What's the point of Bloop if sbt, mill, and scala-cli already support BSP? #scala

I'm so glad that I left web development around the era of jQuery. #html #css #javascript

Is there also a handler for the error side? Something like Either's leftMap? #kotlin

A new static site generator 📖 made with Scala 3.7! This is what convenience looks like. Case classes use derives, but you can also find vars here and there... #scala

Really looking forward to the debugger support in Zed for Scala! 🚀 #zed #scala

Feature Request: Add support for Debugging · Issue #53 · scalameta/metals-zed

Zed recently introduce support for debugging: https://zed.dev/docs/debugger Our favorite programming language is not yet in the list: https://zed.d...

So, zero allocations and zero dependencies. And it uses byte arrays and pointers instead of match types, named tuples and opaque types... Interesting 🤔 #scala

Not sold yet, I will probably need more real world examples 🤷 #scala

Back in the days when I worked as a "data engineer", we had two teams. One used a GUI to create pipelines, and the other built a custom Scala app to do the same, but with all the perks like config in git, CI/CD, tests, etc. At first, the GUI team was much more productive, but guess what? After some time, their system started to become messy and hard to manage. Our team, on the other hand, had been able to deliver features steadily by just adding things to the config. This feature 👇 looks like it combines both approaches. #spark #databricks

Let's look at how a typeclass can be implemented in Kotlin with context parameters, and how you can achieve the same result in Scala. #kotlin #scala

Looks like Kotlin's implementation of implicits is becoming a reality. I think the community doesn't realize that this feature changes Kotlin forever, even though it's still experimental and bare bones. #kotlin

This kind of reminds me of Smithy, which is also able to specify types and methods in a pseudo-language and generate a working API.
