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.

What are the downsides of Ruby ?
In that situation, if there was a performance critical component we wanted to optimize by rewriting in Crystal, we would first extract it into its own app or worker (aka breakup the monolith, aka micro-services). Additional apps could have requests routed to them via a reverse proxy or they could be internal HTTP-endpoints. Then we would port that code to Crystal, replacing gem dependencies with Crystal shards equivalents (which there are many, and more are being added everyday), and then running the Ruby code through rubycodemod_crystal which changes minor things (ex: include? -> includes? or require 'foo' -> require "foo"). Assuming this component has RSpec tests, I would convert them to Spectator which is a Crystal clone of RSpec. Then I would tighten up the Crystal code by adding explicit Types to all instance variables and method signatures, so the compiler doesn't have to infer the types. This is basically the same process I have done when porting some of my own Ruby libraries to Crystal.

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).
