According to NASA officials, both “advanced air mobility” and “national campaign” better reflect the goals of the undertaking, which is planned as a series of field demonstrations to evaluate the readiness of new types of aircraft and airspace management systems. The demonstrations will progress in stages to encompass a full range of scenarios under varying weather and traffic conditions — including, but not limited to, scaled urban air taxi operations.
“We’ve talked mostly over the past couple of years about ‘urban air mobility,’” said NASA AAM mission manager Davis Hackenberg in the web conference that served as a virtual kick-off for the agency’s AAM Ecosystem Working Groups (a substitute for an in-person event that was canceled due to coronavirus concerns). “We’d always intended to include other types of [mobility], whether that was rural or urban, but the name I think was getting in the way a little bit.” …
Big phone launches come thick and fast towards the end of each year. And 2019 has been no different. Pretty much the last manufacturer to reveal its flagship devices every year is Google – the Pixel 4 has now arrived.
It’s Google’s fourth in-house phone and, as evolutions go, there are a few potential upgrades. There’s an extra camera, a new radar-based gesture system and Google has killed the notch. But do they add to the phone? …
Facebook doesn’t want its hardware like Oculus or its augmented reality glasses to be at the mercy of Google because they rely on its Android operating system. That’s why Facebook has tasked Mark Lucovsky, a co-author of Microsoft’s Windows NT, with building the social network an operating system from scratch, according to The Information’s Alex Heath. To be clear, Facebook’s smartphone apps will remain available on Android.
“We really want to make sure the next generation has space for us,” says Facebook’s VP of Hardware, Andrew ‘Boz’ Bosworth. “We don’t think we can trust the marketplace or competitors to ensure that’s the case. And so we’re gonna do it ourselves.” …
Global test finds those using two-thumb technique can hit a blistering 38 words per minute
Think of it as an upside to spending hours on a smartphone. Thanks to all that dextrous thumb work, people can now type nearly as fast on a screen as they can on a keyboard.
Researchers made the discovery during a study of typing skills in which more than 37,000 volunteers from 160 countries took a speed and accuracy test on their mobile phones.
People who tapped out messages with a single finger managed on average only 29 words per minute (wpm), but those who mastered the two-thumb technique hit a blistering 38wpm, only 25% slower than an average typer on a full-sized Qwerty keyboard.
“We recently discovered that a Chrome update may have shipped with a bug that damages the file system on MacOS machines,” the company wrote in a forum post. “We’ve paused the release while we finalize a new update that addresses the problem.”
Reports of Mac Pro workstations refusing to reboot started to circulate among video editors late Monday. At the time, the common denominator among impacted machines seemed to be the presence of Avid’s Media Composer software…
Amazon’s September hardware event returned this year to bring us spanking-new devices, with Alexa-enabled features front and center, shocking. The event, which Amazon live-blogged but did not stream, kicked off as it did last year with a presentation from David Limp, Amazon’s senior vice president of devices. He teased out some of what’s new from the company and just like last year, Amazon dropped so many product reveals that it’ll make your head spin. Here’s what to know.
First up, Amazon’s Echo Dot gets a clock. According to CNET, the new Echo Dot with Clock has an LED screen behind the speaker that will display not only the time but alarm times and the temperature when asked. This little guy clocks in (sorry) at $60 and is available for pre-order beginning today. Amazon says if the Dot is used as an alarm clock, users can now tap to snooze as well…

Last week, the Daily Beast reported that Stallman had also called for the legalization of child pornography and abolishment of age of consent laws on his personal blog in multiple posts published over the course of 15 years.
In his MIT CSAIL resignation, also posted to his personal blog, Stallman wrote: “To the MIT Community, I am resigning effective immediately from my position in CSAIL at MIT. I am doing this due to pressure on MIT and me over a series of misunderstandings.”
MIT has been under scrutiny for its ties to Epstein, whom a New Yorker investigation found had secured $7.5 million in donations for the MIT Media Lab, far more than what was previously disclosed. As a result, its director, Joi Ito, resigned last week and MIT ordered an investigation into the Media Lab’s ties to Epstein, who was found dead in his jail cell last month while awaiting federal trial on sex trafficking charges…
