如何以非代码形式贡献开源
|
||||
======
|
||||
|
||||
> 事实上，有无穷无尽的方法来为开源做贡献，其中一个简单的方法就是回答我们的投票问题。
|
||||
|
||||
|
||||
|
||||
你是如何参与开源贡献的呢？我们组织了一个投票，结果如下：
|
||||
|
||||
* 提交错误报告 - 67 票（35%）
|
||||
* 解答用户的问题 - 39 票（20%）
|
||||
* 写作（指南、故事、文档等） - 73 票（38%）
|
||||
* 其他 - 12 票（6%）
|
||||
|
||||
我的第一次开源贡献可以追溯到 20 世纪 80 年代中期，当时我们的机构第一次连上了 [UseNet][2]，在那里我们发现了贡献代码，以及在其开发和支持过程中和别人分享的机会。
|
||||
|
||||
在今天，我们有无尽的贡献开源的机会。无论是贡献代码，还是制作一个视频教程，都是贡献的一种途径。
|
||||
|
||||
不过，我将直接跳过整个贡献代码的部分。诚然，我们中有许多写代码但不认为自己是开发者的人，他们也可以 [贡献代码][3]。但是，我更想提醒大家，还存在很多 [非代码形式可以贡献开源][4]。接下来，我会谈到其中的三种。
|
||||
|
||||
### 提交错误报告
|
||||
|
||||
有一种重要而具体的贡献形式，它可以被描述为“不要畏惧 [提交一个像样的错误报告][6]”以及 [与此相关的所有后果][5]。有时，要 [提交一个像样的错误报告][6] 是很有挑战性的。比如说：
|
||||
|
||||
* 某些错误可能很难记录或描述。当计算机启动时，屏幕上可能会出现又长又复杂的信息，其中包含各种不能理解的代码。或者屏幕上可能显示有一些“异常行为”，但是却没有提供具体的错误信息。
|
||||
* 某些错误可能很难重现。它可能只发生在某些特定的硬件/软件配置上，或者它可能很少被触发，或者错误的产生场景不明确。
|
||||
* 某些错误可能与一个非常特殊的开发环境配置有关，但是这个配置庞杂混乱，无法分享，需要先耗费大量精力创建一个精简后的例子才行。
|
||||
* 当向发行版报告一个错误时，维护者可能会建议将该错误提交给上游，这有时会需要付出大量的工作，因为发行版所提供的版本不是上游社区感兴趣的主要版本。（当发行版提供的版本落后于官方支持的发布和开发版本时，就会有这种情况发生）。
|
||||
|
||||
尽管如此，我还是鼓励那些潜在的错误报告者（包括我）继续努力，并尝试让错误得到完整的记录和确认。
|
||||
|
||||
但如何开始呢？你可以使用你最喜欢的搜索工具寻找类似的错误报告，看看它们是如何描述的，它们被归档在哪里，等等。你也可以留意你使用的发行版（例如，[Fedora][7]、[openSUSE][8]、[Ubuntu][9]）或软件包（[LibreOffice][10]、[Mozilla][11]）的错误报告页面，它们定义了正式的报告机制，你可以按步骤为他们报告相关错误。
|
||||
|
||||
### 解答用户的问题
|
||||
|
||||
我潜伏在各种邮件列表和 [论坛][13] 里，偶尔也会冒个泡，例如 [Ubuntu 质量控制团队][12] 和 [论坛][13]、[LinuxQuestions.org][14]，以及 [ALSA 用户的邮件列表][15] 等。在这里，我的贡献可能与错误报告的关系不大，更多的是记录复杂的用例。不过，看到有人热心帮助他人，解决他人在某个问题上的遇到的麻烦，对每个人来说，这都是无疑一种很棒的体验。
|
||||
|
||||
### 从事开源相关的写作
|
||||
|
||||
最后，另一个我非常喜欢贡献的领域是 [撰写][16] 关于使用开源软件的文章。无论是使用指南，还是对某一特定问题的不同解决方案进行比较评估，或者只是笼统地探索一个感兴趣的领域（就我而言，是使用开源音乐播放软件来享受音乐）。一个类似的选择是制作一个教学视频。你很容易就可以做到边演示一些复杂的桌面操作（比如用 GIMP 创建一个绚丽的标志），边 [录制桌面][17]。而那些精通两种或多种语言的人，也可以考虑将现有的使用指南或视频翻译成另一种语言。

Markdown 初学者指南
|
||||
======
|
||||
|
||||
|
||||
|
||||
在我的工作中，我经常要写代码、写与代码相配套的文档、创建网页、进行文本恢复项目。我在学校的时候还写过几篇正式的论文，也包括写课堂笔记，几乎每节课都写。
|
||||
|
||||
我几乎在我所有的写作中都使用 Markdown，它对我来说是一个节省时间的好工具。
|
||||
|
||||
在这篇文章中，我将分享我使用 Markdown 的体会。你将会了解以下内容：
|
||||
|
||||
* 什么是 Markdown ？
|
||||
* 它是怎么工作的？
|
||||
* Markdown 的基本语法和怎样使用它们。
|
||||
|
||||
### 什么是 Markdown ？
|
||||
|
||||
假如你是 Markdown 新手，它是一个为网络写手转换文本到 HTML 格式的工具。Markdown 文档遵循一种特定的语法，容易阅读和写作。它们是纯文本，所以能够通过电脑上的任何文本编辑器来创建。然后这些文档能够转换成网页 —— 而网页是用一个叫做 HTML 的语言标记创建的。
|
||||
|
||||
Markdown 只是一种不必（即使知道怎么做）写 HTML 代码就能够创建网页的方式。实际上，如果你不转换成 HTML 的话，Markdown 甚至是个对纯文本格式化的好方法。有人曾这样对我描述 Markdown ：
|
||||
|
||||
|
||||
> “ _它不是所见即所得，而是所见即所意_ ”。
|
||||
|
||||
然而，Markdown 不只是一个简单的格式化体系，它也是一个纯文本格式转化到 HTML 的一个软件工具。
|
||||
|
||||
这就是为什么语法很重要。如果你想在网页上起个标题，Markdown 将会基于你标题前面的字符来创建。Markdown 的一些语法示例如截图所示：
|
||||
|
||||
![Markdown to HTML conversion][1]
|
||||
|
||||
### 所以我怎样才能使纯文本文件转换成 HTML 格式呢?
|
||||
|
||||
John Gruber 的 Markdown 是一个运行在命令行上的 Perl 脚本。也就是说，它可以读取你创建的 Markdown 文本并用它来构建网页。
|
||||
|
||||
由于有 [许多著名的编辑器][2] 可以为你做这个转换，我在这里尽量避免使用命令行。不仅如此，许多这样的编辑器会让你写下你的文本，并同时向你展示网页的样子（称为渲染）。
|
||||
|
||||
Markdown 编辑器总的来说设置了两帧：左边部分是你要写你文本的地方，右边部分是用 HTML 语言显示给你格式化后文本的样子：
|
||||
|
||||
![Most Markdown editors have two panes to write and preview the text][3]
|
||||
|
||||
当你用它满意地完成你的写作，只需保存 Markdown 文件即可。就像这样，之后一旦你需要编辑和修改的时候，你就会用到它。文件保存后，你可以用编辑器将 Markdown 文档导出为 HTML 格式的文档。
|
||||
|
||||
编辑器用你的 Markdown 作为参考创建网页。你的 Markdown 文档在导出时不会修改，你仍然拥有源文档，同时创建一个独立的、新的 HTML 文档（网页），你可以把它放到一个网页服务器上。
|
||||
|
||||
**注意**：许多 Markdown 编辑器也可以将你的 Markdown 文档导出为其他格式，比如 `.doc`、`.docx` 和 `.pdf`。之后你可以了解这些高级设置和你可能需要的额外软件。
|
||||
|
||||
### Markdown 基础语法
|
||||
|
||||
为了让 Markdown 新用户快速了解，我将把这部分内容限制在我最常使用的语法上。我相信这些将是最有帮助的 - 你可以在现在就提高工作效率，同时了解更多关于 Markdown 以后能为你做什么。
|
||||
|
||||
#### 写标题
|
||||
|
||||
我经常使用 `#` 字符来表示标题。这里有六个等级：
|
||||
|
||||
```
|
||||
# 一级标题
|
||||
## 二级标题
|
||||
### 三级标题
|
||||
#### 四级标题
|
||||
##### 五级标题
|
||||
###### 六级标题
|
||||
```
|
||||
|
||||
还有一种标题类型，是在文本下使用下划线。我很少使用这种类型的标题，我只限于使用两种：一种是使用 `=` 字符表示的双下划线，生成 `H1` 标题。一种是使用 `-` 字符表示的单下划线，生成 `H2` 标题：
|
||||
|
||||
```
|
||||
一级标题
|
||||
===============
|
||||
|
||||
二级标题
|
||||
---------------
|
||||
```
|
||||
|
||||
![][4]
|
||||
|
||||
#### 段落
|
||||
|
||||
段落被空行隔开（确保段落之间有一个空行）。首行不要缩进。在 Markdown 里用 `Tab` 键或者空格键缩进有着不同的目的和作用。
|
||||
|
||||
段落是一个文本块，不应该用空格键和 `Tab` 键来缩进。它可以有一行或者多行。要结束这一段另起一段，点两下回车键；段落通过一个空行分开。
|
||||
|
||||
![][5]
|
||||
|
||||
#### 换行
|
||||
|
||||
请记住，对于段落，必须用空行来分隔它们，这要通过按两次回车键来实现。Markdown 对此很严格。
|
||||
|
||||
Markdown 不支持 “<ruby>强制插入换行符<rt>hard-wrapped</rt></ruby>” 或者 “<ruby>固定行长度<rt>fixed-line-length</rt></ruby>” 段落。那就是说，单击回车键一次将不会强制文本换到新的一行。它可能在编辑窗口显示，但是 HTML 格式下不显示。
|
||||
|
||||
然而，有时你可能需要拆分段落或者换行。Markdown 确实有一种方法可以做到，但是它一开始看起来可能有一点奇怪：**换行是通过用两到多个空格键然后点一次回车键完成的。**
|
||||
|
||||
![][6]
|
||||
|
||||
这里有一个短诗的范例。每行以两个空格结束。最后一行，由于是这个小节的结束，没有额外的空格。因为它是这个诗句（段落）的结束，我双击回车键两次：
|
||||
|
||||
```
|
||||
Baa, baa black sheep,
|
||||
Have you any wool?.
|
||||
Yes, sir. Yes, sir.
|
||||
Three bags full.
|
||||
```
|
||||
|
||||
在一行的最后加两个空格来创建一个换行，可能需要时间去习惯。
|
||||
|
||||
![][7]
|
||||
|
||||
#### 水平线
|
||||
|
||||
水平线非常适合将文本拆分为多个部分。
|
||||
|
||||
用三个或更多的破折号 `-` ，下划线 `_` ，或者星号 `*` 来做水平线，像这样：
|
||||
|
||||
```
|
||||
---
|
||||
|
||||
***
|
||||
|
||||
___
|
||||
```
|
||||
|
||||
你甚至可以在字符之间输入空格：
|
||||
|
||||
```
|
||||
- - -
|
||||
```
|
||||
|
||||
在文章和报告中我不经常使用水平线，但是在日记、系统日志和课堂笔记中对我很有用。
|
||||
|
||||
![][8]
|
||||
|
||||
#### 用加粗和斜体来强调文本
|
||||
|
||||
当你想让一个单词或者短语脱颖而出，引起注意，你可以让它加粗或者斜体显示。斜体和加粗文本可以在两种方式中任选其一。第一种是用星号 `*` 将其包括，第二种是用下划线 `_` 的方式。
|
||||
|
||||
使一个单词或者短语斜体显示，用一个下划线或者星号来括住文本。使一个单词或者短语加粗，使用两个下划线或者星号来括住文本：
|
||||
|
||||
```
|
||||
用星号来显示 *斜体* 。
|
||||
|
||||
用下划线来显示 _斜体_ 。
|
||||
|
||||
用星号来显示 **加粗** 。
|
||||
|
||||
用下划线来显示 __加粗__ 。
|
||||
```
|
||||
|
||||
记住两边使用相同的字符。单词或短语的一面是星号，另一面是下划线，将不会生效。相同字符必须在单词或者短语的两边。
|
||||
|
||||
![][9]
|
||||
|
||||
#### 块引用
|
||||
|
||||
块引用被用来直接引用。如果你正在写博客，你想重复本杰明•富兰克林说过的话，你可以使用块引用。
|
||||
|
||||
一个右尖括号被用来指定块引用：
|
||||
|
||||
```
|
||||
> 这是块引用。
|
||||
|
||||
>> 如果你想进一步再次块引用，使用两个右尖括号。
|
||||
```
|
||||
|
||||
![][10]
|
||||
|
||||
#### 在 Markdown 中添加超链接
|
||||
|
||||
超链接非常酷。在基础版的 Markdown 语言有三种方式创建超链接，在这里我只讲两种：普通连接和自动连接。
|
||||
|
||||
第三种链接被称为参考链接，在 Markdown 语言的基础版和高级版都支持。我想让你快速入门。你可以在准备好的时候找找参考链接的资料。
|
||||
|
||||
普通链接可以让你链接到各种各样的网站。网站名称或者你要使用的短语被放置在中括号 `[]` 中。真实的链接地址在小括号 `()` 中。
|
||||
|
||||
```
|
||||
现在去看看 [Linux 中国](https://linux.cn) 。
|
||||
```
|
||||
|
||||
自动连接通过用尖括号 `<>` 括住链接地址。这个链接是一个实际的地址（可以是网址或者电子邮件地址）。拼写出来的链接被转换到 HTML 的时候，就变成了有效的链接。
|
||||
|
||||
```
|
||||
<http://automatic-link-to-url.com/>
|
||||
|
||||
<name@emailaddress.com>
|
||||
```
|
||||
|
||||
当你想在文本中拼写出网址时，这很有用：
|
||||
|
||||
![][11]
|
||||
|
||||
#### 在 Markdown 中添加图片
|
||||
|
||||
链接图片几乎与链接网站一样。网站链接和图片链接微小的不同是，图片链接以感叹号 `!` 开始。
|
||||
|
||||
图片名称或者图片描述放置在中括号 `[]` 里。实际链接放置在小括号 `()` 里。
|
||||
|
||||
你可以像这样嵌入图片：
|
||||
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
这儿有一个示例图像链接。这是一个示例链接，没有这个图片，但是这是个好例子，显示了实际链接应该有的样子：
|
||||
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
![][12]
|
||||
|
||||
#### 列表
|
||||
|
||||
制作列表有很多原因。它们可能用来作为代办事项、大纲中的主题元素、组装项目中的明细栏等等。列表有两种主要类型：无序列表和有序列表。
|
||||
|
||||
无序列表没有编号；这些就是我们在许多文档中所看到的列表项。有序列表是有编号的。
|
||||
|
||||
要创建一个有序（有编号的）列表，只需在每行用一个数字开始，像这样：
|
||||
|
||||
```
|
||||
1. 项目 一。
|
||||
2. 项目 二。
|
||||
3. 项目 三。
|
||||
```
|
||||
|
||||
无序列表没有编号，但要在列表每个项目的开始使用一个星号 `*` 、一个加号 `+` ，或者一个减号 `-` 。我偏向于使用一个星号或者减号，你可以选择适合你的：
|
||||
|
||||
```
|
||||
* 项目 一。
|
||||
+ 项目 二。
|
||||
- 项目 三。
|
||||
```
|
||||
|
||||
子项目可以通过缩进被添加到有序和无序列表中，像这样：
|
||||
|
||||
```
|
||||
1. 项目 一
|
||||
1. 子项目 一
|
||||
2. 子项目 二
|
||||
2. 项目 二
|
||||
3. 项目 三
|
||||
```
|
||||
|
||||
![][13]
|
||||
|
||||
### Markdown 语法速查表
|
||||
|
||||
这是一个简短的 Markdown 语法列表为你作为参考，这个列表已经在本小结中介绍。
|
||||
|
||||
如果你决定使用 Markdown 作为写作工具，你会发现 Markdown 会让写作变得更加简单。
|
||||
|
||||

|
||||
|
||||
### 结语
|
||||
|
||||
Markdown 可以做比我描述的更多的事情。我写作的很大一部分是用我在这里介绍的 Markdown 语法完成的 - 而这些是我最常使用的项目，即使是在更复杂的项目中。
|
||||
|
||||
如果这些看起来太简单了，那么说明它真的很容易。Markdown 用来完成简单的写作任务，但是你不必完全听我的。你可以尝试一下！不必安装 Markdown 编辑器；你可以在线尝试。这里有几个 [优秀的在线 Markdown 编辑器][16]。这里我喜欢用这三个：
|
||||
|
||||
- John Gruber’s [Dingus][17]
|
||||
- [Editor.md][18]
|
||||
- [Dillinger][19]
|
||||
|
||||
Editor.md 和 Dillinger 会让你看到你的 Markdown 文本作为 HTML 实时渲染的效果。 Dingus 不能实时预览，但是在参考页有 Markdown 的语法速查表。
|
||||
|
||||
![][20]
|
||||
|
||||
用以上这些在线编辑器尝试一下文章中的示例。也可以尝试一下你自己的想法。这将使你在可能致力于学习更多的知识之前习惯于 Markdown。

使用 Twister UI 提升你的 Linux Mint 和 Xubuntu 视觉感受
|
||||
======
|
||||
|
||||
|
||||
|
||||
> Twister UI 是给你的 Linux Mint 和 Xubuntu 提供视觉提升的最简单方法。以下是方法。
|
||||
|
||||
[Twister UI][1] 可以安装在已有的 Linux Mint 和 Xubuntu 系统上。Pi 实验室创造了这个用户界面，他们为树莓派和相关硬件开发了 [Twister OS][2]。
|
||||
|
||||
### Twister UI
|
||||
|
||||
Twister UI 是一套用于 [Linux Mint][3] 和 Xubuntu 的软件包集合，它带来了几个流行的操作系统特定的主题和配置，开箱即用。你只需点击一个按钮就可以应用它们，而不需要单独下载图标、主题或光标。
|
||||
|
||||
其最新版本提供了以下操作系统的开箱即用的桌面主题、图标、声音和其他设置变化。
|
||||
|
||||
* 原生 Twister 操作系统主题
|
||||
* Windows 98、Windows 7、Windows XP
|
||||
* Windows 11、Windows 10
|
||||
* iTwister 和 iTwister Sur（类似 macOS）
|
||||
|
||||
#### 它是如何工作的？
|
||||
|
||||
该团队提供了自动脚本，从 GitHub 下载所有流行的操作系统特定的主题、声音等。然后该脚本修改它们，从 Ubuntu 仓库下载额外的包，并整体安装这个附加组件。安装程序自己负责安装一切，你需要做的就是等待。
|
||||
|
||||
在向你解释如何安装之前，让我们看看这个操作系统<ruby>增强模组<rt>MOD</rt></ruby>的一些截图和功能。这些截图来自应用了这个操作系统增强模组的 Linux Mint Xfce 版。
|
||||
|
||||
#### 它的外观（截图）

|
||||
|
||||
![Twister UI – Windows XP Theme][5]
|
||||
|
||||
![native Twister OS theme][6]
|
||||
|
||||
#### Twister UI 软件包的内容
|
||||
|
||||
该软件包有它自己的设置应用，名为 ThemeTwister。你可以用它来快速切换主题。你可以随心所欲地在它们之间转换，而不会破坏什么。
|
||||
|
||||
该项目还默认安装了一些优秀的开源软件包。它安装了 Lutris、Steam 游戏平台以帮助你快速玩游戏。它还为用户安装了 Discord、Wine 模拟器。
|
||||
|
||||
正如你所看到的，考虑到这个附加组件的用户群，该团队仔细斟酌了要安装哪些软件包。
|
||||
|
||||
### 如何安装
|
||||
|
||||
如果你打算安装这个，我建议在 Linux Mint Xfce 版和 Xubuntu 中使用这个包。不要试图在其他 Linux 发行版中安装它（我在阅读文档之前就试过了，我把我的 Fedora 系统搞得一团糟，所以不要在其他发行版中尝试）。
|
||||
|
||||
其要求是安装在 Linux Mint Xfce 或 Xubuntu（无论是 32 位还是 64 位）。它还需要大约 5GB 的磁盘空间。
|
||||
|
||||
首先，从下面的链接中下载该软件包，其中包含 Torrent 链接。它不是一个 ISO 文件。它由三个文件组成，其中一个是实际的脚本。
|
||||
|
||||
> [下载 Twister UI][1]
|
||||
|
||||
下载完毕后，打开下载的文件夹，你应该看到一个扩展名为 `.run` 的文件（如下图所示）。
|
||||
|
||||
![Give the execute permission to the run file][7]
|
||||
|
||||
改变该文件的权限，使其可执行。然后通过终端运行它。
|
||||
|
||||
该脚本需要管理员密码，所以在要求时就提供这个密码。在你开始安装之前，请确保你有稳定的网络连接，以便随时下载其他软件包。
|
||||
|
||||
![Starting the installation script][8]
|
||||
|
||||
下载和安装需要一些时间。这取决于你的网速，可能需要 15 到 20 分钟左右。
|
||||
|
||||
你需要知道，该安装程序将取代默认的 Plymouth ，并会 [更新 initramfs][9]。
|
||||
|
||||
安装完成后，脚本应该会提示你重新启动。
|
||||
|
||||
重启后，登录到你的 Linux Mint Xfce 或 Xubuntu 系统。
|
||||
|
||||
### 如何改变主题
|
||||
|
||||
如果你使用的是 Linux Mint Xfce 版，在改变主题之前，你需要做以下额外的改变以获得最佳效果：
|
||||
|
||||
* 打开“<ruby>应用程序菜单<rt>Application Menu</rt></rt></ruby> > <ruby>设置<rt>Settings</rt></ruby> > <ruby>桌面<rt>Desktop</rt></ruby>”，在“<ruby>图标<rt>Icon</rt></ruby>”标签下，取消勾选“<ruby>使用自定义字体大小<rt>Use custom font size</rt></ruby>”。
|
||||
* 打开“<ruby>应用程序菜单<rt>Application Menu</rt></rt></ruby> > <ruby>设置<rt>Settings</rt></ruby> > <ruby>窗口管理器调整<rt>Window Manager tweaks</rt></ruby>”，在“<ruby>合成器<rt>Compositor</rt></ruby>”标签下，取消勾选“<ruby>在停靠窗口下显示阴影<rt>Show shadows under dock windows</rt></ruby>”。
|
||||
|
||||
现在你应该在桌面上看到一个 “ThemeTwister” 图标，打开该应用。这个应用为你提供了改变主题的选项，如下图所示。
|
||||
|
||||
![Changing theme using ThemeTwister tool][10]
|
||||
|
||||
选择一个主题并点击相应的按钮。每次你改变或应用一个主题时，该脚本都会要求你注销。所以在改变主题之前，请确保你关闭所有的程序。
|
||||
|
||||
### 如何卸载
|
||||
|
||||
如果你完成后想卸载，那么打开终端，运行下面的 shell 脚本。
|
||||
|
||||
```
|
||||
sh /usr/share/ThemeSwitcher/uninstall.sh
|
||||
```
|
||||
|
||||
上述脚本只卸载了 Twister UI 组件，并没有卸载 Steam、Lutris 等。所以如果你想卸载，请使用软件管理器来卸载它们。
|
||||
|
||||
如果你在卸载后做一次重启，那是最好的。
|
||||
|
||||
### 评测和性能
|
||||
|
||||
根据 Pi 实验室的说明，该定制应该不会消耗太多的额外内存。这也是事实。
|
||||
|
||||
该定制对桌面性能影响不大。当我在 Linux Mint Xfce 版的空闲模式下运行一到两项定制时，它消耗了大约 740MB 的内存，CPU 大约 2% 到 3%。这本身就令人印象深刻。使用它的唯一代价是额外的磁盘空间。
|
||||
|
||||
![Resource Usage in Linux Mint with Twister UI][11]
|
||||
|
||||
主题切换器非常好，完美地改变了主题，没有意外和错误。
|
||||
|
||||
总的来说，整个过程是无痛的，按照其设计进行得很好。
|
||||
|
||||
### 总结
|
||||
|
||||
你可以下载单独的主题图标，改变设置，手动配置你的 Linux 发行版，使其看起来像 Windows 或 macOS。这需要很多时间，有时对新用户来说也很困难。考虑到这一点，我认为这种新方法可以节省时间，对每个人来说都非常容易。你只需点击一个按钮，就可以得到所有需要的增强模组。
|
||||
|
||||
总有一种争论，为什么 Linux 需要看起来像 Windows 或 macOS。但老年人可能不太熟悉电脑，不过他们记得 Windows 的颜色和图标。他们可以使用这种简单的修改来适应 Linux，而不会有任何麻烦。
|
||||
|
||||
总的来说，这是一个来自 Pi 实验室的优秀项目，可以帮助到全世界的许多用户。
|
||||
|
||||
那么，你对这个项目有什么看法？请在下面的评论栏里告诉我。

#### 2、elementary OS
|
||||
|
||||
elementary OS 是基于 Ubuntu 长期稳定支持（LTS）发行版中最美观的一个。它使用吸引人的 Pantheon 桌面环境，其外观和使用体验受到了 macOS 的启发。
|
||||
|
||||
elementary OS 非常适合从 macOS 进入 Linux 世界的新用户，因为他们会发现许多熟悉的东西，比如手势和窗口样式。
|
||||
|
||||
但是，elementary OS 很多地方不能通过设置菜单进行定制，只能依靠外部脚本命令来进一步定制。不过系统默认桌面就已经十分美观了，能满足大部分人的需求。

![Puppy Linux – one of the best lightweight Linux Distribution in 2022][4]
|
||||
|
||||
这个 Linux 发行版与 Ubuntu 的 LTS 版本的二进制文件是兼容的；其最新的版本基于 Ubuntu 20.04 LTS。因为 Ubuntu 放弃了 32 位的支持，所以其最新版本也放弃了 32 位的支持。
|
||||
|
||||
Puppy Linux 非常适合于旧计算机、上网本以及内存小于 1GB 的机器。在其核心，运行着超快速的 JWM（Jow’s Window Manager）。Puppy 软件包管理器支持 .deb 、.rpm 及其原生的 PET 软件包。

|
||||
|
||||
#### 3、BunsenLabs Linux
|
||||
|
||||
在这份列表中的第三款轻量级 Linux 发行版是 BunsenLabs Linux ，它是 Crunchbang 项目的继任者。BunsenLabs Linux 基于 Debian 稳定分支，为你的低端系统带来了现代应用。这个发行版为低端硬件提供了一个 32 位版本的镜像，并为你的常规硬件提供一个标准的 64 位版本的镜像。在其核心，BunsenLabds 由一个预配置的 OpenBox 窗口管理器所驱动，并带有令人惊艳的 tint2 面板、预配置的 Conky 和 jgmenu 。
|
||||
|
||||
![BunsenLabs Linux][5]
|
||||
|
||||
这是一款针对旧硬件的、设计良好、速度超快、稳定且外观漂亮的发行版。
|
||||
|
||||
特点：
|
||||
|
||||
* 基于 Debian 稳定分支
|
||||
* Openbox 窗口管理器，附带 tint2 面板、Conky 和 jgmenu
|
||||
* 提供 32 位安装程序
|
||||
* 可以通过官方论坛获取帮助和支持
|
||||
|
||||
> **[下载 BunsenLabs Linux][6]**
|
||||
|
||||
#### 4、Lubuntu
|
||||
|
||||
Lubuntu 是一款著名的轻量级 Linux 发行版。它是一款官方的 Ubuntu Linux 衍生版本，其特点是使用轻量级 LxQt 桌面环境。Lubuntu 在给予你现代的 Ubuntu Linux 软件包和技术的同时，也针对你的低端硬件提供了 LxQt 桌面环境。尽管与这份列表中的其它的发行版相比，它可能需要更多的一些系统资源，但是对于旧硬件来说，它仍然是一个适合的 Linux 发行版。
|
||||
|
||||
![Lubuntu][7]
|
||||
|
||||
如果你需要一款稳定且开箱即用的适中量级的 Linux 发行版，那么，请选择 Lubuntu 。
|
||||
|
||||
> **[下载 Lubuntu][8]**
|
||||
|
||||
#### 5、Absolute Linux
|
||||
|
||||
第五款轻量级 Linux 发行版是 Absolute Linux ，它基于 Slackware Linux 。这个发行版在其安装程序镜像中打包了所有日常需要的应用程序，以便你可以获得一款开箱即用的发行版。Absolute Linux 以使用 IceWM 和 ROX 桌面环境为特色，在旧硬件中使用它们时，能为你带来极致的速度。它不使用 systemd，这为它提供了比其他发行版更多的优势。
|
||||
|
||||
![Absolute Linux][9]
|
||||
|
||||
特点：
|
||||
|
||||
* 基于 Slackware
|
||||
* 不使用 systemd
|
||||
* 打包了必要的软件包
|
||||
* IceWM 桌面环境、Slapt-get 软件包管理器
|
||||
|
||||
> **[下载 Absolute Linux][10]**
|
||||
|
||||
#### 6、antiX Linux
|
||||
|
||||
我们想重点推荐的另一款轻量级 Linux 发行版是 antiX Linux 。antiX Linux 基于 Debian 稳定分支，并带来一些吸引人的功能。在其核心，它使用 IceWM、Fluxbox 和 ROX 桌面环境，给予你一种优秀而快速的桌面体验。它完全没有使用 systemd，而是使用 sysVinit 和 runit 系统。antiX Linux 还为你提供了 32 位安装程序，并且还四个变体 – 完全版、核心版、基本版以及网络版，以满足不同的实际使用情况。
|
||||
|
||||
![antiX Linux][11]
|
||||
|
||||
特点：
|
||||
|
||||
* 基于 Debian 稳定分支
|
||||
* 32 位安装程序
|
||||
* 不使用 systemd
|
||||
* IceWM 及其它的窗口管理器衍生特色版本
|
||||
|
||||
> **[下载 antiX Linux][12]**
|
||||
|
||||
#### 7、LXLE
|
||||
|
||||
LXLE Linux 是 Lubuntu LTS 的一个变体，使用 LXDE 桌面环境而非 LXQt 桌面环境。其对应用程序、安装程序以及其它功能的选择，使其成针对旧硬件的一款完美的发行版。它基于稳定的 Ubuntu LTS 版本，是以快速的 LXDE 桌面环境来复兴你的旧系统的理想选择。
|
||||
|
||||
![LXLE Linux][13]
|
||||
|
||||
然而，就我个人见解，我感觉 LXQt 比 LXDE 稍快一点。好吧，这种反馈可能是因人而异的，对你来说可能是不同的。现在，没有多少 Linux 发行版能向你提供 LXDE 桌面环境的衍生版本。因此，对于日常使用的来说，它可能是一款独特的轻量级的 Linux 发行版。
|
||||
|
||||
> **[下载 LXLE][14]**
|
||||
|
||||
#### 8、Porteus Linux
|
||||
|
||||
Porteus Linux 是 Slackware Linux 的翻版，以旧的 KDE 4.0+ 桌面环境（KDE Plasma 系列之前的版本）为特色。这款超快的 Linux 发行版非常适合你的古董硬件，因为它基于最先进的 Slackware ，并且向你提供了 32 位版本。这款发行版可以从现场 USB/CD 或任意可启动介质运行，安装程序仅 300 MB 大小。
|
||||
|
||||
如果你喜欢老款 KDE（像我一样！）和 Slackware 的简单易用，对你来说这将会是一个完美的发行版，甚至针对你的新硬件也是一样。
|
||||
|
||||
![Porteus Linux][16]
|
||||
|
||||
> **[下载 Porteus Linux][17]**
|
||||
|
||||
#### 9、Q4OS
|
||||
|
||||
Q4OS 是这份列表中的一款独特的 Linux 发行版。它针对的是现今已经过时的旧 Windows 系统。曾经很多运行过 Windows XP 和 Windows 7 的老式 PC，它们不再能很好地运行 Windows 和一些现代的 Linux 发行版，因为现代的操作系统要求更多的计算能力和资源。
|
||||
|
||||
Q4OS 针对这些实际使用实例，给予你一款精心设计的 Linux 发行版，附带有 32 位安装程序、 Windows 安装程序、Trinity 桌面环境，以及预制的 Windows 主题等。
|
||||
|
||||
![Q4OS][18]
|
||||
|
||||
> **[下载 Q4OS][19]**
|
||||
|
||||
#### 10、MX Linux
|
||||
|
||||
在这份列表中的最后一款 Linux 发行版是著名的 MX Linux ，它凭借其特色和独特性在当今时代打响了知名度。然而，我都怀疑是否应该将 MX Linux 列为轻量级。因为在我看来，如果你考虑到它的 KDE Plasma 衍生版本，它应该是中等量级的 Linux 发行版。
|
||||
|
||||
![MX Linux][20]
|
||||
|
||||
不管怎么说，它的一些特色使其成为一款轻量级 Linux 发行版的完美候选版本。MX Linux 基于 Debian 稳定分支，并使用了 antiX 组件创建。它的特点是有自己的用于更多工作流的 MX Linux 原生应用程序。你可以使用 KDE Plasma 、Xfce 和 Fluxbox 作为桌面环境。
|
||||
|
||||
> **[下载 MX Linux][21]**
|
||||
|
||||
### 总结
|
||||
|
||||
如果你仔细观察就会发现，我们在这里所列出的大多数的轻量级 Linux 发行版都基于 Debian Linux 的。它是真正的 “通用操作系统”。现代的 Linux 桌面环境，像 GNOME 40+ 、KDE Plasma 和 Systemd 初始化系统，已经不再兼容旧硬件。此外，随着技术的进步，引入了更多的软件复杂性，需要更高端的硬件。
|
||||
|
||||
尽管如此，我希望你可以从这份列表中找到一些为你的旧笔记本电脑或 PC 选择轻量级 Linux 发行版的灵感。每一款发行版都提供了不同的体验，但是都有共同的目标：让你的旧硬件恢复活力。所以，任君采撷。
|
||||
|
||||
感谢阅读，请发表你的评论。如果这对你有所帮助，那怕说声“谢谢”也是好的。

雷蛇与 Lambda 联手推出用于深度学习的 Linux 笔记本电脑
|
||||
======
|
||||
|
||||
> 雷蛇与一家专注于深度学习的硬件公司合作，以时尚的外形、昂贵的价格提供了最新和最伟大的产品。
|
||||
|
||||
|
||||
|
||||
<ruby>雷蛇<rt>Razer</rt></ruby> 以其游戏外设和硬件而闻名。
|
||||
|
||||
另一方面，Lambda 提供配备了他们的软件栈的工作站、服务器和 GPU 集群，以尽可能方便地促进深度学习。
|
||||
|
||||
他们合作推出了一款外观时尚的现代笔记本电脑（由 Ubuntu 20.04 驱动），专为随时随地的深度学习而设计。
|
||||
|
||||
它不同于 [其他 Linux 笔记本电脑][1]。
|
||||
|
||||
顺便说一句，深度学习是一种机器学习，你通过实例教给计算机学会类似人类处理信息的方式。你可以查看 [维基百科][2] 以了解更多细节。
|
||||
|
||||
### Tensorbook：深度学习笔记本电脑
|
||||
|
||||
[![][3]](https://youtu.be/wMh6Dhq7P_Q)
|
||||
|
||||
Tensorbook 是一款由 Linux 驱动的笔记本电脑，具有最先进的规格，可以帮助你在任何地方高效地进行深度学习训练/开发。而且，Lambda 的软件栈支持各种工具，只需一个命令就能方便地更新 PyTorch、Tensorflow、CUDA 等。
|
||||
|
||||
当然，这个名字并不令人意外，因为<ruby>张量<rt>Tensor</rt></ruby>核心有助于加快机器学习训练/过程。
|
||||
|
||||
![][4]
|
||||
|
||||
雷蛇没有在这台笔记本电脑上添加任何他们惯用的标志性图案，比如绿色的点缀/颜色、标志或 RGB 元素。好吧，毕竟这是为深度学习而定制的。所以，它不太浮华是公平的。
|
||||
|
||||
你只能在盖子上找到 Lambda 主要标志，在屏幕的底边框上找到 Razer x Lambda 的文字。而且，紫色的风格贯穿始终，Lambda 在这里主导了其品牌宣传。
|
||||
|
||||
这款笔记本电脑的规格涉及：
|
||||
|
||||
* GPU：GeForce RTX 3080 Max-Q 16 GB VRAM
|
||||
* CPU：Intel i7-11800H
|
||||
* 内存：64 GB 3200 MHz DDR4
|
||||
* 存储：2 TB NVMe PCIe 4.0
|
||||
* 显示：165 Hz 1440p 15.6 英寸
|
||||
|
||||
除了可靠的核心配置外，连接选项包括：
|
||||
|
||||
* 3 个 USB 3.2 Gen 2 Type-A 端口
|
||||
* 1 x HDMI 2.1
|
||||
* 1 个 UHS-III SD 卡阅读器
|
||||
* 3.5 毫米耳机/麦克风插孔
|
||||
* 2 个雷电 4 端口
|
||||
* Wi-Fi 6E
|
||||
* 蓝牙 5.2
|
||||
|
||||
毋庸置疑，这款笔记本电脑是一个时尚的“动力工厂”，将这些组件容纳于其中。
|
||||
|
||||
无论你是专业人士还是初学者，RTX 3080 GPU 应该有足够的能力来帮助你完成深度学习任务。
|
||||
|
||||
当然，它不是为游戏而设计的，但以你所拥有的配置以及高刷新率的屏幕，你可以在需要的时候在上面舒适地玩游戏。
|
||||
|
||||
![][5]
|
||||
|
||||
其机器学习训练基准声称，它远远领先于 M1 Max 芯片。
|
||||
|
||||
因此，你在训练模型方面不会有任何问题。
|
||||
|
||||
### 定价和可用性
|
||||
|
||||
这是一款高端产品，所以价格标签也一样高端，起价为 **3499 美元**。你可以为企业环境定制它，以便安装上 Windows 10 和 Ubuntu。
|
||||
|
||||
如果你支付额外的费用，还可以获得延长保修和高级支持。
|
||||

LibreWolf vs Firefox：谁是真的隐私英雄
|
||||
======
|
||||
|
||||
|
||||
|
||||
Firefox 是最好的跨平台 [开源网页浏览器][1] 之一。
|
||||
|
||||
更不用说，它是那些基于 Chromium 的浏览器的唯一可行的替代品（也许？）
|
||||
|
||||
LibreWolf 是另一个有趣的选择，它最初是 Firefox 浏览器的一个复刻，试图比 Firefox 浏览器做得更好，以增强开箱即用的隐私/安全性。
|
||||
|
||||
但是，选择 LibreWolf 而不是 Firefox 真的有用吗？有哪些不同之处？让我们来看一看。
|
||||
|
||||
### 用户界面
|
||||
|
||||
鉴于 [LibreWolf][2] 是 Firefox 的一个复刻，其用户界面是相同的，只是有一些细微的变化。
|
||||
|
||||
![Firefox UI][3]
|
||||
|
||||
例如，它在书签菜单中没有到 Firefox 网站的链接，并且去除了 “<ruby>添加到 Pocket<rt>Add to Pocket</rt></ruby>” 按钮。
|
||||
|
||||
取而代之的是，你可以在地址栏的右边找到一个扩展的图标和下载管理器。
|
||||
|
||||
![LibreWolf UI][4]
|
||||
|
||||
是的，你不再需要前往菜单来访问下载的内容。
|
||||
|
||||
如果你认为 Firefox 中的额外功能令人烦恼，那么 LibreWolf 应该是一种干净的体验。
|
||||
|
||||
### 搜索供应商
|
||||
|
||||
默认情况下，Firefox 使用谷歌作为其搜索引擎，因为它们是官方合作伙伴，也就是说，谷歌付费成为了默认搜索引擎。
|
||||
|
||||
![][5]
|
||||
|
||||
虽然你可以很轻松地将默认的搜索供应商改为 DuckDuckGo、Startpage 或其他任何东西，但默认的搜索供应商对大多数用户来说仍然很重要。
|
||||
|
||||
而对于 LibreWolf，它的默认的搜索引擎是 DuckDuckGo。众所周知，它是最好的尊重隐私的搜索引擎之一。
|
||||
|
||||
![][6]
|
||||
|
||||
应该注意的是，注重隐私的搜索引擎在某些使用情况下可能不如谷歌好。因此，如果搜索引擎的选择对你来说并不是个问题，Firefox 浏览器可以说是很好。
|
||||
|
||||
但是，如果你想对自己的搜索历史保密，LibreWolf 的默认搜索供应商肯定是一个更好的选择。
|
||||
|
||||
### 强化隐私
|
||||
|
||||
Mozilla Firefox 具有令人难以置信的可定制性。如果你想付出努力，你可以在 Firefox 上增强你的数字隐私。
|
||||
|
||||
然而，如果你想避免投入大量时间来调整 Firefox 的体验，LibreWolf 可能是一个不错的选择。
|
||||
|
||||
LibreWolf 具有一些开箱即用的最佳设置，以确保你摆脱网上的跟踪器，以获得安全的在线体验。
|
||||
|
||||
例如，它的默认带有 UBlock 内容拦截器，以消除跟踪你在线活动的跟踪器/脚本。其默认的搜索引擎是 DuckDuckGo，在一定程度上也有帮助。
|
||||
|
||||
![][7]
|
||||
|
||||
此外，LibreWolf 还启用了 Firefox 增强跟踪保护的严格模式。换句话说，它可以积极地阻止跟踪器，这可能会导致一些网页不能像预期那样工作。
|
||||
|
||||
![][8]
|
||||
|
||||
虽然 LibreWolf 建议不要改变这些设置，但如果你发现在此设置下网页被破坏，你可以选择使用 Firefox。
|
||||
|
||||
Firefox 使用启用的基本保护来摆脱常见的追踪器，而不会破坏网页的用户体验。
|
||||
|
||||
除了这些设置外，LibreWolf 还默认在退出时删除 Cookie 和网站数据。如果你想继续登录网站并迅速恢复你的浏览会话，这可能会很烦人。
|
||||
|
||||
对于 Firefox，它确实具有相同的选项，但它默认情况下仍然是禁用的。因此，如果你想避免调整内置设置以获得方便的体验，你应该选择 Firefox。
|
||||
|
||||
![][9]
|
||||
|
||||
难怪 Firefox 仍然是 [Linux 的最佳浏览器][10] 之一。相比增强隐私，大多数用户更喜欢方便，同时还能跨平台使用浏览器。
|
||||
|
||||
### 谷歌安全浏览
|
||||
|
||||
“<ruby>谷歌安全浏览<rt>Google Safe Browsing</rt></ruby>”是一项有用的服务，可以警告、标记可疑网站的恶意活动。
|
||||
|
||||
大多数浏览器使用它来实现安全的用户体验。你不需要成为发现钓鱼/恶意软件网站的专家，谷歌安全浏览可以帮助你发现它们。
|
||||
|
||||
Mozilla Firefox 使用它的另一个名字 “<ruby>钓鱼保护<rt>Phishing Protection</rt></ruby>”，它是默认启用的。
|
||||
|
||||
然而，在 LibreWolf 中，“谷歌安全浏览”服务默认是禁用的，以避免连接到谷歌服务。你可以启用它，但它不是用户通常在设置浏览器时会注意到的东西。
|
||||
|
||||
![][11]
|
||||
|
||||
因此，如果你在避免恶意网站方面需要更多帮助，Firefox 应该是一个很好的开箱即用的解决方案。如果你对这些很清楚，你可以使用 LibreWolf，并在需要时启用该设置。
|
||||
|
||||
### 附加功能
|
||||
|
||||
LibreWolf 可以摆脱 Firefox 上的任何附加产品。
|
||||
|
||||
例如，默认情况下，LibreWolf 与 Mozilla 服务器没有任何连接。这也意味着 LibreWolf 摆脱了遥测。它所反映的一些变化包括：
|
||||
|
||||
* LibreWolf 中没有同步/签到功能。
|
||||
* 没有 “添加到 Pocket” 的按钮
|
||||
* 你不会在扩展页面上加载 Mozilla 的附加组件/主题。
|
||||
|
||||
![][12]
|
||||
|
||||
如果你想使用 Mozilla 帐户来同步你的历史记录/书签和浏览器数据，Firefox 是最好的选择。如果你需要，还有 Firefox VPN。
|
||||
|
||||
![][13]
|
||||
|
||||
但是，如果你不信任任何 Mozilla 服务并希望在你的浏览器上切断与它们的任何连接，那么 LibreWolf 就是你的朋友。
|
||||
|
||||
### 跨平台支持
|
||||
|
||||
Firefox 可用于 Android 和 iOS，并且适用于各种屏幕尺寸和设备。
|
||||
|
||||
不幸的是，LibreWolf 仅限于 macOS、Windows、OpenBSD 和 Linux 等桌面平台。
|
||||
|
||||
### 基于社区 vs 由组织支持
|
||||
|
||||
[LibreWolf][14] 是一个由社区支持的项目，由一些热情的贡献者维护，旨在促进隐私、安全和用户自由。
|
||||
|
||||
如果你更喜欢 LibreWolf 提供的产品，那么使用它应该不是问题。即使是一个小团队，他们也会关注最新的 Firefox 版本并尽快推送更新。
|
||||
|
||||
相比之下，Mozilla 基金会是一个更大的组织，并且一直在树立非凡的榜样来促进可定制性、隐私和安全性。
|
||||
|
||||
Firefox 会比 LibreWolf 更快地收到更新，如果你担心浏览器的安全性，这是一个重要方面。
|
||||
|
||||
Firefox 属于一个大组织并没有严重的缺点，但是 Mozilla 为其用户提出的未来可能会有一些你可能不喜欢的决定（或变化）。
|
||||
|
||||
但是，LibreWolf 作为一个社区项目，会优先考虑用户偏好。
|
||||
|
||||
### 总结
|
||||
|
||||
如果方便是你在意的，你需要同步/登录账户功能、Mozilla 的特定功能，以及基本的隐私保护，Mozilla Firefox 应该更适合你。
|
||||
|
||||
如果你不想要开箱即用的云同步功能、附加功能和以隐私为中心的核心设置，LibreWolf 将是完美的解决方案。
|
||||
|
||||
在性能方面，两者都应该提供类似的体验。由于某种原因，基准测试（Basemark 3.0、Speedometer 2.0）不适用于 LibreWolf，因此我没有提供任何性能比较图表。
|
||||
|
||||
我更喜欢使用 Firefox，因为我确实需要基于帐户的同步的便利性，而不需要积极的阻止功能。然而，对于那些想要放弃 Firefox 或者只是想尝试一些专注于用户自由和隐私的东西的人来说，LibreWolf 是一个可靠的选择。
|

使用 Fedora ARM 服务器来做 3-2-1 备份计划
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
Fedora 服务器版操作系统可以运行在类似树莓派的单板计算机（SBC）上。这篇文章针对的用户是想要充分利用实体服务器系统，并使用类似 Cockpit 的内置工具进行数据备份和个人数据的恢复。这里描述了备份的 3 个阶段。
|
||||
|
||||
### 必要的准备
|
||||
|
||||
想要使用本指南，你所需要的是一个运行着的 Fedora Linux 工作站和以下的项目：
|
||||
|
||||
* 你应该阅读、理解和实践 Fedora 文档中 [服务器安装][4] 和 [管理][5] 的要求
|
||||
* 一块用来测试 Fedora Linux 的 SBC（单板计算机）。在这里查看 [硬件需求][6]
|
||||
* [Fedora ARM][7] [服务器][7] 原始镜像 & ARM 镜像安装器
|
||||
* SD 存储卡（64 GB / Class 10）和 SSD 设备两选一
|
||||
* 以太网 / DHCP 预留 IP 地址或者静态 IP 地址
|
||||
* 提供了 ssh 密钥的 Linux 客户端工作站
|
||||
* 选择云存储服务
|
||||
* 有额外可用的 Linux 工作站
|
||||
|
||||
对于这套环境，在写这篇文章的时候，由于成本和可用性的原因，我选择树莓派 3B+/4B+ （其中一个用来热切换）。当使用 Cockpit 远程连接树莓派服务器时，你可以将树莓派放到路由器附近以便设置。
|
||||
|
||||
### 加强服务器的安全
|
||||
|
||||
在 SBC 完成服务器的安装和管理后，用 firewalld 加强服务器的安全是一个好的做法。
|
||||
|
||||
连接存储设备到服务器之前，一旦服务器在线你必须设置好防火墙。firewalld 是基于区域的防火墙。在依照 Fedora 文档完成安装和管理指南之后，创建一个名为 `FedoraServer` 的预定义区域。
|
||||
|
||||
#### firewalld 里的富规则
|
||||
|
||||
<ruby>富规则<rt>rich rule</rt></ruby>用来阻止或者允许一个特定的 IP 地址或者地址段。下面这条规则只从（客户端工作站）注册的 IP 地址接受 SSH 连接，并断开其它的连接。在 Cockpit 终端或者客户端工作站终端运行命令是通过 ssh 来连接到服务器的。
|
||||
|
||||
```
|
||||
firewall-cmd --add-rich-rule='rule family=ipv4 source address=<registered_ip_address>/24 service name=ssh log prefix="SSH Logs" level="notice" accept'
|
||||
```
|
||||
|
||||
#### 拒绝所有主机的 ping 请求
|
||||
|
||||
使用这个命令来设置 icmp 拒绝，并且不允许 ping 请求：
|
||||
|
||||
```
|
||||
firewall-cmd --add-rich-rule='rule protocol value=icmp reject'
|
||||
```
|
||||
|
||||
要进行其它防火墙控制，比如管理端口和区域，请查阅以下链接。请注意错配防火墙可能会使安全出现漏洞受到攻击。
|
||||
|
||||
> **[在 Cockpit 中管理防火墙][8]**
|
||||
|
||||
> **[firewalld 规则][9]**
|
||||
|
||||
### 配置文件服务器的存储
|
||||
|
||||
下一步是连接存储设备到 SBC，然后使用 Cockpit 对新插入的存储设备进行分区。使用 Cockpit 的图形化服务器管理界面，管理一个家庭实验室（可以是一个或者多个服务器）比之前更加简单。Fedora Linux 服务器标准提供了 Cockpit。
|
||||
|
||||
在这个阶段，一个通过 SBC 的 USB 插口接电的 SSD 设备无需额外电源供给就可以工作。
|
||||
|
||||
* 将存储设备连接到 SBC 的 USB 接口
|
||||
* 运行之后（按上面的“必要的准备”所设置的那样），然后在你的客户端工作站浏览器上访问 **机器的 IP 地址:9090**
|
||||
* 登录进 Cockpit 之后，点击 Cockpit 页面顶部的“<ruby>打开管理访问权限<rt>Turn on administrative access</rt></ruby>”
|
||||
* 点击左边面板的 “<ruby>存储<rt>Storage</rt></ruby>” 按钮
|
||||
* 选择下面显示的 “<ruby>驱动器<rt>Drives</rt></ruby>”，然后分区并格式化一个空白的存储设备
|
||||
![Cockpit Storage management][10]
|
||||
* 在选定的存储设备这个界面上，创建一个新的分区表或者格式化并创建新的分区。当初始化磁盘的时候，在 “<ruby>Partitioning<rt>分区</rt></ruby>” 类型选项上，选择 “GPT 分区表”
|
||||
* 选择一个文件系统类型，这里选择 “EXT4” 。这对于一个限制 I/O 能力（比如 USB 2.0 接口）和限制带宽（小于 200MB/s）的设备是适合的
|
||||
![Create a partition in Cockpit][11]
|
||||
* 要在设备上创建单个占据整个存储空间的分区，指定它的挂载点，比如 `/media` 然后点击 “<ruby>确定<rt>Ok</rt></ruby>” 。
|
||||
* 点击 “<ruby>Create partition<rt>创建分区</rt></ruby>”，创建一个挂载点为 `/media` 的新分区。
|
||||
|
||||
### 创建备份和恢复备份
|
||||
|
||||
备份很少是一刀切的。这里有一些选择比如数据备份在哪里，备份数据的步骤，验证一些自动化，并确定怎样来恢复备份了的数据。
|
||||
|
||||
![Backup workflow – version 1.0][12]
|
||||
|
||||
#### 备份 1. 用 rsync 从客户端远程同步到文件服务器（树莓派）
|
||||
|
||||
这个传输用到的命令是：
|
||||
|
||||
```
|
||||
rsync -azP ~/source syncuser@host1:/destination
|
||||
```
|
||||
|
||||
参数:
|
||||
- `-a`/`--archive`：归档
|
||||
- `-z`/`--compress`：压缩
|
||||
- `-P`/`--progress`：显示进度
|
||||
|
||||
要使用更多的选项运行 `rsync`，可以设置以下的选项：
|
||||
|
||||
- `--inplace`：直接替换来更新目标文档
|
||||
- `--append`：追加数据到较短的文档中
|
||||
|
||||
在将文档备份到存储空间之前，源端文档的文件重复消除和压缩是减少备份数据容量最有效的方式。
|
||||
|
||||
每天工作结束，我会手动运行这个。一旦我设置了云备份工作流，自动化脚本是一个优势。
|
||||
|
||||
关于 `rsync` 的详细信息，请在 [这里][13] 访问 Fedora 杂志的文章。
|
||||
|
||||
#### 备份 2. 使用 rysnc 从文件服务器远程同步到主要的云存储上
|
||||
|
||||
选择云存储是考虑的因素；
|
||||
|
||||
* 成本：上传、存储空间和下载费用
|
||||
* 支持 `rsync`、`sftp`
|
||||
* 数据冗余（RAID 10 或者运行中的数据中心冗余计划）
|
||||
* 快照
|
||||
|
||||
符合这些云存储标准之一的就是 Hetzner 托管的 Nextcloud– [存储盒子][14]。你不会受到供应商限制，可以自由切换而没有退出惩罚。
|
||||
|
||||
##### 在文件服务器上生成 SSH 密钥并创建授权密钥文件
|
||||
|
||||
使用 `ssh-keygen` 命令为文件服务器和云存储生成一对新的 SSH 密钥对。
|
||||
|
||||
```
|
||||
ssh-keygen
|
||||
Generating public/private rsa key pair.
|
||||
Enter file in which to save the key . . .
|
||||
```
|
||||
|
||||
插入要求的 SSH 公钥到新的本地授权密钥文件中。
|
||||
|
||||
```
|
||||
cat .ssh/id_rsa.pub >> storagebox_authorized_keys
|
||||
```
|
||||
|
||||
##### 传输密钥文件到云存储
|
||||
|
||||
下一步就是上传生成了的授权密钥文件到存储盒子。要做这些，先用 700 权限创建 `.ssh` 目录，然后用 SSH 公钥创建授权文件并赋予 600 权限。运行以下命令。
|
||||
|
||||
```
|
||||
echo -e "mkdir .ssh \n chmod 700 .ssh \n put storagebox_authorized_keys .ssh/authorized_keys \n chmod 600 .ssh/authorized_keys" | sftp <username>@<username>.your-storagebox.de
|
||||
```
|
||||
|
||||
##### 通过 ssh 使用 rsync
|
||||
|
||||
使用 `rsync` 同步你的文件目录当前状态到存储盒子。
|
||||
|
||||
```
|
||||
rsync --progress -e 'ssh -p23' --recursive <local_directory> <username>@<username>.your-storagebox.de:<target_directory>
|
||||
```
|
||||
|
||||
这个过程被叫做推送操作，因为它 “推送” 本地系统的一个目录到一个远程的系统中去。
|
||||
|
||||
##### 从云存储中恢复目录
|
||||
|
||||
要从存储盒子恢复目录，转换到这个目录：
|
||||
|
||||
```
|
||||
rsync --progress -e 'ssh -p23' --recursive <username>@<username>.your-storagebox.de:<remote_directory> <local_directory>
|
||||
```
|
||||
|
||||
#### 备份 3. 客户端备份到第二个云储存
|
||||
|
||||
[Deja Dup][15] 是 Fedora 软件仓库中为 Fedora 工作站提供快速备份解决方案的工具。它拥有 GPG 加密、计划任务、文件包含（哪个目录要备份）等功能。
|
||||
|
||||
![Backing up to the secondary cloud][16]
|
||||
|
||||
![Restoring files from cloud storage][17]
|
||||
|
||||
### 归档个人数据
|
||||
|
||||
不是所有数据都需要 3-2-1 备份策略。这就是个人数据共享。我将一台拥有 1TB 硬盘的笔记本作为我个人数据的档案（家庭照片）。
|
||||
|
||||
转到设置中的 “<ruby>共享<rt>Sharing</rt></ruby>” （在我的例子中是 GNOME 文件管理器）并切换滑块以启用共享。
|
||||
|
||||
![][18]
|
||||
|
||||
打开 “<ruby>文件共享<rt>file sharing</rt></ruby>”，“<ruby>网络<rt>Networks</rt></ruby>” 和 “<ruby>需要的密码<rt>Required password</rt></ruby>”，允许你使用 WebDAV 协议在你的本地网络上分享你的公共文件夹给其它的工作站。
|
||||
|
||||
![][19]
|
||||
|
||||
### 准备回滚选项
|
||||
|
||||
未测试的备份并不比完全没有备份好。我在家庭实验室环境中使用 “热切换” 方法来避免像频繁的断电或者液体损坏的情况发生。然而，我的建议方案远没有达到灾难恢复计划或企业 IT 中的自动故障修复。
|
||||
|
||||
* 定期运行文件恢复操作
|
||||
* 备份 ssh/GPG 密钥到一个额外的存储设备中
|
||||
* 复制一个 Fedora ARM 服务器的原始镜像到一个 SD 卡中
|
||||
* 在主云存储中保持全备份的快照
|
||||
* 自动化备份过程最小化减少人为错误或者疏忽
|
||||
|
||||
### 使用 Cockpit 追踪活动并解决问题
|
||||
|
||||
当你的项目在成长时，你所管理的服务器数量也在增长。在 Cockpit 中追踪活动和警告可以减轻你的管理负担。你可以使用 Cockpit 的图形化界面的三种方法来归档这些。
|
||||
|
||||
#### SELinux 菜单
|
||||
|
||||
怎样诊断网络问题，找到日志并在 Cockpit 中解决问题：
|
||||
|
||||
* 去 SELinux 中检查日志
|
||||
* 检查“<ruby>解决方案详细信息<rt>solution details</rt></ruby>”
|
||||
* 当必要时，选择 “<ruby>应用这个方案<rt>Apply this solution</rt></ruby>”
|
||||
* 如果必要，查看自动化脚本并运行它
|
||||
|
||||
![SELinux logs][20]
|
||||
|
||||
#### 网络或者存储日志
|
||||
|
||||
服务器日志会跟踪 CPU 负载、内存使用、网络活动、存储性能和系统日志关联的详细指标。日志会组织在网络面板或者存储面板里显示。
|
||||
|
||||
![Storage logs in Cockpit][21]
|
||||
|
||||
#### 软件更新
|
||||
|
||||
在预设的时间和频率下，Cockpit 可以帮助进行安全更新。当你需要时，你可以运行所有的更新。
|
||||
|
||||

|
||||
|
||||
恭喜你在 Fedora ARM 服务器版本上搭建了一个文件/备份服务器。

埃隆·马斯克认为推特的算法应该开源
|
||||
======
|
||||
|
||||
> 埃隆·马斯克希望推特开源他们的算法。这会促进言论自由吗？以下是他的说法。
|
||||
|
||||
|
||||
|
||||
没错，埃隆·马斯克又搞了一个大新闻，这已经算是他的日常操作了。
|
||||
|
||||
然而，这一次的新闻非常有趣。他提出了要以大约 **430 亿美元** 收购推特。
|
||||
|
||||
从技术上讲，他的报价远远超过了市场价格，这也就是为什么许多媒体称他这是在试图“恶意收购”。
|
||||
|
||||
考虑到这个激进的报价，我们还不确定这次收购是否会成功。不过，在一次 TED 演讲中，埃隆·马斯克还分享了他对于推特应该如何推动言论自由的一些想法。
|
||||
|
||||
### 推特的算法应该开源
|
||||
|
||||
埃隆·马斯克认为，推特应该将算法开源，以促进平台的透明度。
|
||||
|
||||
当然，推特作为一个平台，目前仍在爆炸式发展，很难预测。推特团队在某些事情上也会采取果断行动，不管用户认为它是否正确。
|
||||
|
||||
虽然推特的内部决定在纸面上看起来很好，但这种没有透明度的大规模平台总是会存在问题的。
|
||||
|
||||
因此，埃隆·马斯克有一个观点：无论你是否认同或相信推特的决定，透明/开源只会有助于加强现有的价值观。
|
||||
|
||||
嗯，难怪我们喜欢开源。
|
||||
|
||||
这里引用他的原话：
|
||||
|
||||
> “因此，我认为推特应该做的事情之一就是开源它的算法，所有推文的修改都应该是透明的，任何人都可以看到这个修改，哪怕是加粗一段文字或是取消加粗它。这样一来，幕后操纵将不复存在，无论是算法还是人工。”
|
||||
|
||||
另一方面，当我们把推特当作一个某种程度上的开源平台来谈论时，我不由自主地想到了 [Mastodon][7]。你也可以在 [Mastodon][8] 上找到我们，如果你还没有用过它的话。
|
||||
|
||||
诚然，推特有很大的增长潜力，无论好坏，它都在不断扩张。但是，开源理念能否帮助这个平台？我个人认为可以，但这是一个巨大的变革，不能指望一夜之间就能实现。
|
||||
|
||||
当然，即使埃隆·马斯克成功地收购了推特，也没有人能够预测他会对推特做什么。说实话，他就像任何复杂算法一样不可预测。
|
||||
|
||||
那么，你是如何看待这个新闻的呢？你相信埃隆·马斯克说的话吗？欢迎在下面的评论中分享你的想法。

C 语言发展简史
|
||||
======
|
||||
|
||||
|
||||
|
||||
> 下面是我对 <ruby>布莱恩·克尼汉<rt>Brian Kernighan</rt></ruby> 的采访，他（与 <ruby>丹尼斯·里奇<rt>Dennis Ritchie</rt></ruby>）是《<ruby>C 程序设计语言<rt>The C Programming Language</rt></ruby>》一书的共同作者，我们谈及了 C 语言及其 50 年的历史。
|
||||
|
||||
![两位作者写的最初的 C 语言编程指南，大约是在 1978 年][1]
|
||||
|
||||
C 语言将在 2022 年满 50 岁。然而，尽管它历史悠久，在许多“流行编程语言”的调查中，C 语言仍然是“最常用”的编程语言之一。例如，你可以看看 [TIOBE 指数][2]，它追踪不同编程语言的流行程度。许多 Linux 应用程序是用 C 语言编写的，例如 GNOME 桌面。
|
||||
|
||||
我采访了 <ruby>[布莱恩·克尼汉][3]<rt>Brian Kernighan</rt></ruby>，以了解更多关于 C 语言及其历史他（与 <ruby>丹尼斯·里奇<rt>Dennis Ritchie</rt></ruby>）是《<ruby>C 程序设计语言<rt>The C Programming Language</rt></ruby>》一书的共同作者。
|
||||
|
||||
### C 语言是怎么诞生的呢？
|
||||
|
||||
C 语言由一系列旨在进行系统编程的语言演变而来，系统编程就是编写像编译器、汇编器、编辑器以及最终的操作系统这样的程序。麻省理工学院有一个与贝尔实验室合作的 Multics 项目，它计划用一种高级语言编写系统的所有部分（这在 1965 年那时候是一个新想法）。他们打算使用 IBM 的 PL/1，但它非常复杂，而且承诺的编译器也没有及时交付。
|
||||
|
||||
在与一个叫做 EPL 的子集（由贝尔实验室的<ruby>道格拉斯·麦克罗伊<rt>Douglas McIlroy</rt></ruby> 设计）进行了短暂交流后，Multics 转向了 BCPL，这是一个由剑桥的 Martin Richards 设计和实现的，更加简单和干净的语言，我记得他当时正在麻省理工学院访问。当 <ruby>肯·汤普逊<rt>Ken Thompson</rt></ruby> 开始研究后来的 Unix 时，他在 BCPL 的基础上创造了一种更简单的语言，他称之为 B 语言。在 1969 年，他为搭载了第一个 Unix 原型系统的 PDP-7 计算机实现了这种语言。
|
||||
|
||||
BCPL 和 B 都是“无类型”语言。也就是说，它们只有一种数据类型，即整数。DEC 公司的 PDP-11 计算机大约在 1971 年投入使用，它搭载了第一个真正的 Unix 系统。PDP-11 支持几种数据类型，特别是 8 位字节和 16 位整数。因此，一种同样支持几种数据类型的语言是更好的选择。这就是 C 语言的起源。
|
||||
|
||||
### C 语言在贝尔实验室和早期版本的 Unix 中是如何使用的呢？
|
||||
|
||||
C 语言最初只在 Unix 上使用，尽管过了一段时间，也有了用于其他机器和操作系统的 C 语言编译器。大多数情况下，它被用于系统级的编程，涵盖了相当多有趣的领域，还有很多用于管理 AT&T 电话网络运营的系统。
|
||||
|
||||
### 在贝尔实验室用 C 语言编写的最有趣的项目是什么？
|
||||
|
||||
可以说，最有趣、最令人难忘、也是最重要的 C 语言程序就是 Unix 操作系统本身。1971 年 Unix 的第一个版本是用 PDP-11 汇编语言编写的，但到了第四版，也就是 1973 年左右，我们用 C 语言重写了它。这很关键，因为这意味着操作系统（和它所有的支持软件）基本上可以通过重新编译来移植到不同类型的计算机上。虽然在实践中并没有那么简单，但也相差不远。
|
||||
|
||||
### 你与丹尼斯·里奇合著了《C 程序设计语言》一书。那本书是怎么来的，你和丹尼斯又是如何在书中合作的呢？
|
||||
|
||||
我曾经写过一本肯·汤普逊的 B 语言教程，帮助人们快速上手使用它。当 C 语言可用时，我将其升级为 C 语言的教程。过了一段时间，我说服了丹尼斯，让他和我一起写一本 C 语言的书。基本上，除了系统调用那章外，大部分的教程材料都是我写的，而丹尼斯已经写好了那个参考手册，写的非常棒。然后我们反复修改，使教程部分更加流畅。参考手册几乎保持不变，因为它从一开始就写得很好。这本书的格式是用 *troff* 格式器格式的，这是 Unix 上的许多工具之一，我做了大部分的格式化工作。
|
||||
|
||||
### C 语言什么时候成为了贝尔实验室以外的其他程序员用于工作的东西呢？
|
||||
|
||||
我真的记不大清了，但我认为大概是在最初的五六年里，C 语言主要是跟着 Unix 一起发展的。随着其他操作系统上的编译器的发展，它开始蔓延到 Unix 以外的其他系统。我不记得我们是什么时候意识到 C 和 Unix 产生了真正的影响，但应该是在 20 世纪 70 年代中后期。
|
||||
|
||||
### 为什么 C 语言会成为如此有影响力的编程语言呢？
|
||||
|
||||
早期的主要原因是它与 Unix 的联系，Unix 在世界上迅速传播。如果你使用 Unix，你就会用 C 语言来编程。后来，C 语言传播到不一定运行 Unix 的计算机上，很大程度上是因为 Steve Johnson 编写了可移植 C 语言编译器。在工作站领域，比如 <ruby>昇阳微系统<rt>Sun Microsystems</rt></ruby>、MIPS（后来成为 SGI）和其他公司，它们都是因为 Unix 和 C 语言的结合而获得成功。IBM PC 出现得稍晚一些，大约在 1982 年。后来 C 语言成为 MS-DOS 和 Windows 下的标准编程语言之一。今天，大多数物联网（IoT）设备会使用 C 语言。
|
||||
|
||||
### 在创建约 50 年后的今天，C 仍然是一种流行的编程语言。为什么它仍然如此受欢迎呢？
|
||||
|
||||
我认为 C 语言在效率和表现力这两个方面达到了一个平衡点。在早期，效率真的很重要，因为与我们今天所使用的计算机相比，当时的计算机速度很慢、内存十分有限。C 语言是非常高效的，因为它可以被编译成高效的机器代码，而且它也足够简单，人们很容易学会如何编译它。同时，它还具有很强的表现力，易于编写，并且结构紧凑。至少在我谦虚而正确的观点中，没有任何一种语言能很好地达到这种境界。
|
||||
|
||||
### 多年来，C 语言的发展和变化如何？
|
||||
|
||||
我想，C 语言的发展是适度的，但我并没有太注意 C 语言标准的发展。C 语言已经有足够的改变了，80 年代写的代码需要做一些前置工作才能编译，但这主要与诚实对待类型有关。比较新的功能，如复数，也许是有用的，但对我来说不是，所以我不能做出明智的评论。
|
||||
|
||||
### 哪些编程问题可以用C语言最容易解决？
|
||||
|
||||
嗯，对于任何事情来说，它都是一种很好的语言，但在今天，有了充足的内存和处理能力，大多数程序员都可以用 Python 这样的语言来进行内存管理和处理其他更高级的结构。C 语言仍然是底层编程的一个很好的选择，因为对于底层编程来说，充分利用 CPU 周期和每一个字节仍然很重要。
|
||||
|
||||
### C 语言影响了其他编程语言，包括 C++、Java、Go 和 Rust。你对这些编程语言有什么看法？
|
||||
|
||||
几乎每一种语言在某些方面都是对其前辈的反应。简单点说，C++ 增加了控制信息访问的机制，所以对于真正的大型程序来说，它比 C 更好。[Java][4] 是对 C++ 的复杂性的一种反应。Go 是对 C++ 的复杂性和 [Java][4] 的限制的一种反应。[Rust][5] 是对 C 语言（大概也是对 C++）中内存管理问题的一种尝试，同时它接近了 C 语言的效率。
|
||||
|
||||
它们都带来了某些积极的特性，但不知何故，没有人能够完全满意，所以总是会有更多的语言，反过来对以前的语言做出反应。同时，老的语言，在大多数情况下，仍会继续存在，因为它们的工作做得很好，而且有一个嵌入式的根据地，老的语言在里面可以完美使用，而用新的东西来重新实现是不可行的。

如何从 Ubuntu 20.04 LTS 升级到 Ubuntu 22.04 “Jammy Jellyfish”
|
||||
======
|
||||
|
||||
|
||||
s
|
||||
> 本文介绍从 Ubuntu 20.04 LTS 升级到 Ubuntu 之前，你所需要采取的完整步骤和预防措施。
|
||||
|
||||
[Ubuntu 22.04 LTS Jammy Jellyfish][1] 将在 2022 年 4 月 21 日发布。我建议你在该日期之后的一两个月后再升级。理想的情况下，如果你在第一次修正版本发布后，才计划升级到任意主要版本，这会是最好的选择。
|
||||
|
||||
但是，如果你迫切想要体验 Ubuntu 22.04 带来的令人震惊的更改和特色功能，那么，接下来请阅读用于完美升级过程的步骤。
|
||||
|
||||
### 在升级前
|
||||
|
||||
在任何升级前，遵循一些最佳的惯例总是更加明智的。这会防止出现一些升级后的问题，并引领通往成功的升级流程。
|
||||
|
||||
* 备份你的家目录中的数据到另一个驱动器或 USB 存储器，包括：图片、视频或其他的个人文件。
|
||||
* 如果你遇到一个不稳定的系统行，请保留一个准备好的 [Ubuntu 的现场 USB][2]。
|
||||
* 如果你打算升级 GNOME 工作站，请先禁用所有的 GNOME 扩展，因为这些扩展与 GNOME 3.36+ 不兼容。
|
||||
* 在成功的升级后，你可以逐一启用这些扩展。
|
||||
* 运行命令 `sudo apt update && sudo apt upgrade` 以确保你的系统是最新的软件包。
|
||||
* 关闭所有你正在运行的应用程序。
|
||||
* 重新启动你的系统。
|
||||
|
||||
说到这里，如果你准备好了，接下来遵循下面的说明来从 Ubuntu 20.04 LTS 升级到 Ubuntu 22.04 。
|
||||
|
||||
### 从 Ubuntu 20.04 和 Ubuntu 21.10 升级到 Ubuntu 22.04
|
||||
|
||||
#### 在 2022 年 4 月 21 日之前
|
||||
|
||||
如果你想在发布日期前升级，打开一个终端窗口，并运行下面的命令。
|
||||
|
||||
```
|
||||
sudo do-release-upgrade -d
|
||||
```
|
||||
|
||||
![Upgrade to Ubuntu 22.04 LTS from Ubuntu 20.04 LTS][3]
|
||||
|
||||
上面的命令将使用 “jammy” 来覆盖系统中的 “focal” 分支，以获取新的软件包。不仅如此，这个命令也会禁用你这些年可能添加的所有的第三方 PPA 。
|
||||
|
||||
此外，这个命令将花费一些时间才完成，这主要取决于你的网速。
|
||||
|
||||
除此之外，注意终端上偶尔出现的提示，它需要你输入 `Y` 或 `N` 。另外，如果你中途取消升级过程，这些第三方 PPA 也不会被启用，你必须手动启用它们。
|
||||
|
||||
![Summary of the upgrade][4]
|
||||
|
||||
最后，这个命令将计算升级系统所需软件包的大小，并估算所需时间，摘要如下图所示。请仔细地阅读它，并允许升级到 Ubuntu 22.04 LTS Jammy Jellyfish。
|
||||
|
||||
在升级过程完成后，重新启动你的系统，享受令人兴奋的 Ubuntu 22.04 LTS 。
|
||||
|
||||
#### 在 2022 年 4 月 21 日之后
|
||||
|
||||
在 2022 年 4 月 21 日当天或之后，直到 2022 年 07 月第一次修正版本发布，Ubuntu 都不会给予你任何可视化的升级提示，因为第一个修改版本被认为是初始错误被消除后最稳定的版本。
|
||||
|
||||
这意味着，你要么等到 7 月，你要么强制升级。如何强制升级？打开“<ruby>软件和更新<rt>Software and Updates</rt></ruby>”，转到“<ruby>更新<rt>Updates</rt></ruby>”标签页。更改“<ruby>通知我有新的 Ubuntu 版本<rt>Settings notify me of new ubuntu version</rt></ruby>” 为 “<ruby>任意新的 Ubuntu 版本<rt>any new version</rt></ruby>”。
|
||||
|
||||
在完成后，你应该会在桌面上看到一个升级提示。遵循屏幕上的指示，接着继续升级过程。
|
||||
|
||||
这个提示也会计算升级系统所列软件包所需的时间，因此，仔细的阅读更新程序的输出内容。在你准备好了以后，开始升级过程。
|
||||
|
||||
最后，在升级过程完成后，重新启动系统，享受全新的 Ubuntu 22.04 LTS Jammy Jellyfish 。
|
||||
|
||||
#### 从 Ubuntu 21.10 升级到 Ubuntu 22.04
|
||||
|
||||
针对 Ubuntu 21.10 ，你也可以参考上面确切说明来升级。从 Ubuntu 21.10 升级到 Ubuntu 22.04 不需要额外的步骤。
|
||||
|
||||
#### 升级到 Ubuntu 22.04 的过程需要多长的时间?
|
||||
|
||||
根据我的测试，在默认安装的情况下，整个升级过程需要 30 多分钟。根据你安装的软件包的数量和安装的年限，你的系统可能会更多。因此，相应地计划你的时间。
|
||||
|
||||
### 总结
|
||||
|
||||
最后，我希望这些步骤能帮助你成功地升级你的 Ubuntu 系统到 Jammy Jellyfish 。如果你正在打算升级，祝你一切顺利。
|
||||
|
||||
请在下面的评论区中告诉我升级过程是如何进行的。

禁用 Cinnamon 桌面的动画以略微加速你的 Linux Mint 系统
|
||||
======
|
||||
|
||||
|
||||
|
||||
让我们面对现实吧。
|
||||
|
||||
与 GNOME 等相比，Cinnamon 已经是一个轻量的桌面环境了。虽然它占用的资源可能没有 Xfce 那么低。
|
||||
|
||||
不过，如果你有一个硬件不足的系统，并且你想要提升一点性能，而不想切换到 Xfce 等替代性<ruby>桌面环境<rt>Desktop Environment</rt></ruby>（DE）或 [Sway][1]、[Fluxbox][2] 等<ruby>窗口管理器<rt>Window Manager</rt></ruby>（WM）的话，我这里倒是有一个实用小技巧可以分享给你。它应该帮助你加快 Linux Mint 的速度，虽然只能够加快一点点。
|
||||
|
||||
### 禁用 Cinnamon 桌面的动画效果
|
||||
|
||||
**首先，你一定不要指望用这个小技巧来大幅提高整体桌面性能。原因如下：**
|
||||
|
||||
当你打开/关闭应用程序窗口、使用菜单、弹出对话框等时，你会注意到这些<ruby>动画<rt>animations</rt></ruby>或<ruby>效果<rt>effects</rt></ruby>。由于这些事件都是短暂的，不会持续运行，因此禁用它们并不能得到很大提升。
|
||||
|
||||
如果你的系统真的在崩溃的边缘挣扎，禁用这些效果可能有助于减少卡顿。真的到了这种时候，能快一点是一点。让我们来看看该怎么做吧！
|
||||
|
||||
首先，打开菜单，搜索“<ruby>效果<rt>effects</rt></ruby>”。
|
||||
|
||||
![打开 Linux Mint Cinnamon 的效果设置][3]
|
||||
|
||||
打开“<ruby>效果<rt>effects</rt></ruby>”设置窗口，你默认会在“<ruby>启用效果<rt>Enable Effects</rt></ruby>”这个标签页中。你可以在这里选择禁用（或启用）各种可用的动画效果。
|
||||
|
||||
![禁用 Linux Mint Cinnamon 桌面的动画][4]
|
||||
|
||||
你可以选择禁用部分或全部效果。
|
||||
|
||||
如果你切换到“<ruby>自定义<rt>Customize</rt></ruby>”标签页，你可以自定义你在“<ruby>启用效果<rt>Enable Effects</rt></ruby>”标签页中看到的各种效果。
|
||||
|
||||
![自定义 Linux Mint Cinnamon 中的窗口动画][5]
|
||||
|
||||
第一栏是效果的名称，第二栏是动画的类型，第三栏是动画的展示方式，在最后一栏，你可以配置动画完成的时间。
|
||||
|
||||
如果你选择了 “None”、“easeNone” 和 “0” 时长，就相当于禁用了这个效果。不过，使用另一个标签中的禁用选项是一个更简单的选择。
|
||||
|
||||
### 值得这样做吗？
|
||||
|
||||
我写这个小技巧的原因是，有读者问我能否定制 Cinnamon 并禁用动画。
|
||||
|
||||
说实话，这并不费什么劲，而且做了之后也没有多大区别。你几乎不会注意到视觉上的影响，更别说是性能上的改进了。
|
||||
|
||||
但是，如果你的系统正处于挣扎状态，每一个微小的优化都会有帮助。你也可以尝试使用消耗较少系统资源的轻量级应用程序。这或许对你也有一点帮助。
|
||||
|
||||
你有任何类似的优化小技巧吗？请在评论区和大家分享吧！

我如何在 Linux 上扫描家庭照片
|
||||
======
|
||||
|
||||
> 有了 Linux，我可以用意想不到的方式与我的先辈们联系。
|
||||
|
||||
|
||||
|
||||
Linux 不仅仅是在服务器上运行、为互联网提供动力的东西。它是你的数据、你的家庭历史和记忆、工作或娱乐以及现实生活的安全场所。
|
||||
|
||||
这就是例子：现在我正在进行一个扫描家庭老照片的项目。我使用带有 GNOME 桌面的 Fedora Linux 已经有几年了，所以我不需要安装任何额外的软件包。我只是把扫描仪插入 USB 接口，启动扫描软件（<ruby>文档扫描器<rt>Document Scanner</rt></ruby>），就可以了。请继续阅读，看看我是如何做到的。
|
||||
|
||||
### 将记忆数字化
|
||||
|
||||
许多人对了解他们的家族历史、先辈们和遗产感兴趣。随着现在技术的发展，将旧的人工制品数字化已经成为一种普遍的做法。无论是你的 80 年代的磁带收藏，还是高中的艺术作品，或者是家庭的老照片，把它们变成数字格式是一种现代的保存和未来验证的方法。
|
||||
|
||||
我的妈妈最近给了我一些先辈们的照片，所以我有几张想保存的图片。扫描它们不仅提供了某种意义上的永久性，而且使我能够以在拍摄它们的时代闻所未闻的方式来处理它们。例如，我有一张我祖父的照片，他在我出生前几年不幸去世。通过将他的照片数字化，我可以放大，了解他，并可能以一种原本不可能的方式与他建立联系。
|
||||
|
||||
### 工作流程
|
||||
|
||||
首先要做的是把我的佳能扫描仪插入 USB 接口。当我打开文档扫描器时，它检测到我的 Canon LiDE 210 扫描仪。接下来，我把照片放到平板扫描仪上。我将设置调整为 2400 DPI 的图像分辨率，以确保我捕捉到每一个细节。
|
||||
|
||||
然后我点击扫描。在这种分辨率下，扫描可能需要一些时间，但完成后，我可以根据需要裁剪图像并保存它。
|
||||
|
||||
顺便说一下，在我扫描照片和写这篇文章的时候，我也在用一个开源的音频播放器 [Clementine][2] 在同一台电脑上欣赏我最喜欢的一些音乐。性能受到影响？一点也不。
|
||||
|
||||
扫描完成后，我还可以选择裁剪图片并将其保存为 PDF、JPG 或任何我选择的格式。
|
||||
|
||||
### 现实生活
|
||||

### 总结
|
||||
|
||||
作为一个专门的 Linux 桌面用户，我有时会听到有人说他们不使用 Linux，因为有一些任务它不能执行。Linux 是我使用的全部，而且在大约 14 年的时间里，我没有遇到这个问题。无论你是在寻找一种愉快的消遣，还是寻找一种提高工作效率的方法，都有可能有一种在 Linux 上运行的解决方案适合你。

使用 Podman 运行一个 “hello world” MLCube
|
||||
======
|
||||
|
||||
|
||||
|
||||
[MLCube][2] 是一个新的基于基础设施规范的开源容器，被引入到基于 Python 的机器学习工作流程中，以实现可重复性。它可以利用诸如 [Podman][3]、[Singularity][4] 和 [Docker][5] 等工具。也支持在远程平台上的执行。开发 MLCube 的 MLCommons 最佳实践工作组的主席之一是来自 Red Hat 的 [Diane Feddema][6]。这篇介绍性文章解释了如何在 Fedora Linux 上使用 Podman 运行 [“hello world” MLCube 例子][7]。
|
||||
|
||||
[Yazan Monshed][8] 写了一篇关于 [Fedora 上的 Podman][9] 的非常有用的介绍，对这里使用的一些步骤给出了更多细节。
|
||||
|
||||
首先安装必要的依赖项。
|
||||
|
||||
```
|
||||
sudo dnf -y update
|
||||
sudo dnf -y install podman git virtualenv \
|
||||
policycoreutils-python-utils
|
||||
```
|
||||
|
||||
然后，按照文档的要求，设置一个虚拟环境并获得示例代码。为了确保可重复性，使用一个特定的提交，因为该项目正在积极改进。
|
||||
|
||||
```
|
||||
virtualenv -p python3 ./env_mlcube
|
||||
source ./env_mlcube/bin/activate
|
||||
git clone https://github.com/mlcommons/mlcube_examples.git
|
||||
cd ./mlcube_examples/hello_world
|
||||
git checkout 5fe69bd
|
||||
pip install mlcube mlcube-docker
|
||||
mlcube describe
|
||||
```
|
||||
|
||||
现在，通过编辑 $HOME/mlcube.yaml 文件，将运行器命令从 `docker` 改为 `podman`，即：
|
||||
|
||||
```
|
||||
docker: docker
|
||||
```
|
||||
|
||||
改为：
|
||||
|
||||
```
|
||||
docker: podman
|
||||
```
|
||||
|
||||
如果你使用的是 x86_64 架构的电脑，你可以用以下方式获取容器：
|
||||
|
||||
```
|
||||
mlcube configure --mlcube=. --platform=docker
|
||||
```
|
||||
|
||||
你会看到一些选项：
|
||||
|
||||
```
|
||||
? Please select an image:
|
||||
▸ registry.fedoraproject.org/mlcommons/hello_world:0.0.1
|
||||
registry.access.redhat.com/mlcommons/hello_world:0.0.1
|
||||
docker.io/mlcommons/hello_world:0.0.1
|
||||
quay.io/mlcommons/hello_world:0.0.1
|
||||
```
|
||||
|
||||
选择 `docker.io/mlcommons/hello_world:0.0.1` 来获取容器。
|
||||
|
||||
如果你的电脑不是 x86_64 架构的，你需要构建容器。改变文件 `$HOME/mlcube.yaml`，将这一行：
|
||||
|
||||
```
|
||||
build_strategy: pull
|
||||
```
|
||||
|
||||
变为：
|
||||
|
||||
```
|
||||
build_strategy: auto
|
||||
```
|
||||
|
||||
然后用以下方法构建容器：
|
||||
|
||||
```
|
||||
mlcube configure --mlcube=. --platform=docker
|
||||
```
|
||||
|
||||
要运行测试，你可能需要在目录中适当地设置 SELinux 权限。你可以通过输入以下内容来检查 SELinux 是否已经启用：
|
||||
|
||||
```
|
||||
sudo sestatus
|
||||
```
|
||||
|
||||
应该会有类似这样的输出：
|
||||
|
||||
```
|
||||
SELinux status: enabled
|
||||
...
|
||||
```
|
||||
|
||||
[Josphat Mutai][10]、[Christopher Smart][11] 和 [Daniel Walsh][12] 解释说，在为容器使用的文件设置适当的 SELinux 策略时，你需要谨慎。在这里，你将允许容器读取和写入 `workspace` 目录。
|
||||
|
||||
```
|
||||
sudo semanage fcontext -a -t container_file_t "$PWD/workspace(/.*)?"
|
||||
sudo restorecon -Rv $PWD/workspace
|
||||
```
|
||||
|
||||
现在检查目录策略：
|
||||
|
||||
```
|
||||
ls -Z
|
||||
```
|
||||
|
||||
输出结果类似于：
|
||||
|
||||
```
|
||||
unconfined_u:object_r:user_home_t:s0 Dockerfile
|
||||
unconfined_u:object_r:user_home_t:s0 README.md
|
||||
unconfined_u:object_r:user_home_t:s0 mlcube.yaml
|
||||
unconfined_u:object_r:user_home_t:s0 requirements.txt
|
||||
unconfined_u:object_r:container_file_t:s0 workspace
|
||||
```
|
||||
|
||||
现在运行这个例子：
|
||||
|
||||
```
|
||||
mlcube run --mlcube=. --task=hello --platform=docker
|
||||
mlcube run --mlcube=. --task=bye --platform=docker
|
||||
```
|
||||
|
||||
最后，检查输出：
|
||||
|
||||
```
|
||||
cat workspace/chats/chat_with_alice.txt
|
||||
```
|
||||
|
||||
有类似于以下的文字：
|
||||
|
||||
```
|
||||
Hi, Alice! Nice to meet you.
|
||||
Bye, Alice! It was great talking to you.
|
||||
```
|
||||
|
||||
你可以按照 [这里][13] 的描述创建你自己的 MLCube。欢迎对 [MLCube 示例库][14] 做出贡献。[Udica][15] 是一个新项目，它承诺为容器提供更精细的 SELinux 策略控制，便于系统管理员应用。这些项目的积极开发正在进行中。对它们进行测试并提供反馈，将有助于使带有 SELinux 的系统上的安全数据管理更容易、更有效。

AlmaLinux 9.0 测试版来了，与 RHEL 9 同步
|
||||
======
|
||||
|
||||
> AlmaLinux 9 Beta 发布了，跟上了最新的 RHEL 9，还有一些软件包的更新和变化。
|
||||
|
||||
|
||||
|
||||
AlmaLinux 是一个流行的企业级 Linux 发行版，它刚刚宣布了 9.0 测试版，以和上游系统（RHEL 9）保持同步。
|
||||
|
||||
让我先来提供一些背景介绍吧。AlmaLinux 在 2021 年初推出，以取代当时刚停产的 CentOS。它的主要目标之一是成为 RHEL 的替代品，特别是需要达到 100% 的二进制兼容。
|
||||
|
||||
不要忘了，AlmaLinux 是免费的，这使得它成为 [最好的 RHEL 替代品之一][1]。
|
||||
|
||||
作为一个注重稳定性的发行版，它并没有很多新的功能。不过，它确实有很多软件包的更新，本文将介绍逐一它们。
|
||||
|
||||
让我们来看一看吧！
|
||||
|
||||
### 有什么新功能？
|
||||
|
||||
作为 RHEL 的克隆版，它几乎继承了 RHEL 9.0 测试版的所有功能。
|
||||
|
||||
* [Linux 5.14 内核][2]
|
||||
* SELinux 性能改进
|
||||
* 更新的软件包
|
||||
|
||||
#### Linux 5.14 内核
|
||||
|
||||
这绝对是最大的升级，Linux 5.14 内核带来了更新的硬件支持和其他各种改进。虽然与 AlmaLinux 的目标用户不是特别相关，但它确实包括了我很欣赏的 Radeon 卡的热拔插功能。
|
||||
|
||||
除此之外，这是一个相当小的版本，它最大的卖点可能是 [紧跟在 Linux 30 周年之后发布][2]。
|
||||
|
||||
#### SELinux 性能改进
|
||||
|
||||
![][3]
|
||||
|
||||
和所有的安全措施一样，SELinux 总是会对性能产生轻微的影响。虽然这在很大程度上是最小的，但它总是还有改进空间，而这个版本貌似就有性能改进。
|
||||
|
||||
正如红帽 [博文][4] 中所展示的那样，其中一些性能改进是相当显著的。从上图可以看出，在显示的指标中，Linux 5.14 内核（蓝色）的 SELinux 性能明显好于 Linux 5.6 内核（红色）。
|
||||
|
||||
总的来说，性能有所提升，包括开销（从大约 30 MB 提升至大约 15 MB）和文件创建时间（从大约 55 ms 提升至大约 44 ms）。
|
||||
|
||||
#### 更新的软件包
|
||||
|
||||
这个版本包含了大量的软件包更新。其中一些比较重要的包括 Git 2.31、PHP 8.0、Perl 5.32 和 MySQL 8.0。GCC 也更新到了 11.2 版本。
|
||||
|
||||
有了这些更新，它应该是对更多现代标准有更好的兼容性。
|
||||
|
||||
与上游相比，它也有一些软件包被删除。关于完整的变化列表，请参考 [官方发布说明][5]。
|
||||
|
||||
### 总结
|
||||
|
||||
总的来说，我认为 AlmaLinux 9.0 正在成为一个相当不错的版本，特别是当我看到了这个测试版中的改进。
|
||||
|
||||
AlmaLinux 9.0 测试版可用于 x86_64、arch64、ppc64le 和s390x 等架构。如果你想试用 AlmaLinux 9.0 测试版，请点击下方链接前往它的官网。
|
||||
|
||||
> [AlmaLinux 9.0 测试版][6]
|
||||
|
||||
请注意，它还没有准备好用于生产服务器，目前仅限于测试使用。
|
||||
|
||||
你打算从 CentOS 转到 AlmaLinux 吗？请在下面的评论中告诉我们吧！

Ubuntu Studio 22.04 LTS - 新功能和发布细节
|
||||
======
|
||||
|
||||
|
||||
|
||||
> Ubuntu Studio 22.04 LTS “Jammy Jellyfish” 的新特性和增强功能列表。
|
||||
|
||||
[Ubuntu Studio][1] 是 Ubuntu 的官方特色版，专门为那些主要从事图形、音频和视频工作的创作者服务。这个官方发行版在其 ISO 镜像中预装了几乎所有流行的开源创意软件，为你提供了一个现成而稳定的系统来启动你的专业工作。
|
||||
|
||||
![Ubuntu Studio 22.04 LTS Desktop][2]
|
||||
|
||||
### Ubuntu Studio 22.04 LTS - 新功能
|
||||
|
||||
像所有的 Ubuntu 官方版本一样，Ubuntu Studio 22.04 LTS 基于 [Ubuntu 22.04 LTS “Jammy Jellyfish”][3]。Linux 内核 5.15 LTS 为 Ubuntu Studio 22.04 提供支持，这是一个稳定的内核，适合目前所有的现代硬件阵容。
|
||||
|
||||
大多数创造性的工作通常发生在高端和现代的机器上；因此内核版本在 Ubuntu Studio 中是很重要的。[Linux 内核 5.15 LTS][4] 支持英特尔和 AMD 当前的 CPU/GPU 阵容。例如，这个内核带来了用于高带宽 I/O 操作的 AMD PTDMA 驱动和许多基本的更新，这对现代硬件的创造性工作非常重要。
|
||||
|
||||
除此之外，定制的 [KDE Plasma 5.24][5] 和 KDE Framework 5.92 带来了友好的用户界面和 Ubuntu Studio 的原生深色主题和图标主题。KDE Plasma 桌面被调整为带有快捷方式和必要的系统托盘部件的顶部面板，使所有的专业工作更加流畅。
|
||||
|
||||
此外，如果你从 Ubuntu Studio 20.04 LTS Focal Fossa 迁移到这个版本，KDE Plasma 是用户将体验到的一个新桌面。因为 Ubuntu Studio 20.04 LTS 是最后一个带有 Xfce 桌面环境的版本。而从那时起，Ubuntu Studio 已经转向了 KDE Plasma 桌面环境，以获得更好的现代技术和性能支持。
|
||||
|
||||
#### 应用栈
|
||||
|
||||
Ubuntu Studio 22.04 LTS 的应用栈带来了最新的稳定版本。Studio Controls（Ubuntu Studio 的本地控制中心）升级到了 2.3.0 版本，改进了混音器和插件，并修复了错误。
|
||||
|
||||
![Studio Controls][6]
|
||||
|
||||
除此之外，图形、视频和音频软件套件也都更新了它们的最新稳定版本。此外，如果你和上一个 LTS 版本做一个功能对比，你可能会注意到功能和改进的大规模升级。主要是针对 Blender、KDenlive 和 Ardour，因为这些超级令人印象深刻的开源应用在开发中非常活跃。
|
||||
|
||||
不过，我们在这里列出的主要应用并不是完整清单：
|
||||
|
||||
* Blender v3.0.1 （3D 计算机图形）
|
||||
* KDenlive v21.12.3 （视频编辑）
|
||||
* Krita v5.0.2 （光栅图形绘制和动画）
|
||||
* Gimp v2.10.24 （光栅图形绘制）
|
||||
* Ardour v6.9 （[数字音频工作站][8]）
|
||||
* Scribus v1.5.7 （桌面出版）
|
||||
* Darktable v3.6.0 （RAW 图像和照片管理）
|
||||
* Inkscape v1.1.2 （矢量图形编辑器）
|
||||
* Carla v2.4.2 （音频插件主机）
|
||||
* Studio Controls v2.3.0 （音频管理和控制）
|
||||
* OBS Studio v27.2.3 （流媒体应用）
|
||||
* MyPaint v2.0.1 （简单绘画）
|
||||
|
||||
此外，Jammy Jellyfish 的重大变化之一是引入了 [Pipewire][9] 0.3.48（与 Focal Fossa 相比）。这种现代音频和视频流服务器技术将帮助许多用户进行高级音频控制。但它可能需要命令行的调整来管理它。我不确定 Studio 团队未来是否会在 Studio 控制工具中带来额外的设置来管理 Pipewire。
|
||||
|
||||
最后，Ubuntu Studio 团队新设计的标志与 Canonical 的品牌形象相一致，看起来令人印象深刻，在这个版本中非常突出。
|
||||
|
||||
![Ubuntu Studio New Logo][10]
|
||||
|
||||
### 下载和升级
|
||||
|
||||
上述所有的应用使得 Ubuntu Studio 22.04 LTS 的 ISO 大小达到了惊人的 4GB 以上（它不能装在一张 DVD 里 ，要用 USB）。如果你想试试，你可以使用下面的链接下载 BETA 镜像。
|
||||
|
||||
> **[ubuntustudio-22.04-beta-dvd-amd64.iso][11]**
|
||||
|
||||
> **[ubuntustudio-22.04-beta-dvd-amd64.iso.torrent][12]**
|
||||
|
||||
如果你打算从 Ubuntu Studio 20.04 LTS 升级到这个新版本，需要注意一下。由于桌面环境从 Xfce 变为 KDE Plasma，你不应该从 Ubuntu Studio 20.04 LTS 升级到 Ubuntu 22.04 LTS。这种方式不支持。
|
||||
|
||||
相反，你应该进行全新的安装。重新安装可能会有点复杂和挑战，因为你已经在系统中设置了许多插件、设置和建立了音频和视频工作的工作流程。但我还是建议你这样做，因为这样可以让你在 Ubuntu Studio 22.04 LTS 中清理一下，然后用一套新的应用和桌面环境重新开始。

Ubuntu 22.04 LTS 发布！
|
||||
======
|
||||
|
||||
> Ubuntu 22.04 LTS 带来了许多惊喜，还带来了 GNOME 42，以及 Canonical 的新品牌/标志。
|
||||
|
||||
|
||||
|
||||
迫不及待地想尝试 Ubuntu 22.04 LTS？那么，它终于可以下载和升级了。（LCTT 译注：升级还要等几天，还存在一些小问题）
|
||||
|
||||
它带来了 [大量令人印象深刻的功能][1]，其中 GNOME 42 和树莓派桌面支持是其主要亮点。
|
||||
|
||||
现在，它已经就绪。在你决定尝试之前，让我们花点时间来看看这个版本最重要的变化。
|
||||
|
||||
### Ubuntu 22.04 LTS 的新变化
|
||||
|
||||
Ubuntu 22.04 是一次主要版本升级，其包括了桌面环境的改进、视觉上的变化和一些新增的功能。
|
||||
|
||||
如果你正在使用 Ubuntu 20.04 LTS，想知道它们之间的区别，你可以查看我们的《[Ubuntu 20.04 vs Ubuntu 22.04 LTS][2]》文章来了解。
|
||||
|
||||
毫无疑问，这是一个 <ruby>[长期支持][3]<rt>Long-Term Support</rt></ruby> （LTS）版本。所以，你可以期待它维护更新到 2027 年，也就是五年的支持。一些最显著的变化包括：
|
||||
|
||||
#### 1、强调色的选择
|
||||
|
||||
虽然大多数基于 Ubuntu 的 Linux 发行版提供了设置强调色的功能，但你必须使用 <ruby>[GNOME 优化][4]<rt>GNOME Tweaks</rt></ruby> 才能做到。
|
||||
|
||||
![][5]
|
||||
|
||||
现在，在 Ubuntu 22.04 中，你可以轻松地设置你所选择的强调色，它会影响到文件夹、通知区和桌面体验的其他元素。
|
||||
|
||||
#### 2、GNOME 42
|
||||
|
||||
![][6]
|
||||
|
||||
期待已久的桌面环境升级来了。虽然 Ubuntu 22.04 的 GNOME 实现并不提供水平停靠区，但会有其它好处加成。
|
||||
|
||||
你应该能够在 Ubuntu 22.04 LTS 中体验到所有 [GNOME 42 的优点][7]。不幸的是，你仍然会发现几个版本号是 41 的应用程序。
|
||||
|
||||
开发者提到，他们需要更多的时间来测试使用 [libadwaita][8] 的应用程序。
|
||||
|
||||
话虽如此，在你继续阅读时，我也会提到 GNOME 42 所带来的有趣的更多功能。
|
||||
|
||||
#### 3、新的屏幕截图工具
|
||||
|
||||
![][9]
|
||||
|
||||
与 Ubuntu 20.04 LTS 不同，你不能用 `PrtScrn`（或任何其他指定的快捷键）来直接抓拍全屏图片。
|
||||
|
||||
相反，如果你按下快捷键来截图，就会弹出来这个新的截图工具。
|
||||
|
||||
这不仅体验更加直观，而且还支持屏幕录制。因此，这是一个相当令人激动的变化！
|
||||
|
||||
#### 4、深色模式的改进
|
||||
|
||||
虽然我们已经有了深色模式，但它并不是一个完美的系统级实现。
|
||||
|
||||
感谢 [elementary OS 6][10]，GNOME 42 受到启发，实现了系统级的深色模式，更好地融合在一起以保持一致性。
|
||||
|
||||
![][11]
|
||||
|
||||
#### 5、Firefox 变成了 Snap 版本
|
||||
|
||||
![][12]
|
||||
|
||||
从 deb 包到 Snap 的过渡已经进行了一段时间了。
|
||||
|
||||
在 Ubuntu 22.04 中，Firefox 现在将默认以 Snap 包出现，在 Mozilla 的共同努力下，旨在推动更快的安全更新，并确保无需维护许多东西即可实现跨发行版的支持。
|
||||
|
||||
沙盒化的 Firefox 体验也应该可以提供更好的安全性。
|
||||
|
||||
你可以在这个 [论坛帖子][13] 中阅读更多关于该决定背后的信息。
|
||||
|
||||
#### 6、桌面图标出现在底部
|
||||
|
||||
![][14]
|
||||
|
||||
默认情况下，桌面图标可以在右上角的区域看到，靠近停靠区。
|
||||
|
||||
现在，在 Ubuntu 22.04 中，默认的桌面图标位置已经被改为底部。你可以通过“<ruby>外观<rt>Appearance</rt></ruby>”设置中的选项来改变这一点。
|
||||
|
||||
#### 7、缩小停靠区的能力
|
||||
|
||||
如果你不喜欢停靠区占据了整个左侧区域，你可以改变它。
|
||||
|
||||
你需要禁用“<ruby>外观<rt>Appearance</rt></ruby>”调整中停靠区设置下的“<ruby>面板<rt>Panel</rt></ruby>”模式，如下图所示：
|
||||
|
||||
![][15]
|
||||
|
||||
这将分离出停靠区，并提供现代桌面体验的浮动效果。
|
||||
|
||||
#### 8、树莓派桌面支持
|
||||
|
||||
Ubuntu 22.04 是第一个也可用于树莓派的桌面 LTS 版本。
|
||||
|
||||
随着 [zswap 的引入][16]，树莓派的性能应该会在 Ubuntu 22.04 中得到显著提升。
|
||||
|
||||
它甚至可以 [在 2GB 的树莓派 4 变体型号上运行][16]。你可以在你的树莓派上测试这些改进。
|
||||
|
||||
#### 9、使用 Ubuntu Advantage
|
||||
|
||||
![][17]
|
||||
|
||||
Ubuntu Advantage 是为企业和商家提供的高级订阅，无需重新启动即可获得重要的安全更新。
|
||||
|
||||
对于大多数桌面用户来说，这不是什么有用的东西。然而，如果你想获得 Ubuntu Advantage 订阅，并将你的系统接驳到它，你可以通过导航到“<ruby>软件 & 更新<rt>Software & Updates</rt></ruby>”下的 Livepatch 部分轻松做到这一点。
|
||||
|
||||
#### 10、Linux 内核 5.17 和 Linux 内核 5.15 LTS
|
||||
|
||||
[Linux 内核 5.15 LTS][18] 是一个重要的升级，它改进了 NTFS 驱动，对即将到来的英特尔独立显卡提供了初步支持，并有更多的性能改进。
|
||||
|
||||
对于你的桌面计算机，你应该注意到 Linux 内核 5.15 开箱即用。
|
||||
|
||||
Ubuntu 服务器版也采用了 Linux 内核 5.15 LTS。
|
||||
|
||||
然而，Ubuntu 22.04 也在最新一代认证设备（OEM）上使用了 [Linux 内核 5.17][19]。
|
||||
|
||||
因此，在这个版本中，Ubuntu 根据产品的不同打包了多个内核。
|
||||
|
||||
#### 11、RISC-V 的现场镜像
|
||||
|
||||
从 Ubuntu 22.04 开始，你会发现单独的可用 RISC-V 架构的<ruby>现场镜像<rt>live image</rt></ruby>。
|
||||
|
||||
#### 其他变化
|
||||
|
||||
除了上面提到的主要变化外，升级后的其他一些重大变化包括。
|
||||
|
||||
* 较新的软件包，如 OpenSSL 3.0、Ruby 3.0、Python 3.10、PHP 8.1 等。
|
||||
* 更新的应用程序，包括 Firefox 99、LibreOffice 7.3 和Thunderbird 91。
|
||||
|
||||
你可以看一下它的 [官方发布说明][20] 来探索所有的技术变化。
|
||||
|
||||

Ubuntu Unity 22.04 LTS 新功能体验
|
||||
======
|
||||
|
||||
> Ubuntu Unity 22.04 LTS 中的新功能和软件包，带来了精心策划的 Unity 桌面。
|
||||
|
||||
Ubuntu Unity 是 Ubuntu 的一个非官方版本，提供了 Unity 桌面环境。Unity 桌面环境是由 Canonical 在十年前创建的，而后在 Ubuntu 18.04 “Bionic Beaver” 发布后被 [放弃了][1]，Ubuntu 转而使用了 GNOME 桌面。随着 Ubuntu 22.04 LTS 的发布，Ubuntu Unity 的小团队发布了 Ubuntu Unity 22.04 LTS Linux 发行版。
|
||||
|
||||
![Nice and Clean Ubuntu Unity 22.04 LTS][2]
|
||||
|
||||
### Ubuntu Unity 22.04 LTS - 新功能
|
||||
|
||||
抛开历史不谈，Ubuntu Unity 22.04 LTS 带来了 Unity7 桌面环境，并与 Jammy Jellyfish 版本保持了一致的变化。该版本的核心是基于 [Ubuntu][3] 的底层软件包和 [Linux 内核 5.15][4] 。Linux 内核 5.15 支持所有主流的 GPU、CPU 和其他硬件阵容，让你可以在你的硬件上自由使用这个发行版。
|
||||
|
||||
此外，在此版本中自然有 Unity 桌面的主要魅力所在，即搜索应用的全局 HUD 和所有应用都有的全局菜单。也许，很多人喜欢 Unity 就是因为它的全局 HUD（通过 `META` 键启动），这是一个搜索、启动或做任何事情的单一入口点。
|
||||
|
||||
![Global HUD in Ubuntu Unity 22.04][5]
|
||||
|
||||
它基本上就像是 KDE Plasma 中的 [KRunner][6]。另外，它的全局菜单使应用看起来更漂亮，并节省了宝贵的屏幕空间。而且，该团队还为 Unity 桌面带来了定制的 Yaru 主题，有浅深两款。
|
||||
|
||||
![Global Menu in Ubuntu 22.04 with LibreOffice Calc][7]
|
||||
|
||||
除此之外，应用列表也有些不同，与基本的 Ubuntu GNOME 版本相比，它提供了各种基本用途的应用。比如，它用 Nemo 文件管理器代替了 GNOME 中的 “文件”，以及来自 MATE 桌面软件包的 Pluma 文本编辑器。
|
||||
|
||||
不包括 Nautilus/“文件” 是明智的，因为要做全部的 GTK4 和 libadwaita 移植工作。对于 Unity 桌面来说，这需要太多的工作，而其他的解决方案也可以有效地工作。
|
||||
|
||||
此外，在 Ubuntu Unity 22.04 LTS 中使用了 GNOME “软件” 41.5，安装和删除软件变得很容易。虽然它是一个 GNOME 41+ 系列的应用，但在 Unity 桌面外观下，它看起来很优雅。但它没有全局菜单，因为它的软件设计原则本身就没有传统的文件菜单栏。
|
||||
|
||||
#### 外观和感觉
|
||||
|
||||
但这还不是全部。Unity 桌面为你提供了大量的自定义选项，通过外观设置来选择基础主题、启动器图标大小和位置，以及其他 Unity 桌面的基本设置。如需进一步配置，你可以得到预装的 Unity Tweak 工具，它为你提供了更多额外的选项，使你的桌面成为你想要的样子。
|
||||
|
||||
最后，在这个版本中，以官方吉祥物 Jammy Jellyfish 为特色的一组迷人的墙纸为整个 Unity 桌面体验增色不少。
|
||||
|
||||
![Unity Tweak Tool][9]
|
||||
|
||||
### 总结和下载
|
||||
|
||||
作为总结，下面是 Ubuntu Unity 22.04 版本中的应用组合：
|
||||
|
||||
* 基于 Ubuntu 22.04 LTS “Jammy Jellyfish”
|
||||

Pop OS 22.04 LTS – New Features and Release Updates
|
||||
======
|
||||
System76 released the Pop OS 22.04 LTS Beta copy on GitHub. We unwrap
|
||||
the new features and updates in this post.
|
||||
System76 released the Pop OS 22.04 LTS Beta copy on GitHub. We unwrap the new features and updates in this post.
|
||||
|
||||
System76’s POP OS is based on Ubuntu releases, and the [Ubuntu 22.04 LTS release][1] is around the corner. Following the release schedule, the beta ISO of Pop OS 22.04 is now available for download and test on GitHub. The BETA ISO is not stable yet, but you can download and do some hands-on to find out the new features.
|
||||
|
||||
### POP OS 22.04 LTS – New Features
|
||||
|
||||
![Pop OS 22.04 Desktop \(beta\)][2]
|
||||
|
||||
The major highlight of Ubuntu 22.04 LTS is the customized version of GNOME 42. Because the vanilla GNOME 42 brings the libadwaita/GT4 conversion of entire GNOME Core and native applications. But Ubuntu 22.04 LTS plans to include some of them with its unique flavours, such as Accent Color.
|
||||
|
||||
Obviously, you might be wondering how GNOME 42 looks inside Pop OS 22.04. The Cosmic desktop in POP OS 22.04 features GNOME 42 at its core. But it is heavily stripped-down to align with Cosmic desktop principles.
|
||||
|
||||
The GNOME Shell version is 42 with a mixture of applications versions. For instance, the look and feel remained almost the same as earlier releases of Pop OS, such as the buttons, colour pallets, rounded corners, menus, etc. In the same way, this LTS version has Gedit 41.0 – that means the new GNOME Text editor is not included, nor is the new GNOME Terminal.
|
||||
|
||||
Files 42 in this release look almost the same as earlier versions. However, the Files get its latest version, 42, with all of its core features, not the looks. For example, the stock Files 42 has new folder icons, compact spacing of widgets and new menus. But the Files 42 in Cosmic desktop retained its own folder icons and colours.
|
||||
|
||||
![Files in Pop OS 22.04][3]
|
||||
|
||||
In addition to that, the newly designed Dark, Light theme support with auto wallpaper change is not picked up. Because Pop OS already had the Light/Dark theme support for quite some time since the inception of the Cosmic Desktop.
|
||||
|
||||
Another critical application GNOME Settings (gnome-control-center) version remained at 41.1, which means the massive uplift of the Settings app with GNOME 42, is not available with additional features. Clearly, it is understandable from the Pop OS team’s decision because the gnome-control-center version 42 is a complex converted application to libadwaita and GTK4 with many features. Some of those features are built-in in the Pop OS via different means (such as the Light/Dark theme switcher).

Apart from this, there are no other significant changes in the Pop OS installer. Although Ubuntu 22.04 LTS uses Linux Kernel 5.15, Pop OS 22.04 LTS have the Linux Kernel 5.16.
|
||||
|
||||
I could not find a changelog published, so I assumed these were the visible changes that caught my eye.
|
||||
|
||||
### How to download Pop OS 22.04?
|
||||
|
||||
I would recommend you not do an upgrade at this time. Because of the BETA ISO image which I tried, it is extremely buggy. There are many boot problems, installation failure, updates breaking the boot process and Cosmic desktop freeze problems.
|
||||
|
||||
So, when I took a look at the [GITHUB BETA issue list][4], I was confident that it’s not yet stable, being a BETA copy. And to write this article, I had to spend a couple of hours getting it installed in [virt-manager.][5] Because the first time it got installed perfectly, I did an upgrade, and it broke the installation. So I had to re-install again.
|
||||
|
||||
That said, if you still want to test, get a hands-on or contribute to the testing, download the ISO image from the link down below. You can try it in a virtual machine or a physical system. But prepare yourself for some issues and report them when you find any.
|
||||
|
||||
#### Release timeline?
|
||||
|
||||
Well, Pop OS follows their releases after the stable release of Ubuntu. Therefore, an optimistic release timeline should be after April 21, 2022. Looking at the past release history, the Pop OS 22.04 should release between May and June 2022 as a stable release.
|
||||
|
||||

EndeavourOS Apollo Release Introduces a new Worm Window Manager
|
||||
======
|
||||
|
||||
EndeavourOS is an Arch-based distro that focuses on a terminal-centric user experience along with all the other goodies.
|
||||
|
||||
With its latest Apollo release, the EndeavourOS team has made efforts to improve the community editions, resolve some existing issues, and add a new window manager.
|
||||
|
||||
### EndeavourOS Apollo: What’s New?
|
||||
|
||||
The most significant changes include a brand-new Window Manager “Worm” and having FirewallD installed (and enabled) by default.
|
||||
|
||||
Let us take a brief look at the changes along with other improvements.
|
||||
|
||||
#### New Worm Window Manager
|
||||
|
||||
![][1]
|
||||
|
||||
Worm is a lightweight window manager developed by one of the community editions team members (Codic12). It is written in [Nim][2].
|
||||
|
||||
Presently, it is based on X11 and does not support Wayland.
|
||||
|
||||
The window manager focuses on performance while being able to work with floating/tiling modes with essential window decorations that include minimize, maximize, and close buttons.
|
||||
|
||||
The layout can even operate nicely on a semi-embedded device like Pi Zero.
|
||||
|
||||
#### Linux Kernel 5.17
|
||||
|
||||
[Linux Kernel 5.17][3] is all about supporting next-gen hardware. If you are looking to try an Arch-based distro on the latest hardware configuration, EndeavourOS should be a nice option to start with.
|
||||
|
||||
#### FirewallD Installed and Enabled
|
||||
|
||||
![][4]
|
||||
|
||||
While not everyone appreciates having a firewall enabled by default, with the latest Apollo release, EndeavourOS will have it baked in and active after installation.
|
||||
|
||||
#### New Quickstart App
|
||||
|
||||
![][5]
|
||||
|
||||
A GUI app to launch after the first boot (quickstart) was added to help you choose/install common and helpful apps.
|
||||
|
||||
It provides the selection of applications using the Arch repo and not the [AUR][6].
|
||||
|
||||
#### A New Nvidia Driver Installer
|
||||
|
||||
The existing nvidia-installer-dkms app was rewritten as an improved command-line tool to make the process easier and more efficient.
|
||||
|
||||
The tool is still in its beta phase, but it is a good addition for users with Nvidia graphics.
|
||||
|
||||
#### Improvements to the Installer
|
||||
|
||||
Various improvements to the installation process were made, like the addition of an internet check before installation, a fix for DE selection, and more technical work to improve the experience.
|
||||
|
||||
#### Other Improvements
|
||||
|
||||
![][7]
|
||||
|
||||
Along with the key highlights, there are plenty of important fixes and changes that include:
|
||||
|
||||
* Disable Bluetooth by default, but active in the Live environment.
|
||||
* Applying compression on installed files for btrfs.
|
||||
* Community editions with dedicated display manager, including Light DM, Slick greeter, Lxdm, ly, and GDM.
|
||||
* Automatically choosing the closest EndeavourOS mirror.
|
||||
|
||||
|
||||
|
||||
You can learn more about the latest release in their [official announcement][8].
|
||||
|
||||
### Download EndeavourOS Apollo
|
||||
|
||||
The latest ISO is available on their official website. You can head to the [downloa][9][d][9] [page][9] and get the ISO from one of the mirrors available.

Ubuntu MATE 22.04 – New Features and Release Details
|
||||
======
|
||||
A LIST OF NEW FEATURES OF THE UBUNTU MATE 22.04 LTS (JAMMY JELLYFISH)
|
||||
THAT INCLUDES WHAT CHANGED SINCE THE PRIOR LTS RELEASE.
|
||||
![Ubuntu MATE 22.04 LTS Desktop][1]
|
||||
|
||||
### Ubuntu MATE 22.04 LTS – New Features
|
||||
|
||||
Ubuntu MATE 22.04 LTS “Jammy Jellyfish” releases on April 21, 2022, with the developers’ two years’ worth of continuous work.
|
||||
|
||||
While looking at the changes in Ubuntu MATE 22.04 LTS, I was surprised to see the number of changes it brings compared to the other official Ubuntu flavours, excluding KDE Plasms while based on [Ubuntu 22.04 LTS][2].
|
||||
|
||||
The primary reason is that Ubuntu MATE 22.04 LTS brings the latest , a major version upgrade since Ubuntu MATE 20.04 featuring MATE Desktop 1.24.
|
||||
|
||||
In addition to that, this is a first point release of the MATE desktop environment, which means you are bound to experience the performance boost because bugs and memory leaks are eliminated.
|
||||
|
||||
While trying the available ISO, I felt the is fantastic. It is super fast in terms of responses on the desktop. Thanks to the great work done by the MATE desktop team.
|
||||
|
||||
![Such a nice and clean login screen of Ubuntu MATE 22.04 LTS][3]
|
||||
|
||||
#### Themes and other changes
|
||||
|
||||
Moreover, this LTS release is the first variant that officially launches the with all the Yaru colour themes plus the native “Chelsea cucumber” green version. And it looks stunning.
|
||||
|
||||
Furthermore, the team also included dark and light app indicators of popular applications in the system tray, which automatically changes appearance when you transition from dark to light theme or vice-versa.
|
||||
|
||||
![MATE variant of Yaru themes][4]
|
||||
|
||||
This release includes three new GNOME applications due to popular demand: . Interestingly, they are GNOME apps based on the 41.0 release and they look stunning in the MATE environment considering they are using GTK4 and libadwaita.
|
||||
|
||||
[][5]
|
||||
|
||||

|
||||
|
||||
Besides those, the team included all popular package formats by default in the installation. That means , and you do not need to play around to set them up the first time.
|
||||
|
||||
Finally, this release brings back the message indicators with 22.2.0 in the default installation. Ayatana Indicators now supports backwards compatibility to Ubuntu indicators and doesn’t require additional setup.
|
||||
|
||||
Last but not least, a colossal set of impactful tiny changes, under the hood improvements and application updates makes it one of the most memorable releases from the Ubuntu MATE team.
|
||||
|
||||
### Summary of the changes

Razer and Lambda Team Up to Unveil a Linux Laptop for Deep Learning
|
||||
======
|
||||
|
||||
Razer is known for its gaming peripherals and hardware.
|
||||
|
||||
On the other hand, Lambda offers workstations, servers, and GPU clusters equipped with their software stack to facilitate deep learning as conveniently as possible.
|
||||
|
||||
They have collaborated to present a sleek-looking modern laptop (powered by Ubuntu 20.04) tailored for deep learning on the go.
|
||||
|
||||
And, it isn’t like any [other Linux laptops][1] available.
|
||||
|
||||
In case you are curious, deep learning is a type of machine learning where you teach a computer to process information similar to how humans do (by example). You can explore [Wikipedia][2] for more details.
|
||||
|
||||
### Tensorbook: The Deep Learning Laptop
|
||||
|
||||
![][3]
|
||||
|
||||
The Tensorbook is a Linux-powered laptop with state-of-the-art specifications to help you efficiently work with deep learning training/development anywhere. And, Lambda’s software stack supports all the tools to conveniently update PyTorch, Tensorflow, CUDA, etc., with just a single command.
|
||||
|
||||
Of course, the name isn’t a surprise, considering tensor cores help speed up the machine learning training/process.
|
||||
|
||||
![][4]
|
||||
|
||||
Razer did not add any of their usual signature patterns with this laptop, like a green accent/color, logo, or RGB elements. Well, for the greater good, this is tailored for deep learning. So, it is only fair that it isn’t too flashy.
|
||||
|
||||
You only find the lambda logo as the primary on the lid and a Razer x Lambda text on the bottom bezel of the screen. And, the purple accent goes all over, Lambda taking the lead on its branding here.
|
||||
|
||||
The specifications for the laptop involve:
|
||||
|
||||
* **GPU**: GeForce RTX 3080 Max-Q 16 GB VRAM
|
||||
* **CPU:** Intel i7-11800H
|
||||
* **RAM:** 64 GB 3200 MHz DDR4
|
||||
* **Storage:** 2 TB NVMe PCIe 4.0
|
||||
* **Display:** 165 Hz 1440p 15.6-inch
|
||||
|
||||
|
||||
|
||||
In addition to the solid core configuration, the connectivity options include:
|
||||
|
||||
* 3 x USB 3.2 Gen 2 Type-A ports
|
||||
* 1 x HDMI 2.1
|
||||
* 1 x UHS-III SD Card Reader
|
||||
* 3.5 mm Headphone/Microphone jack
|
||||
* 2 x Thunderbolt 4 ports
|
||||
* Wi-Fi 6E
|
||||
* Bluetooth 5.2
|
||||
|
||||
|
||||
|
||||
Undoubtedly, the laptop is a sleek powerhouse with all the components packed in it.
|
||||
|
||||
The RTX 3080 GPU should be capable enough to help with your deep learning tasks, whether you are a professional or a beginner.
|
||||
|
||||
Of course, it isn’t pitched for gaming, but with what you have, along with a high refresh rate screen, you can comfortably game on it when you want.
|
||||
|
||||
![][5]
|
||||
|
||||
The machine learning training benchmarks claim that it is way ahead of the M1 Max chip.
|
||||
|
||||
So, you will not have any trouble with training models.
|
||||
|
||||
### Pricing and Availability
|
||||
|
||||
It is a premium offering, so the price tag suits the same, starting at **$3499**. You can customize it for enterprise settings to pack in Windows 10 and Ubuntu.
|
||||
|
||||
An extended warranty and premium support is available if you want to pay the extra.
|
||||
|
||||
You can customize and proceed with the purchase on Lambda’s official website.

Ubuntu Budgie 22.04 LTS – New Features and Release Details
|
||||
======
|
||||
A LIST OF NEW FEATURES IN THE UBUNTU BUDGIE 22.04 LTS RELEASE.
|
||||
Ubuntu Budgie is the official Ubuntu flavour that features the Budgie Desktop Environment. It is uniquely designed to give you an alternative desktop experience while depending upon the GNOME stack. Written in C and Vala, the Budgie desktop uses GTK 3.x series for its components.
|
||||
|
||||
![Ubuntu Budgie 22.04 LTS Desktop][1]
|
||||
|
||||
### Ubuntu Budgie 22.04 LTS – New Features
|
||||
|
||||
[Ubuntu 22.04 LT][2]S is the base for Ubuntu Budgie 22.04 LTS, which features the [Linux Kernel 5.15 LTS][3] and underlying base packages. The Linux KErnel 5.15 brings proper support for all the latest CPU, GPU and SoC lineup from the popular manufacturers. Let’s take a look at the Budgie core improvements in this release.
|
||||
|
||||
Firstly, this release brings the latest Budgie 10.6 series which brings several improvements since the last LTS version of Ubuntu Budgie. The major changes include the budgie-indicator-applet, which has now swapped to support ayatana-indicators. Also, ayatana-indicator-applet and ayatana-webmail installation are now possible, supporting desktop notification integration with Evolution and Thunderbird email client.
|
||||
|
||||
Secondly, the system tray now looks more professional with proper spacing between the icons, and the app indicator is now shown at the beginning of the system tray.
|
||||
|
||||
In addition to that, the GNOME Control Center (settings) is now hidden from the main menu, and the Budgie Control Center replaces it. The Budgie control centre was introduced in version 10.6 onwards, and it gives you the necessary options to configure Budgie desktop components.
|
||||
|
||||
Moreover, the desktop layout and appearance get updated WhiteSur icon and GTK themes, GTK4+ compatible Arch themes and the Pocillo icon theme. All the underlying icons and layout themes match with their latest upstream version in this release.
|
||||
|
||||
Furthermore, the important Budgie Welcome tool now features both Brave browser and Microsoft Edge as an option to install. And a new Chrome OS desktop layout is available in this release for those who like the Chrome OS layout.
|
||||
|
||||
![New Chrome OS Layout in Ubuntu Budgie 22.04 LTS][4]
|
||||
|
||||
One of the interesting changes in this release is related to the Firefox web browser. Recently Ubuntu made the transition to Firefox Snap instead of the deb version. So, Budgie also removed the deb version of Firefox from this release and added the snap version. But also, Canonical’s Firefox ESR (extended support release) PPA is now a browser option for all supported releases.

||||

||||

|
||||
|
||||
Finally, a few stunning default wallpaper and the inclusion of the Mesa 22 3D graphics layer make it a somewhat interesting release of Ubuntu Budgie.
|
||||
|
||||
### Summary and Download
|
||||
|
||||
Here is a quick recap and summary of the changes with applications.
|
||||
|
||||
* Linux Kernel 5.15 LTS
|
||||
* Budgie Desktop 10.6.1
|
||||
* Budgie Control Center instead of GNOME Control Center
|
||||
* New Chrome OS Layout
|
||||
* Updated Themes and Icons to match their upstream versions
|
||||
* Cosmetic changes to the top panel
|
||||
* Firefox Snap replaces Firefox deb (with Firefox ESR PPA as an alternative)
|
||||
* Mesa 22
|
||||
|
||||
|
||||
* Firefox 99.x
|
||||
* LibreOffice 7.3.x
|
||||
* Nemo File Manager 5.2.4
|
||||
* Tilix Terminal 1.2.4
|
||||
* Gedit text editor 41.0
|
||||
* RISCV64 architecture support from this release
|
||||
|
||||
|
||||
|
||||
Last but not the least, this may be the last Ubuntu Budgie LTS release with the Budgie desktop as the team may move to EFL desktop in the coming years which you can [read here.][5] But I guess this official flavour will continue to serve users via a fork.
|
||||
|
||||
Overall, a moderate long term support release considering the above new features and updates. Ubuntu Budgie 22.04 LTS is available to download using the below link as Beta. You may want to give it a try before the final release.

Elon Musk Believes Twitter Algorithm Should Be Open-Source
|
||||
======
|
||||
|
||||
So, Elon Musk made it to the news again, as usual.
|
||||
|
||||
However, this time, it was very interesting. He made an offer to buy Twitter for about **$43 billion.**
|
||||
|
||||
Technically, he offered way more than the market price in a bid to acquire Twitter, which is why many outlets have claimed it as an attempt at a “hostile takeover”.
|
||||
|
||||
While that may or may not succeed, considering the aggressive offer. At a TED talk, Elon Musk also shared some of his thoughts on how Twitter should move forward to promote free speech.
|
||||
|
||||
### Twitter Algorithm Should be Open-Source
|
||||
|
||||
Elon Musk believes that Twitter should open-source the algorithm to promote transparency in the platform.
|
||||
|
||||
Of course, Twitter as a platform is exploding and unpredictable at the moment. The Twitter team also takes quick actions on certain matters, whether you think it is right or wrong.
|
||||
|
||||
While Twitter’s internal decisions could sound good on paper, there are always issues with such massive platforms without transparency.
|
||||
|
||||
So, Elon Musk might have a point here. Whether you believe or trust Twitter’s decision, transparency/open-source will only help strengthen the existing values.
|
||||
|
||||
Well, no wonder, we love open-source here.
|
||||
|
||||
To quote his words, he mentions:
|
||||
|
||||
> “_And so one of the things that I believe Twitter should do is open-source the algorithm and make any changes to people’s tweets, if they’re emphasized or de-emphasized, that action should be made apparent so anyone can see that action has been taken. So, there’s no sort of behind-the-scenes manipulation, either algorithmically or manually_“
|
||||
|
||||

|
||||
|
||||
> How would Elon Musk change Twitter if he were to buy it? First, he’d make it open source. Watch [@ElonMusk][1]’s wide ranging live [#TED2022][2] interview with [@TEDChris][3] on [@YouTube][4] here: <https://t.co/dFFUxNqLZe> [pic.twitter.com/Okm3y5HpEy][5]
|
||||
>
|
||||
> — TED Talks (@TEDTalks) [April 14, 2022][6]
|
||||
|
||||
On the other side, when we talk about Twitter as an open-source platform in some way, I can’t stop thinking about [Mastodon][7]. You can also find us on [Mastodon][8], if you haven’t explored it yet.
|
||||
|
||||
Sure, Twitter has a lot of growth potential and it is constantly expanding for better or worse. But, can the concept of open-source help the platform? Personally, I think yes, but it is too big a change to expect overnight.
|
||||
|
||||
Of course, no one can predict Elon Musk’s future actions for Twitter either, even if he manages to acquire it. Honestly, he’s just as unpredictable as any complex algorithm.
|
||||
|
||||
_So, what would be your take on this? Do you believe what Elon Musk has to say? Feel free to share your thoughts in the comments down below._

Lubuntu 22.04 LTS – New Features and Release Details
|
||||
======
|
||||
A LIST OF NEW FEATURES AND IMPROVEMENTS IN THE LUBUNTU 22.04 LTS
|
||||
RELEASE.
|
||||
Lubuntu is the LXQt-based Linux Distribution based on Ubuntu Linux. It is one of the super lightweight distros that brings both worlds’ power. With Lubuntu 22.04, you get the latest Ubuntu tech with a lightweight desktop environment. A perfect combination if you still favour the legacy desktops.
|
||||
|
||||
![Lubuntu 22.04 LTS Desktop – isn’t it nice and clean][1]
|
||||
|
||||
### Lubuntu 22.04 – New Features
|
||||
|
||||
The Lubuntu 22.04 LTS based on Ubuntu 22.04 LTS, which features the Linux Kernel 5.15 LTS. The Linux Kernel 5.15 LTS brings the underlying Kernel support for the latest line of the hardware across processors, GPU and ARM chips. It also brings performance improvements across kernel modules and the secure and stable kernel to date.
|
||||
|
||||
Perhaps the vital change in Lubuntu 22.04 LTS is the latest [LXQt desktop version 0.17][2] (based on Qt 5.15). If you are a Lubuntu 20.04 Focal Fossa user, then you should notice significant changes in LXQt 0.17 compared to LXQt 0.14 from Focal Fossa. It is worth mentioning here that [LXQt 1.0.0][3] is the current stable release, and it will not be featured in this version due to schedule and planning mismatch.
|
||||
|
||||
Firstly, LXQt 0.17 brings PCManFM-Qt 0.17, which brings a few changes such as displaying the creation time of files, options to create launchers and shortcuts from the menu and a fix for blurred thumbnails.
|
||||
|
||||
![Creation time][4]
|
||||
|
||||
![Launcher option and root instance in File Manager][5]
|
||||
|
||||
Secondly, the LXQt power manager improves the idle watchers with separate AC and batter options.
|
||||
|
||||
Other than that, the LXQt panel can not behave like a dock with an auto-hide feature when overlapped with the application window.
|
||||
|
||||
![Autohide in LXQt 0.17][6]
|
||||
|
||||
In addition, LXImage Qt image viewer brings “autofit” features when browsing images, a new thumbnail option in settings. Also many more bug fixes across the LXQt desktop in version 0.17, which lands in Lubutnu 22.04 LTS.
|
||||
|
||||

|
||||
|
||||
Moreover, the default Browser is the Firefox Snap version, resulting in little slowness on this fast desktop. But it is completely a workload and hardware dependent. What I mean is, you may not feel Firefox Snap is slow in the latest Intel or AMD processor lineup, but it would feel slower compared to the Firefox deb version.
|
||||
|
||||
Furthermore, Lubuntu 22.04 brings the Calamares installer (not the default Ubuntu installer) and adds the KDE Plasma’s Discover software manager. I believe these two are an excellent addition to this release and going to help users.
|
||||
|
||||
Finally, an awesome default wallpaper featuring the official “Jammy Jellyfish” mascot enriches the overall Lubuntu desktop experience.
|
||||
|
||||
### Summary and Download
|
||||
|
||||
With that said, here is a summary of the applications and packages in Lubuntu 22.04 LTS.
|
||||
|
||||

|
||||

Kubuntu 22.04 LTS Arrives with KDE Plasma 5.24
|
||||
======
|
||||
|
||||
Ubuntu 22.04 LTS has finally been released. So, you can expect all of its official flavors to offer the latest and greatest soon after that.
|
||||
|
||||
And, the KDE flavour, i.e., Kubuntu 22.04 LTS is now also available to download!
|
||||
|
||||
You should expect all the [feature additions of Ubuntu 22.04 LTS][1] and specially tailored improvements for the Kubuntu 22.04 release.
|
||||
|
||||
Let me briefly emphasize the key changes.
|
||||
|
||||
### Kubuntu 22.04 LTS: What’s New?
|
||||
|
||||
The primary highlight of the release is KDE Plasma 5.24 LTS.
|
||||
|
||||
In addition to that, you should also notice updates to KDE apps and other pre-installed applications. Let’s take a look:
|
||||
|
||||
#### KDE Plasma 5.24
|
||||
|
||||
![][2]
|
||||
|
||||
KDE Plasma 5.24 features an updated breeze theme, and several visual improvements. It is a long-term supported version that should get updates until Plasma 6 releases.
|
||||
|
||||
You had the option to use KDE Neon or Arch Linux, or a few other distros to experience KDE Plasma 5.24. Finally, Kubuntu is here as a mainstream distro featuring the latest and greatest from KDE.
|
||||
|
||||
You can learn more about [KDE Plasma 5.24][3] changes in our previous coverage.
|
||||
|
||||
If you are moving away from GNOME-based Ubuntu, you may want to check out our article on [KDE Plasma vs GNOME][4] to get some insights before making the switch.
|
||||
|
||||
#### Default Browser as Firefox Snap
|
||||
|
||||
Firefox 99 snap is the default browser. In case you’re curious, Mozilla is working with Canonical to quickly push updates and conveniently maintain the browser using the snap package.
|
||||
|
||||
So, it only makes sense to keep it as the default. But, you can always install the deb package if you do not prefer using Snap.
|
||||
|
||||
#### GNOME-like Overview
|
||||
|
||||
With KDE Plasma 5.24, you get the ability to use a feature similar to GNOME’s Activities overview.
|
||||
|
||||
You can browse through your virtual desktops and windows at a glance with its help.
|
||||

|
||||
#### Improvements to Discover
|
||||
|
||||
![][6]
|
||||
|
||||
The software center for KDE i.e. Discover has received some upgrades. One of the neat additions includes the ability to prevent removing anything that is critical to the system’s operation.
|
||||
|
||||
You should notice a warning when you try to remove something that could break the system.
|
||||
|
||||
If you prefer Flatpak, you can now open locally downloaded Flatpak packages and install it using the Flatpak repository URI.
|
||||
|
||||
#### Fingerprint Support
|
||||
|
||||
KDE Plasma 5.24 finally adds the support for fingerprint authentication. You can conveniently add up to 10 fingerprints and use them to unlock or authenticate something.
|
||||
|
||||
#### Other Improvements
|
||||
|
||||
![][7]
|
||||
|
||||
In addition to the major upgrades, you should expect subtle changes across the platform along with app updates that include:
|
||||
|
||||
* LibreOffice 7.3
|
||||
* KDE Gear 21.12
|
||||
* Dolphin
|
||||
|
||||
|
||||
|
||||

Ubuntu Budgie 22.04 LTS Released: Fast, Elegant, And More Feature-Filled Than Ever
|
||||
======
|
||||
|
||||
Since its initial release in 2016, I’ve been an admirer of Ubuntu Budgie. With its sleek visuals, fluid animations, and solid Ubuntu base, it covers all my needs.
|
||||
|
||||
Although it is relatively new compared to other Ubuntu flavors, it has already managed to gain a significant following.
|
||||
|
||||
Now, with Ubuntu Budgie 22.04 LTS, this level of polish has been brought to a whole new level.
|
||||
|
||||
### What’s New?
|
||||
|
||||
![][1]
|
||||
|
||||
As to be expected, there are vast numbers of improvements compared to the previous 20.04 LTS release. Some changes include:
|
||||
|
||||
* The newly released [Budgie 10.6][2]
|
||||
* budgie-applications-menu-applet improvements
|
||||
* New hot corners “delay” and “pressure” options
|
||||
* Panel spacing improvements
|
||||
* RISCV64 support
|
||||
* Theme updates from upstream
|
||||
* New Chrome OS-like layout
|
||||
|
||||
|
||||
|
||||
You can expect updates for Ubuntu Budgie 22.04 up until 2025.
|
||||
|
||||
#### Budgie 10.6 Desktop
|
||||
|
||||
![][3]
|
||||
|
||||
Ubuntu Budgie 22.04 now ships with Budgie 10.6. As I highlighted in [our coverage][2] of the release, it is the first one under its new organization. In short, Joshua Strobl left the Solus distribution but still wanted to work on Budgie.
|
||||
|
||||
![][4]
|
||||
|
||||
To facilitate this, he forked the Budgie repository and formed the **Buddies of Budgie** organization, which now maintains and develops budgie.
|
||||
|
||||
Due to all of these changes, Budgie 10.6 wasn’t a massive release, although it did bring a new notification system, alongside some minor code reformatting. As a result, other Budgie components can now use the notification system, opening up some interesting future options.
|
||||
|
||||
![][5]
|
||||
|
||||
Of course, Ubuntu Budgie 22.04 inherits these changes, and it will be interesting to see what they do with them in future releases.
|
||||
|
||||
#### App Menu Improvements
|
||||
|
||||
![][6]
|
||||
|
||||
Ubuntu Budgie 22.04 also has a few improvements to the application menu. One of my favorite features of the app menu is its fast search, which has now been improved. This comes in the form of the availability of the app context menu in the search results.
|
||||
|
||||
Additionally, the menu now also supports the non-default GPU flag from .desktop files. This is particularly useful for laptop users, as it allows simpler apps to use significantly less power. This is extended with a new context menu option, which allows users to easily change this option in the GUI.
|
||||
|
||||
Finally, the categories should now be more inclusive, meaning, fewer apps end up in the “**Other**” category.
|
||||
|
||||
As a laptop user, I have really been enjoying the extra battery life these changes have afforded me, and I’m sure many of you will appreciate these changes too.
|
||||
|
||||
#### RISC-V Support
|
||||
|
||||
This improvement is extremely exciting. For those of you that are unaware, RISC-V is a fully open-source CPU architecture (think x86 and ARM) that is slowly becoming quite popular. As such, it is only a matter of time before we find these CPUs making their way into desktops and laptops (like what we have seen with ARM chips).
|
||||
|
||||
For this, Ubuntu Budgie now has support for this exciting architecture, although there is no pre-built disk image available. Instead, Ubuntu Server must be installed first, with the user than installing the `ubuntu-budgie-desktop` package.
|
||||
|
||||
Although the installation process is not for new users, this addition paves the way for support for the next generation of CPUs.
|
||||
|
||||
#### Theme Updates
|
||||
|
||||
![][7]
|
||||
|
||||
Another major highlight in Ubuntu Budgie 22.04 is the numerous theme updates. Firstly, the beautiful Arc theme has been updated with GTK 4 support, ready for apps transitioning from GTK 3. Of course, this doesn’t affect Libadwaita apps, which you can read about why in our [in-depth coverage][8].
|
||||
|
||||
![][9]
|
||||
|
||||
The WhiteSur GTK and icon themes have been updated for macOS fans, with support for more apps and more accurate visuals.
|
||||
|
||||
Finally, the default Pocillo theme has been updated with more app icons.
|
||||
|
||||
You can learn more about the technical changes in the [official release notes][10].
|
||||
|
||||
### Getting Ubuntu Budgie 22.04
|
||||
|
||||
For the first time, you might want to try Ubuntu Budgie 22.04 on a virtual machine to see how it goes.
|
||||
|
||||
If you already have Ubuntu Budgie installed, upgrading is extremely simple. Simply copy the following command into the terminal, and follow the on-screen prompts. You may have to wait for a few days if the upgrade isn’t available yet.
|
||||
|
||||
```
|
||||
|
||||
sudo do-release-upgrade -d -f DistUpgradeViewGtk3
|
||||
|
||||
```
|
||||
|
||||
For new users, just download the ISO file from the button below.
|
||||
|
||||
[Get Ubuntu Budgie 22.04 LTS][11]
|
||||
|
||||
Overall, Ubuntu Budgie is a great upgrade to an already awesome distro. Between the updated budgie version, RISC V support, and theme updates, Ubuntu Budgie continues to be a competitive alternative to other Ubuntu flavors.

Ubuntu MATE 22.04 LTS Brings in a New Yaru Theme, MATE Desktop 1.26.1, and More Improvements
|
||||
======
|
||||
|
||||
Ubuntu 22.04 LTS is an exciting release already.
|
||||
|
||||
While other Ubuntu-based distros should be getting ready to offer their latest versions based on Ubuntu 22.04 LTS, Ubuntu’s official flavors’ LTS releases have also landed.
|
||||
|
||||
Here, we focus on **Ubuntu MATE 22.04 LTS**, featuring the latest MATE Desktop 1.26.1.
|
||||
|
||||
Usually, Ubuntu MATE 22.04 LTS puts great effort on top of the improvements from the upstream.
|
||||
|
||||
This time, it has received significant updates, especially to the look/feel.
|
||||
|
||||
### Ubuntu Mate 22.04: What’s New?
|
||||
|
||||
Ubuntu Mate 22.04 brings quite a number of changes to the appearance apart from necessary packages updates and bug fixes.
|
||||
|
||||
Let’s take a look at the major highlights.
|
||||
|
||||
#### 1\. Improved Yaru Theme Support
|
||||
|
||||
Ubuntu’s popular and community-backed default theme takes the center stage in this release. MATE’s compatibility with the theme has been significantly improved since it was first included in Ubuntu MATE 21.04.
|
||||
|
||||
Now, all the Yaru color accents have been shipped, along with a new MATE-focused “Chelsea Cucumber” theme. The stock and the legacy Ambiant/Radiant themes have been removed.
|
||||
|
||||
![Source: Ubuntu MATE][1]
|
||||
|
||||
When upgrading to the new version, an automatic settings migration takes care of selecting a relevant Yaru MATE theme if your old theme is no longer supported.
|
||||
|
||||
MATE’s default Windows Manager – Metacity or Marco – has also been updated to provide a uniform look and feel. This applies to third-party compositors too.
|
||||
|
||||
#### 2\. Improved Panels
|
||||
|
||||
Expanding on the Yaru compatibility, the Appearance Control Center now accurately switches the color scheme for apps. The panel now comes in both light and dark mode, along with a host of panel icons to Yaru.
|
||||
|
||||
The theming brings support to Plank and Pluma too.
|
||||
|
||||

|
||||
|
||||
#### 3\. Updated Ayatana Indicators
|
||||
|
||||
Ubuntu MATE 20.10 users must be familiar with Ayatana Indicators. For those unaware, they are basically a fork of Ubuntu indicators and created to be used across many distros and desktop environments.
|
||||
|
||||
![Source: Ubuntu MATE][4]
|
||||
|
||||
Ayatana Indicators 22.2.0 has been included in this new release. This means there’s less RAM and CPU usage, leading to improved battery performance and backward compatibility with Ubuntu Indicators.
|
||||
|
||||
#### 4\. MATE Tweak
|
||||
|
||||
One of the most popular features of Ubuntu MATE is the presence of MATE Tweak which allows users to select their preferred desktop layout ranging from Cupertino (macOS) to Redmond (Windows 10).
|
||||
|
||||
Users should now expect an improved layout switching and restoring for custom layouts.
|
||||
|
||||
![Source: Ubuntu MATE][5]
|
||||
|
||||
Also, those who make use of third-party compositors should expect better support. Do note that support for Compton has been dropped (since it’s not maintained anymore) and support for picom has been added instead.
|
||||
|
||||
Lastly, the mate-netbook layout has been removed due to conflicting issues with client-side decorated windows.
|
||||
|
||||
#### 5\. MATE HUD
|
||||
|
||||
MATE HUD is a custom HUD that makes use of rofi to run menu commands.
|
||||
|
||||
It has been updated to support the latest version of rofi, as a new theme engine has been introduced. Also, the window now sports rounded corners, depending on the current GTK theme.
|
||||
|
||||
Users can also add their own rofi themes by pasting them in:
|
||||
|
||||
`~/.local/share/rofi/themes`.
|
||||
|
||||
#### 6\. New Apps and Packages
|
||||
|
||||
Users will be pleased to know that support for PPA, Snap, AppImage, and Flatpak has been enabled by default.
|
||||
|
||||
The snap-desktop-integration has also been included to improve the user’s session and automatically install snapped themes.
|
||||
|
||||
GNOME users will particularly be pleased to see three new GNOME apps—Maps, Clocks, and Weather.
|
||||
|
||||
![Source: Ubuntu MATE][6]
|
||||
|
||||
Not to forget, you should also expect the latest [Firefox 99.0][7], Celluloid 0.20, Evolution 3.44, LibreOffice 7.3.2.1, and Blueman 2.2.4, among other package updates.
|
||||
|
||||
#### 7\. Linux Kernel 5.15 LTS and Mate Desktop 1.26.1
|
||||
|
||||
You can expect the latest Linux Kernel 5.15 LTS release with Ubuntu MATE 22.04.
|
||||
|
||||
And, the desktop environment is now the latest MATE 1.26.1, which mostly includes performance and bug fixes on top of improvements to Mate Desktop 1.26.0.
|
||||
|
||||
#### 8\. Lighter ISO Size
|
||||
|
||||
Ubuntu MATE’s ISO size has been reduced to a decent 2.7 GB. So, what’s the take away?
|
||||
|
||||
Considering, that all of the legacy themes and icons have been removed. So, it’s safe to say, Ubuntu MATE’s theming system has completely transitioned to upstream Yaru. Furthermore, three snap-based applications have also been discarded.
|
||||
|
||||
Moreover, the proprietary NVIDIA graphics drivers can no longer be found in the default install.
|
||||
|
||||
Fret not, as a checkbox can be marked during the installation process to install third-party drivers to include NVIDIA drivers, just like some other Ubuntu-based distros. There’s even a minimal installation checkbox as well.
|
||||
|
||||
#### Other Changes
|
||||
|
||||
There have been several bug fixes and other additions as well.
|
||||
|
||||
* Bugs related to Plank, Brisk Menu, and a screen reader for visually-impaired users have been fixed.
|
||||
* Addition of 3 beautiful AI-generated wallpapers.
|
||||
* An updated Welcome screen with newer software.
|
||||
* Support for indicators for battery-powered gaming peripherals.
|
||||
* A new image for the Raspberry Pi.
|
||||
|
||||
|
||||
|
||||
You can have a look at the [official release notes][8] for detailed technical information.

### Closing Thoughts
|
||||
|
||||
Ubuntu MATE 22.04 is a feature-rich release with the main focus on visuals. Looks like community-driven Ubuntu MATE is now a more compelling alternative to Canonical’s Ubuntu, especially after noticing the inclusion of Yaru-only themes.

Xubuntu 22.04 LTS Releases with Updated Theme, Whisker Menu 2.7.1, and Other Upgrades
|
||||
======
|
||||
|
||||
Xubuntu is one of the most loved Ubuntu flavours featuring the Xfce desktop environment.
|
||||
|
||||
If you were looking to install the latest [Long-Term release][1] Ubuntu-based distro that is light on system resources, Xubuntu 22.04 should be a good pick.
|
||||
|
||||
Xubuntu 22.04 LTS includes a visual refresh and some package updates. Here, I shall highlight the key changes with this release.
|
||||
|
||||
### Xubuntu 22.04 LTS: What’s New?
|
||||
|
||||
Xubuntu 22.04 comes packed with new wallpapers, app upgrades, and more.
|
||||
|
||||
Some of the significant refinements include:
|
||||
|
||||
#### Theme Updates
|
||||
|
||||
![][2]
|
||||
|
||||
Greybird, the default theme for Xubuntu has introduced initial support for GTK 4 to blend in well with modern GTK applications.
|
||||
|
||||
It also brings back the Accessibility and Compact window manager themes.
|
||||
|
||||
![][3]
|
||||
|
||||
The elementary-xfce theme adds new icons and improves on the existing ones for a cleaner Xubuntu desktop experience.
|
||||
|
||||
#### New Wallpapers
|
||||
|
||||
Xubuntu features new default wallpapers along with six new additions from the community wallpaper contest.
|
||||
|
||||
![][4]
|
||||
|
||||
The new collection looks absolutely lovely.
|
||||
|
||||
#### Application Stack Updates
|
||||
|
||||
You should notice newer GNOME 42 applications, GTK 3.24.33, and other subsystem updates like NetworkManager 1.36, Mesa 22, PulseAudio 16, etc.
|
||||
|
||||
#### Xfce App Updates
|
||||
|
||||
![][5]
|
||||
|
||||
A range of Xfce applications have been updated with Xubuntu 22.04, some of the major ones include:
|
||||
|
||||
* **Mousepad 0.5.8**: A text editor with more features with support for session backup/restore, plugin support, and new plugins.
|
||||
* **Ristretto 0.12.2**: An image viewer with improved thumbnail support and performance improvements
|
||||
* **Whisker Menu Plugin 2.7.1**: More customization options
|
||||
|
||||
|
||||
|
||||
#### Firefox Snap
|
||||
|
||||
Just like Ubuntu 22.04, Xubuntu 22.04 includes Firefox as a snap package.
|
||||
|
||||
The snap package can be a secure experience with sandboxing and will get quicker updates by Mozilla.
|
||||
|
||||
### Other Improvements
|
||||
|
||||
You should expect numerous bug fixes and performance improvements along with the essential enhancements.
|
||||
|
||||
There are more package updates that include:
|
||||
|
||||
* Thunderbird 91
|
||||
* LibreOffice 7.3.2
|
||||
* Blueman 2.2.4
|
||||
* GNOME Disk Usage Analyzer 41.0
|
||||
* MATE Calculator 1.26.0
|
||||
* Thunar plugins
|
||||
|
||||
|
||||
|
||||
You can learn more about the changes in its [official announcement post][6].

Lubuntu 22.04 LTS Releases with Calamares Installer, LXQt 0.17.0, & Featherpad 1.0.1
|
||||
======
|
||||
|
||||
Looking for a lightweight Ubuntu distro for your computer as an alternative to GNOME-powered Ubuntu 22.04 LTS?
|
||||
|
||||
Lubuntu 22.04 LTS is here as a replacement. In fact, you can also take a look at [Xubuntu 22.04 LTS][1], if you are exploring lightweight options.
|
||||
|
||||
Here, we focus on the most exciting changes with Lubuntu 22.04 LTS.
|
||||
|
||||
### Lubuntu 22.04 LTS: What’s New?
|
||||
|
||||
Lubuntu 22.04 LTS comes packed with LXQt 0.17.0, updated applications, and some improvements.
|
||||
|
||||
It is a [Long-Term Release][2] version. So, you can expect updates for Lubuntu 22.04 LTS until 2025, i.e., **three-year support**, which is usual for [official Ubuntu flavours][3].
|
||||
|
||||
Some of the significant changes include:
|
||||
|
||||
#### New Wallpaper
|
||||
|
||||
Everyone loves a new wallpaper. With various Ubuntu flavours like [MATE][4], [Kubuntu][5], and [Budgie][6] releases, you have got plenty of new wallpapers.
|
||||
|
||||
With Lubuntu 22.04, there is an interesting wallpaper that you can find on [Unsplash][7]:
|
||||
|
||||
![][8]
|
||||
|
||||
#### LXQt 0.17.0 (Can Upgrade to LXQt 1.1.0)
|
||||
|
||||
While LXQt 0.17.0 includes essential improvements, it would have been more exciting to see the recent [LXQt 1.1.0][9]. Considering it was released last week, it did not make the cut in this release.
|
||||
|
||||
However, they could have gone with LXQt 1.0.0 at least.
|
||||
|
||||
![][10]
|
||||
|
||||
LXQt 0.17.0 includes improvements to the session behavior for non-LXQt apps, power manager updates, an auto-hide feature added to the LXQt panel, and further adjustments.
|
||||
|
||||
For details on LXQt 0.17.0, you can refer to its [official release notes][11].
|
||||
|
||||
The LXQt project team on Twitter [mentioned][12] that it is possible to easily install LXQt 1.1.0 on Lubuntu. I tried it on a virtual machine, so you can give it a try if you like.
|
||||
|
||||
![][13]
|
||||
|
||||
All you have to do is add the following repository and then upgrade the system:
|
||||
|
||||
```
|
||||
|
||||
sudo add-apt-repository ppa:severusseptimius/lxqt
|
||||
sudo apt update
|
||||
sudo apt upgrade
|
||||
|
||||
```
|
||||
|
||||
I did not have any issues with it. However, I am uncertain if Lubuntu recommends it yet (or they may push an update soon).
|
||||
|
||||
#### Firefox as Snap
|
||||
|
||||
Unfortunately, every Ubuntu flavour does include Firefox as a snap package, considering Mozilla will be focusing on the Snap for faster updates and maintenance.
|
||||
|
||||
In a good way, you should experience enhanced security with its sandboxing.
|
||||
|
||||
The release notes mention that the browser can be slower to start for the first time after boot, especially in the live environment. But you shouldn’t have trouble with subsequent runs.
|
||||
|
||||
#### Package Updates
|
||||
|
||||
With Lubuntu 22.04 LTS, you get upgrades to various applications that include:
|
||||
|
||||
* VLC 3.0.16
|
||||
* Featherpad 1.0.1
|
||||
* LibreOffice 7.3.2
|
||||
|
||||
|
||||
|
||||
Along with the applications, you also get an update to the Discover Software Center for a smoother experience with managing/installing software.
|
||||
|
||||
#### Calamares Installer
|
||||
|
||||
Lubuntu 22.04 LTS utilizes the Calamares installer in place of Ubiquity, as favored by most of the other Ubuntu flavours.
|
||||
|
||||
You get the swapfile size set to 512 MB by default. But, you can opt for no swap, if you like.
|
||||
|
||||
#### Dropping Trojita/k3b/fcitx
|
||||
|
||||
Some of the popular packages like Trojita (mail client), k3b, and fcitx are no longer present in Lubuntu 22.04 LTS.
|
||||
|
||||
So, if you are upgrading, you can manually install it using their [official guide][14].
|
||||
|
||||
To explore more about the changes in Lubuntu 22.04 LTS, you can refer to the [official release notes][15].
|
||||
|
||||
### Download Lubuntu 22.04 LTS
|
||||
|
||||
_If you are upgrading from Lubuntu 20.04 LTS that has LXQt, this new version uses a different Openbox settings configuration file._
|
||||
|
||||
_If you have customized, `~/.config/openbox/lxqt-rc.xml` you will want to copy that file to `~/.config/openbox/rc.xml`. This change does not impact new installations and upgrades from 21.10._
|
||||
|
||||
To perform a fresh installation, you can get the latest ISO from the official website (direct link/torrent available).

||||

Exciting New Features Revealed for KDE Plasma 5.25! Take a Look Here
|
||||
======
|
||||
|
||||
[KDE Plasma 5.24][1] was an interesting upgrade with an updated breeze theme and the new overview effect.
|
||||
|
||||
Now, the developers have geared up to introduce exciting new features for KDE Plasma 5.25.
|
||||
|
||||
### KDE Plasma 5.25: What’s New?
|
||||
|
||||
In a blog post by Nate Graham, some of the most intriguing changes were highlighted. Let us take a look at them here.
|
||||
|
||||
#### Ability to Selectively Apply the Global Theme
|
||||
|
||||
![Credits: Pointiestick Blog / Nate Graham][2]
|
||||
|
||||
When you proceed to apply a Global Theme from the system settings, you will be prompted to confirm if you want the theme to be applied everywhere or to certain parts of it.
|
||||
|
||||
For instance, you may not want to change the cursors and icons but the window background and application style.
|
||||
|
||||
Overall, you get more control when applying the Global Theme to your KDE-powered system.
|
||||
|
||||
Impressive work by **Dominic Hayes** for this [merged commit][3].
|
||||
|
||||
#### Auto-Generated Accent Based on Current Wallpaper
|
||||
|
||||
Having the ability to choose a custom or a preset accent is already good enough.
|
||||
|
||||
With KDE Plasma 5.25, they are getting one step ahead by giving the option to generate and select an accent color based on the current wallpaper.
|
||||
|
||||
And, it all happens automatically as you change the wallpaper, given that you have the option enabled.
|
||||
|
||||
You can find the option to enable it here:
|
||||
|
||||
![Credits: Pointiestick Blog / Nate Graham][4]
|
||||
|
||||
So, if you want something to match your background, you do not have to tweak around the custom accent colors to get it right. This should make things easier.
|
||||
|
||||
A small but mighty addition to the arsenal of new features. All thanks to **Tanbir Jishan** for this [merged commit][5].
|
||||
|
||||
#### Tint Color Scheme with Accent Color
|
||||
|
||||
For even greater customization to the look/feel, KDE Plasma 5.25 will let you add a tint to your selected accent color.
|
||||
|
||||
![Credits: Jan Blackquill][6]
|
||||
|
||||
You can enable/disable it if you like the user experience with the tinted theme.
|
||||
|
||||
To explore more about this change in the [merged commit][7] by **Jan Blackquill**.
|
||||
|
||||
#### Create Desktop Files for Flatpak/Snap Applications
|
||||
|
||||
Initially, sandboxed applications like Flatpak and Snap did not have the support for desktop files on KDE.
|
||||
|
||||
Thanks to a new **Dynamic launcher** portal (via [merged commit][8] by Harald Sitter). It allows you to create and edit .desktop files for seamless system integration with sandboxed applications.
|
||||
|
||||
#### Improvements to Discover
|
||||
|
||||
There are some subtle changes to the Discover software center where you can find all the application categories in the sidebar without needing to navigate through categories like “Applications”, “Add-ons”, and “Plasma Add-ons” separately.
|
||||
|
||||
KDE Discover Before vs After (Credits: **[Taavi Juursalu][9]**)
|
||||
|
||||
Use the cursor to slide through the before/after in the images above.
|
||||
|
||||
To explore more about the change, head to its [merged request][10].
|
||||
|
||||
#### Other Improvements
|
||||
|
||||
There are several other refinements and changes planned for KDE Plasma 5.25. Some of them include:
|
||||
|
||||
* Improvements to the performance of KRunner
|
||||
* Network widget adds details for frequency and BSSID of the Wi-Fi network
|
||||
|
||||
|
||||
|
||||
You can look at all the bug fixes and technical improvements in [Nate’s blog post][11].
|
||||
|
||||
_Exciting about KDE Plasma 5.25? Well, with these feature additions, I am eagerly awaiting its release. Let me know your thoughts in the comments below._

Pop!_OS 22.04 LTS Arrives with Automatic Updates, GNOME 42, and PipeWire
|
||||
======
|
||||
|
||||
The next LTS upgrade for Pop!_OS is finally here.
|
||||
|
||||
Pop!_OS 22.04 is based on Ubuntu 22.04 LTS with [Linux Kernel 5.16.19][1] at the time of launch.
|
||||
|
||||
Let us take a brief look at what it has to offer.
|
||||
|
||||
### Pop!_OS 22.04 LTS: What’s New?
|
||||
|
||||
Visually, it does not feature any massive changes. However, it does feature **GNOME 42** as its base for its COSMIC Desktop.
|
||||
|
||||
So, you should expect to see some [GNOME 42 features][2] available with Pop!_OS 22.04.
|
||||
|
||||
In addition to the desktop environment, there are a few new feature additions. I shall mention the key highlights as you read on.
|
||||
|
||||
#### Automatic Updates
|
||||
|
||||
With Pop!_OS 22.04 LTS, you can easily update/upgrade the system from the OS Upgrade & Recovery panel via the System settings.
|
||||
|
||||
![][3]
|
||||
|
||||
You can also schedule the day/time to process the upgrade. The scheduled automatic updates include support for Debian, Flatpak, and Nix packages as well. Surely, this should help save time by eliminating the need for checking updates every other day.
|
||||
|
||||
By default, you will be notified of the available updates on a weekly basis. But, you can tweak the settings to get notified every day or each month. The notifications will be turned off if you have automatic updates enabled.
|
||||
|
||||
![][4]
|
||||
|
||||
And, yes, the automatic updates are disabled by default. You will have to set it up if you require it.
|
||||
|
||||
#### New Support Panel
|
||||
|
||||
![][5]
|
||||
|
||||
Unlike other distributions, Pop!_OS tries to take a mainstream approach to provide technical support for users running the operating system.
|
||||
|
||||
To give clarity, they have added a new support panel in the settings where you can quickly access the documentation, join the community support, and create log files. These options should make the support options accessible, and encourage users to refer the recommended sources for quick support.
|
||||
|
||||
#### New Screenshot Tool
|
||||
|
||||
![][6]
|
||||
|
||||
Thanks to GNOME 42, you get the brand new screenshot UI with the ability to record the screen as well.
|
||||
|
||||
With Pop!_OS 22.04 LTS, I found the positioning of the UI a bit weird. And, it looks like they tweaked it a bit for a transparent look with slightly different icons.
|
||||
|
||||
#### Dark vs Light Backgrounds
|
||||
|
||||
![][7]
|
||||
|
||||
Unlike other distributions, you won’t find a new wallpaper collection to cater to the light/dark variants.
|
||||
|
||||
However, when you choose the light/dark theme, the wallpaper will change to the default light/dark variants available.
|
||||
|
||||
Do note that the light/dark mode can have independent backgrounds (you can change them) and isn’t locked to the default.
|
||||
|
||||
#### Improvements to the Pop!_Shop
|
||||
|
||||
The Pop!_Shop has received some significant performance upgrades along with subtle changes to offer a good user experience even with small window sizes.
|
||||
|
||||
![][8]
|
||||
|
||||
You will also find a new “**Recently Updated**” section to highlight the latest updated applications.
|
||||
|
||||
This should come in handy to find applications that have been recently updated with new features/fixes.
|
||||
|
||||
#### Improvements to the Launcher
|
||||
|
||||
![][9]
|
||||
|
||||
With Pop!_OS, you do not need a launcher like [Ulauncher][10] to quickly access the settings/apps.
|
||||
|
||||
This is because you already get a built-in launcher that works pretty well.
|
||||
|
||||
With Pop!_OS 22.04 LTS, the launcher has also received some upgrades where you can also access settings for desktop options, background, appearance, dock, and workspaces.
|
||||
|
||||
#### PipeWire for Audio
|
||||
|
||||
With Pop!_OS 22.04 LTS, the default for audio processing will use PipeWire instead of PulseAudio.
|
||||
|
||||
This should not pose a problem for hardware compatible with PulseAudio, and potentially opens up for better quality audio, and more customizations.
|
||||
|
||||
#### Linux Kernel
|
||||
|
||||
![][11]
|
||||
|
||||
It is a no-brainer that Pop!_OS regularly updates the Linux Kernel offered. However, you will find [Linux Kernel 5.16.19][1] with all the hardware improvements out-of-the-box.
|
||||
|
||||
#### Other Improvements
|
||||
|
||||
![][12]
|
||||
|
||||
There are some additional essential improvements that can be useful for a variety of users. Some of them include:
|
||||
|
||||
* Better Multi-Monitor support
|
||||
* Fixed layout on HiDPI displays
|
||||
* Improved performance
|
||||
* Pop!_OS Upgrade will only activate when you are checking or performing upgrades.
|
||||
* When updating Debian packages, you get the ability to resume it if interrupted.
|
||||
* Added support for laptop privacy screens.
|
||||
* RDP by default for remote desktop use.
|
||||
* New default profile icon.
|
||||
* Workspace improvements.
|
||||
* Icons are now SVG-based instead of PNG-based.
|
||||
|
||||
|
||||
|
||||
### Download Pop!_OS 22.04 LTS
|
||||
|
||||
If you are already running Pop!_OS, you should be easily able to upgrade it to Pop!_OS 22.04 in some time.
|
||||
|
||||
In either case, you can download the latest Nvidia/Intel/AMD ISO from the [official site][13].
|
||||

Shortwave 3.0 is Here With UI Upgrades, Private Stations, and More Improvements
|
||||
======
|
||||
Shortwave 3.0 comes packed with much-needed UI improvements, ability to add private stations, and more upgrades.
|
||||
|
||||
![shortave 3.0][1]
|
||||
|
||||
Shortwave is a popular internet radio player for GNOME. In total, more than 25,000 stations are available by default, all of which can be organized, searched, and cast to other devices (such as Chromecast).
|
||||
|
||||
Shortwave 3.0 brings these features to a whole new level, with some considerable changes. Let’s take a look at what’s new!
|
||||
|
||||
### Shortwave 3.0: What’s New?
|
||||
|
||||
Alongside the major inclusion of libadwaita, Shortwave 3.0 includes:
|
||||
|
||||
* Support for GNOME 42 Dark Mode
|
||||
* Ability to add private stations to the library
|
||||
* The ability to save station data to the disk
|
||||
* Improved sorting of search results
|
||||
|
||||
#### User Interface Changes
|
||||
|
||||
![Credits: Felix Häcker][2]
|
||||
|
||||
Over the past few months, many apps have been transitioning to [Libadwaita][3]. Thanks to its smooth visuals, integrated development workflow, and integration with GNOME, it has quickly become a must-have for all new apps.
|
||||
|
||||
The latest app to receive an upgrade to Libadwaita is Shortwave. As a result of this, it now features an adaptive user interface, potentially useful for Linux phones like the [PinePhone][4].
|
||||
|
||||
![][5]
|
||||
|
||||
Additionally, it now uses the more modern Adwaita design, which I really like.
|
||||
|
||||
With the UI improvements, it also supports the new GNOME 42 dark mode. Here’s what it looks like:
|
||||
|
||||
![shortwave 3.0][6]
|
||||
|
||||
#### Saving Station Data
|
||||
|
||||
![][7]
|
||||
|
||||
A useful feature addition includes the ability to save station data to the disk, instead of having to receive it from the server every time.
|
||||
|
||||
As a result, even if a station is removed from the server (*radio-browser.info*), it will remain in the app, with a message notifying the user of the change.
|
||||
|
||||
#### Add Private Stations
|
||||
|
||||
![][8]
|
||||
|
||||
Previously, you had to rely on the available stations in the library available with [*radio-browser.info*][9].
|
||||
|
||||
Now, you can add your private stations from your internal network or maybe an exclusive/paid stream available through an API key.
|
||||
|
||||
![][10]
|
||||
|
||||
#### Other Changes
|
||||
|
||||
In addition to the ones listed above, Shortwave 3.0 features a few other improvements:
|
||||
|
||||
* Display station bitrate information, which can also be used as a sorting option.
|
||||
* New button on the search page that allows to sort the search results.
|
||||
* Overhauled station dialog, with more clearly displayed information.
|
||||
* Update desktop notification on song change instead of generating a new separate notification for each song.
|
||||
* Shortwave can now be used normally, even if radio-browser.info is offline / unavailable.
|
||||
|
||||
### Wrapping Up
|
||||
|
||||
![][11]
|
||||
|
||||
Overall, Shortwave 3.0 is a fantastic release that combines improves the user experience and adds new functionalities.
|
||||
|
||||
If you want to install it, you can head to its [Flathub][12] page for instructions or simply type the below command into your terminal:
|
||||
|
||||
```
|
||||
flatpak install flathub de.haeckerfelix.Shortwave
|
||||
```
|
||||
|
||||
In case you haven’t set up Flatpak, you can refer to our [Flatpak guide][13] as well.

Why you should choose mindfulness over multitasking
|
||||
======
|
||||
If your brain is sputtering to a halt, you could be suffering from multitasking and decision fatigue.
|
||||
|
||||
![14 facts about OpenStack Newton][1]
|
||||
(Image by: Pixabay. Modified by Opensource.com. CC BY-SA 4.0)
|
||||
|
||||
You have your morning coffee in hand, you've just finished your daily scrum, and you sit down at your computer to start your day. Up pops a Slack message. You scan your emails, then bounce back to Slack. You look at your calendar to see when your next meeting is—much to your surprise, it's starting in 15 minutes. You get back to your desk and check your to-do list to see what tasks you can fit in before your next meeting, but one of your co-workers asks for your help to solve a problem. Before you know it, half of your day has disappeared.
|
||||
|
||||
Many of my days are spent like this, juggling multiple tasks. There are moments I find myself staring at my computer with my brain at a complete halt. If you, too, find yourself in this situation, it's probably a sign from your brain to take a break. You could be suffering from too much multitasking and decision fatigue.
|
||||
|
||||
On average, adults make about [35,000 decisions][2] every day! They can be simple decisions, such as what to eat or what to wear, or decisions that require more thought, such as where to go on your next vacation or which career to pursue. Every day you are faced with a plethora of choices to occupy your mind.
|
||||
|
||||
### Mindless multitasking
|
||||
|
||||
Not only are you faced with making thousands of decisions each day, but multitasking has also become the norm for busy and in-demand professionals. The problem is, multitasking hurts more than it helps. The more you divide your attention through multitasking, the more your productivity decreases.
|
||||
|
||||
In a study, self-described multitaskers were asked to switch back and forth between tasks at a pace that felt natural to them. A control group was asked to do one job at a time in sequence. The multitasking group performed far less effectively. Each time they switched tasks, there was a slowdown because it took time to time recall the details and the steps they'd done so far. This wound up making everything [take roughly 40% longer][3] and led to lower levels of accuracy overall. People who focused on one task at a time spent less time overall and finished all the tasks.
|
||||
|
||||
### Choose mindfulness
|
||||
|
||||
The mind functions optimally when it can focus on one activity at a time. Choosing mindfulness over multitasking will result in better feelings throughout your day and help you do better work.
|
||||
|
||||
"Mindfulness" can be defined as being conscious and aware. It really is about being present in the moment and focusing your attention on what's at hand. There are many advantages to mindfulness in the workplace. The trick is creating boundaries and habits that allow you to give each task your full attention.
|
||||
|
||||
Take a proactive approach and create a prioritized plan of the items that must get done each day. This will allow you to make real progress on a few things that are important instead of being reactive. Every item that goes on your to-do list should be discrete, clear, and actionable. Focus on three to five tasks per day.
|
||||
|
||||
### 3 ways to take a break during your workday
|
||||
|
||||
Don't forget to plan breaks throughout your day. The brain needs a few minutes of rest every hour to recuperate and to avoid burnout. Taking mini-breaks is good for your mental health and [leads to increased productivity][4].
|
||||
|
||||
Here are three easy ways to incorporate breaks into your day:
|
||||
|
||||
#### 1. Move your body
|
||||
|
||||
Take 10 minutes to get out of your chair and go for a short walk. If you're pressed for time, stand up and stretch for two minutes. Changing the position of your body and focusing on the present moment will help relieve the mental tension that has built up in your mind.
|
||||
|
||||
#### 2. Laugh more
|
||||
|
||||
Take a break to talk with your friends and colleagues at work. Laughter decreases stress hormones and triggers the release of endorphins, the body's natural feel-good chemicals. A little laughter break helps relax your mind and is also good for your soul.
|
||||
|
||||
#### 3. Breathe deeply
|
||||
|
||||
Reset your mind and body with a two-minute break to breathe deeply into your belly. Deep breathing calms your mind and body, improves oxygen flow, and gives you a natural energy boost.
|
||||
|
||||
1. Sit up tall with a straight spine, bring your awareness to your belly, and allow it to soften and relax.
|
||||
2. Begin with a slow, deep inhalation for a count of three, filling your belly, then rib cage, then upper chest with oxygen.
|
||||
3. Pause for a second, then exhale from your upper chest, rib cage then belly, drawing your belly in towards your spine at the end.
|
||||
4. Pause again, then repeat.
|
||||
|
||||
### Reset yourself
|
||||
|
||||
The next time you find yourself at a standstill or pressuring yourself to finish a task when your mind is not in the flow, try some of the tips above. It's better to take a short break and allow yourself to reset rather than trying to power through. Your body and brain will thank you.

How the C programming language has grown
|
||||
======
|
||||
Here's my interview with Brian Kernighan, co-author (with Dennis Ritchie) of The C Programming Language book, to discuss the C programming language and its 50-year history.
|
||||
|
||||
![The original C programming guide by two of the language authors, circa 1978][1]
|
||||
|
||||
The C programming language will turn fifty years old in 2022. Yet despite its long history, C remains one of the top "most-used" programming languages in many "popular programming languages" surveys. For example, check out the [TIOBE Index][2], which tracks the popularity of different programming languages. Many Linux applications are written in C, such as the GNOME desktop.
|
||||
|
||||
I interviewed [Brian Kernighan][3], co-author (with Dennis Ritchie) of *The C Programming Language* book, to learn more about the C programming language and its history.
|
||||
|
||||
**Where did the C programming language come from?**
|
||||
|
||||
C is an evolution of a sequence of languages intended for system programming—that is, writing programs like compilers, assemblers, editors, and ultimately operating systems. The Multics project at MIT, with Bell Labs as a partner, planned to write everything in a high-level language (a new idea at the time, roughly 1965). They were going to use IBM's PL/1, but it was very complicated, and the promised compilers didn't arrive in time.
|
||||
|
||||
After a brief flirtation with a subset called EPL (by Doug McIlroy of Bell Labs), Multics turned to BCPL, a much simpler and cleaner language designed and implemented by Martin Richards of Cambridge, who I think was visiting MIT at the time. When Ken Thompson started working on what became Unix, he created an even simpler language, based on BCPL, that he called B. He implemented it for the PDP-7 used for the first proto-Unix system in 1969.
|
||||
|
||||
BCPL and B were both "typeless" languages; that is, they had only one data type, integer. The DEC PDP-11, which arrived on the scene in about 1971 and was the computer for the first real Unix implementation, supported several data types, notably 8-bit bytes as well as 16-bit integers. For that, a language that also supported several data types was a better fit. That's the origin of C.
|
||||
|
||||
**How was C used within Bell Labs and the early versions of Unix?**
|
||||
|
||||
C was originally used only on Unix, though after a while, there were also C compilers for other machines and operating systems. Mostly it was used for system-programming applications, which covered quite a spectrum of interesting areas, along with a lot of systems for managing operations of AT&T's telephone network.
|
||||
|
||||
**What was the most interesting project written in C at Bell Labs?**
|
||||
|
||||
Arguably, the most interesting, memorable, and important C program was the Unix operating system itself. The first version of Unix in 1971 was in PDP-11 assembly language, but by the time of the fourth edition, around 1973, it was rewritten in C. That was truly crucial since it meant that the operating system (and all its supporting software) could be ported to a different kind of computer basically by recompiling everything. Not quite that simple in practice, but not far off.
|
||||
|
||||
**You co-authored The C Programming Language book with Dennis Ritchie. How did that book come about, and how did you and Dennis collaborate on the book?**
|
||||
|
||||
I had written a tutorial on Ken Thompson's B language to help people get started with it. I upgraded that to a tutorial on C when it became available. And after a while, I twisted Dennis's arm to write a C book with me. Basically, I wrote most of the tutorial material, except for the system call chapter, and Dennis had already written the reference manual, which was excellent. Then we worked back and forth to smooth out the tutorial parts; the reference manual stayed pretty much the same since it was so well done from the beginning. The book was formatted with the *troff* formatter, one of many tools on Unix, and I did most of the formatting work.
|
||||
|
||||
**When did C become a thing that other programmers outside of Bell Labs used for their work?**
|
||||
|
||||
I don't really remember well at this point, but I think C mostly followed along with Unix for the first half dozen years or so. With the development of compilers for other operating systems, it began to spread to other systems besides Unix. I don't recall when we realized that C and Unix were having a real effect, but it must have been in the mid to late 1970s.
|
||||
|
||||
**Why did C become such an influential programming language?**
|
||||
|
||||
The primary reason in the early days was its association with Unix, which spread rapidly. If you used Unix, you wrote in C. Later on, C spread to computers that might not necessarily run Unix, though many did because of the portable C compiler that Steve Johnson wrote. The workstation market, with companies like Sun Microsystems, MIPS (which became SGI), and others, was enabled by the combination of Unix and C. The IBM PC came somewhat later, about 1982, and C became one of the standard languages, under MS-DOS and then Windows. And today, most Internet of Things (IoT) devices will use C.
|
||||
|
||||
**C remains a popular programming language today, some 50 years after its creation. Why has C remained so popular?**
|
||||
|
||||
I think C hit a sweet spot with efficiency and expressiveness. In earlier times, efficiency really mattered since computers were slow and had limited memory compared to what we are used to today. C was very efficient, in the sense that it could be compiled into efficient machine code, and it was simple enough that it was easy to see how to compile it. At the same time, it was very expressive, easy to write, and compact. No other language has hit that kind of spot quite so well, at least in my humble but correct opinion.
|
||||
|
||||
**How has the C programming language grown or changed over the years?**
|
||||
|
||||
C has grown modestly, I guess, but I haven't paid much attention to the evolving C standards. There are enough changes that code written in the 1980s needs a bit of work before it will compile, but it's mostly related to being honest about types. Newer features like complex numbers are perhaps useful, but not to me, so I can't make an informed comment.
|
||||
|
||||
**What programming problems can be solved most easily in C?**
|
||||
|
||||
Well, it's a good language for anything, but today, with lots of memory and processing power, most programmers are well served by languages like Python that take care of memory management and other more high-level constructs. C remains a good choice for lower levels where squeezing cycles and bytes still matter.
|
||||
|
||||
**C has influenced other programming languages, including C++, Java, Go, and Rust. What are your thoughts on these other programming languages?**
|
||||
|
||||
Almost every language is in some ways a reaction to its predecessors. To over-simplify a fair amount, C++ adds mechanisms to control access to information, so it's better than C for really large programs. [Java][4] is a reaction to the perceived complexity of C++. Go is a reaction to the complexity of C++ and the restrictions of [Java][4]. [Rust][5] is an attempt to deal with memory management issues in C (and presumably C++) while coming close to C's efficiency.
|
||||
|
||||
They all have real positive attributes, but somehow no one is ever quite satisfied, so there will always be more languages that, in their turn, react to what has gone before. At the same time, the older languages, for the most part, will remain around because they do their job well, and there's an embedded base where they are perfectly fine, and it would be infeasible to reimplement in something newer.

How Linux rescues slow computers (and the planet)
|
||||
======
|
||||
Don't throw away your old computer. Skip the landfill and revive it with Linux.
|
||||
|

|
||||
|
||||
Mint and Kasen, two of my grandkids, asked me to help them build gaming computers. I am ecstatic that they asked. This gives me a great opportunity to help them learn about technology while being a part of their lives. Both of those things make me happy. There are many ways to approach the ecological impact of computers.
|
||||
|
||||
Wait! That's quite a non-sequitur—right? Not really, and this article is all about that.
|
||||
|
||||
### What happens to old computers?
|
||||
|
||||
What happens to old computers (and why) is a big part of this discussion. Start with the typical computer getting replaced after about five years of service. Why?
|
||||
|
||||
Online articles such as [this one][2] I found on CHRON, a publication aimed at small businesses suggest a three-to-five-year lifespan for computers. This is partly based on the alleged fact that computers slow down around that time in their life cycle. I find the pressure to get a newer, faster computer within that same time frame in this and other articles. Of course, much of that pressure comes from the computer and chip vendors who need to keep their income streams growing.
|
||||
|
||||
The United States Internal Revenue Service reinforces this five-year service life by specifying that time frame for full depreciation of computers.
|
||||
|
||||
Let's start with the myth of computer slowdowns. Computers don't slow down—ever. Computers always run at their designed clock speeds. Whether that is 2.8GHz or 4.5GHz, they will always run at that speed when busy. Of course, the clock speeds get intentionally reduced when the computer has little or nothing to do, saving power.
|
||||
|
||||
Computers don't slow down because they are old. Computers with Windows installed produce less legitimate work as they grow older because of the massive amount of malware, spyware, adware, and scareware they accumulate over time. Computer users have come to believe that this is normal, and they resign themselves to life with all of this junk dragging down the performance of their computers.

### Linux to the rescue
|
||||
|
||||
As a known computer geek among my friends and acquaintances, people sometimes gift me with their old computers. They no longer want them because they are slow, so they give them to me and ask me to wipe their hard drives before taking them to the electronics recycling center a few blocks from my house. I always suggest that their three-to-five-year-old computers are still good, but they seem intent on spending money rather than learning a new operating system.
|
||||
|
||||
I have several old computers gifted to me. One, in particular, a Dell Optiplex 755 with a 2.33 GHz Core 2 Duo processor and 8GB of RAM, is particularly interesting. Its BIOS is dated 2010, so it is around 12 years old. It is the oldest computer I have, and I keep it quite busy. I have had it for several years, and it never slows down because I use Linux on it—Fedora 35 right now.
|
||||
|
||||
If that is an exception, here are more. I built three computers for myself in 2012, ten years ago, and installed Fedora on all of them. They are all still running with no problems and as fast as they ever did.
|
||||
|
||||
There are no exceptions here, just normal operations for old computers on Linux.
|
||||
|
||||
Using Linux will at least double the usable lifetime of a computer and at no cost. This keeps those computers out of the landfill (at worst) and out of the recycling centers (at best) for an additional five-to-seven years or more.
|
||||
|
||||
So long as I can find replacement parts for these computers, I can keep them running and out of any disposal or recycling path. The problem with some computers is finding parts.
|
||||
|
||||
### Non-standard hardware
|
||||
|
||||
Let's talk about non-standard hardware and some of the computers that you can buy from some well-known companies. As I mentioned above, one of my old computers is a Dell. Dell is a respectable company that has been around for a long time. I will never purchase a Dell desktop or tower computer, although I will take them as donations or gifts. I can install Linux, get rid of Windows, and make these old computers useful again. I use them in my home lab as test computers, among other things.
|
||||
|
||||
However, Dell uses some non-standard parts that you can't easily replace. When you can find parts (like power supplies and motherboards), they are not cheap. The reason is that those vendors create systems with non-standard power supplies and motherboards that only fit within their own non-standard cases. This is a strategy used to keep revenues up. If you can't find these parts on the open market, you must go to the original manufacturer and pay inflated, if not exorbitant, prices.
|
||||
|
||||
As one example, the Dell Optiplex I have uses a motherboard, case, and power supply that do not meet generally accepted standards for physical compatibility. In other words, a Dell motherboard or power supply would not fit in a standard case that I can purchase at the local computer store or Amazon. Those parts would not fit in a gaming case that my grandkids would use. The holes for mounting the motherboard and power supply would not align. The power supply would not fit the space available in the standard case. The PCI card slots and back panel connectors on the motherboard would be in the wrong place for a standard case, and the power supply connectors would not match those on a standard motherboard.
|
||||
|
||||
Eventually, one or more of those non-standard parts will fail, and you won't be able to find a replacement at all, or at least not for a reasonable price. At that point, it makes sense to dispose of the old computer and purchase a new one.
|
||||
|
||||
### Standard builds
|
||||
|
||||
Let's explore what using standardized parts can do for building computers, their longevity, and how that applies to the gaming computers that I am helping my grandkids with.
|
||||
|
||||
Most motherboards are standardized. They have standard forms such as micro ATX, ATX, and extended ATX. All of these have mounting holes in standard locations. Many of the locations overlap, so holes for ATX motherboards align with many of the mounting holes used on extended ATX motherboards. This means that you can always use a case that has holes drilled for standard motherboard hole locations for any of those motherboards. These motherboards have standard power connectors, which means you can use them with any standard power supply.
|
||||
|
||||
I sent both of my grandkids a gaming computer case that has standardized mounting holes for the motherboards for their birthdays. These holes have standard threads so that they can use the brass standoffs that come with any motherboard in those motherboard mounting holes. The standoffs screw into the motherboard, and themselves have standard threaded holes that fit standard motherboard mounting screws.
|
||||
|
||||
The result of all this is that they can install any standard motherboard in any standard case using standard fasteners with any standard power supply.
|
||||
|
||||
Note that memory, processors, and add-in cards are all standardized, but they must be compatible with the motherboard. So memory for an old motherboard may no longer be available. You would need a new motherboard, memory, and processor in such a case. But the rest of the computer is still perfectly good.
|
||||
|
||||
As I have told Mint and Kasen, building (or purchasing) a computer with standard parts means never having to buy a new computer. The good case I gave them will never need replacement. Over time components may fail, but they only need to replace any defective parts. This continuous renewal of standardized parts will allow those computers to last a lifetime with minimal cost. If one component fails, just replace that one part and recycle the defective one.
|
||||
|
||||
This also significantly reduces the amount of material you need to recycle or otherwise add to the landfills.
|
||||
|
||||
### Recycling old computer parts
|
||||
|
||||
I am fortunate to live in a place that provides curbside recycling pickup. Although that curbside pickup does not include electronic devices, multiple locations around the area do take electronics for recycling, and I live close to one. I have taken many loads of old, unusable electronics to that recycling center, including my computers' defective parts. But never an entire computer.
|
||||
|
||||
I collect those defective parts in old cardboard boxes, sorted by type—electronics in one, metal in another, batteries in a third, and so on. This corresponds to the collection points at the recycling center. When a box or two get full, I take them for recycling.
|
||||
|
||||
### Some final thoughts
|
||||
|
||||
Even after a good deal of research for this article and my own edification in the past, it is very difficult to determine where the recycled computers and computer parts will go. The website for our recycling center indicates that the outcomes for each type of recycled material get based on its economic value. Computers have relatively large amounts of valuable metals and rare earth elements, so they get recycled.
|
||||
|
||||
The issue of whether such recycling gets performed in ways that are healthy for the people involved and the planet itself is another story. So far, I have been unable to determine where electronics destined for recycling go from here. I have decided that I need to do my part while working to ensure the rest of the recycling chain gets set up and functions appropriately.
|
||||
|
||||
The best option for the planet is to keep computers running as long as possible. Replacing only defective components as they go bad can keep a computer running for years longer than the currently accepted lifespan and significantly reduces the amount of electronic waste that we dump in landfills or that needs recycling.
|
||||
|
||||
And, of course, use Linux so your computers won't slow down.

I Ditched Ubuntu for Manjaro: Here’s What I Think After a Week
|
||||
======
|
||||
|
||||
Primarily, I rely on Ubuntu-based distributions like Pop!_OS, Zorin OS, Linux Mint, or Ubuntu itself for work.
|
||||
|
||||
They get out of the way when I work on something, along with seamless software updates. Not to forget, they get along well with my Intel-Nvidia-powered system.
|
||||
|
||||
Everything (can be subjective) works out of the box.
|
||||
|
||||
However, I recently decided to switch to Arch Linux on bare metal (because I mostly used it on virtual machines).
|
||||
|
||||
And then, I ended up using **Manjaro Linux** (an Arch-based distro).
|
||||
|
||||
### Here’s Why I Picked Manjaro Linux
|
||||
|
||||
To my surprise, I couldn’t even get past the “_nouveau DRM: core notifier timeout_” error, let alone proceed with the installation when using a **live USB for Arch Linux**. Yes, I’m aware of the [guided installer with Arch Linux][1], but the connected displays just kept on flickering, highlighting this error, no matter what.
|
||||
|
||||
The best solution to this problem was not to get an NVIDIA card with my recent upgrade.
|
||||
|
||||
_Too bad, I prefer Nvidia GPUs…_
|
||||
|
||||
AMD’s RX 6600 XT is similarly priced to RTX 3060 Ti; it did not make sense to get that card for 1440p.
|
||||
|
||||
So, yes, RTX 3060 Ti can be the problem in my case.
|
||||
|
||||
While I found some methods to troubleshoot the issue, I was too lazy. I just wanted to see if I could experience Arch Linux without putting in a great effort.
|
||||
|
||||
**So, here’s what I did:**
|
||||
|
||||
The next-best option would be to try any of the [best Arch-based distros][2] tailored to make things easy, right?
|
||||
|
||||
And that’s where **Manjaro Linux** comes in.
|
||||
|
||||
Manjaro Linux is a popular Arch-based distro, and I’ve noticed regular improvements to it with every update (while using it on a VM).
|
||||
|
||||
Furthermore, I like Manjaro’s default theme accent color for my desktop experience.
|
||||
|
||||
So, I decided to give it a try…
|
||||
|
||||
### Manjaro Linux: Rough Start
|
||||
|
||||
![][3]
|
||||
|
||||
I did not have any issues installing Manjaro with proprietary Nvidia drivers. However, a recent point update, i.e., **Manjaro Linux 21.2.6,** messed up the system.
|
||||
|
||||
I couldn’t access the login screen and the [TTY][4] (all I could see was the motherboard’s manufacturer logo)
|
||||
|
||||
So, I had to re-install Manjaro Linux using the latest ISO, and so far, so good (touch wood).
|
||||
|
||||
And during my usage of Manjaro Linux, I noticed a few things that make up for its good and bad points.
|
||||
|
||||
Here, I highlight some of my experiences. These insights should help you explore more about it if you haven’t tried it yet.
|
||||
|
||||
#### 1\. Easy Installation
|
||||
|
||||
The primary highlight of an Arch-based distro is to make things easy to set up. And I had no issues whatsoever.
|
||||
|
||||
It was a breeze installing Manjaro Linux on my secondary drive. The bootloader was correctly configured to display the Manjaro-themed boot menu that lets me select Windows/Manjaro Linux for dual-boot.
|
||||
|
||||
#### 2\. Manjaro Hello
|
||||
|
||||
![][5]
|
||||
|
||||
The welcome experience makes up for a significant part of a user experience when trying something new. And Manjaro Linux does not disappoint in this regard.
|
||||
|
||||
You get all the essential information if you pay close attention to the information available via the welcome screen.
|
||||
|
||||
The GNOME Layouts Manager lets you pick a suitable layout to get yourself comfortable.
|
||||
|
||||
![][6]
|
||||
|
||||
However, I couldn’t get the “**Window Tiling**” functionality working when I tried to enable it here:
|
||||
|
||||
![][7]
|
||||
|
||||
#### 3\. Package Manager is Fast and Versatile
|
||||
|
||||
![][8]
|
||||
|
||||
Considering that GNOME is my favorite desktop environment, I have had terrible experiences with the software center (or even with distro-specific stores like Pop!_Shop).
|
||||
|
||||
While they get the work done, sometimes they do not respond or aren’t responsive enough as I expect them to be.
|
||||
|
||||
With Manjaro Linux, I found [Pamac][9] installed as the package manager. It seems to be one of the [best ways to install and remove software on Manjaro Linux][10].
|
||||
|
||||
In my experience, it was blazing fast with installations and removing packages. You also get prompts for conflicts in packages or if something needs to be replaced/removed. The package manager gives plenty of information about the optional/required dependencies when you install something.
|
||||
|
||||
Overall, it was a pretty good experience without any slowdowns. To sweeten the experience, the package manager lets you quickly enable the support for **Flatpaks/Snaps/AUR** by tweaking the preferences of pamac.
|
||||
|
||||
![][11]
|
||||
|
||||
So, you do not have to use the terminal or different software stores. Everything will be available under a single roof, which is a big time saver.
|
||||
|
||||
#### 4\. Trying out the ZSH Shell
|
||||
|
||||
![][12]
|
||||
|
||||
I am used to the bash shell on Ubuntu-based distros. However, Manjaro Linux features the ZSH shell by default. I believe ZSH is better than bash, but I’ll take a deep dive into the comparison with a separate article soon.
|
||||
|
||||
In other words, I get to try something different out of the box. To my excitement, the terminal prompt and the theme for the shell (or the terminal) that follows the Manjaro branding accent colors look pretty impressive!
|
||||
|
||||
![][12]
|
||||
|
||||
Hence, I do not need to [customize the look of the terminal here][13].
|
||||
|
||||
To explore more, you might want to check some of our resources on [what ZSH is][14] and [how to install it][15].
|
||||
|
||||
#### 5\. Lack of Official Software Support
|
||||
|
||||
![][16]
|
||||
|
||||
I hope this improves soon. But, as of now, many software/utilities offer direct support for Ubuntu and Fedora only.
|
||||
|
||||
You can find official DEB/RPM packages for various tools, but neither will work directly with Manjaro Linux.
|
||||
|
||||
You will have to rely on the packages available in Arch Linux repositories or [AUR][17].
|
||||
|
||||
Fortunately, there are good chances to find the software in AUR or their repositories maintained by the community or distro developers. Just like I was able to get [Insync][18] (_affiliate link_) to work on Manjaro Linux with file manage integration extensions available.
|
||||
|
||||
However, without official support for the platform, you may/may not miss out on some features or quick updates.
|
||||
|
||||
Of course, if you rely on [Flatpak][19] or Snap packages, it should not be an issue for you. Furthermore, if you are new to Linux, you can refer to our [Flatpak guide][20] for more information.
|
||||
|
||||
#### 6\. No Fractional Scaling
|
||||
|
||||
I have a dual-monitor setup with 1080p + 1440p resolutions. So, fractional scaling helps, but I can manage without it.
|
||||
|
||||
To enable fractional scaling on Manjaro, you will have to install x11-scaling enabled packages for Mutter and GNOME control center. The packages include:
|
||||
|
||||
* **mutter-x11-scaling**
|
||||
* **gnome-control-center-x11-scaling**
|
||||
|
||||
|
||||
|
||||
This will replace your existing mutter and gnome control center packages. So, you will lose the default theme/accent settings for your desktop.
|
||||
|
||||
You may have to utilize GNOME Tweaks to get things right. But, it can turn out to be an annoying experience.
|
||||
|
||||
### Final Thoughts
|
||||
|
||||
Overall, I enjoy the desktop experience with Manjaro Linux. If another system update doesn’t break the experience, I think I will continue with Manjaro Linux as my new daily driver.
|
||||
|
||||
_What do you think are the strong/weak points for Manjaro Linux? Did I miss something as part of my new experience? Do you have any suggestions as an experienced Arch Linux user?_

10 Reasons to Run Linux in Virtual Machines
|
||||
======
|
||||
You can run any operating system as a virtual machine to test things out or for a particular use case.
|
||||
|
||||
When it comes to Linux, it is usually a better performer as a virtual machine when compared to other operating systems. Even if you hesitate to install Linux on bare metal, you can try setting up a virtual machine that could run as you would expect on a physical machine.
|
||||
|
||||
Of course, we don’t rule out the possibility of running Linux distros in VM even when using Linux as your host OS.
|
||||
|
||||
Moreover, you get numerous benefits when trying to run Linux on virtual machines. Here, I shall mention all about that.
|
||||
|
||||
### Things to Keep in Mind Before Running Linux as a Virtual Machine
|
||||
|
||||
It is worth noting that running Linux on a virtual machine may not be a daunting task, but there are a few pointers that you should keep in mind.
|
||||
|
||||
Some of them include:
|
||||
|
||||
* The virtual machine performance will depend on your host system. If you do not have enough system resources to allocate, the virtual machine experience will not be pleasant.
|
||||
* Certain features only work well with bare metal (hardware acceleration, graphics drivers, etc.)
|
||||
* You should not expect intensive disk I/O tasks to work well, like testing games.
|
||||
* The user experience with Linux virtual machines varies with the program you use. For instance, you can try VMware, VirtualBox, GNOME Boxes, and Hyper-V.
|
||||
|
||||
In addition to all these tips, you should also make a list of your requirements before choosing a virtual machine program to run Linux.
|
||||
|
||||
### Here Are 10 Benefits of Running Linux on Virtual Machines
|
||||
|
||||
While there are perks to using a Linux VM, you should consider the current opportunities available on your host OS. For instance, you may want to [install Linux using WSL on Windows][1] if you do not require a GUI desktop.
|
||||
|
||||
Once you are sure that you need a VM, here’s why you should proceed with it:
|
||||
|
||||
#### 1. Easy Setup
|
||||
|
||||
![easy setup linux vm][2]
|
||||
|
||||
Compared to the traditional installation process on bare metal, setting up a virtual machine is often easier.
|
||||
|
||||
For Ubuntu-based distros, programs like VMware offer an **Easy Install** option where you have to type in the required fields for username and password; the rest will proceed without needing additional inputs. You do not need to select a partition, bootloader, or advanced configurations.
|
||||
|
||||
In some cases, you can also use prebuilt images offered by Linux distributions for a specific virtual program, where you need to open it to access the system. Think of it as a portable VM image ready to launch wherever you need it.
|
||||
|
||||
For example, you can check out how you can use [VirtualBox to install Arch Linux][3].
|
||||
|
||||
You may still need to configure things when installing other distros, but there are options where you need minimal effort.
|
||||
|
||||
#### 2. Does Not Affect the Host OS
|
||||
|
||||
![isolated linux vm][4]
|
||||
|
||||
With a virtual machine, you get the freedom to do anything you want, and it is because you get an isolated system.
|
||||
|
||||
Usually, if you do not know what you’re doing with a Linux system, you could easily end up with a messed-up configuration.
|
||||
|
||||
So, if you set up a VM, you can quickly try whatever you want without worrying about affecting the host OS. In other words, your system will not be impacted by any changes to the VM because it’s entirely isolated.
|
||||
|
||||
Hence, a VM is the best way to test any of your ambitious or destructive changes that you may want to perform on bare metal.
|
||||
|
||||
#### 3. Resource Sharing
|
||||
|
||||
![sharing resources linux vm][5]
|
||||
|
||||
If you have ample free system resources, you can utilize the rest using a Virtual Machine for any other tasks. For instance, if you want a private browsing experience without leaving any traces on your host, a VM can help.
|
||||
|
||||
It can be a far-fetched example, but it is just one of the ideas. In that way, you get to use the resources fully without much hassle.
|
||||
|
||||
Also, as opposed to a dual-boot scenario, where you need to [install Linux alongside Windows][6] on separate disks or [install Windows after Linux][7], you need dedicated resources locked on to your tasks.
|
||||
|
||||
However, with a VM, you can always use Linux without locking up your resources, rather than temporarily sharing them to get your tasks done, which can be more convenient.
|
||||
|
||||
#### 4. Multi-Tasking
|
||||
|
||||
![multitasking linux vm][8]
|
||||
|
||||
With the help of resource-sharing, you can easily multi-task.
|
||||
|
||||
For instance, you need to switch back and forth between a dual-boot setup to access Windows and Linux.
|
||||
|
||||
But, with a virtual machine, you can almost eliminate the need for [dual-booting Linux][9] and multi-task with two operating systems seamlessly.
|
||||
|
||||
Of course, you need to ensure that you have the required amount of system resources and external hardware (like dual monitors) to effectively use it. Nevertheless, the potential to multi-task increases with a Linux VM in place.
|
||||
|
||||
#### 5. Facilitates Software Testing
|
||||
|
||||
With virtualization, you get the freedom to test software on Linux distros by instantly creating various situations.
|
||||
|
||||
For instance, you can test different software versions simultaneously on multiple Linux VMs. There can be more use-cases, such as testing a software development build, early build of a Linux distro, etc.
|
||||
|
||||
#### 6. Great for Development
|
||||
|
||||
![development linux vm][10]
|
||||
|
||||
When you want to learn to code or just get involved in developing something, you want an environment free from any conflicts and errors.
|
||||
|
||||
So, a Linux VM is the perfect place to install new packages from scratch without worrying about conflicts with existing ones. For instance, you can [install and set up Flutter][11] to test things on Ubuntu.
|
||||
|
||||
If you mess up the system, you can quickly delete the VM and spin up a new one to learn from your mistakes.
|
||||
|
||||
You get a perfect isolated environment for development work and testing with a Linux VM.
|
||||
|
||||
#### 7. Learning or Research
|
||||
|
||||
Linux is something to explore. While you could use it for basic computing tasks, there’s so much more that you can do with it.
|
||||
|
||||
You can learn how to customize the user interface, try some [popular desktop environments][12], install [various essential apps][13], and take control of your system without worrying about it.
|
||||
|
||||
If anything goes wrong, you create a new Linux VM. Of course, it is not just for general-purpose usage, but aspiring system administrators can also take this opportunity to test what they learn.
|
||||
|
||||
#### 8. Easy to Clone or Migrate
|
||||
|
||||
Virtual machines, in general, are easy to clone and migrate. With a Linux VM, as long as the virtual program is supported on another system or host OS, you can easily migrate it without any special requirements.
|
||||
|
||||
If you need to clone an existing virtual machine for any reason, that is pretty easy too, and it should take a couple of clicks to get it done.
|
||||
|
||||
#### 9. Try Variety of Distros
|
||||
|
||||
![distros linux vm][14]
|
||||
|
||||
Of course, with hundreds of Linux distros available, you can try all kinds of distros by creating a Linux virtual machine.
|
||||
|
||||
You may consider this a part of learning/research, but I believe trying out different distros is a massive task if you want to test things out before installing them on your system.
|
||||
|
||||
#### 10. Debugging
|
||||
|
||||
Whether it is for fun or serious research, debugging is relatively more straightforward in an isolated environment provided by the Linux VM.
|
||||
|
||||
You get the freedom to try various troubleshooting methods without thinking about the outcome. Also, you do not need root access to your host OS (if it’s Linux) to access the system configuration/files in the VM.
|
||||
|
||||
### Wrapping Up
|
||||
|
||||
If you are not an experienced user or depend on a different host OS, you can benefit from installing Linux using a virtual machine.
|
||||
|
||||
A Linux VM should be beneficial for development, learning, experimenting, or any other special use cases.
|
||||
|
||||

How I grew my product management career with open source
|
||||
======
|
||||
Gaining experience in open source helped me create a successful career path in product management.
|
||||
|
||||
![How to make release notes count][1]
|
||||
(Image by: Opensource.com)
|
||||
|
||||
I'm a curious person, and I like to explore many fields in the technology industry, from visual design, programming, and product management. I am also drawn to open source ideas. So I'm excited to share with you how I, as a product manager (PM), have used open source to build my career. I believe my experiences can help others who are interested in product management.
|
||||
|
||||
### What is open source software?
|
||||
|
||||
In simple terms, open source software is software with source code that anyone can inspect, modify, enhance, and share. [Opensource.com][2] has documented a detailed and [comprehensive article][3] to help you understand what open source is.
|
||||
|
||||
My discovery of open source started in the early phase of my career as a visual designer. I was curious to know what it meant and how to be a part of it and that led me to reach out to a few experienced open source contributors and advocates. Though I didn't contribute at the time, I acquired knowledge of the community which helped me when I made the decision to start contributing.
|
||||
|
||||
### How to break into product management
|
||||
|
||||
It might seem that breaking into product management is difficult, that you must put your boxing gloves on, come out fighting and force your way in. And yet, I've heard from other product managers that it was actually easier to break into compared to writing or debugging blocks of code, or pushing pixels to generate complex wireframes for product design.
|
||||
|
||||
Our journeys and approaches are different, so it's safe to say that the road to becoming a product manager can often be long and unpredictable. With the increasing level of competition in the job market, getting a role as an entry-level product manager can be difficult. Recruiters often require 2 to 3 years of experience to join a product team. You might ask, "How am I expected to get the experience?"
|
||||
|
||||
Here's a quick look at the four strategies for directing your career toward product management:
|
||||
|
||||
1. Internal transition at a large organization that might require your manager to advocate for you as a good fit to transition within the company. You must have proof that you have transferable skills. This is generally considered the quickest route to product management experience.
|
||||
2. Junior PM roles at large organizations. It's common to go through an organization to get an internship, or to join an associate product management program that employs a junior PM.
|
||||
3. You can also try to get into product management by joining a startup.
|
||||
4. You can start a side project of your own to break into product management.
|
||||
|
||||
Without hands-on experience, it's difficult to become a product manager. As open source product manager [David Ryan][4] stated, "Few people are taking advantage of what is possibly the most under-utilized path to practical product management experience."
|
||||
|
||||
What is this path?
|
||||
|
||||
### Open source is the answer
|
||||
|
||||
An open source project needs more than just code to be successful. This ranges from a strategy for the project, user research, and linking the strategy to daily work. These are all activities that a product manager should be actively involved in. But how much of the product management discipline is the responsibility of a first-time product manager?
|
||||
|
||||
[Susana Videira Lopes][5] stated in one of her articles that the "essence of getting an entry-level product role is to introduce you to the product management discipline in a way that builds up your confidence, while at the same time delivering value for the organization as early as possible."
|
||||
|
||||
How can an entry-level product manager get involved with an open source project, and deliver value?
|
||||
|
||||
**Simple answer: Ask Questions**
|
||||
|
||||
Here are some questions you can ask:
|
||||
|
||||
* What problem or opportunity is being explored?
|
||||
* How is the solution being framed to tackle this problem?
|
||||
* What metrics are used to determine whether the project is successful?
|
||||
* Who are the people this solution serves?
|
||||
* How are they being informed about it?
|
||||
* How does the solution fit with both the immediate and wider ecosystem?
|
||||
* Where is the documentation being maintained on the project?
|
||||
* Do project maintainers understand accessibility requirements? Are they being met?
|
||||
|
||||
You've acquired skills as a product manager. Use them to help you express these thoughtful questions, and invite the team to consider them. The team can select the ones that resonate for the developers and the community, and prioritize what's most important.
|
||||
|
||||
These questions help you build user personas, a customer journey map, lean canvas, and more. This kind of experience goes a long way towards developing career potential.
|
||||
|
||||
### My experience at OpenUnited
|
||||
|
||||
[OpenUnited][6] is a platform that connects digital talent and work in a unique way. We work with contributors to help them prove specific skills by working on high quality open source products. Once their work is verified, these talented contributors are eligible to work for companies on paid tasks.
|
||||
|
||||
OpenUnited is an open source platform that onboards contributors of all kinds—product managers, developers, designers, business analysts, and others. It helps them improve their skills and provides them with a long term source of high-quality paying work.
|
||||
|
||||
Farbod Saraf, a senior product manager at Miro, onboarded me on a platform he created with a partner. I joined the project and learned about contributing to OpenUnited. I also learned about other projects that could help me grow in my product management career, and made my first contribution. It was a good experience because I got to start working quickly on bits of the product, to improve the experience of other users on the platform. My mentor Farbod made it easier by making himself available to provide any needed help while I contributed to the project.
|
||||
|
||||
Everything you contribute to an open source project becomes a powerful public record of your development as a product manager. I strongly recommend the OpenUnited platform to anyone who wants to break into product management with open source.
|
||||
|
||||
### How do you find open source projects?
|
||||
|
||||
Many people believe that contributing to open source is best left to developers because they find it difficult to search for and get open source projects they can comfortably contribute to.
|
||||
|
||||
As a first-time product manager, there are several ways to find open source projects to contribute to. Here's a list of some:
|
||||
|
||||
* Speak up in product manager communities such as Mind The Product and Product School.
|
||||
* Go to local meetups and open source conferences like Open Source Community Africa Festival to connect with open source project creators and maintainers.
|
||||
* Engage with product managers working at larger open source companies such as GitLab or Mozilla. They may be able to refer you to open source projects where your skills and contribution could be beneficial.
|
||||
* Investigate open source advocates and DevRel teams at open source companies to get recommendations of open projects an entry-level product manager can contribute to.
|
||||
* Look to open source companies on AngelList or popular open source products on Product Hunt. These are great places to consider in your search for open products to contribute to.
|
||||
|
||||
### What next?
|
||||
|
||||
[Ruth Ikegah][7], a great source of inspiration for me, wrote an [article for beginners in open source][8]. In her article, she gave some tips to consider as you embark on contributing to open source.
|
||||
|
||||
Before joining and contributing, do some research on the project, community, or organization, and ask questions. When you finally decide to join the community, try to be active by introducing yourself and stating areas where you can help the project.
|
||||
|
||||
Of course, open source isn't just a stepping stone for your career. It's a platform in itself, and it needs great product managers. Get involved, contribute to the community, and help it help you hone your skills.

6 tips for securing your WordPress website
|
||||
======
|
||||
Even beginners can—and should—take these steps to protect their
|
||||
WordPress sites against cyberattacks.
|
||||
![A lock on the side of a building][1]
|
||||
|
||||
Already powering over 30% of the internet, WordPress is the fastest-growing content management system (CMS) in the world—and it's not hard to see why. With tons of customization available through coding and plugins, top-notch SEO, and a supreme reputation for blogging, WordPress has certainly earned its popularity.
|
||||
|
||||
However, with popularity comes other, less appealing attention. WordPress is a common target for intruders, malware, and cyberattacks—in fact, WordPress accounted for around [90% of hacked CMS platforms][2] in 2019.
|
||||
|
||||
Whether you're a first-time WordPress user or an experienced developer, there are important steps you can take to protect your WordPress website. The following six key tips will get you started.
|
||||
|
||||
### 1\. Choose reliable hosting
|
||||
|
||||
Hosting is the unseen foundation of all websites—without it, you can't publish your site online. But hosting does much more than simply host your site. It's also responsible for site speed, performance, and security.
|
||||
|
||||
The first thing to do is to check if a host includes SSL security in its plans.
|
||||
|
||||
SSL is an essential security feature for all websites, whether you're running a small blog or a large online store. You'll need a more [advanced SSL certificate][3] if you're accepting payments, but for most sites, the basic free SSL should be fine.
|
||||
|
||||
Other security features to look out for include:
|
||||
|
||||
* Frequent, automatic offsite backups
|
||||
* Malware and antivirus scanning and removal
|
||||
* Distributed denial of service (DDoS) protection
|
||||
* Real-time network monitoring
|
||||
* Advanced firewall protection
|
||||
|
||||
|
||||
|
||||
In addition to these digital security features, it's worth thinking about your hosting provider's _physical_ security measures as well. These include limiting access to data centers with security guards, CCTV, and two-factor or biometric authentication.
|
||||
|
||||
### 2\. Use security plugins
|
||||
|
||||
One of the best—and easiest—ways of protecting your website's security is to install a security plugin, such as [Sucuri][4], which is an open source, GPLv2 licensed project. Security plugins are vitally important because they automate security, which means you can focus on running your site rather than committing all your time to fighting off online threats.
|
||||
|
||||
These plugins detect and block malicious attacks and alert you about any issues that require your attention. In short, they constantly work in the background to protect your site, meaning you don't have to stay awake 24/7 to fight off hackers, bugs, and other digital nasties.
|
||||
|
||||
A good security plugin will provide all the essential security features you need for free, but some advanced features require a paid subscription. For example, you'll need to pay if you want to unlock [Sucuri's website firewall][5]. Enabling a web application firewall (WAF) blocks common threats and adds an extra layer of security to your site, so it's a good idea to look for this feature when choosing a security plugin.
|
||||
|
||||
### 3\. Choose trustworthy plugins and themes
|
||||
|
||||
The joy of WordPress is that it is open source, so anyone and everyone can pitch in with themes and plugins that they've developed. This can also pose problems when it comes to picking a high-quality theme or plugin.
|
||||
|
||||
It serves to be cautious when picking a free theme or plugin, as some are poorly designed—or worse, may hide malicious code.
|
||||
|
||||
To avoid this, always source free themes and plugins from reputable sources, such as the WordPress library. Always read reviews and research the developer to see if they've built any other programs.
|
||||
|
||||
Outdated or poorly designed themes and plugins can leave "backdoors" open for attackers or bugs to get into your site, which is why it pays to be careful in your choices. However, you should also be wary of nulled or cracked themes. These are premium themes that have been compromised by hackers and are for sale illegally. You might buy a nulled theme believing that it's all above-board—only to have your site damaged by hidden malicious code.
|
||||
|
||||
To avoid nulled themes, don't get drawn in by discounted prices, and always stick to reputable stores, such as the official [WordPress directory][6]. If you're looking elsewhere, stick to large and trusted stores, such as [Themify][7], a theme and plugin store that has been running since 2010. Themify ensures all its WordPress themes pass the [Google Mobile-Friendly][8] test and are open source under the [GNU General Public License][9].
|
||||
|
||||
### 4\. Run regular updates
|
||||
|
||||
It's a fundamental WordPress rule: _always keep your site up to date._ However, it's a rule not everyone sticks to—in fact, only [43% of WordPress sites][10] are running the latest version.
|
||||
|
||||
The problem is that when your site becomes outdated, it becomes susceptible to glitches, bugs, intrusions, and crashes because it falls behind on security and performance fixes. Outdated sites can't fix bugs the same way as updated sites can, and attackers can tell which sites are outdated. This means they can search for the most vulnerable sites and attack accordingly.
|
||||
|
||||
This is why you should always run your site on the latest version of WordPress. And in order to keep your security at its strongest, you must update your plugins and themes as well as your core WordPress software.
|
||||
|
||||
If you choose a managed WordPress hosting plan, you might find that your provider will check and run updates for you—be clear whether your host offers software _and_ plugin updates. If not, you can install an open source plugin manager, such as the GPLv2-licensed [Easy Updates Manager plugin][11], as an alternative.
|
||||
|
||||
### 5\. Strengthen your logins
|
||||
|
||||
Aside from creating a secure WordPress website through carefully choosing your theme and installing security plugins, you also need to safeguard against unauthorized access through logins.
|
||||
|
||||
#### Password protection
|
||||
|
||||
The first and simplest way to strengthen your login security is to change your password—especially if you're using an [easily guessed phrase][12] such as "123456" or "qwerty."
|
||||
|
||||
Instead, try to use a long passphrase rather than a password, as they are harder to crack. The best way is to use a series of unrelated words strung together that you find easy to remember.
|
||||
|
||||
Here are some other tips:
|
||||
|
||||
* Never reuse passwords
|
||||
* Don't include obvious words such as family members' names or your favorite football team
|
||||
* Never share your login details with anyone
|
||||
* Include capitals and numbers to add complexity to your passphrase
|
||||
* Don't write down or store your login details anywhere
|
||||
* Use a [password manager][13]
|
||||
|
||||
|
||||
|
||||
#### Change your login URL
|
||||
|
||||
It's a good idea to change your default login web address from the standard format: yourdomain.com/wp-admin. This is because hackers know this is the default URL, so you risk brute-force attacks by not changing it.
|
||||
|
||||
To avoid this, change the URL to something different. Use an open source plugin such as the GPLv2-licensed [WPS Hide Login][14] for safe, quick, and easy customization.
|
||||
|
||||
#### Apply two-factor authentication
|
||||
|
||||
For extra protection against unauthorized logins and brute-force attacks, you should add two-factor authentication. This means that even if someone _does_ get access to your login details, they'll need a code that's sent directly to your phone to gain access to your WordPress site's admin.
|
||||
|
||||
Adding two-factor authentication is pretty easy. Simply install yet another plugin—this time, search the WordPress Plugin Directory for "two-factor authentication," and select the plugin you want. One option is [Two Factor][15], a popular GPLv2 licensed project that has over 10,000 active installations.
|
||||
|
||||
#### Limit login attempts
|
||||
|
||||
WordPress tries to be helpful by letting you guess your login details as many times as you like. However, this is also helpful to hackers trying to gain unauthorized access to your WordPress site to release malicious code.
|
||||
|
||||
To combat brute-force attacks, install a plugin that limits login attempts and set how many guesses you want to allow.
|
||||
|
||||
### 6\. Disable file editing
|
||||
|
||||
This isn't such a beginner-friendly step, so don't attempt it unless you're a confident coder—and always back up your site first!
|
||||
|
||||
That said, disabling file editing _is_ an important measure if you're really serious about protecting your WordPress website. If you don't hide your files, it means anyone can edit your theme and plugin code straight from the admin area—which is dangerous if an intruder gets in.
|
||||
|
||||
To deny unauthorized access, go to your **wp-config.php** file and enter:
|
||||
|
||||
|
||||
```
|
||||
<Files wp-config.php>
|
||||
order allow,deny
|
||||
deny from all
|
||||
</Files>
|
||||
```
|
||||
|
||||
Or, to remove the theme and plugin editing options from your WordPress admin area completely, edit your **wp-config.php** file by adding:
|
||||
|
||||
|
||||
```
|
||||
`define( 'DISALLOW_FILE_EDIT', true );`
|
||||
```
|
||||
|
||||
Once you've saved and reloaded the file, the plugin and theme editors will disappear from your menus within the WordPress admin area, stopping anyone from editing your theme or plugin code—including you**.** Should you need to restore access to your theme and plugin code, just delete the code you added to your **wp-config.php** file when you disabled editing.
|
||||
|
||||
Whether you block unauthorized access or totally disable file editing, it's important to take action to protect your site's code. Otherwise, it's easy for unwelcome visitors to edit your files and add new code. This means an attacker could use the editor to gather data from your WordPress site or even use your site to launch attacks on others.
|
||||
|
||||
For an easier way of hiding your files, you can use a security plugin that will do it for you, such as Sucuri.
|
||||
|
||||
### WordPress security recap
|
||||
|
||||
WordPress is an excellent open source platform that should be enjoyed by beginners and developers alike without the fear of becoming a victim of an attack. Sadly, these threats aren't going anywhere anytime soon, so it's vital to stay on top of your site's security.
|
||||
|
||||
Using the measures outlined above, you can create a stronger, more secure level of protection for your WordPress site and ensure a much more enjoyable experience for yourself.
|
||||
|
||||
Staying secure is an ongoing commitment rather than a one-time checklist, so be sure to revisit these steps regularly and stay alert when building and using your CMS.

Troubleshoot WiFi problems with Go and a Raspberry Pi
|
||||
======
|
||||
Build a WiFi scanner for fun.
|
||||
![Selfcare, drinking tea on the porch][1]
|
||||
|
||||
Last summer, my wife and I sold everything we owned and moved with our two dogs to Hawaii. It's been everything we thought it would be: beautiful sun, warm sand, cool surf—you name it. We've also run into some things we didn't expect: WiFi problems.
|
||||
|
||||
Now, that's not a Hawaii problem. It's limited to the apartment we are renting. We are living in a single-room studio apartment attached to our landlord's apartment. Part of the rent includes free internet! YAY! However, said internet is provided by the WiFi router in the landlord's apartment. BOO!
|
||||
|
||||
In all honesty, it works OK. Ish. OK, it doesn't work well, and I'm not sure why. The router is literally on the other side of the wall, but our signal is spotty, and we have some trouble staying connected. Back home, our WiFi router's signal crossed through many walls and some floors. Certainly, it covered an area larger than the 600 sq. foot apartment we live in!
|
||||
|
||||
What does a good techie do in such a situation? Why, investigate, of course!
|
||||
|
||||
Luckily the "everything we own" that we sold before moving here did not include our Raspberry Pi Zero W. So small! So portable! Of course, I took it to Hawaii with me. My bright idea was to use the Pi and its built-in WiFi adapter, write a little program in Go to measure the WiFi signal received from the router, and display that output. I'm going to make it super simple, quick, and dirty and worry later about making it better. I just want to know what's up with the WiFi, dang it!
|
||||
|
||||
Hunting around on Google for a minute turns up a relatively useful Go package for working with WiFi, [mdlayher/wifi][2]. Sounds promising!
|
||||
|
||||
### Getting information about the WiFi interfaces
|
||||
|
||||
My plan is to query the WiFi interface statistics and return the signal strength, so I need to find the interfaces on the device. Luckily the mdlayher/wifi package has a method to query them, so I can do that by creating a file named `main.go`:
|
||||
|
||||
|
||||
```
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"github.com/mdlayher/wifi"
|
||||
)
|
||||
|
||||
func main() {
|
||||
|
||||
c, err := wifi.New()
|
||||
defer c.Close()
|
||||
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
interfaces, err := c.Interfaces()
|
||||
|
||||
for _, x := range interfaces {
|
||||
fmt.Printf("%+v\n", x)
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
So, what's going on here? After importing it, the mdlayher/wifi module can be used in the main function to create a new Client (type `*Client`). The new client (named `c`) can then get a list of the interfaces on the system with `c.Interfaces()`. Then it can loop over the slice of Interface pointers and print information about them.
|
||||
|
||||
By adding "+" to `%+v`, it prints the names of the fields in the `*Interface` struct, too, which helps me identify what I'm seeing without having to refer back to documentation.
|
||||
|
||||
Running the code above provides a list of the WiFi interfaces on my machine:
|
||||
|
||||
|
||||
```
|
||||
&{Index:0 Name: HardwareAddr:5c:5f:67:f3:0a:a7 PHY:0 Device:3 Type:P2P device Frequency:0}
|
||||
&{Index:3 Name:wlp2s0 HardwareAddr:5c:5f:67:f3:0a:a7 PHY:0 Device:1 Type:station Frequency:2412}
|
||||
```
|
||||
|
||||
Note that the MAC address, `HardwareAddr`, is the same for both lines, meaning this is the same physical hardware. This is confirmed by `PHY: 0`. The Go [wifi module's docs][3] note that `PHY` is the physical device to which the interface belongs.
|
||||
|
||||
The first interface has no name and is `TYPE:P2P`. The second, named `wpl2s0` is `TYPE:Station`. The wifi module documentation lists the [different types of interfaces][4] and describes what they are. According to the docs, the "P2P" type indicates "an interface is a device within a peer-to-peer client network." I believe, and please correct me in the comments if I'm wrong, that this interface is for [WiFi Direct][5], a standard for allowing two WiFi devices to connect without an intermediate access point.
|
||||
|
||||
The "Station" type indicates "an interface is part of a managed basic service set (BSS) of client devices with a controlling access point." This is the standard function for a wireless device that most people are used to—as a client connected to an access point. This is the interface that matters for testing the quality of the WiFi.
|
||||
|
||||
### Getting the Station information from the interface
|
||||
|
||||
Using this information, I can update the loop over the interfaces to retrieve the information I'm looking for:
|
||||
|
||||
|
||||
```
|
||||
for _, x := range interfaces {
|
||||
if x.Type == wifi.InterfaceTypeStation {
|
||||
// c.StationInfo(x) returns a slice of all
|
||||
// the staton information about the interface
|
||||
info, err := c.StationInfo(x)
|
||||
if err != nil {
|
||||
fmt.Printf("Station err: %s\n", err)
|
||||
}
|
||||
for _, x := range info {
|
||||
fmt.Printf("%+v\n", x)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
First, it checks that `x.Type` (the Interface type) is `wifi.InterfaceTypeStation`—a Station interface (that's the only type that matters for this exercise). This is an unfortunate naming collision—the interface "type" is not a "type" in the Golang sense. In fact, what I'm working on here is a Go `type` named `InterfaceType` to represent the type of interface. Whew, that took me a minute to figure out!
|
||||
|
||||
So, assuming the interface is of the _correct_ type, the station information can be retrieved with `c.StationInfo(x)` using the client `StationInfo()` method to get the info about the interface, `x`.
|
||||
|
||||
This returns a slice of `*StationInfo` pointers. I'm not sure quite why there's a slice. Perhaps the interface can have multiple StationInfo responses? In any case, I can loop over the slice and use the same `+%v` trick to print the keys and values for the StationInfo struct.
|
||||
|
||||
Running the above returns:
|
||||
|
||||
|
||||
```
|
||||
`&{HardwareAddr:70:5a:9e:71:2e:d4 Connected:17m10s Inactive:1.579s ReceivedBytes:2458563 TransmittedBytes:1295562 ReceivedPackets:6355 TransmittedPackets:6135 ReceiveBitrate:2000000 TransmitBitrate:43300000 Signal:-79 TransmitRetries:2306 TransmitFailed:4 BeaconLoss:2}`
|
||||
```
|
||||
|
||||
The thing I'm interested in is the "Signal" and possibly "TransmitFailed" and "BeaconLoss." The signal is reported in units of dBm (or decibel-milliwatts).
|
||||
|
||||
#### A quick aside: How to read WiFi dBm
|
||||
|
||||
According to [MetaGeek][6]:
|
||||
|
||||
* –30 is the best possible signal strength—it's neither realistic nor necessary
|
||||
* –67 is very good; it's for apps that need reliable packet delivery, like streaming media
|
||||
* –70 is fair, the minimum reliable packet delivery, fine for email and web
|
||||
* –80 is poor, absolute basic connectivity, unreliable packet delivery
|
||||
* –90 is unusable, approaching the "noise floor"
|
||||
|
||||
|
||||
|
||||
_Note that dBm is logarithmic scale: -60 is 1,000x lower than -30_
|
||||
|
||||
### Making this a real "scanner"
|
||||
|
||||
So, looking at my signal from above: –79. YIKES, not good. But that single result is not especially helpful. That's just a point-in-time reference and only valid for the particular physical space where the WiFi network adapter was at that instant. What would be more useful would be a continuous reading, making it possible to see how the signal changes as the Raspberry Pi moves around. The main function can be tweaked again to accomplish this:
|
||||
|
||||
|
||||
```
|
||||
var i *wifi.Interface
|
||||
|
||||
for _, x := range interfaces {
|
||||
if x.Type == wifi.InterfaceTypeStation {
|
||||
// Loop through the interfaces, and assign the station
|
||||
// to var x
|
||||
// We could hardcode the station by name, or index,
|
||||
// or hardwareaddr, but this is more portable, if less efficient
|
||||
i = x
|
||||
break
|
||||
}
|
||||
}
|
||||
|
||||
for {
|
||||
// c.StationInfo(x) returns a slice of all
|
||||
// the staton information about the interface
|
||||
info, err := c.StationInfo(i)
|
||||
if err != nil {
|
||||
fmt.Printf("Station err: %s\n", err)
|
||||
}
|
||||
|
||||
for _, x := range info {
|
||||
fmt.Printf("Signal: %d\n", x.Signal)
|
||||
}
|
||||
|
||||
time.Sleep(time.Second)
|
||||
}
|
||||
```
|
||||
|
||||
First, I name a variable `i` of type `*wifi.Interface`. Since it's outside the loop, I can use it to store the interface information. Any variable created inside the loop is inaccessible outside the scope of that loop.
|
||||
|
||||
Then, I can break the loop into two. The first loop ranges over the interfaces returned by `c.Interfaces()`, and if that interface is a Station type, it stores that in the `i` variable created earlier and breaks out of the loop.
|
||||
|
||||
The second loop is an infinite loop, so it'll just run over and over until I hit **Ctrl**+**C** to end the program. This loop takes that interface information and retrieves the station information, as before, and prints out the signal information. Then it sleeps for one second and runs again, printing the signal information over and over until I quit.
|
||||
|
||||
So, running that:
|
||||
|
||||
|
||||
```
|
||||
[chris@marvin wifi-monitor]$ go run main.go
|
||||
Signal: -81
|
||||
Signal: -81
|
||||
Signal: -79
|
||||
Signal: -81
|
||||
```
|
||||
|
||||
Oof. Not good.
|
||||
|
||||
### Mapping the apartment
|
||||
|
||||
This information is good to know, at least. With an attached screen or E Ink display and a battery (or a looooong extension cable), I can walk the Pi around the apartment and map out where the dead spots are.
|
||||
|
||||
Spoiler alert: With the landlord's access point in the apartment next door, the big dead spot for me is a cone shape emanating from the refrigerator in the studio apartment's kitchen area… the refrigerator that shares a wall with the landlord's apartment!
|
||||
|
||||
I think in Dungeons and Dragons lingo, this is a "Cone of Silence." Or at least a "Cone of Poor Internet."
|
||||
|
||||
Anyway, this code can be compiled directly on the Raspberry Pi with `go build -o wifi_scanner`, and the resulting binary, `wifi_scanner`, can be shared with any other ARM devices (of the same version). Alternatively, it can be compiled on a regular system with the right libraries for ARM devices.
|
||||
|
||||
Happy Pi scanning! May your WiFi router not be behind your refrigerator! You can find the code used for this project in [my GitHub repo][7].

Getting Started With Markdown [Beginner’s Guide]
|
||||
======
|
||||
|
||||
In my work, I often have to write code, write the documentation that goes with that code, create Web pages, and work on text restoration projects, and have written several formal papers while I was in school. I can include class notes here, too; I needed to write them for nearly every class.
|
||||
|
||||
I use Markdown for nearly all of my writing and it is a major time-saver for me.
|
||||
|
||||
In this article, I am going to share my experience with Markdown. You’ll be learning the following:
|
||||
|
||||
* What is Markdown?
|
||||
* How does it work?
|
||||
* Markdown basic syntax and how to use them
|
||||
|
||||
|
||||
|
||||
### What is Markdown?
|
||||
|
||||
If you are new to Markdown, it is a text-to-HTML conversion tool for web writers. Markdown files follow a specific syntax that is easy to read and just as easy to write. They are plain text files so they can be created using any text editor on any computer. These files can then be turned into Web pages – and Web pages are built using a markup called HTML.
|
||||
|
||||
Markdown then, is just a way to create Web pages without the need (or even know how) to write HTML code. Actually, Markdown is an great way to format plain text even if you don’t have to convert to HTML. Someone once described Markdown to me this way:
|
||||
|
||||
> “It isn’t _what you see is what you get_, but _what you see is what you mean_”.
|
||||
|
||||
Markdown, however, is more than an easy formatting scheme, it is also a software tool that converts the plain text formatting to HTML.
|
||||
|
||||
This is why the syntax is important. If you want a title on your Web page, Markdown will create one based on the character(s) you use in front of your title. A sampling of some of Markdown’s syntax is shown this screenshot:
|
||||
|
||||
![Markdown to HTML conversion][1]
|
||||
|
||||
### So how do I make this plain text to HTML conversion?
|
||||
|
||||
John Gruber’s Markdown is a Perl script that is run on the command line. Basically, it reads the Markdown text that you create and builds a Web page from it.
|
||||
|
||||
I will avoid the command line here since there are [many outstanding Markdown editors][2] that can do this conversion for you. Not only that, many of these editors will let you write your text and show you what the Web page will look like (called _rendering_) at the same time.
|
||||
|
||||
Markdown editors are generally set up to show two frames. The left frame is where you write your text and the right frame shows you what the formatted text will look like in HTML:
|
||||
|
||||
![Most Markdown editors have two panes to write and preview the text][3]
|
||||
|
||||
When you are finished with your text and are happy with it, simply save the Markdown file. This way, you’ll always have it in case you need to edit or rewrite later. Once the file is saved, you can have the editor export the markdown file to HTML.
|
||||
|
||||
The editor will create the Web page, using your Markdown as a reference. Your Markdown file will not be changed during an export – you will still have it – along with a separate, newly created HTML (Web page) file that you can put on a Web server.
|
||||
|
||||
**Note**: Many Markdown editors can also export your Markdown files to other formats, such as `.doc`, `.docx`, and `.pdf`. You can learn about those advanced setups, and extra software you might need, later on.
|
||||
|
||||
### Basic Markdown Syntax
|
||||
|
||||
To get the new Markdown user up to speed quickly, I will limit this to cover the syntax I use most often. These, I believe will be the most helpful – you can be productive now while you learn more about what Markdown can do for you later on.
|
||||
|
||||
#### Write Headings
|
||||
|
||||
I normally use `#` characters to denote headings. There are six levels:
|
||||
|
||||
```
|
||||
# Level 1 Heading
|
||||
## Level 2 Heading
|
||||
### Level 3 Heading
|
||||
#### Level 4 Heading
|
||||
##### Level 5 Heading
|
||||
###### Level 6 Heading
|
||||
```
|
||||
|
||||
There is another heading style that uses lines underneath the text. I rarely use this type of heading since I am limited to only two. A double line, which is made with the `=` character, makes a `H1` heading. A single line, made with the `-` character, makes a `H2` heading:
|
||||
|
||||
```
|
||||
Level 1 Heading
|
||||
===============
|
||||
|
||||
Level 2 Heading
|
||||
---------------
|
||||
```
|
||||
|
||||
![][4]
|
||||
|
||||
#### Paragraphs
|
||||
|
||||
Paragraphs are separated by a blank line (make sure that there is a blank line between paragraphs). Do not indent the first line at all. Indenting with a `<Tab>` or `<spaces>` has a different purpose in Markdown.
|
||||
|
||||
A paragraph is a block of text and should not be indented with spaces or tabs. It can have one line or many lines. To end a paragraph and start a new one, the `<Enter>` key is hit twice; paragraphs are separated by a blank line.
|
||||
|
||||
![][5]
|
||||
|
||||
#### Line Breaks
|
||||
|
||||
Remember that with paragraphs, a blank line has to separate them and this is done by pressing twice on the `<Enter>` key. Markdown is strict about it.
|
||||
|
||||
Markdown does not support “hard-wrapped” or “fixed-line-length” paragraphs. That is, hitting the `<Enter>` key once will not force text to a new line. It may appear so in the editing window, but the HTML won’t show it.
|
||||
|
||||
Yet, there will be times when you may need to break up paragraphs with some way to break up a line. Markdown does have a way to do this but it may seem a little strange at first: **a line break is made by ending a line with two or more spaces and then hitting the `<Enter>` key once.**
|
||||
|
||||
![][6]
|
||||
|
||||
Here is a working example of a short verse. Each line has two spaces at the end. The last line, since it’s the end of the verse, doesn’t have the extra spaces. Since it’s the end of the verse (paragraph), I hit the `<Enter>` key twice:
|
||||
|
||||
Baa, baa black sheep,
|
||||
Have you any wool?.
|
||||
Yes, sir. Yes, sir.
|
||||
Three bags full.
|
||||
|
||||
Adding two spaces at the end of a line, to create a line break, can take some getting used to.
|
||||
|
||||
![][7]
|
||||
|
||||
#### Horizontal Rules
|
||||
|
||||
Horizontal rules are great for splitting up text into sections.
|
||||
|
||||
Use three or more dashes `-`, underscores `_`, or asterisks `*` for horizontal rules, like so:
|
||||
|
||||
```
|
||||
`---`
|
||||
|
||||
`***`
|
||||
|
||||
`___`
|
||||
```
|
||||
|
||||
You can even put spaces between the characters:
|
||||
|
||||
```
|
||||
`- - -`
|
||||
```
|
||||
|
||||
I do not use horizontal rules very often in articles or papers, but they come in handy for me in journal entries, system logs, and class notes.
|
||||
|
||||
![][8]
|
||||
|
||||
#### Emphasis on text with bold and italics
|
||||
|
||||
When you want a word or phrase to stand out and be noticed, you can either make it bold or italicized. Italics and bold text can be made on one of two ways. The first is by surrounding the text with asterisks `*`, while the second is to use underscores `_`.
|
||||
|
||||
To italicize a word or phrase, surround the text with one underscore or asterisk. To make a word or phrase bold, surround it with two underscores or asterisks:
|
||||
|
||||
```
|
||||
This is *italics* made with asterisks.
|
||||
|
||||
This is _italics_ made with underscores.
|
||||
|
||||
This is **bold** made with asterisks.
|
||||
|
||||
This is __bold__ made with underscores.
|
||||
```
|
||||
|
||||
Remember to use the same character. An asterisk on one side of a word or phrase, and an underscore on the side, will not work. The same character has to be on both sides of the word or phrase.
|
||||
|
||||
![][9]
|
||||
|
||||
#### Block quotes
|
||||
|
||||
Block quotes are used for direct quotes. If you were writing a blog entry and you wanted to repeat something that Benjamin Franklin said, you could use a block quote.
|
||||
|
||||
A right angle bracket is used to specify a block quote:
|
||||
|
||||
```
|
||||
> This is a block quote.
|
||||
|
||||
>> Use two right angle brackets if you want a block quote that is further indented.
|
||||
```
|
||||
|
||||
![][10]
|
||||
|
||||
#### Adding links in Markdown
|
||||
|
||||
Links are just plain cool. There are three ways to create links on basic Markdown, but I will only cover two here: Regular links and automatic links.
|
||||
|
||||
The third type of link, called reference links, are supported in basic Markdown and more advanced flavors. I want to get to started quickly. You can look up reference links when you are ready for that.
|
||||
|
||||
Regular links let you link to various websites. The name of the site, or a phrase you want to use, is placed in square brackets `[]`. The actual link is inside parentheses `()`.
|
||||
|
||||
```
|
||||
Visit [It's FOSS](https://itsfoss.com) today!
|
||||
```
|
||||
|
||||
Automatic links are made with angle brackets `<>` surrounding the link. The link is an actual address (either a Web or email address). The link is spelled out and, when it is converted to HTML, the spelled out link becomes a working link.
|
||||
|
||||
```
|
||||
<http://automatic-link-to-url.com/>
|
||||
|
||||
<[email protected]>
|
||||
```
|
||||
|
||||
This is useful for when you want to spell out the address in your text:
|
||||
|
||||
![][11]
|
||||
|
||||
#### Adding images in Markdown
|
||||
|
||||
Links to images are almost identical to links to Web sites. The small difference between site links and images, is that image links begin with a bang (exclamation point) `!`
|
||||
|
||||
The name of the image, or a descriptive phrase of the image, is placed in square brackets `[]`. The actual link is inside parentheses `()`.
|
||||
|
||||
You can embed images like so:
|
||||
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
Here’s an example image link. It is a sample link, with no image, but it is a decent sample of how an actual link might look like:
|
||||
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
![][12]
|
||||
|
||||
#### Lists
|
||||
|
||||
Lists are made for many reasons. They can be used as ‘things to do’ items, topic elements in an outline, parts lists in an assembly project, and so on. There are two main types of lists: unordered and ordered.
|
||||
|
||||
Unordered lists are not numbered; these are the ‘bullet items’ we see in many documents. Ordered lists are numbered.
|
||||
|
||||
To create an ordered (numbered) list, just begin each line with a number, like so:
|
||||
|
||||
```
|
||||
1. Item one.
|
||||
2. Item two.
|
||||
3. Item three.
|
||||
```
|
||||
|
||||
Unordered lists are not numbered, but use either an asterisk `*`, a plus sign `+`, or a minus sign `-` at the beginning of each item on the list. I prefer to use either an asterisk or minus sign, but you get to choose:
|
||||
|
||||
```
|
||||
* Item one.
|
||||
+ Item two.
|
||||
- Item three.
|
||||
```
|
||||
|
||||
Sub-items can be added to both ordered and unordered lists by indenting, like so:
|
||||
|
||||
```
|
||||
1. Item 1
|
||||
1. Sub-item 1
|
||||
2. Sub-item 2
|
||||
2. Item 2
|
||||
3. Item 3
|
||||
```
|
||||
|
||||
![][13]
|
||||
|
||||
### Markdown syntax cheat sheet
|
||||
|
||||
For your reference, here is a short listing of Markdown syntax that has been covered in this small introduction.
|
||||
|
||||
If you decide to adopt it as a writing tool, you’ll find that Markdown has the means to simplify writing even more.
|
||||
|
||||

|
||||
|
||||
### Conclusion
|
||||
|
||||
Markdown can do more than what I have described here. A huge percentage of my writing can be accomplished with the Markdown syntax I have covered here – and these are the items I use most often even in more complex projects.
|
||||
|
||||
If all of this seems too simple, it really is that easy. Markdown was built to simply the writing task, but you don’t have to take my word for it. Try it out! There is no need to install a Markdown editor; you can do this online. There are several [good online Markdown editors][16]. Here are three that I prefer:
|
||||
|
||||
John Gruber’s [Dingus][17], [Editor.md][18], and [Dillinger][19]. Editor.md and Dillinger will let you see your Markdown rendered as HTML in real time. Dingus doesn’t preview in real time, but there is a Markdown syntax cheat sheet on the page for reference.
|
||||
|
||||
![][20]
|
||||
|
||||
Try out some of the examples in this article on either of these online editors. Try out some of your own ideas, too. This will let you get used to Markdown before possibly committing to learn more about it.

Give Your Linux Mint and Xubuntu a Visual Uplift Using Twister UI
|
||||
======
|
||||
TWISTER UI IS THE EASIEST WAY TO GIVE YOUR LINUX MINT AND XUBUNTU A
|
||||
VISUAL UPLIFT USING PRE-LOADED THEMES. HERE’S HOW.
|
||||
[Twister UI][1] is an add-on to your existing Linux Mint and Xubuntu installation. The Pi Labs created this UI, who made the [Twister OS][2] for Raspberry Pi and related hardware.
|
||||
|
||||
### Twister UI
|
||||
|
||||
The Twister UI is a collection of packages for [Linux Mint][3], and Xubuntu brings several popular OS-specific themes and configurations out of the box. You can apply them with just a click of a button. You do not need to download separate icons, themes or cursors.
|
||||
|
||||
The latest release gives out-of-box desktop theme, icons, sound, and other settings changes for the below OS types.
|
||||
|
||||
* Native Twister OS Theme
|
||||
* Windows 98, Windows 7, Windows XP
|
||||
* Windows 11, Windows 10
|
||||
* iTwister and iTwister Sur (for macOS)
|
||||
|
||||
|
||||
|
||||
#### How does it work?
|
||||
|
||||
The team prepared automated scripts that download all popular OS-specific themes, sounds, etc., from GitHub. Then the script modifies them, download additional packages from the Ubuntu repository and installs this add-on as a whole. The installer takes care of installing everything by itself, and all you need to do is wait.
|
||||
|
||||
Before we explain to you how to install it, let’s look at some of the screenshots and features of this OS mod. These screenshots are from the Linux Mint Xfce edition with this OS mod applied.
|
||||
|
||||
#### How it looks (screenshots)

|
||||
|
||||
#### Contents of the Twister UI Package
|
||||
|
||||
The package brings its own settings app called ThemeTwister. You can use this to switch themes quickly. You can change as many times you want between them. Nothing breaks.
|
||||
|
||||
The project also installs some good open-source packages by default. It installs Lutris, Steam gaming platforms to help you quickly play games. It also installs Discord, Wine emulator for the users.
|
||||
|
||||
As you can see, the team carefully thought of which packages to install, considering the user base of this add-on.
|
||||
|
||||
### How to Install
|
||||
|
||||
If you plan to install this, I recommend using this package in Linux Mint Xfce edition and Xubuntu. Do not try to install it in other Linux distributions _(I tried before reading the documentation, I messed up my Fedora install, so don’t try it in other distributions)_.
|
||||
|
||||
The requirement is a Linux Mint Xfce or Xubuntu installation (wither 32-bit 64-bit). It also requires around 5 GB of disk space.
|
||||
|
||||
First, download the package from the below link, which contains the Torrent link. It is not an ISO file. It consists of three files, one of which is the actual script.
|
||||
|
||||
[Download Twister UI][1]
|
||||
|
||||
Once downloaded, open the downloaded folder, and you should see a file with extension .run (as below).
|
||||
|
||||
![Give the execute permission to the run file][7]
|
||||
|
||||
Change the permission of the file to make it executable. Then run it via the terminal.
|
||||
|
||||
The script requires an admin password, so provide that once asked. Before you start the installation, make sure that you have a stable internet connection to download additional packages on the fly.
|
||||
|
||||
![Starting the installation script][8]
|
||||
|
||||
The download and installation take some time. Depending on your internet speed, it might take around 15 to 20 minutes.
|
||||
|
||||

|
||||
|
||||
You should know that the installer will replace the default Plymouth and .
|
||||
|
||||
Once installation completes, the script should prompt you to reboot.
|
||||
|
||||
After reboot, log in to your Linux Mint Xfce or Xubuntu system.
|
||||
|
||||
### How to Change Themes
|
||||
|
||||
If you are using the Linux Mint Xfce edition, you need to make the following additional changes for the best results before changing the theme:
|
||||
|
||||
* Open Application Menu > Settings > Desktop, under the Icons tab, uncheck the Use custom font size.
|
||||
* Open Application Menu > Settings > Window Manager tweaks, under the Compositor tab, uncheck Show shadows under dock windows.
|
||||
|
||||
|
||||
|
||||
You should now see a “ThemeTwister” icon on the desktop and open the application. This application gives you options to change themes, as shown below.
|
||||
|
||||
![Changing theme using ThemeTwister tool][10]
|
||||
|
||||
Select a theme and click on the respective button. Each time you change or apply a piece, the script asks you to log off. So make sure you close all your programs before changing the theme.
|
||||
|
||||
### How to Uninstall
|
||||
|
||||
If you are done and want to uninstall, then open a terminal and run the following shell script.
|
||||
|
||||
```
|
||||
|
||||
sh /usr/share/ThemeSwitcher/uninstall.sh
|
||||
|
||||
```
|
||||
|
||||
The above script only uninstalls Twister UI components and doesn’t uninstall Steam, Lutris etc. So if you want to uninstall, use the Software manager to uninstall them.
|
||||
|
||||
It would be best if you did a reboot after uninstallation.
|
||||
|
||||
### Review and Performance
|
||||
|
||||
As per the Pi Labs documentation, the customizations should not consume much additional memory. And it is true.
|
||||
|
||||
The customization is not impacting much on the desktop performance. When I ran one or two of the customization in Linux Mint Xfce edition in idle mode, it consumed around 740 MB of memory with CPU around 2% to 3%. This itself is impressive. The only cost of using this is the additional disk space.
|
||||
|
||||
![Resource Usage in Linux Mint with Twister UI][11]
|
||||
|
||||
The theme switcher is excellent and flawlessly changes the theme without surprises or errors.
|
||||
|
||||
In general, the entire process is error-free and went well as per its design.
|
||||
|
||||
### Closing Notes
|
||||
|
||||
After downloading individual themes icons and changing settings, you can manually configure your Linux distribution to look like Windows or macOS. That takes a lot of time and is sometimes difficult for new users. With that in mind, I think this new approach is a time saver and very easy for everyone. You can get all the required mods with just a click of a button.
|
||||
|
||||
There will always be an argument about why a Linux need to look like Windows or macOS. But older folks may not be familiar with computers much and remember the Windows colours and icons. They can adapt Linux using this simple modification without any hassles.
|
||||
|
||||
Overall, it’s an excellent project from the Pi Labs and helps many users worldwide.

||||

A guide to JVM parameters for Java developers
|
||||
======
|
||||
By understanding and using JVM and JVM parameters, both developers and end users can diagnose failures and improve the performance of a Java application.

When you write source code, you're writing code for humans to read. Computers can't execute source code until the code is compiled into *machine language*, a generic term referring to any number of languages required by a specific machine. Normally, if you compile code on Linux, it runs on Linux, and if you compile code on Windows, it runs on Windows, and so on. However, Java is different. It doesn't target an actual machine. It targets something called the Java Virtual Machine (JVM), and so it can run on any machine.
|
||||
|
||||
Java source code gets compiled into bytecode which is run by a JVM installed on a computer. The JVM is an execution engine, but it's not one you usually interact with directly. It runs quietly, processing Java bytecode. Most people don't need to think or even know about the JVM, but it can be useful to understand how the JVM works so you can debug and optimize Java code. For example:
|
||||
|
||||
* In the production environment, you might find a deployed application needs a performance boost.
|
||||
* If something goes wrong in an application you've written, both the developer and end-user have options to debug the problem.
|
||||
* Should you want to know the details of the Java Development Kit (JDK) being used to develop or run a Java application, you can get those details by querying the JVM.

### What's the difference between a JVM, JDK, and JRE?
|
||||
|
||||
Java has a lot of J-acronyms, including JVM, JDK, and JRE.
|
||||
|
||||
* A Java Developer Kit (JDK) is accessed by programmers who need development libraries to use in their code.
|
||||
* The Java Runtime Environment (JRE) is employed by people who want to run a Java application.
|
||||
* The Java Virtual Machine (JVM) is the component that runs Java bytecode.

The JDK contains both a JRE and a JVM, but some Java distributions provide an alternate download containing a JRE (including a JVM).

|

Java is open source, so different companies build and distribute JDKs. You can install more than one on your system, which can be helpful when you're working on or using different Java projects, some of which might use an old JDK.
|
||||
|
||||
To list the JDKs on your Linux system, you can use the alternatives command:
|
||||
|
||||
```
|
||||
$ alternatives --config java
|
||||
There are 2 programs that provide java.Selection Command-----------------------------------------------*+ 1 java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.13.0.8-2.fc35.x86_64/bin/java)2 java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-2.fc35.x86_64/jre/bin/java)
|
||||
Enter to keep the current selection[+], or type selection number:
|
||||
```
|
||||
|
||||
To switch between available JDKs, run the command again:
|
||||
|
||||
```
|
||||
$ sudo alternatives --config java
|
||||
```
|
||||
|
||||
Another option is to use [SDKMan][4], which helps you download, update, and manage the JDKs on your system.
|
||||
|
||||
### What is JVM tuning?
|
||||
|
||||
Tuning a JVM is the process of adjusting JVM parameters to improve the performance of the Java application. It also helps to diagnose application failure.
|
||||
|
||||
In general, it's important to consider these points before tuning:
|
||||
|
||||
* Cost : Sometimes, improving the hardware running your code can improve an application's performance. That might seem like a "cheat" but consider how much time you're willing to spend tuning the JVM parameters. Sometimes, an application requires more memory to perform as desired, and no amount of software hacking will change that.
|
||||
* Desired Outcome: Stability is more important than performance in the long run. If your tuning affects the stability, it's probably better to wisely choose your tuning parameters.
|
||||
* Underlying issues : Sometimes, the issue could be an underlying issue with the host operating system. Before tuning the JVM, ensure that the JVM's platform is working as expected.
|
||||
* Memory leaks: If you find yourself using Garbage Collection (GC) tuning parameters, there are likely memory leaks that need to get fixed in the application code.
|
||||

||||

|
||||
|
||||
### Types of JVM Parameters
|
||||
|
||||
JVM parameters are grouped under three categories: Standard options, Non-standard, and Advanced.
|
||||
|
||||
#### Standard options
|
||||
|
||||
All JVM implementations support standard options. Run the 'java' command in a terminal to see a list of standard options.
|
||||
|
||||
```
|
||||
$ java
|
||||
Usage: java [options] <mainclass> [args...]
|
||||
(to execute a class)
|
||||
or java [options] -jar <jarfile> [args...]
|
||||
(to execute a jar file)
|
||||
where options include:
|
||||
-cp <class search path of directories and zip/jar files>
|
||||
-classpath <class search path of directories and zip/jar files>
|
||||
--class-path <class search path of directories and zip/jar files>
|
||||
A : separated list of directories, JAR archives,
|
||||
and ZIP archives to search for class files.
|
||||
--enable-preview
|
||||
allow classes to depend on preview features of this release
|
||||
To specify an argument for a long option, you can use --<name>=<value> or--<name> <value>.
|
||||
```
|
||||
|
||||
These are all standard options included with any JVM, and you can safely use them as you use any [command-line option][5]. For example, to validate command options for configuration, and create a VM and load a main class without executing the main class, use:
|
||||
|
||||
```
|
||||
$ java --dry-run <classfile>
|
||||
```
|
||||
|
||||
#### Non-standard options
|
||||
|
||||
Non-standard options start with `-X`. These are for general purpose use and are specific to a particular implementation of JVM. To list these options:
|
||||
|
||||
```
|
||||
$ java -X-Xbatch disable background compilation-Xbootclasspath/a:<directories and zip/jar files separated by :>
|
||||
append to end of bootstrap class path-Xinternalversion
|
||||
displays more detailed JVM version information than the-version option-Xloggc:<file> log GC status to a file with time stamps[...]
|
||||
```
|
||||
|
||||
These extra options are subject to change without notice and are not supported by all JVM implementations.
|
||||
|
||||
A JVM built by Microsoft may have different options than one built by Red Hat, and so on.
|
||||
|
||||
To get detailed JVM version information, use the following option:
|
||||
|
||||
```
|
||||
$ java -Xinternalversion --version
|
||||
OpenJDK 64-Bit Server VM (11.0.13+8) for linux-amd64 JRE (11.0.13+8), built on Nov 8 2021 00:00:00 by "mockbuild" with gcc 11.2.1 20210728 (Red Hat 11.2.1-1)
|
||||
```
|
||||
|
||||
To get the property setting use:
|
||||
|
||||
```
|
||||
$ java -XshowSettings:properties --version
|
||||
```
|
||||
|
||||
#### Advanced options
|
||||
|
||||
These options are not for casual use and are used for tuning the specific areas of the Hotspot VM. These options are subject to change, and there is no guarantee that all JVM implementations will support it.
|
||||
|
||||
These options start with -XX. To list these options, use the following command:
|
||||
|
||||
```
|
||||
$ java -XX:+UnlockDiagnosticVMOptions -XX:+PrintFlagsFinal -version
|
||||
```
|
||||
|
||||
For example, to trace the class loading then use the below command:
|
||||
|
||||
```
|
||||
$ java -XX:+TraceClassLoading Hello
|
||||
```
|
||||
|
||||
The Hello.java has:
|
||||
|
||||
```
|
||||
$ cat Hello. javapublic class Hello {
|
||||
public static void main(String[] args) {
|
||||
System.out.println("Inside Hello World!");
|
||||
}}
|
||||
```
|
||||
|
||||
Another common problem you might face is OOM (Out Of Memory) errors, which can happen without much debug information. To solve such a problem, you might use the debug option -XX:+HeapDumpOnOutOfMemoryError, which creates a .hprof file with debug information.
|
||||
|
||||
```
|
||||
$ cat TestClass. java
|
||||
import java.util.ArrayList;
|
||||
import java.util.List;
|
||||
|
||||
public class TestClass {
|
||||
public static void main(String[] args) {
|
||||
List<Object> list = new ArrayList<Object>();
|
||||
for (int i = 0; i < 1000; i++) {
|
||||
list.add(new char[1000000]);
|
||||
}
|
||||
}
|
||||
}
|
||||
$ Javac TestClass.java
|
||||
$ java -XX:+HeapDumpOnOutOfMemoryError -Xms10m -Xmx1g TestClass
|
||||
java.lang.OutOfMemoryError: java heap space
|
||||
Dumping heap to java_pid444496.hprof ...
|
||||
Heap dump file created [1018925828 bytes in 1.442 secs]
|
||||
Exception in thread "main" java.lang.OutOfMemoryError: java heap space
|
||||
at TestClass.main(TestClass.Java:8)
|
||||
```
|
||||
|
||||
[There are tools][6] to look at this .hprof file to understand what went wrong.
|
||||
|
||||
### Conclusion
|
||||
|
||||
By understanding and using JVM and JVM parameters, both developers and end users can diagnose failures and improve the performance of a Java application. The next time you're working with Java, take a moment to look at the options available to you.

LibreWolf vs Firefox: Comparing the Privacy Heroes of Open-Source Browsers
|
||||
======
|
||||
|
||||
Firefox is one of the best cross-platform [open-source web browsers][1].
|
||||
|
||||
Not to mention, it is the only viable alternative as a Chromium-based replacement. Or, is it?
|
||||
|
||||
LibreWolf is yet another interesting option, which is originally a Firefox fork that attempts to do better than Firefox to enhance privacy/security right out of the box.
|
||||
|
||||
But, is it really useful to choose LibreWolf over Firefox? What are the differences? Let us take a look.
|
||||
|
||||
### The User Interface
|
||||
|
||||
Considering [LibreWolf][2] is a Firefox fork, the user interface is the same with a few subtle changes.
|
||||
|
||||
![Firefox UI][3]
|
||||
|
||||
For instance, it does not feature the link to the Firefox website in the bookmark menu and gets rid of the “Add to Pocket” button.
|
||||
|
||||
Instead, you can find the icon to an extension, and the download manager to the right of the address bar.
|
||||
|
||||
![LibreWolf UI][4]
|
||||
|
||||
Yes, you no longer have to head to the menu to access the downloads.
|
||||
|
||||
If you consider the extras in Firefox as annoyances, LibreWolf should be a clean experience.
|
||||
|
||||
### Search Providers
|
||||
|
||||
By default, Firefox utilizes Google as its search engine, considering they are official partners, i.e., Google pays to be the default search engine.
|
||||
|
||||
![][5]
|
||||
|
||||
While you can easily change the default search provider to DuckDuckGo, Startpage, or anything else, the default remains a big deal for most users.
|
||||
|
||||
When it comes to LibreWolf, the default search engine is DuckDuckGo. It is known to be one of the best privacy-friendly search engines out there.
|
||||
|
||||
![][6]
|
||||
|
||||
It should be noted that the privacy-focused search engines may not be as good as Google for some use-cases. So, if the search engine choice does not bother you, Firefox can be just fine.
|
||||
|
||||
However, if you want to keep your search history private to yourself, LibreWolf’s default search provider can prove to be a better option.
|
||||
|
||||
### Hardened Privacy
|
||||
|
||||
Mozilla Firefox is incredibly customizable. If you want to put the effort, you can enhance the digital privacy on Firefox.
|
||||
|
||||
However, if you want to avoid investing a lot of time tweaking the Firefox experience, LibreWolf can be a good pick.
|
||||
|
||||
LibreWolf features some of the best settings out-of-the-box to ensure you get rid of the trackers online and have a safe online experience.
|
||||
|
||||
For instance, it features the UBlock content blocker by default to eliminate trackers/scripts that track your online activities. The default search engine as DuckDuckGo also helps to an extent.
|
||||
|
||||
![][7]
|
||||
|
||||
Furthermore, LibreWolf enables the Strict mode of Firefox’s Enhanced Tracking Protection. In other words, it blocks trackers aggressively, which might result in some web pages not working as expected.
|
||||
|
||||
![][8]
|
||||
|
||||
While LibreWolf recommends not changing these settings, you can choose to use Firefox if you notice web pages breaking with the settings.
|
||||
|
||||
Firefox uses the basic protection enabled to get rid of common trackers without breaking the user experience on web pages.
|
||||
|
||||
In addition to these settings, LibreWolf also deletes cookies and site data upon exit by default. This can be annoying if you want to stay signed in to websites and resume your browsing session quickly.
|
||||
|
||||
When it comes to Firefox, it does feature the same option, but it remains disabled by default. So, if you want to avoid tweaking built-in settings for a convenient experience, you should pick Firefox.
|
||||
|
||||
![][9]
|
||||
|
||||
No wonder why Firefox is still one of the [best browsers available for Linux][10]. Most of the users prefer convenience to enhance privacy while still being able to use the browser cross-platform.
|
||||
|
||||
### Google Safe Browsing
|
||||
|
||||
Google Safe Browsing is a useful service that warns/flags suspicious websites for malicious activities.
|
||||
|
||||
Most browsers use it to enable a safe user experience. You do not need to be an expert at spotting sites with phishing/malware, Google Safe Browsing helps you detect them.
|
||||
|
||||
Mozilla Firefox uses it with a different name “**Phishing Protection**“, which is enabled by default.
|
||||
|
||||
However, with LibreWolf the Google Safe Browsing service comes disabled by default to avoid connecting to Google services. You can enable it, but it is not something that users look for when setting up their browsers.
|
||||
|
||||
![][11]
|
||||
|
||||
So, if you want additional help in avoiding malicious sites, Firefox should be a good out-of-the-box solution. And, if you know what you’re doing, you can go with LibreWolf, and enable the setting when/if required.
|
||||
|
||||
### Extras
|
||||
|
||||
LibreWolf gets rid of any additional offerings on Firefox.
|
||||
|
||||
For instance, LibreWolf does not have any connections to the Mozilla server by default. Some of the changes that it reflects include:
|
||||
|
||||
* You do not get the sync/sign-in functionality with LibreWolf.
|
||||
* No Add to Pocket button
|
||||
* You do not load the Mozilla add-ons/themes on the extensions page.
|
||||
|
||||
|
||||
|
||||
![][12]
|
||||
|
||||
If you want to use the Mozilla account to sync your history/bookmarks and browser data, Firefox is the best bet. There’s also Firefox VPN, if you prefer using it.
|
||||
|
||||
![][13]
|
||||
|
||||
However, if you do not trust any of the Mozilla services and prefer to sever any connections to them on your browser, LibreWolf is your friend.
|
||||
|
||||
### Cross-Platform Support
|
||||
|
||||
Firefox is available for Android and iOS, and works well with a wide range of screen sizes and devices.
|
||||
|
||||
Unfortunately, LibreWolf is limited to the desktop platforms like macOS, Windows, OpenBSD, and Linux.
|
||||
|
||||
### Community-Based vs Backed by Organization
|
||||
|
||||
[LibreWolf][14] is a community-powered project maintained by a few passionate contributors to promote privacy, security, and user freedom.
|
||||
|
||||
If you prefer what LibreWolf has to offer, it should not be a problem to go with it. Even with a small team, they follow the latest Firefox releases and push an update as soon as possible.
|
||||
|
||||
In contrast, the Mozilla Foundation is a much bigger organization and has been setting extraordinary examples to promote customizability, privacy, and security.
|
||||
|
||||
You will be receiving updates faster than LibreWolf, which is an important aspect if you are worried about your browser’s security.
|
||||
|
||||
There are no critical downsides of Firefox being a part of something bigger, but there may be some future decisions (or changes) that you may not like, put forward by Mozilla for its users.
|
||||
|
||||
But, LibreWolf as a community project will keep user preferences as its priority.
|
||||
|
||||
### Final Verdict
|
||||
|
||||
If convenience is your thing where you require sync/sign-in account features, Mozilla-specific offerings, and essential privacy protections, Mozilla Firefox should suit you better.
|
||||
|
||||
In case you do not want cloud-sync features, extras, and hardcore privacy-focused settings out of the box, LibreWolf will be the perfect solution.
|
||||
|
||||
Performance-wise, both should offer similar experiences. The benchmarks test (Basemark 3.0, Speedometer 2.0) didn’t work with LibreWolf for some reason, so I did not include any performance comparison chart.
|
||||
|
||||
I will prefer using Firefox because I do need the convenience of account-based sync without aggressive blocking capability. However, LibreWolf is a solid alternative for those who want to switch away from Firefox or just want to try something that’s laser-focused on user freedom and privacy.

3-2-1 Backup plan with Fedora ARM server
|
||||
======
|
||||
|
||||

|

|
||||
Fedora Server Edition works on Single Board Computers (SBC) like Raspberry Pi. This article is aimed at data backup and restoration of personal data for users who want to take advantage of solid server systems and built-in tools like Cockpit. It describes 3 levels of backup.
|
||||
|
||||
### Pre-requisites
|
||||
|
||||
To use this guide, all you need is a working Fedora Linux workstation and the following items.
|
||||
|
||||
* You should read, understand, and practice the requirements as documented in the Fedora Docs for [server installation][4] and [administration][5]
|
||||
* An SBC (Single Board Computer), tested for Fedora Linux. Check [hardware status here][6].
|
||||
* [Fedora ARM][7] [server][7] raw image & ARM image installer
|
||||
* A choice of microSD Card (64 GB / Class 10) and SSD device
|
||||
* Ethernet cable / DHCP reserved IP or static IP
|
||||
* A Linux client workstation with ssh keys prepared
|
||||
* Make a choice of cloud storage services
|
||||
* Have an additional Linux workstation available
|
||||
|
||||
|
||||
|
||||
With this setup, I opted for Raspberry Pi 3B+/4B+ (one for hot-swap) because of the price and availability at the time of writing this article. While the Pi server is remotely connected using Cockpit, you can position the Pi near the router for a neat set-up.
|
||||
|
||||
### Harden server security
|
||||
|
||||
After following through with server installation and administration on the SBC, it is a good practice to harden the server security with firewalld.
|
||||
|
||||
You must configure the firewall as soon as the server is online before connecting the storage device to the server. Firewalld is a zone-based firewall. It creates one pre-defined zone ‘FedoraServer’ after following through with the installation and administration guide in the Fedora Docs.
|
||||
|
||||
#### Rich rules in firewalld
|
||||
|
||||
Rich rules are used to block or allow a particular IP address or address range. The following rule accepts SSH connections only from the host with the registered IP (of client workstation) and drops other connections. Run the commands in Cockpit Terminal or terminal in client workstation connect to the server via ssh.
|
||||
|
||||
```
|
||||
|
||||
firewall-cmd --add-rich-rule='rule family=ipv4 source address=<registered_ip_address>/24 service name=ssh log prefix="SSH Logs" level="notice" accept'
|
||||
|
||||
```
|
||||
|
||||
#### Reject ping requests from all hosts
|
||||
|
||||
Use this command to set the icmp reject and disallow ping requests
|
||||
|
||||
```
|
||||
|
||||
firewall-cmd --add-rich-rule='rule protocol value=icmp reject'
|
||||
|
||||
```
|
||||
|
||||
To carry out additional firewall controls, such as managing ports and zones, please refer to the link below. Please be aware that misconfiguring the firewall may make it vulnerable to security breaches.
|
||||
|
||||
[Managing firewall in Cockpit][8]
|
||||
[firewalld rules][9]
|
||||
|
||||
### Configure storage for file server
|
||||
|
||||
The next step is to connect a storage device to the SBC and partition a newly attached storage device using Cockpit. With Cockpit’s graphical server management interface, managing a home lab (whether a single server or several servers) is much simpler than before. Fedora Linux server offers Cockpit as standard.
|
||||
|
||||
In this setup, an SSD device, powered by the USB port of the SBC, is placed in service without the need for an additional power supply.
|
||||
|
||||
* Connect the storage device to a USB port of the SBC
|
||||
* After Cockpit is running (as set up in the pre-requisites), visit **ip-address-of-machine:9090** in the web browser of your client workstation
|
||||
* After logging into Cockpit, click ‘Turn on administrative access’ at the top of the Cockpit page
|
||||
* Click the “Storage” on the left pane
|
||||
* Select the device under “Drives” section to format and partition a blank storage device
|
||||
|
||||
|
||||
|
||||
![Cockpit Storage management][10]
|
||||
|
||||
* On the screen of the selected storage device create a new partition table or format and create new partitions. When prompted to initialize disk, in the “Partitioning” type, select GPT partition
|
||||
* For a file system type from the drop-down list (XFS and ext4), choose ext4. This is suitable for an SBC with limited I/O capability (like USB 2.0 port) and limited bandwidth (less than 200MB/s)
|
||||
|
||||
|
||||
|
||||
![Create a partition in Cockpit][11]
|
||||
|
||||
* To create a single partition taking up all the storage space on the device, specify its mount point, such as “/media” and click “Ok”
|
||||
* Click “Create partition”, which creates a new partition mounted at “/media”.
|
||||
|
||||
|
||||
|
||||
### Create backups and restore from backups
|
||||
|
||||
Backups are rarely one-size-fits-all. There are a few choices to make such as where the data is backed up, the steps you take to backup data, identify any automation, and determine how to restore backed-up data.
|
||||
|
||||
![Backup workflow – version 1.0][12]
|
||||
|
||||
#### Backup 1. rsync from client to file server (Raspberry Pi)
|
||||
|
||||
The command used for this transfer was:
|
||||
|
||||
```
|
||||
|
||||
rsync -azP ~/source syncuser@host1:/destination
|
||||
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
Options:
|
||||
-a, --archive
|
||||
-z, --compress
|
||||
-P, --progress
|
||||
|
||||
```
|
||||
|
||||
To run rsync with additional options, set the following flags:
|
||||
|
||||
Update destination files in-place
|
||||
|
||||
```
|
||||
|
||||
--inplace
|
||||
|
||||
```
|
||||
|
||||
Append data onto shorter files
|
||||
|
||||
```
|
||||
|
||||
--append
|
||||
|
||||
```
|
||||
|
||||
Source-side deduplication combined with compression is the most effective way to reduce the size of data to be backed up before it goes to backup storage.
|
||||
|
||||
I run this manually at the end of the day. Automation scripts are advantageous once I settled in with the cloud backup workflow.
|
||||
|
||||
For details on rsync, please visit the Fedora magazine article [here][13].
|
||||
|
||||
#### Backup 2. rsync from file server to primary cloud storage
|
||||
|
||||
Factors to consider when selecting cloud storage are;
|
||||
|
||||
* Cost: Upload, storage, and download fee
|
||||
* rsync, sftp supported
|
||||
* Data redundancy (RAID 10 or data center redundancy plan in place)
|
||||
* Snapshots
|
||||
|
||||
|
||||
|
||||
One of the cloud storage fitting these criteria is Hetzner’s hosted Nextcloud – [Storage Box][14]. You are not tied to a supplier and are free to switch without an exit penalty.
|
||||
|
||||
##### Generate SSH keys and create authorized key files in the file server
|
||||
|
||||
Use ssh-keygen to generate a new pair of SSH keys for the file server and cloud storage.
|
||||
|
||||
```
|
||||
|
||||
ssh-keygen
|
||||
Generating public/private rsa key pair.
|
||||
Enter file in which to save the key . . .
|
||||
|
||||
```
|
||||
|
||||
Insert the required public SSH keys into a new local authorized_keys file.
|
||||
|
||||
```
|
||||
|
||||
cat .ssh/id_rsa.pub >> storagebox_authorized_keys
|
||||
|
||||
```
|
||||
|
||||
##### Transfer keys to cloud storage
|
||||
|
||||
The next step is to upload the generated authorized_keys file to the Storage Box. To do this, create the directory .ssh with permission 700 and create the file authorized_keys with the public SSH keys and permission 600. Run the following command.
|
||||
|
||||
```
|
||||
|
||||
echo -e "mkdir .ssh \n chmod 700 .ssh \n put storagebox_authorized_keys .ssh/authorized_keys \n chmod 600 .ssh/authorized_keys" | sftp <username>@<username>.your-storagebox.de
|
||||
|
||||
```
|
||||
|
||||
##### Use rsync over ssh
|
||||
|
||||
Use rsync to synchronize the current state of your file directories to Storage Box.
|
||||
|
||||
```
|
||||
|
||||
rsync --progress -e 'ssh -p23' --recursive <local_directory> <username>@<username>.your-storagebox.de:<target_directory>
|
||||
|
||||
```
|
||||
|
||||
This process is called a push operation because it “pushes” a directory from the local system to a remote system.
|
||||
|
||||
##### Restore a directory from cloud storage
|
||||
|
||||
To restore a directory from the Storage Box, swap the directories:
|
||||
|
||||
```
|
||||
|
||||
rsync --progress -e 'ssh -p23' --recursive <username>@<username>.your-storagebox.de:<remote_directory> <local_directory>
|
||||
|
||||
```
|
||||
|
||||
#### Backup 3. Client backup to secondary cloud storage
|
||||
|
||||
[Deja Dup][15] is in the Fedora software repo, making it a quick backup solution for Fedora Workstation. It handles the GPG encryption, scheduling, and file inclusion (which directories to back up).
|
||||
|
||||
![Backing up to the secondary cloud][16]
|
||||
|
||||
![Restoring files from cloud storage][17]
|
||||
|
||||
### Archive personal data
|
||||
|
||||
Not every data needs a 3-2-1 backup strategy. That is personal data share. I repurposed a hand-me-down laptop with a 1TB HDD as an archive of personal data (family photos).
|
||||
|
||||
Go to “Sharing” in settings (in my case, the GNOME file manager) and toggle the slider to enable sharing.
|
||||
|
||||
![][18]
|
||||
|
||||
Turn on “file sharing”, “Networks” and “Required password”, which allows you to share your public folders with other workstations on your local network using WebDAV.
|
||||
|
||||
![][19]
|
||||
|
||||
### Prepare fallback options
|
||||
|
||||
Untested backups are no better than no backups at all. I take the ‘hot swap’ approach in a home lab environment where disruptions like frequent power outages or liquid damages do happen. However, my recommendations are far from disaster recovery plans or automatic failover in corporate IT.
|
||||
|
||||
* Dry run restoration of files on a regular basis
|
||||
* Backup ssh/GPG keys onto an external storage device
|
||||
* Copy a raw image of the Fedora ARM server onto an SD card
|
||||
* Keep snapshots of full backups at primary cloud storage
|
||||
* Automate backup process to minimize human error or oversight
|
||||
|
||||
|
||||
|
||||
### Track activity and troubleshoot with Cockpit
|
||||
|
||||
As your project grows, so does the number of servers you manage. Activity and alert tracking in Cockpit ease your administrative burden. You can achieve this in three ways using Cockpit’s graphical interface.
|
||||
|
||||
#### SELinux menu
|
||||
|
||||
How to diagnose network issues, find logs and troubleshoot in Cockpit
|
||||
|
||||
* Go to SELinux to check logs
|
||||
* Check “solution details”
|
||||
* Select “Apply this solution” when necessary
|
||||
* View automation script and run it if necessary
|
||||
|
||||
|
||||
|
||||
![SELinux logs][20]
|
||||
|
||||
#### Network or storage logs
|
||||
|
||||
Server logs track detailed metrics that correlate CPU load, memory usage, network activity, and storage performance with the system’s journal. Logs are organized under the network or storage dashboard.
|
||||
|
||||
![Storage logs in Cockpit][21]
|
||||
|
||||
#### Software updates
|
||||
|
||||
Cockpit helps security updates on preset time and frequency. You can run all updates when you need them.
|
||||
|
||||

|
||||
|
||||
Congratulations on setting up a file/backup server with the Fedora ARM server edition.

How to Upgrade to Ubuntu 22.04 “Jammy Jellyfish” From Ubuntu 20.04 LTS
|
||||
======
|
||||
HERE ARE THE COMPLETE STEPS AND PRECAUTIONS YOU NEED TO TAKE BEFORE
|
||||
UPGRADING TO UBUNTU 22.04 LTS FROM UBUNTU 20.04 LTS.
|
||||
[Ubuntu 22.04 LTS Jammy Jellyfish][1] releases on April 21, 2022. I recommend you wait for a month or two after April 21st to upgrade. Ideally, it would be best if you plan to Upgrade to any major release after the first point release.
|
||||
|
||||
But if you are in a hurry or want to experience the stunning changes and features that Ubuntu 22.04 brings to the table, then read below the steps required for a flawless upgrade process.
|
||||
|
||||
### Before Upgrade
|
||||
|
||||
For any upgrade, it is always wiser to follow some best practices. These prevent some post-upgrade problems and lead to a successful upgrade process.
|
||||
|
||||
* Backup data to another drive or USB storage from your home directory includes your pictures, videos, or other personal files.
|
||||
* Keep a [LIVE USB ready with Ubuntu][2] if you run into an unstable system.
|
||||
* If you upgrade to a GNOME workstation, disable all the GNOME extensions because they will be incompatible as they work with GNOME 3.36+.
|
||||
* After a successful upgrade, you can enable the extensions one at a time.
|
||||
* Ensure that your system is up to date with packages by running the command `sudo apt update && sudo apt upgrade`
|
||||
* Close all your running applications.
|
||||
* Restart your system.
|
||||
|
||||
|
||||
|
||||
With that said, if you are ready, then follow the instructions below to Upgrade to Ubuntu 22.04 From Ubuntu 20.04 LTS.
|
||||
|
||||
### Upgrade to Ubuntu 22.04 from Ubuntu 20.04 and Ubuntu 21.10
|
||||
|
||||
#### Before April 21, 2022
|
||||
|
||||
If you want to upgrade before the release day, open a terminal window and run the following command.
|
||||
|
||||
```
|
||||
|
||||
sudo do-release-upgrade -d
|
||||
|
||||
```
|
||||
|
||||
![Upgrade to Ubuntu 22.04 LTS from Ubuntu 20.04 LTS][3]
|
||||
|
||||
The above command will override the system “focal” branches with “jammy” to get the new packages. Not only that, but the command will also disable all third-party PPA that you may have added over the years.
|
||||
|
||||
Furthermore, the command will take some time to finish depending on your internet speed.
|
||||
|
||||
In addition to that, keep a watch on the terminal for occasional prompts which require your input as Y/N. Also, if you cancel the upgrade process midway, the third party PPA will not be enabled. So, you have to enable them manually.
|
||||
|
||||
![Summary of the upgrade][4]
|
||||
|
||||
Finally, the command will calculate the size of the upgrade and give you the estimated time required with a summary as shown below. Please read it carefully and give your permission to upgrade to Ubuntu 22.04 LTS Jammy Jellyfish.
|
||||
|
||||
[][5]
|
||||
|
||||
SEE ALSO: Ubuntu 22.04 Jammy Jellyfish Daily Builds Are Now Available
|
||||
|
||||
After the upgrade process is complete, restart your system and enjoy the exciting Ubuntu 22.04 LTS.
|
||||
|
||||
#### After April 21, 2022
|
||||
|
||||
On the day or after April 21, 2022, Ubuntu will not give you any visual upgrade prompt for an upgrade until the first point release in July 2022 because the first point release is considered the most stable version after initial bugs are ironed out.
|
||||
|
||||
That said, you either wait until July, or you can force the upgrade. How? Open the Software and Updates, and go to the Updates tab. And change “notify me of new ubuntu version” to “any new version”.
|
||||
|
||||
Once you do that, you should see a prompt for an upgrade on the desktop. Follow the on-screen instructions and continue with the upgrade process.
|
||||
|
||||
The prompt also calculates the list of packages required to upgrade with the needed time, so read the updater output carefully. Once you are ready, start the process.
|
||||
|
||||
Finally, after the upgrade process is finished, reboot the system to enjoy the brand new Ubuntu 22.04 LTS Jammy Jellyfish.
|
||||
|
||||
#### Upgrade to Ubuntu 22.04 from Ubuntu 21.10
|
||||
|
||||
You can follow the above exact instructions for Ubuntu 21.10 as well. There are no extra steps required to Upgrade to Ubuntu 22.04 from Ubuntu 21.10.
|
||||
|
||||
#### How long does the upgrade to the Ubuntu 22.04 process take?
|
||||
|
||||
As per my test, the default install requires a little more than 30 minutes of total time to finish the entire upgrade process. It might be higher for your system based on how many software of packages you installed plus the age of your installation. So plan your time accordingly.
|
||||
|
||||
### Conclusion
|
||||
|
||||
Finally, I hope these steps help you successfully upgrade your Ubuntu system to Jammy Jellyfish. If you are planning to upgrade, I wish you all the best.
|
||||
|
||||
Do let me know in the comment box below how the upgrade process goes.

Disable Animations in Cinnamon Desktop to Slightly Speed Up Your Linux Mint System
|
||||
======
|
||||
|
||||
Let’s face it.
|
||||
|
||||
Cinnamon is already a lightweight desktop environment when compared to the likes of GNOME. But it may not be as light on resources as Xfce.
|
||||
|
||||
If you have a system which is low on hardware and you want a little bit of performance boost without switching to an alternative desktop environment (DE) like Xfce or window manager (WM) like [Sway][1] or [Fluxbox][2].
|
||||
|
||||
Let me share a neat little trick that should help you speed up Linux Mint but only slightly.
|
||||
|
||||
### Disabling animation effects in Cinnamon desktop
|
||||
|
||||
_**First thing first, you must not expect a drastic improvement in overall desktop performance with this trick. Here’s why!**_
|
||||
|
||||
These animations or effects (as it is called in Mint) are noticed when you open, close applications windows, use the menu, have dialogue box popped up etc. Since these events do not happen continuously, you don’t get a constant boost.
|
||||
|
||||
Disabling these effects may help reduce the stutters if your system is really struggling. In those cases, every single bit helps. Let’s see how to do this!
|
||||
|
||||
Open the menu and look for effects here.
|
||||
|
||||
![Accessing Effects settings in Linux Mint Cinnamon][3]
|
||||
|
||||
It opens the ‘effects’ settings window and you’ll be at the ‘Enable Effects’ tab. You’ll have the options to disable (or enable) various available animation effects here.
|
||||
|
||||
![Disable animations in cinnamon Linux Mint Cinnamon Desktop][4]
|
||||
|
||||
You can choose to disable some or all effects.
|
||||
|
||||
If you go to the Customize tab, you can customize various effects you saw in the ‘Enable Effects’ tab.
|
||||
|
||||
![Customizing window animation Cinnamon in Linux mint][5]
|
||||
|
||||
The first column is the name of the effect, second one is the type of animation, third one is how the animation progresses and in the last one, you can configure how long the animation will take to complete.
|
||||
|
||||
If you select None, easeNone and 0 duration, it is equivalent to disabling the effect. Though, using the disable option in the other tab is an easier option.
|
||||
|
||||
### Is it worth the effort?
|
||||
|
||||
I wrote this tip because a reader asked if it was possible to customize Cinnamon and disable the animations.
|
||||
|
||||
Quite honestly, it doesn’t take much effort and it doesn’t make much difference. You’ll hardly notice the visual impacts or even the performance improvements.
|
||||
|
||||
However, if your system is struggling a lot, every tiny bit helps. You can also try using lightweight applications that consume fewer system resources. That may also help you a bit.
|
||||
|
||||
Do you have any similar small, ninja tips? Do share with me in the comment sections.

How I scan family photos on Linux
|
||||
======
|
||||
With Linux, I can connect with my ancestors in unexpected ways.
|
||||
|
||||
![Camera][1]

|
||||
|
||||
Linux isn't just something that runs on servers and powers the internet. It's a safe place for your data, your family history and memories, working or having fun, and real life.
|
||||
|
||||
Case in point: Right now I'm in the middle of a project scanning old family photos. I have been using Fedora Linux with the GNOME desktop for a few years, so I didn't have to install any additional software packages. I just plug my scanner into the USB port, start up the scanning software (Document Scanner), and I'm good to go. Keep reading to see how I did it.
|
||||
|
||||
### Digitizing memories
|
||||
|
||||
Many people are interested in learning more about their family history, ancestry, and legacy. With the technology now available, digitizing old artifacts has become a common practice. Whether it's your 1980s cassette collection, high school artwork, or old family photos, putting them into a digital format is a modern method of preservation and future proofing.
|
||||
|
||||
My mom recently gave me some photos of some of my ancestors, so I have several images that I want to preserve. Scanning them not only provides a certain sense of permanence but also allows me to manipulate them in ways that were unheard of in the era when they were captured. For instance, I have a photo of my grandfather, who unfortunately passed a few years before my birth. By digitizing his photo, I can zoom in, get to know him, and maybe relate to him in a way that otherwise would be impossible.
|
||||
|
||||
### Workflow
|
||||
|
||||
The first thing to do is plug my Canon scanner into the USB port. When I open Document Scanner, it detects my Canon LiDE 210 scanner. Next, I place the photo onto the flatbed scanner. I adjust the settings for 2400 DPI image resolution to ensure I capture every detail.
|
||||
|
||||
Then I click scan. At this resolution the scan may take a while, but once it is complete, I can crop the image as needed and save it.
|
||||
|
||||
By the way, as I scan my photos and write this article, I'm also enjoying some of my favorite music with [Clementine][2], an open source audio player—on the same computer. Performance hit? Not a bit!
|
||||
|
||||
Once scanning is complete, I've also got the option of cropping the image and saving it as a PDF, JPG, or whatever format I choose.
|
||||
|
||||
### Real life
|
||||
|
||||
Allow me to introduce my grandfather and my Uncle George, circa 1944. George was a World War II vet having seen action in Europe battling the Nazis. My grandfather, on the right, was the foreman of a southeastern North Carolina lumber mill. While he didn't see the battlefield, he was in charge of captured Nazi POWs assigned to work at his mill. He described them as young boys that just wanted to go home to their families.

|
||||
|
||||
### Final thoughts
|
||||
|
||||
As a dedicated Linux desktop user, I sometimes hear people say they don't use Linux because there are certain tasks it can't perform. Linux is all I use, and I haven't had that problem for roughly 14 years and counting. Whether you're looking for a pleasant pastime or a way to be more productive, there's likely a solution for you that runs on Linux.

Difference Between Ubuntu 22.04 and Ubuntu 20.04 LTS
|
||||
======
|
||||
A LIST OF 10 SIGNIFICANT FEATURE DIFFERENCES BETWEEN UBUNTU 20.04 AND
|
||||
UBUNTU 22.04 LTS FOR FOLKS TRANSITIONING FROM LTS TO LTS.
|
||||
If you are a [Ubuntu 20.04 LTS Focal Fossa][1] user and plan to upgrade or install the latest [Ubuntu 22.04 LTS “Jammy Jellyfish”][2], this guide is for you. The primary aspect is there are significant and structural changes between these two LTS versions which is somewhat rare in terms of LTS releases. In one go, a lot changed if you compare both the LTS releases.
|
||||
|
||||
So, with that in mind, in this guide, we give you ten pointers that address the fundamental changes from an average user perspective and give you a heads up before you try the new Jammy Jellyfish.
|
||||
|
||||
### Ubuntu 22.04 LTS vs Ubuntu 20.04 LTS – Feature Difference
|
||||
|
||||
#### 1\. Logo, Colors and Plymouth
|
||||
|
||||
The first visual change that you notice is the base accent colour of Ubuntu changes to more “Orange” compared to two earlier “brown-orange”. Also, Canonical changed the Ubuntu official logo from this release onwards, and it is visible right from the Plymouth animation while booting. The new logo may look a little strange while you look at it for the first time, but it grows into you, eventually. I feel it’s a distinct logo in its way.
|
||||
|
||||
![New Ubuntu logo and Plymouth][3]
|
||||
|
||||
#### 2\. Installation
|
||||
|
||||
The default Ubuntu installer did not see any additional changes. We hoped that the new [Flutter based installer][4] would land, but it didn’t. With that said, the steps to installation remain the same. The only difference you may notice is the accent colour and cosmetic changes on the dialogue boxes and controls. Functionality wise, there is no change in the installation steps.
|
||||
|
||||
![Colour differences between two LTS Versions][5]
|
||||
|
||||
#### 3\. Lock and Login Screen, Desktop First look and Wallpaper
|
||||
|
||||
Furthermore, the lock and login screen colour gradient changes with more fine and borderless controls for the password box. The apparent difference is the stunning Jammy Jellyfish default wallpaper when you first log in. The desktop “Home” shortcut is renamed as Home than that of your username, and the Trash shortcut now goes to the left dock with a separator in the new Ubuntu 22.04 LTS.
|
||||
|
||||
In addition to that, the top bar didn’t change much. However, the system tray menu is little organised with more spacing and separators. There are mainly the changes coming from the [GNOME 42][6] changes.
|
||||
|
||||
The Calendar menu remained almost the same between both the LTS versions.
|
||||

|
||||
|
||||
#### 4\. Desktop Layouts and GNOME Version Upgrades
|
||||
|
||||
The significant difference that users would see visually is the GNOME version change – GNOME 3.36 vs the GNOME 42. This is the significant difference that all users migrating to current LTS would face. The Ubuntu 22.04 LTS with GNOME 42 brings a horizontal workspace view alongside the horizontal application view. So, it would be a little weird to feel first time migrating from vertical to horizontal gestures. But you get used to it within a day or two.
|
||||
|
||||
If you use touch-based Laptops or screens, then the GNOME 42 gestures would give you some fluid feel with a bit of learning. Here’s how the desktop, applications and workspace view looks side by side.

||||

||||

|
||||

||||

|
||||
|
||||
#### 5\. New Appearance Style with Accent Color
|
||||
|
||||
Moreover, one particular change which I would like to highlight here is new settings for light and dark modes. Earlier Ubuntu had three options for desktop looks – light, dark and a mixed one – Standard. This is completely changed and replaced by the GNOME 42’s built-in light and dark mode. In addition to that, a new Accent colour option is introduced (which is not part of vanilla GNOME 42) that enables you to change the colour across the desktop based on a selection of palettes.
|
||||
|
||||
However, you can not choose the custom accent colour yet, like KDE Plasma 🥰. Most of these changes come with the recent libadwaita and GTK4 port of GNOME Shell and native applications.
|
||||
|
||||
When you apply the dark mode in Ubuntu 22.04 – it applies automatically to all the supported applications. This is one of the fundamental differences with the Ubuntu 20.04 LTS.
|
||||
|
||||
![Accent Color and other changes][12]
|
||||
|
||||
![How Accent colour change impact looks in Ubuntu 22.04 LTS][13]
|
||||
|
||||
#### 6\. File Manager
|
||||
|
||||
The Files file manager version changes from 3.36.x to 42 in this release. The difference you see is the more compact design, well-defined spacing between controls and texts, and the top bar widgets style, thanks to GTK4 and underlying bug fixes. The address bar in Files is a little different, with a separator between directories, and the hamburger menu is at the end. Although, these minor changes would not impact much, and you may not feel much difference between the two LTS releases.
|
||||
|
||||
![Files Difference – Ubuntu 20.04 vs 22.04][14]
|
||||
|
||||
#### 7\. Screenshot Workflow difference between Ubuntu 22.04 and 20.04
|
||||
|
||||
Another notable change that requires a little learning for migrating users is how screenshots are captured. It changes completely. Earlier, you hit print-screen from the keyboard to take a screenshot and save the image file automatically in your Pictures folder. The workflow is different now with GNOME 42’s built-in screenshot and screen-recorder tool.
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
So, when you try to take a screenshot in Ubuntu 22.04 LTS, you see a screen below which gives you all the options, such as a screenshot of an area, an entire desktop or a specific window. Moreover, you have the option to show the cursor in a screenshot or want to record the screen. And when you hit the capture button, the tool saves the image file in the Pictures folder and in your clipboard.
|
||||
|
||||
![New Screenshot tool in Ubuntu 22.04 LTS][16]
|
||||
|
||||
Overall, an additional step change for your earlier workflow.
|
||||
|
||||
You get a new context menu, “Take a screenshot”, on the top bar right-click menu of all the application windows.
|
||||
|
||||
![Take Screenshot option in top bar menu][17]
|
||||
|
||||
#### 8\. Firefox Web Browser as Snap in Ubuntu 22.04
|
||||
|
||||
In addition to the above changes, the Firefox is now a snap version in Ubuntu 22.04 LTS if you compare it with the prior LTS version. The Firefox 97 in Ubuntu 20.04 was a deb package. So, if you are an average user, you may not see much difference.
|
||||
|
||||
However, Firefox Snap runs in a sandbox mode, which means users may face trouble while installing GNOME Extensions and may feel slow performance due to Snap in the same hardware used by Ubuntu 20.04 LTS.
|
||||
|
||||
I think it would be interesting to see how this significant snap migration of the most used applications of Ubuntu plays out in the coming days.
|
||||
|
||||
#### 9\. Difference in Settings Window between Ubuntu 22.04 and 20.04
|
||||
|
||||
Furthermore, a new panel is introduced in Settings, i.e. Multitasking. The Multitasking panel gives you options to tweak the hot corners and active screen edges. In addition to that, you can now specify the fixed number of workspace you want with the option to remove the empty workspace automatically. Other than that, if you use multiple displays, you have now options to show workspaces in the primary display or all displays.
|
||||
|
||||
![New Multitasking Panel in Settings][18]
|
||||
|
||||
#### 10\. Flavours and Application Updates
|
||||
|
||||
In addition to the above differences, the Software application changes bring different responsive looks and adapt to any form factor. The Software also brings a more different home page with the arrangement of applications as per categories and editor choice section.
|
||||
|
||||
Furthermore, the details page of any software shows essential information in a distinguishable manner with details such as total download size, ratings, safe marker and image carousels.

||||

||||

|
||||
|
||||
Finally, the under the hood differences between these two releases are spread across the packages, official desktop environment flavours and bug fixes. Here’s a quick summary of important packages.
|
||||
|
||||
**20.04** | **22.04**
|
||||
---|---
|
||||
GCC 10.3 | GCC 11.2
|
||||
Hplip 3.20.3 | Hplip 3.21.12
|
||||
LibreOffice 6.4.7 | LibreOffice 7.3.2
|
||||
[not introduced] | Pipewire 0.3.48
|
||||
Python3 3.8.2 | Python3 3.10.1
|
||||
Samba 4.13 | Samba 4.15
|
||||
Systemd 245.4 | Systemd 249.11
|
||||
|
||||
### Summary
|
||||
|
||||
To conclude the difference between Ubuntu 20.04 LTS and Ubuntu 22.04, I am compelled to say; that it is one of the biggest LTS releases from Ubuntu in terms of visual and feature changes.
|
||||
|
||||
I hope this guide showing the difference between Ubuntu 20.04 LTS and Ubuntu 22.04 gives you and many users a starting point on what to expect on their journey of Ubuntu 22.04 LTS and beyond.
|
||||
|
||||
Cheers.

10 Things to Do After Installing Ubuntu 22.04 [With Bonus Tip]
|
||||
======
|
||||
YOU MAY WANT TO TRY A SUMMARY OF 10 THINGS AFTER INSTALLING UBUNTU 22.04
|
||||
LTS “JAMMY JELLYFISH” (GNOME EDITION).
|
||||
I am sure you are excited to experience the brand new Ubuntu 22.04 LTS and its shiny new features. If you have already installed or upgraded from the prior release, you may want to customise your system before you start using it. Although the customisations are subjective and vary with use cases. However, we give you 10 pointers that you can do after installing Ubuntu 22.04 LTS. I hope it helps.
|
||||
|
||||
### 10 Things to Do After Installing Ubuntu 22.04
|
||||
|
||||
#### 1\. Update Your System
|
||||
|
||||
Firstly, you should do some housekeeping after installing Ubuntu 22.04 LTS. Before you begin using the new system and configuring it, ensure that it is up to date with the latest packages from the Ubuntu Jammy repo. So, open a terminal window and run the below commands. Or, open Software Updater from the search.
|
||||
|
||||
```
|
||||
|
||||
sudo apt update && sudo apt upgrade
|
||||
|
||||
```
|
||||
|
||||
![Update your Ubuntu 22.04 LTS System][1]
|
||||
|
||||
Software application takes some time to load for the first time; hence you must do it as a number one step to save time later. It is best if you wait until the update finishes. Once the update is complete, open the Software App and ensure it completes downloading the app metadata.
|
||||
|
||||
Finally, when everything completes, reboot your system to proceed.
|
||||
|
||||
#### 2\. Opt-In/Opt-Out from data collection and history settings
|
||||
|
||||
Secondly, it’s essential to review the privacy settings before using the system. Because we are all concerned about our usage data, location tracking, etc. So, to check them, open Settings from search and go to Privacy. The items you should review are Location Services and File History usage in your system. Make sure to change them as per your need.
|
||||
|
||||
![Review the privacy settings][2]
|
||||
|
||||
#### 3\. Configure KB shortcuts
|
||||
|
||||
To effectively use Ubuntu 22.04 system, keyboard shortcuts are essential. It helps your work faster. So, ideally, keyboard shortcuts are pre-configured, but you may want to change them based on your habits from `Settings > Keyboard > View and Customize Shortcuts`.
|
||||
|
||||
![Configure Keyboard shortcuts in Ubuntu 22.04][3]
|
||||
|
||||
#### 4\. Prepare for the backup
|
||||
|
||||
If you plan to use the system for a longer duration, it is super important to create a system checkpoint just after installation. Because in the future, if something goes wrong, you can always revert to your system as a fresh install.
|
||||
|
||||
Ubuntu 22.04 comes with the built-in backup tool – Backups. You can go ahead and use it to create a system checkpoint.
|
||||
|
||||
However, we recommend you use the great backup and restore tool TImeshift. It has many additional options and is well documented for heavy usage. To install Timeshift, you can use software or the terminal commands mentioned below.
|
||||
|
||||
After installation, launch Timeshift and follow the on-screen instructions to create a system restore point.
|
||||
|
||||
```
|
||||
|
||||
sudo add-apt-repository -y ppa:teejee2008/ppa
|
||||
sudo apt-get update
|
||||
sudo apt-get install timeshift
|
||||
|
||||
```
|
||||
|
||||
#### 5\. Explore the New Features
|
||||
|
||||
Once you complete the above set of housekeepings, it’s time for you to explore the new features of Ubuntu 22.04. We covered the unique features of Ubuntu 22.04 and its flavours in detail in dedicated posts. You may want to check them out below.

|
||||
|
||||
|
||||
#### 6\. Experience the first-ever Accent Colour in Ubuntu
|
||||
|
||||
In addition to the above items, you may find the new accent colour interesting in this release. This is one of the new features which was due for a long time. So, in the Appearance settings, you can find the selected colour options.
|
||||
|
||||
You can choose your favourite colour and see the selection, the folder icon gradient changes with the colour. However, you can not select the custom colour at the moment. I am sure it will eventually come up in future releases.
|
||||
|
||||
![How Accent colour change impact looks in Ubuntu 22.04 LTS][13]
|
||||
|
||||
#### 7\. Dark Mode and new controls
|
||||
|
||||
Besides that accent colour, this release, alongside GNOME 42, brings new style changes, thanks to GTK4 and libadwaita adoption. With this change, the built-in dark mode can apply across the desktop and application that supports it. Also, the controls such as buttons, notifications, rounded corners, scroll bars, etc. all are more stylish and compact in this release.
|
||||
|
||||
[][12]
|
||||
|
||||
SEE ALSO: Difference Between Ubuntu 22.04 and Ubuntu 20.04 LTS
|
||||
|
||||
All of these together make this release a beautiful one.
|
||||
|
||||
#### 8\. Install GNOME Extensions
|
||||
|
||||
Additionally, you can take advantage of hundreds of excellent GNOME Extensions available. For example, you may want to customise the default Dock, Or, like a super cool blur effect, etc. – you can quickly achieve these using the extensions.
|
||||
|
||||
We list here some of the exciting extensions you may want to try out after installing this release.
|
||||
|
||||
* [Blur My Shell][14] – get an exciting blur effect on the default shell
|
||||
* [Floating Dock][15] – make your dock float wherever you want
|
||||
* Dash to Dock: Enables you to control your Dash across the screen with various options.
|
||||
* Caffeine: Enables you more productively.
|
||||
* [Time ++][16]: Super handy extension to give you an alarm clock, stopwatch, time tracker, Pomodoro, and todo.txt manager – all together.
|
||||
* [NetSpeed][17]: Show your internet download and upload speed in the system tray.
|
||||
|
||||
|
||||
|
||||
Before installing the above extensions, open a terminal prompt and install the chrome-gnome-shell using the below command to enable extensions.
|
||||
|
||||
```
|
||||
|
||||
sudo apt-get install chrome-gnome-shell
|
||||
|
||||
```
|
||||
|
||||
Then go to [https://extensions.gnome.org][18] and enable the extensions for Firefox.
|
||||
|
||||
If you use the Snap version of Firefox, then the extension connectivity won’t work. So, uninstall the Firefox Snap version and use an alternate installation Or use a different browser (Such as Google Chrome, Chromium) that has a .deb version. Or, install the extension using the manual steps [outlined here in this article][19].
|
||||
|
||||
#### 9\. Configure Email Client
|
||||
|
||||
Moreover, a native desktop email client is always preferable over browser-based email access. Hence, I would recommend you configure Thunderbird with your email service provider. The setup is more straightforward and wizard-driven. It helps for offline and drafting work for heavy email users.
|
||||
|
||||
Alternatively, if you do not like Thunderbird, try to check out options – you can read our list of [top free native Linux desktop email clients list][20] and choose your favourite.
|
||||
|
||||
#### 10\. Install some additional packages and Software
|
||||
|
||||
In addition to the above items, you should install some additional packages and software because Ubuntu doesn’t come with extra apps other than the native GNOME applications. We list here some of the important applications needed for basic desktop usage.
|
||||
|
||||
You can install them using the Software application.
|
||||
|
||||
* GIMP – Advanced photo editor
|
||||
* VLC – Media play that plays anything without the need for additional codecs
|
||||
* Google Chrome – Browser for Google users.
|
||||
* Leafpad – A lightweight text editor (even lightweight from default gedit)
|
||||
* Synaptic – A far better package manager
|
||||
|
||||
|
||||
|
||||
Moreover, while installing Ubuntu, if you have not selected to install the restricted software to play audio and video media files, you can do it now. Because GNOME default Video player (Totem) can not play the basic mp4, etc. files without restricted software.
|
||||
|
||||
So, to install them, open the terminal and run the below command to install.
|
||||
|
||||
```
|
||||
|
||||
sudo apt install ubuntu-restricted-extras
|
||||
|
||||
```
|
||||
|
||||
You can now play most video/audio files without any problem in Ubuntu.
|
||||
|
||||
#### Bonus Tip 💡
|
||||
|
||||
Finally, I recommend you set up Flatpak the first time after installing Ubuntu 22.04 LTS. Because over time, I am sure you would install many Flatpak applications.
|
||||
|
||||
To set up Flatpak, [visit this page][21] and follow the instructions.
|
||||
|
||||
Once you complete the setup, I recommend installing the below two Flatpak apps. The Extension application helps you manage the GNOME Extensions installed in your system. Other than that, the Flatseal application helps you manage Flatpak applications’ permissions in a super friendly way.
|
||||
|
||||
* [Flatseal][22] – Manage Flatpak permissions
|
||||
* [Extensions][23] – Manage GNOME extensions
|
||||
|
||||
|
||||
|
||||
### Summary
|
||||
|
||||
Also, one of the crucial debatable things to do after installing Ubuntu 22.04 is to delete Snap. Deleting Snap is a bit advanced process and may lead to an unstable system because of the tight coupling of Snap in Ubuntu.
|
||||
|
||||
That said, I hope this list gives you and new users of Ubuntu some idea about making a productive Ubuntu 22.04 LTS desktop.

Ubuntu 20.04 vs 22.04: What Has Changed Between the Two LTS Releases?
|
||||
======
|
||||
|
||||
Ubuntu 20.04 was an impressive release with a [list of exciting features][1].
|
||||
|
||||
Even with GNOME 3.36 on board, we had a fair share of visual upgrades. Now, Ubuntu 22.04 LTS comes packed with GNOME 42. So, naturally, there should be a variety of visual refinements.
|
||||
|
||||
Not just limited to the look and feel, [Ubuntu 22.04 LTS has numerous interesting features][2] to offer as well.
|
||||
|
||||
Here, I try to compare the feature offerings between the two to help you decide if you should upgrade.
|
||||
|
||||
### 1\. Support Lifespan
|
||||
|
||||
Undoubtedly, both being LTS ([Long-Term Release][3]) versions, you can pick any of them and still be able to use them for a couple of years, at the very least.
|
||||
|
||||
To be accurate, Ubuntu 22.04 will be supported with maintenance updates for **five years** until **April 2027**.
|
||||
|
||||
And, Ubuntu 20.04 LTS will be supported until **2025**, meaning, you have **three more years** of software update support.
|
||||
|
||||
### 2\. Logo and Branding
|
||||
|
||||
Ubuntu’s branding focused on a purple accent for some elements like toggles, sliders, etc. on Ubuntu 20.04 LTS.
|
||||
|
||||
However, with Ubuntu 22.04 LTS, they focused on a different accent color with changes to the icon theme as well.
|
||||
|
||||
Not to forget, the [new Ubuntu 22.04 logo looks weird][4], and as of now, we do not have a proper logo file available to use on images.
|
||||
|
||||
The logo associated with Ubuntu 20.04 was clean, without any solid rectangle structure attached to it.
|
||||
|
||||
![][5]
|
||||
|
||||
Accordingly, the boot animation has changed as well, reflecting the latest branding.
|
||||
|
||||
### 3\. Accent Color Selection
|
||||
|
||||
With Ubuntu 20.04, you couldn’t select custom accent colors. You had to stick with the default or customize things yourself with [GNOME Tweaks][6].
|
||||
|
||||
![Ubuntu 20.04 vs Ubuntu 22.04 \(Appearance setting\)][7]
|
||||
|
||||
However, that changes with Ubuntu 22.04 LTS, you can finally [select additional accent colors in Ubuntu 22.04 LTS][8].
|
||||
|
||||
### 4\. Wallpapers
|
||||
|
||||
![Ubuntu 20.04 vs Ubuntu 22.04 \(Desktop featuring default wallpapers\)][9]
|
||||
|
||||
It is obvious to expect a new wallpaper that reflects the name of the Ubuntu upgrade.
|
||||
|
||||
Ubuntu 22.04 is code named as “**Jammy Jellyfish**“, so the new wallpaper illustrates the same beautifully:
|
||||
|
||||
On the other hand, Ubuntu 20.04 is code named “**Focal Fossa**”, which refers to a cat-like predator based found in Madagascar.
|
||||
|
||||
Both have similar color combinations, but I tend to like the new one.
|
||||
|
||||
### 5\. Log in Screen and Lock screen
|
||||
|
||||
As per the changes to the default theme and accent colors, the choices for the log-in and lock screen have differences.
|
||||
|
||||
Both of the lock screens offer a blurred view of the default wallpapers, with Ubuntu 20.04 turning out to be darker than Ubuntu 22.04.
|
||||
|
||||
![Ubuntu 20.04 vs Ubuntu 22.04 \(Lockscreen\)][10]
|
||||
|
||||
The log in screen is entirely different in Ubuntu 22.04 with a black background, here’s how it looks:
|
||||
|
||||
![Ubuntu 20.04 vs Ubuntu 22.04 \(Log in screen\)][11]
|
||||
|
||||
### 6\. Appearance Settings & Dark Mode Improvements
|
||||
|
||||
Ubuntu 20.04 did feature a dark mode to keep up with modern standards. With Ubuntu 22.04 LTS, the dark mode has improved to provide you with a complete system-wide dark mode experience.
|
||||
|
||||
![Ubuntu 20.04 vs Ubuntu 22.04 \(Appearance settings\)][12]
|
||||
|
||||
Along with the new dark mode implementation, you get to see an entire revamp for the appearance settings, giving you more options in an organized manner.
|
||||
|
||||
Furthermore, you can notice that Ubuntu 22.04 LTS no longer features the standard theme, so it’s either entirely light or dark.
|
||||
|
||||
### 7\. GNOME 42 and the horizontal layout
|
||||
|
||||
Ubuntu 20.04 makes use of GNOME 3.36.8 to provide a stable experience without a lot of appearance tweaks.
|
||||
|
||||
But, all thanks to GNOME 42, the dark mode improvements, appearance tweaks, it’s all part of the [GNOME 42 features][13].
|
||||
|
||||
Not just the visual changes, but the entire workflow should feel a bit different with the revamped activities view, app menu, and further adjustments:
|
||||
|
||||
![Ubuntu 20.04 vs Ubuntu 22.04 \(Activities\)][14]
|
||||
|
||||
The three finger swipe also provides a smooth and rich experience for accessing the activity overview.
|
||||
|
||||
Ubuntu 22.04 did not implement the horizontal dock. But, it’s still a significant change to offer something different for a good user experience.
|
||||
|
||||
The application menu also looks a tad different, including the virtual desktops in the same view compared to Ubuntu 20.04.
|
||||
|
||||
![Ubuntu 20.04 vs Ubuntu 22.04 \(App menu\)][15]
|
||||
|
||||
### 8\. Multitasking Capabilities
|
||||
|
||||
Ubuntu 22.04 now includes a dedicated menu in the system settings to facilitate enhancements to multitasking with the use of Hot Corner, Screen Edges, Workspace tweaks, and more.
|
||||
|
||||
![][16]
|
||||
|
||||
You do not find these options with Ubuntu 20.04 LTS.
|
||||
|
||||
### 9\. Linux kernel version
|
||||
|
||||
Ubuntu 22.04 features multiple Linux Kernel versions as per the product. Ubuntu 22.04 Desktop uses [Linux Kernel 5.17][17].
|
||||
|
||||
The desktop version also uses a rolling HWE kernel for previous-gen hardware based on Linux Kernel 5.15, to exist until the first point release.
|
||||
|
||||
Ubuntu 22.04 server uses non-rolling Linux Kernel 5.15 LTS.
|
||||
|
||||
On the other hand, Ubuntu 20.04.4, features [Linux Kernel 5.13][18] at the time of writing this.
|
||||
|
||||
### 10\. Shrinking the Dock in Ubuntu 22.04
|
||||
|
||||
Surprisingly, you can shrink the dock on Ubuntu 22.04 to change the default look. You need to disable the “Panel” mode under the Dock settings in Appearance tweaks, as shown in the image below:
|
||||
|
||||
![][19]
|
||||
|
||||
It may not be a massive change, but some do appreciate a compact dock, instead of having the dock stick to the entire left side of the screen, ditching the Unity-type look.
|
||||
|
||||
### 11\. Screenshot tool
|
||||
|
||||
Ubuntu 20.04 LTS utilized GNOME’s screenshot tool to get things done. It was a simple and effective tool.
|
||||
|
||||
![][20]
|
||||
|
||||
With GNOME 42 on board, Ubuntu 22.04 LTS has the latest screenshot tool and received upgrades to its UI with a modern layout, and the ability to record the screen as well.
|
||||
|
||||
### 12\. File Manager
|
||||
|
||||
The file manager has a refreshed look/feel compared to Ubuntu 20.04 LTS. Of course, the standard theme on Ubuntu 20.04 can no longer be seen with Ubuntu 22.04 LTS, so that’s a part of the visible change.
|
||||
|
||||
![][21]
|
||||
|
||||
### 13\. Software Center
|
||||
|
||||
Ubuntu 22.04 LTS features an improved software center that provides you more information on the software, clarifying the ratings, project details, download size, status, and more.
|
||||
|
||||
![][22]
|
||||
|
||||
Ubuntu 20.04 LTS did have improvements to it back then, but it is a simpler software center comparatively.
|
||||
|
||||
![Ubuntu 22.04 LTS \(Software Center\)][23]
|
||||
|
||||
### Wrapping Up
|
||||
|
||||
Ubuntu 22.04 LTS is certainly a major overhaul in terms of user experience compared to Ubuntu 20.04.
|
||||
|
||||
Some changes may not be as functional as they look, so as per your preferences, it is best to evaluate your requirements if you want to switch to the latest Ubuntu 22.04 LTS or stick to Ubuntu 20.04 LTS.
|
||||
|
||||
What do you think about the difference between the two LTS releases? Are the differences compelling enough for you to switch? Let me know your thoughts in the comments section below.

Things to do After Installing Ubuntu 22.04
|
||||
======
|
||||
|
||||
_**Here is a list of simple tweaks and things to do after installing Ubuntu 22.04, to get a smoother and better experience.**_
|
||||
|
||||
I presume that you are absolutely new to Ubuntu while sharing these tips. If you are an existing Ubuntu user, some tips may sound too elementary to you. However, you’ll still find a few good tweaks that are specific to the [new Ubuntu 22.04 features][1].
|
||||
|
||||
### Things to do after installing Ubuntu 22.04 LTS “Jammy Jellyfish”
|
||||
|
||||
Again, what I recommend here is based on my experience and preference. Yours could be different from mine. Skim around and see if you get some interesting and useful advice.
|
||||
|
||||
Another thing. Most of the suggestions are for the default GNOME desktop environment. If you are using the default Ubuntu, you should be good. If you have doubt, please [check the Ubuntu version][2] and [desktop environment you are using][3].
|
||||
|
||||
Let’s see them one by one.
|
||||
|
||||
#### 1\. Getting your system ready with updates and repositories
|
||||
|
||||
The first thing you should do after installing Ubuntu is to update it. Linux works on a local database of available packages and it needs to be synced for you to be able to install any software.
|
||||
|
||||
It is straightforward to [update Ubuntu][4]. You can run the software updater from the menu (press the Windows key and search for software updater):
|
||||
|
||||
![][5]
|
||||
|
||||
Now, make sure that you have [universe and multiverse repositories enabled][6]. These repositories should be enabled already, but no harm in verifying that. You’ll have access to a lot more software with these repositories.
|
||||
|
||||
Search for Software & Updates in the menu:
|
||||
|
||||
![][7]
|
||||
|
||||
Check the boxes in front of the repositories:
|
||||
|
||||
![][8]
|
||||
|
||||
#### 2\. Install media codecs to play various kinds of media files
|
||||
|
||||
To play media files like MP3, MPEG4, AVI, etc, you’ll need to install media codecs. Ubuntu doesn’t install it by default because of copyright issues in various countries.
|
||||
|
||||
You can install these media codecs as an individual [using the Ubuntu Restricted Extra package][9]. It installs media codecs and [Microsoft True Type Fonts on your Ubuntu system][10].
|
||||
|
||||
You can install it by using this command:
|
||||
|
||||
```
|
||||
|
||||
sudo apt install ubuntu-restricted-extras
|
||||
|
||||
```
|
||||
|
||||
If you encounter the EULA or the license screen, remember to use the tab key to select between the options and then hit enter to confirm your choice.
|
||||
|
||||
![Press tab to select OK and press enter][11]
|
||||
|
||||
#### 3\. Install applications of your choice from the software center or the web
|
||||
|
||||
A fresh installed Ubuntu system will have only a limited set of necessary applications installed.
|
||||
|
||||
For the rest, you can find them in the software center, through the apt package manager, or get them from their official websites.
|
||||
|
||||
Look into the software center first and see if the application is available here.
|
||||
|
||||
![][12]
|
||||
|
||||
Some applications provide an easy-to-use DEB file on their website. For example, to [install Google Chrome on Ubuntu][13], you can download it from its official website.
|
||||
|
||||
Usually, you double-click on the deb file and install the application using the software center. If it opens the deb file in archive manager, [use this trick][14] to make it work.
|
||||
|
||||
#### 4\. Enjoy gaming on Linux with Steam Proton
|
||||
|
||||
There are plenty of tools that allow you to play games on Linux. Steam is perhaps the most convenient, mainstream way of getting thousands of games.
|
||||
|
||||
[Install Steam on Ubuntu][15] and [enable Steam Play][16]. You should have access to a good set of games, provided your system has enough hardware configuration to run all kinds of games.
|
||||
|
||||
Needs some suggestions? Check this list of [indie games for Linux users][17].
|
||||
|
||||
#### 5\. Get familiar with auto-updates
|
||||
|
||||
Your Ubuntu system automatically checks for system updates and installs them automatically when needed.
|
||||
|
||||
This check happens when your system starts. If you try to perform a system update or install an application at this time, you’ll see a warning or message to wait.
|
||||
|
||||
You can control the auto-updates behavior if you like.
|
||||
|
||||
![][18]
|
||||
|
||||
#### 6\. Give your Ubuntu a different color
|
||||
|
||||
Ubuntu 22.04 gives you the ability to choose a different color than the usual orange. There are nine other colors to choose from. From the Settings-Appearance, select the color you want and it will give change the accent color of your system.
|
||||
|
||||
![][19]
|
||||
|
||||
#### 7\. Get familiar with the new screenshot tool
|
||||
|
||||
Ubuntu 22.04 has a new screenshot tool that also includes the screencast (video recording of desktop) option.
|
||||
|
||||
When you press the Print Screen button to take the screenshot, it opens the UI and gives you the option to take the screenshot of the selected area, entire screen, or current application window. The screenshots are copied to the clipboard and saved to the Screenshots folder under the Pictures directory.
|
||||
|
||||
![][20]
|
||||
|
||||
You can also record the screen with the screencast option available in the same interface (click the video camera icon). It lets you record the entire screen and works very well under Wayland.
|
||||
|
||||
#### 8\. Experiment with the dock
|
||||
|
||||
Go to the Appearance Settings and you’ll see the option for disabling Panel mode.
|
||||
|
||||
![][21]
|
||||
|
||||
This will shrink the launcher on the left side and make it look like the Vanilla GNOME launcher. You should use it with ‘auto-hide’ option for better experience.
|
||||
|
||||
You may [move the launcher to the bottom][22] or the right side if you like. There are plenty of [ways to customize the dock in Ubuntu][23].
|
||||
|
||||
#### 9\. Get GNOME Tweaks tool for additional customization
|
||||
|
||||
Though the system settings application now includes several new options, [GNOME Tweaks still provides additional customization options][24].
|
||||
|
||||
With GNOME Tweaks, you can move the windows control button on the left, change themes, change the lock screen background, etc. More on its usage later. For the moment, just get this tool from the software center or use the apt command.
|
||||
|
||||
![][25]
|
||||
|
||||
#### 10\. Minimize to click
|
||||
|
||||
When you click an icon in the launcher, it opens the application. You click the icon again and nothing happens.
|
||||
|
||||
I don’t like this. I prefer that when I click on the icon of an application in focus, it gets minimized.
|
||||
|
||||
If you share the same preference, use this command in the terminal to [enable minimize on click in Ubuntu][26]:
|
||||
|
||||
```
|
||||
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'
|
||||
|
||||
```
|
||||
|
||||
#### 11\. Get familiar with the terminal
|
||||
|
||||
![][27]
|
||||
|
||||
Speaking of the terminal, please don’t be too scared of this awesome tool. I know that the command line gives cold feet to many new Linux users. However, knowing a little could help you big in long run.
|
||||
|
||||
I am not going to teach you the basics of the Linux command line here. Though I have written a pretty good post that tells you several [useful information on using the terminal in Ubuntu][28]. You should read the article even if you can use the terminal every now and then.
|
||||
|
||||
#### 12\. Few tweaks for laptop users
|
||||
|
||||
If you are using Ubuntu 22.04 on a laptop, here are a few tips on improving your performance and getting rid of annoyances.
|
||||
|
||||
You’ll notice that you have to press the left touchpad button for the left mouse button action. This is annoying. Enable the tap for click option and just tap the touchpad anywhere to get the left mouse click.
|
||||
|
||||
![][29]
|
||||
|
||||
From the Power settings, **enable the battery percentage display** to keep a track of the remaining battery on your laptop.
|
||||
|
||||
![][30]
|
||||
|
||||
Since you’ll be using your system on battery power, **choose an appropriate power profile** under the Power settings.
|
||||
|
||||
![][31]
|
||||
|
||||
This is perhaps not entirely for laptop users. By default, Ubuntu locks the screen after 5 minutes of inactivity and puts the system in suspend mode after 20 minutes of activity.
|
||||
|
||||
I don’t like entering my password so frequently. I **prefer to lock the screen at my convenience**. If you share the same feeling, you can also disable this behavior.
|
||||
|
||||
![][32]
|
||||
|
||||
#### 13\. Disable characters from GNOME search
|
||||
|
||||
The GNOME Search is an excellent tool for finding installed applications, files, etc. However, you’ll notice that it often shows matching ‘characters’.
|
||||
|
||||
![Emojis Desktop Search Ubuntu][33]
|
||||
|
||||
Actually, your Ubuntu system has built-in emoji support. Apart from the regular emoticons, the system also has support for letters in various languages like Thai, Latin, Vietnamese, etc.
|
||||
|
||||
When you search for something, the term could also match these special characters. Click on it and it gets copied to the clipboard and you can paste them wherever you want.
|
||||
|
||||
If you are not going to use this feature, you should disable the characters’ search.
|
||||
|
||||
![][34]
|
||||
|
||||
#### 14\. Use the night light feature to reduce eye strain at night
|
||||
|
||||
My favorite feature and I am glad it now works in the multi-monitor settings as well.
|
||||
|
||||
[Enable the night light feature][35] so that it adds a yellow tint to the screen which is less pinching than the white light at night.
|
||||
|
||||
Go to Settings -> Displays, switch to Night Light tab, and enable it. You can also set the ‘yellowness’ as per your liking.
|
||||
|
||||
![][36]
|
||||
|
||||
#### 15\. Enable fractional scaling if you’ve got a 4K screen
|
||||
|
||||
If you have a 2K or 4K screen, you’ll find that the icons, fonts and folders look too small. You should enable the fractional scaling and scale the size that suits your preference.
|
||||
|
||||
![][37]
|
||||
|
||||
#### 16\. Know that you have the option to go back to Xorg
|
||||
|
||||
Ubuntu 22.04 defaults to Wayland once again if you don’t have an Nvidia system. Wayland is the modern replacement of the legacy x server and it works very well with the newer GNOME components.
|
||||
|
||||
However, some older applications may not work properly under Wayland. For example, most screen recording tools don’t support Wayland yet.
|
||||
|
||||
If you encounter such a situation where a must-use application doesn’t work in Wayland, log out from the session and click on the gear icon in the bottom right to [switch to the X display session][38].
|
||||
|
||||
#### 17\. Classic GNOME is still available
|
||||
|
||||
Speaking of options, you can also access the classic GNOME. If you are not aware, the classic GNOME or GNOME version 2 was a popular desktop choice before GNOME 3 arrived with radical new changes around 2011.
|
||||
|
||||
GNOME 2 gave birth to the Cinnamon and MATE desktop environment because its die-hard users just didn’t want to give up on the classic interface. Perhaps that’s the reason why GNOME Classic has always been a part of Ubuntu even though it moved to Unity and (modern) GNOME.
|
||||
|
||||
Though it says classic, it doesn’t look as dated as it was in 2010.
|
||||
|
||||
![GNOME Classic][39]
|
||||
|
||||
When you log out of the system, click on the user name and you should see a gear symbol at the bottom. Click on it and you should see the classic GNOME option here.
|
||||
|
||||
#### 18\. Know about cleaning your system
|
||||
|
||||
The classic apt autoremove command is a good way to remove packages that are not required anymore.
|
||||
|
||||
```
|
||||
|
||||
sudo apt autoremove
|
||||
|
||||
```
|
||||
|
||||
I think it is also part of the software updater tool now meaning it runs the autoremove command after running updates or so I have noticed.
|
||||
|
||||
Apart from that, there are a [few more ways to clean up your Ubuntu system][40]. GUI tools like Stacer are now available in the repositories and you may use them to clean your system without going into the command line.
|
||||
|
||||
#### 19\. Master the keyboard shortcuts
|
||||
|
||||
I am not asking you to ditch the mouse altogether but trust me on this using the keyboard shortcut saves plenty of time.
|
||||
|
||||
From the application switcher to opening the terminal, things feel a lot faster with the correct shortcuts at your finger.
|
||||
|
||||
![keyboard switching with key shortcut in Ubuntu][41]
|
||||
|
||||
I have an entire article dedicated to [keyboard shortcuts in Ubuntu][42]. Feel free to check that out.
|
||||
|
||||
#### 20\. Use the ‘do not disturb mode to focus on work
|
||||
|
||||
There are plenty of productivity tools available for Ubuntu but this little hack is my favorite.
|
||||
|
||||
When I am working on something that requires my complete focus, like writing this article, I enable the Do Not Disturb mode.
|
||||
|
||||
![][43]
|
||||
|
||||
With that, the notifications from messaging services stop appearing on the screen and I don’t get distracted. Once I am back to relaxed working, I disable it again.
|
||||
|
||||
#### 21\. Get back the original Firefox or go for some other browser
|
||||
|
||||
Ubuntu 22.04 Jammy Jellyfish comes with the Snap version of Firefox. It takes longer to start and forces you to log in to the accounts again and again.
|
||||
|
||||
Try the Snap version of Firefox first. If it works for you, good. If not and you feel fed up with the Firefox experience, you have two options:
|
||||
|
||||
* Switch to another browser like Brave, Vivaldi, LibreWolf, etc
|
||||
* Switch to Firefox ESR or a non-Snap version of Firefox
|
||||
|
||||
|
||||
|
||||
Firefox ESR (extended support release) doesn’t come with the latest feature like the regular Firefox but it is maintained for security and stability fixes.
|
||||
|
||||
There are a couple of ways of [getting the non-Snap version of Firefox][44] as described by Jim at Ubuntu Handbook. However, it is slightly more complicated than just adding a PPA.
|
||||
|
||||
#### 22\. Get missing Windows back if you use a dual boot system
|
||||
|
||||
During the early testing of Ubuntu 22.04, I noticed a known bug that came with the new Grub 2.6. It had disabled the os-prober by default. This means that Grub won’t check for the presence of other operating systems. In other words, it won’t see Windows (or other Linux distributions) if you opted for a dual boot system.
|
||||
|
||||
Now, I haven’t checked if this issue has been fixed or not but if you face this issue with your dual boot system, then edit the /etc/default/grub file to add GRUB_DISABLE_OS_PROBER=false to this file. Save this file, [update grub][45] and Grub should see other operating systems now.
|
||||
|
||||
#### Where to go from here?
|
||||
|
||||
![][46]
|
||||
|
||||
Honestly, you could do a lot more even after you have done all the points I mentioned in this list here. There is no end to things you could do after installing Ubuntu 22.04.
|
||||
|
||||
If you are new, there is plenty to explore. If you are an experienced one, you could still spend considerable time tweaking and setting up your system as per your liking.
|
||||
|
||||
It all comes down to personal preference. Some people would just do some basic changes and go on with using the operating system. Some folks would spend hours setting everything to perfection.
|
||||
|
||||
Now that I have finished my recommendations, I would like your views. Did you find some useful tips here? What other usual stuff do you do after installing Ubuntu?

How to Upgrade to Pop OS 22.04 LTS from 21.10 [Step by Step]
|
||||
======
|
||||
WE GIVE YOU EASY STEPS TO UPGRADE TO POP OS 22.04 LTS FROM POP OS 21.10.
|
||||
System76 [released][1] the Pop OS 22.04 LTS following [Ubuntu 22.04 LTS][2], which brings some exciting features. Pop OS 22.04 LTS is a long-term support release from System76 that brings automatic scheduling updates, customised GNOME 42, underlying performance improvements, and [many other features][3].
|
||||
|
||||
You must be excited to experience Pop OS 22.04 and planning to upgrade. Here we give you the steps to upgrade to Pop OS 22.04 LTS.
|
||||
|
||||
: You can not upgrade from Pop OS 20.04 to Pop OS 22.04. First, you need to upgrade to Pop OS 21.10 and follow the steps outlined here to upgrade to this release.
|
||||
|
||||
### Upgrade to Pop OS 22.04 from Pop OS 21.10
|
||||
|
||||
#### Before Upgrade
|
||||
|
||||
Pop OS upgrade process is relatively stable. Because as per our [last article on updates][4], many users faced upgrade issues. But if you are running Pop OS with NVIDIA hardware, I recommend you take backups.
|
||||
|
||||
* Make sure your system is up to date. You can use the Pop Shop application and check for updates. Alternatively, you can open a terminal prompt and run the following for upgrades.
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
sudo apt update && sudo apt upgrade
|
||||
|
||||
```
|
||||
|
||||
* After the update is complete with the above steps, reboot your system.
|
||||
* Take backups to your documents, photos, videos or any document to separate disk partition or in a USB drive.
|
||||
* Disable all GNOME extensions before upgrading. Many extensions are in the process of migrating to GNOME 42. Hence, it would be best if you disabled all of them before upgrading and later enabled them.
|
||||
* Note down all the external software sources or PPA you may have added because they may not be compatible with the “jammy” branch. You may need to verify them after the upgrade.
|
||||
* Close all the running applications.
|
||||
* Finally, make sure you have some time in hand and a stable internet connection for the upgrade to finish.
|
||||

|
||||
|
||||
### Upgrade Steps for Pop OS 22.04 LTS
|
||||
|
||||
#### GUI Method
|
||||
|
||||
If you are running Pop OS 21.10, you should see a prompt like the below if your system is updated.
|
||||
|
||||
![Pop OS 22.04 Upgrade Prompt][6]
|
||||
|
||||
Alternatively, you can open Settings and visit OS Upgrade and Recovery tab. Here you should see that update is available.
|
||||
|
||||
![Pop OS 22.04 Upgrade Prompt in Settings][7]
|
||||
|
||||
Click Download to start the upgrade process.
|
||||
|
||||
#### Terminal Method to Upgrade to Pop OS 22.04 LTS
|
||||
|
||||
* Open a terminal and run the following commands.
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
sudo apt update
|
||||
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
sudo apt full-upgrade
|
||||
|
||||
```
|
||||
|
||||
* This ensures your system is up-to-date before the upgrade process begins. You may ignore this step if you have already completed this as part of the pre-upgrade steps described above.
|
||||
|
||||
|
||||
* Update the recovery partition using the below command and wait for it to be finished. This is only applicable for UEFI installs.
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
pop-upgrade recovery upgrade from-release
|
||||
|
||||
```
|
||||
|
||||
* Now start the upgrade process using the following:
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
pop-upgrade release upgrade
|
||||
|
||||
```
|
||||
|
||||
![Start the upgrade process][8]
|
||||
|
||||
* Firstly, the upgrade will start the download of the packages. As of our test, around 1600+ packages need downloading. Hence you should wait until it finishes.
|
||||
|
||||
|
||||
* Secondly, once the download is complete, the upgrader will prompt you for the reboot.
|
||||
|
||||
|
||||
|
||||
![Ready for upgrade][9]
|
||||
|
||||
* Pop OS would start installing the latest packages to your system after the reboot.
|
||||
|
||||
|
||||
* Finally, the download process takes about an hour, so wait for it to be finished. I would not recommend stopping the upgrade mid-way as it may lead to an unstable system.
|
||||
|
||||
|
||||
|
||||
![Pop OS 22.04 LTS Desktop][10]
|
||||
|
||||
* After the upgrade is complete, enjoy the brand new Pop OS 22.04 LTS.

5 Best Mastodon Clients for Ubuntu and Other Linux
|
||||
======
|
||||
ARE YOU PLANNING TO LEAVE TWITTER AND JOIN MASTODON? USE THESE FREE AND
|
||||
OPEN-SOURCE MASTODON CLIENTS FOR YOUR LINUX DESKTOP.
|
||||
[Mastodon][1] is a free and open-source microblogging platform similar to Twitter. It is designed as a decentralised platform that can communicate with other Fediverse protocols such as GNU Social and Pleroma. With the recent news stories about Twitter, many users are trying Mastodon and migrating to the platform.
|
||||
|
||||
With that in mind, we give you a list of free Mastodon clients for Linux desktops as well as Windows and macOS in this post.
|
||||
|
||||
### Top 5 Mastodon Clients for Ubuntu and Other Linux Distributions
|
||||
|
||||
#### 1\. Tootle
|
||||
|
||||
Perhaps the best on this list is the GNOME App Tootle. Tootle is a super-fast Mastodon client for Linux desktops written in GTK. It comes with a clean and native interface that you can use while using Mastodon. With this app, you can easily browse posts, view feeds, have a customised home page and follow accounts. In addition to that, dedicated tabs gives you options to quickly jump between your home page, notifications, mentions and federated feed.
|
||||
|
||||
Tootle is actively developed, and it is an official GNOME Circle app. And we featured it in our [GNOME Apps series (#5)][2].
|
||||
|
||||

|
||||
|
||||
The easiest way to install Tootle is using Flatpak in any Linux distribution. Setup your system using this [guide for Flatpa][4]k (if not done yet) and hit the below link to install.

||||
#### 2\. Tokodon
|
||||
|
||||
The Tokodon is another Mastodon client which brings a little different user interface to access this social platform. Its part of KDE Applications and built primarily using C++. It gives you an excellent clean user interface with a basic home page view. On top of that, you can browse local accounts to your mastodon server and the global ones. The bottom navigation gives easy access to all the Mastodon sections.

|
||||
#### 3\. Sengi
|
||||
|
||||
Among this list, Sengi is most likely the versatile Mastodon client for Linux desktops. It comes with usual features such as notification, account view and follows features. On top of that, it brings Tweetdeck styled live interface with the timeline.
|
||||
|
||||
Sengi is perfect for heavy Mastodon users who want to manage multiple accounts and timelines. You can even set up and Twitter bridge as well.
|
||||
|
||||
Furthermore, you should note that it is designed with web technology and packaged as desktop applications. Finally, it is available for Linux, macOS and Windows as well.
|
||||
|
||||

|
||||
|
||||
Finally, installing Sengi is very easy because the developer provides all types of executables, including native deb and AppImage. You can grab the .deb or .appimage file from the below link in addition to the windows and Mac executables.

|
||||
#### 4\. Whalebird
|
||||
|
||||
Whalebird is another free and open-source Mastodon client built using Electron. Moreover, this web-based application is feature-rich and is the most stable Mastodon client. Using Whalebird, you can manage multiple accounts and monitor multiple timelines. In addition to that, you can also create a custom timeline to follow your favourite hashtags with a simple chronological workspace view.
|
||||
|
||||
![Whalebird Mastodon Client | Image Credit: Whalebird][16]
|
||||
|
||||
Finally, installing Whalebird is easy because it comes with an AppImage executable for Linux. Also, it provides the exe and dmg file for other OSes, which you can grab using the below link.

||||
|
||||
|
||||
|
||||
#### 5\. TheDesk
|
||||
|
||||
The fifth Mastodon client for Linux and other OSes we would like to feature is TheDesk. It is perhaps the most feature-rich client with a vast list of features. Its workflow is similar to Hootsuite and Tweetdeck for heavy social media monitoring and usage. You can customise it to follow a particular user, hashtags with options to create multiple timeline views.
|
||||
|
||||
But it might not be a stable client and may contain bugs. But you can still try it out.
|
||||
|
||||
Installing is made easy by its developer with app image, deb, snap and exe files available on GitHub for its releases. You can grab them here.

### Other Options to access Mastodon
|
||||
|
||||
#### Mastodon Web
|
||||
|
||||

Bloomberg Open Sources Memray, A Python Memory Profiler
|
||||
======
|
||||
![soft][1]
|
||||
|
||||
Memray is a memory profiler that was developed at Bloomberg and is now open source. It can track memory allocations in Python code, including native extensions and the Python interpreter itself. Memory profiling is a strong tool for understanding how a program utilises memory and, as a result, detecting memory leaks or determining which areas of the program consume the most memory.
|
||||
|
||||
In contrast to sampling memory profilers like py-spy, Memray can track every function call, including calls into C/C++ libraries, and display the call stack in detail. Bloomberg claims that this does not come at the sacrifice of performance, with profiling only slowing down interpreted code by a little amount. However, native code profiling is slower and must be enabled directly.
|
||||
|
||||
Memray may generate a variety of reports based on the acquired memory consumption data, including flame graphs, which are valuable for rapidly and precisely identifying the most common code-paths.
|
||||
|
||||
According to Yury Selivanov, co-founder and CEO of EgdeDB, the tool gives previously unavailable insights into Python applications. Memray can be used to execute and profile a Python application from the command line:
|
||||
|
||||
```python
|
||||
$ python3 -m memray run -o output.bin my_script.py
|
||||
$ python3 -m memray flamegraph output.bin
|
||||
```
|
||||
|
||||
Alternatively, you can use pytest-memray to integrate Memray into your test suite. You can also profile all C/C++ calls with the —native command line option, or analyse memory allocation in real time while a programme is executing with the —live command line option. Memray can be installed with python3 -m pip install memray on a Linux x86/64 system.

Hands on With GNOME’s New Text Editor for Linux Users
|
||||
======
|
||||
|
||||
If you are a regular reader here on It’s FOSS, you might have read about [GNOME’s plan to replace Gedit with their own text editor][1].
|
||||
|
||||
Yes, GNOME has a brand-new text editor and it is called, well, Text Editor.
|
||||
|
||||
While Gedit is still the default, this new editor has made an entry with the release of GNOME 42. I am using Ubuntu 22.04 and it is available to install from the repositories.
|
||||
|
||||
Not exactly a brand-new [feature of Ubuntu 22.04][2], this new editor is available to install in the latest Ubuntu LTS version and perhaps other distributions using GNOME 42.
|
||||
|
||||
Intrigued? Let me share my experience with this new editor and then I’ll show you the installation steps.
|
||||
|
||||
### Experience with GNOME Text Editor
|
||||
|
||||
Built on top of the [controversial libadwaita][3], GNOME Text Editor follows the new design principles set by its development committee. It has a sleek, modern look with rounded corners.
|
||||
|
||||
Don’t expect anything extraordinary here in terms of features. It’s not a replacement of coding focused editors like [Atom or VS Code][4]. This also doesn’t mean it’s as plain and simple as Windows’ Notepad.
|
||||
|
||||
Let’s see what it has to offer.
|
||||
|
||||
#### Saved sessions
|
||||
|
||||
By default, GNOME Text Editor automatically opens the last opened files. This is a neat feature that lets you resume your work.
|
||||
|
||||
This behavior can be controlled by the Restore Session option under Preferences.
|
||||
|
||||
![][5]
|
||||
|
||||
You can also search and open the recently opened files. Clearing the history (as shown in the above image) will clear the recently accessed files.
|
||||
|
||||
#### Themes and in-built themes
|
||||
|
||||
Like new GNOME applications, it gives you three theming style to choose from: system theme, light theme and dark theme. If you have chosen system theme, the editor will automatically switch between light and dark theme based on the system theme (light or dark) in use.
|
||||
|
||||
![System theme option gnome text editor][6]
|
||||
|
||||
Apart from that, you can choose between eight available themes (available in dark and light variants) under the preference section.
|
||||
|
||||
![Theme options under preference][7]
|
||||
|
||||
You can see the changes immediately as you select the themes.
|
||||
|
||||
#### Changes and Unsaved file handling
|
||||
|
||||
Modified and unsaved files are prominently reflected while you work on them.
|
||||
|
||||
![Unsaved files are more prominently marked][8]
|
||||
|
||||
You’ll obviously be warned if you try to close the editor with modified files.
|
||||
|
||||
![][9]
|
||||
|
||||
There is no automatic save options here. [Gedit has option for automatically saving files][10] without using any additional plugins.
|
||||
|
||||
#### No plugins
|
||||
|
||||
Speaking of plugins, there is no such system for the new text Editor yet. Gedit has a decent plugin ecosystems that helps in enhancing the capacity of the editor.
|
||||
|
||||
I don’t have any concrete information if plugins will be allowed in this editor in the future or not.
|
||||
|
||||
#### Syntax highlighting
|
||||
|
||||
Syntax highlight is an integral part of text editors these days. GNOME Text Editor promptly highlights syntax for various programming language.
|
||||
|
||||
This is usually done based on the extension of the code file. However, I noticed that it also detects and highlights syntax for bash scripts and C/C++ programs even before saving the file.
|
||||
|
||||
![Bash scripts. C/C++ code are detected even without file extension][11]
|
||||
|
||||
#### Keyboard shortcuts
|
||||
|
||||
I love using keyboard shortcuts in my favorite applications. It makes things quicker.
|
||||
|
||||
The GNOME Text Editor supports plenty of keyboard shortcuts for all kind of actions. You can find the list of keyboard shortcuts under the hamburger menu (☰) or use the keyboard shortcut Ctrl+?.
|
||||
|
||||
![Keyboard shortcuts in GNOME Text Editor][12]
|
||||
|
||||
#### Search and replace
|
||||
|
||||
Text Editor has pretty decent find and replace feature. You can use set extra parameters like regex search, case-sensitive search or match exact words.
|
||||
|
||||
![search replace gnome text editor][13]
|
||||
|
||||
#### More features
|
||||
|
||||
There are several other features that you may find in Gedit:
|
||||
|
||||
* Spell check
|
||||
* Line numbers
|
||||
* Automatic indentation
|
||||
* Space/tab indentation
|
||||
* Change case
|
||||
* Text wrapping
|
||||
|
||||
|
||||
|
||||
#### What it doesn’t do?
|
||||
|
||||
It is essentially a text editor, so you cannot open doc files in it and that’s by design. If you open a doc file, you’ll see gibberish. The same goes for PDF files.
|
||||
|
||||
![][14]
|
||||
|
||||
Also, it is not intended for hardcore coding. It cannot replace the likes of VS Code. It is okay for occasional code reading or shell scripting but it doesn’t have the features like project folders or running the codes.
|
||||
|
||||
### Installing GNOME Text Editor
|
||||
|
||||
As stated earlier, it is available with GNOME 42, but not installed by default. In Ubuntu 22.04, it is available in the Universe repository and can be installed with the following command:
|
||||
|
||||
```
|
||||
|
||||
sudo apt install gnome-text-editor
|
||||
|
||||
```
|
||||
|
||||
It should be available in other distros with GNOME 42. Please [check the version of desktop environment][15] you are using.
|
||||
|
||||
Once installed, you can search and open it in the Activities area. The icon for the new editor is a refreshed version of the Gedit icon.
|
||||
|
||||
![][16]
|
||||
|
||||
### Conclusion
|
||||
|
||||
The good old [Gedit][17] has been a part of GNOME for a long time. There were lack of development a few years ago but the development has resumed again. However, the GNOME team is working on revamping their core applications for GTK 4 and libadwaita.
|
||||
|
||||
This new Text Editor looks like a reimplementation of the Gedit with similar interface and feature but a more fluid experience which is more consistent with the new GNOME design.
|
||||
|
||||
It won’t surprise me that this new editor becomes the default text editor in the coming version of GNOME. It would be interesting to see if a plugin ecosystem is developed for the new editor or not.

Updating Edge Devices with OSTree and Pulp

Connecting industrial machinery to the internet has given birth to infinite opportunities that range from performance improvements and predictive maintenance to data modelling that can lead to novel solutions and use cases. The possibilities are endless. Connecting machinery on such a scale can test the limits of cloud connectivity, depending on your location and network limitations.
|
||||
|
||||
An edge device is any piece of hardware that sits at the boundary between two networks. When initial computation happens on servers at the edge, it speeds up user’s interactions with the cloud. Therefore, adding edge devices provides opportunities to optimize performance, shorten the journey, and lighten the load on your cloud connection.
|
||||
|
||||
As amazing as it sounds, managing all of this functionality demands continuous attention from administrators. Having a reliable solution to distribute, deploy, and update systems for edge devices from the outset will help you spend time on things that matter.
|
||||
|
||||
In this article, we look at how OSTree is well-positioned for upgrading and updating edge devices with versioned updates of Linux-based operating systems. Furthermore, we’ll explore how Pulp facilitates managing and preparing updates of the OSTree content, as well as making it available to edge devices. Together, they provide a powerful free and open-source solution for administering edge devices.
|
||||

### How does OSTree help manage Edge devices?
|
||||
|
||||
If you need to deploy hundreds of operating systems to edge devices, safe in the knowledge that you can easily manage future updates and maintenance, an OSTree’s immutable and image-based operating system is ready for the task.
|
||||
|
||||
[OSTree][4] functions like git, but for operating system binaries. It has git-like content-addressed repositories. The ability to commit and branch entire root filesystem trees resembles the way you submit changes in git. With OSTree, you build an operating system with pre-installed packages, known as an operating system image. After you build the operating system image, it is possible to track it, sign it, test it, and deploy it. These images function as immutable file system trees. When the time comes to change or update, you simply build a new image and deploy it. By atomically switching between different versions of images, you are completely replacing filesystem trees.
|
||||
|
||||
OSTree also has a simple CLI that you can use for managing simple workflows, for example, for switching between different versions of images/filesystem trees.
|
||||
|
||||
### Where do Fedora-IoT Images feature?
|
||||
|
||||
As a standalone tool, the base OSTree CLI is not the most feature-rich utility for managing repository content. To make life easier, in the following demo, we will use _[rpm-ostree][5]_. _rpm-ostree_ is a hybrid image/package system that combines the standard OSTree technology as a base image format and accepts RPM on both the client and server-side.
|
||||
|
||||
_rpm-ostree_ integrates with Fedora IoT. In comparison to other ecosystems, instead of installing packages via DNF, you install packages with _rpm-ostree_. After rebooting all changes are applied to a new version of the image.
|
||||
|
||||
You can also upgrade or install a new Fedora IoT image with the _rpm-ostree_ utility.
|
||||
|
||||
### Where and how does Pulp come into this?
|
||||
|
||||
[Pulp][6] is a platform that handles content management workflows. Using Pulp, you can sync packages from remote repositories such as an RPM server, PyPI, Docker Hub, Ansible Galaxy, and many more. You can host and modify synced packages in repositories inside the Pulp server. You can publish repositories that contain packages available for deployment to production environments.
|
||||
|
||||
In our scenario, Pulp provides a platform for storing particular versions of OSTree content, promoting approved content through the content management lifecycle, for example from _dev_ to _test_, and from _test_ to _prod_. Pulp also provides a method for publishing content that is consumed by edge devices. Using Pulp, you can pull the latest packages, test, and publish only when safe to do so. Pulp ensures the safety, security, and repeatability of your content supply chain.
|
||||
|
||||
The following diagram provides a simplified overview of Pulp. On the left are shown different content types that are mirrored into Pulp from remote sources. These repositories are then served, for instance, to different CI/CD or production environments.
|
||||
|
||||
![A simplified overview of Pulp. The content is mirrored from remote repositories and made available to different types of environments.][7]
|
||||
|
||||
Pulp creates a new repository version automatically when updating or removing packages in a repository. You can distribute each repository version independently.
|
||||
|
||||
Pulp has a plugin-based architecture, which means that you must add a plugin for each content type you want to use. For managing OSTree content, you need [the OSTree plugin][8]. You can then mirror content from a remote repository, import content from a local tarball, and modify content within a Pulp repository while preserving the integrity of the original content. You can move commits and refs from one repository to another or delete them. Pulp ensures that you are safe to experiment while your production environment remains pinned to a particular version.
|
||||
|
||||
### Putting it all together
|
||||
|
||||
In this section, let’s look at how to build an image with an OSTree commit.
|
||||
|
||||
#### Building a Customized Fedora-IoT Image
|
||||
|
||||
We start by booting a new virtual machine (VM) that will have an installed Fedora-IoT OS. For the purposes of this example, it is best to have the same version of the OS installed as the running edge devices have.
|
||||
|
||||
All commands in this section are executed on the main admin VM (Fedora IoT 35 OS). On this admin VM, we will build the images that we will then distribute to the edge devices.
|
||||
|
||||
##### Before you begin:
|
||||
|
||||
* First, ensure that the VM is accessible via SSH. To test, enter the following command from within the target OS:
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
$ systemctl is-active sshd
|
||||
|
||||
```
|
||||
|
||||
* Next, ensure that the following tools for composing operating system images are installed:
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
$ sudo rpm-ostree install osbuild-composer composer-cli
|
||||
$ sudo systemctl enable --now osbuild-composer.socket
|
||||
|
||||
```
|
||||
|
||||
* Now, apply the installed packages by rebooting the system.
|
||||
|
||||
|
||||
|
||||
* * *
|
||||
|
||||
In this example a nano editor package is installed on all edge devices. We need to build an image containing a commit with the package.
|
||||
|
||||
Create a blueprint file that describes what changes you want to make to the image as shown here:
|
||||
|
||||
```
|
||||
|
||||
$ cat install-nano.toml
|
||||
|
||||
name = "nano-commit"
|
||||
description = "Installing nano"
|
||||
version = "0.0.1"
|
||||
|
||||
[[packages]]
|
||||
name = "nano"
|
||||
version = "*"
|
||||
|
||||
```
|
||||
|
||||
Push this blueprint to the os build composer utility, which is a tool for composing operating system images. _composer-cli_ communicates with _osbuild composer_ through the CLI:
|
||||
|
||||
```
|
||||
|
||||
$ composer-cli blueprints push install-nano.toml
|
||||
|
||||
```
|
||||
|
||||
Build a new image:
|
||||
|
||||
```
|
||||
|
||||
$ composer-cli compose start-ostree nano-commit fedora-iot-commit --ref fedora/stable/x86_64/iot
|
||||
|
||||
```
|
||||
|
||||
The composer will use resources available in your current OS (such as a default operating system version).
|
||||
|
||||
Regularly check the status of the build:
|
||||
|
||||
```
|
||||
|
||||
$ composer-cli compose status
|
||||
|
||||
```
|
||||
|
||||
When the build finishes, download the image:
|
||||
|
||||
```
|
||||
|
||||
$ composer-cli compose image ${IMAGE_UUID}
|
||||
|
||||
```
|
||||
|
||||
The downloaded image is basically an OSTree repository packed into a tarball. When you extract the archived content, you will notice that one ref is referencing the checksum of a commit. You can find it inside the _refs/heads/_ directory.
|
||||
|
||||
#### Publishing the Customized Image with Pulp
|
||||
|
||||
All commands shown in this section are executed on the main admin VM (Fedora IoT 35 OS).
|
||||
|
||||
##### Before you begin:
|
||||
|
||||
* Ensure that you have installed Pulp and the Pulp CLI for managing OSTree repositories:
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
$ python3 -m venv venv && source venv/bin/activate
|
||||
$ pip install pulp-cli-ostree
|
||||
|
||||
```
|
||||
|
||||
* Then [configure][9] the reference to the Pulp server:
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
$ pulp config create && pulp status
|
||||
|
||||
```
|
||||
|
||||
Now configure a proxy server or SSH port forwarding to enable network communication between the VM and Pulp. Ensure that you can ping the Pulp server from the VM.
|
||||
|
||||
* * *
|
||||
|
||||
First, create a new OSTree repository:
|
||||
|
||||
```
|
||||
|
||||
$ pulp ostree repository create --name fedora-iot
|
||||
|
||||
```
|
||||
|
||||
The following command will import the tarball created in the previous section into Pulp:
|
||||
|
||||
```
|
||||
|
||||
$ pulp ostree repository import-commits --name fedora-iot --file ${IMAGE_TARBALL_C1} --repository_name repo
|
||||
|
||||
```
|
||||
|
||||
Publish the parsed commit as a remote OSTree repository hosted by Pulp:
|
||||
|
||||
```
|
||||
|
||||
$ pulp ostree distribution create --name fedora-iot --base-path fedora-iot --repository fedora-iot
|
||||
|
||||
```
|
||||
|
||||
Try to fetch the commit checksum from the ref:
|
||||
|
||||
```
|
||||
|
||||
$ curl http://${PULP_BASE_ADDR}/pulp/content/pulp-fedora-iot/refs/heads/fedora/stable/x86_64/iot
|
||||
|
||||
```
|
||||
|
||||
#### **Distributing the Customized Image to an Edge Device**
|
||||
|
||||
The Edge device can be another VM or a real device running Fedora IoT.
|
||||
|
||||
All commands shown in this section are executed on an Edge device (Fedora IoT 35 OS).
|
||||
|
||||
##### Before you begin:
|
||||
|
||||
* Configure a proxy server or SSH port forwarding to enable network communication between an Edge device and Pulp. Ensure that you can ping the Pulp server from the Edge device.
|
||||
* Ensure that the Edge device is accessible with SSH:
|
||||
|
||||
|
||||
|
||||
```
|
||||
|
||||
$ systemctl is-active sshd
|
||||
|
||||
```
|
||||
|
||||
* * *
|
||||
|
||||
The nano package should NOT come pre-installed with the official bare Fedora IoT 35 image. Verify that by attempting to run _nano_ inside your terminal.
|
||||
|
||||
In Fedora IoT, updates are retrieved from the URL defined in **/etc/ostree/remotes.d/fedora-iot.conf**. This file can be modified manually or by adding a new remote repository. Learn more at [Adding and Removing Remote Repositories][10].
|
||||
|
||||
You can automate the upgrade procedure with an upgrade policy that will be configured at the beginning of deployment. This is done by writing a kickstart file that will boot up an edge device into a headless state. However, for demonstrative purposes, let’s act like a villain and update the aforementioned configuration file manually to have the following content:
|
||||
|
||||
```
|
||||
|
||||
[remote "fedora-iot"]
|
||||
url=http://${PULP_BASE_ADDR}/pulp/content/pulp-fedora-iot/refs/heads/fedora/stable/x86_64/iot
|
||||
gpg-verify=false
|
||||
ref=fedora/stable/x86_64/iot
|
||||
|
||||
```
|
||||
|
||||
Do not forget to replace the variable _${PULP_BASE_ADDR}_ with a valid base path to the pulp server.
|
||||
|
||||
The following command shows you that some packages are going to be installed:
|
||||
|
||||
```
|
||||
|
||||
$ rpm-ostree upgrade
|
||||
|
||||
```
|
||||
|
||||
Reboot the edge device:
|
||||
|
||||
```
|
||||
|
||||
$ systemctl reboot
|
||||
|
||||
```
|
||||
|
||||
_…rebooting…_
|
||||
|
||||
Log in to the edge VM via ssh, and check the presence of the nano package that comes from Pulp:
|
||||
|
||||
```
|
||||
|
||||
$ nano
|
||||
|
||||
```
|
||||
|
||||
**Done! You have successfully distributed a customized Fedora IoT image via Pulp!**

如何把开源作为一份职业
|
||||
======
|
||||
你是否对开源充满热情，却不知道如何在这个领域开始一段职业生涯？那么，这篇文章就是为你准备的。
|
||||
|
||||
![目标-成就-团队-业务-概念][1]
|
||||
|
||||
你知道吗？80% 的维护者认为招募新的贡献者是一个挑战，92% 的雇主认为很难雇用到开源人才。而另一方面，52% 的开发者希望为开源做出贡献，33% 的人不知道从哪里开始，31% 的人认为自己不够熟练。公共数据显示，社会对具有开源技能的人有很大的需求。因此，让我们看看如何才能够把开源作为一份职业，以填补这个供需之间的差距吧！
|
||||
|
||||
### 掌握一个技能
|
||||
|
||||
开源旅程的起点仅仅是你擅长的某个技能罢了。许多开发者会在空闲时间从事开源工作，他们投入精力到自己非专业的技能上，并把这些技能引入到技术领域里来。像机器学习（ML）、云原生和大数据分析这样的技能是很受欢迎的，因为许多项目都围绕着它们而进行。
|
||||
|
||||
开发者必须不断尝试，直到找到自己感兴趣的东西为止。例如，当我开始在开源领域工作时，我选择了移动用户界面（UI）和 Web 开发（包括前端和后端）方面的工作。这个选择并不简单，我花了很多时间来弄清楚我想从事什么。因此，重要的是要遵循你的兴趣，通过学习和建立项目来探索不同的领域。很多时候，理论教程可能不如建立实际项目更有帮助。掌握技能的唯一方法是将所学的东西应用到实际项目中。
|
||||
|
||||
如果你已经在某项技术和项目上投入了很长时间，那么你应该花时间好好分析一下。如果你对这个项目不感兴趣，那么放弃它可能是更好的选择。然而，这也可能是一把双刃剑。有可能你会发现一些感兴趣的东西，从而产生一个新的权衡。如果经过了充分的分析，你也知道了自己倾向于哪些技能组合，那么下一步就是建立自己的项目。
|
||||
|
||||
### 建立一个项目
|
||||
|
||||
无论项目的内容如何，只要它是活跃的，就会产生很大的价值。但请记住，一旦它开源了，你千万不要被大家的反应所左右。并且记住，无论你是为一个应用程序建立一个 UI，还是仅仅记录一个适当的注释、资源或 URL 的列表，你的工作都可以对开源用户有很大帮助。
|
||||
|
||||
在很大程度上，学习不同的工具有助于建立开源项目。因此，学习关于版本控制系统、Git、GitHub 和 GitLab（大多数项目都在它们上面）的一切是很重要的。由于互联网上已经有足够的教程，我只收集了一些可以在 *navendu.me/osidays.* 上找到的。你需要通过撰写文档和公开自己学到的内容，来“公开学习”才行。
|
||||
|
||||
### 打造一份职业
|
||||
|
||||
你可以通过三种方式在开源领域建立一个职业。
|
||||
|
||||
#### 构建、扩展你自己的开源项目，并让它盈利
|
||||
|
||||
如果你想要建立一个自己的项目，发现并解决问题是一个很好的经验法则。记下别人可能面临的问题，一个项目需求就这样产生了。你的项目的市场规模只能通过试验和错误来估计。对于既没有太多资金的、也没有太多经验个人贡献者来说，社交媒体、博客、帖子和会议上的谈话，都会在很大程度上有助于接触到用户。这些平台可以为你的开源项目带来巨大的流量。
|
||||
|
||||
资金在几乎所有的商业模式中都起着重要作用。Mozilla 基金会依靠自愿捐款来资助其项目。MariaDB 采用了延迟开放源代码的商业模式。IBM 的许多开源项目遵循开放核心的商业模式，即项目的核心部分是开源的，而周围的附加部分是闭源的和专有的。红帽公司不出售代码，而是出售专业服务，如支持、工具和围绕项目的技术援助。这些商业模式的例子可以被采用，以此来建立一个项目，将它开源，并使其盈利。
|
||||
|
||||
#### 在一个以开源商业模式建立项目的公司工作
|
||||
|
||||
作为贡献者和维护者社区的一份子，参与会谈和参加会议将有助于你为项目做出贡献。你可以根据引导来完成第一次贡献，但它不一定得是代码。一个大的代码库可能看起来很吓人，但关键是要从小的地方着手。找到一个问题并解决它，这将有助于你了解贡献流程、代码库和项目设置等。
|
||||
|
||||
非代码的贡献也是有价值的。擅长写作的人可以通过撰写文档，或者为社交媒体写作来贡献。擅长设计的人，可以设计一个惯例，一个颜色方案，或者也可以致力于创造一个更好的用户界面。与高级工程师相比，新人发现错误的概率很高。他们可以测试、确认并报告他们的用户体验，从而提升项目质量。另一个领域是新手引导，很多开源项目将导师和新手联系起来，并帮助后者做出重要贡献。还有一个选择是成为组织者或社区管理员，这意味着你将承担起项目经理的角色，确保功能完全按照预期交付，路线图被遵循，贡献者得到照顾。大多数开源项目缺乏适当的管理，因为工程师们都不喜欢做这一类工作。
|
||||
|
||||
社会上有很多实习项目可以帮助你赚钱，比如谷歌的编程之夏（GSoC）和 Linux 基金会的导师制（在这里，被指导者有津贴，可以根据需要全职或兼职工作）。如果你能很好地发展你的技能，你可以在你实习的公司获得一个全职的职位。例如，如果你在红帽公司的一个项目中工作，你有机会被全职雇用，因为你在那里已经有了知名度。
|
||||
|
||||
正如 NumPy、SciPy 和 Anaconda 的作者 Travis Oliphant 所说，“建立一个开源项目，让人们为它做出贡献，然后从他们当中招聘。” —— 这也是我获得全职工作的方式。
|
||||
|
||||
* 随着时间的推移，你所做贡献的质量和数量会不断提升。最好长期参与一个项目，因为这样可以发现更多的贡献领域。投身进去做贡献会让人们注意到并认可你。
|
||||
* 开源项目缺乏项目经理，因此成为项目经理将有助于你的职业生涯。
|
||||
* 成为一个维护者，做一些工程师应该做的事情，如审阅代码、设计系统、撰写文档和帮助他人做出贡献。
|
||||
* 好的贡献的关键是“提前付出”，这意味着你需要通过分享经验和智慧来帮助新人，并确保他们不犯错误。
|
||||
|
||||
#### 获得赞助以从事开源工作
|
||||
|
||||
作为个人，如果你正在为某个公司建立的项目而工作，你可以要求获得资助。值得注意的是，只有当你的贡献很大时，组织才会乐意赞助你。但是，如果你建立了自己的项目，并且有大量的用户群，你可以向用户要求资助。
|
||||
|
||||
作为一个组织，你可以通过像 Open Collective、Patreon 和 GitHub Sponsors 这样的平台来筹集资金，让人们为你的项目捐款。像 Linux 基金会和 Mozilla 基金会这样的开源巨头也提供资金来支持项目。GitHub 已经给 15 个印度贡献者的项目提供了资助。
|
||||
|
||||
我曾经花了三个月时间建立了一个开源项目。这个项目后来被 Product Hunt 和 JS 周刊报道，还在上过 GitHub 趋势榜排名第一的位置。正是这个项目让我走上了开源事业的道路。

文档并不是开源项目开发的附属品
|
||||
======
|
||||
有些项目长期保持活跃，有些项目却过早消亡 —— 这两者的区别往往在于它们的文档。严谨、聪明的文档可以给你的项目带来它所需要的动力。你应该把文档工作视为一项主要工作，把它与开发相提并论，下面我将说明这么做的理由和正确的做法。
|
||||
|
||||
![文档的重要性][1]
|
||||
|
||||
经常会有开发者简单地认为他们的代码已经足够“<ruby>自我记录<rt>self-documented</rt></ruby>”了，继而认为额外的文档是没有必要的。这种过度的自信会让项目付出很大的代价。不足或不好的文档会扼杀你的项目。没有适当的文档，用户将无法理解项目的目标以及正确的工作流程。这可能会导致人们对采用你的开源产品产生一些疑虑。
|
||||
|
||||
### 撰写文档，从项目第一天就开始
|
||||
|
||||
文档不应该是次要的工作，它应该是与代码开发和管理同等的主要任务。在 Community Threads、stack overflow 和 Quora 问答等社区中，文档内容广泛传播，其本身承担了“<ruby>信息源<rt>source of truth</rt></ruby>”的角色。 它应该满足那些想参考一手资料的贡献者的需要，并给工程师提供必要的参考支持。它还应该与股东沟通基本计划。一个好的文档可以确保产品的持续改进和发展。
|
||||
|
||||
当发布一个软件产品时，我们不仅要发布代码，还要发布好的文档。这给我们带来了一个最重要的概念，大多数维护着良好文档的开源项目都遵循这个概念 —— “文档即代码”。
|
||||
|
||||
### 文档及代码
|
||||
|
||||
今天，文档不再被存储为 Microsoft Word 或 PDF 文件。新的需求是版本控制文档，其中所有的文档都是通过版本控制系统添加的，并持续发布。这个概念因 Read the Docs（LCTT 译注：一个文档创建、托管和浏览的平台）而流行，现在已经成为大多数文档团队的内容策略的重要组成部分。
|
||||
|
||||
像 Bugzilla 和 GitHub Issues 这样的工具可以用来跟踪待处理的文档工作，并从维护者和用户那里获得反馈以验证文档的发布。外部审查可以用来验证文档作品，并持续发布文档。这就保证了除代码外，文档也能不断改进并快速发布。
|
||||
|
||||
请记住，如果不遵循任何规范化的实践，每个文档都会不同。这可能会导致一些混乱，使人们难以获取正确的信息。
|
||||
|
||||
哪些东西会被归类为混乱呢？当大多数文件都不遵循规范实践时，不一致就会产生，从而导致一个大混乱！那么，如何整理混乱的开源文档呢？
|
||||
|
||||
### 整理混乱的开源文档
|
||||
|
||||
遵循一个“文档风格指南”是很重要的。风格指南是创建和展示内容的指导方针的集合。无论你是一个独立的作家还是一个大型文档团队的成员，它都有助于在你的文档中保持一致的风格、声音和语气。
|
||||
|
||||
有几个流行的风格指南，如红帽风格指南，谷歌文档风格指南，和苹果风格指南。如何选用？首先要从定义你的需求开始。如果你的要求与其他开源项目没有太大区别，你可以遵循一个现成的风格指南，或者你也可以先选一个，然后在它的基础上根据自身需要做一些修改。大多数与语法有关的准则和内容规则可能是通用的，但整体术语可能会有所不同。
|
||||
|
||||
你还需要在你的项目中自动采用这些风格指南。为此，你可以使用 Vale，它集成了本地的持续集成（CI）服务，该服务能帮助你确保文档严格遵循风格指南。
|
||||
|
||||
### 文档类型
|
||||
|
||||
* 自述文件：包含基本的安装和使用说明，这也是任何开源文档中最重要的部分之一。它是潜在的用户/开发者与项目之间的第一个连接点。
|
||||
* 参考指南：可能包括一些基本的参考资料，以便帮助你快速上手，或者是与项目贡献相关的文档。
|
||||
* 用户文档：是最基本的文档，它描述了项目的使用方式。如果没有任何用户文档，大多数人就会对如何使用该项目感到迷茫。
|
||||
* 开发文档：旨在支持开发团队在项目中不断取得新的进展。它还应该为内部开发工作提供一个良好的途径，并确保功能被很好地传达给股东。
|
||||
* 社区内容：包括基本的博客、视频和外部内容，旨在为那些想进一步了解项目的社区成员提供支持。
|
||||
|
||||
通过使用风格指南，文件的整体前提将以统一的语言风格传达给用户。但是，这些文件是毕竟由一个技术作家团队准备的，它们的写作风格可能会冲突，因为写作风格是因人而异的。那么，如何才能使文档规范化呢？
|
||||
|
||||
### 规范化文档
|
||||
|
||||
当涉及到规范化文档时，有许多方法可以采取。第一个方法显然是创建适用于各种角色的预定义模板。这些模板可以用来记录新的功能、识别错误和问题，以及更新变更日志以适应正在增加的新内容。
|
||||
|
||||
如果你采用的是基于 Git 的工作流，试着开发一个规范的工作流程来发布你的文档。最规范的工作流是：<ruby>复刻<rt>fork</rt></ruby>发布文档的仓库，在本地分支上添加你的修改，推送这些修改，提出请求并要求对其进行审查。规范化文档的一个好处就是带来更好的反馈和审查过程。
|
||||
|
||||
### 反馈和自动审查
|
||||
|
||||
规范化使得你能够得到用户的反馈并生成自动的审查，这些反馈可以被考虑用来改进项目和文档。通过这些反馈，你也可以评估所分享的信息对用户是否有意义。像 GitBook 这样的文档平台会提供合适的反馈服务，这有助于验证文档是否有用。
|
||||
|
||||
始终寻求主题专家（SME）对文档的反馈，他们可以是股东、开发者、工程师，甚至是外部贡献者。你也可以使用自动测试和CI来验证你的文档是否遵循风格指南。
|
||||
|
||||
### 文档众包
|
||||
|
||||
如果你想开源你的文档，最好的方法也许是提供一个快速入门指南。它可以像“CONTRIBUTING.md”那样简单，基本上只要说明该如何设置项目并为其作出贡献/单纯使用它即可。
|
||||
|
||||
始终开发以用户为中心的文档，它介绍了项目的目标。同时，打造学习课程来帮助新的贡献者。
|
||||
|
||||
### 带着目的编写文档
|
||||
|
||||
始终带着目的编写文档。它是最基本的写作策略之一，它定义了你编写某个特定文档的理由，而非方式。首先回答以下问题：
|
||||
|
||||
* 这个文档的目标是什么？
|
||||
* 需要传递的信息是什么？
|
||||
* 你希望用户在这之后采取什么行动？
|
||||
* 我与读者分享的价值观是什么？
|
||||
* 我的文档风格是否简洁、一致？
|
||||
|
||||
### 定义一致的内容策略
|
||||
|
||||
一致的内容策略有助于确保文档工作和项目基础设施的长期愿景。它可以围绕以下两个主要方面：
|
||||
|
||||
1. 资源：包括项目文档、案例研究和白皮书、项目架构等
|
||||
2. 品牌内容：博客和特邀帖子、新闻和社区故事、学习课程等
|
||||
|
||||
每个开源项目都应该有适当的文档，以说明它能为用户提供的功能，这样用户就可以选择最合适的解决方案。适当的文档可以传达正确的信息，也可以让其他开发者贡献力量来进一步加强和改进项目。虽然听起来很简单，但只有做对了，文档才能成功。而你的项目，反过来，只有在你的文档是正确的情况下才能成功，所以永远不要低估它的目标或过程!

保护 WordPress 网站的 6 个提示
|
||||
======
|
||||
即使初学者也可以并且应该采取这些步骤来保护他们的 WordPress 网站免受网络攻击。
|
||||
|
||||
![A lock on the side of a building][1]
|
||||
|
||||
已经驱动了互联网 30% 的网站，不难看出， WordPress 是世界上增长最快的 <ruby>CMS<rt>内容管理系统</rt></ruby>。通过大量可用的定制化代码和插件，顶级的 <ruby>SEO<rt>搜索引擎优化</rt></ruby> ，和一个在博客界超高的美誉度，WordPress 确实赢得了它的流行度。
|
||||
|
||||
然而，随着流行度而来的，还有些不太吸引人的注意。WordPress 是入侵者，恶意软件和网络攻击的常规目标，事实上，在2019年，WordPress 遭受了大约 [<ruby>CMS<rt>内容管理系统</rt></ruby> 平台 90% 的黑客攻击][2].
|
||||
|
||||
无论你是 WordPress 新用户或者有经验的开发者，这里有一些你可以采取的重要步骤来保护你的 WordPress 网站。以下 6 个关键提示将帮助你开始。
|
||||
|
||||
|
||||
### 1\. 选择可靠的托管主机
|
||||
|
||||
主机是所有网站无形的基础，没有它，你不能在线发布你的网站。但是主机比起简单的托管你的网站还能做的更多。它也要对你的网站速度，性能和安全负责。
|
||||
|
||||
第一件要做的事情就是检查主机在它的套餐中是否包含 SSL 安全协议。
|
||||
|
||||
无论你是运行一个小博客或是一个大的在线商店，SSL 协议都是所有网站必需的安全功能。如果你正在进行线上交易，你还需要 [高级 SSL 数字证书][3] ，但是对大多数网站来说，基本免费的 SSL 协议就很好了。
|
||||
|
||||
|
||||
其他的安全功能包括以下几种：
|
||||
|
||||
* 日常的自动离线网站备份
|
||||
* 恶意软件和杀毒软件扫描和删除
|
||||
* <ruby>DDOS<rt>分布式服务攻击</rt></ruby>保护
|
||||
* 实时网络检测
|
||||
* 高级防火墙保护
|
||||
|
||||
|
||||
另外除了这些数字安全功能之外，你的主机供应商的 _物理_ 安全措施也是值得考虑的。这些包括安全警卫，<ruby>CCTV<rt>闭路电视</rt></ruby>和二次验证或生物识别来限制对数据中心的访问。
|
||||
|
||||
### 2\. 使用安全插件
|
||||
|
||||
保护你的网站安全最有效且容易的方法之一是安装一个安全插件，比如 [Sucuri][4] 这样的具有 GPLv2 许可项目的开源软件，安全插件是非常重要的，因为他们能自动化管理安全，这意味着你能够集中精力运行好你的网站而不是花大量的时间来与在线网站的威胁作斗争。
|
||||
|
||||
这些插件探测到并阻止恶意攻击并关于这些问题警告你来获取你的注意。简言之，它们持续在后台运行保护你的网站，意味着你不必保持7天24小时保持清醒与黑客，漏洞和其他数字垃圾斗争。
|
||||
|
||||
一个好的安全插件会免费提供给你所有必要的安全功能，但是一些高级功能区要付费订阅。举个例子，如果你想要解锁 [Sucuri 的网站防火墙l][5] ，你需要付费。开启 <ruby>WAF<rt>网络程序防火墙</rt></ruby> 阻挡常规威胁然后给你的网站加入一个额外的安全层，所以当选择安全插件的时候，寻找这个功能是一个好的主意。
|
||||
|
||||
### 3\. 选择值得信任的插件和主题
|
||||
|
||||
WordPress 的快乐在于它是开源的，所以任何人，每个人都能加入他们开发的主题和插件。当选择高质量的主题和插件时，这也抛出一些问题。
|
||||
|
||||
在加入免费主题或插件时，有一些是设计较为差的或者糟糕的，可能会隐藏恶意代码。
|
||||
|
||||
为了避免这种情况，始终从可靠的来源来获取免费主题和插件，比如 WordPress 主题库。阅读评论并研究查看开发者是否编译了一些其他的程序。
|
||||
|
||||
过期和设计较差的主题和插件可能留有 "后门" 对袭击者开放或者存在进入你网站的漏洞，这就是为什么选择时要谨慎。然而，你也应该提防无效或者被破解的主题。这些高级主题已经被黑客重新编译并非法销售。你可能会相信买一个无效的主题，它看起来没什么问题，但会通过隐藏的恶意代码破坏你的网站。
|
||||
|
||||
为了避免无效主题，不要被打折的价格所吸引，始终坚持可靠的主题商店，比如官方的 [WordPress 目录][6]。如果你要找其他的主题，坚持找大的且信任的商店，比如 [Themify][7] ，自从 2010 年，这个主题和插件商店就已经在经营了。Themify 确保它的所有 WordPress 主题通过 [<ruby>Google Mobile-Friendly<rt>谷歌友好移动</rt></ruby>][8] 测试和 [<ruby>GNU<rt>通用公共许可证</rt></ruby>][9]。
|
||||
|
||||
### 4\. 运行日常更新
|
||||
|
||||
这是 WordPress 的基本规则： _始终保持你的网站最新._ 然而，不是所有人都坚持了这个规则，只有 [43% 的 WordPress 网站][10] 是运行的最新版本。
|
||||
|
||||
问题是当你的网站过期的时候，由于它在安全和性能修复方面的原因，故障，漏洞，入侵和破坏会变得更加容易出现。过期的网站不能修复漏洞，而更新过的可以，攻击者能够分辨出哪些网站是过期的。这意味着他们能够依此来搜索最易受攻击的网站并袭击它们。
|
||||
|
||||
这就是为什么你始终要运行最新的 WordPress 版本的原因。为了保持网站安全是最强的，你必须更新你的插件和主题以及你的核心 WordPress 软件。
|
||||
|
||||
如果你选择一个可管理的 WordPress 托管套餐，你可能会发现你的提供商会检查并运行你的主机是否提供的软件 _和_ 插件更新。如果没有，你可以安装一个开源插件管理器。比如 GPLv2 许可的 [Easy Updates Manager plugin][11] 作为替代品。
|
||||
|
||||
### 5\. 强化你的登录
|
||||
|
||||
|
||||
除了通过仔细选择主题和安装安全插件来创建一个安全的 WordPress 网站外，你还需要防止未经授权的登录访问。
|
||||
|
||||
#### 密码保护
|
||||
|
||||
如果你在使用 [容易猜到的短语][12] 比如 "123456" 或 "qwerty" ，第一步要做的增强登录安全最简单的方法是更改你特定的密码。
|
||||
|
||||
尝试使用一个长密码段而不是一个单词，这样他们很难破解。最好的方式是用一系列你容易记住且不相关的单词合并加强。
|
||||
|
||||
这里有一些其它的提示：
|
||||
|
||||
* Never reuse passwords 绝不要重复使用密码
|
||||
* 密码不要包括像家庭成员的名字或者你喜欢的球队等明显的单词
|
||||
* 不要和任何人分享你的登录信息
|
||||
* 你的密码段要包括大小写和数字来增加复杂程度
|
||||
* 不要在任何地方写下或者存储你的登录信息
|
||||
* 使用 [密码管理器][13]
|
||||
|
||||
|
||||
|
||||
#### 变更你的登录地址
|
||||
|
||||
将标准格式的默认登录网址变更是一个好的主意：yourdomain.com/wp-admin。 这是因为黑客知道这是缺省登录网址，所以不变更会有暴力破解的风险。
|
||||
|
||||
为避免这种情况，变更登录网址到和以前有些不同。使用开源插件比如 GPLv2 许可的 [WPS Hide Login][14] 会更加安全，快速和轻松的自定义登录地址。
|
||||
|
||||
|
||||
#### 应用二次验证
|
||||
|
||||
对于额外阻止未授权的登录和暴力破解，你应该添加二次验证。这意味着即使有人 _确实_ 访问到你的登录信息，但是他们还需要一个直接发送到你手机的验证码来获得存取 WordPress 网站管理的权限。
|
||||
|
||||
添加二次验证是非常容易的，简单的安装另一个插件，在 WordPress 插件目录搜索 "二次验证" ，然后选择你要的插件。一个选择是 [Two Factor][15] ，这是比较火的 GPLv2 许可的插件，已经超过 10000 安装次数。
|
||||
|
||||
|
||||
#### 限制登录尝试
|
||||
|
||||
WordPress 通过让你多次猜你的登录信息来尝试帮助你登录。然而，这对黑客尝试获取未授权访问 WordPress网站释放恶意代码也是有帮助的。
|
||||
|
||||
为了应对暴力破解，安装插件来限制登录尝试并设置你要允许猜解的次数。
|
||||
|
||||
### 6\. 禁用文件编辑功能
|
||||
|
||||
这不是对初学者友好的步骤，所以不要尝试除非你是个自信的码农并且一直优先备份你的网站。
|
||||
|
||||
那就是说，如果关于保护你的 WordPress 网站是认真的，禁用文件编辑功能 _是_ 一个重要的措施 。如果你不隐藏你的文件，它意味着任何人从管理员区域都可以编辑你的主题和插件代码，如果入侵者进入，那就危险了。
|
||||
|
||||
为了拒绝未授权的访问，转到你的 **wp-config.php** 文件并打开：
|
||||
|
||||
|
||||
```
|
||||
<Files wp-config.php>
|
||||
order allow,deny
|
||||
deny from all
|
||||
</Files>
|
||||
```
|
||||
|
||||
或者，从你的 WordPress 管理区直接删除主题和插件的编辑选项，通过添加编辑你的 **wp-config.php** 文件：
|
||||
|
||||
|
||||
```
|
||||
`define( 'DISALLOW_FILE_EDIT', true );`
|
||||
```
|
||||
|
||||
一旦你保存并重新加载这个文件，插件和主题编辑器将会从你的 WordPress 管理区菜单中消失，阻止任何人编辑你的主题或者插件代码，包括你自己 **.** 当你禁用编辑的状态下，需要恢复访问你的主题和插件代码的时候，只需要删除你添加在 **wp-config.php** 文件中的代码即可。
|
||||
|
||||
无论你阻止未授权的访问还是总的禁用文件编辑功能，采取保护你网站代码的行动是重要的。否则，不受欢迎的访问者编辑你的文件并添加新代码是很容易的。这意味着袭击者可以使用编辑器从你的 WordPress 站点来获取数据或者甚至利用你的网站对其他站点发起攻击。
|
||||
|
||||
隐藏文件更容易的方式是利用安全插件来为你服务，比如 Sucuri 。
|
||||
|
||||
### WordPress 安全概要
|
||||
|
||||
WordPress是一个优秀的开源平台，初学者和开发者都应该享受它，而不用担心成为攻击的受害者。遗憾的是，这些威胁不会去任何地方，保持网站的安全性至关重要。
|
||||
|
||||
利用以上措施，你可以创建一个更加强壮，更高安全保护级别的 WordPress 站点并确保给自己带来更好的使用体验。
|
||||
|
||||
保持安全是一个持续的任务而不是一次性的检查清单，所以当搭建和使用 <ruby>CMS<rt>内容管理系统</rt></ruby> 时，一定要在日常中回顾这些步骤并保持警惕。

使用 Go 和树莓派来解决 WiFi 问题
|
||||
======
|
||||
实现一个 WiFi 扫描仪玩玩～
|
||||
|
||||
![在在门廊上喝茶][1]

||||

|
||||
|
||||
去年夏天，我和妻子卖掉了我们的全部财产，带着我们的两只狗搬到了夏威夷。这里有我们想象中的一切：美丽的阳光、温暖的沙滩、凉爽的冲浪 —— 你能想到的一切。我们也遇到了一些意料之外的事：WiFi 问题。
|
||||
|
||||
不过，这不是夏威夷的问题，而是我们租住的公寓的问题。我们住在一个单身公寓里，与房东的公寓仅一墙之隔。我们的租房协议中包含了免费的网络连接！好耶！只不过，它是由房东的公寓里的 WiFi 提供的，哇哦……
|
||||
|
||||
说实话，它的效果还不错……吗？好吧，我承认它不尽如人意，我也不知道是哪里出了问题。明明路由器就在墙的另一边，但我们的信号就是很不稳定，经常会自动断开连接。在家的时候，我们的 WiFi 路由器的信号能够穿过层层墙壁和地板。事实上，它所覆盖的区域比我们居住的 600 平方英尺（大约 55 平方米）的公寓还要大。
|
||||
|
||||
在这种情况下，一个优秀的技术人员会怎么做呢？既然想知道为什么，当然是开始调查咯！
|
||||
|
||||
幸运的是，我们在搬家之前卖掉的“全部财产”并不包括树莓派 Zero W。它是如此小! 如此便携! 我当然就把它一起带来了。我有一个机智的想法：使用树莓派和它内置的 WiFi 适配器，用 Go 语言编写一个小程序来测量并显示从路由器收到的 WiFi 信号。我打算先简单快速地把它实现出来，以后再去考虑该如何优化。烦死了！我现在只想知道这个 WiFi 是怎么回事！
|
||||
|
||||
谷歌搜索了一番后，我发现了一个相对有用的 Go 软件包 [mdlayher/wifi][2]，它专门用于 WiFi 相关操作，听起来很有希望！
|
||||
|
||||
### 获取 WiFi 接口的信息
|
||||
|
||||
我的计划是查询 WiFi 接口的统计数据并返回信号强度，所以我需要先找到设备上的接口。幸运的是，mdlayher/wifi 包有一个查询它们的方法，所以我可以创建一个 `main.go` 来实现它，就像下面这样：
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"github.com/mdlayher/wifi"
|
||||
)
|
||||
|
||||
func main() {
|
||||
c, err := wifi.New()
|
||||
defer c.Close()
|
||||
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
interfaces, err := c.Interfaces()
|
||||
|
||||
for _, x := range interfaces {
|
||||
fmt.Printf("%+v\n", x)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
让我们来看看上面的代码都做了什么吧！嗯，首先是导入依赖模块，导入后，我就可以使用 mdlayher/wifi 模块就在主函数中创建一个新的客户端（类型为 `*Client`）。接下来，这个新的客户端（变量名为 `c`）就可以获得系统中的接口列表，只需要调用 `c.Interfaces()` 方法即可。接着，我就可以遍历包含接口指针的切片（变长数组），然后打印出它们的具体信息。
|
||||
|
||||
注意到 `%+v` 中有一个 “+” 了吗？它意味着程序会额外打印出 `*Interface` 结构中的属性名，这将有助于我辨认出我看到的东西，而不用回头去看文档。
|
||||
|
||||
运行上面的代码后，我得到了机器上的 WiFi 接口列表：
|
||||
|
||||
```
|
||||
&{Index:0 Name: HardwareAddr:5c:5f:67:f3:0a:a7 PHY:0 Device:3 Type:P2P device Frequency:0}
|
||||
&{Index:3 Name:wlp2s0 HardwareAddr:5c:5f:67:f3:0a:a7 PHY:0 Device:1 Type:station Frequency:2412}
|
||||
```
|
||||
|
||||
注意，两行输出中的 MAC 地址都是 `HardwareAddr`，这意味着它们是同一个物理硬件。你也可以通过 `PHY: 0` 来确认。根据 Go 的 [wifi 模块文档][3]，`PHY` 指的就是接口所属的物理设备。
|
||||
|
||||
第一个接口没有名字，类型是 `TYPE: P2P`。第二个接口名为 `wpl2s0`，类型是 `TYPE: Station`。Go 的 wifi 模块文档列出了 [不同类型的接口][4]，并描述了它们是什么。根据文档，“<ruby>P2P<rt>点对点传输</rt></ruby>” 类型表示“这个接口是点对点客户端网络中的一个设备”。我认为这个接口是用于 [WiFi 直连][5] 的，这是一个允许两个 WiFi 设备在没有中间接入点的情况下直接连接的标准。
|
||||
|
||||
“<ruby>Station<rt>基站</rt></ruby>” 类型表示“这个接口是带有<ruby>控制接入点<rt>controlling access point</rt></ruby>的客户端设备管理的<ruby>基本服务集（BSS）<rt>basic service set</rt></ruby>的一部分”。这是大多数人所习惯的无线设备标准功能，也就是作为一个客户端来连接到网络接入点。这也是测试 WiFi 质量的重要接口。
|
||||
|
||||
### 利用接口获取基站信息
|
||||
|
||||
利用这个信息，我可以修改遍历接口的代码来获取我正在寻找的信息：
|
||||
|
||||
```go
|
||||
for _, x := range interfaces {
|
||||
if x.Type == wifi.InterfaceTypeStation {
|
||||
// c.StationInfo(x) returns a slice of all
|
||||
// the staton information about the interface
|
||||
info, err := c.StationInfo(x)
|
||||
if err != nil {
|
||||
fmt.Printf("Station err: %s\n", err)
|
||||
}
|
||||
for _, x := range info {
|
||||
fmt.Printf("%+v\n", x)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
首先，这段程序检查了 `x.Type`（接口类型）是否为 `wifi.InterfaceTypeStation`，它是一个基站接口（也是本练习中唯一涉及到的类型）。这是一个不幸的命名冲突，因为这个接口“类型”和 Golang 中的“类型”不是一个东西。事实上，我在这里使用了一个叫做 `interfaceType` 的 Go 类型来代表接口类型。呼，我花了一分钟才弄明白！
|
||||
|
||||
然后，假设接口的类型符合预期，我们就可以调用 `c.StationInfo(x)` 来检索基站信息，`StationInfo()` 方法可以获取到关于这个接口 `x` 的信息。
|
||||
|
||||
这将返回一个包含 `*StationInfo` 指针的切片。我不大确定这里为什么要用切片，或许是因为接口可能返回多个 `StationInfo`？不管怎么样，我都可以遍历这个切片，然后使用之前提到的 `+%v` 技巧格式化打印出 `StationInfo` 结构的属性名和属性值。
|
||||
|
||||
运行上面的程序后，我得到了下面的输出：
|
||||
|
||||
```
|
||||
&{HardwareAddr:70:5a:9e:71:2e:d4 Connected:17m10s Inactive:1.579s ReceivedBytes:2458563 TransmittedBytes:1295562 ReceivedPackets:6355 TransmittedPackets:6135 ReceiveBitrate:2000000 TransmitBitrate:43300000 Signal:-79 TransmitRetries:2306 TransmitFailed:4 BeaconLoss:2}
|
||||
```
|
||||
|
||||
我感兴趣的是“<ruby>信号<rt>Signal</rt></ruby>”部分，可能还有“<ruby>传输失败<rt>TransmitFailed</rt></ruby>”和“<ruby>信标丢失<rt>BeaconLoss</rt></ruby>”部分。信号强度是以 dBm（全称 <ruby>decibel-milliwatts<rt>分贝-毫瓦</rt><ruby>）为单位来报告的。
|
||||
|
||||
#### 简短科普：如何读懂 WiFi dBm
|
||||
|
||||
根据 [MetaGeek][6] 的说法：
|
||||
|
||||
* -30 最佳，但它既不现实也没有必要
|
||||
* -67 非常好，它适用于需要可靠数据包传输的应用，例如流媒体
|
||||
* -70 还不错，它是实现可靠数据包传输的底线，适用于电子邮件和网页浏览
|
||||
* -80 很差，只能保持绝对的基本连接，不可靠的数据包传输
|
||||
* -90 不可用，接近“<ruby>噪音底线<rt>noise floor</rt></ruby>”
|
||||
|
||||
*注意：dBm 是对数尺度，-60 比 -30 要低 1000 倍。*
|
||||
|
||||
### 使它成为一个真的“扫描仪”
|
||||
|
||||
所以，看着上面输出显示的我的信号：-79。哇哦，感觉不大好呢。不过单看这个结果并没有太大帮助，它只能提供某个时间点的参考，只对 WiFi 网络适配器在那一瞬间所在的特定物理空间有效。一个连续的读数会更有用，它能使我们有可能看到信号随着树莓派的移动而变化。我可以再次修改主函数来实现这一点。
|
||||
|
||||
```go
|
||||
var i *wifi.Interface
|
||||
|
||||
for _, x := range interfaces {
|
||||
if x.Type == wifi.InterfaceTypeStation {
|
||||
// Loop through the interfaces, and assign the station
|
||||
// to var x
|
||||
// We could hardcode the station by name, or index,
|
||||
// or hardwareaddr, but this is more portable, if less efficient
|
||||
i = x
|
||||
break
|
||||
}
|
||||
}
|
||||
|
||||
for {
|
||||
// c.StationInfo(x) returns a slice of all
|
||||
// the staton information about the interface
|
||||
info, err := c.StationInfo(i)
|
||||
if err != nil {
|
||||
fmt.Printf("Station err: %s\n", err)
|
||||
}
|
||||
|
||||
for _, x := range info {
|
||||
fmt.Printf("Signal: %d\n", x.Signal)
|
||||
}
|
||||
|
||||
time.Sleep(time.Second)
|
||||
}
|
||||
```
|
||||
|
||||
首先，我命名了一个 `wifi.Interface` 类型的变量 `i`。因为它在循环的范围外，所以我可以用它来存储接口信息。循环内创建的任何变量在该循环的范围外都是不可访问的。
|
||||
|
||||
然后，我可以把这个循环一分为二。第一个遍历了 `c.Interfaces()` 返回的接口切片，如果元素是一个 `Station` 类型，它就将其存储在先前创建的变量 `i`中，并跳出循环。
|
||||
|
||||
第二个循环是一个无限循环，所以它将不断地运行，直到我按下 **Ctrl** + **C** 来结束程序。和之前一样，这个循环内部获取接口信息、检索基站信息，并打印出信号信息。然后它会休眠一秒钟，再次运行，反复打印信号信息，直到我退出为止。
|
||||
|
||||
运行上面的程序后，我得到了下面的输出：
|
||||
|
||||
```
|
||||
[chris@marvin wifi-monitor]$ go run main.go
|
||||
Signal: -81
|
||||
Signal: -81
|
||||
Signal: -79
|
||||
Signal: -81
|
||||
```
|
||||
|
||||
哇哦，感觉不妙。
|
||||
|
||||
### 绘制公寓信号分布图
|
||||
|
||||
不管怎么说，知道这些信息总比不知道要好。让树莓派连接上显示器或者电子墨水屏，并接上电源，我就可以让它在公寓里移动，并绘制出信号死角的位置。
|
||||
|
||||
剧透一下：由于房东的接入点在隔壁的公寓里，对我来说最大的死角是公寓厨房的冰箱那里发射出的一个圆锥体形状区域......这个冰箱与房东的公寓共用一堵墙！
|
||||
|
||||
我想如果用《龙与地下城》里的黑话来说，它就是一个“<ruby>沉默之锥<rt>Cone of Silence</rt></ruby>”。或者至少是一个“<ruby>糟糕的网络连接之锥<rt>Cone of Poor Internet</rt></ruby>”。
|
||||
|
||||
总之，这段代码可以直接在树莓派上运行 `go build -o wifi_scanner` 来编译，得到的二进制文件 `wifi_scanner` 可以与任何其他 ARM 设备（同一版本）共享。另外，它也可以在常规系统上用正确的 ARM 设备库进行编译。
|
||||
|
||||
祝你扫描愉快！希望你的 WiFi 路由器不在你的冰箱后面！你可以在 [我的 GitHub repo][7] 中找到这个项目所用的代码。

||||
* JWM 桌面环境
|
||||
|
||||
|
||||
|
||||
#### 3\. BunsenLabs Linux

|
||||
#### 4\. Lubuntu
|
||||
|
||||
Lubuntu 是一款著名的轻量级 Linux 发行版。它是一款官方的 Ubuntu Linux 衍生特色版本，其特点是使用轻量级 LxQt桌面环境。Lubuntu 在给予你现代的 Ubuntu Linux 软件包和技术的同时，也针对你的低端硬件提供 LxQt 桌面环境。尽管与这份列表中的其它的发行版相比，它可能需要一些额外的系统资源，但是对于较旧的硬件系统来说，它仍然是一个可接受的 Linux 发行版。

||||
#### 6\. antiX Linux
|
||||
|
||||
我们想重点推荐的另一款轻量级 Linux 发行版是 antiX Linux 。antiX Linux 基于 Debian 的 stable 分支，并带来一些诱人的特色。它的核心是，它使用 IceWM 、Fluxbox 和 ROX 桌面环境选项，给予你一种极好的和快速的桌面体验。它完全是 systemd 自由的，使用 sysVinit 和 runit 系统。antiX Linux 也给予你一个 32-位 安装程序，并且还有种变体 – 完全体、核心体、基本体以及网络体，以满足不同的实际使用情况。

||||
|
||||

|
||||
|
||||
#### 7\. LXLE
|
||||
|

LXLE Linux 是 Lubuntu LTS 系列的一种变体，使用 LXDE 桌面环境而不再使用 LXQt 桌面环境。应用程序、安装程序以及其它的特色的选择使其成针对较旧的硬件系统的一款完美的发行版。它非常适合于复活你的旧硬件系统，使用稳定的 Ubuntu-LTS 基础和快速的 LXDE 桌面环境。
|
||||
|
||||
![LXLE Linux][13]
|
||||
|
||||
然而，就我个人见解，我感觉 LXQt 比 LXDE 稍快一点。好吧，这种反馈可能是因人而异的，对你来说可能是不同的。现在，这里没有多少 Linux 发行版向你提供 LXDE 桌面环境的衍生特色版本。因此，对于你的日常使用的来说，它可能是独特的一款轻量级的 Linux 发行版。
|
||||
|
||||
[下载 LXLE][14]
|
||||
|
||||
#### 8\. Porteus Linux
|
||||
|
||||
Porteus Linux 是 Slackware Linux 的一款混成版本，以旧的 KDE 4.0+ 桌面环境 (在 KDE Plasma 系列之前的版本) 为特色。这款超快的 Linux 发行版非常适合于你的考古级的硬件系统，因为它基于最先进的 Slackware ，并且向你提供一款 32-位 的版本。这款发行版可以从 Live USB 或 Live CD 或任意可启动媒介中运行，安装程序仅 300 MB 大小。

||||
|
||||

|
||||
|
||||

||||
|
||||

||||
|
||||
#### 9\. Q4OS
|
||||
|
||||
Q4OS 是这份列表中的一款独特的 Linux 发行版。它针对现今已经过时的较旧的 windows 系统。曾经很多较旧的 PC 运行 Windows XP 和 Windows 7 。它们在 windows 和一些现代的 Linux 发行版下不再能很好地工作，因为现代的及其更新的操作系统要求更多的计算能力和资源。
|
||||
|
||||
Q4OS 针对这些实际使用实例，给予你一款设计良好的 Linux 发行版，附带有一个 32-位 安装程序、在 Windows 系统中的安装程序、Trinity 桌面环境、预制的 Windows 主题等等。
|
||||
|
||||

|
||||
|
||||
[下载 Q4OS][19]
|
||||
|
||||
#### 10\. MX Linux
|
||||
|
||||
在这份列表中的最后一款 Linux 发行版是著名的 MX Linux ，它凭借其特色和独特性在当今时代留下的印记。然而，我都怀疑是否应该将 MX Linux 列为轻量级。因为在我看来，如果你推敲它的 KDE Plasma 衍生特色版本的味道时，它应该是中等级的 Linux 发行版。
|
||||
|
||||
![MX Linux][20]
|
||||
|
||||
不管怎么说，它所有的一些特色使其成为一款轻量级 Linux 发行版的完美候选版本。MX Linux 基于 Debian 的 Stable 分支，并使用了 antiX 组件创建。它重点向你推荐它自己的用于附加工作流的 MX Linux 原生应用程序。你可以获取使用 KDE Plasma 、Xfce 和 Fluxbox 作为桌面环境的选项。
|
||||
|
||||

|
||||
|
||||
### 总结
|
||||
|
||||
如果你仔细地阅读会发现，我们在这里所列出的大多数的轻量级 Linux 发行版都基于 Debian Linux 。它是真正的 “通用操作系统”。现代的 Linux 桌面环境，像 GNOME 40+ 、KDE Plasma 和 Systemd init 系统，不再兼容较旧的硬件系统。此外，随着技术的进步，引入了更多的软件复杂性，需要更高端的硬件系统。
|
||||
|
||||
尽管如此，我希望你可以从这份列表中获取一些为你的旧笔记本电脑或 PC 选择哪款轻量级 Linux 发行版的灵感。每一款发行版都提供不同的体验，但是都有共同的目标：复活你的较旧的硬件系统。所以，任君采撷。

我最喜欢的 Go 构建选项
|
||||
======
|
||||
这些方便的 Go 构建选项可以帮助你更好地理解 Go 的编译过程。
|
||||
|
||||
![GitHub 推出“开源星期五”][1]
|
||||
|
||||
(图源 Opensource.com)
|
||||
|
||||
学习一门新的编程语言最令人欣慰的部分之一，就是最终运行一个可执行文件，并获得符合预期的输出。当我开始学习 Go 这门编程语言时，我先是阅读一些样本程序来熟悉语法，然后是尝试写一些小的测试程序。随着时间的推移，这种方法帮助我熟悉了编译和构建程序的过程。
|
||||
|
||||
Go 的构建选项提供了方法来更好地控制构建过程。它们还可以提供额外的信息，帮助把这个过程分成更小的部分。在这篇文章中，我将演示我所使用的一些选项。注意：我使用的 build 和 compile 这两个词是同一个意思。
|
||||
|
||||
### 开始使用 Go
|
||||
|
||||
我使用的 Go 版本是 1.16.7。但是，这里给出的命令应该也能在最新的版本上运行。如果你没有安装 Go，你可以从 [Go 官网][2] 上下载它，并按照说明进行安装。你可以通过打开一个提示符命令，并键入下面的命令来验证你所安装的版本：
|
||||
|
||||
```
|
||||
$ go version
|
||||
```
|
||||
|
||||
你应该会得到类似下面这样的输出，具体取决于你安装的版本：
|
||||
|
||||
```
|
||||
go version go1.16.7 linux/amd64
|
||||
```
|
||||
|
||||
### Go 程序的基本编译和执行
|
||||
|
||||
我将从一个在屏幕上简单打印 “Hello World” 的 Go 程序示例开始，就像下面这样：
|
||||
|
||||
```
|
||||
$ cat hello.go
|
||||
package main
|
||||
|
||||
import "fmt"
|
||||
|
||||
func main() {
|
||||
fmt.Println("Hello World")
|
||||
}
|
||||
```
|
||||
|
||||
在讨论更高级的选项之前，我将解释如何编译这个 Go 示例程序。我使用了 `build` 命令，后面跟着 Go 程序的源文件名，本例中是 `hello.go`，就像下面这样：
|
||||
|
||||
```
|
||||
$ go build hello.go
|
||||
```
|
||||
|
||||
如果一切工作正常，你应该看到在你的当前目录下创建了一个名为 `hello` 的可执行文件。你可以通过使用 `file` 命令验证它是 ELF 二进制可执行格式（在 Linux 平台上）。你也可以直接执行它，你会看到它输出 “Hello World”。
|
||||
|
||||
```
|
||||
$ ls
|
||||
hello hello.go
|
||||
|
||||
$ file ./hello
|
||||
./hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
|
||||
|
||||
$ ./hello
|
||||
Hello World
|
||||
```
|
||||
|
||||
Go 提供了一个方便的 `run` 命令，以便你只是想看看程序是否能正常工作，并获得预期的输出，而不想生成一个最终的二进制文件。请记住，即使你在当前目录中没有看到可执行文件，Go 仍然会在某个地方编译并生成可执行文件并运行它，然后把它从系统中删除。我将在本文后面的章节中解释。
|
||||
|
||||
```
|
||||
$ go run hello.go
|
||||
Hello World
|
||||
|
||||
$ ls
|
||||
hello.go
|
||||
```
|
||||
|
||||
### 更多细节
|
||||
|
||||
运行我的程序时，上面的命令使我如鱼得水，不费吹灰之力。然而，如果你想知道 Go 在编译这些程序的过程中做了什么，Go 提供了一个 `-x` 选项，它可以打印出 Go 为产生可执行文件所做的一切。
|
||||
|
||||
简单看一下你就会发现，Go 在 `/tmp` 内创建了一个临时工作目录，并生成了可执行文件，然后把它移到了 Go 源程序所在的当前目录。
|
||||
|
||||
```
|
||||
$ go build -x hello.go
|
||||
|
||||
WORK=/tmp/go-build1944767317
|
||||
mkdir -p $WORK/b001/
|
||||
|
||||
<< snip >>
|
||||
|
||||
mkdir -p $WORK/b001/exe/
|
||||
cd .
|
||||
/usr/lib/golang/pkg/tool/linux_amd64/link -o $WORK \
|
||||
/b001/exe/a.out -importcfg $WORK/b001 \
|
||||
/importcfg.link -buildmode=exe -buildid=K26hEYzgDkqJjx2Hf-wz/\
|
||||
nDueg0kBjIygx25rYwbK/W-eJaGIOdPEWgwC6o546 \
|
||||
/K26hEYzgDkqJjx2Hf-wz -extld=gcc /root/.cache/go-build /cc \
|
||||
/cc72cb2f4fbb61229885fc434995964a7a4d6e10692a23cc0ada6707c5d3435b-d
|
||||
/usr/lib/golang/pkg/tool/linux_amd64/buildid -w $WORK \
|
||||
/b001/exe/a.out # internal
|
||||
mv $WORK/b001/exe/a.out hello
|
||||
rm -r $WORK/b001/
|
||||
```
|
||||
这有助于解决程序运行后，在当前目录下没有生成可执行文件的问题。使用 `-x` 显示可执行文件确实在 `/tmp` 工作目录下创建并被执行。然而，与 `build` 命令不同的是，可执行文件并没有移动到当前目录，这使得看起来没有可执行文件被创建。
|
||||
|
||||
```
|
||||
$ go run -x hello.go
|
||||
|
||||
|
||||
mkdir -p $WORK/b001/exe/
|
||||
cd .
|
||||
/usr/lib/golang/pkg/tool/linux_amd64/link -o $WORK/b001 \
|
||||
/exe/hello -importcfg $WORK/b001/importcfg.link -s -w -buildmode=exe -buildid=hK3wnAP20DapUDeuvAAS/E_TzkbzwXz6tM5dEC8Mx \
|
||||
/7HYBzuaDGVdaZwSMEWAa/hK3wnAP20DapUDeuvAAS -extld=gcc \
|
||||
/root/.cache/go-build/75/ \
|
||||
7531fcf5e48444eed677bfc5cda1276a52b73c62ebac3aa99da3c4094fa57dc3-d
|
||||
$WORK/b001/exe/hello
|
||||
Hello World
|
||||
```
|
||||
|
||||
### 模仿编译而不产生可执行文件
|
||||
|
||||
假设你不想编译程序并产生一个实际的二进制文件，但你确实想看到这个过程中的所有步骤。你可以通过使用 `-n` 这个构建选项来做到这一点，该选项会打印出通常的执行步骤，而不会实际创建二进制文件。
|
||||
|
||||
```
|
||||
$ go build -n hello.go
|
||||
```
|
||||
|
||||
### 保存临时目录
|
||||
|
||||
很多工作都发生在 `/tmp` 工作目录中，一旦可执行文件被创建和运行，它就会被删除。但是如果你想看看哪些文件是在编译过程中创建的呢？Go 提供了一个 `-work` 选项，它可以在编译程序时使用。`-work` 选项除了运行程序外，还打印了工作目录的路径，但它并不会在这之后删除工作目录，所以你可以切换到该目录，检查在编译过程中创建的所有文件。
|
||||
|
||||
```
|
||||
$ go run -work hello.go
|
||||
WORK=/tmp/go-build3209320645
|
||||
Hello World
|
||||
|
||||
$ find /tmp/go-build3209320645
|
||||
/tmp/go-build3209320645
|
||||
/tmp/go-build3209320645/b001
|
||||
/tmp/go-build3209320645/b001/importcfg.link
|
||||
/tmp/go-build3209320645/b001/exe
|
||||
/tmp/go-build3209320645/b001/exe/hello
|
||||
|
||||
$ /tmp/go-build3209320645/b001/exe/hello
|
||||
Hello World
|
||||
```
|
||||
|
||||
### 其他编译选项
|
||||
|
||||
如果说，你想手动编译程序，而不是使用 Go 的 `build` 和 `run` 这两个方便的命令，最后得到一个可以直接由你的操作系统（这里指 Linux）运行的可执行文件。那么，你该怎么做呢？这个过程可以分为两部分：编译和链接。你可以使用 `tool` 选项来看看它是如何工作的。
|
||||
|
||||
首先，使用 `tool compile` 命令产生结果的 `ar` 归档文件，它包含了 `.o` 中间文件。接下来，对这个 `hello.o` 文件执行 `tool link` 命令，产生最终的可执行文件，然后你就可以运行它了。
|
||||
|
||||
```
|
||||
$ go tool compile hello.go
|
||||
|
||||
$ file hello.o
|
||||
hello.o: current ar archive
|
||||
|
||||
$ ar t hello.o
|
||||
__.PKGDEF
|
||||
_go_.o
|
||||
|
||||
$ go tool link -o hello hello.o
|
||||
|
||||
$ file hello
|
||||
hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
|
||||
|
||||
$ ./hello
|
||||
Hello World
|
||||
```
|
||||
|
||||
如果你想进一步查看基于 `hello.o` 文件产生可执行文件的链接过程，你可以使用 `-v` 选项，它会搜索每个 Go 可执行文件中包含的 `runtime.a` 文件。
|
||||
|
||||
```
|
||||
$ go tool link -v -o hello hello.o
|
||||
HEADER = -H5 -T0x401000 -R0x1000
|
||||
searching for runtime.a in /usr/lib/golang/pkg/linux_amd64/runtime.a
|
||||
82052 symbols, 18774 reachable
|
||||
1 package symbols, 1106 hashed symbols, 77185 non-package symbols, 3760 external symbols
|
||||
81968 liveness data
|
||||
```
|
||||
|
||||
### 交叉编译选项
|
||||
|
||||
现在我已经解释了 Go 程序的编译过程，接下来，我将演示 Go 如何通过在实际的 `build` 命令之前提供 `GOOS` 和 `GOARCH` 这两个环境变量，来允许你构建针对不同硬件架构和操作系统的可执行文件。
|
||||
|
||||
这有什么用呢？举个例子，你会发现为 ARM（arch64）架构制作的可执行文件不能在 Intel（x86_64）架构上运行，而且会产生一个 Exec 格式错误。
|
||||
|
||||
下面的这些选项使得生产跨平台的二进制文件变得小菜一碟：
|
||||
|
||||
```
|
||||
$ GOOS=linux GOARCH=arm64 go build hello.go
|
||||
|
||||
$ file ./hello
|
||||
./hello: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), statically linked, not stripped
|
||||
|
||||
$ ./hello
|
||||
bash: ./hello: cannot execute binary file: Exec format error
|
||||
|
||||
$ uname -m
|
||||
x86_64
|
||||
```
|
||||
|
||||
你可以阅读我之前的博文，了解更多我在 [使用 Go 进行交叉编译][3] 方面的经验。
|
||||
|
||||
### 查看底层汇编指令
|
||||
|
||||
源代码并不会直接转换为可执行文件，尽管它生成了一种中间汇编格式，然后最终被汇编为可执行文件。在 Go 中，这被映射为一种中间汇编格式，而不是底层硬件汇编指令。
|
||||
|
||||
要查看这个中间汇编格式，请在使用 `build` 命令时，提供 `-gcflags` 选项，后面跟着 `-S`。这个命令将会显示使用到的汇编指令：
|
||||
|
||||
```
|
||||
$ go build -gcflags="-S" hello.go
|
||||
# command-line-arguments
|
||||
"".main STEXT size=138 args=0x0 locals=0x58 funcid=0x0
|
||||
0x0000 00000 (/test/hello.go:5) TEXT "".main(SB), ABIInternal, $88-0
|
||||
0x0000 00000 (/test/hello.go:5) MOVQ (TLS), CX
|
||||
0x0009 00009 (/test/hello.go:5) CMPQ SP, 16(CX)
|
||||
0x000d 00013 (/test/hello.go:5) PCDATA $0, $-2
|
||||
0x000d 00013 (/test/hello.go:5) JLS 128
|
||||
|
||||
<< snip >>
|
||||
```
|
||||
|
||||
你也可以使用 `objdump -s` 选项，来查看已经编译好的可执行程序的汇编指令，就像下面这样：
|
||||
|
||||
```
|
||||
$ ls
|
||||
hello hello.go
|
||||
|
||||
$ go tool objdump -s main.main hello
|
||||
TEXT main.main(SB) /test/hello.go
|
||||
hello.go:5 0x4975a0 64488b0c25f8ffffff MOVQ FS:0xfffffff8, CX
|
||||
hello.go:5 0x4975a9 483b6110 CMPQ 0x10(CX), SP
|
||||
hello.go:5 0x4975ad 7671 JBE 0x497620
|
||||
hello.go:5 0x4975af 4883ec58 SUBQ $0x58, SP
|
||||
hello.go:6 0x4975d8 4889442448 MOVQ AX, 0x48(SP)
|
||||
|
||||
<< snip >>
|
||||
```
|
||||
|
||||
### 分离二进制文件以减少其大小
|
||||
|
||||
Go 的二进制文件通常比较大。例如, 一个简单的 Hello World 程序将会产生一个 1.9M 大小的二进制文件。
|
||||
|
||||
```
|
||||
$ go build hello.go
|
||||
$
|
||||
$ du -sh hello
|
||||
1.9M hello
|
||||
$
|
||||
$ file hello
|
||||
hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
|
||||
$
|
||||
```
|
||||
|
||||
为了减少生成的二进制文件的大小，你可以分离执行过程中不需要的信息。使用 `-ldflags` 和 `-s -w` 选项可以使生成的二进制文件略微变小为 1.3M。
|
||||
|
||||
```
|
||||
$ go build -ldflags="-s -w" hello.go
|
||||
$
|
||||
$ du -sh hello
|
||||
1.3M hello
|
||||
$
|
||||
$ file hello
|
||||
hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped
|
||||
$
|
||||
```
|
||||
|
||||
### 总结
|
||||
|
||||
我希望这篇文章向你介绍了一些方便的 Go 编译选项，同时帮助了你更好地理解 Go 编译过程。关于构建过程的其他信息和其他有趣的选项，请参考 Go 命令帮助：

Nushell：让你更清楚地了解错误信息的跨平台 Shell
|
||||
======
|
||||
|
||||
_**简介：** Nushell 是一个独特的 Shell，它提供易于阅读的错误信息并提供跨平台支持。在这里可以了解到更多关于它的信息。_
|
||||
|
||||
即使你对使用终端不感兴趣，Linux 终端也常常使一些繁重的工作变得更加轻松，并让你修复东西。因此，可以说，如果你知道自己在做什么，Linux 终端是相当强大的。
|
||||
|
||||
这也是事实！但是当你遇到错误时，问题就出现了。如果你没有足够的使用经验，你将不知道如何解决它。
|
||||
|
||||
虽然错误信息试图传达问题的最佳含义，但不是每个用户都能轻易理解修复。对于初学者来说，这通常需要进行一些研究。但是，如果错误能有更多的清晰度，用户就能更快地解决它。
|
||||
|
||||
不仅仅限于错误信息，例如，你在终端浏览文件时得到的输出结构，也不是最漂亮的。
|
||||
|
||||
![Terminal listing several files][1]
|
||||
|
||||
**你明白我的意思吗？**当然，当你有更多不同类型的文件时，这可能变得更加复杂。而且，你无法从基本的 ls 命令的输出中了解到文件的权限、组等。
|
||||
|
||||
这就是 Nushell 试图解决这个问题的地方。
|
||||
|
||||
### Nushell：一个默认提供用户友好输出的 Shell
|
||||
|
||||
![Nushell example screenshot][2]
|
||||
|
||||
Nushell 也被称为 Nu，它的理念和灵感来自于 [PowerShell][3]、函数式编程语言和现代 [CLI][4] 工具等项目。
|
||||
|
||||
让我给你举个例子，想象一下你只想列出类型与你主目录内的文件相同的输出，包括隐藏文件。那么，要实现这一点，只要输入下面的命令就可以了：
|
||||
|
||||
```
|
||||
|
||||
ls -a | where type == 'file'
|
||||
|
||||
```
|
||||
|
||||
![Listing only files with Nushell][5]
|
||||
|
||||
观察一下它的语法是多么清晰和简单。现在想象一下，用 Nushell 查找进程和名称 ID，它的状态，以及 CPU 或内存消耗是多么容易。**这是它魔法的一部分！**。
|
||||
|
||||
它尽力为你输入的命令提供用户友好的特定组织的输出。
|
||||
|
||||
### Nushell 的特点
|
||||
|
||||
![Error messages in Nu, one of its primary highlights][6]
|
||||
|
||||
根据现有的官方信息，它的一些最受欢迎的功能包括：
|
||||
|
||||
* **管道控制任何操作系统。**Nu 可以在 Linux、macOS 和 Windows 上工作。换句话说，作为一个灵活的跨平台 shell，具有现代感。
|
||||
* **一切都是数据。**Nu 管道使用结构化数据，所以你可以安全地选择、过滤和排序，每次都是同样的方式。
|
||||
* **强大的插件。**使用强大的插件系统，很容易扩展 Nu 的功能。
|
||||
* **容易阅读错误信息。**Nu 操作的是类型化的数据，所以它可以捕捉到其他 shell 所没有的 bug。当错误发生时，Nu 会告诉你确切的位置和原因。
|
||||
* 清晰的 IDE 支持。
|
||||
|
||||
|
||||
|
||||
你可以看看它的[官方文档][7]，以全面了解它的功能和用法。
|
||||
|
||||
### 在你的系统中安装 Nushell
|
||||
|
||||
不幸的是，如果你是一个像我一样的 Ubuntu 用户，你将找不到安装 Nushell 的 apt 仓库。但是，你可以按照它在 [GitHub][8] 上的说明，通过安装所需的依赖项来构建它。
|
||||
|
||||
幸运的是，有一种方法可以在任何发行版上安装它，使用 **Homebrew**。到它的官方网站去探索更多的安装选项。
|
||||
|
||||
[Nushell][9]
|
||||
|
||||
你可以参考我们关于[在 Linux 上安装和使用 Homebrew 包管理器][10]的教程。当你在 Linux 上成功设置了它，你需要输入以下命令来安装 Nushell：
|
||||
|
||||
```
|
||||
|
||||
brew install nushell
|
||||
|
||||
```
|
||||
|
||||
![Installing nushell with Homebrew][11]
|
||||
|
||||
当这个过程完成后，只要输入 `nu` 就可以启动 Nushell shell。**这就完成了！**
|
||||
|
||||
如果你想把 Nushell 设置为你的默认 shell，你可以用命令 **chsh** 来做，但是记住，它仍然在开发中，这就是为什么我们不推荐它用于日常使用。
|
||||
|
||||
然而，在你决定尝试之前，你可以在其网站或 [GitHub 页面][8]上探索更多关于它的信息。
|
||||

使 Ubuntu 22.04 LTS 成为史诗版本的 5 个不太流行的功能
|
||||
======
|
||||
一份关于 Ubuntu 22.04 LTS 的次要特点的列表，这些特点使它成为迄今为止最好的 LTS 版本之一。
|
||||
|
||||
Canonical 的最新 LTS 版本 [Ubuntu 代号为 “Jammy Jellyfish”][1] 受到了全球用户的好评。有数百个新的微小功能，也有一些不太流行的功能，没有引起人们的注意。因此，这里有五个独特的 Ubuntu 22.04 版本功能，我们认为这些功能使它成为一个史诗般的版本。
|
||||
|
||||
![Ubuntu 22.04 LTS Desktop \(GNOME\)][2]
|
||||
|
||||
### Ubuntu 22.04 发布 – 五个独特的功能
|
||||
|
||||
#### 为数据驱动的方案进行了优化
|
||||
|
||||
数据分析和处理是当今每个企业的核心。而要做到这一点，你需要巨大的计算能力。Ubuntu 22.04 LTS 带来了开箱即用的 [NVIDIA 虚拟 GPU（vGPU）][3] 驱动支持。这意味着你可以利用 NVIDIA 虚拟 GPU 软件，使你能够在从物理 GPU 服务器共享的虚拟机中使用 GPU 计算能力。
|
||||
|
||||
不仅如此，如果你的业务依赖于 SQL Server，Ubuntu LTS for Azure 带来了 Ubuntu 中的 SQL Server，它由 “Micro$oft” 支持，提供优化的性能和可扩展性。
|
||||
|
||||
#### 改进的活动目录集成
|
||||
|
||||
此外，许多企业在多个工作站中为整个企业用户部署 Ubuntu。而且，部署工作站策略以监测和控制用户访问和各种关键业务控制非常重要。
|
||||
|
||||
活动目录实现了基于策略的工作站管理（在 Ubuntu 20.04 中引入），在这个版本中得到了进一步改善。除此之外，这个版本还带来了 [ADsys][4] 客户端，它有助于通过命令行远程管理组策略、权限升级和远程脚本执行。活动目录现在也支持从这个版本开始与高级组策略对象的安装程序集成。
|
||||
|
||||
#### 实时内核支持
|
||||
|
||||
此外，在 Ubuntu 22.04 LTS 发布期间，Canonical 宣布的一个有趣的消息是提供“实时”内核选项，现在是测试版。对于电信和其他行业来说，一个低延迟的操作系统对于时间敏感的工作是必需的。因此，考虑到这一点和渗透到这些领域的愿景，Ubuntu 22.04 LTS 带来了一个应用了 PREEMPT_RT 补丁的实时内核构建。它可用于 x86_64 和 AArch64 架构。
|
||||
|
||||
然而，[补丁][5]还没有在主线内核中出现，希望它能很快能出现。
|
||||
|
||||
#### 最新的应用、软件包和驱动程序
|
||||
|
||||
除了上述变化之外，这个版本还带来了大量的软件包和工具链的升级。例如，这个版本带来了基于用途的多种 Linux 内核类型，如 Ubuntu 桌面可以选择使用 [Kernel 5.17][6]，而硬件启用的内核仍然是 5.15。
|
||||
|
||||
不仅如此，Ubuntu Server 的特点是长期支持 [Kernel 5.15][8]，而 Ubuntu Cloud 镜像可以选择使用与云供应商合作的更优化的内核。
|
||||
|
||||
此外，如果你是 NVIDIA 用户，值得一提的是，ARM64 上的 NVIDIA 驱动的 Linux 限制模块现在已经可用（在 x86_64 中已经可用）。你可以使用 [ubuntu-drivers][9] 程序来安装和配置 NVIDIA 驱动。
|
||||
|
||||
由于核心模块和子系统的存在，一个完整的操作系统可以完美无缺地工作。因此，考虑到这一点，Ubuntu 22.04 LTS 对它们都进行了仔细的升级，以迎合这个很好的版本。以下是简介。
|
||||
|
||||
* GCC 11.2.0
|
||||
* binutils 2.38
|
||||
* glibc 2.35
|
||||
|
||||
|
||||
* Python 3.10.4
|
||||
* Perl 5.34.0
|
||||
* LLVM 14
|
||||
* golang 1.18
|
||||
* rustc 1.58
|
||||
* OpenJDK 11（可选使用 OpenJDK 18）
|
||||
* Ruby 3.0
|
||||
* PHP 8.1.2Apache 2.4.52
|
||||
* PostgreSQL 14.2
|
||||
* Django 3.2.12
|
||||
* MySQL 8.0
|
||||
* 更新的 NFS 以及 Samba Server
|
||||
* Systemd 249.11
|
||||
* OpenSSL 3.0
|
||||
|
||||
|
||||
* qemu 6.2.0
|
||||
* libvirt 8.0.0
|
||||
* virt-manager 4.0.0
|
||||
|
||||
|
||||
|
||||
#### 性能提升
|
||||
|
||||
但这还不是全部。由于一些长期等待的更新，你应该体验到更快的 Ubuntu 22.04 Jammy Jellyfish 体验，这些体验最终会在这个版本中出现。
|
||||
|
||||
首先，GNOME 桌面的[三重缓冲代码]长期悬而未决。当先前的帧缓冲落后时，三重缓冲会自动启用，它在 Intel 和树莓派驱动中产生了更快的桌面性能。不仅如此，代码还监控最后一帧，以便系统不会遇到过量缓冲的情况。
|
||||
|
||||
其次，改进的电源管理，在运行时对 AMD 和 NVIDIA 的 GPU 起作用，将帮助笔记本电脑用户。
|
||||
|
||||
此外，Wayland 现在是大多数系统的默认显示服务器，除了 NVIDIA GPU 硬件默认为 X11。Wayland 为你提供了更快的跨应用的桌面体验，包括网络浏览器。
|
||||
|
||||
最后，定制的 GNOME 42 及其[独特功能][11]（例如平衡和省电电源配置文件）为重度笔记本电脑用户提供了更多优势。 此外，带有浅色/深色外观的新强调色和选定 GNOME 模块的 GTK4/libadwaita 端口只是这个史诗般的 Ubuntu 22.04 LTS 版本的一个插件。
|
||||
|
||||
### 结论
|
||||
|
||||
总而言之，我相信这是 Canonical 发布的最好的 LTS 版本之一，就上述所有内容的变化和许多其他方面而言。
|
||||
|
||||
我们希望它受到好评并在未来几天保持稳定。

Linux Mint 升级工具 – 以下是它如何工作的
|
||||
======
|
||||
我们通过实际升级测试了 Linux Mint 升级工具（MINTUPGRADE GUI）。 这是我们发现的。
|
||||
|
||||
这个工具正在开发中，可能包含 bug。除非你想做实验，否则请不要在你的日常中使用它。
|
||||
|
||||
### Linux Mint 升级工具
|
||||
|
||||
Linux Mint 团队[宣布][1]，他们建立了一个新的工具来升级 Linux Mint 的重要版本。它被称为 “mintupgrade2”。它目前正在开发中，计划用于升级主要版本。例如，Linux Mint 20 到 21，而不是小版本的升级。
|
||||
|
||||
虽然你可以使用标准的 apt 命令来升级版本，然而，Mint 团队认为主要版本的升级是很棘手的。新用户很难进行无缝升级，因为它涉及到终端和一套复杂的命令步骤。
|
||||
|
||||
此外，GUI 是 mintupgrade 程序的一个带有附加功能的封装，它带来了一套系统前检查和一键修复的升级过程。
|
||||
|
||||
除此之外，mintupgrade 还会检查你是否连接到电源，系统是否是最新的，磁盘空间的可用性和更多的功能。
|
||||
|
||||
为了让大家了解它的外观和工作情况，我们使用 LMDE 4 设置了一个测试平台并试一试。
|
||||
|
||||
但在这之前，这里有一组快速的功能：
|
||||
|
||||
* 完全由 GUI 驱动的升级过程
|
||||
* 多语言支持
|
||||
* 升级前检查：系统备份、电源、磁盘空间、删除的软件包列表
|
||||
* 可配置
|
||||
* 提醒你上一版本的无主软件包的情况
|
||||
* 它让你可以选择修复问题
|
||||
|
||||
|
||||
|
||||
### 它是如何工作的
|
||||
|
||||
当我们通过命令 mintupgrade 运行 mint 升级工具时，GUI，友好的欢迎屏幕给你一个很好的起点，开始了升级过程。然后它自己开始进行一系列的检查。
|
||||
|
||||
![Starting the upgrade process][2]
|
||||
|
||||
除此之外，当它在你的系统中发现一些问题时，它会停下来并给你足够的细节。当你点击修复后，它就可以再次恢复进程。
|
||||
|
||||
这还不是全部。如果由于网络或互联网或任何其他问题而中断，它也可以恢复升级过程。
|
||||
|
||||
在我们的测试过程中，该工具在我们的测试系统中发现了以下错误，只需点击一下就能修复它们。
|
||||
|
||||
![Apt Cache check][3]
|
||||
|
||||
![Mint Upgrade detects that system snapshots are not present][4]
|
||||
|
||||
![Check for Orphan Packages][5]
|
||||
|
||||
![Status before upgrade][6]
|
||||
|
||||
![Mint Upgrade can detect the packages that require a downgrade][7]
|
||||
|
||||
最后，我们成功地将一个测试系统从 LMDE 4 升级到 LMDE 5。
|
||||
|
||||

|
||||
|
||||
#### 如何获得这个升级工具
|
||||
|
||||
使用下面的命令，该工具的安装很简单。但正如该团队所建议的，它现在处于 BETA 状态，所以不要用它来进行严肃的升级。
|
||||
|
||||
```
|
||||
|
||||
sudo apt update
|
||||
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
sudo apt install mintupgrade
|
||||
|
||||
```
|
||||
|
||||
### 结束语
|
||||
|
||||
最后，我认为这是 Linux Mint 团队的最好的工具之一。正如你在上面看到的，它自己处理了许多错误。我所做的只是点击“修复”按钮。而这个工具足够聪明，能够理解所有的故障点，并负责补救。
|
||||
|
||||
[mintupgrade 工具][9]将在 Linux Mint 21 “Vanessa” 发布前发布，大约在 2022 年第三季度末或第四季度初。
