I have been participating in the "History of the world since 1300" at Coursera and find the content absolutely fascinating.

What are the other online courses that you can recommend to a fellow hacker?

I've done an AI course at Udacity - https://www.udacity.com/course/cs271 - I found it pretty good if you are interested in learning the very basics of AI

I also enjoyed their 3D Graphics programming course cs291.
