This is binary data captured from a car stereo and it's companion cd changer. The stereo updates it's screen with the cd track minutes and "seconds". Each row below corresponds to the "seconds". Column 1 is the seconds, 2 is binary, 3 is 2 inverted. The goal is figuring out how to generate the seconds from 0's & 1's without the table below.
seconds message inverted-message
4 110 001
5 00101 11010
6 10100 01011
7 01100 10011
8 11101 00010
9 00011 11100
10 10010 01101
11 0000101 1111010
12 1000100 0111011

I've got two arrays with identical elements in different orders that I need to compare and the order doesn't matter. Should I use sort or array subtraction?
Rehearsal --------------------------------------------
sort 1.140000 0.010000 1.150000 ( 1.166011)
subtract 0.610000 0.030000 0.640000 ( 0.672543)
----------------------------------- total: 1.790000sec
user system total real
sort 1.240000 0.010000 1.250000 ( 1.254706)
subtract 0.620000 0.030000 0.650000 ( 0.672024)

A handy Rails model for storing emails with a little logic to let a User have multiple email addresses but a single primary address.
class Email < ActiveRecord::Base
# Nope, it's not RFC compliant. F*** that regex.
# http://www.ex-parrot.com/~pdw/Mail-RFC822-Address.html
EmailRegex = /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i.freeze

# Public: The email address.
