Unlocking the Secrets of Rails Secrets and Credentials

If you are like many (most?) of us, you have encountered Rails Credentials/Secrets and secret_key_base and may have been left a bit (or more) confused.

This post is an attempt to remove some of that confusion by

Cheat Sheet: Simple Authentication in Rails 6 with `has_secure_password`

The goal of this cheatsheet is to make it easy to add hand-rolled authentication to any rails app in a series of layers.

First the simplest/core layers, then optional layers depending on which features/functionality you want.

	# synthio_midi_synth.py - pretty usable MIDI-controlled synth using synthio in CircuitPython
	# 11 May 2023 - @todbot / Tod Kurt
	# Uses cheapie PCM5102 DAC on QTPY RP2040
	# Video demo: https://www.youtube.com/watch?v=N-PbbWWDE6k
	# Features:
	# - midi velocity controls attack rate (gentle press = slow, hard press = fast)
	# - notes have small random detune on all oscillators to reduce phase stacking
	# - adjustable number of detuned oscillators per note 1-5 (midi controller 83)
	# - five selectable waveforms: saw, squ, sin, noisy sin, noise (midi controller 82)
	# - vibrato depth on mod wheel (midi controller 1)
