If you missed Stack Overflow DevDays, there is some audio from it available on Stack Overflow Podcast #71.  I wish there was a longer version of this.  It’s only about 1/2 hour of outtakes from the conference, but it is still interesting to hear.  These snippets are followed by a long discussion with some of the speakers.  The conversation rambles and the audio quality is poor so feel free to stop listening after the conference outtakes.
