Ruby (3.3) on Rails (1.0) — Rails 1.0 was released about eighteen years ago (I know!) – just a day after Ruby 1.8.4. Things have changed a bit since then [citation needed], but surely a modern Ruby could still run Rails 1.0? Sort of..! (It’s funny to see bundler being used, though, as it didn’t even exist at the time, and even RubyGems itself wasn’t a default part of Ruby 1.8!)
