Kino, the ractor server, 0.6.0, is out with native HTTP/2! Surprising benchmark results: +79% over HTTP/1.1 on the same server, 2× over TLS, +50% vs nginx-terminated h2.

Just updated bundlebun (a gem including a fast JavaScript runtime, package manager, and builder for Ruby and Rails applications) to Bun 1.4.0, the Claude-Rust-rewrite! github.com/yaroslav/bun... If you are afraid to test it out, just make sure to freeze bundlebun to 0.5.0.1.3.14.

Rubyists who experiment with Ractors, put them to work! Meet Kino, an experimental performant Ractor web server (with a threading fallback). github.com/yaroslav/kino Note that Ractors are experimental, and so is this server. Rails cannot run on Ractors yet, but it will, sometime in the future. 🧵

Attention bundlebun users. We have version pinning for a reason. The latest version of Bun might also be the last truly stable version of Bun in the nearest future. Pin it like this: # Gemfile gem "bundlebun", "= 0.5.0.1.3.14" To freeze the Bun version.

Carbon Fiber is a high performance Ruby Fiber Scheduler powered by Zig and libxev (same as used in Ghostty). I've just released a new version: updated to Zig 0.16, latest libxev. Some optimizations, too—it's now faster! (benchmarks in README) github.com/yaroslav/car...

Astro @astro.build users, were you ever annoyed by how it names your packed assets? Now there is an integration for that: github.com/yaroslav/ast... MyComponent.astro_astro_type_script_index_0_lang.HASH.js becomes my_component.HASH.js...

The fonts used on yaroslav.io are Unifora by @yeptype.bsky.social (main font) and Berkeley Mono "TX-02" (mono) by U.S. Graphics Company. They make a great pair, WDYT? Both available as variable fonts. Unifora pricing is a steal.

Introducing Bundlebun: a gem that packs @bun.sh by @jarredsumner.com—runtime, package manager, build tool—right into your Gemfile, with version pinned. Plus: Rails' history with asset pipelines and JS, and why #nobuild doesn't work most of the time. yaroslav.io/posts/bundlebun-bundles-bun

So I've finally got a blog of my own! I'll be sure to post the articles here as well—or you can subscribe to a feed. yaroslav.io/posts In the near future, I'll mostly write about open source projects I've done lately and continue doing. Staying away from "thought leadership" BS.
