Two astronauts float in space, looking at Earth. One astronaut, closer to Earth, faces away and looks at the planet, which is labeled with the text: “Everything is just Function, Kleisli or FunctionK composition?” Behind them, the second astronaut points a gun at the first and says, “Always has been.” The image is the well-known “Always has been” astronaut meme, used here to humorously suggest that software architecture and programming abstractions ultimately reduce to function composition.

A Reddit post in the r/scala community from user “sideEffffECt” posted 2 days ago. The post announces a remote job opening: “Hiring a new Scala Software Engineer with TypeLevel experience, Full Remote ($87K – $138K).” It includes a job link (ashbyhq.com), a bullet list stating:
	•	Full remote
	•	Stack includes Scala, Cats Effect, microservices, GCP, Postgres, Kafka
	•	“I’ll be happy to answer any questions”

A note at the bottom says:
“The salary range for this role is between $87K – $138K • Offers Equity • Final compensation is determined by experience, skills, and location.”

We all need to unionize against this crap. #Scala is arguably not as easy as #Kotlin or #Java. Lay on top of that, knowing the intricacies of all the typeclasses of #Typelevel Cats Core, and then on top of all that, add all the concurrency typeclasses of Cats […]

[In which Gemini hallucinates Functor[Set]]

A conversation with Gemini 2.5 Pro about which instances Typelevel Cats provides for `Set`. Most of this output is plausible, on a challenging subject. But it's wrong from the start, and it repeatedly rejects correction […]

#Spotify has donated €20,000 to #Typelevel 👏 — they're using & contributing to #Scala and in my eyes, it gets extra points for being an EU company, besides being the best music streaming service 😉

Has anyone compiled a #Typelevel #Scala starter pack yet?

On #Scala's #CatsEffect library — one common myth is that it's a library built for “tagless final” (TF).

While it's true that it gives you unparalleled ability to use TF and monad transformer stacks, it's perfectly usable without. Most libraries from #Typelevel are.

New #Typelevel “code of conduct”. Changes seem good b/c #CoC is now more explicit, but I hope it's battle tested. E.g., it has enforcement + a section with “inappropriate behavior” (also listing doxing & harassment) 👏
