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.

Sorbet Compiler: An experimental, ahead-of-time compiler for Ruby
(disclaimer: I work on the Sorbet team)
I think I understand GP's motivation: RBI files and RBS files are two different formats, and as a user of the language, people tend to want to use the officially blessed solution the language provides.
In case you weren't aware, parlour[1] is a popular open source project for working with RBI files. I believe it supports transparently converting between RBI files (Sorbet) and RBS files (Ruby 3).
There is also rbs_parser[2], a C++ parser for RBS files to convert them to RBI files, written by Shopify, a major user of Sorbet.
Stepping back: I haven't personally read many complaints from Sorbet users describing how the current state of RBI/RBS interop gets in the way of what they can actually do with Sorbet. Almost all the feature requests we get about Sorbet (both inside Stripe and outside) are for fixing bugs or implementing new language-level features. RBI files as implemented seem to work.
Sorbet already has an extensive set of RBI files covering the Ruby standard library (at least as good or better to my knowledge than any existing repository of types for RBS files), and there are plentiful tools for working with RBI files, listed here.[3]
If lack of first-party RBS support in Sorbet is holding you back from trying Sorbet, I'd strongly encourage you to give Sorbet a try anyways! Many people have shared great experiences adopting Sorbet in their Ruby codebases.

Should You Be Scared of Unix Signals?
When using green threads/fibers/coroutines, an interesting technique to make signal handling safer is to run the signal handler asynchronously on a separate fiber/green thread. That way most of the problems of dealing with signals go away, and there's basically no limitation on what you can do inside the signal handler.
I've successfully used this technique in Polyphony [1], a fiber-based Ruby gem for writing concurrent programs. When a signal occurs, Polyphony creates a special-purpose fiber that runs the signal handling code. The fiber is put at the head of the run queue, and is resumed once the currently executed fiber yields control.

- Polyphony: Fine-Grained Concurrency for Ruby
-
Polyphony 0.99 released. Last release before 1.0!
Polyphony is a gem for building highly-concurrent Ruby programs. It utilizes Ruby fibers to provide a high-performance safe environment for launching any number of concurrent operations. Under the hood, Polyphony employs io_uring to maximize I/O performance (libev is used on platforms other than recent Linux kernels).

About that monkey-patching business...
Is monkey-patching inherently bad? Should its use make Polyphony illegitimate? These are the questions I'm exploring in my latest article.

Embracing Infinite Loops with Ruby and Polyphony
Infinite loops are great for expressing long-running concurrent operations. In this article I’ll discuss the use of infinite loops as a major construct when writing concurrent apps in Ruby using Polyphony. I’ll show how infinite loops differ from normal, finite ones; how they can be used to express long-running tasks in a concurrent environment; and how they can be stopped. Read it now!

What's new in Polyphony and Tipi - August 2021 edition
Polyphony is a library for writing highly concurrent Ruby apps. Polyphony harnesses Ruby fibers and a powerful io_uring-based I/O runtime to provide a solid foundation for building high-performance concurrent Ruby apps.

Sorbet Compiler: An experimental, ahead-of-time compiler for Ruby
> Curious if there’s anything public about improving ruby performance from the I/O angle mentioned in the post.
I'm currently working on Polyphony [0], a Ruby gem for writing highly-concurrent Ruby apps. It uses Ruby fibers under the hood, and does I/O using io_uring (on Linux, there is also a libev-based backend).
