Hello everyone, Two years ago I created get-tested, a tool that reads your cabal file, extracts the tested-with stanza and produces a test matrix for GitHub Actions. It has served me well to this day, but it also recently received a very useful contribution from @turion, who wrote a reusable Github Action for it! I am extremely...

In this edition of our “Haskell in Production” series we interview Jeroen Bransen from Chordify, an online platform, which turns any music or song into chords. Jeroen has been working at Chordify since 2016. We discussed how Chordify ensures the correctness of Haskell code and scalability of its codebase, which libraries...
In this episode, Andres and Matti talk to Mike Sperber, CEO of Active Group in Germany. They discuss how to successfully develop an application based on deep learning in Haskell, contrast learning by example with the German bureaucratic approach, and highlight the virtues of having fewer changes in the language.

A circular program is a program that depends on its own result. It may be surprising that this works at all, but laziness makes it possible if output becomes available sooner than it is required. In this final episode of 2023, which will be longer than usual (probably 45-60 minutes), we will take a look at several examples of...
The Haskell Symposium is a two-day workshop co-located with the International Conference on Functional Programming (ICFP). In a previous blog post we discussed the Haskell Implementors’ Workshop (HIW), which is another Haskell-workshop co-located with ICFP, but unlike HIW, the Haskell Symposium is a scientific workshop with...
Welcome to the comedy of errors that is our tale of four tumultuous, yet rewarding, years deploying Haskell in a production environment at Scarf...
In this episode, we are joined by Rebecca Skinner. She talks about her new book, Effective Haskell, which takes you from list manipulation to thunks to type-level programming. She also tells us about large scale industrial applications in Haskell, and how the architecture is shaped by the organization of the engineering teams.

In this episode, we'll see how deriving-via can be used to capture rules that relate type classes to each other. As a specific example, we will discuss the definition of the Monad type class: ever since this definition was changed back in 2015 in the Applicative Monad Proposal, instantiating Monad to a new datatype requires...
Andres and Wouter interview Edwin Brady, most famous for his work on the Idris programming language. We talk about how he got interested in programming with dependent types, his thoughts on dependently typed programming in Haskell, and his vision for Idris.

Lennart Augustsson gave a talk in the FP seminars at Chalmers, Gothenburg, about his new MicroHaskell....
Adds a linear fat arrow %1 => this is meant to greatly improve the ergonomics of some of the APIs using linear types (it tends to apply to APIs based on typestate or related to mutation)....
I have started the process where the GHC Steering Committee decides if we should have a GHC2024 language edition, and what it should contain. @MangoIV rightfully reminded me that when we laid out the process three years ago, we said we’d hold a community poll as well....
The Haskell Cryptography Group is glad to announce the first public release of our low-level bindings to libsodium....
