Ruby 4.0 Is Here. Why Is AI Still Writing Ruby 3.0? June 17, 2026 Artificial intelligence has become an indispensable tool for Ruby developers. We ask AI assistants to write methods, refactor services, generate RSpec tests, explain stack traces, and even architect new features. For many developers, AI is no longer an experiment—it's part of … Continue reading Ruby 4.0 Is Here. Why Is AI Still Writing Ruby 3.0?
The Hidden DSL Inside Every Rails Model June 10, 2026 Most Rails developers use belongs_to, has_many, scope, and validates every day. We type them almost without thinking. class User < ApplicationRecord belongs_to :company validates :email, presence: true scope :active, -> { where(active: true) } end But here's something interesting: None of those are Ruby keywords. … Continue reading The Hidden DSL Inside Every Rails Model
June 7, 2026 When Ruby receives a method call, it follows a well-defined search path to determine where that method is implemented. Most developers learn inheritance early, but fewer take the time to understand the complete method lookup path, also known as the ancestor chain. Understanding this mechanism can make debugging easier, clarify how Rails … Continue reading Ruby’s Ancestor Chain: Why prepend Cuts the Line
The Original Sin, the Scorpion, and Local AI June 1, 2026 For the last few weeks, I have been experimenting with local AI models to help me develop and maintain Ruby projects. Built for Ruby on Rails Build Maps WithoutGoogle APIs Generate beautiful production-ready maps directly from your Rails backend. Fast rendering, zero external dependencies, … Continue reading The Original Sin, the Scorpion, and Local AI
Turning Years of Ruby Knowledge Into a Local Coding Assistant June 1, 2026 Introduction Over the years, most Ruby developers accumulate a vast amount of knowledge. Not just source code, but articles, documentation, experiments, bug fixes, pull requests, design decisions, and lessons learned from maintaining production systems. The problem is that this knowledge often remains … Continue reading Turning Years of Ruby Knowledge Into a Local Coding Assistant
Running AI Locally for Ruby Development: A Practical Guide with Ollama, Aider, and Your Own Codebase May 28, 2026 Ruby Stack News — by Germán Silva There's a quiet revolution happening in developer tooling, and it doesn't require a cloud subscription, an API key, or sending your proprietary code to someone else's server. Over the … Continue reading Running AI Locally for Ruby Development: A Practical Guide with Ollama, Aider, and Your Own Codebase
Exploring Ruby’s OpenSSL stdlib internals: from C bindings to Ruby APIs May 27, 2026 Ruby ships with a standard library gem named openssl, responsible for exposing cryptographic primitives, TLS/SSL sockets, certificates, digests, encryption, and secure communication APIs directly to Ruby developers. Built for Ruby on Rails Build Maps WithoutGoogle APIs Generate beautiful production-ready maps directly … Continue reading Exploring Ruby’s OpenSSL stdlib internals: from C bindings to Ruby APIs
May 26, 2026 Ruby’s elegance hides an extremely sophisticated runtime underneath. Features like blocks, lambdas, closures, binding, method(:foo), and even &:to_s rely on a dense set of VM internals implemented in CRuby’s proc.c. This file is one of the best entry points for understanding how Ruby models executable code objects. The source analyzed here comes … Continue reading Understanding Ruby Proc Internals Through proc.c
May 21, 2026 How MRI Really Implements include, prepend, extend, Singleton Classes and Method Lookup Ruby’s object model looks elegant from the outside: module Logging def call puts "before" super end end class Service prepend Logging def call puts "service" end end But internally, MRI/CRuby performs a surprising amount of machinery to make this work. … Continue reading Inside Ruby’s Object Model
May 18, 2026 Most Ruby developers use ranges every day: (1..5) ('a'..'z') (1...) (..10) They feel lightweight, expressive, and almost deceptively simple. Built for Ruby on Rails Build Maps WithoutGoogle APIs Generate beautiful production-ready maps directly from your Rails backend. Fast rendering, zero external dependencies, full control.
