Take Stanford courses for free

"Stanford University is offering the online world more of its undergraduate level CS courses. These free courses consist of You Tube videos with computer-marked quizzes and programming assignments. The ball had been started rolling by Sebastian Thrun and Peter Norvig's free online version of their Stanford AI class, for which they hoped to reach an audience in the order of a hundred thousand, a target which they seem to have achieved. As well as the previously announced Machine learning course you can now sign up to any of: Computer Science 101, Software as a Service, Human-Computer Interaction, Natural Language Processing, Game Theory, Probabilistic Graphical Models, Cryptography and Design and Analysis of Algorithms. Almost a complete computer science course and they are adding more. Introductory videos and details are available from each courses website."
