I couldn't find this documented anywhere, but the option exists and lives in the code!

If you're using python, selenium, and phantomjs, somewhere in your code you have a line like this:

from selenium import webdriver
driver = webdriver.PhantomJS()

How to capture WebGL/Canvas by piping data over a websocket.

This Gist builds on https://gist.github.com/unconed/4370822 from @unconed.

Instead of the original method which writes to the browsers sandboxed filesystem here we use a websocket connection provided by websocketd to pipe image data to a short python script that writes out the .png files to disk.

Install websocketd

So you're trying to build a nice slide-in menu. Something that shows up from the bottom of your app when a user clicks a menu button. Here are a collection of things I wish I had known a few hours ago.

You can't do this with just CSS (or you shouldn't)

You need to have a bit of JavaScript to change a class on the element you're trying to animate.

You need a position: relative parent, a regular child div, and a position: absolute child with left and bottom set.

If you don't have a position: relative parent, your absolutely positioned div (the one you want to slide on screen) may not

	Descriptions:

	ready event fires twice
	backbone router runs twice
	router won't render sub-pages

	Long description:

	My backbone app wouldn't render any pages that were not at the root of the
	tree. For example /robots would render fine but /robots/id/1 would not.
