Script to control keyboard led lights for Macbook Pro on Arch Linux

	Controlling the keyboard led lights on a Macbook Pro running linux is harder than it should be.

	For ...reasons the bundled `kbdlight` doesn't work, so we're left with no option but to roll
	up our sleaves and get our hands dirty. Fortunately various bash commands and `bc` makes this
	task pretty trivial so here is a script to control the brightness.

	This script supports the following api:

	$ kbdlight -set 10
	$ kbdlight -set +10

Example MasterProxy for Elixir Umbrella applications supporting websockets

	defmodule MasterProxy.Application do

	Custom Cowboy specification to support hosting multiple Phoenix apps within the same umbrella,
	all served via the same port. This is only really necessary if you're deploying your umbrella
	to a restricted hosting environment like Heroku where they only expose 1 port per dyno.

	Don't for get to configure your endpoints, something like this should work:

	config :myapp_web, MyAppWeb.Endpoint,

When you want to filter by date, but you've only got a datetime property, this will help you cast your datetime

	# frozen_string_literal: true
	class Things < ApplicationRecord
	scope :filter_after_date, -> (date) {
	where(created_at_as_date.gteq(date))
	}
	scope :filter_before_date, -> (date) {
	where(created_at_as_date.lteq(date))
	}
	def self.created_at_as_date
	Arel::Nodes::NamedFunction.new "DATE", [ arel_table[:created_at] ]
