Wow !! this is the coolest thing I have heard for some time. Massachusetts Insitute of Technology (MIT) is offering FREE opencourseware is varied topics from Aeronautics all the way to Women's studies.. anyway I am interested only in "Electrical Engg & Computer Science". It has numerous topics ranging from Graphics to Compilers. They have good online course material, which is of great value. I am really enjoying reading the course on "Computer Graphics".
Choose a topic and get rocking !! My weekends are going to be busy for some time.. Don't we sometimes hope that we could have got access to such amazing sites a bit earlier in our career.
Better late than Never !!
