Assembly TV has just started the Internet broadcasting from Assembly Summer 2011 Computer Festival. Expect to see lots of interesting material. Again this year they have some interesting ARTtech seminars worth to watch. And I expect the computer demo competitions to be high quality this year.
This year the Assembly TV people have made a nice web page report on their current AV setup on their blog so I might not need to make my own behind the scenes report like I did two years ago.
