Uncovered: 1,000 Phrases That Incorrectly Trigger Alexa, Siri, and Google Assistant

Wed, 2020-07-01 22:02
An anonymous reader quotes a report from The Wall Street Journal: As Alexa, Google Home, Siri, and other voice assistants have become fixtures in millions of homes, privacy advocates have grown concerned that their near-constant listening to nearby conversations could pose more risk than benefit to users. New research suggests the privacy threat may be greater than previously thought. The findings demonstrate how common it is for dialog in TV shows and other sources to produce false triggers that cause the devices to turn on, sometimes sending nearby sounds to Amazon, Apple, Google, or other manufacturers. In all, researchers uncovered more than 1,000 word sequences -- including those from Game of Thrones, Modern Family, House of Cards, and news broadcasts -- that incorrectly trigger the devices. "The devices are intentionally programmed in a somewhat forgiving manner, because they are supposed to be able to understand their humans," one of the researchers, Dorothea Kolossa, said. "Therefore, they are more likely to start up once too often rather than not at all." When devices wake, the researchers said, they record a portion of what's said and transmit it to the manufacturer. The audio may then be transcribed and checked by employees in an attempt to improve word recognition. The result: fragments of potentially private conversations can end up in the company logs. The research paper, titled "Unacceptable, where is my privacy?," hasn't yet been published, although a brief write-up of the findings can be found here.

Zoom Misses Its Own Deadline To Publish Its First Transparency Report

Wed, 2020-07-01 21:25
How many government demands for user data has Zoom received? We won't know until "later this year," an updated Zoom blog post now says. From a report: The video conferencing giant previously said it would release the number of government demands it has received by June 30. But the company said it's missed that target and has given no firm new date for releasing the figures. It comes amid heightened scrutiny of the service after a number of security issues and privacy concerns came to light following a massive spike in its user base, thanks to millions working from home because of the coronavirus pandemic. In a blog post today reflecting on the company's turnaround efforts, chief executive Eric Yuan said the company has "made significant progress defining the framework and approach for a transparency report that details information related to requests Zoom receives for data, records or content. We look forward to providing the fiscal [second quarter] data in our first report later this year," he said. Transparency reports offer rare insights into the number of demands or requests a company gets from the government for user data. These reports are not mandatory, but are important to understand the scale and scope of government surveillance.

Detroit Police Chief: Facial Recognition Software Misidentifies 96% of the Time

Wed, 2020-07-01 20:45
Detroit police have used highly unreliable facial recognition technology almost exclusively against Black people so far in 2020, according to the Detroit Police Department's own statistics. From a report: The department's use of the technology gained national attention last week after the American Civil Liberties Union and New York Times brought to light the case of Robert Julian-Borchak Williams, a man who was wrongfully arrested because of the technology. In a public meeting Monday, Detroit Police Chief James Craig admitted that the technology, developed by a company called DataWorks Plus, almost never brings back a direct match and almost always misidentifies people. "If we would use the software only [to identify subjects], we would not solve the case 95-97 percent of the time," Craig said. "That's if we relied totally on the software, which would be against our current policy ... If we were just to use the technology by itself, to identify someone, I would say 96 percent of the time it would misidentify."

Ads Are Taking Over Samsung's Galaxy Smartphones

Wed, 2020-07-01 20:05
Max Weinbach, writing for Android Police: I have been using Samsung phones every day for almost 4 years. It was because Samsung had fantastic hardware paired with --depending on the year -- good software. 2020 is the first year in a while I'm not using a Samsung phone as my daily driver. The reason? Ads. Ads in Samsung phones never really bothered me, at least not until the past few months. It started with the Galaxy Z Flip. A tweet from Todd Haselton of CNBC is what really caught my eye. Samsung had put an ad from DirectTV in the stock dialer app. This is really something I never would have expected from any smartphone company, let alone Samsung. It showed up in the "Places" tab in the dialer app, which is in partnership with Yelp and lets you search for different businesses directly from the dialer app so you don't need to Google somewhere to find the address or phone number. I looked into it, to see if this was maybe a mistake on Yelp's part, accidentally displaying an ad where it shouldn't have, but nope. The ad was placed by Samsung, in an area where it could blend in so they could make money. Similar ads exist throughout a bunch of Samsung apps. Samsung Music has ads that look like another track in your library. Samsung Health and Samsung Pay have banners for promotional ads. The stock weather app has ads that look like they could be news. There is also more often very blatant advertising in most of these apps as well. Samsung Music will give you a popup ad for Sirius XM, even though Spotify is built into the Samsung Music app. You can hide the SiriusXM popup, but only for 7 days at a time. A week later, it will be right back there waiting for you. Samsung will also give you push notification ads for new products from Bixby, Samsung Pay, and Samsung Push Service.

A Massive Star Has Seemingly Vanished from Space With No Explanation

Wed, 2020-07-01 19:25
Astronomers are perplexed by the unexplained disappearance of a massive star located 75 million light years away. From a report: A decade ago, light from this colossal star brightened its entire host galaxy, which is officially known as PHL 293B and is nicknamed the Kinman Dwarf. But when scientists checked back in on this farflung system last summer, the glow of the star -- estimated to be roughly 100 times more massive than the Sun -- had been extinguished. The head-scratching discovery was announced in a study published on Tuesday in the Monthly Notices of the Royal Astronomical Society. "We were quite surprised when we couldn't find the star," said lead author Andrew Allan, a PhD student at Trinity College Dublin, in a call. "It is a very extreme star, and it has quite a strong wind, so we can distinguish it from the galaxy. That's what we couldn't see in the newer observations." The mysterious series of events began when Allan and his colleagues imaged the Kinman Dwarf in August 2019, using the ESPRESSO instrument at the Very Large Telescope in Chile. The team initially set out to learn more about massive stars located in galaxies with low metal densities. Given that the starlit Kinman Dwarf had been observed by other astronomers between 2001 and 2011, the team knew that it would be a good target for their research. "Not a lot is understood about stars in those kinds of environments, so that was the main reason we wanted to look," Allan said. "We are interested in massive stars at the end of their lives in those kinds of environments, so we were really just hoping to get a better resolution observation."

Tesla Becomes Most Valuable Automaker in Latest Stock Rally

Wed, 2020-07-01 18:45
Tesla on Wednesday became the highest-valued automaker as its shares surged to record highs and the electric carmaker's market capitalization overtook that of former front runner Toyota Motors. From a report: Tesla shares gained 5% in early morning trade to a record of $1,133, boosting the company's market cap to $209.47 billion - roughly $6 billion more than Toyota is currently valued by investors. Tesla is now worth more than triple the combined value of U.S. automakers General Motors Co and Ford Motor Co. The shares' meteoric rise, up more than 163% since the start of 2020, highlight growing confidence among investors about the future of electric vehicles and Tesla's shift from a niche carmaker into a global leader in cleaner cars. After several years of losses, Tesla has delivered three straight profitable quarters since the third quarter of 2019 and surprised investors with solid first-quarter deliveries despite the virus outbreak.

MIT Apologizes, Permanently Pulls Offline Huge Dataset That Taught AI Systems To Use Racist, Misogynistic Slurs

Wed, 2020-07-01 18:04
MIT has taken offline its highly cited dataset that trained AI systems to potentially describe people using racist, misogynistic, and other problematic terms. From a report: The database was removed this week after The Register alerted the American super-college. And MIT urged researchers and developers to stop using the training library, and to delete any copies. "We sincerely apologize," a professor told us. The training set, built by the university, has been used to teach machine-learning models to automatically identify and list the people and objects depicted in still images. For example, if you show one of these systems a photo of a park, it might tell you about the children, adults, pets, picnic spreads, grass, and trees present in the snap. Thanks to MIT's cavalier approach when assembling its training set, though, these systems may also label women as whores or bitches, and Black and Asian people with derogatory language. The database also contained close-up pictures of female genitalia labeled with the C-word. Applications, websites, and other products relying on neural networks trained using MIT's dataset may therefore end up using these terms when analyzing photographs and camera footage. The problematic training library in question is 80 Million Tiny Images, which was created in 2008 to help produce advanced object detection techniques. It is, essentially, a huge collection of photos with labels describing what's in the pics, all of which can be fed into neural networks to teach them to associate patterns in photos with the descriptive labels. So when a trained neural network is shown a bike, it can accurately predict a bike is present in the snap. It's called Tiny Images because the pictures in library are small enough for computer-vision algorithms in the late-2000s and early-2010s to digest.

Minecraft Is Now Home To a Virtual Library of Censored Journalism

Wed, 2020-07-01 17:21
schwit1 shares a report: Free press advocates have created a virtual library in Minecraft that bypasses censorship in oppressive countries to house censored journals and articles. The virtual space was created as a collaboration between the freedom-of-the-press organization, Reporters Without Borders, and a Minecraft design company, BlockWorks. Because Minecraft isn't blocked in many places -- at least, not yet -- it's an ingenious way to ensure access even for those living under repressive regimes. The Uncensored Library, as it's called, houses information on all 180 countries in the press freedom index, as well as exhibition halls on countries notorious for their press censorship, like Russia and Vietnam. BlockWorks says that journalists across five countries who've seen their works banned were able to republish their articles in the exhibition halls for their respective countries, giving them a chance to inform the world about the situation on the ground. There are also areas in the exhibition halls honoring journalists who have been silenced, including Nguyen Van Dai, Yulia Beerezovskaia, and Jamal Khashoggi, the Saudi journalist who was brutally murdered, allegedly at the behest of Saudi Arabia's Crown Prince, Mohammad Bin Salman.

Alphabet-owned Verily Suspended Employee Bonuses To Fund Diversity Initiatives

Wed, 2020-07-01 16:42
Verily Life Sciences, the Alphabet-owned healthcare company, is suspending employee spot bonuses. From a report: The money will be funneled instead to fund diversity and inclusion initiatives. The move frustrated workers, many of whom have been working grueling hours on the company's COVID-19 testing projects. In a letter to management obtained by Business Insider, employees said the decision implied these initiatives are not a priority. They wrote: "The use of spot bonuses to subsidize social justice programs such as Healthy@Work for HBCUs [Historically Black colleges and universities], clinical trial recruitment of underrepresented populations, and an internal Product Inclusion group implies that these efforts are charity causes not worthy of their own investment." Employees asked that spot bonuses be reinstated and called for the creation of a board of executives and employees to measure progress toward diversity goals. Alphabet, Verily's parent company, made $46.07 billion in revenue in the fourth quarter of 2019. Because of Alphabet's strong financial position, diversity and inclusion shouldn't be hard to invest in, the employees wrote.

China's Influence Via WeChat Is 'Flying Under the Radar' of Most Western Democracies

Wed, 2020-07-01 16:04
China's WeChat, like most social networks, is a haven for disinformation and "fake news". Less well-known, at least in the West, is its role in mobilising Chinese diaspora communities to support particular political policies or people, according to a report. schwit1 shares the report: These activities are coordinated through a system known as the United Front, a network of party and state agencies that are responsible for influencing purportedly independent groups outside the Chinese Communist Party. At the very top, the United Front Work Department is led by China's fourth most senior political leader, Wang Yang. President Xi Jinping and his family have been involved in United Front work for decades. "Where United Front really works their biggest magic is actually on social media WeChat," says Maree Ma, general manager of Vision Times, a leading Chinese-language Australian media outlet. WeChat's private groups are capped at 500 members, but according to Ma, there's "hundreds" of United Front organisations in Australia, each of them with many of these groups.

After Lackluster Launch, Amazon Pulls 'Crucible' Back Into Closed Beta Weeks After Game's Release

Wed, 2020-07-01 15:25
Little more than a month after a much-hyped entry into big-budget video games, Amazon is pulling back "Crucible," its new free-to-play PC shooter, and moving the title to closed beta. From a report: "Crucible" is developed by Amazon-owned Relentless Studios, and in a blog post on Tuesday, franchise lead Colin Johanson cited the need to "focus on providing the best possible experience for our players as we continue to make the game better." The game has failed to generate much positive traction. The Verge said "lackluster characters, combat, and art style made it largely forgettable" and that "Crucible" also suffered from "a bit of an identity crisis by trying to be a bit of everything at once." According to Business Insider, "Crucible" had around 25,000 concurrent players at peak, the day after its launch. Two days after launch, it had already disappeared from Steam's top 100 -- a list of most-played games on Steam that bottoms out around 5,000 concurrent players. Players who have downloaded the game will still be able to play it through Steam. "One of the biggest changes you'll see is that we're going to schedule dedicated time each week when we as devs will be playing with the community and soliciting feedback," Johanson wrote. "When we exit beta, it will be based on your feedback and the metrics that we see in-game."

Sydney Now Powered By 100% Renewable Electricity

Wed, 2020-07-01 14:49
The City of Sydney is now powered by 100% renewable electricity, generated from wind and solar farms in regional New South Wales. From a report: The "green energy" deal which came into effect on Wednesday is valued at over $60 million and is touted by the City of Sydney Council as the biggest green energy deal of its kind by a council in Australia. Under the deal, all the city of Sydney operations -- including street lights, pools, sports fields, depots, buildings and the historic Sydney Town Hall -- will now be run on 100% renewable electricity from locally-sourced clean energy. The Council says the switch is projected to save the City up to half a million dollars a year over the next 10 years, and reduce C02 emissions by around 20,000 tonnes a year -- the equivalent to the power consumption of more than 6,000 households. Lord Mayor Clover Moore said the new agreement will generate jobs, support communities impacted by the Covid-19 pandemic and create new opportunities in drought-affected regional NSW. "We are in the middle of a climate emergency. If we are to reduce emissions and grow the green power sector, all levels of government must urgently transition to renewable energy," the Lord Mayor said. "Cities are responsible for 70 per cent of greenhouse gas emissions worldwide, so it is critical that we take effective and evidence-based climate actions. The City of Sydney became carbon neutral in 2007, and were the first government in Australia to be certified carbon neutral in 2011. This new deal will see us reach our 2030 target of reducing emissions by 70 per cent by 2024, six years early. This ground-breaking $60 million renewable electricity deal will also save our ratepayers money and support regional jobs in wind and solar farms in Glen Innes, Wagga Wagga and the Shoalhaven."

Apple Races To Push Ahead With 5G iPhone Mass Production

Wed, 2020-07-01 14:05
Apple is pushing its suppliers to try to reduce production delays for its first 5G iPhones as the U.S. tech company aims to limit the fallout from the coronavirus pandemic. From a report: Apple is facing delays of between four weeks and two months for mass production of the four models in its 5G lineup after postponements caused by factory lockdowns and workplace absences during the pandemic, sources told the Nikkei Asian Review. Apple has been betting heavily on the 5G range to help it against rivals including Samsung and Huawei Technologies, which introduced 5G-capable smartphones last year. But sources said Apple has aggressively tried to cut delays and was now less likely to face a worst-case scenario of postponing the launch until 2021, the situation it was in three months ago. The estimated delays are based on the stage that development would normally be at for a release in September. The tech giant and its suppliers are working overtime to make up for lost time, people with knowledge of the matter said. "What the progress looks like now is months of delay in terms of mass production, but Apple is doing everything it can to shorten the postponement. There's a chance that the schedule could still be moved ahead," one of the sources told Nikkei. California, where Apple is based, came under "shelter at home" restrictions in March, though the order was revised in June to allow more businesses to reopen. Part of Apple's hardware development team returned to the head office last month as the company attempted to expedite the final configuration of the new iPhones and keep as close as possible to the intended September release date, according to another source familiar with the situation.

Supreme Court Says Generic Domains Like Booking.com Can Be Trademarked

Wed, 2020-07-01 13:00
An anonymous reader quotes a report from Ars Technica: The U.S. Patent and Trademark Office erred by finding the term booking.com was too generic for trademark protection, the Supreme Court ruled on Tuesday. Trademark law prohibits anyone from registering generic terms that describe a class of products or services. Anyone can start a store company called "The Wine Company," but they can't use trademark law to stop others from using the same name. When the online travel giant Bookings Holdings sought to trademark its booking.com domain name almost a decade ago, the U.S. Patent and Trademark Office concluded that the same rule applied. Booking Holdings challenged this decision in court. The company pointed to survey data showing that consumers associated the phrase "booking.com" with a specific website as opposed to a generic term for travel websites. Both the trial and appeals courts sided with booking.com, finding that booking.com was sufficiently distinctive to merit its own trademark -- even if the generic word "booking" couldn't be trademarked on its own. Trademark law declines to protect generic terms in an effort to promote competition. If a company could trademark a word like "booking" or "wine," it could interfere with competitors who want to accurately describe their products in the marketplace. That would give companies that trademark generic terms an unfair advantage. But an opinion by Justice Ruth Bader Ginsburg (and joined by seven other justices) found that this wasn't a serious concern for dot-com trademarks. A company like Travelocity or Expedia might describe itself as "a booking website," but it would never describe itself as "a booking.com." Ginsburg notes that the rules of the domain-name system ensure that only one company can use a name like booking.com, so consumers are likely to understand that "booking.com" refers to a particular website -- it's not a generic term for booking websites in general.

Earth's Final Frontier: The Global Race To Map the Entire Ocean Floor

Wed, 2020-07-01 10:00
AmiMoJo shares a report from The Guardian: An ambitious project to chart the seabed by 2030 could help countries prepare for tsunamis, protect marine habitats and monitor deep-sea mining. But the challenge is unprecedented. The race officially kicked off in 2017 at the United Nations Ocean Conference in New York City. When it began, around 6% of the ocean was mapped in accurate detail. On June 21, the global initiative -- known formally as the Nippon Foundation-Gebco Seabed 2030 Project -- released its latest edition: it has now mapped one-fifth of the seafloor. Few countries need accurate maps of the seabed more than Japan, an island nation whose future is uniquely intertwined with the ocean's, and it is the Nippon Foundation , a Japanese non-profit organization run on the gambling proceeds of motorboat racing, that is backing Seabed 2030 with $2m every year. [...] But the mapping is a truly global collaboration, public and free to use, divided among four regional centers. The Alfred Wegener Institute in Germany took the Southern Ocean; Stockholm University and the University of New Hampshire cover the North Pacific and Arctic; New Zealand's National Institute of Water and Atmospheric Research are responsible for the South and West Pacific Ocean. That leaves the largest swath, the entire Atlantic and Indian Oceans, to the Lamont-Doherty Earth Observatory at Columbia University -- Ferrini's team. The finished map itself is created by a fifth centre, based in the UK: the British Oceanographic Data Centre in Southampton. It collects the analyzed data from the four centers and compiles it in the General Bathymetric Chart of the Oceans (Gebco). The data is in the public domain, free to use, adapt and commercially exploit.

Asteroid Impact, Not Volcanic Activity, Killed the Dinosaurs, Study Finds

Wed, 2020-07-01 07:00
Scientists have gone back and forth over exactly what caused a mass extinction event 66 million years ago, which destroyed about 75% of all life on Earth, including all of the large dinosaurs. Some have thought that volcanic activity could be to blame, but one new study shows that a giant asteroid impact was the prime culprit. Space.com reports: In a new study, researchers from Imperial College London, the University of Bristol and University College London have shown that the asteroid impact, not volcanic activity, was the main reason that about 75% of life on Earth perished at that time, and it did so by significantly interfering with Earth's climate and ecosystems. To come to this conclusion, the researchers modeled how Earth's climate would be expected to respond to two separate possible extinction causes: volcanism and asteroid impact. In these mathematical models, they included environmental factors including rainfall and temperature, which would have been critical to the survival of these species. They also included the presence of sunlight-blocking gases and particles and carbon dioxide, a greenhouse gas. With these models, the team found that the giant asteroid hitting our planet would have released tremendous amounts of gas and particles into Earth's atmosphere, blocking out the sun for years on end. This effect would have created a sort of semi-permanent winter on Earth, making the planet unlivable for most of its inhabitants. Now, while the team found the asteroid impact to be the major factor in making Earth unlivable for most animals, they also found that volcanic activity could have actually helped life to recover over time, a conclusion that scientists have drawn before. They found that, while volcanoes do release sunlight-blocking gases and particles, which would have helped to block the sun in the short term, they also release large amounts of carbon dioxide which, because it's a greenhouse gas, would have built up in the atmosphere and warmed the planet. So, as the researchers suggest in this work, while the devastating winter caused by the asteroid killed off most life on Earth, over time, the warming effect created from the volcanic greenhouse gases could have helped to restore life to habitats. The study has been published in the journal Proceedings of the National Academy of Sciences.

Dr. Anthony Fauci Says New Virus In China Has Traits of 2009 Swine Flu, 1918 Pandemic Flu

Wed, 2020-07-01 03:30
An anonymous reader quotes a report from CNBC: White House coronavirus advisor Dr. Anthony Fauci said Tuesday that U.S. health officials are keeping an eye on a new strain of flu carried by pigs in China that has characteristics of the 2009 H1N1 virus and 1918 pandemic flu. The virus, which scientists are calling "G4 EA H1N1," has not yet been shown to infect humans but it is exhibiting "reassortment capabilities," Fauci, director of the National Institute of Allergy and Infectious Diseases, told the Senate Health, Education, Labor and Pensions Committee during a hearing. "In other words, when you get a brand new virus that turns out to be a pandemic virus it's either due to mutations and/or the reassortment or exchanges of genes," he told lawmakers. "And they're seeing virus in swine, in pigs now, that have characteristics of the 2009 H1N1, of the original 1918, which many of our flu viruses have remnants of that in it, as well as segments from other hosts, like swine." Fauci said Tuesday there's always "the possibility that you might have another swine flu-type outbreak as we had in 2009." "It's something that still is in the stage of examination," he said. It's not "an immediate threat where you're seeing infections, but it's something we need to keep our eye on, just the way we did in 2009 with the emergence of the swine flu."

Declining Eyesight Can Be Improved By Looking At Red Light, Pilot Study Says

Wed, 2020-07-01 00:10
swell shares the findings from a small pilot study that suggests a few minutes of looking into a deep red light could have a dramatic effect on preventing eyesight decline as we age. CNN reports: Researchers recruited 12 men and 12 women, whose ages ranged from 28 to 72. Each participant was given a small handheld flashlight that emitted a red light with a wavelength of 670 nanometers. That wavelength is toward the long end of the visible spectrum, and just short of an infrared wavelength, which tends to be invisible to the human eye. They spent three minutes each day looking into the light over a period of two weeks. The lights work on both cones and rods in the eye. Cones are photo receptor cells that detect color and work best in well-lit situations. Rods, which are much more plentiful, are retina cells that specialize in helping us see in dim light, according to the American Academy of Ophthalmology. Researchers measured the cone function in subjects' eyes by having them identify colored letters with low contrast. And they measured their eyes' rod sensitivity by asking them to detect light signals in the dark. There was a 14% improvement in the ability to see colors, or cone color contrast sensitivity, for the entire two dozen participants. Improvement, however, was most significant in study participants over age 40. For those ages, cone color contrast sensitivity rose by 20% over the course of the study. That age bracket also saw significant increases in rod threshold, which corresponds to the ability to see in low light. Study participants under 40 also experienced some improvement, but didn't see the same jump as older subjects. Younger eyes haven't declined as much as older eyes.

Someone Mysteriously Sent Almost $1 Billion In Bitcoin

Tue, 2020-06-30 23:30
Someone transferred bitcoins worth close to $1 billion on Tuesday morning, a move that was public for everyone to see while the identities of the sender and receiver remain unknown. Motherboard reports: Big money moves hiding in plain sight tend to be events of some interest among Bitcoiners. Decrypt noted that the sending wallet was recognized as the largest Bitcoin wallet not known to be associated with a business such as an exchange. This means that it could belong to a wealthy private individual, or it could really belong to an exchange, investor, or other business that is simply currently unknown. There's no obligation to publicize which Bitcoin addresses one controls, and if nobody else puts two and two together, one's activities may remain shrouded in pseudonymity. If the Bitcoin wallet belongs to someone legit, then it's likely the transfer was internal to the business, or it represents a large purchase of goods or services, or the sale of bitcoins. Regardless of what it was, the business would be expected to pay taxes in any relevant circumstances. If the transfer wasn't legit, well, pseudonymity and the ability to freely move money without the pre-approval of an authority is the point of Bitcoin. That being said, law enforcement is certainly aware of Bitcoin at this stage in the game and if I'm talking about this transfer then I'm sure more important people could be, too.

400 TB Storage Drives In Our Future: Fujifilm

Tue, 2020-06-30 22:50
One of the two leading manufacturers of tape cartridge storage, FujiFilm, claims that they have a technology roadmap through to 2030 which builds on the current magnetic tape paradigm to enable 400 TB per tape. AnandTech reports: As reported by Chris Mellor of Blocks and Files, Fujifilm points to using Strontium Ferrite grains in order to enable an areal data density on tape of 224 Gbit-per-square-inch, which would enable 400 TB drives. IBM and Sony have already demonstrated 201 Gbit-per-square-inch technology in 2017, with a potential release of the technology for high volume production in 2026. Current drives are over an order of magnitude smaller, at 8 Gbit-per-square-inch, however the delay between research and mass production is quite significant. Strontium Ferrite would replace Barium Ferrite in current LTO cartridges. Strontium sits on a row above Barium in the periodic table, indicating a much smaller atom. This enables for much smaller particles to be placed into tracks, and thankfully according to Fujifilm, Strontium Ferrite exhibits properties along the same lines as Barium Ferrite, but moreso, enabling higher performance while simultaneously increasing particle density. [...] Fujifilm states that 400 TB is the limit of Strontium Ferrite, indicating that new materials would be needed to go beyond. That said, we are talking about only 224 Gbit-per-square-inch for storage, which compared to mechanical hard disks going beyhind 1000 Gbit-per-square-inch today, there would appear to be plenty of room at the top if the technologies could converge.
