Ruby 3.3.0 Preview 3 Released — With just 39 days till Christmas and Ruby 3.3, it’s time for another preview release. 3.3.0-preview3 retains all the prior 3.3 improvements like those to YJIT performance, but also introduces the M:N thread scheduler and the Prism Ruby parser (formerly YARP).

YJIT is the Most Memory-Efficient Ruby JIT — Shopify’s tireless work on YJIT has paid off in many ways, including a ~15% speed-up for their storefronts. The team’s methodology on benchmarks, however, goes beyond performance to warm-up time and memory (RSS) size. All in all, YJIT is shaping up to be what we hoped it would be: a great boost to Ruby and Rails development.

Today we're introducing the official Rails Job Board, a platform for Rails developers to find their next role (and companies to find their next Rails developer). Get started and find your next career match here:

Ruby 3.3.0 Release Candidate 1 Released — We’re now just 11 days from the final release, but Shopify is already using this in production. There are few changes since preview 3, though I note ‘code GC’ is now disabled by default, but this seems like a good thing for performance in most cases.

Enqueue Multiple Jobs Together with perform_all_later in Rails

Are you still looping over the list of jobs to enqueue them individually? This post explores the new perform_all_later method in Rails, which was introduced in Rails 7.1 and lets you enqueue multiple jobs together to reduce the round-trip to the job backend, like Redis or the database.

Digging into Turbo 8's Morphing Feature in Ruby on Rails

The gist of the blog post and talk is that Turbo frames and streams are useful but often cumbersome to integrate since they are highly focused containers of logic.

They won’t be going away but might be more of a _special-use_ tool coming up with the introduction of morphing which could be a more convenient and useful “default” much like the standard full-page reloads of historical Rails apps.

Just like image_tag, audio_tag and video_tag can now accept Active Storage attachments. From Rails 7.1 they can generate audio and video tags when passed an attachment without the need to call polymorphic_path.

Here's what's coming in Rails 8
