Heroku Release Phase + Review Apps + Rails

This is a simplified, but fairly thorough, set of scripts and configuration to enable Heroku Release Phase for Rails apps. Further, this particular set up plays nicely with Heroku Review Apps in that the release phase script will:

Fail, loudly, if the DB does not yet exist.
Load the DB schema if the current schema version (as determined by bin/rails db:version) is 0.
Run DB migrations otherwise.

For a "normal" app that usually means it will run the DB migrations.

What is Pair Programming?

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>

Steps for Remote Pairing using tmux and ngrok

The following steps facilitate remote pairing using:

tmux which allows terminal sessions to be attached to different terminals, and
ngrok which provides secure tunnels to your localhost

1. Install tmux

OS X: brew install tmux
