#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 😉

I was in charge of running a full day of Typelevel workshops they day before the conference, so I was in the middle of this.

How we, as Typelevel, handled this is one of my proudest moments of my entire life.

No notes.

I am thankful to the Typelevel community and the wider Scala community in general.

I haven’t done much Scala coding in the past few years, but been paying attention enough to know that Typelevel has a great community and great general principles for functional programming in Scala.

The Typelevel Foundation was determined to be a 501(c)(3) public charity!

This is a testament to the intellectual merit and educational value of our community's contributions to functional programming. Congratulations!

🧪 The Typelevel ecosystem has shaped how many of us write Scala today. This talk looks back at where it started, what it became, and what we learned along the way.

Hey, folks. Version 0.3.0 of #Raise4s is here 🍻 After a while, we added some interesting operators on #Scala iterables (and Typelevel Cats 🐈 `NonEmptyList`) to traverse collection with raised errors.

Check it out! 🙌

If anyone knows who else to add to the Scala Typelevel Starter pack, let me know.

I didn't find tpolecat. Maybe Rob is on a custom domain that doesn't show in search results? What about Noel and Adam?

Also, I really shouldn't be on the list. Why can't I remove myself?

GitHub's new feature to create slop issues with Copilot is handy to initiate discussions about how open source organizations need to be planning their migration off GitHub to escape Copilot's slop.
