1. 在 linux console 下設定 proxy：
export http_proxy=”http://hostname:portnumber”
2. SD card (sdb1、sdb2) mount 完成後（假設 mount 在 /media/boot/ 和 /media/rootfs/ 下），將 foo.tar.bz2 解壓到 /media/rootfs/：
tar jxfv foo.tar.bz2 –C /media/rootfs
3. 將 foo.tar.gz 解壓到 /myfolderpath/
tar zxfv foo.tar.gz –C /myfolderpath/
4. check out SVN server 中第 38 個版本：
svn co –r 38 –username MYNAME –password PASSWORD svn://hostip/folder/subfolder
5. 搜尋 FOLDER 資料夾中含有關鍵字 KEYWORD 的檔案並標示行數：
grep –r –n “KEYWORD” FOLDER
6. 讓自己寫的 script 開機後自動執行：
/etc/profile.d/my_script.sh
7. universalIndentGUI => save config file => create batch file (config and batch files shoud be at the same directory)
8. Vim 中的長字串自動完成：ctrl-p 或 ctrl-n
9. Good to use 共用資料夾 in VirtualBox guest OS, it's easy and powerful.
10. shift + right click folder => open command here
11. in 64bit Win7, 32bit-chrome will download 32bit Java by default
12. MSN minimize to system tray => Vista Mode
13. gtags 好像只能在 WinXP 32bit 下面才能正常運作，Win7 x64 無法, 但是在Ubuntu下可以正常運作
14. Good to use easygui in Python
15. win7 刪除服務 sc delete servicename
16. virtualbox network bridge 不能用混合模式
17. mount box.net: https://www.box.net/dav
18. mkmmc-android.sh
