Western Digital has been receiving a storm of bad press—and even lawsuits—concerning their attempt to sneak SMR disk technology into their "Red" line of NAS disks. To get a better handle on the situation, Ars purchased a Western Digital 4TB Red EFAX model SMR drive and put it to the test ourselves.
Recently, the well-known tech enthusiast site Servethehome tested one of the SMR-based 4TB Red disks with ZFS and found it sorely lacking. The disk performed adequately—if underwhelmingly—in generic performance tests. But when Servethehome used it to replace a disk in a degraded RAIDz1 vdev, it required more than nine days to complete the operation—when all competing NAS drives performed the same task in around sixteen hours.
This has rightfully raised questions as to what Western Digital was thinking when it tried to use SMR technology in NAS drives at all, let alone trying to sneak it into the market. Had Western Digital even tested the disks at all? But as valuable as Servethehome's ZFS tests were, they ignored the most common use case of this class of drive—consumer and small business NAS devices, such as Synology's DS1819+ or Netgear's ReadyNAS RN628X00. Those all use Linux kernel RAID (mdraid) to manage their arrays.
Americans are doing more housecleaning and disinfecting amid the COVID-19 pandemic and many are turning to wild and dangerous tactics—like drinking and gargling bleach solutions.
Back in April, the agency noted an unusual spike in poison control center calls over harmful exposures to household cleaning products, such as bleach. The timing linked it to the spread of the pandemic coronavirus, SARS-CoV-2 (not statements by President Trump). But to get a clearer idea of what was behind the rise, CDC researchers set up an online survey of household cleaning and disinfection knowledge and practices.
In all, they surveyed 502 US adults and used statistical weighting to make it representative of the country’s population. The findings—published Friday in the CDC's Morbidity and Mortality Weekly Report—are stunning.
Over the last few years, archaeologists have learned a lot from ancient people’s dirty dishes. Microscopic residues clinging to the inside of potsherds contain chemical traces of ancient food and drink, which have revealed remarkable details of ancient people’s diets. But as much as we now know about when people started eating certain grains or fermenting milk to make cheese, we’re still not sure when people first started brewing beer. It’s hard to tell a container used for beer from one that was just storing plain old grain.
But by looking at the remains of ancient grains under a microscope, archaeologists can tell whether the grains had been malted—the first step in the process of brewing beer.
When grains start to germinate, or sprout, they release an enzyme called diastase, which converts the grain’s stockpile of starch into sugar. The whole point of malting is to make the grains release diastase but then stop the process before the starch gets turned into sugar. Once the brewer adds yeast to the malted grain, then, the diastase can produce more sugar to feed the yeast—and that produces carbon dioxide, alcohol, and a sweet taste. To make this happen, brewers soak grains in water so they start to germinate, then stop the process by air-drying the grains and heating them in an oven.
When Amira Chowdhury joined a protest in Philadelphia against police violence on Monday, she wore a mask to protect herself and others against the coronavirus. But when officers launched tear gas into the crowd, Chowdhury pulled off her mask as she gasped for air. “I couldn’t breathe,” she said. “I felt like I was choking to death.”
Chowdhury was on a part of the Vine Street Expressway that ran underground. Everyone panicked as gas drifted into the dark, semi-enclosed space, she said. People stomped over her as they scrambled away. Bruised, she scaled a fence to escape. But the tear gas found her later that evening, inside her own house; as police unleashed it on protesters in her predominantly black neighborhood in West Philadelphia, it seeped in.
“I can’t even be in my own house without escaping the violence of the state,” said Chowdhury, a rising senior at the University of Pennsylvania. On Wednesday, she said her throat still felt dry, like it was clogged with ash.
Apple may soon add keyboard shortcuts for the iPad that would perform some of the actions Mac and PC users use the function or media keys for, according to 9to5Mac. The claim is based on analysis of code within iPadOS 13.5.5 beta.
When we reviewed the iPad Pro's new Magic Keyboard peripheral, one of our main complaints was the lack of physical media keys. Some features like managing media playback or changing screen brightness are available in the Control Center, which is a simple swipe away.
But others, like keyboard backlight brightness, have to be changed deep within the Settings app, whereas they could be changed with one or two taps on the MacBook Pro's Touch Bar or the MacBook Air's function keys. The Apple-made keyboard attachments for the various iPad models have no Touch Bar, and they lack function or media keys.
Motorola is releasing some cheap smartphones for 2020. You might think the company had already done this with the April release of the Moto G Stylus ($299) and the Moto G Power ($249), but today Motorola is announcing more budget devices for the US: the Moto G Fast ($199) and the 2020 version of the Moto E ($149).
Motorola's 2020 lineup of phones-at-$50-increments is getting pretty complicated, so maybe a big table would help:Moto E (2020) MOTO G FAST MOTO G POWER MOTO G STYLUS STARTING PRICE $149.99 $199.99 $249.99 $299.99 SCREEN 6.2-inch 1520×720p LCD 6.4-inch 1560×720p LCD 6.4-inch 2300×1080 LCD 6.4-inch 2300×1080 LCD CPU Snapdragon 632

One big oddity in Motorola's phone lineup is that none of these phones has NFC. You won't be able to use tap-and-pay with Google Pay anywhere, which is disappointing. They at least all have headphone jacks, Android 10, rear capacitive fingerprint readers, and Micro SD slots, which is nice. The Moto E is the only phone that is still using the dusty old Micro USB standard, which sadly is a normal occurrence at this price point.
The strategy, the explosions, the FMV sequences, the ripping guitars, and the Kane-fueled cheese—they're all back. The original 1995 game Command & Conquer: Tiberian Dawn and its 1996 prequel Red Alert have returned in today's launch of the C&C: Remastered Collection on Windows 8/10 (Amazon, Steam, Origin). In good news, the package is right for the price: $20 gets you both original games, all of their expansion packs (one for C&C:TD, two for Red Alert), and each game's console-exclusive content. The complete package has been aesthetically touched up for the sake of working on modern PCs.
I've spent the past week tinkering with Command & Conquer: Remastered Collection to break down exactly what to expect and how you should temper your real-time strategy expectations. Despite a few quality-of-life tweaks, the package is otherwise faithful to the originals—almost to a fault—while its compatibility with modern PCs is mostly good enough.From 400p to 2160p, but not without issues
The package's biggest selling point is a new coat of high-res paint. Every single asset and map element has been redrawn, and like other recent classic-game remaster projects, this one includes a handy "graphic-swap" button. By default, tap the space bar at any time during single-player modes to switch from the original 400p assets to a new, 2160p-optimized suite of units, buildings, and terrain. Here, enjoy an after-and-before gallery of both zoomed-in units and full battleground scenes.
A major investment group with substantial holdings in Activision stock is speaking out this week against the high compensation for Activision Blizzard CEO Bobby Kotick. The move comes ahead of a shareholder vote on executive pay scheduled for June 11.
"Over the past four years, Activision Blizzard CEO Robert Kotick has received over $20 million in combined stock/option equity per year," the CtW investment group writes in a letter filed with the SEC this week. "These equity grants have consistently been larger than the total pay (the sum of base salary, annual bonus, and equity pay) of CEO peers at similar companies."
CtW—which works with union-sponsored pension funds to speak out against "irresponsible and unethical corporate behavior and excessive executive pay"—said Kotick's excessive compensation is especially concerning in light of the wave of nearly 800 layoffs the company rolled out in 2019. Those layoffs were implemented amid the announcement of "record results in 2018" for Activision and reportedly focused on "non-development teams" that were no longer needed thanks to a lighter slate of releases from the company going forward.
For decades now, video games have concerned themselves with the end of things. From the bombed-out nuclear wasteland of Washington, DC in Fallout 3 to the flooded Hyrule of The Legend of Zelda: Wind Waker, popular games have explored the concept of the apocalypse with both goofy humor and stark seriousness, often revealing unpleasant truths in the process. So perhaps it’s no surprise that as the all-too-real climate change crisis continues to creep towards a breaking point—even as the ongoing public health disaster known as COVID-19 eclipses it in the public imagination—video game developers are taking steps to systematize the ways that rising sea levels or other ecological catastrophes might overwhelm us in the coming years.
While many of these climate changed-focused games focus on depicting the dire future that experts predict if we refuse to radically alter our behavior patterns, others are a bit more traditional in their approach. And some notable game-makers like Firaxis Games (Civilization) and 11-Bit Studios (This War of Mine) are drawing inspiration from climate-change to craft ludic dilemmas that force players to make radical decisions in the face of overwhelming odds. In other words: if these studios can't necessarily make living through the apocalypse as fun as it sounds, they can at least make it interesting.A game that can do both
To be fair, climate scientists have understood for years now that video games have a unique ability to communicate the stakes and severity of this global crisis to a mass audience. Historically, many of these games fit well-within the strategy genre, and developers have tried different approaches to lure players in. For example, the commercial game Fate of the World often overwhelms new players with the heft of its interlocking systems: make a few bad decisions early on, and you'll quickly find yourself hurtling towards a bad ending. All you can do then is apply the lessons learned to a future playthrough. On the other hand, educational fare like the underwater exploration sim Beyond Blue lean more towards accessibility. By focusing on the specific effects of climate change—in this case, the destruction of the Earth's oceans—the game can communicate the costs of a warming climate to a wider audience.
Welcome to Edition 3.03 of the Rocket Report! We just passed a week of the highest of highs, with Saturday's Crew Dragon launch, and the lowest of lows, as this country's racial prejudice was laid bare. Jeff Manber, the CEO of Nanoracks, said it well: "The space community can, and must, do better to become part of the solution to the horrific challenges America faces today." We agree.

We at Ars Technica are proud to be members of video game archiving history today. SimRefinery, one of PC gaming's most notoriously "lost" video games, now exists as a fully playable game—albeit an unfinished one—thanks to an Ars Technica reader commenting on the story of its legend.
Two weeks ago, I reported on a story about Maxis Business Solutions, a subdivision of the game developer Maxis created in the wake of SimCity's booming success. Librarian and archivist Phil Salvador published an epic, interview-filled history of one of the game industry's earliest examples of a "serious" gaming division, which was formed as a way to cash in on major businesses' interest in using video games as work-training simulators.
As Salvador wrote in May:
State-backed hackers from Iran and China recently targeted the presidential campaigns of Republican President Donald Trump and Democrat Joe Biden, a Google threat analyst said on Thursday.
The revelation is the latest evidence of foreign governments attempting to gain intelligence on US politicians and potentially disrupt or meddle in their election campaigns. An Iran-backed group targeted the Trump campaign, and China-backed attackers targeted the Biden campaign, said Shane Huntley, the head of Google’s Threat Analysis Group on Twitter. Both groups used phishing emails. There’s no indication that either attack campaign succeeded.Kittens and Pandas
Huntley identified the Iranian group that targeted Trump’s campaign as APT35, short for Advanced Persistent Threat 35. Also known as Charming Kitten, iKittens, and Phosphorous, the group was caught targeting an unnamed presidential campaign before, Microsoft said last October. In that campaign, Phosphorous members attempted to access email accounts campaign staff received through Microsoft cloud services. Microsoft said that the attackers worked relentlessly to gather information that could be used to activate password resets and other account-recovery services Microsoft provides.
A rogue detective who doesn't always play by the rules hunts a costumed vigilante serial killer in the first English-language trailer (well, subtitled) for a Russian superhero film called Major Grom: Plague Doctor, directed by Oleg Trofim (Ice). There's some pretty strong The Punisher vibes here, as well as V for Vendetta. The Major Grom comic books, created by Artem Gabrelyanov, have been likened to the early Batman comics in tone, which might explain the Dark Knight overtones as well.
(Some spoilers for the Russian comics below.)
The original Major Grom comics were published between 2012 and 2015, later spawning several spinoffs. The protagonist is Major Igor Grom, a detective in St. Petersburg who has mean martial arts skills and takes part in the occasional amateur boxing competition (aka Russian Fight Club). He has a tendency to bend the rules, which irritates his young rookie partner, Dmitry "Dima" Dubin, who prefers to play things by the book. Grom's love interest is an investigative reporter named Yulia Pchelkina, whose skill set proves useful in helping solve Grom's various comic book cases. A billionaire social media mogul named Sergey Razumovsky is Grom's archnemesis. Razumovsky is a philanthropist by day but murders homeless people by night, all in the name of cleaning up St. Petersburg.
What's the best way to protect yourself when you're at risk of exposure to SARS-CoV-2? It seems like a simple question, but many of the options—face masks, lockdowns, social distancing, etc.—have been politically controversial. In addition, it has been difficult for public health authorities to maintain a consistent message, given our changing state of knowledge and their need to balance things like maintaining supplies of protective equipment for health care workers.
But several months into the pandemic, we've started to get a clear indication that social isolation rules are helping, providing support for those policies. So, where do we stand on the use of masks?
Two recent events hint at where the evidence is running. The first involves the retraction of a paper that appeared to show that mask use was ineffective. And the second is a meta-analysis of all recent studies on the use of protective gear against SARS-CoV-2 and its relatives SARS and MERS. It finds support for a protective effect of masks—as well as eye protection—although the underlying evidence isn't as strong as we might like.
Instagram does not provide users of its embedding API a copyright license to display embedded images on other websites, the company said in a Thursday email to Ars Technica. The announcement could come as an unwelcome surprise to users who believed that embedding images, rather than hosting them directly, provides insulation against copyright claims.
"While our terms allow us to grant a sub-license, we do not grant one for our embeds API," a Facebook company spokesperson told Ars in a Thursday email. "Our platform policies require third parties to have the necessary rights from applicable rights holders. This includes ensuring they have a license to share this content, if a license is required by law."
In plain English, before you embed someone's Instagram post on your website, you may need to ask the poster for a separate license to the images in the post. If you don't, you could be subject to a copyright lawsuit.
Smartphones have always been the modern tech equivalent of a Swiss Army knife, combining a phone, a music player, a camera, a GPS, a PDA, and more into a single device. Now Huawei is pitching yet another device that can be integrated into a smartphone: a thermometer. Huawei's Honor Play 4 Pro has an IR temperature sensor integrated into the rear camera block that can measure the surface temperature of people and objects. In a year when containing the spread of the coronavirus pandemic is a major concern and a fever can be an early indicator of infection, the Play 4 Pro is an extremely 2020 smartphone.
In a video posted on the Chinese social media site Weibo, Huawei demonstrates how the feature will work. Just aim the phone at someone's forehead, tap through the app, and the phone will give you a temperature reading. Temperature checks aren't a guaranteed way to screen for COVID-19, but a fever is a symptom in the majority of hospitalized cases, and it's very easy to check for. The use of infrared non-contact thermometers is a common sight in Huawei's home country of China, and in the United States, employers like Amazon and Walmart are screening masses of warehouse employees for fevers as part of coronavirus control.
Huawei says its IR sensor can read temperatures from -20°C (-4°F) to 100°C (212°F). An IR sensor isn't as accurate as a thermal camera, and neither device, which reads a surface temperature, is as accurate as an internally taken temperature. An IR sensor is cheap, though, and they are already frequently integrated into a smartphone for face unlock and camera effects, so Huawei was able to quickly react to the pandemic.
Nearly 30 years ago, theoretical physicists introduced the "holographic principle," a mind-bending theory positing that our three-dimensional universe is actually a hologram. Now physicists are applying that same principle to black holes, arguing in a new paper published in Physical Review X that a black hole's information is contained within a two-dimensional surface, which is able to reproduce an image of the black hole in three dimensions—just like the holograms we see in everyday life.
Black holes as described by general relativity are simple objects. All you need to describe them mathematically is their mass and their spin, plus their electric charge. So there would be no noticeable change if you threw something into a black hole—nothing that would provide a clue as to what that object might have been. That information is lost.
But problems arise when quantum gravity enters the picture because the rules of quantum mechanics hold that information can never be destroyed. And in quantum mechanics, black holes are incredibly complex objects and thus should contain a great deal of information. As we reported previously, Jacob Bekenstein realized in 1974 that black holes also have a temperature. Stephen Hawking tried to prove him wrong but wound up proving him right instead, concluding that black holes therefore had to produce some kind of thermal radiation.
The Lancet medical journal on Thursday announced the retraction of a dubious study suggesting that the anti-malaria drugs chloroquine and hydroxychloroquine significantly increased the risk of death and heart-rhythm complications in hospitalized COVID-19 patients worldwide.
Three of the study’s four authors made the decision to retract the study after they were unable to independently verify the data used for their analysis. The data was provided by an obscure data analytics company, Surgisphere, which is run by the fourth author of the study, Sapan S Desai, who did not appear to agree to the retraction.
The three retracting authors—Mandeep R. Mehra of Harvard, Frank Ruschitzka of University Hospital Zurich, and Amit Patel of the University of Utah—said in their retraction notice that Surgisphere refused to hand over its full dataset and an audit report of its servers for an independent peer review. “Based on this development, we can no longer vouch for the veracity of the primary data sources,” the wrote.
Draft league is probably nothing like the Pokémon you're familiar with. It's not training up a team of your favorite Pokémon to beat Team Rocket. It's not even like an official competitive tournament run by The Pokémon Company.
And it all started with a bumper sticker.
Steve "Magnitude" Wood is the YouTuber and sports fanatic who came up with the concept of combining his two passions. "I'm a huge Milwaukee Bucks basketball fan," he tells Ars Technica. "And I thought the Pokémon Sawsbuck looks a lot like the Milwaukee Bucks logo. One of my friends was a graphic designer, so she made me a sticker, and I got it printed and put it on my car."
The coronavirus pandemic caused big ISPs to put data caps on hold for a few months, but one small ISP is going a big step further and canceling the arbitrary monthly limits permanently. Antietam Broadband, which serves Washington County in Maryland, announced Friday that it "has permanently removed broadband data usage caps for all customers," retroactive to mid-March when the company first temporarily suspended data-cap overage fees.
The decision to permanently drop the cap was made partly because of "learnings from the COVID-19 pandemic as more people worked and learned remotely," Antietam explained. "During this period customers moved into broadband packages that more accurately reflected their broadband needs." Like most other ISPs, Antietam charges different prices based on speed tiers as measured in bits per second, with Antietam's advertised download speeds ranging up to 1Gbps.
"These are uncertain times. We felt a need to give customers as much certainty over their bill as possible," Antietam President Brian Lynch said in the press release. "Eliminating data usage caps means that customers will know the exact amount of their broadband bill every month."
