	# Config for Nginx to act as a front-end for Riak
	# The main goal is to proxy all GETs directly to Riak, and disallow anything else (POST, PUT, etc)
	# Also, disallow use of the map/reduce query links (i.e. /riak/bucket/key/_,_,_)

	# Config is in /etc/nginx/sites-available/default or somewhere like that

	# Set up load-balancing to send requests to all nodes in the Riak cluster
	# Replace these IPs/ports with the locations of your Riak nodes

Solve a puzzle posed on NPR (see: http://www.npr.org/2012/01/29/146034893/this-puzzle-is-the-pits - "Next Week" section )

	(* Inspired by this puzzle from NPR:
	http://www.npr.org/2012/01/29/146034893/this-puzzle-is-the-pits
	(see the 'Next Weeks' challenge section there):
	"Next Week's Challenge from listener Ed Pegg Jr.: Write the digits from
	1 to 9 in a line. If you put times signs after the 2 and 4, a plus
	sign after the 5, and a minus sign after the 7, you have
	12 x 34 x 5 + 67 - 89, which equals 2018.
	That's six years off from our current year 2012. This example uses
	four arithmetic symbols. The object is to use just three of the
	following arithmetic operations: addition, subtraction, multiplication
