近來在試 Google Web Toolkit (GWT)，為了這個要裝 Tomcat 。數天前說過，Ubuntu 可以 apt-get Tomcat 。但後來發現，那個 Tomcat 跑不到 GWT Sample 的 war 。
後來，到 Apache 官網下載 Tomcat 去跑，跑 war 卻 ok 。

tomcat
起初，我還以為 tomcat 是需要 Apache 才能跑。原來這兩個東東可以是完全沒有關係。
Ubuntu apt-get 提供了 tomcat 。但奇怪的是， Ubuntu 的 wiki page 卻叫你去官網下載。另外， Ubuntu tomcat 在安裝時，會告訴你依靠 gcj ，這點也叫人不安。
不過，其實使用 Ubuntu-tomcat ，其實不是想像中那麼可怕。
https://help.ubuntu.com/9.04/serverguide/C/tomcat.html
要注意的是，只要修改 xml 檔，就能使 tomcat 使用 sun-java 。

安裝Java
sudo apt-get install sun-java6-jdk
ref: http://wiki.ubuntu.org.cn/Java%E5%AE%89%E8%A3%85%E9%85%8D%E7%BD%AE
預設文件路徑
當 Ubuntu 以中文環境安裝時，資料夾的名字會以中文命名，但這個很不好。這個不但用起來麻煩，而且程式也未必能支持。最好的解決辦法，就是改變資料夾的路徑。
資料夾的路徑設定，放在以下的地方：
~/.config/user-dirs.dirs

安裝Flash player
sudo apt-get install flashplugin-nonfree
ref: http://www.cyberciti.biz/faq/ubuntu-linux-how-to-install-flash-player-for-firefox/
Youtube小測之一：
比起我當初在8.10情況暢順得多。CPU在800MHz程度下約80%。
Youtube小測之二：
這是800MHz的狀況，速度慢得很可憐。雖然在1.87GHz時情況會有點改善，但不久不知為何電腦會自動跳回800MHz，可能是和過熱有關？
另，就像這個網頁放上兩個Youtube沒有play，甚至沒有顯示這個網頁tab也好，也可以使我的電腦耗上20%的CPU，奇怪。
安裝Droid字型
ref: http://playubuntu.blogspot.com/2008/01/googledroid.html
很遺憾地， DroidSansFallback 不支持 monospace 。
話說，為甚麼新增字型要搞這麼多步驟？真叫人想不明白。
安裝倉頡輸入法
sudo apt-get install scim-tables-zh
另外，很奇怪地， SCIM 標點半/全形轉換的 hotkey ， Ctrl-period ，不能正常運作。

後記：重新login後，按鍵正常了。奇怪。
