calls "creative clusters." And finally, Gratton argues, the life expectancy globally will change. By 2025, 10% of the world's population will be over the age of 65. These people will more than likely want to continue to work for sustained income, continued mental stimulation, physical activity, connection to others, and a source of meaning and purpose in their lives. Also, consider that many children today will more than likely live longer than 100 years. If they retired at 65 years old, they would have 35 years to do very little. With that thought in mind, having several career changes and being active in volunteer and community service programs in the future will expand greatly.
-
-#### 4\. Society
-
-In addition to the generational changes, Gratton notes several important social changes, too. There will be changing roles of women in the workplace, she says. People will have more choices to form the life they want than ever before. And with increased productivity per person, there will be more average free time available than ever before, she writes.
-
-#### 5\. Energy resources
-
-I've talked about the expansion of resource-saving industries in a presentation I've given on "[The Resource Industrial Revolution][10]." Gratton adds valuable points to this conversation. Climate change, she notes, will gradually become a major issue, which will reduce transportation and consumption. In particular, global water supply will not be able to keep pace with demand. Water desalination projects will expand greatly (possibly powered by [Generation IV][11] distributed small modular nuclear power plants (SMR's) now being developed). Environmental catastrophes will displace people and migration will create displaced communities throughout the globe. More energy-efficient ways of living will be discovered and introduced. This will influence future jobs.
-
-### Preparing for the future
-
-These five forces will prompt fundamental changes to the way we work in the future, Gratton argues. But we need to begin preparing for that future now. In the next article of this series, I'll explain Gratton's outlook and a few scenarios for grappling with a rapidly changing future. How could a person look at those changes as career opportunities? On the other hand, what would happen if a person simply _ignored_ those changes to come? I'll review Gratton's thoughts on those questions. Also, I'll also explain how open principles can form the heart of necessary changes.

-Open source game achievements
-======
-
-![][1]

-
-Learn how Gamerzilla brings an achievement system to open source games and enables all developers to implement achievements separate from the game platform.
-
-Some open source games rival the quality of commercial games. While it is hard to match the quality of triple-a games, open source games compete effectively against the indie games. But, gamer expectations change over time. Early games included a high score. Achievements expanded over time to promote replay. For example, you may have completed a level but you didn’t find all the secrets or collect all the coins. The Xbox 360 introduced the first multi-game online achievement system. Since that introduction, many game platforms added an achievement system.
-
-Open source games are largely left out of the achievement systems. You can publish an open source game on Steam, but it costs money and they focus on working with companies not the free software community. Additionally, this locks players into a non-free platform.
-
-Commercial game developers are not well served either, since some players enjoy achievements and refuse to purchase from other stores due to the inability to share their accomplishments. This lock-in gives the power to the platform holder. Each platform has a different system forcing the developer to implement support and testing multiple times. Smaller platform are likely to be skipped entirely. Furthermore, the platform holder has access to the achievement data on all companies using their system which could be used for competitive advantage.
-
-### Architecture of Gamerzilla
-
-[Gamerzilla][4] is an open source game achievement system which attempts to correct this situation. The design considered both open source and commercial games. You can run your own Gamerzilla server, use one provided by a game store, or even distributions, or other groups could run them. Where you buy the game doesn’t matter. The achievement data uploads to your Gamerzilla server.
-
-Game achievements require two things, a game, and a Gamerzilla server. As game collections grow, however, that setup has a disadvantage. Each game needs to have credentials to upload to the Gamerzilla server. Many gamers turn to game launchers due to their large number of games and ability to synchronize with one or more stores. By adding Gamerzilla support to the launcher, the individual games no longer need to know your credentials. Session results will relay from the game launcher to the Gamerzilla server.
-
-At one time, freegamedev.net provided the Hubzilla social networking system. We created an addon allowing us to jump start Gamerzilla development. Unfortunately server upgrades broke the service so freegamedev.net stopped offering it.
-
-For Gamerzilla servers, two implementations exist. Maintaining Hubzilla is a complex task, so we developed a standalone Gamerzilla service using *.*Net and React. The API used by games remains the same so it doesn’t matter which implementation you connect to.
-
-Game launchers development and support often lags. To facilitate adding support, we created libgamerzilla. The library handles all the interaction between the game launcher, games, and the Gamerzilla server. Right now only _GameHub_ has an implementation with Gamerzilla support and merging into the project is pending. On Fedora Linux, libgamerzilla-server package serves as a temporary solution. It does not launch games but listens for achievements and relays them to your server.
-
-Game support continues growing. As with game launchers, developers use libgamerzilla to handle the Gamerzilla integration. The library, written in C, is in use in a variety of languages like Python and nim. Games which already have an achievement system typically take only a few days to add support. For other games ,collecting all the information to award the achievements occupies the bulk of the implementation time.
-
-### Setting up a server
-
-The easiest server to setup is the Hubzilla addon. That, however, requires a working Hubzilla site which is not the simplest thing to setup. The new .Net and React server can be setup relatively easily on Fedora Linux, although there are a lot of steps. The [readme][5] details all the steps. The long set of steps is, in part, due to the lack of a built release. This means you need to build the .Net and the React code. Once built, React code serves up directly in Apache. A new service runs the .Net piece. Apache proxies all requests to the Gamerzilla API for the new service.
-
-With the setup steps done, Gamerzilla runs but there are no users. There needs to be an easy way to create an administrator and register new users. Unfortunately this piece does not exist yet. At this time, users must be entered directly using the sqlite3 command line tool. The instructions are in the [readme][5]. Users can be publicly visible or not. The approval flag allows new users to not use the system immediately but web registration still needs to be implemented The user piece is designed with replacement in mind. It would not be hard to replace backend/Service/UserService.cs to integrate with an existing site. Gaming web sites could use this to offer Gamerzilla achievements to their users.
-
-Currently the backend uses a sqlite database. No performance testing has been done. We expect that larger installations may need to modify the system to use a more robust database system.
-
-### Testing the system
-
-There is no game launcher easily available at the moment. If you install libgamerzilla-server, you will have the command _gamerzillaserver_ available from the command line. The first time you run it, you enter your url and login information. Subsequent executions will simply read the information from the configuration file. There is currently no way to correct a mistake except deleting the file at _.local/share/ga_merzillaserver/server.cfg and running _gamerzillaserver_ again.
-
-Most games have no built releases with Gamerzilla support. [Pinball Disc Room on itch.io][6] does have support built in the Linux version. The web version has no achievements There are only two achievements in the game, one for surviving for ten seconds and the other for unlocking and using the tunnel. With a little practice you can get an achievement. You need to check your Gamerzila server as the game provides no visual notification of the achievement.
-
-Currently no game packaged in Fedora Linux supports Gamerzilla. SuperTuxKart merged support but is still awaiting a new release. Seahorse adventures and Shippy 1984 added achievements but new releases are not packaged yet. Some games with support, we maintain independently as the developers ignore pull requests or other attempt to contact them.
-
-### Future work
-
-Gamerzilla needs more games. A variety of games currently support the system. An addition occurs nearly every month. If you have a game you like, ask the developer to support Gamerzilla. If you are making a game and need help adding support, please let us now.
-
-Server development proceeds at a slow pace and we hope to have a functional registration system soon. After that we may setup a permanent hosting site. Right now you can see our [test server][7]. Some people expressed concern with the .Net backend. The API is not very complex and could be rewritten in Python fairly easily.
-
-The largest unknown remains game launchers. GameHub wants a generic achievement interface. We could try to work with them to get that implemented. Adding support to the itch.io app could increase interest in the system. Another possibility is to do away with the game launcher entirely. Perhaps adding something like the gamerzillaserver to Gnome might be possible. You would then configure your url and login information on a settings page. Any game launched could then record achievements.

-Create a timer on Linux
-======
-A tutorial showing how to create a POSIX-compliant interval timer.
-![Team checklist][1]
-
-The timing of certain events is a common task for a developer. Common scenarios for timers are watchdogs, cyclic execution of tasks, or scheduling events for a specific time. In this article, I show how to create a POSIX-compliant interval timer using [timer_create(...)][2].
-
-You can download the source code for the following examples from [GitHub][3].
-
-### Prepare Qt Creator
-
-I used [Qt Creator][4] as the IDE for this example. To run and debug the example code in Qt Creator, clone the [GitHub][3] repository, open Qt Creator, and go to **File -> Open File or Project...** and choose the **CMakeLists.txt**:
-
-![Qt Creator open project][5]
-
-Open a project in Qt Creator (CC-BY-SA 4.0)
-
-After selecting the toolchain, click on **Configure Project**. The project contains three independent examples (we will only cover two of them in this article). With the green-marked menu, switch between the configurations for each example and activate **Run in terminal** for each of them (see the yellow mark below). The currently active example for building and debugging can be selected over the **Debug** button on the bottom left corner (see the orange mark below):
-
-![Project configuration][6]
-
-Project configuration (CC-BY-SA 4.0)
-
-### Threading timer
-
-Let's take a look at the _simple_threading_timer.c_ example. This is the simplest one: It shows how an interval timer is created, which calls the function **expired** on expiration. On each expiration, a new thread is created in which the function **expiration** is called.
-
-
-```
-#include <stdio.h>
-#include <stdlib.h>
-#include <time.h>
-#include <signal.h>
-#include <unistd.h>
-#include <string.h>
-#include <errno.h>
-
-void expired(union sigval timer_data);
-
-pid_t gettid(void);
-
-struct t_eventData{
- int myData;
-};
-
-int main()
-{
- int res = 0;
- timer_t timerId = 0;
-
- struct t_eventData eventData = { .myData = 0 };
-
- /* sigevent specifies behaviour on expiration */
- struct sigevent sev = { 0 };
-
- /* specify start delay and interval
- * it_value and it_interval must not be zero */
-
- struct itimerspec its = { .it_value.tv_sec = 1,
- .it_value.tv_nsec = 0,
- .it_interval.tv_sec = 1,
- .it_interval.tv_nsec = 0
- };
-
- [printf][7]("Simple Threading Timer - thread-id: %d\n", gettid());
-
- sev.sigev_notify = SIGEV_THREAD;
- sev.sigev_notify_function = &expired;
- sev.sigev_value.sival_ptr = &eventData;
-
- /* create timer */
- res = timer_create(CLOCK_REALTIME, &sev, &timerId);
-
- if (res != 0){
- [fprintf][8](stderr, "Error timer_create: %s\n", [strerror][9](errno));
- [exit][10](-1);
- }
-
- /* start timer */
- res = timer_settime(timerId, 0, &its, NULL);
-
- if (res != 0){
- [fprintf][8](stderr, "Error timer_settime: %s\n", [strerror][9](errno));
- [exit][10](-1);
- }
-
- [printf][7]("Press ETNER Key to Exit\n");
- while([getchar][11]()!='\n'){}
- return 0;
-}
-
-void expired(union sigval timer_data){
- struct t_eventData *data = timer_data.sival_ptr;
- [printf][7]("Timer fired %d - thread-id: %d\n", ++data->myData, gettid());
-}
-```
-
-The advantage of this approach is its small footprint, in terms of code and simple debugging. The disadvantage is the additional overhead due to the creation of a new thread on expiration and, consequently, the less deterministic behavior.
-
-### Interrupt Signal Timer
-
-Another possibility to be notified by an expired timer is based on a [kernel signal][12]. Instead of creating a new thread each time the timer expires, the kernel sends a signal to the process, the process is interrupted, and the corresponding signal handler is called.
-
-As the default action when receiving a signal is to terminate the process (see [signal][13] man page), we have to prepare Qt Creator in advance so that properly debugging is possible.
-
-The default behavior of Qt Creator when the debuggee receives a signal is:
-
- * Interrupt execution and switch to the debugger context.
- * Display a pop-up window that notifies the user about the reception of a signal.
-
-
-
-Both actions are not wanted as the reception of a signal is part of our application.
-
-Qt Creator uses GDB in the background. In order to prevent GDB from stopping the execution when the process receives a signal, go to **Tools** -> **Options**, select **Debugger**, and navigate to **Locals & Expressions**. Add the following expression to _Debugging Helper Customization_:
-
-
-```
-`handle SIG34 nostop pass`
-```
-
-![Signal no stop with error][14]
-
-Sig 34 no stop with error (CC-BY-SA 4.0)
-
-You can find more information about GDB signal handling in the [GDB documentation][15].
-
-Next, we want to suppress the pop-up window that notifies us every time a signal is received when we stop in the signal handler:
-
-![Signal 34 pop up box][16]
-
-Signal 34 pop-up box (CC-BY-SA 4.0)
-
-To do so, navigate to the tab **GDB** and uncheck the marked checkbox:
-
-![Timer signal windows][17]
-
-Timer signal windows (CC-BY-SA 4.0)
-
-Now you can properly debug the _signal_interrupt_timer_. The actual implementation of the signal timer is a bit more complex:

-
-In contrast to the threading timer, we have to initialize the signal and register a signal handler. This approach is more performant as it won't cause the creation of additional threads. For this reason, the execution of the signal handler is also more deterministic. The drawback is clearly the extra configuration effort to debug this properly.
-
-### Summary
-
-Both methods described in this article are close-to-the-kernel implementations of timers. Even if the [timer_create(...)][2] function is part of the POSIX specification, it is not possible to compile the sample code on a FreeBSD system due to small differences in data structures. Besides this drawback, such an implementation gives you fine-grained control for general-purpose timing applications.

-WiFi 6 Promises Much More than Faster Speeds
-======
-WiFi 6 increases the network connectivity, and has been developed to ensure the trillions of devices connected in the near future continue to work seamlessly and efficiently. Though it was certified in 2019, it faced a few challenges in testing due to the pandemic. This article gives an overview of this technology.
-
-![WiFi-6][1]
-
-The next-generation standard in WiFi technology, termed ‘WiFi 6’, is also known as ‘AX WiFi’ or ‘802.11ax’. Developed to meet the exponential increase in demand for devices in the world, it can be used for virtual reality (VR) and smart home devices as well. It is an improvement on the current 802.11ac WiFi standard and meets current challenges in terms of capacity, efficiency, coverage and performance.
-
-![Figure 1: WiFi 6][2]
-
-Researched in 2014, this standard was invented in 2018 and launched by the IEEE High Efficiency WLAN Study Group (HEW SG). It began certifications in late 2019, with Samsung’s Galaxy Note 10 and Ruckus R750 employing this technology. Specified to operate between the 1GHz and 6GHz bands, WiFi 6 focuses mainly between the 2.4GHz and 5GHz frequencies.
-
-In an average household today, nine devices are connected to WiFi. WiFi 6 aims at improving the network rather than boosting the speed for individual devices.
-
-### Features of WiFi 6
-
-**Multi-user, multi-input, multi-output (MU-MIMO):** This communication between routers and multiple devices concurrently. It supports four simultaneous data streams, added to which one user can have a considerable bandwidth of incoming data from a smart router, both on the 2.4GHz and 5GHz frequencies.
-**1024-QAM:** This helps WiFi 6 encode more bits per packet. There is a 25 per cent increase in throughput. Not only does it improve efficiency in high-traffic situations, it also maximises data rates. This is a huge advantage for modern enterprise applications.
-**Orthogonal frequency-division multiplexing (OFDM):** This allows four times as many subcarriers and increases speed by 11 per cent. The expanded signal allows for greater simultaneous packet delivery across users. Hence, the wait time between packets and latency is reduced.
-*Increased channel width:* The 160MHz channel communication is added to the 80MHz band, thus doubling the channel width. This allows routers to handle more users and provide larger streams per user.
-*Target wake time (TWT):* This feature is unique to WiFi 6. It allows each device to independently negotiate wake time for transmission and reception. This helps to increase total sleep time and maximise battery life. TWT enables many additional networking options, especially for IoT devices.
-*Improved security:* All WiFi 6 devices will need to include Wi-Fi Protected Access 3 (WPA3). This will lead to encryption of unauthenticated traffic, robust password protection against brute-force dictionary attacks, and superior data reliability for sensitive information with 192-bit encryption.
-*Beamforming:* With eight support antennas, beamforming helps to improve data rates, and the range is extended by directing signals towards specific clients at once. It offers a backup for rapidly moving devices that may face issues with MU-MIMO. Beamforming also helps to control transmissions from antennas that cause signals to interfere on purpose. The signal can then be redirected to a new direction.
-
-### Devices that support WiFi 6
-
-Until recently, WiFi 5 was the standard used for routers, repeaters, mesh networks and many WiFi clients. WiFi 6 was launched in 2019. There will be some compatibility issues for the earlier devices that supported WiFi 5 — they will be able to utilise the WiFi 6 network but not be able to receive support for the same.
-
-WiFi 6 routers are backward-compatible, and it is better to make sure that the network is ready for that.
-
-WiFi 6 enables lower battery consumption, making it a great choice for any environment, including the Internet of Things (IoT). It reduces unnecessary data activity, and tells devices when to put their data to sleep and when to be active. As a result, unnecessary data activity is reduced, and performance and battery life are maximised.
-
-The Samsung Galaxy Note 10 and Ruckus R750 were the world’s first smartphone and access point certified to support Wi-Fi 6, with the latest generation of the Apple iPhone following suit. The Wi-Fi Alliance has set up its certification programme, and new wireless products hitting the market are expected to start applying for compliance certification. The devices listed below are already WiFi 6 enabled:
-
-* iPhone 11 and after
-* Samsung Galaxy S10, S20, Note 10, and Note 20
-* Apple computers with M1 processors
-* Smart TVs
-
-> To take advantage of the improvements in the 802.11ax standard fully, both hardware and software functionalities have to be built on this WiFi technology.
-
-### Hardware testing
-
-To unlock the full potential of the latest devices, a WiFi 6 router is needed to run the network. This was an expensive affair a few years ago, but now we have a number of options even for mesh systems, gaming routers, range extenders, and more. The best purchase can be made only when hands-on testing is done. Beating all its competitors, the current king in terms of speed for WiFi 6 routers is TP-Link Archer AX6000. This router was able to transmit data wirelessly at a rate of 1523 Mbps up to a distance of 1.5 metres (5 feet).
-
-One important thing to remember here is that these routers do not magically increase speeds. The theoretical maximum of achieving 9.6 Gbps is unlikely. This high theoretical speed can be split up across a whole network of devices.
-
-WiFi 6 emphasises quality connectivity in areas where connected devices are densely populated. It does not increase the speed of each device exponentially but ensures these operate at an optimum level.
-
-Only the combination of a faster plan from the Internet service providers (ISPs) along with the WiFi 6 router, can fulfil its true potential. The real challenge is for the ISPs, as they need new fibre rollouts to capitalise on this next-gen technology. An important question is: when faster ISP speeds come, will the existing hardware become redundant?
-
-### Applications of WiFi 6
-
-**Large public venues (LPVs):** Stadiums and convention centres are a few of the common areas where thousands of devices connect to WiFi at the same time. WiFi 6 can help to improve attendee experiences, increase customer interactions, and create value-added services like viewing instant replays or ordering food from one’s seat at an event. WiFi 6 allows LPV owners to create new business opportunities.
-**Transport hubs:** Public transport stations are also an area where people attempt to connect to the network simultaneously. OFDMA and BSS colouring in WiFi 6 provide the necessary tools needed to overcome this challenge.
-**IoT and smart city deployments:** Power efficiencies in WiFi 6 enable IoT devices to go into sleep mode and turn on their transmitters at predefined intervals to prolong field time without much maintenance.
-**Education:** Libraries, auditoriums, and lecture halls at college and university campuses have the highest density of WiFi users during the day, and almost no one at night. WiFi 6 is a perfect choice in this situation.
-
-### The challenges
-
-WiFi 6 does not promise an increase in speed, but is an upgrade designed to make sure the speeds of our devices within a given range/area doesn’t slow down a few years down the road. There are three major challenges it faces though, which are often overlooked.
-Improving the functionality of unsupported devices: Even though WiFi 6 is backward- compatible, justice to it can only be done when this technology is used to the maximum. This means devices need to be upgraded each time.
-
-Speed and performance outside the internal network: WiFi 6 can provide excellent connectivity for services like cloud file shares. However, the assets and resources of ISPs can affect speed and performance.
-
-*Coverage issues:* Transmission and bandwidths are capped according to the regulations prevalent in each country. Hence, the coverage of WiFi 6 may be restricted to ensure this cap is met.
-
-In spite of these challenges, companies like Aruba, Asus, AT&T, Boingo, Broadcom, Cisco, Comcast, CommScope, Cypress, Extreme Networks, Intel, Netgear, Orange, Qualcomm, TP-Link and Xiaomi are all focusing on the potential WiFi 6 has.

-Learn Rust by debugging Rust
-======
-Rustlings is an open source project by the Rust team that helps you learn Rust through the process of debugging.
-
-![Ferris the crab under the sea, unofficial logo for Rust programming language][1]
-
-Image by: Opensource.com
-
-In my previous [article about rustup][2], I showed you how to install the Rust toolchain. Well, what good is the toolchain if you won’t be using it to get more hands-on with Rust? Learning any language involves reading existing code and writing a lot of sample programs. That's a good way to become proficient in a language. However, there's a third way: debugging code.
-
-Learning through debugging involves trying to compile a pre-written (buggy) sample program, understanding the errors generated by the compiler, fixing the sample code, and then re-compiling it. Repeat that process until the code successfully compiles and runs.
-
-[Rustlings][3] is an open source project by the Rust team that helps you learn Rust through the process of debugging. It also provides you with a lot of hints along the way. If you're a beginner to Rust and have either started or completed reading the Rust book, then rustlings is the ideal next step. Rustlings helps you apply what you've learned from the book, and move to working on bigger projects.
-
-### Installing rustlings
-
-I'm using (and recommend) a Fedora machine to try rustlings, but any Linux distribution works. To install rustlings, you must download and run its install script. It's recommended that you do this as a normal user (not root) without any special privileges.
-
-Remember, for you to be able to use rustlings, you need the Rust toolchain available on your system. If you don't have that already, please refer to my [article on rustup][4].
-
-Once you're ready, download the installation script:
-
-```
-$ curl -L https://raw.githubusercontent.com/rust-lang/rustlings/main/install.sh > rustlings_install.sh
-$ file rustlings_install.sh
-rustlings_install.sh: Bourne-Again shell script, ASCII text executable
-```
-
-Inspect the script to learn what it does:
-
-```
-$ less rustlings_install.sh
-```
-
-And then run it to install:
-
-```
-$ bash rustlings_install.sh
-[...]
-Installing /home/tux/.cargo/bin/rustlings
-Installed package `rustlings v4.8.0 (/home/tux/rustlings)` (executable `rustlings`)
-All done!
-```
-
-Run 'rustlings' to get started.
-
-### Rustlings exercises
-
-The installation provides you with the `rustlings` command. Run it along with the `--help` flag to see what options are available.
-
-```
-$ rustlings --help
-```
-
-The installation script also clones the rustlings Git repository, and installs all the dependencies required to run the sample programs. You can view the sample programs within the exercises directory under `rustlings` :
-
-```
-$ cd rustlings
-$ pwd
-/home/tux/rustlings
-$ ls
-AUTHORS.md Cargo.toml CONTRIBUTING.md info.toml install.sh README.md target Cargo.lock CHANGELOG.md exercises install.ps1 LICENSE src tests
-$ ls -m exercises/
-advanced_errors, clippy, collections, conversions, enums, error_handling, functions, generics, if, intro, macros, mod.rs,
-modules, move_semantics, option, primitive_types, quiz1.rs, quiz2.rs, quiz3.rs, quiz4.rs, README.md,
-standard_library_types, strings, structs, tests, threads, traits, variables
-```
-
-### List all exercises from the command line
-
-The `rustlings` command provides you with a `list` command which displays each sample program, its complete path, and the status (which defaults to **pending**.)
-
-```
-$ rustlings list
-Name Path Status
-intro1 exercises/intro/intro1.rs Pending
-intro2 exercises/intro/intro2.rs Pending
-variables1 exercises/variables/variables1.rs Pending
-variables2 exercises/variables/variables2.rs Pending
-variables3 exercises/variables/variables3.rs Pending
-[...]
-```
-
-Near the end of the output, you're given a progress report so you can track your work.
-
-```
-Progress: You completed 0 / 84 exercises (0.00 %).
-```
-
-### View sample programs
-
-The `rustings list` command shows you what programs are available, so at any time you can view the code of those programs by copying the complete paths into your terminal as an argument for the [cat][5] or [less][6] commands:
-
-```
-$ cat exercises/intro/intro1.rs
-```
-
-### Verify your programs
-
-Now you can start debugging programs. You can do that using the `verify` command. Notice that rustlings chooses the first program in the list (`intro1.rs` ), tries to compile it, and succeeds:
-
-```
-$ rustlings verify
-Progress: [-----------------------------------] 0/84
-✅ Successfully ran exercises/intro/intro1.rs!
-
-You can keep working on this exercise,
-or jump into the next one by removing the `I AM NOT DONE` comment:
-
- 6 | // Execute the command `rustlings hint intro1` for a hint.
- 7 |
- 8 | // I AM NOT DONE
- 9 |
-```
-
-As you can see from the output, even though the sample code compiles, there's work yet to be done. Each sample program has the following comment in its source file:
-
-```
-$ grep "NOT DONE" exercises/intro/intro1.rs
-// I AM NOT DONE
-```
-
-Although the compilation of the first program worked fine, rustlings won't move to the next program until you remove the `I AM NOT DONE` comment.
-
-### Moving to the next exercise
-
-Once you have removed the comment from `intro1.rs`, you can move to the next exercise by running the `rustlings verify` command again. This time, you may notice that rustlings tries to compile the next program (`intro2.rs` ) in the series, but runs into an error. You're expected to debug that issue, fix it, and then move forward. This is a critical step, allowing you to understand why Rust says a program has bugs.
-
-```
-$ rustlings verify
-Progress: [>------------------------] 1/84
-⚠️ Compiling of exercises/intro/intro2.rs failed! Please try again. Here's the output:
-error: 1 positional argument in format string, but no arguments were given
- --> exercises/intro/intro2.rs:8:21
- |
-8 | println!("Hello {}!");
- | ^^
-
-error: aborting due to previous error
-```
-
-### Getting a hint
-
-Rustlings has a handy `hint` argument, which tells you exactly what's wrong with the sample program, and how to fix it. You can think of it as an add-on help option, in addition to what the compiler error message tells you.
-
-```
-$ rustlings hint intro2
-Add an argument after the format string.
-```
-
-Based on the above hint, fixing the program is easy. All you need to do is add an additional argument to the `println` statement. This diff should help you understand the changes:
-
-```
-< println!("Hello {}!", "world");
----
-> println!("Hello {}!");
-```
-
-Once you make that change, and removed the `NOT DONE` comment from the source code, you can run `rustlings verify` again to compile and run the code.
-
-```
-$ rustlings verify
-Progress: [>-------------------------------------] 1/84
-✅ Successfully ran exercises/intro/intro2.rs!
-```
-
-### Track progress
-
-You aren't going to finish all of the exercises in a day, and it's easy to lose track of where you left off. You can run the `list` command to see the status of your work.
-
-```
-$ rustlings list
-Name Path Status
-intro1 exercises/intro/intro1.rs Done
-intro2 exercises/intro/intro2.rs Done
-variables1 exercises/variables/variables1.rs Pending
-variables2 exercises/variables/variables2.rs Pending
-variables3 exercises/variables/variables3.rs Pending
-[...]
-```
-
-### Run specific exercises
-
-If you don't want to start from the beginning and skip a few exercises, rustlings allows you to focus on specific exercises using the `rustlings run` command. This runs a specific program without requiring the previous lesson to be verified. For example:
-
-```
-$ rustlings run intro2
-Hello world!
-✅ Successfully ran exercises/intro/intro2.rs
-$ rustlings run variables1
-```
-
-Typing exercise names can become tedious, but rustlings provides you with a handy `next` command so you can move to the next exercise in the series.
-
-```
-$ rustlings run next
-```
-
-### Alternative watch command
-
-If you don't want to keep typing `verify` after each modification you make, you can run the `watch` command in a terminal window, and then keep modifying the source code to fix issues. The `watch` command detects these modifications, and keeps re-compiling the program to see whether the issue has been fixed.
-
-```
-$ rustlings watch
-```
-
-### Learn by debugging
-
-The Rust compiler is known to provide very meaningful error messages, which helps you understand issues in your code. This usually leads to faster debugging. Rustlings is a great way to practice Rust, to get used to reading error messages, and understand the Rust language. Check out the recent features of Rustlings 5.0.0 on [GitHub][7].

-How to Record Streaming Audio in Ubuntu and other Linux Distributions
-======
-How to record audio in Ubuntu and other Linux distributions?
-
-If you want to record a voice over through the microphone of your computer, you can use GNOME Sound recorder or Audacity.
-
-Using GNOME Sound Recorder is easy but it lacks features. Audacity could be overwhelming initially but it has plenty of features for professional level recording. However, I am not going into that detail in this tutorial.
-
-GNOME Sound Recorder works with the microphone. There is another tool called Audio recorder and you can use it to record streaming music (from Sptify, YouTube, internet radio, Skype and most other sources) apart from microphone input.
-
-To summarize, I’ll show you the steps:
-
-* To record sound using GNOME Sound Recorder
-* To record streaming audio using Audio Recorder
-
-### Using Sound Recorder to record audio from the microphone
-
-GNOME desktop environment has a good variety of useful applications. Sound Recorder is one of them.
-
-You can install the [Sound Recorder][1] from the Ubuntu Software Center.
-
-![Sound Recorder can be installed from the Ubuntu Software Center][2]
-
-Or, you can use this command in the terminal to install it:
-
-```
-sudo apt install gnome-sound-recorder
-```
-
-Once installed, you can find it in the system menu and start from there.
-
-![GNOME Sound Recorder][3]
-
-Before you start using it, you should ensure that you have the correct input source chosen in the system settings. GNOME Sound Recorder
-
-![Ensure that you have chosen correct input in system settings][4]
-
-Once you open the Sound Recorder application, it will show an interface like the one below.
-
-![Hit the Record button to start audio recording][5]
-
-Hit on the record button and it starts recording audio instantly. While recording, you get options to pause, stop or discord the recording.
-
-![Options while recording audio][6]
-
-Your recordings are saved and available from the application interface itself. Click on the saved recordings to highlight it.
-
-You can replay the recordings or delete it. You can choose to save it to another location by clicking the save/download button. You may also rename the recordings using the edit button.
-
-![Saved recordings][7]
-
-That’s quite convenient, right? You can choose to record in MP3, FLAC and a couple of more formats.
-
-#### Removing GNOME Sound Recorder
-
-Don’t like it or find it lacking in terms of features?
-
-You can remove GNOME Sound Recorder from the Ubuntu Software Center or use the following command:
-
-```
-sudo apt remove gnome-sound-recorder
-```
-
-The application of GNOME Sound recorder is limited. It only records from the microphone and this is not what you would want in certain situations.
-
-Imagin you want to record a Skype call or something which is playing in an application or web browser? The nifty Audio Recorder helps in such cases.
-
-### Using Audio Recorder to record streaming audio
-
-You can watch this video to see how to use Audio Recorder. It’s a bit old but the steps are the same.
-
-![A Video from YouTube][8]
-
-[Subscribe to our YouTube channel for more Linux videos][9]
-
-You can use the [official PPA][10] to install Audio Recorder in Ubuntu and Linux Mint. Use the following commands in the terminal (Ctrl+Alt+T) one by one:
-
-```
-sudo apt-add-repository ppa:audio-recorder/ppa
-sudo apt update
-sudo apt install audio-recorder
-```
-
-Alternatively, you can download the source code from [launchpad][11]. Once installed, you can start the application from the Activity Overview:
-
-![Audio Recorder][12]
-
-#### Record all kinds of sound from various sources
-
-Audio Recorder records all kinds of sounds your computer makes.
-
-It records audio played through your system’s soundcard, microphones, browsers, webcams and more.
-
-In other words, it records even if your system sneezes (given that you want to record it). It allows you to select the recording device such as webcam, microphone, Skype, etc.
-
-To record the streaming music, select the appropriate source. For example, if you are playing streaming radio in Rhythmbox, then select Rythmbox.
-
-![Audio-Recorder Audio Settings][13]
-
-#### Record at your convenience
-
-Audio Recorder also gives you the option of setting timer. You can start, stop or pause recording at a given clock time or at a pre-defined interval. You can also set the limit on the recorded file size.
-
-Moreover, you can pause (and stop) when there is no audio (or very low sound) and resume it when sound comes back.
-
-All you have to do is to edit the text in the Timer panel. Comment out the “rules” you don’t want to apply and edit the ones per your requirement.
-
-![Audio-recorder Timer Settings][14]
-
-It provides additional settings like auto start at login, show tray icon and other record settings.
-
-![Audio-recorder Additional Settings][15]
-
-#### Save the recorded music file in various file formats
-
-Another gem. You can save the recorded file in your favourite file format. Supported file formats are OGG audio, Flac, MP3, SPX and WAV. I prefer MP3 for my recordings.
-
-The **recorded files are stored in ~/Audio** i.e., in the Audio folder inside your home directory.
-
-![Audio-recorder Audio Formats][16]
-
-#### How good is Audio Recorder?
-
-I used Audio Recorder in Ubuntu to [record the music played on YouTube][17]. I saved a 2-minute video in MP3 format that took 934 KB of space. But I must say I was not expecting the recorded sound quality to be so good. Honestly, I could not distinguish it from the original YouTube song.
-
-#### Removing Audio Recorder
-
-If you don’t find Audio Recorder to your liking, you can remove it using the following commands:
-
-```
-sudo apt remove audio-recorder
-```
-
-It will be a good idea to [remove the PPA as well][18]:
-
-```
-sudo apt-add-repository -r ppa:audio-recorder/ppa
-```
-
-### Conclusion
-
-There are probably several other tools for audio recording in Linux. Like GNOME, other desktop environments may also have sound recording apps. I know Deepin has one for sure.
-
-GNOME Sound Recorder is a decent tool for recording sound from your microphone. For recording sound from various sources, Audio Recorder is a good choice.
-
-I hope it helps with your audio recording needs. Let me know if you have any suggestions.

-Learn the OSI model in 5 minutes
-======
-Get the basics of the Open Systems Interconnection (OSI) framework for conceptualizing communication within a computer system.
-
-The Open Systems Interconnection (OSI) model is a standard for how computers, servers, and people communicate within a system. It was the first standard model for network communications and was adopted in the early 1980s by all major computer and telecommunications companies.
-
-The OSI model provides a universal language for describing networks and thinking about them in discrete chunks, or layers.
-
-### Layers of the OSI model
-
-The model describes the seven layers through which computer systems communicate over a network.
-
-1. [Application layer][2]
-2. [Presentation layer][3]
-3. [Session layer][4]
-4. [Transport layer][5]
-5. [Network layer][6]
-6. [Data link layer][7]
-7. [Physical layer][8]
-
-Each of these layers has its own way of working, with its own set of protocols that distinguish it from the others. This article provides a breakdown of the layers one by one.
-
-### Application layer
-
-The application layer is implemented in software. It is the layer used to interact with applications.
-
-Consider the example of sending a message. The sender will interact with the application layer and send the message. The application layer sends the message to the next layer in the OSI Model, the presentation layer.
-
-### Presentation layer
-
-The data from the application layer is forwarded to the presentation layer. The presentation layer receives the data in the form of words, characters, letters, numbers, and so on, and converts them into machine representable binary format. This process is known as translation.
-
-At this stage, ASCII characters (American Standard Code for Information Interchange) are converted into Extended Binary Coded Decimal Interchange Code (EBCDIC). Before the converted data goes further, it also undergoes encoding and encryption processes, using the SSL protocol for encryption and decryption.
-
-The presentation layer provides abstraction and assumes that the layers following it will take care of the data forwarded to them from this layer. It also plays a role in compression of the data. The compression can be lossy or lossless, depending on various factors beyond this article's scope.
-
-### Session layer
-
-The session layer helps in setting up and managing connections. The main work of this layer is to establish a session. For example, on an online shopping site, a session is created between your computer and the site's server.
-
-The session layer enables the sending and receiving of data, followed by the termination of connected sessions. Authentication is done before a session is established, followed by authorization. Like the previous layers, the session layer also assumes that, after its work is done, the data will be correctly handled by the subsequent layers.
-
-### Transport layer
-
-The transport layer manages data transportation and its own set of protocols for how data will be transferred. The data received here from the session layer is divided into smaller data units called segments. This process is known as segmentation. Every segment contains the source's and destination's port numbers and a sequence number. Port numbers identify the application on which the data needs to be sent. Note that the data is transferred in chunks. The sequence numbers are used to reassemble the segments in the correct order.
-
-The transport layer takes care of the flow control, or the amount of data transferred at a given time. It also accounts for error control, such as data loss, data corruption, and so on. It makes use of an error-detecting value known as a checksum. The transport layer adds a checksum to every data segment to check whether the sent data is received correctly. Data is then transferred to the network layer.
-
-### Network layer
-
-The network layer helps communicate with other networks. It works to transmit received data segments from one computer to another located in a different network. The router lives in the network layer.
-
-The function of the network layer is logical addressing (IP Addressing). It assigns the sender's and receiver's IP addresses to each data packet to ensure it is received at the correct destination. The network layer then routes the data packets. Load balancing also happens in the network layer to make sure that no overloading takes place. Next, the data is transported to the data link layer.
-
-### Data link layer
-
-The data link layer allows direct communication with other devices, such as computers and hosts.
-
-It receives data packets containing the IP addresses of the sender and receiver from the network layer and does the physical addressing, assigning the media access control (MAC) addresses of the sender and receiver to a data packet to form a frame.
-
-### Physical layer
-
-This layer consists of all the hardware and mechanical elements of a system, including the configuration of wires, pins, adapters, and so forth. The data received here by the preceding layers is in the form of 0s and 1s. The physical layer converts this data and transports it to local media via various means, including wires, electrical signals, light signals (as in optical fiber cables), and radio signals (as in WiFi).
-
-Note that the physical layer works at the receiver's end and transports the received signal to the data link as a frame (by converting it back to bits). The frame is moved to the higher layers, and ultimately the required data is received at the application layer, which is the software.
-
-### Conclusion
-
-The OSI model is helpful when you need to describe network architecture or troubleshoot network problems. I hope this article gave you a clearer understanding of the elements this model.

-How To Securely Transfer Files With SCP In Linux
-======
-
-File transfer over a network can be done in various ways and using different protocols. The most commonly used protocols for **copying files remotely** are **Rsync**, **SCP** and **SFTP**. In this guide, we will look at **what is SCP** and how to **securely transfer files between local and remote computers with SCP** in Linux and Unix-like operating systems.
-
-### What is SCP?
-
-SCP, stands for **Secure Copy**, is a command line program to copy files and directories between a local and a remote system or between two remote systems in a secure way in Linux and Unix-like operating systems.
-
-Using `scp` command, you can securely copy a file or a directory,
-
-- from your local system to a remote system,
-- from a remote system to your local system,
-- between remote systems from your local system.
-
-When transferring data with the scp command, the files and directories are both encrypted. So even if your network is compromised, the perpetrators can't get any meaningful data.
-
-SCP is a component of the openSSH program and it uses the SSH protocol to securely transfer files. OpenSSH comes pre-installed with almost all modern Linux and Unix distributions, so don't bother installing it.
-
-#### A word of caution:
-
-According to the **official announcement** from the openSSH developers,
-
-> The **scp protocol is outdated**, inflexible and not readily fixed. We recommend the use of more modern protocols like sftp and rsync for file transfer instead.
->
-> Link - [https://lists.mindrot.org/pipermail/openssh-unix-dev/2019-March/037672.html][1]
-
-However, the majority of the users still prefer SCP over other protocols. Because, SCP handles remote-to-remote file transfers more efficiently than its counterparts such as SFTP and Rsync.
-
-And also, SCP works exactly like `cp` command, while `rsync` changes its behavior based on whether the source directory has a **trailing slash** or not. Take a look at the following commands:
-
-- `rsync source destination/` - would copy the source into the destination folder.
-- `rsync source/ destination/` - would copy the contents of the source folder into the destination folder.
-
-So you must always double check if you've put the trailing slash in the path.
-
-I personally use **[Rsync][2]** for copying large size files between two hosts and SCP for copying single files over a network.
-
-### SCP Command Syntax
-
-The general syntax for SCP command is given below:
-
-```
-scp [-346ABCpqrTv] [-c cipher] [-F ssh_config] [-i identity_file] [-J destination] [-l limit] [-o ssh_option] [-P port] [-S program] source ... target
-```
-
-Depending upon the file transfer path, the syntax will differ. Here I have included some example syntax format.
-
-Copy a file from your local system to a remote system:
-
-```
-scp SourceFile User@RemoteHost:RemotePath
-```
-
-Similarly, to copy a directory from your local system to a remote system, use `-r` flag:
-
-```
-scp -r SourceDirectory User@RemoteHost:RemotePath
-```
-
-Copy multiple files to a remote system:
-
-```
-scp SourceFile1 SourceFile2 User@RemoteHost:RemotePath
-```
-
-Copy a file from remote system to your local system:
-
-```
-scp User@RemoteHost:RemoteFilePath DestinationFile
-```
-
-Copy a directory from remote system to local system:
-
-```
-scp -r User@RemoteHost:RemoteDirectoryPath DestinationDirectory
-```
-
-Copy a file from one remote system to another remote system from your local system:
-
-```
-scp User@RemoteHost1:RemoteFile1 User@RemoteHost2:RemotePath
-```
-
-Please note that when you copy files between two remote systems, the traffic will not pass through the local system. The operation takes place directly between two remote systems. You can, however, pass the traffic from the system on which you run scp command using `-3` option.
-
-Copy a directory from one remote system to another remote system from your local system:
-
-```
-scp -r User@RemoteHost1:RemoteDirectory User@RemoteHost2:DestinationPath
-```
-
-### SCP Command Options
-
-The most commonly used options of SCP command are:
-
-- **`-C`** : Enable compression. Here, C stands for Compression. When you use this option, the data transfer speed will be faster, because the data is compressed. SCP will automatically enable the compression at the source system and decompression at the destination system.
-- **`-c `** : c stands for cipher. By default, SCP uses **'AES-128'** encryption method for encrypting data. You can change the encryption method using `-c` option.
-- **`-i `** : i stands for Identity file or Private key. As you already know, there are password-based and key-based authentication used in SSH. If you want to use key-based authentication while transferring files, you can use the -i option to specify the Identity file or Private key.
-- **`-l limit`** : l stands for limit bandwidth. Using this option, you can set the maximum bandwidth used for transferring data. The limit should be specified in **`Kbit/s`**.
-- **`-F `** : Some times, you may need to use different networks to connect to your Linux systems. Or you may be behind a proxy server. In such situations, you can use different `ssh_config` file using `-F` option.
-- **`-P port`** - P stands for Port. Please note that it is uppercase P. By default, SSH uses port number 22. You might have changed the port number in the destination host for security reasons. In that case, you should explicitly mention the new port number using `-P` option.
-- **`-p`** : if you want to preserve modification times, access times, and modes from the original file, you need to use -p option while copying files. Please note that it is lowercase p.
-- **`-r`** : Recursively copy entire directories.
-- **`-B`** : B stands for batch mode. It is used for selecting batch mode while transferring files. It prevents asking for passwords or passphrases.
-- **`-S program`** : Name of the program to use for the encrypted connection.
-- **`-v`** : v stands for verbose. When using the `-v` option, the command will print the progress in your Terminal screen. So, you will see the what exactly is going on when the files are being transferred. It is useful in debugging connection, authentication, and configuration problems.
-
-SCP has so many options. You can check the man pages of SCP command to learn about other options. Let us see some **useful scp command examples**.
-
-### Important Notes to Remember before You Begin
-
-- The `scp` command relies on `ssh` for secure file transfer. So you must have either a **ssh key** or **password** to authenticate to the remote systems.
-- To be able to transfer files, you must have **read permission on the source files** and **write permission on the destination** location.
-- The `scp` command will not check the destination location before writing. Any files in the destination with the same name will be **overwritten without notification**.
-- To be able to distinguish between local and remote locations, use a **colon** (**`:`**).
-- When transferring large files, it is recommended to start the task inside a **[Screen][3]** or **[Tmux][4]** session.
-
-### Transfer Files With SCP in Linux
-
-As I already mentioned, we can use `scp` command to copy a file or a directory from a local system to a remote system and vice versa and copy files and folders between one remote computer to another remote computer.
-
-#### 1 Copy Files with SCP from Local System to Remote System
-
-To copy a file from a local system to a remote system using `scp` command, run:
-
-```
-$ scp File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-**Sample Output:**
-
-```
-ostechnix@192.168.1.40's password:
-File1.txt 100% 104 814.0KB/s 00:00
-```
-
-Let us break down the above command and see what each option does.
-
-- `**File1.txt**` - The source file to be copied to the destination.
-- `**ostechnix**` - The username of the remote system.
-- `**192.168.1.40**` - The IP address of the remote system.
-- `**/home/ostechnix/**` - The destination directory in the remote system. This is the absolute path where we want to transfer the source file i.e. `File.txt`.
-
-You can also copy the file and rename it as well. The following command transfers the **`File1.txt`** to the destination and saves the file with different name **`myfile.txt`**.
-
-```
-$ scp File1.txt ostechnix@192.168.1.40:/home/ostechnix/myfile.txt
-```
-

-
-#### 2. Copy Multiple Files with SCP from Local System to Remote System
-
-To transfer multiple files from a local system to a remote system with `scp` command, run:
-
-```
-$ scp File1.txt File2.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-**Sample Output:**
-
-```
-ostechnix@192.168.1.40's password:
-File1.txt 100% 104 689.4KB/s 00:00
-File2.txt 100% 496 6.3MB/s 00:00
-```
-
-![Copy Multiple Files from Local System to Remote System][6]
-
-Copy Multiple Files from Local System to Remote System
-
-Here,
-
-- `**File1.txt**` and **`File2.txt`** - The name of the sources that will be copied to the specified destination.
-- `**ostechnix@192.168.1.40**` - The username and IP address of the remote system.
-- `**/home/ostechnix**` - The destination path where we want to put the copied files.
-
-If the files have same extension, you can use the following alternative commands to achieve the same goal.
-
-```
-$ scp {File1,File2}.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-Or,
-
-```
-$ scp *.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-#### 3. Recursively Copy Directories with SCP from Local System to Remote System
-
-To recursively copy an entire directory including the sub-directories and its contents from your local system to a remote system, use **`-r`** flag like below.
-
-```
-$ scp -r Documents/ ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-![Copy a Directory from Local System to Remote System][7]
-
-Copy a Directory from Local System to Remote System
-
-The above command will copy the entire directory **'`Documents`'** including its contents to the destination system.
-
-Here,
-
-- **`-r`** : Copy files and directories recursively including the sub-directories and its contents.
-- **`Documents`** : The name of the source directory that we want to copy to the destination.
-- `**ostechnix@192.168.1.40**` : The username and IP address of the remote system.
-- `**/home/ostechnix**` : The destination path where we want to put the copied directory.
-
-#### 4. Transfer Files with SCP from Remote System to Local System
-
-Remember we copied `FIle1.txt` to the remote system from our local system. Let us copy it back to the local system.
-
-To copy a file from a remote system to your local system with `scp`, run:
-
-```
-$ scp ostechnix@192.168.1.40:/home/ostechnix/File1.txt Downloads/
-```
-
-Here,
-
-- `**ostechnix@192.168.1.40**` : The username and IP address of the remote system.
-- **`/home/ostechnix/File.txt`** : The absolute path of file that we want to copy to the local system.
-- **`Downloads`** - The location where to save the copied file.
-

-
-#### 5. Transfer Multiple Files using SCP from Remote System to Local System
-
-To copy multiple files from a remote system to your local system, mention the absolute path of the files that you want to copy **within the curly braces** as shown below.
-
-```
-$ scp ostechnix@192.168.1.40:/home/ostechnix/\{File1.txt,File2.txt\} Downloads/
-```
-
-![Transfer Multiple Files from Remote System to Local System][9]
-
-Transfer Multiple Files from Remote System to Local System
-
-The above command will copy the `File1.txt` and `File2.txt` from the `/home/ostechnix/` directory of the remote system to the `Downloads` directory of the local system.
-
-Please note that there is **no spaces after the commas within the curly braces**.
-
-#### 6. Recursively Copy Directories from Remote System to Local System
-
-To copy an entire directory including the sub-directories and its contents recursively from a remote computer to your local system using `scp`, use **`-r`** flag.
-
-```
-$ scp -r ostechnix@192.168.1.40:/home/ostechnix/Documents Downloads/
-```
-
-The above command will copy the entire **`Documents`** from the remote system to the **`Downloads`** directory in your local system.
-
-#### 7. Copy Files using SCP between Two Remote Computers
-
-To copy files directly from one remote system to another remote system with `scp`, run:
-
-```
-$ scp senthil@192.168.1.40:/home/senthil/File1.txt kumar@192.168.1.20:/home/kumar/
-```
-
-You will be asked to enter the password of the both remote systems.
-
-Here,
-
-- **`senthil@192.168.1.40`** - The username and IP address of the remote system from the file is currently located.
-- **`/home/senthil/File1.txt`** - The name the file1 that is being copied and its location.
-- `**kumar@192.168.1.20**` - The username and IP address of the remote system where we want to copy the file.
-- **`/home/kumar`** - The location where to save the copied file on the remote system.
-
-The above command will copy the `/home/senthil/File1.txt` from the remote host `192.168.1.40` to `/home/kumar/` directory on the remote host `192.168.1.20`.
-
-In this method, the data will be transferred directly from one remote system to another remote system. If you want to route the traffic through the machine on which the command is run, use `**-3**` flag like below.
-
-```
-$ scp -3 senthil@192.168.1.40:/home/senthil/File1.txt kumar@192.168.1.20:/home/kumar/
-```
-
-#### 8. Enable Compression while Copying Files with SCP
-
-So far we have transferred files without compressing them. Now we will enable compression while transferring files using **`-C`** flag.
-
-```
-$ scp -C File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-The `-C` flag will enable compression of data at the source and automatically decompress the data at destination side.
-
-By enabling compression, you can increase the file copy or transfer speed significantly.
-
-#### 9. Limit Bandwidth while Transferring Files using SCP
-
-We can limit the bandwidth while copying files with SCP using `-l` flag. Please note that the maximum bandwidth is specified in Kbits/s. 1 byte=8 bits. So if you want to limit bandwidth to 200 KB/s, the value for `-l` would be **1600** (200*8).
-
-```
-$ scp -l 1600 File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-This is useful when transferring large files to prevent SCP from throttling the bandwidth.
-
-#### 10. Use Different Port while Copying Files using SCP
-
-As a system admin, you might **[have changed the default port of your SSH protocol][10]** on the remote servers for security reasons. In such cases, you can specify the port number with `-P` flag when transferring files. Please note that this is **uppercase P**.
-
-```
-$ scp -P 2022 File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-#### 11. Use Different Cipher while Copying Files with SCP
-
-By default, SCP uses **'`AES-128`'** for encrypting files. If you want to use different cipher, use **`-c`** flag followed by the cipher name.
-
-For example, if you want to use **'`3des-cbc`'** cipher, the command would be like below:
-
-```
-$ scp -c 3des-cbc File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-To view the list of supported ciphers, run:
-
-```
-$ ssh -Q cipher localhost | paste -d, -s -
-```
-
-**Sample Output:**
-
-```
-3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,rijndael-cbc@lysator.liu.se,aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm@openssh.com,aes256-gcm@openssh.com,chacha20-poly1305@openssh.com
-```
-
-#### 12. Copying Files with SCP in Verbose Mode
-
-if you want to know what's going on behind the scenes while copying files with scp, you can use `**-v**` flag. When transferring files with SCP in Verbose mode, the step by step process of the SCP command execution will be displayed in the terminal. This comes in handy when troubleshooting times.
-
-```
-$ scp -v File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-You will see a whole lot of output when sending files in Verbose mode as shown in the following output.
-
-![Copying Files with SCP in Verbose Mode][11]
-
-Copying Files with SCP in Verbose Mode
-
-#### 13. Transferring Files with SCP in Quiet Mode
-
-We can transfer files in quiet mode with **`-q`** flag. When sharing files in quiet mode, it will not show the copy progress, warning or diagnostic message in the output.
-
-```
-$ scp -q File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-#### 14. Preserve File Attributes when Transferring Files with SCP
-
-To preserve file attributes such as file modification times, access times, and modes when copying files with SCP, use **`-p`** flag. Please note that this is **lowercase p**.
-
-```
-$ scp -p File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-#### 15. Use Identity File when Copying Files with SCP
-
-SSH supports both password-based and key-based authentication. Key-based authentication is most widely used authentication method in Linux environments.
-
-If you want to use key-based authentication while transferring files, use the **`-i`** option to specify the Identity file or Private key.
-
-```
-$ scp -i my_private_key.pem File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-#### 16. Use Different ssh_config File when Transferring Files with SCP
-
-There are situations where you need to use different networks to connect to your Linux systems. Or you may be behind a proxy server. In such situations, you can use different `ssh_config` file using `**-F**` option.
-
-```
-$ scp -F /home/ostechnix/my_ssh_config File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-
-#### 17. Copy files with SCP using IPv4 or IPv6
-
-We can force SCP to only use IPv4 or IPv6 addresses when copying files. This can be achieved by adding **`-4`** for IPv4 networks and **`-6`** for IPv6 networks.
-
-```
-$ scp -6 File1.txt ostechnix@192.168.1.40:/home/ostechnix/
-```
-

-7 Reasons Why Cinnamon is a Fantastic (Yet Underrated) Linux Desktop Environment
-======
-
-Linux Mint is one of my favorite distributions. The flagship (or default) Cinnamon desktop is why I like it so much.
-
-The user experience offered by Cinnamon desktop may not be mind-blowing or fancy. But, the desktop environment provides enough reasons for users to like it and easily work with it to get things done.
-
-At the end of the day, that’s what we want. A user interface that works as expected and does not get in the way.
-
-I think Cinnamon desktop does a few things right to give you an exciting experience. Let me mention some of those here.
-
-**If you did not know**, the Cinnamon desktop is a fork of the GNOME 3 created in **2011** by **Clement Lefebvre** (Linux Mint creator) with enhancements over the years.
-
-### 1. Familiar User Interface
-
-![linux mint 21 full][1]
-
-The primary objective of building Cinnamon was to keep the GNOME 2 desktop style alive.
-
-And that is why you get a familiar desktop layout compared to the most popular consumer desktop operating system, i.e., Windows.
-
-Of course, Windows 11 has evolved its usual layout with time. But, accessing a start menu, a taskbar, system icons in the tray, and a couple of window decorations make it easy to grasp.
-
-Whether you are a Windows user or a macOS user, the Cinnamon desktop layout should not feel challenging at all.
-
-![linux mint welcome][2]
-
-To help you further, the “**Welcome Screen**” in Linux Mint provides you with all the information quickly.
-
-### 2. Lightweight
-
-To get a comfortable experience with Cinnamon desktop (usually with Linux Mint), you have the following system requirements:
-
-- 4 GB RAM
-- 100 GB of disk space
-- 1024×768 resolution screen
-
-In the modern computing age, these specifications should suit almost everyone. So, you do not have to worry about needing an insane amount of memory or disk space to run a Linux distro powered by Cinnamon.
-
-Of course, you can try [installing Cinnamon desktop on Ubuntu][3].
-
-But, for this article, we consider Linux Mint as the ideal use case.
-
-### 3. Fast Performance Without Sacrificing User Experience
-
-When we think about a lightweight desktop environment—we usually imagine a bland user interface that focuses on performance.
-
-![linux mint perf][4]
-
-With Cinnamon desktop, that is not the case. It does include subtle animations and features icons/themes that make up for a modern look, if not the best.
-
-It looks pleasing to the eyes with a minimal approach.
-
-Typically, I am a sucker for pretty user interfaces, but I can still live with Linux Mint’s straightforward user experience running it on a dual-monitor setup (**1440p + 1080p**).
-
-It may not be the best dual-monitor experience with Linux Mint Cinnamon edition (no dock/panel on the second screen for me). So, there is little room for improvement.
-
-### 4. Default Customization Options
-
-You might already know that KDE is probably the king when it comes to giving the ability to customize out-of-the-box.
-
-We have super useful guides if you are curious about going that way:
-
-- [KDE Customization Guide][5]
-- [How to Properly Theme KDE Plasma [In-depth Guide]][6]
-- [Best Gorgeous KDE Plasma Themes][7]
-
-But, for many users, it is **overwhelming**.
-
-I think Linux Mint gives the right amount of extra controls/customizations, which you also learn on its **Welcome Screen**.
-
-![cinnamon theme customize][8]
-
-Some of the elements that you can easily customize include:
-
-- Desktop color (accent)
-- Light/Dark theme toggle
-- Panel layout
-- Icons, buttons, and mouse pointer.
-
-You can head to the system settings and navigate to “Themes” to find the essential tweaks.
-
-**Recommended Read:**[7 Ways to Customize Cinnamon Desktop on Linux][9]
-
-### 5. Official Add-ons to Spice Up Your Experience
-
-![cinnamon desklet][10]
-
-Linux Mint supports various add-ons to enhance your experience. These are all part of its [Cinnamon Spices][11] offering. They include:
-
-- Themes
-- Extensions
-- Applets
-- Desklets
-
-Applets and Desklets are tiny programs that you can add on top of the panel (near the system tray) and the desktop, respectively.
-
-![applet cinnamon][12]
-
-You can manage system default applets or download more from the official repositories:
-
-![applets cinnamon][13]
-
-Similarly, you can add a Desklet from the available defaults or get a new one from the repositories.
-
-![desklet cinnamon][14]
-
-Plenty of valuable utilities to monitor system resources, check the weather, and more.
-
-In addition, you get access to various themes built by the community that could easily give you a look you always wanted.
-
-![cinnamon theme][15]
-
-To complement all the above spices, you can use extensions to make the panel transparent, add a watermark to your desktop, enable windows tiling, and add some exciting window animations.
-
-![linux mint extensions][16]
-
-### 6. Compatible and Seamless User Experience
-
-Why do I highlight the user experience again?
-
-The best part about Cinnamon desktop is that it evolves in a way that respects and supports all functionalities.
-
-For instance, if you want to install an app you enjoyed using on KDE Plasma, it should work the same way here. There’s nothing special with Cinnamon desktop that would break the experience.
-
-![gnome accounts cinnamon][17]
-
-Similarly, the desktop adds features that try to co-exist with services from other desktop environments. For instance, calendar events support using GNOME Online Accounts.
-
-### 7. Panel Customization
-
-![linux mint panel][18]
-
-The dock, taskbar, or panel comprises an integral part of the user interface.
-
-Yes, other desktop environments allow you to customize the same to some extent. With Cinnamon, you get a good amount of control to tweak it.
-
-I think you get all the essential options a user would want.
-
-### Wrapping Up
-
-GNOME and KDE Plasma are popular desktop environments. However, Cinnamon is not far off on essential parts to provide an optimal user experience.

-Introducing Rust calls to C library functions
-======
-
-Why call C functions from Rust? The short answer is software libraries. A longer answer touches on where C stands among programming languages in general and towards Rust in particular. C, C++, and Rust are systems languages, which give programmers access to machine-level data types and operations. Among these three systems languages, C remains the dominant one. The kernels of modern operating systems are written mainly in C, with assembly language accounting for the rest. The standard system libraries for input and output, number crunching, cryptography, security, networking, internationalization, string processing, memory management, and more, are likewise written mostly in C. These libraries represent a vast infrastructure for applications written in any other language. Rust is well along the way to providing fine libraries of its own, but C libraries—around since the 1970s and still growing—are a resource not to be ignored. Finally, C is still the [lingua franca][1] among programming languages: most languages can talk to C and, through C, to any other language that does so.
-
-### Two proof-of-concept examples
-
-Rust has an FFI (Foreign Function Interface) that supports calls to C functions. An issue for any FFI is whether the calling language covers the data types in the called language. For example, `ctypes` is an FFI for calls from Python into C, but Python doesn't cover the unsigned integer types available in C. As a result, `ctypes` must resort to workarounds.
-
-By contrast, Rust covers all the primitive (that is, machine-level) types in C. For example, the Rust `i32` type matches the C `int` type. C specifies only that the `char` type must be one byte in size and other types, such as `int`, must be at least this size; but nowadays every reasonable C compiler supports a four-byte `int`, an eight-byte `double` (in Rust, the `f64` type), and so on.
-
-There is another challenge for an FFI directed at C: Can the FFI handle C's raw pointers, including pointers to arrays that count as strings in C? C does not have a string type, but rather implements strings as character arrays with a non-printing terminating character, the _null terminator_ of legend. By contrast, Rust has two string types: `String` and `&str` (string slice). The question, then, is whether the Rust FFI can transform a C string into a Rust one—and the answer is _yes_.
-
-Pointers to structures also are common in C. The reason is efficiency. By default, a C structure is passed _by_value (that is, by a byte-per-byte copy) when a structure is either an argument passed to a function or a value returned from one. C structures, like their Rust counterparts, can include arrays and nest other structures and so be arbitrarily large in size. Best practice in either language is to pass and return structures by reference, that is, by passing or returning the structure's address rather than a copy of the structure. Once again, the Rust FFI is up to the task of handling C pointers to structures, which are common in C libraries.
-
-The first code example focuses on calls to relatively simple C library functions such as `abs` (absolute value) and `sqrt` (square root). These functions take non-pointer scalar arguments and return a non-pointer scalar value. The second code example, which covers strings and pointers to structures, introduces the [bindgen][2] utility, which generates Rust code from C interface (header) files such as `math.h` and `time.h`. C header files specify the calling syntax for C functions and define structures used in such calls. The two code examples are [available on my homepage][3].
-
-### Calling relatively simple C functions
-
-The first code example has four Rust calls to C functions in the standard mathematics library: one call apiece to `abs` (absolute value) and `pow` (exponentiation), and two calls to `sqrt` (square root). The program can be built directly with the `rustc` compiler, or more conveniently with the `cargo build` command:
-
-```
-use std::os::raw::c_int; // 32 bits
-use std::os::raw::c_double; // 64 bits
-
-// Import three functions from the standard library libc.
-// Here are the Rust declarations for the C functions:
-extern "C" {
- fn abs(num: c_int) -> c_int;
- fn sqrt(num: c_double) -> c_double;
- fn pow(num: c_double, power: c_double) -> c_double;
-}
-
-fn main() {
- let x: i32 = -123;
- println!("\nAbsolute value of {x}: {}.", unsafe { abs(x) });
-
- let n: f64 = 9.0;
- let p: f64 = 3.0;
- println!("\n{n} raised to {p}: {}.", unsafe { pow(n, p) });
-
- let mut y: f64 = 64.0;
- println!("\nSquare root of {y}: {}.", unsafe { sqrt(y) });
-
- y = -3.14;
- println!("\nSquare root of {y}: {}.", unsafe { sqrt(y) }); //** NaN = NotaNumber
-}
-```
-
-The two `use` declarations at the top are for the Rust data types `c_int` and `c_double`, which match the C types `int` and `double`, respectively. The standard Rust module `std::os::raw` defines fourteen such types for C compatibility. The module `std::ffi` has the same fourteen type definitions together with support for strings.
-
-The `extern "C"` block above the `main` function then declares the three C library functions called in the `main` function below. Each call uses the standard C function's name, but each call must occur within an `unsafe` block. As every programmer new to Rust discovers, the Rust compiler enforces memory safety with a vengeance. Other languages (in particular, C and C++) do not make the same guarantees. The `unsafe` block thus says: Rust takes no responsibility for whatever unsafe operations may occur in the external call.
-
-The first program's output is:
-
-```
-Absolute value of -123: 123.
-9 raised to 3: 729
-Square root of 64: 8.
-Square root of -3.14: NaN.
-```
-
-In the last output line, the `NaN` stands for Not a Number: the C `sqrt` library function expects a non-negative value as its argument, which means that the argument -3.14 generates `NaN` as the returned value.
-
-### Calling C functions involving pointers
-
-C library functions in security, networking, string processing, memory management, and other areas regularly use pointers for efficiency. For example, the library function `asctime` (time as an ASCII string) expects a pointer to a structure as its single argument. A Rust call to a C function such as `asctime` is thus trickier than a call to `sqrt`, which involves neither pointers nor structures.
-
-The C structure for the `asctime` function call is of type `struct tm`. A pointer to such a structure also is passed to library function `mktime` (make a time value). The structure breaks a time into units such as the year, the month, the hour, and so forth. The structure's fields are of type `time_t`, an alias for for either `int` (32 bits) or `long` (64 bits). The two library functions combine these broken-apart time pieces into a single value: `asctime` returns a string representation of the time, whereas `mktime` returns a `time_t` value that represents the number of elapsed seconds since the _epoch_, which is a time relative to which a system's clock and timestamp are determined. Typical epoch settings are January 1 00:00:00 (zero hours, minutes, and seconds) of either 1900 or 1970.
-
-The C program below calls `asctime` and `mktime`, and uses another library function `strftime` to convert the `mktime` returned value into a formatted string. This program acts as a warm-up for the Rust version:
-
-```
-#include
-#include
-
-int main () {
- struct tm sometime; /* time broken out in detail */
- char buffer[80];
- int utc;
-
- sometime.tm_sec = 1;
- sometime.tm_min = 1;
- sometime.tm_hour = 1;
- sometime.tm_mday = 1;
- sometime.tm_mon = 1;
- sometime.tm_year = 1;
- sometime.tm_hour = 1;
- sometime.tm_wday = 1;
- sometime.tm_yday = 1;
-
- printf("Date and time: %s\n", asctime(&sometime));
-
- utc = mktime(&sometime);
- if( utc < 0 ) {
- fprintf(stderr, "Error: unable to make time using mktime\n");
- } else {
- printf("The integer value returned: %d\n", utc);
- strftime(buffer, sizeof(buffer), "%c", &sometime);
- printf("A more readable version: %s\n", buffer);
- }
-
- return 0;
-}
-```
-
-The program outputs:
-
-```
-Date and time: Fri Feb 1 01:01:01 1901
-The integer value returned: 2120218157
-A more readable version: Fri Feb 1 01:01:01 1901
-```
-
-In summary, the Rust calls to library functions `asctime` and `mktime` must deal with two issues:
-
-- Passing a raw pointer as the single argument to each library function.
-- Converting the C string returned from `asctime` into a Rust string.
-
-### Rust calls to `asctime` and `mktime`
-
-The `bindgen` utility generates Rust support code from C header files such as `math.h` and `time.h`. In this example, a simplified version of `time.h` will do but with two changes from the original:
-
-- The built-in type `int` is used instead of the alias type `time_t`. The bindgen utility can handle the `time_t` type but generates some distracting warnings along the way because `time_t` does not follow Rust naming conventions: in `time_t` an underscore separates the `t` at the end from the `time` that comes first; Rust would prefer a CamelCase name such as `TimeT`.
-- The type `struct tm` type is given `StructTM` as an alias for the same reason.
-
-Here is the simplified header file with declarations for `mktime` and `asctime` at the bottom:
-
-```
-typedef struct tm {
- int tm_sec; /* seconds */
- int tm_min; /* minutes */
- int tm_hour; /* hours */
- int tm_mday; /* day of the month */
- int tm_mon; /* month */
- int tm_year; /* year */
- int tm_wday; /* day of the week */
- int tm_yday; /* day in the year */
- int tm_isdst; /* daylight saving time */
-} StructTM;
-
-extern int mktime(StructTM*);
-extern char* asctime(StructTM*);
-```
-
-With `bindgen` installed, `%` as the command-line prompt, and `mytime.h` as the header file above, the following command generates the required Rust code and saves it in the file `mytime.rs`:
-
-```
-% bindgen mytime.h > mytime.rs
-```
-
-Here is the relevant part of `mytime.rs`:
-
-```
-/* automatically generated by rust-bindgen 0.61.0 */
-
-#[repr(C)]
-#[derive(Debug, Copy, Clone)]
-pub struct tm {
- pub tm_sec: ::std::os::raw::c_int,
- pub tm_min: ::std::os::raw::c_int,
- pub tm_hour: ::std::os::raw::c_int,
- pub tm_mday: ::std::os::raw::c_int,
- pub tm_mon: ::std::os::raw::c_int,
- pub tm_year: ::std::os::raw::c_int,
- pub tm_wday: ::std::os::raw::c_int,
- pub tm_yday: ::std::os::raw::c_int,
- pub tm_isdst: ::std::os::raw::c_int,
-}
-
-pub type StructTM = tm;
-
-extern "C" {
- pub fn mktime(arg1: *mut StructTM) -> ::std::os::raw::c_int;
-}
-
-extern "C" {
- pub fn asctime(arg1: *mut StructTM) -> *mut ::std::os::raw::c_char;
-}
-
-#[test]
-fn bindgen_test_layout_tm() {
- const UNINIT: ::std::mem::MaybeUninit = ::std::mem::MaybeUninit::uninit();
- let ptr = UNINIT.as_ptr();
- assert_eq!(
- ::std::mem::size_of::(),
- 36usize,
- concat!("Size of: ", stringify!(tm))
- );
- ...
-```
-
-The Rust structure `struct tm`, like the C original, contains nine 4-byte integer fields. The field names are the same in C and Rust. The `extern "C"` blocks declare the library functions `asctime` and `mktime` as taking one argument apiece, a raw pointer to a mutable `StructTM` instance. (The library functions may mutate the structure via the pointer passed as an argument.)
-
-The remaining code, under the `#[test]` attribute, tests the layout of the Rust version of the time structure. The test can be run with the `cargo test` command. At issue is that C does not specify how the compiler must lay out the fields of a structure. For example, the C `struct tm` starts out with the field `tm_sec` for the second; but C does not require that the compiled version has this field as the first. In any case, the Rust tests should succeed and the Rust calls to the library functions should work as expected.
-
-### Getting the second example up and running
-
-The code generated from `bindgen` does not include a `main` function and, therefore, is a natural module. Below is the `main` function with the `StructTM` initialization and the calls to `asctime` and `mktime`:
-
-```
-mod mytime;
-use mytime::*;
-use std::ffi::CStr;
-
-fn main() {
- let mut sometime = StructTM {
- tm_year: 1,
- tm_mon: 1,
- tm_mday: 1,
- tm_hour: 1,
- tm_min: 1,
- tm_sec: 1,
- tm_isdst: -1,
- tm_wday: 1,
- tm_yday: 1
- };
-
- unsafe {
- let c_ptr = &mut sometime; // raw pointer
-
- // make the call, convert and then own
- // the returned C string
- let char_ptr = asctime(c_ptr);
- let c_str = CStr::from_ptr(char_ptr);
- println!("{:#?}", c_str.to_str());
-
- let utc = mktime(c_ptr);
- println!("{}", utc);
- }
-}
-```
-
-The Rust code can be compiled (using either `rustc` directly or `cargo`) and then run. The output is:
-
-```
-Ok(
- "Mon Feb 1 01:01:01 1901\n",
-)
-2120218157
-```
-
-The calls to the C functions `asctime` and `mktime` again must occur inside an `unsafe` block, as the Rust compiler cannot be held responsible for any memory-safety mischief in these external functions. For the record, `asctime` and `mktime` are well behaved. In the calls to both functions, the argument is the raw pointer `ptr`, which holds the (stack) address of the `sometime` structure.
-
-The call to `asctime` is the trickier of the two calls because this function returns a pointer to a C `char`, the character `M` in `Mon` of the text output. Yet the Rust compiler does not know where the C string (the null-terminated array of `char`) is stored. In the static area of memory? On the heap? The array used by the `asctime` function to store the text representation of the time is, in fact, in the static area of memory. In any case, the C-to-Rust string conversion is done in two steps to avoid compile-time errors:
-
-- The call `Cstr::from_ptr(char_ptr)` converts the C string to a Rust string and returns a reference stored in the `c_str` variable.
-- The call to `c_str.to_str()` ensures that `c_str` is the owner.
-
-The Rust code does not generate a human-readable version of the integer value returned from `mktime`, which is left as an exercise for the interested. The Rust module `chrono::format` includes a `strftime` function, which can be used like the C function of the same name to get a text representation of the time.
-
-### Calling C with FFI and bindgen
-
-The Rust FFI and the `bindgen` utility are well designed for making Rust calls out to C libraries, whether standard or third-party. Rust talks readily to C and thereby to any other language that talks to C. For calling relatively simple library functions such as `sqrt`, the Rust FFI is straightforward because Rust's primitive data types cover their C counterparts.
-
-For more complicated interchanges—in particular, Rust calls to C library functions such as `asctime` and `mktime` that involve structures and pointers—the `bindgen` utility is the way to go. This utility generates the support code together with appropriate tests. Of course, the Rust compiler cannot assume that C code measures up to Rust standards when it comes to memory safety; hence, calls from Rust to C must occur in `unsafe` blocks.

-Write a C++ extension module for Python
-======
-
-In a previous article, I gave an overview of [six Python interpreters][1]. On most systems, the CPython interpreter is the default, and also the poll in my last article showed that CPython is the most popular one. Specific to CPython is the ability to write Python modules in C using CPythons extensions API. Writing Python modules in C allows you to move computation-intensive code to C while preserving the ease of access of Python.
-
-In this article, I’ll show you how to write an extension module. Instead of plain C, I use C++ because most compilers usually understand both. I have to mention one major drawback in advance: Python modules built this way are not portable to other interpreters. They only work in conjunction with the CPython interpreter. So if you are looking for a more portable way of interacting with C libraries, consider using the [ctypes][2] module.
-
-### Source code
-
-As usual, you can find the related source code on [GitHub][3]. The C++ files in the repository have the following purpose:
-
-- `my_py_module.cpp`: Definition of the Python module _MyModule_
-- `my_cpp_class.h`: A header-only C++ class which gets exposed to Python
-- `my_class_py_type.h/cpp`: Python representation of our C++ class
-- `pydbg.cpp`: Separate application for debugging purpose
-
-The Python module you build in this article won’t have any meaningful use, but is a good example.
-
-### Build the module
-
-Before looking into the source code, you can check whether the module compiles on your system. [I use CMake][4] for creating the build configuration, so CMake must be installed on your system. In order to configure and build the module, you can either let Python run the process:
-
-```
-$ python3 setup.py build
-```
-
-Or run the process manually:
-
-```
-$ cmake -B build
-$ cmake --build build
-```
-
-After that, you have a file called `MyModule.so` in the `/build` subdirectory.
-
-### Defining an extension module
-
-First, take a look on `my_py_module.cpp`, in particular, the function `PyInit_MyModule`:
-
-```
-PyMODINIT_FUNC
-PyInit_MyModule(void) {
- PyObject* module = PyModule_Create(&my_module);
-
- PyObject *myclass = PyType_FromSpec(&spec_myclass);
- if (myclass == NULL){
- return NULL;
- }
- Py_INCREF(myclass);
-
- if(PyModule_AddObject(module, "MyClass", myclass) < 0){
- Py_DECREF(myclass);
- Py_DECREF(module);
- return NULL;
- }
- return module;
-}
-```
-
-This is the most important code in this example because it acts as the entry point for CPython. In general, when a Python C extension is compiled and made available as a shared object binary, CPython searches for the function `PyInit_` in the eponymous binary (`.so`) and executes it when attempting to import it.
-
-All Python types, whether declarations or instances, are exposed as pointers to [PyObject][5]. In the first part of this function, the root definition of the module is created by running `PyModule_Create(...)`. As you can see in the module specification (`my_module`, same file), it doesn’t have any special functionality.
-
-Afterward, [PyType_FromSpec][6] is called to create a Python [heap type][7] definition for the custom type MyClass. A heap type corresponds to a Python class. The type definition is then assigned to the module MyModule.
-
-_Note that if one of the functions fails, the reference count of previously created PyObjects must be decremented so that they get deleted by the interpreter._
-
-### Specifying a Python type
-
-The specification for the type MyClass is found inside [my_class_py_type.h][8] as an instance of [PyType_Spec][9]:
-
-```
-static PyType_Spec spec_myclass = {
- "MyClass", // name
- sizeof(MyClassObject) + sizeof(MyClass), // basicsize
- 0, // itemsize
- Py_TPFLAGS_DEFAULT | Py_TPFLAGS_BASETYPE, // flags
- MyClass_slots // slots
-};
-```
-
-This structure defines some basic type information for the class. The value passed for the size consists of the size of the Python representation (`MyClassObject`) and the size of the plain C++ class (`MyClass`). The `MyClassObject` is defined as follows:
-
-```
-typedef struct {
- PyObject_HEAD
- int m_value;
- MyClass* m_myclass;
-} MyClassObject;
-```
-
-The Python representation is basically of type [PyObject][5], defined by the macro `PyObject_HEAD`, and some additional members. The member `m_value` is exposed as ordinary class member while the member `m_myclass` is only accessible from inside C++ code.
-
-The [PyType_Slot][10] defines some additional functionality:
-
-```
-static PyType_Slot MyClass_slots[] = {
- {Py_tp_new, (void*)MyClass_new},
- {Py_tp_init, (void*)MyClass_init},
- {Py_tp_dealloc, (void*)MyClass_Dealloc},
- {Py_tp_members, MyClass_members},
- {Py_tp_methods, MyClass_methods},
- {0, 0} /* Sentinel */
-};
-```
-
-Here, the jump addressed for some initialization and de-initialization functions are set as well as ordinary class methods and members. Additional functionality, like assigning an initial attribute dictionary, could also be set, but this is optional. Those definitions usually end with a sentinel, consisting of `NULL` values.
-
-To complete the type specification, here is the method and member table:
-
-```
-static PyMethodDef MyClass_methods[] = {
- {"addOne", (PyCFunction)MyClass_addOne, METH_NOARGS, PyDoc_STR("Return an incrmented integer")},
- {NULL, NULL} /* Sentinel */
-};
-
-static struct PyMemberDef MyClass_members[] = {
- {"value", T_INT, offsetof(MyClassObject, m_value)},
- {NULL} /* Sentinel */
-};
-```
-
-In the method table, the Python method `addOne` is defined, and it points to the related function `MyClass_addOne`. This function acts as a wrapper. It invokes the `addOne()` method in the C++ class.
-
-In the member table, there is just one member defined for demonstration purposes. Unfortunately, the use of [offsetof][11] in [PyMemberDef][12] doesn’t allow C++ specific types to be added to `MyClassObject`. If you try to place some C++ type container (such as [std::optional][13]), the compiler complains about it in the form of warnings related to memory layout.
-
-### Initialization and de-initialization
-
-The method `MyClass_new` acts only to provide initial values for `MyClassObject` and allocates memory for the base type:
-
-```
-PyObject *MyClass_new(PyTypeObject *type, PyObject *args, PyObject *kwds){
- std::cout << "MtClass_new() called!" << std::endl;
-
- MyClassObject *self;
- self = (MyClassObject*) type->tp_alloc(type, 0);
- if(self != NULL){ // -> allocation successfull
- // assign initial values
- self->m_value = 0;
- self->m_myclass = NULL;
- }
- return (PyObject*) self;
-}
-```
-
-Actual initialization takes place in `MyClass_init`, which corresponds to the [__init__()][14] method in Python:
-
-```
-int MyClass_init(PyObject *self, PyObject *args, PyObject *kwds){
-
- ((MyClassObject *)self)->m_value = 123;
-
- MyClassObject* m = (MyClassObject*)self;
- m->m_myclass = (MyClass*)PyObject_Malloc(sizeof(MyClass));
-
- if(!m->m_myclass){
- PyErr_SetString(PyExc_RuntimeError, "Memory allocation failed");
- return -1;
- }
-
- try {
- new (m->m_myclass) MyClass();
- } catch (const std::exception& ex) {
- PyObject_Free(m->m_myclass);
- m->m_myclass = NULL;
- m->m_value = 0;
- PyErr_SetString(PyExc_RuntimeError, ex.what());
- return -1;
- } catch(...) {
- PyObject_Free(m->m_myclass);
- m->m_myclass = NULL;
- m->m_value = 0;
- PyErr_SetString(PyExc_RuntimeError, "Initialization failed");
- return -1;
- }
-
- return 0;
-}
-```
-
-If you want to have arguments passed during initialization, you must call [PyArg_ParseTuple][15] at this point. For the sake of simplicity, all arguments passed during initialization are ignored in this example. In the first part of the function, the `PyObject` pointer (`self`) is reinterpreted to a pointer to `MyClassObject` in order to get access to our additional members. Additionally, the memory for the C++ class is allocated and its constructor is executed.
-
-Note that exception handling and memory allocation (and de-allocation) must be carefully done in order to prevent memory leaks. When the reference count drops to zero, the `MyClass_dealloc` function takes care of freeing all related heap memory. There’s a [dedicated chapter][16] in the documentation about memory management for C and C++ extensions.
-
-### Method wrapper
-
-Calling a related C++ class method from the Python class is easy:
-
-```
-PyObject* MyClass_addOne(PyObject *self, PyObject *args){
- assert(self);
-
- MyClassObject* _self = reinterpret_cast(self);
- unsigned long val = _self->m_myclass->addOne();
- return PyLong_FromUnsignedLong(val);
-}
-```
-
-Again, the `PyObject*` argument (`self`) is casted to `MyClassObject*` in order to get access to `m_myclass`, a pointer to the C++ class instance. With this information, the classes method `addOne()` is called and the result is returned in form of a [Python integer object][17].
-
-### 3 ways to debug
-
-For debugging purposes, it can be valuable to compile the CPython interpreter in debugging configuration. A detailed description can be found in the [official documentation][18]. It’s possible to follow the next steps, as long as additional debug symbols for the pre-installed interpreter are downloaded.
-
-#### GNU Debugger
-
-Good old [GNU Debugger (GDB)][19] is, of course, also useful here. I include a [gdbinit][20] file, defining some options and breakpoints. There’s also the [gdb.sh][21] script, which creates a debug build and initiates a GDB session:
-
-![Gnu Debugger (GDB) is useful for your Python C and C++ extensions.][22]
-
-GDB invokes the CPython interpreter with the script file [main.py][23]. The script file allows you to easily define all the actions you want to perform with the Python extension module.
-
-#### C++ application
-
-Another approach is to embed the CPython interpreter in a separate C++ application. In the repository, this can be found in the file [pydbg.cpp][24]:
-
-```
-int main(int argc, char *argv[], char *envp[])
-{
- Py_SetProgramName(L"DbgPythonCppExtension");
- Py_Initialize();
-
- PyObject *pmodule = PyImport_ImportModule("MyModule");
- if (!pmodule) {
- PyErr_Print();
- std::cerr << "Failed to import module MyModule" << std::endl;
- return -1;
- }
-
- PyObject *myClassType = PyObject_GetAttrString(pmodule, "MyClass");
- if (!myClassType) {
- std::cerr << "Unable to get type MyClass from MyModule" << std::endl;
- return -1;
- }
-
- PyObject *myClassInstance = PyObject_CallObject(myClassType, NULL);
-
- if (!myClassInstance) {
- std::cerr << "Instantioation of MyClass failed" << std::endl;
- return -1;
- }
-
- Py_DecRef(myClassInstance); // invoke deallocation
- return 0;
-}
-```
-
-Using the [high level interface][25], it’s possible to include the extension module and perform actions on it. This allows you to debug in the native IDE environment. It also gives you finer control of the variables passed from and to the extension module.
-
-The drawback is the high expense of creating an extra application.
-
-#### VSCode and VSCodium LLDB extension
-
-Using a debugger extension like [CodeLLDB][26] is probably the most convenient debugging option. The repository includes the VSCode or VSCodium configuration files for building the extension ([task.json][27], [CMake Tools][28]) and invoking the debugger ([launch.json][29]). This approach combines the advantages of the previous ones: Debugging in an graphical IDE, defining actions in a Python script file or even dynamically in the interpreter prompt.
-
-![VSCodium features an integrated debugger.][30]
-
-### Extend C++ with Python
-
-All functionality available from Python code is also available from within a C or C++ extension. While coding in Python is often considered as an easy win, extending Python in C or C++ can also be a pain. On the other hand, while native Python code is slower than C++, a C or C++ extension makes it possible to elevate a computation-intensive task to the speed of native machine code.
-
-You must also consider the usage of an ABI. The stable ABI provides a way to maintain backwards compatibility to older versions of CPython as described in [the documentation][31].
-
-In the end, you must weigh the advantages and disadvantages yourself. Should you decide to use C extensions to make certain functionality available to you in Python, you’ve seen how it can be done.

-How I Fixed Buzzing Noise Coming from Speakers in Linux
-======
-
-I used a laptop for a long time but only recently switched to a desktop setup for my remote work at It’s FOSS.
-
-I noticed a constant buzzing sound coming from the speakers. It was annoying and gave me headaches. I started out to fix the issue. It was quite interesting to know the root cause of the issue.
-
-I will share my experience of fixing the buzzing noise from speakers in Linux. I found it working with Ubuntu, Debian and Pop OS on the same hardware.
-
-One thing to consider is that you may have a serious hardware issue if this guide does not work for you. For most users, the given solution should get the job done.
-
-**Before you try the fix …**
-
-I have tried to make things easy to follow safely. You try the temporary fix and if it works, you make the changes permanent. However, it would be a good idea to make system snapshots with Timeshift. If you are easily panicked when things do not work, you can restore the system to the earlier state.
-
-Also, check your sound card. In my case, it was snd_hda_intel. For USB card, it could be snd_usb_audio. You have to change the commands according to your sound card.
-
-```
-cat /proc/asound/modules
-```
-
-### The reason behind the buzzing noise from speakers in Linux
-
-After combing through numerous forum posts and websites, I learned the root cause of the issue. It is because of capacitor discharge in the speakers. And it can be solved by turning off the power-saving setting of a sound card.
-
-By turning off power saving, you are allowing the system to charge those capacitors when they get discharged. It is similar to using a phone while charging constantly.
-
-And you can check whether the power-saving setting for the sound card is enabled on your system by using the given command:
-
-```
-cat /sys/module/snd_hda_intel/parameters/power_save
-```
-
-![power saving setting in sound card making buzzing sound in linux][1]
-
-And if you get 1 in output like mine, the power saving is turned on. So let’s have a look at the solution.
-
-Don’t worry. This will not affect your battery percentage drastically, as the shown method is only applied to the sound card.
-
-### Try fixing the buzzing noise issue (temporary)
-
-The reason why I included the temporary way is to identify whether the humming sound is being caused due to capacitor discharge or if there is any serious hardware problem going on.
-
-If this temporary solution works, you can go ahead with the permanent solution.
-
-The first step is to switch to the root user:
-
-```
-sudo su
-```
-
-And then, execute the given command, and it should stop the buzzing sound until the next boot:
-
-```
-echo 0 > /sys/module/snd_hda_intel/parameters/power_save
-```
-
-If you are using **a USB sound card**, you have to interchange `snd_hda_intel` with `snd_usb_audio` as given:
-
-```
-echo 0 > /sys/module/snd_usb_audio/parameters/power_save
-```
-
-If the above trick fixed the issue, you have to make things permanent. Otherwise, the changes will be lost when you next reboot your system.
-
-### Fixing the buzzing noise issue (permanently)
-
-Here, I’m going to make changes in kernel parameters.
-
-Change your working directory to /etc/modprobe.d:
-
-```
-cd /etc/modprobe.d
-```
-
-And now, create a new file named `audio_disable_powersave.conf` and open with the nano text editor using the given command:
-
-```
-sudo nano audio_disable_powersave.conf
-```
-
-And put the following lines in that file to turn off the power-saving setting in the sound card permanently:
-
-```
-options snd_hda_intel power_save=0
-```
-
-![fix buzzing sound in linux][2]
-
-For **a USB sound card**, you can use `snd_usb_audio`:
-
-```
-options snd_usb_audio power_save=0
-```
-
-Now, [save changes and exit the Nano text editor][3] by pressing Ctrl+X keys. Reboot your system, and you can enjoy a noise-free workspace.
-
-### Wrapping Up
-
-This guide explains the cause of the buzzing noise and how you can straightforwardly solve that issue.
-
-Again, you may have some other issue rather than discharging capacitors, so you should always try the temporary method.
-
-Let me know if you were able to fix the buzzing noise from speakers in Linux this way or not.

-Create a holiday light display with your Raspberry Pi and ping pong balls
-======
-
-I love Christmas decorations and lights, and I'd been wanting to do an programmable LED project for a long time. Recently, I built a light array made of LED lights, ping pong balls, and a Raspberry Pi Zero. I thought it was worth sharing, because it ended up being relatively easy but also educational.
-
-It's mostly my own design, with some inspiration from YouTube videos. You can find the source code and build instructions in my [Git repository][1].
-
-### Shopping list
-
-- [Raspberry Pi Zero][2]
-- [Pibow Case][3]
-- 5v 2A USB power supply
-- Poster frame
-- 255 ping pong balls
-- Hot glue gun and LOTS of hot glue sticks
-- Soldering iron
-- Solder
-- 22 AWG 0.35mm solid core wiring
-- 10 meters of WS2812(B) LED strip lights (30 pixels per meter)
-- Multimeter
-- Wire cutters
-- Wire strippers
-
-### Design the Raspberry Pi light display
-
-My design was driven by the size of the poster frame I happened to have available. I got 30 pixel per meter tape from Ali Express, which cut nicely into 0.5m sections, so that gave me 15 LEDs across. Ping pong balls are 40mm, so I measured and placed the lines 40mm apart, with the LED Strip in the middle of each 40mm section. This gave me 17 lines down in total. My array was therefore 15×17. If you try this yourself, yours can be a different size.
-
-To get power to the array and the Raspberry Pi, I placed the open connections for both data and power at the bottom of the board. I didn't have that many LEDs needing power, so I was able to use the 5v out GPIO from the Raspberry Pi Zero to power them. I run them at 50% brightness, which is easily bright enough to see in the day and at night through my window.
-
-### Wiring
-
-In my design, I started at the bottom of the board and wired up in an S-curve. This made soldering easier because loops at the end of each row didn't have to return all the way back to the start of each line. The WS2812 data lines do require you to wire the data the correct way: power can be fed from either side of the strip, but data must be fed from the side with the arrows pointing away.
-
-My wiring looks like this (this is abbreviated for clarity, in real life it's 17 lines deep):
-
-```
-<---------------\
- |
-/---------------/
-|
-\---------------< # Pi connected here
-```
-
-### Build the display with your Raspberry Pi
-
-Once the design and wiring plan was sorted, it was time to get started on the build.
-
-I measured and drew my lines in pencil on the poster backboard. The WS2812 strips I got came with sticky tape on the back, so I just removed the backing and attached that directly to the backboard. I was sure to position each strip so that the data arrows went one way, then back the other, to ensure that the lights could be daisy-chained correctly for the Pi's instructions.
-
-Once all light strips were attached, I cut three similar lengths of wire and connected the 5v, data, and ground lines from the end of each light section to the one above it.
-
-![Connect each light strip at the end of each line.][4]
-
-After completing each row, I checked continuity between the 5v and ground lines between each strip to ensure my joins were correct. I also checked that I had not accidentally bridged any connections, so I verified that there was no continuity between the 5v and ground lines (in other words, a 5v wire on one line didn't bridge to the ground on the next line.) I also ran some tests to ensure everything was lighting up correctly (see [the code][5] section for my strand tests.)
-
-Once this was complete, I started to cut holes in the ping pong balls by stabbing scissors into the bottom of them, and cutting a small hole for the LED to shine into. There was no exact science to this, and each one was different, but the effect really worked. I was working with 30 pixels per meter, so my lighting had about 30mm between each LED. A ping pong ball is 40mm across, but I wasn't about to start soldering each LED individually! First of all, I'm not that good at soldering (as my photos show), and anyway, I thought "Well, they're ping pong balls. I can just squash them together!"
-
-And that's what I did.
-
-I placed a hot glue blob around each LED and then placed a ping pong ball onto the LED, held it for about five seconds, and moved on to the next one. I held onto the previous ping pong ball as I slid the next one in, pushing it against the first before "folding" it into its neighbor. The effect worked really well. I was happy with what it was looking like straight away. It also had the nice bonus of hiding my bad soldering job ;)
-
-![It's a tight fit, but the 40mm ping pong balls fit in a 30mm space just fine.][6]
-
-I continued doing this for 255 LEDs and ping pong balls. There were a few crushed ping pong balls in the process, but in the end, I got there.
-
-![255 LEDs and 255 ping pong balls in an array.][7]
-
-### Test the code
-
-For the test code to ensure that everything was working, I used this [Adafruit guide][8] which lights each LED in red, green, and blue, and then does a rainbow cycle. I used this when I was building to ensure my connections were correct and that everything was soldered correctly.
-
-After that, I designed a grid in a spreadsheet to map each pixel to a grid position. This helped to make building the images easier. Since my pixel numbers run in a zig-zag pattern, it would have been hard to keep track of each LED (e.g. LED A1 was 256 and B1 was 226).
-
-Once this was all set, it was time to design some images on paper and in the spreadsheet. Then it was time to code! It got a bit addictive and I started adding some animation (using loops and turning pixels onto one color and then another color).
-
-The end result was everything I'd hoped it would be.
-
-![A Christmas gift in LED.][9]
-
-![Reindeer painted with light.][10]
-
-![An LED snowflake.][11]
-
-### A Raspberry Pi light display all year
-
-I am not sure this will ever be truly finished. Nearly every night since it's been up in the window, I've added some new images and animations. I'm already thinking about what to do for New Year's Eve. I also won't be putting this back in storage with my Christmas decorations in January. I just need to think of other things to draw on it to make it a year-round project! A friend of mine suggested a pixel Mario and I love that idea!
-
-My code also needs a little work. For example, I do some scrolling text, but I redraw the whole board for each position of the text, so it took quite a bit of time to do. I think I can do something with loops, or perhaps the image library can help scroll the letters easier, and make it easier to add text rather than turning each pixel on and off at every step.
-
-I've got a photo record of my progress from start to finish: [LED Ping Pong Wall][12].
-
-You can also see a video of it in action here: [XMas light display][13].
-
-I'm really pleased with how this turned out, and I think it looks amazing. I'm very excited to try some other LED projects in the future. I encourage you to try a light array of your own even as your first project. It's easier than it looks!

-lnav: Advanced Log File Viewer for Linux Desktops and Servers
-======
-
-**If you want to debug or troubleshoot any issues, you need an advanced log file viewer like lnav – which works wonders in the terminal for any Linux system.**
-
-### lnav: Log file viewer
-
-lnav can unzip all the compressed log files on the fly and merge them together for a nice display. The display is parsed and formatted based on the types of errors/warnings – this helps to quickly glance through the thousands of logs, especially in servers.
-
-While analysing the logs, timestamps are very important. So lnav merges multiple logs based on timestamps, which is very helpful for tracking down system issues.
-
-Most of the important log file format detection is built-in; see below:
-
-- Common Web Access Log format
-- CUPS page_log
-- Syslog
-- Glog
-- VMware ESXi/vCenter Logs
-- dpkg.log
-- uwsgi
-- “Generic” – Any message that starts with a timestamp
-- Strace
-- sudo
-- GZIP, BZIP
-
-That is not all; lnav is also capable of the below features, making it an important app for Linux systems.
-
-- Filter messages based on regular expression
-- A timeline view of errors
-- Pretty-Print view- helps to reformat
-- Query Log using SQL
-- A log is updated in real-time while being searched.
-- Syntax highlight via regular expression (say you want to find out an IP address in the entire log)
-- Tab completion of any word from the log which is displayed !!
-
-![lnav-running-in-ubutu][1]
-
-To view the screenshots of the above features and learn more, visit [this page.][2]
-
-### How to Install
-
-This program is available in official Ubuntu, Debian repo. Install it using the following command.
-
-```
-sudo apt install lnav
-```
-
-And for Fedora, RHEL users, use the below command:
-
-```
-sudo dnf install lnav
-```
-
-Also the developers provides an offline standalone executable which you don’t need to install. You can download the zip from the [GitHub release page][3] and execute as:
-
-```
-./lnav
-```
-
-**Note**: It’s also available for macOS which you can find in the above GitHub page.
-
-### lnav: How to use (Basics)
-
-The simple command syntax is:
-
-```
-lnav [options] [logfile1 logfile2 …]
-```
-
-If you run just lnav from the command, it shows all the logs from your system (/var/log/messages and /var/log/syslog)
-
-```
-lnav
-```
-
-To view any specific log file, provide it via the command line:
-
-```
-lnav /var/log/syslog
-```
-
-Add timestamp in your log output using -t parameter
-
-```
-lnav -t /var/log/syslog
-```
-
-Here are some of the key switches of lnav
-
-```
--d file Write debug messages to the given file.-a Load all of the most recent log file types.-r Load older rotated log files as well.-t Prepend timestamps to the lines of data being read inon the standard input.-w file Write the contents of the standard input to this file.-c cmd Execute a command after the files have been loaded.-f path Execute the commands in the given file.-n Run without the curses UI. (headless mode)
-```

-What is Firefox ESR? How to Install it in Ubuntu?
-======
-
-The snap version of Ubuntu is not to your liking? Don’t like constantly changing things with every Firefox release? You can try the Firefox ESR version if you value stability over features.
-
-### What is Firefox ESR?
-
-Firefox ESR is a special edition of Firefox browser that doesn’t necessarily get new features monthly as the regular edition but it provides a stable and secure browsing experience. This is suitable for enterprises, organizations and institutes where stability and core features matter more than shiny new features.
-
-Think of Firefox ESR as the long-term stable release of Linux distributions. They do not necessarily get brand-new features but they get regular security and maintenance updates. This gives the users a familiar and stable environment.
-
-#### Why should you care for Firefox ESR?
-
-Firefox releases a new version almost every month. It contains security and feature updates.
-
-But some people may not like the inclusion and removal of features. If, after an update, you keep wondering where did certain settings go or do not like things that are different than before, Firefox ESR could be worth a try.
-
-Basically, if you value stability more than new features, Firefox ESR is for you. This is the same version of Firefox that ships with Debian, which is known for being one of the most stable distros you can get in the market.
-
-Let me show you how to get Firefox ESR on Ubuntu. **_You can have both Firefox and Firefox-ESR versions installed simultaneously. There is no visual difference in their logos so you have to pay attention to which Firefox version you are opening._**
-
-### Installing Firefox ESR in Ubuntu
-
-Before I jump to the installation part, let me share what’s the version difference between regular Firefox and Firefox-ESR. While writing,
-
-- Firefox is running at version **107.0-2**.
-- Firefox-ESR is currently having **102.5.0esr**.
-
-So if that’s fine for you, let’s look at the first method.
-
-#### Method 1: Install Firefox-ESR using PPA
-
-Firefox-ESR is not available in the default repository of Ubuntu, so you can use the PPA.
-
-PPA is nothing but a repository being maintained by individual techies or developers to have what the default repository does not.
-
-And if you want to learn more about PPA, I would recommend checking our other guide that explains [how you can use PPA on Linux.][1]
-
-Open your terminal and use the given command to add PPA for Firefox-ESR:
-
-```
-sudo add-apt-repository ppa:mozillateam/ppa
-```
-
-And press Enter to confirm you want to add PPA:
-
-![add firefox esr repository in ubuntu][2]
-
-Once done, you will have to update the repository index in Ubuntu to take effect from the changes:
-
-```
-sudo apt update
-```
-
-And now, you can install Firefox-ESR by using the given command:
-
-```
-sudo apt install firefox-esr
-```
-
-Next, you can use the given command to check the installed version of Firefox-ESR in your system:
-
-```
-firefox-esr -v
-```
-
-![check installed version of firefox esr in ubuntu][3]
-
-##### Uninstalling Firefox-ESR from Ubuntu
-
-If the ESR felt too outdated for your work or for any other reason you want to remove it from your system, you can follow the steps to remove the Firefox-ESR package and the repository.
-
-First, let’s remove the Firefox-ESR package using the following:
-
-```
-sudo apt remove firefox-esr
-```
-
-Now, you can use the given command to [remove PPA from Ubuntu][4]:
-
-```
-sudo add-apt-repository --remove ppa:mozillateam/ppa
-```
-
-And that’s it!
-
-#### Method 2: Install Firefox-ESR using Snap
-
-Love it or hate it, Snaps comes pre-configured on Ubuntu and I find using snaps a neat way of installing packages, especially when you want to avoid building them for source or using PPA.
-
-All you need to do to install Firefox-ESR using snaps is to follow the given command:
-
-```
-sudo snap install firefox --channel=esr/stable
-```
-
-![install firefox esr using snaps in ubuntu][5]
-
-##### Removing Firefox-ESR Snap
-
-To remove Firefox-ESR (snap package), use the [snap remove command][6]:
-
-```
-sudo snap remove firefox
-```
-
-And that’s it!
-
-### Wrapping Up
-
-I explained how to install Firefox-ESR in Ubuntu using multiple methods in this guide. I personally use Firefox-ESR instead of the regular version as I was having random crashes.
-
-Since I shifted to Firefox-ESR, things have been going rock-solid for me. And if you were having the same, you should give it a try.

-And thanks to some excellent software from developers, it has become easy for anyone to create video content and stream them over several popular platforms such as YouTube and Twitch. If you think about it, you see you are consuming more video content today while online than text-based content.
-
-So, in this post, we will list out some of the free software for Ubuntu and other Linux primarily that are easy to use for creating super interesting live streaming content for you and your businesses.
-
-### Top 5 Live Streaming Applications for Linux in 2022
-
-#### OBS Studio
-
-The first free application in this list is OBS Studio (also known as Open Broadcaster Software). It is a live streaming application with screencasting capabilities available for Linux, Windows and macOS.
-
-OBS Studio is the best one on this list because several reasons. The encoding is built-in, and it supports RTMP broadcasting, multiple sources, webcams, green-screen, capture cards and your application windows.
-
-The user interface is reasonably straightforward and feature-rich. You can get help from third-party developed plugins to extend their functionalities, such as – mixing live tweets from Twitter on your streaming media while live streaming. However, OBS does not support multi-bitrate streaming.

-
-### Closing Notes
-
-There are very few free and open-source live streaming applications available for Linux. However, several commercial live streaming applications are available, which may give you more options, quality, and support. But as I said, they may cost you some bucks. So, if you are new to the streaming world, you may want to get started with the above-listed free live streaming applications in Ubuntu or other Linux systems. I hope this article gives you ideas about which to use based on your need and get you started.

-How to Access UEFI Settings in Linux Systems
-======
-
-Want to check the boot order or the power settings at the firmware level? **You can access the UEFI settings by pressing the F2, F10 or Del buttons when your system boots**.
-
-The problem with this approach is that you may not know the exact key and must be alert about pressing those keys at the right time.
-
-![Mr. Bean][1a]
-
-If you don’t want to feel like Mr. Bean in the above Gif, you can access the UEFI settings from the [Grub bootloader][1] screen in Linux.
-
-![uefi firmware settings grub linux][2]
-
-You see this screen when you turn on your Linux system. Most Linux distributions like Fedora and Ubuntu use Grub and they allow you to access the UEFI settings from the Grub screen like this.
-
-What if you don’t see this screen or your distro doesn’t use Grub? There are still ways to access UEFI settings from within Linux.
-
-Before you see how to do that, please [ensure that your system uses UEFI][3].
-
-**_Another important thing. Your system will reboot into UEFI settings._** _You cannot access and modify the firmware settings from within an operating system._
-
-### Boot into UEFI settings from Linux
-
-This method will only work on Linux distros having systemd. This means this method will work on anything based on Ubuntu, Debian, Fedora, and any mainstream Arch-based distros, including Manjaro and EndeavourOS.
-
-It is still a good idea to [ensure that your Linux distro uses systemd][4]. Use the given command and if it returns systemd you are good to go:
-
-```
-ps --no-headers -o comm 1
-```
-
-![how to know if i am using systemd on linux?][5]
-
-Once you figure out that your distro is utilizing systemd, you can use the given command to boot into UEFI settings:
-
-```
-systemctl reboot --firmware-setup
-```
-
-Let me break down the used options first:
-
-- `reboot`: As its name suggest, it will reboot your system.
-- `--firmware-setup`: When this option is used with `reboot`, it will indicate to the system’s firmware to boot into the firmware setup interface.
-
-Yup, that was it! A single command and you will be kicked into UEFI settings. I know Windows allows [booting into UEFI firmware settings from within Windows][6]. It’s good to see something similar in Linux as well.
-
-#### Create a desktop shortcut to boot into UEFI settings (optional)
-
-If you often find yourself booting into the UEFI settings and don’t remember the command all the time, you can make your life easier by creating a desktop shortcut. This will let you boot into UEFI by clicking on desktop icon.
-
-_**Now, this is unnecessary and not required for most Linux users. Do it only if you feel the need for it. The method requires [editing files in the command line][7].**_
-
-First, use the given command to create a desktop shortcut file for UEFI settings:
-
-```
-sudo nano /usr/share/applications/uefi-reboot.desktop
-```
-
-And paste the following content in the file:
-
-```
-[Desktop Entry]
-Name=UEFI Firmware Setup (Reboot)
-Comment=Access the motherboard configuration utility
-Exec=systemctl reboot --firmware-setup
-Icon=system-restart
-Terminal=false
-Type=Application
-Categories=System;Settings;
-```
-
-![create a desktop shortcut to boot into uefi settings][8]
-
-Once done, [save the changes and exit from the nano][9] text editor.
-
-And now, you will find the shortcut for UEFI Firmware Setup in your system menu:
-
-![boot into uefi firmware from system menu][10]
-
-That’s it! A neat way to get into UEFI settings.
-
-### Wrapping Up
-
-The classic ways of accessing the boot settings may be a little inconvenient for some people. The grub screen may not show the UEFI option for older versions.
-
-And this is where the systemd method shines. I found this method a lifesaver when my system crashed and my function keys were not responding, which are necessary to boot into UEFI (that’s what I thought then!).
-
-I hope you find it equally helpful.

-Convert and Manipulate Images With ‘Converter’ GUI Tool in Linux
-======
-
-You can always [install ImageMagick][1] on your system to convert images, but not everyone likes to use the terminal for converting and manipulating images.
-
-So, what if you have a GUI app as a front-end to help with that? **Converter** is precisely that.
-
-It is a front-end to ImageMagick. So you do not need to use commands to convert and manipulate images.
-
-Note that most Ubuntu systems usually have ImageMagick pre-installed. You can always refer to our [installation guide][1] if you do not have it on your system.
-
-### Converter: A Graphical Front-end to ImageMagick
-
-![converter gui][2]
-
-It should not take a lot of effort to convert images. It is a simple task, and that is how it should be.
-
-I do not want to type a command to convert an image quickly. Hence, I prefer graphical tools that enable me to do things faster.
-
-[Converter][3] is an open-source graphical front-end that enables you to do that. It is a GTK4+libadwaita application.
-
-You can convert the images to various file formats that include **png, webp, jpeg, heif, heic, and bmp**. It is safe to say that you get support for the most popular image file formats. So, it should come in pretty handy.
-
-![file format converter][4]
-
-You can set a location to save all the files, and the converted images will automatically be stored at that location.
-
-![customize converter][5]
-
-You can also adjust an image’s quality, size, and background color. To access these options, click on “**More Options**” in the user interface before converting the image.
-
-![converter more options][6]
-
-The image size can be customized using its percentage, exact pixels, or ratio. For precise manipulation, changing the dimensions should help.
-
-If you want the image scaled to an extent, the percentage or ratio functionality should help you do that. You can also choose to add filters to your images.
-
-Overall, you get the basic options to re-size, convert, and optimize the image quality with Converter.
-
-You can also [tweak Nautilus][7] to have the [resize option in the right-click context menu][8]. It won’t be as versatile as this tool.
-
-### Install Converter on Linux
-
-Converter is available as a Flatpak on [Flathub][9] to install on any Linux distribution of your choice.
-
-Unfortunately, you do not get any binary packages to install on your Linux system. So, you might want to refer to our [Flatpak guide][10] to get it installed.
-
-```
-flatpak install flathub io.gitlab.adhami3310.Converter
-```
-
-You can explore more about it on its [GitLab page][3].
-
-_Do you have any suggestions to nifty tools like this for us to highlight next? Let us know in the comments._

-7 pro tips for using the GDB step command
-======
-
-A debugger is software that runs your code and examines any problems it finds. [GNU Debugger][1] (GBD) is one of the most popular debuggers, and in this article, I examine GDB's `step` command and related commands for several common use cases. Step is a widely used command but there are a few lesser known things about it which might be confusing. Also, there are ways to step into a function without actually using the `step` command itself such as using the less known `advance` command.

-Consider a simple example program:
-
-```
-#include
-
-int num() {
- return 2;
-}
-
-void bar(int i) {
- printf("i = %d\n", i);
-}
-
-int main() {
- bar(num());
- return 0;
-}
-```
-
-If you compile without the debugging symbols first, set a breakpoint on `bar` and then try to step within it. The GDB gives an error message about no line number information:
-
-```
-gcc exmp.c -o exmp
-gdb ./exmp
-(gdb) b bar
-Breakpoint 1 at 0x401135
-(gdb) r
-Starting program: /home/ahajkova/exmp
-Breakpoint 1, 0x0000000000401135 in bar ()
-(gdb) step
-Single stepping until exit from function bar,
-which has no line number information.
-i = 2
-0x0000000000401168 in main ()
-```
-
-### Stepi
-
-It is still possible to step inside the function that has no line number information but the `stepi` command should be used instead. Stepi executes just one instruction at a time. When using GDB's `stepi` command, it's often useful to first do `display/i $pc`. This causes the program counter value and corresponding machine instruction to be displayed after each step:
-
-```
-(gdb) b bar
-Breakpoint 1 at 0x401135
-(gdb) r
-Starting program: /home/ahajkova/exmp
-Breakpoint 1, 0x0000000000401135 in bar ()
-(gdb) display/i $pc
-1: x/i $pc
-=> 0x401135 : sub $0x10,%rsp
-```
-
-In the above `display` command, the `i` stands for machine instructions and `$pc` is the program counter register.
-
-It can be useful to use info registers and print some register contents:
-
-```
-(gdb) info registers
-rax 0x2 2
-rbx 0x7fffffffdbc8 140737488346056
-rcx 0x403e18 4210200
-(gdb) print $rax
-$1 = 2
-(gdb) stepi
-0x0000000000401139 in bar ()
-1: x/i $pc
-=> 0x401139 : mov %edi,-0x4(%rbp)
-```
-
-### Complicated function call
-
-After recompiling the example program with debugging symbols you can set the breakpoint on the `bar` call in main using its line number and then try to step into `bar` again:
-
-```
-gcc -g exmp.c -o exmp
-gdb ./exmp
-(gdb) b exmp.c:14
-Breakpoint 1 at 0x401157: file exmp.c, line 14.
-(gdb) r
-Starting program: /home/ahajkova/exmp
-Breakpoint 1, main () at exmp.c:14
-14 bar(num());
-```
-
-Now, let's step into`bar()`:
-
-```
-(gdb) step
-num () at exmp.c:4
-4 return 2;
-```
-
-The arguments for a function call need to be processed before the actual function call, so `num()` is expected to execute before `bar()`is called. But how do you step into the `bar` as was desired? You need to use the `finish` command and `step` again:
-
-```
-(gdb) finish
-Run till exit from #0 num () at exmp.c:4
-0x0000000000401161 in main () at exmp.c:14
-14 bar(num());
-Value returned is $1 = 2
-(gdb) step
-bar (i=2) at exmp.c:9
-9 printf("i = %d\n", i);
-```
-
-### Tbreak
-
-The `tbreak` command sets a temporary breakpoint. It's useful for situations where you don't want to set a permanent breakpoint. For example, if you want to step into a complicated function call like `f(g(h()), i(j()), ...)` , in such a case you need a long sequence of `step/finish/step` to step into `f` . Setting a temporary breakpoint and then using continue can help to avoid using such sequences. To demonstrate this, you need to set the breakpoint to the `bar` call in `main` as before. Then set the temporary breakpoint on `bar`. As a temporary breakpoint it is automatically removed after being hit:
-
-```
-(gdb) r
-Starting program: /home/ahajkova/exmp
-Breakpoint 1, main () at exmp.c:14
-14 bar(num());
-(gdb) tbreak bar
-Temporary breakpoint 2 at 0x40113c: file exmp.c, line 9.
-```
-
-After hitting the breakpoint on the call to `bar` and setting a temporary breakpoint on `bar`, you just need to continue to end up in `bar`.
-
-```
-(gdb) continue
-Continuing.
-Temporary breakpoint 2, bar (i=2) at exmp.c:9
-9 printf("i = %d\n", i);
-```
-
-### Disable command
-
-Alternatively, you could set a normal breakpoint on `bar` , continue, and then disable this second breakpoint when it's no longer needed. This way you can achieve the same results as with the `tbreak` with one extra command:
-
-```
-(gdb) b exmp.c:14
-Breakpoint 1 at 0x401157: file exmp.c, line 14.
-(gdb) r
-Starting program: /home/ahajkova/exmp
-Breakpoint 1, main () at exmp.c:14
-14 bar(num());
-(gdb) b bar
-Breakpoint 2 at 0x40113c: file exmp.c, line 9.
-(gdb) c
-Continuing.
-Breakpoint 2, bar (i=2) at exmp.c:9
-9 printf("i = %d\n", i);
-(gdb) disable 2
-```
-
-As you can see, the `info breakpoints` command displays `n` under `Enb`which means it’s disabled but you can enable it later if it’s needed again.
-
-```
-(gdb) info breakpoints
-Num Type Disp Enb Address What
-1 breakpoint keep y 0x0000000000401157 in main at exmp.c:14
-breakpoint already hit 1 time
-2 breakpoint keep n 0x000000000040113c in bar at exmp.c:9
-breakpoint already hit 1 time
-(gdb) enable 2
-(gdb) info breakpoints
-Num Type Disp Enb Address What
-1 breakpoint keep y 0x000000000040116a in main at exmp.c:19
-breakpoint already hit 1 time
-2 breakpoint keep y 0x0000000000401158 in bar at exmp.c:14
-breakpoint already hit 1 time
-```
-
-### Advance location
-
-Another option you can use is an `advance` command. Instead of `tbreak bar ; continue` , you can simply do `advance bar` . This command continues running the program up to the given location.
-
-The other cool thing about `advance` is that if the location that you try to advance to is not reached, GDB will stop after the current frame's function finishes. Thus, execution of the program is constrained:
-
-```
-Breakpoint 1 at 0x401157: file exmp.c, line 14.
-(gdb) r
-Starting program: /home/ahajkova/exmp
-Breakpoint 1, main () at exmp.c:14
-14 bar(num());
-(gdb) advance bar
-bar (i=2) at exmp.c:9
-9 printf("i = %d\n", i);
-```
-
-### Skipping a function
-
-Yet another way to step into the `bar,` avoiding `num`, is using the `skip` command:
-
-```
-(gdb) b exmp.c:14
-Breakpoint 1 at 0x401157: file exmp.c, line 14.
-(gdb) skip num
-Function num will be skipped when stepping.
-(gdb) r
-Starting program: /home/ahajkova/exmp
-Breakpoint 1, main () at exmp.c:14
-14 bar(num());
-(gdb) step
-bar (i=2) at exmp.c:9
-9 printf("i = %d\n", i);
-```
-
-To know which functions are currently skipped, `info skip` is used. The `num` function is marked as enabled to be skipped by `y`:
-
-```
-(gdb) info skip
-Num Enb Glob File RE Function
-1 y n n num
-```
-
-If `skip` is not needed any more it can be disabled (and re-enabled later) or deleted altogether. You can add another `skip` and disable the first one and then delete them all. To disable a certain `skip`, its number has to be specified, if not specified, each `skip`is disabled. It works the same for enabling or deleting a `skip`:
-
-```
-(gdb) skip bar
-(gdb) skip disable 1
-(gdb) info skip
-Num Enb Glob File RE Function
-1 n n n num
-2 y n n bar
-(gdb) skip delete
-(gdb) info skip
-Not skipping any files or functions.
-```
-
-### GDB step command
-
-Using GDB's `step` command is a useful tool for debugging your application. There are several ways to step into even complicated functions, so give these GDB techniques a try next time you're troubleshooting your code.

-Install open source solar power at home
-======
-
-You might have already given some thought to powering your home with solar. Solar photovoltaic panels, which convert sunlight directly into electricity, have fallen so far down in cost that it makes economic sense everywhere. That is why large companies have put in a lot of solar, and even the electric utilities have started installing massive solar farms—it simply costs less than antiquated fossil fuels. Like most homeowners, you would like to save money and eviscerate your electric bill, but you are probably cringing a bit at the upfront cost. To get a rough idea of the cost, a 5kW system that would power an average home installed at $3/W would cost about $15,000, while a larger home might need 10kW to offset all of their electricity purchases and cost $30,000. If you want batteries, double the cost (you don’t need batteries as most solar arrays connect to the grid, but if the grid goes down, so does your solar array until it is turned back on.) Paying for all your electricity for the next several decades is an investment, even if you save a lot of money.
-
-There is some good financial news. First, both the US and Canada have enacted a 30% tax credit for solar. This credit drops the price down to about $2/W. Second, [Opensource.com previously discussed][1] how you could get a free book, [_To Catch the Sun_][2], that walks you through how to design your own system (you will still need a certified electrician and inspections to attach it to the grid). If you are a little handy, you can cut the remaining cost by about 50%. These costs are primarily for materials, including solar panels, wiring, electronics, and racking. Amazingly, solar panel costs have dropped so low for small solar systems (like the ones for your house) the racking (mechanical structures that hold the solar panels up) can cost more than the panels!
-
-### Open source to the rescue again
-
-Applying the open source development paradigm to software results in faster innovation, better products, and lower costs. The same is true of open source hardware—and even in the relatively obscure area of photovoltaic racking. Nearly all commercial photovoltaic racking is made from proprietary odd aluminum extrusions. They cost a lot of money. If you have a bit of unshaded backyard, you have a few open source racking solutions to choose from.
-
-### Open source solar rack designs
-
-The first DIY solar rack design meets the following criteria: (1) made from locally-accessible renewable materials, (2) 25-year lifetime to match solar warranties, (3) able to be fabricated by average consumers, (4) able to meet Canadian structural building codes (if you live where there is no snow this is a bit overkill, but, hey, you might have other weather extremes like hurricanes to deal with), (5) low cost and (6) that it is shared using an open source license. [The open source wood-based fixed-tilt ground-mounted bifacial photovoltaic rack design][3] works throughout North America. The racking system saves from 49% to 77% compared to commercial proprietary racking. The racking design, however, is highly dependent on the cost of lumber, which varies worldwide.
-
-Check your local cost of wood before you dive into this open source design.
-
-![Non-tilting solar rack plans][4]
-
-If you are even more adventurous, you might consider this second design that allows you to change the tilt angle. The results of [the second study][5] show the racking systems with an optimal variable seasonal tilt angle have the best lifetime energy production, with 5.2% more energy generated compared to the fixed-tilt system (or 4.8% more energy, if limited to a maximum tilt angle of 60°). Both fixed and variable wooden racking systems show similar electricity costs, which are only 29% of that of proprietary commercial metal racking. The variable tilt rack provides the lowest cost option even when modest labor costs are included and also may provide specific advantages for applications such as [agrivoltaics][6] (i.e., you can garden underneath the panels and amazingly get increases in yields for shade-tolerant crops like lettuce). This design has been certified by [OSHWA with CERN-OHL-S-2.0 licenses][7].
-
-IMAGE
-
-![Tilt-adjustable solar racks][8]
-
-There is about 1kW for each of the 2 PV module racks shown. So a house would need about five of them. Both papers provide full calculations and step-by-step build instructions.
-
-As anyone with a solar system will tell you, getting a negative electricity bill is pretty rewarding. This happens if you size your system to meet all of your load and live in a net-metered part of the country. Please note that the electric utilities don’t pay you; the credit carries over until you use it in the winter.
-
-Have fun with a little open source solar!

-How to Update Flatpak Packages in Linux
-======
-
-I believe almost all Linux users keep their systems updated.
-
-But that update is usually for the default [package manager][1]. For example, [updating Ubuntu][2] often means updating all the APT packages.
-
-However, there are other packaging formats like Snap and Flatpak. The Snap applications get updated automatically but not the Flatpak ones.
-
-How do you update the Flatpak packages then? Well, you can update all the installed and updatable Flatpak packages using this command:
-
-```
-flatpak update
-```
-
-That’s quite simple. But let me discuss a few more things about updating Flatpak, such as:
-
-- Updating all or specific Flatpak packages
-- Updating Flatpak packages via Software Center
-
-Let’s start with the terminal method first.
-
-### Method 1: Using the terminal for updating Flatpak packages
-
-Let me first start with the most practical approach that you should also begin with.
-
-#### Update every outdated Flatpak package
-
-Updating the whole catalog of existing flatpak packages is quite easy.
-
-Enter the given command, and it will get you the list of outdated packages:
-
-```
-flatpak update
-```
-
-![3. update flatpak packages in linux][3]
-
-You just have to enter “Y” and press the Enter key, which will take care of every update.
-
-#### Updating specific Flatpak package
-
-To update specific packages, you’d need the list of the packages that can be updated. You used the same command you saw earlier.
-
-```
-flatpak update
-```
-
-![3. update flatpak packages in linux][4]
-
-Copy the name of the package you want to update from the output. Use the package name in the following fashion:
-
-```
-flatpak update package_name
-```
-
-For example, if you want to update Telegram, the following command will get the job done:
-
-```
-flatpak update org.telegram.desktop
-```
-
-![4. update specific package in flatpak][5]
-
-That’s it!
-
-### Method 2: Update Flatpak applications from the software center
-
-Distributions that come up with Flatpak buil-in support provide updates to Flatpak applications in the software center. Fedora and Linux Mint are such distributions.
-
-But if you are using Ubuntu, you’d need to add flatpak support to the GNOME software center:
-
-```
-sudo apt install gnome-software-plugin-flatpak
-```
-
-Once done, you will have two software centers in Ubuntu. That’s because the default software center is not GNOME’s but Snap Store.
-
-Open this new software center from the system menu:
-
-![1. open software center in ubuntu][6]
-
-Go to the `Updates` section and you will find the list of outdated packages. This includes both APT and Flatpak packages.
-
-![2. update flatpak from software center][7]
-
-From here, you can update all the packages at once, or you can be selective with what to update.
-
-### Wrapping Up
-
-Many Linux desktop users tend to forget to update the Flatpak packages as they are not included in the regular system updates.
-
-As Flatpak is a sandboxed packaging solution, you may not face any issues related to outdated packages, but you will miss out on new features and fixes for sure.
-
-This is why I recommend running the Flatpak update command once ever few weeks.
-
-I hope you like this quick little Flatpak tip helpful.

-Simplify your Linux PC with the PCManFM file manager
-======
-
-The PCMan File Manager, or PCManFM for short, is a fast and lightweight file manager that's full of features. It was developed for the [LXDE][1] desktop environment, but is a stand-alone application and can be used with the desktop or window manager of your choice.
-
-### Install PCManFM
-
-On Linux, you can probably find PCManFM in your software repository. For instance, on Fedora, Mageia, and similar:
-
-```
-$ sudo dnf install pcmanfm
-```
-
-On Debian, Elementary, and similar:
-
-```
-$ sudo apt install pcmanfm
-```
-
-![Image of the PCMan file manager.][2]
-
-PCManFM doesn't have to replace your desktop's file manager, but some distributions assume that when you install a "third party" file manager, you want it to take precedence over the default. Depending on the desktop you're using, there are different ways of setting your default file manager. Usually, it's in **System Settings** under **Default Applications**.
-
-If your desktop environment or window manager has no interface to select your default applications, you can set your preference in the `~/.local/share/applications/mimeapps.list` file. To designate a file manager as default, place it at the top of the `[Default Applications]` section, first specifying the file type and then the name of the application file (as it appears in `/usr/share/applications`) you want to use to open it:
-
-```
-inode/directory=myfilemanager.desktop;
-```
-
-### PCManFM
-
-If you're a fan of GNOME 2 or the Mate project's [Caja file manager][3], then PCManFM is a great alternative to consider. PCManFM is a lot like Caja in design, but it's not bound to the desktop in the way Caja is, so it's available even on the latest GNOME desktop.
-
-The default layout of PCManFM has a helpful toolbar near the top of the window, a side panel providing quick access to common directories and drives, and a status bar with details about your current selection. You can hide or show any of these elements using the **View** menu.
-
-### Tabs and panels
-
-PCManFM also uses tabs. If you've never used a tabbed file manager before, then think of a web browser and how it uses tabs to let you open multiple web pages in just one window. PCManFM can similarly open several directories in the same window.
-
-To transfer a file or folder from one tab to another, just drag the file's icon to the tab and hover. After a nominal delay, PCManFM brings the target tab to the front so you can continue your drag-and-drop operation. It takes some getting used to if you're not used to interacting with tabs in a file manager, but it doesn't take long, and it's a very powerful feature for decluttering your workspace.
-
-Another nice feature of the PCManFM interface is its ability to split a window into two panels. Each panel is effectively a tab, but each one only takes up half of the window.
-
-![Image of dual panels in PCMan.png][4]
-
-This makes dragging from one to the other just as easy and natural as dragging a file into a folder. I find it useful for comparing the contents of folders, too.
-
-### File management with PCMan
-
-PCManFM is a great little file manager with all the basic features you need on an everyday basis. It's a natural replacement for a file manager you might find too complicated, as well as a great option on [old computers][5] that might struggle with a file manager that's constantly drawing thumbnails and refreshing and generating animations. PCMan focuses on the core task of a file manager: managing files. Try it out on your Linux PC.

+How to Install the Minimalist ArchBang Linux Distro
+======
+
+ArchBang is a minimal and lightweight [Arch Linux based distribution][1]. It uses the i3 window manager. With its minimal nature, ArchBang can help you revive your old computer or low-end devices.
+
+There are two ways to install Arch Bang:
+
+- Using the guided installer script
+- Following Arch wiki
+
+No prizes for guessing that using the guided installer script will be easier to follow.
+
+In this tutorial, I’ll show you the steps for installing ArchBang with its text-based installer script.
+
+Please [check if your computer has UEFI or the legacy BIOS system][2]. Some steps are different for them.
+
+I have performed the demo in a virtual machine. And hence the wifi configuration part is not there. Internet connection is not mandatory here; you can also install it offline. You can connect to wifi from within the system after successfully installing ArchBang.
+
+Also, this method will remove any other operating system installed on your disk. Please be mindful of that.
+
+### Download ArchBang Live ISO
+
+To install ArchBang, you need the live ISO first.
+
+You can go to their [official website and download the required ISO][3], as shown in the below screenshot.
+
+![go to archbang iso images to download the iso file from sourceforge][4]
+
+It brings you to their Sourceforge page. Download the ISO, which is approximately 1.2 GiB in size.
+
+### Create the Live USB of ArchBang
+
+Once downloaded, you should make a bootable USB of ArchBang. You can [use software like Balena Etcher][5] to create it. It’s quite simple to use.
+
+Plug in your USB, browse to the downloaded ISO file and then hit the Flash button.
+
+![etcher flash][6]
+
+### Using text-based ArchBang installer
+
+ArchBang live ISO will bring you to the default i3 desktop with conky running.
+
+![archbang live iso home screen][7]
+
+You have two methods to start the installation process:
+
+- Press **Super + I** (as per desktop conky) to start installation directly.
+- Press **Super + T** to enter the terminal and use the command: `sudo abinstall`
+
+A terminal with several options will appear when you do the above step:
+
+![archbang installer][8]
+
+The above screenshot shows the main menu of ArchBang installer. You can select each section with the associated number.
+
+When you complete each category of the above installer, it will return to this menu and you can select the next category by pressing the corresponding number and Enter key.
+
+Also, the completed sections will be checked with an “x” mark.
+
+#### Step 1: Select / Set Partition
+
+On the new installer screen, enter “1” to start [partitioning the disk][9].
+
+Inside this, select the **Default** option. The installer has several tools to partition the disk, like cfdisk, fdisk, parted, etc. I used fdisk to do the job.
+
+##### Partitioning for Non-UEFI system
+
+Once the tool is selected, it will ask to choose the storage device. In my case, it was `/dev/sda` . Select the appropriate choice in your context.
+
+To start partitioning, enter “n” for a new partition. After that, select **Primary Partition.**
+
+![creating partition for non uefi system][10]
+
+For [non-UEFI systems][2], you can create one single root partition for all purposes. So, accept all the default values for “First Sector” and “Last Sector”. Then, press “w” to write the changes.
+
+On the next screen, you have to choose your filesystem and swap method. In this tutorial, I am using the EXT4 file system and Swap to File as the swap method.
+
+So set those according to the screenshot.
+
+![format the disk and select ext4 partition][11]
+
+##### Partitioning for UEFI system
+
+For UEFI users, you need to have two partitions, one EFI, with a 550 MB space, and another main root partition with the rest of the space (Swap as a file setting).
+
+Press n and select **Primary Partition.** Then select the Partition number as 1.
+
+Accept the default value for “First sector”. Now enter “+550M” as the value for “Last Sector”.
+
+Once again, press “n” and select **Primary Partition**. Accept the default value for the first and last sectors.
+
+![create two partitions for efi system][12]
+
+Press “t” to change the type and select the partition number “1” or `/dev/sda1`, whose type is to be changed from “Linux” to “EFI”.
+
+Select the partition type as EFI, as shown below:
+
+![change type of smaller partition to efi][13]
+
+Press “w” to write the changes. Then it will ask for filesystem selection. Here, you need to select the larger partition as the root partition (/dev/sda2, that is option 2 in the below screenshot).
+
+![select larger partition for root partition in efi system][14]
+
+Select EXT4 filesystem. This will again ask for mounting EFI partition.
+
+![select efi partition][15]
+
+In this step, you need to select the EFI partition at `/dev/sda1` and choose the mount point as `/boot/efi` . This will ask for format. Give consent by pressing “y”.
+
+Also, don’t forget to choose the swap to file option.
+
+#### Step 2: Start ArchBang installation
+
+This is pretty simple. Select the Install ArchBang option from the main menu by pressing the corresponding number (2 in this case). It will start the installation process.
+
+![installing archbang progress bar][16]
+
+You should wait for some time to complete the installation.
+
+#### Step 3: Set Hostname
+
+Once installation is completed, Select the 3rd option on the main menu, which is for setting the hostname. You need to enter a hostname.
+
+![provide hostname and press enter][17]
+
+#### Step 4: Set Location
+
+Location/Time Zone is typically mentioned in Zone/City format. I used Asia/Kolkata as the time zone.
+
+The installer provides the list of available zones and cities; you need to enter the number corresponding to your choice.
+
+![set time zone info][18]
+
+Also, set your location the same way.
+
+#### Step 5: Set Hardware Clock
+
+You have two options; Set Hardware Clock to UTC or Local Time.
+
+![set hardware clock time][19]
+
+There are two time standards:** localtime** and Coordinated Universal Time (UTC). The localtime standard depends on the current time zone, while UTC is the global time standard and is independent of time zone values.
+
+Enter your choice and press Enter key.
+
+#### Step 6: Set Locale
+
+Usually, you set the locale to en_US, if you are unsure what to do. That should be fine for most English-speaking users.
+
+If you want to use the operating system in some other language like French, Spanish, Dutch etc, you can choose the appropriate locale from the list.
+
+![set locale][20]
+
+#### Step 7: Desktop Keyboard Layout
+
+Similarly, most users should be fine with US keyboard. If you have some other keyboard (like French, or Italian), enter the appropriate choice from the available ones.
+
+![set desktop keyboard layout][21]
+
+#### Step 8: Configure Bootloader
+
+In ArchBang, you get GRUB2, Syslinux, or Systemd for the bootloader. To make it simple, I am selecting GRUB2 from the choice.
+
+![select grub2 as bootloader][22]
+
+Now, it will ask you to specify the method to install GRUB. Select **Automatic** and press enter.
+
+![select automatic grub][23]
+
+#### Step 9: Set Root Password
+
+Now, you should enter the root password. Select “Root Password” from the main menu.
+
+![enter and confirm root password][24]
+
+Here, enter and confirm the root password.
+
+#### Step 10: Create a New User
+
+Using a system with only a Root User is not secure. So, you should create a new user. In this installer, select the 10th option. Here, you should type a user name, password and confirm the password.
+
+![create user and password][25]
+
+Once done, press Enter to go to the main menu.
+
+#### Step 11: Finish configuration
+
+At this stage, you have reviewed all the configurations needed. You can now make it to effect by entering the letter “d” as shown in the screenshot below:
+
+![enter d option to finish the installation][26]
+
+This will ask permission to reboot your system.
+
+![press y to reboot your system to new archbang][27]
+
+Entering “y” will reboot your system to the newly installed ArchBang system.
+
+### Post Installation Tweaks
+
+Once rebooted, you will land in the same console. Probably there is no [display manager][28] installed. Here you should enter the username and password and press enter.
+
+![login to archbang through tty][29]
+
+This will bring you to the i3WM.
+
+![installed archbang with i3wm][30]
+
+Once installed, you need to do a couple of update tasks. **Connect to the internet first**.
+
+Firstly, you need to update the Pacman keys and archlinux-keyring.
+
+To do the same, open a terminal by pressing **Super + T** and run the following commands one by one:
+
+```
+sudo pacman-key –init
+sudo pacman-key –populate
+sudo pacman -Syyu archlinux-keyring
+```
+
+This will update system packages and keyrings. Reboot your system.
+
+Now, you should install a display manager. I prefer LightDM display manager. So open a terminal and enter the following command to install it:
+
+```
+sudo pacman -S lightdm lightdm-gtk-greeter
+```
+
+Once installed, use the following command to start the Lightdm service:
+
+```
+sudo systemctl enable lightdm.service
+```
+
+You will get a good and minimal login screen from the next reboot.
+
+![lightdm login screen in archbang][31]
+
+You can now enjoy ArchBang Linux according to your liking.
+
+### Wrapping Up
+
+ArchBang brings a good Arch Linux experience coupled with a not-so-hard installer and i3WM as the window manager.
+
+I understand that using a text-based installer like this one could be intimidating for some users. But then, it is [one of the joys of the Arch Linux][32] domain. It feels like a challenge and when you successfully install it, it gives you a sense of accomplishment.
+
+I have tried to detail all the steps with the necessary explanation. Please let me know if you face any issues or if you have any questions.

+A sysadmin's guide to Carbonio
+======
+
+[Carbonio Community Edition (Carbonio CE)][1] is an open source no-cost email and collaboration platform by Zextras. It provides privacy for organizations seeking digital sovereignty by using on-premises self-hosted servers. Using self-hosted servers offers a deeper level of control over infrastructure and data. However, it requires more attention to server configurations and infrastructure management to guarantee data sovereignty. Tasks done by system administrators play an important role in this matter. This makes administrative tasks a crucial part of achieving digital sovereignty, therefore, an administrative console dedicated to such tasks becomes extremely valuable to facilitate sysadmins' everyday jobs.
+
+This is why Zextras launched the first release of its own admin panel for Carbonio CE on October 2022. For Carbonio CE system administrators, it is the first step toward the creation of an all-inclusive admin console.
+
+In this article, I go into detail about the Carbonio CE Admin Panel and take a deeper look into what it can accomplish.
+
+![Image of the Carbonio admin panel.][2]
+
+### What is the Carbonio CE Admin Panel?
+
+The Carbonio CE Admin Panel is designed to assist the Carbonio CE system administrators with the most repetitive and frequent tasks such as user management and domain configuration. It is a browser-based application that runs on a particular port and is available for system administrators to use in production environments as soon as Carbonio CE is installed.
+
+### Why do you need the admin panel?
+
+Everything done in Carbonio CE Admin Panel can be done through the command-line interface as well. This raises the question: why might system administrators prefer using the admin panel rather than the command-line interface?
+
+Using the admin panel has its own obvious advantages such as:
+
+- Making repetitive activities much easier to perform
+- Saving system administrators' time monitoring servers
+- Providing a much easier learning process for junior system administrators
+
+Even though using the admin panel makes administrative tasks easier to perform, there is more to using this native user interface for Carboino CE. In essence, the Carbonio CE Admin Panel gives you the ability to monitor and manage your organization server from a single centralized location. Even when you're far away, you may still access your admin panel to check the status of servers and carry out various administrative activities.
+
+### Creating and managing user accounts
+
+Managing users has always been one of the most, if not the most, performed action by sysadmins. Therefore it should be an essential part of every administrative GUI available for system administrators. Suppose you, as the system administrator of the company have received some request by users to edit some information on their account. For instance, giving them access to some features, or your company has hired new employees, or some employees have left the company. All these scenarios require a sysadmin to manage user accounts frequently.
+
+Using the Carbonio CE Admin Panel you can simply go to **Domains > select a domain > Accounts** and select any account to modify, or press the **+** button to add a new account.
+
+![Image of the accounts Carbonio adminpanel.][3]
+
+### Creating and managing mailing lists
+
+Besides creating user accounts, a system administrator is often required to create different mailing lists that reflect the organizational structure of the company. Using mailing lists, users can simply send emails to a group of users by inserting the list address instead of every user address one by one.
+
+Creating mailing lists in Carbonio CE is extremely easy using the admin panel. You need to go to **Domains > select a domain > Mailing List > press the + button**. You can now use the wizard that opens up to create a mailing list.
+
+![Image of the Carbonio admin panel mailing list.][4]
+
+The essential steps to follow are:
+
+- Insert the name
+- Insert the mailing list address
+- Press **NEXT**
+- Insert the members
+- Press **CREATE**.
+
+You can follow the same path to edit mail lists created before.
+
+### Creating and managing domains
+
+Managing domains is another task frequently done by system administrators. Similar to accounts, creating a domain is very easy in the Carbonio Admin Panel. You only need to go to **Domains > select a domain > under the details** and find different entries to monitor the status of the domain. To create a new domain simply click on the **CREATE** button on the top bar and select **Create New Domain** and insert the necessary information such as:
+
+- Domain name
+- Maximum number of accounts and maximum email quota
+- Mail server where the domain is hosted
+
+![Image of the Carbonio admin domains panel.][5]
+
+### Creating and managing mailstore servers
+
+The Carbonio CE Admin Panel allows system administrators to manage different servers present in the infrastructure and provide them with different tools to configure them. To monitor a new mailstore server you can go to **Mailstores > Servers List** and find all the available mailstore servers in your infrastructure in a list (when just one server is installed, only one server is shown in this area).
+
+Under **Server Details**, you can select any of the available servers in the list and select **Data Volumes** to show more details of the storage volumes attached to it. While multiple volumes can be mounted simultaneously, only one primary volume, one secondary volume, and one index volume can be designated as active. You can add new volumes using the **NEW VOLUME +** button in the same section. You can also change the volume properties simply by clicking on them to open their detail window.
+
+![Image of the Carbonio admin panel volumes.][6]
+
+### Creating and managing classes of service
+
+Another scenario that can be facilitated with the help of the admin panel is creating classes of service (COS). After the installation, a system administrator might need to create different classes (groups) and assign different properties to them. This way, later in the process each user or a group of users can be easily nominated to a class of service in order to have access to the features and properties assigned to that specific COS.
+
+![Image of the Carbonio admin panel COS features.][7]
+
+To create a COS simply click on the **CREATE** button and select **Create New COS** or alternatively go to **COS** on the left panel and click on **CREATE NEW COS +**. You can then insert the name of the COS and define the different services available to this specific class.
+
+To edit a COS, go to **COS** on the left panel and select a COS from the dropdown menu at top of the list.
+
+You can define settings like quotas, the mail servers that can host accounts from this COS, or enable features for this COS. You can also define features for general features like Mail, Calendar, and Contacts. Additional customizable options include Tagging, Out of Office Reply, Distribution List Folders, and so on.
+
+![Image of the Carbonio admin panel classes of service preferences.][8]
+
+### Conclusion
+
+In this article, you saw a few scenarios in which the Carbonio CE Admin Panel saves you time and effort. The admin panel is an evolution of classical administrative tools in a new and centralized interface that gives the possibility of accessing different functionalities and monitoring tools from the same location.

+Battle of the Texts and the Unicode Savior
+======
+
+We all know how to type text on the keyboard. Don’t we?
+
+So, may I challenge you to type that text in your favorite text editor:
+
+![«Ayumi moved to Tokyo in 1993 to pursue her career» said Dmitrii][1]
+
+This text is challenging to type since it contains:
+
+- typographical signs not directly available on the keyboard,
+- hiragana Japanese characters,
+- the name of the Japanese capital written with a macron on top of the two letters “o” to comply with the Hepburn romanization standard,
+- and finally, the first name Dmitrii written using the Cyrillic alphabet.
+
+No doubt, writing such a sentence on early computers would have been simply impossible. Because computers used limited character sets, unable to let coexist several writing systems. But today such limitations are lifted as we will see in this article.
+
+### How do computers store text?
+
+Computers stores characters as numbers. And they use tables to map those numbers to the glyph used to represent them.
+
+For a long time, computers stored each character as a number between 0 and 255 (which fits exactly one byte). But that was far from being sufficient to represent the whole set of characters used in human writing. So, the trick was to use a different correspondence table depending on where in the world you lived.
+
+Here is the [ISO 8859-15][2] correspondence table commonly used in France:
+
+![The ISO 8859-15 encoding][3]
+
+But if you lived in Russia, your computer would have probably used the [KOI8-R][4] or [Windows-1251][5] encoding instead. Let’s assume that later was used:
+
+![The Windows-1251 encoding is a popular choice to store text written using the Cyrillic alphabets][6]
+
+For numbers lower than 128, the two tables are identical. This range is corresponding to the [US-ASCII][7] standard, some kind of minimum-compatible set between characters tables. But beyond 128, the two tables are completely different.
+
+For example, according to Windows-1251, the string _“said Дмитрий”_ is stored as:
+
+```
+115 97 105 100 32 196 236 232 242 240 232 233
+```
+
+To follow a common practice in computer sciences, those twelve numbers can be rewritten using the more compact hexadecimal notation:
+
+```
+73 61 69 64 20 c4 ec e8 f2 f0 e8 e9
+```
+
+If Dmitrii sends me that file, and I open it I might end up seeing that:
+
+```
+said Äìèòðèé
+```
+
+The file _appears_ to be corrupted. But it isn’t. The data— that is the _numbers_–stored in that file don’t have changed. As I live in France, my computer has _assumed_ the file to be encoded as ISO8859-15. And it displayed the characters _of that table_ corresponding to the data. And not the character of the encoding table used when the text was originally written.
+
+To give you an example, take the character Д. It has the numeric code 196 (c4) according to Windows-1251. The only thing stored in the file is the number 196. But that same number corresponds to Ä according to ISO8859-15. So my computer wrongly believed it was the glyph intended to be displayed.
+
+![When the same text file is written then read again but using a different encoding][8]
+
+As a side note, you can still occasionally see an illustration of those issues on ill-configured websites or in email send by [mail user agents][9] making false assumptions about the character encoding used on the recipient’s computer. Such glitches are sometimes nicknamed [mojibake][10]. Hopefully, this is less and less frequent today.

+
+### Unicode comes to save to the day
+
+I explained encoding issues when exchanging files between different countries. But things were even worst since the encodings used by different manufacturers for the same country were not always the same. You can understand what I mean if you had to exchange files between Mac and PC in the 80s.
+
+Is it a coincidence or not, the [Unicode][12] project started in 1987, led by people of Xerox and … Apple.
+
+The goal of the project was to define a universal character set allowing to _simultaneously_ use any character used in human writing within the same text. The original Unicode project was limited to 65536 different characters (each character being represented using 16 bits— that is two bytes per character). A number that has proven to be insufficient.
+
+So, in 1996 Unicode has been extended to support up to 1 million different [code points][13]. Roughly speaking, a “code point” a number that identifies an entry in the Unicode character table. And one core job of the Unicode project is to make an inventory of all letters, symbols, punctuation marks and other characters that are (or were) used worldwide, and to assign to each of them a code point that will uniquely identify that character.
+
+This is a huge project: to give you some idea, the version 10 of Unicode, published in 2017, defines over 136,000 characters covering 139 modern and historic scripts.
+
+With such a large number of possibilities, a basic encoding would require 32 bits (that is 4 bytes) per character. But for text using mainly the characters in the US-ASCII range, 4 bytes per character means 4 times more storage required to save the data and 4 times more bandwidth to transmit them.
+
+![Encoding text as UTF-32 requires 4 bytes per character][14]
+
+So besides the [UTF-32][15] encoding, the Unicode consortium defined the more space-efficient [UTF-16][16] and [UTF-8][17] encodings, using respectively 16 and 8 bits. But how to store over 100,000 different values in only 8 bits? Well, you can’t. But the trick is to use one code value (8 bits in UTF-8, 16 in UTF-16) to store the most frequently used characters. And to use several code values for the least commonly used characters. So UTF-8 and UTF-16 are _variable length_ encoding. Even if this has drawbacks, UTF-8 is a good compromise between space and time efficiency. Not mentioning being backward compatible with most 1-byte pre-Unicode encoding, since UTF-8 was specifically designed so any valid US-ASCII file is also a valid UTF-8 file. In a sense, UTF-8 is a superset of US-ASCII. And today, there is no reason for not using the UTF-8 encoding. Unless of course if you write mostly with languages requiring multi-byte encodings or if you have to deal with legacy systems.
+
+I let you compare the UTF-16 and UTF-8 encoding of the same string on the illustrations below. Pay special attention to the UTF-8 encoding using one byte to store the characters of the Latin alphabet. But using two bytes to store characters of the Cyrillic alphabet. That is twice more space than when storing the same characters using the Windows-1251 Cyrillic encoding.
+
+![UTF-16 is a variable length encoding requiring 2 bytes to encode most characters. Some character still requires 4 bytes though (for example][18]
+
+![UTF-8 is a variable length encoding requiring 1, 2, 3 or 4 bytes per character][19]
+
+### And how does that help for typing text?
+
+Well… It doesn’t hurt to have some knowledge of the underlying mechanism to understand the capabilities and limitations of your computer. Especially we will talk about Unicode and hexadecimal a little later. But for now… a little bit more history. Just a little bit, I promise…
+
+… just enough to say starting in the 80s, computer keyboard used to have a [compose key][20] (sometimes labeled the “multi” key) next to the shift key. By pressing that key, you entered in “compose” mode. And once in that mode, you were able to enter characters not directly available on your keyboard by entering mnemonics instead. For example, in compose mode, typing RO produced the ® character (which is easy to remember as an R inside an O).
+
+![compose key on lk201 keyboard][21]
+
+It is now a rarity to see the compose key on modern keyboards. Probably because of the domination of PCs that don’t make use of it. But on Linux (and possibly on other systems?) you can emulate the compose key. This is something that can be configured in the GUI on many desktop environments using the “keyboard” control panel: But the exact procedure varies depending on your desktop environment or even depending its version. If you changed that setting, don’t hesitate to use the comment section to share the specific steps you’ve followed on your computer.
+
+As for myself, for now, I will assume you use the default Shift+AltGr combination to emulate the compose key.
+
+So, as a practical example, to enter the LEFT-POINTING DOUBLE ANGLE QUOTATION MARK, you can type Shift+AltGr<< (you don’t have to maintain Shift+AltGr pressed when entering the mnemonic). If you managed to do that, I think you should be able to guess by yourself how to enter the _RIGHT-POINTING_ DOUBLE ANGLE QUOTATION MARK.
+
+As another example, try Shift+AltGr--- to produce an EM DASH. For that to work, you have to press the [hyphen-minus][22] key on the main keyboard, not the one you will find on your numeric keypad.
+
+Worth mentioning the “compose” key works in a non-GUI environment too. But depending if you use you use X11 or a text-only console, the supported compose key sequence are not the same.
+
+On the console, you can check the list of supported compose key by using the `dumpkeys` command:
+
+```
+dumpkeys --compose-only
+```
+
+On the GUI, compose key is implemented at Gtk/X11 level. For a list of all mnemonics supported by the Gtk, take a look at that page: [https://help.ubuntu.com/community/GtkComposeTable][23]
+
+### Is there a way to avoid relying on Gtk for character composition?
+
+Maybe I’m a purist, but I found somewhat unfortunate the compose key support being hard-coded in Gtk. After all, not all GUI applications are using that library. And I cannot add my own mnemonics without re-compiling the Gtk.
+
+Hopefully, there is support for character composition at X11-level too. Formerly, through the venerable [X Input Method (XIM)][24].
+
+This will work at lower-level than Gtk-based character composition. But will allow a great amount of flexibility. And will work with many X11 applications.
+
+For example, let’s imagine I just want to add the --> composition to enter the → character (U+2192 RIGHTWARDS ARROW), I would create a `~/.XCompose` file containing those lines:
+
+```
+cat > ~/.XCompose << EOT
+# Load default compose table for the current local
+include "%L"
+
+# Custom definitions
+ : U2192 # RIGHTWARDS ARROW
+EOT
+```
+
+Then you can test by starting a new X11 application, forcing libraries to use XIM as input method:
+
+```
+GTK_IM_MODULE="xim" QT_IM_MODULE="xim" xterm
+```
+
+The new compose sequence should be available in the application you launched. I encourage you to learn more about the compose file format by typing `man 5 compose`.
+
+To make XIM the default input method for all your applications, just add to your `~/.profile` file the following two lines. that change will be effective the next time you’ll open a session on your computer:
+
+```
+export GTK_IM_MODULE="xim"
+export QT_IM_MODULE="xim"
+```
+
+It’s pretty cool, isn’t it? That way you can add all the compose sequences you might want. And there are already a couple of funny ones in the default XIM settings. Try for example to press composeLLAP.
+
+Well, I must mention two drawbacks though. XIM is relatively old and is probably only suitable for those of us who don’t regularly need multi-bytes input methods. Second, when using XIM as your input method, you no longer can enter Unicode characters by their code point using the Ctrl+Shift+u sequence. What? Wait a minute? I didn’t talk about that yet? So let’s do it now:
+
+### What if there is no compose key sequence for the character I need?
+
+The compose key is a nice tool to type some characters not available on the keyboard. But the default set of combinations is limited, and switching to XIM and defining a new compose sequence for a character you will need only once in a lifetime can be cumbersome.
+
+Does that prevent you to mix Japanese, Latin and Cyrillic characters in the same text? Certainly not, thanks to Unicode. For example, the name あゆみ is made of:
+
+- the [HIRAGANA LETTER A (U+3042)][25]
+- the [HIRAGANA LETTER YU (U+3086)][26]
+- and the [HIRAGANA LETTER MI (U+307F)][27]
+
+I mentioned above the official Unicode character names, following the convention to write them in all upper cases. After their name, you will find their Unicode code point, written between parenthesis, as a 16-bit hexadecimal number. Does that remind you something?
+
+Anyway, once you know the code point of a character, you can enter it using the following combination:
+
+- Ctrl+Shift+u, then XXXX (the _hexadecimal_ code point of the character you want) and finally Enter.
+
+As a shorthand, if you don’t release Ctrl+Shift while entering the code point, you won’t have to press Enter.
+
+Unfortunately, that feature is implemented at software library level rather than at X11 level. So the support may be variable among different applications. In LibreOffice, for example, you have to type the code point using the main keyboard. Whereas Gtk-based application will accept entry from the numeric keypad as well.
+
+Finally, when working at the console on my Debian system, there is a similar feature, but requiring instead to press Alt+XXXXX where XXXXX is the code point of the character you want, but written in _decimal_ this time. I wonder if this is Debian-specific or related to the fact I’m using the en_US.UTF-8 locale. If you have more information about that, I would be curious to read you in the comment section!
+
+| GUI | Console | Character |
+| :- | :- | :- |
+| Ctrl+Shift+u3042Enter | Alt+12354 | あ |
+| Ctrl+Shift+u3086Enter | Alt+12422 | ゆ |
+| Ctrl+Shift+u307FEnter | Alt+12415 | み |
+
+### Dead keys
+
+Last but not least, there is a simpler method to enter key combinations that do not rely (necessarily) on the compose key.
+
+Some keys on your keyboard were specifically designed to create a combination of characters. Those are called [dead keys][28]. Because when you press them once, nothing seems to happen. But they will silently modify the character produced by the next key you will press. This is a behavior inspired from mechanical typewriter: with them, pressing a dead key imprinted a character, but will not move the carriage. So the next keystroke will imprint another character at the same position. Visually resulting in a combination of the two pressed keys.
+
+We use that a lot in French. For example, to enter the letter “ë” I have to press the ¨ dead key followed by the e key. Similarly, Spanish people have the ~ dead key on their keyboard. And on the keyboard layout for Nordic languages, you can find the ° key. And I could continue that list for a very long time.
+
+![hungary dead keys][29]
+
+Obviously, not all dead keys are available on all keyboard. I fact, most dead keys are NOT available on your keyboard. For example, I assume very few of you— if any— have a dead key ¯ to enter the macron (“flat accent”) used to write Tōkyō.
+
+For those dead keys that are not directly available on your keyboard, you need to resort to other solutions. The good news is we’ve already used those techniques. But this time we will use them to emulate dead keys. Not “ordinary” keys.
+
+So, a first option could be to generate the macron dead key by using Compose- (the hyphen-minus key available on your keyboard). Nothing appears. But if after that you press the o key it will finally produce “ō”.
+
+The list of dead keys that Gtk can produce using the compose mode can be found [here][30].
+
+A different solution would use the Unicode COMBINING MACRON (U+0304) character. Followed by the letter o. I will leave the details up to you. But if you’re curious, you may discover this leads to a very subtlely different result, rather than really producing a LATIN SMALL LETTER O WITH MACRON. And if I wrote the end of the previous sentence in all uppercase, this is a hint guiding you toward a method to enter ō with fewer keystrokes than by using a Unicode combining character… But I let that to your sagacity.
+
+### Your turn to practice!
+
+So, did you get it all? Does that work on your computer? It’s your turn to try that: using the clues given above, and a little bit of practice, now you can enter the text of the challenge given in the beginning of this article. Do it, then copy-paste your text in the comment section below as proof of your success.
+
+There is nothing to win, except maybe the satisfaction of impressing your peers!

+
+Use Django to send emails with SMTP
+======
+
+Numerous professions utilize simple mail transfer protocol (SMTP) to deliver emails to their end users. SMTP also retrieves messages, though that has not been its primary use case. Open source frameworks like Django, a Python-based web framework, allows more control for sending emails using functions and expressions.
+
+This article shows how to configure an SMTP server and send emails in Django using SMTP.
+
+### Project setup and overview
+
+Before proceeding, this tutorial requires a code editor (such as [VS Code or Codium][1]) on your preferred device.
+
+Start by creating a new directory using the command in the terminal:
+
+```
+mkdir exampledirectory
+```
+
+Then change into the directory using the command:
+
+```
+cd exampledirectory
+```
+
+Within the newly created directory, create a [virtual environment][2] using the built-in venv module in the command terminal:
+
+```
+python -m venv
+```
+
+This command creates a virtual environment within the folder created earlier. To activate it, use the following command in the terminal:
+
+On Linux and Mac:
+
+```
+source .virtenv/bin/activate
+```
+
+On Windows:
+
+```
+\Scripts\activate
+```
+
+### Creating a Django project
+
+After activating the virtual environment, proceed to install the Django package from [pip][3]:
+
+```
+pip install django
+```
+
+Create a new Django project:
+
+```
+python -m django startproject NewEmailProject
+```
+
+This command creates a project with the name `NewEmailProject`. To run the project, head to the project directory (`NewEmailProject`) and run the server:
+
+```
+python manage.py runserver
+```
+
+Open the link for the developmental server in a browser. You see the Django homepage with release notes.
+
+### Configuration for sending emails
+
+Next, open the `settings.py` file (in the `NewEmailProject` folder) to customize configurations for sending emails using Django.
+
+Scroll to the end of the code and update the file with the following code:
+
+```
+EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
+EMAIL_HOST = 'smtp.yourserver.com'
+EMAIL_USE_TLS = False
+EMAIL_PORT = 465
+EMAIL_USE_SSL = True
+EMAIL_HOST_USER = 'your@djangoapp.com'
+EMAIL_HOST_PASSWORD = 'your password'
+```
+
+Change the value of the `EMAIL_HOST` depending on your email client. Here are the acceptable values for common email clients:
+
+- **Gmail:**`smtp.gmail.com`
+- **Outlook:**`smtp-mail.outlook.com`
+- **Yahoo:**`smtp.mail.yahoo.com`
+
+You can change the `EMAIL_PORT` or leave 465 as the default.
+
+You can use the secure socket layer (SSL) and transport socket layer (TSL) interchangeably as they specify connection security.
+
+To figure out other custom configurations for your email server, check out the full [Django Project documentation][4].
+
+### SMTP email backend
+
+The `EMAIL_BACKEND` expression helps determine the most suitable backend when sending emails through the Django SMTP server. This variable points to `smtp.EmailBackend`, which receives all the parameters needed for sending emails. It tells Django to send the email to the recipient email using SMTP and not to the console.
+
+### Sending emails with SMTP
+
+When the environment is set up and `settings.py` is updated, you can send emails in Django. You can use an HTML form that sends a post request of the necessary information needed for sending an email.
+
+Create a Django application for sending emails:
+
+```
+python manage.py startapp mail
+```
+
+Next, open the `settings.py` file and add the Django application (mail) to the `INSTALLED_APPS` list:
+
+```
+INSTALLED_APPS = [
+"django.contrib.admin",
+"django.contrib.auth",
+"django.contrib.contenttypes",
+"django.contrib.sessions",
+"django.contrib.messages",
+"django.contrib.staticfiles",
+"mail"]
+```
+
+### Send mail function
+
+In the mail application's `views.py` file, start by importing the `EmailMessage` and `get_connection` from `django.core.mail`:
+
+```
+from django.core.mail import EmailMessage, get_connection
+```
+
+The `EmailMessage` class is responsible for creating the email message itself. The `get_connection()` function returns an instance of the email backend specified in `EMAIL_BACKEND`.
+
+Now create a function that accepts a `POST` request, which contains form data submitted from the client side. Followed by the `get_connection()` functions parameters containing the email configurations created in the project `settings.py` file.
+
+Next, import the settings:
+
+```
+from django.conf import settings
+```
+
+This import allows access to the email configurations created in the `settings.py`. Next, create the variables:
+
+```
+subject, recipient_list,
+```
+
+Then you can `message`, and store the corresponding attributes used in the HTML form. The `email_from` variable contains the sender email, which is obtained from `EMAIL_HOST_USER` in the `settings.py` file.
+
+After the variables are processed, the `EmailMessage` class sends an email using the `sends()` method, and then closes the connection. The `send_email()` function renders the `home.html` file containing the email form.
+
+You can create a templates folder within your mail application and store the HTML files within that folder:
+
+```
+from django.core.mail import EmailMessage, get_connectionfrom django.conf import settingsdef send_email(request):
+ if request.method == "POST":
+ with get_connection(
+ host=settings.EMAIL_HOST,
+ port=settings.EMAIL_PORT,
+ username=settings.EMAIL_HOST_USER,
+ password=settings.EMAIL_HOST_PASSWORD,
+ use_tls=settings.EMAIL_USE_TLS
+ ) as connection:
+ subject = request.POST.get("subject")
+ email_from = settings.EMAIL_HOST_USER
+ recipient_list = [request.POST.get("email"), ]
+ message = request.POST.get("message")
+ EmailMessage(subject, message, email_from, recipient_list, connection=connection).send()
+
+ return render(request, 'home.html')
+```
+
+This is a bootstrap form for generating a message:
+
+```
+
+```
+
+This form sends a post request to the `send_email()` function. This processes the form data and sends the email to the recipients.
+
+Now open the `urls.py` file in the `NewEmailProject` folder to create the homepage URL. Update the `urlpattern` list by adding the code `path("", send_email)` .
+
+### Sending email to multiple recipients
+
+To specify multiple recipients when sending the same email, create a new function called `send_emails` within the `views.py` file and modify the send function code:
+
+```
+def send_emails(request):
+ if request.method == "POST":
+ with get_connection(
+ host=settings.EMAIL_HOST,
+ port=settings.EMAIL_PORT,
+ username=settings.EMAIL_HOST_USER,
+ password=settings.EMAIL_HOST_PASSWORD,
+ use_tls=settings.EMAIL_USE_TLS
+ ) as connection:
+ recipient_list = request.POST.get("email").split()
+ subject = request.POST.get("subject")
+ email_from = settings.EMAIL_HOST_USER
+ message = request.POST.get("message")
+ print(type(recipient_list))
+ EmailMessage(subject, message, email_from, recipient_list, connection=connection).send()
+
+ return render(request, 'send_emails.html')
+```
+
+For the `recipient_list` variable, I'm using the Python `split()` method to convert the recipients email string to list so that I can email all of them.
+
+Next, create another HTML file called `send_emails.html` in the templates folder and use the same form code for the `home.html` file within it.
+
+To specify multiple email recipients, use a space between each email address:
+
+```
+first@gmail.com second@gmail.com third@gmail.com
+```
+
+You should also update the `urlpattern` list by adding the code:
+
+```
+path("send-emails/", send_email)
+```
+
+### Sending HTML emails
+
+You can also send HTML emails with Django using a slightly modified version of the `send_email` function:
+
+```
+html_message = '''
this is an automated message
'''
+msg = EmailMessage(subject, html_message, email_from,recipient_list, connection=connection)
+msg.content_subtype = "html"
+msg.send()
+```
+
+### Sending emails with attachment
+
+To include attachment to mails, create a variable and put it in the file path in a string like this:
+
+```
+attachment = "mail/templates/example.png"
+```
+
+Then, move the `EmailMessage` function to a variable and call the `attach_file` method followed by the `send` method:
+
+```
+msg = EmailMessage(subject, message, email_from, recipient_list, connection=connection)
+msg.attach_file(attachment)
+msg.send()
+```
+
+### Django email libraries
+
+This guide on sending emails in Django would not be complete if I didn't mention the email libraries that are available to users. Here are some noteworthy email libraries.
+
+- **Django mailer** is a Django app for queuing as it saves emails in a database and sends the mail out at a designated time.
+- **Django templated email** aims to send templated emails. It offers features like configurable template naming and location, template inheritance, and adding recipients to the CC and BCC lists.
+- **Anymail** allows the use of an email service provider (ESP). By using `django.core.mail`, it provides a sustained API that avoids tying your code to a single ESP.
+
+### Emailing with Django
+
+Sending emails in Django can sound daunting, but it's as simple as creating a virtual environment. You can add Django to the environment and create an email backend. Finally, you can set up an HTML template. Give it a try.

+
+Drupal 10 is worth a fresh look
+======
+
+The popular Drupal open source content management system (CMS) reaches a significant milestone when version 10 is released on December 14. Personally, I think Drupal X sounds way cooler, but so far, my calls to name it that haven't gotten much traction. I enlisted the help of my friend Aaron Judd of [Northern Commerce][1] to give us a sense of how cool Drupal X could look:
+
+![New Drupal 10 racing 10 logo][2]
+
+### What's a Drupal, anyway?
+
+Drupal is an open source CMS and development framework. While other CMS options focus on simple long-form content (think blogs) or entirely free-form content (like in Wix or Squarespace), Drupal has made a name for itself in handling more complex content architectures, in multiple languages, with robust content governance. Drupal sites (like this site, Opensource.com!) benefit from a strong role-based access control (RBAC) system, unlimited custom roles and workflows, and a powerful and extensible media library.
+
+Here's a rundown for anyone who hasn't kept tabs on what's coming in the newest major version.
+
+### A fresh face
+
+Most Drupal sites use custom themes to give them a unique look and feel. Still, the initial experience you have when installing a CMS matters. In Drupal, themes define the look and feel of a site, and you can use different themes for public and administrative experiences. Until recently, the Bartik and Seven themes had been the default face of Drupal for more than a decade. To put that in context, when Bartik was released, the most popular browser in the world was Internet Explorer 8. A lot has changed since then, particularly around best practices for building websites.
+
+In fact, a significant change in Drupal 10 will be the removal of support for Internet Explorer (IE), which is itself no longer supported by Microsoft and hasn't seen major updates since 2013. That may not sound like an improvement, but continued support for IE kept the community from adopting modern markup and styling. For example, thanks to being unencumbered by support for legacy browsers, Drupal 10 includes a new responsive grid layout that's so innovative it got a writeup in [CSS Tricks][3].
+
+![Responsive grid configuration][4]
+
+The new faces of Drupal are two brand new themes: Olivero for visitors and Claro for admins. In addition to being fresh and modern designs, both were developed with accessibility as a top priority.
+
+### Improvements under the hood
+
+More than a decade ago, the Drupal community decided to "Get Off the Drupal Island." That meant adopting solutions shared across popular projects and frameworks instead of ones developed and maintained exclusively by the Drupal community. Today Drupal leverages a variety of projects and libraries whose names will be familiar to open source developers who have never touched Drupal: Symfony, Composer, CKEditor, Twig, Nightwatch, and more.
+
+That has brought a variety of powerful capabilities to Drupal and allowed it to contribute back to those solutions, benefitting a broader set of developers. It has also become a determining factor for the cadence of Drupal's major version releases.
+
+To illustrate, consider that Drupal 7 was released in early 2011. Drupal 8 was released almost five years later, towards the end of 2015. Drupal 9 was released in June of 2020, with a key motivator being the move to supported versions of underlying dependencies and removing deprecated code. And now, roughly two and half years later, we're already planning to release Drupal 10. This new major version will leverage updated versions of PHP, Symfony, and Composer, among others.
+
+### An all-new editor
+
+An upgrade of particular note is the move to CKEditor 5. Although notionally an incremental update, under the hood CKEditor 5 was completely rewritten, much the same as the transition from Drupal 7 to 8. In addition to a sleeker interface, CKEditor 5 has the potential for exciting new capabilities, such as real-time collaboration. Drupal's CKEditor integration for version 5 has already been augmented with a number of UI enhancements. For example, media placed within content can be configured using an overlaid toolbar ribbon instead of needing to launch a modal dialog to access these settings. Also, the styles dropdown now includes a preview of each type available.
+
+![Real-time collaboration][5]
+
+### A look ahead
+
+Earlier in 2022, Drupal creator and project lead Dries Buytaert announced a focus on "ambitious site builders." This means that while the community will continue to work on making the developer experience better in general, moving forward there is a particular focus on making it easier to create engaging experiences in Drupal without having to write code or use command-line tools. Three strategic initiatives embody this new focus: Automatic Updates, the Project Browser, and Recipes.
+
+**Automatic Updates** will reduce the total cost of ownership for Drupal sites and help them be more secure by ensuring they always have the latest core security patches. This will be a major benefit for site owners and Drupal development teams everywhere. However, judging by personal experience, Wednesday night pizza sales may take a hit (traditionally, the Drupal security team releases updates on the third Wednesday of the month). There is now a stable release of Automatic Updates as a contrib module. Work has begun to move this into Drupal core, so all Drupal sites will eventually be able to leverage this capability.
+
+The **[Project Browser][6]** makes Drupal sites easier to build, maintain, and evolve by allowing site builders to search and browse through a subset of Drupal's vast catalog of available modules, prefiltered to the site's Drupal version, for security, stability, and more. A site builder can select, download, and install a module without leaving the site's web interface. In fact, there's an "app store" like interface meant to promote the most popular modules available that are compatible with the current site's version of Drupal. While other CMS options have had similar offerings, this advancement means you don't need to sacrifice ease-of-use to take advantage of the power of Drupal. Also, all of the thousands of modules listed are 100% free.
+
+For many years Drupal has had a concept of distributions. These are opinionated versions of Drupal designed to meet specific use cases such as media publishing, fundraising, intranet portals, and more. While distributions have proven an excellent way to accelerate initial development, in practice, they have been known to require significant work to maintain and create extra work for site owners during maintenance. The **Recipes** initiative aims to make more granular, composable functionality available when building a site. Want to add a staff directory, events calendar, or locations map to your site? In the future, this will be as easy as installing a recipe and then customizing it to meet your site's specific needs.
+
+### It's an exciting time to try Drupal
+
+Drupal 10 is the culmination of work contributed by thousands of dedicated and talented community members worldwide. If you're not already using Drupal, we hope you'll try it out for your next project. There's a common saying among Drupalists: "Come for the code, stay for the community."

+Experience Linux desktop nostalgia with Rox
+======
+
+Rox-Filer is an open source file manager for Linux, once intended for the defunct Rox desktop but now a streamlined application for any window manager or desktop. There hasn't been much activity on the Rox project since 2014, and even then it is mostly in maintenance mode. And that's part of Rox-Filer's charm. In a way, Rox-Filer is a snapshot of an old desktop style that was progressive for its time but has given way to a more or less standardized, or at least conventional, interface.
+
+### Install Rox-Filer
+
+On Linux, your distribution's software repository may have Rox available for install. For instance, Debian packages it:
+
+```
+$ sudo apt install rox-filer
+```
+
+If your Linux distribution doesn't package Rox-Filer but you want to try it out, you can [compile from source][1] by downloading the [source code][2], installing its build dependencies, and then compiling:
+
+```
+$ sudo dnf install gtk2-devel libSM-devel \
+ shared-mime-info glade-libs xterm
+$ wget https://codeload.github.com/rox-desktop/rox-filer/zip/refs/heads/master
+$ unzip rox*zip
+$ cd rox-filer-master
+$ ./ROX-Filer/AppRun
+```
+
+### Configuring Rox
+
+The Rox file manager is based on the look and feel of RISC OS, an operating system developed by Acorn in Cambridge England (the same group responsible for the popular Arm microprocessor). Today, there's an [open source RISC OS][3] you can install on a Raspberry Pi, but for now, Rox is close enough.
+
+Rox has a simple layout. It has no menu bar, but there's a toolbar across the top, and the file panel is at the bottom.
+
+![Image of the Rox file manager.][4]
+
+As with the KDE Plasma Desktop, the default action of a single click in Rox is to open an item, whether it's a folder or a file. Unfortunately, no version of Rox, either packaged or compiled directly from the source, seems to be completely integrated with the mimetype definitions of the modern Linux desktop. For instance, Rox on CentOS renders an error when I click on even a basic text file, while the packaged version of Rox on Debian opens a plain text file but not a JPEG or archive file. You can fix this by setting a **Run Action** in the right-click context menu.
+
+![Setting a run action in the Rox file manager.][5]
+
+Setting a run action can have broad definitions, so you don't have to set a separate run action for JPEG, PNG, WEBP, and all other image types, instead set the same run command for all mimetypes starting with `image`.
+
+Once you set that, you're ready to manage files with Rox.
+
+### Navigation
+
+You can navigate through your file system using the arrow icon in the top toolbar. The **Up** arrow takes you to the parent directory of your current location (in other words, the folder your current folder is in). To descend into a folder, click on it.
+
+### Refreshing the view
+
+Rox may not redraw the screen for every action, so sometimes you may need to prompt it to refresh. Click the **Circle** arrow in the Rox toolbar to refresh your current location's contents.
+
+### Copy or move a file
+
+There are two ways to copy or move a file in Rox. First, you can launch a second Rox window and drag and drop files from one window to the other. When you do, you're prompted to copy, move, or link the item you've dropped.
+
+Alternatively, you can right-click an item and open the **File** submenu from the context menu. In the **File** submenu, choose **Copy** and then enter the destination path for the item you want to move or copy. After you've confirmed that the file has successfully been copied to the target location, you can optionally select the item again, choosing **Delete** from the **File** menu.
+
+### Options
+
+You can customize some aspects of Rox by selecting **Options** from the right-click menu. This brings up a Rox configuration screen that's admittedly only partially relevant to Rox. The Rox options assume you're running a window manager, like [Windowmaker][6] which provides a traditional dock (or "pinboard" in Rox terminology). I wasn't able to get the pinboard options to work on [Fluxbox][7], my preferred window manager, or Windowmaker. In both cases, the window manager handled iconified windows, and I wasn't able to configure Rox to override the control. It's possible that I wasn't drastic enough in some of my configurations, but considering that Linux window managers are very capable of managing iconified windows, the pinboard mechanism of Rox isn't a vital feature (and probably not as flexible as the window manager's options).
+
+The other options, however, still work as expected. For instance, Rox by default resizes its window size to fit the contents of a folder. When you change from a directory containing twelve items to a directory containing just three, Rox shrinks its footprint. I find this jarring, so I chose the **Never automatically resize** option, forcing Rox to stay whatever size I set.
+
+### Window commands
+
+Some of my favorite features are four menu items hidden away at the bottom of the **Window** submenu in the right-click context menu. They are:
+
+- **Enter path**: Enter an arbitrary path and change directory to it.
+- **Shell command**: Enter an arbitrary shell command and execute it.
+- **Terminal here**: Open a terminal at your current location.
+- **Switch to terminal**: Open a terminal at your current location, and close the Rox.
+
+I love options that allow for quick navigation or quick commands, so it's nice to have these close at hand.
+
+### Oldies
+
+Rox is a "blast from the past," whether or not you've ever used RISC OS or something like it. Rox represents a style of digital file management and even desktop configuration that just doesn't quite exist anymore. I've run Fluxbox, on and off again, at work and at home for the past decade, and I love manually configuring menus and configuration files. However, most of the Linux desktop has moved on from the conventions Rox relies upon. It's not impossible to make Rox fully functional, but it would take a lot of work, and most of what you'd be configuring are already provided by modern window managers and desktops. Even so, Rox is fun to use and experience. It's a great demonstration of how flexible a traditional Linux desktop setup was (and still can be, if you use only a window manager), and much of its charm is in its simplicity. I can't imagine a file manager today not having a dedicated move function, but Rox dares to force you to copy and delete instead. It's a different kind of file manager, and it might not be the one you use all day every day, but it's something you have to try if you miss, or literally missed, the "old days" of the Linux (or RISC OS) desktop.

+
+Best Screen Recorders for Wayland in Linux [Compared & Tested]
+======
+
+**Here’s a list of screen recorders which work in Wayland currently in most modern Linux distributions.**
+
+![][1]
+
+Modern Wayland protocol is used by default in most frontrunner Linux distributions, such as Ubuntu and Fedora. However, this X.Org successor comes with work for the app developers to re-platform their app for Wayland because Wayland is more secure and follows modern standards.
+
+Linux legacy applications, those written with X.Org in mind, don’t work well in most cases unless it is modified.
+
+Screen recorder apps fall into that category. There are many popular screen recorders which were developed for X.Org – doesn’t work anymore in Wayland.
+
+However, few of them work. In this list, I will walk you through a few that I tested in the Wayland session. And they work well.
+
+### Best screen recorder apps for Wayland in Linux distros
+
+#### 1. Kooha
+
+The first on this list is Kooha, written in GTK and supports X11 and Wayland. It’s a fast and simple screen recorder for the GNOME desktop. This application is one of the best GNOME apps that provides hassle-free recording experiences. This utility supports hardware acceleration, a timer, multiple sources as input and many advanced features. Here’s a summary:
+
+- Option to select monitor for multiple displays or any window
+- Hardware accelerated encoding (disabled by default; enable it via settings)
+- Option to record the area of a screen
+- Record mic and computer sound together
+- Delay timer for records
+- Option to choose the frame rate
+- Support for WebM, mp4, gif, Mkv file types
+
+![Kooha - Best Screen Recoder for GNOME][2]
+
+![Kooha Settings][3]
+
+Installing Kooha is easy using Flatpak. [Set up your system for Flatpak & Flathub][4] and run the following command to install it.
+
+```
+flatpak install io.github.seadve.Kooha
+```
+
+We tested it in the latest Ubuntu 22.10 and Fedora 37 with Wayland session, it works flawlessly.
+
+**More details about Kooha**
+
+- [Home page][5]
+- [Source code][6]
+
+#### 2. GNOME screen recorder
+
+The second in the list is GNOME Shell’s built-in screen recorder. It’s part of the GNOME’s new screenshot utility which you can launch by searching “screenshot” in the application menu.
+
+GNOME Screen recorder provides you option to record the entire screen or a rectangular portion. In addition, you have the option to record the cursor as well.
+
+However it only supports recording to webM format. And you can’t do a delayed start of your recording.
+
+You don’t need to install anything extra to use this. Since it comes by default with GNOME desktop.
+
+Use the keyboard shortcut `CTRL+SHIFT+ALT+R` to launch it. And select your option, then hit the record button.
+
+The recordings saved at ~/home/Videos/Screencasts.
+
+![GNOME Screen recorder][7]
+
+#### 3. OBS Studio
+
+The popular free and open-source streaming application OBS Studio recently started supporting Wayland. Although it is primarily used for live streaming, but it’s screen recording feature actually works in Wayland and you can use it.
+
+Since its a professional grade software, you can take advantage of it’s recording feature. In addition, you can also record the sound from the mic of your system while recording the screen.
+
+Installing OBS Studio is easy with Flatpak. [Set up your system for Flathub][4] and install it using the following command.
+
+```
+flatpak install com.obsproject.Studio
+```
+
+Note: OBS Studio need FFmpeg to run. We have a guide [here][8], if you want to install FFmpeg.
+
+After you launch OBS Studio, click on + sign under Sources to add source. Then select “Screen capture..”. And then click ok.
+
+![Screen capture option][9]
+
+![recording in OBS Studio in Wayland][10]
+
+After you stop the recording, it is saved at your ~/home directory.
+
+**More details about OBS Studio**
+
+- [Home page][11]
+- [Source code][12]
+
+#### 4. vokoscreenNG
+
+The vokoscreenNG is a little different screen recording app which is totally underrated. It’s an old application and supports window capture, rectangular caption. In addition, it also support audio capture alongside screen, system tray control, magnifying glass, countdown, timer and many cool features.
+
+Recently, an experimental Wayland support introduced which you can try out. It works fairly well. Currently it supports webm, m4, mkv, mov and avi formats for Wayland. However, audio recording is not yet available for Wayland sessions.
+
+You can download the pre-compiled executable for Linux distros which require no installation from the below link. And run.
+
+[Download][13]
+
+![vokoscreenNG][14]
+
+**More details about vokoscreenNG**
+
+- [Home page][15]
+
+#### 5. Wayfarer
+
+The final screen recorder in this list is Wayfarer, based on GTK4. It currently supports all the modern protocols such as Wayland, Pipewire with wireplumber. It’s simple user interface supports screen recording with audio capture. You can also select a portion of your desktop or the entire screen for recording.
+
+Furthermore, you can select the frame rate, select mouse capture and have the ability to delay the recording. Currently it supports webm, mp4 and mkv formats.
+
+![Wayfarer screen recorder for Linux][16]
+
+However, it is currently available in Arch User repository (AUR) for Arch Linux. You can setup any AUR helper such as Yay and install it using the following command.
+
+```
+yay -S wayfarer-git
+```
+
+**More details about Wayfarer**
+
+[Home page & source code][17]
+
+### Other excellent screen recorders which are currently not working with Wayland
+
+Other than the above list, there are some excellent screen recorders available for X.Org which is currently broken in Wayland. As per my test in Ubuntu 22.10 and Fedora 37 wayland session, none of these works. You can only see a black screen in the recording file. I hope they get fixed in coming days and become compatible with Wayland.
+
+- [Peek][18] (may work with XWayland backend)
+- [Simple screen recorder][19]
+- [Blue Recorder][20] (supports Wayland but is currently broken)
+
+### Wrapping Up
+
+From my personal experience, Wayland is faster and better. Since many modern distros are moving towards Wayland, you must change your workflow with replacement apps. I hope this list of screen recorders in Wayland helps you pick the one that suits you best.
+
+Do let me know if you know of any other apps of a similar category which work with Wayland.

+
+How to Switch from Debian Stable to Testing
+======
+
+If you are looking for the most stable Linux distribution, sure, Debian is the right choice.
+
+Especially if you are planning to use it on servers.
+
+But, on the desktop side, things are a bit different. I mean, you are given packages that are at least a year old and support for new-age hardware is even worse.
+
+So what do you do in those cases, Well, you can use Debian testing!
+
+But before jumping to the explanation part, let’s briefly understand Debian testing.
+
+### What is Debian Testing?
+
+Debian offers you 3 variants of Debian:
+
+- Debian stable (what you get by default from their homepage).
+- Debian testing (has **newer packages** and breaks less often than Debian unstable).
+- Debian unstable (has the most recent packages and is **considered the most fragile of all**).
+
+So Debian testing can be considered a sweet spot between stability and fresh packages.
+
+I’ve been playing around with Debian testing for some time and haven’t faced any issues.
+
+In fact, many Debian users prefer the testing variant over the stable version. Despite the name testing, it is pretty usable.
+
+But still, **I would recommend you to experiment with this on VM,** try using it with your primary tools and if things go well, you can apply those changes in the main system.
+
+### Switch from Debian stable to Debian testing
+
+**_Warning: You can not downgrade from Debian testing to Debian stable, as installer scripts and installation tools are only designed to replace the older version with the new one._**
+
+Also, I would recommend [using timeshift to create a backup][1] before applying the shown steps on your main machine.
+
+First, update the existing packages using the given command:
+
+```
+sudo apt update && sudo apt upgrade -y
+```
+
+Next, make a copy of original `sources.list` file:
+
+```
+sudo cp /etc/apt/sources.list sources.list.backup
+```
+
+Now, let’s start with the first step.
+
+#### Step 1: Edit sources.list file
+
+There are two ways of editing `sources.list` file. Either you can manually alter the current release name with `testing` or you can [use the sed command][2] to get your job done.
+
+And I’m going with a 2nd one to make the whole process easier. You just have to use the given command, and it will replace `bullseye` with `testing` for you:
+
+```
+sudo sed -i 's/bullseye/testing/g' /etc/apt/sources.list
+```
+
+Now, open your terminal and use the given command to open `sources.list` files:
+
+```
+sudo nano /etc/apt/sources.list
+```
+
+And comment out the lines having `security.debian.org` and anything that ends with `-updates` as shown below:
+
+![comment out security sources][3]
+
+If you are using nano as I do, you can press `Alt + /` to jump to the end of the line. And then you have to add the following line:
+
+```
+deb http://security.debian.org testing-security main
+```
+
+![2. add line to keep track of testing in debian][4]
+
+And [save the changes and exit from the nano][5] text editor.
+
+#### Step 2: Update the Repository and install new packages
+
+Now, update the repository index, and it will show you a massive update pending:
+
+```
+sudo apt update
+```
+
+![update repository in linux][6]
+
+Now, you can use the given command, and it will get you the most recent packages:
+
+```
+sudo apt upgrade
+```
+
+Sit back and relax as it is going to take a while.
+
+Once done, it will present you with the list of changes made as you switched from Debian stable to testing:
+
+![packages that are updated when switched to debian testing][7]
+
+You can read if you want or you can **just press q** to proceed further.
+
+Now, it will show you the message that some of the libraries installed on your system needs to restart. Press the **TAB** key, and it will select the **OK** option, and then press **Enter:**
+
+![libraries needs to be restarted after update][8]
+
+Next, it will ask you whether you want to restart services during the package upgrade. Here you have a choice. As I’m doing this for desktop usage only, I will go with `YES`:
+
+![restart services during package upgrades without asking?][9]
+
+Once done, you can reboot your system and then use the following command to have full effect from the changes you’ve just made:
+
+```
+sudo apt full-upgrade
+```
+
+Now, reboot your system, and you’ll have the most recent packages. Such as **I was running GNOME 43** when I got into the system:
+
+![running gnome 43 in debian][10]
+
+### Wrapping Up
+
+In this tutorial, I explained how you could switch from Debian stable to Debian testing. I hope this will be helpful to you.
+
+And if you face any issues or have any queries, let me know in the comments.

+Why Drupal is the future of content strategy
+======
+
+As a long-time advocate for open source and a contributor to Drupal, I spend a lot of time thinking about how organizations can leverage the platform. I've been thinking about Drupal's position in the larger digital ecosystem and how it compares to the other options on the market. And how Drupal can lean more on its strengths when planning out the strategy for a new project.
+
+### How Drupal fits into the digital landscape
+
+In 2022, putting a site online can be as fast as the time it takes to make a coffee. This is made possible because websites have many similar features and there's usually no need to build one from scratch. When I started my career, frameworks like Ruby on Rails were appealing because of their flexibility. But I quickly learned that the lack of standard solutions for common things like multilingual content, media management, and workflows, meant that each project required a huge investment in custom development.
+
+On the other hand, web builders that have emerged over the last ten years, like Wix and Squarespace offer the dream of "drag-and-drop" website construction and customizable templates. But in reality, their flexibility is very surface-level. They don't offer enough flexibility to build a solid content model, create an experience, or provide the level of content compliance that large organizations need.
+
+This is where Drupal stands out, providing both powerful functionality out-of-the-box, and the tools to build out custom functionality on top of that content.
+
+### Drupal, the content management system
+
+When I started using Drupal 15 years ago, it was described as a content management system. And it is, as it gives content editors the power to log in and manage content, rather than relying on a webmaster or a web developer to do it.
+
+But there was also the promise that site builders could update not just the content, but the content model. Site builders could extend Drupal using configuration instead of writing code. This set it apart from the frameworks that were out at the time. From years of teaching people Drupal, I can tell you that there's a certain amount of joy and empowerment that people get when they realize how much they can do through the Drupal admin UI.
+
+At its core, this is still Drupal's strength. You can control not just the content, but how content is organized. The fact that taxonomy and localization are baked into Drupal's content model, gives a huge advantage over other systems that have a more limited concept of content.
+
+### Drupal, the platform
+
+Shortly after adopting Drupal as our agency's technology of choice, I started calling it a platform. As an ambitious 20-something, I was keen to build more than nice-looking content-rich websites. The ambition was to create more powerful tools to organize the flow of information. This includes integrating Drupal with other systems to build functionality and workflows around your content. You can also create content synchronizations between a CRM and Drupal. Finally, you can search interfaces that allow you to search diverse content sources and filter content in new ways.
+
+The fact that Drupal is so adaptable to these architectures distinguishes it immediately from other CMSs. When talking to large organizations, teams of developers or IT leaders see the benefit of using a technology that is so flexible and adaptable to functional needs.
+
+### Drupal, the digital experience platform
+
+While these attributes are still very compelling, Drupal is now referred to as a digital experience platform (DXP). Its main difference from the proprietary DXPs of the world is that it's open. It doesn't ship with a stack of integrated technologies but rather lets you decide what your stack will be. Whether it's for marketing integrations or multi-channel experiences, you can decide how content feeds into and out of Drupal. This flexibility is one of Drupal's strengths. But it can be a challenge when pitching Drupal against other DXPs that come with a complete marketing toolset.
+
+Marketing folks often look for a packaged solution. And while an agency can package Drupal with a stack of tools, it's hard for Drupal to market this type of ready-to-go solution.
+
+### Drupal's strength as a content strategy platform
+
+So how does Drupal position itself when talking to marketers? Drupal's core strength is still its flexible content architecture. This means that it's an ideal platform for implementing a content strategy and content governance plan. These are two things that plenty of organizations are missing. They are also the two reasons for marketers to adopt a platform like Drupal.
+
+### Better content strategy with Drupal
+
+While Drupal can already be adapted to the content strategy of any organization, it doesn't mean that every Drupal website has a strong content strategy. Drupal implementers have to proactively make choices that prioritize the needs of content and content editors. This means doing things like:
+
+- Organizing content around user needs, not organizational structure
+- Structuring content to be reusable, adaptable, personalized, translatable
+- Integrating content with digital services by making content available via API
+- Setting up tools so that content compliance is checked systematically
+
+Meanwhile, beyond the website, organizations need to use best practices to prioritize their content strategy practice. This means:
+
+- Empowering communicators and treating content editors as first-class users
+- Sharing best practices for web publishing across the organization
+- Creating a clear, actionable content governance plan
+- Using tools like the digital asset management (DAM) tool that fosters content governance
+- Creating a smooth flow of content and feedback between content experts and users
+
+With new expectations of platforms to handle personalization and faster cycles for re-branding or implementing a completely new marketing strategy, it's more important than ever for your website to be a tool to help your content strategy. If you're looking for ways to orient your practice around a strong content strategy, here are some places to start:
+
+- Get content editors involved in the process when launching a new web project
+- Build [documentation][1] that's driven by content needs, not just technology. Use real content examples in your documentation and talk about the "why" of the content.
+- Prioritize ongoing content governance rather than just relying on big projects to revamp your content every 3-5 years
+- Invest in cleaning up legacy content instead of migrating content as-is when you do invest in a website redesign
+- Invest in the content editor experience, something that Drupal facilitates and continues to invest in, but still takes active effort to do for each project
+
+To sum up, Drupal is already a CMS and a DXP. But this is beside the point. There is a need to leverage Drupal's capabilities towards creating a strong content strategy to really get the most out of the platform.
+
+_This article is based on the author's talk at DrupalCon Portland: [Future of content management: using Drupal as a content strategy platform][2]._

+
+Enjoy two-panel file management on Linux with far2l
+======
+
+Far2l is a port of the Windows text-based file manager **Far**. And to be clear, that's a lower-case **L** (as in "Linux") not a number **1**. It runs in the terminal and is designed around a plug-in structure, enabling compatibility with SSH, WebDAV, NFS, and more. You can compile and run far2l on Linux, Mac, and BSD, or Far on Windows.
+
+### Install far2l
+
+Far2l is currently in beta, so you're unlikely to find it in your Linux distribution's software repository. However, you can [compile it from source][1] by downloading cloning its [Git repository][2]:
+
+```
+$ git clone --depth 1 https://github.com/elfmz/far2l.git
+```
+
+You can browse through the source code to see all of its different components. The main source files are in `utils/src`:
+
+```
+SharedResource.cpp
+StackSerializer.cpp
+StringConfig.cpp
+StrPrintf.cpp
+TestPath.cpp
+Threaded.cpp
+ThreadedWorkQueue.cpp
+TimeUtils.cpp
+TTYRawMode.cpp
+utils.cpp
+WideMB.cpp
+ZombieControl.cpp
+```
+
+The file `ZombieControl.cpp` works to [mitigate a zombie apocalypse][3] (at least, in terms of processes), the file `ThreadedWorkQueue.cpp` helps speed processes along by using threading. Far2l isn't just built for extensibility, it's built responsibly!
+
+Assuming you've already prepared your system for compiling code, as described in the [compiling from source][1] article, you must also install some development libraries required by far2l. On Fedora, CentOS, OpenMandriva, and Mageia, the minimal list is:
+
+- wxGTK3-devel
+- spdlog-devel
+- xerces-c-devel
+- uchardet-devel (your repository may not have this one, but there's a workaround)
+
+On Debian, the minimal list is:
+
+- libwxgtk3.0-gtk3-dev
+- libuchardet-dev
+- libspdlog-dev
+- libxerces-c-dev
+
+Use [CMake][4] to prepare the makefiles:
+
+```
+$ mkdir build
+$ cd !$
+$ cmake .. -DUSEUCD=no
+```
+
+The `-DUSECD=no` option is required only if you don't have the development libraries for `chardet` installed. If you do, then you can omit that option.
+
+Finally, compile the code and install far2l to a temporary location:
+
+```
+$ make -j$(nproc --all)
+$ mkdir ~/far2l
+$ make install DESTDIR=~/far2l
+```
+
+If you prefer to install it to your system instead of to a temporary directory, then omit the `DESTDIR=~/far2l` option.
+
+To launch far2l, invoke the binary stored in the `bin` subdirectory of your install path. For instance:
+
+```
+$ ~/far2l/local/bin/far2l
+```
+
+### Using far2l
+
+When you first launch far2l, it creates a configuration directory in `~/.config` and prompts you to choose what font you'd like to use. On my system, 16 pt font size was the default, and anything less than that was impossible to read. I used the open source Fantasque Mono Regular as my font, but any monospace font ought to work.
+
+Far2l is a two-panel file manager, meaning that the default view has a place to display two separate directories. At launch, both directories happen to be your home directory. To maximize the amount of screen space used for listing files, far2l uses two columns in each panel, and you can use the **Left** and **Right** arrows to change from one column to the other.
+
+In the right column, you can also use the **Right** arrow to move "down" the list of files by one screen. In the left column, use the **Left** arrow to move "up" the list of files by one screen.
+
+![Image of the far2l file manager.][5]
+
+This navigation takes some getting used to, especially if you're used to terminal file managers that only use the **Right** arrow to descend into a directory. However, once you get used to far2l's navigation, you're likely to appreciate the added speed you gain from this simple pagination.
+
+### Open a file or folder
+
+To open a folder, select a folder in your file list and press the **Return** key. This causes the active panel to change to a view of that directory. The inactive panel doesn't change, so it's not uncommon for far2l to always be showing two different directories at the same time. That's a feature of the two-panel file manager design, although it can take some getting used to if you're not in the habit of splitting windows.
+
+After you've moved into a directory, you can move back into its parent folder by selecting the double dots (`..`) at the top of the file listing and pressing **Return**.
+
+To open a file, select a folder in your file list and press the **Return** key. The file opens according to your desktop's mimetype preferences.
+
+### Panel and window navigation
+
+To move from one panel to another, press the **Tab** key.
+
+The fun thing about far2l is that its file listing is actually a layer over the top of your terminal. To hide the file listing temporarily, and to reveal it once it's gone, press **Ctrl+O** (that's the letter `O` not the digit zero).
+
+You can also adjust how much of your terminal the file panels take up. Press **Ctrl+Up** and **Ctrl+Down** to adjust the vertical size of the file panels.
+
+Make no mistake, though, you're not just suspending far2l when you access the terminal underneath. This isn't your usual terminal, it's a far2l terminal that interacts with the file manager and adds a few features to your standard terminal experience. For example, the [`find` command][6] gains graphical auto-completion.
+
+![Image of far2l responsive terminal.][7]
+
+### Copying and moving files
+
+All the usual file management functions are available within far2l are available with function keys. These are listed along the bottom of the far2l window. There are lots of options for some of the actions, which is either over-complex or really really powerful, depending on your preference.
+
+![Image of far21 move options.][8]
+
+### Exiting far2l
+
+To close far2l, type `exit far` into the command prompt at the bottom of the far2l window.
+
+### Far out
+
+Far2l is a dynamic and responsive text-based file manager. If you're a fan of classic two-panel file managers, then you'll feel at home with far2l. Far2l provides an interesting and novel interpretation of a terminal, and if you don't try far2l for its two-panel file management, you should at least try it for its terminal.

+
+5 reasons to love Linux GNOME Files
+======
+
+The GNOME desktop is a common default desktop for most Linux distributions and, as with most operating systems, you manage your data on GNOME with software called a file manager. GNOME promotes a simple and clear naming scheme for its applications, and so its file manager is called, simply, Files. Its intuitive interface is simple enough that you forget what operating system you're using altogether. You're just using a computer, managing files in the most obvious way. GNOME Files is a shining example of thoughtful, human-centric design, and it's an integral part of modern computing. These are my top five favorite things about GNOME Files, and why I love using it.
+
+### 1. Intuitive design
+
+![THe GNOME Files file manager is an intuitive and friendly application.][1]
+
+As long as you've managed files on a computer before, you basically already know how to use GNOME Files. Sure, everybody loves innovation, and everybody loves seeing new ideas that make the computer world a little more exciting. However, there's a time and a place for everything, and frankly sometimes the familiar just feels better. Good file management is like breathing. It's something you do without thinking about what you're doing. When it becomes difficult for any reason, it's disruptive and uncomfortable.
+
+GNOME Files doesn't have any surprises in store for you, at least not the kind that make you stop what you thought you were doing in order to recalculate and start again. And my favorite aspect of the "do it the way you think you should do it" design of GNOME Files is that there isn't only one way to accomplish a task. One thing I've learned from teaching people how to do things on computers is that everyone seems to have a slightly different workflow for even the simplest of tasks, so it's a relief that GNOME Files accounts for that.
+
+When you need to move a file, do you open a second window so you can drag and drop between the two? Or do you right-click and Cut the file and then navigate to the destination and Paste the file? Or do you drag the file onto a button or folder icon, blazing a trail through directories as they open for you? In GNOME Files, the "standard" assumptions usually apply (insofar as there are standard assumptions.)
+
+### 2. Space saver
+
+If you manage a lot of files for a lot of the time you're at your computer, you're probably familiar with just how much screen real estate a file manager can take up. Many file managers have lots of buttons across several toolbars, a menu bar, and a status bar, such that just one file manager window takes up a good portion of your screen. To make matters worse, many users prefer to open several folders, each in its own window, which takes even more space.
+
+GNOME Files tends to optimize space. What takes up three separate toolbars in other file managers is in a single toolbar in GNOME Files, and that toolbar is what would traditionally be the window title bar. In the top bar, there's a forward and back button, file path information, a view settings button, and a drop-down menu with access to common functions.
+
+![The GNOME Files toolbar has just the essential buttons, and in a compact space.][2]
+
+### 3. Other locations
+
+Not all operating systems or file managers make it so you can interact with your network as naturally as you can interact with your own computer. Linux has a long tradition of viewing the network as just another computer, and in fact, the name "GNOME" was an acronym for "GNU Network Object Model Environment."
+
+In GNOME Files, it's trivial to open a folder on a computer you're not sitting in front of. Whether it's a server in a data center or just your office desktop while you're relaxing in your lounge with a laptop, the **Other Locations** bookmark in the GNOME Files side panel allows you to access files as if they were on your hard drive.
+
+![It's easy to connect to remote systems through GNOME Files.][3]
+
+To use it, you enter the file sharing protocol you want to use, along with the username and IP address of the computer you want to access. The `ssh://` protocol is most common between Linux or Unix machines, while `smb://` is useful for an environment with [Windows machines][4], and `dav://` is useful for applications running on the Internet. Assuming the target computer is accessible over the protocol you're using, and that its [firewall is set correctly][5] to permit you to pass through it, you can interact with a remote system as naturally as though they were on your local machine.
+
+### 4. Preferences
+
+Most file managers have configuration options, and to be fair GNOME Files actually doesn't give you very many choices compared to others. However, the options that it does offer are, like the modes of working it offers its users, the "standard" ones. I'm misusing the word "standard" intentionally: There is no standard, and what feels standard to one person is niche to someone else. But if you like what you're experiencing with GNOME Files under normal circumstances, and you feel that you're its intended audience, then the configuration options it offers are in line with the experience it promotes. For example:
+
+- Sort folders before files
+- Expand folders in _list view_
+- Show the **Create link** option in the contextual menu
+- Show the **Delete Permanently** option in the contextual menu
+- Adjust visible information beneath a filename in _icon view_
+
+That's nearly all the options you're given, and in a way it's surface-level choices. But that's GNOME Files. If you want something with more options, there are several very good alternatives that may better fit your style of work. If you're looking for a file manager that just covers the most common use cases, then try GNOME Files.
+
+### 5. It's full of stars
+
+I love the concept of metadata, and I generally hate the way it's _not_ implemented. Metadata has the potential to be hugely useful in a pragmatic way, but it's usually relegated to specialized metadata editing applications, hidden from view and out of reach. GNOME Files humbly contributes to improving this situation with one simple feature: The gold star.
+
+In GNOME Files, you can star any file or folder. It's a bit of metadata so simple that it's almost silly to call it metadata, but in my experience, it makes a world of difference. Instead of desperately running [find][6] command to filter files by recent changes, or re-sorting a folder by modification time, or using [grep][7] to find that one string I just know is in an important file, I can star the files that are important to me.
+
+Making plans for the zombie apocalypse all day? Star it so you can find it tomorrow when you resume your important work. After it's over and the brain-eaters have been dealt with, un-star the folder and resume normal operation. It's simple. Maybe too simple for some. But I'm a heavy star-user, and it saves me several methods of searching and instead reduces "what was I working on?" to the click of a single button.
+
+### Install GNOME Files
+
+If you've downloaded a mainstream Linux distribution, then chances are good that you already have GNOME and GNOME Files installed. However, not all distributions default to GNOME, and even those that do often have different desktops available for download. The development name of GNOME Files is `nautilus`, so to find out whether you have GNOME Files installed, open a terminal and type `nautilus &` and then press **Return**. If you see this error, you don't have GNOME Files available:
+
+```
+bash: nautilus: command not found...
+```
+
+To install GNOME Files, you must install the GNOME desktop. If you're happy with your current desktop, though, that's probably not what you want to do. Instead, consider trying [PCManFM][8] or [Thunar][9].
+
+If you're interested in GNOME, though, this is a great reason to try it. You can probably install GNOME from your distribution's repository or software center.

+Use my Groovy color wheel calculator
+======
+
+Every so often, I find myself needing to calculate complementary colors. For example, I might be making a line graph in a web app or bar graphs for a report. When this happens, I want to use complementary colors to have the maximum "visual difference" between the lines or bars.
+
+Online calculators can be useful in calculating two or maybe three complementary colors, but sometimes I need a lot more–for instance, maybe 10 or 15.
+
+Many online resources explain how to do this and offer formulas, but I think it's high time for a Groovy color calculator. So please follow along. First, you might need to install Java and Groovy.
+
+### Install Java and Groovy
+
+Groovy is based on Java and requires a Java installation as well. Both a recent/decent version of Java and Groovy might be in your Linux distribution's repositories. Or you can install Groovy by following the instructions on the above link.
+
+A nice alternative for Linux users is [SDKMan][1], which can get multiple versions of Java, Groovy, and many other related tools. For this article, I'm using SDK's releases of:
+
+- Java: version 11.0.12-open of OpenJDK 11
+- Groovy: version 3.0.8
+
+### Using a color wheel
+
+Before you start coding, look at a real color wheel. If you open [GIMP (the GNU Image Manipulation Program)][2] and look on the upper left-hand part of the screen, you'll see the controls to set the foreground and background colors, circled in red on the image below:
+
+![Controls to set foreground and background colors][3]
+
+If you click on the upper left square (the foreground color), a window will open that looks like this:
+
+![Set foreground color][4]
+
+If it doesn't quite look like that, click on the fourth from the left button on the top left row, which looks like a circle with a triangle inscribed in it.
+
+The ring around the triangle represents a nearly continuous range of colors. In the image above, starting from the triangle pointer (the black line that interrupts the circle on the left), the colors shade from blue into cyan into green, yellow, orange, red, magenta, violet, and back to blue. This is the color wheel. If you pick two colors opposite each other on that wheel, you will have two complementary colors. If you choose 17 colors evenly spaced around that wheel, you'll have 17 colors that are as distinct as possible.
+
+Make sure you have selected the **HSV** button in the top right of the window, then look at the sliders marked H, S, and V, respectively. These are **h**ue, **s**aturation, and **v**alue. When choosing contrasting colors, the hue is the interesting parameter.
+
+Its value runs from zero to 360 degrees; in the image above, it's 192.9 degrees.
+
+You can use this color wheel to calculate the complementary color to another manually–just add 180 to your color's value, giving you 372.9. Next, subtract 360, leaving 17.9 degrees. Type that 17.9 into the **H** box, replacing the 192.9, and poof, you have its complementary color:
+
+![Change foreground color][5]
+
+If you inspect the text box labeled **HTML notation** you'll see that the color you started with was **#0080a3,** and its complement is **#a33100**. Look at the fields marked **Current** and **Old** to see the two colors complementing each other.
+
+There is a most excellent and detailed [article on Wikipedia explaining HSL (hue, saturation, and lightness) and HSV (hue, saturation, and value) color models][6] and how to convert between them and the RGB standard most of us know.
+
+I'll automate this in Groovy. Because you might want to use this in various ways, create a **Color** class that provides constructors to create an instance of Color and then several methods to query the color of the instance in HSV and RGB.
+
+Here's the **Color** class, with an explanation following:
+
+```

+
+The **Color** class definition, which begins on line 9 and ends on line 146, looks a lot like a Java class definition (at first glance, anyway) that would do the same thing. But this is Groovy, so you have no imports up at the beginning, just comments. Plus, the details illustrate some more Groovyness.
+
+Line 15 creates the private final variable **rgb** that contains the color value supplied to the class constructor. You'll keep this value as **Map** with keys `r`, `g`, and `b` to access the RGB values. Keep the values as double values between 0 and 1 so that 0 would indicate a hexadecimal value of **#00** or an integer value of 0 and 1 would mean a hexadecimal value of **#ff** or an integer value of 255. Use double to avoid accumulating rounding errors when converting inside the class.
+
+Similarly, line 16 creates the private final variable **hsv** that contains the same color value but in HSV format–also a **Map**, but with keys `h`, `s`, and `v` to access the HSV values, which will be kept as double values between 0 and 360 (hue) and 0 and 1 (saturation and value).
+
+Lines 21-28 define a **Color** constructor to be called when passing in an int argument. For example, you might use this as:
+
+```
+def blue = new Color(0x0000ff)
+```
+
+- On lines 22-23, check to make sure the argument passed to the constructor is in the allowable range for a 24-bit integer RGB constructor, and throw an exception if not.
+- On line 25, initialize the **rgb** private variable as the desired RGB Map, using bit shifts and dividing each by a double value 255 to scale the numbers between 0 and 1.
+- On line 26, convert the RGB triplet to HSV and assign it to the **hsv** private variable.
+
+Lines 39-69 define another **Color** constructor to be called when passing in either an RGB or HSV triple as a **Map**. You might use this as:
+
+```
+def green = new Color([r: 0, g: 255, b: 0])
+```
+
+or
+
+```
+def cyan = new Color([h: 180, s: 100, v: 100])
+```
+
+Or similarly with double values scaled between 0 and 1 instead of integers between 0 and 255 in the RGB case and between 0 and 360, 0 and 1, and 0 and 1 for hue, saturation, and value, respectively.
+
+This constructor looks complicated, and in a way, it is. It checks the **keySet()** of the map argument to decide whether it denotes an RGB or HSV tuple. It checks the class of the values passed in to determine whether the values are to be interpreted as integers or double values and, therefore, whether they are scaled into 0-1 (or 0-360 for hue).
+
+Arguments that can't be sorted out using this checking are deemed incorrect, and an exception is thrown.
+
+Worth noting is the handy streamlining provided by Groovy:
+
+```
+def types = triplet.values().collect { it.class }
+```
+
+This uses the **values()** method on the map to get the values as a **List** and then the **collect()** method on that **List** to get the class of each value so that they can later be checked against **[Integer,Integer,Integer]** or **[Double,Double,Double]** to ensure that arguments meet expectations.
+
+Here is another useful streamlining provided by Groovy:
+
+```
+def minV = triplet.min { it.value }.value
+```
+
+The **min()** method is defined on **Map**; it iterates over the **Map** and returns the **MapEntry**—a (key, value) pair—having the minimum value encountered. The **.value** on the end selects the value field from that **MapEntry**, which gives something to check against later to determine whether the values need to be normalized.
+
+Both rely on the Groovy Closure, similar to a Java lambda–a kind of anonymous procedure defined where it is called. For example, **collect()** takes a single **Closure** argument and passes it to each **MapEntry** encountered, known as the parameter within the closure body. Also, the various implementations of the Groovy Collection interface, including here **Map**, define the **collect()** and **min()** methods that iterate over the elements of the **Collection** and call the **Closure** argument. Finally, the syntax of Groovy supports compact and low-ceremony invocations of these various features.
+
+Lines 70-106 define five "getters" that return the color used to create the instance in one of five formats:
+
+- **getHex()** returns an int corresponding to a 24-bit HTML RGB color.
+- **getRgb()** returns a **Map** with keys `r`, `g`, `b` and corresponding double values in the range 0-1.
+- **getRgbI()** returns a **Map** with keys `r`, `g`, `b` and corresponding int values in the range 0-255.
+- **getHsv()** returns a **Map** with keys `h`, `s`, `v` and corresponding double values in the range 0-360, 0-1 and 0-1, respectively.
+- **getHsvI()** returns a **Map** with keys `h`, `s`, `v` and corresponding int values in the range 0-360, 0-100 and 0-100, respectively.
+
+Lines 112-129 define a static private (internal) method **rgb2hsv()** that converts an RGB triplet to an HSV triplet. This follows the algorithm described in the Wikipedia article [section on Hue and chroma][7], except that the algorithm there yields negative hue values when the green value is less than the blue value, so the version is modified slightly. This code isn't particularly Groovy other than using the **max()** and **min()****Map** methods and returning a **Map** instance declaratively without a return statement.
+
+This method is used by the two getter methods to return the **Color** instance value in the correct form. Since it doesn't refer to any instance fields, it is static.
+
+Similarly, lines 134-145 define another private (internal) method **hsv2rgb()**, that converts an HSV triplet to an RGB triplet, following the algorithm described in the Wikipedia article [section on HSV to RGB conversion][8]. The constructor uses this method to convert HSV triple arguments into RGB triples. Since it doesn't refer to any instance fields, it is static.
+
+That's it. Here's an example of how to use this class:
+
+```
+ 1 def favBlue = new Color(0x0080a3)
+
+ 2 def favBlueRgb = favBlue.rgb
+ 3 def favBlueHsv = favBlue.hsv
+
+ 4 println "favBlue hex = ${sprintf('0x%06x',favBlue.hex)}"
+ 5 println "favBlue rgbt = ${favBlue.rgb}"
+ 6 println "favBlue hsvt = ${favBlue.hsv}"
+
+ 7 int spokeCount = 8
+ 8 double dd = 360d / spokeCount
+ 9 double d = favBlue.hsv.h
+ 10 for (int spoke = 0; spoke < spokeCount; spoke++) {
+ 11 def color = new Color(h: d, s: favBlue.hsv.s, v: favBlue.hsv.v)
+ 12 println "spoke $spoke $d° hsv ${color.hsv}"
+ 13 println " hex ${sprintf('0x%06x',color.hex)} hsvI ${color.hsvI} rgbI ${color.rgbI}"
+ 14 d = (d + dd) % 360d
+ 15 }
+```
+
+As my starting value, I've chosen the lighter blue from the [opensource.com][9] header **#0080a3**, and I'm printing a set of seven more colors that give maximum separation from the original blue. I call each position going around the color wheel a spoke and compute its position in degrees in the variable **d**, which is incremented each time through the loop by the number of degrees **dd** between each spoke.
+
+As long as `Color.groovy` and this test script are in the same directory, you can compile and run them as follows:
+
+```
+$ groovy test1Color.groovy
+favBlue hex = 0x0080a3
+favBlue rgbt = [r:0.0, g:0.5019607843137255, b:0.6392156862745098]

+You can see the degree position of the spokes reflected in the HSV triple. I've also printed the hex RGB value and the int version of the RGB and HSV triples.
+
+I could have built this in Java. Had I done so, I probably would have created separate **RgbTriple** and **HsvTriple** helper classes because Java doesn't provide the declarative syntax for **Map**. That would have made finding the min and max values more verbose. So, as usual, the Java would have been more lengthy without improving readability. There would have been three constructors, though, which might be a more straightforward proposition.

+I could have used 0-1 for the hue as I did for saturation and value, but somehow I like 0-360 better.
+

+
+### Wrap up
+
+Color wheels are useful in many situations and building one in Groovy is a great exercise to learn both how the wheel works and the, well, grooviness of Groovy. Take your time; the code above is long. However, you can build your own practical color calculator and learn a lot along the way.
+
+#### Groovy resources
+
+The Apache Groovy language site provides [a good tutorial-level overview][10] of working with Collection, particularly Map classes. This documentation is quite concise and easy to follow, at least partly because the facility it is documenting has been designed to be itself concise and easy to use!

+Use Rexx for scripting in 2023
+======
+
+In a [previous article][1], I showed how the Rexx scripting language is both powerful and easy to use. It uses specific techniques to reconcile these two goals that are often considered in conflict.
+
+This article walks you through two example Rexx scripts so you can get a feel for the language. Rexx purports to be highly capable yet easy to work with.
+
+### An example of a Rexx script
+
+The [LISP programming language][2] is famous for its overuse of parentheses. It can be a real challenge for programmers to ensure they're all matched up correctly.
+
+This short script reads a line of LISP code from the user and determines whether the parentheses in the input are properly matched. If the parentheses aren't properly balanced, the program displays a syntax error.
+
+Below are three sample interactions with the program. In the first, the LISP code I entered was correctly typed. But the next two contain mismatched parentheses that the Rexx script identifies:
+
+```
+Enter a line to analyze:
+(SECOND (LAMBDA (LIS) (FIRST (CDR LIS)) ))
+Parentheses are balanced
+
+Enter a line to analyze:
+((EQSTR (CAR LIS1) (CAR LIS2))
+Syntax error: too many left parens, not balanced
+
+Enter a line to analyze:
+(EQSTR (CAR LIS1) CAR LIS2))
+Syntax error: right paren before or without left paren
+```
+
+Here's the Rexx program:
+
+```
+counter = 0 /* counts parentheses */
+
+say 'Enter a line to analyze:' /* prompts user for input */
+pull input_string /* reads line of user input */
+
+length_of_string = length(input_string)
+
+/* process each character of the input line, one at a time */
+
+do j = 1 to length_of_string while counter >= 0
+
+ character = substr(input_string,j,1)
+ if character = '(' then counter = counter + 1
+ if character = ')' then counter = counter - 1
+
+end
+
+/* display the appropriate message to the user */
+
+if counter = 0 then
+ say 'Parentheses are balanced'
+else if counter < 0 then
+ say 'Syntax error: right paren before or without left paren'
+else
+ say 'Syntax error: too many left parens, not balanced'
+```
+
+First, the program prompts the user to enter a line of input with the `say` instruction. Then it reads it with a `pull` instruction.
+
+`The say` and `pull` instructions are used for conversational input/output, or direct interaction with users. Rexx also supports character-oriented and line- or record- oriented I/O.
+
+Next, the script uses the `length` function to place the length of the input line into the variable `length_of_string`.
+
+The `do` loop processes each character from the input line, one at a time. It increments the `counter` each time it encounters a left parenthesis, and decrements it each time it recognizes a right parenthesis.
+
+If the `counter` ends up as zero after processing the entire input line, the program knows that any parentheses in the input line match up correctly. If the `counter` is not 0 after processing, the input line has mismatched parentheses.
+
+The final `if` statements display the proper message to the user. One could code these `if` statements in any number of styles, as per individual preference. (The main requirement is that whenever multiple statements are coded within a branch, they must be enclosed in a `do...end` group.)
+
+This program shows that Rexx is free-form and case-insensitive. It does not rely on reserved words, so you're free to use common words like `counter` or `character` to represent variables.
+
+The one key requirement Rexx does impose is that any function must immediately be followed by a left parenthesis. Examples in the program are the `length` and `substr` functions. Put a space between a function name and its following parenthesis, and Rexx won't recognize the function.
+
+Outside of a few minimal requirements like these, Rexx requires very little from the programmer in terms of syntax, special characters, or restrictive coding rules.
+
+Rexx programs look and read like pseudo-code. This makes them relatively easy to read and work with.
+
+### A real-world example of a Rexx script
+
+Here's a program from the real world:
+
+Les Koehler, a Rexx user, had a legacy accounting program that matched accounting records on hand against those that a vendor sent to him daily. The legacy program ran for several hours every day to process 25,000 records. It employed a sequential "walk the list" technique to match one set of records against the other.
+
+Les replaced the legacy program with a Rexx script. The Rexx script performs matching by using associative arrays:
+
+```
+/* Create an associative array reflecting */
+/* the values in the first list of names */
+/* by Les Koehler */
+
+flag. = 0 /* Create array, set all items to 0 */
+do a = 1 to list_a.0 /* Process all existing records */
+ aa = strip(list_a.a) /* Strip preceding/trailing blanks */
+ flag.aa = 1 /* Mark each record with a 1 */
+end
+
+/* Try to match names in the second list */
+/* against those in the associative array */
+
+m = 0 /* M counts number of missing names */
+do b = 1 to list_b.0 /* Look for matching name from LIST_B */
+ bb = strip(list_b.b) /* Put LIST_B name into variable BB */
+ if \ flag.bb then do /* If name isn't in FLAG array */
+ m = m+1 /* add 1 to count of missing names */
+ missing.m = bb /* add missing name to MISSING array */
+ end
+end
+
+missing.0 = m /* Save the count of unmatched names */
+```
+
+Les was able to reduce processing time from several hours down to a matter of seconds.
+
+The first line of code (`flag. = 0`) creates a new array called `flag` and initializes every element in that array to `0`.
+
+The array `list_a` contains all the existing accounting records. Its first element (`list_a.0`) by convention contains the number of elements in the array.
+
+So the first `do` loop processes all elements in the array of existing records (`list_a`) and marks each of them as existing in the `flag` array. The statement `flag.aa = 1` marks the content-addressable item in the `flag` array as present.
+
+The second `do` loop peddles through each item in the set of new records, contained in the array called `list_b`.
+
+The `if` statement checks whether an item from the second array of records is marked present in the `flag` array. If not, the program increments the number of items present in the new list of accounting records that do not exist in the old list of records. And it puts the missing item into the `missing` array: `missing.m = bb`.
+
+The final statement (`missing.0 = m`) simply updates the number of items in the `missing` array, by convention stored in array position 0.
+
+### Rexx improvements
+
+Why is this Rexx program so fast compared to the legacy code it replaces? First, the associative arrays allow direct lookup of a new record against the old records. Direct access is much faster than the sequential "walk-the-list" technique it replaced.
+
+Secondly, all the array elements reside in memory. Once the files of the old and new accounting records have been initialized into the Rexx arrays, no further disk I/O is needed. Disk I/O is always orders of magnitude slower than memory access.
+
+A Rexx array expands as much as memory allows. This script takes advantage of modern computers with seemingly endless amounts of RAM, and frees the programmer from managing memory.
+
+### Conclusion
+
+I hope these two simple programs have shown how easy Rexx is to read, write, and maintain. Rexx is designed to put the burden of programming on the machine instead of the programmer. Yet the language still has plenty of power, due to the design techniques I've described in this series of articles.

+
+How I use my old camera as a webcam with Linux
+======
+
+This year after largely abandoning my MacBook in favor of a NixOS machine, I started getting requests to "turn my camera on" when video calling people. This was a problem because I didn't have a webcam. I thought about buying one, but then I realized I had a perfectly good Canon EOS Rebel XS DSLR from 2008 lying around on my shelf. This camera has a mini-USB port, so naturally, I pondered: Did a DSLR, mini-USB port, and a desktop PC mean I could have a webcam?
+
+There's just one problem. My Canon EOS Rebel XS isn't capable of recording video. It can take some nice pictures, but that's about it. So that's the end of that.
+
+Or is it?
+
+There happens to be some amazing open source software called [gphoto2][1]. Once installed, it allows you to control various supported cameras from your computer and it takes photos and videos.
+
+### Supported cameras
+
+First, find out whether yours is supported:
+
+```
+$ gphoto2 --list-cameras
+```
+
+### Capture an image
+
+You can take a picture with it:
+
+```
+$ gphoto2 --capture-image-and-download
+```
+
+The shutter activates, and the image is saved to your current working directory.
+
+### Capture video
+
+I sensed the potential here, so despite the aforementioned lack of video functionality on my camera, I decided to try `gphoto2 --capture-movie`. Somehow, although my camera does not support video natively, gphoto2 still manages to spit out an MJPEG file!
+
+On my camera, I need to put it in "live-view" mode before gphoto2 records video. This consists of setting the camera to portrait mode and then pressing the **Set** button so that the viewfinder is off and the camera screen displays an image. Unfortunately, though, this isn't enough to be able to use it as a webcam. It still needs to get assigned a video device, such as `/dev/video0`.
+
+### Install ffmpeg and v4l2loopback
+
+Not surprisingly, there's an open source solution to this problem. First, use your package manager to install `gphoto2`, `ffmpeg`, and `mpv`. For example, on Fedora, CentOS, Mageia, and similar:
+
+```
+$ sudo dnf install gphoto2 ffmpeg mpv
+```
+
+On Debian, Linux Mint, and similar:
+
+```
+$ sudo apt install gphoto2 ffmpeg mpv
+```
+
+I use NixOS, so here's my configuration:
+
+```
+# configuration.nix
+...
+environment.systemPackages = with pkgs; [
+ ffmpeg
+ gphoto2
+ mpv
+...
+```
+
+Creating a virtual video device requires the `v4l2loopback` Linux kernel module. At the time of this writing, that capability is not included in the mainline kernel, so you must download and compile it yourself:
+
+```
+$ git clone https://github.com/umlaeute/v4l2loopback
+$ cd v4l2loopback
+$ make
+$ sudo make install
+$ sudo depmod -a
+```
+
+If you're using NixOS like me, you can just add the extra module package in `configuration.nix`:
+
+```
+[...]
+boot.extraModulePackages = with config.boot.kernelPackages;
+[ v4l2loopback.out ];
+boot.kernelModules = [
+ "v4l2loopback"
+];
+boot.extraModprobeConfig = ''
+ options v4l2loopback exclusive_caps=1 card_label="Virtual Camera"
+'';
+[...]
+```
+
+On NixOS, run `sudo nixos-rebuild switch` and then reboot.
+
+### Create a video device
+
+Assuming your computer currently has no `/dev/video` device, you can create one on demand thanks to the `v4l2loopback`.
+
+Run this command to send data from `gphoto2` to `ffmpeg`, using a device such as `/dev/video0` device:
+
+```
+$ gphoto2 --stdout --capture-movie |
+ ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -f v4l2 /dev/video0
+```
+
+You get output like this:
+
+```

+
+```
+$ mpv av://v4l2:/dev/video0 --profile=low-latency --untimed
+```
+
+![Streaming a live feed from the webcam][2]
+
+### Start your webcam automatically
+
+It's a bit annoying to execute a command every time you want to use your webcam. Luckily, you can run this command automatically at startup. I implement it as a `systemd` service:
+
+```
+# configuration.nix
+...
+ systemd.services.webcam = {
+ enable = true;
+ script = ''
+ ${pkgs.gphoto2}/bin/gphoto2 --stdout --capture-movie |
+ ${pkgs.ffmpeg}/bin/ffmpeg -i - \
+ -vcodec rawvideo -pix_fmt yuv420p -f v4l2 /dev/video0
+ '';
+wantedBy = [ "multi-user.target" ];
+ };
+...
+```
+
+On NixOS, run `sudo nixos-rebuild switch` and then reboot your computer. Your webcam is on and active.
+
+To check for any problems, you can use `systemctl status webcam`. This tells you the last time the service was run and provides a log of its previous output. It's useful for debugging.
+
+### Iterating to make it better
+
+It's tempting to stop here. However, considering the current global crises, it may be pertinent to wonder whether it's necessary to have a webcam on all the time. It strikes me as sub-optimal for two reasons:
+
+- It's a waste of electricity.
+- There are privacy concerns associated with this kind of thing.
+
+My camera has a lens cap, so to be honest, the second point doesn't really bother me. I can always put the lens cap on when I'm not using the webcam. However, leaving a big power-hungry DSLR camera on all day (not to mention the CPU overhead required for decoding the video) isn't doing anything for my electricity bill.
+
+The ideal scenario:
+
+- I leave my camera plugged in to my computer all the time but switched off.
+- When I want to use the webcam, I switch on the camera with its power button.
+- My computer detects the camera and starts the systemd service.
+- After finishing with the webcam, I switch it off again.
+
+To achieve this, you need to use a custom [udev rule][3].
+
+A udev rule tells your computer to perform a certain task when it discovers that a device has become available. This could be an external hard drive or even a non-USB device. In this case, you need it to [recognize the camera through its USB connection][4].
+
+First, specify what command to run when the udev rule is triggered. You can do that as a shell script (`systemctl restart webcam` should work). I run NixOS, so I just create a derivation (a Nix package) that restarts the systemd service:
+
+```
+# start-webcam.nix
+with import { };
+writeShellScriptBin "start-webcam" ''
+ systemctl restart webcam
+ # debugging example
+ # echo "hello" &> /home/tom/myfile.txt
+ # If myfile.txt gets created then we know the udev rule has triggered properly''
+```
+
+Next, actually define the udev rule. Find the device and vendor ID of the camera. Do this by using the `lsusb` command. That command is likely already installed on your distribution, but I don't use it often, so I just install it as needed using `nix-shell`:
+
+```
+$ nix-shell -p usbutils
+```
+
+Whether you already have it on your computer or you've just installed it, run `lsusb`:
+
+```
+$ lsusb
+Bus 002 Device 008: ID 04a9:317b Canon, Inc. Canon Digital Camera[...]
+```
+
+In this output, the vendor ID is 04a9 and the device ID is 317b. That's enough to create the udev rule:
+
+```
+ACTION=="add", SUBSYSTEM=="usb",
+ATTR{idVendor}=="04a9",
+ATTR{idProduct}=="317b",
+RUN+="/usr/local/bin/start-webcam.sh"
+```
+
+Alternatively, if you're using NixOS:
+
+```
+# configuration.nix[...]let
+ startWebcam = import ./start-webcam.nix;[...]
+services.udev.extraRules = ''
+ ACTION=="add", \
+ SUBSYSTEM=="usb", \
+ ATTR{idVendor}=="04a9", \
+ ATTR{idProduct}=="317b", \
+ RUN+="${startWebcam}/bin/start-webcam"'';[...]
+```
+
+Finally, remove the **wantedBy = ["multi-user.target"];** line in your `start-webcam` systemd service. (If you leave it, then the service starts automatically when you next reboot, whether the camera is switched on or not.)
+
+### Reuse old technology
+
+I hope this article has made you think twice before chucking some of your old tech. Linux can breathe life back into technology, whether it's your [computer][5] or something simple like a digital camera or some other peripheral.

+Discover the power of the Linux SpaceFM file manager
+======
+
+SpaceFM is a tabbed file manager for Linux using the GTK toolkit, so it fits right in on desktops like [GNOME][1], [Mate][2], [Cinnamon][3], and others. SpaceFM also features a built-in device manager system, so it's particularly good for window managers, like [Fluxbox][4] or [fvwm][5], which typically don't include a graphical device manager. If you're happy with the file managers on Linux, but you want to try one that's a little bit different in design, SpaceFM is worth a look.
+
+### Install SpaceFM
+
+On Linux, you're likely to find **SpaceFM** in your distribution's software repository. On Fedora, Mageia, OpenMandriva, and similar:
+
+```
+$ sudo dnf install spacefm
+```
+
+On Debian and Debian-based systems:
+
+```
+$ sudo apt install spacefm
+```
+
+### Panels
+
+I don't know why SpaceFM is called SpaceFM, but it could be because it makes a concerted effort to let you use every bit of space in its window for something useful. By default, SpaceFM is actually pretty simple, standard-issue file manager. It has a single panel listing your files, a toolbar, and a menu bar.
+
+![SpaceFM is typical in design. At first.][6]
+
+All the "usual" rules apply.
+
+- **Double-click** to open a directory or to open a file in its default application.
+- **Right-click** for a contextual menu providing lots of standard options (copy, paste, rename, view properties, create a new folder, and so on).
+
+The way SpaceFM sets itself apart, though, is its panel system. SpaceFM displays one panel by default. That's the big file window listing your files. But it can have up to four panel views, plus a few bonus panels for some specific tasks.
+
+### Opening a new panel
+
+Instead of seeing one directory in your file manager, you can see two. To bring up another directory in its own pane, press **Ctrl+2** or go to the **View** menu and select **Panel 2**. Alternatively, click the second green dot icon from the left in the menu panel.
+
+With two panels, you can move files from one directory to another without opening a new file manager window, or you can browse two directories to compare their contents.
+
+But why settle for two panels? Maybe you'd rather see _three_ directories at once. To bring up a third directory in a dedicated pane, press **Ctrl+3** or go to the **View** menu and select **Panel 3**. Alternatively, click the third green dot icon from the left in the menu panel. This panel appears at the bottom of the SpaceFM window.
+
+With three panels open, you can move files between several directories, or sort files from a common "dumping ground" (like your Desktop or Downloads folder) into specific directories.
+
+Of course, once you've tried three panels you'll probably find yourself itching for a fourth. To open a fourth directory in its own pane, press **Ctrl+4** or go to the **View** menu and select **Panel 4**. Alternatively, click the fourth green dot icon from the left in the menu panel. This one opens next to Panel 3, splitting your SpaceFM window into even quarters.
+
+![SpaceFM can have up to four panels.][7]
+
+What about a _fifth_ panel? Well, actually SpaceFM stops at four panels. If you really do want a fifth panel, you have to open a new SpaceFM window. However, there are still more panels, used for information other than file listings, to explore.
+
+### Special panels
+
+The **View** menu reveals that in addition to file panels, there are additionally task-specific panels you can choose to display. This includes:
+
+- **Task manager**: Lists ongoing file manager processes. This isn't a general-purpose task manager, so to set nice values or detect a zombie apocalypse of undead PIDs, [htop or top][8] is still your utility of choice.
+- **Bookmarks**: Links to common folders, such as Desktop, Documents, Downloads, and any location you want to keep handy.
+- **Devices**: USB thumb drives and remote file systems.
+- **File tree**: A view of your file system in order of directory inheritance.
+
+These panels open on the left side of SpaceFM, but they do stack. You can have bookmarks, devices, tasks, and a file tree open at once, although it helps to have a very tall SpaceFM window.
+
+### Make space for SpaceFM
+
+SpaceFM is a configurable multi-tasking file manager. It maximizes the information you can build into a single window, and it lets you decide what's important, and when. This article has focused on the panels of SpaceFM because those are, at least in my view, the most unique aspect of the application. However, there's a lot more to SpaceFM, including plugins, preferences, a design mode, keyboard shortcuts, and customization. This isn't a small application, even though it is a lightweight one. Spend some time with SpaceFM, because you never know what you'll discover.

+Fedora Media Writer: World-Class LIVE USB Creator [Tutorial]
+======
+
+**A tutorial on installing and using Fedora Media Writer to create LIVE USB from Linux & Windows.**
+
+![Fedora Media Writer][1]
+
+### Fedora Media Writer
+
+The community and Fedora Linux team develop and maintain the [Fedora Media Writer app][2]. This application writes any ISO image to your flash drive (USB stick). In addition, Fedora Media Writer also has features to download the ISO file directly from the Fedora Mirrors, provided you have a stable internet connection.
+
+Moreover, it gives you a list of options for download – such as Official Editions, Emerging Editions, Spins and Fedora Labs images.
+
+Not only that, but you can also use this nifty utility to write any other ISO images to your flash drive. It need not be the Fedora ISO always.
+
+Although there are other popular utilities available for creating LIVE USBs, such as [Etcher][3], Ventoy, and Rufus – you can still give this utility a try, considering the team develops it from mainstream Fedora Linux with contributors.
+
+So, in summary, here are quick feature highlights of Fedora Media Writer.
+
+#### Features Summary of Fedora Media Writer
+
+- Available for Linux, Windows and macOS
+- Directly download + write the images to a USB flash drive
+- Official Editions (Workstation, IoT, Server) download
+- Emerging Editions (Silverblue, Kinoite) download
+- Spins (KDE Plasma, Xfce, etc)
+- Labs (Fedora Astronomy, Robotic and other flavours)
+- Available as Flatpak for Linux Distros
+- Also, can write any other ISO images (non-Fedora) to a USB stick.
+- Ability to format USB stick, restore flash drive
+- Based on Qt
+
+### How to Install
+
+#### Linux
+
+Fedora Media Writer is available as Flatpak for Linux Distributions. To install it in any Linux (such as Fedora, Ubuntu, or Linux Mint) – [set up Flatpak by following this guide][4].
+
+Then, click on the below link to install. This will launch the official Software application of your Linux Distro (such as Discover, GNOME Software). After installation, you can launch it via Application Menu.
+
+[Install Fedora Media Writer as Flatpak][5]
+
+#### Windows
+
+If you are a Windows user and planning to migrate to Linux (or Fedora), it is a perfect tool. You need to download the exe installer from GitHub (link below) and follow the onscreen instruction for installation.
+
+[Latest Installer for Windows (exe)][6]
+
+After installation, you can launch it from Start Menu.
+
+For macOS, you can get the dmg file in the above link.
+
+### How to use Fedora Media Writer to Create LIVE USB in Linux
+
+The first screen gives you two main options. The automatic download option is for downloading the ISO images on the fly. And the second option is to write the already downloaded ISO files from your disk directly.
+
+If you have already plugged in the USB, you should see it as the third option. The third option is to format and delete all the data from your USB stick and restore it to its factory settings.
+
+Furthermore, you can use this utility for just formatting your USB flash drive as well. You do not need any command or anything fancy. A point to note is that this option is only visible when your USB stick has data. If it’s already formatted, the tool can detect it and won’t show you the option to restore it!! 😲
+
+#### Automatic Download and Write
+
+![Fedora Media Writer - First Screen][7]
+
+The automatic Download option gives you the following screen to download any Fedora ISO you want from mirrors. This is useful for many because it eliminates the hassles of separately downloading ISO files, verifying checksum, etc.
+
+![The automatic download options gives you these options][8]
+
+After choosing the distribution, the final screen gives you the option for version (Fedora 36, 35, etc.) and architecture (x86, ARM, etc.). Also, you should see the USB destination. Click on Download and Write to start the process.
+
+![The final Write screen of Fedora Media Writer][9]
+
+#### Write an existing ISO file from the disk.
+
+When you choose the ‘select iso file’ option, you can select the file from your system. After that, select the destination USB drive and click Write to start the process.
+
+![Direct ISO write via Fedora Media Writer][10]
+
+![Writing is in progress][11]
+
+![Writing Complete][12]
+
+After the write operation is finished, you can see a confirmation message shown above. It took standard time to write a 3GB~ ISO during my test, around 3 to 4 minutes.
+
+### Using Fedora Media Writer to Create LIVE USB in Windows, macOS
+
+The steps are the same to use this utility in Windows and macOS, as shown above for Linux. You can easily find the shortcuts after installation and launch in the same way.
+
+![Running in Windows 11][13]
+
+### Closing Notes
+
+I hope this guide helps you use Fedora Media Writer for your day to day USB writing work. Also, the good thing about this utility is that you can use it for formatting/restoring your USB stick. You do not require GParted or GNOME Disks anymore.
+
+It’s such a terrific utility for Linux, Windows and macOS users.
+
+Cheers.

+
+Writing a Macro in LibreOffice Calc: Getting Started
+======
+
+**Planning to automate stuff in LibreOffice? Start writing your first LibreOffice Calc macro using this guide.**
+
+LibreOffice provides a way to write your macro to automate various repetitive tasks in your office application. You can use Python or basic for your macro development. This tutorial focuses on writing a macro in LibreOffice with a ‘Hello World’ macro in the Basic programming language.
+
+### Write your first macro in LibreOffice Calc
+
+### Macro Objective
+
+We are going to create a macro that would put the string ‘Hello World’ in the first cell of LibreOffice calc, i.e. the cell of row 1 and col A.
+
+### Creating the Macro
+
+- Open LibreOffice Calc from `Applications => Office => LibreOffice Calc`.
+
+![LibreOffice_1][1]
+
+- Go to the option from the menu: `Tools ==> Macros ==> Organize Macros ==> LibreOffice Basic`. Below ‘LibreOffice basic macros’ window will open.
+
+![LibreOffice_2][2]
+
+- Give your desired name in the macro name box and click New. You can use any name you want. For this tutorial, I have used hello_world.
+
+![LibreOffice_3][3]
+
+- Once you have clicked the New button, the macro editor will open. Here are some things to note in this window. This is the place where you should be writing your code, debugging your code, etc. You can see the macro’s name became the function name of your basic macro.
+
+![LibreOffice_4][4]
+
+- Now, it’s time to code the first macro. Let’s declare two variables of type objects.
+
+```
+dim document as object dim dispatcher as object
+```
+
+- Let’s assign two values to the above variables.
+
+```
+document = ThisComponent.CurrentController.Frame dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")
+```
+
+`ThisComponent` refers to the current document.
+
+In LibreOffice, everything you do, e.g. type, colour, insert, is “watched” by a controller. The controller then dispatches the changes to the document frame, i.e. the main window area of the Calc. So the document variable refers to the main area of Calc.
+
+The `createUnoService` creates an instance of the `DispatchHelper` service. This service will help us to dispatch the tasks from the macro to the frame. Almost all LibreOffice macro tasks can be executed using the dispatcher.
+
+- Now we will declare an array of properties. Properties are always in a name/value pair. Thus the name contains the property name, and the value contains the value of that property.
+
+```
+dim args1(0) as new com.sun.star.beans.PropertyValue
+```
+
+Our objective is to put ‘Hello World’ in the first Cell. To point to the first cell A1 and put a text, we would use two properties – `ToPoint` and `StringName`.
+
+Once we set the properties, it’s time to call the dispatch to send these to the document. So call the `executeDispatch` event of the dispatcher using two commands: `.uno:GoToCell`, and `.uno:EnterString`.
+
+```
+dim args2(0) as new com.sun.star.beans.PropertyValueargs1(0).Name = "ToPoint" args1(0).Value = "$A$1" args2(0).Name = "StringName" args2(0).Value = "Hello World!"
+```
+
+These commands tell the frame what needs to be executed and also pass the entire property array with values.
+
+![LibreOffice_5][5]
+
+Now put a message box to notify when the execution is completed.
+
+### Running the Macro
+
+- It’s time to run the macro. To run the macro, press `F5` or click Run Macro from the toolbar (see above).
+- After execution, the message box would pop up. If you go back and check the Calc spreadsheet, you should see ‘Hello World!’ written in the first Cell.
+
+![LibreOffice_6][6]
+
+![LibreOffice_7][7]
+
+### Complete Code
+
+```
+REM ***** BASIC *****
+sub hello_world
+
+ dim document as object
+ dim dispatcher as object
+
+ document = ThisComponent.CurrentController.Frame
+ dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")
+
+ dim args1(0) as new com.sun.star.beans.PropertyValue
+ dim args2(0) as new com.sun.star.beans.PropertyValue
+
+ args1(0).Name = "ToPoint"
+ args1(0).Value = "$A$1"
+ dispatcher.executeDispatch(document, ".uno:GoToCell", "", 0, args1())
+
+ args2(0).Name = "StringName"
+ args2(0).Value = "Hello World!"
+ dispatcher.executeDispatch(document, ".uno:EnterString", "", 0, args2())
+
+ msgbox "Completed!"
+end sub
+```

+
+How I use Artipie, a PyPI repo
+======
+
+While developing with Python as a student, I found that I needed some private centralized storage. This was so I could store binary and text data files, as well as Python packages. I found the answer in [Artipie][1], an open source self-hosted software repository manager.
+
+At university, my colleagues and I conducted research and worked with a lot of data from experimental measurements. I used Python to process and visualize them. My university colleagues at the time were mathematicians and didn't have experience with software development techniques. They usually just passed data and code on a flash drive or over email. My efforts to introduce them to a versioning system like [Git][2] were unsuccessful.
+
+### Python repository
+
+Artipie supports the [PyPI][3] repository, making it compatible with both [twine][4] and [pip][5]. This means you can work with the Artipie Python repository exactly as you would when installing or publishing packages on the [PyPI][3] and [TestPyPI][6] repositories.
+
+To create your own Python repository, you can use the hosted instance of Artipie called [Artipie Central][7]. Once you sign in, you see a page with your repositories listed (which is empty to begin with) and a form to add a new repository. Choose a name for your new repository (for example, `mypython`), select "Python" as the repository type, and then click the **Add** button.
+
+Next, you see a page with repository settings in the [YAML][8] format:
+
+```
+---
+repo:
+ type: pypi
+ storage: default
+ permissions:
+ olenagerasimova:
+ - upload
+ "*":
+ - download
+```
+
+The `type` mapping in the configuration sets the repository type. In this example, the Python repository is configured with the default Artipie Central storage.
+
+The `storage` mapping defines where all of the repository packages are stored. This can be any file system or S3 storage compatible location. Artipie Central has a preconfigured `default` storage that can be used for tests by anyone.
+
+The `permissions` mapping allows uploads for the user `olenagerasimova`, and allows anyone to download any package.
+
+To make sure this repository exists and works, open the [index page][9] in your browser. The packages list is displayed. If you've just created a new repository but have yet to upload a package, then the repository index page is blank.
+
+### Binary repository
+
+You can store any kind of file in Artipie. The storage type is called file or binary, and I use this as storage for experimental data. I use this as input for Python visualizations. A file repository can be created in Artipie Central the same way as a Python repository. You give it a name, choose the type **binary**, and then click the **Add** button.
+
+```
+---
+repo:
+ type: file
+ storage: default
+ permissions:
+ olenagerasimova:
+ - upload
+ - download
+ "*":
+ - download
+```
+
+The settings are basically the same as for Python. Only the repository type differs. The binary repository, in this example, is called `data`. It contains three text files with some numbers:
+
+```
+6
+3.5
+5
+4
+4.5
+3
+2.7
+5
+6
+3
+1.2
+3.2
+6
+```
+
+The other two files take the same form (only the numbers are different.) To see the files yourself, open the links [one][10], [two][11], and [three][12] in your browser and download the files, or you can perform a GET request using `httpie`:
+
+```
+httpie -a https://central.artipie.com/olenagerasimova/data/y1.dat > ./data/y1.da
+```
+
+These files were uploaded to the Artipie Central `data` repository with PUT requests:
+
+```
+httpie -a olenagerasimova:*** PUT
+https://central.artipie.com/olenagerasimova/data/y1.dat @data/y1.dat
+
+httpie -a olenagerasimova:*** PUT
+https://central.artipie.com/olenagerasimova/data/y2.dat @data/y2.dat
+
+httpie -a olenagerasimova:*** PUT
+https://central.artipie.com/olenagerasimova/data/y3.dat @data/y3.dat
+```
+
+As this binary repository API is very simple (HTTP `PUT` and `GET`requests), it's easy to write a piece of code in any language to upload and download the required files.
+
+### Python project
+
+The source code of an example Python project is available from my [GitHub repository][13]. The main idea of the example is to download three data files from Artipie Central, read the numbers into arrays, and use these arrays to draw a plot. Use pip to install the example package and run it:
+
+```
+$ python3 -m pip install --index-url \
+https://central.artipie.com/olenagerasimova/pypi/ \
+pypiexample
+$ python3 -m pypiexample
+```
+
+By setting the `--index-url` to the Artipie Central Python repository, pip downloads the packages from it rather than the PyPi repository that serves as the usual default. After running the commands, a polar plot with three curves, a visualization of the data files is displayed.
+
+To publish the package to the Artipie Central repository, build it with and use twine to upload it:
+
+```
+commandline
+$ python setup.py sdist bdist_wheel
+
+$ twine upload --repository-url \
+https://central.artipie.com/olenagerasimova/pypi
+-u olenagerasimova -p *** dist/*
+```
+
+That's how easy it is to set up a `files` repositories in Artipie Central, create a sample Python project, publish, and install it. You don't have to use Artipie Central, though. Artipie can be self-hosted, so you can run a repository on your own local network.
+
+### Run Artipie as a container
+
+Running Artipie as a container makes setup as easy as installing either Podman or Docker. Assuming you have one of these installed, open a terminal:
+
+```
+$ podman run -it -p 8080:8080 -p 8086:8086 artipie/artipie:latest
+
+```
+
+This starts a new container running the latest Artipie version. It also maps two ports. Your repositories are served on port 8080. The Artipie Rest API and Swagger documentation are provided on port 8086. A new image generates a default configuration, printing a list of running repositories, test credentials, and a link to the [Swagger][14] documentation to your console.
+
+You can also use the Artipie Rest API to see existing repositories:
+
+- Go to the Swagger documentation page at `http://localhost:8086/api/index-org.html`**.**
+- In the **Select a definition** list, choose **Auth token**
+- Generate and copy the authentication token for the user artipie with the password artipie
+- Switch to the **Repositories** definition and click the **Authorize** button, and then paste in the token
+
+![Image of the Swagger documentation page,][15]
+
+Perform a GET request for `/api/v1/repository/list`. In response, you receive a JSON list with three default repositories:
+
+```
+[
+ "artipie/my-bin",
+ "artipie/my-docker",
+ "artipie/my-maven"
+]
+```
+
+The Python repository isn't included in the default configuration. You can correct that by performing a PUT request to `/api/v1/repository/{user}/{repo}` from the Swagger interface. In this case, `user` is the name of the default user (`artipie`) and `repo` is the name of the new repository. You can call your new Python repository `my-pypi`. Here's an example request body, containing a JSON object with the repository settings:
+
+```
+{
+ "repo": {
+ "type": "pypi",
+ "storage": "default",
+ "permissions": {
+ "*": [
+ "download"
+ ],
+ "artipie": [
+ "upload"
+ ]
+ }
+ }
+}
+```
+
+All the JSON fields are the same as when you create a repository in the dashboard in YAML format. The type of our repository is `pypi`, the default storage is used, and anyone can download but only the user `artipie` can upload.
+
+Make a GET request to `/api/v1/repository/list` again to make sure your repository was created. Now, you have four repositories:
+
+```
+[
+ "artipie/my-bin",
+ "artipie/my-docker",
+ "artipie/my-maven",
+ "artipie/my-pypi"
+]
+```
+
+You've created your own Artipie installation, containing several repositories! The Artipie image can run both on a personal computer or on a remote server inside a private network. You can use it to exchange packages within a company, group, or university. It's an easy way to set up your own software services, and it's not just for Python. Take some time to explore Artipie and see what it can make possible for you.

+
+Explore the features of the Linux Double Commander file manager
+======
+
+Double Commander is a graphical dual-pane file manager for Linux, in the tradition of [Midnight Commander][1] (`mc`). While Midnight Commander (like the DOS application **Norton Commander** before it) has its fans, its audience is limited by the fact that it only runs in a terminal window. Not everyone wants to use a "flat" interface embedded in a terminal to browse their file system, and so Double Commander provides a similar interface in a way that feels familiar to many desktop users.
+
+![Image of Double Commander's 2 panel view.][2]
+
+### Install Double Commander
+
+To install Double Commander, visit its [website][3] and download [a package][4]. It's not packaged for a specific Linux distribution, so just download an archive for your CPU architecture.
+
+If you only want to try it out, you can unarchive it and then launch it from your Downloads folder.
+
+To install it permanently, unarchive the package, move it into a location [in your path][5], and then symlink `doublecmd` to the executable in the source directory:
+
+```
+$ tar xvf doublecmd*tar.xz
+$ mv doublecmd ~/.local/bin/doublecmd-X.Y.Z
+$ ln -s ~/.local/bin/doublecmd-X.Y.Z/doublecmd ~~/.local/bin/doublecmd
+```
+
+### How to start Double Commander
+
+To start Double Commander, use the command `doublecmd`.
+
+Alternatively, you can add an entry for Double Commander in your application menu. First, create the file `~/.local/share/applications/doublecmd.desktop` and enter this text into it:
+
+```
+[Desktop Entry]Encoding=UTF-8Name=doublecmdGenericName=Double CommanderComment=doublecmdExec=../bin/doublecmdIcon=/usr/share/icons//Adwaita/scalable/apps/system-file-manager-symbolic.svgTerminal=falseType=ApplicationCategories=System;FileTools;Utility;Core;GTK;FileManager;
+```
+
+Now Double Commander appears in your desktop application menu. Note that this does not make Double Commander your default file manager. It only adds it as an application you can launch when you want to.
+
+### Two panels
+
+Dual-panel file management is a tradition within a subset of file managers, and to some users it's a little unsettling. If you think about it, though, most file management tasks involve a _source_ location and a _destination_ location. You might be used to a workflow that goes something like this:
+
+- Open a file manager and find a file you want to move.
+- Open another file manager window and navigate to the folder you want to move the file into.
+- Drag and drop the file from one window to the other.
+
+You might use a variation of this involving, for instance, a right-click to copy combined with some navigation and another right-click to paste. Either way, the ingredients are the same. You locate the source, you locate the destination, and then you make the transfer.
+
+Given that common factor, it makes sense that a file manager like Double Command has a persistent view of the source location and the destination location. At the very least, it saves you from having to open another window.
+
+### Double Commander interface
+
+Once you get used to the idea of two concurrent views in your file system, there are a lot more features to discover in Double Commander.
+
+- **Menu bar**: At the top of the window is a menu bar. That's pretty standard conceptually, but the menu entries are probably unlike any menu bar you've seen before: **File**, **Mark**, **Commands**, **Network**, **Tabs**, and more. These are task-specific menus, which is great because you can ignore an entire submenu you don't use.
+- **Toolbar**: Under the menu bar, there are buttons for common tasks such as opening a terminal, copying a file, synchronizing two directories, and more.
+- **Locations**: The location bar is situated just under the toolbar. It lists devices and file system locations, including your boot partition, optical media drive, virtual shared locations, the root directory, your home directory (listed as `~`), and more.
+- **File list**: Most of the Double Commander window is occupied by the dual panel view of your file system.
+- **Command**: My favorite feature of Double Commander is the single command field below the file list pane. This allows you to enter an arbitrary command to run within the active pane. This is great for the odd command you need to run in a directory that _no_ file manager expects you to run, and so no file manager has a function for. It's the brute force method of the plugin model: Provide a command line and let users run what they need to run whenever they need to run it.
+- **Functions**: Along the very bottom of the Double Commander window, as with Midnight Commander, there's a list of common functions, each assigned to a Function key on your keyboard.
+
+### Using Double Commander
+
+Using Double Commander is a lot like using any file manager, except that Double Commander is focused on groups of actions. For instance, the **File** menu isn't an obligatory entry with just **New Window** and **New Tab**, it's full of useful functions, like creating a symlink or hard link, changing attributes, comparing contents, bulk renaming, splitting and combining files, and more. Double Commander is direct. It gets straight to the point, serving as a stand-in for all the commands you'd normally run in a terminal.
+
+### Graphical command interface
+
+More than any other file manager I've seen, Double Commander feels like it's meant to be a graphical interface for commands. You can map almost everything in its interface to a command or series of commands you're used to running in a terminal.
+
+Of course, the question then is whether you need a graphical command line. Why not just run the commands in a terminal? Interestingly, I had the opportunity to witness the value of this recently. There are times, as a support person for other computer users, when trying to get a user to navigate the terminal can be overwhelming. This is particularly true when your user is texting on an app on their mobile phone, and you're giving them commands to type into a terminal on their desktop. This introduces several opportunities for mistakes, and what was meant to be "the fast way" of doing something ends up taking an hour.
+
+It's counter-intuitive to a terminal user, and it's not even always true, but there are times when a graphical interface really is easier to give instructions for. Picture it: A zombie apocalypse rages outside your compound, and the file permissions of a vital file need to be changed in order to activate the firewall. "Open a terminal and type chmod a+x /usr/local/bin/foo…no, that's `ch` as in _change_, `mod` as in _mode_ but without the _e_…no, and then a space. Not between the `ch` and the `mod`, just after the `mod`. And then a space. It's `chmod` and _then_ a space. Not the word _space_, just press the spacebar. It's the really long key under your thumb…"
+
+Or you could just say this: "Click on the file, now with that selected, go to the File menu up at the top and click on Change Attributes…"
+
+Double Command's central feature is in its powerful features disguised as a non-threatening graphical file manager. Download and try it out for yourself.

+How to Update Pi-hole Easily
+======
+
+Pi-hole is one of the most effective ad-blockers available for you to use. You can install it on your router or a dedicated system and get an ad-free experience for all the devices connected through it.
+
+In an earlier article, I discussed the [steps for installing Pi-hole][1]. But you must update it regularly to win the cat-and-mouse game between ad blockers and ad providers (Google, Facebook, etc). Another aspect is to patch a security vulnerability that might affect you negatively.
+
+The update method depends on the installation method. To recall, I discussed two methods:
+
+- **Method 1**: The existing Pi-hole installation was conducted using a script. The script was `curl -sSL https://install.pi-hole.net | bash` (or something similar).
+- **Method 2**: You installed Pi-hole using either Podman or Docker as a container.
+
+I will cover how to update Pi-hole with both of these methods.
+
+### Method 1: Updating Pi-hole that was installed by a script
+
+You will not believe how easy this is. All you have to do is run the following command in your terminal!
+
+```
+pihole -up
+```
+
+Of course, you have to run this command on the device where you have installed Pi-hole. In other words, you may have to [SSH into your Raspberry Pi][2] or router to run the above-mentioned command.
+
+Doing so will update Pi-hole. Below is the output of running the `pihole -up` command on my computer:
+
+```
+$ pihole -up
+ [✓] Update local cache of available packages
+ [i] Existing PHP installation detected : PHP version 8.1.2-1ubuntu2.8
+ [✓] Checking for git
+ [✓] Checking for iproute2
+ [✓] Checking for dialog
+ [✓] Checking for ca-certificates
+
+ [i] Checking for updates...
+ [i] Pi-hole Core: up to date
+ [i] Web Interface: up to date
+ [i] FTL: up to date
+
+ [✓] Everything is up to date!
+```
+
+💡Though I haven’t encountered this myself, it is still a possibility that Pi-hole might require updates for _other_ packages (like PHP) be installed. So try and run the update command that is applicable for your package manager on a regular basis. Keeping other packages up-to-date is _just as important_ ;)
+
+#### Optional: Automate Pi-hole update with cron job
+
+This says that everything is up to date. But how can a normal person remember to keep everything up to date? Fret not! We can create a cron job to automatically update Pi-hole every day.
+
+But before we edit the cron job, let us find the absolute path of the `pihole` command. This can be done either using the `which` command or the `command` command. You only need to run either one of the two commands listed below:
+
+```
+command -v pihole
+which pihole
+```
+
+Executing either of the commands listed above will give you the absolute path to the `pihole` command. In my case, the absolute path for the `pihole` command is `/usr/local/bin/pihole`.
+
+Next, we will edit the [cron job][3]. To edit cron jobs, type the following command in your terminal (please do **NOT** use `sudo`):
+
+```
+crontab -e
+```
+
+Doing so will open a file in either the `nano` editor or the `vim` editor. Next, _append_ the following lines to the currently opened file:
+
+```
+0 1 * * * /usr/local/bin/pihole -up
+```
+
+All you need to do now is to save and exit the editor.
+
+What we just did was that we made updating Pi-hole an automatic task. This will automatically run the `pihole up` command at 01:00 hours, every day.
+
+### Method 2: Update Pi-hole that was installed via Podman or Docker
+
+If you installed Pi-hole using either Podman or Docker, all you can do initially is to pull the image.
+
+⚠️ If you used a `docker-compose.yml` file to create your container, please have it handy because we need to delete the current container and create a new one. (No data or configuration will be changed if volumes are backed up properly or if bind mounts were used.)
+
+#### Step 1: Check if a newer image is available
+
+To check for updates, you can run either of the following commands based on what you use:
+
+```
+# command for Podman users
+podman pull docker.io/pihole/pihole:latest
+
+# command for Docker users
+docker pull docker.io/pihole/pihole:latest
+```
+
+If there is a newer version of the image, it will be fetched. If a newer version is not available, nothing extra will happen and you should try again later.
+
+#### Step 2: Stop and remove the container
+
+If a new image was downloaded, we can proceed further. Our next step should be to restart the container. To know which container to restart, we can check the output of the `docker ps` or `podman ps` command.
+
+```
+$ docker ps
+CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
+73528d5ca4e8 docker.io/pihole/pihole:latest 14 hours ago Up 14 hours ago 53/tcp pihole-aditi
+```
+
+This shows that I have a container named `pihole-aditi`. Let’s stop and remove this container. This can be done with the following commands:
+
+```
+# command for Podman users
+podman stop pihole-aditi
+docker rm pihole-aditi
+
+# command for Docker users
+docker stop pihole-aditi
+docker rm pihole-aditi
+```
+
+#### Step 4: Create a new container
+
+I hope you took my warning seriously and have your `docker-compose.yml` file handy ;)
+
+Let’s re-create a new container. You can re-create your container using the following command:
+
+```
+docker-compose up -d
+```
+
+Please verify that the Pi-hole container is up and running using either the `podman ps` command or the `docker ps` command.
+
+#### Step 5: Remove old image(s)
+
+Once the Pi-hole container starts up with the updated image, we can remove the old image and free up disk, space.
+
+To remove **all the _unused_ images**, use the following command:
+
+```
+# command for Podman users
+podman image prune
+
+# command for Docker users
+docker image prune
+```
+
+Upon running the above command, **all the _unused_** **images** will be removed. **Please take caution with this command.**
+
+Done! That was all that we needed to do to update our Pi-hole container.
+
+### Conclusion
+
+This article goes over the two methods of updating Pi-hole based on the installation method initially used. I have also discussed setting up auto-updates for Pi-hole which was installed using the official script. There is no such option for the container method, unfortunately.
+
+Do let me know if you face any issues.

+EndeavourOS: Your Search for Perfect Arch Distro Ends Here
+======
+
+**We review the recent release of EndeavourOS “Cassini” and the distro overall.**
+
+Hundreds of Linux distributions pop up every year by individuals and small teams. They are mostly the direct derivatives of Debian, Ubuntu, Fedora or Arch Linux – with a few customizations. And no wonder majority of them die every year due to a lack of contributions, vision and persistence.
+
+Three years back, a small team of contributors started EndeavourOS to continue the discontinued Antergos project. And since then, it has become popular because of its simplicity of installation, user experience and features.
+
+![EndeavourOS with Xfce desktop][1]
+
+### EndeavourOS Review
+
+A lot went into developing the distribution, which is quite evident if you have ever tried it out. The motto of this distro is to be a “general purpose” Arch Linux distribution for the masses, discarding the Arch Linux installation fear for new users and the superiority of using Arch.
+
+If you ever tried EndeavourOS, you must have “felt” how “easy” things are to perform on a desktop for the end user, being an Arch distro.
+
+#### Installation and desktop options to choose from
+
+The installation is made super easy with the “one and only” Calamares installer. On top of that EndeavourOS team gave extra caution to provide you with most of the options during the installation steps. For example, the LIVE medium boots up directly without user intervention. And it launches the welcome screen. The welcome screen greets you with all the necessary options to install it in your system.
+
+![EndeavourOS Welcome Screen][2]
+
+By default, the ISO provides a lightweight Xfce desktop. However, EndeavourOS also provides you with all the desktop environments and window managers (the major ones – see below). And they are all tested to work fine. If you are connected to the internet during installation – you can install these via the Calamares installer. That means you do not need to reinstall them after the base Xfce setup.
+
+Furthermore, if you are a power user and want just a basic Arch Linux to install without any desktop – then that’s also possible. Just use the “No desktop” option during installation!
+
+Although Arch Linux recently created an automated script archinstall to make the installation easier, still faster and easier to get a base Arch Install via the EndeavourOS ISO.
+
+![EndeavourOS installer showing no desktop and other options][3]
+
+Furthermore, you have the option to choose between three options: GRUB, systemd-boot or “no bootloader” – this is one of the highlight features of the EndeavourOS “Cassini” release. In addition, you can also choose the packages you want to install (online mode only). For example, you might need a basic system to start with. Or, you might want to install some apps related to video/audio or development work. All of these you can select in this version.
+
+The installation is smooth and finished by detecting the other operating systems in my test machine. In this “Cassini” release, the team also swapped the mkinitcpio with [dracut][4] for better performance and less failure on boot-related issues.
+
+#### Flagship “Xfce” flavoured desktop experience
+
+After the first login, you are again greeted with the Welcome app with a list of items which you can do “after install”. A very thoughtful addition from the devs. This includes initial tasks of changing wallpaper, updating Arch mirrors, installing NVIDIA drivers, and more. Many Linux distributions bring a Welcome app, but this app is a complete package, IMO.
+
+![After install items in Welcome app][5]
+
+The default look is the best-customized Xfce desktop you can get. It has been customized to be presented as a well-looking distro, far from what default Xfce actually brings in. This includes the GRUB menu, login screen and desktop.
+
+The main Xfce menu is configured with more items, and the terminal is a little transparent and uses the Qogir icon theme. All of these changes are complemented with stunning wallpapers and Arc-Darker default Xfce theme.
+
+![EndeavourOS Cassini Desktop with Xfce 4.18][6]
+
+#### Performance
+
+The performance of Arch Linux is always better, despite the desktop environment. It always feels faster because it doesn’t bring bloated within. On top of that, the [Xfce desktop 4.18][7] brings in additional performance optimization in the “Cassini” release, which you can feel while browsing through the desktop.
+
+At idle, it uses around 700MB of memory and CPU at an average of 4%. This is the baseline. The resource usage may increase based on the number of apps you open. In my earlier reviews of EndeavourOS, the performance is always similar.
+
+Not only that, it uses only 4GB of disk space for the default Xfce installation. However, you may need to install additional heavy software such as LibreOffice, GIMP, or KDenlive, which would take more disk space.
+
+![EndeavourOS performance Cassini][8]
+
+#### How easy is it to perform day-to-day tasks in EndeavourOS
+
+One of the great features of EndeavourOS is some of the python-based GUI tools which make your life easy in Arch Linux. For example, you get notifications for updates from Arch and EndeavourOS repo, one-click software installation from AUR, and update mirrors and your system with one single click. You do not need to run any commands from the terminal. This is a big help for new users of Arch Linux.
+
+![One click installation of software][9]
+
+![Package cleaner and update manager][10]
+
+#### A unique way of handling the rolling release towards stability
+
+Arch Linux being a rolling release distro, tend to break things. For example, some systems may break during the monthly Kernel refresh of the Arch main repo. Due to its popularity and the developers’ proactiveness, you get notifications and a workaround related to the problem if things break.
+
+The recent GRUB issue in Arch Linux, which caused massive boot problems for users, is really [handled well][11] by the EndeavourOS team through proper communication to the users with a workaround.
+
+Hence, you are not really lost if you end up with an unstable system.
+
+In addition, the pacman configuration is customized with EndeavourOS-selected mirrors to ensure your experience is flawless.
+
+#### Official support for open-source hardware and ARM
+
+In this EndeavourOS “Cassini” release, the official support for Pinebook Pro laptops arrives. The team worked on top of Manjaro packages with the Pine64 team to provide exclusive Arch packages for you so that the laptop works out of the box. In addition, EndeavourOS ARM images are also available to download for Raspberry Pi 4.
+
+#### Community help
+
+One of the greatest benefits of EndeavourOS is community help – which is instant! This is mostly for its dedicated [Telegram channel][12], where you get responses to your any EndeavourOS problems within minutes. I have been to the channel, and the mods/contributors are friendly and helpful.
+
+Furthermore, you can also get help from the official forum and other social channels.
+
+### Wrapping Up
+
+While closing this EndeavourOS review of the [“Cassini” release,][13] I would say it’s one of the best-built distros and well-organized. The developers and the team have a clear roadmap to build a general-purpose Arch Linux distro. Also, the vision is clear with the ARM and Pinebook Pro supports and other initiatives.
+
+To summarise, a perfect distro for everyone who wants a longer-running, stable system in Arch Linux.
+
+You can download EndeavourOS from the [official website][14].
+
+Cheers.

+Debugging LibreOffice Basic Macro using Breakpoint and Watch
+======
+
+**A simple guide for you to learn how to debug LibreOffice basic macro using breakpoint and watch.**
+
+While writing complex macros to automate various tasks in LibreOffice, you definitely encounter errors. Some run-time errors are self-explanatory. But some of them are very generic. To debug those, you need to carefully put breakpoints and step through the code to see where the problem is in your code.
+
+Hence this tutorial. These techniques apply to all the macros written in Calc, Writer or Impress. And should be applied to OpenOffice macros as well.
+
+### Debug a LibreOffice Macro written in Basic
+
+It’s easier to demonstrate this concept using an example.
+
+#### Define
+
+Let’s define three variables which we would use for our exercise.
+
+```
+dim i, j, cnt
+```
+
+Define a `for` loop, which would execute from 1 to 10. Inside the loop, increment two variables as below. This is just for just this demo; however, you can put any logic you want.
+
+```
+for cnt = 1 to 10
+ i = i + 1
+ j = i + 1
+next cnt
+```
+
+#### Adding Breakpoint
+
+Now, we want to put two breakpoints in the statement `"for cnt = 1 to 10"` and `"j = i + 1"`. When you put a breakpoint inside your program, it runs in debug mode and holds the execution at the breakpoint.
+
+To put a breakpoint in a LibreOffice Basic macro, put the cursor in the statement. And then, press `F9` or press the below button from the toolbar.
+
+![Breakpoint toolbar button in LibreOffice Macro editor][1]
+
+Once you do that, you will see a red circle on the left side of the statement, which means a breakpoint has been added _to that statement_. See the below image. In addition, you can add multiple breakpoints as per your needs.
+
+![After adding breakpoints][2]
+
+If you want to remove a breakpoint from a statement, press `F9` again in the statement, OR you can `double-click` the red circle.
+
+#### Adding Watch
+
+Now, we would add a ‘watch’ to the variable `"cnt"`.
+
+When the program executes in debug mode, the watch helps monitor a variable’s value between program steps. To add a watch on `"cnt"`variable, select the variable and press `F7` or click the glass icon in the toolbar.
+
+![Watch button in the toolbar in LibreOffice Macro editor][3]
+
+Once you do that, you will see the variable added to the watch list at the bottom of the editor.
+
+![Watch section appears at the bottom of the editor][4]
+
+#### Execute by Step
+
+We are all set with tools.
+
+Run the program by pressing `F5`. As we already added breakpoints, you would see the execution halts at the first breakpoint with a little **yellow arrow**.
+
+![Execution halts at the breakpoint][5]
+
+Now you have two options.
+
+Press `F5` again to continue the execution of the program, and it will halt again at the next breakpoint.Press `F8` (step execution), which would execute step by step, and you can see the ‘watched’ variable `'cnt'` value is changing as below.
+
+Lets press `F8`. You can see the yellow arrow comes to the next statement, and the compiler waits. Now the fun part, if you take a closer look at the watch window, you can see the `'cnt'`variable’s value is 1.
+
+![Variable contents during execution][6]
+
+So this way, you can debug, add breakpoints and add watch any LibreOffice or OpenOffice macro using its editor.
+
+Furthermore, you can add many watch variables as you want and debug your program for successful execution.
+
+### Closing Notes
+
+Although the above example is specific to LibreOffice macros, the same concept applies to programming and debugging in general. I hope this article helps you to understand the basics of debugging, step execution and watch in programming and macros in LibreOffice.

+
+How to migrate your code from PHP 7.4 to 8.1
+======
+
+The end-of-life (EOL) for [PHP 7.4][1] was Monday, November 28, 2022. If you’re like me, that date snuck up much faster than anticipated. While your PHP 7.4 code isn’t going to immediately stop working, you do need to begin making plans for the future of this codebase.
+
+### What are your options?
+
+You could continue to remain on PHP 7.4, but there are several benefits to updating. The biggest are security risk and support. As we move farther and farther away from the EOL date, attackers will turn their focus to PHP 7.4 knowing that any vulnerabilities they discover will go unpatched in the majority of systems. Staying on PHP 7.4 drastically increases the risk of your site being compromised in the future. In a similar vein, finding support for issues you encounter with PHP 7.4 will become increasingly more difficult. In addition, you will most likely begin to encounter compatibility issues with third-party code/packages as they update their code to be compatible with later versions and drop support for 7.4. You’ll also be missing out on significant speed and performance improvements [introduced in 8.0][2] and further [improved in 8.1][3]. But upgrading all that legacy code is daunting!
+
+### Where to start?
+
+Luckily, PHP provides an [official migration guide][4] from PHP 7.4 to 8.0 to get you started (and an [8.0 to 8.1 migration guide][5] as well). Be sure to read through the Backward Incompatible Changes and Deprecated Features sections. While these guides are incredibly handy, you may very well have tens of thousands of lines of code to check, some of which you may have inherited. Luckily there are some options to help pinpoint potential problem areas in the migration.
+
+#### PHPCodeSniffer + PHPCompatibility sniffs
+
+[PHPCodeSniffer][6] (PCS) is a package for syntax checking of PHP Code. It checks your code against a collection of defined rules (aka “sniffs”) referred to as “standards”. PHPCodeSniffer ships with a collection of standards you can use including PEAR, PSR1, PSR2, PSR12, Squiz, and Zend. Luckily, you can write your own collection of sniffs to define any set of rules you like.
+
+> PHPCompability has entered the chat
+
+[PHPCompatibility][7] “is a set of sniffs for PHP CodeSniffer that checks for PHP cross-version compatibility” allowing you to test your codebase for compatibility with different versions of PHP, including PHP 8.0 and 8.1. This means you can use PHPCodeSniffer to scan your codebase, applying the rules from PHPCompability to sniff out any incompatibilities with PHP 8.1 that might be present.
+
+### Before I continue…
+
+While PHP8.2 was released on [December 8, 2022][8], and I encourage you to begin looking over the [official 8.1 to 8.2 migration guide][9] and begin making plans to upgrade, most of the checkers I mention in this article have not completed full support for 8.2 at this time. For those reasons, I’ll be focusing on migrating the code to PHP8.1, and not 8.2.
+
+In the process of writing this article, I discovered PHPCompatiblity has a [known issue][10] when checking for compatibility with PHP 8.0/8.1 where it will report issues that should be **Errors** as **Warnings**. The only workaround for now is to use the `develop` branch for PHPCompatibility instead of `master`. While they state it is stable, please be aware that in this article, I’m using the non-stable branch. You may want to weigh the pros and cons of using the `develop` branch before implementing it anywhere else than in a local development environment. While I found PCS+PHPCompatibility to be the most straightforward and comprehensive solution for checking for incompatible code, if you do not want to use a non-stable version of PCS, see the section at the end of the article about alternative options.
+
+For the purposes of this article, I’ll be using the [1.4.6 version of SimpleSAMLphp][11] to test for incompatibilities. This is a six-year-old version of the code base. I do this not to pick on SimpleSAMLphp, but because I wanted something that would _definitely_ have some errors. As it turns out, all of the platform.sh code I tested, as well as my own code was already compatible with PHP8.1 and required no changes.
+
+### Get started
+
+To get started, first clone your codebase, and then create a new branch. You’ll now need to decide if you want to install the dependencies and run the scans on your local machine or in a local development environment using something like [DDEV][12], [Lando][13], or [Docksal][14]. In this demo, I’m using DDEV. I suggest using a local development environment vs running directly on your local machine because while it’s not required to use the version of PHP you want to test against, for the best results, it is recommended you do so. If you don’t have PHP installed, or don’t have the target version installed, a local development environment allows you to create an ephemeral environment with exactly what you need without changing your machine.
+
+After setting up your environment for PHP 8.1, at a terminal prompt (in my case, I’ve run `ddev start` and once the containers are available, shell into the web app using `ddev ssh`), you need to add these new packages so you use them to test with. I’ll be adding them with composer, however, there are [multiple][15][ways][16] to [install][17][them][18] if you would prefer to do so differently. If your codebase isn’t already using composer, you’ll need to do [composer init][19] before continuing.
+
+Because you'll be using the develop branch of PHPCompatibility there are a couple of extra steps to do that aren’t in the regular installation instructions. First is that the develop branch of PHPCompatibility requires an alpha version of `phpcsstandards/phpcsutils`. Because it is marked as alpha, you'll need to let composer know this one package is OK to install even though it is below your minimum stability requirements.
+
+`$ composer require --dev phpcsstandards/phpcsutils:"^1.0@dev"`
+
+Next, install PHPCompatibility targeting the `develop` branch
+
+`$ composer require --dev phpcompatibility/php-compatibility:dev-develop`
+
+The `develop` branch also installs `dealerdirect/phpcodesniffer-composer-installer` so you don’t need to add it manually or direct PCS to this new standard.
+
+To verify our new standards are installed, you'll have PCS display the standards it is aware of.
+
+```
+$ phpcs -i
+The installed coding standards are MySource, PEAR, PSR1, PSR2, PSR12, Squiz, Zend, PHPCompatibility, PHPCS23Utils and PHPCSUtils
+```
+
+Now that you know your standards are available, you can have PCS scan our code. To instruct PCS to use a specific standard, use the `--standard` option and tell it to use `PHPCompatibility`. However, you also need to tell PHPCompatibility which PHP version you want to test against. For that, use PCS’ `--runtime-set` option and pass it the key `testVersion` and value of `8.1`.
+
+Before you start the scan, the one issue remaining is that code you want to scan is in the root of the project (`.`) but the `vendor` directly is also in the project root. You don’t want the code in `vendor` scanned, as those aren’t packages you necessarily control. PCS allows you to tell it to not scan files/directories with the `--ignore` option. Finally, you want to see the progress as PCS parses the file so you'll pass in the `-p` option.
+
+Putting it all together:
+
+`$ phpcs -p . --standard=PHPCompatibility --runtime-set testVersion 8.1 --ignore=*/vendor/*`
+
+This kicks off PCS which will output its progress as it scans through your project’s code. `W` indicates **Warnings**, and `E` indicates **Errors**. At the end of the scan it will output: a full report with the file containing the issue, the line number where the issue occurs, whether the issue is a **Warning** or an **Error**, and the specific issue discovered.
+
+In general, **Errors** are things that will cause a fatal error in PHP 8.1 and will need to be fixed before you can migrate. **Warnings** can be things that have been deprecated in 8.0/8.1 but not yet removed or issues that PCS ran into while trying to parse the file.
+
+![asciicast][20]
+
+Given that the report might be long, and is output all at once into your terminal, there are [numerous options][21] for changing the information that is included in the report, as well as multiple reporting formats.
+
+As you begin to fix your code, you can rerun the report as many times as needed. However, at some point, you’ll need to test the code on an actual PHP8.1 environment with real data. If you’re using [Platform.sh][22], which is as easy as creating a branch, changing a single line in your configuration file, and pushing that branch to us. You can check out [this video][23] to see how easy it is!
+
+### There’s too much to fix!
+
+Now that you have a solid idea of what needs to be updated before you can migrate, you might be facing an incredible amount of work ahead of you. Luckily, you have some options to help you out. PCS ships with a code fixer called [PHP Code Beautifier and Fixer][24] (`phpcbf`). Running phpcbf is almost identical to running phpcs and most of the options are identical. The other option is [Rector][25]. Usage of these tools is beyond the scope of this article, but as with any automation, you’ll want to test and verify before promoting changes to production.
+
+### Alternative options
+
+If for any reason you don’t feel comfortable using a non-stable version of PCS, you do have other options for checking your code.
+
+#### Phan
+
+Phan is a static code analyzer for PHP. It offers multiple levels of analysis and allows for incrementally strengthening that analysis.
+
+“Static analysis needs to be introduced slowly if you want to avoid your team losing their minds.”
+
+Phan doesn’t target just compatibility with newer versions, it can highlight areas of code that will error in later versions. However, there are some caveats when using Phan for checking compatibility:
+
+- Slower than PCS+PHPCompatibility.
+- Phan requires the [ast php extension][26] which is not available by default on Platform.sh (or in DDEV). You’ll need to install it in your local development environment and add it to your php.ini file. Alternatively, you can use the `--allow-polyfill-parser` option, but it is considerably slower.
+- Phan’s default reporting output isn’t as easy to read as other options
+- I came across an issue where if your code base sets a different `vendor` directory via composer’s `[config:vendor-dir](https://getcomposer.org/doc/06-config.md#vendor-dir)` option, it will error out stating it can’t find certain files in the `vendor` directory
+- As mentioned, Phan analyzes much more than just PHP8.1 compatibility. While certainly a strength in other situations, if your goal is to migrate from 7.4 to 8.1 as quickly as possible, you will have to parse through errors that are unrelated to version compatibility.
+- Requires you run it on the PHP version you want to target
+
+#### PHPStan
+
+Similar to Phan, PHPStan is a static code analyzer for PHP that promises to “find bugs without writing tests.” And a similar set of caveats apply:
+
+- Slower than either PCS or Phan
+- Analyzes much more than just PHP8.1 compatibility so depending on your current codebase, you will have to possibly parse through a bunch of errors that are unrelated to version compatibility
+- Requires you run it on the PHP version you want to target
+
+#### PHP Parallel Lint
+
+A very fast PHP linter that can lint your codebase for issues, but can also check for deprecations. While it is exceptionally fast, it is only a linter, and therefore can only surface deprecations that are thrown at compile time, not at runtime. In my example code, it only found 2 deprecations vs the 960 deprecations PCS uncovered.
+
+### Summary
+
+Code migrations, while never fun, are crucial to minimizing organizational risk. Platform.sh gives you the flexibility to test your code using the same data and configurations as your production site, but in a siloed environment. Combine this with the tools above, and you have everything you need for a strong, efficient code migration.

+
+My 4 favorite features of the 4pane file manager on Linux
+======
+
+4Pane is a multi-pane file manager for Linux that allows for customized layout, and provides quick access to traditional desktop conveniences as well as common Linux tools. 4Pane aims for speed over visual effects, and places the way you want to work above all else. In honor of its name, I've got a list of my four favorite features of this fine file manager.
+
+### 1. Flexible interface
+
+![The 4Pane file manager is a fast multi-pane application for managing files.][1]
+
+The most prominent feature of the 4Pane window is the same as its name: there are four panes in the window by default. In a way, though, there's actually only two, or said another way, each of the two panes is divided into two columns. The column on the left is a directory tree of your current location (home, by default.) Files are never displayed in the left column. It's only a directory tree.
+
+The adjacent column displays the contents of the selected directory. When you double-click on a file, it opens in its default application. When you double-click on a directory, that directory is revealed in the left column and the right column displays its contents.
+
+This same model is duplicated in the other window pane.
+
+4Pane only has 4 panes by default, but it doesn't enforce that view. If you're overwhelmed by the four-pane view, click on the **View** menu and select **Unsplit panes**. This displays just one pane of two columns. It's a simplified view compared to what's possible, but it's a nice place to start while you're getting used to the column-style for browsing files.
+
+#### Splitting panes
+
+The advantage of a split view is that you don't have to open another window to drag and drop a file or folder from one location to another. This isn't the predominant model for file managers, but it's a popular subset. 4Pane is one of the few, in my experience, that recognizes that it's not always convenient to work laterally. If you prefer to have your second pane at the bottom of the window, go to the **View** menu and select **Split panes horizontally** (meaning that the _split_ is horizontal, so the panes are situated vertically to one another).
+
+![You can create horizontal splits in 4Pane.][2]
+
+### 2. Tooltip preview
+
+One of my favorite features of 4Pane is the tooltip preview. To activate this, click the photo icon in the top toolbar. With this active, all you have to do is roll your mouse over a file to see a preview of its contents in a tooltip. It may not be a feature you want active all the time. The tooltips can be distracting when you're just browsing files. However, if you're looking for something specific or if you're just not sure exactly what's in a directory, a quick wave of your mouse to get an overview of the contents of several files is satisfyingly efficient.
+
+### 3. Menu
+
+The menu bar of 4Pane isn't quite like most file manager menu bars you may be accustomed to. There's a menu dedicated to archiving actions, mounting devices, and popular Linux commands such as [grep][3] and [find][4].
+
+For instance, in the **Archive** menu, you can choose to extract an archive or compressed file, create a new archive, add a file to an existing archive, compress a file, and more. I love [Ark][5] and similar utilities, but I also recognize how useful it is for a file manager to make those utilities unnecessary. Especially when you're on an [old computer][6], the fewer applications you have to launch, the better.
+
+Also impressive are the built-in front ends for `grep` and `find`. I'll admit that I probably won't use it often myself, but I never complain when a developer brings the power of Linux commands to users who aren't [yet] familiar with the terminal.
+
+![4Pane can run grep and locate commands to help you find your data.][7]
+
+The `locate` front end is probably the most useful of the bunch. It's fast and effective. There's just one field in the dialogue box, so it makes a file system search _fast_.
+
+For example, say you're searching for the file `Zombie-Apocalypse-Plan-B.txt` because Plan A fell through, but in the heat of the moment (what with zombies knocking down your door, and all) you can't remember where you saved it. Go to the **Tools** menu and select **locate**. Type `zombie` in the search field, click the `-i` box so that your system ignores capitalization, and click **OK**. This returns both `Zombie-Apocalypse-Plan-A.txt` and `Zombie-Apocalypse-Plan-B.txt`.
+
+Maybe that's good enough for you, or maybe you need a little more precision. In addition to `-i` for case insensitivity, you can click the `-r` option to leverage the power of [regex][8]. Type `zombie.B.` to narrow your search to a file starting with `zombie` and containing the letter `B` somewhere in the filename.
+
+Effective and fast.
+
+### 4. Undo
+
+Finally, my (other) very favorite feature of 4pane is the **Undo** button. When you right click on a file or folder and select **Delete**, the item is sent to a secret location (it's not actually secret, but it's out of sight and out of mind). The item isn't scrubbed from the hard drive until you close the 4pane window. Up until then, you can always click the **Undo** button in the top toolbar to reverse decisions you've come to regret.
+
+This is a separate action from sending a file to your system trash, so it _is_ meant to masquerade as an actual delete action. The difference is that it's a delayed delete. That may not suit you. Some users are disciplined enough to send files to the system trash, but others skip the trash. This feature is designed to protect you from yourself by delaying deletion until you close the window. I find it a reasonable and invaluable feature, and it's the one feature that I've already benefited from several times.
+
+### Install 4Pane on Linux
+
+If you're sold on 4Pane, or at least curious about it, then you should install it and try it out! On Linux, your distribution may package 4Pane in its software repository. If so, you can use your package manager to install. For example, on Fedora, Mageia, OpenMandriva, and similar:
+
+```
+$ sudo dnf install 4pane
+```
+
+On Debian and Debian-based systems:
+
+```
+$ sudo apt install 4pane
+```
+
+If your distribution doesn't carry 4Pane, you can download it from [4pane.co.uk][9].
+
+Once installed, launch 4Pane from your application menu.

+11 New Distros to look forward to in 2023
+======
+
+What are you looking forward to in 2023? Try these distros!
+
+![11 New Distros to look forward to in 2023][1]
+
+It's time to say goodbye to 2022! 📆
+
+There were many distro releases in 2022, some more extraordinary than others.
+
+With the trend shifting towards focusing more on the user experience and performance side of things, Linux distributions have significantly evolved over the past year.
+
+As for you, the end-user, you now have several options. You can try some [beginner-friendly options][2] or [distros for advanced users][3].
+
+Here, I focus on new options that you can give a try. These distros may not necessarily replace the popular distributions available. But if you want to try something new and different, feel free to go through the list.
+
+So, what can you expect in 2023? 🤔
+
+Well, to answer that. Allow me to take you on a distro journey!
+
+> 💡 New distributions may not be suitable for production use cases. Try these options if you have no issues taking a leap of faith to experiment.
+
+### 1. Vanilla OS
+
+![vanilla os][4]
+
+Vanilla OS is an Ubuntu-based distro that is the brainchild of Mirko Brombin, the creator of [Bottles][5].
+
+It aims to provide a **clean, vanilla GNOME experience with on-demand immutability** and an exceptional first-time setup experience.
+
+You can check it out if you want something new and want to try out the on-demand immutability features that make Vanilla OS so unique.
+
+It is yet to receive a stable release (soon) and is set to receive many improvements in 2023.
+
+[Vanilla OS][6]
+
+### 2. XeroLinux
+
+![xeroxlinux][7]
+
+Steve a.k.a. TechXero, started [XeroLinux][8] as a passion project that was not meant to be a mainstream distro with all the bells and whistles.
+
+An **'eye-candy' version of Arch Linux** offers a pleasant out-of-the-box experience with a few exciting features.
+
+You can try this if you want a more accessible Arch Linux experience.
+
+**From January 2023**, XeroLinux will be switching to a monthly release schedule. So, you can expect plenty of updates in 2023!
+
+[XeroLinux][9]
+
+### 3. Crystal Linux
+
+![crystal linux][10]
+
+Crystal Linux is an upcoming Arch-based distro that wants to **provide an easy-to-use desktop experience coupled with modern Linux technologies**.
+
+In its current form, it may not be welcoming to newcomers, and people with experience using Linux are likelier to like it.
+
+So, for now, I would suggest users who are already familiar with Linux give Crystal Linux a try.
+
+I expect Crystal Linux to have a stable release sometime in 2023 with many features and improvements over the [beta version][11] that is available right now.
+
+[Crystal Linux][12]
+
+#### Recommended Read 📖

+![tuxedo os][13]
+
+[TUXEDO OS][14] is an Ubuntu-based offering from TUXEDO Computers, a Linux-focused hardware manufacturer.
+
+It features the KDE Plasma desktop environment with extras like **TUXEDO Control Center** to fine-tune your hardware and **TUXEDO Tomte**, a configuration service for resolving driver/missing package issues.
+
+I suggest you try this if you want a **different KDE-powered experience**.
+
+Initially, it was only made available as a pre-installed operating system on TUXEDO laptops and computers.
+
+But later, it received a general use release back in September 2022 dubbed as 'TUXEDO OS 1'. It is set to receive plenty of updates in 2023.
+
+[TUXEDO OS][15]
+
+### 5. EuroLinux
+
+![euro linux][16]
+
+An RHEL-based distro with **enterprise perks** is what [EuroLinux][17] is. It provides stability and security in a solid package.
+
+Based on **RHEL 9**, it can provide seamless compatibility with other [RHEL-based server distros][18] such as Rocky Linux, CentOS, AlmaLinux, and more.
+
+It aims to lure in Windows and macOS users with a familiar user interface layout with its implementation of a translucent dock at the bottom of the screen.
+
+You should try this because the overall package is quite adequate and can cater to both Linux and Windows/macOS users.
+
+It is now available as stable release, with updates planned for 2023.
+
+[EuroLinux Desktop][19]
+
+### 6. Zinc
+
+![zinc][20]
+
+[Zinc][21] is an **Ubuntu-based distro** that has been tweaked to provide a unique experience. Existing Ubuntu users may be surprised to see what it has to offer.
+
+Based on the latest LTS release of **Xubuntu**, it uses the XFCE desktop environment with numerous improvements, such as integrated Linux AppImage support, deb-get package installer, BTRFS as the default file system, and more.
+
+This distro can be a viable alternative to replace your daily driver, provided it is set up correctly.
+
+It follows a stable release model, so you can expect significant updates in 2023!
+
+[Zinc][21]
+
+### 7. CachyOS
+
+![cachyos][22]
+
+[CachyOS][23] tries to make **Arch Linux a beginner-friendly affair** that anyone can use. It is popular because of its high level of customizability and also because it has the newest software.
+
+It aims to provide you with a fast and secure operating system that is easy to use.
+
+This OS is for users who want to experiment and try something new.
+
+CachyOS is a rolling-release distro, so you can expect it to receive a ton of updates in 2023.
+
+[CachyOS][23]
+
+### 8. risiOS
+
+![risios][24]
+
+In a sea of Arch and Ubuntu-based Linux distros, [risiOS][25] is a rare sight to see.
+
+Based on Fedora Linux, the project saw its beginnings in Seattle, USA.
+
+It uses the **GNOME desktop environment** to provide users with a highly customizable experience with a **customized ZSH version**.
+
+If you want to try a Fedora-based distro, this can be something new for you!
+
+risiOS gets a stable release with minor updates pushed in between. It has much more to give in 2023.
+
+[risiOS][25]
+
+### 9. Exodia OS
+
+![exodia os][26]
+
+Another Arch-based Linux distro!#$**?
+
+Yes. 🤭 Well, it looks like this year, we have had enough of Arch-based distros, which is not necessarily bad!
+
+Meet [Exodia OS][27], an Arch-based Linux distro that aims to be highly customizable for users in cybersecurity fields.
+
+Its feature set includes pre-installed **tools for all cybersecurity fields, TUI Apps, ElKowars wacky widgets (EWW), zsh, and more**.
+
+If you are a cybersecurity expert or an enthusiast, you can give this a try!
+
+They offer three releases for different use cases. You can expect them to keep pushing essential updates and feature additions in 2023.
+
+[Exodia OS][27]
+
+### 10. Kumandar Linux
+
+![kumander linux][28]
+
+At first glance, you would think that it is Windows 7, but if you look closer, you will find that it is [Kumandar Linux][29].
+
+It is based on **Debian 11 and uses a customized version of XFCE**.
+
+The name stands for 'Commander' in English and pays homage to the developer's first computer, the [Commodore VIC20][30].
+
+If you liked the Windows 7 experience but wanted the same thing on Linux. Then you can give this a try!
+
+Currently, only the early-release candidate has been released. But you can expect a stable release in 2023, hopefully!
+
+[Kumander][29]
+
+### 11. Ubuntu Unity
+
+![ubuntu unity][31]
+
+Declared as an official flavor of Ubuntu [earlier this year][32], Ubuntu Unity is a remix of Ubuntu.
+
+It features the **Unity desktop interface** used in Ubuntu from 2010-2017, which was dropped in favor of GNOME.
+
+The development has been in full swing, with the young lead developer pushing updates and feature additions.
+
+Users who want to try a different flavor of Ubuntu can give this a shot. It offers both LTS and non-LTS releases.
+
+[Ubuntu Unity][33]
+
+**So, wrapping up.**
+
+Even with this comprehensive list, I may have missed out on some. 🤔
+
+But.
+
+Maybe a surprise release will take the headlines in 2023, or some existing distro will try something different.
+
+Until then.
+
+_💬 Do tell me what distribution you are excited about in 2023?_

+
+11 tips for writing a good Git commit message
+======
+
+Lately, I have been paying closer attention to the changelogs I get from products and services when updates are needed. Here are some examples:
+
+- Fixed some bugs.
+- Made some accessibility improvements.
+- We've made improvements and fixed bugs for a smoother ride.
+
+When I think about some of the first commit messages I made as a junior developer I have to hang my head in dismay:
+
+- Pointed and clicked around a bit and now things seem to work.
+- Did what programmer X told me to do and now the banner is blue.
+
+This can be frustrating! I asked our community of contributors the following questions:
+
+- What makes a good Git commit message?
+- What makes a bad one?
+- What rules do you think a project should have around what a commit message contains?
+
+Here are their answers:
+
+### Great writing is key
+
+As with anything you write, you should think about who is going to read it. Then adapt the amount and depth of information accordingly.
+
+Improving your natural language and writing skills is essential for a healthy career in software development. It's not just code that counts.
+
+**—[Camilla Conte][1]**
+
+### Be descriptive and don't assume
+
+I spend a lot of my time collaborating in the [OpenStack][2] community, and its code reviewers have some fairly exacting standards compared to what I see from other projects "in the wild."
+
+I'll often spend far longer composing a solid commit message than I do writing the actual code implementation or fix. Sometimes commit messages can end up many times longer than the diffs they're explaining.
+
+To summarize some of the contributor guidance:
+
+- Describe why a change is being made, not just what is changing
+- The first commit line is the most important (like the subject line of an email)
+- Don't assume reviewers understand the original problem you're fixing
+- Don't assume the reviewer has access to external web services or the site (summarize defect reports and other relevant discussions)
+- Don't assume the code is self-evident and self-documenting (though there is no need to repeat points you also make in your code comments)
+- Don't include information only relevant to earlier revisions of the change (we expect contributors to squash revisions together and edit their commit messages accordingly).
+
+There's a brief section on the topic in the OpenStack Contributors Guide: [https://docs.openstack.org/contributors/common/git.html#commit-messages][3]
+
+**—[Jeremy Stanley][4]**
+
+### Your future self will thank you
+
+I cannot agree more with Jeremy. +1000
+
+Jeremy said, "describe why a change is being made, not just what's changing."
+
+Imagine you're someone else, in a faraway future, trying to work out this commit.
+
+Put yourself in other people's shoes, as the old saying goes.
+
+**—[Leigh Morresi][5]**
+
+### Use the bug ID
+
+I recommend adding the bug ID at the start of the commit message so that it's easier to track the commits at a later stage using the [`grep` command][6].
+
+For example:
+
+```
+$ git commit -m "BZ#19xxxxx
+```
+
+To come up with thoughtful commits, consider the following:
+
+- Why have I made these changes?
+- What effect have my changes made?
+- Why was the change needed?
+- What are the changes in reference to?
+
+**—[Agil Antony][7]**
+
+### Tell the whole story
+
+I like to imagine there is a hidden prefix to every commit message that reads "By applying this."
+
+A good commit message includes exactly what will happen and why. It is insufficient to merely have the work ticket reference because that decentralizes the information; Git is decentralized. As a software developer, I want to know why the proposed changes are being considered. What specific problem is being addressed? What alternate solutions were considered (and discarded)? What unexpected things were discovered during the creation of the changeset that influenced the current content?
+
+There's no prize for shortest commit message. Your future self and future colleagues will appreciate you going into depth to explain the problem and why this changeset is the answer. Harness those cooking blogs where there's a five-paragraph life story. Here, however, make the problem the subject of the life story.
+
+**—[Lisa Seelye][8]**
+
+### But don't be overly verbose
+
+A good git commit message contains information about what was done, and nothing else. For instance, if you needed to update the .gitignore, just say "updated .gitignore." Folks can dive into the commit itself for more details. It doesn't need to be verbose.
+
+A bad commit message is something like, "oh crap" or "try this". Granted, I've been guilty of this, but it doesn't help anyone if they need to look at commits at a glance.
+
+Rules are very subjective. They can differ from lead to lead and team to team. But at the very least, give some contextual information about the commit. Especially if it's a large one. No one has time to skim through 1000+ files with a heavy change history.
+
+**—[Miriam Goldman][9]**
+
+### Use present tense
+
+I like project manager-styled commit messages written in present and not future terms (for example, "add" instead of "added"). However, it's usually only possible if commits are frequent. There's only so much "how did I do it" you can remember when you're faced with a deadline. Yet, well-written commits not only help collaborators, but are also helpful to the committer in recollecting history.
+
+**—[Chris Okpada][10]**
+
+### Don't rely on links
+
+One thing I like to remind colleagues of is that you're not just explaining to the people who are going to decide whether to approve your commit. You're also explaining to future developers and users who have found this commit in a bisect or blame operation and are trying to understand its relevance.
+
+If the only context supplied is a link to some external system, and that far in the future the system it links to is no longer in use or has otherwise become inaccessible to that individual, your commit message has been rendered useless and may just as well be blank.
+
+All too often, I go digging in the Git history of some open source project, and find commit messages which are nothing more than a bug ID or a link to some company's internal and private defect tracker.
+
+Don't be that project!
+
+**—[Jeremy Stanley][4]**
+
+### Clear and concise changelogs
+
+As a release communications manager, I often read the entire release board. I also met with developers to discuss any areas that weren't clear yet. Then I tested the release early. After that, I would write a release post by sourcing the changelogs and corresponding revised or new content.
+
+The changelogs are personal reminders for developers, but also have corresponding issues and tickets for them. You should capitalize product names appropriately, use a spell checker, be consistent with punctuation, and sentence structure. The lead developer should proofread these as well. Your customers, that are developers, are reading these. What information should they know before running the update to better serve their customers?
+
+**—[Courtney Robertson][11]**
+
+### Be specific
+
+As a frequent release manager, I like messages that name the component a commit touches, and a brief description of what was changed. Also having a reference back to where the request for this work came from helps to tie fixes together long after we forgot about your clever branch name.
+
+- "fix fatal error" is not ideal.
+- "ISS-304: Fix fatal error in Login Access Control function for users
+ with the Partner role" is better.
+- "ISS-304: Login Access Control: fix fatal error in getPartnerId()" is
+ better still.
+
+I can look at the entire relationship between a Git commit, branch, merge commit, and inspect the individual lines and files that were changed. But I don't have that kind of time in the middle of a release. I want to be able to relate back to the source of this work in the project management tool, have some idea of which components are being changed, and in what way.
+
+**—[Ryan Price][12]**
+
+### Make it a habit
+
+My favorite commit that I'm guilty of is, "commit before I switch branches" because I have to work on something else more urgent. Sometimes, I need to commit my current work to a totally different project. My manager's strategy is to have us work as we normally do. But then when we rebase, he wants us to squash commits where it makes sense and write better messages. I can't say we always do this, but his method does make sense.
+
+I have a lot of "this is broken don't know why" type messages too (haha) where I try things but want to commit that attempt before I try something else in case method A was closer to fixing the issue than method B. Writing code is a hot mess. And I've been writing it for over 10 years.
+
+**—[RachieVee][13]**

+Colorblind Filters: GNOME Extension to help Colorblind Users
+======
+
+**A nice GNOME Extension – Colorblind Filters, brings many options for color-blind users.**
+
+Accessibility is a critical aspect of computing and operating systems. It includes well-managed settings for vision impairment, color blind and many other health symptoms. Popular Linux desktop environments such as GNOME and KDE Plasma feature accessibility settings to help all those scenarios.
+
+Thanks to the GNOME Extensions ecosystem, a huge number of specialised extensions are available to aid those users. One of the extensions I came across is [“Colorblind Filters”][1].
+
+### Colorblind Filters – GNOME Extension
+
+As per Wikipedia, _“Colour blindness usually involves the inability to distinguish between shades of red and green. There is no treatment for inherited colour blindness. If colour blindness is caused by another condition, treating the underlying cause can help.”_.
+
+So, it’s important that you have options to tweak settings on your Linux desktop.
+
+#### Set up extensions and flatpak
+
+First, make sure you have Flatpak and GNOME Extensions enabled. And the Extensions manager is installed. You may refer to this detailed guide on how to [set up flatpak][2] & enable [GNOME extensions][3], Or run the following commands (for Ubuntu, Linux Mint, etc.) from the terminal.
+
+```
+sudo apt install flatpaksudo apt install gnome-software-plugin-flatpakflatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakreporeboot
+```
+
+Fedora users, use the below commands.
+
+```
+sudo dnf install flatpaksudo dnf install gnome-software-plugin-flatpakflatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakreporeboot
+```
+
+Once done, install the Extension Manager:
+
+```
+flatpak install com.mattjakeman.ExtensionManager
+```
+
+#### Install the Extension
+
+Open the extension manager from the application menu. Search for “colorblind”. And install the extension (see the below image).
+
+![Install the extension][4]
+
+After installation, you can see a small eye icon on the system tray. You can click on it to enable the pre-defined color filters.
+
+![Colorblind Filters extension tray icon][5]
+
+Right-click on the eye icon for more settings. This extension brings all the necessary customizations for colorblind collections, simulations and additional options. The following options are currently available:
+
+- Protanopia
+- Deuteranopia
+- Tritanopia
+
+- Corrections & Simulations (with high contrast)
+
+- Channel mixer for GBR and BRG
+- Lightness inversion
+- Color Inversion
+
+- Additional tweaks
+
+![Colorblind Filters - options][6]
+
+Use the one that suits you best for your eye.
+
+### Wrapping Up
+
+I think Apple’s macOS and iOS have implemented better accessibility than Windows or Linux. However, Linux Desktops are not far behind with these apps and extensions. Also, there are specialized Linux distributions such as “[Accessible Coconut][7]“, which has been built for specialized needs.
+
+I hope Colorblind gnome extension helps you with your day-to-day usage of Linux and GNOME desktops.
+
+Cheers.

+Document with BookStack, an open source Confluence alternative
+======
+
+BookStack is an open source, web-based documentation system, that allows you to create a structured knowledge store for personal, team, or company use. BookStack focuses on ease-of-use and design to provide an experience suitable for an audience with, potentially, mixed skills in technology. It's built upon the PHP framework Laravel, with MySQL or MariaDB used as a datastore.
+
+I built BookStack after attempting to find a documentation or wiki system for my workplace. [Confluence][1] was the closest option to suit my requirements but the user-based pricing introduced a barrier. The closed nature of Confluence also raised questions to the longevity of the documentation I'd be building. In the end, I decided to build my own platform to suit my needs. I released it under the MIT license to give back to the open source community that I'd come to love and benefit from over the years.
+
+### Content hierarchy and organization options
+
+To keep things familiar and intuitive, BookStack makes use of real-world book terms to describe its organization structure. Documentation content is created as a "Page":
+
+- Pages belong to a specific "Book".
+- Within a Book, Pages can optionally be grouped up into "Chapters".
+- As your documentation grows, you can then use "Shelves" to categorize Books, with Books being able to be part of multiple shelves if needed.
+
+This structure sits at the heart of BookStack, and can often be the love-it-or-hate-it deciding aspect of whether BookStack is suitable for your use case.
+
+Upon this core hierarchy, BookStack also provides tagging, user favorites, and advanced search capabilities to ensure content remains discoverable.
+
+### Writing documentation
+
+The primary method of writing documentation in BookStack is through the use of its what-you-see-is-what-you-get (WYSIWYG) editor, which makes use of the open source [Tiny][2] project. This editor provides a range of content formats including:
+
+- Various header levels
+- Code blocks
+- Collapsible blocks
+- Tables
+- Images
+- Links
+- iFrame embeds
+- Alert callouts
+- Bullet, numbered and tasks lists
+- Drawings (through intregration with the open source [diagrams.net][3])
+
+If you prefer [Markdown][4], you can use the built-in Markdown editor, which provides a live preview and supports the same feature set as the WYSIWYG editor. If permission allows, you can even jump between these editor options depending on the page you're editing.
+
+### How your data is stored
+
+Documentation is stored within a [MySQL or MariaDB][5] database in a relatively simple HTML format, in addition to the original Markdown content if Markdown was used. A lot of design and development decisions have been made to keep this HTML format simplistic. It uses plain standard HTML elements where possible, to ensure raw documentation content remains open and portable.
+
+Uploaded images, attachments, and created drawings are saved on the local filesystem but can optionally be stored in an s3-compatible datastore like the open source [MinIO][6].
+
+To keep your content accessible, there are built-in options to export content as PDF, HTML, plain text, or Markdown. For external consumption, there's a HTTP REST API and a webhook system. In terms of extension, a "logical theme system" allows running of custom PHP code upon a wide range of system events.
+
+### Ready for business
+
+BookStack comes with a range of features to support business environments. Support for a range of authentication options are built-in, including SAML2, OpenID Connect, and LDAP allowing easy single-sign-on usage with platforms such as [KeyCloak][7]. MFA options are available and can be mandated based upon role. An audit log provides full visibility of modification activities across an instance.
+
+A full role-based permission system provides administrators full control over create, view, update, and delete actions of system content. This allows per-role system defaults, with options to set custom permissions on a per-hierarchy item basis.
+
+### A community of support
+
+After being active for over 7 years, the community for BookStack has grown with various avenues for discussion and support. We now have:
+
+- [Our documentation site][8]
+- [Video guides on YouTube][9]
+- [A subreddit][10]
+- [An active GitHub issues list][11]
+- [Paid-for business support][12]
+
+If you want to play with BookStack, you can try it out [on our demo site][13]. To learn how to set up your own instance, visit the [installation page of our documentation][14].

+
+Learn to code with my retro computer program
+======
+
+I teach university courses part-time, including a class about general computing topics, open to all majors. This is an introductory course that teaches students about how technology works, to remove the mystery around computing.
+
+While not a computer science course, one section of this course covers computer programming. I usually talk about programming in very abstract terms, so I don't lose my audience. But this year, I wanted my students to do some "hands-on" programming in an "old school" way. At the same time, I wanted to keep it simple, so everyone could follow along.
+
+I like to structure my lessons to show how you got from "there" to "here." Ideally, I would let my students learn how to write a simple program. Then I would pick it up from there to show how modern programming allows developers to create more complex programs. I decided to try an unconventional approach — teach the students about the ultimate in low-level programming: machine language.
+
+### Machine language programming
+
+Early personal computers like the Apple II (1977), TRS-80 (1977), and IBM PC (1981) let users enter programs with a keyboard, and displayed results on a screen. But computers didn't always come with a screen and keyboard.
+
+The Altair 8800 and IMSAI 8080 (both made in 1975) required users to enter a program using "switches and lights" on a panel. You would enter an instruction in machine language, using a bank of switches, and the machine would light up the ones and zeros of each binary instruction using LEDs.
+
+![Image of an Altair 8800 Computer.][1]
+
+Programming these early machines required knowing the machine language instructions, called opcodes, short for operation codes, to perform basic operations like adding two numbers or storing a value into the computer's memory. I wanted to show my students how programmers would enter a series of instructions and memory addresses by hand, using the switches and lights.
+
+However, using an actual Altair 8800 would be too much overhead in this class. I needed something simple that any beginner-level student could grasp. Ideally, I hoped to find a simple "hobby" retro computer that worked similarly to the Altair 8800, but I couldn't find a suitable "Altair-like" device for less than $100. I found several "Altair" software emulators, but they faithfully reproduce the Altair 8800 opcodes, and that was too much for my needs.
+
+I decided to write my own "educational" retro computer. I call it the Toy CPU. You can find it on my [GitHub repository][2], including several releases to play with. Version 1 was an experimental prototype that ran on [FreeDOS][3]. Version 2 was an updated prototype that ran on Linux with [ncurses][4]. Version 3 is a FreeDOS program that runs in graphics mode.
+
+### Programming the Toy CPU
+
+The Toy CPU is a very simple retro computer. Sporting only 256 bytes of memory and a minimal instruction set, the Toy CPU aims for simplicity while replicating the "switches and lights" programming model. The interface mimics the Altair 8800, with a series of eight LEDs for the counter (the "line number" for the program), instruction, accumulator (internal memory used for temporary data), and status.
+
+When you start the Toy CPU, it simulates "booting" by clearing the memory. While the Toy CPU is starting up, it also displays `INI` ("initialize") in the status lights at the bottom-right of the screen. The `PWR` ("power") light indicates the Toy CPU has been turned on.
+
+![Image of start screen for the toy cpu.][5]
+
+When the Toy CPU is ready for you to enter a program, it indicates `INP` ("input" mode) via the status lights, and starts you at counter 0 in the program. Programs for the Toy CPU always start at counter 0.
+
+In "input" mode, use the up and down arrow keys to show the different program counters, and press Enter to edit the instruction at the current counter. When you enter "edit" mode, the Toy CPU shows `EDT` ("edit" mode) on the status lights.
+
+![Image of the toy CPU editing screen.][6]
+
+The Toy CPU has a cheat sheet that's "taped" to the front of the display. This lists the different opcodes the Toy CPU can process:
+
+- `00000000` (`STOP`): Stop program execution.
+- `00000001` (`RIGHT`): Shift the bits in the accumulator to the right by one position. The value 00000010 becomes 00000001, and 00000001 becomes 00000000.
+- `00000010` (`LEFT`): Shift the bits in the accumulator to the left by one position. The value 01000000 becomes 10000000, and 10000000 becomes 00000000.
+- `00001111` (`NOT`): Binary NOT the accumulator. For example, the value 10001000 becomes 01110111.
+- `00010001` (`AND`): Binary AND the accumulator with the value stored at an address. The address is stored in the next counter.
+- `00010010` (`OR`): Binary OR the accumulator with the value stored at an address.
+- `00010011` (`XOR`): Binary XOR (“exclusive or”) the accumulator with the value stored at an address.
+- `00010100` (`LOAD`): Load (copy) the value from an address into the accumulator.
+- `00010101` (`STORE`): Store (copy) the value in the accumulator into an address.
+- `00010110` (`ADD`): Add the value stored at an address to the accumulator.
+- `00010111` (`SUB`): Subtract the value stored at an address from the accumulator.
+- `00011000` (`GOTO`): Go to (jump to) a counter address.
+- `00011001` (`IFZERO`): If the accumulator is zero, go to (jump to) a counter address.
+- `10000000` (`NOP`): No operation; safely ignored.
+
+When in "edit" mode, use the left and right arrow keys to select a bit in the opcode, and press `Space`to flip the value between off (0) and on (1). When you are done editing, press `Enter`to go back to "input" mode.
+
+![Image of the toy CPU input mode screen.][7]
+
+### A sample program
+
+I want to explore the Toy CPU by entering a short program that adds two values, and stores the result in the Toy's memory. Effectively, this performs the arithmetic operation **A+B=C**. To create this program, you only need a few opcodes:
+
+- `00010100` (`LOAD`): Load (copy) the value from an address into the accumulator.
+- `00010110` (`ADD`): Add the value stored at an address to the accumulator.
+- `00010101` (`STORE`): Store (copy) the value in the accumulator into an address.
+- `00000000` (`STOP`): Stop program execution.
+
+The `LOAD`, `ADD`, and `STORE` instructions require a memory address, which will always be in the next counter location. For example, the first two instructions of the program are:
+
+```
+counter 0: 00010100
+counter 1: some memory address where the first value A is stored
+```
+
+The instruction in counter 0 is the `LOAD`operation, and the value in counter 1 is the memory address where you have stored some value. The two instructions together copy a value from memory into the Toy's accumulator, where you can work on the value.
+
+Having loaded a number **A** into the accumulator, you need to add the value **B** to it. You can do that with these two instructions:
+
+```
+counter 2: 00010110
+counter 3: a memory address where the second value B is stored
+```
+
+Say that you loaded the value 1 (**A**) into the accumulator, then added the value 3 (**B**) to it. The accumulator will now have the value 4. Now you need to copy the value 4 into another memory address (**C**) with these two instructions:
+
+```
+counter 4: 00010101
+counter 5: a memory address (C) where we can save the new value
+```
+
+Having added the two values together, you can now end the program with this instruction:
+
+```
+counter 6: 00000000
+```
+
+Any instructions after counter 6 are available for the program to use as stored memory. That means you can use the memory at counter 7 for the value **A**, the memory in counter 8 for the value **B**, and the memory at counter 9 for the stored value **C**. You need to enter these separately into the Toy:
+
+```
+counter 7: 00000001 (1)
+counter 8: 00000011 (3)
+counter 9: 00000000 (0, will be overwritten later)
+```
+
+Having figured out all the instructions and the memory locations for **A**, **B**, and **C**, you can now enter the full program into the Toy. This program adds the values 1 and 3 to get 4:
+
+```
+counter 0: 00010100
+counter 1: 00000111 (7)
+counter 2: 00010110
+counter 3: 00001000 (8)
+counter 4: 00010101
+counter 5: 00001001 (9)
+counter 6: 00000000
+counter 7: 00000001 (1)
+counter 8: 00000011 (3)
+counter 9: 00000000 (0, will be overwritten later)
+```
+
+To run the program, press the `R` key when in "input" mode. The Toy CPU will show `RUN` ("run" mode) in the status lights, and execute your program starting at counter 0.
+
+The Toy has a significant delay built into it, so you can watch the Toy execute each step in the program. You should see the counter move from 00000000 (0) to 00000110 (6) as the program progresses. After counter 1, the program loads the value 1 from memory location 7, and the accumulator updates to 00000001 (1). After counter 3, the program will add the value 3 and update the accumulator to show 00000100 (4). The accumulator will remain that way until the program stores the value into memory location 9 after counter 5 then ends at counter 6.
+
+![Image of the Toy in RUN mode.][8]
+
+### Exploring machine language programming
+
+You can use the Toy to create other programs and further explore machine language programming. Test your creativity by writing these programs in machine language.
+
+### A program to flash the lights on the accumulator
+
+Can you light up the right four bits on the accumulator, then the left four bits, then all of the bits? You can write this program in one of two ways:
+
+A straightforward approach would be to load three values from different memory addresses, like this:
+
+```
+counter 0: LOAD
+counter 1: "right"
+counter 2: LOAD
+counter 3: "left"
+counter 4: LOAD
+counter 5: "all"
+counter 6: STOP
+counter 7: 00001111 ("right")
+counter 8: 11110000 ("left")
+counter 9: 11111111 ("all")
+```
+
+Another way to write this program is to experiment with the NOT and OR binary operations. This results in a smaller program:
+
+```
+counter 0: LOAD
+counter 1: "right"
+counter 2: NOT
+counter 3: OR
+counter 4: "right"
+counter 5: STOP
+counter 6: 00001111 ("right")
+```
+
+### Count down from a number
+
+You can use the Toy as a countdown timer. This program exercises the IFZERO test, which will jump the program to a new counter only if the accumulator is zero:
+
+```
+counter 0: LOAD
+counter 1: "initial value"
+counter 2: IFZERO (this is also the "start" of the countdown)
+counter 3: "end"
+counter 4: SUB
+counter 5: "one"
+counter 6: GOTO
+counter 7: "start"
+counter 8: STOP
+counter 9: 00000111 ("initial value")
+counter 10: 00000001 ("one")
+```
+
+The Toy CPU is a great way to learn about machine language. I used the Toy CPU in my introductory course, and the students said they found it difficult to write the first program, but writing the next one was much easier. The students also commented that writing programs in this way was actually fun, and they learned a lot about how computers actually work. The Toy CPU is educational and fun!

+Why would you want to build a [DevOps][1] culture? There are many benefits to the streamlined collaboration of the development and operations teams. A major goal is efficiency: Increasing the speed of new software deployments and reducing idle time for workers. Fostering trust between colleagues can improve employee satisfaction, produce new innovations, and positively impact profitability.

+[DevOps][2] is a broad philosophy with a range of interpretations. In other words, you can visit 40 companies and find 40,000 different ideas about using DevOps effectively in the workplace. This diversity of opinion is actually a good thing–so many perspectives are useful for building stronger teams. This guide will look at the top tips for encouraging better collaboration between colleagues within a DevOps culture.
+
+Each section offers a different aspect of DevOps culture and looks at ways to introduce it into your workforce.
+
+![DevOps includes collaboration, workflow, infosec, and iteration.][3]
+
+### Continuous development of processes
+
+This core tenet of DevOps culture sets it apart from many other types of workplace ethos. The DevOps philosophy says that it is essential to make mistakes because it shows you are trying out new ideas.
+
+The heart of DevOps culture is a commitment to evolving creativity. Practically, that means not yelling at your direct reports when test results show that things were better before they changed it. It means recognizing that progress is not linear and success is never a straight line.
+
+DevOps expert [Gene Kim][4] advocates for risk-taking and experimentation. This implies letting your team work on unusual tasks to find new insights.
+
+Should your organization be profit-driven? Can you allow your teams to try something new? I'm talking about something other than unrelated passion projects. Continuous process development means being open to upgrading present methods. Great sales leaders appreciate that results matter more than presenteeism, so it is always crucial to focus on how teams are working rather than how much.
+
+### Readily give feedback and actively seek it
+
+Increased trust between individuals is another key feature of a thriving DevOps culture. Whether your staff is learning how to build affiliate network contacts or trying to design their next [UX][5] survey, everyone should be open to feedback on their work. But this will never happen until your teammates respect each other's opinions and trust that feedback is given in a spirit of good intention.
+
+This culture may sound impossible to cultivate; indeed, some companies will struggle to achieve this more than others. Granted, a large part of the success of giving and receiving feedback depends on the personalities of your employees. It is possible to screen for this during the recruitment process.
+
+Before you expect staff to readily offer feedback to colleagues and seek it in the first place, you should lead by example. Members of the C-suite should be modeling this behavior, openly asking members of the company to pose probing questions about their strategic decisions, and providing balanced feedback.
+
+![DevOps is the intersection of development, quality assurance, and operations][6]
+
+### Always look for improvements
+
+Building on increased intellectual trust between colleagues, your team should look for ways to improve its work. The nature of DevOps means the software development team will be producing deployments more rapidly than with traditional approaches.
+
+However, this culture of openness to improvement can positively impact departments beyond development and operations. Ask yourself what other areas of your business could do with a burst of optimism.
+
+Be on the lookout for training and upskilling opportunities. Even if a training course is less salient than advertised, the chance to network with industry professionals and build contacts for the future can only enhance the diversity of ideas within your organization.
+
+### Save ideas for later development
+
+Part of your DevOps toolchain should be a heavily used account on [Git][7]. You can use Git as a common repository for scripts produced during software development and other related projects. Known as "version control," Git allows programmers to save iterations of their work and reuse or improve the work of others.
+
+You're aiming for the ability to keep hold of good ideas for future use. A certain pathway did not work out for specific reasons. However, just because that set of ideas was wrong for the time it was conceived does not mean it can never become helpful in the future.
+
+As the entire focus of DevOps rests on end-to-end ownership of software in production, saving iterations of developments truly supports this principle. You want to see an improved focus on and commitment to the software testing project at hand.
+
+A simple way to incorporate this is to request that developers include ideas for future work in the developer contract and final project report. Make sure tech services managers know they should ask for examples of side-branching ideas that cropped up during the build. The more minds aware of these little innovations, the more likely someone will remember one when needed.
+
+### Sit close together (physically or virtually)
+
+The goal is to share a common understanding of one another's job roles and how they interrelate. You can achieve this in a few simple ways, summarized by three words: Sit close together. Invite other teams to your meetings and share user feedback reports in their entirety. Have lunch together, plan virtual happy hours together, and generally make sure your colleagues are in close proximity. About 90% of teams with a mature DevOps protocol report a clear understanding of their responsibilities to other teams compared to only about 46% of workers in immature DevOps teams.
+
+Although it can be tempting to form cliques with like-minded folk and only hang out with staff hired to carry out the same tasks as you, this is terrible for the business as a whole. Whether you like it or not, all humans are multi-faceted and capable of contributing their unique talents to a whole host of scenarios.
+
+The idea of closer collaboration is to honor the ability of anyone to suggest improvements to the products or work processes going on around them. If you only ever sit at a distance from the other departments within the company, you will miss countless opportunities to share intelligent ideas. After all, you often learn best in the free flow of ideas during a conversation.
+
+### Commit to automation
+
+You should be looking to automate mundane and repetitive tasks in the name of efficiency and process acceleration. Every industry has boring–and quite frankly, silly–exercises carried out daily or weekly.
+
+Whether this is manually copying data from one page to another or typing out audio transcripts by hand, staff at every level should insist that machines take on such burdens where possible. The reality is automation technology advances every single year, and operational processes should, too. [Automation testing][8] is so crucial to DevOps that it is the second principle of the CALMS framework (the "C" of which stands for "culture").
+
+How can you make this happen? Invite staff to openly express which aspects of their job they feel could be automated and then–here is the crucial part–support the facilities needed to automate them. That might mean a $600 annual subscription to a software program, a complete enterprise application modernization, or two days of developers' time to build a new tool to use in-house.
+
+Either way, you should assess the benefits of automation and consider how much time you could save for everyone. DevOps statistics continually indicate just how much better off modern companies are by integrating these beneficial principles year after year.
+
+### Explore new ways of working successfully
+
+A culture shift doesn't happen overnight. The sooner you start, though, the sooner you see results. In my experience, people embrace change when it's a genuine improvement on what has gone before. DevOps provides a framework for such improvements. Whether you're just getting started with DevOps in your organization or simply want to improve your existing culture, consider the above points and how they relate to your organization's future.

+
+Use time-series data to power your edge projects with open source tools
+======
+
+Gathering data as it changes over the passage of time is known as time-series data. Today, it has become a part of every industry and ecosystem. It is a large part of the growing IoT sector and will become a larger part of everyday people's lives. But time-series data and its requirements are hard to work with. This is because there are no tools that are purpose-built to work with time-series data. In this article, I go into detail about those problems and how InfluxData has been working to solve them for the past 10 years.
+
+### InfluxData
+
+InfluxData is an open source time-series database platform. You may know about the company through [InfluxDB][1], but you may not have known that it specialized in time-series databases. This is significant, because when managing time-series data, you deal with two issues — storage lifecycle and queries.
+
+When it comes to storage lifecycle, it's common for developers to initially collect and analyze highly detailed data. But developers want to store smaller, downsampled datasets that describe trends without taking up as much storage space.
+
+When querying a database, you don't want to query your data based on IDs. You want to query based on time ranges. One of the most common things to do with time-series data is to summarize it over a large period of time. This kind of query is slow when storing data in a typical relational database that uses rows and columns to describe the relationships of different data points. A database designed to process time-series data can handle queries exponentially faster. InfluxDB has its own built-in querying language: Flux. This is specifically built to query on time-series data sets.
+
+![Image of how Telegraf works.][2]
+
+### Data acquisition
+
+Data acquisition and data manipulation come out of the box with some awesome tools. InfluxData has over 12 client libraries that allow you to write and query data in the coding language of your choice. This is a great tool for custom use cases. The open source ingest agent, Telegraf, includes over 300 input and output plugins. If you're a developer, you can contribute your own plugin, as well.
+
+InfluxDB can also accept a CSV upload for small historical data sets, as well as batch imports for large data sets.
+
+```
+import math
+bicycles3 = from(bucket: "smartcity")
+ |> range(start:2021-03-01T00:00:00z, stop: 2021-04-01T00:00:00z)
+ |> filter(fn: (r) => r._measurement == "city_IoT")
+ |> filter(fn: (r) => r._field == "counter")
+ |> filter(fn: (r) => r.source == "bicycle")
+ |> filter(fn: (r) => r.neighborhood_id == "3")
+ |> aggregateWindow(every: 1h, fn: mean, createEmpty:false)
+bicycles4 = from(bucket: "smartcity")
+ |> range(start:2021-03-01T00:00:00z, stop: 2021-04-01T00:00:00z)
+ |> filter(fn: (r) => r._measurement == "city_IoT")
+ |> filter(fn: (r) => r._field == "counter")
+ |> filter(fn: (r) => r.source == "bicycle")
+ |> filter(fn: (r) => r.neighborhood_id == "4")
+ |> aggregateWindow(every: 1h, fn: mean, createEmpty:false)join(tables: {neighborhood_3: bicycles3, neighborhood_4: bicycles4}, on ["_time"], method: "inner")
+ |> keep(columns: ["_time", "_value_neighborhood_3","_value_neighborhood_4"])
+ |> map(fn: (r) => ({
+ r with
+ difference_value : math.abs(x: (r._value_neighborhood_3 - r._value_neighborhood_4))
+ }))
+```
+
+### Flux
+
+Flux is our internal querying language built from the ground up to handle time-series data. It's also the underlying powerhouse for a few of our tools, including tasks, alerts, and notifications. To dissect the flux query from above, you need to define a few things. For starters, a "bucket" is what we call a database. You configure your buckets and then add your data stream into them. The query calls the smartcity bucket, with the range of a specific day (a 24-hour period to be exact.) You can get all the data from the bucket, but most users include a data range. That's the most basic flux query you can do.
+
+Next, I add filters, which filter the data down to something more exact and manageable. For example, I filter for the count of bicycles in the neighborhood assigned to the id of 3. From there, I use aggregateWindow to get the mean for every hour. That means I expect to receive a table with 24 columns, one for every hour in the range. I do this exact same query for neighborhood 4 as well. Finally, I join the two tables and get the differences between bike usage in these two neighborhoods.
+
+This is great if you want to know what hours are high-traffic hours. Obviously, this is just a small example of the power of flux queries. But it gives a great example of some of the tools flux comes with. I also have a large amount of data analysis and statistics functions. But for that, I suggest checking out the Flux documentation.
+
+```
+import "influxdata/influxdb/tasks"
+option task = {name: PB_downsample, every: 1h, offset: 10s}
+from(bucket: "plantbuddy")
+ |>range(start: tasks.lastSuccess(orTime: -task.every))
+ |>filter(fn: (r) => r["_measurement"] == "sensor_data")
+ |>aggregateWindow(every: 10m, fn:last, createEmpty:false)
+ |>yield(name: "last")
+ |>to(bucket: "downsampled")
+```
+
+### Tasks
+
+An InfluxDB task is a scheduled Flux script that takes a stream of input data and modifies or analyzes it in some way. It then stores the modified data in a new bucket or performs other actions. Storing a smaller data set into a new bucket is called "downsampling," and it's a core feature of the database, and a core part of the time-series data lifecycle.
+
+You can see in the current task example that I've downsampled the data. I'm getting the last value for every 10-minute increment and storing that value in the downsampled bucket. The original data set might have had thousands of data points in those 10 minutes, but now the downsampled bucket only has 60 new values. One thing to note is that I'm also using the last success function in range. This tells InfluxDB to run this task from the last time it ran successfully, just in case it has failed for the past 2 hours, in which case it can go back three hours in time to the last successful run. This is great for built-in error handling.
+
+![Image of the checks and alerts notification system.][3]
+
+### Checks and alerts
+
+InfluxDB includes an alerting or checks and notification system. This system is very straightforward. You start with a check that looks at the data periodically for anomalies that you've defined. Normally, this is defined with thresholds. For example, any temperature value under 32° F gets assigned a value of `WARN`, and anything above 32° F gets assigned a value of `OK`, and anything below 0° F gets a value of `CRITICAL`. From there, your check can run as often as you deem necessary. There is a recorded history of your checks and the current status of each. You are not required to set up a notification when it's not needed. You can just reference your alert history as needed.
+
+Many people choose to set up their notifications. For that, you need to define a notification endpoint. For example, a chat application could make an HTTP call to receive your notifications. Then you define when you would like to receive notifications, for example you can have checks run every hour. You can run notifications every 24 hours. You can have your notification respond to a change in the value, for example `WARN` to `CRITICAL`, or when a value is `CRITICAL`, regardless of it changing from `OK` to `WARN`. This is a highly customizable system. The Flux code that's created from this system can also be edited.
+
+![Image of the new Edge feature.][4]
+
+### Edge
+
+To wrap up, I'd like to bring all the core features together, including a very special new feature that's recently been released. Edge to cloud is a very powerful tool that allows you to run the open source InfluxDB and locally store your data in case of connectivity issues. When connectivity is repaired, it streams the data to the InfluxData cloud platform.
+
+This is significant for edge devices and important data where any loss of data is detrimental. You define that you want a bucket to be replicated to the cloud, and then that bucket has a disk-backed queue to store the data locally. Then you define what your cloud bucket should replicate into. The data is stored locally until connected to the cloud.
+
+### InfluxDB and the IoT Edge
+
+Suppose you have a project where you want to [monitor the health of household plants][5] using IoT sensors attached to the plant. The project is set up using your laptop as the edge device. When your laptop is closed or otherwise off, it stores the data locally, and then streams it to my cloud bucket when reconnected.
+
+![Image showing how Plant buddy works.][6]
+
+One thing to notice is that this downsamples data on the local device before storing it in the replication bucket. Your plant's sensors provide a data point for every second. But it condenses the data to be an average of one minute so you have less data to store. In the cloud account, you might add some alerts and notifications that let you know when the plant's moisture is below a certain level and needs to be watered. There could also be visuals you could use on a website to tell users about their plants' health.
+
+Databases are the backbone of many applications. Working with time-stamped data in a time series database platform like InfluxDB saves developers time, and gives them access to a wide range of tools and services. The maintainers of InfluxDB love seeing what people are building within our open source community, so connect with us and share your projects and code with others!

+
+Use this open source API gateway to scale your API
+======
+
+An API gateway is a single point of entry for incoming calls to an [application programming interface (API)][1]. The gateway aggregates the services being requested and then returns the appropriate response. To make your API gateway effective, it's vital for you to design a reliable, efficient, and simple API. This is an architectural puzzle, but it's one you can solve as long as you understand the most important components.
+
+### API-Led approach
+
+An API-Led approach puts an API at the heart of communication between applications and the business capabilities they need to access in order to consistently deliver seamless functionality across all digital channels. **API-Led connectivity** refers to the technique of using a reusable and well-designed API to link data and applications.
+
+### API-Led architecture
+
+API-Led architecture is an architectural approach that looks at the best ways of reusing an API. API-Led architecture addresses things like:
+
+- Protecting an API from unauthorized access.
+- Ensuring that consuming applications can always find the right API endpoint.
+- Throttling or limiting the number of calls made to an API to ensure continuous availability.
+- Supporting continuous integration, testing, lifecycle management, monitoring, operations, and so on.
+- Preventing error propagation across the stack.
+- Real-time monitoring of an API with rich analytics and insight.
+- Implementing scalable and flexible business capabilities (for example, supporting a [microservice][2] architecture.)
+
+### API resource routing
+
+Implementing an API gateway as the single entry point to all services means that API consumers only have to be aware of one URL. It becomes the API gateway's responsibility to route traffic to the corresponding service endpoints, and to enforce policies.
+
+![Image depicting the API routing traffic.][3]
+
+This reduces complexity on the API consumer side because the client applications don't need to consume functionality from multiple HTTP endpoints. There's alsono need to implement a separate layer for authentication, authorization, throttling, and rate limiting for each service. Most API gateways, like the open source [Apache APISIX][4] project, already have these core features built in.
+
+### API content-based routing
+
+A content-based routing mechanism also uses an API gateway to route calls based on the content of a request. For example, a request might be routed based on the HTTP header or message body instead of just its target URI.
+
+Consider a scenario when database sharding is applied in order to distribute the load across multiple database instances. This technique is typically applied when the overall number of records stored is huge and a single instance struggles to manage the load.
+
+A better solution is to spread records across multiple database instances. Then you implement multiple services, one for each unique datastore, and adopt an API gateway as the only entry point to all services. You can then configure your API gateway to route calls to the corresponding service based on a key obtained either from the HTTP header or the payload.
+
+![Image of the API gateway exposing a single customer.][5]
+
+In the above diagram, an API gateway is exposing a single `/customers` resource for multiple customer services, each with a different data store.
+
+### API geo-routing
+
+An API geo-routing solution routes an API call to the nearest API gateway based on its origin. In order to prevent latency issues due to distance (for example, a consuming application from Asia calling an API located in North America), you can deploy an API gateway in multiple regions across the world. You can use a different subdomain for each API gateway in each region, letting the consuming application determine the nearest gateway based on application logic. Then, an API gateway provides internal load balancing to make sure that incoming requests are distributed across available instances.
+
+![Image of a DNS traffic management system.][6]
+
+It's common to use a DNS traffic management service and an API gateway to resolve each subdomain against the region's load balancer to target the nearest gateway.
+
+### API aggregator
+
+This technique performs operations (for example, queries) against multiple services, and returns the result to the client service with a single HTTP response. Instead of having a client application make several calls to multiple APIs, an API aggregator uses an API gateway to do this on behalf of the consumer on the server side.
+
+Suppose you have a mobile app that makes multiple calls to different APIs. This increases complexity in the client-side code, it causes over-utilization of network resources, and produces a poor user experience due to increased latency. An API gateway can accept all information required as input, and can request authentication and validation, and understand the data structures from each API it interacts with. It's also capable of transforming the response payloads so they can be sent back to the mobile app as a uniform payload needed for the consumer.
+
+![Image of an API gateway.][7]
+
+### API centralized authentication
+
+In this design, an API gateway acts as a centralized authentication gateway. As an authenticator, an API gateway looks for access credentials in the HTTP header (such as a bearer token.) It then implements business logic that validates those credentials with an identity provider.
+
+![Image of a tree showing API gateway's centralized authentication.][8]
+
+Centralized authentication with an API gateway can solve many problems. It completely offloads user management from an application, improving performance by responding quickly to authentication requests received from client applications. Apache APISIX offers a [variety of plugins][9] to enable different methods of API gateway authentication.
+
+![Image showing Apache ASPISIS and various plugins.][10]
+
+### API format conversion
+
+API format conversion is the ability to convert payloads from one format to another over the same transport. For example, you can transfer from XML/SOAP over HTTPS to JSON over HTTPS, and back again. An API gateway offers capabilities in support of a [REST API][11] and can do payload conversions and transport conversions. For instance, a gateway can convert from a message queue telemetry transport (MQTT) over TCP (a very popular transport in IoT) to JSON over HTTPS.
+
+![Image depicting APISIX transfers.][12]
+
+Apache APISIX is able to receive an HTTP request, transcode it, and then forward it to a gRPC service. It gets the response and returns it back to the client in HTTP format by means of its [gRPC Transcode][13] plug-in.
+
+### API observability
+
+By now, you know that an API gateway offers a central control point for incoming traffic to a variety of destinations. But it can also be a central point for observation, because it's uniquely qualified to monitor all traffic moving between the client and service networks. You can adjust an API gateway so that the data (structured logs, metrics, and traces) can be collected for use with specialized monitoring tools**.**
+
+Apache APISIX provides [pre-built connectors][14] so you can integrate with external monitoring tools. You can leverage these connectors to collect log data from your API gateway to further derive useful metrics and gain complete visibility into how your services are being used. You can also manage the performance and security of your API in your environment.
+
+### API caching
+
+API caching is usually implemented inside the API gateway. It can reduce the number of calls made to your endpoint, and also improve the latency of requests to your API by caching a response from upstream. If the API gateway cache has a fresh copy of the requested resource, it uses that copy to satisfy the request directly instead of making a request to the endpoint. If the cached data is not found, the request travels to the intended upstream services.
+
+![Image depicting how the API gateway cache functions.][15]
+
+### API fault handling
+
+API services may fail due to any number of reasons. In such scenarios, your API service must be resilient enough to deal with predictable failures. You also want to ensure that any resilience mechanisms you have in place work properly. This includes error handling code, circuit breakers, health checks, fallbacks, redundancy, and so on. Modern API gateways support all the most common error-handling features, including automatic retries and timeouts.
+
+![Image depicting some of the many mechanisms that the modern API Gatway can support.][16]
+
+An API gateway acts as an orchestrator that can use a status report to decide how to manage traffic, send load balances to a healthy node, and can fail fast. It can also alert you when something goes wrong. An API gateway also ensures that routing and other network-level components work together successfully to deliver a request to the API process. It helps you detect a problem in the early stage, and to fix issues. A fault injection mechanism (like the one Apache APISIX uses) at the API gateway level can be used to test the resiliency of an application or microservices API against various forms of failures.
+
+### API versioning
+
+This refers to having the ability to define and run multiple concurrent versions of an API. This is particularly important, because an API evolves over time. Having the ability to manage concurrent versions of an API enables API consumers to incrementally switch to newer versions of an API. This means older versions can be deprecated and ultimately retired. This is important because an API, just like any other software application, should be able to evolve either in support of new features or in response to bug fixes.
+
+![Image of using the API Gateway to implement API versioning.][17]
+
+You can use an API gateway to implement API versioning. The versioning can be a header, query parameter, or path.
+
+### Gateway to APISIX
+
+If you want to scale your API services, you need an API gateway. The Apache APISIX project provides essential features for a robust entrypoint, and its benefits are clear. It aligns with an API-Led architecture, and is likely to transform the way your clients interact with your hosted services.

+How to use methods in Java
+======
+
+A method in Java (called a "function" in many other programming languages) is a portion of code that's been grouped together and labeled for reuse. Methods are useful because they allow you to perform the same action or series of actions without rewriting the same code, which not only means less work for you, it means less code to maintain and debug when something goes wrong.
+
+A method exists within a class, so the standard Java boilerplate code applies:
+
+```
+package com.opensource.example;
+
+public class Example {
+ // code here
+}
+```
+
+A package definition isn't strictly necessary in a simple one-file application like this, but it's a good habit to get into, and most IDEs enforce it.
+
+By default, Java looks for a `main` method to run in a class. Methods can be made public or private, and static or non-static, but the main method must be public and static for the Java compiler to recognize and utilize it. When a method is public, it's able to be executed from outside the class. To call the `Example` class upon start of the program, its `main` method must be accessible, so set it to `public`.
+
+Here's a simple demonstration of two methods: one `main` method that gets executed by default when the `Example` class is invoked, and one `report` method that accepts input from `main` and performs a simple action.
+
+To mimic arbitrary data input, I use an if-then statement that chooses between two strings, based on when you happen to start the application. In other words, the `main` method first sets up some data (in real life, this data could be from user input, or from some other method elsewhere in the application), and then "calls" the `report` method, providing the processed data as input:
+
+```
+package com.opensource.example;
+
+public class Example {
+ public static void main(String[] args) {
+ // generate some data
+ long myTime = System.currentTimeMillis();
+ String weather;
+
+ if ( myTime%2 == 0 ) {
+ weather = "party";
+ } else {
+ weather = "apocalypse";
+ }
+
+ // call the other method
+ report(weather);
+ }
+
+ private static void report(String day) {
+ System.out.printf("Welcome to the zombie %s\n", day);
+ }
+}
+```
+
+Run the code:
+
+```
+$ java ./Example.java
+Welcome to the zombie apocalypse
+$ java ./Example.java
+Welcome to the zombie party
+```
+
+Notice that there are two different results from the same `report` method. In this simple demonstration, of course, there's no need for a second method. The same result could have been generated from the if-then statement that mimics the data generation. But when a method performs a complex task, like resizing an image into a thumbnail and then generating a widget on screen using that resized image, then the "expense" of an additional component makes a lot of sense.
+
+### When to use a Java method
+
+It can be difficult to know when to use a method and when to just send data into a [Java Stream][1] or loop. If you're faced with that decision, the answer is usually to use a method. Here's why:
+
+- Methods are cheap. They don't add processing overhead to your code.
+- Methods reduce the line count of your code.
+- Methods are specific. It's usually easier to find a method called `resizeImage` than it is to find code that's hidden in a loop somewhere in the function that loads images from the drive.
+- Methods are reusable. When you first write a method, you may _think_ it's only useful for one task within your application. As your application grows, however, you may find yourself using a method you thought you were "done" with.
+
+### Functional vs. object-oriented programming
+
+Functional programming utilizes methods as the primary construct for performing tasks. You create a method that accepts one kind of data, processes that data, and outputs new data. String lots of methods together, and you have a dynamic and capable application. Programming languages like C and [Lua][2] are examples of this style of coding.
+
+The other way to think of accomplishing tasks with code is the object-oriented model, which Java uses. In object-oriented programming, methods are components of a template. Instead of sending data from method to method, you create objects with the option to alter them through the use of their methods.
+
+Here's the same simple zombie apocalypse demo program from an object-oriented perspective. In the functional approach, I used one method to generate data and another to perform an action with that data. The object-oriented equivalent is to have a class that represents a work unit. This example application presents a message-of-the-day to the user, announcing that the day brings either a zombie party or a zombie apocalypse. It makes sense to program a "day" object, and then to query that day to learn about its characteristics. As an excuse to demonstrate different aspects of object-oriented construction, the new sample application will also count how many zombies have shown up to the party (or apocalypse).
+
+Java uses one file for each class, so the first file to create is `Day.java`, which serves as the Day object:
+
+```
+package com.opensource.example;
+
+import java.util.Random;
+
+// Class
+public class Day {
+ public static String weather;
+ public int count;
+
+// Constructor
+ public Day() {
+ long myTime = System.currentTimeMillis();
+
+ if ( myTime%2 == 0 ) {
+ weather = "paradise";
+ } else {
+ weather = "apocalypse";
+ }
+ }
+
+// Methods
+ public String report() {
+ return weather;
+ }
+
+ public int counter() {
+ Random rand = new Random();
+ count = count + rand.nextInt(100);
+
+ return(count);
+ }
+}
+```
+
+In the `Class` section, two fields are created: `weather` and `count`. Weather is static. Over the course of a day (in this imaginary situation), weather doesn't change. It's either a party or an apocalypse, and it lasts all day. The number of zombies, however, increases over the course of a day.
+
+In the `Constructor` section, the day's weather is determined. It's done as a [constructor][3] because it's meant to only happen once, when the class is initially invoked.
+
+In the `Methods` section, the `report` method only returns the weather report as determined and set by the constructor. The `counter` method, however, generates a random number and adds it to the current zombie count.
+
+This class, in other words, does three very different things:
+
+- Represents a "day" as defined by the application.
+- Sets an unchanging weather report for the day.
+- Sets an ever-increasing zombie count for the day.
+
+To put all of this to use, create a second file:
+
+```
+package com.opensource.example;
+
+public class Example {
+ public static void main(String[] args) {
+ Day myDay = new Day();
+ String foo = myDay.report();
+ String bar = myDay.report();
+
+ System.out.printf("Welcome to a zombie %s\n", foo);
+ System.out.printf("Welcome to a zombie %s\n", bar);
+ System.out.printf("There are %d zombies out today.\n", myDay.counter());
+ System.out.printf("UPDATE: %d zombies. ", myDay.counter());
+ System.out.printf("UPDATE: %d zombies. ", myDay.counter());
+ }
+}
+```
+
+Because there are now two files, it's easiest to use a Java IDE to run the code, but if you don't want to use an IDE, you can create your own [JAR file][4]. Run the code to see the results:
+
+```
+Welcome to a zombie apocalypse
+Welcome to a zombie apocalypse
+There are 35 zombies out today.
+UPDATE: 67 zombies. UPDATE: 149 zombies.
+```
+
+The "weather" stays the same regardless of how many times the `report` method is called, but the number of zombies on the loose increases the more you call the `counter` method.
+
+### Java methods
+
+Methods (or functions) are important constructs in programming. In Java, you can use them either as part of a single class for functional-style coding, or you can use them across classes for object-oriented code. Both styles of coding are different perspectives on solving the same problem, so there's no right or wrong decision. Through trial and error, and after a little experience, you learn which one suits a particular problem best.

+Wordbook: Offline English Dictionary App for GNOME
+======
+
+**Meet Wordbook – an offline dictionary application for the GNOME desktop.**
+
+We mostly search Google, DDG or any search engine online for word information such as meaning, synonyms, antonyms etc.
+
+Since almost everyone today has an internet-connected mobile phone, it’s probably easier to search on Google.
+
+But for offline usage, you may try [Wordbook][1] when no internet connection is available.
+
+### Wordbook: Offline dictionary app
+
+The app is very basic in nature. But does its job with its capacity. Wordbook currently supports an English-to-English dictionary. At its core, it uses the [Open English WordNet database][2] for definitions. The Open English Wordnet is an open-source fork of the [Princeton Wordnet project][3].
+
+The Wordbook app can also pronounce words using [eSpeak][4] – a free and open-source speech synthesizer.
+
+![Wordbook - English to English Dictionary App][5]
+
+However, during the first run, it requires one-time internet access to download offline data. And that’s about it. Other notable feature includes live search, double-click search and custom definitions with HTML markup.
+
+Wordbook is a [GNOME app][6], built using the modern GTK4 and libadwaita. Hence integrates well with the GNOME desktop with light and dark themes. You can also use Wordbook’s random word feature to learn new words to increase your vocabulary.
+
+### Installation
+
+You can easily install it as a Flatpak app from Flathub. Set up your system for Flatpak & Flathub and then install it using the below command from the terminal:
+
+```
+flatpak install com.github.fushinari.Wordbook
+```
+
+After installation, you can find it on the application menu.
+
+### Close notes
+
+I hope you use this tiny app for your school or business work. The offline nature is handy if you are writing essays and longer paragraphs.
+
+Do you know any other offline dictionary for Linux? Let us know in the comment box.

+Install Ubuntu on Windows Using VirtualBox [Complete Guide]
+======
+
+**This tutorial will guide you through the easiest steps to install an Ubuntu desktop on Windows using Oracle VirtualBox.**
+
+[VirtualBox][1] is a popular virtualization software by Oracle which is available for Linux, mac and Windows systems. It is flexible and brings many features to take advantage of your virtualization. It’s the best and easy way to experience Ubuntu in Windows without installing it. However, I strongly recommend installing Ubuntu physically as a dual-boot to enjoy its advantage.
+
+The steps outlined below assume that you are installing Ubuntu for the first time in Windows. Hence the steps are a little descriptive and a bit lengthy. Furthermore, the following steps should work for Windows 10 and Windows 11 as host machines.
+
+### Contents
+
+- [Pre-requisite][2]
+- [Download Ubuntu ISO and VirtualBox set-up files][3]
+- [Install VirtualBox on Windows (Host)][4]
+- [Install Ubuntu (Guest) on VirtualBox][5]
+- [Guest addition installation and tips][6]
+
+### What you’ll need
+
+- A PC with internet access
+- Ubuntu Linux ISO image file for installation
+- Windows system with VirtualBox installed
+
+### Install Ubuntu on Windows Using VirtualBox
+
+#### Download and install the necessary items
+
+- Download the Ubuntu Linux desktop ISO image file from the following link.
+
+[Download Ubuntu Desktop][7]
+
+- Also, download the Oracle VirtualBox installer from the official website below.
+
+[Download VirtualBox][8]
+
+![Download location for VirtualBox for Windows][9]
+
+#### How to install and configure VirtualBox
+
+VirtualBox in Windows requires Microsoft Visual C++ 2019 Redistributable package. And you have to install it first. Download the package (under X64 architecture) from the below link:
+
+[Download][10]
+
+![Download the dependency for VirtualBox][11]
+
+![Install the dependency for VirtualBox][12]
+
+- After the above installation is complete, download the latest Python package from the below link. Python bindings are also a dependency for VirtualBox installation on Windows.
+
+[Download Python for Windows][13]
+
+- Then, launch the VirtualBox installation and follow the onscreen instructions to install it.
+- After installation, restart your Windows system again.
+
+#### Set up a virtual machine for Ubuntu
+
+- Launch VirtualBox from the start menu.
+
+![Select VirtualBox from start menu][14]
+
+- On the VirtualBox window toolbar, click **New**.
+- On the **Create VirtualBox** window, give the name of your virtual machine. It can be any name which identifies this version of Ubuntu.
+- Keep the **Folder Name** unchanged. This is the path where the virtual machine file will be created.
+- In the ISO Image field, browse the Ubuntu ISO file you downloaded.
+- And select the Unattended installation. If you un-select this, a [default user id (vboxuser) and password][15] will be created in your virtual machine. Let’s not follow it for now.
+
+![Click on New][16]
+
+![Select the ISO file][17]
+
+- Click on Hardware and select the RAM you want for your virtual box. A thumb rule is that your VM’s RAM size should be less than your physical RAM in the host system. I would recommend using 2 GB to 4 GB for a virtual machine for an 8 GB RAM system. For 4 GB RAM, use the slider (or type in) to make it 4096 MB (i.e. 4*1024).
+- Choose processor as 2 or 4.
+- Click on the Hard Disk section, and keep the file location unchanged.
+- Give a minimum of 20GB to 25GB for Ubuntu installation.
+- The hard disk file type value keeps as VDI (VirtualBox Disk Image)
+- Do not select the pre-allocate full size.
+- And finally, click on Finish.
+
+![Select Hardware][18]
+
+![Select Hard Disk][19]
+
+- You should see a new entry at the left panel of VirtualBox with an Ubuntu 22.04 entry (the name which you gave above).
+- Select the entry and click on Start to boot into the virtual machine
+
+![Boot Ubuntu in VirtualBox][20]
+
+#### Install Ubuntu using VirtualBox
+
+- After a successful boot, you should see the following screen, which shows various options for installing Ubuntu. Select **Try or install Ubuntu**.
+- In the Welcome screen, click on **Try Ubuntu**. And after a few moments, you should see the following Ubuntu LIVE desktop. If you want to change the resolution, right-click on the desktop and select Display settings. And change the resolution to 1400×900.
+- On the desktop, double-click on “**Install Ubuntu**…”.
+
+![Select Try Ubuntu][21]
+
+![Ubuntu LIVE desktop][22]
+
+- In the next set of screens, select Language and Keyboard Layout as your needs.
+- The Install screen provides you with the type of installation you need. Select Normal Installation, and select both options under Other options.
+- Since you are installing in the virtual disk space, i.e. which is just a file, you can safely choose the “Erase disk and install Ubuntu” option.
+- Hit Install Now and Continue.
+
+![Select Language][23]
+
+![Select Keybaord Layout][24]
+
+![Select install options][25]
+
+![Installation Type][26]
+
+![Write changes to disk][27]
+
+- Then select region, add name, user and password. This will be your user id and password to log on to Ubuntu after installation.
+- Hit continue to start the installation. Wait until it finishes.
+
+![User account creation][28]
+
+![Ubuntu Installation is complete][29]
+
+Click on Restart Now after the installation is complete. Wait for a few seconds and you should see a login screen. Use the user id and password to log in. And you should see Ubuntu desktop is running inside VirtualBox as VM in Windows.
+
+![Log on to Ubuntu][30]
+
+![Ubuntu running in Windows using Virtualbox][31]
+
+### Post-install configuration and tips (optional)
+
+#### Install Guest Additions
+
+After the successful installation, you should install the **VirtualBox guest additions** for Windows Host and Ubuntu Guest. The guest addition is a set of packages you need to install inside the guest VM (i.e. Ubuntu) to enable **shared folders, bi-directional copy/paste, automatic resolution change,** and many such features.
+
+To install it, boot into Ubuntu. From the VirtualBox menu, select `Devices > Insert Guest Additions CD Image`. The necessary packages will be mounted inside Ubuntu.
+
+![Select Guest addition from the menu][32]
+
+Open the file manager and open the mounted folder as shown below. And then right-click > select `open in terminal`.
+
+Then run the following command:
+
+```
+sudo ./VBoxLinuxAdditions.run
+```
+
+![Open the mounted disc and select option with terminal][33]
+
+![VirtualBox guest addition install for Windows host][34]
+
+After the above command is complete, restart Ubuntu VM.
+
+#### Enable Copy and paste between Windows and Ubuntu
+
+- To enable the copy and paste between Windows and Ubuntu systems, select `Devices > Shared Clipboard > Bi-directional` from the menu.
+
+![Enable clipboard sharing][35]
+
+#### Shutting down Ubuntu VM
+
+- Ideally, you should shut down a VM from its own power off menu. However, you can also shut down from the main VirtualBox window. Right-click on the VM name and select `Close > Poweroff`.
+
+![Poweroff Virtual machine][36]
+
+#### How to delete Ubuntu and remove all data
+
+- If you want to delete the Virtual machine entirely (.e.g. Ubuntu) and its data, select `Remove` and `delete all files`.
+
+![Select remove to delete a VM][37]
+
+![Select the delete options][38]
+
+### Close notes
+
+In this tutorial, you learned the easiest way to install Ubuntu on Windows (10 or 11) using VirtualBox. Also, you learned several post-install basic steps to configure the Ubuntu VM. You can use the above steps for any other Linux distributions in VirtualBox.
+
+Feel free to comment below if you have any problems or questions.

+How to Install Python on Windows [Beginner’s Guide]
+======
+
+**This simple guide demonstrates how to download and install Python on Windows.**
+
+This article is tested with the latest Python 3.11 stable version.
+
+Before you learn how to install Python on Windows, you might want to check how you can [install it easily][1] on Linux distributions such as Ubuntu. It’s better to try Python in Linux if you are planning to be a developer. That being said, you might want to check [how to install Linux (such as Ubuntu) alongside Windows][2].
+
+Python is a popular general-purpose programming language which becomes the developer’s choice in the past decade. And its popularity is increasing every day. it is widely used for web development, complex systems, data science, machine learning and all areas of science.
+
+There are two versions of Python that you may come across. Python2 is currently out of support. And the Python3 series is the ongoing support release.
+
+### Check whether Python is installed
+
+Before you install it on Windows, you should check whether it is already installed. In general, it should not be installed, unlike in Ubuntu (and other Linux distributions), where Python comes pre-installed.
+
+From the start menu, open “command prompt”.
+
+And type the following:
+
+```
+python --version
+```
+
+If Python is available, it will show you a message with the version details.
+
+### Download and Install Python
+
+Open the below official Python download page.
+
+[Download Python][3]
+
+![How to locate Python set up][4]
+
+At the top, you should see the current stable version. Click on the download link. If you are looking for any specific version, scroll down on this page and download the specific version under the label “Python releases by version number:”.
+
+After downloading, go to the Downloads folder and run the setup.
+
+Follow the on-screen instructions to install it.
+
+![Install Python step 1][5]
+
+![Install Python step 2][6]
+
+After installation is complete, verify the Python version.
+
+### Verify Python Version
+
+From the start menu, open “command prompt” and run the following command.
+
+```
+python --version
+```
+
+![Python version on Windows][7]
+
+You should see your system’s currently installed version of the Python package. Alternatively, you can also run below to get a Python interactive shell.
+
+```
+python
+```
+
+You can exit the shell using CTRL+Z and Enter.
+
+### Check PATH Variables
+
+You should check the system variable PATH with the Python executable location. This should be updated automatically using the installer.
+
+From the start menu, search “system variables” and open it.
+
+![Open Environment variable Settings][8]
+
+In the System Properties Dialog, click on `Advanced > Environment Variables`. Under the user variables section against the Path variable, check whether the Python installed location is present. Refer to the below image for a guideline.
+
+If you see all the path is present, you are all set to run your Python project.
+
+![Check Python Environment PATH Values in Windows][9]
+
+### Create and run your first Python program
+
+For an additional step, here’s how you can code & run your first Python program. You should ideally use any [recommended Python editor][10] to write your program.
+
+Here’s a simple program which outputs the text “debugpoint.com” in the console.
+
+```
+# Sample Python program
+print("debugpoint.com")
+```
+
+Save the file with any name. Here I have saved it as “hello.py” in E drive. The .py is the extension of Python source codes.
+
+To run this program, open a command prompt and execute below inside E drive.
+
+```
+python hello.py
+```
+
+**Output:**
+
+![Running a simple Python program in Windows][11]
+
+### Closing Notes
+
+I hope this simple beginner’s guide helps you to install Python in Windows, verify the installation and run your first program.
+
+Please let me know if you run into issues in the comment box below.

+Share Folder Between Guest and Host in virt-manager (KVM/Qemu/libvirt)
+======
+
+**In this guide, you will learn how to share a folder between host and guest in virt-manager using KVM, QEMU and libvirt.**
+
+The [virt-manager][1] application or package uses the [libvirt][2] library to provide virtual machine management services. It has a desktop interface that helps to create, delete, and manage multiple virtual machines.
+
+The virt-manager desktop interface and its components provide flexible virtual machine management services for various personal and business use cases. it is a free and open-source application primarily used for KVM virtual machines. However, it can also support other hypervisors such as Xen and LXC.
+
+In the earlier article, I explained [how to create a virtual machine using virt-manager][3]. This article covers how you can seamlessly access files and folders between guest and host virtual machines.
+
+### A note about virtiofs
+
+The sharing files and folders are powered by the libvirt shared file system called virtiofs. It provides all the features and parameters to access the directory tree on the host machine. Since most of the virt-manager virtual machine configurations are translated to XML, the share files/folders can also be specified by the XML file.
+
+### Share folder in virt-manager
+
+- First, make sure your guest virtual machine is powered off. From the virt-manager GUI, select the virtual machine and click on Open to pull up the console settings.
+
+![Open the settings][4]
+
+- Click on the icon which says show virtual hardware details in the toolbar. And then click on **Memory** on the left panel.
+- Select the option “**Enable shared memory**“. Click Apply.
+
+![Enable the shared memory option][5]
+
+- And then click “Add hardware” at the bottom.
+
+![Click on add hardware][6]
+
+- Select **File system** from the left panel in the add new hardware window.
+- Then select **Driver=virtiofs** in the details tab. Click on `browse > browse local` and **select the host path** you want to access inside the guest VM.
+- In the target path, mention any name you want. It’s just a file tag which will be used during mount.
+- So, if I want to access the Pictures/Screenshots folder (`/home/debugpoint/Pictures/Screenshots`), sample settings could be the following:
+
+![Add a new file system hardware][7]
+
+The XML settings are below for the above configuration. You can find it in the XML tab.
+
+```
+
+
+
+
+
+
+
+
+```
+
+Click on Finish. In the main virt-manager window, right-click on the VM and click Run to start the virtual machine. Make sure to click on the “show the graphical console” (monitor icon in the toolbar – if the VM is not showing.
+
+In the guest machine, create a folder where you want to mount the host folder. For this example, I have used /mnt/pictures.
+
+```
+sudo mkdir /mnt/pictures
+```
+
+And finally, mount the host folder using the tag you created in the above step to this new folder. Use the following command to do that from the terminal. Ensure to change the tag and folder name in the below command as your system.
+
+```
+sudo mount -t virtiofs mount_tag_pictures /mnt/pictures
+```
+
+Now you can browse the folders and add/delete items seamlessly in virt-manager between host and guest.
+
+![Access host files from virt-manager guest][8]
+
+### Wrapping Up
+
+I hope this solution helps you to access host files and folders from the guest machine. Remember, your user Id, which is used to launch the virt-manager app, should have the same access to the host folder.
+
+If you run into any errors, the above guide helped you drop a note below.

+
+A 4-minute guide to Java loops
+======
+
+A while loop performs a set of tasks for as long as some predefined condition is true. This is considered a control structure that directs the flow of a program. It's a way for you to tell your code what to do by defining a condition that it can test, and take action based on what it finds. The two kinds of while loops in Java are while and do while.
+
+### Java while loop
+
+A while loop is meant to iterate over data until some condition is satisfied. To create a while loop, you provide a condition that can be tested, followed by the code you want to run. Java has several built-in test functions, the simplest of which are mathematical operators (`<`, `>`, `==`, and so on):
+
+```
+package com.opensource.example;
+
+public class Example {
+ public static void main(String[] args) {
+
+ int count = 0;
+ while (count < 5) {
+ System.out.printf("%d ", count);
+ count++;
+ }
+ }
+}
+```
+
+In this simple example, the condition is that the variable `count` is less than 5. Because `count` is instantiated at 0, and then incremented by 1 in the code within the while loop, the program iterates a total of 5 times:
+
+```
+$ java ./while.java
+0 1 2 3 4
+```
+
+Before it can iterate a sixth time, the condition is no longer true, so the loop ends.
+
+The conditional statement for a while loop is vital. Getting it wrong could mean that your loop never executes. For instance, suppose you had set `count == 5` as the condition:
+
+```
+while (count == 5) {
+ System.out.printf("%d ", count);
+ count++;
+```
+
+When you run the code, it builds and runs successfully, but nothing happens:
+
+```
+$ java ./while.java
+$
+```
+
+The loop has been skipped because `count` was set to 0, and it's still 0 at the moment the while loop is first encountered. The loop never has a reason to start and `count` is never incremented.
+
+The reverse of this is when a condition starts as true and can never be false, this results in an infinite loop.
+
+### Java do while loop
+
+Similar to the while loop, a do while loop tests for the conditional at the end, not the beginning, of each iteration. With this, the code in your loop runs at least once because there's no gateway to entry, only a gateway to exit:
+
+```
+package com.opensource.example;
+
+public class Example {
+ public static void main(String[] args) {
+
+ int count = 9;
+ do {
+ System.out.printf("%d ", count);
+ count++;
+ } while(count == 5);
+ }
+}
+```
+
+In this sample code, `count` is set to 9. The condition for the loop to repeat is that `count` is equal to 5. But 9 isn't equal to 5. That check isn't performed until the end of the first iteration, though:
+
+```
+$ java ./do.java
+9
+```
+
+### Java infinite loops
+
+An infinite loop, as its name suggests, never ends. Sometimes they're created by mistake, but an infinite loop does have a valid use case. Sometimes you want a process to continue indefinitely (that's functionally infinite because you can't guarantee when you need it to stop), and so you might set your condition to something impossible to meet.
+
+Suppose you've written an application that counts the number of zombies remaining in your neighborhood during a zombie apocalypse. To simulate uncertainty over how many loops are required to get to 0 zombies, my demo code retrieves a timestamp from the operating system and sets the value of the counter (`c`) to some number derived from that timestamp. Because this is a simple example and you don't really want to get trapped in an infinite loop, this code counts down to zero and uses the `break` function to force the loop to end:
+
+```
+package com.opensource.example;
+
+public class Example {
+ public static void main(String[] args) {
+
+ long myTime = System.currentTimeMillis();
+
+ int c;
+
+ if ( myTime%2 == 0 ) {
+ c = 128;
+ } else {
+ c = 1024;
+ }
+
+ while(true) {
+ System.out.printf("%d Zombies\n", c);
+
+ // break for convenience
+ if ( c <= 0 ) { break; }
+ c--;
+ }
+ }
+}
+```
+
+You may have to run it a few times to trigger a different total number of zombies, but sometimes your program iterates 128 times and other times 1,024 times:
+
+```
+$ java ./zcount.java
+1024 Zombies
+1023 Zombies
+[...]
+0 Zombies
+```
+
+Can you tell why the loops end at 0 and not at -1?
+
+### Java loops
+
+Loops give you control over the flow of your program's execution. Iteration is common in programming, and whether you use a while loop, a do while loop, or an infinite loop, understanding how loops work is vital.

-文档写作的 DevOps 指南
-======
-
-将文档写作加入到 DevOps 的生命周期中
-![Typewriter with hands][1]
-
-DevOps 正在挑战技术文档的规范,这在IT历史上是前所未有的。从自动化到提高交付速度,再到拆除瀑布式软件开发生命周期模型,这意味着业务和技术文档的理念需要做出巨大改变。
-
-以下是DevOps对技术文档不同方面的影响。
-
-### 技术作家的角色变化
-
-技术作家必须适应 DevOps。好消息是,许多技术作家已经加入到开发团队中,并且由于拥有合作关系和不断增长的产品知识,这些技术作家很具优势。
-
-但是如果一个技术作家习惯独立工作,并依赖于领域专家的草稿作为文档的基础,那么就需要做一些调整。
-
-进行一些投资以确保文档和其他与项目有关的开发工作获得所需的工具、结构和支持。 从改变[技术作家聘用习惯][2]开始。以[DevOps 的速度][3]编写文档需要重新思考内容规划,并打破DevOps 团队和支持项目的技术作家之间长期存在的隔阂。
-
-DevOps 使开发团队摆脱了传统文档实践的束缚。首先,文档[完成的定义][4]必须改变。一些企业的文化使技术作家成为软件开发的被动参与者。DevOps提出了新的要求--随着 DevOps 文化的转变,技术作家的角色也应发生变化。技术作家需要(且必须适应)DevOps 提供的透明度。他们必须融入 DevOps 团队。取决于组织如何塑造这个角色,将技术作家带入团队可能会带来技能上的挑战。
-
-### 文档标准、方法和规格
-
-虽然 DevOps 还没有影响到技术文档本身,但开源社区已经加强了对应用编程接口(API)文档的帮助质保,已经有不同规模的企业的 DevOps 团队正在使用这些文档。
-
-用于记录 API 的开源规范和工具是个非常值得关注的领域。我想这是由于[谷歌文档季][5]的影响,使得一些专业的技术作家能够接触到开源项目,并解决最关键的文档类项目。
-
-开源 API 属于 DevOps文档讨论。云原生应用集成需求的重要性正在上升。[OpenAPI 规范][6]--一个定义和记录API的开放标准--是在 DevOps 环境下 API 文档的良好资源。然而,该规范会导致文档的创建和更新过程变得很费时,这使其饱受批评。
-
-曾经也有短暂尝试过创建[持续文档][7],并且还有一个来自 CA(现在的Broadcom)的创建[DocOps][8]框架的运动。然而,DocOps 从来没有作为一个行业运动流行起来。
-
-DevOps 文档标准的现状意味着 DevOps 团队(包括技术作家)需要在项目的最初阶段开始创建文档。要做到这一点,需要把文档作为一个敏捷故事和(同样重要的)管理期望来添加,并且把它与年度绩效评估放在一起执行。
-
-### Documentation tools 文档工具
-
-文档的编写应该以一种所有团队成员都可以使用的格式或平台在线进行。MediaWiki、DokuWiki、TikiWiki和其他[开源维基][9]为 DevOps 团队提供了一个编写和维护文档的中央仓库。
-
-让团队选择他们的 wiki,就像让他们选择他们的其他持续集成/持续开发(CI/CD)工具链一样。开源维基强大之处在于其可扩展性。例如,DokuWiki包括一系列的扩展,你可以通过安装这些扩展来创建一个符合你的 DevOps 团队的创作要求的平台。
-
-如果你有足够的野心来加强你的团队的编写和协作能力,[Nextcloud][10](一个开源的云协作套件)是一个让你的 DevOps 团队上网并给他们提供编写文档所需工具的选择。
-
-### DevOps 最佳实践
-
-文档在 DevOps 转型中也发挥着作用。例如,组织从 DevOps 实现效率和流程增益的最佳实践的相关记录,这些信息太重要了,不能靠着 DevOps团中之间口口相传。如果你所在的组织有多个 DevOps 团队,那么文档就是统一的力量,它可以促进最佳实践的标准化,并设置了衡量代码质量的基准指标。。
-
-一般情况下,开发人员承担了记录 DevOps 实践的工作。即使他们的组织有技术作家,他们也可能跨开发团队工作。因此,开发人员和系统管理员能够捕捉、记录和交流他们的最佳实践是很重要的。这里有一些朝正确的方向发展的提示:
-
-* 提前花时间为 DevOps 最佳实践创建标准模板。不要陷入复制在线模板,采访利益相关者和团队来创建一个符合团队需求的模板。
-* 寻找一些方法进行信息收集,例如记录团队会议和使用聊天系统日志来作为文档的基础。
-* 建立一个用于发布最佳实践的 wiki。使用 wiki 可以跟踪编辑和更新。这样的平台可以帮助团队在最佳实践发生变化时进行更新和维护。
-
-当在构建 CI/CD 工具链时记录依赖关系是非常明智的。尤其是当加入新的团队成员时,你会发现这些记录非常有用,另外当团队成员忘记一些事情时,这也是一种保险。
-
-最后,自动化对 DevOps 利益相关者和从业者都很有吸引力。在自动化中断之前,一切都很有趣。拥有自动化运行手册、管理指南和其他内容的文档(并且是最新的)意味着无论何时发生故障,员工都可以让自动化重新工作。
-
-### 最后一些想法
-
-DevOps 对于技术文档来说是一个积极的因素。它将内容开发纳入DevOps生命周期,并打破组织文化中开发人员和技术作者之间的隔阂。没有技术作家的优势,团队就可以使用工具来加快文档创作的速度,以与DevOps的速度相匹配。
-
-您的组织将如何把文档加入到 DevOps 生命周期?请在评论区分享您的经验。

-Linux 中的 `su` 和 `sudo` 命令有什么区别呢?
-======
-
->本文将比较 非 root 用户 提权为 root 用户的两个 **Linux 命令** 的区别。
-
-![bash logo on green background][1]
-
-`su` 和 `sudo` 命令都允许用户执行非特权用户不允许做的系统管理任务,即只有 root 用户能执行的命令。有些人更喜欢 `sudo` 命令:例如 [Seth Kenlon][2] 最近发布的一篇 [《在 Linux 上使用 `sudo` 的 5 个理由》][3],他在其中详细阐述了 `sudo` 命令的许多优点。
-
-但是,相较于 `sudo` 命令,我**更偏好于 `su` 命令**,来做系统管理工作。在本文中,我比较了这两个命令的区别,并解释了为什么我更喜欢 `su` 而不是 `sudo`,但我仍然同时使用这两个命令的原因。
-
-### 过去的系统管理员主要使用 `su` 命令
-
-`su` 和 `sudo` 命令是为**不同的世界**设计的。早期的 Unix 计算机需要全职系统管理员,他们使用 root 用户作为唯一的管理帐户。在这个古老的世界里,有管理员密码的人会在电传打字机或 CRT 终端(例如 DEC VT100)上以 root 用户登录,然后执行一些管理 Unix 计算机的工作。
-
-root 用户还有一个非 root 帐户,用于执行一些非 root 的任务,例如编写文档和管理电子邮件等。在这些 Unix 计算机上通常有许多非 root 帐户,他们都不需要完全的 root 访问权限,只需要以 root 权限运行很少的命令,大约 1 至 2 个就可以了。许多系统管理员以 root 用户登录,完成 root 工作,并在任务完成后,退出 root 会话。系统管理员需要整天以 root 用户来登录,因为 `sudo` 命令需要键入更多的内容才能运行基本命令,因此大多数系统管理员很少使用 `sudo` 命令。
-
-`sudo` 和 `su` 这两个命令都能够提权为 root 用户,但它们实现的方式大不相同。这种差异是由于它们**最初打算用于不同的情况**。
-
-### `sudo` 命令
-
-`sudo` 命令的初衷是让 root 用户能够将他们定期需要的 1 到 2 个特权命令委托给 1 至 2 个非 root 用户。`sudo` 命令允许非 root 用户暂时地获得更高权限,来执行一些特权命令,例如添加和删除用户、删除属于其他用户的文件、安装新软件以及管理现代 Linux 主机所需的任何命令。
-
-`sudo` 命令允许非 root 用户访问 1 到 2 个 _需要更高权限_ 的常用命令,这样可以帮助系统管理员节省来自用户的许多请求,并减少等待时间。`sudo` 命令不会将用户帐户切换为 root 用户,因为大多数非 root 用户永远不应该拥有完全的 root 访问权限。在大多数情况下,`sudo` 允许用户执行 1 或 2 个命令,然后提权就会过期。在这个通常为 5 分钟的短暂的提权时间内,用户可以执行任何需要提权的管理命令。需要继续使用提权的用户可以运行 `sudo -v` 命令来重新验证 root 访问权限,并将提权时间再延长 5 分钟。
-
-使用 `sudo` 命令还有一些副作用,例如生成非 root 用户使用命令的日志条目及其 ID。这些日志可以在之后作为出现问题的检验,来给用户更多的操作培训。你以为我会说“责备”用户,对吗?
-
-### `su` 命令
-
-`su` 命令能够将非 root 用户提权到 root 权限——事实上,能让非 root 用户成为 root 用户。唯一的要求是用户知道根密码。因为用户已经以 root 权限登录,所以之后的操作就没有限制了。
-
-`su` 命令所提供的提权没有时间限制。用户可以作为 root 执行命令,不需要进行重新认证是否有 root 权限。完成任务后,用户可以执行退出命令 `exit`,从 root 用户恢复到自己原来的非 root 帐户。
-
-### `su` 和 `sudo` 在使用上的争议和变化
-
-最近在 `su` 与 `sudo` 的使用上存在一些分歧。
-
-> 真正的系统管理员不会使用 `sudo`。——保罗·威尼斯(Paul Venezia)
-
-Venezia 在他的 [InfoWorld 文章][4] 中辩称,对于许多担任系统管理员的人来说,`sudo` 是一个不必要的工具。他没有花太多时间为这个观点进行解释,他只是把它说成了一个事实。我同意他对于系统管理员的观点,因为我们不需要 `sudo` 来完成我们的工作。事实上,`sudo` 使得事情变得更复杂了。
-
-然而,
-
-> 这时代正在“变革”当中。——鲍勃·迪伦
-
-迪伦是对的,尽管他没有为电脑唱歌(LCTT 译注:鲍勃·迪伦是美国创作歌手、艺术家和作家,这里指他不是针对于电脑而说的)。
-
-自从**个人计算机**时代到来以来,计算机的管理方式发生了重大变化。在许多环境中,计算机的使用者也是它的管理员,这使得为这些用户提供一些对 root 权限的访问是有必要的。
-
-一些现代发行版,例如 Ubuntu 及其衍生版本,只能使用 `sudo` 命令来执行特权命令。在这些发行版中,用户无法直接以 root 用户身份登录,甚至无法通过 `su` 切换到 root,因此需要 `sudo` 命令来允许非 root 用户获得 root 权限。在这一环境中,所有系统管理任务均使用 `sudo` 来执行。
-
-通过锁定 root 帐户并将常规用户帐户添加到 wheel 组,可以进行此配置,但是这种配置很容易被绕过。接下来,让我们在任何 Ubuntu 主机或 VM 上尝试一些小实验吧。我在这里说明一些我实验的设置,以便你可以根据需要来重现它。我安装的是 Ubuntu 16.04 LTS1,并使用 VirtualBox 将其安装在 VM 中。在安装过程中,我创建了一个非 root 用户 `student`,为了简便起见我给这个用户设置了一个简单的密码。
-
-以 `student` 用户身份登录 Ubuntu,并打开终端。查看 `/etc/shadow` 文件中的 root 条目,其中存储了经哈希的密码。
-
-```
-student@ubuntu1:~$ cat /etc/shadow
-cat: /etc/shadow: Permission denied
-```
-
-可以看到终端拒绝了我们对 `/etc/shadow` 的访问,因此我们无法查看 `/etc/shadow` 文件。所有发行版都是如此,以防止非特权用户看到和访问加密的密码,因为非特权用户可能会使用常见的黑客工具来破解这些密码。
-
-现在,让我们使用 `su -` 命令来成为 root 用户。
-
-```
-student@ubuntu1:~$ su -
-Password:
-su: Authentication failure
-```
-
-认证失败的原因是因为根帐户没有密码、并且被锁定了。接下来,使用 `sudo` 命令查看 `/etc/shadow` 文件。
-
-```
-student@ubuntu1:~$ sudo cat /etc/shadow
-[sudo] password for student:
-root:!:17595:0:99999:7:::
-
-student:$6$tUB/y2dt$A5ML1UEdcL4tsGMiq3KOwfMkbtk3WecMroKN/:17597:0:99999:7:::
-
-```
-
-在这里,我仅截取了部分结果,只显示 root 和 `student` 用户的条目。我还缩短了加密密码,以便该条目能显示在一行中。各个字段以冒号(`:`)分隔,第二个字段是密码。请注意,root 的密码字段是一个感叹号(`!`),这表明 root 帐户已被锁定,且无法使用。
-
-现在,要将根帐户变成一个合适的系统管理员,你只需为根帐户设置密码。
-
-```
-student@ubuntu1:~$ sudo su -
-[sudo] password for student:
-root@ubuntu1:~# passwd root
-Enter new UNIX password:
-Retype new UNIX password:
-passwd: password updated successfully
-root@ubuntu1:~#
-```
-
-现在,你可以直接以 root 身份登录到控制台,或者直接使用 `su` 登录到 root,而不是在每个命令前都加一个 `sudo`。当然,你也可以在每次想以 root 身份登录时,使用 `sudo su -`,但这又是何必呢?
-
-请不要误解我的意思。像 Ubuntu 这样的发行版非常好,多年来我已经使用了其中的几个。在使用 Ubuntu 和相关发行版时,我做的第一件事就是设置一个 root 密码,这样我就可以直接以 root 身份登录。其他发行版,如 Fedora 及其相关发行版,现在在安装过程中提供了一些有趣的选择。我注意到的第一个 Fedora 版本是 Fedora 34,我在写我的一本即将出版的书时安装了很多次。
-
-在安装页面上,可以找到其中一个安装选项,来设置 root 密码。这个新选项允许用户以锁定 Ubuntu root 帐户的方式选择“锁定 root 帐户”。此页面上还有一个选项,允许使用密码以 root 身份远程 SSH 登录到此主机,但这仅在 root 帐户解锁时有效。第二个选项位于允许创建非根用户帐户的页面上。此页面上的选项之一是“让此用户成为管理员”。选中此选项后,用户 ID 将添加到一个名为 wheel 组的特殊组中,该组授权该组的成员使用 `sudo` 命令。Fedora 36 甚至在该复选框的描述中提到了 wheel 组。
-
-可以将多个非 root 用户设置为管理员。使用此方法指定为管理员的任何人都可以使用 `sudo` 命令在 Linux 计算机上执行所有管理任务。Linux 在安装时只允许创建一个非 root 用户,所以其他新用户可以在创建时添加到 wheel 组中。root 用户或其他管理员可以使用文本编辑器或 `usermod` 命令直接将现有用户添加到 wheel 组。
-
-在大多数情况下,今天的管理员只需要执行一些基本任务,例如添加新的打印机、安装更新或新软件,或者删除不再需要的软件。这些 GUI 工具需要 root 或管理密码,并将接受来自管理员用户的密码。
-
-### 在 Linux 上,我是怎么使用 `su` 和 `sudo` 的呢
-
-我**同时使用 `su` 和 `sudo`**。它们都是我所使用的很重要的系统管理员工具。
-
-我不锁定根帐户,因为我需要用根帐户来运行我的 [Ansible][5] 脚本和我编写的 [rsbu][6] Bash 程序,来执行备份。这两个程序都需要以 root 身份运行,我编写的其他几个管理 Bash 的脚本也是如此。我**使用 `su` 命令**,切换到 root 用户,这样我就可以执行这些脚本和许多其他常见的命令。当我需要确定问题和解决问题时,使用 `su` 命令将我的权限提升到 root 十分有用,因为我不希望 `sudo` 带来的提权会话超时。
-
-当非 root 用户需要执行这些任务时,我**使用 `sudo` 命令**,来执行需要 root 权限的任务。我在 sudoers 文件中设置了非根帐户,只允许访问完成任务所需的 1 到 2 个命令。当我只需要运行 1 个或 2 个需要提权的快速命令时,我自己也会使用 `sudo` 命令。
-
-### 结论
-
-实际上只要你把工作完成好了,你使用什么工具都无大碍。你使用的是 vim 还是 Emacs,是 systemd 还是 SystemV,是 RPM 亦或是 DEB,是 `sudo` 亦或是 `su`,在结果上会有什么区别呢?这里的关键在于你应该使用**最适合你的工具**。Linux 和开源软件的最大优势之一是通常有许多选项可用于我们需要完成的任务。
-
-`su` 和 `sudo` 都各有长处,如果正确使用的话,两者都是非常安全的。我选择同时使用 `su` 和 `sudo` 命令,基于它们的历史功能,因为这对我来说十分有用。对于我自己的大部分工作,我更喜欢 `su` 命令,因为它与我的工作流程最适配。
-
-在评论区分享你喜欢的工作方式吧!

+lnav: 用于 Linux 台式机和服务器的高级日志文件浏览器
+======
+
+**如果你想调试或排除任何问题,你需要一个像 lnav这样的高级日志文件查看器。它在任何 Linux 系统的终端都能创造奇迹。**
+
+### lnav: 日志文件查看器
+
+lnav 可以即时解压缩所有的压缩日志文件,并将它们合并在一起进行漂亮的显示。显示是根据错误/警告的类型进行解析和格式化的,这有助于快速浏览成千上万的日志,特别是在服务器中。
+
+在分析日志的时候,时间戳是非常重要的。所以 lnav 根据时间戳合并多个日志,这对追踪系统问题很有帮助。
+
+大多数重要的日志文件格式检测都是内置的,如下:
+
+- 常见的网络访问日志格式
+- CUPS page_log
+- Syslog
+- Glog
+- VMware ESXi/vCenter 日志
+- dpkg.log
+- uwsgi
+- “通用”:任何以时间戳开头的信息
+- Strace
+- sudo
+- GZIP, BZIP
+
+这还不是全部,lnav 还能实现以下功能,使其成为 Linux 系统的重要应用。
+
+- 根据正则表达式过滤消息
+- 错误的时间轴视图
+- 漂亮的打印视图,这有助于重新格式化
+- 使用 SQL 查询日志
+- 在搜索时,日志会实时更新。
+- 通过正则表达式高亮显示语法(比如你想在整个日志中找出一个 IP 地址)
+- 显示的日志中任何单词的 Tab 补全!!
+
+![lnav 在 ubuntu 中运行][1]
+
+要查看上述功能的截图和了解更多信息,请访问[本页面][2] 。
+
+### 如何安装
+
+这个程序在 Ubuntu、Debian 的官方仓库中可以找到。使用以下命令安装它。
+
+```
+sudo apt install lnav
+```
+
+而对于 Fedora、RHEL 用户,使用下面的命令:
+
+```
+sudo dnf install lnav
+```
+
+另外,开发者还提供了一个离线的独立可执行文件,你不需要安装。你可以从 [GitHub 发布页][3]下载压缩包,然后按以下方式执行:
+
+```
+./lnav
+```
+
+**注意**:它也可用于 macOS,你可以在上述 GitHub 页面找到。
+
+### lnav: 如何使用(基础)
+
+简单的命令语法是:
+
+```
+lnav [options] [logfile1 logfile2 …]
+```
+
+如果你只运行 lnav 命令,它会显示你系统中的所有日志(/var/log/messages 和 /var/log/syslog)
+
+```
+lnav
+```
+
+要查看任何特定的日志文件,在命令行中输入:
+
+```
+lnav /var/log/syslog
+```
+
+使用 -t 参数在你的日志输出中添加时间戳:
+
+```
+lnav -t /var/log/syslog
+```
+
+以下是 lnav 的一些关键开关:
+
+```
+-d file 将调试信息写入给定的文件。
+-a 加载所有最新的日志文件类型。
+-r 也加载较早的旋转日志文件。
+-t 在标准输入中读入的数据行上预加时间戳。
+-w file 将标准输入的内容写入该文件。
+-c cmd 在文件加载后执行命令。
+-f path 执行给定文件中的命令。
+-n 不使用 curses UI 运行(无头模式)。
+```
+
+![lnav 在 Ubuntu 22.04 中运行][4]

-在 Linux 上试试这个 Java 文件管理器
-======
-
-计算机是奇特的文件柜,里面装满了等待引用、交叉引用、编辑、更新、保存、复制、移动、重命名和组织的虚拟文件夹和文件。在本文中,我将介绍一下 Linux 系统的文件管理器。
-
-在 Sun Microsystem 时代的末期,出现了一种叫做 Java 桌面系统的东西,奇怪的是它_不是_用 Java 编写的。相反,它是(根据当时的 sun.com 上的描述)“对集成和优化的桌面软件的明智选择,大部分基于开源代码和开放标准”。它基于 GNOME,带有办公套件、电子邮件和日历应用、即时消息和“Java 技术”。我发现自己在思考用 Java 创建桌面需要什么。客观地说,桌面实际上并没有那么多。一般的共识似乎是桌面由面板、系统托盘、应用菜单和文件管理器组成。
-
-想象一个实际的 Java 桌面是一个有趣的思维练习。不足以以此为目标启动一个开源项目,但足以在网络上快速搜索必要的组件。事实证明,有人用 Java 编写并维护了一个文件管理器。
-
-### JFileProcessor
-
-我找到的 Java 文件管理器叫做 JFileProcessor,简称 JFP。这不仅在 Java 中,而且在 [Groovy][1](一种流行的 Java 脚本语言)中都是一项迷人的练习。
-
-![Image of the JfileProcessor folders.][2]
-
-作为文件管理器,JFileProcessor 在设计和功能上都采用了最小化的方法。它允许你查看、打开、移动、复制、剪切或删除本地系统和远程系统上的文件。它不是特别定制化的,它没有额外的功能,如拆分面板或可移动面板。除了管理文件外,它不围绕任何中心主题构建。JFileProcessor 在某种程度上令人耳目一新,因为它很简单。这是一个文件管理器,仅此而已。有时这就是你在文件管理器中想要的全部。
-
-我之前写过关于[设置 Java Swing 主题][3]的方式,从技术上讲,该技术是这个开源应用的一个选项。但是,我认为这个应用的部分魅力在于 OpenSolaris 称之为 “Blueprint” 的主题。这是 Java 的怀旧外观,我喜欢以其原生 GUI 外观运行它,作为对我的 OpenSolaris(现为 OpenIndiana)笔记本电脑的回忆。
-
-
-### 用户体验
-
-除了设计,真正重要的是用户体验。JFileProcessor 只有三个你日常使用的按钮:向上、后退和前进。它们未绑定到键盘快捷键,因此你必须单击按钮才能导航(或使用 **Tab** 键选择按钮)。在使用图形应用时,我经常使用键盘快捷键,所以当我尝试浏览我的系统时,这大大减慢了我的速度。但是,有时我实际上只是懒洋洋地浏览文件,因此 JFileProcessor 完全按照我的需要工作。
-
-JFileProcessor 也有一个搜索组件。只要你设置合理的起始文件夹,搜索就会快速而智能,同时允许适用 glob 和正则模式搜索。例如,当我搜索特定的电子书或漫画档案或游戏规则手册时,或者任何时候我粗略地知道该目录包含一个项目但懒得一直点击到目的地址。在子目录中快速搜索,必然会得到明显的结果,然后双击打开文件,不管我设置了什么XDG偏好(Evince用于PDF,Foliate用于电子书,等等)。
-
-右键单击任何文件或目录会弹出上下文菜单。它具有你期望的大部分常见任务:复制、剪切、粘贴、删除、重命名、新建。它也有一些不错的额外功能。
-
-![Right-click context menu in JFileProcessor][4]
-
-例如,你可以只将文件名复制到剪贴板或保存文件路径。你还可以运行一些脚本,包括用于批量重命名文件的脚本、用于对选定文件运行命令的脚本、用于创建 ZIP 或 TAR 存档的脚本等等。当然,编码器有多种选择,包括在当前位置打开终端和打开新的编码窗口。
-
-### 安装
-
-我是 Java 的忠实粉丝。它是一种清晰的语言,具有合理的分隔符和对跨平台兼容性的坚定立场。我喜欢它作为一种语言,我喜欢看到程序员用它创造的东西。
-
-JFileProcessor 的名字很贴切。这是一种处理文件的有效方法,从某种意义上说,JFileProcessor 为你提供了一个简单的窗口来查看系统上的文件数据,并允许你以图形方式与它们进行交互,就像你可能在终端中与它们交互一样。它不是我用过的最高效的文件管理器,也不是功能最多的一个。然而,这是一个令人愉快的应用,为你提供了文件管理所需的基本工具,其相对较小的代码库使你可以在下午阅读一些精彩的内容。
