A summary of The Art of Readable Code by Dustin Boswell and Trevor Foucher

• Overall metric for readability: code should be written to minimise the time it would take someone else to fully understand it (able to modify the code and spot bugs) Ways to improve readability (ranked from easiest change to most time intensive)

1. Naming of variables and functions:
   • Use specific, descriptive, succinct names that say the entity's value or purpose
   • Use concrete names instead of abstract names e.g. canListenOnPort > serverCanStart
   • Add important attributes e.g. units or state e.g. unsafeUrl, safeUrl > url
   • Can use shorter variable names for smaller scope

# Base class to inherit from for objects to act like ActiveRecord::Base
# without using a database. Lets you use validations, errors, forms, routes.

# Example:
#   class Exporter < Base
#     attributes_accessor :email, :data
#   end
class Base

Hi everyone, I'm Chris Wanstrath.

When Jeremy asked me to come talk, I said yes.  Hell yes.  Immediately.  But
then I took a few moments and thought, Wait, why?  Why me?  What am I supposed
to say that's interesting?  Something about Ruby, perhaps.  Maybe the
future of it.  The future of something, at least.  That sounds
keynote-y.
