Ruby 3.3.2 Released https://www.ruby-lang.org/en/news/2024/05/30/ruby-3-3-2-released/

Ruby 3.3’s YJIT: Faster While Using Less Memory https://railsatscale.com/2023-12-04-ruby-3-3-s-yjit-faster-while-using-less-memory/

It feels weird that websites ask you to solve a puzzle to check if you're a human. I'm pretty sure ChatGPT can solve all of it, and I often fail at those.

TIL the links of `https://github.com/foo/bar/issues/1234` and `* https://github.com/foo/bar/issues/1234` are rendered differently on GitHub. I've sometimes triggered the latter behavior and it's useful.

Ruby 3.3's YJIT Runs Shopify's Production Code 15% Faster https://railsatscale.com/2023-09-18-ruby-3-3-s-yjit-runs-shopify-s-production-code-15-faster/

@joeldrapper Did it speed up your specs as of 3.2? JIT is suitable for speeding up operations that are repeated many times like in production as you said. But tests often run each path a few times and that's it, so I normally don't expect a speedup there.
