For those of you who managed to get your hands on a PS3 and not get shot in the process, you're probably itching to use that big ass machine to do some fancy media playback—like Sony's been hyping. The good news is that you can use your PS3 as a media hub, but the bad news is that you'll have to install Linux.
Here's a guide to installing Yellow Dog Linux, the Linux that was designed for the PlayStation 3.

After you're done, you can use your PS3 as a DVR, a media machine, or even a webserver.
