We am glad to announce ZuriHac 2015, a annual three-day Haskell hackathon in Zurich. This year it's sponsored by Google. When: May 29th - May 31st Where: Google office, Zurich, Switzerland ZuriHac is an international Haskell hackathon: a grassroots, collaborative coding festival with a simple focus, to build and improve Haskell libraries, tools, and infrastructure. This is a great opportunity to meet your fellow Haskellers in real life, find new contributors for your project, improve existing libraries and tools, or even start new ones! I am happy to announce that Edward Kmett will give a talk. We are still in progress of nailing down the details, they will be available at the wiki page: http://www.haskell.org/haskellwiki/ZuriHac2015 Registration is not yet open, we will send an additional announcement email when it's open. We look forward to seeing you there! -- The organisers of ZuriHac 2015 Gleb Peregud Simon Meier Johan Tibell Alexander Bernauer
