Rails 3.2 ships with a simple FileWatcher that only reloads your app if any of the files changed.

Besides, it also provides a mechanism to hook up your own file watcher mechanism, so we can use tools like FSSM that hooks into Mac OS X fsevents. This is an example on how to hook your own mechanism (you need Rails master, soon to be Rails 3.2):

1. Copy the 2_file_watcher.rb file below to lib/file_watcher.rb

2. Add the following inside your Application in config/application.rb

if Rails.env.development?

dwt

# Run via: ruby -rubygems app.rb
require 'sinatra'
require 'haml'

disable :logging

get '/' do
	title = "Drag'n'drop issue reduction"
	haml :index
end

#!/usr/bin/env ruby
#Instructions: ruby < <(wget -nv -O - <link_to_raw_file>)
#where link_to_raw_file is the raw url of this file
require 'yaml'
puts(Dir.glob('/home/*/app/current/config/sphinx.yml').inject([]) do |a, file|
  a << [YAML.load_file(file)['production']['port'], file]
end.sort_by{|a| a[0]}.map{|a| a.join(' -> ')})

#Four Ways To Do Pub/Sub With jQuery and jQuery UI (in the future)

Between jQuery 1.7 and some of work going into future versions of jQuery UI, there are a ton of hot new ways for you to get your publish/subscribe on. Here are just four of them, three of which are new.

(PS: If you're unfamiliar with pub/sub, read the guide to it that Julian Aubourg and I wrote here http://msdn.microsoft.com/en-us/scriptjunkie/hh201955.aspx)

##Option 1: Using jQuery 1.7's $.Callbacks() feature:

$.Callbacks are a multi-purpose callbacks list object which can be used as a base layer to build new functionality including simple publish/subscribe systems. We haven't yet released the API documentation for this feature just yet, but for more information on it (including lots of examples), see my post on $.Callbacks() here:
