Smartphone cameras get smarter

Get ready for sharper selfies, said Youkyung Lee in the Associated Press. Following similar moves by Sony and Nokia, Samsung announced that it has “beefed up the camera” in its Galaxy S5 smartphone, adding “smarter camera software” meant to greatly improve the quality of Samsung snapshots. Samsung and other manufacturers hope the upgraded cameras will bring smartphone photos “closer in quality to images captured by digital single-lens reflex cameras.” That has long been a big technological challenge in a market that has been focused on selling ever-thinner phones. Now “the gap is getting narrower thanks mainly to improvements in camera software and other technologies.”

Apple fixes security flaw

Users of Macs, iPhones, and iPads should take a minute to update their software, said Molly Wood in NYTimes.com. Apple last week issued a security update to its OS X Mavericks operating system for Macs, “patching a bug that could have let hackers eavesdrop on supposedly encrypted connections and steal everything from usernames and passwords to location data.” The update, labeled 10.9.2, was posted just four days after Apple issued an iOS update “to close the same hole” on its mobile devices. “The flaw is extremely serious,” making it impossible for your device to validate a certificate that claims, for instance, that you’re on your bank’s website. Apple users “who haven’t yet updated their OS should do so immediately.”
