Composability, Abstraction, Reusability
Category Theory is a higher-level language.
Not a practical, executable language.

Sandi Metz' four rules from Ruby Rogues episode 87. Listen or read the transcript: http://rubyrogues.com/087-rr-book-clubpractical-object-oriented-design-in-ruby-with-sandi-metz/
  1. Your class can be no longer than 100 lines of code.
  2. Your methods can be no longer than five lines of code.
  3. You can pass no more than four parameters and you can’t just make it one big hash.
  4. When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.

You can break these rules if you can talk your pair into agreeing with you.

Deploy script for Heroku apps
#!/usr/bin/env ruby
# This is a basic deploy script for Heroku apps.
# It provides a structure you can use to expand on
# and add your own prereqs and deploy tasks.
#
# It basically ensures that:
# 1. There are no uncommited files
# 2. You can ssh to github
# 3. You can connect to heroku
