This post describes the new modular garbage collection feature in Ruby 3.4: The ability to override Ruby's GC at runtime. We also introduce our first concrete alternative GC implem…

That's not correct: $ podman run -it -e RUBYOPT="--yjit" ruby:3.2 irb(main):001:0> puts RUBY_DESCRIPTION ruby 3.2.0 (2022-12-25 revision a528908271) +YJIT [aarch64-linux] => nil

You can see this chart and all the numbers and more at https://speed.yjit.org/ , which this chart was taken from.

10% less time for the same amount of work, since we are measuring the total response time of the workload in question and looking at median (p50), p90 and p99 numbers.

As far as I know, yes, it should. But I haven't tested it so I can't say for sure.

It is not a dumb question at all. At Shopify we use chruby since it is lightweight and less opinionated. However, devs never really have to use chruby directly, since our in-house …

We'd already deployed a prerelease version and started serving all Shopify storefront requests with Ruby 3.2 earlier this week. Here is a Twitter thread from me about all the work …

You do realize that market cap is not real money, right? That's like saying that an average American who earns 30K USD/year over 33 years will earn 1M USD and thus they should be c…

This is a great first step to making dependencies more secure in the Ruby ecosystem. Congrats to the whole team for getting this done!

I am afraid that is a shared concern for what Tapioca is doing as well. There are ways of mitigating that concern, by, for example, lifting all static methods on a model to be meth…

We have a lot of automation and infrastructure in place to give us that confidence. We have an extensive test suite of hundreds of thousands of tests, linting and static checks tha…

For the runtime, there is not much dark magic. Each type that has an `extend T::Sig` has `method_added` hooks registered, which notifies Sorbet runtime whenever a method is defined…

This is a great way to use Sorbet and get its benefits without having to invest 100% into typing. Great example, thanks for sharing.

Ultimately, the goal is for Tapioca to replace all `srb rbi` tooling and `sorbet-rails`. Right now, we exclusively use Tapioca for gem RBIs and we don't use any `srb rbi` tooling a…

Currently, no. On the contrary, since Sorbet syntax is pure Ruby, it needs a runtime component, so there is actually a small negative impact in performance at runtime. The reason w…

There was definitely some general suspicion when we first introduced Sorbet. However, there were also some early adopters who didn't mind the syntax but really wanted the benefits.…

Like others have stated in the thread, Crystal is a different language that shares some its syntax with Ruby. Our aim is to keep our Ruby codebase but adopt static types gradually.…

Happy to answer any questions here about our process, results or tools!
