What is ZuriHac?

ZuriHac is the biggest Haskell Hackathon in the world: a completely free, three-day grassroots coding festival organized by Zürich Friends of Haskell. It features fantastic keynotes, interesting tracks, and of course lots of hacking and socializing!

When and where?

ZuriHac 2020 takes place Friday 12 June to Sunday 14 June and is hosted at the HSR Hochschule für Technik Rapperswil. This modern venue is located right at lake Zürich and provides space for 500 participants.

Who can attend?

Everyone! We will have a dedicated beginners' course, and there will be mentors and Haskell gurus on site whom you can directly approach during the whole event with any Haskell-related question you have.

Add to your calendar: iCal or Google Calendar.
