I like the default color of the GNOME terminal in Ubuntu 10.04 very much. So I record it at this lest I should modify it mindlessly.
color 1：#2E3436
color 2：#CC0000
color 3：#4E9A06
color 4：#C4A000
color 5：#3465A4
color 6：#75507B
color 7：#06989A
color 8：#D3D7CF
color 9：#555753
color 10：#EF2929
color 11：#8AE234
color 12：#FCE94F
color 13：#729FCF
color 14：#AD7FA8
color  15：#34E2E2

I'm used to add an icon link to open ssh or kermit terminal, and I want it's opened minimized.

The method is to type the command below at command column:

If you want to replace Evolution to Thunderbird in Ubuntu, you can add Thunderbird to Indicator Applet besides install Thunderbird.

Please refer to http://ubuntuforums.org/showthread.php?t=1439519

I use Ubuntu 10.04 for my PC, I just do:
1. Install Thunderbird via Ubuntu Software Center or Synaptic
2. Add the text
/usr/share/applications/thunderbird.desktop
to the new file "/usr/share/indicators/messages/applications/thunderbird"
3. Logout and login and then done

But this method is just to add the Thunderbird link into Indicator Applet, I want Thunderbird to display new mail notification.

So I use the extension "Gnome Integration" of Thunderbird to achieve it:
1. Install the extension "Gnome Integration" (https://addons.mozilla.org/en-US/thunderbird/addon/123887/)
2. In Gnome Integration Option, you can press the "Test" button to test this function.
3. If the error indicates the command "notify-send" isn't exist, please install "libnotify-bin" via Synaptic.

But I am not still satisfy with this, because the method I want likes Thunderbird in Windows can show the tray icon to point out how much mails unread, I will keep going to discovery new method to do this.

That article described three solutions.

I choice the second solution and it's worked fine.

The second method is:
1. Edit "/etc/fonts/conf.avail/49-sansserif.conf"
2. Modify the last
        <edit name="family" mode="append_last">
                <string>sans-serif</string>
        </edit>
to
        <edit name="family" mode="append_last">
                <string>sans serif</string>
        </edit>

3. That means to replace the dash to a space.

"php_exif.dll找不到指定的模組"的解決方法就是

修改php.ini，把extension=php_mbstring.dll放到extension=php_exif.dll之前就可以了

然後重啟Apache就完工啦~~


另外，要修改PHP execution time，修改php.ini裡的max_execution_time，預設是30秒

在Linux中有個指令可以令電腦的蜂鳴器響起來，那就是beep

這個程式可以透過套件安裝，也可以去作者的網頁去下載原始碼來編譯，其實稍微看了一下原始碼，發現要讓電腦發出聲音還真簡單阿~~

***好久沒發文了~有空就把知道的小技巧做個紀錄***

最近常有用Adobe Reader來看一些中文的雜誌，再加上家裡的電腦螢幕是寬螢幕的，所以我通常都會用"連續雙欄"的顯示方式來閱讀，如果閱讀的是外文的電子書或雜誌，因為這類的實體書籍通常都是"由左至右"的文字格式，所以在這種"連續雙欄"的顯示方式閱讀起來沒有太大問題，而起看起來跟實體書籍的感覺一樣。

但是大部分中文書籍或是雜誌的文字卻是屬於"由右至左"的格式，一般Adobe Reader預設的"連續雙欄"的顯示方式會使得左右兩頁的文章顛倒，閱讀起來完全跟實體書籍不同，而且有些跨頁面的顯示也會很奇怪，所以這裡提供一個小技巧可以幫助這些"由右至左"格式的電子書看起來跟實體書籍一樣：

在【編輯】→【偏好設定...】中的【國際】選項，裡面有個【預設閱讀方向】的選單可以選，要閱讀右開格式的電子書就選擇【由右至左】，然後確定再從開文件既可。

在之前的文章Ubuntu 9.04 install note中有提到去修改Vim的設定，讓Vim更好用。

過去有時候要知道現在編輯的檔案名稱或檔案的長度，都要下指令去顯示，但現在我又在Vim中加入status bar，讓Vim可以顯示更多資訊，使得Vim更好用，之前的問題也就沒有了，唯一的缺點就是這個status bar會佔去一列的空間，不過這還可以接受。

在Vim的設定檔/etc/vim/vimrc中，加入以下的code，就可以產生如下圖的效果：

set laststatus=2
set statusline=File:\ %m%<%f\%r%h%w\ [%{&ff},%{&fileencoding},%Y]%=\ [ASCII=\%03.3b]\ [Hex=\%02.2B]\ [Pos=%l,%v,%p%%]\ [Total\ Line=%L]


至於這兩行code的意義，請自行參考Vim的文件Vim documentation
