What did you all do?
It turned out that we all had experience mobbing. We picked an old advent of Code task, opened up repl.it and rotated driving on the same keyboard. 5 min intervals kept the pace high. One of us works at repl.it, so it was funny that I already had it running before we started. He showed us some config tricks. The laughter and camaraderie was the highlight of my pycon so far.
