如果一个系统管理员花费大量的时间解决问题以及做重复的工作，你就应该怀疑他这么做是否正确。换句话说，一个高效的系统管理员/工程师应该制定一个计划使得尽量花费少的时间去做重复的工作，以及通过使用该系列中第三部分 [使用 Linux 工具集监视系统活动报告][1] 介绍的工具预见问题。因此，尽管看起来他/她没有做很多的工作，但那是因为 shell 脚本帮助完成了他的/她的大部分任务，这也就是本章我们将要探讨的东西。

### 什么是 shell 脚本？ ###
|
||||
|
||||
简单的说，shell 脚本就是一个由 shell 一步一步执行的程序，而 shell 是在 Linux 内核和端用户之间提供接口的另一个程序。

### 安卓1.0——谷歌系app和实体硬件的引入 ###
|
||||
|
||||
到了2008年10月，安卓1.0已经准备好发布，这个系统在[T-Mobile G1][1]（又以HTC Dream为人周知）上初次登台。G1进入了被iPhone 3G和[Nokia 1680 classic][2]所主宰的市场。（这些手机并列获得了2008年[销量最佳手机][3]称号，各自卖出了350万台。）G1的销量数字已难以获得，但T-Mobile宣称截至2009年4月该设备的销量突破了100万台。无论从哪方面来说这在竞争中都处于落后地位。

|
||||
|
||||
G1拥有单核528Mhz的ARM 11处理器，一个Adreno 130的GPU，192MB内存，以及多达256MB的存储空间供给系统以及应用使用。它有一块3.2英寸，320x480分辨率的显示屏，被布置在一个含有实体全键盘的滑动结构之上。所以尽管安卓软件的确走过了很长的一段路，硬件也是的。时至今日，我们可以在厂商的一个手表中得到比这更好的参数：最新的[三星智能手表][4]拥有512MB内存以及1GHz的双核处理器。

当iPhone有着最少数量的按键的时候，G1确实完全相反的，按键几乎支持每个硬件控制。它有拨通和挂断按钮，home键，后退，以及菜单键，一个相机快门键，音量控制键，一个轨迹球，当然，还有50个键盘按钮。未来安卓设备将会慢慢离开按键多多的界面设计，几乎每部新旗舰都在减少按键的数量。

|
||||
|
||||
但是这是第一次，人们见到了运行在实机上的安卓，而不是跑在一个令人沮丧的慢吞吞的模拟器上。安卓1.0没有iPhone那样顺滑流畅，闪亮耀眼，或拥有那么多的新闻报道。它也不像Windows Mobile 6.5那样才华横溢。但这仍然是个好的开始。

安卓1.0的核心与两个月前发布的beta版本相比看起来并没有什么引人注目的不同，但消费者产品带来了不少应用，包括一套完整的谷歌系应用。日历，电子邮件，Gmail，即时通讯，市场，设置，语音拨号，以及YouTube都是全新登场。那时候，音乐是智能手机上占据主宰地位的媒体类型，其王者是iTunes音乐商店。谷歌没有自家的音乐服务，所以它选择了亚马逊并绑定了亚马逊MP3商店。

安卓最重要的新增是谷歌商店的首次登场，叫做“安卓市场Beta”。与此同时大部分公司满足于将它们的软件目录称作一些不同的“应用商店”——意思是一个出售应用的商店，并且只出售应用——谷歌明显有着更大的野心。它搭配了一个更为通用的名字，“安卓市场”。这个名字的想法是安卓市场不仅仅拥有应用，还拥有一切你的安卓设备所需要的东西。

那时候，安卓市场只提供应用和游戏，开发者们甚至还不能为它们收费。苹果的App Store相对与安卓市场有4个月的先发优势，但是谷歌的主要差异化在于安卓的商店几乎是完全开放的。在iPhone上，应用受制于苹果的审查，必须遵循设计和技术指南。潜在的新应用不允许在功能上复制已有应用。在安卓市场，开发者可以自由地做任何想做的，包括开发替代已有的应用。控制的缺失会转变成祝福同时也是诅咒。它允许开发者革新已有的功能，但同时意味着甚至是毫无价值的垃圾应用也被允许进入市场。

Great Open Source Collaborative Editing Tools
|
||||
================================================================================
|
||||
In a nutshell, collaborative writing is writing done by more than one person. There are benefits and risks of collaborative working. Some of the benefits include a more integrated / co-ordinated approach, better use of existing resources, and a stronger, united voice. For me, the greatest advantage is one of the most transparent. That's when I need to take colleagues' views. Sending files back and forth between colleagues is inefficient, causes unnecessary delays and leaves people (i.e. me) unhappy with the whole notion of collaboration. With good collaborative software, I can share notes, data and files, and use comments to share thoughts in real-time or asynchronously. Working together on documents, images, video, presentations, and tasks is made less of a chore.

5 best open source board games to play online
|
||||
================================================================================
|
||||
I have always had a fascination with board games, in part because they are a device of social interaction, they challenge the mind and, most importantly, they are great fun to play. In my misspent youth, myself and a group of friends gathered together to escape the horrors of the classroom, and indulge in a little escapism. The time provided an outlet for tension and rivalry. Board games help teach diplomacy, how to make and break alliances, bring families and friends together, and learn valuable lessons.

LinuxCon's surprise keynote speaker Linus Torvalds muses about open-source software
|
||||
================================================================================
|
||||
> In a broad-ranging question and answer session, Linus Torvalds, Linux's founder, shared his thoughts on the current state of open source and Linux.
|
||||
|
||||
**SEATTLE** -- [LinuxCon][1] attendees got an early Christmas present when the Wednesday morning "surprise" keynote speaker turned out to be Linux's founder, Linus Torvalds.
|
||||
|
||||
|
||||
|
||||
Jim Zemlin and Linus Torvalds shooting the breeze at LinuxCon in Seattle. -- sjvn
|
||||
|
||||
Jim Zemlin, the Linux Foundation's executive director, opened the question and answer session by quoting from a recent article about Linus, "[Torvalds may be the most influential individual economic force][2] of the past 20 years. ... Torvalds has, in effect, been as instrumental in retooling the production lines of the modern economy as Henry Ford was 100 years earlier."
|
||||
|
||||
Torvalds replied, "I don't think I'm all that powerful, but I'm glad to get all the credit for open source." For someone who's arguably been more influential on technology than Bill Gates, Steve Jobs, or Larry Ellison, Torvalds remains amusingly modest. That's probably one reason [Torvalds, who doesn't suffer fools gladly][3], remains the unchallenged leader of Linux.
|
||||
|
||||
It also helps that he doesn't take himself seriously, except when it comes to code quality. Zemlin reminded him that he was also described in the same article as being "5-feet, ho-hum tall with a paunch, ... his body type and gait resemble that of Tux, the penguin mascot of Linux." Torvald's reply was to grin and say "What is this? A roast?" He added that 5'8" was a perfectly good height.
|
||||
|
||||
More seriously, Zemlin asked Torvalds what he thought about the current excitement over containers. Indeed, at times LinuxCon has felt like DockerCon. Torvalds replied, "I'm glad that the kernel is far removed from containers and other buzzwords. We only care about just the kernel. I'm so focused on the kernel I really don't care. I don't get involved in the politics above the kernel and I'm really happy that I don't know."
|
||||
|
||||
Moving on, Zemlin asked Torvalds what he thought about the demand from the Internet of Things (IoT) for an even smaller Linux kernel. "Everyone has always wished for a smaller kernel," Torvalds said. "But, with all the modules it's still tens of MegaBytes in size. It's shocking that it used to fit into a MB. We'd like it to be mean lean, mean IT machine again."
|
||||
|
||||
But, "Torvalds continued, "It's hard to get rid of unnecessary fat. Things tend to grow. Realistically I don't think we can get down to the sizes we were 20 years ago."
|
||||
|
||||
As for security, the next topic, Torvalds said, "I'm at odds with the security community. They tend to see technology as black and white. If it's not security they don't care at all about it." The truth is "security is bugs. Most of the security issues we've had in the kernel hasn't been that big. Most of them have been really stupid and then some clever person takes advantage of it."
|
||||
|
||||
The bottom line is, "We'll never get rid of bugs so security will never be perfect. We do try to be really careful about code. With user space we have to be very strict." But, "Bugs happen and all you can do is mitigate them. Open source is doing fairly well, but anyone who thinks we'll ever be completely secure is foolish."
|
||||
|
||||
Zemlin concluded by asking Torvalds where he saw Linux ten years from now. Torvalds replied that he doesn't look at it this way. "I'm plodding, pedestrian, I look ahead six months, I don't plan 10 years ahead. I think that's insane."
|
||||
|
||||
Sure, "companies plan ten years, and their plans use open source. Their whole process is very forward thinking. But I'm not worried about 10 years ahead. I look to the next release and the release beyond that."
|
||||
|
||||
For Torvalds, who works at home where "the FedEx guy is no longer surprised to find me in my bathrobe at 2 in the afternoon," looking ahead a few months works just fine. And so do all the businesses -- both technology-based Amazon, Google, Facebook and more mainstream, WalMart, the New York Stock Exchange, and McDonalds -- that live on Linux every day.

> Mark Shuttleworth, founder of Canonical and Ubuntu, made a surprise visit at LinuxCon. I sat down with him for a video interview and talked about Ubuntu on IBM’s new LinuxONE systems, Canonical’s plans for containers, open source in the enterprise space and much more.
|
||||
|
||||
### You made a surprise entry during the keynote. What brought you to LinuxCon? ###
|
||||
|
||||
**Mark Shuttleworth**: I am here at LinuxCon to support IBM and Canonical in their announcement of Ubuntu on their new Linux-only super-high-end mainframe LinuxONE. These are the biggest machines in the world, purpose-built to run only Linux. And we will be bringing Ubuntu to them, which is a real privilege for us and is going to be incredible for developers.

|

### Only Red Hat and SUSE were supported on it. Why was Ubuntu missing from the mainframe scene? ###
|
||||
|
||||
**Mark**: Ubuntu has always been about developers. It has been about enabling the free software platform from where it is collaboratively built to be available at no cost to developers in the world, so they are limited only by their imagination—not by money, not by geography.
|
||||
|
||||
There was an incredible story told today about a 12-year-old kid who started out with Ubuntu; there are incredible stories about people building giant businesses with Ubuntu. And for me, being able to empower people, whether they come from one part of the world or another to express their ideas on free software, is what Ubuntu is all about. It's been a journey for us essentially, going to the platforms those developers care about, and just in the last year, we suddenly saw a flood of requests from companies who run mainframes, who are using Ubuntu for their infrastructure—70% of OpenStack deployments are on Ubuntu. Those same people said, “Look, there is the mainframe, and we like to unleash it and think of it as a region in the cloud.” So when IBM started talking to us, saying that they have this project in the works, it felt like a very natural fit: You are going to be able to take your Ubuntu laptop, build code there and ship it straight to every cloud, every virtualization environment, every bare metal in every architecture including the mainframe, and that's going to be beautiful.
|
||||
|
||||
### Will Canonical be offering support for these systems? ###
|
||||
|
||||
**Mark**: Yes. Ubuntu on z Systems is going to be completely supported. We will make long-term commitments to that. The idea is to bring together scale-out-fast cloud-like workloads, which is really born on Ubuntu; 70% of workloads on Amazon and other public clouds run on Ubuntu. Now you can think of running that on a mainframe if that makes sense to you.
|
||||
|
||||
We are going to provide exactly the same platform that we do on the cloud, and we are going to provide that on the mainframe as well. We are also going to expose it to the OpenStack API so you can consume it on a mainframe with exactly the same tools and exactly the same processes that you would consume on a laptop, or OpenStack or public cloud resources. So all of the things that Ubuntu builds to make your life easy as a developer are going to be available across that full range of platforms and systems, and all of that is commercially supported.
|
||||
|
||||
### Canonical is doing a lot of things: It is into enterprise, and it’s in the consumer space with mobile and desktop. So what is the core focus of Canonical now? ###
|
||||
|
||||
**Mark**: The trick for us is to enable the reuse of specifically the same parts [of our technology] in as many useful ways as possible. So if you look at the work that we do at z Systems, it's absolutely defined by the work that we do on the cloud. We want to deliver exactly the same libraries on exactly the same date for the mainframe as we do for public clouds and for x86, ARM and Power servers today.
|
||||
|
||||
We don't allow Ubuntu or our focus to fragment very dramatically because we don't allow different products managers to find Ubuntu in different ways in different environments. We just want to bring that standard experience that developers love to this new environment.
|
||||
|
||||
Similarly if you look at the work we are doing on IoT [Internet of Things], Snappy Ubuntu is the heart of the phone. It’s the phone without the GUI. So the definitions, the tools, the kernels, the mechanisms are shared across those projects. So we are able to multiply the impact of the work. We have an incredible community, and we try to enable the community to do things that they want to do that we can’t do. So that's why we have so many buntus, and it's kind of incredible for me to see what they do with that.
|
||||
|
||||
We also see the community climbing in. We see hundreds of developers working with Snappy for IoT, and we see developers working with Snappy on mobile, for personal computing as convergence becomes real. And, of course, there is the cloud server story: 70% of the world is Ubuntu, so there is a huge audience. We don't have to do all the work that we do; we just have to be open and willing to, kind of, do the core infrastructure and then reuse it as efficiently as possible.
|
||||
|
||||
### Is Snappy a response to Atomic or CoreOS? ###
|
||||
|
||||
**Mark**: Snappy as a project was born four years ago when we started working on the phone, which was long before the CoreOS, long before Atomic. I think the principles of atomicity, transactionality are beautiful, but remember: We needed to build the same things for the phone. And with Snappy, we have the ability to deliver transactional updates to any of these systems—phones, servers and cloud devices.
|
||||
|
||||
Of course, it feels a little different because in order to provide those guarantees, we have to shape the system in such a way that we can guarantee the guarantees. And that's why Snappy is snappy; it's a new thing. It's not based on an old packaging system. Though we will keep both of them: All Snaps for us that Canonical makes, the core snaps that define the OS, are all built from Debian packages. They are two different faces of the same coin for us, and developers will use them as tools. We use the right tools for the job.
|
||||
|
||||
There are couple of key advantages for Snappy over CoreOS and Atomic, and the main one is this: We took the view that we wanted the base idea to be extensible. So with Snappy, the core operating system is tiny. You make all the choices, and you take all the decisions about things you want to bolt on that: you want to bolt on Docker; you want to bolt on Kubernete; you want to bolt on Mesos; you want to bolt on Lattice from Pivotal; you want to bolt on OpenStack. Those are the things you choose to add with Snappy. Whereas with Atomic and CoreOS, it's one blob and you have to do it exactly the way they want you to do it. You have to live with the versions of software and the choices they make.
|
||||
|
||||
Whereas with Snappy, we really preserve this idea of the choices you have got in Ubuntu are now transactionally available on Snappy systems. That makes the core much smaller, and it gives you the choice of different container systems, different container management systems, different cloud infrastructure systems or different apps of every description. I think that's the winning idea. In fullness of time, people will realize that they wanted to make those choices themselves; they just want Canonical to do the work of providing the updates in a really efficient manner.
|
||||
|
||||
### There is so much competition in the container space with Docker, Rocket and many other players. Where will Canonical stand amid this competition? ###
|
||||
|
||||
**Mark**: Canonical is focused on platform tools, and we see things like the Rocket and Docker as things super-useful for developers; we just make sure that those work best on Ubuntu. Docker, for years, ran only Ubuntu because we work very closely with them, and we are glad now that it's available everywhere else. But if you look at the numbers, the vast majority of Docker containers are on Ubuntu. Because we work really hard, as developers, you get the best experience with all of these tools on Ubuntu. We don't want to try and control everything, and it’s great for us to have those guys competing.
|
||||
|
||||
I think in the end people will see that there is really two kinds of containers. 1) There are cases where a container is just like a VM machine. It feels like a whole machine, it runs all processes, all the logs and cron jobs are there. It's like a VM, just that it's much cheaper, much lighter, much faster, and that's LXD. 2) And then there would be process containers, which are like Docker or Rocket; they are there to run a specific application very fast. I think we lead the world in general machine container story, which is our hypervisor LXD, and I think Docker leads the story when it comes to applications containers, process containers. And those two work together really beautifully.
|
||||
|
||||
### Microsoft and Canonical are working together on LXD? Can you tell us about this engagement? ###
|
||||
|
||||
Mark: LXD is two things. First, it's an implementation on top of Canonical's work on the kernel so that you can start to create full machine containers on any host. But it's also a REST API. That’s the transitions from LXC to LXD. We got a daemon there so you can talk to the daemon over the network, if it's listening on the network, and says tell me about the containers on that machine, tell me about the file systems on that machine, the networks on that machine, start or stop the container.
|
||||
|
||||
So LXD becomes a distributed hypervisor effectively. Very interestingly, last week Microsoft announced that they like REST API. It is very clean, very simple, very well engineered, and they are going to implement the same API for Windows machines. It's completely cross-platform, which means you will be able to talk to any machine—Linux or Windows. So it gives you very clean and simple APIs to talk about containers on any host on the network.
|
||||
|
||||
Of course, we have led the work in [OpenStack to bind LXD to Nova][1], which is the control system to compute in OpenStack, so that's how we create a whole cloud with OpenStack API with the individual VMs being actually containers, so much denser, much faster, much lighter, much cheaper.
|
||||
|
||||
### Open Source is becoming a norm in the enterprise segment. What do you think is driving the adoption of open source in the enterprise? ###
|
||||
|
||||
**Mark**: The reason why open source has become so popular in the enterprise is because it enables them to go faster. We are all competing at some level, and if you can't make progress because you have to call up some vendor, you can't dig in and help yourself go faster, then you feel frustrated. And given the choice between frustration and at least the ability to dig into a problem, enterprises over time will always choose to give themselves the ability to dig in and help themselves. So that is why open source is phenomenal.
|
||||
|
||||
I think it goes a bit deeper than that. I think people have started to realize as much as we compete, 99% of what we need to do is shared, and there is something meaningful about contributing to something that is shared. As I have seen Ubuntu go from something that developers love, to something that CIOs love that developers love Ubuntu. As that happens, it's not a one-way ticket. They often want to say how can we help contribute to make this whole thing go faster.
|
||||
|
||||
We have always seen a curve of complexity, and open source has traditionally been higher up on the curve of complexity and therefore considered threatening or difficult or too uncertain for people who are not comfortable with the complexity. What's wonderful to me is that many open source projects have identified that as a blocker for their own future. So in Ubuntu we have made user experience, design and “making it easy” a first-class goal. We have done the same for OpenStack. With Ubuntu tools for OpenStack anybody can build an OpenStack cloud in an hour, and if you want, that cloud can run itself, scale itself, manage itself, can deal with failures. It becomes something you can just fire up and forget, which also makes it really cheap. It also makes it something that's not a distraction, and so by making open source easier and easier, we are broadening its appeal to consumers and into the enterprise and potentially into the government.
|
||||
|
||||
### How open are governments to open source? Can you tell us about the utilization of open source by governments, especially in the U.S.? ###
|
||||
|
||||
**Mark**: I don't track the usage in government, but part of government utilization in the modern era is the realization that how untrustworthy other governments might be. There is a desire for people to be able to say, “Look, I want to review or check and potentially self-build all the things that I depend on.” That's a really important mission. At the end of the day, some people see this as a game where maybe they can get something out of the other guy. I see it as a game where we can make a level playing field, where everybody gets to compete. I have a very strong interest in making sure that Ubuntu is trustworthy, which means the way we build it, the way we run it, the governance around it is such that people can have confidence in it as an independent thing.
|
||||
|
||||
### You are quite vocal about freedom, privacy and other social issues on Google+. How do you see yourself, your company and Ubuntu playing a role in making the world a better place? ###
|
||||
|
||||
**Mark**: The most important thing for us to do is to build confidence in trusted platforms, platforms that are freely available but also trustworthy. At any given time, there will always be people who can make arguments about why they should have access to something. But we know from history that at the end of the day, due process of law, justice, doesn't depend on the abuse of privacy, abuse of infrastructure, the abuse of data. So I am very strongly of the view that in the fullness of time, all of the different major actors will come to the view that their primary interest is in having something that is conceptually trustworthy. This isn't about what America can steal from Germany or what China can learn in Russia. This is about saying we’re all going to be able to trust our infrastructure; that's a generational journey. But I believe Ubuntu can be right at the center of people's thinking about that.

The Free Software Foundation: 30 years in
|
||||
================================================================================
|
||||
|
||||
|
||||
Welcome back, folks, to a new Six Degrees column. As usual, please send your thoughts on this piece to the comment box and your suggestions for future columns to [my inbox][1].
|
||||
|
||||
Now, I have to be honest with you all, this column went a little differently than I expected.
|
||||
|
||||
A few weeks ago when thinking what to write, I mused over the notion of a piece about the [Free Software Foundation][2] celebrating its 30 year anniversary and how relevant and important its work is in today's computing climate.
|
||||
|
||||
To add some meat I figured I would interview [John Sullivan][3], executive director of the FSF. My plan was typical of many of my pieces: thread together an interesting narrative and quote pieces of the interview to give it color.
|
||||
|
||||
Well, that all went out the window when John sent me a tremendously detailed, thoughtful, and descriptive interview. I decided therefore to present it in full as the main event, and to add some commentary throughout. Thus, this is quite a long column, but I think it paints a fascinating picture of a fascinating organization. I recommend you grab a cup of something delicious and settle in for a solid read.
|
||||
|
||||
### The sands of change ###
|
||||
|
||||
The Free Software Foundation was founded in 1985. To paint a picture of what computing was like back then, the [Amiga 1000][4] was released, C++ was becoming a dominant language, [Aldus PageMaker][5] was announced, and networking was just starting to grow. Oh, and that year [Careless Whisper][6] by Wham! was a major hit.
|
||||
|
||||
Things have changed a lot in 30 years. Back in 1985 the FSF was primarily focused on building free pieces of software that were primarily useful to nerdy computer people. These days we have software, services, social networks, and more to consider.
|
||||
|
||||
I first wanted to get a sense of what John feels are most prominent risks to software freedom today.
|
||||
|
||||
"I think there's widespread agreement on the biggest risks for computer user freedom today, but maybe not on the names for them."
|
||||
|
||||
"The first is what we might as well just call 'tiny computers everywhere.' The free software movement has succeeded to the point where laptops, desktops, and servers can run fully free operating systems doing anything users of proprietary systems can do. There are still a few holes, but they'll be closed. The challenge that remains in this area is to cut through the billion dollar marketing budgets and legal regimes working against us to actually get the systems into users hands."
|
||||
|
||||
"However, we have a serious problem on the set of computers whose primary common trait is that they are very small. Even though a car is not especially small, the computers in it are, so I include that form factor in this category, along with phones, tablets, glasses, watches, and so on. While these computers often have a basis in free software—for example, using the kernel Linux along with other free software like Android or GNU—their primary uses are to run proprietary applications and be shims for services that replace local computing with computing done on a server over which the user has no control. Since these devices serve vital functions, with some being primary means of communication for huge populations, some sitting very close to our bodies and our actual vital functions, some bearing responsibility for our physical safety, it is imperative that they run fully free systems under their users' control. Right now, they don't."
|
||||
|
||||
John feels the risk here is not just the platforms and form factors, but the services integrates into them.
|
||||
|
||||
"The services many of these devices talk to are the second major threat we face. It does us little good booting into a free system if we do our actual work and entertainment on companies' servers running software we have no access to at all. The point of free software is that we can see, modify, and share code. The existence of those freedoms even for nontechnical users provides a shield that prevents companies from controlling us. None of these freedoms exist for users of Facebook or Salesforce or Google Docs. Even more worrisome, we see a trend where people are accepting proprietary restrictions imposed on their local machines in order to have access to certain services. Browsers—including Firefox—are now automatically installing a DRM plugin in order to appease Netflix and other video giants. We need to work harder at developing free software decentralized replacements for media distribution that can actually empower users, artists, and user-artists, and for other services as well. For Facebook we have GNU social, pump.io, Diaspora, Movim, and others. For Salesforce, we have CiviCRM. For Google Docs, we have Etherpad. For media, we have GNU MediaGoblin. But all of these projects need more help, and many services don't have any replacement contenders yet."
|
||||
|
||||
It is interesting that John mentions finding free software equivalents for common applications and services today. The FSF maintains a list of "High Priority Projects" that are designed to fill this gap. Unfortunately the capabilities of these projects varies tremendously and in an age where social media is so prominent, the software is only part of the problem: the real challenge is getting people to use it.
|
||||
|
||||
This all begs the question of where the FSF fit in today's modern computing world. I am a fan of the FSF. I think the work they do is valuable and I contribute financially to support it too. They are an important organization for building an open computing culture, but all organizations need to grow, adjust, and adapt, particularly ones in the technology space.
|
||||
|
||||
I wanted to get a better sense of what the FSF is doing today that it wasn't doing at it's inception.
|
||||
|
||||
"We're speaking to a much larger audience than we were 30 years ago, and to a much broader audience. It's no longer just hackers and developers and researchers that need to know about free software. Everyone using a computer does, and it's quickly becoming the case that everyone uses a computer."
|
||||
|
||||
John went on to provide some examples of these efforts.
|
||||
|
||||
"We're doing coordinated public advocacy campaigns on issues of concern to the free software movement. Earlier in our history, we expressed opinions on these things, and took action on a handful, but in the last ten years we've put more emphasis on formulating and carrying out coherent campaigns. We've made especially significant noise in the area of Digital Restrictions Management (DRM) with Defective by Design, which I believe played a role in getting iTunes music off DRM (now of course, Apple is bringing DRM back with Apple Music). We've made attractive and useful introductory materials for people new to free software, like our [User Liberation animated video][7] and our [Email Self-Defense Guide][8].
|
||||
|
||||
We're also endorsing hardware that [respects users' freedoms][9]. Hardware distributors whose devices have been certified by the FSF to contain and require only free software can display a logo saying so. Expanding the base of free software users and the free software movement has two parts: convincing people to care, and then making it possible for them to act on that. Through this initiative, we encourage manufacturers and distributors to do the right thing, and we make it easy for users who have started to care about free software to buy what they need without suffering through hours and hours of research. We've certified a home WiFi router, 3D printers, laptops, and USB WiFi adapters, with more on the way.
|
||||
|
||||
We're collecting all of the free software we can find in our [Free Software Directory][10]. We still have a long way to go on this—we're at only about 15,500 packages right now, and we can imagine many improvements to the design and function of the site—but I think this resource has great potential for helping users find the free software they need, especially users who aren't yet using a full GNU/Linux system. With the dangers inherent in downloading random programs off the Internet, there is a definite need for a curated collection like this. It also happens to provide a wealth of machine-readable data of use to researchers.
|
||||
|
||||
We're acting as the fiscal sponsor for several specific free software projects, enabling them to raise funds for development. Most of these projects are part of GNU (which we continue to provide many kinds of infrastructure for), but we also sponsor [Replicant][11], a fully free fork of Android designed to give users the free-est mobile devices currently possible.
|
||||
|
||||
We're helping developers use free software licenses properly, and we're following up on complaints about companies that aren't following the terms of the GPL. We help them fix their mistakes and distribute properly. RMS was in fact doing similar work with the precursors of the GPL very early on, but it's now an ongoing part of our work.
|
||||
|
||||
Most of the specific things the FSF does now it wasn't doing 30 years ago, but the vision is little changed from the original paperwork—we aim to create a world where everything users want to do on any computer can be done using free software; a world where users control their computers and not the other way around."
|
||||
|
||||
### A cult of personality ###
|
||||
|
||||
There is little doubt in anyone's minds about the value the FSF brings. As John just highlighted, its efforts span not just the creation and licensing of free software, but also recognizing, certifying, and advocating a culture of freedom in technology.
|
||||
|
||||
The head of the FSF is the inimitable Richard M. Stallman, commonly referred to as RMS.
|
||||
|
||||
RMS is a curious character. He has demonstrated an unbelievable level of commitment to his ideas, philosophy, and ethical devotion to freedom in software.
|
||||
|
||||
While he is sometimes mocked online for his social awkwardness, be it things said in his speeches, his bizarre travel requirements, or other sometimes cringeworthy moments, RMS's perspectives on software and freedom are generally rock-solid. He takes a remarkably consistent approach to his perspectives and he is clearly a careful thinker about not just his own thoughts but the wider movement he is leading. My only criticism is that I think from time to time he somewhat over-eggs the pudding with the voracity of his words. But hey, given his importance in our world, I would rather take an extra egg than no pudding for anyone. O.K., I get that the whole pudding thing here was strained...
|
||||
|
||||
So RMS is a key part of the FSF, but the organization is also much more than that. There are employees, a board, and many contributors. I was curious to see how much of a role RMS plays these days in the FSF. John shared this with me.
|
||||
|
||||
"RMS is the FSF's President, and does that work without receiving a salary from the FSF. He continues his grueling global speaking schedule, advocating for free software and computer user freedom in dozens of countries each year. In the course of that, he meets with government officials as well as local activists connected with all varieties of social movements. He also raises funds for the FSF and inspires many people to volunteer."
|
||||
|
||||
"In between engagements, he does deep thinking on issues facing the free software movement, and anticipates new challenges. Often this leads to new articles—he wrote a 3-part series for Wired earlier this year about free software and free hardware designs—or new ideas communicated to the FSF's staff as the basis for future projects."
|
||||
|
||||
As we delved into the cult of personality, I wanted to tap John's perspectives on how wide the free software movement has grown.
|
||||
|
||||
I remember being at the [Open Source Think Tank][12] (an event that brings together execs from various open source organizations) and there was a case study where attendees were asked to recommend license choice for a particular project. The vast majority of break-out groups recommended the Apache Software License (APL) over the GNU Public License (GPL).
|
||||
|
||||
This stuck in my mind as since then I have noticed that many companies seem to have opted for open licenses other than the GPL. I was curious to see if John had noticed a trend towards the APL as opposed to the GPL.
|
||||
|
||||
"Has there been? I'm not so sure. I gave a presentation at FOSDEM a few years ago called 'Is Copyleft Being Framed?' that showed some of the problems with the supposed data behind claims of shifts in license adoption. I'll be publishing an article soon on this, but here's some of the major problems:
|
||||
|
||||
|
||||
- Free software license choices do not exist in a vacuum. The number of people choosing proprietary software licenses also needs to be considered in order to draw the kinds of conclusions that people want to draw. I find it much more likely that lax permissive license choices (such as the Apache License or 3-clause BSD) are trading off with proprietary license choices, rather than with the GPL.
|
||||
- License counters often, ironically, don't publish the software they use to collect that data as free software. That means we can't inspect their methods or reproduce their results. Some people are now publishing the code they use, but certainly any that don't should be completely disregarded. Science has rules.
|
||||
- What counts as a thing with a license? Are we really counting an app under the APL that makes funny noises as 1:1 with GNU Emacs under GPLv3? If not, how do we decide which things to treat as equals? Are we only looking at software that actually works? Are we making sure not to double- and triple- count programs that exist on multiple hosting sites, and what about ports for different OSes?
|
||||
|
||||
The question is interesting to ponder, but every conclusion I've seen so far has been extremely premature in light of the actual data. I'd much rather see a survey of developers asking about why they chose particular licenses for their projects than any more of these attempts to programmatically ascertain the license of programs and then ascribe human intentions on to patterns in that data.
|
||||
|
||||
Copyleft is as vital as it ever was. Permissively licensed software is still free software and on-face a good thing, but it is contingent and needs an accompanying strong social commitment to not incorporate it in proprietary software. If free software's major long-term impact is enabling businesses to more efficiently make products that restrict us, then we have achieved nothing for computer user freedom."
|
||||
|
||||
### Rising to new challenges ###
|
||||
|
||||
30 years is an impressive time for any organization to be around, and particularly one with such important goals that span so many different industries, professions, governments, and cultures.
|
||||
|
||||
As I started to wrap up the interview I wanted to get a better sense of what the FSF's primary function is today, 30 years after the mission started.
|
||||
|
||||
"I think the FSF is in a very interesting position of both being a steady rock and actively pushing the envelope."
|
||||

"We have core documents like the [Free Software Definition][13], the [GNU General Public License][14], and the [list we maintain of free and nonfree software licenses][15], which have been keystones in the construction of the world of free software we have today. People place a great deal of trust in us to stay true to the principles outlined in those documents, and to apply them correctly and wisely in our assessments of new products or practices in computing. In this role, we hold the ladder for others to climb. As a 501(c)(3) charity held legally accountable to the public interest, and about 85% funded by individuals, we have the right structure for this."
|
||||
|
||||
"But we also push the envelope. We take on challenges that others say are too hard. I guess that means we also build ladders? Or maybe I should stop with the metaphors."
|
||||
|
||||
While John may not be great with metaphors (like I am one to talk), the FSF is great at setting a mission and demonstrating a devout commitment to it. This mission starts with a belief that free software should be everywhere.
|
||||
|
||||
"We are not satisfied with the idea that you can get a laptop that works with free software except for a few components. We're not satisfied that you can have a tablet that runs a lot of free software, and just uses proprietary software to communicate with networks and to accelerate video and to take pictures and to check in on your flight and to call an Über and to.. Well, we are happy about some such developments for sure, but we are also unhappy about the suggestion that we should be fully content with them. Any proprietary software on a system is both an injustice to the user and inherently a threat to users' security. These almost-free things can be stepping stones on the way to a free world, but only if we keep our feet moving."
|
||||
|
||||
In the early years of the FSF, we actually had to get a free operating system written. This has now been done by GNU and Linux and many collaborators, although there is always more software to write and bugs to fix. So while the FSF does still sponsor free software development in specific areas, there are thankfully many other organizations also doing this."
|
||||
|
||||
A key part of the challenge John is referring to is getting the right hardware into the hands of the right people.
|
||||
|
||||
"What we have been focusing on now are the challenges I highlighted in the first question. We are in desperate need of hardware in several different areas that fully supports free software. We have been talking a lot at the FSF about what we can do to address this, and I expect us to be making some significant moves to both increase our support for some of the projects already out there—as we having been doing to some extent through our Respects Your Freedom certification program—and possibly to launch some projects of our own. The same goes for the network service problem. I think we need to tackle them together, because having full control over the mobile components has great potential for changing how we relate to services, and decentralizing more and more services will in turn shape the mobile components."
|
||||
|
||||
I hope folks will support the FSF as we work to grow and tackle these challenges. Hardware is expensive and difficult, as is making usable, decentralized, federated replacements for network services. We're going to need the resources and creativity of a lot of people. But, 30 years ago, a community rallied around RMS and the concept of copyleft to write an entire operating system. I've spent my last 12 years at the FSF because I believe we can rise to the new challenges in the same way."
|
||||
|
||||
### Final thoughts ###
|
||||
|
||||
In reading John's thoughtful responses to my questions, and in knowing various FSF members, the one sense that resonates for me is the sheer level of passion that is alive and kicking in the FSF. This is not an organization that has got bored or disillusioned with its mission. Its passion and commitment is as voracious as it has ever been.
|
||||
|
||||
While I don't always agree with the FSF and I sometimes think its approach is a little one-dimensional at times, I have been and will continue to be a huge fan and supporter of its work. The FSF represent the ethical heartbeat of much of the free software and open source work that happens across the world. It represents a world view that is pretty hard to the left, but I believe its passion and conviction helps to bring people further to the right a little closer to the left too.
|
||||
|
||||
Sure, RMS can be odd, somewhat hardline, and a little sensational, but he is precisely the kind of leader that is valuable in a movement that encapsulates a mixture of technology, ethics, and culture. We need an RMS in much the same way we need a Torvalds, a Shuttleworth, a Whitehurst, and a Zemlin. These different people bring together mixture of perspectives that ultimately maps to technology that can be adaptable to almost any set of use cases, ethics, and ambitions.
|
||||
|
||||
So, in closing, I want to thank the FSF for its tremendous efforts, and I wish the FSF and its fearless leaders, one Richard M. Stallman and one John Sullivan, another 30 years of fighting the good fight. Go get 'em!

Italy's Ministry of Defense to Drop Microsoft Office in Favor of LibreOffice
|
||||
================================================================================
|
||||
>**LibreItalia's Italo Vignoli [reports][1] that the Italian Ministry of Defense is about to migrate to the LibreOffice open-source software for productivity and adopt the Open Document Format (ODF), while moving away from proprietary software products.**
|
||||
|
||||
The movement comes in the form of a [collaboration][1] between Italy's Ministry of Defense and the LibreItalia Association. Sonia Montegiove, President of the LibreItalia Association, and Ruggiero Di Biase, Rear Admiral and General Executive Manager of Automated Information Systems of the Ministry of Defense in Italy signed an agreement for a collaboration to adopt the LibreOffice office suite in all of the Ministry's offices.
|
||||
|
||||
While the LibreItalia non-profit organization promises to help the Italian Ministry of Defense with trainers for their offices across the country, the Ministry will start the implementation of the LibreOffice software on October 2015 with online training courses for their staff. The entire transition process is expected to be completed by the end of year 2016\. An Italian law lets officials find open source software alternatives to well-known commercial software.
|
||||
|
||||
"Under the agreement, the Italian Ministry of Defense will develop educational content for a series of online training courses on LibreOffice, which will be released to the community under Creative Commons, while the partners, LibreItalia, will manage voluntarily the communication and training of trainers in the Ministry," says Italo Vignoli, Honorary President of LibreItalia.
|
||||
|
||||
### The Ministry of Defense will adopt the Open Document Format (ODF)
|
||||
|
||||
The initiative will allow the Italian Ministry of Defense to be independent from proprietary software applications, which are aimed at individual productivity, and adopt open source document format standards like Open Document Format (ODF), which is used by default in the LibreOffice office suite. The project follows similar movements already made by governments of other European countries, including United Kingdom, France, Spain, Germany, and Holland.
|
||||
|
||||
It would appear that numerous other public institutions all over Italy are using open source alternatives, including the Italian Region Emilia Romagna, Galliera Hospital in Genoa, Macerata, Cremona, Trento and Bolzano, Perugia, the municipalities of Bologna, ASL 5 of Veneto, Piacenza and Reggio Emilia, and many others. AGID (Agency for Digital Italy) welcomes this project and hopes that other public institutions will do the same.

A Slick New Set-Up Wizard Is Coming To Ubuntu and Ubuntu Touch
|
||||
================================================================================
|
||||
> Canonical aims to 'seduce and reassure' those unfamiliar with the OS by making a good first impression
|
||||
|
||||
**The Ubuntu installer is set to undergo a dramatic makeover.**
|
||||
|
||||
Ubuntu will modernise its out-of-the-box experience (OOBE) to be easier and quicker to complete, look more ‘seductive’ to new users, and better present the Ubuntu brand through its design.
|
||||
|
||||
Ubiquity, the current Ubuntu installer, has largely remained unchanged since its [introduction back in 2010][1].
|
||||
|
||||
### First Impressions Are Everything ###
|
||||
|
||||
Since the first thing most users see when trying Ubuntu for the first time is an installer (or set-up wizard, depending on device) the design team feel it’s “one of the most important categories of software usability”.
|
||||
|
||||
“It essentially says how easy your software is to use, as well as introducing the user into your brand through visual design and tone of voice, which can convey familiarity and trust within your product.”
|
||||
|
||||
Canonical’s new OOBE designs show a striking departure from the current look of the Ubiquity installer used by the Ubuntu desktop, and presents a refined approach to the way mobile users ‘set up’ a new Ubuntu Phone.
|
||||
|
||||
|
||||
|
||||
Old design (left) and the new proposed design
|
||||
|
||||
Detailing the designs in [new blog post][2], the Canonical Design team say the aim of the revamp is to create a consistent out-of-the-box experience across Ubuntu devices.
|
||||
|
||||
To do this it groups together “common first experiences found on the mobile, tablet and desktop” and unifies the steps and screens between each, something they say moves the OS closer to “achieving a seamless convergent platform.”
|
||||
|
||||
|
||||
|
||||
New Ubuntu installer on desktop/tablet (left) and phone
|
||||
|
||||
Implementation of the new ‘OOBE’ has already begun’ according to Canonical, though as of writing there’s no firm word on when a revamped installer may land on either desktop or phone images.
|
||||
|
||||
With the march to ‘desktop’ convergence now in full swing, and a(nother) stack of design changes set to hit the mobile build in lieu of the first Ubuntu Phone that ‘transforms’ in to a PC, chances are you won’t have to wait too long to try it out.
|
||||
|
||||
**What do you think of the designs? How would you go about improving the Ubuntu set-up experience? Let us know in the comments below.**

Ubuntu 15.10, Codenamed Wily Werewolf, Review
|
||||
================================================================================
|
||||
|
||||
|
||||
The problem we have with reviewing Ubuntu on any occasion, is readers consistently expect to read of a revolutionary new release, every 6 months. If you’re expecting Ubuntu 15.10 to be just that, then you may want to click out of this review right now. It’s important to clarify that this is nothing negative towards 15.10 as a release, but it is a maintenance release and not a release which purports to introduce a great deal of new software.
|
||||
|
||||
With that opening disclaimer out of the way, let’s take a look at what 15.10 does offer.
|
||||
|
||||
### Linux kernel 4.2 ###
|
||||
|
||||
The biggest change you will find with Ubuntu 15.10 is the kernel branch has been upgraded to **Linux 4.2**.
|
||||
|
||||
This is long overdue for Ubuntu. It feels like it has been lagging behind other distributions by sticking with the 3.x branch of Linux for the entirety of the 15.04 cycle.
|
||||
|
||||
If you’re going to be installing Ubuntu 15.10 on new hardware, then you will benefit greatly from the Linux kernel upgrade to 4.x branch as there is loads of updates which directly improve performance on new hardware. Support for AMDGPU kernel DRM is included, which is a boon for owners of recent Radeon graphics cards. The latest iteration of the driver will reside alongside the current Radeon DRM drivers, which was already in the kernel in addition to the usual open-source driver offerings.
|
||||
|
||||
Support for Intel Broxton is also included in Linux 4.2, albeit Ubuntu 15.10 users are probably going to get nothing out of this update, yet it’s still worthy of a mention we think. There are also some erroneous updates for Skylake CPU’s. Finally, there is a host of code updates and fixes for Ext4 filesystems.
|
||||
|
||||
That pretty much rounds out the Linux kernel 4.2 updates. So what else is new? Let’s take a closer look at the software that you may be more familiar with and get more excited about.
|
||||
|
||||
### Software ###
|
||||
|
||||
LibreOffice has been upgraded to 5.0.1.2, a major update for LibreOffice users. Firefox on the version that we tested is sitting at 41.0.2. By the time you read this, it will most-likely be updated again and you may see a newer version be pushed out through the Ubuntu Repositories.
|
||||
|
||||
On the desktop front, a vanilla Ubuntu installation will see you running Unity 7.3.2 while GNOME sits at 3.8. On the KDE end, a Plasma 5 desktop will see you running version 5.4.2. For the alternative desktop-environments, XFCE has been upgraded to the latest revision, 4.12 while the version of MATE includes 1.10.
|
||||
|
||||
### User Experience/Screenshots ###
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
Ubuntu 15.10 as a operating system for Review is pretty lackluster. There’s nothing new as such and there’s nothing we can really say that is going to change your opinion from its predecessor, 15.04. Therefore, we recommend you to upgrade either out of habit and according to your regular upgrade schedule rather than out of a specific necessity for a specific feature of this release. Because there is really nothing that could possibly differentiate it from the older, yet still very stable 15.04 release. But if you’re going to stick with 15.04 for a little longer, we do recommend that you look at [upgrading the kernel to the latest 4.2 branch][2]. It is worth it.
|
||||
|
||||
If you really want a reason to upgrade? Linux kernel 4.2 would be our sole reason for taking Ubuntu 15.10 into consideration.
|
||||
|
||||
### Looking Ahead ###
|
||||
|
||||
What we really look forward to is the release of Ubuntu 16.04. We have been promised over and over again for several releases that Mir will be the default display server included in Ubuntu. We still see releases pushed out that rely on X.org. It has resulted in us adopting a “yeah right” attitude as we have become accustomed to the usual delay announcements.
|
||||
|
||||
We are hopeful that Mir Developers can push out a working version in time for the release of 16.04 next year. As precaution though, we urge you to not get too excited because it may very well not happen.
|
||||
|
||||
It remains much the same with Unity 8. It’s most certainly a possibility, but we can’t guarantee that it will be included in 16.04, yet we remain hopeful.
|
||||
|
||||
As we’ve mentioned for this release, there’s nothing really ground-breaking with this release. In fact, it has been much the same story for the last couple of releases of Ubuntu Linux. It is in dire need of a distribution-wide reboot. Developers and Ubuntu users alike are positive that Mir and Unity 8 will be the two primary packages that may just provide the popular, yet ailing, distribution the reboot that it needs.

10 Things To Do After Installing Ubuntu 15.10 'Wily Werewolf'
|
||||
================================================================================
|
||||
|
||||
|
||||
Yesterday Ubuntu 15.10 was made [available to download][1] with some new features, improvements and updated apps. If you've upgraded to Ubuntu 15.10 then this article is going to show you 10 things/tweaks that you need to do to make your Ubuntu more handy and fruitful.
|
||||
|
||||
### What's New In Ubuntu 15.10? ###
|
||||
|
||||
Ubuntu 15.10 codenamed 'Wily Werewolf' was released yesterday with new features, improvements, fixes and updated apps. Read our complete article to know more stuff added with Ubuntu 15.10.
|
||||
|
||||
### Things To Do After Installing Ubuntu 15.10 ###
|
||||
|
||||
Ubuntu 15.10 is shipping with new features that are activated by default, no need to tweak for anyone. But, changes made in the last release of Ubuntu 15.04, were not activated by default and so in Ubuntu 15.10. Other than those changes you need to install useful/must have applications. So first tweak our newly installed Wily Werewolf.
|
||||
|
||||
### 1. Update Ubuntu 15.10 ###
|
||||
|
||||
Before you use the system and any app first check for updates. Updating the system is necessary to keep the OS more stable and secure. Updates also adds new features in the system. Although there won't be larger size of updates after you within some days of release as all the packages are already to their newest versions.
|
||||
|
||||
|
||||
|
||||
#### Tweak Ubuntu 15.10 ####
|
||||
|
||||
One of things to notice is that the tweaks that were presented in the last Ubuntu release are not activated by default. Those are still at your wish, if you want go ahead and activate them. For example, Always Show Menus, Where to show menu, in the window's title bar or in the menu bar.
|
||||
|
||||
### 2. Set Menus Position ###
|
||||
|
||||
By default in Ubuntu 15.10, the menu are set to show in the menu bar which is sometimes uneasy to reach to but you can set the menus to show in the window's title bar. Go to **Settings >> Appearances >> Behavior >> in the window's title bar**.
|
||||
|
||||
|
||||
|
||||
3. Install Unity Tweak Tool
|
||||
|
||||
To tweak system more install Unity Tweak Tool, It has more options than the default system settings. You can change theme, icons, workspaces settings and many more. Check the screenshot below -
|
||||
|
||||
|
||||
|
||||
### 4. Install Firewall To Block Harmful Incoming/Outgoing Connections ###
|
||||
|
||||
|
||||
|
||||
One of the favorite ways of hackers to get access to individuals' system is to scan for the open ports and attack through them. A firewall protect your system from such attacks by blocking harmful incoming/outgoing connections.
|
||||
|
||||
UFW stands ofr Uncomplicated Firewall. As the name suggests it's the most easy to use firewall you ever used. Just install and switch it on. Configure firewall rules, block particular ports etc. easily. To know all about UFW and how to use all of its features read our following article -
|
||||
|
||||
[Install UFW Firewall In Linux And Secure Computer From Harmful Incoming/Outgoing Connections][2]
|
||||
|
||||
#### Install UFW Firewall ####
|
||||
|
||||
$ sudo apt-get install ufw
|
||||
Install Graphical Interface
|
||||
$ sudo apt-get install gufw
|
||||
|
||||
### 5. Install Graphics Drivers ###
|
||||
|
||||
If you're a game lover or you play HD videos or do video editing kind of things then you need to have proprietary drivers installed available for your hardware for better graphics performance.
|
||||
|
||||
To install graphics driver -
|
||||
|
||||
Go to **Settings >> Software & Updates >> Additional Drivers**
|
||||
|
||||
It will search for the latest drivers available for you hardware.
|
||||
|
||||
|
||||
|
||||
### 6. Install VLC & Media Codecs For More Media Support ###
|
||||
|
||||
VLC supports most file formats so it's better to use VLC to escape the error while playing audio files.
|
||||
|
||||
Sometimes you play a mp3 and it does not play. To solve this problem, Ubuntu gives an option while you're installing Ubuntu to install all the necessary media codecs. If you checked that then don't worry, if you haven't then do the following -
|
||||
|
||||
$ sudo apt-get install vlc
|
||||
Install Media Codecs
|
||||
$ sudo apt-get install ubuntu-restricted-extras
|
||||
|
||||
### 7. Configure Cloud Storage ###
|
||||
|
||||
Cloud storage are very useful to share files across your local devices like, Mobile to PC or Laptops and vice-versa. User can easily install Storages like, Dropbox, Copy, Gdrive (Using Grive) etc.
|
||||
|
||||
#### Dropbox ####
|
||||
|
||||
To install Dropbox, download Dropbox installation client first.
|
||||
|
||||
- [Download Dropbox][3]
|
||||
|
||||
Download Dropbox for your system architecture. To check whether your system is 64-Bit or 32-Bit
|
||||
|
||||
Goto **Settings >> Details**
|
||||
|
||||
Open the downloaded .deb file with Ubuntu Software Center and click install.
|
||||
|
||||
|
||||
|
||||
When installed search Dropbox in Ubuntu dash and open it. It's just an installation client, so now this will install Dropbox app. Once the download competes you'll have the app asking for your Dropbox credentials. Enter your email id and password and login. All of your cloud files will be synced in your Ubuntu desktop.
|
||||
|
||||
### 8. Enhance Look By Installing Themes ###
|
||||
|
||||
The default two themes are not too much attractive. You can download and install cool themes from our Linux Themes Page.

|
||||
|
||||
### 9. Install & Configure Email Client ###
|
||||
|
||||
Email clients are very useful because you can check for new emails without opening up web browser. Ubuntu 15.10 comes with Thunderbird email client, one of the most popular email clients, supports multiple email accounts and desktop notifications.
|
||||
|
||||
Thunderbird is simple to configure. Just use your email id and password to login and sync your emails right into your desktop/laptop.

||||
|
||||

### 10. Take The Poll ###
|
||||

||||
================================================================================
|
||||
The stable edition of Ubuntu 15.10 wily werewolf is just released by canonical few days a ago and it now available to download and install on your computer. Lets take a look at the features that are implemented in the new release of ubuntu 15.10 and see what important packages have been updated.
|
||||
|
||||
Watch – A quick video about “What’s new in Ubuntu 15.10“, thanks to [linuxscoop][1] for making this video.

|
||||
|
||||
Below we are can mention the new features of Ubuntu 15.10 Wily Werewolf
|
||||
|
||||
### Linux kernel 4.2 ###
|
||||
|
||||
|
||||
|
||||
Ubuntu 15.10 ships with linux kernel 4.2. This introduces lots of changes, like support for the new AMD GPU driver, NCQ TRIM handling, queue spinlocks, F2FS per-file encryption and lots of new and updated drivers.
|
||||
|
||||
### Unity 7.3.2 ###
|
||||
|
||||
|
||||
|
||||
Unity as the main desktop of ubuntu 15.10 has been updated to version 7.3.2. it comes with bug fixes, polish and small usability improvements. The following we can mention the features of Unity 7.3.2:
|
||||
|
||||
- Allows drag and drop apps from the Dash to the desktop to create shortcuts
|
||||
- Page up/down keyboard navigation works as scroll in the Dash
|
||||
- Dash title & BFB tooltip is updated based on your privacy settings
|
||||
- Session exit buttons now have a click effect
|
||||
- Fix to prevent ‘shutdown’ of computer when screen is locked
|
||||
- Active app icons now show unfolded when launcher accordion triggered
|
||||
- Fix for full screen menubar
|
||||
- Fixes issues with ‘show desktop’ that caused window decoration for two windows of same app to vanish
|
||||
- Dash: Non-expandable category headers skipped in keyboard navigation
|
||||
- Dash: Non-expandable category headers are no longer highlighted on mouse over
|
||||
- Dash: screenreader and KeyNav fixes
|
||||
- New setting to control the show-now delay (when pressing Alt key)
|
||||
- Logic tweak to stop adjacent menu opening when moving from an indicator icon to its menu
|
||||
|
||||
### GNOME 3.16 stack ###
|
||||
|
||||
|
||||
|
||||
Another important changes for this release, the most of the packages from the GNOME stack updated to version 3.16.x. This is a good thing since these packages do come with lots of improvements.Unfortunately, the nautilus file manager for Ubuntu 15.10 is still in version 3.14 and Gedit text editor file still dating from 3.10.
|
||||
|
||||
### Introduce GNOME Overlay Scrollbars ###
|
||||
|
||||
|
||||
|
||||
In Ubuntu 15.10, Ubuntu developers have decided to implement the GNOME Overlay scrollbars, it replacement of Unity’s overlay scrollbars for GTK3 applications. That’s no different than before, but it does serve as a stark and regular reminder of how much easier it is to use scrollbars that are always present in a predicable spot and wider than the pinpoint tip of a mouse cursor.
|
||||
|
||||
### Ubuntu Make ###
|
||||
|
||||
|
||||
|
||||
Ubuntu Make, a command-line utility that allows you to download the latest version of popular developer tools easier on Ubuntu, now supports even more platforms, frameworks and services, including a full Android development environment.
|
||||
|
||||
### Persistent Network Interface Names ###
|
||||
|
||||
|
||||
|
||||
Ubuntu developer also introduces stateless persistent network interface names in Ubuntu 15.10. This means that naming the network interfaces like eth0 or eth1 will be a thing of the past and that new more comprehensive names will be used. Also, the names will remain valid even after a restart or if the hardware is removed.
|
||||
|
||||
### Steam Controller Support ###
|
||||
|
||||
|
||||
|
||||
In this release, Ubuntu Developer also add support for the Steam Controller in Ubuntu 15.10. For now, the updated Steam package seems to be available only for Ubuntu 15.10, but it’s possible that the patch will be backported to other supported distributions. This means that Ubuntu 15.10 users will be able to plug the new controller, open Steam, and just play without having to read and apply any kind of advice from tutorials.
|
||||
|
||||
### New Default Wallpaper ###
|
||||
|
||||
|
||||
|
||||
Ubuntu 15.10 bring a new default wallpaper, the wallpaper desaign concept adopted from origami and it called suru. A new set of community sourced wallpapers are also included.
|
||||
|
||||

Installation Guide for Puppet on Ubuntu 15.04
|
||||
================================================================================
|
||||
Hi everyone, today in this article we'll learn how to install puppet to manage your server infrastructure running ubuntu 15.04. Puppet is an open source software configuration management tool which is developed and maintained by Puppet Labs that allows us to automate the provisioning, configuration and management of a server infrastructure. Whether we're managing just a few servers or thousands of physical and virtual machines to orchestration and reporting, puppet automates tasks that system administrators often do manually which frees up time and mental space so sysadmins can work on improving other aspects of your overall setup. It ensures consistency, reliability and stability of the automated jobs processed. It facilitates closer collaboration between sysadmins and developers, enabling more efficient delivery of cleaner, better-designed code. Puppet is available in two solutions configuration management and data center automation. They are **puppet open source and puppet enterprise**. Puppet open source is a flexible, customizable solution available under the Apache 2.0 license, designed to help system administrators automate the many repetitive tasks they regularly perform. Whereas puppet enterprise edition is a proven commercial solution for diverse enterprise IT environments which lets us get all the benefits of open source puppet, plus puppet apps, commercial-only enhancements, supported modules and integrations, and the assurance of a fully supported platform. Puppet uses SSL certificates to authenticate communication between master and agent nodes.

How to switch from NetworkManager to systemd-networkd on Linux
|
||||
================================================================================
|
||||
In the world of Linux, adoption of [systemd][1] has been a subject of heated controversy, and the debate between its proponents and critics is still going on. As of today, most major Linux distributions have adopted systemd as a default init system.

How to Create New File Systems/Partitions in the Terminal on Linux
|
||||
================================================================================
|
||||
|
||||
|
||||
Partition editing or making new file systems on Linux usually means one thing: installing the Gnome Parted partition editor (GParted). For most Linux users, this is the only way to go about it. Still, what if you could edit these partitions and file systems right in the terminal? You can! Here’s how!
|
||||
|
||||
### Creating a basic Linux partition layout with CFdisk ###
|
||||
|
||||
Here’s how to make a basic Linux partition scheme right from the command line. The first thing to do is open your terminal. Once you’re there, you’ll need to identify what hard drive you’re looking to change. This can easily be figured out with one simple command.
|
||||
|
||||
lsblk
|
||||
|
||||
|
||||
|
||||
|
||||
Once you’ve run `lsblk`, you should get a detailed list of each hard drive currently on your system. Look through this generated list, and figure out the denotation to the drive you want to change. In this article I’ll be using `sdb` for the sake of example.
|
||||
|
||||
In your terminal enter this command. It will launch a powerful terminal-based partition editing program.
|
||||
|
||||
sudo cfdisk /dev/sdb
|
||||
|
||||
|
||||
|
||||
**Note**: replace `sdb` with whatever `lsblk` told you your hard drive was.
|
||||
|
||||
When this command is entered, you’ll be inside the partition editor and will have total access to the hard drive you wish to modify.
|
||||
|
||||
Since hard drive partitions are different, depending on a user’s needs, this part of the guide will go over **how to set up a split Linux home/root system layout**.
|
||||
|
||||
To start, a root partition will need to be created. This will require a bit of math as the gigabytes on the hard drive need to be divided up. My test drive is 32 GB.
|
||||
|
||||
In CFdisk using the arrow keys on your keyboard, select some free space. Once you’ve found some, use the arrow key to select [ NEW ] and press the Enter key.
|
||||
|
||||
|
||||
|
||||
The program will ask you to input the partition size. Once you’ve specified the size, press the Enter key. This will be known as the root partition (or /dev/sdb1).
|
||||
|
||||
Next it’s time to create the home partition (/dev/sdb2). Once again, you’ll need to select some free space in CFdisk. Use the arrow key to select the [ NEW ] option, and press the Enter key. Input the size of your home partition, and press the Enter key to create it.
|
||||
|
||||
|
||||
|
||||
Finally, the swap partition needs to be created. Like the two times before, find some free space, and use the arrow key to select the [ NEW ] option. After that calculate exactly how big your Linux swap partition needs to be.
|
||||
|
||||
**Note**: a swap partition is usually about as big as a computer’s physical RAM.
|
||||
|
||||
|
||||
|
||||
Now that the swap partition has been created, it’s time to specify its type. Highlight it with the up and down arrow keys. After that use the left and right arrow keys to select [ TYPE ]. Find Linux swap in the menu, and press Enter.
|
||||
|
||||
|
||||
|
||||
All of the partition creation is out of the way. All that’s left is to write it to the disk. Using the right arrow key, select the [ WRITE ] option, and press the Enter key. This will write your newly created layout directly to the hard drive.
|
||||
|
||||
### Creating file systems with mkfs ###
|
||||
|
||||
Sometimes you don’t need to make an entire partition layout. Sometimes you just need to make a file system. This can easily be accomplished directly in the terminal with the `mkfs` command.
|
||||
|
||||
|
||||
|
||||
To start, figure out what you’re looking to modify. Enter `lsblk` in your terminal to find out. It’ll print out a list, and after that just find the partition or drive you want to make a file system on.
|
||||
|
||||
In this example, I’ll point it towards the first partition of the secondary drive `/dev/sdb1`. It’s also possible to just point mkfs to `/dev/sdb` (to make use of the entire drive).
|
||||
|
||||
|
||||
|
||||
To create the new file system on a specific partition, just enter
|
||||
|
||||
sudo mkfs.ext4 /dev/sdb1
|
||||
|
||||
into the terminal. It should be noted that `mkfs.ext4` can be changed to whatever file system you want to use.
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
Though editing file systems and partitions is easier using a graphical tool, the terminal is arguably more efficient. It’s much more faster to just load up a terminal, tap a few buttons and be done. With GParted and tools like it, it’s a whole ordeal. I hope that with the help of this tutorial you, too, understand how efficient editing file systems in the terminal can be.
|
||||
|
||||
Do you prefer to use terminal-based programs to edit partitions on Linux? Why or why not? Tell us below!

How to Install Pure-FTPd with TLS on FreeBSD 10.2
|
||||
================================================================================
|
||||
FTP or File Transfer Protocol is application layer standard network protocol used to transfer file from the client to the server, after user logged in to the FTP server over the TCP-Network, such as internet. FTP has been round long time ago, much longer then P2P Program, or World Wide Web, and until this day it was a primary method for sharing file with other over the internet and it it remain very popular even today. FTP provide an secure transmission, that protect username, password and encrypt the content with SSL/TLS.
|
||||
|
||||
Pure-FTPd is free FTP Server with strong and focus on the software security. It was great choice for you if you want to provide a fast, secure, lightweight with feature rich FTP Services. Pure-FTPd can be install on variety of Unix-like operating system, include Linux and FreeBSD. Pure-FTPd is created by Frank Dennis in 2001, based on Troll-FTPd, and until now is actively developed by a team led by Dennis.
|
||||
|
||||
In this tutorial we will provide about installation and configuration of "**Pure-FTPd**" with Unix-like operating system FreeBSD 10.2.
|
||||
|
||||
### Step 1 - Update system ###
|
||||
|
||||
The first thing you must do is to install and update the freebsd repository, please connect to your server with SSH and then type command below as sudo/root :
|
||||
|
||||
freebsd-update fetch
|
||||
freebsd-update install
|
||||
|
||||
### Step 2 - Install Pure-FTPd ###
|
||||
|
||||
You can install Pure-FTPd from the ports method, but in this tutorial we will install from the freebsd repository with "**pkg**" command. So, now let's install :
|
||||
|
||||
pkg install pure-ftpd
|
||||
|
||||
Once installation is finished, please add pure-ftpd to the start at the boot time with sysrc command below :
|
||||
|
||||
sysrc pureftpd_enable=yes
|
||||
|
||||
### Step 3 - Configure Pure-FTPd ###
|
||||
|
||||
Configuration file for Pure-FTPd is located at directory "/usr/local/etc/", please go to the directory and copy the sample configuration for pure-ftpd to "**pure-ftpd.conf**".
|
||||
|
||||
cd /usr/local/etc/
|
||||
cp pure-ftpd.conf.sample pure-ftpd.conf
|
||||
|
||||
Now edit the file configuration with nano editor :
|
||||
|
||||
nano -c pure-ftpd.conf
|
||||
|
||||
Note : -c option to show line number on nano.
|
||||
|
||||
Go to line 59 and change the value of "VerboseLog" to "**yes**". This option is allow you as administrator to see the log all command used by the users.
|
||||
|
||||
VerboseLog yes
|
||||
|
||||
And now look at line 126 "PureDB" for virtual-users configuration. Virtual users is a simple mechanism to store a list of users, with their password, name, uid, directory, etc. It's just like /etc/passwd. But it's not /etc/passwd. It's a different file and only for FTP. In this tutorial we will store the list of user to the file "**/usr/local/etc/pureftpd.passwd**" and "**/usr/local/etc/pureftpd.pdb**". Please uncomment that line and change the path for the file to "/usr/local/etc/pureftpd.pdb".
|
||||
|
||||
PureDB /usr/local/etc/pureftpd.pdb
|
||||
|
||||
Next, uncomment on the line 336 "**CreateHomeDir**", this option make you easy to add the virtual users, allow automatically create home directories if they are missing.
|
||||
|
||||
CreateHomeDir yes
|
||||
|
||||
Save and exit.
|
||||
|
||||
Next, start pure-ftpd with service command :
|
||||
|
||||
service pure-ftpd start
|
||||
|
||||
### Step 4 - Adding New Users ###
|
||||
|
||||
At this step FTP server is started without error, but you can not log in to the FTP Server, because the default configuration of pure-ftpd is disabled for anonymous users. We need to create new users with home directory, and then give it the password for login.
|
||||
|
||||
On thing you must do befere you add new user to pure-ftpd virtual-user is to create a system user for this, lets create new system user "**vftp**" and the default group is same as username, with home directory "**/home/vftp/**".
|
||||
|
||||
pw useradd vftp -s /sbin/nologin -w no -d /home/vftp \
|
||||
-c "Virtual User Pure-FTPd" -m
|
||||
|
||||
Now you can add the new user for the FTP Server with "**pure-pw**" command. For an example here, we will create new user named "**akari**", so please see command below :
|
||||
|
||||
pure-pw useradd akari -u vftp -g vftp -d /home/vftp/akari
|
||||
Password: TYPE YOUR PASSWORD
|
||||
|
||||
that command will create user "**akari**" and the data stored at the file "**/usr/local/etc/pureftpd.passwd**", not at /etc/passwd file, so this means is that you can easily create FTP-only accounts without messing up your system accounts.
|
||||
|
||||
Next, you must generate the PureDB user database with this command :
|
||||
|
||||
pure-pw mkdb
|
||||
|
||||
Now restart the pure-ftpd services and try connect with user "akari" :
|
||||
|
||||
service pure-ftpd restart
|
||||
|
||||
Trying to connect with user akari :
|
||||
|
||||
ftp SERVERIP
|
||||
|
||||
|
||||
|
||||
**NOTE :**
|
||||
|
||||
If you want to add new user again, you can use "**pure-pw**" command. And if you want to delete the current user, you can use this :
|
||||
|
||||
pure-pw userdel useryouwanttodelete
|
||||
pure-pw mkdb
|
||||
|
||||
### Step 5 - Add SSL/TLS to Pure-FTPd ###
|
||||
|
||||
Pure-FTPd supports encryption using TLS security mechanisms. To support for TLS/SSL, make sure the OpenSSL library is already installed on your freebsd system.
|
||||
|
||||
Now you must generate new "**self-signed certificate**" on the directory "**/etc/ssl/private**". Before you generate the certificate, please create new directory there called "private".
|
||||
|
||||
cd /etc/ssl/
|
||||
mkdir private
|
||||
cd private/
|
||||
|
||||
Now generate "self-signed certificate" with openssl command below :
|
||||
|
||||
openssl req -x509 -nodes -newkey rsa:2048 -sha256 -keyout \
|
||||
/etc/ssl/private/pure-ftpd.pem \
|
||||
-out /etc/ssl/private/pure-ftpd.pem
|
||||
|
||||
FILL ALL WITH YOUR PERSONAL INFO.
|
||||
|
||||
|
||||
|
||||
Next, change the certificate permission :
|
||||
|
||||
chmod 600 /etc/ssl/private/*.pem
|
||||
|
||||
Once the certifcate is generated, Edit the pure-ftpd configuration file :
|
||||
|
||||
nano -c /usr/local/etc/pure-ftpd.conf
|
||||
|
||||
Uncomment on line **423** to enable the TLS :
|
||||
|
||||
TLS 1
|
||||
|
||||
And line **439** for the certificate file path :
|
||||
|
||||
CertFile /etc/ssl/private/pure-ftpd.pem
|
||||
|
||||
Save and exit, then restart the pure-ftpd services :
|
||||
|
||||
service pure-ftpd restart
|
||||
|
||||
Now let's test the Pure-FTPd that work with TLS/SSL. I'm here use "**FileZilla**" to connect to the FTP Server, and use user "**akari**" that have been created.
|
||||
|
||||
|
||||
|
||||
Pure-FTPd with TLS on FreeBSD 10.2 successfully.
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
FTP or File Transfer Protocol is standart protocol used to transfer file between users and the server. One of the best, lightweight and secure FTP Server Software is Pure-FTPd. It is secure and support for TLS/SSL encryption mechanism. Pure-FTPd is easy to to install and configure, you can manage the user with virtual user support, and it is make you as sysadmin is easy to manage the user if you have a much user ftp server.

How to Install Redis Server on CentOS 7
|
||||
================================================================================
|
||||
Hi everyone, today Redis is the subject of our article, we are going to install it on CentOS 7. Build sources files, install the binaries, create and install files. After installing its components, we will set its configuration as well as some operating system parameters to make it more reliable and faster.
|
||||
|
||||
|
||||
|
||||
Redis server
|
||||
|
||||
Redis is an open source multi-platform data store written in ANSI C, that uses datasets directly from memory achieving extremely high performance. It supports various programming languages, including Lua, C, Java, Python, Perl, PHP and many others. It is based on simplicity, about 30k lines of code that do "few" things, but do them well. Despite you work on memory, persistence may exist and it has a fairly reasonable support for high availability and clustering, which does good in keeping your data safe.
|
||||
|
||||
### Building Redis ###
|
||||
|
||||
There is no official RPM package available, we need to build it from sources, in order to do this you will need install Make and GCC.
|
||||
|
||||
Install GNU Compiler Collection and Make with yum if it is not already installed
|
||||
|
||||
yum install gcc make
|
||||
|
||||
Download the tarball from [redis download page][1].
|
||||
|
||||
curl http://download.redis.io/releases/redis-3.0.4.tar.gz -o redis-3.0.4.tar.gz
|
||||
|
||||
Extract the tarball contents
|
||||
|
||||
tar zxvf redis-3.0.4.tar.gz
|
||||
|
||||
Enter Redis the directory we have extracted
|
||||
|
||||
cd redis-3.0.4
|
||||
|
||||
Use Make to build the source files
|
||||
|
||||
make
|
||||
|
||||
### Install ###
|
||||
|
||||
Enter on the src directory
|
||||
|
||||
cd src
|
||||
|
||||
Copy Redis server and client to /usr/local/bin
|
||||
|
||||
cp redis-server redis-cli /usr/local/bin
|
||||
|
||||
Its good also to copy sentinel, benchmark and check as well.
|
||||
|
||||
cp redis-sentinel redis-benchmark redis-check-aof redis-check-dump /usr/local/bin
|
||||
|
||||
Make Redis config directory
|
||||
|
||||
mkdir /etc/redis
|
||||
|
||||
Create a working and data directory under /var/lib/redis
|
||||
|
||||
mkdir -p /var/lib/redis/6379
|
||||
|
||||
#### System parameters ####
|
||||
|
||||
In order to Redis work correctly you need to set some kernel options
|
||||
|
||||
Set the vm.overcommit_memory to 1, which means always, this will avoid data to be truncated, take a look [here][2] for more.
|
||||
|
||||
sysctl -w vm.overcommit_memory=1
|
||||
|
||||
Change the maximum of backlog connections some value higher than the value on tcp-backlog option of redis.conf, which defaults to 511. You can find more on sysctl based ip networking "tunning" on [kernel.org][3] website.
|
||||
|
||||
sysctl -w net.core.somaxconn=512.
|
||||
|
||||
Disable transparent huge pages support, that is known to cause latency and memory access issues with Redis.
|
||||
|
||||
echo never > /sys/kernel/mm/transparent_hugepage/enabled
|
||||
|
||||
### redis.conf ###
|
||||
|
||||
Redis.conf is the Redis configuration file, however you will see the file named as 6379.conf here, where the number is the same as the network port is listening to. This name is recommended if you are going to run more than one Redis instance.
|
||||
|
||||
Copy sample redis.conf to **/etc/redis/6379.conf**.
|
||||
|
||||
cp redis.conf /etc/redis/6379.conf
|
||||
|
||||
Now edit the file and set at some of its parameters.
|
||||
|
||||
vi /etc/redis/6379.conf
|
||||
|
||||
#### daemonize ####
|
||||
|
||||
Set daemonize to no, systemd need it to be in foreground, otherwise Redis will suddenly die.
|
||||
|
||||
daemonize no
|
||||
|
||||
#### pidfile ####
|
||||
|
||||
Set the pidfile to redis_6379.pid under /var/run.
|
||||
|
||||
pidfile /var/run/redis_6379.pid
|
||||
|
||||
#### port ####
|
||||
|
||||
Change the network port if you are not going to use the default
|
||||
|
||||
port 6379
|
||||
|
||||
#### loglevel ####
|
||||
|
||||
Set your loglevel.
|
||||
|
||||
loglevel notice
|
||||
|
||||
#### logfile ####
|
||||
|
||||
Set the logfile to /var/log/redis_6379.log
|
||||
|
||||
logfile /var/log/redis_6379.log
|
||||
|
||||
#### dir ####
|
||||
|
||||
Set the directory to /var/lib/redis/6379
|
||||
|
||||
dir /var/lib/redis/6379
|
||||
|
||||
### Security ###
|
||||
|
||||
Here are some actions that you can take to enforce the security.
|
||||
|
||||
#### Unix sockets ####
|
||||
|
||||
In many cases, the client application resides on the same machine as the server, so there is no need to listen do network sockets. If this is the case you may want to use unix sockets instead, for this you need to set the **port** option to 0, and then enable unix sockets with the following options.
|
||||
|
||||
Set the path to the socket file
|
||||
|
||||
unixsocket /tmp/redis.sock
|
||||
|
||||
Set restricted permission to the socket file
|
||||
|
||||
unixsocketperm 700
|
||||
|
||||
Now, to have access with redis-cli you should use the -s flag pointing to the socket file
|
||||
|
||||
redis-cli -s /tmp/redis.sock
|
||||
|
||||
#### requirepass ####
|
||||
|
||||
You may need remote access, if so, you should use a password, that will be required before any operation.
|
||||
|
||||
requirepass "bTFBx1NYYWRMTUEyNHhsCg"
|
||||
|
||||
#### rename-command ####
|
||||
|
||||
Imagine the output of the next command. Yes, it will dump the configuration of the server, so you should deny access to this kind information whenever is possible.
|
||||
|
||||
CONFIG GET *
|
||||
|
||||
To restrict, or even disable this and other commands by using the **rename-command**. You must provide a command name and a replacement. To disable, set the replacement string to "" (blank), this is more secure as it will prevent someone from guessing the command name.
|
||||
|
||||
rename-command FLUSHDB "FLUSHDB_MY_SALT_G0ES_HERE09u09u"
|
||||
rename-command FLUSHALL ""
|
||||
rename-command CONFIG "CONFIG_MY_S4LT_GO3S_HERE09u09u"
|
||||
|
||||
|
||||
|
||||
Access through unix sockets with password and command changes
|
||||
|
||||
#### Snapshots ####
|
||||
|
||||
By default Redis will periodically dump its datasets to **dump.rdb** on the data directory we set. You can configure how often the rdb file will be updated by the save command, the first parameter is a timeframe in seconds and the second is a number of changes performed on the data file.
|
||||
|
||||
Every 15 hours if there was at least 1 key change
|
||||
|
||||
save 900 1
|
||||
|
||||
Every 5 hours if there was at least 10 key changes
|
||||
|
||||
save 300 10
|
||||
|
||||
Every minute if there was at least 10000 key changes
|
||||
|
||||
save 60 10000
|
||||
|
||||
The **/var/lib/redis/6379/dump.rdb** file contains a dump of the dataset on memory since last save. Since it creates a temporary file and then replace the original file, there is no problem of corruption and you can always copy it directly without fear.
|
||||
|
||||
### Starting at boot ###
|
||||
|
||||
You may use systemd to add Redis to the system startup
|
||||
|
||||
Copy sample init_script to /etc/init.d, note also the number of the port on the script name
|
||||
|
||||
cp utils/redis_init_script /etc/init.d/redis_6379
|
||||
|
||||
We are going to use systemd, so create a unit file named redis_6379.service under **/etc/systems/system**
|
||||
|
||||
vi /etc/systemd/system/redis_6379.service
|
||||
|
||||
Put this content, try man systemd.service for details
|
||||
|
||||
[Unit]
|
||||
Description=Redis on port 6379
|
||||
|
||||
[Service]
|
||||
Type=forking
|
||||
ExecStart=/etc/init.d/redis_6379 start
|
||||
ExecStop=/etc/init.d/redis_6379 stop
|
||||
|
||||
[Install]
|
||||
WantedBy=multi-user.target
|
||||
|
||||
Now add the memory overcommit and maximum backlog options we have set before to the **/etc/sysctl.conf** file.
|
||||
|
||||
vm.overcommit_memory = 1
|
||||
|
||||
net.core.somaxconn=512
|
||||
|
||||
For the transparent huge pages support there is no sysctl directive, so you can put the command at the end of /etc/rc.local
|
||||
|
||||
echo never > /sys/kernel/mm/transparent_hugepage/enabled
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
That's enough to start, with these settings you will be able to deploy Redis server for many simpler scenarios, however there is many options on redis.conf for more complex environments. On some cases, you may use [replication][4] and [Sentinel][5] to provide high availability, [split the data][6] across servers, create a cluster of servers. Thanks for reading!

How to Install SQLite 3.9.1 with JSON Support on Ubuntu 15.04
|
||||
================================================================================
|
||||
Hello and welcome to our today's article on SQLite which is the most widely deployed SQL database engine in the world that comes with zero-configuration, that means no setup or administration needed. SQLite is public-domain software package that provides relational database management system, or RDBMS that is used to store user-defined records in large tables. In addition to data storage and management, database engine process complex query commands that combine data from multiple tables to generate reports and data summaries.
|
||||
|
||||
SQLite is very small and light weight that does not require a separate server process or system to operate. It is available on UNIX, Linux, Mac OS-X, Android, iOS and Windows which is being used in various software applications like Opera, Ruby On Rails, Adobe System, Mozilla Firefox, Google Chrome and Skype.
|
||||
|
||||
### 1) Basic Requirements: ###
|
||||
|
||||
There is are no such complex complex requirements for the installation of SQLite as it mostly comes support all major cross platforms.
|
||||
|
||||
So, let's login to your Ubuntu server with sudo or root credentials using your CLI or Secure Shell. Then update your system so that your operating system is upto date with latest packages.
|
||||
|
||||
In ubuntu, the below command is to be used for system update.
|
||||
|
||||
# apt-get update
|
||||
|
||||
If you are starting to deploy SQLite on on a fresh Ubuntu, then make sure that you have installed some basic system management utilities like wget, make, unzip, gcc.
|
||||
|
||||
To install wget, make and gcc packages on ubuntu, you use the below command, then press "Y" to allow and proceed with installation of these packages.
|
||||
|
||||
# apt-get install wget make gcc
|
||||
|
||||
### 2) Download SQLite ###
|
||||
|
||||
To download the latest package of SQLite, you can refer to their official [SQLite Download Page][1] as shown below.
|
||||
|
||||
|
||||
|
||||
You can copy the link of its resource package and download it on ubuntu server using the wget utility command.
|
||||
|
||||
# wget https://www.sqlite.org/2015/sqlite-autoconf-3090100.tar.gz
|
||||
|
||||
|
||||
|
||||
After downloading is complete, extract the package and change your current directory to the extracted SQLite folder by using the below command as shown.
|
||||
|
||||
# tar -zxvf sqlite-autoconf-3090100.tar.gz
|
||||
|
||||
### 3) Installing SQLite ###
|
||||
|
||||
Now we are going to install and configure the SQLite package that we downloaded. So, to compile and install SQLite on ubuntu run the configuration script within the same directory where your have extracted the SQLite package as shown below.
|
||||
|
||||
root@ubuntu-15:~/sqlite-autoconf-3090100# ./configure –prefix=/usr/local
|
||||
|
||||
|
||||
|
||||
Once the package is configuration is done under the mentioned prefix, then run the below command make command to compile the package.
|
||||
|
||||
root@ubuntu-15:~/sqlite-autoconf-3090100# make
|
||||
source='sqlite3.c' object='sqlite3.lo' libtool=yes \
|
||||
DEPDIR=.deps depmode=none /bin/bash ./depcomp \
|
||||
/bin/bash ./libtool --tag=CC --mode=compile gcc -DPACKAGE_NAME=\"sqlite\" -DPACKAGE_TARNAME=\"sqlite\" -DPACKAGE_VERSION=\"3.9.1\" -DPACKAGE_STRING=\"sqlite\ 3.9.1\" -DPACKAGE_BUGREPORT=\"http://www.sqlite.org\" -DPACKAGE_URL=\"\" -DPACKAGE=\"sqlite\" -DVERSION=\"3.9.1\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_DLFCN_H=1 -DLT_OBJDIR=\".libs/\" -DHAVE_FDATASYNC=1 -DHAVE_USLEEP=1 -DHAVE_LOCALTIME_R=1 -DHAVE_GMTIME_R=1 -DHAVE_DECL_STRERROR_R=1 -DHAVE_STRERROR_R=1 -DHAVE_POSIX_FALLOCATE=1 -I. -D_REENTRANT=1 -DSQLITE_THREADSAFE=1 -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_RTREE -g -O2 -c -o sqlite3.lo sqlite3.c
|
||||
|
||||
After running make command, to complete the installation of SQLite on ubuntu run the 'make install' command as shown below.
|
||||
|
||||
# make install
|
||||
|
||||
|
||||
|
||||
### 4) Testing SQLite Installation ###
|
||||
|
||||
To confirm the successful installation of SQLite 3.9, run the below command in your command line interface.
|
||||
|
||||
# sqlite3
|
||||
|
||||
You will the SQLite verion after running the above command as shown.
|
||||
|
||||
|
||||
|
||||
### 5) Using SQLite ###
|
||||
|
||||
SQLite is very handy to use. To get the detailed information about its usage, simply run the below command in the SQLite console.
|
||||
|
||||
sqlite> .help
|
||||
|
||||
So here is the list of all its available commands, with their description that you can get help to start using SQLite.
|
||||
|
||||
|
||||
|
||||
Now in this last section , we make use of few SQLite commands to create a new database using the SQLite3 command line interface.
|
||||
|
||||
To to create a new database run the below command.
|
||||
|
||||
# sqlite3 test.db
|
||||
|
||||
To create a table within the new database run the below command.
|
||||
|
||||
sqlite> create table memos(text, priority INTEGER);
|
||||
|
||||
After creating the table, insert some data using the following commands.
|
||||
|
||||
sqlite> insert into memos values('deliver project description', 15);
|
||||
sqlite> insert into memos values('writing new artilces', 100);
|
||||
|
||||
To view the inserted data from the table , run the below command.
|
||||
|
||||
sqlite> select * from memos;
|
||||
deliver project description|15
|
||||
writing new artilces|100
|
||||
|
||||
to exit from the sqlite3 type the below command.
|
||||
|
||||
sqlite> .exit
|
||||
|
||||
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
In this article you learned the installation of latest version of SQLite 3.9.1 which enables the recently JSON1 support in its 3.9.0 version and so on. Its is an amazing library that gets embedded inside the application that makes use of it to keep the resources much efficient and lighter. We hope you find this article much helpful, feel free to get back to us if you find any difficulty.

How to Setup Pfsense Firewall and Basic Configuration
|
||||
================================================================================
|
||||
In this article our focus is Pfsense setup, basic configuration and overview of features available in the security distribution of FreeBSD. In this tutorial we will run network wizard for basic setting of firewall and detailed overview of services. After the [installation process][1] following snapshot shows the IP addresses of WAN/LAN and different options for the management of Pfsense firewall.
|
||||
|
||||
|
||||
|
||||
After setup , following window appear which shows the url for configuration of Pfsense.
|
||||
|
||||
|
||||
|
||||
Open above given URL in the browser and login with username **admin** and password **pfsense**
|
||||
|
||||
|
||||
|
||||
After successful login, following wizard appears for the basic setting of Pfsense firewall. However setup wizard option can be bypassed and user can run it from the **System** menu from the web interface.
|
||||
|
||||
Click on the **Next** button to start basic configuration process on Pfsense firewall.
|
||||
|
||||
|
||||

|
||||
Next window shows setting for the WAN interface. By defaults Pfsense firewall block bogus and private networks.
|
||||
|
||||
|
||||
|
||||
Setting LAN IP address which is used to access the Pfsense web interface for further configuration.
|
||||
|
||||
|
||||
|
||||
By default password for web interface is "pfsense". Enter new password for admin user on the following window to access the web interface for further configuration.
|
||||
|
||||
|
||||
|
||||
Click on the "reload" button which is shown below. It applies the setting and redirect firewall user to main dashboard of Pfsense.

### Conclusion ###
|
||||
|
||||
In this article our focus was on the basic configuration and features set of Pfsense distribution. It is based on FreeBSD distribution and widely used due to security and stability features. In our future articles on Pfsense, our focus will be on the basic firewall rules setting, snort (IDS/IPS) and IPSEC VPN configuration.

How to Manage Your To-Do Lists in Ubuntu Using Go For It Application
|
||||
================================================================================
|
||||
|
||||
|
||||
Task management is arguably one of the most important and challenging part of professional as well as personal life. Professionally, as you assume more and more responsibility, your performance is directly related to or affected with your ability to manage the tasks you’re assigned.
|
||||
|
||||
If your job involves working on a computer, then you’ll be happy to know that there are various applications available that claim to make task management easy for you. While most of them cater to Windows users, there are many options available on Linux, too. In this article we will discuss one such application: Go For It.
|
||||
|
||||
### Go For It ###
|
||||
|
||||
[Go For It][1] (GFI) is developed by Manuel Kehl, who describes it as a “a simple and stylish productivity app, featuring a to-do list, merged with a timer that keeps your focus on the current task.” The timer feature, specifically, is interesting, as it also makes sure that you take a break from your current task and relax for sometime before proceeding further.
|
||||
|
||||
### Download and Installation ###
|
||||
|
||||
Users of Debian-based systems, like Ubuntu, can easily install the app by running the following commands in terminal:
|
||||
|
||||
sudo add-apt-repository ppa:mank319/go-for-it
|
||||
sudo apt-get update
|
||||
sudo apt-get install go-for-it
|
||||
|
||||
Once done, you can execute the application by running the following command:
|
||||
|
||||
go-for-it
|
||||
|
||||
### Usage and Configuration ###
|
||||
|
||||
Here is how the GFI interface looks when you run the app for the very first time:
|
||||
|
||||
|
||||
|
||||
As you can see, the interface consists of three tabs: To-Do, Timer, and Done. While the To-Do tab contains a list of tasks (the 4 tasks shown in the image above are there by default – you can delete them by clicking on the rectangular box in front of them), the Timer tab contains task timer, while Done contains a list of tasks that you’ve finished successfully. Right at the bottom is a text box where you can enter the task text and click “+” to add it to the list above.
|
||||
|
||||
For example, I added a task named “MTE-research-work” to the list and selected it by clicking on it in the list – see the screenshot below:
|
||||
|
||||
|
||||
|
||||
Then I selected the Timer tab. Here I could see a 25-minute timer for the active task which was “MTE-reaserch-work.”
|
||||
|
||||
|
||||
|
||||
Of course, you can change the timer value and set to any time you want. I, however, didn’t change the value and clicked the Start button present below to start the task timer. Once 60 seconds were left, GFI issued a notification indicating the same.
|
||||
|
||||
|
||||
|
||||
And once the time was up, I was asked to take a break of five minutes.
|
||||
|
||||
|
||||
|
||||
Once those five minutes were over, I could again start the task timer for my task.
|
||||
|
||||
|
||||
|
||||
When you’re done with your task, you can click the Done button in the Timer tab. The task is then removed from the To-Do tab and listed in the Done tab.
|
||||
|
||||
|
||||
|
||||
GFI also allows you to tweak some of its settings. For example, the settings window shown below contains options to tweak the default task duration, break duration, and reminder time.
|
||||
|
||||
|
||||
|
||||
It’s worth mentioning that GFI stores the to-do lists in the Todo.txt format which simplifies synchronization with mobile devices and makes it possible for you to edit tasks using other frontends – read more about it [here][2].
|
||||
|
||||
You can also see the GFI app in action in the video below.
|
||||
|
||||
注：youtube 视频

||||

|
||||
|
||||
### Conclusion ###
|
||||
|
||||
As you have observed, GFI is an easy to understand and simple to use task management application. Although it doesn’t offer a plethora of features, it does what it claims – the timer integration is especially useful. If you’re looking for a basic, open-source task management tool for Linux, Go For It is worth trying.

用Linux学习：使用这些Linux应用来征服你的数学
|
||||
================================================================================
|
||||
|
||||
|
||||
这篇文章是[用Linux学习][1]系列的一部分:
|
||||
|
||||
- [用Linux学习: 学习类型][2]
|
||||
- [用Linux学习: 物理模拟][3]
|
||||
- [用Linux学习: 学习音乐][4]
|

- [用Linux学习: 两个地理应用程序][5]
|
||||
- [用Linux学习: 用这些Linux应用来征服你的数学][6]
|
||||
|
||||
|
||||
Linux提供了大量的教育软件和许多优秀的工具来帮助所有年龄段的学生学习和练习各种各样的话题,常常以交互的方式。与Linux一起学习这一系列的文章则为这些各种各样的教育软件和应用提供了一个介绍。
|
||||
|
||||
数学是计算机的核心。如果有人用精益求精和纪律来预期一个伟大的操作系统，比如GNU/ Linux，那么这将是数学。如果你在寻求一些数学应用程序，那么你将不会感到失望。Linux提供了很多优秀的工具使得数学看起来和你曾经做过的一样令人畏惧，但实际上他们会简化你使用它的方式。
|
||||
### Gnuplot ###
|
||||
|
||||
Gnuplot 是一个适用于不同平台的命令行脚本化和多功能的图形工具。尽管它的名字，并不是GNU操作系统的一部分。也没有免费授权，但它是免费软件（这意味着它受版权保护，但免费使用）。
|
||||
|
||||
要在Ubuntu系统（或者衍生系统）上安装 `gnuplot`，输入：
|
||||
sudo apt-get install gnuplot gnuplot-x11
|
||||
|
||||
进入一个终端窗口。启动该程序，输入：
|
||||
|
||||
gnuplot
|
||||
|
||||
你会看到一个简单的命令行界面：
|
||||
|
||||
|
||||
|
||||
在其中您可以直接开始输入函数。绘图命令将绘制一个曲线图。
|
||||
|
||||
输入内容，例如，
|
||||
|
||||
plot sin(x)/x
|
||||
|
||||
随着`gnuplot的`提示，将会打开一个新的窗口，图像便会在里面呈现。
|
||||
|
||||
|
||||
|
||||
你也可以在线这个图设置不同的属性，比如像这样指定“title”
|
||||
|
||||
plot sin(x) title 'Sine Function', tan(x) title 'Tangent'
|
||||
|
||||
|
||||
|
||||
使用`splot`命令，你可以给的东西更深入一点并且绘制3D图形
|
||||
|
||||
splot sin(x*y/20)
|
||||
|
||||
|
||||
|
||||
这个窗口有几个基本的配置选项,
|
||||
|
||||
|
||||
|
||||
但是`gnuplot`的真正力量在于在它的命令行和脚本功能，`gnuplot`广泛完整的文档可在这里找到，并在[Duke大学网站][8]上面看见这个了不起的教程[7]的原始版本。
|
||||
|
||||
### Maxima ###
|
||||
|
||||
[Maxima][9]是从Macsyma原始资料开发的一个计算机代数系统，根据它的 SourceForge 页面，
|
||||
|
||||
> “Maxima是符号和数值的表达，包括微分，积分，泰勒级数，拉普拉斯变换，常微分方程，线性方程组，多项式，集合，列表，向量，矩阵和张量系统的操纵系统。Maxima通过精确的分数，任意精度的整数和可变精度浮点数产生高精度的计算结果。Maxima可以二维和三维中绘制函数和数据。“
|
||||
|
||||
你将会获得二进制包用于大多数Ubuntu衍生系统的Maxima以及它的图形界面中，插入所有包，输入：
|
||||
|
||||
sudo apt-get install maxima xmaxima wxmaxima
|
||||
|
||||
在终端窗口中，Maxima是一个没有太多UI的命令行工具，但如果你开始wxmaxima，你会进入一个简单但功能强大的图形用户界面。
|
||||
|
||||
|
||||
|
||||
你可以开始输入这个来简单的一个开始。（提示：如果你想计算一个表达式，使用“Shift + Enter”回车后会增加更多的方法）
|
||||
|
||||
Maxima可以用于一些简单的问题，因此也可以作为一个计算器，
|
||||
|
||||
|
||||
|
||||
以及一些更复杂的问题,
|
||||
|
||||
|
||||
|
||||
它使用`gnuplot`使得绘制简单,
|
||||
|
||||
|
||||
|
||||
或者绘制一些复杂的图形.
|
||||
|
||||
|
||||
|
||||
（它需要gnuplot-X11的包，来显示它们。）
|
||||
|
||||
除了美化一些图形，Maxima也尽可能用latex格式导出它们，或者通过右键是捷菜单进行一些突出的操作.
|
||||
|
||||
|
||||
|
||||
然而其主菜单还是提供了大量压倒性的功能，当然Maxima的功能远不止如此，这里也有一个广泛使用的在线文档。
|
||||
|
||||
### 总结 ###
|
||||
|
||||
数学不是一个简单的学科，这些在Linux上的优秀软件也没有使得数学更加简单，但是这些应用使得使用数学变得更加的简单和工程化。以上两种应用都只是介绍一下Linux的所提供的。如果你是认真从事数学和需要更多的功能与丰富的文档，那你更应该看看这些Mathbuntu项目。
