Ask HN: Where do you find good tech talks?

I've noticed that there are a lot of great talks recorded on Blip.TV, but I can't seem to find anything decent through their search :-/ I used to watch almost every Google Tech Talk, but they seem to have stopped posting them as often, and the subjects are also less intriguing. Where do you find good tech talks? Here is a list of the resources I follow at the moment: Google Tech Talks - http://research.google.com/video.html ConFreaks - http://confreaks.net/events Pivotal Tech Talks - http://pivotallabs.com/talks StartupSchool at JustinTV - http://en.justin.tv/startupschool/videos InfoQ presentations - http://infoq.com Stanford Entrepreneurship Corner - http://ecorner.stanford.edu/podcasts.html Business of Software - http://www.businessofsoftware.org/prevyear.aspx - Click "Show more" Learnivore screencasts - http://http://www.learnivore.com VideoLectures - http://videolectures.net/ - Machine Learning, Statistics, NLP, ..
