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:

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 = [email protected]: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:

	final class SampleViewController: StoryboardBackedViewController {
	// Unfortunately this must be an IUO var, so that we can set the value after super.init
	private var member: Foo!

	// Proper dependency injection in a storyboard backed VC!
	init(foo: Foo) {
	super.init(storyboardIdentifier: "SampleViewControllerIdentifier")

	// We have to set the members after calling super.init, since it changes the instance of `self`.
	self.member = foo

	import CoreData

	protocol Fetchable
	{
	typealias FetchableType: NSManagedObject

	static func entityName() -> String
	static func objectsInContext(context: NSManagedObjectContext, predicate: NSPredicate?, sortedBy: String?, ascending: Bool) throws -> [FetchableType]
	static func singleObjectInContext(context: NSManagedObjectContext, predicate: NSPredicate?, sortedBy: String?, ascending: Bool) throws -> FetchableType?
	static func objectCountInContext(context: NSManagedObjectContext, predicate: NSPredicate?) -> Int
