🧩 Ruby 4’s Quiet Improvements: Small Changes That Matter in Real Code

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 →

🧠 Pluggable Garbage Collectors in Ruby: Exploring the New Modular GC API

February 23, 2026 Ruby has traditionally shipped with a single, built-in garbage collector tightly coupled to the VM. With Ruby 3.4, that assumption begins to change. Feature #20470 introduces an experimental Modular Garbage Collector API, allowing CRuby to load alternative GC implementations at runtime. This marks one of the most significant architectural shifts in Ruby’s … Continue reading 🧠 Pluggable Garbage Collectors in Ruby: Exploring the New Modular GC API →

🌍 Rendering Maps by Name: Symbolic Geographic Extents in Ruby

Working with maps usually means working with numbers — lots of numbers. If you want to render a map of a country, region, or continent, you normally need to know its exact bounding box: bbox = [-73.6, -55.1, -53.6, -21.7] # Argentina Not exactly readable. Not memorable. Not friendly. What if you could just say: … Continue reading 🌍 Rendering Maps by Name: Symbolic Geographic Extents in Ruby →
