#Introduction

Developing Chrome Extensions is REALLY fun if you are a Front End engineer. If you, however, struggle with visualizing the architecture of an application, then developing a Chrome Extension is going to bite your butt multiple times due the amount of excessive components the extension works with. Here are some pointers in how to start, what problems I encounter and how to avoid them.

Note: I'm not covering chrome package apps, which although similar, work in a different way. I also won't cover the page options api neither the new brand event pages. What I explain covers most basic chrome applications and should be enough to get you started.

Learn you a Haskell - In a nutshell

This is a summary of the "Learn You A Haskell" online book under http://learnyouahaskell.com/chapters.

1. Introduction

Haskell is a functional programming language.

	// set-up a connection between the client and the server
	var socket = io.connect();

	// let's assume that the client page, once rendered, knows what room it wants to join
	var room = "abc123";

	socket.on('connect', function() {
	// Connected, let's sign-up for to receive messages for this room
	socket.emit('room', room);
	});

	# ... or force ignoredups and ignorespace
	HISTCONTROL=ignoredups:ignorespace

	# ~/.profile: executed by the command interpreter for login shells.
	# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
	# exists.
