Some context: this was a DeCal class which is run by students.

From the DeCal website: "DeCal is a student-run democratic education program at the UC Berkeley - here, students create and facilitate their own classes on a variety of (often unorthodox) subjects."

Came here to say this.

The DeCal program is really awesome. I took one titled "Advanced Unix Systems Administration" my first semester that was possibly more valuable than some of the faculty-led courses I was taking at the same time.

I second this -- the Unix System Administration series (http://www.ocf.berkeley.edu/decal/2008-spring/advanced/) and the DeCal classes in general were some of the most rewarding classes I took at Cal.
