#Kotlin is better than #Scala for dealing with nullability. #Java has JSpecify & upcoming support for null restrictions. In Scala we rely on social conventions (Option), while the type system is YOLO on `null`. And Scala 3's -Yexplicit-nulls is flawed. contributors.scala-la...

Hello, Currently, under the normal type system, Null is a magical type. It’s not really a class (despite how it’s presented in the doc. It has special rules to make it a subtype of every reference class type. This is illustrated by the following class diagram: Under -Yexplicit-nulls, Null is less magical. In the core type system, it is almost a regular class (with a single instance null), which extends Matchable (and hence Any). There are no special subtyping rules in the core type system f...

I really like Spine from @opensavvy.dev and @ivcanet.bsky.social. It offers a really cool and ingenious way of defining typed endpoints in #Kotlin for #Ktor that you can share between the server & client! 🔥 It just moved into beta with the 0.11.0 release. Check it out. spine.opensavvy.dev
