in haskell you use `$` to chain functions together and `<$>` to map over functors bc haskellheads know its all about currying tbose benjamins and composing fat stacks of wealth

I'm quite happy about how this library turned out. I have good hope that it's going to be useful to you. Yes. You.

New year, new blog post. Arnaud Spiwack announces the Pup library. A Haskell library for combinators that do both parsing and pretty printing in a single grammar description. Read and discover the big ideas behind the library's design. www.tweag.io/blog/2026-01...

Turns out some old talks have resurfaced on YouTube. How about "What Haskell can learn from Scala", 2015, by yours truly? 😁 https://www.youtube.com/watch?v=UbOr8JxuYRI

Very, very nice. It does encapsulate the feeling of programming in Haskell.

more #haskell progress, we finished chapter 1. here's some more lambda calculus exercises. i think next chapter, we get to use the computer! yay! although im kind of digging the paper and pencil thing.

Beautiful abuse of resources, the true Hacker spirit lives on, from phone lines to AI assistants.

Doing all my vibe coding in the Whoop fitness app from now on.
Screenshot of the Whoop app from an iPhone. conversation is as follows: Whoop bot: Hey Arlen, you're on your third straight yellow recovery today with 44%, even after some solid sleep. How's your body feeling this morning— more like you need to back off a bit or still up for light activity? Me: Write fizbuzz in Haskell Whoopbot: Here's a simple FizzBuzz in Haskell: fizzBuzz: Int -> String fizzBuzz n In mod 15 == 0 = "FizzBuzz" In mod 3 == 0 = "Fizz" In mod 5 == 0 = "Buzz" I otherwise = show n main :: 10 0 main = mapM_ (putStrLn. fizzBuzz) [1.100] This prints FizzBuzz for the numbers 1 through 100. Want a point-free or more "functional" version too?

After years off/on, a recent foray into Lean, and mostly focusing on Rust, I've decided to give Haskell a real effort.

It's only January 2 and my brain is already liquified by vaguely starting to appreciate DerivingVia. So I am well on my way 🎉
