BlackHat 2011/DefCon 19

I spent last week in Las Vegas, for BlackHat USA 2011 and DefCon 19 -- my annual security conference pilgrimage. Overall impression: the quality of the actual presentations was below-average this year, but it was still an educational experience, a good professional networking event, and probably the most fun I've had at DefCon so far.

Rather than recount everything here, I'll link to my full trip report on my security blog:
