Play the FF Prelude on your PC speaker, because why not. Requires `beep`.
const child_process = require('child_process');
const beep = (f, l) => { child_process.spawnSync('beep', ['-f', f, '-l', l]); };
const freq_for_note = (root_freq, step, steps_per_octave = 12) => root_freq * 2**(step/steps_per_octave);
const invert_chord = (steps, steps_per_octave = 12) => steps.slice(1).concat(steps[0] + steps_per_octave);
const rangeTo = n => [... Array(n).keys()];
const note_length = 60*1000/320;
const root_freq = freq_for_note(440, 3 - 3*12); // C2 derived from A440

After the fact, realized that iTunes already does what I was starting to suspect I ultimately wanted out of this, so this probably won't be any further refined. But worked for task at hand.

I was curious about how the different input latencies in TVs I was looking at would manifest in shooter games. This was small result.

gadtfly / `Bundler could not find compatible versions for gem`.md
Last active May 27, 2016 03:57

###Short answer:

The instructions are out of date, but there is no sufficiently significant difference between 4.2.5 and 4.2.6 to worry about it.

Either do bundle update (which should make everything able to use 4.2.5), or (as you figured) revert to the original specification you found in your Gemfile (ie, change the line back to gem 'rails', '4.2.6')
