Writing Ruby Bindings for C Libraries

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

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)

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)

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) →

🦀 Rust Inside Ruby Core: A New Systems Layer for MRI

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 →
