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:

Just a dump of handy live templates I use with IntelliJ. They should also work with WebStorm.

	// scala 2.7 simple type constraint. This can only constrain a type parameter of this function.
	// Below, in ListW.sumint28, we can't use this approach because we want to constrain T,
	// a type param of the enclosing trait.
	def sumint27A[T <: Int](l: List[T]) : Int = l.reduceLeft((a: Int, b: Int) => a + b)

	trait IntLike[X] extends (X => Int)
	object IntLike {
	implicit val intIntLike: IntLike[Int] = new IntLike[Int] { def apply(x: Int) = identity(x) }
	}

	var flattenObject = function(ob) {
	var toReturn = {};

	for (var i in ob) {
	if (!ob.hasOwnProperty(i)) continue;

	if ((typeof ob[i]) == 'object') {
	var flatObject = flattenObject(ob[i]);
	for (var x in flatObject) {
	if (!flatObject.hasOwnProperty(x)) continue;
