Summary of changes from 3.0.0 to 3.0.1
-
Objects with grace and keep set were mistakenly seen as candidates for the shortlived storage, but would not be cleaned up quickly, something that manifested as if there was a memory leak. This is now fixed.
-
When multiple clients were waiting for an object, all clients would be woken up when an object became available, leading to stuck threads. This has now been fixed
-
A bug in how XML entities were handled with ESI has been fixed
-
The documentation has seen numerous updates
-
varnishncsa is now more stable and has support for showing arbitrary request and response fields、
期待varnishncsa有更好的表现

近一段时间，弄varnish，周五晚间已上
原来一直用SQUID2.6，有个问题一直没有解决，同样的配置，同样的版本，有的站点是GZIP，有的就不压缩，多次检查问题仍无果，后来，索性用varnish测试，一次成功，13台squid均换成了11台varnish，大概进行了1个多月，才基本搞定，期间日志问题更是头疼，varnish3出现解决了大问题，可以定义日志格式，后来又经过了其他一系列磨难，终于上周五，varnish修成正果，这个星期就是检查看看有哪些小地方需要修改，比如日志格式过大的问题，原来SQUID不记录图片日志，nolog就可以，varnish还没查询，继续努力中… 等有结果了，应该写个PDF大家共勉之。
nginx 1.0.5 放出，修正如下
Changes with nginx 1.0.5 19 Jul 2011

Thanks to Maxim Dounin.

再也不买DELL笔记本了
本人有个DELL 1425笔记本，2年前买的，现在还差10几天过保，出现花屏问题，经DELL官方维修站鉴定为显卡虚接，因此独立显卡是焊在板子上的，需更换主板，但此时发现我主板上其他地方有人为焊接痕迹，可我本人这2年从来没报修过，也没有拿到外面修过电脑，等于此电脑根本就是个返修货，从出厂的时候板子就被焊过了，这种事情打官司也是赢不了的，因为主板在机器里，你收货的时候不可能打开机器外壳检查板子，只能自认倒霉，找朋友焊显卡接口。
在此，我对看到此文章的朋友建议不要购买DELL笔记本产品，原因如下：
1、DELL笔记本外壳螺丝处无任何防护胶条，很难判断是否打开和维修过。
2、不要购买延保服务，因为像我这种问题即使购买了延保服务也只能自掏腰包。
3、从我自身遭遇来看，如果DELL把返修品当成正品发给你，除非你收货时让送货员打开机器后盖检查，否则你也不知道是否是返修品。
基于以上几点，再也不碰DELL产品（单位的服务器除外）
