Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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)?

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.

Running the "Reflections on Trusting Trust" Compiler
The C4 compiler [https://github.com/rswier/c4] is a self-hosting compiler for a subset of the C programming language that produces executable x86 code. You can understand and audit this code in a couple of hours (its 528 lines).
It could be an interesting exercise to bootstrap up from something like this to a working linux environment based solely on source code compilation : no binary inputs. Of course a full linux environment has way too much source code for one person or team to audit, but at least it rules out RoTT style binary compiler contamination.

Flattening ASTs (and Other Compiler Data Structures)
I was surprised to see nodes still have two pointers ("references") given that you now know that that the first pointer will always point exactly to the next node. I've see https://github.com/rswier/c4 use that. Granted it doesn't make for the most readable code, but it's even smaller and faster.

vermin_vm: Virtual Machine(~400 lines) + Assembler(~800 lines) written in C
VMs with simple instruction sets is a fun topic. Some years ago I got inspired by the amazing rswier/c4 compiler by Robert Swierczek and explored the smallest instruction set I could get away with to create VMs that could run non-trivial workloads.

Hand-optimizing the TCC code generator
C4 comes to mind (C in 4 functions), https://github.com/rswier/c4.
have you considered adding a backend for LLVM? perhaps a bit heavyweight, but it could be a good way to get C/C++, fortran, rust, etc. if that's something you'd like!

Some people of the Linux Community in a nutshell
I use Alpine Linux (no GNU bloat btw), dwm (Sucks less!), and I edit all my C (no bloat language) through busybox ed and compile my programs with (c4)[https://github.com/rswier/c4]

which programming language was used to make c++ compiler?
Keep in mind you can create a "usable" C compiler by yourself, and is doable in surprisingly low amount of code. Try https://github.com/rswier/c4/blob/master/c4.c

What are some alternatives?
