Just who is Dick Baldwin? Richard G. Baldwin is on the faculty of Austin Community College at the Northridge Campus. Nothing remarkable about that – but what is remarkable about Dick Baldwin is his apparent dogged determination to create well-written tutorials on every Computer Science problem known to man.

Baldwin has his massive collection of tutorials up for a sale but he also has a substantial amount of stuff available for free, including a lot of class material. for folks who want a copy to study offline, but all of the tutorials can be had for free on his personal site.

All pretty good stuff, written in a somewhat breezy style, and done in the way I like it, with a stress on explaining how it works by illustrating with code.
