The introduction to Reactive Programming you've been missing

(by @andrestaltz)

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.

Typesafe webinar notes: Spray & Akka HTTP

Presenter - Mathias Doenitz

Spary.io

embeddable http stack built on Akka actors
Just an HTTP integration layer, not for building full web apps

Category theory jargon cheat sheet

A primer/refresher on the category theory concepts that most commonly crop up in conversations about Scala or FP. (Because it's embarassing when I forget this stuff!)

I'll be assuming Scalaz imports in code samples, and some of the code may be pseudo-Scala.

Functor

A functor is something that supports map.

	/**
	* Pretty prints a Scala value similar to its source represention.
	* Particularly useful for case classes.
	* @param a - The value to pretty print.
	* @param indentSize - Number of spaces for each indent.
	* @param maxElementWidth - Largest element size before wrapping.
	* @param depth - Initial depth to pretty print indents.
	* @return

	private def prettyPrint(a: Any, indentSize: Int = 2, maxElementWidth: Int = 30, depth: Int = 0): String = {
