There was a lot of interesting stuff shown at Valve's Steam Dev Days last month. Unfortunately for many, only the retellings of the events via the developers and gaming press were available for the masses. Fortunately for people who want to listen to the presentations themselves, Valve has just posted the videos of the event, as well as the slides of some talks.

The videos are edited well, showcasing presenters and their slides when needed. So if you are interested in the more technical parts of game development and marketing with some free time on your hands, there is a lot of interesting stuff to listen to.
