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.

Support for non-blocking fibers by wjordan · Pull Request #2601 · puma/puma
Tipi is from https://github.com/digital-fabric/polyphony and also in the PR they add a gem: https://github.com/digital-fabric/libev_scheduler
- Some thoughts on the Ruby fiber scheduler interface
-
What is the current state of event driven programming with fibers in ruby?
Lastly, if anything that I wrote here is wrong or inaccurate please correct me, but please don't take it personally! As I wrote in the libev_scheduler README, at worst I'm just some random guy being wrong on the internet. :-)

Exploring concurrent rate limiters, mutexes, semaphores
After this, I took a look at the semaphore class in the popular library, concurrent-ruby to see how they implement it, and I learnt about something new: condition variables. And Ruby comes with this included!

My Adventure with Async Ruby
https://github.com/ruby-concurrency/concurrent-ruby has great docs if someone is looking for alternatives.

My Adventure With Async Ruby
I wonder how this would compare to using concurrent-ruby under ruby 2.7, especially in a real-world setting (where the calls are actually to external services that return and buffer data, instead of just sleep). The author says that he's felt that ruby threads "feel easy to mess up," but I've found that concurrent-ruby makes it pretty simple, and performant enough even with the GIL.

Using Concurrent::Promise while rescuing exceptions in Ruby
As I could not find a clear example about how to rescue exceptions from Concurrent::Promises (part of the Concurrent Ruby gem ) I read through the documentation and here are two examples: one that documents success case and one that shows what is happening when there is an error.

Ask HN: Any efforts to remove the GIL for Ruby?
In a sense the GIL (or actually GVL as it's called in current ruby versions) has already been removed for ruby.
It's only the original MRI Ruby that still has it several over Ruby implementations already removed it. e.g. JRuby.
Concurrent-Ruby[1] is probably a good place to start if you want to work with GVL free ruby on JRuby. It's quite well supported and is currently used by Rails.
If you just want async or non-blocking IO I'd take a look at the Async Gem[2]. It looks pretty solid in Ruby > 3.0 and it's been invited by Matz to be part of the stdlib, which I think is a pretty good endorsement.
For MRI itself I don't think it's likely they'll ever remove the GVL. Ractors are probably a better solution for CPU concurrency in the long run, although I think they're pretty experimental currently.

Intro to Thread-safety in Ruby on Rails
I like how the article exposes you to tools to prove/disprove the problem. I would have hoped it introduced to tools like concurrent ruby and the use of atomics like u/Freeky already mentioned though.

How to get results from Concurrent::Promise::all?
Using conccurrent-ruby, how can I execute a set of promises and then get the results?

Ruby 3.1.0 Released
I’d highly recommend the concurrent-ruby gem that has implementations of various metaphors of concurrency, from async to promises, as well as edge features such as actors.
