Happy Wednesday! Here is issue #153 of our newsletter, bringing you news and the best tools for your current or future Rails projects… 1. 🚀 Conferences are often where the Ruby community’s best ideas and conversations come together. In this recap, Kevin Murphy reflects on Blue Ridge Ruby 2026, sharing highlights from the talks, people, and themes that stood out throughout the event. It’s a nice snapshot of where the Ruby ecosystem and community conversations are heading this year. 📺 Speaking of, Ernesto’s Lightning Talk: Teaching Claude Code to Upgrade Rails is live. Check out the other presenters here: Blue Ridge Ruby 2026 Videos 2. 📚 Rails configuration can become increasingly difficult to reason about as applications evolve over time. In this post, Ben Sheldon reflects on a year of working with Ruby on Rails configuration patterns and the lessons learned along the way. Whether you're intrigued by monkeypatches or Turbo Streams, explore these Rails revelations with us! 3. 🛒 Managing inventory at a massive scale requires more than simple database transactions. Emilie Noel at Shopify breaks down how they scaled inventory reservations across distributed systems (surviving Black Friday) without a single oversell. Dig into their use of MySQL 8's SKIP LOCKED feature and the surprising bottleneck they uncovered along the way. 4. 🗑️ The Art of Deleting Code. Discover why trimming your codebase is the ultimate solo dev superpower. From cutting unused features to pruning your gem forest and embracing Tailwind CSS, learn how to avoid 'Context Bankruptcy' and keep your app lean. Adding features is exciting, but removing code is often where maintainability improves the most. 5. 🌐 Accessibility is coming to the official Rails guides. The Rails Foundation is drafting a dedicated guide covering semantic HTML, ARIA, Turbo interactions, forms, CSS, and testing (a first for the framework). If you've ever wondered what "accessible Rails" actually looks like in practice, this PR is worth bookmarking as it develops. 6. 📃 Everyone deserves a wiki, and Bridgetown 2.2 wants to make that a reality. Jared White's latest release brings wiki-focused capabilities to the static site generator, with seamless Markdown linking and a switch to the Falcon server for better performance. A solid update if you're building knowledge bases or documentation sites with Ruby. What's New in AI ?7. 💎 ActiveHarness is a new Ruby gem bringing production-grade LLM pipelines to Rails. It comes loaded out of the box: multi-provider support, agent pipelines, consensus-based "tribunals," lifecycle hooks, streaming, retries, and observability. Worth a look if you're experimenting with AI agents in Rails. 8. 🤖 A creative one: This post walks you through building an AI agent that can interpret and interact with Unix man pages using LLM techniques. It covers integrating ReadFile and Apropos tools, searching man pages, and using ActiveRecord for persistence, a fun example of pairing AI workflows with classic developer tooling. Building AI features into your app, but don't want to go it alone? 9. 🎨 Generative UI in Rails: Mikhail Samsonov's post explores how to build chat interfaces that render dynamic components (like cards and widgets) based on LLM output, using RubyLLM. A practical look at keeping HTML generation under control while letting the model drive the UI shape.
