Slick, the Future-based database library, will soon get a massive update with version 4! 🚀
It's ditching the Future-only constraint for a new Cats Effect 3 engine, bringing dedicated facades for Future, IO/fs2 and ZIO. All with the same query DSL.
#scala github.com/slick/slick/...
It is heavily inspired by Jamie Thompson's presentation last year about named tuples and it is built directly on the new named tuples feature introduced in Scala 3.7.
I will get back to it again after I try it by myself, but the compile-time safety looks amazing. 👏

Zero-cost, type-safe Spark data pipelines! 🚀 No, I'm not talking about Frameless, but Wick: an internal tool from Netflix which has been open-sourced! Huge credit guys for sharing this with the community! ❤️ #scala

Do you use if guards in for-comprehensions? You don't, right? They are practically unusable. ❌ This pre-SIP discussion wants to change that, and from the first draft, it looks very promising. This would increase our everyday quality of life significantly!

Skunk v1.0.0 was released 🎉 This one is packed with the good stuff!
✅ Scala Native 0.5 support
✅ otel4s replacing Natchez
✅ A new fluent API for building sessions
✅ Unix domain sockets & peer auth
👋 Scala 2.12
Smoke out the full changelog! 👇

"I have to warn you: you'll actually fall in love with this language very quickly. It's really easy to use and makes so much more sense than Java in a lot of ways."

For all the curious #Java developers out there, here is a quick look at how to use Scala 3 with Spring Boot. But as the author says:
It breaks down the foundations of OpenTelemetry - covering traces, metrics, logs and context propagation and how otel4s brings these concepts into the purely functional Scala world using Cats Effect 🐱

The only article (well, it's actually a series) about observability you need to read! Recommended by Azuros Cloudapi to both Java and Scala camps! 😂 #java #scala
A cool new CLI tool which helps you discover running Scala-related processes. 📈
It would be awesome if it had an interactive mode so I could kill those zombies right from it! 🧟♂️ #scala
That's exactly what Kindlings does. Currently it can replace derivations for libraries like Avro4s, Jsoniter, PureConfig or Tapir. Time to give it a test run! 🏃

Imagine you could derive an Encoder for both #Scala 2.13 and Scala 3 without Shapeless or Mirrors. All with just one API, faster compilation and better error messages. 🤯 (<- the only appropriate reaction to this)
http4s 0.23.34 is out 🎉 #scala
The Typelevel stack is now almost completely on Scala Native 0.5:
✅ Cats Effect
✅ fs2
✅ http4s
✅ Weaver
❌ Skunk

Anyway, if you have some spare tokens, consider helping out the ones that aren't quite prepared yet! Check the status and see where you can contribute 👇

I know I've posted about it several times, but sbt 2.0 is truly just around the corner! After checking the list of plugins that are already cross-published, it looks like we're gearing up for a very smooth migration. 🤞 #scala
Metals v1.6.7 is out! 🚀
Thanks to @michal.pawlik.dev , the MCP server now supports stdio! What does this mean for you? No need to run a standalone MCP server in a different terminal and no need to configure HTTP ports anymore! Great job! 👏 #scala

Nowadays, I can't keep up with the ecosystem tempo - every day a new article, a new library, a new release with dozens of new features.
To quote the article: "The cost of complexity drops, but the value of strong abstractions remains." 🧠💡

I was afraid that I'm the only one who feels the huge traction and positive vibes in the last 2-3 months! ❤️
Because let's be real, the last couple of years in Scala were very hard and a lot of people left. But the sentiment changed, I feel it in the water. (I smell it in the air.) #scala
(3/4) pgmq4s brings that simplicity to Scala. It features
✅ Typelevel ecosystem
✅ Multiple backends
✅ Multiple JSON codecs
✅ Cross-platform - Skunk backend + Circe/Jsoniter/uPickle codecs work on JVM, JS, and Native
🚧 Streaming - currently work-in-progress
(2/4) The question is - do you really need Kafka's performance if you already use Postgres? Imagine being able to debug messages with standard SQL, re-order or edit messages in place, or even join your queues directly with regular tables.
My other passion (besides Scala) is databases. There is an extension called pgmq, a message queue built on top of Postgres which can cover the scale for 99% of companies. To connect the two passions, I'm building a Scala client called pgmq4s. 🧵 #scala
Scalac is starting a new blog series for managers and engineering leaders. 👔
It's great that it isn't just another news aggregator, but instead focuses on real architecture lessons and trade-offs. After all, if people just want news, they could just follow me! 😀 #scala

I'll be totally honest - I got lost somewhere in the middle of this article 🤷 But if you are up for some advanced type level shit, this is for you 👇 #scala

Speaking of Actors, there is a new research paper which tries to solve a problem when you need a combinations of messages to trigger a specific task.
The paper introduces JoinActors, a macro-based library for Scala 3 that brings guarded join patterns to the actor model. #scala
Cats-Actors 2.1.0 just went cross-platform! 🚀
Choose JVM for throughput, Scala Native for instant startup or Scala.js for the browser.
