WALL STREET-TWITTER TUMBLE NEW YORK â¿¿ For decades, computers have been helping people sort through data and news to decide whether to buy or sell stocks. Now the machines seem to have dispensed with the slowpoke humans. Just how big a role computers played in Tuesday's brief market swoon is uncertain. But, according to some experts, when human traders read a fake news tweet and hesitated to buy, the computers took over and went into sell mode.

FOOD-GAS DRILLERS' DELIGHTS PENNSDALE, Pa. â¿¿ The land of scrapple and chipped ham is starting to get a taste for jambalaya and boudin. Thanks to an influx of Southerners filling jobs in north-central Pennsylvania's booming natural gas industry, a region not often placed on many culinary maps is finding itself flush with the foodways found below the Mason-Dixon line, arguably the source of some of the nation's richest culinary traditions. Suddenly, convenience stores stock sweet tea, barbecue is a hot seller, and the almost Norman Rockwell-quaint Country Store in Pennsdale even makes its own boudin, a pork sausage popular in Louisiana.
