Info Linux and Microcontroller

New comic book Hacket and Bankwell book geared at introducing GNU/Linux — specifically Ubuntu GNU/Linux — to new users. At about 30 pages long, the first issue is an easy read, and doesn’t get too bogged down by technical details, political ruminations, or an over-abundance of geekiness. A couple panels are dense with historical information, but it doesn’t detract from the pace of the simple story too much.
