On Sunday afternoon, Virgin Orbit joined the rare club of companies that have privately developed a rocket and successfully launched it into orbit. Moreover, with its LauncherOne rocket dropped from a 747 aircraft, the California-based company has become the first to reach orbit with an air-launched, liquid-fueled rocket.

"This magnificent flight is the culmination of many years of hard work and will also unleash a whole new generation of innovators on the path to orbit," said Sir Richard Branson, the founder of the company. "Virgin Orbit has achieved something many thought impossible."

Sunday's flight, which included multiple firings of LauncherOne's upper stage engine and successful deployment of several small satellites for NASA, caps a development program that has spanned about eight years and myriad technical challenges.

Apple pulls the plug on user-found method to sideload iOS apps on Mac

The Mac App Store—the only place you can easily get iOS and iPadOS apps for Mac.

Enlarge / The Mac App Store—the only place you can easily get iOS and iPadOS apps for Mac.

Apple has plugged a hole that allowed users to sideload iOS and iPad applications to M1 Macs that were never intended to run on desktop, 9to5Mac reports. The server-side change ensures that only applications that app developers have flagged as optimized for Mac will run.

Late last year, Apple launched its first Macs running on its own ARM-based custom CPU called the M1, as opposed to the Intel chips that have been used in Macs for several years. These new machines included the entry-level 13-inch MacBook Pro, the MacBook Air, and the low-end Mac mini.

Since those machines now share an architecture with iPhones and iPads, which also have closely related ARM-based chips, it became possible to run iOS and iPadOS apps natively on Macs that were equipped with the M1 chip. Apple supported this by listing iPhone and iPad apps that passed an automated test on the Mac App Store, provided developers did not opt out of having the app listed.

Samsung’s top executive gets 30 months in prison for bribery

It's back to jail for Samsung's leader, Lee Jae-yong (aka Jay Y. Lee). Lee has been embroiled in a legal battle for his role in "Choigate," a major 2016 South Korean political scandal that led to South Korean President Park Geun-hye being impeached and removed from office. The scandal is named for the president's top aid, Choi Soon-sil, a member of a shamanistic cult that was found to be masterminding South Korean government policy via her influence over the president. It's a long story, but Choi was sentenced to 20 years in prison for influence peddling, and Park was sentenced to 25 years.

Samsung's part in this mess involves accusations that Lee bribed Choi for favorable rulings related to the merger of two Samsung affiliates. In 2017, Lee was sentenced to five years in jail after being found guilty of bribery, embezzlement, capital flight, and perjury charges. Six months after his sentencing, an appeals court cut Lee's sentence in half and suspended the charges for bribery and embezzlement. Lee was released from prison while the appeals process continued. The case wound its way all the way up to the South Korean Supreme Court, which, in 2019, ordered a retrial.

Today's ruling sentences Lee to 30 months in prison, and after having already served one year, Samsung's leader should be spending the next year and a half behind bars.

Toyota wants to win Le Mans with its new GR010 hybrid prototype

ArsTechnica - Mon, 01/18/2021 - 9:50am

The future of the 24 Hours of Le Mans is resolving into shape. On Friday, Toyota Gazoo Racing unveiled its new GR010 Hybrid, an all-wheel drive prototype that will compete in the overall win at the annual French race later this year (pandemic willing). It's the first competitor to break cover from the new Le Mans Hypercar (LMH) class, which replaces the old LMP1h category that shone so brightly for a few short years in the middle of the last decade.

LMP1h gave rise to some of the fastest and most technologically advanced racing cars the world has ever seen. But it wasn't cheap, and by 2018 Toyota was all that was left, its cars hobbled by ACO (the race organizers) to give the non-hybrid LMP1 privateer teams a fighting chance.

Car manufacturer interest in racing series waxes and wanes, and it doesn't require much imagination to see how a combination of global economic uncertainty and an expensive ruleset could negatively impact participation. The ACO's answer was a new category called the hypercar, which would open the doors to racing versions of those seven-figure slices of unobtainium-on-wheels like the Adrian Newey-designed Aston Martin Valkyrie—albeit running at much lower power levels than the unrestricted road cars.

Lunar war brews and NASA gets militarized in For All Mankind S2 trailer

ArsTechnica - Sun, 01/17/2021 - 6:23pm

The space race in an alternate timeline continues in the second season of For All Mankind, returning to Apple TV+ in February.

Apple TV+ has dropped the trailer for the second season of For All Mankind, its science fiction drama about an alternate history where the space race never ended. The series was the linchpin of the Apple TV+ launch in 2019 and proved popular enough with viewers to warrant a second season.

(Some spoilers for the first season below.)

Series creator Ronald D. Moore (Battlestar Galactica) has made a point of trying to keep the show reasonably close to reality, despite the science fiction concept, often consulting the original NASA plans for guidance and incorporating archival footage throughout the season. Moore said the following during a 2019 panel Q&A after an IMAX screening of the first two S1 episodes at the National Air and Space Museum in Washington, DC:

Review: Chilling Adventures of Sabrina ends run with disappointing finale

ArsTechnica - Sun, 01/17/2021 - 1:01pm

Our favorite half-human/half-witch teenager took on eight timeless menacing entities to avert the apocalypse (again) in the final season of The Chilling Adventures of Sabrina. I've championed this weirdly captivating supernatural horror show from the beginning, and for three seasons the strengths have always outshone the occasional weakness. Unfortunately, S4 turned out to be the weakest of all, despite including one of the best episodes of the entire Netflix series and what should have been a strong, unifying narrative arc. It's still pretty entertaining, but there was just a little too much pointless fan service and sloppy plotting this time around for S4 to really work.

(Spoilers for prior seasons below. Major spoilers for the series finale are below the second gallery. We'll give you a heads up before we get there.)

As we've reported previously, the show was originally intended as a companion series to the CW's Riverdale—a gleefully Gothic take on the original Archie comic books—but Sabrina ended up on Netflix instead. The show retains some of the primetime soap opera elements of Riverdale, but it incorporates more full-blown horror without bowing to the niceties imposed by network television. As I wrote last year, "Ultimately, the best thing about The Chilling Adventures of Sabrina is how gleefully and unapologetically the show leans into its melting pot of the macabre. It's quite the high-wire act, exploring serious themes while never, ever taking itself too seriously—and never descending into outright camp."

One of the quietest revolutions of our current century has been the entry of quantum mechanics into our everyday technology. It used to be that quantum effects were confined to physics laboratories and delicate experiments. But modern technology increasingly relies on quantum mechanics for its basic operation, and the importance of quantum effects will only grow in the decades to come. As such, physicist Miguel F. Morales has taken on the herculean task of explaining quantum mechanics to the rest of us laymen in this seven-part series (no math, we promise). Below is the second story in the series, but you can always find the starting story here.

Welcome back for our second guided walk into the quantum mechanical woods! Last week, we saw how particles move like waves and hit like particles and how a single particle takes multiple paths. While surprising, this is a well-explored area of quantum mechanics—it is on the paved nature path around the visitor’s center.

This week I’d like to get off the paved trail and go a bit deeper into the woods in order to talk about how particles meld and combine while in motion. This is a topic that is usually reserved for physics majors; it's rarely discussed in popular articles. But the payoff is understanding how precision lidar works and getting to see one of the great inventions making it out of the lab, the optical comb. So let's go get our (quantum) hiking boots a little dirty—it'll be worth it.

AI-powered text from this program could fool the government

AI-powered text from this program could fool the government

Enlarge (credit: Elena Lacey | Getty Images)

In October 2019, Idaho proposed changing its Medicaid program. The state needed approval from the federal government, which solicited public feedback via Medicaid.gov.

Roughly 1,000 comments arrived. But half came not from concerned citizens or even Internet trolls. They were generated by artificial intelligence. And a study found that people could not distinguish the real comments from the fake ones.

The project was the work of Max Weiss, a tech-savvy medical student at Harvard, but it received little attention at the time. Now, with AI language systems advancing rapidly, some say the government and Internet companies need to rethink how they solicit and screen feedback to guard against deepfake text manipulation and other AI-powered interference.

After a decade, NASA’s big rocket fails its first real test

ArsTechnica - Sat, 01/16/2021 - 8:57pm

STENNIS SPACE CENTER, Miss. — For a few moments, it seemed like the Space Launch System saga might have a happy ending. Beneath brilliant blue skies late on Saturday afternoon, NASA’s huge rocket roared to life for the very first time. As its four engines lit and thrummed, thunder rumbled across these Mississippi lowlands. A giant, beautiful plume of white exhaust billowed away from the test stand.

It was all pretty damn glorious until it stopped suddenly.

About 50 seconds into what was supposed to be an 8-minute test firing, the flight control center called out, “We did get an MCF on Engine 4.” This means there was a “major component failure” with the fourth engine on the vehicle. After a total of about 67 seconds, the hot fire test ended.
