RPMForge: Could not retrieve mirrorlist http://apt.sw.be/redhat/el5/en/mirrors-rpmforge error was [Errno 12] Timeout: urlopen error timed out

Earlier today I was having trouble on one of my development servers reaching the RPMForge repository which I use on CentOS Linux servers. I believe the issue to be some form of odd network issues either at the development servers location, on the repos end, or somewhere in between. Regardless of the issue at hand there is a work around that can be used which is described in more detail below.

What Is QualXServ Service Agreement, Can QualXServ Service Agreement Be Uninstalled?

I believe the QualXServ Service Agreement which comes installed on Dell netbooks, laptops, and desktops is really just a PDF file. The PDF file is the service agreement for in-home or on-site repair which typically comes with the purchase of a new Dell computer. When you remove the application from your installed Programs the PDF is removed from your system. I recommend simply copying the QualXServ.pdf file from its default location to another location before removing the application from your computer just in case you happen to need it. Follow the directions below to save the file to a familiar location and then remove the application from your PC.

Below I describe how to find out the dependencies of a specific gem by querying the remote server but also how to download a specific gem version to see what gems are dependents.

How To Delete A Profile On Xbox 360

Over the past couple of years I have had many friends use my Xbox 360 and in doing so they added their profiles to the device. Every time I want to login I have to sort through multiple profiles to locate the one I want to login with so I finally decided to clean up all of the profiles except for the primary one I use. You would expect the Xbox 360 interface to have a delete option directly from where the profiles are listed however it probably is not included there to cut down on accidentally deleting the incorrect profile. Below are instructions on how to delete profiles from your Xbox 360.
