*Kaigi on Rails, not RubyKaigi. Shibuya. You should come!

ファイルをアップロードしてバックグラウンドで処理する実装をActiveJobに渡される時点でファイルは読み取り可能になっている前提の超楽観的な実装にしていたところ、Rails8系(8.1)ではレースコンディション（FileNotFoundError例外）になってしまい涙目で修正したら収ってリトライの検証ができない🥺

Just when you thought you couldn't possibly like Japan any more 🤩. Can't wait to come to RubyKaigi in October. Such a beautiful, wise country.

TIL: Solid Queue can replace Sidekiq for 90% of what I need in production. My Gleania background jobs: → AI feedback analysis: Solid Queue → Email notifications: Solid Queue → Webhook processing: Solid Queue One less dependency. One less bill. Rails 8 is underrated.

Change absolutely everything except what works. @intercom built https://fin.ai/ on Ruby on Rails and we’re surrounded by their ads and presence in SF.

Why does Rails 8 authentication come with User has_many :sessions? Because of PUSH NOTIFICATIONS. You want to register each session/device as a push destination.

Migrated a multi-tenant Rails app from Heroku to Kamal 2. The hardest part? SSL for hundreds of dynamic tenant domains. Caddy's on-demand TLS solved it. It validates domains against our Rails DB before issuing certs. No Cloudflare, no wildcard management. Here's the full setup 👇

[ENG] @igor_alexandrov at Tropical on Rails 2026! Co-founder and CTO of JetRockets, Docker Captain, and a Ruby/Rails engineer since 2008, Igor is also an active open-source contributor to projects like Kamal. He'll be presenting "Overreacting – from React to Hotwire." If you've ever wondered whether your app really needs a full JavaScript framework or if Hotwire can do the job, this is the talk for you. Igor will walk through the journey of moving from React to Hotwire and what that shift looks like in practice. 📅 April 9-10 · Pullman Vila Olímpia, São Paulo 🔗

Due to some personal things I have to take care of this weekend, there will not be a Short Ruby Newsletter sent on Monday. I may be able to send it on Tuesday, but we’ll see how the week looks. There’s already a big archive of previous editions at https://newsletter.shortruby.com/archive

@bcherny announced the next iteration of /simplify on Claude Code. I have built since the first announcement rails-simplifier https://maquina.app/documentation/ai-tools/rails-simplifier/ It works as an agent and helps to enforce 37signals' vanilla Rails philosophy, always refactors toward simplicity. Rails should be so expressive that one developer can build a competitive product. That only holds true when you write idiomatic Rails, not Rails buried under layers of custom abstractions.

There were 14 contributors to the framework this week. Thank you to those whose PRs were highlighted: @flavorjones Iliana Hadzhiatanasova (ilianah) @elalemanyo Find the full list here: https://contributors.rubyonrails.org/contributors/in-time-window/20260221-20260228

This Week in Rails is out, and in one of the most notable changes, Action Text now exports rich text as Markdown. `RichText`, `Content`, `Fragment`, and `Attachment` all get a `to_markdown` method, mirroring the existing `to_plain_text`. It handles inline formatting (bold, italic, strikethrough, code), headings, blockquotes, lists, tables, links, code blocks, and more. It also benchmarks ~35% faster than `to_plain_text` - a great option for anyone sending Rails rich text to LLMs or Markdown-based pipelines. Plus: `MissingAttachable` now renders consistently in plain text too, custom content types for HTTP auth challenges, and "open in editor" links fixed for devcontainers & Docker. Find all the PRs and highlights here:

Omarchy 3.4.1 is out with Hyprland 0.54 and its new niri-like scrolling layout. It's even configurable on a per-workspace basis, so you can stick with dwindle for your main spaces that you keep neat, then go messy on others. Enjoy! https://github.com/basecamp/omarchy/releases/tag/v3.4.1

My new favorite tmux dev layout features @opencode (with Kimi K2.5 running on @FireworksAI_HQ) on top and Claude Code on the bottom. I start almost all agent tasks with Kimi (so fast!), then ask Claude if I need a second opinion/more advanced stuff. Great combo!

Shopify is another company going all in on Minitest. They deprecate their rspec-queue runner. I haven't realized I'll see real shift from RSpec but it's happening in real time as we speak. Back to defaults that just work (tm).

Rust is now inside Ruby’s core. Not a rewrite. Not a replacement. A new systems layer powering YJIT — Ruby’s production JIT compiler. A quiet but important shift for performance and safety in MRI. 🔗 Read more: https://rubystacknews.com/2026/02/27/%f0%9f%a6%80-rust-inside-ruby-core-a-new-systems-layer-for-mri/ #ruby #rustlang #YJIT #programming

Consistency in the bigger one. The main application was written with minitest (test-unit) even before rspec was created, so to avoid splitting investment in build tooling for two frameworks we had to chose one, and the one with more tests written was minitest.

Rspec isn’t not only deprecated, it is forbidden. Projects using it in the past aren’t asked to rewrite the tests, but new projects can’t use. And with AI, there is a possibility we will rewrite
