Zürich Friends of Haskell

The Zürich Friends of Haskell is a club founded to foster the worldwide knowledge of functional programming, and Haskell in particular. We organise meetups and events in the Zürich area.


About us

The HaskellerZ meetup group has been around since 2011. After organising many meetups and events, in particular ZuriHac, which attracts people from all over the world, there was a need to formalise our group a bit more.

In the short term, this allows us to work together better with sponsors for ZuriHac. In the long term, however, we would like to guarantee the long-time success of a Zurich-based Haskell interest group, not dependent on one or two key volunteers.

The rules are set up so that we encourage non-monetary contributions (e.g. giving a talk). Of course, membership is optional and not required to attend any of our events.

Become a member!

For members, we ask a yearly contribution of either:

  1. giving at least one talk at the Zurich HaskellerZ meetup,
  2. helping organize ZuriHac in an official role,
  3. serving on the board of directors for the Zurich Friends of Haskell, or
  4. providing other voluntary work asked for by the board of directors.

Sign up for Membership

Occasionally, we reach out to our members with volunteering opportunities. Also, once a year we would send you an email to confirm and update the membership.


HaskellerZ meetups

The next meetup takes place Wednesday 3 June, 17:00.

(External) Evan Czaplicki: Making Web Apps can be Fun!

Dear members of HaskellerZ

I am pleased to invite you to the following guest lecture from the creator of the Elm programming language, Evan Czaplicki. Please note that it is at the OST campus in Rapperswil.

Title: Making Web Apps can be Fun! How to use Functional Languages at Work.

Speaker: Evan Czaplicki

Date & Time: 03.06.2026 17h15-19h00 Place: OST Campus at Rapperswil | Lecture Hall 5.002

Abstract: Typed functional languages have had success in some surprising places. From high frequency trading at Jane Street, teaching physics and engineering at Brilliant, and plenty of businesses in between. We will go through some case studies to build an intuition for why a functional language is likely (or unlikely) to succeed in a given business scenario. From there we will dive into Elm (https://elm-lang.org), a simple functional language that runs in browsers. If we have time, we will build a little website together. You should come away from this talk with (1) the core knowledge needed to build your own functional front-end and (2) an intuition for when it is a good business idea to do so. You do not need to know functional programming to enjoy this talk.

Speaker Bio: Evan is the author of the Elm (https://elm-lang.org <https://elm-lang.org/>) and Acadia (https://acadia.engineering <https://acadia.engineering/>) programming languages. He has been developing compilers and servers in Haskell for nearly 15 years, and has significant expertise in using low-level techniques to get the best possible performance out of Haskell programs.

I look forward to seeing you there!

Best regards, Farhad Mehtan Prof. Dr. Farhad Mehta

ZuriHac

Our main yearly event is the organisation of ZuriHac, a yearly Haskell Hackathon that attracts over 300 attendees. It is probably one of the oldest and definitely the largest Haskell Hackathon currently in existence.

The first ZuriHac was organised in 2010 at the Zürich Google office by Johan Tibell and Christophe Poucet. Currently, we are organising it at the Rapperswil-Jona campus of OST, with the help of many Zürich Friends of Haskell members and volunteers.


Videos

We try to record all of our meetups and keynotes so Friends of Haskell who are not in the Zürich area can enjoy the content as well.

This playlist contains all our Haskell-related videos.

We have also collected the slides of the presentations in this repository. Unfortunately, the collection is currently incomplete.


Donations

All our events are free to participants. In order to cover our costs, we accept individual donations as well as corporate sponsorships. For more information about sponsorships, please contact us at [email protected].
