Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book

But what a book. The one I found and ordered is BSD Unix® Toolbox: 1000+ Commands for FreeBSD®, OpenBSD, and NetBSD® :}
