I spent most of the video trying to figure out what book were on the shelf behind them (I did pay attention, too). I can make out the O'Reilly books on the top left, but the rest I can't match to anything I've got. There's maybe an Apress book in the horizontal stack there? Dunno why, but for some reason lists of what books various startups have (and refer to a lot) might be interesting.
