"Patterns and Paradoxes: The Logic of Pattern Synonyms" by Koz Ross www.mlabs.city/blog/pattern... #Haskell

"Cheaper: producing a program with less developer time" by Alexandre Esteves: github.com/alexfmpe/sem... #Haskell

Who vibechecks the vibe coders?

Now imagine the discourse if Debian started mandating working Haskell toolchains on all platforms 🤭

"Case Study: Debugging a Haskell space leak" by Matthew Pickering from Well-Typed www.well-typed.com/blog/2025/10... #Haskell

Happy halloween I guess

Can Haskellers in Seoul snap a pic with the CEO of Nvidia? We need some ₩ before the bubble explodes.

New episode of the Func Prog Podcast! In this episode I interview @tritlo.bsky.social—we cover Haskell, LLMs, program synthesis and, of course, deadlifts! Listen below 👇

Sorry for having betrayed your trust… We thought the inherent safety of our language would be enough, but manifestly it isn't. We'll learn and grow from this. >_>

GHC 9.14.1-rc1 is now available. This includes an important fix which ensures compatibility with macOS 26 and later. This fix will be backported to GHC 9.12 and 9.10 in the coming months. Happy Haskelling! https:/ /www.haskell.org/ghc/blog/20251030-ghc-9.14.1-rc1-released.html #Haskell

In the new Haskell Interlude, we talk to Manuel Chakravarty - his work on the ghc backend such as data-parallel Haskell and the FFI and how that work segued into type system design. We also discussed Manuel’s perspective on Haskell from the design of Swift. haskell.foundation/podcast/72/

Yes it's called Haskell, next question.

We're cooking something with @upcloud.com, stay tuned

🎉🎉🎉

Someone gets it!

Nice.

literally salivating at the idea of interactive Haskell slides for programming language theory classes

This is awesome!

Great news!

This is not a drill: GHC (the #Haskell compiler) now runs in your browser. See the announcement (and please report any bugs) here: discourse.haskell.org/t/ghc-now-ru...

Not around these parts. ghci> import Data.Text.Encoding.Base64 ghci> isBase64 "unused" False flora.pm/packages/@ha...

Prediction: The next batch of successful #Haskell developers will not be using LLMs that have been trained on decades of open-access Haskell code. Far from every snippet found on online code forges is good quality. Upskilling goes through learning in a certain environment with local experts.

Calling for the separation of Church numerals and application State.

Partial Ordaining, because some numeric churches don't recognise your authority.

Yesterday we hosted the very first edition of Func Prog Conf, and I'm very happy about how everything turned out! The speakers all delivered stellar performances and the mood was great. I hope everyone enjoyed the "hallway track" as much as I did!

Legend.

Everything is Haskell if you squint hard enough. But nothing is as good as the real thing.

Programming languages of the ML family are often heralded as having powerful type systems that allow them to model the complexity of the real world, in a way that is less bad than the competition. The potential absence of a value is described not an implementation detail due to an undefined/null…

The mad lads have made it: Two Haskellers went to the town of #Haskell, TX. They documented their journey here: www.youtube.com/watch?v=9KwW... See on Reddit: www.reddit.com/r/haskell/co...

Shout-out to a reliable and solid piece of software engineering in the #Haskell ecosystem: atomic-counter. A thread-safe, optimised package that provides enough of an API to be useful for when you need to manipulate a counter in a multi-threaded application. hackage.haskell.org/package/atom...

What do folks out there do for error handling in concurrent tasks in #Haskell? For now I've settled on having an error `TMVar`, then use a `ki` structured concurrency scope which forks all my jobs and ends in an `(Right <$> awaitAll) <|> (Left <$> readTMVar errVar)`

Let's goooo

Congratulations Jan!

If anyone hasn’t read it yet, I recommend effective Haskell. I’ve not finished it. But so far so good. #cpd #haskell #functional

New blog post! #Haskell is built on a foundation of Monads, but are they really the optimal way to sequence effects or should we keep looking for something better? What's the big deal with Applicatives and Selective Applicatives? Read on! chrispenner.ca/posts/expres...
