Microsoft has patented an AI-powered backpack design featuring a plethora of sensors that may include cameras, microphones, GPS, and a compass. Tom's Hardware reports: Additionally, Microsoft thinks it may be useful to add in LEDs and speakers, as well as a haptic actuator, into the straps. Some real-time processing is deemed necessary to the smart wearable. Thus, various recognition modules are proposed to provide image, text, speech, facial, and cognitive recognition. As well as real-time monitors feeding data to the built-in processing power for AI smarts, the system housed in the backpack also will boast a recording device (using on-board storage), wireless connectivity, battery power / charging and more.

With all the above sensing and processing on your person, in the backpack, it is envisioned that wearers will benefit from AI enhanced object identification and analysis, nearby device interaction, and be able to gain contextual insights. A flow chart shows how the backpack and its data feed might work alongside personal computers and cloud servers. Other illustrations show the wandering backpack wearer navigating a ski resort, and checking out supermarket prices, as well as considering booking concert tickets. Sometimes the user may interact with the backpack's on-board AI via speech, e.g. "Hey Backpack, add this poster to my calendar." Alternatively some AI actions or contextual tasks may be instigated by interacting with sensors on the straps. You can view the patent application here.

Dell and Samsung are the latest beneficiaries of the current frenzy of speculation surrounding anything AI related, with both vendors seeing a rise in share prices related to their future AI prospects. From a report: Shares in Dell were said to be up 8 percent in extended trading following the Round Rock company releasing its results for the second quarter of its financial year 2024. These showed that revenue was $22.9 billion, down 13 percent on the same period last year. However, this figure was also up 10 percent on the previous quarter, with the company attributing this growth to rising demand for AI-optimized servers, as well as its PowerStore and PowerFlex storage systems. AI accounted for 20 percent of server revenue in the first half of the year, Dell said.

Similarly, Dell said it is seeing growth in demand for its workstations designed to help organizations run complex AI workloads locally, with its commercial client revenue hitting $10.6 billion. This accounted for the lion's share of the Client Solutions Group second quarter revenue of $12.9 billion, which was down 16 percent year-on-year but up 8 percent on the last quarter. Dell vice chairman and chief operating officer Jeff Clarke said that the company continued to focus on the most profitable segments of the market where he claimed Dell has a leading position.

An anonymous reader shared this report from the New York: In 2017, Michael Moritz, a billionaire venture capitalist, sent a note to a potential investor about what he described as an unusual opportunity: a chance to invest in the creation of a new California city. The site was in a corner of the San Francisco Bay Area where land was cheap. Moritz and others had dreams of transforming tens of thousands of acres into a bustling metropolis that, according to the pitch, could generate thousands of jobs and be as walkable as Paris or the West Village in New York.

He painted a kind of urban blank slate where everything from design to construction methods and new forms of governance could be rethought. And it would all be a short distance from San Francisco and Silicon Valley... Since then, a company called Flannery Associates has been buying large plots of land in a largely agricultural region 60 miles northeast of San Francisco. The company, which has little information public about its operations, has committed more than $800 million to secure thousands of acres of farmland, court documents show. One parcel after another, Flannery made offers to every landowner for miles, paying several times the market rate, whether the land had been listed for sale or not...

Brian Brokaw, a representative for the investor group, said in a statement that the group was made up of "Californians who believe that Solano County's and California's best days are ahead." He said the group planned to start working with Solano County residents and elected officials, as well as with Travis Air Force Base, next week... The land that Flannery has been purchasing is not zoned for residential use, and even in his 2017 pitch, Moritz acknowledged that rezoning could "clearly be challenging" — a nod to California's notoriously difficult and litigious development process. To pull off the project, the company will almost certainly have to use the state's initiative system to get Solano County residents to vote on it. The hope is that voters will be enticed by promises of thousands of local jobs; increased tax revenue; and investments in infrastructure like parks, a performing arts center, shopping, dining and a trade school.
Moritz's 2017 email had argued their project "should relieve some of the Silicon Valley pressures we all feel — rising home prices, homelessness, congestion etc."

SFGate estimates the group now owns 52,000 acres — "an empire that is nearly double the size of the city of San Francisco" — and notes that some details emerged when the group filed a document to repond to a lawsuit. "It claims it told landowners that they could keep 'existing income streams from wind energy and natural gas storage,' could 'continue using these properties rent-free for decades,' and would receive 'significant grants from Flannery for charitable giving, to be used at the [landowners'] discretion to support local schools and other non-profits.'"

"Tech billionaires reportedly backing mysterious Solano County land grab," reads the headline on SFGate's latest article: SFGATE reported earlier this week that a survey had circulated to Solano County residents asking for their opinions on the potential development of "a new city with tens of thousands of new homes, a large solar energy farm, orchards with over a million new trees, and over ten thousand acres of new parks and open space."

"The green energy revolution still faces a huge obstacle: a lack of long-term, cost-efficient renewable storage," writes the Washington Post.

But then they check in on a Finnish start-up running the world's first commercial-scale sand battery, which uses solar panels and wind turbines to heat sand-filled vats (up to 1,000 degrees) to back up district heating networks: The sand can hold onto the power for weeks or months at a time — a clear advantage over the lithium ion battery, the giant of today's battery market, which usually can hold energy for only a number of hours.

Unlike fossil fuels, which can be easily transported and stored, solar and wind supplies fluctuate. Most of the renewable power that isn't used immediately is lost. The solution is storage innovation, many industry experts agree. In addition to their limited capacity, lithium ion batteries, which are used to power everything from mobile phones to laptops to electric vehicles, tend to fade with every recharge and are highly flammable, resulting in a growing number of deadly fires across the world. The extraction of cobalt, the lucrative raw material used in lithium ion batteries, also relies on child labor. U.N. agencies have estimated that 40,000 boys and girls work in the industry, with few safety measures and paltry compensation. These serious environmental and human rights challenges pose a problem for the electric vehicle industry, which requires a huge supply of critical minerals.

So investors are now pouring money into even bigger battery ventures. More than $900 million has been invested in clean storage technologies since 2021, up from $360 million the year before, according to the Long Duration Energy Storage Council, an organization launched after that year's U.N. climate conference to oversee the world's decarbonization. The group predicts that by 2040, large-scale, renewable energy storage investments could reach $3 trillion. That includes efforts to turn natural materials into batteries. Once-obscure start-ups, experimenting with once-humble commodities, are suddenly receiving millions in government and private funding. There's the multi-megawatt CO2 battery in Sardinia, a rock-based storage system in Tuscany, and a Swiss company that's moving massive bricks along a 230-foot tall building to store and generate renewable energy. One Danish battery start-up, which stores energy from molten salt, is sketching out plans to deploy power plants in decommissioned coal mines across three continents...

But in order to succeed, natural batteries will need to provide the same kind of steady power as fossil fuels, at scale. Whether that can be achieved remains to be seen, say energy experts. And the industry may be subject to the same pitfalls that loom over the renewables energy sector at large: Projects will need to be constructed from scratch, and they might only be adopted in developed countries that can afford such experimentation. Lovschall-Jensen, the CEO of a Danish molten salt-based storage start-up called Hyme, says the challenge will be maintaining the same standards to which the modern world has become accustomed: receiving power, on demand, with the flip of a switch.

He believes that natural batteries, though still in their infancy, can serve that goal.

An anonymous reader quotes a report from 404 Media: A buzzy startup offering financial infrastructure to crypto companies has found itself bankrupt primarily because it can't gain access to a physical crypto wallet with $38.9 million in it. The company also did not write down recovery phrases, locking itself out of the wallet forever in something it has called "The Wallet Event" to a bankruptcy judge. Prime Trust pitches itself as a crypto fintech company designed to help other startups offer crypto retirement plans, know-your-customer interfaces, ensure liquidity, and a host of other services. It says it can help companies build crypto exchanges, payment platforms, and create stablecoins for its clients. The company has not had a good few months. In June, the state of Nevada filed to seize control of the company because it was near insolvency. It was then ordered to cease all operations by a federal judge because it allegedly used customers' money to cover withdrawal requests from other companies.

The company filed for bankruptcy, and, according to a filing by its interim CEO, which you really should read in full, the company offers an "all-in-one solution for customers that remains unmatched in the marketplace." A large problem, among more run-of-the-mill crypto economy problems such as "lack of operational and spending oversight" and "regulatory issues," is the fact that it lost access to a physical wallet it was keeping a tens of millions of dollars in, and cannot get back into it. [...] For several years, the company then took customer deposits into this address, to the tune of tens of millions of dollars. In December, 2021, "when a customer requested a significant withdrawal of ETH that the company could not fulfill [from other wallets,]" it went to withdraw it from this hardware wallet. "It was around this time that they discovered that the Company did not have the Wallet Access Devices and thus, could not access the cryptocurrency stored in the 98f Wallet."

The company then, for several months, had to "use $76,367,247.90 in the aggregate to purchase ETH to fund customer withdrawals." The money stuck in the wallet is currently worth $38.9 million as of August 22, it claimed. It is worth mentioning that the company did not tell regulators or customers about this issue for months after it discovered the problem. The company has still not solved this issue: "The Company remains unable to access the 98f Wallet," it wrote. "The investigation continues." Prime Trust swears in its filing that this was an "aberrant" event and "extremely unlikely to occur again."

An anonymous reader quotes a report from Ars Technica: A federal judge yesterday granted Google's motion to dismiss a lawsuit filed by the Republican National Committee (RNC), which claims that Google intentionally used Gmail's spam filter to suppress Republicans' fundraising emails. An order (PDF) dismissing the lawsuit was issued yesterday by US District Judge Daniel Calabretta. The RNC is seeking "recovery for donations it allegedly lost as a result of its emails not being delivered to its supporters' inboxes," Calabretta noted. But Google correctly argued that the lawsuit claims are barred by Section 230 of the Communications Decency Act, the judge wrote. The RNC lawsuit was filed in October 2022 in US District Court for the Eastern District of California.

"While it is a close case, the Court concludes that... the RNC has not sufficiently pled that Google acted in bad faith in filtering the RNC's messages into Gmail users' spam folders, and that doing so was protected by Section 230. On the merits, the Court concludes that each of the RNC's claims fail as a matter of law for the reasons described below," he wrote. Calabretta, a Biden appointee, called it "concerning that Gmail's spam filter has a disparate impact on the emails of one political party, and that Google is aware of and has not yet been able to correct this bias." But he noted that "other large email providers have exhibited some sort of political bias" and that if Google did not filter spam, it would harm its users by subjecting them "to harmful malware or harassing messages. On the whole, Google's spam filter, though in this instance imperfect, is not morally blameworthy."

The RNC was given leave to amend another claim that alleged intentional interference with prospective economic relations under California law. The judge dismissed the claim as follows: "The RNC argues that Google's conduct was independently wrongful because '(1) it is political discrimination against the RNC, (2) it is dishonest to Google's users and the public, and (3) Google repeatedly lied about it.' As established above, political discrimination is not prohibited by California anti-discrimination laws and so Google's alleged discrimination would not be unlawful. The latter two reasons do not provide a 'determinable legal standard' under which the Court could find the conduct wrongful; they rest on a 'nebulous' theory of wrongfulness which other courts have rejected." The RNC "has failed to establish that Defendant's alleged interference constituted a separate, independently 'wrongful act' that would be an appropriate predicate offense" but "will be granted leave to amend this claim to establish that Defendant's conduct was unlawful by some legal measure," Calabretta wrote. Google said in a statement: "We welcome the Court's finding that there are no plausible allegations that Gmail's spam filters discriminate for political purposes. We will continue investing in spam-filtering technologies that protect people from unwanted emails while still allowing senders to reach the inboxes of users who want their messages."

Dropbox, a provider of online data storage, is ending its unlimited option, saying a small handful of customers were using massive amounts of resources that had the potential to degrade the cloud service for the rest of its clients. From a report: The company's highest-tier "all the space you need" storage plan will be capped at about 5 terabytes per user for new customers, the company said in a blog post.

While the plan was designed for businesses, some clients were instead using it for cryptocurrency mining, pooling storage with strangers, or re-selling the cloud service, Dropbox said. These uses "frequently consume thousands of times more storage than our genuine business customers, which risks creating an unreliable experience for all of our customers," the company said. [...] The change follows Alphabet's Google removing "as much storage as you need" product branding for its highest-tier Workspace plan in May, according to copies of its website hosted on the Wayback Machine.

Last week we wrote about a lawsuit against Western Digital that alleged that the firm's solid state drive didn't live up to its marketing promises. More lawsuits have been filed against the company since. ArsTechnica: On Thursday, two more lawsuits were filed against Western Digital over its SanDisk Extreme series and My Passport portable SSDs. That brings the number of class-action complaints filed against Western Digital to three in two days. In May, Ars Technica reported about customer complaints that claimed SanDisk Extreme SSDs were abruptly wiping data and becoming unmountable. Ars senior editor Lee Hutchinson also experienced this problem with two Extreme SSDs. Western Digital, which owns SanDisk, released a firmware update in late May, saying that currently shipping products weren't impacted. But the company didn't mention customer complaints of lost data, only that drives could "unexpectedly disconnect from a computer."

Further, last week The Verge claimed a replacement drive it received after the firmware update still wiped its data and became unreadable, and there are some complaints on Reddit pointing to recent problems with Extreme drives. All three cases filed against Western Digital this week seek class-action certification (Ars was told it can take years for a judge to officially state certification and that cases may proceed with class-wide resolutions possibly occurring before official certification). Ian Sloss, one of the lawyers representing Matthew Perrin and Brian Bayerl in a complaint filed yesterday, told Ars he doesn't believe class-action certification will be a major barrier in a case "where there is a common defect in the firmware that is consistent in all devices." He added that defect cases are "ripe for class treatment."

"Italian producers of parmesan cheese have been fighting against imitations for years," writes the Wall Street Journal, adding "Their latest trick to beat counterfeiters is edible microchips.

"Now, makers of Parmigiano-Reggiano, as the original parmesan cheese is officially called, are slapping the microchips on their 90-pound cheese wheels as part of an endless cat-and-mouse game between makers of authentic and fake products." New methods to guarantee the origin of products are being used across the EU. Some wineries are putting serial numbers, invisible ink and holograms on their bottles. So-called DNA fingerprinting of milk bacteria pioneered in Switzerland, which isn't in the EU, is now being tested inside the bloc as a method for identifying cheese. QR codes are also proliferating, including on individual portions of pre-sliced Prosciutto di San Daniele, a raw ham similar to Prosciutto di Parma. A smartphone can be used to show information such as how long the prosciutto has been aged and when it was sliced... The new silicon chips, made by Chicago-based p-Chip, use blockchain technology to authenticate data that can trace the cheese as far back as the producer of the milk used.

The chips have been in advanced testing on more than 100,000 Parmigiano wheels for more than a year. The consortium of producers wants to be sure the chips can stand up to Parmigiano's aging requirement, which is a minimum of one year and can exceed three years for some varieties... The p-Chips can withstand extreme heat or cold, can be read through ice and can withstand years of storage in liquid nitrogen. They have outperformed RFID chips, which are larger, can be more difficult to attach to products, are more fragile and can't survive extreme temperatures, according to p-Chip Chief Technology Officer Bill Eibon. Parmigiano producers also use QR codes, but the codes are easily copied and degrade during the cheese's aging process.

A robot heats the Parmigiano wheel's casein label — a small plaque made of milk protein that is widely used in the cheese industry — and then inserts the chip on top. A hand-held reader can grab the data from the chips, which cost a few cents each and are similar to the ones that some people have inserted under the skin of their pets. The chips can't be read remotely. In lab tests, the chips sat for three weeks in a mock-up of stomach acid without leaking any dangerous material. Eibon went a step further, eating one without suffering any ill effects, but he isn't touting that lest p-Chip face accusations it is tracking people, something that isn't possible because the chips can't be read remotely and can't be read once they are ingested.

"We don't want to be known as the company accused of tracking people," said Eibon. "I ate one of the chips and nobody is tracking me, except my wife, and she uses a different method."
Merck KGaA will soon be using the same chips, the article points out, and the chips "are also being tested in the automotive industry to guarantee the authenticity of car parts.

"The chips could eventually be used on livestock, crops or medicine stored in liquid nitrogen."

Amazon is adding a new charge for third-party sellers who ship their own products instead of paying for the company's fulfillment services. CNBC reports: Beginning Oct. 1, members of Amazon's Seller Fulfilled Prime program will pay the company a 2% fee on each product sold, according to a notice sent to merchants last week, which was viewed by CNBC. Previously, there was no such fee for sellers. "We're updating our requirements for Seller Fulfilled Prime to ensure that it provides customers a great and consistent Prime experience," the notice states. An Amazon spokesperson told CNBC in a statement that the company instituted a fee for SFP members due to the costs of developing and running the program.

The SFP program, launched in 2015, allows third-party merchants to sell their products with the Prime badge without paying for Amazon's fulfillment services, known as Fulfillment By Amazon. The SFP program hasn't attracted as many users as FBA has, given that sellers are expected to meet the company's Prime delivery standards, such as speedy shipping and weekend service. In June, Amazon reopened sign-ups for the invite-only program, after it suspended enrollment in SFP in 2019. The e-commerce giant also charges sellers a referral fee between 8% and 15% on each sale. Sellers may also pay for things like warehouse storage, packing and shipping, as well as advertising fees.

Western Digital was sued on Tuesday on behalf of a California resident who claims the solid state drive he bought from the manufacturer was defective and that the storage slinger shipped kit that didn't live up to its marketing promises. The Register reports: The complaint [PDF], filed in federal court in San Jose, California, where the storage giant is based, alleges the Western Digital SanDisk 2TB Extreme Pro SSD purchased by plaintiff Nathan Krum in May for $180 failed because of an undisclosed flaw, which also affects SanDisk Extreme Pro, Extreme Portable, Extreme Pro Portable, and WD My Passport SSD models since January 2023, it's claimed. The complaint [PDF], filed in federal court in San Jose, California, where the storage giant is based, alleges the Western Digital SanDisk 2TB Extreme Pro SSD purchased by plaintiff Nathan Krum in May for $180 failed because of an undisclosed flaw, which also affects SanDisk Extreme Pro, Extreme Portable, Extreme Pro Portable, and WD My Passport SSD models since January 2023, it's claimed.

The complaint asserts Western Digital customers "have widely reported drive failures and data loss." Krum, in his filing, believes Western Digital is aware of the problem and not doing enough about it. "The SanDisk Extreme Pro SSD hard drives, which are also sold under the WD My Passport brand, have a firmware issue that causes them to disconnect or become unreadable by computers," he claimed, adding that his drive was among those that stopped working as expected.

It is alleged the drives can break down in various ways, including randomly disconnecting from their host, which could result in information not being saved correctly or file-system corruption. In any case, people find they can no longer access their stored documents, making the SSDs worthless and useless, it is claimed. [...] Chris Cantrell, an attorney at Doyle Lowther LLP who is representing the plaintiffs, told The Register it's not yet clear how many SanDisk SSDs experienced data loss though there are more than a few people who share his client's experience. "While Western Digital appears to have attempted to fix the issue with a firmware update, it does not appear to have fixed the issue," Cantrell added. "This is what prompted us to file this lawsuit on behalf of affected SanDisk SSD purchasers. We anticipate adding additional named plaintiffs from other states over the next few weeks." The complaint alleges breach of contract, violation of consumer protection law, and misleading advertising, among other claims, and seeks damages, legal costs, and other relief.

What to make of the news that early research appears unable to duplicate the much-ballyhooed claims for the LK99 superconductor?

"The episode revealed the intense appetite in Silicon Valley for finding the next big thing," argues the Washington Post, "after years of hand-wringing that the tech world has lost its ability to come up with big, world-changing innovations, instead channeling all its money and energy into building new variations of social media apps and business software..." [M]any tech leaders are nervous that the current focus on consumer and business software has led to stagnation. A decade ago, investors prophesied that self-driving cars would take over the roads by the mid-2020s — but they are still firmly in the testing phase, despite billions of dollars of investment. Cryptocurrencies and blockchain technology have had multiple hype cycles of their own, but have yet to fundamentally change any industry, besides crime and money laundering. Tech meant to help mitigate climate change, like carbon capture and storage, has lagged without major advances in years. Meanwhile, Big Tech companies used their huge cash hoards to snap up smaller competitors, with antitrust regulators only recently beginning to clamp down on consolidation. Over the last year, as higher interest rates have cut into the amount of venture capital and slowing growth has caused companies to pull back spending, a massive wave of layoffs has swept the industry, and companies such as Google that previously said they'd invest some of their profits in big, risky ideas have turned away from such "moonshots..."

Room-temperature superconductors would be especially relevant to the tech industry right now, which is busy burning billions of dollars on new computer chips and the energy costs to run them to train the AI models behind tools like ChatGPT and Google's Bard. For years, computer chips have gotten smaller and more efficient, but that progress has run up against the limits of the physical world as transistors get so small some are now just one atom thick.

Last year, Queens resident David Leacraft filed a lawsuit against Canon claiming that his Canon Pixma All-in-One printer won't scan documents unless it has ink. According to The Verge's Sean Hollister, it has quietly ended in a private settlement rather than becoming a big class-action. From the report: I just checked, and a judge already dismissed David Leacraft's lawsuit in November, without (PDF) Canon ever being forced to show what happens when you try to scan without a full ink cartridge. (Numerous Canon customer support reps wrote that it simply doesn't work.) Here's the good news: HP, an even larger and more shameless manufacturer of printers, is still possibly facing down a class-action suit for the same practice.

As Reuters reports, a judge has refused to dismiss a lawsuit by Gary Freund and Wayne McMath that alleges many HP printers won't scan or fax documents when their ink cartridges report that they've run low. Among other things, HP tried to suggest that Freund couldn't rely on the word of one of HP's own customer support reps as evidence that HP knew about the limitation. But a judge decided it was at least enough to be worth exploring in court. "Plaintiffs have plausibly alleged that HP had a duty to disclose and had knowledge of the alleged defect," wrote Judge Beth Labson Freeman, in the order denying almost all of HP's current attempts to dismiss the suit.

Interestingly, neither Canon nor HP spent any time trying to argue their printers do scan when they're low on ink in the lawsuit responses I've read. Perhaps they can't deny it? Epson, meanwhile, has an entire FAQ dedicated to reassuring customers that it hasn't pulled that trick since 2008. (Don't worry, Epson has other forms of printer enshittification.) HP does seem to be covering its rear in one way. The company's original description on Amazon for the Envy 6455e claimed that you could scan things "whenever". But when I went back now to check the same product page, it now reads differently: HP no longer claims this printer can scan "whenever" you want it to. Now, we wait to see whether the case can clear the bars needed to potentially become a big class-action trial, or whether it similarly settles like Canon, or any number of other outcomes.

SanDisk's silence this week has been deafening. Its portable SSDs are being lambasted as users and tech publications call for them to be pulled. From a report: The recent scrutiny of the drives follows problems from this spring when users, including an Ars Technica staff member, saw Extreme-series portable SSDs wipe data and become unmountable. A firmware update was supposed to fix things, but new complaints dispute its effectiveness. SanDisk has stayed mum on recent complaints and hasn't explained what caused the problems.

In May, Ars Technica reported on SanDisk Extreme V2 and Extreme Pro V2 SSDs wiping data before often becoming unreadable to the user's system. At least four months of complaints had piled up by then, including on SanDisk's forums and all over Reddit. Even Ars' Lee Hutchinson fell victim to the faulty drives. Two whole Extreme Pros died on him. Both times they filled about 50 percent and then showed a bunch of read and write errors. Upon disconnecting and reconnecting, the drive was unformatted and wiped, and he could not fix either drive by wiping and reformatting. When Ars reached out to SanDisk about the problem in May, it didn't answer most of our questions about why these problems happened (and, oddly, excluded certain models we saw affected when naming which models were affected).

Long-time Slashdot reader KindMind shares a report from The Register: Researchers at MIT claim to have found a novel new way to store energy using nothing but cement, a bit of water, and powdered carbon black -- a crystalline form of the element. The materials can be cleverly combined to create supercapacitors, which could in turn be used to build power-storing foundations of houses, roadways that could wirelessly charge vehicles, and serve as the foundation of wind turbines and other renewable energy systems -- all while holding a surprising amount of energy, the team claims. According to a paper published in the Proceedings of the National Academy of Sciences, 45 cubic meters of the carbon-black-doped cement could have enough capacity to store 10 kilowatt-hours of energy -- roughly the amount an average household uses in a day. A block of cement that size would measure about 3.5 meters per side and, depending on the size of the house, the block could theoretically store all the energy an off-grid home using renewables would need." [...]

Just three percent of the mixture has to be carbon black for the hardened cement to act as a supercapacitor, but the researchers found that a 10 percent carbon black mixture appears to be ideal. Beyond that ratio, the cement becomes less stable -- not something you want in a building or foundation. The team notes that non-structural use could allow higher concentrations of carbon black, and thus higher energy storage capacity. The team has only built a tiny one-volt test platform using its carbon black mix, but has plans to scale up to supercapacitors the same size as a 12-volt automobile battery -- and eventually to the 45 cubic meter block. Along with being used for energy storage, the mix could also be used to provide heat -- by applying electricity to the conductive carbon network encased in the cement, MIT noted.
As Science magazine puts it, "Tesla's Powerwall, a boxy, wall-mounted, lithium-ion battery, can power your home for half a day or so. But what if your home was the battery?"

For over a decade, Backblaze's quarterly reports on the annualized failure rates (AFRs) of its substantial hard disk drives inventory have offered a peek into long-term storage utilization. The company, known for its backup and cloud storage services, has now disclosed data for the second quarter of 2023, revealing a fascinating rise in AFRs. ArsTechnica: Today's blog post details data for 240,940 HDDs that Backblaze uses for data storage around the world. There are 31 different models, and Backblaze's Andy Klein, who authored the blog, estimated in an email to Ars Technica that 15 percent of the HDDs in the dataset, including some of the 4, 6, and 8TB drives, are consumer-grade. The dataset doesn't include boot drives, drives in commission for testing purposes, or drive models for which Backblaze didn't have at least 60 units. One of the biggest revelations from examining the drives from April 1, 2023, through June 30, 2023, was an increase in AFR from Q1 2023 (1.54 percent) to Q2 2023 (2.28 percent). Backblaze's Q1 dataset examined 237,278 HDDs across 30 models. Of course, that AFR increase alone isn't enough to warrant any panic.

Since quarterly AFR numbers are "volatile," Klein told Ars Technica, Backblaze further evaluates both quarter-to-quarter and lifetime trends "to see if what happened was an anomaly or something more." So, Klein started digging further by grouping the drives by capacity. This is because, as Klein explained to Ars: "A Backblaze storage vault consists of 1,200 drives of the same size, with 60 drives in 20 storage servers. If we grouped the drives strictly by age and wanted to replace just the oldest drives in a given Backblaze vault, we would only replace those drives in the vault that met the old age criteria, not all the drives. Then, a year from now, we'd do it again, and the year after that, etc. By using the average age by drive size, we can, as appropriate, replace/upgrade all of the drives in a vault at once."

An anonymous reader quotes a report from Ars Technica: Film companies lost another attempt to force Reddit to identify anonymous users who discussed piracy. A federal court on Saturday quashed a subpoena (PDF) demanding users' names and other identifying details, agreeing with Reddit's argument that the film companies' demands violate the First Amendment. The plaintiffs are 20 producers of popular movies who are trying to prove that Internet service provider Grande is liable for its subscribers' copyright infringement because the ISP allegedly ignores piracy on its network. Reddit isn't directly involved in the copyright case. But the film companies filed a motion to compel Reddit to respond to a subpoena demanding "basic account information including IP address registration and logs from 1/1/2016 to present, name, email address and other account registration information" for six users who wrote comments on Reddit threads in 2011 and 2018.

"The issue is whether that discovery is permissible despite the users' right to speak anonymously under the First Amendment," US Magistrate Judge Laurel Beeler wrote in her ruling against the film copyright holders. "The court denies the motion because the plaintiffs have not demonstrated a compelling need for the discovery that outweighs the users' First Amendment right to anonymous speech." The film companies seeking Reddit users' identities include After II Movie LLC, Bodyguard Productions, Hitman 2 Productions, Millennium Funding, Nikola Productions, Rambo V Productions, and Dallas Buyers Club LLC. As Beeler's ruling on Saturday noted, they sought the identities of two users who wrote about torrenting on Grande's network in 2018 [...]. The companies also sought identities of four users who commented in a 2011 thread. "I have grande. No issues with torrent or bandwidth caps," one user comment said. Another Reddit user wrote, "I have torrented like a motherfucker all over grande and have never seen anything." Reddit's filing (PDF) pointed out that the statute of limitations for copyright infringement is three years. The film companies said (PDF) the statute of limitations is irrelevant to whether the comments can provide evidence in the case against Grande.

"A significant swath of our downtown office space is sitting empty," writes a columnist for the Guardian. "New York, Chicago, Atlanta, Los Angeles, Denver, Philadelphia, San Francisco, Houston, Dallas and other big cities are experiencing record-high office vacancies as workers keep working from home and companies keep letting them..." Some face-time is necessary but we're never going to go back to a 100% in-the-office policy, and companies that attempt this will lose talent to those that adapt to the shift. All this means that a substantial amount of square feet in all those tall office buildings in our major metropolitan areas are going to remain empty. The owners of these properties are already feeling the pressure of meeting higher debt maintenance with lower lease revenue, with many facing default. Countless small businesses in downtown areas facing significantly less traffic are closing their doors. And unless something is done, those empty buildings — after the banks have repossessed them from bankrupt borrowers — will become derelict, inviting even more crime and homelessness. It's already happening.

So what to do? The good news is that there are many opportunities for the entrepreneurial.

For example, existing office floors can be turned into less expensive single units for startups and incubators who want to boast a downtown address. Some buildings in cities with a vibrant and residential downtown — like Philadelphia — could be turned into residences. Others that are burdened with older, unsafe, non-air-conditioned school structures could convert this space into classrooms for students. Or perhaps all the homeless people sleeping on the streets outside of these empty structures could be given a warm place to stay with medical and counselling support?

With the continuing boom in e-commerce, warehouse space remains costly but could become more affordable — and logistically accessible — in a downtown structure. Manufacturing space could be more accommodating, with a better location making it easier to procure workers. Other alternatives for these buildings already being considered include vertical farming, storage facilities, gyms and movie sets. Or what about taking the red pill and merely knocking these buildings down and creating open spaces, parks, museums or structures that are more amenable to this new era of downtown life?

Slashdot reader AndrewZX quotes Ars Technica: Mainframe computers are often seen as ancient machines—practically dinosaurs. But mainframes, which are purpose-built to process enormous amounts of data, are still extremely relevant today. If they're dinosaurs, they're T-Rexes, and desktops and server computers are puny mammals to be trodden underfoot.

It's estimated that there are 10,000 mainframes in use today. They're used almost exclusively by the largest companies in the world, including two-thirds of Fortune 500 companies, 45 of the world's top 50 banks, eight of the top 10 insurers, seven of the top 10 global retailers, and eight of the top 10 telecommunications companies. And most of those mainframes come from IBM.

In this explainer, we'll look at the IBM mainframe computer -- what it is, how it works, and why it's still going strong after over 50 years.
"Today's mainframe can have up to 240 server-grade CPUs, 40TB of error-correcting RAM, and many petabytes of redundant flash-based secondary storage. They're designed to process large amounts of critical data while maintaining a 99.999 percent uptime -- that's a bit over five minutes' worth of outage per year..."

"RAM, CPUs, and disks are all hot-swappable, so if a component fails, it can be pulled and replaced without requiring the mainframe to be powered down."

Friday America's Department of Energy announced plans to re-purpose some of the land it owns — "portions of which were previously used in the nation's nuclear weapons program" — for generating clean energy. They'll be leasing them out for "utility-scale clean energy projects" in an initiative called "Cleanup to Clean Energy."

The agency has identified 70,000 acres for potential development, in New Mexico, Nevada, South Carolina, Idaho, and Washington: "We are going to transform the lands we have used over decades for nuclear security and environmental remediation by working closely with tribes and local communities together with partners in the private sector to build some of the largest clean energy projects in the world," said U.S. Secretary of Energy Jennifer M. Granholm. "Through the Cleanup to Clean Energy initiative, the Department of Energy will leverage areas that were previously used to protect our national security and will repurpose them to the same end — this time, generating clean energy that will help save the planet and protect our energy independence."
The announcement notes that in December 2021, President Biden directed U.S. federal agencies to "authorize use of their real property assets, including land for the development of new clean electricity generation and storage through leases, grants, permits, or other mechanisms."

"As the leading Federal agency on clean energy research and development, DOE has both a unique opportunity and a clear responsibility to lead by example and identify creative solutions to achieve the President's mandate."
