John works for VMware in the Open Source Program Office on upstream open source projects. In a previous life he's worked on the MinnowBoard open source hardware project, led the system administration team on kernel.org, and built desktop clusters before they were cool. For fun he's built multiple star ship bridges, a replica of K-9 from a popular British TV show, done in flight computer vision processing from UAVs, designed and built a pile of his own hardware.
He's cooked delicious meals for friends, and is a connoisseur of campy 'bad' movies. He's a Perl programmer who's been maliciously accused of being a Python developer as well.
