There's an interesting handbook on Linux that newbies may be interested in:

I had a cursory look (the server appears to be having problems tonight), and it seemed fairly informative. I understand that it came bundled with MDK8.1. It may be of interest to newbies and more experienced users alike. Anyhoo, I hadn't heard of it before and there may be a few lurking newbies out there....
