Vista Performance

The new animations in Windows Vista look great for the first month or so but then they can become an annoyance since they feel like they increase the amount of time it takes to minimize and maximize a window. If you can live without the minimize and maximize animations that you can bring back the super fast feeling of your windows instantly disappearing and appearing by disabling the min/max animations.

Follow the steps below to make your windows faster:

1. Click on the Start Menu and key in SystemPropertiesPerformance and hit Enter.
2. On the Visual Effects tab uncheck Animate windows when minimizing and maximizing.
3. Click OK.

FATAL: Module off not found. - Solution

You may see the following error in Fedora 8 while starting / restarting the network (service network restart):

FATAL: Module off not found.

Let's see how we can fix this.

This happens because you have entered a line in /etc/modprobe.conf to disable ipv6:

alias ipv6 off

In Fedora 8 you should change it to:

options ipv6 off

Now restart network:

service network restart

You will not see the error.

wget: a usful linux tool to check webservers' response

wget -S --spider http://www.google.com/

Using this tool was the reason to detect the week long problem in kobool server which caused 50% of the user to fail to open kobool.com.
The failure was that Internet explorer was hanging during load time.
I found that the header contained Content-Type: text/html; charset=UTF-8 which was not found in the old server. By commenting DefaultCharset utf-8 in httpd.conf, the problem was solved.
