GitHub vs Ruby on Rails

Ruby on Rails started first, in 2004, 3 years before GitHub.

Why GitHub lasted

  • It is where the code is. Resume, package registry, CI, identity, and the social graph of software.
  • Microsoft bought it and, against every instinct of 2018 Twitter, did not kill it.

Why Ruby on Rails lasted

  • It taught a decade of startups that a web app is a folder with opinions.
  • Shopify, GitHub, Basecamp, and a long tail of apps that still print money in Ruby.
