雨
又一個訓唔著既晚上。唔同既係,今晚有雷雨上映。
狂風首先響起左前奏, 雨聲令我既注意力再度分散, 走左出去露台觀雨。雨似雨, 又不似雨。初聽之下,雨聲就是雨聲, 突然雨聲變了沙鎚聲,然後一下閃電, 又一下,就好像要說明佢係特別既。 不知何時,雨聲又變回雨聲。
回想最初對雨既印象,就係細個阿媽買左一套黃色既雨衣同雨BOOT, 但係等左好耐都無落雨。過左好似三年咁耐, 終於可以穿甲上陣。雖然同樣都係返學日,但係係雨水陪伴之下就變得有趣得多。雨聲就好似無數既朋友不斷同你傾計,你只要細心傾聽,就可以聽到佢地既言語。冰涼既雨水隔住雨衣都可以感受到,令夏日既刺熱感完全消退。青蛙既叫聲取代左吵耳既蟬聲,好似氣定神閒咁唱緊歌。雨聲又掩蓋左人們煩燥既談話聲,感覺就好似去左熱帶雨林,平時既不自覺既壓力消去得無影無終。我, 愛雨。
回到現實,蛙叫聲已經聽唔到, 換黎既黎低沈既船鳴聲, 可能它在悲叫吧? 在這七百萬人的都市中,也許只有我聽到, 但我又能做什麼? 破!! 突然雷聲一響,喝止了雨, 也喝止了夢。
又,雨停了又落, 就好似女人既心情咁, 永遠都睇唔通。

mysql INSERT OR UPDATE
mysql 時,如果沒有 在primary_key 或unique有重覆時, 就會執行update 指令。
平時我都會先select count(1) 看看有沒有已存表格, 再分別insert 或 update, 今天才發現原來可以一句ko:
ON DUPLICATE KEY UPDATE
CREATE TABLE ipstat(ip int UNSIGNED NOT NULL PRIMARY KEY, hits int UNSIGNED NOT NULL, last_hit timestamp);

Kill Processes Quickly With PKILL
Kill Processes Quickly With PKILL
To kill a process I've always either used top, or the kill or killall commands along with ps|aux to discover process numbers/names. However, the pkill command removes a lot of work -- pkill firefox, for example, will search the list of processes for anything matching firefox, and then kill it (i.e. send a SIGTERM). pstree is also a pretty cool command, and will show all the processes in a family-tree arrangement, organized by who owns them."

修正UBUNTU 下 NFS 關機不會UMOUNT的問題
umountnfs.sh 會自動umount所有的nfs。所以建立umountnfs.sh的連結檔,放在 /etc/rc0.d 興 /etc/rc6.d/下就可以了。
sudo ln -s /etc/init.d/umountnfs.sh /etc/rc0.d/K15umountnfs.sh

套用YSlow!提供的建議 , 改進Apache 的效能
1) 打開需要的Apache_mod
首先要打開 authn_default , expires 兩個Apache_mod。 在Webmin下可輕易開啟。
要檢查相關的mod 是否正確開啟, 可以用PHP 的 phpinfo();
2) 修改httpd.conf
能改善的分別有三個, 分別為:
- 取消eTag
- 增加 Expires 的Header
- 啟用Gzip
在httpd.conf下, 加上
FileETag None
ExpiresActive On
ExpiresByType text/css "access plus 60 month"
ExpiresByType text/javascript "access plus 60 month"
ExpiresByType application/x-javascript "access plus 60 month"
ExpiresByType image/gif "access plus 60 month"
ExpiresByType image/jpg "access plus 60 month"
ExpiresByType image/png "access plus 60 month"

mootools 解決 a 不可以有 target 的問題
XHTML 1.0 Strict 限制了a 的tag內不可含有target的 property,
解決的方法是用javascript把全部含 rel="external"的a都用js的方法開新tab.
方法如下:

方法如下:
var ExternalLink=function(){

var e = new Event(e);
e.stop();
window.open(a.getProperty('href'));

把UBUNTU WUBI 轉移到 正式的 EXT3 partition
假設你只有一個ntfs ( window)的 文件系統( partition), 本文將會介紹如何使用 LVPM (Loopmounted Virtual Partition Manager ) 轉移到 正式的 EXT3 文件系統。
第一步 : 分割一個新的文件系統
我將會使用 UBUNTU 的Live CD來分割 一個新的文件系統。當然你也可以用其他工具分割。
第二步 : 安裝與使用LVPM

第一步 : 分割一個新的文件系統
我將會使用 UBUNTU 的Live CD來分割 一個新的文件系統。當然你也可以用其他工具分割。
- 使用Live CD開機
- 按系統, Partition Editor
- 選目前的文件系統, 按 "Resize"
- 按 "Apply"
- 在"未使用空間"內, 創造兩個新的文件系統。 其一為 SWAP, 大小約2000MB; 其二為 EXT3, 使用全部剩餘空間
- 按 "Apply"
第二步 : 安裝與使用LVPM
- 進入Wubi 的 UBUNTU
- 到這下載最新的LVPM, 並進行安裝
- 在LVPM的對話框內, 選"TRANSFER" , "sda3"(按你的硬碟位置而定, 可到"硬碟分割處理器"查看 )
- 重新開機
- 在GRUB內, 選新的UBUNTU。 如果顯示"Error 17: Cannot mount selected partition." 則繼續下一步; 沒有的話, 你已經成功了 ^^
- 按"e"修改指令。把 "root ()" 改為 "root (hd0,2) " hd0指第一隻硬碟, 2指第3個文件系統, 請按自已的環境更改。
- 進入新的ext3 ubuntu 後, 請到"
/boot/grub/menu.lst" 把 新的"root ()" 改為 "root (hd0,2) " - 完成了^^

PHP 繁簡字碼直接轉換
最近幾日都係度整緊字碼既事 ,UTF-8, BIG5, GB2312, GBK。 要做既係兩樣野:
總結如下:
iconv斷字
icon 遇到無法轉換的字時, 預設是會斷句。
可以在第2個参數加入//IGNORE
iconv("BIG5","UTF-8//IGNORE",$query);
或//TRANSLIT
iconv("BIG5","UTF-8//TRANSLIT",$query);
也可以兩個参數一起來
iconv("BIG5","UTF-8//IGNORE//TRANSLIT",$query);
用mb_convert_encoding 的話, 但會把有問題的字換成 "?"
gb->utf8
iconv("GBK","UTF-8//ignore",$word);
iconv("GB2312","UTF-8//ignore",$word);
用GBK比GB2312好, 據說係因為GBK既字庫比較大
mb_convert_encoding
mb_convert_encoding($word,"UTF-8","BIG-5");
有以下地方要注意:
charset detecting
-繁簡字碼可能會誤測, 所以次序很重要
繁簡換轉
上GOOGLE搜尋一下,
如果想簡轉繁的話, 方法是 UTF-8 -> GB2312 -> BIG5 -> UTF-8, 的確是可行的, 也不用任何外部的文件。但因為BIG5和 GB2312的字庫不夠UTF-8的大, 所以總有些字會變成 "?"。
解決方法是找個 簡體的UTF-8 -> 繁體UTF-8 的MAP , 再跟據MAP直接轉換。問GOOGLE後發現好像沒有人試過這樣做, 所以就寫了個類轉換。

可以在第2個参數加入//IGNORE
iconv("BIG5","UTF-8//IGNORE",$query);
或//TRANSLIT
iconv("BIG5","UTF-8//TRANSLIT",$query);
//TRANSLIT will raise an exception on characters it can't transliterate, however; this can be solved by using '//IGNORE//TRANSLIT' together (in that order).
iconv("BIG5","UTF-8//IGNORE//TRANSLIT",$query);
用mb_convert_encoding 的話, 但會把有問題的字換成 "?"
gb->utf8
iconv("GBK","UTF-8//ignore",$word);
iconv("GB2312","UTF-8//ignore",$word);
用GBK比GB2312好, 據說係因為GBK既字庫比較大
mb_convert_encoding
mb_convert_encoding($word,"UTF-8","BIG-5");
有以下地方要注意:
- 参數次序跟ICONV剛好倒轉
- "BIG5" 要換成 "BIG-5"
- "EUC-CN"要換成"GB2312"
- "CP936" 要換成 "GBK"
charset detecting
$encoding_list="UTF-8,BIG-5,EUC-CN";mb_detect_encoding($word, $encoding_list);
$encoding_list為 charset 的次序

09年計劃
- 幫樂a level
- 改裝個 mini laptop
- 整html2rss既interface
- 整online mp3 player with lyric support
第2樣要做既就係買返部mini laptop。 性能對我黎講無乜所謂, 上到網就得, 最重要既反而係續航力。一開始睇中aspire one, 性能ok, 但係續航力得3小時, 坐兩程車就用哂d電啦, 唔夠耐。 再搵左陣見到 eeepc 901,6cell電可以開成6個鍾機, 性能都唔差, 而且白色都ok型仔, 真係岩哂我心水。
我既plan係買完部laptop之後, 就cut左個keyboard同加個touch screen
。如果成功既話, 咁以後d online notes就可以用手指換頁,將d notes當書咁睇!跟住就係個html2rss啦。 個程式本來係諗住 for d 無rss既 網頁既, 不過整下整下好似變左偷全文既工咁, ha, 我就係咁奸架啦。其實html2rss個底(腦?)已經整好左, 係差個display未整, 不過都已經有個idea, 希望可以用得上之前學左既gimp黎整d圖啦 。
最後就係個online mp3 player。我既idea其實就係網頁既千千靜聽。家下好似唔多見有網提供歌詞識換句既網wor, 同埋我點都覺得有個server side係度,想換client果陣都易d , 第時部laptop整好左之後就唔洗煩要點將d歌同步啦
。ha, 4個target入面 , 無一樣野係關學業事架wor
what can i say~ 睇黎我真係一d想囉hon既決心都無wor~-------------------------------------------
11/12
提醒一下, 動態歌詞可以在百度下載
