Make tooltips work on iOS by using touch events and ignoring mouse events
;(function ($) {
var wasTapped = function wasTapped (element) {
var touchStart = element.data('lastTouchStart')
var touchEnd = element.data('lastTouchEnd')
return (
touchStart && touchEnd &&
touchEnd.timeStamp - touchStart.timeStamp <= 500 && // duration
Math.abs(touchEnd.pageX - touchStart.pageX) <= 10 && // deltaX
Math.abs(touchEnd.pageY - touchStart.pageY) <= 10 // deltaY
)

Created April 17, 2013 00:54
This demonstrates a bug in the Rails implicit counter_cache. When creating a record with nested records via a nested form, it does not increment the {child}s_count, but when deleting via a nested form, it decrements the field.
require 'rubygems'
require 'active_record'
# Print out what version we're running
puts "Active Record #{ActiveRecord::VERSION::STRING}"
# Connect to an in-memory sqlite3 database
ActiveRecord::Base.establish_connection(
:adapter => 'sqlite3',
:database => ':memory:'
