There's just one problem: Tesla's new battery doesn't work well with rooftop solar—at least not yet. Even Solar City, the supplier led by Musk, isn't ready to offer Tesla's battery for daily use.
A centimeter-accurate GPS-based positioning system that could revolutionize geolocation on virtual reality headsets, cellphones, and other devices has been developed by researchers in the Cockrell School of Engineering at The University of Texas at Austin.
Fifty years after Gordon Moore first described the trend that has driven technology, Intel says scaling is same as it ever was. But other chipmakers, who are struggling to realize the same benefits from good old-fashioned scaling, are increasingly looking for less-expensive alternatives.
When the last version of the Hypertext Transfer Protocol 1.1 (HTTP/1.1) was approved in 1999, fast computers were running 500MHz Pentium III chips, Bill Clinton was president of the United States, and software engineers were working hard at fixing the Y2K bug.
