Of the many, many interesting things happening in Copenhagen this summer (SEA, SWAT, ICALP) we'd like to add one more: a Hashing Summer School at the University of Copenhagen. Here's the web site. This was the brainchild of Mikkel Thorup, who knows a thing or two or three about hashing, and is co-organized by me and Rasmus Pagh. We've got a great set of speakers, and we expect a mix of lectures, problem-solving exercises, a poster session, and other such fun and learning. The registration deadline is May 15th; check the web site for details. If you're coming out to Copenhagen for other activities, or just want a good reason to visit the beautiful city, take a look. I hope to see you there.
