1.大家在实际工作中，会写各式各样的赋值语句。
比如最常用的obj.style.display = "none";
如果这样的赋值语句一多，obj.style一排下来都要看晕了
下面我的base.js中的extend函数可以允许用json格式赋值属性甚至是函数句柄
/**
* 扩展函数
* @param target 需要扩展的对象
* @param params 要往target里放的属性和方法
*/
function extend(target, params) {
if (!target) {
target = {};
}
for (var prop in params) {
target[prop] = params[prop];
}
return target;
}
2. 由于ie不完全遵守w3c标准，他的事件模型和别的浏览器不一样。调用的方法也不一样。
如果遇到要为控件动态增加事件。用onclick = function() {}一类的在dom动态创建的时候不一定有效，而且无法绑定多个句柄。下面介绍一个通用的支持全浏览器的绑定事件函数。
在大部分情况下，useCapture用的是false，所以这里干脆写死。
/**
* 动态创建事件句柄
* @param control 需要扩展的对象
* @param eventName 事件名
* @param fn 函数句柄
*/ ......

《Oracle大型数据库系统在AIX/UNIX上的实战详解》集中讨论的继续。做了一周关于Oracle在32位windows上实施的培训，恰好期间有几位Oracle用户邮件询问关于Windows系统调整问题。正好吧，把准备的一些内容共享出来。如果Oracle使用大于1.7的内存，需要一些特写的设置。参见下面来自metalink的论点： Large page support is a feature of Oracle Database 10g Release 1 (10.1) or later. It provides a performance boost for memory-intensive database instances running on Windows Server 2003. By taking advantage of newly introduced operating system support, Oracle Database 10g Release 1 (10.1) or later can now make more efficient use of processor memory addressing resources. Specifically, when large page support is enabled, the CPUs in the system will be able to access the Oracle Database buffers in RAM more quickly. Instead of addressing the buffers in 4KB increments, the CPUs are told to use 2 MB page sizes in Physical Address Extension (PAE) mode and 4MB page sizes in non-PAE mode when addressing ......
