Find proximity of inauguration day to MLK

	import calendar

	# Martin Luther King, Jr. Day was established in 1986, so the first presidential inauguration to be affected was
	# George Bush I on Jan 20, 1989. King's birthday was the 15th, but we celebrate it on the 3rd Monday of each January.
	# So, to me, the interesting days would be when MLK is on the 19th, 20th, or 21st.

	# Let's go until the year 2089, just to get a full 100-year period since MLK started.
	start_year = 1989
	end_year = 2089

Reset/Shutdown switch for Raspberry Pi

	#!/usr/bin/env python2.7
	# This script is meant to be used to monitor a button on the
	# Raspberry Pi. I connected the button between pins 13 and 14,
	# chosen because BCM 27 is not used for anything else and it is
	# right next to a ground, so I can use a single connector.
	#
	# If the button is pressed breifly (less than 5 seconds), the Pi
	# will reboot. If the button is held down longer, it will shut down (halt).
	# After a halt, you will need to cycle power to restart.
