Why I hate TypeScript

Warning: These views are highly oppinated and might have some slightly incorrect facts. My experience with typescript was about 2 weeks in Node and a week in angular2.

Not Standard

TypeScript is implementing their own take on JavaScript. Some of the things they are writing will likely never make it in an official ES* spec either.

Technologies that have competing spec / community driven development have a history of failing; take: Flash, SilverLight, CoffeeScript, the list goes on. If you have a large code base, picking TypeScript is something your going to be living with for a long time. I can take a bet in 3 years JavaScript will still be around without a doubt.

Its also worth noting that they have built some things like module system and as soon as the spec came out they ditched it and started using that. Have fun updating!

AWS ELB with Node.js and WebSockets

This assumes that:

You are using Nginx.
You want to accept incoming connections on port 80.
Your Node.js app is listening on port 3000.
You want to be able to connect to your Node.js instance directly as well as via the load balancer.

####1. Create load balancer

Convert a Cordova/Ionic project to a Crosswalk project

Converts an existing Cordova/Ionic project to a Crosswalk project. When the script is done running, you should have a fat 40MB APK file in platforms/android/ant-build.

This assumes you have the following already installed: cordova, ant, android, and that your ANDROID_HOME is set to point to the Android SDK.

This will work on both x86 and ARM. If you want to build two separate APKs so that they're smaller, then modify the script; the script at least shows how it works.

Step 1: download the "Cordova Android" libraries from the Crosswalk downloads page. You don't need anything except for the "Cordova Android" ones.

	(comment ; Fun with transducers, v2

	;; Still haven't found a brief + approachable overview of Clojure 1.7's new
	;; transducers in the particular way I would have preferred myself - so here goes:

	;;;; Definitions
	;; Looking at the `reduce` docstring, we can define a 'reducing-fn' as:
	(fn reducing-fn ([]) ([accumulation next-input])) -> new-accumulation
	;; (The `[]` arity is actually optional; it's only used when calling
	;; `reduce` w/o an init-accumulator).

	* POST to create a new user.

	exports.create = function *(){
	var body = yield parse(this);

	// password
	var pass = body.password;
	assert(pass, 400, 'password is required');
