We're thrilled to be back at @rubykaigi as a Ruby Sponsor & host of the Ruby Committers event last night! 🇯🇵 🎉

The Ruby & Rails Infrastructure team at @Shopify have lots to share, including a new JIT compiler, new Ruby LSP APIs for handling DSL, and performance optimizations.

Until then, check out what we're working on at railsatscale.com and shopify.engineering. #rubykaigi

As @hachiblog pointed out during the lighting talk, some gems are not (yet) compatible with the fiber scheduler, but this relatively small PR will fix the issue: github.com/grpc/grpc/pull…

Have you ever struggled with debugging memory leaks or OOM kills in Java or Go?

My team at @datadoghq has recently shipped a guided memory leak workflow that can quickly guide you through the right steps to find and fix the problematic code.

The fix for this has landed and will be in go1.24 as well as the next minor release for go1.23 🎉.

Thanks to the Go team for the fast review as usual 🙇🏻‍♂️
I just noticed that go tool trace slightly changed its behavior when it comes to the stack traces it displays in go1.23 compared to go1.22.
