MIT Open Courseware - Free Lectures
- Actually MIT's OCW is pretty popular and many people know about it, but I am sure there are other sites as well which have quality tech education type material, some of the links I use below, What other links do HNers have?Please pass along here and everybody could gain from that - 1) MIT -> http://ocw.mit.edu/OcwWeb/web/home/home/index.htm - 2) National Program on Technology Enhanced Learning ->http://www.youtube.com/user/nptelhrd - 3) Google Tech Talks -> http://www.youtube.com/user/googletechtalks 
- I've thought about aggregating all online conference talks, keynotes, workshop,etc videos into one site. Would this be useful to everyone here? 
- I like this trend, but I have some reservations about the usefulness of the material. It's not generally suited for self studies, as it's made for a full time student and while the lectures and notes are open, the course ware isn't. As far as I know there's no easy way to take an exam or get a grade. It also seems hard for other teachers to use, as it doesn't contain any instructions from that perspective. - So while I like the initiative, I currently can't see any widespread usage for it and think it needs to evolve to become "truly" open.
