False White House explosion tweet rattles market
A fake tweet from the account of the Associated Press sent stocks tumbling more than 140 points within minutes, erasing all of the day's gains and then some, before bouncing back just as rapidly. The erroneous tweet, which was posted around 1:07 p.m. ET, said "BREAKING: Two Explosions in the White House and Barack Obama is injured." The tweet was up for a few minutes before AP's account was suspended, and presumably seen by many of AP's nearly 2 million followers. The tweet was also retweeted by almost 1,500 other Twitter users.
Delays stack up in airports: Start the blame game
How much frustration will build up in the skies before politicians on the ground in Washington do something about flight delays? That's what the flying public, airlines and some politicians asked Tuesday, as delays erupted across the nation's air-traffic grid for the second straight weekday that air-traffic controllers were taking a day off without pay. The battle over automatic federal spending cuts - resulting in the furlough of about 1,500 controllers a day - combined with weather and airport construction caused 273 cancellations and 4,749 delayed flights by late in the day, according to FlightAware.com, which tracks U.S. flights.
Nike pulls "Boston Massacre" shirts following bombings
Nike has pulled shirts that read "Boston Massacre" -- a reference to the Yankees-Red Sox rivalry -- from store shelves in light of the tragedy in Boston last week. The phrase references a four-game sweep of the Red Sox by the Yankees in 1978 that was part of an epic late-season collapse for Boston. The T-shirts in question were printed in Yankee colors, with drops of blood splattered over the lettering. Following the fatal attacks in Boston, Nike (NKE Fortune 500 "took immediate action last week to remove this product from distribution," company spokesman Brian Strong said in an email.
How Facebook Home is doing
Facebook Home, the social-media site's attempt to put itself more at the center of people's digital lives, has been downloaded more than 500,000 (but less than a million) times after being released nearly two weeks ago. That either sounds like a lot or not very many at all, depending on your perspective. It's an essentially opaque number -- or at best, a datapoint that is meaningless without context. Facebook Home is a layer that lies on top of the Android operating system. It's not an app, and it's not an OS. Wired has decided to give it the unfortunate descriptor "apperating system."
