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.

Happy Crystal user and code contributor here. (Also created https://github.com/compumike/crystal-docker-quickstart in case you want to try Crystal without installing anything.) In my opinion:
- Slow compile times are still a pain for iteration.
- The REPL / interpreter mode is still rough around the edges.
As far as companies using Crystal:
- We’re using it happily in production at Heii On-Call https://heiioncall.com/status
- Kagi is using it for their search engine backend https://news.ycombinator.com/item?id=32687071
- Other companies using it list: https://crystal-lang.org/used_in_prod/

Crystal for Rubyists
This is great Serdar.
As an alternative to Chapter 2 I’ll also share https://github.com/compumike/crystal-docker-quickstart my project template which lets you get a Crystal (currently 1.6.2) dev environment running with just Docker. Good for kicking the tires, which is what I think your audience is probably wanting to do! And then eventually can install a binary package as you suggest.

Marten, a Crystal web framework that makes building web apps productive and fun
My side project https://totalrealreturns.com/ is now about 5k lines of Crystal. There are some rough edges: in particular I think it could use a better templating solution (a port of HAML would be ideal!), and there are some failure modes with the Redis connection pool that have required workarounds.
This includes unit tests: the built-in spec framework is great and much like rspec. https://crystal-lang.org/reference/1.6/guides/testing.html
I'm now starting to use Crystal for internal backend infrastructure and microservices.
For anyone who wants to kick the tires on Crystal, I built a crystal-docker-quickstart project template: https://github.com/compumike/crystal-docker-quickstart works without having to install anything locally. (Assuming you have docker.) You can have your own, home-built "Hello world" static binary in under a minute:
git clone https://github.com/compumike/crystal-docker-quickstart.git my_app && cd my_app && ./d_dev

Crystal Programming Language
If you'd like to try out Crystal without installing anything locally, I've created a tiny Docker container with a Crystal project template:
https://github.com/compumike/crystal-docker-quickstart
For example, you may do:
git clone https://github.com/compumike/crystal-docker-quickstart.git my_app

Ruby 3.3's YJIT: Faster While Using Less Memory
Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago.
If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly ruby-like in syntax, style, and developer ergonomics.[^2] Although it's an entirely different language. Also a tiny community.

What languages are useful for contribution to the GNOME project.
Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well.

Jets: The Ruby Serverless Framework
Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything.
My modern programming toolkit is basically golang + ruby + bash and I am never left wanting.
I do find Crystal (https://crystal-lang.org/) really interesting and am hoping it has its own "ruby on rails" moment that helps the language reach a tipping point in popularity. All the beauty of ruby with all of the speed of Go (and then some, it often compares favorably to languages like rust in benchmarks).
What are some alternatives?
bridge-cli - CLI for Crunchy Bridge
zig - General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.
sorbet-rails - A set of tools to make the Sorbet typechecker work with Ruby on Rails seamlessly.
Nim - Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).
