Scalex looks like a "new" mini language server designed to provide context to LLMs for better searching. Looks interesting, has anyone tried it yet? It feels like there is a huge overlap with Metals 2. https://github.com/nguyenyou/scalex #scala

Another piece of the puzzle has been updated to Scala Native 0.5, this time it's fs2! 🎉 Now let's wait for http4s, skunk and weaver to join the party! ⌛ https://github.com/typelevel/fs2/releases/tag/v3.13.0 #scala

I'm currently working on a tiny library and the truth is, that at least 90 % of the code are bridges to a different json codecs and db backends. And I haven't even started with the ZIO interop 🤷 I also don't want to have a full-fledged effect system baked in the standard library, but just imagine the developer experience if cats-effect and ZIO shared a single, unified API! https://medium.com/@w.pitula/rage-against-the-plurality-o… #scala

Scoverage is one of the first plugins I add to any new project. The compiler team finally did the same and found some breakages - but they're already fixing them! 👏 Hopeful that Scoverage in Scala 3 hits full parity with Scala 2 very soon.🤞 #scala https://scala-lang.org/blog/2026/03/11/scoverage.html

I'm trying to implement Noel Welsh's better encoding, but I'm not sure if it's suitable for such a small library. Also, I honestly don't think I fully understand it! 😀 I would appreciate any comments or feedback. 🙏 #scala

http4s is a backbone for many mission-critical systems. I'm pleased to share that "Pure functional HTTP APIs in #Scala" by Jens Grassel is free once again, and this time it's for good! 📖 It's a fantastic resource for anyone looking to build robust, battle-tested web backends. https://leanpub.com/pfhais

Cats Effect v3.7.0 is officially here! 🎉 We've been waiting since the RC dropped back in July 2025 and it finally brings what we wanted: support for Scala Native 0.5. 🚀 What does that mean? Full multithreading on LLVM! ⚡️ The changelog is absolutely massive, go read it for yourself 👇 https://github.com/typelevel/cats-effect/releases/tag/v3.7.0 #scala

The milestone v1.0.0 release of the zio-spark wrapper has landed! 🎉 Featuring a major migration to Spark 4. https://github.com/guizmaii-opensource/zio-spark #scala

Hey FP enthusiasts, if you don't have plans for June 15–18, you have two options: 1️⃣ You can be my emotional support when my second son is born 👶, or 2️⃣ you can visit Elm Camp in one of the most beautiful cities in Czechia 🇨🇿 https://elm.camp/ #elm

Metals just dropped the standalone MCP server! 🚀 #scala Not opening an editor is becoming a standard these days. If you live in the terminal, your DX just got significantly better! This release also brings some highly pragmatic quality-of-life updates: ✅ Explain feature - access detailed errors on the fly without touching your build definition ✅ Shut down Bloop directly - no more zombie processes ✅ Twirl templates - proper support for the Play Framework Check out the full release here: 👇 http://scalameta.org/metals/blog/2026/03/03/osmium/

☝️Migrating to sbt 2 is going to be the biggest challenge this year in the Scala ecosystem. Major build tool bumps are historically brutal, but luckily, you don't need to rely entirely on LLMs to rewrite your sbt plugins. 💡You can use this new sbt2-compat plugin to help with the breaking changes and cross-version publishing. https://www.scala-lang.org/blog/2026/03/02/sbt2-compat.html #scala

This article asks the hard questions about when data science teams should stop pretending and just write Scala. Worth a read if your data pipelines are outgrowing simple scripts. At what scale do you make the switch? 🤔 https://www.scalateams.com/blog/scala-program-used-for-da… #scala

📖 A new book by Noel Welsh is in the making. Read a preview about the approaches to dependency injection in FP and OOP to fully understand the connection between them. 👇 https://buttondown.com/functionalprogrammingstrategies/ar… #scala #functionalprogramming

The stabilization milestone in form of Scala 3.8.2 is officially out. 🚀 Are you already running the 3.8 branch in production, or have you been waiting until the edges smooth out? #scala

So I tried the new Scaladoc static site generator... The verdict: mdoc is dead ☠️ Zero TypeScript or Node boilerplate. Unlike modern JS-heavy generators, you don't need a local dev server just to see a preview. You can literally open index.html right from your file system and almost everything works. (Except the search, of course.) #scala
