One year ago, I quit my job, started a bike tech company, and now I ride my bike ... a lot. Still looking for that bike shop to sponsor us (hey, and upgrade my shifters while they're at it!). gocomics.com/calvinandhobbes… via @GoComics

Very full of Swiss fondue. Yum.
Opened Last Drop coffeehouse at 7 AM ... had to wait for espresso machine to warm up first! Gots works to be dun.

I rode the Shinkansen today. Poor Acela feels like a stood-up prom date, crying at home.
Biking into 30 mph headwind not fun

Wondering how to integrate a control/planning approach between a cubical complex and a CW-complex, both over the N-torus.
