Writing Ruby Bindings for C Libraries March 4, 2026 Building Native Extensions with C (and Rust) Ruby is known for its productivity and elegant syntax, but sometimes performance-critical tasks require lower-level languages. Fortunately, Ruby provides a powerful mechanism called C extensions, allowing Ruby code to call native C functions directly. This approach enables Ruby developers … Continue reading Writing Ruby Bindings for C Libraries
Image Processing in Ruby with GD: Exploring ruby-libgd v0.3.0 March 4, 2026 Image processing is usually associated with languages like Python or C++, but Ruby can also manipulate images efficiently thanks to bindings for native libraries. One of those libraries is libgd, a well-known C library used to dynamically generate and manipulate images such as … Continue reading Image Processing in Ruby with GD: Exploring ruby-libgd v0.3.0
Understanding Convolution Filters in Image Processing (and Adding Them to Ruby-LibGD v0.2.5) March 3, 2026 Today I implemented support for custom convolution filters in Ruby-LibGD, enabling the application of kernels such as blur, sharpen, and edge detection directly from Ruby. At first glance, this may look like just another image filter. In reality, convolution is … Continue reading Understanding Convolution Filters in Image Processing (and Adding Them to Ruby-LibGD v0.2.5)
The Production-Grade Ruby Microservices Stack (2026) March 2, 2026 Microservices don’t fail because of Ruby. They fail because of architecture. Most “microservices” I see in Ruby are: • HTTP chains tightly coupled together • Shared databases behind the scenes • No tracing • No event replay • No contract validation That’s not distributed architecture. That’s … Continue reading 🚀 The Production-Grade Ruby Microservices Stack (2026)

March 1, 2026 The Modern CLI Stack Beyond puts Ruby is often associated with web applications, background jobs, and scripting. But quietly — almost underground — a rich ecosystem has emerged for building modern, interactive, polished terminal applications. Not the old “print some text and parse ARGV” style. We’re talking about tools that feel closer … Continue reading 🚀 Terminal UX in Ruby: Beautiful Tools Without Leaving the Shell
February 27, 2026 For nearly three decades, CRuby (MRI) has been overwhelmingly a C codebase. That stability has been both a strength and a constraint. Recently, however, something genuinely new appeared inside the official Ruby repository: Parts of Ruby itself are now written in Rust. This is not theoretical, experimental folklore, or third-party tooling. It … Continue reading 🦀 Rust Inside Ruby Core: A New Systems Layer for MRI
Rack Is Still Innovating: The Backbone of Ruby’s Web Stack Keeps Evolving February 26, 2026 In recent months, much of the conversation in the Ruby ecosystem has focused on Ruby 4, Rails 8, concurrency, JIT compilers, and runtime capabilities. But while attention was on the language and frameworks, one critical component — present in every … Continue reading 🧱 Rack Is Still Innovating: The Backbone of Ruby’s Web Stack Keeps Evolving

When Ruby 4 was announced, most discussions focused on experimental features like Ractors, new JIT work, or isolation mechanisms. However, beneath the headline features lies a set of quieter improvements — refinements to the core language and standard library that directly affect everyday development. These changes may not generate conference talks, but they improve performance, … Continue reading 🧩 Ruby 4’s Quiet Improvements: Small Changes That Matter in Real Code
