On last years SoCraTes Conference I had the pleasure to meet Sandro Mancuso from the London Software Craftsmanship Community (LSCC). Following his Twitter account I stumbled upon a meetup concept called "Code & Coffee" which the LSCC organizes very regularly. At a "Code & Coffee" developers would meet up early in the morning before work to discuss and hack at some coffee place.
I liked the idea very much and started such an event in Bonn. Our first test-event was a success, so that we now open up the concept to anyone who wants to join.
There is a Google+ Community Code & Coffee Bonn where you can join and get regular invites to the events.
Our next event is on March 26th. For more details see the Google+ page.
Looking forward to seeing you there!
