The hot summer days of vacation are over and the slightly cooler summer days of the beginning of the academic year are here. Thirsty after all this heat? Missing your CS and AI friends, or do you want to meet your new colleagues? Curious what happened to everybody over summer? Come to the welcome back social, where you will find all your friends and some free beers to deal with all these issues in one go. As per usual, the first 170 beer/sodas/shots are on us.
