Great webcasts from Berkeley

[ktu]

Berkeley  university is making publicly available webcasts from many of 
their courses.

I found this course, CS 61C Machine Structures, to be incredibly good, 
and thought I'd share the link:
http://webcast.berkeley.edu/course_details.php?seriesid=1906978500

If you are interested in C-programming, operating systems, assembly/ 
CPU, memory management etc,
and are not already a guru, this is gold.

(Maybe most people on this list are level 10 gurus, I don't know)
