Today, Matthías and Joachim are interviewing Moritz Angermann. Moritz knew he wanted to use Haskell before he knew Haskell, fixed cross-compilation as his first GHC contribution. We'll talk more about cross-compilation to Windows and mobile platforms, why Template Haskell is the cause of most headaches, why you should be...

Avi Press gave an excellent talk at Scale By the Bay 2023 about difficulties using Haskell at a startup. He mentions that even experienced Haskellers don’t always know how to use fundamental parts of the language. In particular,...
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.

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...
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.

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....

Joachim Breitner and David Christiansen interview John MacFarlane, a professor of philosophy at UC Berkeley, but also the author of the popular pandoc document conversion tool, which has been around half as long as Haskell itself. He also explains the principle of uniformity as a design goal for lightweight markup languages, the...
Hi everyone, The Cabal development community is sending a call for participation in our quality assurance (QA) programme. We are looking to improve the quality of the software we ship on the Windows platform.
