1. 比照 external 內的資料夾,新增一個 project folder ,內容比照辦理。
2. 進入 device 資料夾,加入新的 application 定義
3. 可參考內建程式:tinymix, tinycap, tinyplay…
「象牙塔」一詞源於聖經,所羅門王用這個詞形容他愛人的脖子。十九世紀法國詩人用「生活在象牙塔裡」來形容括科學家和藝術家,他們非常專注從事其專業工作,不受外力的干擾,也不費心思去注意外界的事情。「象牙塔」一詞演變下來,也有了一點負面的含意,暗指一個知識分子,生活在孤立隔絕的環境中,不知道也不關心外面的事情,脫離了現實,不食人間煙火。(摘錄自劉炯朗部落格「我愛談天你愛笑」)
「象牙窟」紀錄了一位塵世間迷途小小工程師的所學所聞,也分享給有興趣的朋友們。IT之路雖然辛苦,也很迷人,常常一不小心就深陷問題的泥沼無法自拔,或是瞻仰著大師的傑作感動不已。「象牙」之意在於提醒自己多留點時間活在現實世界,「窟」則表示所學貧乏不足為塔,需再努力。

話說我的工作內容需要大量使用 SSH 來存取 virtual machine,但是 putty 一次一個視窗、要加 X11 forward 還要外掛,很是不便。
幸好給我找到這個軟體:MobaXterm
裡面幾乎整額所有我需要的功能:SSH、SFTP、RDP、X11 forwarding、多頁面視窗、還有很多像是 gvim 的外掛可以加。
難得讓我一看就覺得不可思議的好作品!
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
