The introduction to Reactive Programming you've been missing

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.

Add remote_syslog to your Gemfile
Add papertrail.rake to lib/tasks
Add remote_syslog.yml to config/
Add before_restart.rb to deploy/
Set the PAPERTRAIL_PORT ENV var to the one provided by Papertrail for your system

Inspiration from Scott W. Bradley

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	require 'net/http'

	# WARNING do not use this; it works but is very limited
	def resolve url
	res = Net::HTTP.get_response URI(url)
	if res.code == '301' then res['location']
	else url.to_s
	end
	end

	require "etc"
	require "thread"

	Enumerator.class_eval do
	# Process an enumerator using a simple thread pool
	#
	# `of:` is pool size, defaults to detecting number of CPUs
	#
	# Caveat: Enumerator#map may yield results out of order. Work is processed in
	# order, but apparently #map concatenates the results however it likes. This

	/* Build this with:
	* gcc desktopsearch.m -o desktopsearch -ObjC -framework Cocoa
	*/

	#include <Cocoa/Cocoa.h>

	int main(int argc, char** argv) {
	NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

	if (argc == 2) {

	# minimal rails3 app

	require 'action_controller'

	Router = ActionDispatch::Routing::RouteSet.new
	Router.draw do
	root :to => 'site#index'
	end

	class SiteController < ActionController::Metal

	if ENV['RAILS_ENV'] && !defined?(RAILS_ENV)
	Object.const_set("RAILS_ENV", ENV['RAILS_ENV'])
	end

	# Require any additional compass plugins here.
	require 'grid-coordinates'
	require 'compass-fancybox-plugin'
	require 'susy'

	project_type = :rails
