distribution VS ruby

This is something that kind of annoys me; there's even a /r/rails sub-reddit specifically for Ruby on Rails stuff. Understandably Rails helped put Ruby on the map. Before Rails, Ruby was just another fringe language. Rails became massively popular, helped many startups quickly build their Web 2.0 sites, and become successful companies (ex: GitHub, LinkedIn, AirBnB, etc). Like others have said, "Rails is where the money is at". However, this posses a problem for the Ruby community: whenever Rails becomes less popular, so does Ruby. I wish the Ruby ecosystem wasn't so heavily centralized around Rails, and that we diversified our uses of Ruby a bit. There's of course Sinatra, dry-rb, Hanami, Dragon Ruby, SciRuby, and a dozen security tools written in Ruby such as Metasploit, BeFF, Arachni, and Ronin.

Welcome! Ruby isn't exactly "dying", but the hype/popularity is definitely fading. This is primarily because Ruby is no longer "new", most of Ruby's popularity came from Rails, and now Rails is no longer the "new hotness". However, Ruby still has lots of awesome features and lots of awesome other libraries and frameworks, such as the new fancy irb gem that uses reline, nokogiri, chunky_png, the async gems, Dragon Ruby, SciRuby, Ronin, and the new Hanami web framework.

Ruby is mainly used in web app development because that's what makes money. However, Ruby is also used in Information Security (infosec) and there are a dozen or so Ruby security tools and libraries (metasploit, ronin, arachni, dnscat2, dradis). There's also SciRuby which aims to allow Ruby being used in the scientific/academic fields. You've probably heard/seen DragonRuby which is helping to popularize Ruby for simple game development. There's also a lot of interesting work happening around mruby and mruby-c (see mruby/c on Flipper Zero and mruby on DreamCast).

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 testing with RSpec

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.

Link to the commit

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.

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.

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.

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.
