A Canadian court has ruled that the extradition hearing of Meng Wanzhou can continue.
YouTube says it has "rolled out a fix" for an "error in our enforcement systems" that had led to the automatic deletion of comments that included two phrases critical of China's government. But in an email exchange and phone call with Ars Technica, a company spokeswoman declined to provide real details about why YouTube's software was deleting the comments in the first place.
As I explained on Tuesday, "共匪" means "communist bandit." It was a derogatory term used by Nationalists during the Chinese Civil War that ended in 1949. It continues to be used by Chinese-speaking critics of the Beijing regime, including in Taiwan.
"五毛" means "50-cent party." It's a derogatory term for people who are paid by the Chinese government to participate in online discussions and promote official Communist Party positions. In the early years of China's censored Internet, such commenters were allegedly paid 50 cents (in China's currency, the yuan) per post.
More than 100,000 people in the United States have died from COVID-19 according to several pandemic-tracking efforts—and the pandemic is far from over. As the country reached the grim milestone, many areas were still seeing increasing case counts, and researchers have suggested that a second wave of infection is looming.
The risk of continued spread remains high as all 50 states have now begun easing restrictions aimed at curbing transmission.
So far, the US leads the world in the number of confirmed cases and deaths, with around 1.7 million cases and over 100,000 deaths. The country with the next highest numbers is Brazil, which has nearly 400,000 cases and over 24,500 deaths.
SpaceX and OneWeb have asked for US permission to launch tens of thousands of additional satellites into low Earth orbit.
OneWeb's application to launch nearly 48,000 satellites is surprising because the satellite-broadband company filed for bankruptcy in March. OneWeb is highly unlikely to launch a significant percentage of these satellites under its current structure, as the company reportedly "axed most of its staff" when it filed for bankruptcy and says it intends to use bankruptcy proceedings "to pursue a sale of its business in order to maximize the value of the company." Getting FCC approval to launch more satellites could improve the value of OneWeb's assets and give more options to whoever buys the company.

President Donald Trump threw efforts to renew a controversial Patriot Act provision into turmoil on Tuesday evening with a tweet calling on Republican members of the House to reject spying legislation that is due for a vote this week. It's the latest setback for a bill that has been embroiled in controversy for months.
The provision, known as Section 215, was first passed in the wake of the September 11 terrorist attacks. It gives the federal government broad powers to obtain "any tangible thing," including "books, records, papers, documents, and other items," without a warrant.
This power isn't supposed to be used for ordinary criminal cases—only for foreign intelligence operations. But it has been subject to abuse in the past. Most notoriously, Section 215 was used to collect records of every phone call made in America for several years. The NSA ultimately terminated the program under sustained pressure from civil liberties groups.

4:20pm ET Wednesday: SpaceX scrubbed the launch of its Falcon 9 rocket and Crew Dragon spacecraft Wednesday a little less than 17 minutes before liftoff. Although weather conditions were improving at the launch site—thunderstorms rolled through earlier in the day, and a tornado warning was issued for Kennedy Space Center—they did not improve fast enough. Had Dragon been able to launch 10 minutes later, the weather would have been good to go.
Informed of the scrub, Dragon's commander Doug Hurley said from inside the spacecraft, "It was a good effort by the teams, and we understand. Everybody’s probably a little bit bummed out. It’s just part of the deal."
There were no technical issues with Dragon or the rocket. Now SpaceX will work to recycle the systems for another launch attempt on Saturday at 3:22pm ET (19:22 UTC). The reason for skipping the next two days is an unfavorable phase angle for Dragon's approach to the International Space Station. Weather is forecast to be somewhat better on Saturday, but it is no slam-dunk. A back-up opportunity will be available on Sunday.
You know that scene in every forensic crime drama where someone works out the angle the bullet was fired from and points back to the source? In the case of the Chicxulub asteroid impact and the end-Cretaceous mass extinction 66 million years ago, there’s no mystery about the shooter. (Space did it.) But the trajectory is interesting for other reasons, and researchers have long been trying to trace the path back out of the crater off the Yucatán coast.
Unsurprisingly, 66 million years have taken their toll on the crater, so researchers have offered several very different answers. Did the asteroid hit from the southeast at a very low angle? Did it come from the southwest at a moderate angle? Many studies that needed to model the impact have simply defaulted to a 90-degree strike and avoided the whole argument. The details actually matter, though, and precisely which rocks get vaporized—and which climate-changing gases they release—depends on that impact angle.
A lot of new research on the crater has been published recently thanks to a major expedition that included drilling a rock core down through the crater’s peak ring. (Impacts this violent leave a raised ring in the center rather than a single peak.) A new paper led by Imperial College London’s Gareth Collins makes the latest contribution using model simulations to see what impact angle best matches the observed characteristics of the crater.
The Apple Card debuted 14 months ago, and right on cue, Samsung is today announcing "Samsung Money," a self-branded MasterCard debit card from SoFi. Unlike the Apple Card, which is a credit card, it sounds like Samsung Galaxy smartphone owners will be signing up for a money management account from SoFi, an online personal finance company The account is FDIC insured, has "no account fees," and even pays out interest for your savings.
Sign up for the account, and you'll get a physical "Samsung Money" card. It doesn't seem like Samsung tried to compete with Apple's fanciful titanium card design—the Samsung card looks like a regular plastic credit card with "dark mode" toggled on. Samsung did strip the card of numbers: it won't display the card number, expiration date, or CVV. Instead, you'll have to look those numbers up in the app, which is locked behind a pin or biometrics.
Users will be able to manage their new money management account from the Samsung Pay app. "With just a tap in the Samsung Pay app," Samsung's press release reads, "users can check their balance, review past statements, and search transactions. They can flag suspicious activity, pause or restart spending, freeze or unfreeze their card, change their pin, and assign their trusted contact—all without ever having to leave home or call a representative."
Solar energy is currently dominated by photovoltaic devices, which have ridden massive economies of scale to price dominance. But these devices are not necessarily the best choice in all circumstances. Unless battery technology improves, it's quite expensive to add significant storage to solar production. And there are types of transportation—long-distance rail, air—where batteries aren't a great solution. These limitations have made researchers maintain interest in alternate ways of using solar energy.
One alternative option is to use the energy to produce a portable fuel, like a hydrocarbon or hydrogen itself. This is possible to do with the electrons produced by photovoltaic systems, but the added steps can reduce efficiency. However, systems that convert sunlight more directly to fuel have suffered from even worse efficiencies.
But a Japanese group has decided to tackle this efficiency problem. The team started with a material that's not great—it only absorbs in the UV—but is well understood. And the researchers figured out how to optimize it so that its efficiency at splitting water to release hydrogen runs right up against the theoretical maximum. While it's not going to be useful on its own, it may point the way toward how to develop better materials.
General Electric has finally found a buyer for its lighting business and will be selling off its last consumer-facing business after more than 120 years of operation.
Boston-based GE said today it would divest the lighting business to Savant Systems, a smart home management company also based in Massachusetts. The companies did not disclose financial terms of the deal, but sources told The Wall Street Journal that the transaction was valued at about $250 million.
Savant specializes in full smart home systems for the luxury market. Acquiring a lighting business directly will allow it to take advantage of vertical integration and take more control over the physical equipment it installs in consumer' homes. Savant will keep the business's operations in Cleveland, where it is currently based, and will receive a long-term license to keep using the GE branding for its products.

When Chinese officials in the city of Wuhan discovered a cluster of just six COVID-19 cases around two weeks ago—the first cases there in more than a month—they quickly set an ambitious plan to test the entire city of roughly 11 million and crush a potential second wave of infection. And they initially planned to try to do it in just 10 days.
Ten days out, they nearly met that goal. Wuhan Municipal Health Commission swabbed more than 9 million residents and tested more than 6.5 million of those swabs for coronavirus genetic material between May 15 and May 24, according to state media.
Laboratories in the city went from conducting 46,000 tests a day to as many as 1.47 million in the screening sprint, according to The New York Times. The Times notes that in the US, New York tested 1.7 million people since March 4, a nearly three-month time frame, according to The Atlantic’s COVID Tracking Project.
In earlier coverage pitting ZFS against Linux kernel RAID, some readers had some concerns that we had missed some tricks for mdraid tuning. In particular, Louwrentius wanted us to retest mdadm with bitmaps disabled, and targetnovember thought that perhaps XFS might outperform ext4.
Write intent bitmaps are an mdraid feature that allows disks that have dropped off and re-entered the array to resync rather than rebuild from scratch. The "age" of the bitmap on the returning disk is used to determine what data has been written in its absence—which allows it to be updated with the new data only, rather than rebuilt from scratch.
XFS and ext4 are simply two different filesystems. Ext4 is the default root filesystem on most distributions, and XFS is an enterprise heavy-hitter most commonly seen in arrays in the hundreds or even thousands of tebibytes. We tested both this time, with bitmap support disabled.
The 16 purported fragments of the Dead Sea Scrolls in the Museum of the Bible might be fakes, but at least four such fragments housed at the University of Manchester in the UK are the real deal. For decades, those fragments were presumed to be blank, but a new analysis has revealed the existence of actual text, most likely a passage from the book of Ezekiel.
These ancient Hebrew texts—roughly 900 full and partial scrolls in all, stored in clay jars—were first discovered scattered in various caves near what was once the settlement of Qumran, just north of the Dead Sea, by Bedouin shepherds in 1946-1947. Qumran was destroyed by the Romans, circa 73 CE, and historians believe the scrolls were hidden in the caves by a sect called the Essenes to protect them from being destroyed. The natural limestone and conditions within the caves helped preserve the scrolls for millennia; they date back to between the third century BC and the first century CE.
The scrolls are understandably of great historical and archaeological interest. Several of the parchments have been carbon dated, and synchrotron radiation, among other techniques, has been used to shed light on the properties of the ink used for the text.
