A great virtualization program that runs on both Linux and Windows, but the best part is that it is open source and free. If you have ever been interesting in trying another Operating System then now is the time to give it a try in this cool app called Virtualbox.

You specify how much ram it uses, what kind of OS it is, you can even have sound in it if you wanted to. Installs each different OS into it’s neat little virtual hard drive container.
Sure there are others out there but this one is free just as the vmware player is but its interface seems alot easier to setup, use, and it runs quite well.
