Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo

# Ensure system is in ship-shape.

aptitude install git zsh libssl-dev zlib1g-dev libreadline-dev libyaml-dev

	var makeErrorHandler = function (msg) {
	//msg is the string passed via the call
	//the return anonyumous function is what is passed back to the callback of getData
	return function (error) {
	sendErrorToServer(error);
	showMessage(msg);
	};
	};

	getData(query, function (result) {

	var x = ['10','10','10'].map(parseInt);
	//x === [10,Nan,2]
	/*

	map returns a callback with 3 arugments
	arg[0] = elem;
	arg[1] = index;

	parseint takes 2 arguments
	arg[0] = string;

	//to use call getOrders.sum().then(function(sum){console.log(sum)});
	angular.service('getOrders',function ($http,$q) {
	return {
	sum: function () {
	var d = $q.defer();
	//can add try method here
	$http.get('/orders').success(function (data) {
	//assuming data is just json array of orders.
	var orders = data;
	var sumOfOrders = 0;
