I never got to meet JPB, but I was lucky enough to attend his keynote at PyCon 2014 in Montreal. It's a great talk, should you have a spare 45 minutes.

He is (indirectly) responsible for the existence of a hackerspace in Fresno, CA. Last year a few of us got together to talk about starting a chapter of the Electronic Frontier Alliance. That conversation morphed into, "fuck it, let's just start a hackerspace."

So thanks JPB. Rest well.
