We've written about free e-learning resources and tools, such as
Moodle, several times here on OStatic, as well as
collections of open source tutorials. Many universities are picking up on the fact that it is easy to use free, open source tools such as Moodle to provide classes online that anyone can take. U.C. Berkeley provides
free online classes based on Moodle, and M.I.T. has a collection of over 1,900 free courses on its
MITOpenCourseware site, many on tech topics. MITWorld also has
a searchable database of free, educational videos. Here are some notable examples of classes and seminars that may be of interest to you.
