A replacement for "livereload" gem on OS X

This script is a replacement for livereload server component designed for working with Rails. It watches the filesystem with FS Events (Mac OS X) rather than with EventMachine. This is better for large projects for wich EventMachine fails with "too many open files" exception.

Sass is supported; .sass files can also be stored in "app/styles/" directory. Compass is detected if "config/compass.rb" file exists.

Installation:

Download this script to somewhere in your PATH and make it executable. You can name it something different than "livereload" if you want to try this and the official gem executable in parallel.

# Or, if you're using RSpec 2 / Rails 3, the contents should be the following

How to setup Heroku Hostname SSL with GoDaddy SSL Certificate and Zerigo DNS
Heroku recently added an exciting new 'Hostname SSL' option.  This option offers the broad compatibility of IP-based SSL, but at 1/5 the price ($20 / month at the time of this writing).  
 
The following tutorial explains how to use Heroku's new 'Hostname SSL' option on your Heroku project.  Before we begin, let's list what we're using here:

    * Heroku Hostname SSL
    * GoDaddy Standard SSL Certificate
    * Zerigo DNS

# First configure your models to use Amazon s3 as storage option and setup the associated S3 config.
# Then add the classes your want to migrate in the klasses array below.
# Then run rake paperclip_migration:migrate_to_s3
# Should work but this is untested and may need some tweaking - but it did the job for me.

namespace :paperclip_migration do  
  desc "migrate files from filesystem to s3"

    klasses = [:model_1, :model_2] # Replace with your real model names. If anyone wants to this could be picked up from args or from configuration.
