Keynote: Multitudes
summary
Argues that Ruby has two engineering personas — application developers and gem developers — backed by a rough count of ~90,000 gems versus fewer than 150 open‑source Rails apps, so library constraints dominate contributor work. Live builds a tiny RSpec‑style gem called spectroscopy using bundler, implements expect/to_equal and before hooks, hits a test pollution bug, then refactors into DescribeBlock/ItBlock to fix scoping. Concludes these constraints shape different code structures and that app‑side contributors are essential to healthy libraries.
