Linux "The London Stock Exchange has said its new Linux-based system is delivering world record networking speed, with 126 microsecond trading times. The news comes ahead a major Linux-based switchover in twelve days, during which the open source system will replace Microsoft .Net technology on the group’s main stock exchange. The LSE had long been criticised on speed and reliability, grappling with trading speeds of several hundred microseconds. The record breaking times were measured on the LSE’s Turquoise smaller dark pool trading venue, where trades are conducted anonymously. That network switched over to Linux from Cinnober technology two weeks ago. Speed is crucial as more firms trade automatically at lightning speed, using advanced algorithms."

Day trading may be more akin to gambling (it is almost a zero-sum game, after all), but legitimate investing on the stock market is not. Historically, the market has increased in value by an average of 10% year-on-year. If it's gambling, it'd be like playing a game where E[X]=X*1.1 - good odds, by any measure. And an educated investor can beat the market without too much difficulty. Of course there is risk; there wouldn't be profit otherwise.
