The knowledge share discussion is to be held on this Friday, my subject is about the IPC (Inter-Process Communication) on the Unix environment. In the ecbattle project we programed using Internet Socket to communicate between PHP script and the taskserver compiled by c++, exactly, it's easier, but that's not efficient enough i think Tremble

悠闲聊天

Doesn't matter whom you are with
Doesn't matter where you are going
Don't you know I'm still waiting here for you and pray for you
In the sunny days, sun will light your day
In the windy days, wind will lead your way
I have to say you're my treasure moments never gonna walk away
In the rainy days, rains will share my tears
In the stormy days, storms will steal my pain
Just go your way and leave things all behind spread your wings and fly away
I'm pretending you're mine I'm wishing you'll be fine

网页游戏是互联网下一个蓝海

奥运年很热闹，互联网行业也如奥运般踩踏着远航的甲板，“互联网的下一个蓝海是什么？” 每一个跃跃欲试的创业者们都在问。过去的一年里，网游依然是行业关注和互联网利润的焦点，但是随着人们的需求改变，大量的人群已经开始喜欢轻量级的网游- -网页游戏（webgame）。

昨天做的 XML 封装类

由 hdwong 于周一, 2008-05-19 12:22 提交。

PHP 自带的对 Xml 的操作模块有 DOM，SimpleXML，XMLReader，因此 Zend Framework 也没有这个必要重复做一个轮子，可以理解。但是每次读取 XML 都要重新进行解析，而同一次访问中内调用多次(可能在不同的脚本内，MVC 开发模式下，我还不能很好地避免到多个模块内调用同一个模块的可能性 Embarrassed )的话，系统都会重新进行读取与解析，这样无疑浪费了系统资源。所以在我的项目里，写了一下这么一个 Xml 类，里面定义了一个静态的变量，用来保证已载入的 Xml 数据不会被重复载入，并且用了 Zend_Cache 作为缓冲机制。
