Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

12 factor app configuration vs leaking environment variables
App configuration in environment variables: for and against
For (some of these as per the 12 factor principles)
1) they are are easy to change between deploys without changing any code
2) unlike config files, there is little chance of them being checked
into the code repo accidentally
3) unlike custom config files, or other config mechanisms such as Java
