Install ImageMagick for image conversion:

Install tesseract for OCR:

Or install without --all-languages and install them manually as needed.

### Locating UI elements ###

# By ID
<div id="coolestWidgetEvah">...</div>
element = driver.find_element_by_id("coolestWidgetEvah")
or
from selenium.webdriver.common.by import By
element = driver.find_element(by=By.ID, value="coolestWidgetEvah")

# By class name:

class ApplicationController < ActionController::Base

  ...
  #Problem:
  #In rails 3.0.1+ it is no longer possible to do this anymore;
  #  rescue_from ActionController::RoutingError, :with => :render_not_found
  #
  #The ActionController::RoutingError thrown is not caught by rescue_from.
  #The alternative is to to set a catch-all route to catch all unmatched routes and send them to a method which renders an error
  #As in http://techoctave.com/c7/posts/36-rails-3-0-rescue-from-routing-error-solution

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:

// Save this in a bookmarklet and click it on a page:

javascript:(function(){function d(a,c){document.body.style.webkitClipPath="circle("+a+"px, "+c+"px, "+b+"px)"}var b=90;window.addEventListener("mousemove",function(a){d(a.pageX,a.pageY)});window.addEventListener("mousewheel",function(a){if(a.shiftKey){a.preventDefault();var c=a.wheelDeltaY;b+=-c;b=0<c?Math.max(90,b):Math.min(b,window.innerHeight/2);d(a.pageX,a.pageY)}})})();

// Or paste this in the console and mouse over the page.
// SHIFT+mousewheel scroll makes the circle bigger/smaller.
