People's Facebook posts might predict whether they are suffering from depression, researchers reported this week. From a report: The researchers found that the words people used seemed to indicate whether they would later be diagnosed with depression. The findings offer a way to flag people who may be in need of help, but they also raise important questions about people's health privacy, the team reported in the Proceedings of the National Academy of Sciences. People who were later clinically diagnosed with depression used more "I" language, according to Johannes Eichstaedt of the University of Pennsylvania and his colleagues. They also used more words reflecting loneliness, sadness and hostility. "We observed that users who ultimately had a diagnosis of depression used more first-person singular pronouns, suggesting a preoccupation with the self," they wrote. That is an indicator of depression in some people. The team recruited 683 people who visited an emergency room for their study and asked to see their Facebook pages. Most were not depressed, but 114 had a depression diagnosis in their medical records.

In the early days of what ultimately became Waymo, Google's self-driving car division (known at the time as "Project Chauffeur"), there were "more than a dozen accidents, at least three of which were serious," according to a new article in The New Yorker . From a report: The magazine profiled Anthony Levandowski, the former Google engineer who was at the center of the Waymo v. Uber trade secrets lawsuit. According to the article, back in 2011, Levandowski also modified the autonomous software to take the prototype Priuses on "otherwise forbidden routes." Citing an anonymous source, The New Yorker reports that Levandowski sat behind the wheel as the safety driver, along with Isaac Taylor, a Google executive. But while they were in the car, the Prius "accidentally boxed in another vehicle," a Camry. As The New Yorker wrote: "A human driver could easily have handled the situation by slowing down and letting the Camry merge into traffic, but Google's software wasn't prepared for this scenario. The cars continued speeding down the freeway side by side. The Camry's driver jerked his car onto the right shoulder. Then, apparently trying to avoid a guard rail, he veered to the left; the Camry pinwheeled across the freeway and into the median. Levandowski, who was acting as the safety driver, swerved hard to avoid colliding with the Camry, causing Taylor to injure his spine so severely that he eventually required multiple surgeries." This was apparently just one of several accidents in Project Chauffeur's early days.

I just posted a tech note for Rainier’s scripting language, Ballard.

Feedback is welcome, of course. Best place is on the Slack group. (You can find my email address near the bottom of this page and then email me to ask for an invitation.)

Saudi Crown Prince Mohammed Bin Salman comes under scrutiny as investigators find more clues.

Millions of dollars in funding and billions of dollars in valuations have made scooters the next big thing since the last big thing. From a report: When Michael Ramsey, an analyst for technology research firm Gartner, started in February to put together his 2018 "hype cycle" report for the future of transportation, he had plenty of topics to choose from: electric vehicles, flying cars, 5G, blockchain, and, of course, autonomous vehicles. But one type of transportation is conspicuously absent from the results of the report: electric scooters. "At the time, outside of California, these scooters were really not that common," Ramsey said. "That's how much has happened." As for autonomous vehicles, which have enjoyed years of hype as the next big thing, Ramsey labeled them sliding into "the trough of disillusionment," which Ramsey described as "when expectations don't meet the truth." In a matter of months, electric scooter startups have gone from tech oddity to global phenomenon. In some cities, hundreds of scooters suddenly showed up on streets from companies including Bird and Lime, leaving municipalities to figure out how to handle the sudden influx of two-wheeled travelers. The concept behind the scooters is simple: A user can grab any available scooter, unlock it with an app, ride to their destination, and leave the scooter there for someone else to use. Even by the hyper-growth expectations of Silicon Valley, the rise of scooter companies has been dizzying. Scooters can be found in more than 125 cities in the U.S. and more than 10 across the globe. In the year after their launch, both Lime and Bird said their scooters had been used for more than 10 million rides.

A security researcher from Colombia has found a way of gaining admin rights and boot persistence on Windows PCs that's simple to execute and hard to stop -- all the features that hackers and malware authors are looking for from an exploitation technique. From a report: What's more surprising, is that the technique was first detailed way back in December 2017, but despite its numerous benefits and ease of exploitation, it has not received either media coverage nor has it been seen employed in malware campaigns. Discovered by Sebastian Castro, a security researcher for CSL, the technique targets one of the parameters of Windows user accounts known as the Relative Identifier (RID). The RID is a code added at the end of account security identifiers (SIDs) that describes that user's permissions group. There are several RIDs available, but the most common ones are 501 for the standard guest account, and 500 for admin accounts. Castro, with help from CSL CEO Pedro Garcia, discovered that by tinkering with registry keys that store information about each Windows account, he could modify the RID associated with a specific account and grant it a different RID, for another account group. The technique does not allow a hacker to remotely infect a computer unless that computer has been foolishly left exposed on the Internet without a password. But in cases where a hacker has a foothold on a system -- via either malware or by brute-forcing an account with a weak password -- the hacker can give admin permissions to a compromised low-level account, and gain a permanent backdoor with full SYSTEM access on a Windows PC.

Andrew Liszewski, writing for io9: Casting anyone other than Harrison Ford in the role of Han Solo just feels like sacrilege, but since Ford is now 76 years old, playing a younger version of himself would be all but impossible. Or at least impossible if you rely on the standard Hollywood de-aging tricks like makeup and CG. Artificial intelligence, it turns out, does a pretty amazing job at putting Ford back into the role of Solo. The YouTube channel "derpfakes" has been posting videos that demonstrate the impressive, and at times frightening, capabilities of image processing using artificial intelligence. Using a process called deep learning, an AI analyzes a large collection of photos of a given person, creating a comprehensive database of them in any almost any position and pose. It then uses that database to intelligently perform an automatic face replacement on a source clip, in this case replacing actor Alden Ehrenreich's face with Harrison Ford's.
