安装 git：
Linux:
sudo apt-get install git-svn
Windows:
http://code.google.com/p/msysgit/
1.在本地创建
mkdir new_repository
cd new_repository
git init-db
2.从已存在的Repository获取
git clone /path/to/exist/repository
3.在远程服务器上创建bare repository
$ ssh myserver.com Welcome to myserver.com! $ mkdir /var/git/myapp.git && cd /var/git/myapp.git $ git –bare init Initialized empty Git repository in /var/git/myapp.git $ exit Bye!
4.在本地添加远程repository并push
$ cd ~/Sites/myapp $ git remote add origin ssh://myserver.com/var/git/myapp.git $ git push origin master
5.使用ssh从远程服务器上获取文件
git clone ssh://user@myserver.com/var/git/myapp.git
git add /path/to/filename # 添加单个文件
git add filename [filename] # 添加多个文件
git add /path/to/directory # 添加文件夹
git add ./ # 添加当前文件夹
提交文件
1.提交本地更新
git commit -m “commit message is here”
OR
git commit -a -m “commit message is here”
2.提交更新至远端
git push /path/to/repository
更新文件
1.更新本地工作目录文件
git checkout -f
2.更新远端文件
git pull /path/to/repository
创建分支
创建自己的工作分支,以避免对Master Branch 的影响
git branch raecoo # 成功创建了名为raecoo的分支
git checkout raecoo # 将当前工作切换至raecoo分支
git-branch -D branch-name
合并分支
git checkout master # 切换当前分支到master
git merge “merge message is here” HEAD raecoo # 将raecoo分支与master分支合并
OR
git checkout master #效果与上相同
git pull . raecoo

从今天起，P1.CN 开发团队又增加了1名Ruby on Rails Developer。P1 Groups 即将推出，敬请期待更精彩的P1, 更稳定的服务。
又看到Tangos写了一篇关于Virtual World的Blog，于是心血来潮试用了一下虚拟世界Hipihi和Novoking. 体验不是一般的差。
下载安装了HiPiHi_world_50021，进入后不能容忍粗劣的画面和慢动作。找了一圈只发现有17个人在线（周六下午），根本找不到人交流。于是退出并卸载了程序。
Novoking 0.94 beta 版的画面和行走体验都要HiPiHi好多了，登录后，穿着短库在里面跑了5分钟，终于找到了时装店，由于操作的不灵便，花了15分钟才晕晕的买到一身服装。里面也就没人可以交流。
而我之前体验过网络游戏，几乎任何一款网游都比Hipihi和Novoking做得要好，不管是人物的移动和画面的美观。
与其说 Hipihi 和 Novoking 是Web 2.0的社区，不如说是只有粗糙场景的3D游戏雏形。我本人非常看好这一类的社区产品，希望他们哪家能做好了，于是我到虚拟世界里去开个烤鸭店，或在Virtual World里卖麦当劳，然后送到现实人的手中，岂不是很好玩？
然而现在显然不行，还是要先做好产品。产品不好，再多的软文行销也是没用的。
