+================================================================================ +![](http://www.linuxinsider.com/images/rw661226/linux-enterprise-proprietary-code.jpg) + +> 对于一些产业来讲，在开源的Linux发行版上运行专属（proprietary）软件并不是个例，--相反这很常见。例如，在华尔街，“华尔街上百分之九十九的应用依赖于专属软件。在那些运行在Linux上而有专属许可证的产品中，Oracle是我们非常喜欢的一款”， FSMLabs 的总裁 Victor Yodaiken这样说。 + +迁移到Linux平台并不是一个非此即彼的提议。linux作为一个灵活开放的计算平台为用户在软件选择上提供了更多的选项。 + +第一个方法是Linux的桌面环境，个人计算用户，小型办公室和企业都可以从众多的企业级Linux发行版中选择。在Windows和被限定在其昂贵硬件的基于unix的苹果OS X之外，Linux桌面系统为用户提供了另外一种零成本或者低成本的选择。 + +另一个迁移的办法是，让员工放弃Linux桌面办公，取而代之，企业可以在Linux服务器上运行后台办公系统。在网络应用和云计算领域遍布Linux的足迹，Linux服务器能在各种企业设定中寻找到自己的位置。 + +第三个方法是运行一个完整的Linux商店，常用的办公计算、网上浏览、图片编辑工作软件都存放在开源的软件包中。开源的数据库程序连接着后台的软件和服务器，而且Linux不需要特殊的硬件和多余的花销。 + +培训员工使用Linux桌面应用仅需要很少的投入。这要感谢职员们对跨平台软件的熟悉，例如LibreOffice 和 Open Office, 当然还有 google Chrome和 Firefox浏览器。先前的办公交流工具真的面临着威胁。 + +Linux很灵活。一种新的趋势是编写第三方的特定软件来满足自己的商业需求，商业软件公司可以重新编译打包那些必备的windows或者其他平台的软件。他们也可以结合开源的组件用他们自己特定的代码来编写特定需求的linux应用程序。 + +Dayan Jeremiah，[Icewarp Pacific][1]的CEO告诉linuxinsider：“我相信这将是一个新的趋势，企业正在使用可以运行在Linux系统上的第三方软件。让企业走向定制化软件的一个因素就是购买微软授权的经济负担太重。” + +### Linux 上运行专属软件 ### + +很多公司转向其他操作系统面临的问题就是软件和应用程序的兼容性问题，比如转向Linux，那么这家企业必须保证它用的软件必须是兼容Linux操作系统的，jeremiah补充道。 + +Linux操作系统有着数量巨大的软件，它们运行在数量众多的linux发行版和桌面环境当中。考虑到行业的特殊性，广大的开源团体或许并没有提供替代一个特定计算任务的替代品。这样的情况下，就不得不花费精力寻找第三方软件开发者的帮助。 + + “通过第三方厂商帮助来保证兼容性的问题，比如，我们可以混合和匹配各种软件组件在一起，以便让一个应用程序可以运行在Linux上。”jeremiah这样说。 + +### 旧貌换新颜 ### + +越来越多的专属软件公司，比如Icewarp，开发特定的软件来满足企业特定的业务需求，他们将许多开源组件混合在一起使用。 + +相比在微软框架下，这样不仅节约了授权费用，也节省了开发代码的费用。 + +“我们可以使用现成的软件组件为Linux构建完整的软件解决方案，这个方案非常节省，高效而且稳定。”jeremiah补充道。 + +Icewarp开发的特定软件并不是免费的开源项目，并不提供免费版本，需要订购并支付费用，而且售后支持也是收费的。 + +### 代码移植的混乱 ### + +[Lucera][2]的CEO Jacob Loveless提到，把一个来自其它平台的软件变成Linux兼容的，一个很大的障碍就是Linux的多样性。Linux操作系统有一个通用的内核，但是不同的发行版有很多不同的特点。 + +“当软件公司不得不在多个Linux系统中交叉编译时，问题进一步加深。”除了微软的Exchange数据库之外（LCTT译注：此处疑为笔误，可能是“MS SQL Server”），大部分数据库都在linux上运行的很好，MySQL和PostSQL是其中非常出名的两个开源软件（LCTT译注：此处PostSQL应该是Postgresql）。” + +在软件移植到Linux时的最大挑战，是需要重新编译代码，通常你必须要完成一些平台特定的修改才能让它工作，他说。 + +比如，你有特定的基于.Net的代码或者其他的针对Windows的语言代码，Linux上开源的编译器并不总是兼容，所以你有很多的软件工作必须重做，loveless解释说。 + +另外一个例子就是数据库，你往往不得不改用其他的数据库或者不同的网页服务器。 + + “这确实需要一些工作”loveless说道。 + +### 多但不足够 ### + +另外一个转向Linux的兼容性问题就是公司需要的开源软件类型。 + + “对于公司特定的计算需求开源软件方案并不完善”ICeWarp的Jeremiah补充说“但是，通常对于Linux来说都是足够的，开源团体无法做到的特定的应用程序可以由第三方来实现。” 比如说，IceWarp最近完成的一个特定的Linux兼容的应用程序就不需要采购额外的硬件也没产生多余的授权费用。 + +这个特定的软件包含一个负载均衡的集群，一个运行数据库的集群，另外一个是IP服务器的集群。所有的都运行在RHEL或者CentOS linux发行版当中。 + +### 跟钱走！ ### + +在一些情况下，有钱才有Linux操作系统的应用，有时候Linux服务器在一个领域很流行，又有些时候只是一个特定的Linux桌面应用程序，有时候两者都有。 + +举个例子，例如在华尔街，在金融市场中时间同步是关键。金融网络依靠分布式网络，用户必须在截止时间内完成交易。其它的应用需要在交易前进行精确的计时。[FSMLabs][3] 的总裁 Victor Yodaiken 说，这些功能需要精确的时间同步控制。 + +当FSMLabs开始开发时间同步软件时，Yodaiken觉得他们只需要开发一个Windows版本。 + +然而，事实证明每一个在使用自动交易或者高频交易的人，甚至以高精度采集数据的人，都运行的是Linux系统，他告诉LinuxInsider。 + +### 惜时如金 ### + +FSMLabs在Linux上运行他们的专属代码，Linux上的互联网时间协议（NTP）并不适用于同步时间在纳秒级别的应用，比如那些追踪股票变动，或者交易需求。 windows的不足有另一个原因。 + +Yodaiken说道：“（在这方面，）Linux比Windows流行是因为windows没有一个标准的API可以让你在毫秒级之下获取时间，所以Window并不是真的都好，你必须得有特定的API才行。而在Linux下。你不需要在你的应用程序上费力了。” + +金融市场是第一个拥抱Linux的，很多早期的系统管理员来自20世纪80年代的[贝尔实验室][4]，因此这是一个很成熟的市场，他补充到。 + +### 满足需求 ### + +在某些领域，在开源的Linux发行版上运行有专利的软件并不意外，这是很常见的。 + +“华尔街99%的应用都运行在有专利的产品上。在我们在Linux上运行的有专属许可证的产品中，我们很喜欢Oracle。”FSMLab 的 Yodaiken说。 + +一些使用Linux的市场需要更多特定的软件，现有的开源软件并不能满足他们，这就是为什么软件开发者们为企业Linux应用提供了商业的解决方案。他补充道。 + + “这很平常，开源软件很适合大的市场，这就是为什么他有广泛而且通用的需求，不是很多人需要绝对的微秒级的时间，而且如果没有市场就会发出信号。”他指出。 + +### Linux纯粹主义是没有意义的 ### + +在Linux上运行完全免费开源的软件的观念是欠缺的，有时候你要运行专属软件。对于任何特定的行业都是这样。 + +当一个专业的计算不需要进入广泛市场时，第三方的软件开发者可以提供特定的，商业的或者闭源的软件解决方案。由于商业需求不断进入Linux系统，绝对的开源将成为过去的事情。 + +“在Linux上拥有商业软件是相当普遍的”，Yodaiken说，“商人都不是纯粹主义者，他们只想解决问题。” + +Jack M.Genmain从Apple II和PC时代就开始报道电脑科技，他还有原始的IBM PC-Jr和运行DOS的机器。他留着共享软件和开源软件的linux桌面。他运行着好几种版本的Windows和Linux，经常不能决定是用他的tablet还是netbook还是android智能机，而不是用他的桌面电脑或者笔记本。你可以在google+上联系他。 + +

Additionally, a set of Diffie-Hellman parameters can be generated for better protection of the session keys. The length of the pregenerated DH parameters can be chosen in the web interface,” also noted the devs. - -According to the changelog, the cipher that is used for each net-to-net connection can now be changed, the hash function is now configurable with a few options like SHA2 (512, 384, and 256-bit), Whirpool (512 bit), and SHA1 (160 bit), and the tls-auth option can be enabled, which uses a HMAC function. - -The Linux kernel used by the distribution has also been updated in this release and the OS now packs the 3.10.44 version. This should bring support for new hardware, a number of security fixes, and more stability. - -Also, snort (the Intrusion Detection System) has been updated to version 2.9.6.1, the new firewall GUI now supports blocking access to the GREEN firewall interface, the PIE packet scheduler has been added, and the default size of the root partition has been increased. - -The developers recommend all users of IPFire to upgrade their distributions.

ARM does not manufacture its own processors, licensing its designs to chip manufacturers instead. + +A standard implementation would mean that customers could purchase ARMv8-A servers from any manufacturer, knowing that their ARM 64-bit operating systems and software will work no matter who created the chip, Coggin said. Red Hat would like Linux ARM to avoid the fate of AT&T's Unix operating system, which fragmented into a number of different and incompatible versions. + +"We see the importance of stepping in early and ensure that we don't end up with a fragmented approach, where if you wanted to run an AMD implementation of ARM, you'd need one version of Linux, and if you wanted to run a Broadcom implementation of ARM, you'd need another version," Coggin said. + +Some of the work of standardizing ARM for servers has been done through an industry consortium started earlier this year, called the [Server Base System Architecture][3] (SBSA) specification, as well as through ongoing work from the Linaro Enterprise Group. Red Hat's unnamed ARM Linux distribution uses specifications from both groups. + +Red Hat hopes to influence not only the companies that make the chips but also hardware vendors, original equipment manufacturers and original design manufacturers. + +Thus far, manufacturers such as Advanced Micro Devices, American Megatrends, AppliedMicro, Broadcom, Cavium, Dell and Hewlett-Packard have all pledged support to Red Hat's standardization efforts. + +"If ARM is to be a viable competitor in the server space, [hardware providers] have to comply to the common understanding of what is possible to run on this type of server. Customers and users demand that from manufacturers today in the x86 world," said Yan Fisher, Red Hat technical product marketing manager. + +Through the program, Red Hat will learn more about what the manufacturers need from an enterprise Linux distribution for 64-bit ARM, Coggin said. The operating system may one day become the basis for an ARM version of RHEL. + +"We're trying to understand the platform dependencies from a technology requirements perspective," Coggin said. "We don't know if or when this will ever become a product, but we are positioning ourselves in a way that at some point we could enter the market." + +Red Hat's Fedora project has offered an ARM distribution for the past several years and this release, though based on the Fedora work, is configured more toward ARM server use. + +Although ARM processors are used in most mobile devices, only recently [has there been a movement in the industry][4] to use them in data-center servers as well, where their low-power design could cut energy costs. + +Only a handful of ARMv8-A processors and associated hardware are currently available, mostly as early previews for developers or packaged in proprietary systems. + +AMD Opteron A1100-Series ARM processors, designed specifically for servers, were released Wednesday to developers. AMD also offers the ARM Cortex-A57 ARMv8 which was designed for system-on-a-chip architectures. + +AppliedMicro offers production-ready ARM servers, under the X-Gene brand and Hewlett-Packard is prepping its Moonshot line of ARM servers.

Since then more powerful, better connected or cheaper boards have come onto the market, but the Pi retains its position as the white knight of ICT teaching. - -Why? Because of the community of users that has grown up around it. To find out more we travelled west to Manchester, venue for the second annual Jamboree – a festival of educators, makers and messer-abouters focussed on highlighting how engaging the Pi can be. There, we met 75% of the Raspberry Pi Foundation’s education team – Ben Nuttall, Clive Beale and Carrie Anne Philbin – to discuss IT teaching in the UK. - -![](http://www.linuxvoice.com/wp-content/uploads/pi-top-img-4.jpg) - -**LV**: So, Raspberry Pi education team, we were saying earlier that the obvious place to start is with the UK government’s Year of Code initiative, but that seems far too negative to being with! - -**Carrie Anne**: Yeah, but there’s so much to say about it! - -**Clive**: I think it’s a fantastic initiative, which just represents everything we stand for, blah, blah, blah, blah, blah! - -**LV**: Should we just leave that then? - -**Clive**: I mean the main issue is how the media portray computing, which is a brilliant, creative, rigorous, hard, challenging, fun thing, to just reduced to ‘this code’. ‘We must learn to code.’ ‘You better learn code or you’re a rubbish teacher.’ Which of course is not the case at all, it’s so much more than that. And so the teachers are running around now thinking the sky’s falling because they think that by September 2014, if they can’t code, then they’ve failed and they’ll think their kids have failed, and it’s a really bad message. There hasn’t been a simple message to say this is not the case, get out into the playground with some chalk and make a maze and do some computing, to teach them how to use a computer. No politician has stepped in to say this is not the case and they haven’t asked teachers who would tell them this isn’t the case. And that’s the problem. Where are the teachers? Where are the people that are actually teaching? - -**LV**: As you’ve just left teaching to join the Raspberry Pi Foundation, what are your thought Carrie Anne? - -**Carrie Anne**: It feels like a lot longer than two months, it feels like an eternity! - -**Clive**: Is that bad? - -**Carrie Anne**: No no, not at all! Because teachings so fast paced in that you’re seeing the results of what you’re doing in class straight away, whereas being out of the classroom for the past two months and working the Foundation, I can’t actually see the impact I’m having, but obviously people are talking to me and saying I am having an impact. It’s just very different to what I was seeing before. Clive always said there’s a massive difference between teaching and being a teacher. There are a lot of people we talk to who run Raspberry Jams, workshops, CoderDoJos and that kind of thing, and they always say ‘Oh, it’s really easy, you just do this, this and this.’ And it’s like, great, but you’ve got kids coming to you that *want* to learn this stuff. Imagine a class where you’ve got a bunch of kids who aren’t interested or engaged by this subject and actually teaching is much harder… - -**Clive**: Maybe 15 year olds on a Friday afternoon… - -**Carrie Anne**: Yes, a six-period day, end of the week… - -**Clive**: Ofsted saying, ‘Why haven’t your kids developed after 20 minutes in your lesson? Why haven’t they progressed?’. It’s very different. - -**Carrie Anne**: It’s very different, yep. - -**LV**: So you have some idea of how things should be done because of your recent experience? - -**Carrie Anne**: Yes. - -> The Raspberry Jams have done an excellent job of bringing people together from all walks of life - -**LV**: Are we, in general as a society, doing the right things? - -**Carrie Anne**: I think so. I think what’s been really nice about the Raspberry Pi community is that is gives back to the community. So there are experts, there are people who love what they do, who are reaching out to teachers and reaching out to children by running workshops and clubs and things. And it’s actually that collaboration that produces the best materials and produces the best way to move forward with the new curriculum. I mean, the work I did as a teacher producing the Sonic Pi was a team of work. That was because I worked with, yes an academic, but he was an expert. He wanted to develop a teaching environment that I could use with my students to teach tech-based programing in a fun and engaging way, that engaged both genders and engaged both low ability students and high ability students. It’s a tech-based programming language, which is important at Key Stage 3 where you need to not just be able to teach Scratch, you need to teach a tech-based language that’s nice bridge between Starch and something like Python, which we can teach later on. So, yeah, I think we are moving in the right direction. It would be nicer if the powers that be… - -**Clive**: It would be nice to see that as a microcosm of how these things actually happen. So as an academic has a brilliant idea and they’re very good at what they do, and then they come to a teacher and say ‘How can we make this useful in the classroom?’, ‘How can we get assessment in there?’, which schools needs frankly, ‘How do we make it robust?’, ‘How can we test it?’. And isn’t that a weird idea, to actually ask the people that teach how we should do that? It hasn’t happened really. But, yes, as Carrie says, we’re going in the right direction, certainly. The community and third parties are doing more to push it along. - -**LV**: From someone outside a little bit, it kind of looks like this community has sort of spontaneously developed around the Raspberry Pi. Has this always been there or has it just become more obvious now? - -**Carrie Anne**: I think it’s always been there. I was a teacher so when Raspberry Pi first came out I got one. It got it and then I was like, this is brilliant! Someone’s developed something for education. A Linux box that we can use in the classroom. It’s cheap, it’s brilliant! - -**Clive**: And mess about with. - -**Carrie Anne**: Yeah, it’s going to be great! And then I was like, right, so where are the resources to go with it? Ah, there aren’t any. Then I was like, so where can I go and find some? The first obvious place was Raspberry Jam. There are people running events where they’re doing stuff. So I thought I’ll go along and speak to some people, and see what’s available. And it was through that that I met people to work with, and they’d formed that themselves, the enthusiasts from throughout the community around the Raspberry Pi. - -**Clive**: It’s been a focus, hasn’t it? There’s been a lot of people sort of hanging around, saying ‘Look, I like tinkering, I like messing, I like coding, I like making’, and this thing appeared which was cheap and cheerful and fantastic to play around with, and I think it was a focus. It was waiting to happen really. - -![Carrie Ann Philbin, The Raspberry Pi Foundation’s Education Pioneer](http://www.linuxvoice.com/wp-content/uploads/carrie-ann-1.jpg) -Carrie Ann Philbin, The Raspberry Pi Foundation’s Education Pioneer - -**LV**: Was there anything equivalent to Raspberry Jams before the Raspberry Pi came along for people and teachers to come together? - -**Carrie Anne**: Well teachers tend to generally get together through things like TeachMeets and through Twitter, and those kinds of chat tools. There are ways that you can get together, but that’s more talking about teaching practice. Like the different ways you can use a sentence. It’s very teachery, it wasn’t specific to teaching computing. - -**Clive**: I think hardware-wise, Raspberry Pi was in the right place and the right time. - -**Ben**: The Jams done a really good job of bringing people together. The people, like myself, who were attending user groups that are interested in tech and really passionate about it, have got a chance to share that interest with the wider community. There were families coming in, teachers coming in, and they were just sharing what they were doing. And the skills they already had, and I was already programming in Python and things like that just on the desktop, and the Pi came along and it opened up this way of plugging into the real world and all the other things the Pi brings with it. Just being about to use those skills and pass them on, I got myself involved in Education through that. - -**LV**: So you weren’t a teacher before then? - -**Ben**: No, I was a software developer. - -**Carrie Anne**: This is what’s great about the education team at Raspberry Pi. It’s 50% ex-teachers and 50% software developers. We need people like Ben and Dave (Honess). - -**Ben**: Yes, some people have ideas for things and think this could be an engaging exercise, but they may not know exactly how to deliver it, or how it’s going to work. They might not know how exactly a teacher is supposed to produce something to use that, but they have an end goal and working with someone else can help achieve that. - -**Clive**: Yeah, you’re right, the real key is the mix. So you’re getting teachers and engineers and developers and families. Before, they might have been on a Linux user group, they might have been a teacher group, and you’re just bringing a bunch of different people together and that just (to use a horrible word!) synergizes stuff. -(Everyone LOL) - -**Clive**: Yes, I did it! I said synergizes! I’m buying a copy of the magazine now. - -**Carrie Anne**: There’s something that comes about from getting all those different types of people together is that it breeds this wonderful learning environment that you cannot reproduce. Like, you were running a Picamera workshop this morning. So that was run by people who run Jams who are from industry. And what was really nice is that there were teachers and there were people who had come for the Jamboree from industry that were helping the teachers do stuff. And there was this environment that was like, it’s ok to not know something, it’s ok to ask a question, it’s ok to get it wrong and make mistakes. And that’s really powerful because sometimes teachers are afraid perhaps of saying they don’t know. - -**Ben**: So at this workshop, we gave people an intro to building a real application around the camera. So it’s not just ‘Oh, there’s a camera and you can take pictures’. It was ‘Ok, let’s plug in a button, and attach that to the Pi and let’s make that be the button for the camera’. And just a simple intro like that opens up a world of possibilities. Sometimes a lot of these things like the Jam, just gives you a lot of inspiration. Or if you see something in a magazine or online, or on Twitter, and you think somebody’s done that with the Pi, I’d really like to do that project in my garden or I’d like to do that myself and twist it and use some of the libraries they’ve used or used some of the codebase they’ve used and take it in their own direction. - -**Clive**: Like it’s not a button, it’s a sensor for when your parents walk into your bedroom, it then tweets it as they walk in. - -**Ben**: And everyone’s got a different way of thinking. If you’re in classroom of 30 kids and you show them how to make a button do this, each of them is thinking ‘Oh I can make a such and such’. They’ll all have a different idea. And some of them will just go straight home and make one. And some of them would need a lot more guidance. - -> Every teacher needs more time off their timetable to develop their skills - -**LV**: Are there some kids that just don’t get it at all? - -**Ben**: I think there’s something for everyone, but they might not find it straight away. If you delivered a term’s worth of content for a class, with a good scope of different projects, I’d be surprised if there was one kid that wasn’t interested in any of it or didn’t find any of it engaging. - -**Clive**: It’s almost an antidote for kids not getting it. With teaching music, you’ll have people that are level 5 or 6 while others can’t read music. Because computing is creative and engaging, we don’t all have to become master coders. With Scratch, it’s a visual language and you’ll find that quite often you’ll get what are classed as low ability kids that just rip into that and do fantastic things because it’s the first time they’ve been allowed to get ideas out of their heads and make something with it. And before, if they’ve had problems with writing and numeracy, they haven’t been able to do that. There are case studies with young boys that aren’t very good at reading and writing but they start telling stories when you give them an environment where they can actually do these things. So it’s brilliant tool to actually fight the opposite. It’s not that they don’t get it. There’s something for everybody. - -![Linux Voice’s Andrew Gregory asks Clive Beale a tough question](http://www.linuxvoice.com/wp-content/uploads/pi-clive-1.jpg) -Linux Voice’s Andrew Gregory asks Clive Beale a tough question - -**LV**: Pre-Raspberry Pi, in the dark ages of about 5 years ago, before the ICT revolution, what would those children be doing? Would they have responded to ICT at all? - -**Carrie Anne**: In a classroom, you have a network of computers that are all on lockdown. You’ve got your network administrator and team of technicians, and they do a wonderful job and I certainly wouldn’t slate them – I was a technician once. But we were living in a time where you had to lock down the internet, which I disagree with, I think it should be open. And all the computers, you can’t execute any files on them, so you can’t actually teach any programming on them. So that was a problem for me. - -**LV**: Is that changing? - -**Carrie Anne**: I think it is changing, and will change with the new curriculum. For me as a teacher, what was great when the Raspberry Pi came along is that I don’t actually need those computers around the outside any more. - -**LV**: So you don’t need permission. - -**Carrie Anne**: Here’s my box full of Pis, let’s just get them out. - -**Clive**: I’ll install what you want, do what I want. - -**Carrie Anne**: Yeah, you can break it. And that’s ok, you just flash it and start again. - -**Clive**: In 1997, they put the C back in ICT and suddenly it became this thing that you had to teach. The curriculum wasn’t really that bad. A lot of people moan about it, but if you actually sat down and read it, it was quite flexible and did let you do take control and make programming and coding interesting. But because resources are so important to schools, you just ended up doing the easy things. - -**LV**: But when you said about kids using Scratch and becoming motivated to do other things, that would never have happened before the Raspberry Pi came along. - -**Clive**: Yes, it was more just following what the teacher said, ‘And now we’re going to write a letter to the cinema’ or something. That’s like giving someone a Ferrari and saying you’ve just got to drive in this room for half an hour. So you’ve given them this fantastic tool for exploration and creativity, and you’re saying we’ve got to do this. Whereas with the computing thing, especially things like Scratch, just lets them think, ‘Ok, I can do a movie, I can do a little flip frame animation, or you know what, I can actually make a game’. And then suddenly they’re doing stuff that they haven’t had the opportunity to do. - -**Carrie Anne**: Yeah, and I think that ICT curriculum was about 12 years out of date. It was created and it wasn’t updated. - -> you can break it. And that’s ok, you just flash it and start again - -**LV**: Obviously quite a lot has changed in computing education according to the media over the last couple of years in the UK. Broadly speaking, it is getting better? - -**Carrie Anne**: Yes. - -**LV**: What are the parts that pushed it to be better. - -**Carrie Anne**: I think the teachers. They’re the ones in the classroom that have to teach the curriculum. When I became a teacher, I was already working in a school and I kept putting it off becoming a teacher because the curriculum bored me. But then I realised that, when I actually got into the classroom, I was able to put my own spin on it. I think it started with the teachers. Those people saying we want a new curriculum, we want to teach this and it’s engaging the kids and they’re learning something. I think it started there and then I think industry picked up on the fact that that was happening and they wanted more industry experts. And then the government got involved and it snowballed really. - -**Clive**: Scratch was a big word-of-mouth thing wasn’t it. It was about mid-2000 when it came out, and suddenly you just found that any teacher worth their salt was using it for their ICT curriculum because it taught about control. - -**Carrie Anne**: HTML as well. HTML has been on the curriculum for years. We’ve been teaching HTML in Notepad for years. - -**LV**: What are going to be the big things pushing it forward over the next few years? - -**Carrie Anne**: I think more of the same really. It’ll be teachers, it’s always the teachers. They’re the ones that come to the Jamboree and this kind of thing, and learn from people like Ben and that sort of collaboration. That’s where it starts. The teachers see what can be done, and they start doing it, and they’ll be more of that. And there are initiatives like code clubs and the Master Teachers are great. - -**Clive**: Teachers are meeting up more when before may not have been getting together. - -**Ben**: And as well as there being a more content, I think they’ll be convergence of a lot of this stuff. So, because the Raspberry Pi doesn’t have any official resources right now, some people are going off and writing their own. I think they’ll be a convergence of people pulling their ideas together and there’ll be a more centralised system for that. And we’ll be helping the community out with that. - -**Clive**: ‘We’ll be at the forefront of that’, is that quote! - -**LV**: You haven’t mentioned government policy, or anything like that at all. Is that a negative thing or just by-the-by? - -**Clive**: I was at the Westminster forum yesterday and they had a chap from the DFE there, and I couldn’t resist it, so I got the mic and said you haven’t really taken it seriously have you? He turned round and said, we have *really* take it seriously. This idea that we can just bring in a new program of study and saying ‘Oh, aren’t we wonderful’, because Eric Schmidt’s speech and going over that, and suddenly we’re made it all better for you. But you haven’t, you just seemed to have done something that a lot of teachers are now scared of. So there’s a lot of work to do, and we’re really positive. But no, the government have not, in my personal opinion, given the money or the support or the thought behind this. If you go to Jersey, it’s such a great contrast. 6 million pounds, 100 thousand people on the island – the size of Cambridge. Compared to the 53 million in England and parts of the UK. This is in England initially, it’s not in Scotland and Wales. They’re got the infrasture, fibre to the door in every school, linking into businesses, £2 million CPD for teachers, well that’s practically what the government pay for the whole of England. So, have you taken it seriously, no. I think they’ve completing underestimated what’s involved. They thought the teachers would just pick it up and have the time and resources, which we don’t have the time for. - -**Carrie Anne**: Maggie Philbin has been leading a UK digital skills taskforce, of which I’m part the team. We’re looking at where the skill shortages are and what are digital skills. Because there’s going to a whole group of kids who are now 14 to 16 who are going to leave the education system who haven’t had new programs like these. They were on the old program, so we’re looking at who will be deskilled and what we can do about that. So hopefully that report will inform government policy. - -**Ben**: There must be a generation of people that don’t have their own website. - -**LV**: If there’s one thing you could change about government policy, what would it be? - -**Clive**: It really is to do with support for teachers. This idea that teachers would be able to, especially primary school teachers where you have to teach a range of subjects, suddenly go off, and even the guy yesterday said, well there’s loads of third party resources, but you’ve still got to go out and get them and try them out and learn and bring them all together. - -**Carrie Anne**: Time. One of the biggest recommendations that I would say is time. Every teacher needs more time off their timetable to develop their skills, especially in an area like this that they perhaps think they’re weak. Because it takes a while to set things up and start your learning. As a teacher, you get like a 30 period timetable, you’re teaching for about 22 lessons of that with about 7 free periods, but some of those you’ll be covering for another lesson and some of those I need to plan my lesson and mark. They need time. - -**Clive**: If you look at science, so if you’re a chemistry or biology teacher at secondary, there’s a scheme where you can re-skill to physics and they will give you free periods, huge bursary, and they’ll also take you off timetable one day a week to go off and go to other schools and retrain, and maybe pay for the cover. And this is the government doing this, and if you do this, this and this, you come out as an accredited physics teacher. So they took that seriously, but yet here’s a brand new subject and they’re expecting people just to pick up and run with it, and it’s completely inadequate. - -**Carrie Anne**: But it’s not just time to learn something, it’s also time to go and meet industry people. Like go to a company and be in there and work and learn from them, and see what the world is like. Because some people, they went through education, went to university and became a teacher, so they’ve never left this school environment and they’ve got no idea of what the world of work is like. - -**Ben**: I think there are some people in the current government that seem to think there should just be this package, and this is what you should deliver as your syllabus this year. Everyone is treated the same. Each teacher has their own class, and they’re all different, with different ways of engaging their interest. It needs to be tailored, so the teacher needs to take that material, and perhaps look on our site in the next year and say, well this one looks quite suitable for my class, or this one might be a good one to do. - -**Clive**: It’s so long term. The government also do not understand that this is long term. So if you’re going to start teaching at 5 about algorithms and a bit of code and Scratch, what happens further down the line. The secondary school teacher will be saying, I can’t teach them Scratch anymore, which is what we do in Year 7 at the moment. So it’s actually quite a long term thing and things will continue to change over the next several years until that pipeline becomes full. And they’ve unbelievably said here’s £2 million, do some training for September 2014. What’s 2014 got to do with it? This is five, six, seven years down the line. - --------------------------------------------------------------------------------- - -via: http://www.linuxvoice.com/education-education-education/ - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 diff --git a/sources/talk/20140609 Out in the Open--The Little-Known Open Source OS That Rules the Internet of Things.md b/sources/talk/20140609 Out in the Open--The Little-Known Open Source OS That Rules the Internet of Things.md deleted file mode 100644 index 3f70d6cd07..0000000000 --- a/sources/talk/20140609 Out in the Open--The Little-Known Open Source OS That Rules the Internet of Things.md +++ /dev/null @@ -1,49 +0,0 @@ -Translating by toknow-gh Out in the Open: The Little-Known Open Source OS That Rules the Internet of Things -================================================================================ -![](http://www.wired.com/wp-content/uploads/2014/06/Contiki-ipv6-rpl-cooja-simulation.png) -Image: Adnk/[Wikipedia][1] - -You can connect almost anything to a computer network. Light bulbs. Thermostats. Coffee makers. Even badgers. Yes, badgers. - -Badgers spend a lot of time underground, which make it difficult for biologists and zoologists to track their whereabouts and activities. GPS, for example, doesn’t work well underground or in enclosed areas. But about five years ago, University of Oxford researchers Andrew Markham and Niki Trigoni [solved that problem][2] by inventing a wireless tracking system that can work underground. Their system is clever, but they didn’t do it alone. Like many other scientists, they turned to open source to avoid having to rebuild fundamental components from scratch. One building block they used is an open source operating system called [Contiki][3]. - -“Contiki was a real enabler as it allowed us to do rapid prototyping and easily shift between different hardware platforms,” says Markham, now an associate professor at the University of Oxford. - -Contiki isn’t nearly so well-known as Windows or OS X or even Linux, but for more than a decade, it has been the go-to operating system for hackers, academics, and companies building network-connected devices like sensors, trackers, and web-based automation systems. Developers love it because it’s lightweight, it’s free, and it’s mature. It provides a foundation for developers and entrepreneurs eager to bring us all the internet-connected gadgets the internet of things promises, without having to develop the underlying operating system those gadgets will need. - -Perhaps the biggest thing Contiki has going for it is that it’s small. Really small. While Linux requires one megabyte of RAM, Contiki needs just a few kilobytes to run. Its inventor, Adam Dunkels, has managed to fit an entire operating system, including a graphical user interface, networking software, and a web browser into less than 30 kilobytes of space. That makes it much easier to run on small, low powered chips–exactly the sort of things used for connected devices–but it’s also been ported to many older systems like the Apple IIe and the Commodore 64. - -![Adam Dunkels. Photo: Sara Arnald](http://www.wired.com/wp-content/uploads/2014/06/Adam_Dunkels.jpg) -Adam Dunkels. Photo: Sara Arnald - -Contiki will soon face competition from the likes of Microsoft, which recently [announced Windows for the Internet of Things][4]. But while Microsoft’s new operating system will be free for devices less than 9 inches in size, it won’t be open source. And Contiki has an 11-year head start. - -Contiki started in 2003, but its roots stretch to Dunkels’ days as a computer science student at Mälardalen University in Sweden. In 2000, he was working on a project to use wireless sensors to track hockey players’ vital signs and display them on a screen the crowd could see. “We convinced them to have this thing up their nose so we could measure their breathing rates,” Dunkels recalls. - -To make the sensors work correctly, Dunkels had to write software would enable them to interact with a computer network. He called the resulting code [LwIP][5], for “light weight internet protocol.” Although LwIP is still used in many microcontrollers and other products today, Dunkels decided it wasn’t quite lightweight enough. In 2003, he created microIP, which evolved into Contiki. The OS was an immediate hit with researchers and hobbyists, and has in recent years attracted commercial users including [Rad-DX][6] radiation detection devices and [Zolertia][7] noise monitoring system. - -While Nest, the web connected thermostat company [Google acquired for $3.2 billion][8] in January, has come to define the Internet of Things, Dunkels notes that many companies have been using network-connected devices for years in applications including industrial and building automation. “With something like CES you see all the consumer stuff, but there are just so many different aspects of this,” Dunkel says. - -But consumer technology companies are beginning to embrace Contiki as well. The [LiFX][9] “smart light bulb” is using the operating system, for example, as is the Nest competitor [Tado][10]. - -To help support the burgeoning commercial usage of Contiki, Dunkels left his job as a professor at the Swedish Institute of Computer Science and founded [Thingsquare][11], a startup focused on providing a cloud-based back-end for Contiki devices. The idea is to make it easy for developers to connect their hardware devices with smartphones and the web. Thingsquare manages the servers, and provides all the software necessary to manage a device over the web. - --------------------------------------------------------------------------------- - -via: http://www.wired.com/2014/06/contiki/ - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://en.wikipedia.org/wiki/File:Contiki-ipv6-rpl-cooja-simulation.png -[2]:http://www.cs.ox.ac.uk/projects/WILDSENSING/ -[3]:http://www.contiki-os.org/ -[4]:http://www.wired.com/2014/04/free-windows/ -[5]:https://savannah.nongnu.org/projects/lwip/ -[6]:http://www.dtectsystems.com/rad-DX_page.html -[7]:http://zolertia.com/home -[8]:http://www.wired.com/2014/01/googles-3-billion-nest-buy-finally-make-internet-things-real-us/ -[9]:http://lifx.co/ -[10]:http://www.tado.com/de-en/ -[11]:http://www.thingsquare.com/ diff --git a/sources/talk/20140610 GitHub redesigns its Windows app to put your work front and center, adds emoji and gif support.md b/sources/talk/20140610 GitHub redesigns its Windows app to put your work front and center, adds emoji and gif support.md deleted file mode 100644 index 7ee2f2f2c1..0000000000 --- a/sources/talk/20140610 GitHub redesigns its Windows app to put your work front and center, adds emoji and gif support.md +++ /dev/null @@ -1,39 +0,0 @@ -GitHub redesigns its Windows app to put your work front and center, adds emoji and gif support -================================================================================ -![](http://cdn1.tnwcdn.com/wp-content/blogs.dir/1/files/2012/05/2012-05-21_10h05_58-657x245.jpg) - -GitHub today [released][1] version 2.0 of its Windows app, which it markets as “the easiest way to use Git and GitHub on Windows.” The new version features a more streamlined design, new GitHub local features, and some general speed improvements.

They are naturally hoping for a repeat of this jump with the 2.0 release. - -GitHub 2.0 for Windows is supposed to be simpler and cleaner, and aims to put more focus and the developer and their work.

The company has slimmed that down so developers no longer need to move back and forth between their projects. - -This is largely accomplished by adding a sidebar that reduces the need to navigate through menus and options. In short, your local repositories are always available on the left, plus you can create, clone, and publish repositories without having to navigate to a new screen. Your repositories are also grouped by where they originated from, so work projects (think GitHub Enterprise) are easy to distinguish from personal ones, and you can easily switch between them. - -The new design aside, GitHub for Windows now lets you pick an ignore file template for your project when you create a repository. It also supports including emoji and gifs in your commit messages. - -It’s worth noting that the aforementioned performance improvements should be felt around the app in general. Unfortunately, GitHub wasn’t able to share any benchmarks regarding the speed bumps. - -All in all, this is a big redesign aimed at improving the user experience.

However, "if you were trying to narrow it down to one app, it would probably still be Photoshop.

"What killer app is Linux missing?" was the question that [kicked things off][1], and the discussion has been escalating ever since. - -"The Free Software world is incredibly rich, and covers pretty much all bases," **Linux Voice's** Mike Saunders began. "We have a wealth of desktop, server, development and multimedia tools to choose from -- some of which are the best in their field. - -"But what is missing?" Sanders went on provocatively. "Is there a killer app that prevents you from running Linux 24x7 on your main machine?" - -There was a momentary lull in the conversation around the bar as patrons pondered the suggestion. Linux Girl tried to enjoy the fleeting peace, but it didn't last for more than an instant. - -### 'Depends on What You Do' ### - -![Linux Girl](http://www.linuxinsider.com/images/article_images/linuxgirl_bg_pinkswirl_150x245.jpg) - -"A long time ago Linux needed a lot of things," Google+ blogger Alessandro Ebersol offered. "These days, when every software and the kitchen sink are migrating to the cloud, everything is going to be multiplatform. - -"I would say we lacked games, but that also is being taken care of," Ebersol said. "So I don't feel that we desperately need a killer app anymore." - -The killer app "depends on what you do with your computer," consultant and [Slashdot][2] blogger Gerhard Mack opined. "If you are drafting, then the killer app is Autocad. But for other industries the killer app will be something else." - -### 'The Enterprise Space' ### - -Google+ blogger Kevin O'Brien had a similar view. - -"There isn't much left on the consumer level," O'Brien said. "I could maybe gripe about games or Nvidia drivers, and I don't really see anything that can replace Quicken. But for me the big difference maker is in the enterprise space. - -"Microsoft owns that, and there is nothing that compares to Outlook/Exchange server, Sharepoint, etc.," he asserted. "I suspect part of the reason is that there are not a lot of open source developers who really care about that stuff." - -### 'The Tide Is Changing' ### - -It's not so much a "missing app" situation as a "not-enough-critical-mass" kind of problem, Google+ blogger Gonzalo Velasco C. suggested. - -Many more people use Linux today than did five years ago, he noted; at the same time, many are tied to non-Linux-friendly applications. - -"'Everybody' uses $kype, but we have half a dozen apps for that in GNU/Linux, from the simple and very useful Pidgin (my favorite) to Ekiga and similar VoIP apps," Gonzalo Velasco C. explained. "Some users still claim they need Photo$hop and don't take the time to master and suggest improvements for GIMP, Inkscape, Bender and others." - -Games used to be missing, "but the tide is changing, mainly -- but not only -- because of Valve's brave SteamOS movement," he added. - -### 'Retail Shelf Space' ### - -"I don't think there are any 'killer' apps these days," blogger [Robert Pogson][3] agreed. "In Debian GNU/Linux, there are 40K packages. My main PC has only 3K installed and I lack nothing. I have multiple browsers, editors, compilers/interpreters, platforms, and with virtual machinery like KVM, I can play with multiple operating systems and different versions of software as needed. - -"I can treat multiple machines as if they were a single machine from anywhere on the LAN," Pogson added. "I can access resources on any node on the LAN from any machine. What more do I need?" - -That said, "several professionals have told me that video and image editors in GNU/Linux are a bit weak," he noted. "GIMP is being improved in bit-depth, so that should be covered. Lightworks will eventually be released as FLOSS, so video should be covered." - -Nevertheless, "these are tiny niches in IT," he pointed out. "Many ordinary folks go decades without using those other special applications, so I don't think this is anything holding GNU/Linux back." - -The real killer in the market, however, is lack of shelf space in retail stores, Pogson asserted. "Where that is covered, GNU/Linux thrives." - -### 'Linux Has Lost Out to OS X' ### - -Chris Travers, a [blogger][4] who works on the [LedgerSMB][5] project, had a different perspective. - -"I don't think that it is a question of killer apps," he began. "The real issue is that on the desktop, Linux has generally lost out to OS X, while it is increasingly dominating the server market along with the BSDs. People who use Linux on the desktop tend to be looking for openness." - -What Linux needs is either "the momentum of Microsoft or the smooth UI and attention to detail of OS X," Travers said. "These may come over time." - -### The Documentation Problem ### - -Linux isn't missing one killer app -- "what it's missing is polish, as always," [Hyperlogos][6] blogger Martin Espinoza opined. "No desktop environment for Linux has the polish of Windows XP, let alone Windows 7. - -"Move away from the bloat and oversimplicity of GNOME or from the widget salad of [KDE][7] to what, Xfce or LXDE, with their perfectly horrible file managers and primitive panels?" Espinoza added. "GNOME is the only DE that ever got close, and then they decided to remove all the complexity and eliminate their reason to exist." - -Windows is just "a nicer place to hang out," he asserted. - -Still, if Linux is missing anything for broader acceptance, "that is games," Espinoza said. "If you were trying to narrow it down to one app, it would probably still be Photoshop. For all the talk of how great GIMP has become, usability is still an abject nightmare, and in spite of the OSS community's self-back-patting regarding documentation, there is no documentation for GIMP which is not pathetic." - -GIMP "might be able to do most of the things Photoshop can do, but I'll probably never know," Espinoza concluded. "I suppose if I spent hours trolling fora I could find out how to use GIMP. This failing is shared by most OSS projects, including the ones that think they're really well-documented." - -### 'Ease of Use and Support' ### - -Ease of use and support are the "killer app" SoylentNews blogger hairyfeet named. - -"Oh, a freshly installed Linux distro LOOKS nice, it works great; the problem is it doesn't CONTINUE to look nice or work great," he explained. "First update and whoops! Wireless no longer can use WPA V2. Second update? Whoops, say goodbye to sound, as Pulse has puked. First 'upgrade'? Uh oh, hope you didn't need that! - -"THIS is what Windows and OS X have that Linux doesn't: the ease of use and support," hairyfeet concluded. "As long as it takes 15+ Linux releases to equal the same support cycle a single Windows release gets? Then I'm sorry, but your product is just not in the same league -- you are comparing HS baseball to the majors." - -### 'Windows 8' ### - -Last but not least, [Linux Rants][8] blogger Mike Stone had a surprising suggestion. - -"The killer app that Linux has been missing all these years is Windows 8," Stone quipped. - -"Seriously, I don't think there is a particular app that can be the 'killer app,'" he said. "Linux needs to have more mainstream application support, and that's going to mean Photoshop and Microsoft Office at the minimum. Thankfully, Microsoft has done their best to make Office less relevant, and most people don't need Photoshop." - -Linux "could be reaching critical mass, and I was only partially joking when I said Windows 8 earlier," he concluded. "The application base in Linux is starting to arrive, and the current version of Windows is remarkably unpopular. Fingers crossed we see some motion here soon." - --------------------------------------------------------------------------------- - -via: - -译者：[runningwater](https://github.com/runningwater) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.linuxvoice.com/voice-of-the-masses-what-killer-app-is-linux-missing/ -[2]:http://slashdot.org/ -[3]:http://mrpogson.com/ -[4]:http://ledgersmbdev.blogspot.com/ -[5]:http://www.ledgersmb.org/ -[6]:http://hyperlogos.org/ -[7]:http://www.kde.org/ -[8]:http://linuxrants.com/ \ No newline at end of file diff --git a/sources/talk/20140723 Linux System Administration Skills are Changing.md b/sources/talk/20140723 Linux System Administration Skills are Changing.md index 87ce32c6a1..1617d65af5 100644 --- a/sources/talk/20140723 Linux System Administration Skills are Changing.md +++ b/sources/talk/20140723 Linux System Administration Skills are Changing.md @@ -1,3 +1,5 @@ +[translated by blueabysm] + Linux System Administration Skills are Changing ================================================================================ When was the last time you compiled a kernel?

With this evolution, both good and bad revelations have been discovered. Revelations from new functionality, to broken extensions, and so forth. In this article, I'll serve as your guide through these murky waters to help you discover the best in Linux browsers. - -### **Firefox** ### - -– [Firefox][1] has long been a friendly browser for Linux users. Accessible on both 32bit and 64bit Linux installs, Firefox also offers extensive extensions to choose from. It's a fast loading, easy to navigate Web browser that has found itself in a popular place with Linux users. - -**The good**: It's easily installed from most common Linux software repositories, if not already installed on the distro by default. Thousands of extensions to choose from to make your Firefox browser more fully featured. Nearly every website on the Web (including government and banking sites) render properly. - -Also important: Firefox respects your privacy. In addition to a straight forward privacy policy, they're not in the "same business" as Google. Therefore, most users feel more comfortable allowing Firefox to see their daily browsing activities whereas other browsers, might have more profit-driven interests. Firefox is also great for web developers, thanks to its element inspection tool, built right into the browser. - -**The bad**: Not too long ago, I was finding that Firefox's frequent updates were breaking my extensions. This meant I needed to verify that my favorite extensions were compatible with new Firefox updates BEFORE I updated my browser. - -To be blunt, this caused me to rethink which browser would be my default tool to browse the Internet. In fairness, Mozilla does post a blog post with each browser update for extension developers. In these posts, developers are told what has changed and what needs to be done to keep things working smoothly. - -### **Chrome/Chromium** ### - -– Google promotes its browser named [Chrome][2], however I tend to put [Chromium][3] into the same group as Chrome since Chromium is used as its base for development. Unlike Firefox, Chrome/Chromium was late to the game for Linux. Linux users only considered it worth trying at the time due to the fact that Chrome/Chromium was perceived by many as being the fastest browser. - -**The good**: Even today, Chrome/Chromium is considered pretty fast. Even with the recent updates made to other competing browsers, Chrome/Chromium hasn't lost its speed. Extensions for Chrome/Chromium are plentiful and even better, updates to the browser have no affect on said extensions. This means that, unlike Firefox, I haven't dealt with extension incompatibilities. Like Firefox, Chrome/Chromium also has an element inspection tool, built right into the browser. After trying syncing options with other browsers, only Chrome/Chromium has proven itself to be truly idiot-proof. Without question, Chrome/Chromium syncing is the best in the browser space, from my perspective. - -**The bad**: Chrome/Chromium doesn't always render pages correctly. Be it rare, some sites like Ebay don't always render correctly. Case in point, if I create a new Ebay submission, I find there are buttons missing in some cases. I've also found that sometimes Chrome/Chromium can lockup completely if an open tab is rendering heavy script. Sites like Google Plus and Facebook are the most common offenders. - -### **Qupzilla** ### - -– When it comes to lightweight browsers, I've found [Qupzilla][4] to be among the most awesome. Based on Webkit, it provides decent rendering support while maintaining a very small resource footprint. - -**The good**: Qupzilla is ideal for lightweight desktop environments where you need a modern browser capable of rendering pages correctly and generally providing a solid web browser experience. It's extremely lightweight and will run on older PCs without missing a beat. Access Keys and [GreaseMonkey][5] extensions are installed (but disabled) by default. - -Like Firefox and Chrome/Chromium, Qupzilla provides access to an element inspection tool as well. And finally, having [Adblock][6] installed by default makes this a clear lightweight winner for me. - -**The bad**: HTML5 video doesn't seem to work reliably. Also, in order to watch Flash videos, you must visit the preferences and uncheck Click to Flash in the Extensions, Webkit plugins area. This is a poorly thought out decision to essentially disable Flash out of the box, while HTML5 video remains completely broken. - -### **Midori** ### - -– I like to call [Midori][7] the lightweight Chrome alternative. Like Google's browser(s), Midori offers a minimalist experience with its "hamburger menu," which is nice as it takes up less browser space. Not only do you get a solid browsing experience without the usual browser politics found elsewhere, Midori is also quite fast. - -**The good**: Midori is fast, lightweight and feels familiar out of the box. I'm also happy to report that it renders pages correctly and works great with sites like YouTube. The best part, in my opinion, is the built-in functionality for creating browser profiles and actual launchable links for Web apps. For example, you can easily create a web app on your desktop for Gmail or Facebook. You can also setup user specific browser profiles as well, without creating new Linux user accounts. - -**The bad**: Despite mentioning user extensions for this browser, the selection available is less than impressive. Also, the browser layout takes a bit of getting used to. A trash can for previously visited websites – seriously? - -### **Opera** ### - -– [Opera][8] has long been one of the misunderstood browsers out there. Very early on, Opera provided Linux support despite being dismissed by the overall Linux community. In addition to being a compatible, fast web browser that has been nothing but good to Linux users, it's also a full of configurable options. - -**The good**: It's fast and it's full of user controllable settings. You can import and export everything from RSS feeds to email, and skin Opera with easy access to breathtaking themes. Plus, Opera offers an extensive library of extensions to choose from. Not to mention the ability to read RSS feeds and email, from your browser! Relive the days of the Mozilla Suite by using Opera's extended suite functionality. And perhaps best of all, Opera Turbo – super-charge your browser speed with selective compression to provide a faster experience. - -**The bad**: A nag for the Terms of Service on its first run. Also, Opera Turbo can slightly alter your browsing experience – YouTube for example, may not show a video's thumbnail. Opera also provides so many options that it can feel a bit overwhelming to the casual user. And lastly, it's a closed source browser that hasn't been well recognized for desktop use. Most folks think of Opera as a mobile browser only these days. - -### Which browser is right for you? ### - -With so many great choices, it can be a tough call to say which browser is right for you. Speaking for myself, I've found that I rely heavily on Firefox and Chromium due to specific extensions I put to work each day. For someone with a lower end system or netbook, my suggestion is to try Midori first and if that's not a fit, fallback to Qupzilla. - -So what about other web browsers for Linux? Such as the [Epiphany][9] browser or [Konqueror][10]? Browsers like these are great, but I feel strongly about the browsers I've shared above specifically. Each of the options listed above are browsers I use often and have found to be something I feel good about recommending to friends and family. - -That said, by all means, share any browsers you're passionate about in the Comments below so others can benefit from your preferred method of browsing the Web. - --------------------------------------------------------------------------------- - -via: http://www.datamation.com/open-source/best-linux-browsers-1.html - -原文作者：[Matt Hartley][a] - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[a]:http://www.datamation.com/author/Matt-Hartley-3080.html -[1]:https://www.mozilla.org/en-US/firefox/new/ -[2]:https://www.google.com/intl/en_us/chrome/browser/ -[3]:http://www.chromium.org/ -[4]:http://www.qupzilla.com/ -[5]:https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/ -[6]:https://adblockplus.org/ -[7]:http://midori-browser.org/ -[8]:http://www.opera.com/ -[9]:https://wiki.gnome.org/Apps/Web -[10]:http://www.konqueror.org/ \ No newline at end of file diff --git a/sources/talk/20140724 What are useful online tools for Linux.md b/sources/talk/20140724 What are useful online tools for Linux.md deleted file mode 100644 index 75aed3d17a..0000000000 --- a/sources/talk/20140724 What are useful online tools for Linux.md +++ /dev/null @@ -1,151 +0,0 @@ -[translating by KayGuoWhu] -What are useful online tools for Linux -================================================================================ -As you know, GNU Linux is much more than just an OS. There is literally a whole sphere on the Internet dedicated to the penguin OS. If you read this post, you are probably inclined towards reading about Linux online. Among all the pages that you can find on the subject, there are a couple of websites that every Linux adventurer should have in his bookmarks. These websites are more than just tutorials or reviews. They are real tools that you can access from anywhere and share with everyone. So today I shall propose you a non-exhaustive list of sixteen websites that should be in your bookmarks. Some of them can also be useful for Windows or Mac users: that's the extent of their reach. - -### 1. [ExplainShell.com][1] ### - -[![](https://farm4.staticflickr.com/3841/14517716647_3b6a1a564d_z.jpg)][2] - -If you are interested in Linux command line, you should use this website. If you are not interested in Linux command line, you should use it even more as it will explain in detail how a command works. This could prevent you from launching a command detrimental to your computer, and is a good way to learn with a great interface. - -### 2. [BashrcGenerator.com][3] ### - -[![](https://farm4.staticflickr.com/3900/14703872782_033e5acdb8_z.jpg)][4] - -If you want to begin with Linux command line, or if you want to quickly get a customized shell prompt but not sure how, this website will generate for you PS1 prompt code to place your .bashrc file in your home directory. You can drag and drop the elements that you would like to see in your prompt, like your username and the current time, and the website will write the code for you. It's easy and very readable. Definitely a must for the lazy. - -### 3. [Vim-adventures.com][5] ### - -[![](https://farm4.staticflickr.com/3838/14681149696_0c533fd6de_z.jpg)][6] - -I only recently discovered this website, but it already sucked in many hours of my life. In short: a RPG game with Vim commands. Move your character in the isometric levels with the 'h,j,k,l' keys, gain new commands/abilities, collect keys, and learn how to use Vim proficiently very quickly. - -### 4. [Try Github][7] ### - -[![](https://farm4.staticflickr.com/3874/14517499739_0452848d68_z.jpg)][8] - -The pitch is simple: learn Git in 15 minutes. This website simulates a console, and walks you though the steps of collaborative editing. The interface is very stylish and the intention is worthy. The only downside is for the Git allergic. But it is definitely a good skill to have, and a good place to learn it. - -### 5. [Shortcutfoo.com][9] ### - -[![](https://farm4.staticflickr.com/3906/14517499799_f142ea37cb_z.jpg)][10] - -Another shortcut database, shortcutfoo is a bit more standard in its way to present its content to the user, but definitely more straight-forward than funny mini-games. The shortcuts of several programs are available and grouped by categories. As it might not be super complete for software like Vim, which is completely reliant on shortcuts, it is perfect for giving a quick tip or a general overview. - -### 6. [GitHub Free Programming Books][11] ### - -[![](https://farm4.staticflickr.com/3867/14517499989_408a28d8be_z.jpg)][12] - -As you might guess from the URL, this is a collection of free online books about programming, written collaboratively using Git. The content is awesome and the authors deserve to be praised for such work. It might not be the easiest read at first, but it is one of the most instructive for sure. We can only hope that the movement will keep growing. - -### 7. [Collabedit.com][13] ### - -[![](https://farm3.staticflickr.com/2940/14681150086_2d169d67f9_z.jpg)][14] - -If you ever plan on giving a phone interview, you should check out collabedit beforehand. It allows you to create a document, select the programming language that you want to write in, and then share that document via the URL. The people opening the link will be able to freely interact in real time with the text, allowing you to judge their programming skills or just exchange snippets. It even comes with the proper syntax highlighting and a chat widget. In other words, it is the instant-Google Document of programmers. - -### 8. [Cpp.sh][15] ### - -[![](https://farm4.staticflickr.com/3840/14700981001_af3ac40b65_z.jpg)][16] - -This is one of those websites that extend beyond just Linux, but it is so useful that it deserves its place here. In short, an online development environment for C++. Just write your code in your navigator and run it. As a bonus, you get an auto-indentation feature, Ctrl+Z, and the possibility to share the URL with your buddy. This is just one of those crazy things that you can do from a simple browser. - -### 9. [Copy.sh][17] ### - -[![](https://farm4.staticflickr.com/3883/14517479870_da521931eb_z.jpg)][18] - -In continuation with crazy things that you can do from your browser, copy.sh lets you run a virtual machine online. Just that. It gained fame relatively recently, but the idea is just insane. From the navigator you can select among the defaults virtual images to run, or upload your own iso file. The code for that feat has been shared on [GitHub][19]. Just amazing. - -### 10. [Commandlinefu.com][20] ### - -[![](https://farm4.staticflickr.com/3887/14517495938_ca3b831ca9_z.jpg)][21] - -We all keep a big snippet of command-line "gems" on our computer. commandlinefu's goal is to release those snippets to the world. As a collaborative database, it resembles the Wikipedia of the command line. Everyone is free to register and post their favorite command on the website for everyone else to see. You will then be able to access that knowledge from everywhere and share it with everyone. If you are interested in mastering the shell, commandlinefu also proposes great features like random commands and a news feed to learn something new every day. - -### 11. [Alias.sh][22] ### - -[![](https://farm4.staticflickr.com/3868/14701762124_a7b3547aca_z.jpg)][23] - -Another collaborative database, alias.sh (I love the URL) is a bit like commandlinefu but for shell aliases. You can share and discover useful aliases which will make your CLI experience so much better. I personally like the alias to get the dimensions of a picture. - - function dim(){ sips $1 -g pixelWidth -g pixelHeight } - -All the seconds you save with alias.sh probably accumulate with time, and turn to years by the end of your life. - -### 12. [Distrowatch.com][24] ### - -[![](https://farm3.staticflickr.com/2910/14681149996_50a45bff78_z.jpg)][25] - -Who does not know Distrowatch? Besides giving a precise ranking of Linux distributions based on their website popularity, Distrowatch is also a very useful database. Whether you are looking for a new distribution to try, or just curious, it presents an exhaustive account of every Linux you can find, with information like which default desktop environment it uses, or package system, or its default applications. And all the versions, and with easily accessible download links. In a word, the Linux database. - -### 13. [Linuxmanpages.com][26] ### - -[![](https://farm4.staticflickr.com/3911/14704165765_8e30cb3d3f_z.jpg)][27] - -Everything is in the URL: access the manual pages for popular commands from anywhere. Not really sure if this would actually be useful for Linux users as you can access that from your actual terminal, but the intent is remarkable. - -### 14. [AwesomeCow.com][28] ### - -[![](https://farm6.staticflickr.com/5558/14704165965_02b10ee293_z.jpg)][29] - -This is maybe a bit less hardcore Linux, but definitely useful to some. Awesomecow is a search engine for finding alternatives to Windows software on Linux. It can be helpful for anyone migrating to the penguin, or nostalgic of a Windows program. I see this as a strength, showing that Linux can compete with the professional spheres when it comes sot software quality. Or at least try to. - -### 15. [PenguSpy.com][30] ### - -[![](https://farm4.staticflickr.com/3904/14517495728_f6877e8e3b_z.jpg)][31] - -Before Steam started to show up on Linux, gaming was probably one of the penguin's weakness. But the website penguspy made the effort of fighting that weakness by collecting all Linux compatible games in a database with a sexy interface. Games can be sorted by categories, release dates, ratings, etc. I really hope that websites like this are not going to disappear because of Steam as it remains one of my favorites of this list. - -### 16. [Linux Cross Reference by Free Electrons][32] ### - -[![](https://farm4.staticflickr.com/3913/14712049464_6b666e2cfa_z.jpg)][33] - -Finally, for all the experts and the curious, lxr is the anagram from Linux Cross Reference, and allows us to interactively view the Linux Kernel code online. The navigation is made easy via identifiers, and you can compare the different versions of the files with a standard diff markup. The interface is sober and straight-forward, and this is just a website that perfectly illustrates the concept of open source. - -To conclude, there are a lot more websites which deserve to be listed, and this might be a topic for a part two to this post. But this is a good start. It serves as an appetizer to what can be found online as tools for Linux users. If you have any other pages that you would like to share, following this thematic, do so in the comments. And maybe contribute to a sequel to this list. - --------------------------------------------------------------------------------- - -via: http://xmodulo.com/2014/07/useful-online-tools-linux.html - -原文作者：[Adrien Brochard][a](I am a Linux aficionado from France.

Often the answer is to fix the violation, but sometimes Linus Torvalds decides that the POSIX behavior is broken, in which case they keep the Linux behavior, but they might build an additional POSIX compatibility layer, even if that layer is slower and less efficient. - -This time, *Michael Kerrisk* reported a POSIX violation that affected file operations. Apparently, reading and writing to files during multithreaded operations could hit race conditions and overwrite each other's changes. - -There was some discussion over whether this was really a violation of POSIX, but ultimately, who cares? Data clobbering is bad. After Michael posted some code to reproduce the problem, the conversation focused on what to do to fix it. But Michael did make an argument that "Linux isn't consistent with UNIX since early times. (E.g., page 191 of the 1992 edition of Stevens APUE discusses the sharing of the file offset between the parent and child after fork(). Although Stevens didn't explicitly spell out the atomicity guarantee, the discussion there would be a bit nonsensical without the presumption of that guarantee.)" - -Al Viro joined Linus in trying to come up with a fix. Linus tried introducing a simple mutex to lock files so that write operations couldn't clobber each other, and Al offered his own refinements that improved on Linus' patch. - -At one point, Linus explained the history of the bug itself. Apparently, once upon a time the file pointer, which told the system where to write into the file, had been locked in a semaphore so only one process could do anything to it at a time. But, they took it out of the semaphore in order to accommodate device files and other non-regular files that ran into race conditions when users were barred from writing to them whenever they pleased. - -That was what introduced the bug. At the time, it slipped through undetected, because that actual reading and writing to regular files was still handled atomically by the kernel. It was only the file pointer itself that could get out of sync. And, because high-speed threaded file operations are a pretty rare need, it took a long time for anyone to run into the problem and report it. - -An interesting little detail is that, while Linus and Al were hunting for a fix, Al at one point complained that the approach Linus was taking wouldn't support certain architectures, including *ARM* and *PowerPC*. Linus' response was, "I doubt it's worth caring about. [...] If the ARM/PPC people end up caring, they could add the struct-return support to gcc." - -It's always interesting to see how corner cases crop up and get dealt with. In some cases, part of the fix has to happen in the kernel, part in GCC and part elsewhere. In this particular instance, Al felt the whole thing could be done in the kernel, and he was inspired to write his own version of the patch, which Linus accepted. - -*Andi Kleen* wanted to add low-level CPU event support to *perf*. The problem was that there could be tons of low-level events, and it varied widely from CPU to CPU. Even storing the possible events in memory for all CPUs would significantly increase the kernel's running size. So, hard-coding this information into the kernel would be problematic. - -He pointed out that the *OProfile* tool relied on publicly available lists of these events, though he said the OProfile developers didn't always keep their lists up to date with the latest available versions. - -To solve these issues, Andi submitted a patch that allowed perf to identify which event-list was needed for the particular CPU on the given system, and automatically download the latest version of that list from its home location. Then perf could interpret the list and analyze the events, without overburdening the kernel. - -There was various feedback to Andi's code, mostly to do with which directory should house the event-lists, and what the filenames should be called. The behavior of the code itself seemed to get a good reception. One detail that may turn out to be more controversial than the others was Andi's decision to download the lists to a subdirectory of the user's own home directory. Andi said that otherwise users might be encouraged to download the event-lists as the root user, which would be bad security practice. - -Sasha Levin recently posted a script to translate the *hexadecimal offsets *from stack dumps into meaningful line numbers that pointed into the kernel's source files. So something like "ffffffff811f0ec8" might be translated into "fs/proc/generic.c:445". - -However, it turned out that Linus Torvalds was planning to remove the hex offsets from the stack dumps for exactly the reason that they were unreadable. So Sasha's code was about to go out of date. - -They went back and forth a bit on it. At first Sasha decided to rely on data stored in the System.map file to compensate, but Linus pointed out that some people, including him, didn't keep their System.map file around. Linus recommended using /usr/bin/nm to extract the symbols from the compiled kernel files. - -So, it seems as though Sasha's script may actually provide meaningful file and line numbers for debugging stack dumps, assuming the stack dumps provide enough information to do the calculations. - --------------------------------------------------------------------------------- - -via: http://www.linuxjournal.com/content/diff-u-whats-new-kernel-development-0 - -原文作者：[Zack Brown][a] - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[a]:http://www.linuxjournal.com/user/801501 \ No newline at end of file diff --git a/sources/talk/20140729 Don't Fear The Command Line.md b/sources/talk/20140729 Don't Fear The Command Line.md new file mode 100644 index 0000000000..8a9c4acb68 --- /dev/null +++ b/sources/talk/20140729 Don't Fear The Command Line.md @@ -0,0 +1,138 @@ +Love-xuan 翻译中 +Don't Fear The Command Line +================================================================================ +![](http://a4.files.readwrite.com/image/upload/c_fill,h_900,q_70,w_1600/MTE5NTU2MzIyNTM0NTg5OTYz.jpg) + +> Embrace your computer's most useful tool. + +You've probably seen it in movies, even if you haven't ever called it up on your own computer: a blank screen with a simple text prompt and a cursor, just waiting for you to enter the appropriate arcane commands to do your bidding. + +This is the command line. It's a text-based interface that predates the far more familiar windows, icons and tiles of today's major computer operating systems, from Windows to Mac OS X to Linux. + +The command line is an extremely powerful tool for accessing basic functions of your computer. For most people, it's also a confusing, complicated and seemingly irrelevant distraction. It doesn't have to be. + +### Computers Under Your Command ### + +Typing text instructions and hitting Return to get a computer to do something sounds like a major step back compared to the swipe-and-tap touch-sensitive interfaces of mobile devices. Even a toddler can use an iPad, right? Yet the command line can save you time and aggravation, if you know when to use it. + +If you're serious about learning to code—or just understanding computer technology—you absolutely need to get to know your command line. + +Diving into the command line will teach you a lot about how your computer works and organizes information. You might find that some tasks you perform every day with a mouse are actually faster when you type a command or two instead. + +Most important, you’ll be better prepared to learn [languages like Python][1] and [programs like Git][2] that require some command-line setup. By getting familiar with the command line, you’ll break down barriers that may have kept you from learning to program in the past. + +So here's a quick, basic guide to getting around on the command line. It's focused on Mac OS X's Unix-based environment, simply because that's what I'm familiar with. Linux users probably know the command line well already, although newcomers might also find these tips useful. If you're running a Chromebook, Google has some helpful instructions for getting to its [version of the command line][3], which is similar to Mac and Linux systems. Windows users, unfortunately, are stuck with a command language derived from MS-DOS that just barely overlaps with Unix, so this guide isn't going to be much use to you; you might check out [this dosprompt.info tutorial][4]. + +### How To Find Your Way Around ### + +The very first thing you’ll need to do is figure out how to access the command line, which is typically done through a program called a "shell." On any Mac running OS X, you'll need to start the Terminal application. You can do this through the Finder (it's in the Utilities folder under Applications), or just click the magnifying glass in the upper right hand corner of your screen and type “terminal,” then select it from the drop-down. + +![](http://a4.files.readwrite.com/image/upload/c_fit,w_630/MTE4MDAzNDE2ODYxMjc5NzU4.png) + +You’re in, but all you see is a blank box with a space to type prompts. This is the command line! Let’s get to know this window a little bit better. + +Type pwd, which stands for Print Working Directory. In computer parlance, “printing” something has nothing to do with paper. It really just means spitting it out on the screen. The command should result in the computer returning the directory you are currently working in. + +![](http://a4.files.readwrite.com/image/upload/c_fit,w_630/MTIyMzk5Mjg5MDMzMjYyNjA0.png) + +And indeed, /Users/laurenorsini is my home directory. Advanced tip: You can use the tilde symbol (~) as a shortcut for your home directory—it means the same thing as /Users/yourusername. So you can reference your Downloads subdirectory, for instance, as ~/Downloads. (If you look closely at the command prompt above, you'll see a tilde there. That indicates that I'm in my home directory.) + +We don’t want to muddy up our main directory with all our command-line experimenting, so let’s make a new directory with the mkdir command. This is the same as creating a new folder on your desktop operating system. Let's call it "experiments": + +![](http://a4.files.readwrite.com/image/upload/c_fit,w_630/MTE5NDg0MDYxMTMwODUxODU1.png) + +Now we have a new directory. Using the graphic interface, we can visually verify that we actually created a new one. Sure enough, if I open the Finder and go into my home directory—here marked with a little house icon—I now see a folder named “experiments.” I made that on the command line! (The reverse works, too: You can create a folder on your desktop, and see it in the command line. They're just two different ways of looking at the same system.) + +![](http://a5.files.readwrite.com/image/upload/c_fit,w_630/MTE5NTU2MzIyNTM0MzI3ODE5.png) + +Now I need to change directories and enter the ~/experiments directory with the **cd** (change directory) command. + +![](http://a5.files.readwrite.com/image/upload/c_fit,w_630/MTE5NDg0MDYxMTMxMTEzOTk5.png) + +I have my command prompt on the default setting, so it automatically shows where my working directory is. But if yours looks different, here's how to make sure “experiments” is truly your working directory: type **pwd** again. It should tell you that your working directory is “experiments.” + +### Getting Filed Away ### + +I create and edit files on the command line every day that I code. It's faster than using the graphical user interface because I can test out my programs on the command line as soon as I finish editing them. And if I also happen to be pushing things to [GitHub][5] at the same time, well, it's even more convenient. + +Now you have a new directory (also called a repository or folder) on your computer to mess around with. Let's start by creating a new file that contains only the words, "Hello World." There are a lot of ways to do this; here I'm using the echo command. + +Now you have a new directory (also called a repository or folder) on your computer to mess around with. Let's start by creating a new file that contains only the words, "Hello World." There are a [lot of ways][6] to do this; here I'm using the **echo** command. + +![](http://a2.files.readwrite.com/image/upload/c_fit,w_630/MTE5NDg0MDYxMjQxMjgwMDE1.png) + +Oh no! I spelled "newfile" incorrectly. That happens. Let's fix it in two steps. First, I'll create a new file with the correct spelling... + +![](http://a3.files.readwrite.com/image/upload/c_fit,w_630/MTIxNDI3Mjk0MjA5ODAzNzg5.png) + +And then, I'll use the **mv** (move) command to replace my old, misspelled file with my new file. This always takes the form "**mv oldfile newfile**." + +![](http://a1.files.readwrite.com/image/upload/c_fit,w_630/MTIxNDI3Mjk0MjA5NzM4MjUz.png) + +A note about **mv**: like many commands, it's a deceptively powerful one. When we're "moving" newfil.txt into newfile.txt, what we're actually doing is completely overwriting the first file and replacing it with the second. So the text I wrote into newfil.txt is gone forever, replaced by what I wrote into newfile.txt. + +To prove that I only have one file in my directory, I can use **ls** , the list command, to get a list of all the files in this directory. + +![](http://a1.files.readwrite.com/image/upload/c_fit,w_630/MTIxNDI3Mjk0MTA3NTAyMDkz.png) + +See? Just the one. And if I look inside the folder using my computer's graphical user interface, I can see the file there, too. + +![](http://a3.files.readwrite.com/image/upload/c_fit,w_630/MTIyMzk5Mjg5MDM4OTY0MjM2.png) + +But it's just a blank text file. Let's put something inside it using a text editor. On the command line, I tend to use the nano editor since it's simple and it works on just about every type of computer. + +This should immediately bring up a new editing screen right inside your command line window. The basic commands are all laid out for you. + +![](http://a3.files.readwrite.com/image/upload/c_fit,w_630/MTIyMzk5Mjg5MDM5NjE5NTk2.png) + +Write what you want, and then exit with CTRL + X. If it asks you to save and you'd like to, type "Y." + +![](http://a4.files.readwrite.com/image/upload/c_fit,w_630/MTIxNDI3Mjk0MTA4MDkxOTE3.png) + +As you've probably guessed by now, it's possible to also see these changes by using the operating system and navigating to newfile.txt with your mouse. Here you can open and edit the file you've created in any text editor of your choice. + +If you want to delete the file forever, do that with the **rm** (remove) command: + +![](http://a2.files.readwrite.com/image/upload/c_fit,w_630/MTE5NTU2MzIyNTQxMzQwMTcx.png) + +Keep in mind that the **rm** command is very powerful! A [common trick][7] on hacker forums is to convince a command-line newbie to type **rm -rf** / so she ends up deleting her whole computer. The "/" means the very top-level directory of your computer—and everything underneath it. NEVER type that command! + +### Further Reading ### + +This is just the beginning of the endless possibilities of the command line. You can use this tool to control every aspect of your computer, which is what makes it as dangerous as it is powerful. Make sure to always read up on new command-line prompts before you use them, and never blindly input a prompt that a stranger suggests to you online. + +I've outlined the commands I use every day so I can code, but there are a lot more reasons to master the command line than that.

Although the words mean almost the same thing, you don’t need a word processor for these tasks; you need a text editor. + +In this group test we’ll be looking at five humble text editors that are more than capable of heavy-lifting texting duties. They can highlight syntax and auto-indent code just as effortlessly as they can spellcheck documents. You can use them to record macros and manage code snippets just as easily as you can copy/paste plain text. + +Some simple text editors even exceed their design goals thanks to plugins that infuse them with capabilities to rival text-centric apps from other genres. They can take on the duties of a source code editor and even an Integrated Development Environment. + +Two of most popular and powerful plain text editors are Emacs and Vim. However, we didn’t include them in this group test for a couple of reasons. Firstly, if you are using either, congratulations: you don’t need to switch.

Geddit keeps most of its features hidden. + +### The crucial criteria ### + +All the tools, except Gedit and jEdit, were installed on Fedora and Ubuntu via their recommended installation method. The former already shipped with the default Gnome desktop and the latter stubbornly refused to install on Fedora. Since these are relatively simple apps, they have no esoteric dependencies, the only exception being jEdit, which requires Oracle Java. + +Thanks to the continued efforts of both Gnome and KDE, all editors look great and function properly irrespective of the desktop environment they are running on. That not only rules it out as an evaluation criterion, it also means that you are no longer bound by the tools that ship with your favourite desktop environment. + +In addition to their geekier functionality, we also tested all our candidates for general-purpose text editing. However, they are not designed to mimic all the functionality of a modern-day word processor and weren’t evaluated as such. + +![Kate can double up as a versatile can capable integrated development environment (IDE).](http://www.linuxvoice.com/wp-content/uploads/2014/08/kate-web.png) + +Kate can double up as a versatile can capable integrated development environment (IDE). + +### Programming language support ### + +UltraEdit does syntax highlighting, can fold code and has project management capabilities. There’s also a function list, which is supposed to list all the functions in the source file, but it didn’t work for any of our test code files. UltraEdit also supports HTML5, and has a HTML toolbar with which you can add commonly-used HTML tags. + +Even Gnome’s default text editor, Gedit, has several code-oriented features such as bracket matching, automatic indentation, and will also highlight syntax for various programming languages including C, C++, Java, HTML, XML, Python, Perl, and many others. + +If you’re looking for more programming assistance, look at Sublime and Kate. Sublime supports several programming languages and (as well as the popular ones) is able to highlight syntax for C#, D, Dylan, Erlang, Groovy, Haskell, Lisp, Lua, MATLAB, OCaml, R, and even SQL. If that isn’t enough for you, you can download add-ons to support even more languages. + +Furthermore, its syntax highlighting ability offers several customisable options. The app will also match braces, to ensure they are all properly rounded off, and the auto-complete function in Sublime works with variables created by the user. + +Just like Komodo IDE, sublime also displays a scrollable preview of the full source code, which is really handy for navigating long code files and lets you jump between different parts of the file. + +One of the best features of Sublime is its ability to run code for certain languages like C++, Python, Ruby, etc from within the editor itself, assuming of course you have the compiler and other build system tools installed on your computer. This helps save time and eliminates the need to switch out to the command line. + +You can also enable the build system in Kate with plugins. Furthermore, you can add a simple front-end to the GDB debugger. Kate will work with Git, Subversion and Mercurial version control systems, and also provides some functionality for project management. + +It does all this in addition to highlighting syntax for over 180 languages, along with other assistance like bracket matching, auto-completion and auto-indentation. It also supports code folding and can even collapse functions within a program. + +The only disappointment is jEdit, which bills itself as a programmer’s text editor, but it struggled with other basic functions such as code folding and wouldn’t even suggest or complete functions. + +**Verdict:** + +- Gedit:3/5 +- Kate:5/5 +- Sublime:5/5 +- UltraEdit3/5 +- jEdit:1/5 + +![If you don’t like Sublime’s Charcoal appearance, you can choose one of the other 22 themes included with ti.](http://www.linuxvoice.com/wp-content/uploads/2014/08/sublime-web.png) + +If you don’t like Sublime’s Charcoal appearance, you can choose one of the other 22 themes included with ti. + +### Keyboard control ### + +Users of an advanced text editor expect to control and operate it exclusively via the keyboard. Furthermore, some apps even allow their users to further customise the key bindings for the shortcuts. + +You can easily work with Gedit using its extensive keyboard shortcut keys. There are keys for working with and editing files as well as invoke tools for common tasks such as spellchecking a document. You can access a list of default shortcut keys from within the app, but there’s no graphical way to customise them. Similarly, to customise the keybindings in Sublime, you need to make modifications in its XML keymap files. Sublime has been criticised for its lack of a graphical interface to define keyboard shortcuts, but long-term users have defended the current file-based mechanism, which gives them more control. + +UltraEdit is proud of its “everything is customisable” motto, which it extend to keyboard shortcuts. You can define custom hotkeys for navigating the menus and also define your own multi-key key-mappings for accessing its plethora of functions. + +In addition to its fully customisable keyboard shortcuts, jEdit also has pre-defined keymaps for Emacs. Kate is equally impressive in this respect. It has an easily accessible window to customise the key bindings. You can change the default keys, as well as define alternate ones. Furthermore, Kate also has a Vi mode which will let users operate Kate using Vi keys. + +**Verdict:** + +- Gedit:2/5 +- Kate:5/5 +- Sublime:3/5 +- UltraEdit:4/5 +- jEdit:5/5 + +### Snippets and macros ### + +Macros help you cut down the time spent on editing and organising data by automating repetitive steps, while Snippets of code extend a similar functionality to programmers by creating reusable chunks of source code. Both have the ability to save you time. + +The vanilla Gedit installation doesn’t have either of these functionalities, but you can enable them via separate plugins. While the Snippets plugin ships with Gedit, you’ll have to manually download and install the macro plugin (it’s called gedit-macropy and is hosted on GitHub) before you can enable it from within Gedit. + +Kate takes the same plugins route to enable the snippets feature. Once added, the plugin also adds a repository of snippets for PHP, Bash and Java. You can display the list of snippets in the sidebar for easier access. Right-click on a snippet to edit its contents as well as its shortcut key combination. However, very surprisingly, it doesn’t support macros – despite repeated hails from users since 2002! + +jEdit too has a plugin for enabling snippets. But it can record macros from user actions and you can also write them in the BeanShell scripting language (BeanShell supports scripted objects as simple method closures like those in Perl and JavaScript). jEdit also has a plugin that will download several macros from jEdit’s website. + +Sublime ships with inbuilt ability to create both snippets and macros, and ships with several snippets of frequently used functions for most popular programming languages. + +Snippets in UltraEdit are called Smart Templates and just like with Sublime you can insert them based upon the kind of source file you’re editing. To complement the Macro recording function, UltraEdit also has an integrated javascript-based scripting language to automate tasks. You can also download user-submitted macros and scripts from the editor’s website. + +**Verdict:** + +- Gedit:3/5 +- Kate:1/5 +- Sublime:5/5 +- UltraEdit:5/5 +- jEdit:5/5 + +![UltraEdit’s UI is highly configurable — you can customise the layout of the toolbars and menus just as easily as you can change many other aspects.](http://www.linuxvoice.com/wp-content/uploads/2014/08/ultraedit-web.png) + +UltraEdit’s UI is highly configurable — you can customise the layout of the toolbars and menus just as easily as you can change many other aspects. + +### Ease of use ### + +Unlike a bare-bones text editor, the text editors in this feature are brimming with features to accommodate a wide range of users — from document writers to programmers. Instead of stripping features from the apps, their developers are looking for avenues to add more functionality. + +Although at first glance most apps in this group test have a very similar layout, upon closer inspection, you’ll notice several usability differences. We have a weak spot for apps that expose their functionality and features by making judicious use of the user interface, instead of just overwhelming the user. + +### Gedit: 4/5 ### + +Gedit wears a very vanilla look. It has an easy interface with minimal menus and buttons. This is a two-edged sword though, as some users might fail to realise its true potential. + +The app can open multiple files in tabs that can be rearranged and moved between windows. Users can optionally enable panels on the side and bottom for displaying a file browser and the output of a tool enabled by a plugin. The app will detect when an open file is modified by another application and offers to reload that file. + +The UI has been given a major overhaul in the latest version of the app yet to make its way into Gnome. However it isn’t yet stable, and while it maintains all features, several plugins that interact with the menu will need to be updated. + +### Kate: 5/5 ### + +Although a major part of its user interface resembles Gedit, Kate tucks in tabs at either side and its menus are much fuller. The app is approachable and invites users to explore other features. + +Kate can transparently open and save files over all protocols supported by KDE’s KIO including HTTP, FTP, SSH, SMB and WebDAV. You can use the app to work with multiple files at the same time. But unlike the traditional horizontal tab switching bar in most app, Kate has tabs on either side of the screen. The left sidebar will display an index of open files. Programmers who need to see different parts of the same file at the same time will also appreciate its ability to split the interface horizontally as well as vertically. + +### Sublime: 5/5 ### + +Sublime lets you view up to four files at the same time in various arrangements. There’s also a full-screen distraction free mode that just displays the file and the menu, for when you’re in the zone. + +The editor also has a minimap on the right, which is useful for navigating long files. The app ships with several snippets for popular functions in several programming languages, which makes it very usable for developers. Another neat editing feature, whether you are working with text documents or code, is the ability to swap and shuffle selections. + +### UltraEdit: 3/5 ### + +UltraEdit’s interface is loaded with several toolbars at the top and bottom of the interface. Along with the tabs to switch between documents, panes on either side and the gutter area, these leave little room for the editor window. + +Web developers working with HTML files have lots of assistance at their fingertips. You can also access remote files via FTP and SFTP. Advanced features such as recording a macro and comparing files are also easily accessible. + +Using the app’s Preferences window you can tweak various aspects of the app, including the colour scheme and other features like syntax highlighting. + +### jEdit: 3/5 ### + +In terms of usability, one of the first red-flags was jEdit’s inability to install on RPM-based distros. Navigating the editor takes some getting used to, since its menus aren’t in the same order as in other popular apps and some have names that won’t be familiar to the average desktop user. However, the app include detailed inbuilt help, which will help ease the learning curve. + +jEdit highlights the current line you are on and enables you to split windows in multiple viewing modes. You can easily install and manage plugins from within the app, and in addition to full macros, jEdit also lets you record quick temporary ones. + +![Thanks to its Java underpinnings, jEdit doesn’t really feel at home on any desktop environment](http://www.linuxvoice.com/wp-content/uploads/2014/08/jedit-web.png) + +Thanks to its Java underpinnings, jEdit doesn’t really feel at home on any desktop environment + +### Availability and support ### + +There are several similarities between Gedit and Kate. Both apps take advantage of their respective parent project, Gnome and KDE, and are bundled with several mainstream distros. Yet both projects are cross-platform and have Windows and Mac OS X ports as well as native Linux versions. + +Gedit is hosted on Gnome’s web infrastructure and has a brief user guide, information about the various plugins, and the usual channels of getting in touch including a mailing list and IRC channel. You’ll also find usage information on the websites of other Gnome-based distros such as Ubuntu. Similarly, Kate gets the benefit of KDE’s resources and hosts detailed user information as well as a mailing list and IRC channel. You can access their respective user guides offline from within the app as well. + +UltraEdit is also available for Windows and Mac OS X besides Linux, and has detailed user guides on getting started, though there’s none included within the app. To assist users, UltraEdit hosts a database of frequently asked questions, a bunch of power tips that have detailed information about several specific features, and users can engage with one another other on forum boards. Additionally, paid users can also seek support from the developers via email. + +Sublime supports the same number of platforms, however you don’t need to buy a separate licence for each platform. The developer keeps users abreast with ongoing development via a blog and also participates actively in the hosted forums. The highlight of the project’s support infrastructure is the freely available detailed tutorial and video course. Sublime is lovely. + +Because it’s written in Java, jEdit is available on several platforms. On its website you’ll find a detailed user guide and links to documentation of some plugins. However, there are no avenues for users to engage with other users or the developer. + +**Verdict:** + +- Gedit: 4/5 +- Kate: 4/5 +- Sublime: 5/5 +- UltraEdit: 3/5 +- jEdit: 2/5 + +### Add-on and plugins ### + +Different users have different requirements, and a single lightweight app can only do as much. This is where plugins come into the picture. The apps rely on these small pluggable widgets to extend their feature set and be of use to even more number of users. + +The one exception is UltraEdit. The app has no third-party plugins, but its developers do point out that third-party tools such as HtmlTidy are already installed with UltraEdit. + +Gedit ships with a number of plugins installed, and you can download more with the gedit-plugins package. The project’s website also points to several third-party plugins based on their compatibility with the Gedit versions. + +Three useful plugins for programmers are Code Comment, Terminal Plugin, which adds a terminal in the bottom panel, and the Session Saver. The Session Saver is really useful when you’re working on a project with multiple files. You can open all the files in tabs, save your session and when you restore it with a single click it’ll open all the files in the same tab order as you saved them. + +Similarly, you can extend Kate by adding plugins using its built-in plugin manager. In addition to the impressive projects plugins, some others that will be of use to developers include an embedded terminal, ability to compile and debug code and execute SQL queries on databases. + +Plugins for Sublime are written in Python, and the text editor includes a tool called Package Control, which is a little bit like apt-get in that it enables the user to find, install, upgrade and remove plugin packages. With plugins, you can bring the Git version control to Sublime, as well as the JSLint tool to improve JavaScript. The Sublime Linter plugin is a must have for coders and will point out any errors in your code. + +jEdit boasts the most impressive plugin infrastructure. The app has over 200 plugins, which can be browsed in the dedicated site of their own. The website lists plugins under various categories such as File Management, Version Control, Text, etc. You’ll find lots of plugins housed under each category. + +Some of the best plugins are the Android plugin, which provides utilities to work on Android projects; the TomcatSwitch plugin, using which you can create and control an external Jakarta Tomcat server process; and the Vimulator plugin, for Vi-like capabilities. You can install these plugins using jEdit’s using its plugin manager. + +**Verdict** + +- Gedit: 3/5 +- Kate: 4/5 +- Sublime: 4/5 +- UltraEdit: 1/5 +- jEdit: 5/5 + +### Plain ol’ text editing ### + +Despite all their powerful extra-curricular activities that might even displace full-blown apps across several genres, there will be times when you just need to use these text editing behemoths to read, write, or edit plain and simple text. While you can use all of them to enter text, we are evaluating them for access to common text-editing conveniences. + +Gedit which is Gnome’s default text editor, supports an undo and redo mechanism as well as search and replace. It can spellcheck documents in multiple languages and can also access and edit remote files using Gnome GVFS libraries. + +You can spellcheck documents with Kate as well, which also lets you perform a Google search on any highlighted text. It’s also got a line modification system which visually alerts users of lines which have modified and unsaved changes in a file. In addition, it enables users to set bookmarks within a file to ease navigation of lengthy documents. + +Sublime has a wide selection of editing commands, such as indenting text and formatting paragraphs. Its auto-save feature helps prevent users from losing their work. Advanced users will appreciate the regex-based recursive find and replace feature, as well as the ability to select multiple non-contiguous spans of text and act on them collectively. + +UltraEdit also enables the use of regular expressions for its search and replace feature and can edit remote files via FTP. One unique feature of jEdit is its support for an unlimited number of clipboard which it calls registers. You can copy snippets of text to these registers which are available across editing sessions. + +**Verdict:** + +- Gedit: 4/5 +- Kate: 5/5 +- Sublime: 5/5 +- UltraEdit: 4/5 +- jEdit: 4/5 + +### Our verdict ### + +All the editors in this feature are good enough to replace your existing text editor for editing text files and tweaking configuration files. In fact, chances are they’ll even double up as your IDE. These apps are chock full of bells and whistles, and their developers aren’t thinking of stripping features, but adding more and more and more. + +At the tail end of this test we have jEdit. Not only does it insist on using the proprietary Oracle Java Runtime Environment, it failed to install on our Fedora machine, and the developer doesn’t actively engage with its users. + +UltraEdit does little better. This commercial proprietary tool focuses on web developers, and doesn’t offer anything to non-developer power users that makes it worth recommending over free software alternatives. + +On the third podium position we have Gedit. There’s nothing inherently wrong with Gnome’s default editor, but despite all its positive aspects, it’s simply outclassed by Sublime and Kate. Out of the box, Kate is a more versatile editor than Gedit, and outscores Gnome’s default editor even after taking their respective plugin systems into consideration. + +Both Sublime and Kate are equally good. They performed equally well in most of our tests. Whatever ground it lost to Sublime for not supporting macros, it gained for its keyboard friendliness and its ease of use in defining custom keybindings. + +Kate’s success can be drawn from the fact that it offers the maximum number of features with minimal learning curve. Just fire it up and use it as a simple text editor, or easily edit configuration file with syntax highlighting, or even use it to collaborate and work on a complex programming project thanks to its project management capabilities. + +We aren’t pitching Kate to replace a full-blown integrated development environment such as [insert your favourite specialised tool here]. But it’s an ideal all-rounder and a perfect stepping stone to a specialised tool. + +Kate is designed for moments when you need something that’s quick to respond, doesn’t overwhelm you with its interface and is just as useful as something that might otherwise be overkill. + +### 1st Kate ### + +- Licence LGPL/GPL Version 3.11 +- www.kate-editor.org +- The ultimate mild-mannered text editor with super powers. +- Kate is one of the best apps to come out of the KDE project. + +### 2nd Sublime Text ### + +- Licence Proprietary Version 2.0.2 +- www.sublimetext.com +- A professionally done text editor that’s worth every penny – easy to use, full of features and it looks great. + +### 3rd Gedit ### + +- Licence GPL Version 3.10 +- http://projects.gnome.org/gedit +- Gets it done from Gnome. It’s a wonderful text editor and does an admirable job, but the competition here is too great. + +### 4th UltraEdit ### + +- Licence Proprietary Version 4.1.0.4 +- www.ultraedit.com +- Focuses on bundling conveniences for web developers without offering anything special for general users. + +### 5th jEdit ### + +- Licence GPL Version 5.1.0 +- www.jedit.org +- A lack of support, lack of working on Fedora and a lack of looking nice relegate jEdit to the bottom slot. + +### You may also wish to try… ### + +The default text editor that ships with your distro will also be able to assist you with some advanced tasks. There’s KDE’s KWrite and Raspbian’s Nano, for instance. KWrite inherits some of Kate’s features thanks to KDE’s katepart component, and Nano has sprung back into limelight thanks to its availability for Raspberry Pi. + +If you wish to follow the steps of Linux gurus, you could always try the revered text editors Emacs and Vim. First time users who want to get a taste for the power of Vim might want to consider gVim, which exposes Vim’s power via a graphical interface. + +Besides jEdit and Kate, there are other editors that mimic the usability of veteran advanced editors like Emacs and Vim, such as the JED editor and Joe’s Own Editor, both of which have an emulation mode for Emacs. On the other hand, if you are looking for lightweight code editors check out Bluefish and Geany. They exist to fill the niche between text editors and full-fledged integrated development platforms. + +-------------------------------------------------------------------------------- + +via: http://www.linuxvoice.com/text-editors/ + +作者：[Ben Everard][a] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[a]:http://www.linuxvoice.com/author/ben_everard/ \ No newline at end of file diff --git a/sources/talk/20140804 Microsoft's Raspberry Pi Will Cost $300.md b/sources/talk/20140804 Microsoft's Raspberry Pi Will Cost $300.md new file mode 100644 index 0000000000..3192f039a4 --- /dev/null +++ b/sources/talk/20140804 Microsoft's Raspberry Pi Will Cost $300.md @@ -0,0 +1,28 @@ +Microsoft’s Raspberry Pi Will Cost $300 +================================================================================ +![](http://itsfoss.itsfoss.netdna-cdn.com/wp-content/uploads/2014/08/Sharks_Cove_Microsoft.jpg) + +I presume that you have heard of [Raspberry Pi][1].

In this article I'll also detail a few of my favourite classic games that are now available to play in Linux.** + +It's not all nostalgia, though. Some of the classic games you might think of are genuinely classic, amazing games no matter their age. Others, you might need to imagine you're back in, say, 1995 and look at the game from that point of view to appreciate how good it must have seemed at that time. Whatever the case though, there's no shortage of these old games out there to enjoy and thankfully it's recently gotten even easier with [GOG.com][1] recently announcing Linux support. + +A lot of these old classic games actually run in [DOSBox][2], so a seasoned Linux gamer who has experience with such games may bring up the point that you could play a lot of these games provided by services such as GOG.com for years already, well before that recent announcement. Which is correct, I've done the same thing myself, but it does involve a bit of fiddling with files, so at the very least we now have a "turn-key" solution even with the DOSBox powered games - you download them, you launch them, they should just work. If you just want to purchase a game and play it right away, that's no bad thing. + +Then there's the non-DOS games. A lot of old Windows 95/98 games do often work fine in WINE, but not always, or perhaps need workarounds to be manually applied or even a special version of WINE itself. Some old games just won't work at all no matter what you try, even on modern versions of Windows itself! So again, having an alternative available that is designed to work out-of-the-box (and DRM-free, no less) is a nice thing. + +GOG.com initially provided 50 Linux compatible games on their penguin-friendly launch, but that number is and will keep growing. In coming months they say they hope to reach 100 games, and who knows how many thereafter, but it should grow to be a fairly considerable library. + +Here are a few of my favourites so far, that are available right now: + +### Rise Of The Triads Dark War (1994) ### + +![](http://thelinuxrain.com/content/01-articles/70-nostalgic-gaming-on-linux-with-good-old-games/rott.png) + +If you crave some 90's style shoot-em-up action where you get to blow the hell out of, well, everything and everyone, Rise Of The Triads (ROTT) is one of the best choices and a favourite to many. + +If you know these kinds of shooters, you probably know what to expect. There is a storyline, but really it's about blowing everything up and/or riddling enemies full of bullet holes. As a member of an elite group of operatives you are sent to a remote island to stop a mad cult leader, where typically everything goes pear-shaped and you have to kill everything and successfully navigate levels to save the day and get out alive in the process. + +True to the arcade-style shooter of this vintage, weapons are all about being big, high-tech and fun. You might be in an elite operations group, but you ain't stuck with peashooters and standard rifles - no there's duel pistols all the way to heat seeking missiles and the Flamewall cannon and many more. It's all about genuine fun and doesn't take itself too seriously. + +*Verdict: A blast (literally)* + +### Realms Of The Haunting (1996) ### + +![](http://thelinuxrain.com/content/01-articles/70-nostalgic-gaming-on-linux-with-good-old-games/roth.png) + +This one is actually fairly new to me and isn't a game I remember from years back. Which is my loss really, as I can imagine this game must have seemed pretty incredible all the way back in 1996. + +Realms Of The Haunting is something of a first-person shooter/point-and-click adventure combination. The controls at first seem a bit strange because of this (keyboard to control movement and attack etc. Mouse to move the context indicator/cursor around the screen and interact with objects) but you soon get used to it. The storyline, although I have not experienced all of it yet myself, is apparently very good and certainly my impressions of it have been good. This is also one of those classic games that uses good old FMV (Full Motion Video) for cutscenes. + +![](http://thelinuxrain.com/content/01-articles/70-nostalgic-gaming-on-linux-with-good-old-games/roth1.png) + +Basically you play as a young man who receives a suitably vague letter from your recently deceased father about a strange deserted mansion and it's curious happenings inside. Naturally, said young man decides to visit the mansion and discovers his father's spirit being held captive by the forces of evil and then sets out to try free him. That sounds like a pretty standard storyline at first but the difference lays in the execution and how it progresses. + +From the moment the main character picks up a lantern and gazes around the dark, creepy surroundings of the mansion, it actually reminds me a bit of Amnesia: The Dark Descent. Sure, the gameplay and amount of actual combat means the comparison somewhat ends after that, but ROTH does also have it's fair share of exploration and puzzles. Despite a very dated looking graphics engine (it is based on the DOOM engine after all!) it strikes me how much attention to detail the game creators managed to pack into the environment, which further adds to the atmosphere and immersion despite the constant pixel party happening on screen. + +All in all, Realms Of The Haunting is a creepy but very intriguing old game that is very much worth checking out. And if you love games that feature old-school FMV, there is heaps on offer here too. + +*Verdict: Ahead of it's time?* + +### Sid Meier's Colonization (1994) ### + +![](http://thelinuxrain.com/content/01-articles/70-nostalgic-gaming-on-linux-with-good-old-games/colonization.jpg) + +Think Civilization, but with a colonial twist. Instead of building a nation from a mound of dirt in the middle of nowhere, Colonization tasks you with controlling either the forces of England, France, Spain or The Netherlands as you set about managing expansion across the Atlantic for your nation of choice. The aim of the game, as far as winning goes, is to achieve independence from your mother country and defeat the angry Royal Expeditionary Force that comes your way. + +If big chunky pixels, even in text, is something that hurts your eyes you may want to avoid this one but the simple old graphics belie the actual gameplay and depth available here. If you have experience with the more modern Sid Meier turn-based strategy games like the Civilization series, you may be surprised just how much familiar elements and gameplay there is in this old game. + +It may appear ancient and a little clunky, but like most of the classic Sid Meier games, you can sink hours upon hours into this game. Which considering it's price nowadays, no more than a piece of cake and a coffee, is fantastic value that is hard to beat. Do try it. + +*Verdict: Superb turn-based strategy, all the way from 1994* + +### Sword Of The Samurai (1989) ### + +![](http://thelinuxrain.com/content/01-articles/70-nostalgic-gaming-on-linux-with-good-old-games/sots.png) + +This one is a little more obscure and may surprise. For me, and this will sound a little cliché given the Japanese theme and setting, but there is something rather Zen about Sword Of The Samurai. A product in the year 1989, the graphics are obviously simple and have a very limited colour palette. Yet, I think even today the graphics work for this particular game and add to its charm and, again, the Zen. + +Describing SOTS is difficult though. It's sort of... a strategy, war, dating, stealth, melee, dueling, diplomacy, choose-your-own adventure Samurai sim. + +Seriously. + +Somehow this old game, which weighs in less than 20 megabytes, fits in an incredible amount of different gameplay (and surprisingly smart artificial intelligence) and approaches you can take to achieve your goal. The core goal is get a very important thing called Honor. In the world of feudal Japan, Honor is a big, big thing and you must get more Honor any way you can in order to achieve the goal of unifying Japan under your rule, as Shogun. + +While you can of course be the "good guy" and do everything you think is right to get Honor, the game is inherently deep and clever enough to allow you to achieve Honor even with, shall we say, more underhanded tactics. + +It's difficult to truly describe all the ways you can play this game but my advice is to simply do so - play it, let it wash over you and soak in the Japanese culture and atmosphere that the game exudes in a really classy way, without being over-the-top. And yes, the game can also be educational! You can't beat that. + +*Verdict: An under-appreciated masterpiece* + +### Get your game on ### + +So there we have it, there's some of my favourites that I've been (re)playing recently, on my Fedora 20 system no less. Some of these games may be older than Linux (the kernel) itself, but thanks to the likes of GOG.com and especially emulators like DOSBox, you can still enjoy the classic titles you remember from years gone by. + +What are some of your favourite classic games?

While the Android 0.5 milestone builds were "early looks," by now 1.0 was only two months away. Thus, Android 0.9 was labeled "beta." On the other side of the aisle, Apple already released its second version of the iPhone—the iPhone 3G—a month prior. The second-gen iPhone brought a second-gen iPhone OS. Apple also launched the App Store and was already taking app submissions. Google had a lot of catching up to do. - -Google threw out a lot of the UI introduced in Milestone 5. All the artwork was redone again in full-color, and the white square icon backgrounds were tossed. While still an emulator build, 0.9 offered something that looked familiar when compared to a released version of Android. Android 0.9 had a working desktop-style home screen, a proper app drawer, multiple home screens, a lot more apps, and fully functional (first-party only) widgets. - -Milestone 5 seemingly had no plan for someone installing more than 21 apps, but Android 0.9 had a vertically scrolling app drawer accessible via a gray tab at the bottom of the screen. Back then, the app drawer was actually a drawer. Besides acting as a button, the gray tab could be pulled up the screen and would follow your finger, just like how the notification panel can be pulled down. There were additional apps like Alarm Clock, Calculator, Music, Pictures, Messaging, and Camera. - -This was the first build with a fully customizable home screen. Long pressing on an app or widget allowed you to drag it around. You could drag an app out of the app drawer and make a home screen shortcut or long press on an existing home screen shortcut to move it. - -0.9 is a reminder that Google was not the design powerhouse it is today. In fact, some of the design work for Android was farmed out to other companies at the time. You can see one sign of this in the clock widget, which contains the text “MALMO," the home town of design firm [The Astonishing Tribe][2]. - -![The “Add to Home" dialog in Android 0.9.](http://cdn.arstechnica.net/wp-content/uploads/2013/12/widgets.png) -The “Add to Home" dialog in Android 0.9. -Photo by Ron Amadeo - -There were only three widgets: Clock, Picture frame, and Search. The Search widget didn't even have a proper icon in the list—it used the Picture icon. Perhaps the most interesting item here was a "Purchased pictures" option in the wallpaper choices—a leftover from the days when purchasing ringtones on a dumbphone was a common occurrence. Google was either planning on selling wallpapers, or it was already adding a carrier at some point. The company never went through with the plan. - -![A collection of widgets, an open folder, renaming a folder, and the copy/paste menu.](http://cdn.arstechnica.net/wp-content/uploads/2013/12/fcp.png) -A collection of widgets, an open folder, renaming a folder, and the copy/paste menu. -Photo by Ron Amadeo - -The left screen, above, shows the widgets for Google Search and pictures. Search didn't do anything other than give you a box to type in—there was no auto complete or additional UI. Typing in the box and hitting "Go" would launch the browser. The bottom row of icons revealed a few options for "shortcuts" from the long press menu, which created icons that opened an app to a certain screen. Individual contacts, browser bookmarks, and music playlists were all shortcuts that could all be added to the home screen in 0.9. - -"Folders" was an option under the shortcuts heading despite not being a shortcut to anything. Once a blank folder was created, icons could be dragged into it and rearranged. Unlike today, there was no indication of what was in a folder; it was always a plain, white, empty-looking icon. - -0.9 was also the first Android version to have OS-level copy/paste support. Long pressing on any text box would bring up a dialog allowing you to save or recall text from the clipboard. iOS didn't support copy/paste until almost two years later, so for a while, this was one of Android's big differentiators—and the source of many Internet arguments. - -![From left to right: Android 0.9’s new menu, recent apps, power options, and lock screen.](http://cdn.arstechnica.net/wp-content/uploads/2013/12/stuff.jpg) -From left to right: Android 0.9’s new menu, recent apps, power options, and lock screen. -Photo by Ron Amadeo - -Android 0.9 was really starting to show its maturity. The home screen had a full set of menu items, including a settings option (although it didn't work yet) and a search button (because Google likes it when you search). The menu design was already in the final form that would last until Android 2.3 swapped it to black. - -Long pressing on the hardware home button brought up a 3x2 grid of recent apps, a design that would stick around until the release of Android 3.0. Recent Apps blurred the exposed background, but that was strangely applied here and not on other popups like the "Add to home" dialog or the home screen folder view. The power menu was at least included in the blurry background club, and it was redesigned with icons and more commonly accepted names for functions. The power menu icons lacked padding, though, appearing cramped and awkward. - -Android 0.9 featured a lock screen, albeit a very basic one. The black and gray lock screen had no on-screen method of unlocking—you needed to hit the hardware menu button. - ----------- - -![Ron Amadeo](http://cdn.arstechnica.net/wp-content//uploads/authors/ron-amadeo-sq.jpg) - -[Ron Amadeo][a] / Ron is the Reviews Editor at Ars Technica, where he specializes in Android OS and Google products.

As examples, I noticed: - -- _genres to list all genres -- _play random to play a random track -- _pause to pause the current track -- _playlist new to make a new playlist -- _loop to loop current track -- _cinema to watch and ASCII version of Star Wars which completely blew my mind. - -And it even supports auto-completion via the tabulation key for genres. - -To conclude, Soundcloud2000 is a neat program that does exactly what it is supposed to.

Proxy Server is now a corporate culture and is the need of the hour. Proxy server now a days is implemented from small schools, cafeteria to large MNCs. Squid (also known as proxy) is such an application which acts as proxy server and one of the most widely used tool of its kind. + +This Interview article aims at strengthening your base from Interview point on the ground of proxy server and squid. + +![Squid Interview Questions](http://www.tecmint.com/wp-content/uploads/2014/07/Squid-Interview-Questions.png) +Squid Interview Questions + +### 1. What do you mean by Proxy Server? What is the use of Proxy Server in Computer Networks? ### + +> **Answer** : A Proxy Server refers to physical machine or Application which acts intermediate between client and resource provider or server. A client seeks for file, page or data from the the proxy server and proxy server manages to get the requested demand of client fulfilled by handling all the complexities in between. + +Proxy servers are the backbone of WWW (World Wide Web). Most of the proxies of today are web proxies. A proxy server handles the complexity in between the Communication of client and Server. Moreover it provides anonymity on the web which simply means your identity and digital footprints are safe. Proxies can be configured to allow which sites client can see and which sites are blocked. + +### 2. What is Squid? ### + +> **Answer** : Squid is an Application software released under GNU/GPL which acts as a proxy server as well as web cache Daemon. Squid primarily supports Protocol like HTTP and FTP however other protocols like HTTPS, SSL,TLS, etc are well supported. The feature web cache Daemon makes web surfing faster by caching web and DNS for frequently visited websites. Squid is known to support all major platforms including Linux, UNIX, Microsoft Windows and Mac. + +### 3. What is the default port of squid and how to change its operating port? ### + +> **Answer** : The default port on which squid runs is 3128. We can change the operating port of squid from default to any custom unused port by editing its configuration file which is located at /etc/squid/squid.conf as suggested below. + +Open ‘/etc/squid/squid.conf’ file and with your choice of editor. + + # nano /etc/squid/squid.conf + +Now change this port to any other unused port. Save the editor and exit. + + http_port 3128 + +Restart the squid service as shown below. + + # service squid restart + +### 4. You works for a company the management of which ask you to block certain domains through squid proxy server. What are you going to do? ### + +> **Answer** : Blocking domain is a module which is implemented well in the configuration file. We just need to perform a little manual configuration as suggested below. + +a. Create a file say ‘blacklist’ under directory ‘/etc/squid’. + + # touch /etc/squid/blacklist + +b. Open the file ‘/etc/squid/blacklist’ with nano editor. + + # nano /etc/squid/blacklist + +c. Add all the domains to the file blacklist with one domain per line. + + .facebook.com + .twitter.com + .gmail.com + .yahoo.com + ... + +d. Save the file and exit. Now open the Squid configuration file from location ‘/etc/squid/squid.conf’. + + # nano /etc/squid/squid.conf + +e. Add the lines below to the Squid configuration file. + + acl BLACKLIST dstdom_regex -i “/etc/squid/blacklist” + http_access deny blacklist + +f. Save the configuration file and exit. Restart Squid service to make the changes effective. + + # service squid restart + +### 5. What is Media Range Limitation and partial download in Squid? ### + +> **Answer** : Media Range Limitation is a special feature of squid in which just the required data is requested from the server and not the whole file. This feature is very well implemented in various videos streaming websites like Youtube and Metacafe where a user can click on the middle of progress bar hence whole video need not be fetched except for the requested part. + +The squid’s feature of partial download is implemented well within windows update where downloads are requested in the form of small packets which can be paused. Because of this feature a update downloading windows machine can be restarted without any fear of data loss. Squid makes the Media Range Limitation and Partial Download possible only after storing a copy of whole data in it. Moreover the partial download gets deleted and not cached when user points to another page until Squid is specially configured somehow. + +### 6. What is reverse proxy in squid? ### + +> **Answer** : Reverse proxy is a feature of Squid which is used to accelerate the web surfing for end user. Say the Real server ‘RS’ contains the resource and ‘PS’ is the proxy Server. The client seek some data which is available at RS. It will rely on RS for the specified data for the first time and the copy of that specified data gets stored on PS for configurable amount of time. For every request for that data from now PS becomes the real source. This results in Less traffic, Lesser CPU usages, Lesser web resource utilization and hence lesser load to actual server RS. But RS has no statistics for the total traffic since PS acted as actual server and no Client reached RS. ‘X-Forwarded-For HTTP’ can be used to log the client IP although on RS. + +Technically it is feasible to use single squid server to act both as normal proxy server and reverse proxy server at the same point of time. + +### 7. Since Squid can be used as web-cache Daemon, is it possible to Clear its Cache? How? ### + +> **Answer** : No Doubt! Squid acts as web-cache Daemon which is used to accelerate web surfing still it is possible to clear its cache and that too very easily. + +a. First stop Squid proxy server and delete cache from the location ‘/var/lib/squid/cache’ directory. + + # service squid stop + # rm -rf /var/lib/squid/cache/*< + +b. Create Swap directories. + + # squid -z + +### 8. A client approaches you, who is working. They want the web access time be restricted for their children. How will you achieve this scenario? ### + +Say the web access allow time be 4′o clock to 7′o clock in the evening for three hours, sharply form Monday to Friday. + +a. To restrict web access between 4 to 7 from Monday to Friday, open the Squid configuration file. + + # nano /etc/squid/squid.conf + +b. Add the following lines and save the file and exit. + + acl ALLOW_TIME time M T W H F 16:00-19:00 + shttp_access allow ALLOW_TIME + +c. Restart the Squid Service. + + # service squid restart + +### 9. Squid stores data in which file format? ### + +> **Answer** : Data stored by Squid is in ufs format. Ufs is the old well-known Squid storage format. + +### 10. Where do cache gets stored by squid? ### + +> **Answer** : A squid stores cache in special folder at the location ‘/var/spool/squid’. + +That’s all for now.

And unlike formal programming languages, a shell script doesn't require you to **declare a type** for your variables + +In this article we will discuss variables, its types and how to set & use variables in shell scripting. + +### System Defined Variables : ### + +These are the variables which are created and maintained by **Operating System(Linux) itself**. Generally these variables are defined in **CAPITAL LETTERS**. We can see these variables by using the command "**$ set**". Some of the system defined variables are given below : + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
System Defined Variables Meaning
BASH=/bin/bash Shell Name
BASH_VERSION=4.1.2(1) Bash Version
COLUMNS=80 No. of columns for our screen
HOME=/home/linuxtechi Home Directory of the User
LINES=25 No. of columns for our screen
LOGNAME=LinuxTechi LinuxTechi Our logging name
OSTYPE=Linux OS type
PATH=/usr/bin:/sbin:/bin:/usr/sbin Path Settings
PS1=[\u@\h \W]\$ Prompt Settings
PWD=/home/linuxtechi Current Working Directory
SHELL=/bin/bash Shell Name
USERNAME=linuxtechi User name who is currently login to system
+ +To Print the value of above variables, use **echo command** as shown below : + + # echo $HOME + # echo $USERNAME + +We can tap into these environment variables from within your scripts by using the environment variable's name preceded by a dollar sign. This is demonstrated in the following script: + + $ cat myscript + + #!/bin/bash + # display user information from the system. + echo “User info for userid: $USER” + echo UID: $UID + echo HOME: $HOME + +Notice that the **environment variables** in the echo commands are replaced by their current values when the script is run. Also notice that we were able to place the **$USER** system variable within the double quotation marks in the first string, and the shell script was still able to figure out what we meant. There is a **drawback** to using this method, however. Look at what happens in this example: + + $ echo “The cost of the item is $15” + The cost of the item is 5 + +That is obviously not what was intended. Whenever the script sees a dollar sign within quotes, it assumes you're referencing a variable. In this example the script attempted to display the **variable $1** (which was not defined), and then the number 5. To display an actual dollar sign, you **must precede** it with a **backslash character**: + + $ echo “The cost of the item is \$15” + The cost of the item is $15 + +That's better. The backslash allowed the shell script to interpret the **dollar sign** as an actual dollar sign, and not a variable. + +### User Defined Variables: ### + +These variables are defined by **users**. A shell script allows us to set and use our **own variables** within the script. Setting variables allows you to **temporarily store data** and use it throughout the script, making the shell script more like a real computer program. + +**User variables** can be any text string of up to **20 letters, digits**, or **an underscore character**. User variables are case sensitive, so the variable Var1 is different from the variable var1. This little rule often gets novice script programmers in trouble. + +Values are assigned to user variables using an **equal sign**. No spaces can appear between the variable, the equal sign, and the value (another trouble spot for novices). Here are a few examples of assigning values to user variables: + + var1=10 + var2=-57 + var3=testing + var4=“still more testing” + +The shell script **automatically determines the data type** used for the variable value. Variables defined within the shell script maintain their values throughout the life of the shell script but are deleted when the shell script completes. + +Just like system variables, user variables can be referenced using the dollar sign: + + $ cat test3 + #!/bin/bash + # testing variables + days=10 + guest="Katie" + echo "$guest checked in $days days ago" + days=5 + guest="Jessica" + echo "$guest checked in $days days ago" + $ + +Running the script produces the following output: + + $ chmod u+x test3 + $ ./test3 + Katie checked in 10 days ago + Jessica checked in 5 days ago + $ + +Each time the variable is **referenced**, it produces the value currently assigned to it. It's important to remember that when referencing a variable value you use the **dollar sign**, but when referencing the variable to assign a value to it, you do not use the dollar sign. Here's an example of what I mean: + + $ cat test4 + #!/bin/bash + # assigning a variable value to another variable + value1=10 + value2=$value1 + echo The resulting value is $value2 + $ + +When you use the **value** of the **value1** variable in the assignment statement, you must still use the dollar sign. This code produces the following output: + + $ chmod u+x test4 + $ ./test4 + The resulting value is 10 + $ + +If you forget the dollar sign, and make the value2 assignment line look like: + +value2=value1 +you get the following output: + + $ ./test4 + The resulting value is value1 + $ + +Without the dollar sign the **shell interprets** the variable name as a **normal text string**, which is most likely not what you wanted. + +### Use of Backtick symbol (`) in shell variables : ### + +The **backtick allows** you to assign the output of a shell command to a variable. While this doesn't seem like much, it is a major building block in **script programming**.You must surround the entire command line command with backtick characters: + + **testing=`date`** + +The shell runs the command within the **backticks** and assigns the output to the variable testing. Here's an example of creating a variable using the output from a normal shell command: + + $ cat test5 + #!/bin/bash + # using the backtick character + testing=`date` + echo "The date and time are: " $testing + $ + +The variable testing receives the output from the date command, and it is used in the echo statement to display it. Running the shell script produces the following output: + + $ chmod u+x test5 + $ ./test5 + The date and time are: Mon Jan 31 20:23:25 EDT 2011 + +**Note** : In bash you can also use the alternative $(…) syntax in place of backtick (`),which has the advantage of being re-entrant. + +Example : + + $ echo " Today’s date & time is :" $(date) + Today’s date & time is : Sun Jul 27 16:26:56 IST 2014 + +-------------------------------------------------------------------------------- + +via: http://www.linuxtechi.com/variables-in-shell-scripting/ + +作者：[Pradeep Kumar][a] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[a]:http://www.linuxtechi.com/author/pradeep/ \ No newline at end of file diff --git a/sources/tech/20140801 What are better alternatives to basic command line utilities.md b/sources/tech/20140801 What are better alternatives to basic command line utilities.md new file mode 100644 index 0000000000..e36d0200a9 --- /dev/null +++ b/sources/tech/20140801 What are better alternatives to basic command line utilities.md @@ -0,0 +1,106 @@ +What are better alternatives to basic command line utilities +================================================================================ +The command line can be scary especially at the beginning. You might even experience some command-line-induced nightmare. Over time, however, we all realize that the command line is actually not that scary, but extremely useful. In fact, the lack of shell is what gives me an ulcer every time I have to use Windows. The reason for the change in perception is that the command line tools are actually smart. The basic utilities, what you are given to work with on any Linux terminal, are very powerful. But very powerful is never enough. If you want to make your command line experience even more pleasant, here are a few applications that you can download to replace the default ones, and will provide you with far more features than the originals. + +### dfc ### + +As an LVM user, I really like to keep an eye on my hard drive memory usage. I also never really understood why in Windows we have to open the file explorer to know this basic information. Hopefully on Linux, we can use the command. + + $ df -h + +![](https://farm4.staticflickr.com/3858/14768828496_c8a42620a3_z.jpg) + +which gives you the size, usage, free space, ratio, and mount point of every volume on your computer. Notice that you have to pass in the "-h" argument to get all the data in human readable format (gigabytes instead of kilobytes). But you can replace completely df with [dfc][1], which can, without any additional arguments, get you everything that df showed, and throw in a usage graph for each device, and a color code, which makes it a lot easier to read. + +![](https://farm6.staticflickr.com/5594/14791468572_a84d4b6145_z.jpg) + +As a bonus, you can sort the volumes using the argument "-q", define the units that you want to see with "-u", and even export to csv or html format with "-e" + +### dog ### + +Dog is better than cat. At least that is what this program declares. You have to give it credit for once. Everything that the cat command does, [dog][2] does it better. Beyond just outputting some text stream to the console, dog is capable of filtering that stream. You can for example find all images in a web page by using the syntax: + + $ dog --images [URL] + +![](https://farm6.staticflickr.com/5568/14811659823_ea8d22d045_z.jpg) + +Or all the links with: + + dog --links [URL] + +![](https://farm4.staticflickr.com/3902/14788690051_7472680968_z.jpg) + +Besides, dog commands can also do other smaller tasks, like convert to upper or lower case, use different encoding, display the line numbers, and deal with hexadecimal. In short, dog is a must-have to replace cat. + +### advcp ### + +One of the most basic command in Linux is the copy command: cp. It is probably as basic as cd. Yet it cruelly lacks feedback. You can enable the verbose mode to see which files are being copied in real time, but if one of the files is very big, you will be left waiting in front of your screen with no idea of what is really happening behind the scenes. An easy way to fix that is to add a progress bar: what advcp (short for advanced cp) does! Available as a [patched version][3] of the [GNU coreutils][4], advcopy provides you with the acp and amv commands, which are "advanced" versions of cp and mv. Use the syntax: + + $ acp -g [file] [copy] + +to copy a file to another location, and display a progress bar. + +![](https://farm6.staticflickr.com/5588/14605117730_fe611fc234_z.jpg) + +I also advise using an alias in your .barshrc or .zshrc + + alias cp="acp -g" + alias mv="amv -g" + +### The Silver Searcher ### + +Behind this atypical name, [the silver searcher][5] is a utility designed as a replacement for grep and [ack][6]. Intended to be faster than ack, and capable of ignoring files unlike grep, the silver searcher scrolls through your text file looking for the piece that you want. Among other features, it can spit out a colored output, follow symlink, use regular expressions, and even ignore some patterns. + +![](https://farm4.staticflickr.com/3876/14605308117_f966c77140_z.jpg) + +The developers' website provides us with some benchmark statistic on the search speed which, if they are still true, are quite impressive. And cherry on the cake: you can include the utility in Vim in order to call it with a simple shortcut. In two words, smart and fast. + +### plowshare ### + +All fans of the command line like to use wget or one of its alternatives to download things from the internet. But if you use a lot of file sharing websites, like mediafire or rapidshare, you will be glad to know that there is an equivalent to wget dedicated to those websites, which is called [plowshare][7]. Once you install it, you can download files with: + + $ plowdown [URL] + +or upload them with: + + $ plowup [website name] [file] + +given that you have an account for that file sharing website. + +Finally, it is possible to gather information, such as a list of links contained in a shared folder with: + + $ plowlist [URL] + +or the filename, size, hash, etc, with: + + $ plowprobe [URL] + +plowshare is also a good alternative to the slow and excruciating jDownloader for those of you who are familiar with these services. + +### htop ### + +If you use top command regularly, chances are you will love [htop][8] command. Both top and htop offer a real-time view of running processes, but htop boasts of a number of user-friendly features lacking in top command. For example, with htop, you can scroll process list vertically or horizontally to see full command lines of every process, and can do basic process management (e.g., kill, (re)nice) using mouse clicks and arrow keys (without entering numeric PIDs). + +![](https://farm6.staticflickr.com/5581/14819141403_6f2348590f_z.jpg) + +To conclude, these kinds of tools, which efficiently replace basic command line utilities, are like little pearl of usefulness. They are not always easy to find, but once you've got one, you always wonder how you survived for so long without it.

After years of wait, Ubuntu 14.04 with its shiny new kernel finally shipped with proprietary driver compatibility that can be installed easily. This article will guide you through the installation process after quick background of Nvidia Optimus for the unfamiliar readers. For the seasoned destroyer of Xorg configuration, you can quickly jump to the installation section below. + +### Background ### + +To those who aren't aware of Nvidia Optimus, it essentially alternates between using the onboard Intel graphics chipset and the more powerful NVIDIA card on demand using a process referred to as "GPU switching". Its purpose is to prolong battery life in notebooks, allowing the Nvidia GPU to switch off when there is no need for it. The benefits are obvious, allowing say 8 hours of battery life if simply typing in a word processor, or 3 hours if watching HD videos. That is if you are using Windows. + +![](https://farm6.staticflickr.com/5581/14612159387_2e89a52085_z.jpg) + +A couple of years ago I purchased a netbook (Asus VX6), and made the stupid mistake of not checking for Linux driver compatibility because it had never really been an issue before - especially for a netbook sized device. Even if a driver didn't work straight out of the box, I could always get it working one way or another whether installing a proprietary module or using backports. This was a first for me - my device came equipped with an Nvidia ION2 graphics card. + +At the time Nvidia's Optimus hybrid GPU hardware was a relatively new thing, and I did not foresee the limitations I encountered running Linux on this machine. If you're reading this, are experienced with Linux systems and have purchased a notebook in the past for years, you might be familiar with this pain also. + +The [Bumblebee][1] project was until recently as good as it gets in terms of Linux support for hybrid graphics. It was actually possible if configured correctly to utilise the Nvidia card for a desired application via CLI (i.e. 'optirun vlc'), but getting things like HDMI to work was a different story. + +I used the phrase 'if configured correctly' because actually getting it working more often than not just broke your Xorg configuration on first few attempts. If you hadn't used ppa-purge or run 'dpkg-reconfigure -phigh xserver-xorg' before, then I can assure you that tinkering with Bumblebee taught them to you pretty quickly. + +[![](https://farm6.staticflickr.com/5588/14798680495_947c38b043_o.png)][2] + +It's been a very long wait for Nvidia to release Linux driver support for Optimus, and we still don't have the actual support for discrete switching. However, now with Ubuntu 14.04, nvidia-prime and the nvidia-331 driver, one can choose between the Intel or Nvidia card easily. Unfortunately it is still limited further by requiring restarting X11 (achieved by logout and login) for the change to take effect. + +To make this slightly less inconvenient, there is an applet for quick switching, which can I'll get to later, but installation of the driver is a breeze and HDMI works so that's enough to satisfy me. + +### Install Nvidia Optimus Driver ### + +To run through the process quickly, I'll be assuming you've got a fresh install of Ubuntu 14.04 or Mint 17 ready to go. + +Working as a sysadmin, I find 90% of Linux tasks these days quicker via CLI, but this time I recommend simply using the 'Additional Drivers' application that you're probably familiar with for installing proprietary NIC or sound drivers. + +![](https://farm4.staticflickr.com/3886/14795564221_753f9e2d99_z.jpg) + +**NOTE: All commands shown below preceded by ~# need to be run as root. Be sure to either 'sudo su' before running commands, or run with sudo at beginning of command.** + +You can also do it via CLI by installing: + + ~# apt-get install nvidia-331 nvidia-settings nvidia-prime + +followed by a reboot. Make sure you don't have any packages like Bumblebee or other loaded Nvidia drivers, otherwise it'll probably just break your X11. In case you aren't working with a clean install and did previously install Bumblebee etc, run the following before installing nvidia-331 and nvidia-prime: + + ~# apt-get purge libvdpau-va-gl1 bumblebee* nvidia* + +### Switch between Nvidia non-Nvidia Cards ### + +You can switch between Nvidia and non-Nvidia (e.g., Intel) cards by pressing Alt+F2 or typing from terminal: + + ~$ nvidia-settings + +#### NOTE: ~$ means do not run as root user. #### + +Chose the desired card, then log out and log back in. + +![](https://farm4.staticflickr.com/3921/14796320814_de5c9882c2_z.jpg) + +You can also use CLI to set which card to use as default: + + ~# prime-select intel (or nvidia) + +As well as switch cards using: + + ~# prime-switch intel (or nvidia) + +Both commands require restarting X11 to take effect, which can also be achieved by simply logging out and back in. A reboot will also suffice. + +For Ubuntu users: + + ~# service lightdm restart + +For Mint users: + + ~# service mdm restart + +To verify which card is running: + + ~# prime-select query + +And lastly you can install the prime-indicator package from ppa:nilarimogard/webupd8 which allows for a quick switch from the tool bar which restarts your Xserver session for you as well. To install it, simply run: + + ~# add-apt-repository ppa:nilarimogard/webupd8 + ~# apt-get update + ~# apt-get install mesa-utils prime-indicator + +### Summary ### + +In conclusion, it's still not ideal, but at least it's nice and simple with proper proprietary support. Many people often still opt for Bumblebee over this setup because they find using the Nvidia driver only runs their battery dead in no time. For my personal usage this setup is the better way to go as I only use the Nvidia card for HDMI out, which implies that I will have it plugged into power. Otherwise Intel suffices for my portable usage as I don't require anything beyond LibreOffice, Chromium and Terminator on the go. + +If you would prefer the idea of running Intel as default and specifying to run specific applications utilising Nvidia card, instead direct your reading to the many Bumblebee tutorials out there. I advise in the instance of Bumblebee once you finally get it working properly to document the commands and process used to configure for your device as there is nothing worse than doing a clean install 9 months later and forgetting what was done to get it working last time. + +It may also be worthwhile checking out [this script][3] I stumbled across, which serves to easily switch between Bumblebee and Nvidia-Prime, but I must stress that I have not tested it myself. + +Finally, I feel it is a massive shame that it's taken this long to get proprietary support for this cards on Linux and still no support for discrete switching, considering that hybrid graphics appear to be the future for portable devices. Normally AMD are associated with dropping the ball for driver support on Linux, but in my eyes Optimus is by far the worse hardware support issue I have encountered. + +Regardless of whether this is ideal for your usage, it is the easiest way to go utilising that NVIDIA card. Try running the newest Unity on the Intel card alone and decide for yourself whether 2-3 hours battery life is worthy trade off. +

+曾经是很缺乏游戏，“但这状况正发生改变，主要是--但并不是唯一--因为 Valve 的勇敢开创 SteamOS 之举，”他增加道。 + +### '零售货架空间' ### + +“我认为这段时期根本就没有‘杀手级’应用程序，”[Robert Pogson][3] 博客上的观点。“在 Debian GNU/Linux 系统上，有 40K 的软件包，虽然我的 PC 只安装了 3K 的东西，但我一样都不缺。我有多个浏览器、编辑器、编译器/解释器、多个操作平台和像 KVM 这样的虚拟机，我可以根据需要在多个操作系统和不同版本的软件中尽情玩乐。” + +“在局域网内，我可以把多台机器当做一台机器来使用，” Pogson 增加到。“在局域网内我能从任何机器上访问存储在任意节点的资源。还有什么不能满足的吗？” + +"有些说法，“几个专业人士告诉我，在 GNU/Linux 上的视频和图像编辑是有点弱，”他说。 “GIMP 正在比特级别的图像上改进，所以应该不算了。Lightworks（译者注：好莱坞级专业电影编辑软件） 最终会被当做 FLOSS（译者注：自由/开源软件：世界影响研究） 发布，所以视频应该不算。” + +"尽管如此，“在 IT 行业中还有特少数的专业功能软件，”他指出。“很多普通用户几十年都不会使用那些极其特殊的应用程序软件，所有我认为 GNU/Linux 系统已经不不需要什么了。” + +但是真正的杀手在市场上，在零售商店缺乏货架空间，Pogson 断言到。“只要解决这问题，GNU/Linux 必定蓬勃发展。” + +### 'Linux 已经输给 OS X' ### + +Chris Travers，一名工作于 [LedgerSMB][5] 的[博主][4]，有不同的观点。 + +“我认为杀手级应用程序并不是关键问题，”他开始说到。“真正的问题是，虽然跟 BSD 系统一样，Linux 正在占据服务器市场，但在桌面市场 Linux 已经普遍输于 OS X 了。Linux 用户正在寻找开放的桌面系统。” + +Linux “既需要微软的增长势头，又需要 OS X 系统的精致用户界面和引人入胜的细节设计，”Travers 说到。“这些迟早会来有的。” + +### 文档问题 ### + +“Linux 并不是缺少杀手级应用程序” -- "缺少的是一如既往的打磨抛光，" [Hyperlogos][6] 的博主 Martin Espinoza 认为。“根本就没有 Linux 的桌面环境能像 Windows XP 系统那样精雕细琢，更别说是 Windows 7 系统了。” + +"除了可以用臃肿复杂的 GNOME 或 [KDE][7] 的色拉一样的小部件，难道还要用拥有极其可怕的文件管理器和非常原始的面板的 Xface 或 LXDE 吗？" Espinoza 增加道。"GNOME 仅仅只是非常接近 DE。真正的 DE 是十分简洁的，还会隐藏他们的存在。" + +Windows 也仅仅是“表现的比较好，”他断言说。 + +不过，如果 Linux 要获得广泛的接受的话，“最缺的正是游戏，”Espinoza 说到。“如果您把它限定到一款应用程序的话，最需要的很可能仍是 Photoshop 。尽管大家都在谈论 GIMP 已经变得多么多么强大，但它的易用性仍然是个悲催的噩梦；虽然开源社区有些相关的文档，但 GIMP 仍是处在缺乏文档的可怜状态。” + +"GIMP “也许能做 Photoshop 能做的大部分事情，但我很可能并不知道，”Espinoza 的结论。“我想，如果我花了几个小时逛论坛就可以找出如何使用 GIMP 了。这就是大多数开源软件项目失败的地方，包括那些认为他们是真的是有了足够多的说明文档的。” + +### '易用和有技术支持' ### + +SoylentNews 的博主 hairyfeet 定义说易用和有技术支持就是 “杀手级应用”。 + +“嗯，一个新手安装好一个看起来很漂亮的 Linux 发行版系统，它工作得也很正常；但问题是它不会一直正常工作或一直都让人赏心悦目，”他解释到。“第一个更新，哎哟！WPA V2 无线网用不了了。第二个更新呢，像脉冲呕吐一样，声音没了。还有第一个‘升级’？呃，都不需要往下了！” + +“这正是 Linux 欠缺而 Windows 和 OS X 已经具有的：易用性及技术支持，”hairyfeet 结束道。“相同的时段有 15 款以上的 Linux 发行版本跟仅仅只是一款 Windows 发行版本所获得的技术支持生命周期能一样吗？不好意思的说，您们的产品不是同一重量级的 -- 您是拿高中棒球赛跟职业联赛在比较。” + +### 'Windows 8' ### + +最后但并非是不重要的，[Linux Rants][8] 的博主 Mike Stone 提供了一个让人惊讶的建议。 + +“这些年 Linux 缺乏的杀手级应用是 Windows 8，”Stone 打趣说。 + +"说真的，我认为并没有一个特定的应用程序可以被称为'杀手级应用'，“他说，”Linux 需要有更多的主流应用的支持，而这将意味着 Photoshop 和微软的 Office 是必须具有的。值得庆幸的是，微软已经做了最大的努力以使 Office 可以跨平台，至于 Photoshop 的话大多数人并不需要的。" + +Linux "应该是很争议性的话题，上面我所说的 windows 8 仅仅只是个玩笑，"他总结说。“基于 Linux 的应用程序正如火如荼，而当前的 Windows 系统明显不受欢迎。祈祷我们能很快就看到这一变化。” + +-------------------------------------------------------------------------------- + +via: +

Opera Turbo对你的上网体验有些许影响----比如YouTube，可能无法显示视频的缩略图。Opera提供的如此之多设置选项可能令业余使用者手足无措。最后，Opera是闭源软件，作为桌面浏览器它不是被很认可。大多数爱好者仅把它当作一款手机浏览器。 + +### 哪款浏览器适合你？ ### + +有这么多棒极了的选择，很难说哪个适合你。对我来说，由于我每天工作需的一些特定扩展程序，所以我很依赖于Firefox和Chromium。对于一些使用低端机子或是上网本，我的建议是先试试Midori，如果不合适的话，再回头看看Qupzilla。 + +那么Linux上的其它浏览器怎么样呢？比如[Epiphany][9]或是[Konqueror][10]？像这样的浏览器也很棒，但是我对我上面所提到的浏览器印象深刻。上面所列举的都是我经常使用的浏览器，我觉得它们有些地方很出色并且我很开心地向朋友和家人都推荐它们。 + +请务必在下面的评论区域中和我们分享你喜欢什么浏览器，这样其他人也许可以从你的上网方式中得到启发。 +-------------------------------------------------------------------------------- + +via: http://www.datamation.com/open-source/best-linux-browsers-1.html + +原文作者：[Matt Hartley][a] + +译者：[Love-xuan](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[a]:http://www.datamation.com/author/Matt-Hartley-3080.html +[1]:https://www.mozilla.org/en-US/firefox/new/ +[2]:https://www.google.com/intl/en_us/chrome/browser/ +[3]:http://www.chromium.org/ +[4]:http://www.qupzilla.com/ +[5]:https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/ +[6]:https://adblockplus.org/ +[7]:http://midori-browser.org/ +[8]:http://www.opera.com/ +[9]:https://wiki.gnome.org/Apps/Web +[10]:http://www.konqueror.org/ \ No newline at end of file diff --git a/translated/talk/20140724 What are useful online tools for Linux.md b/translated/talk/20140724 What are useful online tools for Linux.md new file mode 100644 index 0000000000..b01b5b189a --- /dev/null +++ b/translated/talk/20140724 What are useful online tools for Linux.md @@ -0,0 +1,148 @@ +适用于Linux的在线工具 +================================================================================ +众所周知，GNU Linux不仅仅只是一款操作系统。看起来通过互联网全球许多人都在致力于这款企鹅图标（即Linux）的操作系统。如果你读到这篇文章，你可能倾向于读到关于Linux联机的内容。在可以找到的所有关于这个主题的网页中，有一些网站是每个Linux爱好者都应该收藏起来的。这些网站不仅仅只是教程或回顾，更是可以随时随地访问并与他人共享的实用工具。所以，今天我会建议一份包含16个应该收藏的网址清单。它们中的一些对Windows或Mac用户同样有用：这是在他们的能力范围内可以做到的。（译者注：Windows和Mac一样可以很好地体验Linux） +### 1.

+================================================================================ +偶尔总会有人指出Linux中的POSIX违规（注：violation此处暂译为违规，若不妥，请修正），通常的回答是修复违规问题，但有时李纳斯·托瓦兹认为POSIX特性是不完整的，至少他们维护Linux特性的情形下是这样的。因此，他们或许应该构建一层POSIX兼容层，即便这个分层会相对较慢和低效。 + +这一次，*迈克尔·凯利斯克*报告了一个影响文件操作的POSIX违规。显然，在多线程操作期间读写文件会导致竞争出现，重写其它操作的改变。 + +关于这是否是POSIX的一个违规存在一些讨论，但到最后又有谁关心呢？数据重写是很糟糕的。在迈克尔提交部分代码去重现这个问题后，讨论的问题集中到该做什么去修复它。但迈克尔确实提出了“Linux从早期开始就与UNIX不一致。（如在1992年版的史蒂夫的APUE的191页讨论到fork()操作后在父进程与子进程之间文件偏移量的共享问题。尽管史蒂夫没有显式地讲清楚一致性的保证，但缺乏这个保证的推论这里的讨论可能有些没意义。）”的观点。 + +艾尔·维洛和李纳斯一起设法解决这个修复。李纳斯尝试引入一个简单的互斥量去锁住文件，以便写操作无法互相重写。艾尔提出了自己的改进以改善李纳斯的补丁。 + +李纳斯一度解释过这个故障自身的历史。显然，从前这个用来告诉系统去哪里写文件的文件指针已经被锁在一个信号量中，所以只有一个进程可以在某一时刻对这个文件做任何操作。但是，他们从中拿走了这个信号量，以便在任何时候可以适应设备文件和其它非常规文件，因为当用户被禁止写入其中时它们就会陷入竞争状态。 + +这就是错误的由来。那时候，它悄悄通过了检查，未被发现。因为实际上对常规文件的读写仍然由内核自动处理。只有文件指针自身可以避免同步。而且，因为高速线程化的文件操作是一个非常罕见的需求，所以对任何人来说都需要很长时间才能遇到这个问题并报告它。 + +一个有趣的小细节是当李纳斯和艾尔在寻找一个修复方案时，艾尔一度抱怨李纳斯采用的方法并不能支持确定的架构，包括*ARM*和*PowerPC*。李纳斯的回应是“我怀疑关心这个是否有意义。[...]如果使用ARM/PPC架构的人停止抱怨，他们可以往gcc中加入struct-return的支持。” + +看到这些问题突然产生并得到处理通常是很有趣的。在某些情况下，这个修复的部分工作必须在内核中进行，部分在GCC中，部分在其它地方。在这个特例里，艾尔认为整个事情都应该在内核里处理，他在灵感的激发下往补丁中写入了自己的版本，李纳斯也接受了。 + +*安迪·克伦*则想为*perf*增加底层CPU事件支持。问题在于这可能会导致大量的底层事件，而且会因CPU的变化而改变。即使为了所有类型的CPU把可能的时间都存储在内存里，也可能会显著地增加内核的运行大小。因此，把这个信息硬编码进内核的方法是有问题的。 + +他也指出*OProfile*工具依赖于这些时间的公开可用列表，尽管他表示OProfile开发者并非总维持他们的列表与最新的可用版本一致。 + +为了解决这些问题，安迪提交了一个补丁，允许perf识别在给定的系统上为特定的CPU需要那种事件列表，并自动从起始位置下载这个列表的最新版本。然后perf可以解释这个列表并分析其中的事件，不会使内核负载过重。 + +有各种各样对安迪代码的反馈，其中大部分涉及到应该在哪个目录下保存事件列表和文件如何命名。这份代码本身的特性似乎得到了很好的回应。一处细节证明了安迪的代码比其他人的更有争议，就是将列表下载到用户家目录下的一个子目录。安迪表示如果不这样做的话，用户可能会以系统管理员的身份去下载事件列表，这会是危害安全的操作。 + +萨沙·莱文最近发布了一个脚本来从堆栈转储中把*十六进制的偏移量*翻译成有意义的指向内核源码文件的行号。因此诸如“ffffffff811f0ec8”形式的十六进制表示可以被翻译成“fs/proc/generic.c:445”。 + +然而，结果表明李纳斯·托瓦兹正打算从堆栈转储中移除十六进制偏移量，具体原因是他们难以理解。所以萨沙的代码看起来过时了。【译者注：程序媛，伤不起！】 + +他们在这个问题上纠结了一番。起初，萨沙打算依赖存储在System.map文件里的数据区补偿，但李纳斯指出包括他在内的有些人并不会保留System.map文件。李纳斯推荐使用/usr/bin/nm从编译好的内核文件中提取符号表。 + +所以，似乎萨沙的脚本可能确实为调试堆栈转储提供了有意义的文件和行号，假设堆栈转储提供足够的信息去完成计算。

+然后，我们又见证了虚拟机技术的商品化。使用 Amazon 云主机或者 VPS 的用户也许永远不用在裸机上部署 Linux。随着混合云和私有云的日益普及，甚至很多企业级的系统管理员都不需要在裸机上部署 Linux——登录 Web 管理界面，一次性就能搞定不止 5 台 Apache 虚拟机。 + +时下最新的两个趋势（一个是配置管理，另一个看起来很前沿（其实一点儿都不前沿）—— 像 docker 这样的部署工具包）隐藏了更多 Linux 底层技术细节。每当客户要求我们在 [OlinData][1] 上配置 Linux 机器时，我们的第一个动作就是安装配置 [Puppet][2]。有了功能强大值得信赖的 Puppet 模块，手工配置也更快更简单了。 + +例如，我可以这样使用 Puppet 在新机器上安装 Apache: + + node 'web01.olindata.com' { +

### + +就算有更新的工具对我们隐藏更多的技术细节，坚持 Linux 训练对系统管理员来说仍然很有价值。了解基础知识很关键，这些抽象高级工具把管理员从旧的任务中解放了出来，那么系统管理员就应该强化自己使用这些高级工具的能力。熟悉高级工具对系统管理员提升层次来说很关键，这会迫使系统管理员不断练习编写代码一类的能力，并借此发挥这些新玩意儿更大的潜力。 + +底层 Linux 技能需求会完全消失么？当然不会。除了商业服务器部署之外，Linux 还有大量其他用途。同时，人们也从底层操作知识中获益颇丰。最重要的是，如果你的简历上体现出了这些技能，我（还有很多其他老板）总是会优先选择你，而不是那些尚未掌握这些技能的候选人。因为你也不知道啥时候你就用上这些技能了！ + +---------- +![Walter Heck —— 荷兰开源培训顾问公司 Olindata 公司

milestone版看起来“很早期”，到现在距离1.0发布也只有两个月时间了。因此，安卓0.9被打上了“beta”的标签。在移动操作系统之路的另一边，苹果在一个月前已经发布了iPhone的第二代产品——iPhone 3G。第二代的iPhone搭载了第二代iPhone OS。苹果同样发布了App Store应用商店并且已经开始接受应用提交。谷歌在追赶的道路上还有很多事情要做。 + +谷歌抛弃了很多在Milestone 5中引入的UI设计。所有设计都回炉重造进入全彩，白色方形图标背景被抛弃。尽管0.9还是一个模拟器版本，相比与安卓发布版来说看起来还是有点熟悉。安卓0.9有一个可用的桌面式主屏幕，一个特有的应用抽屉，多主屏，更多的应用程序，以及全功能（暂仅限第一方）小部件。 + +Milestone 5中似乎没有计划支持安装21个以上的应用，但在安卓0.9中有一个垂直滚动的应用抽屉，可以通过屏幕底部的灰色标签打开。那时候，应用抽屉真的只是个抽屉。除了作为一个按钮使用，灰色标签还可以跟随你的手指被向上拉起，就像通知面板被拉下来那样。还额外添加了一些应用，像闹钟，计算器，图片，信息，以及照相机。 + +这是第一个可以完全自定义主屏幕的版本。长按应用或小部件可以拖动它们。你可以把应用从抽屉中拖出到主屏幕快捷方式或长按一个已经存在的主屏幕快捷方式来移动它。 + +安卓0.9提醒我们谷歌那时候并不像今天这样优于设计。实际上，当时安卓的部分设计工作外包给了其它公司。你可以从时钟小插件看出一点端倪，它包含了“MALMO”字样，它是设计公司[The Astonishing Tribe][2]的所在地。 +

+“文件夹”是快捷方式标题下的一个选项，尽管它并不是任何东西的快捷方式。一旦创建了一个空文件夹，图标就可以被移动进去并重新排列。不像今天，那时候的文件夹里有什么并不反映在文件夹图标上，它一直是一个简单的，白色的，看起来空空的文件夹图标。 + +0.9同样是第一个拥有系统级别复制/粘贴支持的安卓版本。长按任意文本框会唤出一个对话框，从而让你保存或撤销剪贴板中的文本。iOS直到近两年后才支持复制/粘贴，所以在一段时间内，这是安卓的特色之一——以及许多网络争议的源头。 +

+Soundcloud2000非常容易使用。有些人甚至会说简单。我喜欢它的庄重以及三位作者和贡献者的努力。如下启动它： + + $ soundcloud2000 + +这里，你将看到一个闪屏： + +![](https://farm4.staticflickr.com/3919/14658085706_71c9094e4f_z.jpg) + +接着是歌曲列表： + +![](https://farm4.staticflickr.com/3888/14494626757_3e788482d5_z.jpg) + +您可以通过上下键滚动列表，回车播放一首歌曲，空格键是暂停/恢复，左右箭头键是快进/快退。正如你所看到的，没有什么突破性的但绝对符合人体工程学。 + +如果随机列表太长无法滚动完，你有一个选项来查看所有曲目，用户通过点击'u'键接着输入自己的名字。 + +![](https://farm4.staticflickr.com/3861/14494436719_b5536f7b67_z.jpg) + +这可能是Soundcloud2000的主要默认之一。而导航没有优化过，我寄予厚望的改善和支持的软件还是很年轻的。 + +### 红利 ### + +另外一个额外的红利：如果你喜欢在终端上使用SoundCloud的想法，但不想安装任何额外的软件（也许你不能），我劝你去[cmd.fm][6]。该网站是一个伪装的SoundCloud，因为它隐藏在一个shell接口后。 + +[![](https://farm6.staticflickr.com/5580/14494448218_a16b05e3ee_z.jpg)][7] + +输入“help”可以得到命令列表，这比Soundcloud2000长很多。比如，我看到： + +- _genres to list all genres +- _play random to play a random track +- _pause to pause the current track +- _playlist new to make a new playlist +- _loop to loop current track +- _cinema to watch and ASCII version of Star Wars which completely blew my mind. + +它甚至支持通过tab键自动完成流派 + +最后，Soundcloud2000的确是一个整洁的程序。我们可以原谅其目前的缺陷，因为它还年轻。我真的希望它会成长，并包含更多的功能（并从潜在的cmd.fm得到的灵感）。 + +如果您喜欢这个主意，我邀请你支持程序员，如果你喜欢这类举措，请支持[Music Hack Day][8]，这其中混合了软件开发和音乐。 + +你认为在命令行下使用SoundCloud怎么样？让我们在评论中知道你的想法。

+Linux命令行的强大在于其灵活及多样化，各个Linux命令都带有它自己那部分命令行选项和参数。混合并匹配它们，甚至还可以通过管道和重定向来联结不同的命令。理论上讲，你可以借助几个基本的命令来产生数以百计的使用案例。甚至对于浸淫多年的管理员而言，也难以完全使用它们。那正是命令行小抄成为我们救命稻草的一刻。 +

+最为一个选择，也可以通过另外一个命令来访问你最爱的命令行小抄。那就是，使用[cheat][2]。这是一个命令行工具，它可以让你从命令行读取、创建或更新小抄。这个想法很简单，不过cheat经证明是十分有用的。本教程主要介绍Linux下cheat命令的使用方法。你不需要为cheat命令做个小抄了，它真的很简单。 + +### 安装Cheat到Linux ### + +首先，如果你还没有Git，那么就安装一个吧： + + $ sudo apt-get install git (Debian-based system) + $ sudo yum install git (RedHat-based system) + +同时，安装[Python包安装器pip][3]。 + +最后，使用下列命令来安装cheat。 + + $ sudo pip install docopt pygments + $ git clone https://github.com/chrisallenlane/cheat.git + $ cd cheat + $ sudo python setup.py install + +### 配置Cheat ### + +cheat命令并不需要太多配置。 + +一个推荐的配置是启用命令行补全功能。那样，当你查询一个小抄时，就可以使用[TAB]键来自动补全你想要查看的命令名称了。以下操作可以启用bash下的自动补全功能。 + + $ wget https://github.com/chrisallenlane/cheat/raw/master/cheat/autocompletion/cheat.bash + $ sudo cp cheat.bash /etc/bash_completion.d/ + +他们也提供了用于其它shell的自动补全脚本，像zsh和fish也有。 + +另外一个要做的事是定义EDITOR环境变量。该变量应该指向创建或更新小抄时你想要用的文本编辑器。例如，如果你想要使用Vim编辑器，那就把下面的内容放进~/.bashrc。 + + export EDITOR=/usr/bin/vim + +注销并重新登录进来，以激活自动补全功能并更新.bashrc。 + +### Cheat基本用法 ### + +cheat命令一个很酷的事是，它自带有超过90个的常用Linux命令的内建小抄。查看可用的小抄列表： + + $ cheat -l + +![](https://farm3.staticflickr.com/2932/14754370585_7133cbbc8c_z.jpg) + +要访问某个指定命令的小抄，只要运行cheat命令，后面跟上该命令的名称： + + $ cheat + +![](https://farm4.staticflickr.com/3899/14567722899_8b86c312ca_z.jpg) + +你可以通过使用“-s”选项，在所有小抄中搜索包含有指定关键词的内容： + + $ cheat -s + +在许多情况下，小抄适用于那些正派的人，而对其他某些人却没什么帮助。要想让内建的小抄更具个性化，cheat命令也允许你创建新的小抄，或者更新现存的那些。要这么做的话，cheat命令也会帮你在本地~/.cheat目录中保存一份小抄的副本。 + +要使用cheat的编辑功能，首先确保EDITOR环境变量设置为了你默认编辑器所在位置的完整路径。然后，复制（不可编辑）内建小抄到~/.cheat目录。你可以通过下面的命令找到内建小抄所在的位置。一旦你找到了它们的位置，只不过是将它们拷贝到~/.cheat目录。 + + $ cheat -d + +---------- + + /usr/lib/python2.6/site-packages/cheat/cheatsheets + +---------- + + $ cp /usr/lib/python2.6/site-packages/cheat/cheatsheets/* ~/.cheat + +现在，你可以使用“-e”选项来创建或更新一个小抄了： + + $ cheat -e openssl + +正如你所能想象的，cheat的编辑功能十分有用，可以帮助你剪裁本地小抄库以满足你的需要。如果你深信知识分享，贡献你的小抄到cheat命令的[官方Git仓库][4]中，你会更加受欢迎，这样大家都能从中受益。 + +-------------------------------------------------------------------------------- + +via:

+================================================================================ +极少Linux桌面像GNOME 3一样饱受争议。自发布以来，它被奚落，被挖苦，还被痛恨。事情是，它实际上是一个很不错的桌面。它牢固、可靠、稳定、优雅、简洁……而且带有一些小的调整和附加的东西，它可以做成市面上最高效、最友好的桌面之一。 + +当然，什么才是高效而又/或者是用户友好的桌面呢？那取决于观念——每个人都有的东西。归根到底，我的目标是帮助你快速访问你要用到的应用和文件。简单吧。不管你信不信，将GNOME 3一步一步变成更为高效而又用户友好的世界是一项十分容易的任务——你只需要知道哪里去查看以及做些什么即可。在这里，我会引领你去往正确的方向。 + +我决定从这里开始着手这个事情，首先安装一个干净的[Ubuntu GNOME][1]发行版开始，该安装包含有一个GNOME 3.12桌面。在以GNOME为中心的桌面准备好后，就该开始对它进行微调了。 + +### 添加窗口按钮 ### + +处于一些未知的原因，GNOME的开发者们决定对标准的窗口按钮（关闭，最小化，最大化）不屑一顾，而支持只有单个关闭按钮的窗口了。我缺少了最大化按钮（虽然你可以简单地拖动窗口到屏幕顶部来将它最大化），然而也可以通过在标题栏右击选择最小化或者最大化来进行最小化/最大化操作。这种变化仅仅增加了操作步骤，因此缺少最小化按钮实在搞得人云里雾里。所幸的是，有个简单的修复工具可以解决这个问题，下面说说怎样做吧： + +默认情况下，你应该安装了GNOME优化工具。通过该工具，你可以打开最大化或最小化按钮（图1）。 + +![Figure 1: Adding the minimize button back to the GNOME 3 windows.](http://www.linux.com/images/stories/41373/gnome3-max-min-window.png) +Figure

3的最佳特性之一，就是shell扩展，这些扩展为GNOME带来了全部种类的有用的特性。关于shell扩展，没必要从包管理器去安装。你可以访问[GNOME Shell扩展][2]站点，搜索你想要添加的扩展，点击扩展列表，点击打开按钮，然后扩展就安装完成了；或者你也可以从GNOME优化工具中添加它们（你在网站上会找到更多可用的扩展）。 + +注：你可能需要在浏览器中允许扩展安装。如果出现这样的情况，你会在第一次访问GNOME Shell扩展站点时见到警告信息。当出现提示时，只要点击允许即可。 + +令人印象更为深刻的（而又得心应手的扩展）之一，就是[Dash to Dock][3]。 +该扩展将Dash移出应用程序概览，并将它转变为相当标准的停靠栏（图2）。 + +![Figure 2: Dash to Dock adds a dock to GNOME 3.](http://www.linux.com/images/stories/41373/gnome3-dash.png) +Figure 2: Dash to Dock添加一个停靠栏到GNOME 3. + +当你添加应用程序到Dash后，他们也将被添加到Dash to Dock。你也可以通过点击Dock底部的6点图标访问应用程序概览。 + +还有大量其它扩展聚焦于讲GNOME 3打造成一个更为高效的桌面，在这些更好的扩展中，包括以下这些： + +- [最近项目][4]: 添加一个最近使用项目的下拉菜单到面板。 +- [搜索Firefox书签提供者][5]: 从概览搜索（并启动）书签。 +- [跳转列表][6]: 添加一个跳转列表弹出菜单到Dash图标（该扩展可以让你快速打开和程序关联的新文档，甚至更多） +- [待办列表][7]: 添加一个下拉列表到面板，它允许你添加项目到该列表。 +- [网页搜索对话框][8]: 允许你通过敲击Ctrl+空格来快速搜索网页并输入一个文本字符串（结果在新的浏览器标签页中显示）。 + +### 添加一个完整停靠栏 ### + +如果Dash to dock对于而言功能还是太有限（你想要通知区域，甚至更多），那么向你推荐我最喜爱的停靠栏之一[Cairo Dock][9]（图3）。 + +![Figure 3: Cairo Dock ready for action.](http://www.linux.com/images/stories/41373/gnome3-Cairo-dock.png) +Figure 3: Cairo Dock待命 + +在Cairo Dock添加到GNOME 3后，你的体验将成倍地增长。从你的发行版的包管理器中安装这个优秀的停靠栏吧。 +
