On-line courses: Join the Million

Coursera, the company that provides support and Web hosting for massive open online courses at top universities, announced Thursday that more than 1 million students have registered for its courses. The company now serves as a MOOC platform for 16 universities and lists 116 courses, most of which have not started yet.

I took a course from Coursera in Cryptography and it was quite good. I am taking two now; one in quantum computing and one in finance. The courses do take time to watch the videos, do the homework, and simply keep up. Still, they're free, interesting, and if you have the time, worth the effort.
