Revisiting this experiment in pure Ruby GIS rendering.
Still one of my favorite projects:
drawing real cities from GeoJSON data using only Ruby + GD.No external GIS pipeline required.
“Ruby Can Draw Cities Now”

Testing Spinel (from RubyKaigi 2026) in real conditions 👇
Idiomatic Ruby → breaks (chaining, constants)
Explicit Ruby → works
Complex logic → unstable👉 Today it’s “Ruby written like C”
Not ready for contests like AtCoder, but a very interesting direction for Ruby performance.

In celebration of @rubykaigi I released Herb v0.10 today! 🌿
It ships with new primitives and provides the foundation that we need to build out production reactivity in ReActionView!
Along with a new Diffing Engine and ActionView-specific static analysis!
