The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

	Deploying a Rails 3 App with EC2 + S3 + Ubuntu + Capistrano + Passenger
	=======================================================================

	EC2 Setup
	---------
	1 Launch New ec2 instance - ami-1634de7f
	2 Create elastic IP [ELASTIC_IP] and associate it with instance
	3 go to domain registrar DNS settings, @ and www to ELASTIC_IP
	4 set the `:host` in `config/deploy.rb` to ELASTIC_IP

	# Guide
	# Configure the essential configurations below and do the following:
	#
	# Repository Creation:
	# cap deploy:repository:create
	# git add .
	# git commit -am "initial commit"
	# git push origin master
	#
	# Initial Deployment:

	tell application "SystemUIServer"
	set actionSelected to the button returned of (display dialog "What you want to do?" buttons {"Send file", "Receive file"} default button 2)

	if actionSelected = "Send file" then
	set filepath to POSIX path of (choose file)
	display dialog "Please enter IP address of receiver:" default answer ""
	set ipAddress to text returned of result
	if ipAddress = "" then
	repeat
	display dialog "IP address cant be blank,Please enter IP address of receiver:" default answer ""

	server {
	listen 443;
	server_name server_url;
	index index.html index.htm;
	root /home/deploy/cingo/public;
	ssl on;
	ssl_certificate path/to/www.example.org.crt;
	ssl_certificate_key path/to/www.example.org.key;

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console
