Alongside the Ruby 4.0 release last week, I published charm-ruby over Christmas, bringing @charm.land's excellent terminal UI libraries to Ruby. A full TUI framework, reusable components, styled output, forms, markdown rendering, spinners, charts, and a lot more! Demos below ⬇️

Can threads and fibers be friends? That's what I set out to find out this week: noteflakes.com/articles/202...

I became a software engineer because writing code is fun. Thinking through hard problems, designing elegant solutions, seeing the things you’ve built working for the first time… these moments are all deeply satisfying, so why in the world would I ever surrender them to AI?

I'm really happy to see @marcoroth.dev receive the 2025 Rails Luminary Award! 🎉 He’s done so much for the Rails ecosystem and the Ruby community. Huge congrats, Marco! 🙌 And it's great to have @fxn.bsky.social and @amandabrooke.bsky.social around. #rails #RubyOnRails #ReActionView #herb

My OSS report for this week: fibers are the future of Ruby! noteflakes.com/articles/202... #ruby #uringmachine

More work on UringMachine benchmarks. This validates the work of @ioquatix.bsky.social on the fiber scheduler. We see a marked performance advantage to using Ruby fibers for any I/O-bound workload, including querying PostgreSQL databases. github.com/digital-fabr...

Just pushed some preliminary benchmarks measuring the performance of UringMachine against stock Ruby I/O, and the results are promising! github.com/digital-fabr...

My OSS report for this week: the fiber scheduler is feature complete, more tests to come, and some new thoughts about Papercraft. noteflakes.com/articles/202... #ruby #uringmachine #io_uring #papercraft

Do we really need CSS "frameworks"? I don't think so. Modern CSS is awesome! www.zolkos.com/2025/12/03/v...

How cool would it be if we had something like Elixir's macros in Ruby? Let's find out: github.com/digital-fabr... This could be a revolution in code generation for Ruby! I'm targeting Papercraft with this, but @joel.drapper.me's Phlex and @marcoroth.dev's HERB might benefit as well...

Happy to announce that Gem Fellowship applications are now open! If you're a Ruby open source maintainer, this grant program is for you. 💎 https://gem.coop/fellowship/

Here's my OSS report for this week: the UringMachine fiber scheduler is taking shape, another Ruby core PR, and some learnings about how Ruby does I/O. noteflakes.com/articles/202... #ruby

Here's a great insight by @joel.drapper.me about Phlex: > It’s not that Phlex provides abstractions itself — it mostly doesn’t... But it provides a mechanism for *you* to write abstractions. skywriter.blue/pages/did:pl... #ruby #phlex

My first post about the grant work I'm doing for the Ruby Association on UringMachine - a low-level API for using io_uring in Ruby: noteflakes.com/articles/202... #ruby

Announcing the Gem Fellowship, a grant program for improvements to Ruby-related open source projects. gem.coop/fellowship/ Want to improve your favorite gem? Submit a proposal, starting next month.

Here are the slides from my @sfruby.com keynote today! #sfruby #sfruby2025 speakerdeck.com/marcoroth/he...

More cool Ruby gems, this time related to databases and Active Record! First, alternatives to Active Record 😉 github.com/jeremyevans/... – from the creator of Roda; why not try out both together? github.com/rom-rb/rom – from the creators of Hanami; again, it's worth exploring both

Hanami 2.3 is out! This is a fantastic release, with improvements all across the stack, but the thing I’m most proud of is the whopping THIRTY TWO Rubyists who’ve chosen to contribute and make Hanami better. Thank you everyone! 🥰

Herb v0.8 is here! 🚀 The biggest release yet, packed with new language bindings, Linter Autofix support, Linter Fix-on-Save, a new `.herb.yml` config file, formatter improvements, Tailwind Class Sorting integration, and a ton of performance, tooling and LSP improvements! 🌿

The @euruko.org 2025 talks recordings are now available on @rubyevents.org! 🥳

Here's what I've been up to these last few weeks: noteflakes.com/articles/202...

This was such a good essay, I hope every member of the Rails core team will read it. okayfail.com/2025/in-prai...

I was recently reminded that not everyone fully understand what the frozen string literal magic comment is about. So I figured it was the occasion for another deep dive. byroot.github.io/ruby/perform...

the former maintainers of Bundler and RubyGems have a proposal: we want to move Ruby forward andre.arko.net/2025/10/26/w...

After a year hiatus, my series on all things Ruby concurrency is back! This post digs into the interrupt mechanism in Ruby threads. These interrupts revolve around bit masks, so it's got some Ruby bit work as well! Expect more regular updates from now on 💃💃💃 jpcamara.com/2025/10/22/b...

Ruby 4.0 is coming this Christmas!

rubyassociation.doorkeeper.jp/events/190436 12/20 にRuby リリース30周年イベントをやるのでみなさん来てください

I wrote about the designing the perfect type signature syntax in Ruby.

I've just released Papercraft 3.0: a new rendering API, improved support for XML templates and more. noteflakes.com/articles/202... #ruby #papercraft

Papercraft in IRB, some bug fixes, and more speed! noteflakes.com/articles/202... #ruby #papercraft

What if gem hosts had NPM-like scopes & your Gemfile could be: source "https://gem.example" gem "@duckinator/jim" OR: gem "https://gem.example/duckinator/jim" ... what if a PoC patch was 25 lines, and a 1-line kludge meant you can test it against a production server? github.com/gem-coop/gem...

I just released Papercraft version 2.19: You can now use Papercraft in IRB! #ruby #papercraft

The Ruby community moves fast!

I've just released roda-papercraft, a Papercraft plugin for Roda. More goodness for alternative Ruby web frameworks! github.com/digital-fabr... #ruby #roda #papercraft

announcing a new community-focused gem server from the team previously behind rubygems: gem.coop. join us and start using it today!

While at it, I also added built-in HTML templating via @noteflakes.bsky.social 's beautifully simple Papercraft library papercraft.noteflakes.com

Just finished my weekend project: making Papercraft templates work in Hanami apps. Here's the story: noteflakes.com/articles/202... #ruby #hanami #papercraft

The Papercraft website is up: papercraft.noteflakes.com Papercraft is a little Ruby gem for generating HTML using plain Ruby.

Papercraft 2.16 has just been released. This version adds support for rendering namespaced components. github.com/digital-fabric/papercraft I'm also busy preparing Papercraft docs site. Hopefully it'll be ready in a couple of days.

I just release Papercraft 2.15. Papercraft is a Ruby gem for writing functional HTML templates in pure Ruby. Check it out: github.com/digital-fabr... #ruby #papercraft

My thoughts on Euruko: noteflakes.com/articles/202... #ruby #euruko

Friendly.rb is taking a break. We've had quite a few questions about that and wanted to share them publicly. blog.adrianthedev.com/friendly-is...

Netanyahu: ‘These So-Called Genocide Experts Have Probably Never Committed A Genocide In Their Lives’

Today I've wrapped up my work on P2 - now merged into my beloved Papercraft. Now it's time to advance on my new web framework (which I already use on my website). noteflakes.com/articles/202...

@push.cx P2 is now merged back into Papercraft. It started as an exploration of how to make Ruby DSLs faster, but I've been learning so much in the last few months. P2 not only matches the performance of ERB, it also allows for more advanced features.

Great talk from @timriley.info about promoting diversity in the Ruby ecosystem. Thanks Tim! www.youtube.com/watch?v=6jUE...
