Launch Sublime Text 2 from the Mac OS X Terminal

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.

open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl

You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html

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:

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

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

Make /robots.txt aware of the Rails environment

You probably don't want Google crawling your development staging app. Here's how to fix that.

$ mv public/robots.txt config/robots.production.txt
$ cp config/robots.production.txt config/robots.development.txt

Now edit config/routes.rb to add a route for /robots.txt, and add the controller code.

// A simple trigger for the Adafruit Audio FX Sound Board
// For complete info on the sound board, see https://learn.adafruit.com/adafruit-audio-fx-sound-board/overview

/*
This is a simple test of a direct trigger of the Audio FX Sounds Board from an Arduino.

For my test, I used an Arduino Pro Mini running at 3.3v & 8mHz. Digital pin #4 of the Arduino
was connected to trigger pin #0 of the Sound Board, and I tied them to a common ground. I powered
Sound Board via a USB external battery for the initial tests, and the Arduino via the FTDI cable.
For later tests, I powered the Sound Board via the Arduino's VCC (3v) pin directly.
