Why I’m sticking with Rails, at least for now.
This is my journey with two leading web development frameworks: Rails and Elixir. Having invested years in Rails, I ventured into Elixir, captivated by its claims of high performance, resilience, and distributed systems. I admired Elixir and its Phoenix framework but encountered complexities when revisiting past code. On returning to Rails, I experienced greater intuitiveness and efficiency, especially with the innovative Hotwire design. Despite the unique advantages of Elixir, such as its Ecto library for complex queries, I felt more aligned and efficient with Rails. Ultimately, I decided to rewrite my Elixir-based project, Rauversion, in Rails, completing 90% in just two weeks, and I’ve had the opportunity to contrast the strengths and weaknesses of both ecosystems.

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. https://mariochavez.io/desarrollo/2023/08/08/maquina-the-engine-for-rails/
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

In this article I’ll explain how to perform redirects like these safely in Rails 7. https://mattbrictson.com/blog/safe-rails-redirects
