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 |

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 🏎 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 |

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 |
