In this tutorial I will teach you how to validate user input using an Express middleware module called express-validator.

express-validator is built on top of another open-source library called validator. validator is basically a library of validation functions. Some of it's popular functions include isEmail and isNumeric but you can see a full list here. express-validator makes all the functions in validator available in a way that works nicely with Node and Express.

###Installation

Installing express-validator is easy when you use npm. Just input the following command:

npm install express-validator

#Pros and cons of GNOME, in my view

##Pros

Ubuntu...
Is it just me, or does Chrome font render really nice in GNOME?

GDM interface (login screen) is disgusting

#How to upgrade to GNOME 3.16

I have been using Ubuntu GNOME for the last week or so. It came pre-installed with GNOME 3.14 but that is not the latest version of GNOME, 3.16 is. In this short tutorial, I will teach you how to upgrade to GNOME 3.16. For a list of the new features, check out the release notes. I like GNOME 3.17 more than its predecessor but then again, I have only been using it for a couple of hours. I do not know how stable this is and I implore you to be cautious. That said, it does seem to work pretty good.

#How to Install Node on Ubuntu, the Right Way

When I first started using Ubuntu a few months ago, I instinctively installed Node using these commands:

curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash -
sudo apt-get install nodejs

This is not the correct way to install Node. Installing Node this way leads to two problems in my experience:

	html,
	body,
	body div,
	span,
	object,
	iframe,
	h1,
	h2,
	h3,
	h4,

	sudo apt-get update
	sudo apt-get upgrade
	sudo apt-get dist-upgrade

	sudo add-apt-repository ppa:webupd8team/sublime-text-3
	sudo add-apt-repository ppa:mutate/ppa
	sudo add-apt-repository -y ppa:ricotz/docky
	sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner"
	sudo apt-get update

	function identity(num) {
	return num;
	}

	function add(num1, num2) {
	return num1 + num2;
	}

	function mul(num1, num2) {
	return num1 * num2;
