The release candidate of Kyo 1.0 is a huge success, and as Flavio wrote, it's a significant evolutionary step in Scala. But remember, based on the last survey, only about 30% of commercial projects have migrated to Scala 3 😬 #scala

Put project related configuration/files into .config directory · Issue #3775 · VirtusLab/scala-cli

Is your feature request related to a problem? Please describe. I propose scala-cli relocates its project-specific files from the root .scala-build/...

Turns out there is a dot-config initiative that promotes using the existing XDG standard. Basically, all the user settings go to .config, and all the temporary files go to .local. Can you help us @intellijidea @vscode @zed ? 🙏

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
