		<description><![CDATA[程序中经常使用uniqid生成唯一id，但发现加了这个函数的代码都会慢一点，仔细测试了一下，发现uniqid的more_entropy设置为true之后，性能大大提高。在不同机器上测试过。 一台普通PC机上相差30倍， 而在cpu很差的虚拟机上相差了4000倍！！！

测试代码：

		<description><![CDATA[treapdb是国内个人开发者的一个开源项目，支持memcache，thrift协议。但如果使用memcache协议，就无法支持range,prefix等特性了（如果丧失这些特性，还不如直接用memcache了吧）。

thrift是apache的一个项目，支持10余种语言。也要感谢facebook的大规模使用，让更多的人知道了这个东东。

作者提供了java/python的例子，这里仅提供php的操作方法。

关于thrift的编译/php扩展的编译，就不再啰嗦了，无非都是configure/make/phpize等命令，可以参考：

		<description><![CDATA[由于lighttpd1.4.21之前的版本不支持Expect: 100-continue，所以有可能访问出现“HTTP/1.1 417 Expectation Failed”等错误提示，搜集整理了很多解决方法，如下：

1. 升级到 lighttpd 1.5.x，那应该没有这个问题了

2. （推荐）升级到 lighttpd 1.4.21 或以上版本（即最新的realease版本），在配置文件中加上一句
