Tim Berglund is attending the JavaZone conference in Oslo, Norway, for the third consecutive year and plans to host a social gathering known as a drinkup at Cafe Con Bar, a venue near the Oslo Spektrum. The event is scheduled for Sunday, September 16th, at 8:00 PM and will provide an opportunity for attendees to enjoy drinks together while discussing topics such as Git, GitHub, and the vibrant technology scene in Norway. The gathering promises to be an enjoyable occasion, and Tim humorously notes that mathematicians are working on proving that a good time is guaranteed.
