On Nov. 23, Geertjan and me talked at JUG Cologne . Apx. 50 members joined the talks. Thanks for your interest!
Geertjan just described his impressions of the talks in his blog .
My talk was a slightly extended version of a talk I first hold at the parallel conference. Get the slides from my former blog .
