OpenCourseWare is such a cool idea and has a ton of potential.

It's really unfortunate that 95% of the courses that have been put up don't have nearly enough content posted online to be of any use. Just take a look at the lecture notes and labs posted for this course. You're far better off just looking up some random python tutorial online.

You can often find videos of entire course lectures posted online by using google video. Or if you're looking for an academic conference style crash course, check out http://videolectures.net/
