You recently struck a deal with the U.S. Defense Department to deploy AI models on their classified network. What kind of ethical safeguards have been implemented? They will not be allowed to use the Studio Ghibli filter on prisoners of war.

The Onion’s Exclusive Interview With Sam Altman theonion.com/the-onions-exclusive-int...

Added scalajs and scalanative support, and publishing locally and to maven central!

Please take a quick 5‑minute survey on Scala adoption and usage. Results will impact Scala’s roadmap, libraries, and tooling. Help shape the future of Scala!

Brought to you by VirtusLab and the Scala Center.

Survey: virtuslab.typeform.com/ScalaSurvey...

We're running the 2026 #Scala Survey!

Let us know how you are using Scala, #AI with Scala, and give hints to the Scala teams (both at VirtusLab and EPFL) on where the focus in driving Scala forward could be.

Thank you - your answers count :)

And are you really sure it is a needle tho?

Scala lang cant be this evil!!??

Nice Try :)

Most jvm build tools are weird in that space.. especially if used with daemon server

Someone's added APE (Actually Portable Executable) support to the GraalVM AOT compiler for Java. So now it is possible to AOT compile Java to a single binary that runs on MacOS, Windows, and Linux on both x86 and ARM!

Regenesca - Refactoring Generator of Source Code for Scala “Refactoring Generators” is an interesting approach to generate scala source code. And not only that, but it will also refactor your code if it needs to. Think “git merge” but for scala code. Think scalafix but rules are per file, not global. Core library that does the diff+merge: https://github.co

✨ Large codebases don’t refactor themselves. This session explores Regenesca and how automated source-code refactoring can help keep Scala projects maintainable.

Check out how to create a small build tool:

#scala #java #sbt #mill #maven #gradle

GitHub - sake92/deder: Config based client-server build tool Config based client-server build tool. Contribute to sake92/deder development by creating an account on GitHub.

Made a small build tool just to see how far I can get.
github.com/sake92/deder

It can compile scala/java, import in IDE via BSP, run tests, run main classes (even in multiple terminals at same time), has watch mode etc.
Main goals are stability, concurrency and simplicity.

I have used Classycle to analyze classes deps. Turns out it also works on packages level too.

That ancient version probably doesnt work, so try my forked one. It is on maven btw

Sharaf 0.14.0 is out!

github.com/sake92/shara...

Added support for:
- SSE
- named tuples in query/form params
- union types in query/form params

Do it! 😁

Check out my post about writing a simple lexer, parser and an interpeter from scratch. Beginner friendly, with lots of examples.

There is no typo 😝

How does your "perfect" build tool looks like?

Apart from:
- it works reliably and correctly
- performant/parallel
- resources aware, not hogging cpu/memory

Hello world!

In scala arrays are invariant because they are mutable, so following java would be error prone. Immutable collections are covariant because it is safe, you cant mutate its items in place.
