Middle of June 2019, the Zürich Friends of Haskell association will organize ZuriHac 2019, a three day Haskell Hackathon hosted at the HSR Hochschule für Technik Rapperswil. This is the eighth Haskell Hackathon organized in Zürich and and the third one hosted at the HSR. This fantastic venue is located right at lake Zürich and provides space for more than 400 participants.

The Haskell Hackathon is a completely free, international, grassroots collaborative coding festival whose goal is to expand the community and to build and improve Haskell libraries, tools, and infrastructure. This is a great opportunity to learn more about Haskell, meet fellow Haskellers in real life, find new contributors for your project, improve existing libraries and tools or even start new ones!

This event is open to any experience level, from beginners to gurus. In fact, one of the goals is to bring beginners in contact with experts so that the former can get a quick start in the Haskell community. We will have a dedicated beginners' course, and there will be mentors 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.

Beginner Info

We want to make the event accessible to Haskellers at all levels. This is why we have dedicated mentors and beginner-level Haskell exercises every year, and 2019 will be the second year to feature an introductory course by Julie Moronuki.


You can identify mentors from the black Zurihac shirt. They welcome any questions you may have, so please grab them if you have any issues or questions.

Beginner course

Julie Moronuki, the co-author of both Haskell Programming from first principles and The Joy of Haskell, has kindly agreed to teach a free beginners course for people who are just getting started with Haskell. This beginner track will run on Friday and Saturday afternoon and will not conflict with any keynotes.

In case you are interested in the beginners track, we will ask you to fill in a poll so we have a better idea of how many people will attend the track and what the level of the audience is.


The hackathon takes place at the HSR Hochschule für Technik Rapperswil. The campus is about 40 minutes outside of the Zurich city.

Oberseestrasse 10
8640 Rapperswil-Jona

The Hackathon mainly takes place in two buildings: Building 1 and Building 4. Detailed info on the different rooms will be announced later.

The venue is located right next to the lake, and weather has been superb (25°C, 77℉) during the previous years, so feel free to bring your swimming gear!

Getting there

You can take the S7 or S15 to get from the Zurich main station to Rapperswil. These trains run regularly in 30 minute and 60 minute intervals, respectively. Google maps works well for directions if you use the "public transport" tab.

If you arrive at the Zurich airport, first take the train to the Zurich main station and then continue with S7 or S15. Trains from the airport towards the city run every few minutes.


As for accomodation, there are two options. You can either stay in Zurich, or in Rapperswil itself. Both have advantages and disadvantages: there are more things to do in Zurich, but you can save time and transportation costs by staying in Rapperswil.

During previous years, attendees have also shared accomodation (e.g. on Airbnb). In order to get in touch with fellow attendees, we recommend using the #accomodation channel in our Slack chat.

If weather allows for it, camping is also a very affordable and beautiful option for the ultimate grassroots ZuriHac festival fans. Several people have stayed at this campsite in 2017 and 2018.

Train tickets

If you stay in Zurich city, the easiest option is to get a 24 hour pass for all zones. It's good for all public transportation around Zurich, up to Rapperswil. A one-way ticket costs 17.20CHF, the 24 hour pass 34.40CHF.

Please note that the 24 hour pass is literally a 24 hour pass and can be used over multiple days: e.g. if you buy one on the first day of the Hackathon at e.g. 9.00, you can still use it to take the train at 8.00 the next day. This way, it is possible to buy only two tickets for the three-day conference.

A lightly cheaper alternative to the 24 hour pass is the 9 O'Clock day pass which works more like a regular day pass. However, this requires you to take the train to Rapperswil after 09:00 on Friday, as described on the website.

You can buy tickets from the SBB or ZVV vending machines, which have a button to use them in English rather than German on the home screen. Alternatively, you can use the ZVV ticket app on Android or iOS.
