I recently had the privilege of teaching three days of workshops in Japan. I had a fantastic trip, and a great experience with the team at Osaka City University. This story, however, is about the days before. The Scenario The workshops were full of new teaching material. Due partially to hesitation about putting very in-progress work online, and mostly to doing lots of work on planes and in other wifi-less situations, my Github commits were rare in the months leading up to my visit, but I took an uncharacteristically laissez-faire attitude toward the situation.
