+================================================================================ +### “云”简介 ### + +不论是报纸、在线资讯、播客、科技博客、科技门户网站，甚至是电台和电视。“云计算”永远都是人们津津乐道的主题。 + +然而，因为“云计算”包含了太多的东西，现在并没有一个明确的定义，所以你认为“云计算”应该是什么呢？ + +> **云计算** 过去常常被当做是网络计算的一个模型，网络计算就是把用户程序或者是应用运行在一个联网的服务器或是一个服务器集群，而不是像个人电脑、平板以及智能手机这一类运算设备。比如像传统的client-server (客户机-服务器模型) 和老一代的大型机，^[1] 用户通过连接服务器来执行一项任务。这和“云计算”是不同的，“云计算”是利用虚拟化的技术，把运算进程运行在一个或多个服务器上。利用虚拟技术，越来越多的物理化的服务器被配置和划分成多个独立的“虚拟”服务器，每个服务独立运行，对于用户来说，就像是运行在一个独立的物理服务器上一样。虚拟服务器本质上还是从他们的物理服务器中分离出来的，由于这种灵活的配置方式，使得人们可以按照意愿移动服务器和按比例分配资源而不影响最终的用户体验。计算机资源已成“颗粒”，给用户和管理人员提供方便，包括提供按需自助服务，支持更广泛的跨平台之间的访问，资源共享，快速重新部署，可被监控与量测服务。^[2] + +以上引用摘自维基百科。 + +在过去，我们要么用哑终端连接大型电脑主机，要么近年来使用桌面电脑连接运行在内部服务器上的应用，就像网站连接数据库一样。 + +现在，所有桌面、应用和服务器的管理都已经本地化，都需要来自它们所属公司的技术支持。 + +然而这只对软件公司等少数的公司有利，却对其他的一些商业公司不利，比如说银行、保险公司和石油公司。信息技术公司没有银行的职能，就好像是做餐饮的钻不出地下的石油一样。 + +大公司早已把很多服务外包给专业的公司。例如，让餐饮公司为他们的员工提供食堂，以及我们所熟知的离岸呼叫中心处理银行业务的客户电话。 + +IT 行业的很多服务也逐渐转向外包，许多的技术支持和开发的业务都被打包给中国、印度、马来西亚和东欧。 + +云计算与传统的典型模型有很大不同的一方面在于虚拟化，这种虚拟化的技术把服务运行于虚拟服务器上，服务器可以被放置在同一个地方或者是相隔千山万水，但是，这并不重要，你也不用担心，因为那不是你该担心的事情。 + +> 现在，“云计算”已经成为云计算基础设施的简称。^[4] 这个术语来源于早年一些网络工程师用云状的符号表示那些对他们来说未知的网络。^[5] 后来，营销者普及了这个云的概念，指的是软件、平台和一些可以买卖的基础设施。比如，远程登录互联网。 + +因此，这篇文章讲述了和云相关的所有，对于linux的用户来说，这意味着你想用它做什么和它能为自己做些什么，当然，这有可能也会给我们造成一些误区。 + +从一个终端用户和家庭使用者的角度来看，云计算最基本的就是提供在线服务。 + +所以，让我们来说一说云能到底能给每一位linux用户提供些什么有用的服务？ + +### 电子邮件 ### + +当你读到这里的时候，如果你还没有一个电子邮箱，我只能说你OUT了。 + +据PC杂志顾问统计分析，截至2014三月份，电子邮箱的用户最多的前六名分别是Outlook、GMail、Yahoo、icloud、AOL和GMX。 + +### 办公套件 ### + +和电子邮件客户端一样，对于每个人来说，另一个最常用的工具之一就是办公套件。 + +在以前，当人们刚刚进入电脑世界的时候，买一个电脑会带回一个超大型的机器和半打子CD，刻着几个没用的 Microsoft Works ( 微软工作软件 )。 (LCTT译注：Microsoft Works Mirosoft Works是微软的一种家用综合软件，它主要面向低端的家庭用户,提供基本的能提高生活效率的工具,比如提供简单的文档处理、数据库、电子表格的入门级办公包功能。) 微软工作软件是一个廉价，而且无用到几乎要被砍掉的微软office版本。 + +而现在，你甚至不需要在你的电脑上安装任何的办公套件，即便是有LibreOffice和Kingsoft这样好的软件供选择。 + +最好的选择当然是Google Docs和Office 365。对于Office 365能否很好的运行于Linux平台，这篇来自2012期专业电脑的文章似乎说明了这个问题。 + +![](http://www.linuxnews.pro/wp-content/uploads/2014/06/office365_1.png) + +有人说这怎么可能呢，我不相信，所以，我注册并登录了Office 365，想看看到底是什么情况。 + +注册，可以免费试用一个月，并且会赠送包括Word、Excel、和Outlook等一些在线应用。 + +![](http://www.linuxnews.pro/wp-content/uploads/2014/06/office365_2.png) + +一切看起来都挺好，我打开了Microsoft Word，选择了一个模板来使用，当然根本就没有打开成功。 + +Office 365 并没有很好的支持linux设备，况且，说实话，你也不需要这东西。so，咱们继续。 + +![](http://www.linuxnews.pro/wp-content/uploads/2014/06/office365_3.png) + +Google Docs对于一般的办公支持非常完美，它能完成很多的事情，并且有很多的模板针对文字处理，演示工具，电子表格等。即使它始终也代替不了Excel，因为他并没有成百上千的开发人员为其创建宏和编写VBA脚本。 + +![](http://www.linuxnews.pro/wp-content/uploads/2014/06/zoho_1.png) + +另一个可供选择的办公套件是Zoho。 + +和Google Docs一样，Zoho也包含有文字处理工具，演示程序，电子表格程序和电子邮件。 + +此外，还有很多金融和客户管理系统。 + +![](http://www.linuxnews.pro/wp-content/uploads/2014/06/zoho_2.png) + +这个工具的界面看起来真的很简洁，很棒。 + +它和Google Docs和Zoho这些在线服务一样，给予了人们相互协作的便利。 + +很多文档被不同的人分享，然后在不同的地方被不同的人修改完善。 + +这里会给出一些理由来帮助你从Google Docs和Zoho中选择一个适合你的办公套件。 + +### 在线文件存储 ### + +Google Docs和Zoho给我们提供了其他一些很好的服务，就是很好的线上存储能力，你们可以线上存储很多文档和创建很多文件。 + +也有一些其他的服务,比如说Dropbox,仅仅只提供在云存储服务。 + +像Dropbox这样的云存储的好处是如果你的东西被偷了或者是不小心房子着火了，而这时，你仍然有一份离岸备份是安好无缺的。你仍然可以在任何地方获取你的文件。 + +Dropbox对于前2G的容量是免费的，如果你还有更多的东西要存储，每天还有更多的事情要做，每个月只要9.9美刀，你就能拥有100G的存储空间，另外，Dropbox也提供商务版本，每个月15美刀。 + +当然，并不是说Dropbox没有可替代的方案，这个网站也提供了很多很好的一些在线备份的方案。 + +### 相册 ### + +自从有了数码照相机和智能手机，现在越来越多的人们利用存储卡来保存照片。 + +我相信肯定有人因为电话坏了而丢失照片，因为他的照片是存储在电话上的，而不是其他的存储设备，甚至，有些因为丢失了电话而丢失了他们孩子的运动会照片或者是其他一些具有纪念意义的照片资料。 + +丢失电话肯定不是什么好事情，如果你放机灵一点，情况可能要好一点，因为很多人的电话和email，facebook，Twitter的账户是同步的，甚至在线存储也是。 + +当然，丢失手机时，我们可以更改以上那些账户的密码，可是丢失的照片却是再也找不回来了，这让人有一点点伤心。 + +备份资料到电脑当然是一种很好的解决方法，不过要是你的笔记本哪天不小心坏了，你也只能变得一无所有，从头再来。 + +在线照片存储的网站是一个很好的资源，因为他们不止要保证你的照片的安全，你也可以很方便的把照片分享给你选择的人。省去了那些把同样的照片做无数次的拷贝分别发给妈妈，奶奶，妹妹，阿姨和岳母等各种亲戚朋友的麻烦。 + +我常用的一个是谷歌的Picasa相册工具，但是大家也可能听说过像Flickr这样的网络相册。 + +Lifehacker给出了最好的5个网络分享的相册。 + +请记住，他们仅仅是被称作相册分享工具，并不是说你一定要分享，你也可以自己保留他们。 + +### 音乐 ### + +我得到的第一个唱片是20世纪80年代初“Adam and the Ants”的"Kings of the wild frontier"里的一个12英寸的碟子。 + +在20世纪80年代后的很长一段时间里，唱片逐渐被磁带所取代，就好像是我积累了很多的磁带以后，磁带却被CD所取代。 + +后来，成百上千的CD和MP3越来越普遍，直至成为了一种潮流。 + +而音频流媒体始终也跟着潮流一起进步，比如像Spotify。 + +Spotify是一个免费的软件，但是里面包含广告，对于使用的人们而言，它就像是一个你可以定制的私人电台，当然你也可以交月费来去除广告。 + +Grooveshark和last.fm也有提供很多相似的服务。 + +Techradar给出了7种Spotify的替代方案。 + +### 电影 ### + +小飞象 (Dumbo) 是我最早在电影院看的一部电影。而我最早接触录像是“Krull”，它讲述了Dulph Lundgren的年轻时候的经历，录像的格式是Beta Max。(当时我的邻居就有一个) 。 + +有一天，爸爸从收音机租赁处带回来一个录像机，我和我的姐姐就轮流去录像店租带子看。我清楚的记得，我第一次租的带子名字叫“黑洞”(The Black Hole)。 + +直到有声电影的出现，你就不得不拿一个很大的东西来装电影带子，所以有些天才就发明了DVD，甚至是制造出了蓝光碟片。 + +现在，流媒体已经充斥着我们生活的每一天，要是你有个牛X的网络就更完美了。 + +其中，最出名的流媒体提供商是Netflix和Lovefilm (Netflix和Lovefilm都是在线的影片租赁公司)。 + +linuxnews给了我们一些更好的选择来替代Netflix，因为并不是所有的服务都能无缝的在linux上工作，包括Netflix。 + +### 游戏 ### + +继音乐，电影搬到线上以后，游戏也登上了在线的舞台。 + +对游戏来说就要困难一些，因为音乐只占用很少的带宽，而电影的要求相对高一点，但是也仅仅是为了得到一幅清晰的画面。 + +游戏始终需要很高的帧速支持，不然即使你手上有一个很好玩的游戏，可能也不值得去尝试。 + +当前，很多游戏服务商都有提供基于云的游戏，包括OnLive和StreamMyGame也有提供。 + +linuxnews给出了6个和OnLive竞争的游戏服务提供商。 + +### 争议 ### + +云计算也并不是没有争议。 + +首先，最大的问题就是安全问题，如果有人进入了你的在线存储空间和你的电子邮箱，并盗取了你的个人信息。 + +那么在线存储你都会存些什么呢？像Megaupload.com这样的网站，上面都有很多有价值的客户资料。 + +Megaupload.com这个网站本来提供的大容量文件的存储，而问题却是，很多人用它来分享一些有版权的资料，美国的当局就不依不饶的下来检查，所以这个服务被迫关掉了。 + +现在，因为很多人丢失了资料，当局的这样做也是无可厚非的，但是对于那些没有做错事的人来说，他们的数据资料也丢失了，美国当局拒绝还给本人。 + +最后给出了一个服务正在维护的答复，如果你的电子邮件停了一天你能应付，那么3天呢？甚至是一个月你还能应付得了吗，那么你也就只能任由服务提供商摆布了。 + +很多大公司已经取回了丢失的数据，但是仍然有很多心脏病漏洞(openssl的heartbleed安全漏洞)的消息在，这是ssl应用多年中发现的一个重大的安全漏洞。 + +所以说，如果你用了别人提供的在线服务，那么你必须信赖他们技术支持人员，你也必须相信他们不会出现被黑客攻击，硬件故障，缺乏备份和无法恢复系统这样的情况。 + +### 总结 ### + +现在云计算早已成了充斥着在线服务的主题，你的浏览器就是一个客户端，连接世界上任意一个地方的服务器或者是服务器集群。重点是你没必要去关注，而且你也不需要知道。 + +一般来说，我们仅仅触及的是它的表面，所有我们每天接触到的云，对于我们大多数人来说甚至都不用去关注它。 + +至于说云到底是怎样影响着每一位linux用户，事实去证明是有很多的。 + +云到底是好是坏？又或许什么都不是。每一种服务的好坏都要看它的优势。 + +或许云仅仅是营销人员炒起来的一个概念，也只会让技术新闻感到兴奋。是否还有人记得我们一直在用的“Web 2.0”？ + +感谢您的阅读。 +

+================================================================================ + +> GCC邮件列表中在争论GCC是否应该接受收费插件，但是认为GCC是一个免费软件开发的媒介的论调占得了上风 + +Gcc以及它在模块化方面的缺失又一次作为一个问题被提出来，并且和市场上的新的编译器LLVM做了对比。GCC巨大而古老：5百万行代码，30年研发时间，并且还在继续增长。相比较而言，LLVM更加年轻，更加模块化，并且允许所有的语言都作为一个模块添加进去。 + +LLVM的核心是‘开放源代码’。GCC是反著作权（copyleft）代表，是严格的免费软件，她不允许以任何形式收费的插件的代码进入到GCC的代码中。争论的一种意见，正如Eric Raymond说的，“FSF不可能既阻止持有所有权的供应者添加他们的插件到一个免费编译器中，又让这个编译器得到发展。就像马儿已经偏离了跑道，反对插件策略的战略目标已经彻底的失败了”。 + +LLVM已经被苹果公司采用作为OS X和苹果硬件上GCC的替代品，并且正在变得流行起来，特别是在BSD系列操作系统的用户中间。LLVM的拥护者推测LLVM将会在更广阔的应用程序和移动设备开发市场上成为GCC的替代者。GCC的反对者们的观点是GCC太过复杂，并且开发者们必须遵守她的‘反著作权（copyleft）’。这限制了那些不想在‘反著作权（copyleft）’许可证下发布他们的语言或者软件产品。作为典型，苹果公司有一个很长的厌恶免费软件的历史。他们也不允许遵守‘反著作权（copyleft）’的软件通过他们的App Store发布。 + +LLVM和GCC之间的争论其实是GNU/Linux和BSD系列、开放源代码和免费软件之间历史差异的翻新版。开放源码的开发者允许代码被以任何形式的使用，免费或者维持版权。免费软件则严格地规定，代码或者针对代码做的更新，必须保持永久免费。免费软件的支持者认为完整的‘反著作权’授权有助于GCC的发展，并且已经将Linux和免费软件带到一个其他方式无法到达的高度，同时保证了免费软件不会被收购或者堕落成商业利益。开放源码的支持者则认为开放源码更加的自由，因为使用这没有受到限制，他们可以随意使用，包括开发非开源的版本。 + +GNU编译器集合（GCC）一直是免费软件发展的关键。编译器是稀有且昂贵的商品，版权软件公司也充斥着对不符合标准的特性的需求。让软件兼容不同的机器和操作系统是一个非必需的复杂任务。GCC作为第一个真正免费的跨平台编译器，简化了这个过程。 + +GCC对于软件开发者和移动设备开发者来说也是一个划时代的产品，而不仅仅对于那些免费软件概念提出者。GCC不但免费和可移植，她跨越不同硬件架构的普遍性和公用性使得更加容易做到软件的兼容性、鲁棒性和一致性。这和John Gilmore，Michael Tiemann和David Henkel-Wallace在开发GCC时发现的一样。这也是Cygnus Solutions公司主要的卖点，Cygnus Solutions是第一家靠卖免费软件赚钱的公司。[译注：Cygnus Solutions是John Gilmore, Michael Tiemann and David Henkel- Wallace创办的公司，同时也是GNU几个主要产品的贡献者] + +LLVM和GCC之间主要的技术差异集中在组成‘前端’，‘中端’，‘后端’的模块分割。‘前端’用来翻译特定的语言。‘中端’对翻译后产生的代码进行优化。‘后端’将优化后的代码转化成特定硬件架构的机器码。LLVM将这些模块分割成不同的实体，但是由于语义的和历史的原因，GCC模糊了这些模块之间的界限。 + +对于一个免费软件项目，添加一种新的语言或者架构到GCC也许是一个非常困难的过程，添加有版权的插件也是不允许的。由于模块间界限非常不明确，最容易的添加方法就是让添加的特性遵循免费软件许可证。最初的开发者也许想保持代码的封闭和版权，但最后不得不将代码以免费软件发布。早期的C++以及Objective C就被认为是其中典型的例子。 + +与此相反，LLVM允许，甚至也许可以说是鼓励添加和发展版权语言和架构，比如英伟达基于Clang和LLVM的对于GPU开发的NVCC。NVCC的源代码是免费软件或者开源软件开发者获取不到的。 + +Richard Stallman[对这方面的演讲中][1]旗帜鲜明地宣布：“在免费软件运动中，我们为自由而战。免费软件的的价值观从根本上就和开源软件不同，后者以写‘更好的代码’为终极目标。如果GCC从免费的编译器变成非免费的编译器，她将不再能够达成自由的目标。 + +“Clang和LLVM的开发者不认可我们的价值观和目标，所以得出了跟我们不一样的结论。他们反对我们采取的捍卫自由的措施，因为他们只看到这对他们造成的不便，却没有看到（或者不关心）他们真正的需求。我猜测他们把他们的工作定义为‘开源’，并且漠视自由。” + +GCC开发者们不可能在许可证的条件上妥协。LLVM在某些行业的部门非常流行，因为它很年轻很新，在编程语言的浪潮中跳跃式发展着。流行的风向着更加开放奔跑，GCC决心跟商业利益死磕也许是这个长期演进路上的一大助力。Unix公司们从80和90年代的Unix战争中学到了一些东西。语言和操作系统都是工具，它们最好是开放和共享的。GCC是免费软件，不属于任何人。 +

+10个关于linux中Squid代理服务器的实用面试问答 +================================================================================ +不仅是系统管理员和网络管理员时不时会听到“代理服务器”这个词，我们也经常听到。代理服务器已经成为一种企业常态，而且经常会接触到它。它现在也出现在一些小型的学校或者大型跨国公司的自助餐厅里。Squid（常被视作代理服务的代名词）就是这样一个应用程序，它不但可以被作为代理服务器，其同时也是在该类工具中比较被广泛使用的一种。 + +本文旨在提高你在遇到关于代理服务器面试点时的一些基本应对能力。 + +![Squid Interview Questions](http://www.tecmint.com/wp-content/uploads/2014/07/Squid-Interview-Questions.png) + +以下为面试问答的内容 + +### 1. 什么是代理服务器？代理服务器在计算机网络中有什么用途？ ### + +> **回答** : 代理服务器是指那些作为客户端和资源提供商或服务器之间的中间件的物理机或者应用程序。客户端从代理服务器中寻找文件、页面或者是数据，而且代理服务器能处理客户端与服务器之间所有复杂事务，从而满足客户端的生成的需求。 + +代理服务器是WWW（万维网）的支柱，它们其中大部分都是Web代理。一台代理服务器能处理客户端与服务器之间的复杂通信事务。此外，它在网络上提供的是匿名信息（LCTT 译注：指浏览者的 IP、浏览器信息等被隐藏），这就意味着你的身份和浏览痕迹都是安全的。代理可以去配置允许哪些网站的客户能看到，哪些网站被屏蔽了。 + +### 2. Squid是什么? ### + +> **回答** : Squid是一个在GNU/GPL协议下发布的既可作为代理服务器，同时也可作为Web缓存守护进程的应用软件。Squid主要是支持像HTTP和FTP那样的协议，但是对其它的协议比如HTTPS，SSL,TLS等同样也能支持。其特点是Web缓存守护进程通过从经常上访问的网站里缓存Web和DNS数据，从而让上网速度更快。Squid支持所有的主流平台，包括Linux，UNIX，微软公司的Windows和苹果公司的Mac。 + +### 3. Squid的默认端口是什么？怎么去修改它的操作端口？ ### + +> **回答** : Squid运行时的默认端口是3128。我们可以通过编辑它的配置文件来把它的默认端口修改成未被用户使用的端口，路径是 /etc/squid/squid.conf ，建议如下。 + +用你的编辑器打开 ‘/etc/squid/squid.conf’ 文件。 + + # nano /etc/squid/squid.conf + +现在把它修改成未被使用的其它端口，并保存退出。 + + http_port 3128 + +重新启动Squid代理服务，如下显示。 + + # service squid restart + +### 4. 你的公司管理层要求你通过Squid代理服务器屏蔽掉一些域名，你怎么做？ ### + +> **回答** : 屏蔽域名是一个在配置文件中实现的功能模块。我们只需要执行一个小的手动配置即可，建议如下。 + +a. 在 ‘/etc/squid’ 目录下创建一个名为 ‘blacklist’ 的文件。 + + # touch /etc/squid/blacklist + +b. 用nano编辑器打开这个文件。 + + # nano /etc/squid/blacklist + +c. 以每行一个域名的方式将想要屏蔽的域名写进这个文件里。 + + .facebook.com + .twitter.com + .gmail.com + .yahoo.com + ... + +d. 保存退出，然后从 ‘/etc/squid/squid.conf’ 打开Squid配置文件。 + + # nano /etc/squid/squid.conf + +e. 在配置文件中添加如下行。 + + acl BLACKLIST dstdom_regex -i “/etc/squid/blacklist” + http_access deny blacklist + +f. 保存配置文件并退出，重启Squid服务让其生效。 + + # service squid restart + +### 5. 在Squid中什么是媒体范围限制（Media Range Limitation）和部分下载？ ### + +> **回答** : 媒体范围限制是Squid的一种特殊的功能，它只从服务器中获取所需要的数据而不是整个文件。这个功能很好的实现了用户在各种视频流媒体网站如YouTube和Metacafe看视频时，可以点击视频中的进度条来选择进度，因此整个视频不用全部都加载，除了一些需要的部分。 + +Squid部分下载功能的特点是很好地实现了类似在Windows更新时能以一个个小数据包的形式下载，并可以暂停，正因为它的这个特点，正在下载文件的Windows机器可以重新继续下载，而不用担心数据会丢失。Squid的媒体范围限制和部分下载功能只有在存储了一个完整文件的副本之后才行。此外，当用户访问另一个页面时，除非Squid进行了特定的配置，部分下载下来的文件会被删除且不留在缓存中。 + +### 6. 什么是Squid的反向代理？ ### + +> **回答** : 反向代理是Squid的一个功能，这个功能被用来加快最终用户的上网速度。下面用缩写 ‘RS’ 的表示包含了资源的原服务器，而代理服务器则称作 ‘PS’ 。初次访问时，它会从RS得到其提供的数据，并将其副本按照配置好的时间存储在PS上。这样的话每次从PS上请求的数据就相当于就是从原服务器上获取的。这样就会减轻网络拥堵，减少CPU使用率，降低网络资源的利用率，从而缓解原来实际服务器的负载压力。但是RS统计不了总流量的数据，因为PS分担了部分原服务器的任务。‘X-Forwarded-For HTTP’ 信息能用于记录下通过HTTP代理或负载均衡方式连接到RS的客户端最原始的IP地址。 + +从技术上说，用单个Squid服务器同时作为正向代理服务器和反向代理服务器是可行的。 + +### 7. 由于Squid能作为一个Web缓存守护进程，那缓存可以删除吗？怎么删除？ ### + +> **回答** : 当然！作为一个Web缓存守护进程，Squid能加快网页的访问速度，清除缓存也是非常简单的。 + +a. 首先停止Squid代理服务，然后从这个 ‘/var/lib/squid/cache’ 目录中删除缓存。 + + # service squid stop + # rm -rf /var/lib/squid/cache/*< + +b. 创建交换分区目录。 + + # squid -z + +### 8. 你有一台工作中的机器可以访问代理服务器，如果想要限制你的孩子的访问时间，你会怎么去设置那个场景？ ### + +把允许访问的时间设置成晚上4点到7点三个小时，跨度为星期一到星期五。 + +a. 想要限制Web访问时间在星期一到星期五的晚上4点到7点，要先打开Squid的配置文件。 + + # nano /etc/squid/squid.conf + +b. 在配置文件中添加如下行，保存文件并退出。 + + acl ALLOW_TIME time M T W H F 16:00-19:00 + shttp_access allow ALLOW_TIME + +c. 重启Squid服务。 + + # service squid restart + +### 9. Squid存储的数据是什么文件格式？ ### + +> **回答** : Squid存储的数据是UFS文件格式的。UFS是一种老的，使用比较广泛的Squid存储格式 + +### 10. Squid的缓存会存储到哪里？ ### + +> **回答** : Squid存储的缓存是位于 ‘/var/spool/squid’ 的特定目录下。 + +以上就是全部内容了，很快我还会带着其它有趣的内容回到这里。 + +-------------------------------------------------------------------------------- + +via: http://www.tecmint.com/squid-interview-questions/ + +作者：[Avishek Kumar][a] +译者：[ZTinoZ](https://github.com/ZTinoZ) +校对：[wxy](https://github.com/wxy) + +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.tecmint.com/author/avishek/ diff --git a/translated/tech/20140730 How to use variables in shell Scripting.md b/published/20140730 How to use variables in shell Scripting.md similarity index 81% rename from translated/tech/20140730 How to use variables in shell Scripting.md rename to published/20140730 How to use variables in shell Scripting.md index 98768a499f..0e09b5cd5e 100644 --- a/translated/tech/20140730 How to use variables in shell Scripting.md +++ b/published/20140730 How to use variables in shell Scripting.md @@ -13,56 +13,56 @@ shell脚本中的变量是用来**调用**一个**数值**或者**字符值**的 - - + + - + - + - + - + - + - + - + - + - + - + - + - +

While that may be true, Nick Heath today listed "five big names that use Linux on the desktop." He said besides Munich, there's Google for one and they even have their own Ubuntu derivative. He lists a couple of US government agencies and then mentions CERN and others. See that [full story][5] for more. - -Despite that feel-good report, John C. Dvorak said he's tired of waiting for someone to develop that one "killer app" that would bring in the masses or satisfy his needs. [He says][6] he has to make podcasts and "photographic art" and he just can't do that with Linux. Our native applications "do not cut it in the end." - --------------------------------------------------------------------------------- - -via: http://ostatic.com/blog/red-hat-shake-up-desktop-users-and-outta-time - -作者：[Susan Linton][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://ostatic.com/member/susan-linton -[1]:http://www.businesswire.com/news/home/20140827006134/en/Brian-Stevens-Step-CTO-Red-Hat#.U_5AlvFdX0p -[2]:http://www.zdnet.com/red-hat-chief-technology-officer-resigns-7000033058/ -[3]:http://www.infoworld.com/d/data-center/review-rhel-7-lands-jolt-249219 -[4]:http://ostatic.com/blog/linux-doesnt-need-to-own-the-desktop -[5]:http://www.techrepublic.com/article/five-big-names-that-use-linux-on-the-desktop/ -[6]:http://www.pcmag.com/article2/0,2817,2465125,00.asp \ No newline at end of file diff --git a/sources/news/20140901 LibreOffice 4.3.1 Has More than 100 Fixes and DOCX Embedded Objects Support.md b/sources/news/20140901 LibreOffice 4.3.1 Has More than 100 Fixes and DOCX Embedded Objects Support.md deleted file mode 100644 index e592d4c9f3..0000000000 --- a/sources/news/20140901 LibreOffice 4.3.1 Has More than 100 Fixes and DOCX Embedded Objects Support.md +++ /dev/null @@ -1,37 +0,0 @@ -LibreOffice 4.3.1 Has More than 100 Fixes and DOCX Embedded Objects Support -================================================================================ -![LibreOffice selection menu](http://i1-news.softpedia-static.com/images/news2/LibreOffice-4-3-1-Has-More-Than-100-Fixes-and-DOCX-Embedded-Objects-Support-456916-2.jpg) -LibreOffice selection menu - -**The Document Foundation announces that the stable version of LibreOffice 4.3.1 has been released and is now available for download.** - -The developers from The Document Foundation have released a new update for the 4.3 branch of LibreOffice and they have implemented quite a few fixes and other various changes.

Like the traditional client-server model or older mainframe computing,[1] a user connects with a server to perform a task. The difference with cloud computing is that the computing process may run on one or many connected computers at the same time, utilizing the concept of virtualization. With virtualization, one or more physical servers can be configured and partitioned into multiple independent “virtual” servers, all functioning independently and appearing to the user to be a single physical device. Such virtual servers are in essence disassociated from their physical server, and with this added flexibility, they can be moved around and scaled up or down on the fly without affecting the end user. The computing resources have become “granular”, which provides end user and operator benefits including on-demand self-service, broad access across multiple devices, resource pooling, rapid elasticity and service metering capability.[2] - -The above quote was obviously taken from Wikipedia. - -In the past we either used dumb terminals to connect to a mainframe or more recently desktop computers connected to applications on in-house servers which in turn connected to databases also kept on site. - -The management of the desktops, applications and servers were all local and all had to be supported by the company who owned them. - -Whilst this might be great for software houses it isn’t good business for other companies such as banks, insurance companies and oil companies. Information Technology is not a banking function in the same way catering isn’t a function of drilling oil out of the ground. - -Large companies have long since outsourced many functions to dedicated companies. For example outside catering companies provide the staff canteen and we all know about the offshore call centres handling customer calls for the banks. - -IT has also become an offshore function with a number of support and development functions shipped out to China, India, Malaysia and Eastern Europe. - -Cloud computing is different to the typical model in that it is all about virtualisation. It is about putting applications on virtual servers which could all be in one location or could be thousands of miles apart but the point is it doesn’t matter because it is somebody else’s job to make sure they work. - -> In common usage the term “the cloud” has become a shorthand way to refer to cloud computing infrastructure.[4] The term came from the cloud symbol that network engineers used on network diagrams to represent the unknown (to them) segments of a network.[5] Marketers have further popularized the phrase “in the cloud” to refer to software, platforms and infrastructure that are sold “as a service”, i.e. remotely through the Internet. - -This article is therefore all about the cloud and what it means for the everyday linux user and what it can do for you and what, if any, pitfalls are there. - -From an end user and home user point of view, cloud computing has basically come to mean any service that is hosted online. - -So here goes, which cloud services are useful for an everyday linux user? - -### Email ### - -I would be very surprised if you are reading this and you don’t have an email account. - -PC Advisor magazine analysed the top 6 emails services back in March, 2014 consisting of Outlook, GMail, Yahoo, iCloud, AOL and GMX. - -### Office Suites ### - -As well as an email client one of the most commonly used tools required by everyone is an office suite. - -In the past people would toddle off down to PC World, buy a computer and come home with a great big machine and half a dozen CDs containing 5 programs you definitely won’t use and Microsoft Works which was a cheap and virtually useless cut down version of Microsoft Office. - -Now you don’t even need an office suite on your computer even though there are some great free choices out there including LibreOffice and Kingsoft. - -The obvious choices are of course Google Docs and Office 365. Does Office 365 work for Linux? Well this article from PC Pro in 2012 seems to suggest that it does. - -![](http://www.linuxnews.pro/wp-content/uploads/2014/06/office365_1.png) - -I don’t believe everything I read though so I signed up to Office 365 to see what would happen. - -Signing up was free for a month and I was presented with a list of online applications that I could use which included Word, Excel and Outlook. - -![](http://www.linuxnews.pro/wp-content/uploads/2014/06/office365_2.png) - -All looked to be going well. I started Microsoft Word, chose a template to use and then of course it didn’t work at all. - -Office 365 isn’t yet supported on Linux and to be honest you don’t need it. Move on. - -![](http://www.linuxnews.pro/wp-content/uploads/2014/06/office365_3.png) - -Google Docs works and for home use it is perfect. There are hundreds of templates for the word processing and presentation tools and the spreadsheet application does most things although it doesn’t really replace Excel because you haven’t got hundreds of wannabe developers creating naff macros and VBA scripts everywhere. - -![](http://www.linuxnews.pro/wp-content/uploads/2014/06/zoho_1.png) - -Another alternative to Office 365 is Zoho. - -Similar to Google Docs, Zoho includes a word processor, spreadsheet tool, presentation tool and mail. - -There are finance and CRM tools as well. - -![](http://www.linuxnews.pro/wp-content/uploads/2014/06/zoho_2.png) - -The interface for the tools is actually very nice and clean. - -Services such as Google Docs and Zoho also give you the power of collaboration. - -Documents can be shared and worked on by different people in different locations. - -This site provides a good list of alternative choices to Google Docs and Zoho. - -### Online File Storage ### - -Another good service provided by Google Docs and Zoho is the ability to store the documents and files you create online. - -There are other services however such as Dropbox that are used to exclusively store your documents in the cloud. - -The benefit of storing files with services like Dropbox is that if your house is burgled or catches fire then you have an offshore backup that remains intact. You can also access your files anywhere. - -Dropbox is free for up to 2 gigabytes of use. If you have a lot more data, and most of us do nowadays, then there is a $ 9.99 monthly plan that is available allowing for 100 gigabytes. There is also a business version available from $ 15 a month. - -There are of course alternatives to Dropbox and this site provides a list of the best online backup solutions. - -### Photos ### - -Since the introduction of digital cameras and more recently smart phones, more and more of us have memory cards full of photos. - -I bet that at some point or other that you have lost photos because your phone died and the photos were on the phone and not the memory card or you lost your phone losing pictures of your child’s sports day or another important occasion. - -Losing a phone is never a good thing. If you are clever you will have set up some sort of security because most people have their phones synchronised with their email accounts, Facebook, Twitter and even online banking. - -All it takes to fix a lost phone is to change the passwords to all of the above accounts but lost photos are just not possible to recover and are a little bit more upsetting when lost. - -One solution of course is to backup to your computer. This is of course a good first step but occasionally laptops break as well and you are back to square one. - -Online photo storage sites are great resources because not only do they keep your photos safe you can also share them with whoever you choose to, eliminating the need to get 5 copies of the same photo developed to send to mum, nan, sister, aunty and mother-in-law. - -The solution I like to use is Google’s Picasa but many of you will have heard of services like Flickr as well. - -Lifehacker has a list of the five best photo sharing services. - -Remember though that just because they are called photo sharing services doesn’t mean you have to share them. You can keep them just to yourself. - -### Music ### - -The first record that I was ever given was a 12 inch vinyl version of “Kings of the wild frontier” by “Adam and the Ants” back in the early 1980s. - -As the 1980s progressed the long play records were replaced by cassettes and just as I had accumulated a decent number of cassettes the compact disc became the thing to have. - -Hundreds of compact discs later and MP3 file sharing became the norm and it even became the legal way of doing things. - -Nothing sits still with technology and the future is now with audio streaming services such as Spotify. - -Spotify is free to use but is supported with the inclusion of adverts. In this regard it is like having your own personal radio station where you choose the playlist. Of course you can pay a monthly fee and have the adverts removed altogether. - -There are dozens of similar services including Grooveshark and last.fm. - -Techradar has a list of 7 alternatives to Spotify. - -### Film ### - -The first film I ever watched in the Cinema was Dumbo. The first video I ever watched was “Krull” which contained a young Dulph Lundgren. The format of the video was on Beta Max. (My next door neighbour had one). - -My dad came home one day with a video recorder from Radio Rentals and my sister and I used to take it in turns to pick a video to hire from the video store. I remember my first choice being “The Black Hole”. - -As with music time moves on. Just as you get large units full of movies, some genius comes along and develops DVDs and then they come out with Bluerays. - -Now of course video streaming is the order of the day especially if you have a decent enough internet connection. - -The most commonly known services are Netflix and Lovefilm. - -This website has a list of good alternatives to Netflix. Not all of these services (including Netflix) work seamlessly on Linux. - -### Gaming ### - -Music, films and now gaming have moved to the online arena. - -Gaming is of course more difficult.

If someone gets access to your online banking or your email then you have a real problem. - -What about online file storage? There is currently the high profile case of Megaupload.com. - -Megaupload.com was essentially a file storage site for storing large files. The problem is that a lot of people used the service to share copyright material and the US authorities came down like a ton of bricks and the service was shut down. - -Now a lot of people losing files would perhaps be expecting the inevitable but what about people who genuinely did nothing wrong. Their data has been lost. The US authorities refusing to give it back. - -Finally there is the subject of service maintenance. If your email went down for a day could you cope? What about 3 days? What about a month? You are at the mercy of the service provider. - -A lot has been made about large companies losing data and there has also been a lot of noise regarding heartbleed which is a vulnerability found in SSL left unpatched for years. - -If you have services hosted for you online then you are relying on technical support staff to do their job properly and if they don’t you could be at the mercy of hackers, hardware failures and poor backup and recovery maintenance. - -### Summary ### - -Cloud computing has really become the buzz term for any online service. Your web browser is a client connecting to a server or clusters of servers hosted anywhere in the world. The point is that you don’t care. You don’t need to know. - -Generally speaking I have barely touched the surface. We all use the cloud everyday and most of us don’t even think about it. - -How does the cloud affect the everyday linux user? It turns out quite a bit. - -Is the cloud a good or bad thing? Neither. Each service has to be judged on it’s own merits. - -The term “The Cloud” is just something marketing people and the technical press get excited about.

His logic is sound and simple: disruptive technologies like the cloud that arise every couple decades level the playing field between large, established firms and smaller, innovative challengers since everyone, from corporate behemoth to a couple guys in a garage, starts from the same spot and must play by the same unfamiliar and changeable rules. With the cloud “there’s less of an installed based and an opportunity for new winners to be chosen,” Whitehurst adds. His mission is “to see that open source is the default choice for next generation architecture” and that Red Hat is the preferred choice, particularly for enterprise IT, of open source providers. - -The case for open source dominating the cloud rests on the fact that it’s already the foundation for many popular cloud services and enterprise applications. Whitehurst aptly notes that outside of Microsoft Azure, the underlying infrastructure of all the major public cloud services is built upon open source software. Furthermore, software like Linux, Apache, MySQL, WordPress and many others are already widely used and trusted by most enterprises. “In many cases [open source] already is the default choice for next generation architectures, but it hasn’t fully driven itself through the traditional enterprise data center,” he says. Cloud software is the next and most important software category up for open source disruption. - -![](http://blogs-images.forbes.com/kurtmarko/files/2014/06/redhat-logo.jpg) - -Yet open source is still saddled with a reputation for widely variable software quality and support, something the recent OpenSSL Heartbleed bug only reinforced. However Whitehurst contends that strong enterprise adoption of Red Hat’s Linux distribution and it’s training and skills certification programs lends credibility to a similar plan for the cloud: [Red Hat’s Cloud Partner Program][1]. He believes such insurance policies alleviate enterprise IT’s fears of adopting open source software for both internal, private clouds and external public cloud services. Red Hat wants its imprimatur to be the Good Housekeeping seal of approval for open source in general and cloud software in specific, namely IT’s assurance that their applications will work and the service is trustworthy and reliable. - -Red Hat’s strategy to make open source clouds safe for the enterprise is mirrors that used to break into the market for enterprise server software. There, “Job one for Red Hat is making sure our operating system and layers above that work well on anyone’s infrastructure underneath,” says Whitehurst. Red Hat is applying this same model of polishing, integrating and supporting open source software to cloud stacks. “One of the most important parts about cloud, public, private or hybrid, is a sense that you can confidently run your applications,” says Whitehurst and he believes Red Hat’s track record on Linux and other open source products will carry over to make Red Hat “the enterprise choice” for cloud architectures. - -### Cloud isn’t just virtualization 2.0 ### - -One of the conundrums for OpenStack advocates like Whitehurst is the entrenchment of Microsoft and VMware in the enterprise market. Although virtual servers are a prerequisite for clouds, they’re sufficient. Countering the notion that enterprise clouds are just a natural extension of virtualized servers and storage, Whitehurst argues that by setting new rules for infrastructure and application design, cloud infrastructure is more than just the natural evolution of server virtualization. - -![](http://blogs-images.forbes.com/kurtmarko/files/2014/06/RH_NEXT_HS-JIM-W-01.jpg) - -Whitehurst draws an important distinction between traditional client-server and cloud-optimized applications. “One of the big questions will be how much of this [cloud adoption] is moving traditional Windows workloads, which frankly were written as stateful apps in the first place. [Instead] are we talking about a new generation of applications that are actually built with elasticity and scalability in mind.” Whitehurst clearly believes cloud infrastructure is much more appropriate for the latter and that in such Greenfield scenarios, OpenStack and other open source software have established themselves as the preferred platform. Contrasting OpenStack, based on the Linux KVM hypervisor and VMware or Microsoft using their proprietary virtual machine platforms, Whitehurst says, “Longer term, nobody really cares what the hypervisor is, you just expect it to work and bluntly, as long as Red Hat supports you on it, why do you have to care,” adding “more and more, you’ll see the hypervisor mattering less and less.” Of course, VMware and Microsoft probably agree, both having moved their energies to building more sophisticated management platforms and making the hypervisor a baseline feature. - -But in Whitehurst’s view of the world, traditional virtualization platforms like VMware or Microsoft Hyper-V are legacy infrastructure designed for yesterday’s client-server software, not the sort of distributed, rapidly relocatable, elastically scalable applications that define the era of big data, SaaS and social software. “I’m not sure what good you get out of putting Exchange on a cloud,” he quips. Instead, he says this new generation of cloud-optimized applications are the sweet spot for OpenStack. According to Whitehurst, “If you look at where most new applications are getting built, and therefore where so much of the innovation around languages, frameworks and management paradigms are happening, it’s around an open infrastructure.” But there’s obviously some selection bias in Whitehurst’s account, as he lives in an open source world where it’s easy to be unaware, overlook or ignore the innovation happening on proprietary cloud platforms like Azure, AWS and vCloud. - -In sum, Whitehurst hopes and expects OpenStack to do to VMware what Linux did to Windows: to become the first choice of cloud-savvy startups and if not the default choice, at least an accepted and respectable alternative within the enterprise. In my next column I’ll explain that even for an open source champion like Whitehurst, OpenStack versus VMware vCloud or Microsoft Azure isn’t an either/or choice and how he sees the fundamental notion of cloud computing as based on virtual machines as an design model likely to change. - --------------------------------------------------------------------------------- - -via: http://www.forbes.com/sites/kurtmarko/2014/06/08/red-hat-ceo-open-source-clouds/ - -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://www.redhat.com/partners/become/cloud/ \ No newline at end of file diff --git a/sources/talk/20140612 Linux hiring frenzy--Why open source devs are being bombarded with offers to jump ship.md b/sources/talk/20140612 Linux hiring frenzy--Why open source devs are being bombarded with offers to jump ship.md deleted file mode 100644 index 4115b21b64..0000000000 --- a/sources/talk/20140612 Linux hiring frenzy--Why open source devs are being bombarded with offers to jump ship.md +++ /dev/null @@ -1,27 +0,0 @@ -Linux hiring frenzy: Why open source devs are being bombarded with offers to jump ship -================================================================================ -> Summary: Figures from the Linux Foundation suggest skills shortages across disciplines and throughout Europe. - -Nine out of ten (87 percent) of hiring managers in Europe have "hiring Linux talent" on their list of priorities and almost half (48 percent) say they are looking to hire people with Linux skills within the next six months. - -But while they either need or want to hire more people with Linux skills, the data from the Linux Foundation suggests that this is easier said than done.

Hundreds of thousands of customers look to Rackspace to deliver the best-fit hybrid cloud solutions for their IT needs, leveraging a product and services portfolio that allows workloads to run where they perform best – whether on the public cloud, private cloud, dedicated servers, or a combination of platforms. - -As a managed cloud pioneer, we give our customers 24x7 access to cloud engineers for everything from planning and architecting to building and operating clouds through our award-winning Fanatical Support®. We help customers successfully architect, deploy and run their most critical applications. Or, more plainly put, we’re cloud specialists so you don’t have to be. We are headquartered in San Antonio, Texas, and operate a global support and engineering organization with data centers on four continents. - -### How and why do you use Linux? ### - -Rackspace uses Linux because it provides a stable and flexible platform for our customers' workloads. Our customers trust us to support their mission-critical applications and we need reliable infrastructure – including software and hardware – to meet their expectations. If you look under the hood in our dedicated environments or in our expansive cloud infrastructure, you'll find Linux running there. - -Many of the applications and infrastructure that we need to run for internal use or for customers run best on Linux. This includes all the popular language frameworks and open virtualization platforms such as Xen, LXC, KVM, Docker, etc. Running combinations of these platforms give us the stability and performance we demand for the Rackspace Cloud. Our Cloud Servers product runs OpenStack services that manage tens of thousands of hypervisors – all running Linux. - -Using Linux also allows us to tap into a community of experts to solve problems. When we have an issue, we're comfortable asking questions. When we have a solution, we enjoy sharing it with the community. At Rackspace, we understand how to work and contribute in an open community and Linux has many opportunities to build relationships with other groups that have similar goals. - -### Why did you join the Linux Foundation? ### - -Joining the Linux Foundation allows us to show our support and engage the Linux community in new ways. We've learned plenty from running Linux in highly demanding environments at a large scale and we're eager to share those experiences. Other members of the community have probably run into different challenges than we have and this gives us a greater opportunity to learn from them as well. - -### What interesting or innovative trends are you witnessing in the data center and what role does Linux play in them? ### - -Virtualization and automation have changed how companies deploy hardware and software. Linux gives us several virtualization options and these allow us to automate more of our infrastructure deployments and maintenance tasks. Automation and configuration management frameworks allow us to reduce our costs, improve our testing capabilities, and bring products to market faster. The majority of these open source automation frameworks run best on Linux servers. - -### How is Rackspace participating in that innovation? ### - -We leverage several open-source Linux-based tools and projects to deliver great customer outcomes. One of our largest efforts in this area is with OpenStack. It's the software that runs our public and private clouds and we're actively engaged with the community to improve it. We're using Linux to find new ways to scale our large virtualization platform and deliver infrastructure to customers quickly. - -The open-source nature of Linux inspires us to share the majority of these discoveries with the community. Our customers can improve OpenStack and those improvements will eventually make it into our product offering. We make contributions to a countless number of open source projects either as a company or as individual Rackers (our employees are called "Rackers") and many of these projects are designed to run on Linux. - -### What other future technologies or industries do you think Linux and open source will increasingly become important in and why? ### - -The move to software-defined infrastructure is a big shift. Customers already have access to virtualization platforms like Xen that allow them to define their infrastructure with software. Software-defined networking is quickly becoming more mature and scalable. However, customers want the ability to have a software defined datacenter at their fingertips. This may involve physical servers, virtual servers, and virtual networks that need high performance with flexible configurations. Many of the current technologies are designed to run on Linux due to technology already available in the kernel or userland frameworks provided by the community. - -### Are you hiring? ### - -From hacking on kernels to supporting thousands of virtual machines – we are always looking for talented admins, developers and engineers.

GCC is huge and venerable: 5 million lines, 30 years, and growing. LLVM, in contrast, is relatively youthful and modular and allows free and proprietary languages to be added as modules. - -The core of LLVM is ‘open source’. GCC is copyleft and unreservedly free software and doesn’t allow plug-ins or other means to add proprietary extensions to the GCC code. The argument, as delivered by Eric Raymond, is that “FSF can no longer prevent proprietary vendors from plugging into a free compiler to improve their tools. That horse has left the barn; the strategic goal of the anti-plug-in policy has been definitively busted.” - -LLVM has been sponsored by Apple as a replacement for GCC on OS X and Apple hardware and has grown in popularity, especially among users of the BSDs. Advocates of LLVM see it as a putative replacement for GCC in the wider market for applications developers and mobile devices. The argument against GCC is that its complexity, and the commitment of its developers to copyleft licensing, constrains the possibilities for proprietary developers, who do not want to release their language or architectural specifications under a copyleft licence. Apple, of course, has a long history of antipathy to free software, and doesn’t allow applications licensed under copyleft licences to be distributed through its App Store. - -To this extent, the argument between LLVM and GCC is a retread of the historic differences between GNU/Linux and the BSDs, between ‘open source’ and free software. Open source developers allow the code to be reused in any context, free or proprietary. Free software is restrictive in that it insists that the code, and any modifications to the code, must remain free in perpetuity. Advocates of free software would argue that the integrity of copyleft licensing has been instrumental in the spread of GCC, and has taken Linux and free software into places it would not otherwise have reached, and that free software cannot be bought or corrupted by commercial or corporate interests. Open source advocates argue that open source is more free because the user has no restrictions and can do what he or she likes, including developing closed source versions of the code. - -Since the beginning, the GNU Compiler Collection (GCC) was vital to the spread of free software. Compilers were a rare and expensive commodity and the compilers of the proprietary software companies were rife with ‘features’ that were non-compliant with ANSI programming standards. Porting software between different machines and operating systems was an unnecessarily complicated task. GCC, the first truly free cross-platform compiler, commoditised this process. - -GCC was a breakthrough product for applications developers and mobile device developers – not just those who were committed to the idea of free software. Not only was GCC free and portable, its ubiquity and commonality across different architectures made it easier to port software between machines and to expect robust and consistent results – as the likes of John Gilmore, Michael Tiemann and David Henkel- Wallace were to discover when they made GCC and its development the key selling point of Cygnus Solutions, the first company to make money by selling free software. - -The primary technical difference between LLVM and GCC emerges in the separation between the modules that form the ‘front ends’, ‘middle end’ and ‘back ends’ of both GCC and LLVM. ‘Front ends’ are used to interpret the code specific to the translation of a particular language. The ‘middle end’ optimises the translated code. The ‘back ends’ take the optimised code and apply the results to a specific target architecture. LLVM separates these modules into distinct entities, but for semantic and historical reasons, GCC obfuscates the separation between the modules. - -Perhaps untypically for a free software project, it is a difficult process to add a new language or architecture to GCC and the adding of proprietary plug-ins is not allowed. There is little clear separation between the modules, and the path of least resistance is to add any feature under a free software licence. The early ports of C++ and Objective C (via Apple) are cited as examples where the original developers might have preferred to keep the code in-house and proprietary, and instead released the code as free software. - -In contrast, LLVM has allowed, or perhaps even encouraged, the addition and development of proprietary languages and architectures – one example being Nvidia’s NVCC for GPU computing, based on Clang and LLVM. The source code of NVCC is inaccessible to free software or ‘open source’ developers. - -Richard Stallman’s [take on this][1] is characteristically resolute: “In the free software movement, we campaign for the freedom of the users of computing. The values of free software are fundamentally different from the values of open source, which make‘bettercode’theultimategoal. IfGCCwere to change from a free compiler into a platform for non-free compilers, it would no longer serve the goal of freedom very well. - -“The Clang and LLVM developers reach different conclusions from ours because they do not share our values and goals. They object to the measures we have taken to defend freedom because they see the inconvenience of them and do not recognise (or don’t care about) the need for them. I would guess they describe their work as ‘open source’ and do not talk about freedom.” - -The GCC developers are unlikely to compromise on the licensing terms. While LLVM is fashionable among certain sectors of industry, because it is young and new and has been quicker to jump on developing trands in programming languages, the prevailing wind is towards greater openness, and GCC’s resolve to be incorruptible and free from commercial interests, may be the greater asset in the long term. The Unix companies learnt something from the Unix wars of the Eighties and Nineties. Languages and operating systems are tools, and are better open and shared. GCC is free software and belongs to nobody. - --------------------------------------------------------------------------------- - -via: http://www.linuxuser.co.uk/features/staying-free-should-gcc-allow-non-free-plug-ins - -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://lwn.net/articles/582241 \ No newline at end of file diff --git a/sources/talk/20140801 $2400 Valued Introduction To Linux Course Is Available For Free On edX.md b/sources/talk/20140801 $2400 Valued Introduction To Linux Course Is Available For Free On edX.md deleted file mode 100644 index 3eafcb4fe0..0000000000 --- a/sources/talk/20140801 $2400 Valued Introduction To Linux Course Is Available For Free On edX.md +++ /dev/null @@ -1,37 +0,0 @@ -$2400 Valued Introduction To Linux Course Is Available For Free On edX -================================================================================ -![](http://itsfoss.itsfoss.netdna-cdn.com/wp-content/uploads/2014/07/Introduction_Linux_edX.jpg) - -Probably you have already heard it.

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? Are you also playing them now in your favourite Linux distro?

Great! Just configure** Terminal or Command Prompt, learn to use it and then install all the languages, add-on libraries and APIs you’ll need. When you're finally through with all that, you can get started with installing [Visual Studio][1] so you can preview your work. - -At least that's how you used to have to do it. - -No wonder beginning coders are increasingly turning to online integrated development environments (IDEs). An IDE is a code editor that comes ready to work with languages and all their dependencies, saving you the hassle of installing them on your computer. - -I wanted to learn more about what constitutes the typical IDE, so I took a look at the free tier for three of the most popular integrated development environments out there: [Cloud9][2], [Koding][3], and [Nitrous.IO][4]. In the process, I learned a lot about the cases in which programmers would and would not want to use IDEs. - -### Why Use An IDE? ### - -If a text editor is like Microsoft Word, think of an IDE as Google Drive. You get similar functionality, but it's accessible from any computer and ready to share. As the Internet becomes an increasingly influential part of project workflow, IDEs make life easier. - -I used Nitrous.IO for my last ReadWrite tutorial, the Python app in [Create Your Own Obnoxiously Simple Messaging App Just Like Yo][5]. When you use an IDE, you select the language you want to work in so you can test and preview how it looks on the IDE’s Virtual Machine (VM) designed to run programs written specifically in that language. - -If you read the tutorial, you'll see there are only two API libraries that my app depended on—messaging service Twilio and Python microframework Flask. That would have been easy to build using a text editor and Terminal on my computer, but I chose an IDE for yet another convenience: when everyone is using the same developer environment, it’s easier to follow along with a tutorial. - -### What An IDE Is Not ### - -Still, an IDE is not a long term hosting solution. - -When you’re working on an IDE, you’re able to build, test and preview your app in the cloud. You’re even able to share the final draft via link. - -But you can’t use an IDE to store your project permanently. You wouldn't ditch your blog in favor of hosting your posts as Google Drive documents. Like Google Drive, IDEs allow you to link and share content, but neither are equipped to replace real hosting. - -What's more, IDEs aren't designed for wide-spread sharing. Despite the increased functionality IDEs add to the preview capability of most text editors, stick with showing off your app preview to friends and coworkers, not with, say, the front page of Hacker News. In that case, your IDE would probably shut you down for excessive traffic. - -Think of it this way: an IDE is a place to build and test your app; a host is a place for it to live. So once you’ve finalized your app, you’ll want to deploy it on a cloud-based service that lets you host apps long term, preferably one with a free hosting option like [Heroku][6]. - -### Choosing An IDE ### - -![](http://a2.files.readwrite.com/image/upload/c_fit,w_630/MTIzNjEzMTg5MjA2NDc2MzAy.png) - -As IDEs become more popular, more are popping up all the time.

Here's what I found. - -### Cloud9: Ready To Collaborate ### - -When I signed up for Cloud9, one of the first things it prompted me to do was integrate my GitHub and BitBucket accounts.

Other IDEs have nowhere near this level of GitHub integration. - -Out of the three IDEs I looked at, Cloud9 seemed most intent on ensuring an environment where I could work seamlessly with co-coders. Here, it’s not just a chat function in the corner. In fact, said CEO Ruben Daniels, Cloud9 collaborators can see each others coding in real time, just like co-authors are able to on Google Drive. - -“Most services’ collaborative features only work on a single file,” said Daniels. “Ours work on multiples throughout the project. Collaboration is fully integrated within the IDE.” - -### Koding: Help When You Need It ### - -IDEs give you the tools you need to build and test applications in the gamut of open source languages. For a beginner, that can be a little bit intimidating. For example, if I’m working on a project with both Python and Ruby components, which VM do I use for testing? - -The answer is both, though on a free account, you can only turn on one VM for testing at a time. I was able to find that out right on my Koding dashboard, which doubles as a place for users to give and get advice on their Koding projects. Of the three, it’s the most transparent when it comes to where you can ask for assistance and hear back in minutes. - -“We have an active community built into the application,” said Nitin Gupta, Chief Business Officer at Koding. “We wanted to create an environment that is extremely attractive to people who need help and who want to help.” - -### Nitrous.IO: An IDE Wherever You Want ### - -The ultimate advantage of using an IDE over your own desktop environment is that it’s self-contained. You don’t have to install anything to use it. On the other hand, the ultimate advantage of using your own desktop environment is that you can work locally, even without Internet. - -Nitrous.IO gives you the best of both worlds. You can use the IDE on the Web, or you can download it to your own computer, said cofounder AJ Solimine. The advantage is that you can merge the integrations of Nitrous with the familiarity of your preferred text editor. - -“You can access Nitrous.IO from any modern web browser via our online Web IDE, but we also have handy desktop applications for Windows and Mac that let you edit with your favorite editor,” he said. - -### The Bottom Line ### - -The most surprising thing I learned from a week of [using][7] three different IDEs? How similar they are. [When it comes to the basics of coding][8], they’re all equally helpful. - -Cloud9, Koding, [and Nitrous.IO all support][9] every major open source language, from Ruby to Python to PHP to HTML5. You can choose from any of those VMs. - -Both Cloud9 and Nitrous.IO have built-in one-click GitHub integration. For Koding there are a [couple more steps][10], but it can be done. - -Each integrated easily with the APIs I needed. Each let me install my preferred package installers, too (and Koding made me do it as a superuser). They all have a built in Terminal for easily testing and deploying projects. All three allow you to easily preview your project. And of course, they all hosted my project in the cloud so I could work on it anywhere. - -On the downside, they all had the same negatives, which is reasonable when you consider they're free. You can only run one VM at a time to test a program written in a particular language. When you’re not using your VM for a while, the IDE preserves bandwidth by putting it into hibernation and you have to wait for it to reload next time you use it (and Cloud9 was especially laborious). None of them make a good permanent host for your finished projects. - -So to answer those who ask me if there’s a perfect free IDE out there, probably not. But depending on your priorities, there might be one that’s perfect for your project. - -Lead image courtesy of [Shutterstock][11] - --------------------------------------------------------------------------------- - -via: http://readwrite.com/2014/08/14/cloud9-koding-nitrousio-integrated-development-environment-ide-coding - -作者：[Lauren Orsini][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://readwrite.com/author/lauren-orsini -[1]:http://www.visualstudio.com/ -[2]:http://c9.io/ -[3]:https://koding.com/ -[4]:http://nitrous.io/ -[5]:http://readwrite.com/2014/07/11/one-click-messaging-app -[6]:http://heroku.com/ -[7]:http://help.nitrous.io/ide-general/ -[8]:https://www.nitrous.io/desktop -[9]:https://www.nitrous.io/desktop -[10]:https://koding.com/Activity/steps-clone-projects-github-koding-1-create-account-github-2-open-your-terminal-3 -[11]:http://www.shutterstock.com/ diff --git a/sources/talk/20140818 Why Your Company Needs To Write More Open Source Software.md b/sources/talk/20140818 Why Your Company Needs To Write More Open Source Software.md deleted file mode 100644 index 04aa33c138..0000000000 --- a/sources/talk/20140818 Why Your Company Needs To Write More Open Source Software.md +++ /dev/null @@ -1,68 +0,0 @@ -Why Your Company Needs To Write More Open Source Software - ReadWrite -================================================================================ -> Real innovation doesn't happen behind closed doors. - -![](http://a5.files.readwrite.com/image/upload/c_fill,h_900,q_70,w_1600/MTE5NDg0MDYxMTkxMzQxNTgz.jpg) - -**The Wall Street Journal [thinks][1] it's news that Zulily is developing** "more software in-house." It's not. At all. As [Eric Raymond wrote][2] years ago, 95% of the world's software is written for use, not for sale. The reasons are many, but one stands out: as Zulily CIO Luke Friang declares, it's "nearly impossible for a [off the shelf] solution to keep up with our pace." - -True now, just as it was true 20 years ago. - -But one thing is different, and it's something the WSJ completely missed. Historically software developed in-house was zealously kept proprietary because, the reasoning went, it was the source of a firm's competitive advantage. Today, however, companies increasingly realize the opposite: there is far more to be gained by open sourcing in-house software than keeping it closed. - -Which is why your company needs to contribute more open-source code. Much more. - -We've gone through an anomalous time these past 20 years. While most software continued to be written for internal use, most of the attention has been focused on vendors like SAP and Microsoft that build solutions that apply to a wide range of companies. - -That's the theory, anyway. - -In practice, buyers spent a small fortune on license fees, then a 5X multiple on top of that to make the software fit their requirements. For example, a company may spend $100,000 on an ERP system, but they're going to spend another $500,000 making it work. - -One of the reasons open source took off, even in applications, was that companies could get a less functional product for free (or a relatively inexpensive fee) and then spend their implementation dollars tuning it to their needs. Either way, customization was necessary, but the open source approach was less costly and arguably more likely to result in a more tailored result. - -Meanwhile, technology vendors doubled-down on "sameness," as Redmonk analyst [Stephen O'Grady describes][3]: - -> The mainstream technology industry has, in recent years, eschewed specialization. Virtual appliances, each running a version of the operating system customized for an application or purpose, have entirely failed to dent the sales of general purpose alternatives such as RHEL or Windows. For better than twenty years, the answer to any application data persistence requirement has meant one thing: a relational database. If you were talking about enterprise application development, you were talking about Java. And so on. - -Along the way, however, companies discovered that vendors weren't really meeting their needs, even for well-understood product categories like Content Management Systems. They needed different, not same. - -So the customers went rogue. They became vendors. Sort of. - -As is often the case, [O'Grady nails][4] this point. Writing in 2010, O'Grady uncovers an interesting trend: "Software vendors are facing a powerful new market competitor: their customers." - -Think about the most visible technologies today. Most are open source, and nearly all of them were originally written for some company's internal use, or some developer's hobby. Linux, Git, Hadoop, Cassandra, MongoDB, Android, etc. None of these technologies were originally written to be sold as products. - -Instead, they were developed by companies—usually Web companies—building software to "[scratch their own itches][5]," to use the open source phrase. And unlike previous generations of in-house software developed at banks, hospitals and other organizations, they open sourced the code. - -While [some companies eschew developing custom software][6] because they don't want to maintain it, open source (somewhat) mitigates this by letting a community grow up to extend and maintain a project, thereby amortizing the costs of development for the code originators. Yahoo! started Hadoop, but its biggest contributors today are Cloudera and Hortonworks. Facebook kickstarted Cassandra, but DataStax primarily maintains it today. And so on. - -Today real software innovation doesn't happen behind closed doors. Or, if it does, it doesn't stay there. It's open source, and it's upending decades of established software orthodoxy. - -Not that it's for the faint of heart. - -The best open-source projects [innovate very fast][7]. Which is not the same as saying anyone will care about your open-source code. There are [significant pros and cons to open sourcing your code][8]. But one massive "pro" is that the best developers want to work on open code: if you need to hire quality developers, you need to give them an open source outlet for their work. (Just [ask Netflix][9].) - -But that's no excuse to sit on the sidelines. It's time to get involved, and not for the good of some ill-defined "community." No, the primary beneficiary of open-source software development is you and your company. Better get started. - -Lead image courtesy of Shutterstock. - --------------------------------------------------------------------------------- - -via: http://readwrite.com/2014/08/16/open-source-software-business-zulily-erp-wall-street-journal - -作者：[Matt Asay][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://readwrite.com/author/matt-asay -[1]:http://blogs.wsj.com/cio/2014/08/08/zulily-calls-in-house-software-a-differentiator-for-competitive-advantage/ -[2]:http://oreilly.com/catalog/cathbazpaper/chapter/ch05.html -[3]:http://redmonk.com/sogrady/2010/01/12/roll-your-own/#ixzz3ATBuZsef -[4]:http://redmonk.com/sogrady/2010/01/12/roll-your-own/ -[5]:http://en.wikipedia.org/wiki/The_Cathedral_and_the_Bazaar -[6]:http://www.abajournal.com/magazine/article/roll_your_own_software_hidden_dangers_on_the_road_less_traveled/ -[7]:http://readwrite.com/2013/12/12/open-source-innovation -[8]:http://readwrite.com/2014/07/07/open-source-software-pros-cons -[9]:http://techblog.netflix.com/2012/07/open-source-at-netflix-by-ruslan.html \ No newline at end of file diff --git a/sources/talk/20140826 Linus Torvalds Promotes Linux for Desktops, Embedded Computing.md b/sources/talk/20140826 Linus Torvalds Promotes Linux for Desktops, Embedded Computing.md deleted file mode 100644 index 0d6322820b..0000000000 --- a/sources/talk/20140826 Linus Torvalds Promotes Linux for Desktops, Embedded Computing.md +++ /dev/null @@ -1,31 +0,0 @@ -Linus Torvalds Promotes Linux for Desktops, Embedded Computing -================================================================================ -> Linux kernel developer and open source leader Linus Torvalds spoke recently about the future of desktop Linux and Linux for embedded devices. - -![](http://thevarguy.com/site-files/thevarguy.com/files/imagecache/medium_img/uploads/2014/08/linus-torvalds-1.jpg) - -What's the future of Linux for desktop computers and embedded devices? That's a question up for debate, but Linux founder and open source superstar Linus Torvalds provided some intriguing viewpoints in a discussion at the [Linux Foundation's][1] recent LinuxCon event. - -As the guy who wrote the first Linux kernel code and shared it publicly over the Internet back in 1991, Torvalds is without doubt among the most famous developers of open source software—or any software, really—alive today. And while Torvalds is only one individual among many thousands of people and organizations guiding the development of Linux, his opinions tend to be influential with the open source community, and his role as a lead kernel developer places him in a powerful position for deciding which features and code make it into the operating system. - -So it's worth paying attention when Torvalds says, "I still want the desktop," as he [did last week][2] at LinuxCon. It's a sign that he still sees a future for Linux as an operating system for powering personal PCs, even though desktop Linux market share has remained minuscule and relatively flat for more than a decade, and most of the commercial activity around Linux these days involves servers or Android-powered mobile hardware. - -But, Torvalds added, ensuring a strong future for desktop Linux means solving an "infrastructure problem" that stems, he seems to believe, from the broader open source software ecosystem and the hardware world. It's not the core Linux code itself that's at issue, and making the channel friendly for desktop Linux is a feat Torvalds and his fellow kernel developers probably have little power to achieve on their own. That's up to app developers, hardware manufacturers and other parties who have the power to deliver computing platforms based on Linux that people will readily use. - -On the other hand, Torvalds also mentioned a hope that kernel developers might streamline the Linux code for embedded devices—a task that might be at odds in some ways with making the kernel more desktop-friendly. But that's not necessarily the case, and at any rate, given that Linux is designed to be so modular, there's no reason a single kernel code base can't meet the needs of desktop users and embedded developers equally well, depending on which chunks they choose to use. - -As a longtime desktop Linux user who would also like to see more Linux-powered embedded devices, I'm hoping Torvalds's aspirations in both regards will be realized, and that I will one day be able to do everything I need using only Linux, whether it's on a desktop computer, a mobile phone, the car or anywhere else. - --------------------------------------------------------------------------------- - -via: http://thevarguy.com/open-source-application-software-companies/082514/linus-torvalds-promotes-linux-desktops-and-embedded-compu - -作者：[Christopher Tozzi][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://thevarguy.com/author/christopher-tozzi -[1]:http://linuxfoundation.org/ -[2]:http://www.eweek.com/enterprise-apps/linux-founder-linus-torvalds-still-wants-the-desktop.html \ No newline at end of file diff --git a/sources/talk/20140828 Interesting facts about Linux.md b/sources/talk/20140828 Interesting facts about Linux.md deleted file mode 100644 index d257f4f2fe..0000000000 --- a/sources/talk/20140828 Interesting facts about Linux.md +++ /dev/null @@ -1,85 +0,0 @@ -Interesting facts about Linux -================================================================================ -Today, August, 25th, is the 23rd birthday of Linux.

If there is anything to add, feel free to share it in the comments. In this article, I will use the terms "Linux", "kernel" or "Linux kernel" interchangeably to mean the same thing. - -1. There is a never-ending debate on whether or not Linux is an operating system. Technically, the term "Linux" refers to the kernel, a core component of an operating system. Folks who argue that Linux is not an operating system are operating system purists who think that the kernel alone does not make the whole operating system, or free software ideologists who believe that the largest free operating system should be named "[GNU/Linux][7]" to give credit where credit is due (i.e., [GNU project][8]). On the other hand, some developers and programmers have a view that Linux qualifies as an operating system in a sense that it implements the [POSIX standard][9]. - -2. According to openhub.net, the majority (95%) of Linux is written in C language. The second popular language for Linux is assembly language (2.8%). The dominance of C lanaguage over C++ is no surprise given Linus's stance on C++. Here is the programming language breakdown for Linux. - -![](https://farm4.staticflickr.com/3845/15025332121_055cfe3a2c_z.jpg) - -3. Linux has been built by a total of [13,036 contributors][10] worldwide. The most prolific contributor is, of course, Linus Torvalds himself, who has committed code more than 20,000 times over the course of the lifetime of Linux. The following figures show the all-time top-10 contributors of Linux in terms of commit counts. - -![](https://farm4.staticflickr.com/3837/14841786838_7a50625f9d_b.jpg) - -4. The total source lines of code (SLOC) of Linux is over 17 million. The estimated cost for the entire code base is 5,526 person-years, or over 300M USD according to [basic COCOMO model][11]. - -5. Enterprises have not been simply consumers of Linux. Their employees have been [actively participated][12] in the development of Linux. The figure below shows the top-10 corporate sponsors of Linux kernel development, in terms of total commit counts from their employees, as of year 2013. They include commercial Linux distributors (Red Hat, SUSE), chip/embedded system makers (Intel, Texas Instruments, Wolfson), non-profits (Linaro), and other IT power houses (IBM, Samsung, Google). - -![](https://farm6.staticflickr.com/5573/14841856427_a5a1828245_o.png) - -6. The official mascot of Linux is "Tux", a friendly penguin character. The idea of using a cuddly penguin as a mascot/logo was in fact [first conceived and asserted][13] by Linus himself. Why penguin? Personally Linus is fond of penguins, despite the fact that he once was bitten by a ferocious penguin, causing him infected with a disease. - -7. A Linux "distribution" contains the Linux kernel, supporting GNU utilities/libraries, and other third-party applications. According to [distrowatch.com][14], there are a total of 286 actively maintained Linux distrutions. The oldest among them is [Slackware][15] whose very first release 1.0 became available in 1993. - -8. Kernel.org, which is the main repository of Linux source code, was [compromised][16] by an unknown attacker in August, 2011, who managed to tamper with several kernel.org's servers. In an effort to tighten up access policies of the Linux kernel, Linux foundation recently [turned on][17] two-factor authentication at the official Git repositories hosting the Linux kernel. - -9. The dominance of Linux on top 500 supercomputers [continues to rise][18]. As of June 2014, 97% of the world-fastest computers are powered by Linux. - -10. Spacewatch, a research group of Lunar and Planetary Laboratory at the University of Arizona, named several asteroids ([9793 Torvalds][19], [9882 Stallman][20], [9885 Linux][21] and [9965 GNU][22]) after GNU/Linux and their creators, in recognition of the free operating system which was instrumental in their asteroid survey activities. - -11. In the modern history of Linux kernel development, there was a big jump in kernel version: from 2.6 to 3.0. The [renumbering to version 3][23] actually did not signify any major restructuring in kernel code, but was simply to celebrate the 20 year milestone of the Linux kernel. - -12. In 2000, Steve Jobs at Apple Inc. [tried to hire][24] Linus Torvalds to have him drop Linux development and instead work on "Unix for the biggest user base," which was OS X back then. Linus declined the offer. - -13. The [reboot()][25] system call in the Linux kernel requires two magic numbers. The second magic number comes from the [birth dates][26] of Linus Torvalds and his three daughters. - -14. With so many fans of Linux around the world, there are [criticisms][27] on current Linux distributions (mainly desktops), such as limited hardware support, lack of standardization, instability due to short upgrade/release cycles, etc. During the [Linux kernel panel][28] at LinuxCon 2014, Linus was quoted as saying "I still want the desktop" when asked where he thinks Linux should go next. - -If you know any interesting facts about Linux, feel free to share them in the comments. - -Happy birthday, Linux! - --------------------------------------------------------------------------------- - -via: http://xmodulo.com/2014/08/interesting-facts-linux.html - -作者：[Dan Nanni][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://xmodulo.com/author/nanni -[1]:https://groups.google.com/forum/message/raw?msg=comp.os.minix/dlNtH7RRrGA/SwRavCzVE7gJ -[2]:http://developer.android.com/about/index.html -[3]:http://fortune.com/2013/05/06/how-linux-conquered-the-fortune-500/ -[4]:http://www.linuxjournal.com/article/7789 -[5]:http://fcw.com/Articles/2006/05/01/FAA-manages-air-traffic-with-Linux.aspx -[6]:http://thecloudmarket.com/stats -[7]:http://www.gnu.org/gnu/why-gnu-linux.html -[8]:http://www.gnu.org/gnu/gnu-history.html -[9]:http://en.wikipedia.org/wiki/POSIX -[10]:https://www.openhub.net/p/linux/contributors/summary -[11]:https://www.openhub.net/p/linux/estimated_cost -[12]:http://www.linuxfoundation.org/publications/linux-foundation/who-writes-linux-2013 -[13]:http://www.sjbaker.org/wiki/index.php?title=The_History_of_Tux_the_Linux_Penguin -[14]:http://distrowatch.com/search.php?ostype=All&category=All&origin=All&basedon=All¬basedon=None&desktop=All&architecture=All&status=Active -[15]:http://www.slackware.com/info/ -[16]:http://pastebin.com/BKcmMd47 -[17]:http://www.linux.com/news/featured-blogs/203-konstantin-ryabitsev/784544-linux-kernel-git-repositories-add-2-factor-authentication -[18]:http://www.top500.org/statistics/details/osfam/1 -[19]:http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9793 -[20]:http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9882 -[21]:http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9885 -[22]:http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9965 -[23]:https://lkml.org/lkml/2011/5/29/204 -[24]:http://www.wired.com/2012/03/mr-linux/2/ -[25]:http://lxr.free-electrons.com/source/kernel/reboot.c#L199 -[26]:http://www.nndb.com/people/444/000022378/ -[27]:http://linuxfonts.narod.ru/why.linux.is.not.ready.for.the.desktop.current.html -[28]:https://www.youtube.com/watch?v=8myENKt8bD0 \ No newline at end of file diff --git a/sources/talk/20140829 Linux Doesn't Need to Own the Desktop.md b/sources/talk/20140829 Linux Doesn't Need to Own the Desktop.md deleted file mode 100644 index ba28555b79..0000000000 --- a/sources/talk/20140829 Linux Doesn't Need to Own the Desktop.md +++ /dev/null @@ -1,32 +0,0 @@ -Linux Doesn't Need to Own the Desktop -================================================================================ -Linus Torvalds issued Linux 3.17 rc-2 on Monday of this week, and [he deviated from his normal schedule][1] in doing so, because August 25 happens to mark the 23rd anniversary of the original Linux announcement.

He tried to make a copy of ‘Pneumatic Tube System’ which was mostly used to send interoffice mails across offices. This system used a physical network of tubes which used to transport typed mails to secretaries. Each secretary used to have inbox, outbox, drafts, carbon copy paper, folders, address book, paper clips or attachments etc. All these were used to create and process incoming and outgoing mails. - -Shiva also took a note of the common templates like “To”, “From”, “Subject”, “Date”, “Body”, “CC”, “BCC” and so on. All these templates were incorporated in the version of the electronic mail too. Mail was written FORTRAN programming language and Shiva discovered an electronic version of the same. Shiva received many accolades for his extraordinary work and also won a Westinghouse Science Talent Search Award for high school seniors in 1981. Now Smithsonian Institution National Museum of American History (SINMAH) has the official US copyright for “Email”. But there is a controversy that not Ayyadurai but some other people have invented email. - --------------------------------------------------------------------------------- - -via: http://www.efytimes.com/e1/fullnews.asp?edid=147170 - -作者：Sanchari Banerjee -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 \ No newline at end of file diff --git a/sources/talk/20140904 The Masked Avengers.md b/sources/talk/20140904 The Masked Avengers.md deleted file mode 100644 index 0cb5cdaeed..0000000000 --- a/sources/talk/20140904 The Masked Avengers.md +++ /dev/null @@ -1,378 +0,0 @@ -[Translating by SteveArcher] -The Masked Avengers -================================================================================ -> How Anonymous incited online vigilantism from Tunisia to Ferguson. - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_r25419-690.jpg) - -Anyone can join Anonymous simply by claiming affiliation. An anthropologist says that participants “remain subordinate to a focus on the epic win—and, especially, the lulz.” - -Paper Sculpture by Jeff Nishinaka / Photograph by Scott Dunbar - ----------- - -In the mid-nineteen-seventies, when Christopher Doyon was a child in rural Maine, he spent hours chatting with strangers on CB radio. His handle was Big Red, for his hair. Transmitters lined the walls of his bedroom, and he persuaded his father to attach two directional antennas to the roof of their house. CB radio was associated primarily with truck drivers, but Doyon and others used it to form the sort of virtual community that later appeared on the Internet, with self-selected nicknames, inside jokes, and an earnest desire to effect change. - -Doyon’s mother died when he was a child, and he and his younger sister were reared by their father, who they both say was physically abusive. Doyon found solace, and a sense of purpose, in the CB-radio community. He and his friends took turns monitoring the local emergency channel. One friend’s father bought a bubble light and affixed it to the roof of his car; when the boys heard a distress call from a stranded motorist, he’d drive them to the side of the highway. There wasn’t much they could do beyond offering to call 911, but the adventure made them feel heroic. - -Small and wiry, with a thick New England accent, Doyon was fascinated by “Star Trek” and Isaac Asimov novels. When he saw an ad in Popular Mechanics for a build-your-own personal-computer kit, he asked his grandmother to buy it for him, and he spent months figuring out how to put it together and hook it up to the Internet. Compared with the sparsely populated CB airwaves, online chat rooms were a revelation. “I just click a button, hit this guy’s name, and I’m talking to him,” Doyon recalled recently. “It was just breathtaking.” - -At the age of fourteen, he ran away from home, and two years later he moved to Cambridge, Massachusetts, a hub of the emerging computer counterculture. The Tech Model Railroad Club, which had been founded thirty-four years earlier by train hobbyists at M.I.T., had evolved into “hackers”—the first group to popularize the term. Richard Stallman, a computer scientist who worked in M.I.T.’s Artificial Intelligence Laboratory at the time, says that these early hackers were more likely to pass around copies of “Gödel, Escher, Bach” than to incite technological warfare. “We didn’t have tenets,” Stallman said. “It wasn’t a movement. It was just a thing that people did to impress each other.” Some of their “hacks” were fun (coding video games); others were functional (improving computer-processing speeds); and some were pranks that took place in the real world (placing mock street signs near campus). Michael Patton, who helped run the T.M.R.C. in the seventies, told me that the original hackers had unwritten rules and that the first one was “Do no damage.” - -In Cambridge, Doyon supported himself through odd jobs and panhandling, preferring the freedom of sleeping on park benches to the monotony of a regular job. In 1985, he and a half-dozen other activists formed an electronic “militia.” Echoing the Animal Liberation Front, they called themselves the Peoples Liberation Front. They adopted aliases: the founder, a towering middle-aged man who claimed to be a military veteran, called himself Commander Adama; Doyon went by Commander X. Inspired by the Merry Pranksters, they sold LSD at Grateful Dead shows and used some of the cash to outfit an old school bus with bullhorns, cameras, and battery chargers. They also rented a basement apartment in Cambridge, where Doyon occasionally slept. - -Doyon was drawn to computers, but he was not an expert coder. In a series of conversations over the past year, he told me that he saw himself as an activist, in the radical tradition of Abbie Hoffman and Eldridge Cleaver; technology was merely his medium of dissent. In the eighties, students at Harvard and M.I.T. held rallies urging their schools to divest from South Africa. To help the protesters communicate over a secure channel, the P.L.F. built radio kits: mobile FM transmitters, retractable antennas, and microphones, all stuffed inside backpacks. Willard Johnson, an activist and a political scientist at M.I.T., said that hackers were not a transformative presence at rallies. “Most of our work was still done using a bullhorn,” he said. - -In 1992, at a Grateful Dead concert in Indiana, Doyon sold three hundred hits of acid to an undercover narcotics agent. He was sentenced to twelve years in Pendleton Correctional Facility, of which he served five. While there, he developed an interest in religion and philosophy and took classes from Ball State University. - -Netscape Navigator, the first commercial Web browser, was released in 1994, while Doyon was incarcerated. When he returned to Cambridge, the P.L.F. was still active, and their tools had a much wider reach. The change, Doyon recalls, “was gigantic—it was the difference between sending up smoke signals and being able to telegraph someone.” Hackers defaced an Indian military Web site with the words “Save Kashmir.” In Serbia, hackers took down an Albanian site. Stefan Wray, an early online activist, defended such tactics at an “anti-Columbus Day” rally in New York. “We see this as a form of electronic civil disobedience,” he told the crowd. - -In 1999, the Recording Industry Association of America sued Napster, the file-sharing service, for copyright infringement. As a result, Napster was shut down in 2001. Doyon and other hackers disabled the R.I.A.A. site for a weekend, using a Distributed Denial of Service, or DDoS, attack, which floods a site with so much data that it slows down or crashes. Doyon defended his actions, employing the heightened rhetoric of other “hacktivists.” “We quickly came to understand that the battle to defend Napster was symbolic of the battle to preserve a free internet,” he later wrote. - -One day in 2008, Doyon and Commander Adama met at the P.L.F.’s basement apartment in Cambridge. Adama showed Doyon the Web site of the Epilepsy Foundation, on which a link, instead of leading to a discussion forum, triggered a series of flashing colored lights. Some epileptics are sensitive to strobes; out of sheer malice, someone was trying to induce seizures in innocent people. There had been at least one victim already. - -Doyon was incensed. He asked Adama who would do such a thing. - -“Ever hear of a group called Anonymous?” Adama said. - ----------- - -In 2003, Christopher Poole, a fifteen-year-old insomniac from New York City, launched 4chan, a discussion board where fans of anime could post photographs and snarky comments. The focus quickly widened to include many of the Internet’s earliest memes: LOLcats, Chocolate Rain, RickRolls. Users who did not enter a screen name were given the default handle Anonymous. - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_a18505-600.jpg) - -“I need to talk about my inner life.” - -Poole hoped that anonymity would keep things irreverent. “We have no intention of partaking in intelligent discussions concerning foreign affairs,” he wrote on the site. One of the highest values within the 4chan community was the pursuit of “lulz,” a term derived from the acronym LOL. Lulz were often achieved by sharing puerile jokes or images, many of them pornographic or scatological. The most shocking of these were posted on a part of the site labelled /b/, whose users called themselves /b/tards. Doyon was aware of 4chan, but considered its users “a bunch of stupid little pranksters.” Around 2004, some people on /b/ started referring to “Anonymous” as an independent entity. - -It was a new kind of hacker collective. “It’s not a group,” Mikko Hypponen, a leading computer-security researcher, told me—rather, it could be thought of as a shape-shifting subculture. Barrett Brown, a Texas journalist and a well-known champion of Anonymous, has described it as “a series of relationships.” There was no membership fee or initiation. Anyone who wanted to be a part of Anonymous—an Anon—could simply claim allegiance. - -Despite 4chan’s focus on trivial topics, many Anons considered themselves crusaders for justice. They launched vigilante campaigns that were purposeful, if sometimes misguided. More than once, they posed as underage girls in order to entrap pedophiles, whose personal information they sent to the police. Other Anons were apolitical and sowed chaos for the lulz. One of them posted images on /b/ of what looked like pipe bombs; another threatened to blow up several football stadiums and was arrested by the F.B.I. In 2007, a local news affiliate in Los Angeles called Anonymous “an Internet hate machine.” - -In January, 2008, Gawker Media posted a video in which Tom Cruise enthusiastically touted the benefits of Scientology. The video was copyright-protected, and the Church of Scientology sent a cease-and-desist letter to Gawker, asking that the video be removed. Anonymous viewed the church’s demands as attempts at censorship. “I think it’s time for /b/ to do something big,” someone posted on 4chan. “I’m talking about ‘hacking’ or ‘taking down’ the official Scientology Web site.” An Anon used YouTube to issue a “press release,” which included stock footage of storm clouds and a computerized voice-over. “We shall proceed to expel you from the Internet and systematically dismantle the Church of Scientology in its present form,” the voice said. “You have nowhere to hide.” Within a few weeks, the YouTube video had been viewed more than two million times. - -Anonymous had outgrown 4chan. The hackers met in dedicated Internet Relay Chat channels, or I.R.C.s, to coördinate tactics. Using DDoS attacks, they caused the main Scientology Web site to crash intermittently for several days. Anons created a “Google bomb,” so that a search for “dangerous cult” would yield the main Scientology site at the top of the results page. Others sent hundreds of pizzas to Scientology centers in Europe, and overwhelmed the church’s Los Angeles headquarters with all-black faxes, draining the machines of ink. The Church of Scientology, an organization that reportedly has more than a billion dollars in assets, could withstand the depletion of its ink cartridges. But its leaders, who had also received death threats, contacted the F.B.I. to request an investigation into Anonymous. - -On March 15, 2008, several thousand Anons marched past Scientology churches in more than a hundred cities, from London to Sydney. In keeping with the theme of anonymity, the organizers decided that all the protesters should wear versions of the same mask. After considering Batman, they settled on the Guy Fawkes mask worn in “V for Vendetta,” a dystopian movie from 2005. “It was available in every major city, in large quantities, for cheap,” Gregg Housh, one of the organizers of the protests and a well-known Anon, told me. The mask was a caricature of a man with rosy cheeks, a handlebar mustache, and a wide grin. - -Anonymous did not “dismantle” the Church of Scientology. Still, the Tom Cruise video remained online. Anonymous had proved its tenacity. The collective adopted a bombastic slogan: “We are Legion. We do not forgive. We do not forget. Expect us.” - ----------- - -In 2010, Doyon moved to Santa Cruz, California, to join a local movement called Peace Camp. Using wood that he stole from a lumberyard, he built a shack in the mountains. He borrowed WiFi from a nearby mansion, drew power from salvaged solar panels, and harvested marijuana, which he sold for cash. - -At the time, the Peace Camp activists were sleeping on city property as a protest against a Santa Cruz anti-homelessness law that they considered extreme. Doyon appeared at Peace Camp meetings and offered to promote their cause online. He had an unkempt red beard and wore a floppy beige hat and quasi-military fatigues. Some of the activists called him Curbhugger Chris. - -Kelley Landaker, a member of Peace Camp, spoke with Doyon several times about hacking. Doyon sometimes bragged about his technical aptitude, but Landaker, an expert programmer, was unimpressed. “He was more of a spokesman than a hands-on-the-keyboard type of person,” Landaker told me. But the movement needed a passionate leader more than it needed a coder. “He was very enthusiastic and very outspoken,” Robert Norse, also a member of Peace Camp, told me. “He created more media attention for the issue than anyone I’ve seen, and I’ve been doing this for twenty years.” - -Commander Adama, Doyon’s superior in the P.L.F., who still lived in Cambridge and communicated with him via e-mail, had ordered Doyon to monitor Anonymous. Doyon’s brief was to observe their methods and to recruit members to the P.L.F. Recalling his revulsion at the Epilepsy Foundation hack, Doyon initially balked. Adama argued that the malicious hackers were a minority within Anonymous, and that the collective might inspire powerful new forms of activism. Doyon was skeptical. “The biggest movement in the world is going to come from 4chan?” he said. But, out of loyalty to the P.L.F., he obeyed Adama. - -Doyon spent much of his time at the Santa Cruz Coffee Roasting Company, a café downtown, hunched over an Acer laptop. The main Anonymous I.R.C. did not require a password. Doyon logged in using the name PLF and followed along. Over time, he discovered back channels where smaller, more dedicated groups of Anons had dozens of overlapping conversations. To participate, you had to know the names of the back channels, which could be changed to deflect intruders. It was not a highly secure system, but it was adaptable. “These simultaneous cabals keep centralization from happening,” Gabriella Coleman, an anthropologist at McGill University, told me. - -Some Anons proposed an action called Operation Payback. As the journalist Parmy Olson wrote in a 2012 book, “We Are Anonymous,” Operation Payback started as another campaign in support of file-sharing sites like the Pirate Bay, a successor to Napster, but the focus soon broadened to include political speech. In late 2010, at the behest of the State Department, several companies, including MasterCard, Visa, and PayPal, stopped facilitating donations to WikiLeaks, the vigilante organization that had released hundreds of thousands of diplomatic cables. In an online video, Anonymous called for revenge, promising to lash out at the companies that had impeded WikiLeaks. Doyon, attracted by the anti-corporate spirit of the project, decided to participate. - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_a18473-600.jpg) - -During Operation Payback, in early December, Anonymous directed new recruits, or noobs, to a flyer headed “How to Join the Fucking Hive,” in which participants were instructed to “FIX YOUR GODDAMN INTERNET. THIS IS VERY FUCKING IMPORTANT.” They were also asked to download Low Orbit Ion Cannon, an easy-to-use tool that is publicly available. Doyon downloaded the software and watched the chat rooms, waiting for a cue. When the signal came, thousands of Anons fired at once. Doyon entered a target URL—say, www.visa.com—and, in the upper-right corner, clicked a button that said “IMMA CHARGIN MAH LAZER.” (The operation also relied on more sophisticated hacking.) Over several days, Operation Payback disabled the home pages of Visa, MasterCard, and PayPal. In court filings, PayPal claimed that the attack had cost the company five and a half million dollars. - -To Doyon, this was activism made tangible. In Cambridge, protesting against apartheid, he could not see immediate results; now, with the tap of a button, he could help sabotage a major corporation’s site. A banner headline on the Huffington Post read “MasterCard DOWN.” One gloating Anon tweeted, “There are some things WikiLeaks can’t do. For everything else, there’s Operation Payback.” - ----------- - -In the fall of 2010, the Peace Camp protests ended. With slight concessions, the anti-homelessness law remained in effect. Doyon hoped to use the tactics of Anonymous to reinvigorate the movement. He recalls thinking, “I could wield Anonymous against this tiny little city government and they would just be fucking wrecked. Plan was we were finally going to solve this homelessness problem, once and for all.” - -Joshua Covelli, a twenty-five-year-old Anon who went by the nickname Absolem, admired Doyon’s decisiveness. “Anonymous had been this clusterfuck of chaos,” Covelli told me. With Commander X, “there seemed to be a structure set up.” Covelli worked as a receptionist at a college in Fairborn, Ohio, and knew nothing about Santa Cruz politics. But when Doyon asked for help with Operation Peace Camp, Covelli e-mailed back immediately: “I’ve been waiting to join something like that my entire life.” - -Doyon, under the name PLF, invited Covelli into a private I.R.C.: - -> Absolem: Sorry to be so rude . . . Is PLF part of Anonymous or separate? -> -> Absolem: I was just asking because you all seem very organized in chat. -> -> PLF: You are not in the least rude. I am pleased to meet you. PLF is 22 year old hacker group originally from Boston. I started hacking in 81, not with computers but PBX (telephones). -> -> PLF: We are all older 40 or over. Some of us are former military or intelligence. One of us, Commander Adama is currently sought by an alphabet soup of cops and spooks and in hiding. -> -> Absolem: Wow that’s legit. I am really interested in helping this out in some way and Anonymous just seems too chaotic. I have some computer skills but very noob in hacking. I have some tools but no Idea how to use them. - -With ritual solemnity, Doyon accepted Covelli’s request to join the P.L.F.: - -> PLF: Encrypt the fuck out of all sensitive material that might incriminate you. -> -> PLF: Yep, work with any PLFer to get a message to me. Call me . . . Commander X for now. - -In 2012, the Associated Press called Anonymous “a group of expert hackers”; Quinn Norton, in Wired, wrote that “Anonymous had figured out how to infiltrate anything,” resulting in “a wild string of brilliant hacks.” In fact some Anons are gifted coders, but the vast majority possess little technical skill. Coleman, the anthropologist, told me that only a fifth of Anons are hackers—the rest are “geeks and protesters.” - -On December 16, 2010, Doyon, as Commander X, sent an e-mail to several reporters. “At exactly noon local time tomorrow, the Peoples Liberation Front and Anonymous will remove from the Internet the Web site of the Santa Cruz County government,” he wrote. “And exactly 30 minutes later, we will return it to normal function.” - -The data-center staff for Santa Cruz County saw the warning and scrambled to prepare for the attack. They ran security scans on the servers and contacted A.T. & T., the county’s Internet provider, which suggested that they alert the F.B.I. - -The next day, Doyon entered a Starbucks and booted up his laptop. Even for a surfing town, he was notably eccentric: a homeless-looking man wearing fatigues and typing furiously. Covelli met him in a private chat room. - -> PLF: Go to Forum, sign in—and look at top right menu bar “chat.” Thats Ops for today. Thank you for standing with us. -> -> Absolem: Anything for PLF, sir. - -They both opened DDoS software. Though only a handful of people were participating in Operation Peace Camp, Doyon gave orders as if he were addressing legions of troops: - -> PLF: ATTENTION: Everyone who supports the PLF or considers us their friend—or who cares about defeating evil and protecting the innocent: Operation Peace Camp is LIVE and an action is underway. TARGET: www.co.santa-cruz.ca.us. Fire At Will. Repeat: FIRE! -> -> Absolem: got it, sir. - -The data-center staff watched their servers, which showed a flurry of denial-of-service requests. Despite their best efforts, the site crashed. Twenty-five minutes later, Doyon decided that he had made his point. He typed “CEASE FIRE,” and the county’s site flickered back to life. (Despite the attack, the city’s anti-homelessness law did not change.) - -Doyon hardly had time to celebrate before he grew anxious. “I got to leave,” he typed to Covelli. He fled to his shack in the mountains. Doyon was right to be wary: an F.B.I. agent had been snooping in the I.R.C. The F.B.I. obtained a warrant to search Doyon’s laptop. - -A few weeks later, Doyon’s food ran out, and he returned to town. While he was at the Santa Cruz Coffee Roasting Company, two federal agents entered the shop. They brought him to the county police station. Doyon called Ed Frey, a lawyer and the founder of Peace Camp, who met him at the station. Doyon told Frey about his alter ego as Commander X. - -Doyon was released, but the F.B.I. kept his laptop, which was full of incriminating evidence. Frey, a civil-rights lawyer who knew little about cybersecurity, drove Doyon back to his hillside encampment. “What are you going to do?” Frey asked. - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_a18447-600.jpg) - -“Zach is in the gifted-and-talented-and-you’re-not class.” - -He spoke in cinematic terms. “Run like hell,” he said. “I will go underground, try to stay free as long as I can, and keep fighting the bastards any way possible.” Frey gave him two twenty-dollar bills and wished him luck. - ----------- - -Doyon hitchhiked to San Francisco and stayed there for three months. He spent his days at Coffee to the People, a quirky café in the Haight-Ashbury district, where he would sit for hours in front of his computer, interrupted only by outdoor cigarette breaks. - -In January, 2011, Doyon contacted Barrett Brown, the journalist and Anon. “What are we going to do next?” Doyon asked. - -“Tunisia,” Brown said. - -“Yeah, it’s a country in the Middle East,” Doyon said. “What about it?” - -“We’re gonna take down its dictator,” Brown said. - -“Oh, they have a dictator?” Doyon said. - -A couple of days later, Operation Tunisia began. Doyon volunteered to spam Tunisian government e-mail addresses in an attempt to clog their servers. “I would take the text of the press release for that op and just keep sending it over and over again,” he said. “Sometimes, I was so busy that I would just put ‘fuck you’ and send it.” In one day, the Anons brought down the Web sites of the Tunisian Stock Exchange, the Ministry of Industry, the President, and the Prime Minister. They replaced the Web page of the President’s office with an image of a pirate ship and the message “Payback is a bitch, isn’t it?” - -Doyon often spoke of his online battles as if he had just crawled out of a foxhole. “Dude, I turned black from doing it,” he told me. “My face, from all the smoke—it would cling to me. I would look up and I would literally be like a raccoon.” Most nights, he camped out in Golden Gate Park. “I would look at myself in the mirror and I’d be like, O.K., it’s been four days—maybe I should eat, bathe.” - -Anonymous-affiliated operations continued to be announced on YouTube: Operation Libya, Operation Bahrain, Operation Morocco. As protesters filled Tahrir Square, Doyon participated in Operation Egypt. A Facebook page disseminated information, including links to a “care package” for protesters on the ground. The package, distributed through the file-sharing site Megaupload, contained encryption software and a primer on defending against tear gas. Later, when the Egyptian government disabled Internet and cellular networks within the country, Anonymous helped the protesters find alternative ways to get online. - -In the summer of 2011, Doyon succeeded Adama as Supreme Commander of the P.L.F. Doyon recruited roughly half a dozen new members and attempted to position the P.L.F. as an élite squad within Anonymous. Covelli became one of his technical advisers. Another hacker, Crypt0nymous, made YouTube videos; others did research or assembled electronic care packages. Unlike Anonymous, the P.L.F. had a strict command structure. “X always called the shots on everything,” Covelli said. “It was his way or no way.” A hacker who founded a blog called AnonInsiders told me over encrypted chat that Doyon was willing to act unilaterally—a rare thing within Anonymous. “When we wanted to start an op, he didn’t mind if anyone would agree or not,” he said. “He would just write the press release by himself, list all the targets, open the I.R.C. channel, tell everyone to go in there, and start the DDoSing.” - -Some Anons viewed the P.L.F. as a vanity project and Doyon as a laughingstock. “He’s known for his exaggeration,” Mustafa Al-Bassam, an Anon who went by Tflow, told me. Others, even those who disapproved of Doyon’s egotism, grudgingly acknowledged his importance to the Anonymous movement. “He walks that tough line of sometimes being effective and sometimes being in the way,” Gregg Housh said, adding that he and other prominent Anons had faced similar challenges. - -Publicly, Anonymous persists in claiming to be non-hierarchical. In “We Are Legion,” a 2012 documentary about Anonymous by Brian Knappenberger, one activist uses the metaphor of a flock of birds, with various individuals taking turns drifting toward the front. Gabriella Coleman told me that, despite such claims, something resembling an informal leadership class did emerge within Anonymous. “The organizer is really important,” she said. “There are four or five individuals who are really good at it.” She counted Doyon among them. Still, Anons tend to rebel against institutional structure. In a forthcoming book about Anonymous, “Hacker, Hoaxer, Whistleblower, Spy,” Coleman writes that, among Anons, “personal identity and the individual remain subordinate to a focus on the epic win—and, especially, the lulz.” - -Anons who seek individual attention are often dismissed as “egofags” or “namefags.” (Many Anons have yet to outgrow their penchant for offensive epithets.) “There are surprisingly few people who violate the rule” against attention-seeking, Coleman says. “Those who do, like X, are marginalized.” Last year, in an online discussion forum, a commenter wrote, “I stopped reading his BS when he started comparing himself to Batman.” - -Peter Fein, an online activist known by the nickname n0pants, was among the many Anons who were put off by Doyon’s self-aggrandizing rhetoric. Fein browsed the P.L.F. Web site, which featured a coat of arms and a manifesto about the group’s “epic battle for the very soul of humanity.” Fein was dismayed to find that Doyon had registered the site using his real name, leaving himself and possibly other Anons vulnerable to prosecution. “I’m basically okay with people DDoSing,” Fein recalls telling Doyon over private chat. “But if you’re going to do it, you’ve got to cover your ass.” - -On February 5, 2011, the Financial Times reported that Aaron Barr, the C.E.O. of a cybersecurity firm called HBGary Federal, had identified the “most senior” members of Anonymous. Barr’s research suggested that one of the top three was Commander X, a hacker based in California, who could “manage some significant firepower.” Barr contacted the F.B.I. and offered to share his work with them. - -Like Fein, Barr had seen that the P.L.F. site was registered to Christopher Doyon at an address on Haight Street. Based on Facebook and I.R.C. activity, Barr concluded that Commander X was Benjamin Spock de Vries, an online activist who had lived near the Haight Street address. Barr approached de Vries on Facebook. “Please tell the folks there that I am not out to get you guys,” Barr wrote. “Just want the ‘leadership’ to know what my intent is.” - -“ ‘Leadership’ lmao,” de Vries responded. - -Days after the Financial Times story appeared, Anonymous struck back. HBGary Federal’s Web site was defaced. Barr’s personal Twitter account was hijacked, thousands of his e-mails were leaked online, and Anons released his address and other personal information—a punishment known as doxing. Barr resigned from HBGary Federal within the month. - ----------- - -In April, 2011, Doyon left San Francisco and hitchhiked around the West, camping in parks at night and spending his days at Starbucks outlets. In his backpack he kept his laptop, his Guy Fawkes mask, and several packs of Pall Malls. - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_a18563-600.jpg) - -“This is what I learned during my summer at TED camp.” - -He followed internal Anonymous news. That spring, six élite Anons, all of whom had been instrumental in deflecting Barr’s investigation, formed a group called Lulz Security, or LulzSec. As their name indicated, they felt that Anonymous had become too self-serious; they aimed to bring the lulz back. While Anonymous continued supporting Arab Spring protesters, LulzSec hacked the Web site of PBS and posted a fake story claiming that the late rapper Tupac Shakur was alive in New Zealand. - -Anons often share text through the Web site Pastebin.com. On the site, LulzSec issued a statement that read, “It has come to our unfortunate attention that NATO and our good friend Barrack Osama-Llama 24th-century Obama have recently upped the stakes with regard to hacking. They now treat hacking as an act of war.” The loftier the target, the greater the lulz. On June 15th, LulzSec took credit for crashing the C.I.A.’s Web site, tweeting, “Tango down—cia.gov—for the lulz.” - -On June 20, 2011, Ryan Cleary, a nineteen-year-old member of LulzSec, was arrested for the DDoS attacks on the C.I.A. site. The next month, F.B.I. agents arrested fourteen other hackers for DDoS attacks on PayPal seven months earlier. Each of the PayPal Fourteen, as they became known, faced fifteen years in prison and a five-hundred-thousand-dollar fine. They were charged with conspiracy and intentional damage to protected computers under the Computer Fraud and Abuse Act. (The law allows for wide prosecutorial discretion and was widely criticized after Aaron Swartz, an Internet activist who was facing thirty-five years in prison, committed suicide last year.) - -A petition was circulated on behalf of Jake (Topiary) Davis, a member of LulzSec, who needed help paying his legal fees. Doyon entered an I.R.C. to promote Davis’s cause: - -> CommanderX: Please sign the petition and help Topiary… -> -> toad: you are an attention whore -> -> toad: so you get attention -> -> CommanderX: Toad your an asshole. -> -> katanon: sigh - -Doyon had grown increasingly brazen. He DDoS’ed the Web site of the Chamber of Commerce of Orlando, Florida, after activists there were arrested for feeding the homeless. He launched the attacks from public WiFi networks, using his personal laptop, without making much effort to cover his tracks. “That’s brave but stupid,” a senior member of the P.L.F. who asked to be called Kalli told me. “He didn’t seem to care if he was caught. He was a suicide hacker.” - -Two months later, Doyon participated in a DDoS strike against San Francisco’s Bay Area Rapid Transit, protesting an incident in which a BART police officer had killed a homeless man named Charles Hill. Doyon appeared on the “CBS Evening News” to defend the action, his voice disguised and his face obscured by a bandanna. He compared DDoS attacks to civil disobedience. “It’s no different, really, than taking up seats at the Woolworth lunch counters,” he said. Bob Schieffer, the CBS anchor, snickered and said, “It’s not quite the civil-rights movement, as I see it.” - -On September 22, 2011, in a coffee shop in Mountain View, California, Doyon was arrested and charged with causing intentional damage to a protected computer. He was detained for a week and released on bond. Two days later, against his lawyer’s advice, he called a press conference on the steps of the Santa Cruz County Courthouse. His hair in a ponytail, he wore dark sunglasses, a black pirate hat, and a camouflage bandanna around his neck. - -In characteristically melodramatic fashion, Doyon revealed his identity. “I am Commander X,” he told reporters. He raised his fist. “I am immensely proud, and humbled to the core, to be a part of the idea called Anonymous.” He told a journalist, “All you need to be a world-class hacker is a computer and a cool pair of sunglasses. And the computer is optional.” - -Kalli worried that Doyon was placing his ego above the safety of other Anons. “It’s the weakest link in the chain that ends up taking everyone down,” he told me. Josh Covelli, the Anon who had been eager to help Doyon with Operation Peace Camp, told me that his “jaw dropped” when he saw a video of Doyon’s press conference online. “The way he presented himself and the way he acted had become more unhinged,” Covelli said. - -Three months later, Doyon’s pro-bono lawyer, Jay Leiderman, was in a federal court in San Jose. Leiderman had not heard from Doyon in a couple of weeks. “I’m inquiring as to whether there’s a reason for that,” the judge said. Leiderman had no answer. Doyon was absent from another hearing two weeks later. The prosecutor stated the obvious: “It appears as though the defendant has fled.” - ----------- - -Operation Xport was the first Anonymous operation of its kind. The goal was to smuggle Doyon, now a fugitive wanted for two felonies, out of the country. The coördinators were Kalli and a veteran Anon who had met Doyon at an acid party in Cambridge during the eighties. A retired software executive, he was widely respected within Anonymous. - -Doyon’s ultimate destination was the software executive’s house, deep in rural Canada. In December, 2011, he hitchhiked to San Francisco and made his way to an Occupy encampment downtown. He found his designated contact, who helped him get to a pizzeria in Oakland. At 2 A.M., Doyon, using the pizzeria’s WiFi, received a message on encrypted chat. - -“Are you near a window?” the message read. - -“Yeah,” Doyon typed. - -“Look across the street. Do you see the green mailbox? In exactly fifteen minutes, go and stand next to that mailbox and set your backpack down, and lay your mask on top of it.” - -For a few weeks, Doyon shuttled among safe houses in the Bay Area, following instructions through encrypted chat. Eventually, he took a Greyhound bus to Seattle, where he stayed with a friend of the software executive. The friend, a wealthy retiree, spent hours using Google Earth to help Doyon plot a route to Canada. They went to a camping-supplies store, and the friend spent fifteen hundred dollars on gear for Doyon, including hiking boots and a new backpack. Then he drove Doyon two hours north and dropped him off in a remote area, several hundred miles from the border, where Doyon met up with Amber Lyon. - -Months earlier, Lyon, a broadcast journalist, had interviewed Doyon for a CNN segment about Anonymous. He liked her report, and they stayed in touch. Lyon asked to join Doyon on his escape, to shoot footage for a possible documentary. The software executive thought that it was “nuts” to take the risk, but Doyon invited her anyway. “I think he wanted to make himself a face of the movement,” Lyon told me. For four days, she filmed him as he hiked north, camping in the woods. “It wasn’t very organized,” Lyon recalls. “He was functionally homeless, so he just kind of wandered out of the country.” - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_a18506-600.jpg) - -“This is the barn where we keep our feelings. If a feeling comes to you, bring it out here and lock it up.” - -On February 11, 2012, a press release appeared on Pastebin. “The PLF is delighted to announce that Commander X, aka Christopher Mark Doyon, has fled the jurisdiction of the USA and entered the relative safety of the nation of Canada,” it read. “The PLF calls upon the government of the USA to come to its senses and cease the harassment, surveillance—and arrest of not only Anonymous, but all activists.” - ----------- - -In Canada, Doyon spent a few days with the software executive in a small house in the woods. In a chat with Barrett Brown, Doyon was effusive. - -> BarrettBrown: you have enough safe houses, etc? . . . -> -> CommanderX: Yes I am good here, money and houses a plenty in Canada. -> -> CommanderX: Amber Lyon asked me on camera about you. -> -> CommanderX: I think you will like my reply, and fuck the trolls Barrett. I have always loved you and always will. -> -> CommanderX: :-) -> -> CommanderX: I told her you were a hero. -> -> BarrettBrown: you’re a hero . . . -> -> BarrettBrown: glad you’re safe for now -> -> BarrettBrown: let me know if you need anything -> -> CommanderX: I am, and if this works we can get others out to . . . . -> -> BarrettBrown: good, we’re going to need that - -Ten days after Doyon’s escape, the Wall Street Journal reported that Keith Alexander, then the N.S.A. and U.S. Cyber Command director, had held classified meetings in the White House and elsewhere during which he expressed concern about Anonymous. Within two years, Alexander warned, the group might be capable of destabilizing national power grids. General Martin Dempsey, the chairman of the Joint Chiefs of Staff, told the Journal that an enemy of the U.S. “could give cyber malware capability to some fringe group,” adding, “We have to get after this.” - -On March 8th, a briefing on cybersecurity was held for members of Congress at a Sensitive Compartmented Information Facility near the Capitol Building. Many of the country’s top security officials attended the briefing, including Alexander, Dempsey, Robert Mueller, the head of the F.B.I., and Janet Napolitano, the Secretary of Homeland Security. Attendees were shown a computer simulation of what a cyberattack on the Eastern Seaboard’s electrical supply might look like. Anonymous was not yet capable of mounting an attack on this scale, but security officials worried that they might join forces with other, more sophisticated groups. “As we were dealing with this ever-increasing presence on the Net and ever-increasing risk, the government nuts and bolts were still being worked out,” Napolitano told me. When discussing potential cybersecurity threats, she added, “We often used Anonymous as Exhibit A.” - -Anonymous might be the most powerful nongovernmental hacking collective in the world. Even so, it has never demonstrated an ability or desire to damage any key elements of public infrastructure. To some cybersecurity experts, the dire warnings about Anonymous sounded like fearmongering. “There’s a big gap between declaring war on Orlando and pulling off a Stuxnet attack,” James Andrew Lewis, a senior fellow at the Center for Strategic and International Studies, told me, referring to the elaborate cyberstrike carried out by the U.S. and Israel against Iranian nuclear sites in 2007. Yochai Benkler, a professor at Harvard Law School, told me, “What we’ve seen is the use of drumbeating as justification for major defense spending of a form that would otherwise be hard to justify.” - -Keith Alexander, who recently retired from the government, declined to comment for this story, as did representatives from the N.S.A., the F.B.I., the C.I.A., and the D.H.S. Although Anons have never seriously compromised government computer networks, they have a record of seeking revenge against individuals who anger them. Andy Purdy, the former head of the national-cybersecurity division of the D.H.S., told me that “a fear of retaliation,” both institutional and personal, prevents government representatives from speaking out against Anonymous. “Everyone is vulnerable,” he said. - ----------- - -On March 6, 2012, Hector Xavier Monsegur, a key member of LulzSec with the screen name Sabu, was revealed to be an F.B.I. informant. In exchange for a reduced sentence, Monsegur had spent several months undercover, helping to gather evidence against other LulzSec members. The same day, five leading Anons were arrested and charged with several crimes, including computer conspiracy. An F.B.I. official told Fox News, “This is devastating to the organization. We’re chopping off the head of LulzSec.” Over the next ten months, Barrett Brown was indicted on seventeen federal charges, most of which were later dropped. (He will be sentenced in October.) - -Doyon was distraught, but he continued to hack—and to seek attention. He appeared, masked, at a Toronto screening of a documentary about Anonymous. He gave an interview to a reporter from the National Post and boasted, without substantiation, “We have access to every classified database in the U.S. government. It’s a matter of when we leak the contents of those databases, not if.” - -In January, 2013, after another Anon started an operation about the rape of a teen-age girl in Steubenville, Ohio, Doyon repurposed LocalLeaks, a site he had created two years earlier, as a clearinghouse for information about the rape. Like many Anonymous efforts, LocalLeaks was both influential and irresponsible. It was the first site to widely disseminate the twelve-minute video of a Steubenville High School graduate joking about the rape, which inflamed public outrage about the story. But the site also perpetuated several false rumors about the case and it failed to redact a court document, thus accidentally revealing the rape victim’s name. Doyon admitted to me that his strategy of releasing unexpurgated materials was controversial, but he recalled thinking, “We could either gut the Steubenville Files . . . or we could release everything we know, basically, with the caveat, Hey, you’ve got to trust us.” - -In May, 2013, the Rustle League, a group of online trolls who often provoke Anonymous, hacked Doyon’s Twitter account. Shm00p, one of the leaders of Rustle League, told me, “We’re not trying to cause harm to the guy, but, just, the shit he was saying—it was comical to me.” The Rustle League implanted racist and anti-Semitic messages into Doyon’s account, such as a link to www.jewsdid911.org. - -On August 27, 2013, Doyon posted a note announcing his retirement from Anonymous. “My entire life has been dedicated to fighting for justice and freedom,” he wrote. “ ‘Commander X’ may be invincible, but I am extremely ill from the exhaustion and stress of fighting in this epic global cyber war.” Reactions varied from compassion (“you deserve a rest”) to ridicule (“poor crazy old gnoll. Maybe he has some time for bathing now”). Covelli told me, “The persona has consumed him to the point where he can’t handle it anymore.” - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_roberts-1998-08-17-600.jpg) - -August 17, 1998 “We still have Paris? Just thought I’d check.” - ----------- - -The first Million Mask March took place on November 5, 2013. Several thousand people marched in support of Anonymous, in four hundred and fifty cities around the world. In a sign of how deeply Anonymous had penetrated popular culture, one protester in London removed his Guy Fawkes mask to reveal that he was the actor Russell Brand. - -While I attended the rally in Washington, D.C., Doyon watched a livestream in Canada. I exchanged e-mails with him on my phone. “It is so surreal to sit here, sidelined and out of the game—and watch something that you helped create turn into this,” he wrote. “At least it all made a difference.” - -We arranged a face-to-face meeting. Doyon insisted that I submit to elaborate plans made over encrypted chat. I was to fly to an airport several hours away, rent a car, drive to a remote location in Canada, and disable my phone. - -I found him in a small, run-down apartment building in a quiet residential neighborhood. He wore a green Army-style jacket and a T-shirt featuring one of Anonymous’s logos: a black-suited man with a question mark instead of a face. The apartment was sparsely furnished and smelled of cigarette smoke. He discussed U.S. politics (“I have not voted in many elections—it’s all a rigged game”), militant Islam (“I believe that people in the Nigerian government essentially colluded to create a completely phony Al Qaeda affiliate called Boko Haram”), and his tenuous position within Anonymous (“These people who call themselves trolls are really just rotten, mean, evil people”). - -Doyon had shaved his beard, and he looked gaunt. He told me that he was ill and that he rarely went outside. On his small desk were two laptops, a stack of books about Buddhism, and an overflowing ashtray. A Guy Fawkes mask hung on an otherwise bare yellow wall. He told me, “Underneath the whole X persona is a little old man who is in absolute agony at times.” - -This past Christmas, the founder of the news site AnonInsiders visited him, bearing pie and cigarettes. Doyon asked the friend to succeed him as Supreme Commander of the P.L.F., offering “the keys to the kingdom”—all his passwords, as well as secret files relating to several Anonymous operations. The friend gently declined. “I have a life,” he told me. - ----------- - -On August 9, 2014, at 5:09 P.M. local time, Kareem (Tef Poe) Jackson, a rapper and activist from Dellwood, Missouri, a suburb of St. Louis, tweeted about a crisis unfolding in a neighboring town. “Basically martial law is taking place in Ferguson all perimeters blocked coming and going,” he wrote. “National and international friends Help!!!” Five hours earlier in Ferguson, an unarmed eighteen-year-old African-American, Michael Brown, had been shot to death by a white police officer. The police claimed that Brown had reached for the officer’s gun. Brown’s friend Dorian Johnson, who was with him at the time, said that Brown’s only offense was refusing to leave the middle of the street. - -Within two hours, Jackson received a reply from a Twitter account called CommanderXanon. “You can certainly expect us,” the message read. “See if you can get us some live streams going, that would be useful.” In recent weeks, Doyon, still in Canada, had come out of retirement. In June, two months before his fiftieth birthday, he quit smoking (“#hacktheaddiction #ecigaretteswork #old,” he later tweeted). The following month, after fighting broke out in Gaza, he tweeted in support of Anonymous’s Operation Save Gaza, a series of DDoS strikes against Israeli Web sites. Doyon found the events in Ferguson even more compelling. Despite his idiosyncrasies, he had a knack for being early to a cause. - -“Start collecting URLs for cops, city government,” Doyon tweeted. Within ten minutes, he had created an I.R.C. channel. “Anonymous Operation Ferguson is engaged,” he tweeted. Only two people retweeted the message. - -The next morning, Doyon posted a link to a rudimentary Web site, which included a message to the people of Ferguson—“You are not alone, we will support you in every way possible”—and an ultimatum to the police: “If you abuse, harass or harm in any way the protesters in Ferguson, we will take every Web based asset of your departments and governments off line. That is not a threat, it is a promise.” Doyon appealed to the most visible Anonymous Twitter account, YourAnonNews, which has 1.3 million followers. “Please support Operation Ferguson,” he wrote. A minute later, YourAnonNews complied. That day, the hashtag #OpFerguson was tweeted more than six thousand times. - -The crisis became a top news story, and Anons rallied around Operation Ferguson. As with the Arab Spring operations, Anonymous sent electronic care packages to protesters on the ground, including a riot guide (“Pick up the gas emitter and lob it back at the police”) and printable Guy Fawkes masks. As Jackson and other protesters marched through Ferguson, the police attempted to subdue them with rubber bullets and tear gas. “It looked like a scene from a Bruce Willis movie,” Jackson told me. “Barack Obama hasn’t supported us to the degree Anonymous has,” he said. “It’s comforting to know that someone out there has your back.” - -One site, www.opferguson.com, turned out to be a honeypot—a trap designed to collect the Internet Protocol addresses of visitors and turn them over to law-enforcement agencies. Some suspected Commander X of being a government informant. In the #OpFerguson I.R.C., someone named Sherlock wrote, “Everyone got me scared clicking links. Unless it’s from a name I’ve seen a lot, I just avoid them.” - -Protesters in Ferguson asked the police to reveal the name of the officer who had shot Brown. Several times, Anons echoed this demand. Someone tweeted, “Ferguson police better release the shooter’s name before Anonymous does the work for them.” In a community meeting on August 12th, Jon Belmar, the Chief of the St. Louis Police Department, refused. “We do not do that until they’re charged with an offense,” he said. - -In retaliation, a hacker with the handle TheAnonMessage tweeted a link to what he claimed was a two-hour audio file of a police radio scanner, recorded around the time of Brown’s death. TheAnonMessage also doxed Belmar, tweeting what he purported to be the police chief’s home address, phone number, and photographs of his family—one of his son sleeping on a couch, another of Belmar posing with his wife. “Nice photo, Jon,” TheAnonMessage tweeted. “Your wife actually looks good for her age. Have you had enough?” An hour later, TheAnonMessage threatened to dox Belmar’s daughter. - -Richard Stallman, the first-generation hacker from M.I.T., told me that though he supports many of Anonymous’s causes, he considered these dox attacks reprehensible. Even internally, TheAnonMessage’s actions were divisive. “Why bother doxing people who weren’t involved?” one Anon asked over I.R.C., adding that threatening Belmar’s family was “beyond stupid.” But TheAnonMessage and other Anons continued to seek information that could be used in future dox attacks. The names of Ferguson Police Department employees were available online, and Anons scoured the Internet, trying to suss out which of the officers had killed Brown. - -![](http://www.newyorker.com/wp-content/uploads/2014/09/140908_steig-1999-04-12-600.jpg) - -April 12, 1999“Which thing do I press?” - -In the early morning of August 14th, a few Anons became convinced, based on Facebook photos and other disparate clues, that Brown’s shooter was a thirty-two-year-old man named Bryan Willman. According to a transcript of an I.R.C., one Anon posted a photo of Willman with a swollen face; another noted, “The shooter claimed to have been hit in the face.” Another user, Anonymous|11057, acknowledged that his suspicion of Willman involved “a leap of probably bad logic.” Still, he wrote, “i just can’t shake it. i really truly honestly and without a shred of hard evidence think it’s him.” - -TheAnonMessage seemed amused by the conversation, writing, “#RIPBryanWillman.” Other Anons urged caution. “Please be sure,” Anonymous|2252 wrote. “It’s not just about a man’s life, Anon can easily be turned on by the public if something truly unjust comes of this.” - -The debate went on for more than an hour. Several Anons pointed out that there was no way to confirm that Willman had ever been a Ferguson police officer. - -> Anonymous|3549: @gs we still don’t have a confirmation that bry is even on PD -> -> Intangir: tensions are high enough right now where there is a slim chance someone might care enough to kill him -> -> Anonymous|11057: the only real way to get a confirmation would be an eyewitness report from the scene of the crime. otherwise it’s hearsay and shillery -> -> Anonymous|11057: the fastest way to eliminate a suspect is to call him a suspect . . . we are all terrified of being unjust, but the pegs keep fitting in the holes . . . - -Many Anons remained uncomfortable with the idea of a dox. But around 7 A.M. a vote was taken. According to chat logs, of the eighty or so people in the I.R.C., fewer than ten participated. They decided to release Willman’s personal information. - -> Anonymous|2252: is this going on twitter? -> -> anondepp: lol -> -> Anonymous|2252: via @theanonmessage ? -> -> TheAnonMessage: yup -> -> TheAnonMessage: just did -> -> anondepp: its up -> -> Anonymous|2252: shit -> -> TheAnonMessage: Lord in heaven… -> -> Anonymous|3549: . . .have mercy on our souls -> -> anondepp: lol - -At 9:45 A.M., the St. Louis Police Department responded to TheAnonMessage. “Bryan Willman is not even an officer with Ferguson or St. Louis County PD,” the tweet read. “Do not release more info on this random citizen.” (The F.B.I. later opened an investigation into the hacking of police computers in Ferguson.) Twitter quickly suspended TheAnonMessage, but Willman’s name and address had been reported widely. - -Willman is the head police dispatcher in St. Ann, a suburb west of Ferguson. When the St. Louis Police Department’s Intelligence Unit called to tell him that he had been named as the killer, Willman told me, “I thought it was the weirdest joke.” Within hours, he received hundreds of death threats on his social-media accounts. He stayed in his house for nearly a week, alone, under police protection. “I just want it all to go away,” he told me. He thinks that Anonymous has irreparably harmed his reputation. “I don’t see how they can ever think they can be trusted again,” he said. - -“We are not perfect,” OpFerguson tweeted. “Anonymous makes mistakes, and we’ve made a few in the chaos of the past few days. For those, we apologize.” Though Doyon was not responsible for the errant dox attack, other Anons took the opportunity to shame him for having launched an operation that spiralled out of control. A Pastebin message, distributed by YourAnonNews, read, “You may notice contradictory tweets and information about #Ferguson and #OpFerguson from various Anonymous twitter accounts. Part of why there is dissension about this particular #op is that CommanderX is considered a ‘namefag/facefag’—a known entity who enjoys or at least doesn’t shun publicity—which is considered by most Anonymous to be bad form, for some probably fairly obvious reasons.” - -On his personal Twitter account, Doyon denied any involvement with Op Ferguson and wrote, “I hate this shit. I don’t want drama and I don’t want to fight with people I thought were friends.” Within a couple of days, he was sounding hopeful again. He recently retweeted messages reading, “You call them rioters, we call them voices of the oppressed” and “Free Tibet.” - -Doyon is still in hiding. Even Jay Leiderman, his attorney, does not know where he is. Leiderman says that, in addition to the charges in Santa Cruz, Doyon may face indictment for his role in the PayPal and Orlando attacks. If he is arrested and convicted on all counts, he could spend the rest of his life in prison. Following the example of Edward Snowden, he hopes to apply for asylum with the Russians. When we spoke, he used a lit cigarette to gesture around his apartment. “How is this better than a fucking jail cell? I never go out,” he said. “I will never speak with my family again. . . . It’s an incredibly high price to pay to do everything you can to keep people alive and free and informed.” - --------------------------------------------------------------------------------- - -via: http://www.newyorker.com/magazine/2014/09/08/masked-avengers - -作者：[David Kushner][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.newyorker.com/contributors/david-kushner diff --git a/sources/talk/20140911 5 Reasons Why I Hate GNU or Linux--Do You Hate (Love) Linux.md b/sources/talk/20140911 5 Reasons Why I Hate GNU or Linux--Do You Hate (Love) Linux.md deleted file mode 100644 index 29017fad07..0000000000 --- a/sources/talk/20140911 5 Reasons Why I Hate GNU or Linux--Do You Hate (Love) Linux.md +++ /dev/null @@ -1,100 +0,0 @@ -5 Reasons Why I Hate GNU/Linux – Do You Hate (Love) Linux? -================================================================================ -This part of Linux, I don’t like to talk very often but sometimes I do really feel some of the aspects related to Linux is real pain. Here are the five points which I come across on a daily basis, almost. - -![5 Reasons Why I Hate Linux](http://www.tecmint.com/wp-content/uploads/2014/09/I-Hate-Linux.jpg) - -5 Reasons Why I Hate Linux - -### 1. Choose from Too Many Good Distros ### - -While reading several on-line forum (a part of my hobby), I very often come across a question like – Hi, I am new to Linux, just [switched over from Windows to Linux][1]. Which Linux Distribution, I should get my hands dirty with? Oh! forgot to mention, I am an Engineering Student. - -As soon as someone posted such question, there is a flood of comments. each distribution’s fan boy tries to make sense that the distro he is using leads all the rest, a few comments may look like: - -1. Get your hands upon Linux Mint or Ubuntu, they are easy to use specially for newbies like you. -1. Ubuntu is Sh** better go with Mint. -1. If you want something like windows, better stay there. -1. Nothing is better than Debian. It is easy to use and contains all the packages you may need. -1. Slackware, for the point, if you learn slack you learn Linux. - At this point, the student who asked question really gets confused and annoyed. -1. CentOS – Nothing like this, when comes to stability. -1. I will recommend Fedora, Bleeding edge technology implementation, you will get a lot to learn. -1. Puppy Linux, SUSE, BSD, Manjaro, Megia, Kali, RedHat Beta, etc,…… - -At the end of discussion, the discussion forum may be used as a paper for research based upon the facts and figure provided in the comments. - -Now think the same in Windows or Mac – One may say are you Insane? Still using Windows XP or Vista but no one will try to prove that windows 8 is better than XP and XP is more on a User Friendly side. You won’t get a fan boy in Mac as well, who is trying to jump into the discussion just to make his point sounds louder. - -You may frequently come across points like – Distros are like religion. These things makes the newbie puzzled. Anyone who have used Linux for a considerable time would be knowing that all the distros are same at the base. It is only the working interface and the way to perform task differs and that too rarely. You are using apt, yum, portage, emerge, spike or ABS who cares as far as the things are done and user is comfortable with it. - -Well the above scenario is not only true in forums and groups on-line, it is sometimes taken to the corporate world. - -I was recently being Interviewed by a company based in Mumbai (India). The person interviewing, asked me several questions and technologies, I have worked with. As per their requirements, I have worked with nearly half of the technologies they were looking for. A few of last conversation as mentioned below. - -**Interviewer**: Do you know kernel editing? (Then he talked to himself for a couple of seconds – no, no not kernel editing, it is a very different thing.) Do you know how to compile a kernel on a monolithic side? - -**Me**: Yes, we just need to make sure what we need to run in future. We need to select those options only that supports our need before compiling the kernel. - -**Interviewer**: How do you compile a kernel? - -**Me**: make menuconfig, fire it as………..(interrupted) - -**Interviewer**: When have you compiled the kernel lastly without any help? - -**Me**: Very recently on my Debian…..(Interrupted) - -**Interviewer**: Debian? Do you know what we does? Debian-Febian is not of our use. We use CentOS. Ok, I will tell the management the result. They will call you. - -**Not to Mention**: I didn’t get the call or job, but certainly the phrase **Debian-febian** forces me to think over and over again. He could have said we don’t use Debian, we use CentOS. The tone of him, was a bit racist, it is spread-ed all over. - -### 2. Some of the very important software has no support in Linux ### - -No! I am not talking about Photoshop. I understand Linux is not build to perform such task. But some backbone softwares required to connect your Android phone to PC for Updation – PC Suite certainly means a lot. I have been looking for a windows PC. - -I know Linux is more like a server side OS. Really? Is not it trying to make a point that, it has been used as a Desktop as well? If Yes! It should have other developed desktop features. For a desktop user security, stability, RAID, Kernel does not mean much. They should get their work done with little or no effort. - -Moreover the companies like Samsung, Sony, Micromax, etc are dealing with Android (Linux) Phones and they have no support to get their phone connected over a Linux PC. - -Don’t drag me in PC suite discussion. For Linux to be a Desktop OS, it still lacks several things, Little or no gaming support – I mean high end gaming. No professional Video and Photo Editing Tools, I Said Professional. And yeah I remember Titanic and Avatar Movies were maid using some kind of FOSS video editor, I am coming to that point. - -Agree or not, Linux still has to go a long way to be a distro for everyone. - -### 3. Linuxer have a habit of living in virtual world ### - -I am a Linux user, and I am superior than you. I can handle terminal much better than you. You know Linux is Everywhere in your wrist watch, mobile phones, remote control. You know what, Hacker’s use Linux. Are you aware as soon as you boot Linux you become hacker. You can do several things from Linux you can’t even think of using Windows and Mac. - -Let me tell you, Linux is now being used in International Space Station. The world’s most successful movies Avatar and Titanic were build using Linux. Last but not the least, world’s 90% supercomputers are using Linux. World’s Top 5 fastest computer are using Linux. Facebook, Linkedin, Google, Yahoo all have their server based on Linux. - -I don’t mean they are wrong. I only mean they keeps on talking about the thing they very little know about. - -### 4. The long hours of compilation and dependency resolution ### - -I am aware of automatic dependency resolution and the program getting smart day by day. Still think from corporate view, I was installing a program say ‘y‘, it had one dependency say ‘**x**‘ which was unable to be resolved automatically. While resolving ‘**x**‘ I came across 8 other dependency, a few of other were dependent on a few other libraries and program. Isn’t it painful? - -The rule of corporate is to have the work done efficiently with less man power and as much less time as possible. Who cares if your piece of codes are coming from Windows or Mac or Linux as far as the work is done. - -### 5. Too much manual work ### - -No matter which distro you choose, you have to manually do a lot a things time-to-time. Lets say you are installing proprietary Nvidia Driver. Now you need to kill **X** manually, may need to edit **Xorg.conf** manually and still may have a broken **X**. Furthermore, you have to make sure that the next time kernel updates, it still be in working condition. - -Think of same on Windows. You have nothing to do other than firing the executables and click** Next, Next, I Agree, Next, Forward, Finish, Reboot** and your system may very rarely have broken GUI. Though the demerit is a broken GUI is not possible to be repaired on Windows but easily on Linux. - -Hey don’t tell me its because of security implementation.

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.

There are two levels of encryption to consider: SSL/TLS encryption protects your login and password to your mailserver. [GnuPG][1] is the standard strong Linux encryption tool, and it encrypts and authenticates your messages. It is best if you manage your own GPG encryption and not leave it up to third parties, which we will discuss in a moment. - -Encrypting messages still leaves you vulnerable to traffic analysis, as message headers must be in the clear. So that necessitates yet another tool such as the [Tor network][2] for hiding your Internet footprints. Let's look at various mail services and clients, and the pitfalls and benefits therein. - -### Forget Webmail ### - -If you use GMail, Yahoo, Hotmail, or another Web mail provider, forget about it. Anything you type in a Web browser is vulnerable to JavaScript attacks, and whatever mischiefs the service provider engages in. GMail, Yahoo, and Hotmail all offer SSL/TLS encryption to protect your messages from wiretapping. But they offer no protections from their own data-mining habits, so they don't offer end-to-end encryption. Yahoo and Google both claim they're going to roll out end-to-end encryption next year. Color me skeptical, because they will wither and die if anything interferes with the data-mining that is their core business. - -There are various third-party email security services such as [Virtru][3] and [SafeMess][4] that claim to offer secure encryption for all types of email. Again I am skeptical, because whoever holds your encryption keys has access to your messages, so you're still depending on trust rather than technology. - -Peer messaging avoids many of the pitfalls of using centralized services. [RetroShare][5] and [Bitmessage][6] are two popular examples of this. I don't know if they live up to their claims, but the concept certainly has merit. - -What about Android and iOS? It's safest to assume that the majority of Android and iOS apps are out to get you. Don't take my word for it-- read their terms of service and examine the permissions they require to install on your devices. And even if their terms are acceptable when you first install them, unilateral TOS changes are industry standard, so it is safest to assume the worst. - -### Zero Knowledge ### - -[Proton Mail][7] is a new email service that claims zero-knowledge message encryption. Authentication and message encryption are two separate steps, Proton is under Swiss privacy laws, and they do not log user activity. Zero knowledge encryption offers real security. This means that only you possess your encryption keys, and if you lose them your messages are not recoverable. - -There are many encrypted email services that claim to protect your privacy. Read the fine print carefully and look for red flags such as limited user data collection, sharing with partners, and cooperation with law enforcement. These indicate that they collect and share user data, and have access to your encryption keys and can read your messages. - -### Linux Mail Clients ### - -A standalone open source mail client such as KMail, Thunderbird, Mutt, Claws, Evolution, Sylpheed, or Alpine, set up with your own GnuPG keys that you control gives you the most protection. (The easiest way to set up more secure email and Web surfing is to run the TAILS live Linux distribution. See [Protect Yourself Online With Tor, TAILS, and Debian][8].) - -Whether you use TAILS or a standard Linux distro, managing GnuPG is the same, so let's learn how to encrypt messages with GnuPG. - -### How to Use GnuPG ### - -First, a quick bit of terminology. OpenPGP is an open email encryption and authentication protocol, based on Phil Zimmerman's Pretty Good Privacy (PGP). GNU Privacy Guard (GnuPG or GPG) is the GPL implementation of OpenPGP. GnuPG uses symmetric public key cryptography. This means that you create pairs of keys: a public key that anyone can use to encrypt messages to send to you, and a private key that only you possess to decrypt them. GnuPG performs two separate functions: digitally-signing messages to prove they came from you, and encrypting messages. Anyone can read your digitally-signed messages, but only people you have exchanged keys with can read your encrypted messages. Remember, never share your private keys! Only public keys. - -Seahorse is GNOME's graphical front-end to GnuPG, and KGpg is KDE's graphical GnuPG tool. - -Now let's run through the basic steps of creating and managing GnuPG keys. This command creates a new key: - - $ gpg --gen-key - -This is a multi-step process; just answer all the questions, and the defaults are fine for most people. When you create your passphrase, write it down and keep it in a secure place because if you lose it you cannot decrypt anything. All that advice about never writing down your passwords is wrong. Most of us have dozens of logins and passwords to track, including some that we rarely use, so it's not realistic to remember all of them. You know what happens when people don't write down their passwords? They create simple passwords and re-use them. Anything you store on your computer is potentially vulnerable; a nice little notebook kept in a locked drawer is impervious to everything but a physical intrusion, if an intruder even knew to look for it. - -I must leave it as your homework to figure out how to configure your mail client to use your new key, as every one is different. You can list your key or keys: - - $ gpg --list-keys - /home/carla/.gnupg/pubring.gpg - ------------------------------ - pub 2048R/587DD0F5 2014-08-13 - uid Carla Schroder (my gpg key) - sub 2048R/AE05E1E4 2014-08-13 - -This is a fast way to grab necessary information like the location of your keys, and your key name, which is the UID. Suppose you want to upload your public key to a keyserver; this is how it looks using my example key: - - $ gpg --send-keys 'Carla Schroder' --keyserver http://example.com - -When you create a new key for upload to public key servers, you should also create a revocation certificate. Don't do it later-- create it when you create your new key. You can give it any arbitrary name, so instead of revoke.asc you could give it a descriptive name like mycodeproject.asc: - - $ gpg --output revoke.asc --gen-revoke 'Carla Schroder' - -Now if your key ever becomes compromised you can revoke it by first importing the revocation certificate into your keyring: - - $ gpg --import ~/.gnupg/revoke.asc - -Then create and upload a new key to replace it.

For example, you may be testing experimental features of a web server. Or you may be debugging a web application or a RESTful service. Or you may be trying to troubleshoot [PAC (proxy auto config)][1] or check for any malware files surreptitiously downloaded from a website. Whatever the reason is, there are cases where HTTP traffic sniffing is helpful, for system admins, developers, or even end users. - -While [packet sniffing tools][2] such as tcpdump are popularly used for live packet dump, you need to set up proper filtering to capture HTTP traffic, and even then, their raw output typically cannot be interpreted on the HTTP protocol level so easily. Real-time web server log parsers such as [ngxtop][3] provide human-readable real-time web traffic traces, but only applicable with a full access to live web server logs. - -What will be nice is to have tcpdump-like traffic sniffing tool, but targeting HTTP traffic only. In fact, [httpry][4] is extactly that: **HTTP packet sniffing tool**. httpry captures live HTTP packets on the wire, and displays their content at the HTTP protocol level in a human-readable format. In this tutorial, let's see how we can sniff HTTP traffic with httpry. - -### Install httpry on Linux ### - -On Debian-based systems (Ubuntu or Linux Mint), httpry is not available in base repositories. So build it from the source: - - $ sudo apt-get install gcc make git libpcap0.8-dev - $ git clone https://github.com/jbittel/httpry.git - $ cd httpry - $ make - $ sudo make install - -On Fedora, CentOS or RHEL, you can install httpry with yum as follows. On CentOS/RHEL, enable [EPEL repo][5] before running yum. - - $ sudo yum install httpry - -If you still want to build httpry from the source, you can easily do that by: - - $ sudo yum install gcc make git libpcap-devel - $ git clone https://github.com/jbittel/httpry.git - $ cd httpry - $ make - $ sudo make install - -### Basic Usage of httpry ### - -The basic use case of httpry is as follows. - - $ sudo httpry -i - -httpry then listens on a specified network interface, and displays captured HTTP requests/responses in real time. - -![](https://farm4.staticflickr.com/3883/14985851635_7b94787c6d_z.jpg) - -In most cases, however, you will be swamped with the fast scrolling output as packets are coming in and out. So you want to save captured HTTP packets for offline analysis. For that, use either '-b' or '-o' options. The '-b' option allows you to save raw HTTP packets into a binary file as is, which then can be replayed with httpry later. On the other hand, '-o' option saves human-readable output of httpry into a text file. - -To save raw HTTP packets into a binary file: - - $ sudo httpry -i eth0 -b output.dump - -To replay saved HTTP packets: - - $ httpry -r output.dump - -Note that when you read a dump file with '-r' option, you don't need root privilege. - -To save httpr's output to a text file: - - $ sudo httpry -i eth0 -o output.txt - -### Advanced Usage of httpry ### - -If you want to monitor only specific HTTP methods (e.g., GET, POST, PUT, HEAD, CONNECT, etc), use '-m' option: - - $ sudo httpry -i eth0 -m get,head - -![](https://farm6.staticflickr.com/5551/14799184220_3b449d422c_z.jpg) - -If you downloaded httpry's source code, you will notice that the source code comes with a collection of Perl scripts which aid in analyzing httpry's output. These scripts are found in httpry/scripts/plugins directory. If you want to write a custom parser for httpry's output, these scripts can be good examples to start from. Some of their capabilities are: - -- **hostnames**: Displays a list of unique host names with counts. -- **find_proxies**: Detect web proxies. -- **search_terms**: Find and count search terms entered in search services. -- **content_analysis**: Find URIs which contain specific keywords. -- **xml_output**: Convert output into XML format. -- **log_summary**: Generate a summary of log. -- **db_dump**: Dump log file data into a database. - -Before using these scripts, first run httpry with '-o' option for some time. Once you obtained the output file, run the scripts on it at once by using this command: - - $ cd httpry/scripts - $ perl parse_log.pl -d ./plugins - -You may encounter warnings with several plugins. For example, db_dump plugin may fail if you haven't set up a MySQL database with DBI interface. If a plugin fails to initialize, it will automatically be disabled. So you can ignore those warnings. - -After parse_log.pl is completed, you will see a number of analysis results (*.txt/xml) in httpry/scripts directory. For example, log_summary.txt looks like the following. - -![](https://farm4.staticflickr.com/3845/14799162189_b85abdf21d_z.jpg) - -To conclude, httpry can be a life saver if you are in a situation where you need to interpret live HTTP packets. That might not be so common for average Linux users, but it never hurts to be prepared.

Depending on how data is stored in an array of disks (e.g., with striping, mirroring, parity, or any combination thereof), different RAID levels are defined (e.g., RAID-0, RAID-1, RAID-5, etc). RAID can be implemented either in software or with a hardware RAID card. On modern Linux, basic software RAID functionality is available by default. + +In this post, we'll discuss the software setup of a RAID-1 array (also known as a "mirroring" array), where identical data is written to the two devices that form the array. While it is possible to implement RAID-1 with partitions on a single physical hard drive (as with other RAID levels), it won't be of much use if that single hard drive fails. In fact, that's why most RAID levels normally use multiple physical drives to provide redundancy. In the event of any single drive failure, the virtual RAID block device should continue functioning without issues, and allow us to replace the faulty drive without significant production downtime and, more importantly, with no data loss. However, it does not replace the need to save periodic system backups in external storage. + +Since the actual storage capacity (size) of a RAID-1 array is the size of the smallest drive, normally (if not always) you will find two identical physical drives in RAID-1 setup. + +### Installing mdadm on Linux ### + +The tool that we are going to use to create, assemble, manage, and monitor our software RAID-1 is called mdadm (short for **m**ultiple **d**isks **adm**in). On Linux distros such as Fedora, CentOS, RHEL or Arch Linux, mdadm is available by default. On Debian-based distros, mdadm can be installed with aptitude or apt-get. + +#### Fedora, CentOS or RHEL #### + +As mdadm comes pre-installed, all you have to do is to start RAID monitoring service, and configure it to auto-start upon boot: + + # systemctl start mdmonitor + # systemctl enable mdmonitor + +For CentOS/RHEL 6, use these commands instead: + + # service mdmonitor start + # chkconfig mdmonitor on + +#### Debian, Ubuntu or Linux Mint #### + +On Debian and its derivatives, mdadm can be installed with **aptitude or apt-get**: + + # aptitude install mdadm + +On Ubuntu, you will be asked to configure postfix MTA for sending out email notifications (as part of RAID monitoring). You can skip it for now. + +On Debian, the installation will start with the following explanatory message to help us decide whether or not we are going to install the root filesystem on a RAID array. What we need to enter on the next screen will depend on this decision. Read it carefully: + +![](https://farm4.staticflickr.com/3918/15220883382_c14eb95914_z.jpg) + +Since we will not use our RAID-1 for the root filesystem, we will leave the answer blank: + +![](https://farm6.staticflickr.com/5555/15198241896_29e08b977f.jpg) + +When asked whether we want to start (reassemble) our array automatically during each boot, choose "Yes". Note that we will need to add an entry to the /etc/fstab file later in order for the array to be properly mounted during the boot process as well. + +![](https://farm4.staticflickr.com/3875/15220883342_2b1d689a0a_z.jpg) + +### Partitioning Hard Drives ### + +Now it's time to prepare the physical devices that will be used in our array. For this setup, I have plugged in two 8 GB USB drives that have been identified as /dev/sdb and /dev/sdc from dmesg output: + + # dmesg | less + +---------- + +[ 60.014863] sd 3:0:0:0: [sdb] 15826944 512-byte logical blocks: (8.10 GB/7.54 GiB) +[ 75.066466] sd 4:0:0:0: [sdc] 15826944 512-byte logical blocks: (8.10 GB/7.54 GiB) + +We will use fdisk to create a primary partition on each disk that will occupy its entire size. The following steps show how to perform this task on /dev/sdb, and assume that this drive hasn't been partitioned yet (otherwise, we can delete the existing partition(s) to start off with a clean disk): + + # fdisk /dev/sdb + +Press 'p' to print the current partition table: + +![](https://farm4.staticflickr.com/3883/15198241836_24625edcf3_z.jpg) + +(if one or more partitions are found, they can be deleted with 'd' option. Then 'w' option is used to apply the changes). + +Since no partitions are found, we will create a new primary partition ['n'] as a primary partition ['p'], assign the partition number = ['1'] to it, and then indicate its size. You can press Enter key to accept the proposed default values, or enter a value of your choosing, as shown in the image below. + +![](https://farm4.staticflickr.com/3875/15034475369_7e72fb9f2e_z.jpg) + +Now repeat the same process for /dev/sdc. + +If we have two drives of different sizes, say 750 GB and 1 TB for example, we should create a primary partition of 750 GB on each of them, and use the remaining space on the bigger drive for another purpose, independent of the RAID array. + +### Create a RAID-1 Array ### + +Once you are done with creating the primary partition on each drive, use the following command to create a RAID-1 array: + + # mdadm -Cv /dev/md0 -l1 -n2 /dev/sdb1 /dev/sdc1 + +Where: + +- **-Cv**: creates an array and produce verbose output. +- **/dev/md0**: is the name of the array. +- **-l1** (l as in "level"): indicates that this will be a RAID-1 array. +- **-n2**: indicates that we will add two partitions to the array, namely /dev/sdb1 and /dev/sdc1. + +The above command is equivalent to: + + # mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1 + +If alternatively you want to add a spare device in order to replace a faulty disk in the future, you can add '--spare-devices=1 /dev/sdd1' to the above command. + +Answer "y" when prompted if you want to continue creating an array, then press Enter: + +![](https://farm4.staticflickr.com/3894/15034569970_709bd51718.jpg) + +You can check the progress with the following command: + + # cat /proc/mdstat + +![](https://farm6.staticflickr.com/5565/15221267975_701b819e6d_z.jpg) + +Another way to obtain more information about a RAID array (both while it's being assembled and after the process is finished) is: + + # mdadm --query /dev/md0 + # mdadm --detail /dev/md0 (or mdadm -D /dev/md0) + +![](https://farm6.staticflickr.com/5583/15034683868_6c28564e5a_z.jpg) + +Of the information provided by 'mdadm -D', perhaps the most useful is that which shows the state of the array. The active state means that there is currently I/O activity happening. Other possible states are clean (all I/O activity has been completed), degraded (one of the devices is faulty or missing), resyncing (the system is recovering from an unclean shutdown such as a power outage), or recovering (a new drive has been added to the array, and data is being copied from the other drive onto it), to name the most common states. + +### Formatting and Mounting a RAID Array ### + +The next step is formatting (with ext4 in this example) the array: + + # mkfs.ext4 /dev/md0 + +![](https://farm4.staticflickr.com/3849/15034683838_01e34e7196_z.jpg) + +Now let's mount the array, and verify that it was mounted correctly: + + # mount /dev/md0 /mnt + # mount + +![](https://farm6.staticflickr.com/5554/15034696167_c4fc907c8e_z.jpg) + +### Monitor a RAID Array ### + +The mdadm tool comes with RAID monitoring capability built in. When mdadm is set to run as a daemon (which is the case with our RAID setup), it periodically polls existing RAID arrays, and reports on any detected events via email notification or syslog logging. Optionally, it can also be configured to invoke contingency commands (e.g., retrying or removing a disk) upon detecting any critical errors. + +By default, mdadm scans all existing partitions and MD arrays, and logs any detected event to /var/log/syslog. Alternatively, you can specify devices and RAID arrays to scan in mdadm.conf located in /etc/mdadm/mdadm.conf (Debian-based) or /etc/mdadm.conf (Red Hat-based), in the following format. If mdadm.conf does not exist, create one. + + DEVICE /dev/sd[bcde]1 /dev/sd[ab]1 + + ARRAY /dev/md0 devices=/dev/sdb1,/dev/sdc1 + ARRAY /dev/md1 devices=/dev/sdd1,/dev/sde1 + ..... + + # optional email address to notify events + MAILADDR your@email.com + +After modifying mdadm configuration, restart mdadm daemon: + +On Debian, Ubuntu or Linux Mint: + + # service mdadm restart + +On Fedora, CentOS/RHEL 7: + + # systemctl restart mdmonitor + +On CentOS/RHEL 6: + + # service mdmonitor restart + +### Auto-mount a RAID Array ### + +Now we will add an entry in the /etc/fstab to mount the array in /mnt automatically during boot (you can specify any other mount point): + + # echo "/dev/md0 /mnt ext4 defaults 0 2" << /etc/fstab + +To verify that mount works okay, we now unmount the array, restart mdadm, and remount. We can see that /dev/md0 has been mounted as per the entry we just added to /etc/fstab: + + # umount /mnt + # service mdadm restart (on Debian, Ubuntu or Linux Mint) + or systemctl restart mdmonitor (on Fedora, CentOS/RHEL7) + or service mdmonitor restart (on CentOS/RHEL6) + # mount -a + +![](https://farm6.staticflickr.com/5563/15218183681_63a10da704_z.jpg) + +Now we are ready to access the RAID array via /mnt mount point. To test the array, we'll copy the /etc/passwd file (any other file will do) into /mnt: + +![](https://farm6.staticflickr.com/5593/15034475219_a3476aec0a_o.png) + +On Debian, we need to tell the mdadm daemon to automatically start the RAID array during boot by setting the AUTOSTART variable to true in the /etc/default/mdadm file: + + AUTOSTART=true + +### Simulating Drive Failures ### + +We will simulate a faulty drive and remove it with the following commands. Note that in a real life scenario, it is not necessary to mark a device as faulty first, as it will already be in that state in case of a failure. + +First, unmount the array: + + # umount /mnt + +Now, notice how the output of 'mdadm -D /dev/md0' indicates the changes after performing each command below. + + # mdadm /dev/md0 --fail /dev/sdb1 #Marks /dev/sdb1 as faulty + # mdadm --remove /dev/md0 /dev/sdb1 #Removes /dev/sdb1 from the array + +Afterwards, when you have a new drive for replacement, re-add the drive again: + + # mdadm /dev/md0 --add /dev/sdb1 + +The data is then immediately started to be rebuilt onto /dev/sdb1: + +![](https://farm4.staticflickr.com/3855/15221267875_dfc6af8804_z.jpg) + +Note that the steps detailed above apply for systems with hot-swappable disks. If you do not have such technology, you will also have to stop a current array, and shutdown your system first in order to replace the part: + + # mdadm --stop /dev/md0 + # shutdown -h now + +Then add the new drive and re-assemble the array: + + # mdadm /dev/md0 --add /dev/sdb1 + # mdadm --assemble /dev/md0 /dev/sdb1 /dev/sdc1 + +Hope this helps. + +-------------------------------------------------------------------------------- + +via: http://xmodulo.com/2014/09/create-software-raid1-array-mdadm-linux.html + +作者：[Gabriel Cánepa][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://xmodulo.com/author/gabriel diff --git a/sources/tech/20140924 Unix----stat -- more than ls.md b/sources/tech/20140924 Unix----stat -- more than ls.md new file mode 100644 index 0000000000..f2c5abf45b --- /dev/null +++ b/sources/tech/20140924 Unix----stat -- more than ls.md @@ -0,0 +1,124 @@ +wangjiezhe translating + +Unix: stat -- more than ls +================================================================================ +> Tired of ls and want to see more interesting information on your files?

Is there a way to build and install a package from the source, instead of running "make install"? That way, I could uninstall the program easily later if I want to. + +If you have installed a Linux program from its source by running "make install", it becomes really tricky to remove it completely, unless the author of the program provides an uninstall target in the Makefile. You will have to compare the complete list of files in your system before and after installing the program from source, and manually remove all the files that were added during the installation. + +That is when CheckInstall can come in handy. CheckInstall keeps track of all the files created or modified by an install command line (e.g., "make install" "make install_modules", etc.), and builds a standard binary package, giving you the ability to install or uninstall it with your distribution's standard package management system (e.g., yum for Red Hat or apt-get for Debian). It has been also known to work with Slackware, SuSe, Mandrake and Gentoo as well, as per the [official documentation][1]. + +In this post, we will only focus on Red Hat and Debian based distributions, and show how to build a RPM or DEB package from the source using CheckInstall. + +### Installing CheckInstall on Linux ### + +To install CheckInstall on Debian derivatives: + + # aptitude install checkinstall + +To install CheckInstall on Red Hat-based distributions, you will need to download a pre-built .rpm of CheckInstall (e.g., searchable from [http://rpm.pbone.net][2]), as it has been removed from the Repoforge repository.

In general, how can I catch and handle various signals (e.g., INT, TERM) in a Perl program? + +As an asynchronous notification mechanism in the POSIX standard, a signal is sent by an operating system to a process to notify it of a certain event. When a signal is generated, the target process's execution is interrupted by an operating system, and the signal is delivered to the process's signal handler routine. One can define and register a custom signal handler or rely on the default signal handler. + +In Perl, signals can be caught and handled by using a global %SIG hash variable.

What is a proper way to rename a network interface on CentOS or RHEL 7? + +Traditionally, network interfaces in Linux are enumerated as eth[0123...], but these names do not necessarily correspond to actual hardware slots, PCI geography, USB port number, etc. This introduces a unpredictable naming problem (e.g., due to undeterministic device probing behavior) which can cause various network misconfigurations (e.g., disabled interface or firewall bypass resulting from unintentional interface renaming). MAC address based udev rules are not so much helpful in a virtualized environment where MAC addresses are as euphemeral as port numbers. + +CentOS/RHEL 6 has introduced a method for [consistent and predictable network device naming][1] for network interfaces.

However, this naming rule is not turned on by default on CentOS/RHEL 6. + +Starting with CentOS/RHEL 7, the predictable naming rule is adopted by default.

+这样说吧：IDE只是构建和测试你的应用的地方，托管服务器才是它们生存的地方。所以一旦完成了你的应用，你会希望把它布置到能长期托管的云服务器上，最好是能免费托管的那种，例如[Heroku][6]。 + +### 选择一个IDE ### +

+“大多数IDE服务的协同功能只能操作单一文件”，Daniels说，“而我们的产品可以支持整个项目中的不同文件。协同功能被完美集成到了我们的IDE中。” + +### Koding：在你需要的时候能提供帮助 ### + +IDE可以提供你所需的工具来构建和测试所有开源编程语言的应用。对于初学者来说，看起来有点吓人。举个例子，如果我要做一个项目同时用到Python和Ruby组件，那我要用哪个VM来测试？ + +答案是两个都要，尽管使用免费账号的话，只能够同时打开一个VM用于测试。我就在Koding的控制面板里找到了答案，一个折叠起来的地方，用户可以提供或获得他们Koding项目的各种经验。在这三者中间，它是最容易使用的，拥有一个你可以寻求帮助并很快有人回答的地方。 + +“我们在这款产品里加入了一个积极的社区功能”，Koding的首席商务官Nitin Gupta说，“我们希望搭建一个环境，真正吸引那些希望得到帮助和愿意提供帮助的人们。” + +### Nitrous.IO: An IDE Wherever You Want ### + +相对于自己的桌面环境，使用IDE的最大优势是它是自包含的。你不需要安装任何其他的就可以使用。而另一方面，使用自己的桌面环境的最大优势就是你可以在本地工作，甚至在没有互联网的情况下。 + +Nitrous.IO结合了这两个优势。你可以在网站上在线使用这个IDE，你也可以把它下载到自己的饿电脑上，共同创始人AJ Solimine这样说。优点是你可以结合Nitrous的集成性和你最喜欢的文字编辑器的熟悉。 + +他说：“你可以使用任意当代浏览器访问Nitrous.IO的在线IDE网站，但我们仍然提供了方便的Windows和Mac桌面应用，可以让你使用你最喜欢的编辑器来写代码。” + +### 底线 ### + +这一个星期的[使用][7]三个不同IDE的最让我意外的收获？它们是如此相似。[当用来做最基本的代码编辑的时候][8]，它们都一样的好用。 + +Cloud9，Koding，[和Nitrous.IO都支持][9]所有主流的开源编程语言，从Ruby到Python到PHP到HTML5。你可以选择任何一种VM。 + +Cloud9和Nitrous.IO都实现了GitHub的一键集成。Koding需要[多几个步骤][10]，不过也是可以实现的。 + +每一个都轻松地集成了我需要的API。每一个也都可以让我自己安装喜欢的包（Koding需要超级用户权限）。它们都带有内置的终端，可以用来轻松地测试和布置项目。三个都支持轻松地预览项目。当然，它们也都把我的项目托管在云服务器中，所以我在任意地方都可以在上边工作。 + +不好的一面，它们都有相同的缺陷，不过考虑到它们都是免费的也还合理。你每次只能同时运行一个VM来测试特定编程语言写出的程序。而当你一段时间没有使用VM之后，IDE会把VM切换成休眠模式以节省带宽，而下次要用的时候就得等它重新加载（Cloud9在这一点上更加费力）。它们中也没有任何一个为已完成的项目提供像样的永久托管服务。 + +所以，对咨询我是否有一个完美的免费IDE的人，答案是可能没有。但是这也要看你侧重的地方，对你的某个项目来说也许有一个完美的IDE。 + +图片由[Shutterstock][11]友情提供 + +-------------------------------------------------------------------------------- + +via:

Raymond写道][2]，全世界95%的软件写来用的，而不是售卖。原因很多，但是其中有一个比较突出：正如Zulily的CIO Luke Friang所说，几乎没有一个[非定制]软件解决方案能跟上我们的步伐。 + +20年前是这样，现在也是这样。 + +但是有一点是不同的，这也正是华尔街日报完全忽略的地方。而这也正是历史上开发的内部软件始终保持着专有的原因了，因为她是一个公司的 核心竞争力。然而今天，越来越多的公司意识到另一面：开源内部软件将会比保持专有获益更多。 + +这也就是为什么你的公司需要为开源项目做出更多的贡献。记住是更多。 + +我们刚刚经历了一个很不一样的20年，那时很多软件的开发都是为了内部的使用，大多数人的精力都放在由SAP和微软这样的厂商建立的应用广泛的企业级解决方案。 + +不管怎么说，这都是一个理论。 + +在实践中，买方花费很少的钱购买license，然后至少付出5倍以上的代价来使软件符合他们的需求。比如说，一个公司可能在一个ERP系统上花费 100,000美元，但是他们还得继续花费500,000来维持软件正常运行。 + +开源软件甚至是应用程序正式发展起来的原因之一是很多公司可以免费获得一些功能性的产品（或者是以一个相对便宜的费用获得产品）， 然后定制为他们所需要的。不管怎样，定制是有必要的，而且开源的根本是使成本更低，或许，这样的定制或许能产生更好的结果。 + +同时，开发者尽量的减少同类之间的相似之处。作为Redmonk分析师，[Stephen O'Grady认为][3]: + +> 从最近几年看，主流技术产业都有意避开专业化。运行在定制操作系统上的虚拟设备，已经彻底败给了RHEL和Windowns这些通用的操作系统。 最快20年，任何程序的数据保存都意味着一件事：一个关联的数据库，如果你要做的是企业级应用开发，那么你首先要接触的是Java，等等。 + +然而，开源的道路上，一些公司也发现，有些销售商不能很好地描述他们所想要的，即便是很好理解的产品类别，如像内容管理系统，他们需要 知道的是产品亮点，而不希望是一个模子刻出来的。 + +所以顾客没了，他们中有一部分上转变变成了供应商。 + +这也是常有的事，[O'Grady指出了][4]这一点。2010年，O'Grady发现了一个有趣的现象：“软件提供商正面对着一个强有力的市场竞争者：他们 的顾客。” + +回想一下今天的高科技，大多数都是开源的，几乎所有的项目一开始都是某些公司的内部项目，或者仅仅是有些开发者的爱好，Linux，Git，Hadoop，Cassandra，MongDB，Android，等等。没有一个项目起初是为了售卖而产生的。 + +相反，这些项目通常是由一些公司维护，他们使用开源的资源来构建软件并[完善软件][5]，这主要是一些Web公司。不像以前银行，医院和一些组织开发的软件只供内部使用，他们开源源码。 + +虽然，[有些公司避免定制软件][6]，因为他们不想自己维护它，开源(稍微)减轻了这些发展中公司来维护一个项目的压力。从而为项目发起人均摊项目的开发成本，Yahoo，开始于Hadoop，但是现在最大的贡献者是Cloudera和Hortonworks。Facebook开始于Cassandra，但是现在主要是靠DataStax在维护。等等。 + +今天，真正的软件创新并不是闭门造车能造出来的，即便是可以，它也不会在那儿，开源项目颠覆了几十年的软件开发传统。 + +这不仅仅是一个人的一点点力量。 + +最好的开源项目都[发展得很快][7]，但是这并不意味着别人在乎你的开源代码。[开放你的源码有显著的优缺点][8]，其中一个很重要的优点是 很多伟大的开发者都希望为开源做出贡献：如果你也想找一个伟大的开发者跟你一起，你需要给他们一个开放的源代码来让他们工作。（[Netflix][9]说） + +但是，我们没有理由站在一边看，现在正是时候参与开源社区了，而不是一些不清楚的社区。是的，开源最大的参与者正是你们和你们的公司。 赶紧开始吧。 + +主要图片来自于Shutterstock.

-好消息是，像华为这样的公司就把开源作为一种战略前景。具体而言，当华为的开源项目过时或者不是很强势的时候，这种现象就证明了他们的科技步伐是错误的。在与参与了开源项目的华为公司内部顾问的谈话中，虽然华为对如何参与到开源社区还处于摸索阶段，但他们总是对华为的开源项目赞不绝口。 - -这种无人关注开源的现象不会长久地持续下去。 - -从一件事就可以看出端倪。中国最大的互联网公司们都纷纷以积极地姿态拥抱开源，这意味着中国开源时代的到来。你若是和任意一位在百度、阿里巴巴、微博的员工谈话，你会发现他们的软件项目都是彻底开源的。这些开源的软件都是运行在这些公司自己研发的硬件上而不是西方的硬件上。 - -换句话说，这样的模式已经和西方的运营模式如出一辙了。 - -抬头看看 [现金软件行业内最炙手可热的新公司][5]， 你就会知道中国的互联网公司未来的主流趋势，正如发生在西方世界的一样。不出意料的，许多都是关于“开源”。 - -### 销售给中国 ### - -所有的一切都表明中国的软件行业不会像美国的软件行业发展历史一般发展。中国不会产生在柜台上卖卖软件就赚上亿美元的公司。因为西方对于知识产权的观念就是不适于中国的科技经济。 - -所以，软件卖家们需要售卖币软件更丰富的产品。云服务是一大前景。硬件设施看起来也是前途璀璨。软件支持和咨询服务（虽然有一些非主流）也很被公司门看好。总而言之，中国的软件行业会充满了开源味道，而不能靠着简单的售卖专柜软件的形式赚钱。 - -图片由 [hackNY.org][6] 提供。 -

+![](http://thevarguy.com/site-files/thevarguy.com/files/imagecache/medium_img/uploads/2014/08/linus-torvalds-1.jpg) + +什么是Linux桌面和嵌入式设备中Linux的未来？这是个值得讨论的问题，不过Linux的创始人和开源巨人Linus Torvalds在最近一届 [Linux 基金会][1] 的LinuxCon大会上，在一次对话中表达了一些有趣的观点。 + +作为敲出第一版Linux内核代码并且在1991年将它们共享在互联网上的家伙，Torvalds毫无疑问是开源软件甚至是任何软件中最著名的开发者，如今他依然活跃在其中。在此期间，Torvalds是许多人和组织中唯一一个引领着Linux发展的个体，它的观点往往能影响着开源社区，而且，作为一个内核开发者的角色赋予了他能决定哪些特点和代码能被放进操作系统内部的强大权利。 + +所以说，关注Torvalds所说的话是很值得的， "我还是挺想要桌面的。" [上周他在LinuxCon大会上这样说道][2] 那标志着他仍然着眼于作为使个人机更加强大的操作系统Linux的未来，尽管十年来Linux桌面市场的分享一直很少，而且大部分围绕Linux的商业活动都去涉及服务器或者安卓手机硬件去了。 + +但是，Torvalds还说，确保Linux桌面能有个宏伟的未来意味着解决了受阻的 “基础设施问题”，好像庞大的开源软件生态系统和硬件世界让他充满信心。这不是Linux核心代码本身的问题，而是要让Linux桌面渠道友好，这可能是伟大的Torvalds和他开发同伴们所需要花精力去达到的目标。这取决于app的开发者、硬件制造商和其它有志于实现人们能方便使用基于Linux的计算平台的各方力量。 + +另一方面，Torvalds也提到了他的憧憬，就是内核开发者们能简化嵌入式装置中的Linux代码——一个在让内核更加桌面友好化上会导致很多分歧的任务。但这也不一定，因为无论如何，Linux都是以模块化设计的，单内核代码库不能同时满足桌面用户和嵌入式开发者的需求，这是没有道理的，因为这取决于他们使用的模块。 + +作为一个长时间想看到更多搭载Linux的嵌入式设备出现的Linux桌面用户，我希望Torvalds的所有愿望都可以实现，到那时我就能只用Liunx来做所有我想做的事情，无论是在电脑桌面上、手机上、车上，或者是任何其它的地方。 + +-------------------------------------------------------------------------------- +

23岁生日，就让我们告诉你**一些你可能不知道的linux趣事和linux历史**。如果有什么要补充的，请在评论中分享出来。在这篇文章里，我可能用会用“linux”，“kernel”和“Linux kernel”来表示同一个意思。 + +1.关于linux是否是一个开源的操作系统这种争论一直是无休无止的。事实上，“Linux”操作系统的核心组件参照的是Linux kernel（内核）。而反派认为Linux不是一个纯粹的操作系统，因为他们认为仅仅一个内核（kernel），并不是一个操作系统，自由软件的推崇者认为最大的操作系统应叫做“[GNU/Linux][7]”把功劳归于应得的人。（比如：[GNU project][8]）。另一方面，一些linux的开发者认为，linux拥有成为一个操作系统的资格，因为它实现了[POSIX标准][9]。 + +2.从openhub网站的统计来看，绝大部分（95%）的Linux是用C语言写的。第二（2.8%）受欢迎的是汇编语言。毫无疑问，C语言比C++ 的更受欢迎，也表明了linus对C++的立场。下面是Linus编程语言的分类。 + +![](https://farm4.staticflickr.com/3845/15025332121_055cfe3a2c_z.jpg) + +3.在世界上，Linux已经被[13,036个贡献者][10]创建和修改。当然，贡献最多的还是Linus Torvalds自己。直到目前，他提交了20,000次以上的代码。下图显示了所有提交次数最多的前十位Linux贡献者。 + +![](https://farm4.staticflickr.com/3837/14841786838_7a50625f9d_b.jpg) + +4.Linux的代码行（SLOC）有超过1700万行。估计整个代码库的花费大概是5,526人年，或者是超过300M（1M=10*1000万亿）美元，[基于模型的基本估算法][11]（basic COCOMO model）。 + +5.企业并不是单纯的Linux消费者。他们的员工也在[积极参与][12]Linux的开发。下图显示了前十的Linux内核开发参与的企业员工2013年提交次数的总和。他们包括linux的商业版发行者(Red Hat,SUSE),芯片/嵌入式系统制造商（Intel，Texas

+6.Linux的官方吉祥物是“小企鹅”，一个非常可爱的企鹅标志。[第一次提出][13]并决定小企鹅作为Linux吉祥物/标志这个想法的是Linus自己。为什么是小企鹅呢？因为Linus本人很喜欢企鹅，尽管他曾经被一只凶猛的企鹅咬伤过，还导致他得了一场病。 + +7.一个Linux系统“包括”Linux内核、支持GUN的组件和库、和一些第三方的应用。[distrowatch网站][14]显示，现在总共有286个活跃的Linux发行版。其中最老的一个版本叫[Slackware][15],它是从1993年正式发布出来的一个可用的版本。 + +8.Kernel.org是一个Linux源码的主要仓库，曾经在2011年8月被一个匿名的攻击者[攻陷][16],攻击者打算篡改kernel.org的服务器。为了加强linux内核的访问策略的安全性，Linux基金会最近在Linux内核的Git官方托管的仓库上[开启了][17]双重认证。 + +9.Linux在500强超级计算机中的优势还在[增加][18]。截至2014年6月，运算速度最快的计算机97%都是运行在Linux上面的。 + +10.太空监视（spacewatch），是亚利桑那大学月球与行星实验室的一个研究项目，在GNU/Linux和它的创造者们出现之后，用他们名字命名了几颗小行星（[小行星9793 Torvalds][19],[小行星9882 Stallman][20]，[小行星9885 Linux][21]，[小行星9965 GUN][22]），以表彰他们把开源操作系统用于他们的小行星调查活动。 + +11.纵观Linux内核发展得近代史，版本从2.6到3.0有一个很大的跳跃。这个[重编的版本号3][23]实际上并不是意味着Linux内核有什么重大的构建，但却标志着Linux 20周年的一个里程碑。 + +12.在2000年的时候，乔帮主还在苹果。他当时就[尝试雇佣][24]Linus Torvalds，让他放弃Linux的开发，转而为“Unix最大的用户群工作”，这个项目后面发展成了MAC OS X。当时，linus拒绝了乔帮主的邀请。 + +13.Linux 内核的重启函数[reboot()][25]要求两个神奇的数字，而这第二个数字来自Linus Torvalds和他的3个女儿的出生日期。 + +14.虽然全世界都有Linux的很多粉丝，但是也仍然存在很多对Linux的批评（主要是桌面系统），如缺乏硬件支持，缺乏标准化，由于很短的升级和发布周期导致系统的不稳定，等。2014年Linux内核小组在linuxCon大会上，当Linus被问及Linux的未来将何去何从，他表示“I still want the desktop”(我仍然希望桌面化)。 +

通过入会声明，任何人都能轻易加入“匿名者”组织。某人类学家称，组织成员会“根据影响程度对重大事件保持着不同关注，特别是那些能挑起强烈争端的事件”。

上世纪七十年代中期，当 Christopher Doyon 还是一个生活在缅因州乡村的孩童时，就终日泡在 CB radio 上与各种陌生人聊天。他的昵称是“大红”，因为他有一头红色的头发。Christopher Doyon 把发射机挂在了卧室的墙壁上，并且说服了父亲在自家屋顶安装了两根天线。CB radio 主要用于卡车司机间的联络，但 Doyon 和一些人却将之用于不久后出现在 Internet 上的虚拟社交——自定义昵称、成员间才懂的笑话，以及施行变革的强烈愿望。

+ +

Doyon 很小的时候母亲就去世了，兄妹二人由父亲抚养长大，他俩都说受到过父亲的虐待。由此 Doyon 在 CB radio 社区中找到了慰藉和归属感。他和他的朋友们轮流监听当地紧急事件频道。其中一个朋友的父亲买了一个气泡灯并安装在了他的车顶上；每当这个孩子收听到来自孤立无援的乘车人的求助后，都会开车载着所有人到求助者所在的公路旁。除了拨打 911 外他们基本没有什么可做的，但这足以让他们感觉自己成为了英雄。

+ +

短小精悍的 Doyon 有着一口浓厚的新英格兰口音，并且非常喜欢《星际迷航》和阿西莫夫的小说。当他在《大众机械》上看到一则“组装你的专属个人计算机”构件广告时，就央求祖父给他买一套，接下来 Doyon 花了数月的时间把计算机组装起来并连接到 Internet 上去。与鲜为人知的 CB 电波相比，在线聊天室确实不可同日而语。“我只需要点一下按钮，再选中某个家伙的名字，然后我就可以和他聊天了，” Doyon 在最近回忆时说道，“这真的很惊人。”

+ +

十四岁那年，Doyon 离家出走，两年后他搬到了马萨诸塞州的剑桥，那里是一个新出现的计算机反主流文化的中心。同一时间，早在 34 年前就已由麻省理工学院的铁路狂热爱好者们创立的铁路模型技术俱乐部，已经演变成了“黑客”——也是推广该词的第一个组织。Richard Stallman，在那时还是一名任职于麻省理工学院人工智能实验室的计算机科学家，指出早期黑客们比起引发技术战争更乐于讨论“哥德尔、艾舍尔、巴赫”之类的话题。“我们没有任何约束”，Stallman 说，“这不是一项运动，而是一种可以让人们相互留下深刻印象的行为。”其中有些“行为”很有趣（制作电子游戏）；有些非常实用（提高计算机处理速度）；还有些则属于发生在真实世界里的恶作剧（在校园内放置模拟街道标识）。Michael Patton，在七十年代里管理着铁路模型技术俱乐部的人，谈起初代黑客间不成文的规定，说第一条就是“不要搞破坏”。

+ +

在剑桥，Doyon 以打零工和乞讨为生，他宁愿为了自由而睡在公园的长椅上，也不愿被单调的固定工作所束缚。1985 年，他和其他六个活跃分子共同组建了一支电子“义勇军”。模仿“动物解放阵线”，他们称呼自己为“人民解放阵线”（Peoples Liberation Front，PLF）。所有人都使用化名：如组织的创建者，声称自己是老兵的一位高大中年男子，自称“Commander Adama”；Doyon 则选择了“Commander X”这个称呼。受 “Merry Pranksters” 启示，他们在 Grateful Dead 的演唱会上出售 LSD（lysergic acid diethylamide，麦角酸酰二乙胺，一种迷幻药），并用收入的一部分购置了一辆二手校车，以及扩音器、相机，还有电源充电器。同时在剑桥租了一间地下公寓，Doyon 偶尔会在那里歇息。

+ +

Doyon 深深地沉溺于计算机中，虽然他并不是一位专业的程序员。在过去一年的几次谈话中，他告诉我他将自己视为激进主义分子，继承了 Abbie Hoffman 和 Eldridge Cleaver 的激进传统；技术不过是他抗议的工具。八十年代，哈佛大学和麻省理工学院的学生们举行集会，强烈抗议他们的学校从南非撤资。为了帮助抗议者通过安全渠道进行交流，PLF 制作了无线电套装：移动调频发射器、伸缩式天线，还有麦克风，所有部件都内置于背包内。Willard Johnson，麻省理工学院的一位激进分子和政治学家，表示黑客们出席集会并不意味着一次变革。“我们的大部分工作仍然是通过扩音器来完成的，”他解释道。

+ +

1992 年，在 Grateful Dead 的一场印第安纳的演唱会上，Doyon 秘密地向一位瘾君子出售了 300 粒药。由此他被判决在印第安纳州立监狱服役十二年，后来改为五年。服役期间，他对宗教和哲学产生了浓厚的兴趣，并于鲍尔州立大学学习了相应课程。

+ +

1994 年，第一款商业 Web 浏览器网景领航员正式发布，同一年 Doyon 被捕入狱。当他出狱并再次回到剑桥后，PLF 依然活跃着，并且他们的工具有了实质性的飞跃。Doyon 回忆起和他入狱之前的变化，“非常巨大——好比是‘烽火狼烟’跟‘电报传信’之间那么大的差距。”黑客们入侵了一个印度的军事网站，并修改其首页文字为“拯救克什米尔”。在塞尔维亚，黑客们攻陷了一个阿尔巴尼亚网站。Stefan Wray，一位早期网络激进主义分子，为一次纽约“反哥伦布日”集会上的黑客行径辩护。“我们视之为电子形式的公众抗议，”他告诉大家。

+ +

1999 年，美国唱片业协会因为版权侵犯问题起诉了 Napster，一款文件共享软件。最终，Napster 于 2001 年关闭。Doyon 与其他黑客使用分布式拒绝服务（Distributed Denial of Service，DDoS，使大量数据涌入网站导致其响应速度减缓直至奔溃）的手段，攻击了美国唱片业协会的网站，使之停运时间长达一星期之久。Doyon为自己的行为进行了辩解，并高度赞扬了其他的“黑客主义者”。“我们很快意识到保卫 Napster 的战争象征着保卫 Internet 自由的战争，”他在后来写道。

+ +

2008 年的一天，Doyon 和 “Commander Adama” 在剑桥的 PLE 地下公寓相遇。Adama 当着 Doyon 的面点击了癫痫基金会的一个链接，与意料中将要打开的论坛不同，出现的是一连串闪烁的彩光。有些癫痫病患者对闪光灯非常敏感——这完全是出于恶意，有人想要在无辜群众中诱发癫痫病。已经出现了至少一名受害者。

+ +

Doyon 愤怒了。他质问 Adama 什么样的人才会做出这样的事来。

+ +

“你听说过‘匿名者’组织吗？” Adama 问。

+ +

+ +

2003 年，一位来自纽约的已经患病 15 年的失眠症患者 Christopher Poole，推出了 4chan 讨论社区，在这里用户们可以随意发布照片或者尖锐评论。随后其关注点迅速从动漫延伸到许多 Internet 的早期文化基因，如：LOLcats、Chocolate Rain、RickRolls。当用户没有按照屏幕上的要求输入昵称时，将会得到系统默认的“匿名者”（Anonymous）称呼。

+ +
+ +
“我得谈谈我的感受。”
+ +

Poole 希望匿名这一举措可以延续社区的尖锐性因素。“我们无意参与理智的涉外事件讨论，”他在网站上写道。4chan 社区里最具价值的事之一便是寻求“挑起强烈的争端”（lulz），这个词源自缩写 LOL。Lulz 经常是通过分享充满孩子气的笑话或图片来实现的，它们中的大部分不是色情的就是下流的。其中最令人震惊的部分被贴在了网站的“/b/”版块上，这里的用户们称呼自己为“/b/tards”。Doyon 知道 4chan 这个社区，但他认为那些用户是“一群愚昧无知的顽童”。2004 年前后，/b/ 上的部分用户开始把“匿名者”视为一个独立的实体。

+ +

这是一个全新的黑客团体。“这不是一个传统意义上的组织，”一位领导计算机安全工作的研究员 Mikko Hypponen 告诉我——倒不如，视之为一个非传统的亚文化群体。Barrett Brown，德克萨斯州的一名记者,同时也是众所周知的“匿名者”高层领导，把“匿名者”描述为“一连串前仆后继的伟大友谊”。无需任何会费或者入会仪式。任何想要加入“匿名者”组织，成为一名匿名者（Anon）的人，都可以通过简短的象征性的宣誓加入。

+ +

尽管 4chan 的关注焦点是一些琐碎的话题，但许多匿名者认为自己就是“正义的十字军”。如果网上有不良迹象出现，他们就会发起具有针对性的治安维护行动。不止一次，他们以未成年少女的身份套取恋童癖的私人信息，然后把这些信息交给警察局。其他匿名者则是政治的厌恶者，为了挑起争端想方设法散布混乱的信息。他们中的一些人在 /b/ 上发布看着像是雷管炸弹的图片；另一些则叫嚣着要炸毁足球场并因此被联邦调查局逮捕。2007 年，一家洛杉矶当地的新闻联盟机构称呼“匿名者”组织为“互联网负能量制造机”。

+ +

2008 年 1 月，Gawker Media 上传了一段关于汤姆克鲁斯大力吹捧山达基优点的视频。这段视频是受版权保护的，山达基教会致信 Gawker，勒令其删除这段视频。“匿名者”组织认为教会企图控制网络信息。“是时候让 /b/ 来干票大的了，”有人在 4chan 上写道。“我说的是‘入侵’或者‘攻陷’山达基官方网站。”一位匿名者使用 YouTube 放出一段“新闻稿”，其中包括暴雨云视频和经过计算机处理的语音。“我们要立刻把你们从 Internet 上赶出去，并且在现有规模上逐渐瓦解山达基教会，”那个声音说，“你们无处可躲。”不到一个星期，这段 YouTube 视频的点击率就超过了两百万次。

+ +

“匿名者”组织已经不仅限于 4chan 社区。黑客们在专用的互联网中继聊天（Internet Relay Chat channels，IRC 聊天室）频道内进行交流，协商策略。通过 DDoS 攻击手段，他们使山达基的主网站间歇性崩溃了好几天。匿名者们制造了“谷歌炸弹”，由此导致 “dangerous cult” 的搜索结果中的第一条结果就是山达基主网站。其余的匿名者向山达基的欧洲总部寄送了数以百计的披萨，并用大量全黑的传真单耗干了洛杉矶教会总部的传真机墨盒。山达基教会，据报道拥有超过十亿美元资产的组织，当然能经得起墨盒耗尽的考验。但山达基教会的高层可不这么认为，他们还收到了严厉的恐吓，由此他们不得不向 FBI 申请逮捕“匿名者”组织的成员。

+ +

2008 年 3 月 15 日，在从伦敦到悉尼的一百多个城市里，数以千计匿名者们游行示威山达基教会。为了切合“匿名”这个主题，组织者下令所有的抗议者都应该佩戴相同的面具。深思熟虑过蝙蝠侠后，他们选定了 2005 年上映的反乌托邦电影《 V 字仇杀队》中 Guy Fawkes 的面具。“在每个大城市里都能以很便宜的价格大量购买，”广为人知的匿名者、游行组织者之一 Gregg Housh 告诉我说道。漫画式的面具上是一个的脸颊红润的男人，八字胡，有着灿烂的笑容。

+ +

匿名者们并未“瓦解”山达基教会。并且汤姆克鲁斯的那段视频任然保留在网络上。匿名者们证明了自己的顽强。组织选择了一个相当浮夸的口号：“我们是一体。绝不宽恕。永不遗忘。相信我们。”（We are Legion. We do not forgive. We do not forget. Expect us.）

+ +

+ +

2010 年，Doyon 搬到了加利福尼亚州的圣克鲁斯，并加入了当地的“和平阵营”组织。利用从木材堆置场偷来的木头，他在山上盖起了一间简陋的小屋，“借用”附近住宅的 WiFi，使用太阳能电池板发电，并通过贩卖种植的大麻换取现金。

+ +

与此同时，“和平阵营”维权者们每天晚上开始在公共场所休息，以此抗议圣克鲁斯政府此前颁布的“流浪者管理法案”，他们认为这项法案严重侵犯了流浪者的生存权。Doyon 出席了“和平阵营”的会议，并在网上发起了抗议活动。他留着蓬乱的红色山羊胡，戴一顶米黄色软呢帽，像军人那样不知疲倦。因此维权者们送给了他“罪恶制裁克里斯”的称呼。

+ +

“和平阵营”的成员之一 Kelley Landaker 曾几次和 Doyong 讨论入侵事宜。Doyon 有时会吹嘘自己的技术是多么的厉害，但作为一名资深程序员的 Landaker 却不为所动。“他说得很棒，但却不是行动派的，”Landaker 告诉我。不过在那种场合下，的确更需要一位富有激情的领导者，而不是埋头苦干的技术员。“他非常热情并且坦率，”另一位成员 Robert Norse 如是对我说。“他创造出了大量的能够吸引媒体眼球的话题。我从事这行已经二十年了，在这一点上他比我见过的任何人都要厉害。”

+ +

Doyon 在 PLF 的上司，Commander Adama 仍然住在剑桥，并且通过电子邮件和 Doyon 保持着联络，他下令让 Doyon 潜入“匿名者”组织。以此获知其运作方式，并伺机为 PLF 招募新成员。因为癫痫基金会网站入侵事件的那段不愉快回忆，Doyon 拒绝了 Adama。Adama 给 Doyon 解释说，在“匿名者”组织里不怀好意的黑客只占极少数，与此相反，这个组织经常会有一些的轰动世界举动。Doyon 对这点表示怀疑。“4chan 怎么可能会轰动世界？”他质问道。但出于对 PLF 的忠诚，他还是答应了 Adama 的请求。

+ +

Doyon 经常带着一台宏基笔记本电脑出入于圣克鲁斯的一家名为 Coffee Roasting Company 的咖啡厅。“匿名者”组织的 IRC 聊天室主频道无需密码就能进入。Doyon 使用 PLF 的昵称进行登录并加入了聊天室。一段时间后，他发现了组织内大量的专用匿名者行动聊天频道，这些频道的规模更小，并相互重复。要想参与行动，你必须知道行动的专用聊天频道名称，并且聊天频道随时会因为陌生的闯入者而进行变更。这套交流系统并不具备较高的安全系数，但它的确很凑效。“这些专用行动聊天频道确保了行动机密的高度集中，”麦吉尔大学的人类学家 Gabriella Coleman 告诉我。

+ +

有些匿名者提议了一项行动，名为“反击行动”。如同新闻记者 Parmy Olson 于 2012 年在书中写道的，“我们是匿名者，”这项行动成为了又一次支援文件共享网站，如 Napster 的后继者海盗湾（Pirate Bay），的行动的前奏，但随后其目标却扩展到了政治领域。2010 年末，在美国国务院的要求下，包括万事达、Visa、PayPal 在内的几家公司终止了对维基解密，一家公布了成百上千份外交文件的民间组织，的捐助。在一段网络视频中，“匿名者”组织扬言要进行报复，发誓会对那些阻碍维基解密发展的公司进行惩罚。Doyon 被这种抗议企业的精神所吸引，决定参加这次行动。

+ +
+ +
潘多拉的魔盒
+ +

在十二月初的“反击行动”中，“匿名者”组织指导那些新成员，或者说新兵，关于“如何他【哔~】加入组织”，教程中提到“首先配置你【哔~】的网络，这他【哔~】的很重要。”同时他们被要求下载“低轨道离子炮”，一款易于使用的开源软件。Doyon 下载了软件并在聊天室内等待着下一步指示。当开始的指令发出后，数千名匿名者将同时发动进攻。Doyon 收到了含有目标网址的指令——目标是，www.visa.com——同时，在软件的右上角有个按钮，上面写着“IMMA CHARGIN MAH LAZER.”（“反击行动”同时也发动了大量的复杂精密的入侵进攻。）几天后，“反击行动”攻陷了万事达、Visa、PayPal 公司的主页。在法院的控告单上，PayPal 称这次攻击给公司造成了 550 万美元的损失。

+ +

但对 Doyon 来说，这是切实的激进主义体现。在剑桥反对种族隔离的行动中，他不能立即看到结果；而现在，只需指尖轻轻一点，就可以在攻陷大公司网站的行动中做出自己的贡献。隔天，赫芬顿邮报上出现了“万事达沦陷”的醒目标题。一位得意洋洋的匿名者发推特道：“有些事情维基解密是无能为力的。但这些事情却可以由‘反击行动’来完成。”

+ +

+ +

2010 年的秋天，“和平阵营”的抗议活动终止，政府只做出了轻微的让步，“流浪者管理法案”仍然有效。Doyon 希望通过借助“匿名者”组织的方略扭转局势。他回忆当时自己的想法，“也许我可以发动‘匿名者’组织来教训这种看似不堪一击的市政府网站，这些人绝对会【哔~】地赞同我的提议。最终我们将使得市政府永久性的废除‘流浪者管理法案’。”

+ +

Joshua Covelli 是一位 25 岁的匿名者，他的昵称是“Absolem”，他非常钦佩 Doyon 的果敢。“现在我们的组织完全是他【哔~】各种混乱的一盘散沙，”Covelli 告诉我道。在“Commander X”加入之后，“组织似乎开始变得有模有样了。”Covelli 的工作是俄亥俄州费尔伯恩的一所大学接待员，他从不了解任何有关圣克鲁斯的政治。但是当 Doyon 提及帮助“和平阵营”抗击活动的计划后，Covelli 立即回复了一封表示赞同的电子邮件：“我期待这样的行动很久了。”

+ +

Doyon 使用 PLF 的昵称邀请 Covelli 在 IRC 聊天室进行了一次秘密谈话：

+ +
Absolem：抱歉，有个比较冒犯的问题...请问 PLF 也是组织的一员吗？
+ +
Absolem：我会这么问，是因为我在频道里看过你的聊天记录，你像是一名训练有素的黑客，不太像是来自组织里的成员。
+ +
PLF：不不不，你的问题一点也不冒犯。很高兴遇到你。PLF 是一个来自波士顿的黑客组织，已经成立 22 年了。我在 1981 年就开始了我的黑客生涯，但那时我并没有使用计算机，而是使用的 PBX（Private Branch Exchange，电话交换机）。
+ +
PLF：我们组织内所有成员的年龄都超过了 40 岁。我们当中有退伍士兵和学者。并且我们的成员“Commander Adama”，正在躲避一大帮警察还有间谍的追捕。
+ +
Absolem：听起来很棒！我对这次行动很感兴趣，不知道我是否可以提供一些帮助，我们的组织实在是太混乱了。我的电脑技术还不错，但我在入侵技术上还完全是一个新手。我有一些小工具，但不知道怎么去使用它们。
+ +

庄重的入会仪式后，Doyon 正式接纳 Covelli 加入 PLF：

+ +
PLF：把所有可能对你不利的【哔~】敏感文件加密。
+ +
PLF：还有，想要联系任何一位 PLF 成员的话，给我发消息就行。从现在起，请叫我... Commander X。
+ +

2012 年，美联社称“匿名者”组织为“一伙训练有素的黑客”；Quinn Norton 在《连线》杂志上发文称“‘匿名者’组织可以入侵任何坚不可摧的网站”，并在文末赞扬他们为“一群卓越的民间黑客”。事实上，有些匿名者的确是很有天赋的程序员，但绝大部分成员根本不懂任何技术。人类学家 Coleman 告诉我只有大约五分之一的匿名者是真正的黑客——其他匿名者则是“极客与抗议者”。

+ +

2010 年 12 月 16 日，Doyon 以 Commander X 的身份向几名记者发送了电子邮件。“明天当地时间 12：00 的时候，‘人民解放阵线’组织与‘匿名者’组织将大举进攻圣克鲁斯政府网站”，他在邮件中写道，“12:30 之后我们将恢复网站的正常运行。”

+ +

圣克鲁斯数据中心的工作人员收到了警告，匆忙地准备应对攻击。他们在服务器上运行起安全扫描软件，并向当地的互联网供应商 AT & T 求助，后者建议他们向 FBI 报警。

+ +

第二天，Doyon 走进了一家星巴克并启动了笔记本电脑。即便是在这样一个小镇上，Doyon 也显得格外醒目：一个疲惫的流浪汉疯狂地敲击着键盘。随后，Covelli 和他在一间秘密聊天室碰头。

+ +
PLF：去社区，登录——检查一下右上角的“聊天”菜单栏，上面有今天的具体方案。感谢你对我们的支持。
+ +
Absolem：一切为了 PLF，长官。
+ +

他们都打开了 DDoS 软件。尽管只有少数人参加了这次“和平阵营”的行动，但 Doyon 好似统率千军万马般下令：

+ +
PLF：注意：每一位支持 PLF 或者站在我们这边的朋友——还有那些对抗邪恶保卫正义的勇士们：‘和平阵营’行动进行中，战斗的号角已经响起！目标：www.co.santa-cruz.ca.us。随意开火。重复指令：开火！
+ +
Absolem：收到，长官。
+ +

数据中心的工作人员紧张地盯着服务器，上面反馈出一连串拒绝服务的请求。尽管他们尽了最大的努力，网站还是崩溃了。25 分钟后，Doyon 决定遵守承诺。他下令“停止攻击”，政府网站开始恢复了正常运行。（这次攻击后，“流浪者管理法案”依旧没有废除。）

+ +

Doyon 没有时间去庆祝胜利，他显得焦躁不安。“我得走了，”他告诉 Covelli。他飞一般得逃回了山中小屋。Doyon 的感觉是正确的：一位 FBI 的探员早就在 IRC 上盯住了他。这位 FBI 的探员已经获许搜查 Doyon 的笔记本电脑。

+ +

几周后，Doyon 的食物吃完了，他不得不下山进行采购。当 Doyon在 Coffee Roasting Company 咖啡厅逗留的时候，两位联邦探员走了进来将他拘捕。Doyon 给“和平阵营”的创建者，同时也是一名律师的 Ed Frey 打了一个电话，Ed Frey 来到了警察局。Doyon 告诉了 Frey 他的另一个身份“Commander X”的事。

+ +

随后 Doyon 被释放，但 FBI 没收了他的笔记本电脑，里面满是犯罪证据。Frey 一个几乎不了解网络世界的维权律师，把 Doyon 载回了他的山边露营。“接着你要怎么办？”Frey 问道。

+ +
+ +
“Zach 很聪明... 并且... 是一个天才... 但.. 你们... 不在一个班。”
+ +

Doyon 引用了一句电影台词。“拼命地跑，”他说。“我会躲起来，尽可能保持我的行动自由，用尽全力和这帮杂种们作斗争。”Frey 给了他两张 20 美元的钞票并祝他好运。

+ +

+ +

Doyon 搭着便车来到了旧金山，并在这里呆了三个月。他经常混迹于 Haight 大街 Ashbury 区的一家杂乱的咖啡馆里，在计算机前一坐就是几个小时，只有在抽烟时他才会起身走到室外活动。

+ +

2011 年 1 月，Doyon 联系了新闻记者兼匿名者的 Barrett Brown。“我们的下一步计划是什么？”Doyon 问道。

+ +

“突尼斯，” Brown 答道。

+ +

“我知道，那是中东地区的一个国家，” Doyon 继续问，“然后呢？”

+ +

“我们准备打倒那里的独裁者，” Brown 再次答道。

+ +

“啊？！那里有一位独裁者吗？” Doyon 有点惊讶。

+ +

几天后，“突尼斯行动”正式展开。Doyon 作为参与者向突尼斯政府域名下的电子邮箱发送了大量的垃圾邮件，以此阻塞其服务器。“我会提前写好关于那次行动邮件，接着一次又一次地把它们发送出去，” Doyon 说，“有时候实在没有时间，我就只简短的写上一句问候对方母亲的的话，然后发送出去。”短短一天时间里，匿名者们就攻陷了包括突尼斯证券交易所、工业部、总统办公室、总理办公室在内的多个网站。他们把总统办公室网站的首页替换成了一艘海盗船的图片，并配以文字“‘报复’是个贱人，不是吗？”

+ +

Doyon 不时会谈起他的网上“战斗”经历，似乎他刚从弹坑里爬出来一样。“伙计，自从干了这行我就变黑了，”他向我诉苦道。“你看我的脸，全是抽烟的时候熏的——而且可能已经粘在我的脸上了。我仔细地照过镜子，毫不夸张地说我简直就是一头棕熊。”很多个夜晚，Doyon 都是在 Golden Gate 公园里露营过夜的。“我就那样干了四天，我看了看镜子里的‘我’，感觉还可以——但其实我觉得‘我’也许应该去吃点东西、洗个澡了。”

+ +

“匿名者”组织接着又在 YouTube 上声明了将要进行的一系列行动：“利比亚行动”、“巴林行动”、“摩洛哥行动”。作为解放广场事件的抗议者，Doyon 参与了“埃及行动”。在 Facebook 针对这次行动的宣传专页中，有一个为当地示威者准备的“行动套装”链接。“行动套装”通过文件共享网站 Megaupload 进行分发，其中含有一份加密软件以及应对瓦斯袭击的保护措施。并且在不久后，埃及政府关闭了埃及的所有互联网及子网络的时候，继续向当地抗议者们提供连接网络的方法。

+ +

2011 年夏季，Doyon 接替 Adama 成为 PLF 的最高指挥官。Doyon 招募了六个新成员，并力图发展 PLF 成为“匿名者”组织的中坚力量。Covelli 成为了他的其中一技位术顾问。另一名黑客 Crypt0nymous 负责在 YouTube 上发布视频；其余的人负责研究以及组装电子设备。与松散的“匿名者”组织不同，PLF 内部有一套极其严格的管理体系。“Commander X 事必躬亲，”Covelli 说。“这是他的行事风格，也许不能称之为一种风格。”一位创立了 AnonInsiders 博客的黑客通过加密聊天告诉我，他认为 Doyon 总是一意孤行——这在“匿名者”组织中是很罕见的现象。“当我们策划发起一项行动时，他并不在乎其他人是否同意，”这位黑客补充道，“他会一个人列出行动方案，确定攻击目标，登录 IRC 聊天室，接着告诉所有人在哪里‘碰头’，然后发起 DDoS 攻击。”

+ +

一些匿名者把 PLF 视为可有可无的部分，认为 Doyon 的所作所为完全是个天大的笑柄。“他是因为吹牛出名的，”另一名昵称为 Tflow 的匿名者 Mustafa Al-Bassam 告诉我。不过，即使是那些极度反感 Doyon 的狂妄自大的人，也不得不承认他在“匿名者”组织发展过程中的重要性。“他所倡导的强硬路线有时很凑效，有时则完全不起作用，” Gregg Housh 说，并且补充道自己和其他优秀的匿名者都曾遇到过相同的问题。

+ +

“匿名者”组织对外坚持声称自己是不分层次的平等组织。在由 Brian Knappenberger 制作的一部纪录片，《我们是一个团体》中，一名成员使用“一群鸟”来比喻组织，它们轮流领飞带动整个组织不断前行。Gabriella Coleman 告诉我，这个比喻不太切合实际，“匿名者”组织内实际上早就出现了一个非正式的领导阶层。“领导者非常重要，”她说。“有四五个人可以看做是我们的领头羊。”她把 Doyon 也算在了其中。但是匿名者们仍然倾向于反抗这种具有体系的组织结构。在一本即将出版的关于“匿名者”组织的书，《黑客、骗子、告密者、间谍》中，Coleman 这么写道，在匿名者中，“成员个体以及那些特立独行的人依然在一些重大事件上保持着服从的态度，优先考虑集体——特别是那些能引发强烈争端的事件。”

+ +

匿名者们谑称那些特立独行的成员为“自尊心超强的疯子”和“想让自己出名的疯子”。（不过许多匿名者已经不会再随便给他人取那种具有冒犯性的称号了。）“但还是有令人惊讶的极少数成员违反规则”打破传统上的看法，Coleman 说。“这么做的人，像 Commander X 这样的，都会在组织里受到排斥。”去年，在一家网络论坛上，有人写道，“当他开始把自己比作‘蝙蝠侠’的时候我就不想理他了。”

+ +

Peter Fein，是一位以 n0pants 为昵称而出名的网络激进分子，也是众多反对 Doyon 的浮夸行为的众多匿名者之一。Fein 浏览了 PLF 的网站，其封面上有一个徽章，还有关于组织的宣言——“为了解放众多人类的灵魂而不断战斗”。Fein 沮丧的发现 Doyon 早就使用真名为这家网站注册过了，使他这种，以及其他想要找事的匿名者们无机可乘。“如果有人要对我的网站进行 DDoS 攻击，那完全可以，” Fein 回想起通过私密聊天告诉 Doyon 时的情景，“但如果你要这么做了的话，我会揍扁你的屁股。”

+ +

2011 年 2 月 5 日，《金融时报》报道了在一家名为 HBGary Federal 的网络安全公司里，首席执行官 HBGary Federal 已经得到了“匿名者”组织骨干成员名单的消息。Barr 的调查结果表明，三位最高领导人其中之一就是‘ Commander X’，这位潜伏在加利福尼亚州的黑客有能力“策划一些大型网络攻击事件”。Barr 联系了 FBI 并提交了自己的调查结果。

+ +

和 Fein 一样，Barr 也发现了 PLF 网站的注册法人名为 Christopher Doyon，地址是 Haight 大街。基于 Facebook 和 IRC 聊天室的调查，Barr 断定‘ Commander X’的真实身份是一名家庭住址在 Haight 大街附近的网络激进分子 Benjamin Spock de Vries。Barr 通过 Facebook 和 de Vries 取得了联系。“请告诉组织里的普通阶层，我并不是来抓你们的，” Barr 留言道，“只是想让‘领导阶层’知晓我的意图。”

+ +

“‘领导阶层’？ 2333，笑死我了，” de Vries 回复道。

+ +

《金融时报》发布报道的第二天，“匿名者”组织就进行了反击。HBGary Federal 的网站被进行了恶意篡改。Barr 的私人 Twitter 账户被盗取，他的上千封电子邮件被泄漏到了网上，同时匿名者们还公布了他的住址以及其他私人信息——这是一系列被称作“doxing”的惩罚。不到一个月后，Barr 就从 HBGary Federal 辞职了。

+ +

+ +

2011 年 4 月，Doyon 离开了旧金山搭便车向西部前行，过着夜晚露宿公园、白天混迹于星巴克的生活。他的背包里只有一台笔记本电脑、Guy Fawkes 面具，还有在 Pall 超市里购买的一些东西。

+ +
+ +
“这是我在 TED 夏令营里学到的东西。”
+ +

他时刻关注着“匿名者”组织的内部消息。那年春季，在 Barr 调查报告中提到的六位匿名者精锐成员，组建了“LulzSec 安全”组织（Lulz Security），简称 LulzSec。这个组织正如其名，这些成员认为“匿名者”组织已经变得太过严肃；他们的目标是重新引发起那些“能挑起强烈争端”的事件。当“匿名者”组织还在继续支持“阿拉伯之春”的抗议者的时候，LulzSec 入侵了公共电视网（Public Broadcasting Service，PBS）网站，并发布了一则虚假声明称已故说唱歌手 Tupac Shakur 仍然生活在新西兰。

+ +

匿名者之间会通过 Pastebin.com 网站来共享文字。在这个网站上，LulzSec 发表了一则声明，称“很不幸，我们注意到北约和我们的好总统巴拉克，奥萨马·本·美洲驼（拉登同学）的好朋友，来自 24 世纪的奥巴马，最近明显提高了对我们这些黑客的关注程度。他们把黑客入侵行为视作一种战争的表现。”目标越高远，挑起的纷争就越大。6 月 15 日，LulzSec 表示对 CIA 网站受到的袭击行为负责，他们发表了一条推特，上面写道“目标击毙（Tango down，亦即target down）—— cia.gov ——这是起挑衅行为。”

+ +

2011 年 6 月 20 日，LulzSec 的一名十九岁的成员 Ryan Cleary 因为对 CIA 的网站进行了 DDoS 攻击而被捕。7 月，FBI 探员逮捕了七个月前对 PayPal 进行 DDoS 攻击的其他十四名黑客。这十四名黑客，每人都面临着 15 年的牢狱之灾以及 500 万美元的罚款。他们因为图谋不轨以及故意破坏互联网，而被控违反了计算机欺诈与滥用处理条例。（该法案允许检察官进行酌情处置，并在去年网络激进分子 Aaron Swartz 因为被判处 35 年牢狱之灾而自杀身亡之后，受到了广泛的质疑和批评。）

+ +

LulzSec 的成员之一 Jake (Topiary) Davis 因为付不起法律诉讼费，给组织的成员们写了一封请求帮助的信件。Doyon 进入了 IRC 聊天室把 Davis 需要帮助的消息进行了扩散：

+ +
CommanderX：那么请大家阅读信件并给予 Topiary 帮助...
+ +
Toad：你真是和【哔~】一样消息灵通。
+ +
Toad：这么说你得到 Topiary 的消息了？
+ +
CommanderX：Toad 你这个混蛋！
+ +
Katanon：唉...
+ +

Doyon 越来越大胆。他在佛罗里达州当局逮捕了支持流浪者的激进分子后，就 DDoS 了奥兰多商务部商会网站。他使用个人笔记本电脑通过公用无线网络实施了攻击，并且没有花费太多精力来隐藏自己的网络行踪。“这种做法很勇敢，但也很愚蠢，”一位自称 Kalli 的 PLF 的资深成员告诉我。“他看起来并不在乎是否会被抓。他完全是一名自杀式黑客。”

+ +

两个月后，Doyon 参与了针对旧金山湾区快速交通系统（Bay Area Rapid Transit）的 DDoS 攻击，以此抗议一名 BART 的警官杀害一名叫做 Charles Hill 的流浪者的事件。随后 Doyon 现身“CBS 晚间新闻”为这次行动辩护，当然，他处理了自己的声音，把自己的脸用香蕉进行替代。他把 DDoS 攻击比作为公民的抗议行为。“与占用 Woolworth 午餐柜台的座位相比，这真的没什么不同，真的，”他说道。CBS 的主播 Bob Schieffer 笑称：“就我所见，它并不完全是一项民权运动。”

+ +

2011 年 9 月 22 日，在加利福尼亚州的一家名为 Mountain View 的咖啡店里，Doyon 被捕，同时面临着“使用互联网非法破坏受保护的计算机”罪名指控。他被拘留了一个星期的时间，接着在签署协议之后获得假释。两天后，他不顾律师的反对，宣布将在圣克鲁斯郡法院召开新闻发布会。他梳起了马尾辫，戴着一副墨镜、一顶黑色海盗帽，同时还在脖子上围了一条五彩手帕。

+ +

Doyon 通过非常夸大的方式披露了自己的身份。“我就是 Commander X，”他告诉蜂拥的记者。他举起了拳头。“作为‘匿名者’组织的一员，作为一名核心成员，我感到非常的骄傲。”他在接受一名记者的采访时说，“想要成为一名顶尖黑客的话，你只需要准备一台电脑以及一副墨镜。任何一台电脑都行。”

+ +

Kalli 非常担心 Doyon 会不小心泄露组织机密或者其他匿名者的信息。“这是所有环节中最薄弱的地方，如果这里出问题了，那么组织就完了，”他告诉我。曾在“和平阵营行动”中给予 Doyon 大力帮助的匿名者 Josh Covelli 告诉我，当他在网上看见 Doyon 的新闻发布会视频的时候，他感觉瞬间“下巴掉地下了”。“他的所作所为变得越来越不可捉摸，” Covelli 评价道。

+ +

三个月后，Doyon 的指定律师 Jay Leiderman 出席了圣荷西联邦法庭的辩护。Leiderman 已经好几个星期没有得到 Doyon 的消息了。“我需要得知被告无法出席的具体原因，”法官说。Leiderman 无法回答。Doyon 再次缺席了两星期后的另一场听证会。检控方表示：“很明显，看来被告已经逃跑了。”

+ +

7

+ +

“Xport 行动”是“匿名者”组织进行的所有同类行动中的第一个行动。这次行动的目标是协助如今已经背负两项罪名的通缉犯 Doyon 潜逃出国。负责调度的人是 Kalli 以及另一位曾在八十年代剑桥的迷幻药派对上和 Doyon 见过面的匿名者老兵。这位老兵是一位已经退休的软件主管，在组织内部威望很高。

+ +

Doyon 的终点站是这位软件主管的家，位于加拿大的偏远乡村。2011 年 12 月，他搭便车前往旧金山，并辗转来到了市区组织大本营。他找到了他的指定联系人，后者带领他到达了奥克兰的一家披萨店。凌晨 2 点，Doyon 通过披萨店的无线网络，接收了一条加密聊天消息。

+ +

“你现在靠近窗户吗？”那条消息问道。

+ +

“是的，” Doyon 回复道。

+ +

“往大街对面看。看见一个绿色的邮箱了吗？十五分钟后，你去站到那个邮箱旁边，把你的背包取下来，然后把你的面具放在上面。”

+ +

一连几个星期的时间，Doyon 穿梭于海湾地区的安全屋之间，按照加密聊天那头的指示不断行动。最后，他搭上了前往西雅图的长途公交车，软件主管的一个朋友在那里接待了他。这个朋友是一名非常富有的退休人员，他花费了通过谷歌地球来帮助 Doyon 规划前往加拿大的路线。他们共同前往了一家野外用品供应商店，这位朋友为 Doyon 购置了价值 1500 美元的商品，包括登山鞋以及一个全新的背包。接着他又开车载着 Doyon 北上，两小时后到达距离国界只有几百英里的偏僻地区。随后 Doyon 见到了 Amber Lyon。

+ +

几个月前，广播新闻记者 Lyon 曾在 CNN 的关于“匿名者”组织的节目里采访过 Doyon。Doyon 很欣赏她的报道，他们一直保持着联络。Lyon 要求加入 Doyon 的逃亡行程，为一部可能会发行的纪录片拍摄素材。软件主管认为这样太过冒险，但 Doyon 还是接受了她的请求。“我觉得他是想让自己出名，” Lyon 告诉我。四天的时间里，她用影像记录下了 Doyon 徒步北上，在林间露宿的行程。“那一切看起来不太像是仔细规划过的，” Lyon 回忆说。“他实在是无家可归了，所以他才会想要逃到国外去。”

+ +
+ +
“这里是我们存放各种感觉的仓库。如果你发现了某种感觉，把它带到这里然后锁起来。”
+ +

2012 年 2 月 11 日，Pastebin 上出现了一条消息。“PLF 很高兴的宣布‘ Commander X’，也就是 Christopher Mark Doyon，已经离开了美国的司法管辖区，抵达了加拿大一个比较安全的地方，”上面写着，“PLF 呼吁美国政府，希望政府能够醒悟过来并停止无谓的骚扰与监视行为——不要仅仅逮捕‘匿名者’组织的成员，对所有的激进组织应该一视同仁。”

+ +

8

+ +Doyon 和软件主管在加拿大的小木屋里呆了几天。在一次同 Barrett Brown 的聊天中，Doyon 难掩内心的喜悦之情。 + +
BarrettBrown：你现在应该足够安全了吧，其他的呢？...
+ +
CommanderX：是的，我现在很安全，现在加拿大既不缺钱也不缺藏身的地方。
+ +
CommanderX：Amber Lyon 想要你的一张照片。
+ +
CommanderX：去他【哔~】的怪人，Barrett，相信你会喜欢我告诉她应该怎样评价你的。
+ +
CommanderX：:-)
+ +
CommanderX：我告诉她你是一个英雄。
+ +
BarrettBrown：你才是真正的英雄...
+ +
BarrettBrown：很高兴你现在安全了
+ +
BarrettBrown：如果你还需要什么，告诉我一声就可以了
+ +
CommanderX：我会的，如果这种方式的确很凑效的话，可以让其他被通缉的人也这样逃出来....
+ +
BarrettBrown：当然，估计我们不久后也得这样了
+ +

在 Doyon 出逃十天后，《华尔街日报》上刊登了关于不久后升职为美国国家安全局及网络指挥部主任的 Keith Alexander 的报道，他在白宫举行的秘密会晤以及其他场合下，表达了对“匿名者”组织的高度关注。Alexander 发出警告，两年内，该组织必将会是国家电网改造的大患。参谋长联席会议的主席 General Martin Dempsey 告诉记者，这群人是国家的敌人。“他们有能力把这些使用恶意软件造成破坏的技术扩散到其他的边缘组织去，”随后又补充道，“我们必须防范这种情况发生。”

+ +

3 月 8 日，国会议员们在国会大厦附近的一个敏感信息隔离设施附近举行了关于网络安全的会议。包括 Alexander、Dempsey、美国联邦调查局局长 Robert Mueller，以及美国国土安全部部长 Janet Napolitano 在内的多名美国安全方面的高级官员出席了这次会议。会议上，通过计算机向与会者模拟了东部沿海地区电力设施可能会遭受到的网络攻击时的情境。“匿名者”组织目前应该还不具备发动此种规模攻击的能力，但安全方面的官员担心他们会联合其他更加危险的组织来共同发动攻击。“在我们着手于不断增加的网络风险事故时，政府仍在就具体的处理细节进行不断协商讨论，” Napolitano 告诉我。当谈及潜在的网络安全隐患时，她补充道，“我们通常会把‘匿名者’组织的行动当做 A 级威胁来应对。”

+ +

“匿名者”也许是当今世界上最强大的无政府主义黑客组织。即使如此，它却从未表现出过任何的会对公共基础设施造成破坏的迹象或意愿。一些网络安全专家称，那些关于“匿名者”组织的谣传太过危言耸听。“在奥兰多发布战前宣言和实际发动 Stuxnet 蠕虫病毒攻击之间是有很大的差距的，” Internet 研究与战略中心的一位职员 James Andrew Lewis 告诉我，这和 2007 年美国与以色列对伊朗原子能网站发动的黑客袭击有关。哈佛大学法学院的教授 Yochai Benkler 告诉我，“我们所看见的只是以主要防御为理由而进行的开销，否则，将很难自圆其说。”

+ +

Keith Alexander 最近刚从政府部门退休，他拒绝就此事发表评论，因为他并不能代表国家安全局、联邦调查局、中央情报局以及国土安全部。尽管匿名者们从未真正盯上过政府部门的计算机网络，但他们对于那些激怒他们的人有着强烈的报复心理。前国土安全部国家网络安全部门负责人 Andy Purdy 告诉我他们“害怕被报复，”无论机构还是个人，都不同意政府公然反对“匿名者”组织。“每个人都非常脆弱，”他说。

+ +

+ +

2012 年 3 月 6 日，Hector Xavier Monsegur，昵称为 Sabu 的 LulzSec 骨干成员，被发现是 FBI 派来的卧底。为了换取减刑，Monsegur 花费了数月的时间卧底，协助搜集其他 LulzSec 成员的罪证。同一天，五位匿名者领导被捕，同时面临着包括“计算机某犯罪”在内的多项罪名指控。联邦调查局的一名官员在接受福克斯新闻记者采访时说道，“这对那个组织是一个毁灭性的打击。我们的行动如同砍掉了 LulzSec 组织的头。”接下来的十个月里， Barrett Brown 收到了 17 项联邦罪名的指控，其中的大部分后来被撤销了。（他将在十月被宣判最终结果。）

+ +

Doyon 感到很烦躁，但他还是继续扮演着一名黑客——以此吸引关注。他在多伦多上映的纪录片上以戴着面具的匿名者形象出现。在接受《National Post》的采访时，他向记者大肆吹嘘未经证实的消息，“我们已经入侵了美国政府的所有机密数据库。现在的问题是我们该何时泄露这些机密数据，而不是我们是否会泄露。”

+ +

2013 年 1 月，在另一名匿名者介入俄亥俄州斯托本维尔未成年少女轮奸案，发起抗议行动之后，Doyon 重新启用了他两年前创办的网站 LocalLeaks，作为那起轮奸事件的信息汇总处理中心。如同许多其他“匿名者”组织的所作所为一样，LocalLeaks 网站非常具有影响力，但却也不承担任何责任。LocalLeaks 网站是第一家公布 12 分钟斯托本维尔高中毕业生猥亵视频的网站，这激起了众多当事人的愤怒。LocalLeaks 网站上同时披露了几份未被法庭收录的关于案件的材料，并且由此不小心透漏出了案件受害人的名字。Doyon向我承认他公开这些未经证实的信息的策略是存在争议的，但他同时回忆起自己当时的想法，“我们可以选择去除这些斯托本维尔案件的材料...也可以选择公开所有我们搜集的信息，基本上，给公众以提醒，不过，前提是你们得相信我们。”

+ +

2013 年 3 月，一个名为 Rustle League 的组织入侵了 Doyon 的 Twitter 账户，该组织此前经常挑衅“匿名者”组织。Rustle League 的领导者之一 Shm00p 告诉我，“我们的本意并不是伤害那些家伙，只不过，哦，那些家伙说的话你就当是在放屁好了——我会这么做只是因为我感到很好笑。” Rustle League 组织使用 Doyon 的账户发布了含有如 www.jewsdid911.org 链接这样的，种族主义和反犹太主义的信息。

+ +

2013 年 8 月 27 日，Doyon 发布了一则退出“匿名者”组织的声明。“我的一生都用在了追求正义和自由上，”他写道，“也许‘ Commander X’是无敌的，但我在这种高节奏的全球网络斗争中已经感到很累了，感觉自己好像病了。”各界对此反应不一，有同情的（“你是该休息了”），也有嘲讽的（“可怜的疯狂小老头。也许他现在有时间洗澡了”）。 Covelli 告诉我，“‘匿名者’的身份对他产生了较大的影响，他已经不能再应付了。”

+ + + +
1998 年 8 月 17 日 “我们还有‘巴黎’吗？仔细想想，我等会儿去检查一下。”
+ +

10

+ +

2013 年 11 月 5 日举行了第一次“百万面具游行”活动。在全世界四百五十个城市里，发起了数千人的支持“匿名者”组织的游行。伦敦的一名抗议者摘下了盖伊·福克斯面具后，露出了演员罗素·布兰德的脸。这种的迹象表明，“匿名者”组织已经深入到了流行文化中。

+ +

我参加了华盛顿的集会，Doyon 则呆在了加拿大观看现场直播。通过移动电话，我和 Doyon 不断交换着电子邮件。“只能坐在这里看直播而不能亲自去现场真的很令人沮丧——尤其是当这里面包含有你努力的结果的时候，”他在邮件里写道。“不过至少一切都已有所改变。”

+ +

我们约定了一次面谈。Doyon 坚持让我通过加密聊天把面谈的详细情况提前告诉他。我坐了几个小时的飞机，租车来到了加拿大的一个偏远小镇，并且禁用了我的电话。

+ +

最后，我在一个狭小安静的住宅区公寓里见到了 Doyon。他穿了一件绿色的军人夹克衫以及印有“匿名者”组织 logo 的 T 恤衫：一个脸被问号所替代的黑衣人形象。公寓里基本上没有什么家具，充满了一股烟味。他谈论起了美国政治（“我基本没怎么在众多的选举中投票——它们不过是暗箱操作的游戏罢了”），好战的伊斯兰教（“我相信，尼日利亚政府的人不过是相互勾结，以创建一个名为‘博科圣地’的基地组织的下属机构罢了”），以及他对“匿名者”组织的小小看法（“那些自称为怪人的人是真的是烂透了，意思是，邪恶的人”）。

+ +

Doyon 剃去了他的胡须，但他却显得更加憔悴了。他说那是因为他病了的原因，他几乎很少出去。很小的写字台上有两台笔记本电脑、一摞关于佛教的书，还有一个堆满烟灰的烟灰缸。另一面裸露的泛黄墙壁上挂着盖伊·福克斯面具。他告诉我，“所谓‘Commander X’不过是一个处于极度痛苦中的小老头罢了。”

+ +

在刚过去的圣诞节里，匿名者的新网站 AnonInsiders 的创建者拜访了 Doyon，并给他带来了馅饼和香烟。Doyon 询问来访的朋友是否可以继承自己的衣钵成为 PLF 的最高指挥官，同时希望能够递交出自己手里的“王国钥匙”——手里的所有密码，以及几份关于“匿名者”组织的机密文件。这位朋友委婉的拒绝了。“我有自己的生活，”他告诉了我拒绝的理由。

+ +

+ +

2014 年 8 月 9 日，当地时间下午 5 时 09 分，来自密苏里州圣路易斯郊区德尔伍德的一位说唱歌手同时也是激进分子的 Kareem (Tef Poe) Jackson，在 Twitter 上谈起了邻近城镇的一系列令人担忧的举措。“基本可以断定弗格森已经实施了戒严，任何人都无法出入，”他在 Twitter 上写道。“国内的朋友还有因特网上的朋友请帮助我们！！！”五个小时前，弗格森，一位十八岁的手无寸铁的非裔美国人 Michael Brown，被一位白人警察射杀。射杀警察声称自己这么做的原因是 Brown 意图伸手抢夺自己的枪支。而事发当时和 Brown 在一起的朋友 Dorian Johnson 却说，Brown 唯一做得不对的地方在于他当时拒绝离开街道中间。

+ +

不到两小时，Jackson 就收到了一位名为 CommanderXanon 的 Twitter 用户的回复。“你完全可以相信我们，”回复信息里写道。“你是否可以给我们详细描述一下现场情况，那样会对我们很有帮助。”近几周的时间里，仍然呆在加拿大的 Doyon 复出了。六月，他在还有两个月满 50 岁的时候，成功戒烟（“#戒瘾成功 #电子香烟功不可没 #老了，”他在戒烟成功后在 Twitter 上写道）。七月，在加沙地带爆发武装对抗之后，Doyon 发表 Twiter 支持“匿名者”组织的“拯救加沙行动”，并发动了一系列针对以色列网站的 DDoS 攻击。Doyon 认为弗格森枪击事件更加令人关注。抛开他本人的个性，他有在事件发展到引人注目之前的早期，就迅速注意该事件的能力。

+ +

“正在网上搜索关于那名警察以及当地政府的信息，” Doyon 发 Twitter 道。不到十分钟，他就为此专门在 IRC 聊天室里创建了一个频道。“‘匿名者’组织‘弗格森’行动正式启动，”他又发了一条 Twitter。但只有两个人转推了此消息。

+ +

次日早晨，Doyon 发布了一条链接，链接指向的是一个初具雏形的网站，网站首页有一条致弗格森市民的信息——“你们并不孤单，我们将尽一切努力支持你们”——以及致当地警察的警告：“如果你们对对弗格森的抗议者们滥用职权、骚扰，或者伤害了他们，我们绝对会让你们所有政府部门的网站瘫痪。这不是威胁，这是承诺。”同时 Doyon 呼吁有 130 万粉丝的“匿名者”组织的 Twitter 账号 YourAnonNews 给与支持。“请支持‘弗格森’行动”，他发送了消息。一分钟后，YourAnonNews 回复表示同意。当天，包含话题 #OpFerguson 的 Twitter 发表/转推了超过六千次。

+ +

这个事件迅速成为头条新闻，同时匿名者们在弗格森周围进行了大集会。与“阿拉伯之春行动”类似，“匿名者”组织向抗议者们发送了电子关怀包，包括抗暴指导（“把瓦斯弹捡起来回丢给警察”）与可打印的盖伊·福克斯面具。Jackson 和其他示威者在弗格森进行示威游行时，警察企图通过橡皮子弹和催泪瓦斯来驱散他们。“当时的情景真像是布鲁斯·威利斯的电影里的情节，” Jackson 后来告诉我。“不过巴拉克·奥巴马应该并不会支持‘匿名者’组织传授给我们的这些知识，”他笑称道。“让那些警察赶到束手无策真的是太爽了。”

+ +

有个域名是 www.opferguson.com 的网站，后来发现不过是一个骗局——一个用来收集访问者 ip 地址的陷阱，随后这些地址会被移交给执法机构。有些人怀疑 Commander X 是政府的线人。在 IRC 聊天室 #OpFerguson 频道，一个名叫 Sherlock 写道，“现在频道里每个人说的已经让我害怕去点击任何陌生的链接了。除非是一个我非常熟悉的网址，否则我绝对不会去点击。”

+ +

弗格森的抗议者要求当局公布射杀 Brown 的警察的名字。几天后，匿名者们附和了抗议者们的请求。有人在 Twitter 上写道，“弗格森警察局最好公布肇事警察的名字，否则‘匿名者’组织将会替他们公布。”8 月 12 的新闻发布会上，圣路易斯警察局的局长 Jon Belmar 拒绝了这个请求。“我们不会这样做，除非他们被某个罪名所指控，”他说道。

+ +

作为报复，一名黑客使用名为 TheAnonMessage 的 Twitter 账户公布了一条链接，该链接指向一段来自警察的无线电设备所记录的音频文件，文件记录时间是 Brown 被枪杀的两小时左右。TheAnonMessage 同时也把矛头指向了 Belmar，在 Twitter 上公布了这位警察局长的家庭住址、电话号码以及他的家庭照片——一张是他的儿子在长椅上睡觉，另一张则是 Belmar 和他的妻子的合影。“不错的照片，Jon，” TheAnonMessage 在 Twitter 上写道。“你的妻子在她这个年龄算是一个美人了。你已经爱她爱得不耐烦了吗？”一个小时后，TheAnonMessage 又以 Belmar 的女儿为把柄进行了恐吓。

+ +

Richard Stallman，来自 MIT 的初代黑客，告诉我虽然他在很多地方赞同“匿名者”组织的行为，但他认为这些泄露私人信息的攻击行为是要受到谴责的。即使是在国内，TheAnonMessage 的行为也受到了谴责。“为何要泄露无辜的人的信息到网上？”一位匿名者通过 IRC 发问，并且表示威胁 Belmar 的家人实在是“相当愚蠢的行为”。但是 TheAnonMessage 和其他的一些匿名者仍然进行着不断搜寻，并企图在将来再次进行泄露信息的攻击。在互联网上可以得到所有弗格森警察局警员的名字，匿名者们不断地搜索着信息，企图找出具体是哪一个警察找出杀害了 Brown。

+ +
+ +
1999 年 4 月 12 日 “我应该把镜头对向谁？”
+ +

8 月 14 日清晨，及位匿名者基于 Facebook 上的照片还有其他的证据，确定了射杀 Brown 的凶手是一位名叫 Bryan Willman 的 32 岁男子。根据一份 IRC 聊天记录，一位匿名者贴出了 Willman 的浮夸面孔的照片；另一位匿名者提醒道，“凶手声称自己的脸没有被任何人看到。”另一位昵称为 Anonymous|11057 的匿名者承认他对 Willman 的怀疑确实是“跳跃性的可能错误的逻辑过程推导出来的。”不过他还是写道，“我只是无法动摇自己的想法。虽然我没有任何证据，但我非常非常地确信就是他。”

+ +

TheAnonMessage 看起来被这次对话逗乐了，写道，“#愿逝者安息，凶手是 BryanWillman。”另一位匿名者发出了强烈警告。“请务必确认，” Anonymous|2252 写道。“这不仅仅关乎到一个人的性命，我们可以不负责任地向公众公布我们的结果，但却很可能有无辜的人会因此受到不应受到的对待。”

+ +

争论超过了一个小时。一些匿名者指出没有证据表明 Willman 曾经在弗格森警察局任过职。

+ +
Anonymous|3549：@gs 我们依旧没有证据能够证明 Bryan 曾在警局呆过
+ +
Intangir：现在的形势已经够紧张的了，一旦我们把这个消息公布出去，可能就会有人因此去杀了他
+ +
Anonymous|11057：唯一的证明方法是犯罪现场目击者报告。否则我们的结果只是一个谣言
+ +
Anonymous|11057：最快的排除嫌疑的方法是称他为嫌疑犯...我们都害怕犯下不公正的错误，但这种方法恰好可以避免这些...
+ +

大部分匿名者都反对在网上泄露他人信息。但是早晨七点左右匿名者们进行了一次投票。聊天记录显示，当时聊天室里有 80 人左右，只有不到十人参与了投票表决。因此他们决定在互联网上公布 Willman 的私人信息。

+ +
Anonymous|2252：还在 Twitter 上公布？
+ +
anondepp：lol
+ +
Anonymous|2252：用 @theanonmessage 公布？
+ +
TheAnonMessage：当然
+ +
TheAnonMessage：去发吧
+ +
anondepp：搞定了
+ +
Anonymous|2252：我去
+ +
TheAnonMessage：上帝保佑...
+ +
Anonymous|3549：...请拯救我们的灵魂
+ +
anondepp：lol
+ +

早晨 9 时 45 分，圣路易斯警察局对 TheAnonMessage 进行了答复。“Bryan Willman 从来没有在弗格森警察局或者圣路易斯警察局任过职，” 他们在 Twitter 上写道。“请不要再公布这位无辜市民的信息了。”（随后 FBI 对弗格森警察的电脑遭黑客入侵的事情展开了调查。）Twitter 管理员迅速封禁了 TheAnonMessage 的账户，但 Willman 的名字和家庭住址仍然被广泛传开。

+ +

实际上，Willman 是弗格森西郊圣安区的警察外勤负责人。当圣路易斯警察局的情报处打电话告诉 Willman，他已经被“确认”为凶手时，他告诉我，“我以为不过是个奇怪的笑话。”几小时后，他的社交账号上就收到了数百条要杀死他的威胁。他在警察的保护下，独自一人在家里呆了将近一个星期。“我只希望这一切都尽快过去，”他告诉我他的感受。他认为“匿名者”组织已经不可挽回地损害了他的名誉。“我不知道他们怎么会以为自己可以被再次信任的，”他说。

+ +

“我们并不完美，” OpFerguson 在 Twitter 上说道。“‘匿名者’组织确实犯错了，过去的几天我们制造一些混乱。为此，我们道歉。”尽管 Doyon 并不应该为这次错误的信息泄露攻击负责，但其他的匿名者却因为他发起了一次无法控制的行动，而归咎他。YourAnonNews 在 Pastebin 上发表了一则消息，上面写道，“你们也许注意到了组织不同的 Twitter 账户发表的话题 #Ferguson 和 #OpFerguson，这两个话题下的 Twitter 与信息是相互矛盾的。为什么会在这些关键话题上出现分歧，部分原因是因为 CommanderX 是一个‘想让自己出名的疯子/想让公众认识自己的疯子’——这种人喜欢，或者至少不回避媒体的宣传——并且显而易见的，组织内大部分成员并不喜欢这样。”

+ +

在个人 Twitter 上，Doyon 否认了所有关于“弗格森行动”的职责，他写道，“我讨厌这样。我不希望这样的情况发生，我也不希望和我认为是朋友的人战斗。”沉寂了几天后，他又再度获吹响了战斗的号角。他最近在 Twitter 上写道，“你们称他们是暴民，我们却称他们是压迫下的反抗之声”以及“解放西藏”。

+ +

Doyon 仍然处于藏匿状态。甚至连他的律师 Jay Leiderman 也不知道他在哪里。Leiderman 表示，除了在圣克鲁斯受到的指控，Doyon 很有可能因为攻击了 PayPal 和奥兰多而面临新的指控。一旦他被捕，所有的刑期加起来，他的余生就要在监狱里度过了。借鉴 Edward Snowden 的先例，他希望申请去俄罗斯避难。我们谈话时，他用一支点燃的香烟在他的公寓里比划着。“这里比他【哔~】的牢房强多了吧？我绝对不会出去，”他愤愤道。“我不会再联系我的家人了....这是相当高的代价，但我必须这么做，我会尽我的努力让所有人活得自由、明白。”

+![Check LVM Snapshot Space](http://www.tecmint.com/wp-content/uploads/2014/08/Check-LVM-Snapshot-Space.jpg) +检查LVM快照空间 + +让我们添加一些新文件到**tecmint_datas**里头。现在卷里大概有650MB左右的数据，而我我们的快照有1GB大。因此，有足够的空间在快照卷里备份我们的修改。这里我们可以使用下面的命令来查看到，我们的快照当前的状态。 + + # lvs + +![Check Snapshot Status](http://www.tecmint.com/wp-content/uploads/2014/08/Check-Snapshot-Status.jpg) +检查快照状态 + +你看到了，现在已经用掉了**51%**的快照卷，你要对你的文件作更多的修改都没有问题。使用下面的命令来查看更多详细信息。 + + # lvdisplay vg_tecmint_extra/tecmint_data_snap + +![View Snapshot Information](http://www.tecmint.com/wp-content/uploads/2014/08/Snapshot-Information.jpg) +查看快照信息 + +再来对上面图片中高亮的要点作个清楚的说明。 + +- 快照逻辑卷名称。 +- 当前使用的卷组名。 +- 读写模式下的快照卷，我们甚至可以挂载并使用该卷。 +- 快照创建时间。这个很重要，因为快照将跟踪此时间之后的每个改变。 +- 该快照属于tecmint_datas逻辑卷。 +- 逻辑卷在线并可用。 +- 我们录制快照的源卷大小。 +- 写时复制表大小，Cow = copy on Write，这是说对tecmint_data卷所作的任何改变都会写入此快照。 +- 当前使用的快照大小，我们的tecmint_data有10GB，而我们的快照大小是1GB，这就意味着我们的数据大概有650MB。所以，如果tecmint_datas中的文件增长到2GB，现在的51%中的内容将增加到超过所分配的快照的大小，当然，我们在创建快照时会出现问题。这就意味着我们需要扩展逻辑卷大小（快照逻辑卷） +- 给出快照组块的大小。 + +现在，让我们复制超过1GB的文件到**tecmint_datas**。让我们看看会发生什么。如果你那么做了，你将会见到‘**Input/output error**’这样的错误信息，它告诉你快照超出空间大小了。 + +![Add Files to Snapshot](http://www.tecmint.com/wp-content/uploads/2014/08/Add-Files-to-Snapshot.jpg) +添加文件到快照 + +如果逻辑卷满了，它就会自动下线，我们就不能再使用了，就算我们去扩展快照卷的大小也不行。最好的方法就是在创建快照时，创建一个和源一样大小的快照卷。**tecmint_datas**的大小是10GB，如果我们创建一个10GB大小的快照，它就永远都不会像上面那样超载，因为它有足够的空间来录制你的逻辑卷的快照。 + +#### 步骤2： 在LVM中扩展快照 #### + +如果我们需要在超载前扩展快照大小，我们可以使用以下命令来完成此项任务。 + + # lvextend -L +1G /dev/vg_tecmint_extra/tecmint_data_snap + +现在，那里有总计2GB大小的快照空间。 + +![Extend LVM

+ # lvs + +![Check Size of Snapshot](http://www.tecmint.com/wp-content/uploads/2014/08/Check-Size-of-Snapshot.jpg) +检查快照大小 + +然而，如果你的快照大小和源卷一样，我们就没有必要担心这些问题了。 + +#### 步骤3： 恢复快照或合并 #### + +要恢复快照，我们首先需要卸载文件系统。 + + # unmount /mnt/tecmint_datas/ + +![Un-mount File System](http://www.tecmint.com/wp-content/uploads/2014/08/Unmount-File-System.jpg) +卸载文件系统 + +只想检查挂载点是否卸载，可以使用下面的命令。 + + # df -h + +![Check File System Mount Points](http://www.tecmint.com/wp-content/uploads/2014/08/Check-Mount-Points.jpg) +检查文件系统挂载点 + +这里，我们的挂载已经被卸载，所以我们可以继续恢复快照。要恢复快照，可以使用**lvconvert**命令。 + + # lvconvert --merge /dev/vg_tecmint_extra/tecmint_data_snap + +![Restore LVM Snapshot](http://www.tecmint.com/wp-content/uploads/2014/08/Restore-Snapshot.jpg) +恢复LVM快照 + +在合并完成后，快照卷将被自动移除。现在我们可以使用**df**命令来查看分区大小。 + + # df -Th + +![Check Size of Snapshot](http://www.tecmint.com/wp-content/uploads/2014/08/Check-Snapshot-Space.jpg) + +在快照卷自动移除后，你可以用下面的命令查看逻辑卷大小。 + + # lvs + +![Check Size of Logical Volume](http://www.tecmint.com/wp-content/uploads/2014/08/Check-Size-of-LV.jpg) +检查逻辑卷大小 + +**重要**：要自动扩展快照，我们可以通过修改配置文件来进行。对于手动扩展，我们可以使用lvextend。 + +使用你喜欢的编辑器打开lvm配置文件。 + + # vim /etc/lvm/lvm.conf + +搜索单词autoextend。默认情况下，该值和下图中的类似。 + +![LVM Configuration](http://www.tecmint.com/wp-content/uploads/2014/08/LVM-Configuration.jpg) +LVM配置 + +修改此处的**100**为**75**，这样自动扩展的起始点就是**75**，而自动扩展百分比为20，它将自动扩容**百分之20**。 + +如果快照卷达到**75%**，它会自动为快照卷扩容**20%**。这样，我们可以自动扩容了。使用**wq!**来保存并退出。 + +这将把快照从超载下线中拯救出来，这也会帮助你节省更多时间。LVM是我们扩容以及获得其它众多特性如精简资源调配、拆卸、虚拟卷和使用精简池的唯一方法，让我们在下一个话题中来讨论吧。 + +-------------------------------------------------------------------------------- + +via:

+如果你一直在考虑如何加密电子邮件，那么在众多的邮件服务和邮件客户端中挑来挑去一定是件头痛的事情．可以考虑两种加密方法：SSL或TLS加密会保护发送到邮件服务器的登录名和密码．[Gunpg][1]是一款标准有用的Linux加密工具，可以加密和认证消息．如果你可以管理自己的GPG加密，并不考虑第三方工具，那它就够了，其它的我们将在稍后讨论． + +即便加密了消息，你仍然会暴露在流量分析中，因为消息头部必须是明文形式．所以需要另一款比如[Tor network][2]来隐藏你在互联网上的足迹．我们会看看各种邮件服务和客户端，以及其中的利弊． + +### 忘掉Web邮件 ### + +如果你使用过GMail, Yahoo，Hotmail或者其它Web邮件提供商的邮件服务，那就忘掉它们吧．你在Web浏览器里输入的任何信息都会暴露在JavaScript攻击中，而且无论服务提供商提供什么保障都是过眼云烟(译者注:此说法靠谱否?)．GMail,Yahoo和Hotmail均提供SSL/TLS加密来防止消息被窃听．但是它们不会提供任何保护来阻碍它们自己的数据挖掘，因此并不会提供端到端的加密．Yahoo和Google都声称将在明年推出端到端的加密．对此我持怀疑态度，因为如果一旦它们的核心业务数据挖掘受到干预，它们就什么都干不了了． + +市面上也有各式各样的声称可以为所有类型的电子邮件都能提供安全加密的第三方邮件加密服务，比如[Virtru][3]和[SafeMess][4]．对此我依旧表示怀疑，因为无论是谁，只要持有加密秘钥就可以访问你的消息，所以你还是要依赖于可信而不是技术． + +对等消息可以避免许多使用集中化服务中的缺陷．[RetroShare][5]和[Bitmessage][6]是两种流行的范例．我不知道它们是否如实所述，但这么说肯定由可取之处． + +那Anddroid和iOS又如何呢?假设大部分的Android和iOS应用都没有权限获取你的消息的话，那就是最安全的．不要照搬我说的 --

+也有许多加密电子邮件服务声称可以保护你的隐私．认真阅读细则，查看红色标注的地方，比如受限的用户数据采集，与好友分享，与执法部门的合作等．这些条款暗示它们会收集和共享用户数据，拥有权限获取你的加密秘钥，并读取你的消息． + +### Linux邮件客户端 ### + +一款独立的开源邮件客户端，比如, Mutt, Claws, Evolution, Sylpheed和Alpine，可建立你自己控制的GnuPG秘钥，给你大部分的保护．（建立更安全的电子邮件和Web浏览的最容易的方式是运行TAILS　live的Linux发行版．详情查看[Protect Yourself Online With Tor, TAILS, and Debian][8].） + +无论你使用的是TAILS还是一款标准Linux发行版，管理GnuPG的方法是相同的，所以下面来学习如何使用GnuPG加密消息． + +### 使用GnuPG ### + +首先，熟悉一下相关术语。OpenPGP是一种开放的电子邮件加密和认证协议，基于菲利普·齐默曼的Pretty Good Privacy (PGP)。GNU Privacy Guard (GnuPG or GPG)是OpenPGP的GPL实现。GnuPG使用对称公钥加密算法，也就是说会生成一堆密钥：一个任何人都可以用来加密发送给你的消息的公钥和一个只有你自己拥有用来解密消息的的私钥。GnuPG执行两个分开的函数：数字化签名消息以证明消息来自你和加密消息。任何人都可以读到你的数字签名消息，但只有那些与你交换密钥的人才可以读取加密消息。切记千万不要与他人分享你的密钥！只能分享公钥。 + +Seahorse是GnuPG对应的GNOME图形化前端，KGpg是KDE图形化的GnuPG工具。 + +现在我们执行生成和管理GunPG密钥的基本步骤。这个命令生成一个新的密钥： + + $ gpg --gen-key + +这个过程有许多步骤；对于大部分人来说，只需要回答所有的问题，遵循默认设置就好。当你生成你的密钥时，记下来并将其保存在一个安全的地方，因为如果你丢掉了它，你就不能解密任何消息了。任何关于不要写下密码的建议都是错误的。我们中的大部分人要记住许多登录名和密码，包括那些我们几乎从来不会用到的，所以全部记住它们是不现实的。你知道当人们不写下他们的密码时会发生什么吗？他们会选择生成简单的密码并不断重复使用。你存储在电脑里的任何东西都潜在地会被攻击窃取；一个保存在上锁的柜子里的小本是无法通过渗透获取的，除了物理的入侵，当然入侵者要知道如何去寻找它。 + +我必须叮嘱你们去弄清楚如何使用新密钥去配置邮件客户端，因为每一个都不同。你可以按照如下操作列出你的密钥： + + $ gpg --list-keys + /home/carla/.gnupg/pubring.gpg + ------------------------------ + pub 2048R/587DD0F5 2014-08-13 + uid Carla Schroder (my gpg key) + sub 2048R/AE05E1E4 2014-08-13 + +这能快速地获知像密钥的位置、名称（也就是UID）等必要信息。假设你想要把公钥上传到密钥服务器，可以参考实例操作： + + $ gpg --send-keys 'Carla Schroder' --keyserver http://example.com + +当你为上传到公钥服务器生成了一个新的密钥，你也应该生成一个撤销证书。不要推迟到以后做———当你生成新密钥时就生成它。你可以给它取任意的名称，比如使用一个像mycodeproject.asc的描述性名称来代替revoke.asc： + + $ gpg --output revoke.asc --gen-revoke 'Carla Schroder' + +如果你的密钥缺乏抵抗力，你可以通过向keyring导入撤销证书来撤销它： + + $ gpg --import ~/.gnupg/revoke.asc + +然后生成并上传一个新的密钥来取代它。当它们更新到密钥数据库时，所有使用旧密钥的用户都会被通知。 + +你必须像保护私钥一样保护撤销证书。将它拷贝到CD或USB存储器中，并加锁，然后从电脑中删除。这是明文密钥，所以你甚至可以将它打印出来。 + +如果你需要一份复制粘贴的密钥，比如在允许将密钥粘贴到网页表格中的公用keyring中，或者是想将公钥发布到个人站点上，那么你必须生成一份公钥的ASCII-armored版本： + + $ gpg --output carla-pubkey.asc --export -a 'Carla Schroder' + +这会生成可见的明文公钥，就像下面这个小例子： + + -----BEGIN PGP

6，或者1-4，也可以一次将它们全部运行，输入1-16。大多数步骤需要‘y’，即yes，来确认，而下一个任务则等着你敲击回车来执行。在此期间，你有足够的时间来阅读安装指南，它可以通过ALT-g来打开。当然，你也可以出去溜达一圈再回来。 + +![](https://farm4.staticflickr.com/3868/15253227082_5e7219f72d_z.jpg) + +这16个步骤分成“基础安装”和“桌面安装”两组。第一个组安装主要关注本地化、分区，以及安装启动器。 + +安装器带领你穿越分区世界，你可以选择使用gparted、gdisk，以及cfdisk。 + +![](https://farm4.staticflickr.com/3873/15230603226_56bba60d28_z.jpg) +

+![](https://farm6.staticflickr.com/5560/15253610085_aa5a9557fb_z.jpg) + +安装完你喜爱的启动加载器后，第一部分安装就完成了，这大约需要花费12分钟。这是在普通的Arch Linux中你第一次重启进入系统所处之处。 + +在Lution的帮助下，继续进入第二部分，在这一部分中将安装Xorg、声音和图形驱动，然后进入桌面环境。 + +![](https://farm4.staticflickr.com/3918/15066917430_c21e0f0a9e_z.jpg) + +安装器会检测是否在VirtualBox中安装，并且会自动为VM安装并加载正确的通用驱动，然后相应地设置**systemd**。 + +在下一步中，你可以选择KDE、Gnome、Cinnamon、LXDE、Englightenment、Mate或XFCE作为你的桌面环境。如果你不喜欢臃肿的桌面，你也可以试试这些窗口管理器：Awesome、Fluxbox、i3、IceWM、Openbox或PekWM。 + +![](https://farm4.staticflickr.com/3874/15253610125_26f913be20_z.jpg) + +在使用Cinnamon作为桌面环境的情况下，第二部分安装将花费不到10分钟的时间；而选择KDE的话，因为要下载的东西多得多，所以花费的时间也会更长。 + +Lution-AIS在Cinnamon和Awesome上像个妩媚的小妖精。在安装完成并提示重启后，它就带我进入了我所渴望的环境。 + +![](https://farm4.staticflickr.com/3885/15270946371_c2def59f37_z.jpg) + +我要提出两点非议：一是在安装器要我选择一个镜像列表时，另外一个是在创建fstab文件时。在这两种情况下，它都另外开了一个终端，给出了一些文本信息提示。这让我花了点时间才搞清楚，原来我得把它关了，安装器才会继续。在创建fstab后，它又会提示你，而你需要关闭终端，并在问你是否想要保存文件时回答‘是’。 + +![](https://farm4.staticflickr.com/3874/15067056958_3bba63da60_z.jpg) + +我碰到的第二个问题，可能与VirtualBox有关了。在启动的时候，你可以看到没有网络被检测到的提示信息。点击顶部左边的图标，将会打开wicd，这里所使用的网络管理器。点击“断开”，然后再点击“连接”并重启安装器，就可以让它自动检测到了。 + +Evo/Lution我以为是个有价值的项目，在这里Lution工作一切顺利，目前还没有什么可告诉社区的。他们开启了一个全新的网站、论坛和维基，需要填充内容进去啊。所以，如果你喜欢这主意，加入[他们的论坛][3]并告诉他们吧。本文中的ISO镜像可以从[此网站][4]下载。 +

+### 步骤4： DNSMASQ服务器排障并在系统范围内启用 ### + +**9.** 要诊断服务器以查询最终是否发生问题或要查询其它提供给客户端的信息，运行以下命令来打开日志文件。 + + # tailf /var/log/daemon.log + +![Debug DNSMASQ Server](http://www.tecmint.com/wp-content/uploads/2014/09/Debbug-DNSMASQ-Server.png) + +DNSMASQ服务器排障 + +**10.** 如果服务器测试中已一切就绪，你现在可以在**sysv-rc-conf**包的帮助下，启用**DNSMASQ**守护进程自启动，以使该进程在系统重启后自动启动。 + + # apt-get install sysv-rc-conf + # sysv-rc-conf dnsmaq on + +![Enable DNSMASQ Daemon](http://www.tecmint.com/wp-content/uploads/2014/09/Enable-DNSMASQ-Daemon.png) + +启用DNSMASQ守护进程 + +到此为止吧！现在你的**PXE**服务器已经整装待发，随时准备好分配IP地址了（**DHCP**），并为你所有网段中的客户端提供需要的启动信息，这些信息配置用来从网络启动并安装Debian Wheezy。 + +使用PXE网络启动安装在服务器主机数量增长时很有优势，因为你可以在短时间内火同时设置整个网络基础架构，为版本升级提供了方便，也可以通过kickstart文件使整个安装的全自动化。 +

+logrotate是个十分有用的工具，它可以自动对日志进行分解（或轮循）、压缩以及删除旧日志文件。例如，你可以设置logrotate，让/var/log/foo日志文件每30天轮循，并删除超过6个月的日志。配置完后，logrotate的运作完全自动化，不必进行任何进一步的认为干预。另外，旧日志也可以通过电子邮件发送，不过该选项超出了本教程的讨论范围。 + +主流Linux发行版上都默认安装有logrotate包，如果出于某种原因，logrotate没有出现在里头，你可以使用apt-get或yum命令来安装。 + +在Debian或Ubuntu上： + + # apt-get install logrotate cron + +在Fedora，CentOS或RHEL上： + + # yum install logrotate crontabs + +logrotate的配置文件是/etc/logrotate.conf，通常不需要对它进行修改。日志文件的轮循设置在独立的配置文件中，它（们）放在/etc/logrotate.d/目录下。 + +### 样例一 ### + +在第一个样例中，我们将创建一个10MB的日志文件/var/log/log-file。我们将展示怎样使用logrotate来管理该日志文件。 + +我们从创建一个日志文件开始吧，然后在其中填入一个10MB的随机比特流数据。 + + # touch /var/log/log-file + # head -c 10M < /dev/urandom > /var/log/log-file + +由于现在日志文件已经准备好，我们将配置logrotate来轮循该日志文件。让我们为该文件创建一个配置文件。 + + # vim /etc/logrotate.d/log-file + +---------- + + /var/log/log-file { + monthly + rotate 5 + compress + delaycompress + missingok + notifempty + create 644 root root + postrotate + /usr/bin/killall -HUP rsyslogd + endscript + } + +这里： + +- **monthly**: 日志文件将按月轮循。其它可用值为‘daily’，‘weekly’或者‘yearly’。 +- **rotate 5**: 一次将存储5个归档日志。对于第六个归档，时间最久的归档将被删除。 +- **compress**: 在轮循任务完成后，已轮循的归档将使用gzip进行压缩。 +- **delaycompress**: 总是与compress选项一起用，delaycompress选项指示logrotate不要将最近的归档压缩，压缩将在下一次轮循周期进行。这在你或任何软件仍然需要读取最新归档时很有用。 +- **missingok**: 在日志轮循其间，任何错误将被忽略，例如“文件无法找到”之类的错误。 +- **notifempty**: 如果日志文件为空，轮循不会进行。 +- **create 644 root root**: 以指定的权限创建全新的日志文件，同时logrotate也会重命名原始日志文件。 +- **postrotate/endscript**: 在所有其它指令完成后，postrotate和endscript之间指定的命令将被执行。在这种情况下，rsyslogd 进程将立即再次读取其配置并继续运行。 + +上面的模板是通用的，而配置参数则根据你的需求进行调整，不是所有的参数都是必要的。 + +### 样例二 ### + +在本例中，我们只想要轮循一个日志文件，然而日志文件大小会增长到50MB。 + + # vim /etc/logrotate.d/log-file + +---------- + + /var/log/log-file { + size=50M + rotate 5 + create 644 root root + postrotate + /usr/bin/killall -HUP rsyslogd + endscript + } + +### 样例三 ### + +我们想要让旧日志文件以创建日期命名，这可以通过添加dateext常熟实现。 + + # vim /etc/logrotate.d/log-file + +---------- + + /var/log/log-file { + monthly + rotate 5 + dateext + create 644 root root + postrotate + /usr/bin/killall -HUP rsyslogd + endscript + } + +这将导致归档文件在它们的文件名中包含日期信息。 + +### 排障 ### + +这里提供了一些logrotate设置的排障提示。 + +#### 1. 手动运行logrotate #### + +**logrotate**可以在任何时候从命令行手动调用。 + +要调用为/etc/lograte.d/下配置的所有日志调用**logrotate**： + + # logrotate /etc/logrotate.conf + +要为某个特定的配置调用logrotate： + + # logrotate /etc/logrotate.d/log-file + +#### 2. 演练 #### + +排障过程中的最佳选择是使用‘-d’选项以预演方式运行logrotate。要进行验证，不用实际轮循任何日志文件，可以模拟演练日志轮循并显示其输出。 + + # logrotate -d /etc/logrotate.d/log-file + +![](https://farm6.staticflickr.com/5561/15096836737_33d3cd1ccb_z.jpg) + +正如我们从上面的输出结果可以看到的，logrotate判断该轮循是不必要的。如果文件的时间小于一天，这就会发生了。 + +#### 3. 强制运行 #### + +即使轮循条件没有满足，我们也可以通过使用‘-f’选项来强制logrotate轮循日志文件，‘-v’参数提供了详细的输出。 + + # logrotate -vf /etc/logrotate.d/log-file + +---------- + + reading config file /etc/logrotate.d/log-file + reading config info for /var/log/log-file + + Handling 1 logs + + rotating pattern: /var/log/log-file forced from command line (5 rotations) + empty log files are rotated, old logs are removed + considering log /var/log/log-file + log needs rotating + rotating log /var/log/log-file, log->rotateCount is 5 + dateext suffix '-20140916' + glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]' + renaming /var/log/log-file.5.gz to /var/log/log-file.6.gz (rotatecount 5, logstart 1, i 5), + old log /var/log/log-file.5.gz does not exist + renaming /var/log/log-file.4.gz to /var/log/log-file.5.gz (rotatecount 5, logstart 1, i 4), + old log /var/log/log-file.4.gz does not exist + . . . + renaming /var/log/log-file.0.gz to /var/log/log-file.1.gz (rotatecount 5, logstart 1, i 0), + old log /var/log/log-file.0.gz does not exist + log /var/log/log-file.6.gz doesn't exist -- won't try to dispose of it + renaming /var/log/log-file to /var/log/log-file.1 + creating new /var/log/log-file mode = 0644 uid = 0 gid = 0 + running postrotate script + compressing log with: /bin/gzip + +#### 4. Logrotate记录日志 #### + +logrotate自身的日志通常存放于/var/lib/logrotate/status目录。如果处于排障目的，我们想要logrotate记录到任何指定的文件，我们可以指定像下面这样从命令行指定。 + + # logrotate -vf –s /var/log/logrotate-status /etc/logrotate.d/log-file + +#### 5. Logrotate定时任务 #### + +logrotate需要的**cron**任务应该在安装时就自动创建了，我把cron文件的内容贴出来，以供大家参考。 + + # cat /etc/cron.daily/logrotate + +---------- + + #!/bin/sh + + # Clean non existent log file entries from status file + cd /var/lib/logrotate + test -e status || touch status + head -1 status > status.clean + sed 's/"//g' status | while read logfile date + do + [ -e "$logfile" ] && echo "\"$logfile\" $date" + done >> status.clean + mv status.clean status + + test -x /usr/sbin/logrotate || exit 0 + /usr/sbin/logrotate /etc/logrotate.conf + +小结一下，logrotate工具对于防止因庞大的日志文件而耗尽存储空间是十分有用的。配置完毕后，进程是全自动的，可以长时间在不需要人为干预下运行。本教程重点关注几个使用logrotate的几个基本样例，你也可以定制它以满足你的需求。 + +希望本文对你有所帮助。 +

+假设由于某种原因，你需要嗅探HTTP站点的流量（如HTTP请求与响应）。举个例子，你可能在测试一个web服务器的实验性功能，或者　你在为某个web应用或RESTful服务排错，又或者你正在为PAC排错或寻找某个站点下载的恶意软件。不论什么原因，在这些情况下，进行HTTP流量嗅探对于系统管理、开发者、甚至最终用户来说都是很有帮助的。 +

+如果你下载了httpry的源码，你会发现源码下有一系Perl脚本，这些脚本用于分析httpry输出。脚本位于目录httpry/scripts/plugins。如果你想写一个定制的httpry输出分析器，则这些脚可以作为很好的例子。其中一些有如下的功能： + +- **hostnames**: 显示唯一主机名列表. +- **find_proxies**: 探测web代理. +- **search_terms**: 查找及计算输入检索服务的检索词。 +- **content_analysis**: 查找含有指定关键的URL。 +- **xml_output**: 将输出转换为XML形式。 +- **log_summary**: 生成日志摘要。 +- **db_dump**: 将日志文件数据保存数据库。 + +在使用这些脚本之前，首先使用'-o'选项运行httpry。当获取到输出文件后，立即使用如下命令执行脚本： + + $ cd httpry/scripts + $ perl parse_log.pl -d ./plugins + +你可能在使用插件的时候遇到警告。比如，如果你没有安装带有DBI接口的MySQL数据库那么使用db_dump插件时可能会失败。如果一个　插件初始化失败的话，那么这个插件不能使用。所以你可以忽略那些警告。 + +当parse_log.pl完成后，你将在httpry/scripts 目录下看到数个分析结果。例如，log_summary.txt 与如下内容类似。 + +![](https://farm4.staticflickr.com/3845/14799162189_b85abdf21d_z.jpg) + +总结，当你要分析HTTP数据包的时候，httpry非常有用。它可能并不被大多Linux使用着所熟知，但会用总是有好处的。你对这个工具有什么看法呢？ +
