How to PAUSE and CONTINUE a Linux process
Use kill command to send -STOP signal to pause a process and -CONT signal to continue it.
Example on CentOS6 Desktop:
1. Open a Terminal (name as T1) on Desktop and send "ps -aux | grep bash" to see how much bash in there.
2. Open another Terminal (name as T2) on Desktop and on T1 send "ps -aux | grep bash" to see process id of new created bash (T2)
3. On T1, send "kill -STOP" to pause T2
>T2 is hang
4. On T1, send "kill -CONT" to continue T2
>T2 is back to work
This is useful if a script is running on T2 and you want to pause it and continue it later

Docker on Windows
Docker
目前只支援在Ubuntu下跑，若要在Windows下，可用VirtualBox搭配Vagrant使用
官方Install Document
1.首先把VirtualBox和Vagrant安裝起來
2. git clone docker and vagrant up
3. 用putty登入127.0.0.1:2222
(ubuntu vm的port 22被vagrant自動bind到host的port 2222)
default user/password 是 vagrant/vagrant
4. 登入後 基本使用教學
5. 之後就是在container的環境了，用apt-get可以安裝軟體，Alt+P & Alt+Q sequence可以跳回host(ubuntu vm)而不會結束container，跳host之後可用docker attach回去。
6. docker ps查看還在跑的container資訊，包括ID和port(docker run時用-p參數)，docker ps -a可看全部
7. docker commit 可存下container成image，例如新安裝的軟體，方便下次直接run成新的container
8. 編寫Dockerfile可build新的image
9. docker images查看現在有的images
10. 若要讓vagrant bind ubuntu vm的port給host，在vagrant up之前要先set FORWARD_DOCKER_PORTS=True
(好像沒辦法正常up起來)

docker run -t -i ubuntu /bin/bash跑ubuntu這個image，產生一個container，執行/bin/bash並進入interactive shell

Subversion, TortoiseSVN 介紹
Subversion(svn)是個很有名的revision control system，在許多open source專案都有被使用到，在協同工作的環境中(個人使用也可以)，幫助管理檔案的版本，也可回復到之前的版本，方便追蹤軟體或文件的開發過程。Subversion是個集中式的管理機制，大部分的動作都需要與repository連線來完成，所以若是repository不正常或其他原因無法access到就不能做svn的操作了(Git可以)，算是svn的缺點。
TortoiseSVN是一隻Subversion的GUI Client程式，可以方便使用者操作svn而不需要透過command line的方式，但前提是使用者還是必須對svn的各個操作有所認識才行。TortoiseSVN也整合了Office的文件，可以做版本差異的比對，方便解決conflict。
一般svn的convention(慣例)是在project的repository下建立三個directory分別是/trunk, /branches, /tags。/trunk裡面放main line of development，後續可merge進其他的branch進來。/branches裡面放各個branch，一個branch取一個directory名子，通常是從/trunk branch(svn copy)進來這裡。/tags裡面放各版的release版本，和branches directory類似，只是通常就是定版了，不會再commit或merge新的東西進來。
一般操作流程
1. Check Out一個project
2. 編輯內容(新增一個功能或是修正bug)
3. Update
4. Commit
若是要先branch，完成後再merge進trunk
1. Branch: svn copy path/trunk path/branches/feature01
2. 在path/branches/feature01做修改
3. Update & Commit
4. Merge: 先cd到path/trunk在svn merge path/branches/feature01
