			<![CDATA[ I am using vista home edition with 2G ram. From time to time after I work with my laptop for a period of time, I can not open any of programs, even my computer. Damn, is it really my computer?  QQ throws me a out of memory message window, Sometime a new window is opened with the frame only, no button, no menu... weird. Actually, the time period is not fixed. I thought it was relevant to how many application I was running.  I have to perform a manual reboot to release "memory", although the system indicated system memory only consumed about 70%. I spent a long time to find solution and installed all latest system patches,but not help at all.  ]]>

			<![CDATA[ Everyday a surprise, there are no exceptions today.

According to james' s email, system crahsed last night.  I checked tomcat log and found Exception as follows：

in thread “com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#0” java.lang.OutOfMemoryError: PermGen space

I have to say, I hate "out of memory". It is really hard to report the situation to Jonny, he think 8G memory is far enough for our application.

			<![CDATA[ 可能我是比较幸运能看到vista中能看到outofmemory的观众。2G的内存，居然经常使用不到60 - 70% 就无法打开新ie新窗口，时不时还冒个搞Java中最怕遇到的outofmemory，甚至连点我的电脑都没反应，郁闷，还是我的电脑吗?

从很多同志处征求到的答案有：vista没用过，你内存不够吧，vista很垃圾建议用xp，重新装, 砸了。

找到两个该注册表的帖子，一个改后无效，一个无法找到主键。找到一个微软的补丁帖，费劲的通过正版验证搞下补丁，当~~不适应你的系统版本。

可能是我每次窗口开得实在多的缘故。问题出现时候，我只有关掉多余窗口，我关，关关，关机~~

			<![CDATA[ 简单回顾一下acegi secrutiy在Sitebuilder的应用

acegi的正确发音为a see gee，取自某位希腊天神的名字。想想一直都叫他a c  e g i ，幸亏他名儿不叫a....z不然要累死我 ：）

我们在LPP项目中使用到了JAAS系统，相对acegi来说，它比较容易搭建和配置。但需要把resource的访问许可定义在web.xml的security contrain单元中。然后利用loginmodule返回用户的principles进行权限匹配。

而spring家族的acegi 安全系统 利用拦截器提供对url或方法级更加细粒度的权限判断，用户可以结合自己的权限系统灵活配置资源，角色，permission之间的关系。  ]]>

			<![CDATA[ 今天收到了网上预定的新本，Fujitsu Siemens Pi2515 Core2Duo 2GB 250GB。

我犯了经典的低级错误，居然把内存的2g看成了cpu频率的2pu，就这样一不小心跟2.0双核，传说中的4m cache。说拜拜了。英国地小，送个东西倒是方便，一般一两天就收到了。等我意识到低级错误的时候，东西已经送过来了。免得麻烦也就不退货了，将就着用，还可以省个几十棒子... ]]>
