ruby + rails + hotwire native + xcode + claude code = heaven !!!

I say a lot that fixtures are faster, but I actually use them because I like them more. I would also use them if they are slower...

Built this for our use case at work. Server software/config changes in a simple Ruby DSL in your app, like rails migrations. Pairs really well with Kamal. @dhh do 37Signals do anything like this? Or use one of the big boys (Chef, Ansible, etc) https://github.com/foundercatalyst/simple_infrastructure

Thanks to the Ruby Board for publishing an update today. https://rubycentral.org/news/a-message-from-the-ruby-central-board It does leave some questions though, which I appreciate is difficult in a public forum.

If you've already received a Panther Lake machine, you can run the dev build of Omarchy 3.5 to have everything work out of the box. It might still have some sharp edges, but it's way better than not running Linux on your Intel champion machine 😄 https://iso.omarchy.org/omarchy-3.5.0-dev.iso

While everyone was complaining about Claude yesterday or whatever day that was I put the finishing touches on…. The Wild Ecosystem 10 Ruby gems. One mission: make AI agents safe in production Rails. The wild ecosystem is a family of focused, open-source Ruby gems that together form a governed operational intelligence layer for AI-assisted development workflows. Every gem enforces safety by default - read-only where it matters, audited everywhere, bounded always. Built collaboratively with @claudeai

🚀 A complete guide to deploying a Rails 8 app with Kamal on a single server. Covers container setup, deployment flow, and how jobs, caching, and WebSockets run via the Solid stack. #Rails https://mooktakim.com/blog/deploying-rails-with-kamal/

I released rbtree3 for Ruby with support for Ruby 4.1. Thanks to @hsbt for the patch. https://rubygems.org/gems/rbtree3

New version of ruby-build is available at this time. https://github.com/rbenv/ruby-build/releases/tag/v20260327

Ruby 3.2.11 has been released https://www.ruby-lang.org/en/news/2026/03/27/ruby-3-2-11-released/ This release is the final version of the 3.2 series. From Christmas 2022 to today, three years of contributions made Ruby better. Thank you all.

I wrote the end-to-end guide I wish existed when I first deployed Rails 8 with Kamal. Every step from ordering a Hetzner server to production. Ansible, Kamal, Solid stack, Cloudflare, Litestream backups, and monitoring. No Postgres. No Redis. No PaaS. https://mooktakim.com/blog/deploying-rails-with-kamal/

Rails 8.0.5 ve 8.1.3 sürümleri duyuruldu https://www.getgnu.org/programlama/rails-8-0-5-ve-8-1-3-surumleri-duyuruldu.html

Concerto 3.0.0-rc1 is officially here! 🎉 18 years after our first screen went live at @rpi, we’ve rebuilt Concerto from the ground up for the modern web. - Pinned Content 📌 - OIDC/SSO 🔐 - Rails 8 & Vue 3 ⚡️ Read more and try the demo: https://www.concerto-signage.org/blog/2026/03/24/concerto-3-rc1

Shipped PagerDuty-style alert escalation today for my $39/mo SaaS. 21 commits. Emergency call comes in, AI captures it, contractor gets an SMS. No response in 10 minutes? Auto-calls them. Still nothing? Escalates to backup. Daily summary at end of day. Built it in Rails 8 with Solid Queue + Twilio. No third-party escalation service, no extra cost. Just background jobs that check if someone acknowledged the alert. The whole point of GetBackTo is follow-through, not deflection. Every competitor answers the call and moves on. We make sure the contractor actually does something about it. https://t.co/k6WBzUZClv #buildinpublic #rails #saas #indiehacker

🔄 Devise can be overkill for simple apps. A step-by-step migration to Rails 8’s built-in authentication, covering schema changes, helpers, and tests. #Rails https://nithinbekal.com/posts/devise-to-rails-auth/

Action Policy is the best authorization thingy for Rails I am kind of surprised not everyone is on it yet Now with refreshed docs

If you know someone from Anthropic, this is a good time to whisper to them to add Ruby LSP to their official plugins: https://github.com/anthropics/claude-plugins-official/pull/106

How do we feel about Inlay Hints in HTML+ERB files for closing tags? I'm torn, but the good thing is that most editors allow to disable Inlay Hints if you don't like them. Is this something people would want to use Inlay Hints for? I'd love to hear your opinion!

JRuby currently has no official ActiveRecord support for Rails 8, but one of our users discovered that a build from master works right now! It will need some cleaning up, but we'll be caught up with Rails compatibility very soon. Rails 8 plus JRuby 10.1 will be a game changer.

Reminder: Ruby 3.2 is end of life in just a few weeks. You should consider moving to Ruby 4 now (or minimally 3.4)

Looks like we've found the first mention of RubyLLM in a book! Thanks @taq! ---

Ruby on Rails: Compress the complexity of modern web apps ➜ This Week in Rails: March 6, 2026 https://rubyonrails.org/2026/3/6/this-week-in-rails

Exactly as you would with a human: automated testing. Unit tests, functional tests, the rest. If you let agents produce a mountain of slop without any testing, you'll get the same buggy crap as when humans try to do that.

Opus produced the best output with Ruby in this shoot-out between a bunch of different languages. Fewest tokens, fewest LOCs, fastest completion. Maybe one day, AI will just be writing straight machine code, but until then, Ruby is a superb target. https://dev.to/mame/which-programming-language-is-best-for-claude-code-508a

🧱 TutorialKit.rb packages Ruby, gems, and application code into WebAssembly modules so a Rails app, database, terminal, and server run locally in the browser. #Rails https://evilmartians.com/chronicles/tutorialkit-rb-the-ruby-wasm-journey-goes-onward

If you use @supermemory to index your codebase, and you use .NET, Java, Ruby PHP, Rust, Python, Go, Swift, or Elixir, you now get a significantly better experience. It’s all thanks to much more in-depth prompts that guide the process for more ecosystems. Update your plugins and check it out!

My first PR to Rails got merged! 🥳 It's a small documentation fix. https://github.com/rails/rails/pull/56927

Ruby on Rails scales from PROMPT to IPO. Token-efficient code that's easy for agents to write, and still beautiful for humans to review. https://rubyonrails.org/

💎 The Mailtrap Ruby SDK just got a major upgrade. It now supports the full Mailtrap feature set, including batch sending, sandbox testing, contact management, templates, and more. See the full docs and GitHub repository here: https://docs.mailtrap.io/guides/sdk/ruby

Hello friends! This is our first edition of the Ruby Events Newsletter! Find recent events, released videos, and a changelog within. Let us know if there's anything you want to see in March's edition? 🤩 https://www.rubyevents.org/announcements/february-2026-newsletter

The `textDocument/documentHighlight` request in the Language Server Protocol is kinda neat! The Herb Language Server will use it to highlight matching ERB control flow keywords and HTML tag pairs when you place your cursor on them.

Kamal + Docker -> Deploy multiple applications on a single VM. (Python FastAPI) + (Rails + Postgresql) + (Wordpress + Mysql) All on local VM with SSL + HTTPs Try here: https://github.com/Ansarissab/kamal-multi-app-deployment-examples

Providers keep shipping terms that explain nothing. "System prompt"? That's just `instructions`. "Parallel tool calling" for "how many tool calls in a response"? That's `calls (:one / :many)`. Clear names make better software. https://rubyllm.com/tools/#parallel-tool-calling-calls

RubyLLM 1.13 is out, and it’s packed. More control. More stability. Less memory usage. Some examples: - safer tool calls: invalid args + non-existent tools handled gracefully - explicit tool control with `choice` + `calls` - structured output now works with Anthropic + Bedrock - retries that actually work (POST, context-length, 504 handling) - better provider flexibility + Rails/agent lifecycle fixes and a million other things improved by 27 contributors! https://t.co/m5ek3gk8m1

Just published Part 5 of my Riding Rails series! 🚂 We built a details view for job listings and wrapped up the tutorial. One key lesson: resource-based routing in Rails saves you from writing seven separate routes. Have you used Rails resources yet? Link in reply.

Double dose of RubyLLM at Ruby Community Conference 2026. I'll both run a workshop and deliver the closing keynote. Hope to see you there!
