Free CS course from Stanford

This is amazing. Stanford has made basic CS and Robotic courses online for free. Sometime ago I was just browsing on the fee structure @ Stanford and saw that it was like $5500 for 4 credits. Giving it away for free is a great move :). I am sure many people around the world will get benefited from this. Oh also, I recently read about many Prof's coming together against the book publishers who charge a lot for school text books. So that kicked off a project called connexions where Prof's and other industry experienced people share their knowledge and notes and references on subjects. Glanced through it and it looks good.
