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.

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.

Using Thread.new
You may want to consider using something like concurrent-ruby that provides nice abstractions over multithreading.

Saving an image modified by vips using activestorage?
I'm trying to add a watermark to images as they are uploaded before they're saved. I'm using the following code(borrowed heavily from the example here)

ruby-vips VS rszr - a user suggested alternative

I made a thing with Ruby; looking for feedback! Xferase is a photo library management daemon for Linux.
Photein uses Minimagick for image management and conversion. Have you had a look at ruby-vips? From what I hear it should be better/faster/use less memory than ImageMagick, especially for the standard image formats.

Best of (Ruby) Gems Series - What's Next? What's Hot?
A special mention to ruby-vips, which is (along with maybe php, I guess) one of the few language bindings maintained by the author of libvips, which should become the defacto image processing manipulation library.
What are some alternatives?
