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.

🚀Secure Rails Authentication: A Step-by-Step Guide to Sign Up, Log In, and Log Out
To create a new Rails app, you should have Ruby and Rails installed on your machine. You can find how to install Ruby on your local machine using the Ruby docs. You can install Rails by running the following command:
- Ruby – Implement Chilled Strings
- Ruby 3.3

YJIT Is the Most Memory-Efficient Ruby JIT
Not parent poster and do not have production YJIT experience. =)
My guess is that you would monitor `RubyVM::YJIT.runtime_stats[:code_region_size]` and/or `RubyVM::YJIT.runtime_stats[:code_gc_count]` so that you can get a feel for a reasonable value for your application, as well as know whether or not the "code GC" is running frequently.

GitHub and Developer Ecosystem Control
Part of the major userbase pull in GitHub revolves around hosting a considerable number of popular projects including Angular, React, Kubernetes, cpython, Ruby, tensorflow, and well even the software that powers this site Forem.

Undocumented Features of GitHub
Hold option and click on the “collapse file” button in the Files view of a commit or pull request, and it will collapse all the files.
Select text in a comment, issue, or pull request description and press r—the selected text (including markdown formatting) will get pre-populated as a markdown block quote reply in the next comment box.
Add .patch or .diff to any pull request URL if you want to see a plain-text diff of the pull request (e.g. maybe you want to quickly `curl ... | git apply -` an unmerged pull request into a local copy of the repo without trying to add and fetch the git remote that the pull request is from).
There are lots of keyboard shortcuts. For example, / to jump to the file finder.
Not so much a secret but more like a hiding in plain sight: when looking at a commit GitHub will show you the earliest and latest tag (i.e. release) that includes the commit. For example, this commit[1] first appeared in v3_2_0_preview3.

Ruby Outperforms C: Breaking the Catch-22
The title is misleading, just like other commenters mentioned. Just check how much indirection "rb_iv_get()" has to make (at the end, it will call [1], which isn't "a light" call). Now, check generated JIT code (in a blog post) for the same action where JIT knows how to shave off unnecessary indirection.
We are comparing apples and oranges here.

How to Check If a Variable Is Defined with Ruby's Defined? Keyword
I'm not sure why, but all the source values are listed here: https://github.com/ruby/ruby/blob/1cc700907d3ad3368272488a6f...
Maybe someone knowledgeable in the underpinnings of Ruby will explain why "class variable" was not hyphenated.

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
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.

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.
