If you add a dir directly under app/

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

If you add a dir under app/something/

Sandi Metz’ rules for developers

1. Your class can be no longer than a hundred lines of code.
2. Your methods can be no longer than five lines of code
3. You can pass no more than four parameters and you can't just make it one big hash.
4. In your controller, you can only instantiate one object, to do whatever it is that needs to be done.
5. Your view can only know about one instance variable.
6. Your Rails view should only send messages to that object i.e., no Demeter violations.[ "thunder dome principal". Translated: one model in, one model out! ]
7. Rules are meant to be broken if by breaking them you produce better code. [ ...where "better code" is validated by explaining why you want to break the rule to someone else. ]

# This capistrano deployment recipe is made to work with the optional
# StackScript provided to all Rails Rumble teams in their Linode dashboard.
#
# After setting up your Linode with the provided StackScript, configuring
# your Rails app to use your GitHub repository, and copying your deploy
# key from your server's ~/.ssh/github-deploy-key.pub to your GitHub
# repository's Admin / Deploy Keys section, you can configure your Rails
# app to use this deployment recipe by doing the following:

Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.

Initial setup
