Rendering Incremental Points on Maps with Ruby and Rails January 30, 2026 When working with maps in Ruby or Ruby on Rails applications, most solutions assume that all geospatial data must be prepared upfront — usually as GeoJSON layers. While this works well for static datasets, it becomes inefficient when dealing with event-driven data such … Continue reading Rendering Incremental Points on Maps with Ruby and Rails
Making Maps with Ruby January 29, 2026 Static and animated cartography built directly from GeoJSON For a long time, generating maps from code meant working inside heavy ecosystems designed primarily for analysis. Those tools are powerful, but they are not always the right fit. In many practical scenarios, the problem is simpler and more concrete: … Continue reading Making Maps with Ruby
Understanding TypeProf: Design Goals, Limitations, and Effective Use in Ruby January 28, 2026 TypeProf is an official type inference tool for Ruby that has gained attention as part of the ecosystem surrounding RBS, Steep, and Sorbet. Despite this visibility, it is frequently misunderstood and often perceived as “not working” by first-time users. This article analyzes … Continue reading Understanding TypeProf: Design Goals, Limitations, and Effective Use in Ruby
January 27, 2026 From Disaster Prevention to High-Performance Maps On December 26, 2025, I published an article titled “Ruby at the Front Line of Disaster Prevention.” It was inspired by a real, uncomfortable fact: Tokyo Gas uses Ruby to protect millions of people during earthquakes. Not in theory. Not as a prototype. In production. That … Continue reading Ruby Rendering Seismic Observation Data
January 26, 2026 For many years, Ruby developers working with maps and geospatial data have relied on external tools or loosely coupled pipelines. ImageMagick, command-line utilities, and background processes became the norm, even though they were never designed to be deterministic GIS rendering engines. The result was fragile systems: slow, hard to debug, and difficult … Continue reading Stabilizing a Native Ruby GIS Engine with Docker, RuboCop, and CI
