Fosswire offers a Cheat Sheet to Ubuntu Users

I discovered a great blog for open source software that offers tips and tutorials along with great articles. The posts cover all the linux distros and aren't Ubuntu specific, but I found such a useful pdf Ubuntu Reference Cheat Sheet that I had to post it here. If you're interested in even more Ubuntu posts on Fosswire, there's a search window right at the top of their page where you can search for whatever specific topic that might be of interest.
