jQuery 1.4 研究與報導 之個人見解（二）
New .toArray() method
.get()用來轉換陣列,將被移除.
jQuery1.4 請使用.toArray() 不用帶入參數可以自動解析.
jQuery() returns empty set
在舊版jQuery1.3 jQuery() 會回傳整個結構函數.
jQuery1.4 將改善此現象 回傳一個空函數.
PS:保留jQuery().ready() 和 jQuery(function(){}).
jQuery(“TAG”)
快數透過TAG目標定義選取.
CSS
The performance of the .css() method has seen a 2x performance improvement.
.css()速度大幅增長2倍,請看官方圖表.
The performance of the .addClass(), .removeClass(), and .hasClass() methods has seen a 3x performance improvement.
.addClass().removeClass().hasClass()速度大幅增長3倍,請看官方圖表.

jQuery 1.4 研究與報導 之個人見解（一）
本文皆為個人見解如有錯誤,煩請賜教.
jQuery 1.4 於2010/01/14 釋出.
官方同時間開啟一個活動專欄頁面報導 14 Days of jQuery.
In celebration of jQuery’s 4th birthday, the jQuery team is pleased to release the latest major release of the jQuery JavaScript library! A lot of coding, testing, and documenting has gone into this release, and we’re really quite proud of it.
I want to personally thank Brandon Aaron, Ben Alman, Louis-Rémi Babe, Ariel Flesler, Paul Irish, Robert Katić, Yehuda Katz, Dave Methvin, Justin Meyer, Karl Swedberg, and Aaron Quint who put a lot of work into fixing bugs and getting the release out the door.
文中開頭就敘述了.1.4的釋出跟jQuery的生日是同一天（蠻有意義的）.並且更新了官網說明文件.
Downloading
這次官方使用Google Closure Compiler 來做壓縮.
- jQuery Minified (23kb Gzipped)
- jQuery Regular (154kb)
還有再google提供的cdn

QEMU on FreeBSD 8.0 再你的的server上,建立自己的虛擬電腦 lab 以供測試開發.
一直以來你是否有跟我有相同的困擾? 手頭上只有一台機器,效能尚可系統負載不高.
但工作需要執行多種環境測試實驗,無法隨身攜帶各種系統. 等等困境….
一般的虛擬機器軟體又需要圖型介面,才可設定使用.(這無疑對系統又是一種負擔,與當機危險)
現在終於有實際解決方案～所需費用 0.

PyMSN Python 開發的MSN 模組 (一)基本介紹
安裝可以參考 閃光的 BLOG https://blog.hinablue.me/794
基本使用介紹:

- Log可自行調配 是否輸出存檔
- 在使用任何 套件模組 像這種依照物件下去設計的 千萬不要改原始碼(等改版 你就知道痛了)
- 這邊 一開始如果用 預設的範例test.py你會遇到 傳訊息沒回應或出現event_handler 等等error.(稍後會講解)
