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.

Instructions

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

	app.filter('capitalize', function() {
	return function(input, scope) {
	if (input!=null)
	input = input.toLowerCase();
	return input.substring(0,1).toUpperCase()+input.substring(1);
	}
	});

	#! /bin/sh
	#
	# /etc/rc.d/init.d/logstash
	#
	# Starts Logstash as a daemon
	#
	# chkconfig: 2345 20 80
	# description: Starts Logstash as a daemon

	### BEGIN INIT INFO

	app.filter('bytes', function() {
	return function(bytes, precision) {
	if (isNaN(parseFloat(bytes)) \|\| !isFinite(bytes)) return '-';
	if (typeof precision === 'undefined') precision = 1;
	var units = ['bytes', 'kB', 'MB', 'GB', 'TB', 'PB'],
	number = Math.floor(Math.log(bytes) / Math.log(1024));
	return (bytes / Math.pow(1024, Math.floor(number))).toFixed(precision) + ' ' + units[number];
	}
	});

	var parser = document.createElement('a');
	parser.href = "http://example.com:3000/pathname/?search=test#hash";

	parser.protocol; // => "http:"
	parser.hostname; // => "example.com"
	parser.port; // => "3000"
	parser.pathname; // => "/pathname/"
	parser.search; // => "?search=test"
	parser.hash; // => "#hash"
	parser.host; // => "example.com:3000"
