Vanity performance metrics — Looking beyond the numbers

Vanity performance metrics — Looking beyond the numbers

My deck from RuhrJS in Germany—Slide notes, references and Shoutouts to those who shared so much great and interesting data about global internet connectivity are missing! I'll attempt to update the deck in a couple of days after jetlag stops hurting me so much :-)

Shout out to Bruce Lawson for being such a thoughtful and clever person.

  33. “I read a study that measured the efficiency of locomotion

    for various species on the planet. The condor used the least energy to move a kilometre. Humans came in with a rather unimpressive showing about a third of the way down the list....That didn't look so good, but then someone at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle and a man on a bicycle blew the condor away. That's what a computer is to me: the computer is the most remarkable tool that we've ever come up with. It's the equivalent of a bicycle for our minds.”
