Maps and legends

This chart, which I found flipping through Stern magazine in Germany, accomplishes one important goal. It makes me stop flipping, and look. The chart presents a point of view that is refreshing. The Airbus A320 is a true collaborative effort....

Would you be willing to miss a train to admire art?

This wonderful data visualization made me stop in my tracks at a train station somewhere in Bavaria. It conveys so much information in such an efficient manner. At a glance, the diagram tells passengers the configuration of the train they...

scale acceleration

Kate Lee pointed me to a rather surprising inefficiency in matlab, exploited in Sylvia Früwirth-Schnatter’s bayesf package: running a gamma simulation by rgamma(n,a,b) takes longer and sometimes much longer than rgamma(n,a,1)/b, the latter taking advantage of the scale nature of b. I wanted to check on my own whether or not R faced the same […]

March 19, 2015
By

Only 6% of crashes in New Zealand involve foreign drivers, according to the latest figures provided by the Ministry of Transport. But in some remote regions of the South Island particularly popular with tourists for their scenery... foreign drivers are involved in about a quarter of all crashes. These sentences come from a CNN article about a vigilante movement in those regions popular with tourists. The vigilantes snatch car keys…
