My friend Neil posted this article earlier today. Got me thinking. Enough so to post again after a couple of months. The article is about Harvard's popular CS50 course. David J. Malan took over and redesigned the course in 2007 and it's been his ever since. This year, Malan is on sabbatical and the course is being taught by Henry H. Leitner who was one of the instructors prior to Malan's reworking of the course.
