App.stateManager = Ember.StateManager.create({
  start: Ember.State.extend({
    index: Ember.State.extend({
      route "/",

Looking at the preceding token when the lexer points to a '/'
character is insufficient to determine which context it's in. In
fact, you need to look at an arbitrary number of preceding tokens
to figure it out. This example demonstrates a case where we can
pump up the number of preceding tokens to an arbitrary size
before you can disambiguate your syntactic context.

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:

tj

/**
 * Module dependencies.
 */

var pkg = require('../package');
var env = process.env.NODE_ENV || 'development';

/**
 * Return setting `name`.

sudo apt-get update && apt-get install git-core curl build-essential openssl libssl-dev

git clone https://github.com/joyent/node.git
cd node
 
# 'git tag' shows all available versions: select the latest stable.
git checkout enter-a-version
 
# Configure seems not to find libssl by default so we give it an explicit pointer.
# Optionally: you can isolate node by adding --prefix=/opt/node

ES6 what can be shimmed and what not.

Currently only lists things that can be shimmed or are experimentally implemented

Note that for any kind of decent ES6 support we need an ES6 transpiler. A few projects are attempting this [Reference SO question][3]
