Ever wonder why you can't just override #sbt settings in a task? They're immutable, but there's a workaround 👀
Wrote up a quick #TIL on using `Project.extract` to run tasks with custom settings. #Scala

it is impossible to generate code comments from source code because good comments are definitionally based on things not in the source code (intent, counterfactuals, experiments, etc.)

Fantastic meetup yesterday! Shout out to the organizers and speakers for putting it all together. It was like looking into my CV: first job - Futures, next job - Actors, then monad transformers, and now tagless final. 😂

Good morning @lambdadays.bsky.social!
Today, together with @michal.pawlik.dev, we will go through the history of Scala: there will monads, transformers, actors, singers and the meaning of being in a startup!
Come coin us in Track 2 @13:30!

With our new Scala MCP server we are able to eliminate hallucinations and unproductive guesswork for code that LLMs aren't familiar with by exposing API shapes from the caches of Metals and the Scala compiler.

Two great talks on building languages at #LambdaDays 2025:
Nicolas Rinaudo will show you how to create a programming language from scratch and level up your tools and #DSL. 💻
Zainab Ali will treat docs like code, improving your workflow. #Racket #Elixir #Scala 📝

Just added slides for my talk "Tagless Final for Humans" to my page of talks:
noelwelsh.com/landing/talks/
I gave this talk today at @scalar-conf.com. The core is a new encoding for tagless final in Scala, which makes much better use of Scala's features than the standard encoding.
