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.

Must-have gems for mature Rails

My First Code Commit in Ruby
My talk is about different best practices - specifically when adhering to them breaks down. One of those best practices is high test coverage. I start to work on the content for my presentation by building the code samples that I want to use in the slides. For the code coverage section, I'm writing some code with some tests. I'm using SimpleCov to generate code coverage results.

Improve Code in Your Ruby Application with RubyCritic
SimpleCov - a tool to check Ruby application code coverage. You can configure it to run alongside your tests. It provides metrics on code coverage so that you can identify what you need to pay attention to and where to invest your time to create better test cases.
-
Paying Down Technical Debt
Ensure that you have sufficient test coverage. You can use code coverage analysis tools like SimpleCov to gain insight into gaps in your coverage.

How to test all workers in one big loop?
simplecov might the answer you need, it generates a report of the lines of code your test suite hits.
-
How to Improve Code Quality on a Ruby on Rails Application
Use SimpleCov to generate a report of how many statements are covered by your test suite. It won't assess the test suite quality, though.

Ruby's Got You Covered
There are many tools for measuring test coverage, but one is SimpleCov. It also supports branches coverage. To measure coverage of production code, check out Coverband, which you can set up to use oneshot lines mode.

Question about wrapping instance vars in attr_reader
Technically you could measure the usage with MethodCoverage. But that is future talk for simplecov. So in theory we could visualize unused instance variables

YJIT Is the Most Memory-Efficient Ruby JIT
https://github.com/ruby/ruby/blob/master/doc/yjit/yjit.md#co...
It just dumps all the JIT-compiled code? I'd expect to see some kind of heuristic or algorithm there... LFU or something.
The internals of a JIT are essentially black magic to me, and I know the people working on YJIT are super talented, so I am sure there is a good reason why they just dump everything instead of the least-frequently used stuff. Maybe the overhead of trying frecency outweighs the gains, maybe they just haven't implemented it yet, or maybe it's just a rarely-reached condition.
Also for a practical tip on YJIT memory usage, note that there is a "--yjit-exec-mem-size" option, see https://github.com/ruby/ruby/blob/master/doc/yjit/yjit.md#co... for more details. (This command-line argument is mentioned in the paper https://dl.acm.org/doi/10.1145/3617651.3622982 but not in this blog post about the paper.)
At Heii On-Call https://heiioncall.com/ we use:
ENV RUBY_YJIT_ENABLE=1
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.

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.

A Tour of CPython Compilation
As with actual spoken languages, programming languages have their own grammar as well. I've you've read any RFCs for networking protocols you may have come across a variation of Backus–Naur form, commonly referred to as BNF. The HTTP protocol uses an augmented version of it for its standard. Other languages such as Ruby may even utilize a grammar file.

Everything about this Device is so good but I need to know if there is an easy way to delete duplicated games like almost 10K + is duplicated
It relies on ruby and would be installed with ruby gems: gem install finddups TBH, I've only tested it with macOS. It should work with linux too, but I don't think it will work with windows.
