Let's skip the user group this month. Doesn't seem like anybody has any presentations.. Let's try to get something going next month.
Trifork (big consultancy company using Riak) is hosting a "nosql roadshow" here in Berlin. http://nosqlroadshow.com/nosql-berlin-2013/
They asked me to promote their conference to you guys and to make it a sweet deal they offer us a promo-code. With the magical code ERLANG40 you can get 40% off.
