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:

	var Option = require('fantasy-options')
	var Some = Option.Some;
	var None = Option.None;

	var Compose = function(x){
	this.val = x;
	}

	Compose.prototype.map = function(f){
	return new Compose(this.val.map(function(u){return u.map(f); }));

	# A simple Makefile alternative to using Grunt for your static asset compilation
	#
	## Usage
	#
	# $ npm install
	#
	# And then you can run various commands:
	#
	# $ make # compile files that need compiling
	# $ make clean all # remove target files and recompile from scratch

	sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES;
	sudo defaults delete /Library/Preferences/com.apple.windowserver DisplayResolutionDisabled;

	// by the way, you need to logout and log back in for this to take effect. Or at least that's what
	// Quartz Debug says. Who knows, maybe it's lying?

	// P.S. Go to [Apple menu --> System Preferences --> Displays --> Display --> Scaled] after logging
	// back in, and you'll see a bunch of "HiDPI" resolutions in the list to choose from.
