Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

madrobby

function isRetina(){
  return (('devicePixelRatio' in window && devicePixelRatio > 1) ||
    ('matchMedia' in window && matchMedia("(min-resolution:144dpi)").matches))
}

This is how I handle snappy taps on iOS.

I create a little jQuery/Zepto “plugin” function:

$.fn.onClickOrTouch = (callback) ->
  if window.ontouchend != undefined # insanely clever touch detection
    this.each -> this._touchMoveCount = 0
