The The Haskell Interlude just published a nice interview of @ranjitjhala by Andres Löh and Matthías Páll Gissurarson: haskell.foundation/podcast/32

A former colleague of mine is on the market. Amazingly productive developer and very pleasant colleage. Expert in PL UX (LSP etc.). Poach him while you can.

Anders Hejlsberg Anders Hejlsberg, inventor of Typescript and C#, gave a great keynote talk about Typescript at #ICFP2023. It included some type level programming!

A highly entertaining double act by Samantha Frohlich and Harrison Goldstein Harry Goldstein for their talk Reflecting on Random Generation at #ICFP2023.

At my talk at #ICFP2023 I claimed that with observable sharing one can write a parser combinator library where left-recursion works (in the presence of sharing), and someone asked if I had, and I had to admit I hadn’t, so the next day I did: joachim-breitner.de/blog/807-Left_… #haskell

Squashing your Github PR (if that’s what the project you want to contribute expects) is surprisingly annoying. So I created squasher.nomeata.de to do it for you.

Exited to start a new Job working on Lean tomorrow: joachim-breitner.de/blog/809-Joini…

I once created a #Motoko #internetcomputer canister that holds ICP tokens and gives it to whoever can guess a secret (and codes up a bunch of technicalities). Two years later, it was indeed solved: forum.dfinity.org/t/capture-the-… (I won’t reveal how, in case others want to try as well.)

We're thrilled to share that the roadmap for Lean FRO is now public! lean-fro.org/about/roadmap/ 🚀 Join us in shaping the future of Lean! #LeanFRO #LeanLang #LeanProver

Charming tweet, glad you liked it!

The GHC Steering Committee has decided on the language extensions for the next language edition, GHC2024: github.com/ghc-proposals/…

I have resigned from my post as GHC Steering Committee secretary, and wrote a little retrospective at joachim-breitner.de/blog/811-GHC_S… (If you were following me just for the notifications about accepted proposals, well, 🤷)

I've implemented functional induction theorems in Lean, shipping with the upcoming version 4.8.0, and wrote a tutorial-style blog post about it: lean-lang.org/blog/2024-5-17… (h't to David Christiansen for the tooling behind the hover features.) #lean #leanlang

Are record-breaking records more or less record breaking than earlier records? A small Sunday afternoon mathematical musing: joachim-breitner.de/blog/814-Do_su… #math #statistics

Eigentlich verteidige ich die Deutsche Bahn Personenverkehr ja, aber… Am Samstag per Rad am IC Rottweil-Herrenberg, abgewiesen mangels Radreservierung, obwohl Platz und noch in der App buchbar. Heute Retour: Abgewiesen trotz Radreservierung, weil überbucht und voll?! Dot wer zu viel Kafka gelesen?

Our latest work AlphaProof, building on AlphaZero, LLMs and the Lean theorem prover, combined with AlphaGeometry 2 managed to solve 4 IMO problems and achieve silver-medalist level! 🚀 More at dpmd.ai/imo-silver

It's so fucking awesome that Lean went from being an obscure dependently typed theorem prover that only PL theory nerds and mathcels revered to being actually useful and... mainstream? It's a really good PL. Don't take it from me, here's Graydon Hoare praising it too.

At first I thought he was wearing a theorem prover t- shirt. There were plenty of theorem prover people at the party, with a heavy focus on Lean.

In this wonderful episode of the The Haskell Interlude Lindsey Kuper Lindsey Kuper (@[email protected]) gives an interesting account of her career though industry and academia, and from the world of strict functional languages to lazy functional programming in Haskell (which involves Ryan Newton!).
