Worth Reading: How Big Data Creates False Confidence

It’s tempting to think that with such an incredible volume of data behind them, studies relying on big data couldn’t be wrong. But the bigness of the data can imbue the results with a false sense of certainty. Many of them are probably bogus—and the reasons why should give us pause about any research that blindly trusts big data. -via Nautilus

Lenovo software has a major security risk

Just as the dust has settled on the Superfish controversy, another piece of software installed on Lenovo PCs is causing problems. This time it's due to a major malware exploit.The problem is with Lenovo Solution Center (LSC) software, which the company describes as "a central hub for monitoring system health and security." LSC is supposed to monitor your system's virus and firewall status, update your software, perform backups, check battery health, and get registration and warranty information.Unfortunately, it also has a vulnerability that allows a malicious attacker to start the LSC service and trick it in to executing arbitrary code in the local system context, according to researchers at Trustwave SpiderLabs.To read this article in full or to leave a comment, please click here

How news was delivered aboard a cruise ship in 1998

Housecleaning yesterday unearthed this miniature 8-page publication called TimesFax, which was delivered to me by the New York Times aboard a cruise ship somewhere in the Caribbean on May 23, 1998. Measuring 7 by 8.5 inches, it was, as I recall, the only source of news available, and since it lacked a full-service sports section, meant I had to go without the box scores needed to follow my fantasy baseball team (unthinkable today). Such were the limitations of leisure travel in that primitive era, at least the manner of leisure travel that I could afford. While the form factor and delivery method were unusual by today’s standards, the headlines were certainly familiar, as the front page featured accounts of both a school shooting and a Clinton scandal, the latter involving the former president as opposed to the future one, of course. That skimpy sports section did include an Associated Press story about the Williams sisters, Serena and Venus, meeting in the final of the French Open, marking the first time they had ever met in the final of a professional tournament.To read this article in full or to leave a comment, please click here
