IIS启动不了 Error 1053

当启动IIS的时间比系统已配置的时间长时,IIS将无法启动,并报1053错误.
Could not stop the Windows service name service on Local Computer.
Error 1053:The service did not respond to the start or control request in a timely fashion.

解决方法是首先确认World Wide Web Publishing服务是否已经启动,没有的话就启动它.
如果World Wide Web Publishing也无法启动,并报1717错误的话,再确认Event Log服务是否已经启动,
Event Log服务启运后应该就可以启动World Wide Web Publishing服务了,之后IIS也应该能够启动了.

Ubuntu 浏览器中Flash中的文字乱码的解决方法

不知道这个现象是不是仅仅出现在UBUNTU中，其它LINUX系统OS还没验证过。原因是/etc/fonts/conf.d/49-sansserif.conf文件引起的，解决方法就是删除它（保险点还是重命名为好）。

解决方法当然是安装该包了。
$ sudo apt-get install libopenssl-ruby

Rails2.2.2创建数据库时utf8_general_ci错误

最近将Rails的版本更新到了2.2.2,顺利更新完成之后准备做一个Demo,然后当执行rake db:create命令创建数据库时,却报了如下错误:

Couldn't create database for {"encoding"=>"utf8", "username"=>"root", "adapter"=
>"mysql", "host"=>"localhost", "password"=>nil, "database"=>"atod_development",
"pool"=>5}, charset: utf8, collation: utf8_general_ci (if you set the charset ma
nually, make sure you have a matching collation)

乍一看好像和什么字符集有关,弄了一下午也没解决.昨天不经意间将database.yml中的localhost换成127.0.0.1,竟然成功创建了,具体就不知道是什么原因了.只记得更新以前曾安装了windows版的Oracle11g,那时新建了一个"loopback adapter"网络连接,不知道和这有没有关系...
