The NSConference 2010 setup looks great. I’ve been lucky to attend and speak at the 2009 edition, which was terrific, thanks to the vision, work and human qualities of the folks at MDN, Steve Scott and Tim Isted. The videos of the 2009 edition are all available for purchase. This includes the talk I gave on “New Cocoa programming superpowers”.
There are also a number of backstage and interview videos at Pomcast.com (search for "NSConf"), including the super geeky Hacking F-Script & Pick&Play, starring Jason Harris, and the french F-Script interview in the dark.
