Maquina, the engine for Rails
Building apps over time, I found some work that needs to be done on every application: Authentication, Authorization, Mailers, etc. I started extracting this standard functionality into a Rails engine a few years ago. Later, tailwindscss, hotwire, stimulus, and phlex entered the picture, so I started the engine again with reusable UI patterns that take advantage of these tools. This is how Maquina was born.
Rubidity - A Ruby Dialect for Dumb (Blockchain) Contracts
Hello, some years ago I published a red paper to introduce sruby - Small, Smart, Secure, Safe, Solid & Sound (S6) Ruby to the world with a runtime (and gem) called universum. Now fast-forward and middlemarch (a.k.a. Tom Lehman) introduced dumb contracts on ethscriptions with the production code written in a dialect of Ruby called “Rubidity”. Q: Why do you choose ruby for dump contracts? A: Because you can create a mini-language that’s very similar to Solidity and will be easier for Solidity devs to use. Hear. Hear. Update I started a rubidity sandbox to experiment and study and learn together. join us.
Safe redirects in Rails 7
When enforcing canonical URLs, sometimes I find myself wanting to perform a redirect while retaining most of the params. It’s tempting to use params.merge to build the redirect in this case, but this is risky from a security standpoint. In this article I’ll explain how to perform redirects like these safely in Rails 7.

How to use React with Stimulus
If you’re using Hotwire in your Rails project (Turbo, Stimulus etc), it is reasonable to wonder if it’s possible to use a SPA framework like React or Vue in the same project, especially if you were building something with a high degree of interactivity. I wrote this article to explore how you might approach this problem if you wanted to take advantage of a framework like React, just on one page (or a few) in your app. [more inside]

Turbo Stream and personalized content
Ever wanted to render different content for the current user vs other users in partials being handled by Turbo? I frequently do, but I was surprised to find basically nothing online about how to do it. Here’s one approach that works pretty well:

ordserve gem - Ordinal Inscription Sandbox (Testing) Server / Service
is it ordinal summer? for easy testing of recursive inscriptions (in .SVG or .HTML) i have put together a new ordserve command-line tool and gem that starts up a (loopback) webserver and “automagically” downloads all recursions (referenced via /content/:id) the first-time only to save / cache locally. the index page has built-in (recursive) samples to get your started. happy recursing in ruby.
