An excellent piece on self-education from the NYTimes:
A free online course at Stanford University on artificial intelligence, to be taught this fall by two leading experts from Silicon Valley, has attracted more than 58,000 students around the globe -- a class nearly four times the size of Stanford's entire student body.
What's more, the class is completely free, including evaluation through online tools. You won't get Stanford credit, but you will get a "statement of accomplishment" for attending.
