What We Know About the Computer Formulas Making Decisions in Your Life

propublica.org — We reported yesterday on a study of Uber's dynamic pricing scheme that investigated Uber's surge pricing patterns in Manhattan and San Francisco and showed riders how they could potentially avoid higher prices. The study's authors finally shed some light on Uber's "black box," the algorithm that automatically sets prices but that is inaccessible to both drivers and riders.

Uber’s Surge Pricing May Not Lead to a Surge in Drivers

gizmodo.com — Uber has long stirred controversy and consternation over the higher "surge" prices it charges at peak times. The company has always said the higher prices actually help passengers by encouraging more drivers to get on the road. But computer scientists from Northeastern University have found that higher prices don't necessarily result in more drivers.

Your Smart Home Knows a Lot About You

propublica.org — How much does your smart home know about you? That was the question that Charles Givre, a data scientist at Booz Allen Hamilton, set out to answer in a recent experiment. Givre has an account on Wink, a platform designed to control, from a single screen, his Internet-connected home devices, such as door locks, window shades and LED lights.

propublica.org — A recent ProPublica analysis of The Princeton Review's prices for online SAT tutoring shows that customers in areas with a high density of Asian residents are often charged more. When presented with this finding, The Princeton Review called it an "incidental" result of its geographic pricing scheme.

The Best Defense Is Good Offense: DOJ Challenges Local Public Defense Programs

propublica.org — Shortly before Attorney General Eric Holder announced his resignation last September, he told an interviewer: "Any attorney general who is not an activist is not doing his or her job." One of Holder's more activist initiatives received attention last week when The New York Times highlighted how Holder's Justice Department began the novel practice of filing arguments in state and county courts.

America’s water crisis is so much bigger than California

salon.com — This article was originally published by Scientific American. Why do I keep hearing about the California drought, if it's the Colorado River that we're "killing"? Pretty much every state west of the Rockies has been facing a water shortage of one kind or another in recent years.
