I have added this post really to let people comment about the open learning page of the Wiki. Open learning is a pet idea of mine. The idea is that high quality materials that can be used to help people learn are made available. I hope that in time people will be able to find some materials that can be used rather than have text books purchased. I also hope that people will add anything that they find interesting or useful, the page can be edited by anyone.
It is a good place to find technical information on technologies, why not learn to program with a free text book?
