OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	setInterval(() => {
	let okayButtons = document.querySelectorAll('.okayButton');
	okayButtons.forEach(button => {
	if (getComputedStyle(button).display !== 'none') {
	button.click();
	}
	});
	}, 1000);

	import numpy as np
	import cPickle as pickle
	import gym

	# hyperparameters
	H = 200 # number of hidden layer neurons
	batch_size = 10 # every how many episodes to do a param update?
	learning_rate = 1e-4
	gamma = 0.99 # discount factor for reward
