After so many years of organizing #geecon, we've honestly lost track of all the details.
Luckily, Peter Kofler didn't. Since 2009 he's been documenting the journey. A virtual #geecon museum, memories, swag, and a bit of nostalgia:
geecon-museum.code-cop.org
Thanks, Peter, and everyone who's been with us since the beginning.
