what are your favorite screencast/webcast directories for all things software engineering?
I know of
- http://peepcode.com/ (not free)
- http://videolectures.net/site/list/top/
- http://www.showmedo.com/
- http://www.bestechvideos.com/
SO has a few questions on webcasts, but they are for specific topics - Django, Rails, etc.
Among other things I am interested in somewhat advanced Linux/Unix material, so I look for LUG sites - sometimes they post videos from their monthly meetings, but I have not found any centralized directory of those videos. is there one?
thanks!
