前几天在线测试nginx
啥都不说了，看截图吧:)
nginx在处理高并发的确实非常不错，前几天另外的同事专门做过相关测试，低请求下，nginx和apache其实差不多！

蚂蚁
在网上看到蚂蚁改版的消息，特地跑去看看，结果发现原先注册的帐号不能用了，改版后就全部清除了。
伤感情啊… -

一起网只是一个域名，承载了谢文的理想和理念。对于谢文来说，一起网这种web 2.0形式的个人门户，是他一直想做而没有资源做的，今天他如愿以偿了。
刚简单的测试了一下，发觉好慢…ft..域名：http://www.yiqi.com，有兴趣的朋友可以去溜达溜达，不过现在是内侧阶段，必须有邀请才可以注册。 -

利用HTTP_REFERER建立盗链黑名单
目前国内知名网站在针对防盗链方面都做的不尽人意，要么格杀无论，要么干脆不做！格杀无论的站点总的来说还是不友好！
所以针对这些，BDFS里将引入：利用HTTP_REFERER建立盗链黑名单，这样可以方便限制非法的域名（甚至url），这样既可以避免风险和成本，又可以给用户提供更友好的功能。 -

Lingerd
What is lingerd?
Lingerd is a daemon (service) designed to take over the job of properly closing network connections from an http server like Apache.Because of some technical complications in the way TCP/IP and HTTP work, each Apache process currently wastes a lot of time “lingering” on client connections, after the page has been generated and sent. Lingerd takes over this job, leaving the Apache process immediately free to handle a new connection. As a result, Lingerd makes it possible to serve the same load using considerably fewer Apache processes. This translates into a reduced load on the server.
Lingerd is particularily useful in Apache webservers that generate dynamic pages (e.g in conjunction with mod_perl, mod_php or Java/Jakarta/Tomcat).
More importantely, lingerd can only do an effective job if HTTP Keep-Alives are turned off; since keep-alives are useful for images, the recommended lingerd setup is to have an Apache/mod_whatever/lingerd server for the dynamic pages, and a plain Apache (or thttpd or boa) for the images.
可惜目前只支持apache1.3的版本，真希望能出for apache2.2.的版本 :^_^

memcached-tag
What is memcached-tag?
Memcached is a high-performance, distributed memory object caching system.
We add “Tag Function” for memcached. Propose is remove several keys with the same tag in one operation. This function will help the API programmers (such as php) do the delete operation easily, and reduce the network load. We use hash and splay tree, make the “tag_add” and “tag_delete” commands very quickly, and save memory as much as possible.
There is a brief introduction about what we thought and how we considerate. You can see it here
The patch and full source code can be downloaded on the right, you can also see the change log here. And we will update it in the future.
You can also visit here by http://memcached-tag.googlecode.com and left your message here.If you find BUGS, please tell us, thanks very much!
New memcached command* tag_add
