Revisiting Garbage Collection in Ruby— First published in 2020 but now almost entirely rewritten for 2023, Ruby internals expert Peter Zhu takes us on a technical, but reasonably easy to follow, tour through Ruby 3.2’s GC implementation, its data structures, and how the phases of its lifecycle operate.

Deploying Rails Apps with Dokku— If you like the convenience of platforms like Heroku but want to run things on your own server, Dokku is a mature, open-source PaaS worth trying. The author has “tried to put together the ultimate Dokku + Ruby on Rails guide” and has done a good job IMHO, including adding Redis, Sidekiq, and deploying to ARM-based servers with Docker. (Much of it can be adapted to non-Rails apps, too.) Harrison Broadbent |
Pattern Matching on Ruby Objects— Introduced experimentally in Ruby 2.7 and becoming more established in Ruby 3.x, pattern matching is one of Ruby’s most intriguing syntax additions in recent years. It allows you to deeply match against values in structures and other objects and to do so depending on the shape of said objects.. Brad Gessler |
🎙️ JRuby's co-lead developer, Charles Nutter, was recently interviewed about the state of JRuby, how it survived the pandemic, and its CRuby-compatibility story. 🇯🇵 Kaigi on Rails 2023 is a Japanese language Rails event taking place both online and offline (in Tokyo) this October. You can submit a talk proposal until the end of this month, but you'll need to brush up on your Japanese. 📅 No Rails World ticket? No problem. Michael Buckbee suggests many other Ruby events to consider. 💡 Greg Molnar shares his latest Rails tip of the week by demonstrating how to run bundle audit and yarn audit on every PR and once each day to stay up to date with vulnerable dependencies. 🏎 Rails creator ▶️ DHH went on the Software Defined Talk podcast to talk about all sorts of things including DHH's background, how 37signals works, programming books DHH likes, 37signals' "leaving the cloud" journey, MRSK, and, oh, motor racing. |

A Comparison of AI Tools for Writing Rails Code— Can ChatGPT, Phind, Cody, Rix, or GitHub Copilot turn a simple bit of HTML into a helper for a Rails app? Mostly, yes, but it's still best to think of such tools as more like an eager intern rather than an expert pair programmer.. Lucian Ghinda |
▶ Broadcasting Progress from Background Jobs— Keeping users updated on the progress of asynchronous background jobs can be challenging, but Turbo and Stimulus make it easier than you might think in a Rails app. (22 minutes.) David Kimura (DriftingRuby) |
Creating a Basic Ruby GUI App with Glimmer— Glimmer is a DSL and framework for building GUI apps in Ruby that began in the JRuby world but is now happy with CRuby too (running atop LibUI). This is one developer’s slightly scrappy intro that may whet your appetite (full code). Mattias Velamsson |
Minitest::Snapshots 1.0: Jest-Style Snapshot Testing— “Think of it as VCR, but for any value,” says Matt. It’s a Minitest plugin that saves values encountered during the first run, saves them (if they can be serialized as YAML), then uses those as fixtures (in a sense) for future runs. It’s a curious idea. Matt Brictson |
