Hello everyone!
We are hosting the next Haskell meetup in Vienna on the 30th of April! The location is TU Vienna Treitlstraße 3, Seminarraum DE0110. The room will be open starting 18:00 and the first talk will start at 19:00.
As we are still looking for a speaker, we would be happy for anyone willing to hold a small presentation or present some work/topic they are excited about!
There will be time to discuss the presentations over some snacks and non-alcoholic drinks which are provided free of charge with an option to acquire beer for a reasonable price.
The meetup is open-ended, but we might have to relocate to a nearby bar as a group if it goes very late…
There is no entrance fee or mandatory registration, but to help with planning we ask you to let us know in advance if you plan to attend here [Vienna Haskell Meetup](https://forms.gle/2ajZ5txcZuMTg49w6) or per email at [haskellvienna.meetup@gmail.com](mailto:haskellvienna.meetup@gmail.com).
We especially encourage you to reach out if you would like to hold a talk or participate in the show&tell so that we can ensure there is enough time for you to present your topic.
Finally, we would like to thank Well-Typed LLP for sponsoring the last meetup!
We hope to welcome everyone soon!
Your organizers:
Andreas(Andreas PK), Ben, Chris, fendor, VeryMilkyJoe, Samuel

Hello!
Tomorrow will be the Haskell Vienna Meetup!
Our speaker is @simon, and he will speak about arrowized functional reactive programming (ARFP)
> The topic of the presentation is arrowized functional reactive programming (AFRP in short) with some practical examples. As part of that, a very small game will be created during the presentation. At the end, we can talk about some further AFRP concepts if time permits.
The doors will open at 6 pm, and the presentation will start at 7 pm.
Looking forward to seeing you!
Best regards,
The organisers

Is it possible to see the presentation / examples? Sounds quite interesting.

Hello, I have now uploaded the presentation slides and the examples. So you can see them by going to the link:
> **[reactimate/reactimate-game/examples/presentation-example at main ·...](https://github.com/Simre1/reactimate/tree/main/reactimate-game/examples/presentation-example)**
>
> main/reactimate-game/examples/presentation-example
The `Main.hs` contains multiple signal functions and `main` definitions, which are the examples I used for the presentation. You can run one of the main examples with `cabal run presentation-example` (you need sdl2!).
Essentially, I have shown AFRP concepts using my `reactimate` library, which is an implementation for AFRP. It is all quite experimental still (especially the game part `reactimate-game`), so I would not suggest using this for any big projects.

Is there already a date for the next meetup? I would like to know so that I can plan ahead.

The next meetup is planned to happen on the 25.6.2026, but the room reservation hasn’t been confirmed yet, so we are waiting a couple of days for the official announcement

> Compiling C to Haskell — How `hs-bindgen` Translates C Headers
There will be time to discuss the presentations over some snacks and non-alcoholic drinks which are provided free of charge with an option to acquire beer for a reasonable price.
The meetup is open-ended, but we might have to relocate to a nearby bar as a group if it goes very late…

Change of plans everyone!
Our speaker for the next meetup on the 25.6.2026 is going to be Niek Mulleners!
> Programming with Holes, Types, and Tests
>
> The duty of the compiler is to turn programs into executable code.
> When a program is incomplete or incorrect, it should tell the programmer exactly why their program cannot be executed and, ideally, how this can be fixed. To do so, the compiler has to understand the programmer’s intentions. In this talk, I will explore how programmers can express their intentions through types, tests, and sketches (programs containing holes), and how the compiler might use this information to assist them in writing programs.
We are very excited about our surprise guest and for them to present their research!
For everyone excited for `hs-bindgen`, don’t worry! We rescheduled Dominik’s talk to one of the following meetups 🙂
See you all on the 25.6.2026!

I won’t be able to make it today. Still wish you a nice time!

We are hosting the next Haskell meetup in Vienna on the 24th of September 2026! The location is TU Vienna Treitlstraße 3, Seminarraum DE0110. The room will be open starting 18:00 and the first talk will start at 19:00.

> Compiling C to Haskell – How `hs-bindgen` Translates C Headers
> C has a library for everything, and those libraries are fast, battle-tested, and maintained by somebody else. Reaching them from Haskell is the hard part: a Haskell-native rewrite is a project of its own, and hand-writing bindings is tedious and error-prone. `hs-bindgen` automatically generates those bindings for you.
> In this talk, we explore the vision and the architecture behind `hs-bindgen`: a compiler whose source language is C headers and whose target is Haskell modules. We discuss some challenges of reconciling C’s low-level memory model with Haskell’s rich type system. I hope to convince you that using a C library from Haskell is less like a project of its own and more like an afternoon’s work.
This talk is going to be similar to the one that he will give at [MuniHac 2026](https://munihac.de/2026.html#about).
There will be time to discuss the presentations over some snacks and non-alcoholic drinks which are provided free of charge with an option to acquire beer for a reasonable price.

Reminder, we meet this week on Thursday!
This is also the 2 year anniversary of the Vienna Haskell Meetup, which is awesome!
Thank you all for your participation making this meetup a success ❤
Looking forward to seeing you at the meetup!
