Hac4 is now over, everyone has arrived home safely and all the equipment has been returned. 27 people attended, though not everyone could come every day. 10 attendees travelled from several European countries and from the US. People hacked on lots of projects, including Yi, Cabal, ByteString, a new web application interface, QuickCheck, CGI, first-order logic reasoning, Allegro bindings, Haddock, the community server, HAppS-HSP, replacing libgmp in GHC, Squiggle, restricted monads, and more.
We also decided to set up a Haskell Hackathon Steering Committee which will help find hosts for future hackathons and aid the local organizers.
Thanks to sponsorship from Credit Suisse and Galois, we could provide food for everyone during the whole hackathon. This made it possible to keep the group together and keep hacking (some stayed well into the night). The Department of Computer Science and Engineering at Chalmers University of Technology and University of Gothenburg provided space and networking.
A big thank you to everybody who made this happen by sponsoring, attending and helping out with the organization!
