Extreme Software Portability as an Art Form

on YouTube ↗41m

" summary

WordPress explains how extreme portability means sacrificing modern conveniences to support the long tail: PHP compatibility across versions, 25 bundled libraries (Underscore, Backbone, jQuery, TinyMCE), and deliberate API stability so a 2008 plugin still works. Concrete moves include wrapping external libraries (new color picker as an external module), the theme customizer implemented with nested iframes to work on every theme, and staged releases every 3–5 months; metrics show 3 million updates, under 100 issues and sampling from 4,000 sites finds ~2% missing curl, ~50k missing JSON, ~500k missing GD.
