SVG Generation in Ruby: A Practical Guide March 16, 2026 Recently, I created ruby-libgd and libgd-gis for raster graphics generation in cartography. But as I worked on these tools, I realized the landscape of web graphics has shifted significantly. Today's web demands interactive, scalable, responsive visualizations. That's where SVG (Scalable Vector Graphics) comes in. This … Continue reading SVG Generation in Ruby: A Practical Guide
March 16, 2026 Published on RubyStackNews After the last article, Jupyter proved to be an awesome sandbox for testing code interactively. I spent the entire weekend asking myself one question: can Ruby render a real 3D plot? I started convinced the answer was no. By Sunday night, ruby-libgd had proven me wrong. The question nobody … Continue reading Ruby for Data Science — Is It Possible?
Plotting Mathematical Functions in Ruby, Inside Jupyter March 13, 2026 ruby-libgd: Scientific Plotting Comes to Ruby The Envy We Never Talked About Anyone who has spent serious time with Ruby and then watched a Python developer type plt.show() to produce a beautiful Matplotlib graph in a Jupyter notebook knows the feeling. It is not quite … Continue reading Plotting Mathematical Functions in Ruby, Inside Jupyter
Choosing the Right Debugger March 12, 2026 A Ruby Developer's Guide to TracePoint, ISeq, and why your choice of debugger affects more than just comfort If you write Ruby, you debug Ruby. Whether it's a subtle off-by-one error in a data pipeline or a race condition buried in a Rails controller, debugging is as much … Continue reading Choosing the Right Debugger: TracePoint, ISeq, and why your choice of debugger affects more than just comfort
March 11, 2026 What if you could run a fully functional Rails application — backend, database, file storage, and all — directly inside a browser tab, with zero servers? WebAssembly (Wasm) makes this possible. By compiling Ruby and Rails into a Wasm module, the entire application stack executes client-side. This post explores a practical journey: … Continue reading Ruby on Rails on WebAssembly: A Full-Stack, In-Browser Journey
Ruby-LibGD Reaches 3,000 Downloads: A Milestone in Ruby Image Generation March 9, 2026 Open-source development is often a marathon, not a sprint. Today, ruby-libgd, a Ruby library for image generation, has reached an exciting milestone: 3,000 downloads. This achievement reflects not only adoption but also the sustained effort behind a library that brings dynamic image … Continue reading Ruby-LibGD Reaches 3,000 Downloads: A Milestone in Ruby Image Generation
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
