released sbt 1.11.0-RC1 featuring the Central Repository publishing support

I actually haven't converted to new portal, and only tested upload part, so if someone has an account with namespace attached, plz let me know if the releasing works

This looks interesting/promising.

"Simple, Composable, Business-oriented Workflows for #Scala"

business4s.org/workflows4s/

It is heavily inspired by temporal.io, which I also found interesting/promising but could not figure out how their JVM thread suspension magic would work with our favourite functional effect systems.

Workflow4s works without any central orchestrator (just relies on a shared database and on Quartz for scheduling).

Je viens de découvrir grace à cette vidéo youtu.be/p1kdUISc_WM?si=EzLChT les dernières évolutions de #scala et aussi de #scalacli. C'est vraiment top. Je termine une mission avec de réécriture d'un projet en #scala 2 vers du #java qui m'avait un peu réconcilié avec ce language. Mais la j'ai vraiment envie de me remettre au #scala après avoir visionné cette présentation. Si votre vous avez des projets n'hésitez pas.

@profoundlynerdy just because something has types doesn’t make it Haskell-like. Haskell’s type system is in the family of Lambda Calculii (the “Lambda Cube”) which is called “System-F”.

I don’t know much about Raku, but it seems to me to me to be a bit more similar to TypeScript. And what differentiates TypeScript from other languages: it takes a horrible programming language like JavaScript and makes it less bad by giving it a type system, likewise Raku makes Perl less bad in the exact same way. (Sorry, I’m not trying to be impolite, but JavaScript and Perl are objectively, truly awful, horrible programming languages.)

So I see both Raku and TypeScript only being useful to a company buried in the technical debt of a hugely profitable production application that was very unwisely written in a dynamically typed language (Perl or JavaScript), which then unfortunately grew to millions of lines of code, and now it can’t be maintained by anyone, and it could never possibly be rewritten from the ground-up in a good programming language like Haskell for any reasonable sum of money. So Raku and TypeScript both offer a half-measure solution to that problem: make the maintenance of horrible computer code a bit easier with a type system.

Haskell was never intended as a fix for horrible code, it took a really good experimental programming language called Miranda and turned it into something that you can use to do real, practical software engineering, and it does it better than any other language ever invented. You write a system in Haskell because you know up front that you want it to be stable and maintained in a cost-effective manner for decades.

Zig is not similar to Raku or Haskell. It is more analogous to what Scala does for Java. Java is already statically typed, but Scala’s type system is better, and it’s runtime is fully compatible with Java. Likewise, Zig is fully compatible with the C language runtime, but provides a slightly different, slightly better static type checking system than the C type system. Zig also solves a bunch of other problems that C has by providing it with modern features like namespaces and modules, which makes it much easier to use than C. Zig is the perfect way to replace old C code with something more modern, but only if you don’t need it to be as rigorously correct as Rust. I think Zig would be a nice language to use to replace non-safety-critical front-end libraries like Gtk, or maybe for things like game engines.

Next time you hear there are no advantages to upgrading to Scala 3, feel free to share those examples 👇 #scala

I just released #⁠fs2-data 1.12.0, bringing nicer and safer operators to work with XPath and JSONPath streams. See the changelog at github.com/gnieh/fs2-data/rele #scala

Have you heard about Weaver? It's an extremely performant test framework built on top of Cats Effect and FS2, originally from Disney Streaming. #scala disneystreaming.github.io/weav

If you think scala-cli is only good for sharing bug reports, you should play with it for some time or look at this video. It's actually a super powerful and versatile tool! #scala youtu.be/TcKRe-sTJQY

After spending a couple of days with Nix, I found out that it's probably not for me. 😀 It's too much hassle for my use case. I decided to write a simple Scala CLI script on top of Brew and Stow instead. 🤷‍♂️ #nix #scala #brew #stow

Finally got around to watching the Professor's talk from the latest Scalar Conf on "Evolving #Scala". One thing that really made my arms down was the claim that the Scala compiler processes 10 KLOC per second, and that’s fast enough for the Professor (what's a legitimate point), and if it’s much slower for you — "don’t blame the compiler, blame the libraries… some libraries do crazy stuff with macros and implicit resolution… and that’s inherently slow… and there’s nothing you can do about that".
