If you use Ubuntu, the full circle magazine is a great resource, go check it out. For example from the latest issue I’ve learned that I should install vim-nox on my servers if I want to upgrade my 1980’s experience to 1990’s :-).

I there is one (small) issue, it is the fact that the PDF is very CPU intensive (I’m not really sure about the cause), but it is very good looking and professionally done. Go look at it if you use Ubuntu. And consider donating or writing an article or two :-)
