An anonymous reader quotes Bloomberg. [Alternate version here]:
During her 10-year career, she’s released more than 100,000 songs in a variety of languages and opened shows for Lady Gaga. And yet Hatsune Miku, who boasts 2.5 million Facebook followers, doesn’t actually exist — at least not in the typical way we think of a flesh-and-blood diva. Miku is a computer-simulated pop star created more than a decade ago by Hiroyuki Ito, CEO of Crypton Future Media in Sapporo, Japan.

She started life as a piece of voice-synthesis software but since has evolved to become a singing sensation in her own right — thanks to the creativity of her legions of fans. Crucial to Miku’s success is the ability for devotees to purchase the Yamaha-powered Vocaloid software and write their own songs for the star to sing right back at them. Fans then can upload songs to the web and vie for the honor of having her perform them at “live” gigs, in which the computer-animated Miku takes center stage, surrounded by human guitarists, drummers and pianists.

Bloomberg’s article includes some video clips of the virtual artist — as well as her real-world fans.

“In the absence of physical evidence, scientists are employing powerful computational tools to attempt to solve the greatest aviation mystery of our time: the disappearance of flight MH370.” Slashdot reader Esther Schindler shared this article from HPE Insights:
Satellite communications provider Inmarsat announced it had found recorded signals in its archives that MH370 had sent for another six hours after it disappeared. The plane had been aloft and flying for that whole time — but where had it gone? As Inmarsat scientists examined the signals, they saw that what they had was not data such as text messages or location information. Rather, the signals contained metadata: information about the signal itself. This was recorded as the satellite automatically contacted the plane’s communications system every hour to see if it was still logged on. Bafflingly, whoever had taken the plane hadn’t used the satcom system to communicate with the outside world, but had switched it off and then on again, leaving it able to exchange hourly “pings” with the satellite. Some of the metadata related to extremely subtle variations in the frequency of the signal. “We’re talking about changes as big as one part in a billion,” says Inmarsat scientist Chris Ashton.
Nobody had tried to use this kind of data to try to locate an airplane before. At first, Ashton’s team didn’t know if the attempt would work. But painstakingly, over the course of weeks, the team figured out how the movement of the plane, the orbital wobble of the satellite, and the electronics within the satcom system all interacted to create the data values that had been received. “We had to create the model from scratch,” Ashton says. Their work revealed that the plane had flown into the remote southern Indian Ocean. They didn’t know where exactly. But since there are no islands in that part of the world, it was impossible that anyone could have survived. For the first time in history, hundreds of people were declared legally dead based on mathematics alone.

Then mathematician Dr. Neil Gordon led a team from the Defense Science and Technology Group “to extract a path from a subset of the Inmarsat data called the Burst Timing Offset. This measured how quickly the aircraft responded each time the satellite pinged it, and was used to determine the distance between the satellite and the plane.” They ultimately generate “a probabilistic ‘heat map’ of the plane’s most likely resting places using a technique called Bayesian analysis. These calculations allowed the DSTG team to draw a box 400 miles long and 70 miles across, which contained about 90 percent of the total probability distribution.

An anonymous reader quotes Bleeping Computer: Scientists from Florida International University and Bloomberg have created a custom two-factor authentication (2FA) system that relies on users taking a photo of a personal object. The act of taking the photo comes to replace the cumbersome process of using crypto-based hardware security keys (e.g., YubiKey devices) or entering verification codes received via SMS or voice call. The new system is named Pixie, and researchers argue it is more secure than the aforementioned solutions. Pixie works by requiring users to choose an object as their 2FA key. When they set up the Pixie 2FA protection, they take an initial photo of the object that will be used for reference. Every time users try to log into their account again, they re-take a photo of the same object, and an app installed on their phone compares the two photos… In automated tests, Pixie achieved a false accept rate below 0.09% in a brute force attack with 14.3 million authentication attempts. An Android app is available for testing here.

An anonymous reader quotes the Press Democrat:
When deadly flames incinerated hundreds of homes in Santa Rosa’s Fountaingrove neighborhood earlier this month, they also destroyed irreplaceable papers and correspondence held nearby and once belonging to the founders of Silicon Valley’s first technology company, Hewlett-Packard. The Tubbs fire consumed the collected archives of William Hewlett and David Packard, the tech pioneers who in 1938 formed an electronics company in a Palo Alto garage with $538 in cash. More than 100 boxes of the two men’s writings, correspondence, speeches and other items were contained in one of two modular buildings that burned to the ground at the Fountaingrove headquarters of Keysight Technologies. Keysight, the world’s largest electronics measurement company, traces its roots to HP and acquired the archives in 2014 when its business was split from Agilent Technologies — itself an HP spinoff.
The Hewlett and Packard collections had been appraised in 2005 at nearly $2 million and were part of a wider company archive valued at $3.3 million. However, those acquainted with the archives and the pioneering company’s impact on the technology world said the losses can’t be represented by a dollar figure… Karen Lewis, the former HP staff archivist who first assembled the collections, called it irresponsible to put them in a building without proper protection. Both Hewlett-Packard and Agilent earlier had housed the archives within special vaults inside permanent facilities, complete with foam fire retardant and other safeguards, she said. “This could easily have been prevented, and it’s a huge loss,” Lewis said.
Lewis has described the collection as “the history of Silicon Valley … This is the history of the electronics industry.” Keysight Technologies spokesman Jeff Weber said the company “is saddened by the loss of documents that remind us of our visionary founders, rich history and lineage to the original Silicon Valley startup.”

23 Californians were killed in the fires, which also destroyed 6,800 homes, and Weber says Keysight had taken “appropriate and responsible” steps to protect the archive, but “the most destructive firestorm in state history prevented efforts to protect portions of the collection.”
