Split a hash into multiple equal-sized hashes
# Extend hashes by adding one method that allows you to split a hash into an array of equal-sized hashes.
# Filter items to be included in the result by adding a selecting block that returns true
# if the key/value is to be kept.
# Per the usage example, return values are not ordered unless you're using Ruby 1.9
# usage:
# a = {1 => 'a', 2 => 'b', 3 => 'c', 4 => 'd', 5 => 'e'}
# a.split_into(3) {|k,v| k.instance_of?(Integer)}

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.
