Learn Enough Ruby
summary
Live coding shows how to go from irb experiments to a packaged rubyconf_palindrome gem, using bundler, mini‑test and a red‑green‑refactor TDD loop. The demo implements string methods and regex scan to ignore punctuation and case, runs tests, installs the gem locally and plugs it into a small Sinatra web app that actually detects phrase palindromes. The workflow and commands are concrete: irb, def, bundle gem, rake test, require, rerun — and the app works.
