Windows

I'm going to upgrade zabbix agentd from 1.1.4 to 1.4.4 on all my Windows servers.

I use Remote Desktop to connect some dell servers, and the default background image is slooooow. So after a few  minutes research, here's the solution to remove it.

Telnet is not installed by default. Here's the step to install on Windows Vista
1. Open control panel
2. Open Programs and Features
3. On the left panel, select "Turn Windows Features on or off"
4. In the tree, select "Telnet Client", and click OK

Telnet is the basic tool for a network administrator.

When I try to connect to a server by Remote desktop, it report "The terminal server has exceeded the maximum number of allowed connections".
Here's the step to disconnect the un-used session and make yourself able to connect it.
1. start tsadmin.exe from a windows 2003 server that you have access
2. right click on "all listed servers", then select "connect to computer", and type in the IP address for that server
3. Then you would able to disconnect other session and you can login

Just installed Visual Web Developer 2005 Express Edition on Vista, and it won't stop at the breakpoint.

Solution:
1. Start VS Web as administrator
2. right click project, select "Property Pages", in Start Options, make sure Debuggers->ASP.NET is checked
3. open web.config, make sure you have the following lines:
    <compilation debug="true"/>
4. Open IE, in Tools->Internet Options, select Advanced tab, make sure the "Disable script debugging (IE/Other)" is unchecked

1. Recording conversion: I use dBpoweramp Music Converter to convert my recording before, and found it is no longer free recently(it's no longer free for sometime). After tried a few other software, I found foobar2000 is one of the best converting software to let you easily convert between WAV/MP3/MP4/OGG etc. Visit here to download the latest version.
