The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

Raw Attribute Strings

<div my-directive="some string" another-param="another string"></div>

Ubuntu 12.04, Ruby, Rails, Nginx, Unicorn and git-deploy

In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.

Server Setup

Create new server
Login to new server
- ssh root@IPaddress (you can also use the domain name if you have the DNS setup already)
- accept the RSA key

	(function () {
	var
	documentElement = document.documentElement,
	viewportFontSize, viewportHeight, viewportIsPortrait, viewportMax, viewportMin, viewportWidth;

	function getViewportFontSize() {
	var
	body = documentElement.appendChild(document.createElement('body')),
	iframe = document.createElement('iframe'),
	iframeDocument;

	# Downloads and applies a patch from Drupal.org.
	if [ -z "$1" ]
	then
	echo "You need to supply a URL to a patch file."
	exit
	fi

	URL=$1;

	inputs = %w[
	CollectionSelectInput
	DateTimeInput
	FileInput
	GroupedCollectionSelectInput
	NumericInput
	PasswordInput
	RangeInput
	StringInput
	TextInput

	All of these resources were extremely valuable as I researched regex, finite state machines, and regex in Ruby. Check them out, they're full of fantastic information!
