Anonymous no more
IF YOUR face and name are anywhere on the web, you may be recognised whenever you walk the streets—not just by cops but by any geek with a computer. That seems to be the conclusion from some new research on the limits of privacy. For suspected miscreants, and people chasing them, face-recognition technology is old hat. Brazil, preparing for the soccer World Cup in 2014, is already trying out pairs
The end of Wintel
THEY were the Macbeths of information technology (IT): a wicked couple who seized power and abused it in bloody and avaricious ways. Or so critics of Microsoft and Intel used to say, citing the two firms' supposed love of monopoly profits and dead rivals. But in recent years, the story has changed.

TWO centuries after Gutenberg invented movable type in the mid-1400s there were plenty of books around, but they were expensive and poorly made. In Britain a cartel had a lock on classic works such as Shakespeare's and Milton's. The first copyright law, enacted in the early 1700s in the Bard's home country, was designed to free knowledge by putting books in the public domain after a short period o

Merger interruptus
Merger interruptusRegulators may block a big technology tie-up, but their case is not convincing FOR a brief period many hoped that trustbusters in Europe and America would start playing in tune. During the eight years of the Bush administration, the European Commission's competition police took a notably more activist approach than their American counterparts.

古川 享 on Twitter: "実は告白すると過去30年間、私は技術系の会社から出ている技術発表資料をいつも読みあさっていた。それらはお宝の山で「未来はこうなる」と私が発言する時の元ネタに。http://bit.ly/bfYzpE 雑誌や新聞に出ている記事を追いかけていても、その先の時代は読めないよ！"
