Release Kyo 1.0-RC1: A New Era of Simplicity and Stability · getkyo/kyo · GitHub We're excited to announce that Kyo is finally entering a period of API stabilization! 🚀 Over the past three years, we've quickly iterated on the abstractions of the library to ensure they're reliab...

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 github.com/getkyo/kyo/r...

If you use one of the top 10 most popular programming languages, try Scala, you'll never look at things the same way again. But if you already use Scala, the same goes for Unison. This is a great introductory video from @etorreborre.blog 👇 #scala #unison

If you haven’t seen Kyo yet, the first ~20 minutes of this video is a nice introduction. 👍👍

For instance, you’ll learn what this syntax means:

val s: String < IO =
IO(readFile(filename))

There’s also a nice map/flatMap surprise in there as well! 👏

sbt 1.11.0 is released

Some late syntax changes are nice I guess (better `for` and type-classes) but when I read about collection literals or `into` I cannot help but feel we're focusing on problems nobody has. 🤔

i released the 2nd post, pondering the idea of ai-based coding and its potential impact on software development. this time i discuss the forces that drive the market and decision making (might feel a bit darker and more controversial than usual): www.ufried.com/blog/ai_and_...
