Scala isn't fun anymore
The author is the creator of Monix and implemented the first version of cats-effect. He knows what he is doing.

How many of you are using Monix?
I haven't had the pleasure to use it personally, but will probably check it out once Monix switches to CE3. As far as I'm aware, this requires a major rewrite of the library: https://github.com/monix/monix/issues/1502

Alternative to RxJava/RxScala
The Observer is a bit different, it returns Future[Ack] for built-in back-pressure. We can Continue / Stop synchronously or asynchronously.

What languages have "implicit awaits" ?
cats-effect or monix or ZIO for Scala.

Ruby's private keyword is weird
Thank you for sharing!
It looks like the Scala project found allowing protected[this] fields as an escape hatch for variance to be unsound:
https://github.com/scala/bug/issues/7093
Going to have to chew on that and what it means for the same feature in Sorbet…
Thanks again for bringing this up!

how to setup scala
I have a new windows 10 and downloaded the Coursier installer from scala-lang.org, the https://docs.scala-lang.org/getting-started/index.html says that you should have either java8 or java11 installed but most tutorials online and posts says to install latest version of java, which java jdk version should I install or does Coursier install it for me or do I choose the latest jdk (java-jdk-19)?

Languages That Don't Dogfood 🤔
Scala
- Immutable Map in a var, or mutable Map in a val?
-
Scala isn't fun anymore
All of those dependencies are Java dependencies, not Scala libraries, except for one, and it's a known problem that is to some extent solved already and should be fully solved very soon. https://github.com/scala/bug/issues/12632

The “Either” Issue
I had met the core developers, we had discussing a lot about which technology would better address our demand and, after many considerations, we had chosen Scala.

Next programming language?
i like scala. it combines object-oriented and functional programming into one high-level language, which makes it fun to learn. i don't know if it is popular in the robotics industry, but it runs on the jvm and can be combined with java, so there is that. i recommend the book "programming scala".

Scala REPL error when scala3 & scala 2 implemented with coursier installed with homebrew
See https://github.com/scala/bug/issues/12491 for info and workarounds. A fix will land in Scala 2.13.8.
