I'm enrolled in this class now--pretty funny to see it on the front page of HN.

For anyone who's interested, the lectures generally consist of very high-level views of various elements of programming; anything from version-control to a C++.

IMO the best parts of the lectures are Kernighan's anecdotes: he constantly drops in stories from his time at Bell Labs, and even includes some correspondences and comments from the very programmers who created the technologies on which he lectures.
