Really excited to announce this! @Alang9g and I have been working on a non-Euclidian puzzle game for a while, and it’s finally ready! Please give it a try and if you like it, please share it on, it’s completely free! sokyokuban.com/

Turbo Haskell (public release announcement)

“More formally, one could say that X” only states that X is more formal than the preceding, and that some rando could say it, but not that it’s formally correct. This makes it a perfect match if you want to impress with some fancy words, but you’re not like, 100% sure

I'm proud to announce my new book: Soar with Haskell.
I've packed 20+ years of programming, teaching and researching Haskell in this book to help you take off.🦅

I believe I fix most of the annoying bugs in Haskell websockets library except for the "not enough bytes" that I still don't have a reliable way to reproduce.
If someone does, let me know and I'll fix it!
have been playing with Scheme a bit. people always make fun of the parentheses and I think that's a bit sad because the caadar/caadddr/... stuff is way funnier
added slide transition effects to patat github.com/jaspervdj/patat/p…
Added "proper" support for speaker notes to patat. Pretty happy with how simple the idea is! No need to practice slides anymore, just scribble down some comments and call it a day 😎

ZuriHac 2023 will take place 10-12 June at the same great location as last year! We have an amazing speaker line-up for this year and there'll even be a co-located GHC event! 🥳💻 More info and (free!) registration at zfoh.ch/zurihac2023/
The Haskell homepage now lists a single recommended way of installing Haskell. This makes things a lot less confusing for beginners and unblocks many other improvements. Big kudos to @tomjaguarpaw for making this happen!
