Calculating the median distance and time of NYC taxi rides in 2013

	// transcribed from an Apache Spark 1.0 spark-shell session
	// using data from http://chriswhong.com/open-data/foil_nyc_taxi/
	// and the QTree algorithm for approximate quantiles over large datasets
	// each of the distanceRange and minutesRange calculations below takes about 15 minutes on my four-core SSD-based Macbook Pro

Check the mayday.us total once every 60 seconds and print stats.

ruby -rjson -ropen-uri -e 'last = - 1; while true; dollars=(JSON.parse(open("https://pledge.mayday.us/r/total").read)["totalCents"] - 100000000)/100; puts "$#{dollars} raised. $#{5000000-dollars} to go.#{last == -1 ? "" : " #{sprintf("%6s", "$"+(dollars-last).to_s)} in the last 60 seconds. #{"*" * ((dollars-last)/250.0).round}"}"; last = dollars;  sleep 60 ; end'
