The Timeline I started the Doctors app — the clinical assistance system I’ve been writing about recently — in October 2018 on Rails 5.2.1 with Ruby 2.5.1. Today it runs Rails 8.1 on Ruby 3.4.8. That’s every major Rails version — 5.2, 6.0, 6.1, 7.0, 7.1, 7.2, 8.0, 8.1 — across seven years. Here’s the full upgrade history, pulled straight from git: Date Rails Ruby ...

The Setup I’m building a multitenant order management system for cafes and restaurants.

Why even consider R2? There are plenty of good reasons to use AWS S3 in a Rails application, and for most teams it works perfectly well. However, one concern that comes up frequently is cost over time, especially when it comes to egress (data transferred out of the service). If your application serves many files—images, PDFs, backups, etc.—those costs can grow quickly. Because of that, I rec...
