分布式控制系统代码托管社区

　　GitHub可以托管各种git库，并提供一个web界面，但与其它像 SourceForge或Google
Code这样的服务不同，GitHub的独特卖点在于从另外一个项目进行分支的简易性。为一个项目贡献代码非常简单:首先点击项目站点的“fork”的按
钮，然后将代码检出并将修改加入到刚才分出的代码库中，最后通过内建的“pull request”机制向项目负责人申请代码合并。

　　Git的优势

　　Git是一个分布式的版本控制系统，最初由Linus
Torvalds编写，用作Linux内核代码的管理。在推出后，Git在其它项目中也取得了很大成功，尤其是在Ruby社区中。目前，包括Rubinius和Merb在内的很多知名项目都使用了Git。Git同样可以被诸如Capistrano和Vlad
the Deployer这样的部署工具所使用。

　　Git的成就

　　目前已拥有超过160万注册用户，代码库达280万个。个人代码托管服务为每月7美元，带有防火墙的企业托管服务则需要每月至少5000美元。大型科技公司在购买GitHub服务方面的开支每年高达100万美元。

　　除了命令式的库浏览器和一个项目Wik，GitHub甚至还包括了一个GitHub gem，以使通过shell方式使用GitHub更为方便。

GitHub can host various git libraries and provide a web interface, but with others such as SourceForge or Google

Unlike services like Code, the unique selling point of GitHub is the ease of branching from another project. Contributing code to a project is very simple: first click the “fork” button on the project site

Button, then check out the code and add the changes to the code base you just separated, and finally apply for code merging from the project leader through the built-in “pull request” mechanism.

Advantages of Git

Git is a distributed version control system originally developed by Linus

Written by Torvalds and used as the management of Linux kernel code. Since its launch, Git has also achieved great success in other projects, especially in the Ruby community. Currently, Git is used in many well-known projects, including Rubinius and Merb. Git can also be used by people such as Capistrano and Vlad

Used by deployment tools such as the Deployer.

The achievements of Git

At present, it has more than 1.6 million registered users and 2.8 million code bases. A personal code hosting service costs $7 a month, while an enterprise hosting service with a firewall costs at least $5000 a month. Large technology companies spend as much as $1 million a year on GitHub services.

In addition to the imperative library browser and a project Wik,GitHub, it even includes a GitHub gem to make it easier to use GitHub through shell.
