Researchers believe they've discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging and discharging. The new find needs optimization but has the potential to help power electric vehicles. * An anonymous reader shared this report from Popular Mechanics: In a study published in Science, lead author Sang-Hoon Bae, an assistant professor of mechanical engineering and materials science, demonstrates a novel heterostructure that curbs energy loss, enabling capacitors to store more energy and charge rapidly without sacrificing durability... Within capacitors, ferroelectric materials offer high maximum polarization. That's useful for ultra-fast charging and discharging, but it can limit the effectiveness of energy storage or the "relaxation time" of a conductor. "This precise control over relaxation time holds promise for a wide array of applications and has the potential to accelerate the development of highly efficient energy storage systems," the study authors write.

Bae makes the change — one he unearthed while working on something completely different — by sandwiching 2D and 3D materials in atomically thin layers, using chemical and nonchemical bonds between each layer. He says a thin 3D core inserts between two outer 2D layers to produce a stack that's only 30 nanometers thick, about 1/10th that of an average virus particle... The sandwich structure isn't quite fully conductive or nonconductive.

This semiconducting material, then, allows the energy storage, with a density up to 19 times higher than commercially available ferroelectric capacitors, while still achieving 90 percent efficiency — also better than what's currently available.

An anonymous reader shared this report from the Register: The co-author of SQL, the standardized query language for relational databases, has come out in support of the NoSQL database movement that seeks to escape the tabular confines of the RDBMS. Speaking to The Register as SQL marks its 50th birthday, Donald Chamberlin, who first proposed the language with IBM colleague Raymond Boyce in a 1974 paper [PDF], explains that NoSQL databases and their query languages could help perform the tasks relational systems were never designed for. "The world doesn't stay the same thing, especially in computer science," he says. "It's a very fast, evolving, industry. New requirements are coming along and technology has to change to meet them, I think that's what's happening. The NoSQL movement is motivated by new kinds of applications, particularly web applications, that need massive scalability and high performance. Relational databases were developed in an earlier generation when scalability and performance weren't quite as important. To get the scalability and performance that you need for modern apps, many systems are relaxing some of the constraints of the relational data model."

[...] A long-time IBMer, Chamberlin is now semi-retired, but finds time to fulfill a role as a technical advisor for NoSQL company Couchbase. In the role, he has become an advocate for a new query language designed to overcome the "impedance mismatch" between data structures in the application language and a database, he says. UC San Diego professor Yannis Papakonstantinou has proposed SQL++ to solve this problem, with a view to addressing impedance mismatch between heavily object-based JavaScript, the core language for web development and the assumed relational approach embedded in SQL. Like C++, SQL++ is designed as a compatible extension of an earlier language, SQL, but is touted as better able to handle the JSON file format inherent in JavaScript. Couchbase and AWS have adopted the language, although the cloud giant calls it PartiQL.
At the end of the interview, Chamblin adds that "I don't think SQL is going to go away. A large part of the world's business data is encoded in SQL, and data is very sticky. Once you've got your database, you're going to leave it there. Also, relational systems do a very good job of what they were designed to do...

"[I]f you're a startup company that wants to sell shoes on the web or something, you're going to need a database, and one of those SQL implementations will do the job for free. I think relational databases and the SQL language will be with us for a long time."

An anonymous reader shared this report from CNN: The "world's largest" plant designed to suck planet-heating pollution out of the atmosphere like a giant vacuum began operating in Iceland on Wednesday. "Mammoth" is the second commercial direct air capture plant opened by Swiss company Climeworks in the country, and is 10 times bigger than its predecessor, Orca, which started running in 2021... Climeworks plans to transport the carbon underground where it will be naturally transformed into stone, locking up the carbon permanently... The whole operation will be powered by Iceland's abundant, clean geothermal energy....

Climeworks started building Mammoth in June 2022, and the company says it is the world's largest such plant. It has a modular design with space for 72 "collector containers" — the vacuum parts of the machine that capture carbon from the air — which can be stacked on top of each other and moved around easily. There are currently 12 of these in place with more due to be added over the next few months. Mammoth will be able to pull 36,000 tons of carbon from the atmosphere a year at full capacity, according to Climeworks. That's equivalent to taking around 7,800 gas-powered cars off the road for a year...

All the carbon removal equipment in the world is only capable of removing around 0.01 million metric tons of carbon a year, a far cry from the 70 million tons a year needed by 2030 to meet global climate goals, according to the International Energy Agency [7,000x more]... Jan Wurzbacher, the company's co-founder and co-CEO, said Mammoth is just the latest stage in Climeworks' plan to scale up to 1 million tons of carbon removal a year by 2030 and 1 billion tons by 2050. Plans include potential DAC plants in Kenya and the United States.

Slashdot reader quonset writes: The last floppy disk was manufactured in 2011. Despite no new supplies being available for over a decade, there are still people, and organizations, who rely on floppy disks. Each has their own story as to why they rely on what is essentially 1970s technology.
From the BBC: Tom Persky, a US businessman, has been selling "new", as in, unopened, floppy disks for years and still finds the trade lucrative. He runs Floppydisk.com, which offers disks for about US$1 (£0.80) each, though some higher capacity versions cost up to US$10 (£8) per disk, he says. Persky has customers all over the world and you could split them roughly 50-50 into hobbyists and enthusiasts like Espen Kraft on one side, and industrial users on the other. This latter category encompasses people who use computers at work that require floppy disks to function. They are, essentially, locked in to a format that the rest of the world has largely forgotten.

"I sell thousands of floppy disks to the airline industry, still," says Persky. He declines to elaborate. "Companies are not happy about when I talk about them." But it is well-known that some Boeing 747s, for example, use floppy disks to load critical software updates into their navigation and avionics computers. While these older aircraft might not be so common in Europe or the US these days, you might find one in the developing world, for instance, Persky hints. There are also pieces of factory equipment, government systems — or even animatronic figures — that still rely on floppy disks.

And in San Francisco, the Muni Metro light railway, which launched in 1980, won't start up each morning unless the staff in charge pick up a floppy disk and slip it into the computer that controls the railway's Automatic Train Control System, or ATCS. "The computer has to be told what it's supposed to do every day," explains a spokesman for the San Francisco Municipal Transport Agency (SFMTA). "Without a hard drive, there is nowhere to install software on a permanent basis."

This computer has to be restarted in such a way repeatedly, he adds — it can't simply be left on, for fear of its memory degrading.
The article also includes this quote from a cybersecurity expert at Pen Test Partners. "If floppy was the only interface, the only way to get malware on to [the computer] would be via said floppy disk. That's quite a limiting factor for the attacker..."

"Atmospheric levels of planet-warming carbon dioxide aren't just on their way to yet another record high this year," reports the Washington Post.

"They're rising faster than ever, according to the latest in a 66-year-long series of observations." Carbon dioxide levels were 4.7 parts per million higher in March than they were a year earlier, the largest annual leap ever measured at the National Oceanic Atmospheric Administration laboratory atop a volcano on Hawaii's Big Island. And from January through April, CO2 concentrations increased faster than they have in the first four months of any other year...

For decades, CO2 concentrations at Mauna Loa in the month of May have broken previous records. But the recent acceleration in atmospheric CO2, surpassing a record-setting increase observed in 2016, is perhaps a more ominous signal of failing efforts to reduce global greenhouse gas emissions and the damage they cause to Earth's climate. "Not only is CO2 still rising in the atmosphere — it's increasing faster and faster," said Arlyn Andrews, a climate scientist at NOAA's Global Monitoring Laboratory in Boulder, Colorado. A historically strong El Niño climate pattern that developed last year is a big reason for the spike. But the weather pattern only punctuated an existing trend in which global carbon emissions are rising even as U.S. emissions have declined and the growth in global emissions has slowed. The spike is "not surprising," said Ralph Keeling, director of the CO2 Program at Scripps Institution, "because we're also burning more fossil fuel than ever...."

El Niño-linked droughts in tropical areas including Indonesia and northern South America mean less carbon storage within plants, Keeling said. Land-based ecosystems around the world tend to give off more carbon dioxide during El Niño because of the changes in precipitation and temperature the weather pattern brings, Andrews added. And for CO2 concentrations to fall back below 400 parts per million, it would take more than two centuries even if emissions dropped close to zero by the end of this century, she added.
This year's reading "is more than 50 percent above preindustrial levels and the highest in at least 4.3 million years, according to NOAA."

A "one-of-a-kind" Google Cloud "misconfiguration" resulted in the deletion of UniSuper's account last week, disrupting the financial services provider's more than half a million members. "Services began being restored for UniSuper customers on Thursday, more than a week after the system went offline," reports The Guardian. "Investment account balances would reflect last week's figures and UniSuper said those would be updated as quickly as possible." From the report: The UniSuper CEO, Peter Chun, wrote to the fund's 620,000 members on Wednesday night, explaining the outage was not the result of a cyber-attack, and no personal data had been exposed as a result of the outage. Chun pinpointed Google's cloud service as the issue. In an extraordinary joint statement from Chun and the global CEO for Google Cloud, Thomas Kurian, the pair apologized to members for the outage, and said it had been "extremely frustrating and disappointing." They said the outage was caused by a misconfiguration that resulted in UniSuper's cloud account being deleted, something that had never happened to Google Cloud before.

While UniSuper normally has duplication in place in two geographies, to ensure that if one service goes down or is lost then it can be easily restored, because the fund's cloud subscription was deleted, it caused the deletion across both geographies. UniSuper was able to eventually restore services because the fund had backups in place with another provider. "Google Cloud CEO, Thomas Kurian has confirmed that the disruption arose from an unprecedented sequence of events whereby an inadvertent misconfiguration during provisioning of UniSuper's Private Cloud services ultimately resulted in the deletion of UniSuper's Private Cloud subscription," the pair said. "This is an isolated, 'one-of-a-kind occurrence' that has never before occurred with any of Google Cloud's clients globally. This should not have happened. Google Cloud has identified the events that led to this disruption and taken measures to ensure this does not happen again."

The Pixel 8A is officially here. The 8A gets Google's latest processor, adds a bunch of new AI features, and still starts at $499 in the US. But the very best news is that the 8A adopts the Pixel 8 and 8 Pro's seven years of software support, which is just unheard of in a midrange phone. From a report: The 8A retains the same general shape and size as its predecessor. But its 6.1-inch screen gets a couple of significant updates: the top refresh rate is now 120Hz, up from 90Hz, and the panel gets up to 40 percent brighter, up to 2,000 nits in peak brightness mode. They're important upgrades, especially since the 8A's main competition in the US, the OnePlus 12R, comes with an excellent display.

It comes with the same generative AI photo and video features that made a splash on the Pixel 8 and 8 Pro, including Best Take, Magic Editor, and Audio Magic Eraser. Circle to Search is also available, and the 8A will be able to run Google's mobile-optimized on-device AI model, Gemini Nano. As on the Pixel 8, it'll be a developer option delivered via feature drop. Other specs are either unchanged or slightly boosted compared to the last generation. There's still 8GB of RAM and 128GB of storage, though there's now a 256GB option. Camera hardware is unchanged from the 7A, including a stabilized 64-megapixel main sensor. There's an IP67 rating, consistent with the 7A, and battery capacity is a little higher at 4,492mAh compared to 4,385mAh. Wireless charging is available via Qi 1.3 at up to 7.5W -- no Qi2 here.

Apple revealed its refreshed iPad Pro lineup at its "Let Loose" virtual event Tuesday, featuring a slimmer design, OLED displays, and the company's latest M4 chip. The new 13-inch and 11-inch models boast enhanced brightness, color saturation, and contrast, with the 13-inch model measuring just 5.1 millimeters thick, making it Apple's thinnest device ever.

The M4 chip, which powers the new iPad Pros, delivers a 50% faster CPU and improved efficiency compared to the previous-gen M2 chip. Apple has also introduced updated accessories, including a redesigned Magic Keyboard with an aluminum palm rest and function key row, and the Apple Pencil Pro with squeeze gestures, Find My location tracking, and haptic feedback. The switch to OLED technology ensures consistent display quality across both iPad Pro sizes, addressing the previous disparity between the 12.9-inch Mini LED model and the smaller, traditional-screen version.

The base storage for both models is now 256GB, with prices starting at $999 for the 11-inch and $1,299 for the 13-inch. Both are available for preorder today and will be available in stores next week.

Swedish energy company Stockholm Exergi and Microsoft have announced a 10-year deal that will provide the tech giant with more than 3.3 million tons of carbon removal certificates through bioenergy with carbon capture and storage. While the value of the deal was not disclosed, it stands as the largest of its kind globally. Carbon Herald reports: Scheduled to commence in 2028 and span a decade, the agreement underscores a pivotal moment in combatting climate change. Anders Egelrud, CEO of Stockholm Exergi, lauded the deal as a "huge step" for the company and its BECCS project, emphasizing its profound implications for climate action. "I believe the agreement will inspire corporations with ambitious climate objectives, and we target to announce more deals with other pioneering companies over the coming months," he said. Recognizing the imperative of permanent carbon removals in limiting global warming to 1.5C or below, the deal aligns with Microsoft's ambitious goal of becoming carbon negative by 2030.

"Leveraging existing biomass power plants is a crucial first step to building worldwide carbon removal capacity," Brian Marrs, Microsoft's Senior Director of Energy & Carbon Removal, said, highlighting the importance of sustainable biomass sourcing for BECCS projects, as is the case with Stockholm Exergi. The partners will adhere to stringent quality standards, ensuring transparent reporting and adherence to sustainability criteria. The BECCS facility, once operational, will remove up to 800,000 tons of carbon dioxide (CO2) annually, contributing significantly to atmospheric carbon reduction. With environmental permits secured and construction set to commence in 2025, Stockholm Exergi plans to reach the final investment decision by the end of the year.

Markos Moulitsas is the poll-watching founder of the political blog Daily Kos. Thursday he wrote that in 2021, future third-party presidential candidate RFK Jr. had sued their web site.

"Things are not going well for him." Back in 2021, Robert F. Kennedy Jr. sued Daily Kos to unmask the identity of a community member who posted a critical story about his dalliance with neo-Nazis at a Berlin rally. I updated the story here, here, here, here, and here.

To briefly summarize, Kennedy wanted us to doxx our community member, and we stridently refused.
The site and the politician then continued fighting for more than three years. "Daily Kos lost the first legal round in court," Moulitsas posted in 2021, "thanks to a judge who is apparently unconcerned with First Amendment ramifications given the chilling effect of her ruling."

But even then, Moulitsas was clear on his rights: Because of Section 230 of the Communications Decency Act, [Kennedy] cannot sue Daily Kos — the site itself — for defamation. We are protected by the so-called safe harbor. That's why he's demanding we reveal what we know about "DowneastDem" so they can sue her or him directly.
Moulitsas also stressed that his own 2021 blog post was "reiterating everything that community member wrote, and expanding on it. And so instead of going after a pseudonymous community writer/diarist on this site, maybe Kennedy will drop that pointless lawsuit and go after me... consider this an escalation." (Among other things, the post cited a German-language news account saying Kennedy "sounded the alarm concerning the 5G mobile network and Microsoft founder Bill Gates..." Moulitsas also noted an Irish Times article which confirmed that at the rally Kennedy spoke at, "Noticeable numbers of neo-Nazis, kitted out with historic Reich flags and other extremist accessories, mixed in with the crowd.")

So what happened? Moulitsas posted an update Thursday: Shockingly, Kennedy got a trial court judge in New York to agree with him, and a subpoena was issued to Daily Kos to turn over any information we might have on the account. However, we are based in California, not New York, so once I received the subpoena at home, we had a California court not just quash the subpoena, but essentially signal that if New York didn't do the right thing on appeal, California could very well take care of it.

It's been a while since I updated, and given a favorable court ruling Thursday, it's way past time to catch everyone up.
New York is one of the U.S. states that doesn't have a strict "Dendrite standard" law protecting anonymous speech. But soon the blog founder discovered he had allies: The issues at hand are so important that The New York Times, the E.W.Scripps Company, the First Amendment Coalition, New York Public Radio, and seven other New York media companies joined the appeals effort with their own joint amicus brief. What started as a dispute over a Daily Kos diarist has become a meaningful First Amendment battle, with major repercussions given New York's role as a major news media and distribution center.

After reportedly spending over $1 million on legal fees, Kennedy somehow discovered the identity of our community member sometime last year and promptly filed a defamation suit in New Hampshire in what seemed a clumsy attempt at forum shopping, or the practice of choosing where to file suit based on the belief you'll be granted a favorable outcome. The community member lives in Maine, Kennedy lives in California, and Daily Kos doesn't publish specifically in New Hampshire. A perplexed court threw out the case this past February on those obvious jurisdictional grounds....

Then, last week, the judge threw out the appeal of that decision because Kennedy's lawyer didn't file in time — and blamed the delay on bad Wi-Fi...

Kennedy tried to dismiss the original case, the one awaiting an appellate decision in New York, claiming it was now moot. His legal team had sued to get the community member's identity, and now that they had it, they argued that there was no reason for the case to continue. We disagreed, arguing that there were important issues to resolve (i.e., Dendrite), and we also wanted lawyer fees for their unconstitutional assault on our First Amendment rights...

On Thursday, in a unanimous decision, a four-judge New York Supreme Court appellate panel ordered the case to continue, keeping the Dendrite issue alive and also allowing us to proceed in seeking damages based on New York's anti-SLAPP law, which prohibits "strategic lawsuits against public participation."
Thursday's blog post concludes with this summation. "Kennedy opened up a can of worms and has spent millions fighting this stupid battle. Despite his losses, we aren't letting him weasel out of this."

Natron Energy, a pioneer in sodium-ion battery technology, has officially commenced mass production of its lithium-free sodium batteries in its Holland, Michigan facility, offering an alternative energy storage solution with benefits such as faster cycling, longer lifespan, and safer usage compared to lithium-ion batteries. New Atlas reports: Not only is sodium somewhere between 500 to 1,000 times more abundant than lithium on the planet we call Earth, sourcing it doesn't necessitate the same type of earth-scarring extraction. Even moving beyond the sodium vs lithium surname comparison, Natron says its sodium-ion batteries are made entirely from abundantly available commodity materials that also include aluminum, iron and manganese. Furthermore, the materials for Natron's sodium-ion chemistry can be procured through a reliable US-based domestic supply chain free from geopolitical disruption. The same cannot be said for common lithium-ion materials like cobalt and nickel.

Sodium-ion tech has received heightened interest in recent years as a more reliable, potentially cheaper energy storage medium. While its energy density lags behind lithium-ion, advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative, especially for stationary uses like data center and EV charger backup storage. [...] Natron says its batteries charge and discharge at rates 10 times faster than lithium-ion, a level of immediate charge/discharge capability that makes the batteries a prime contender for the ups and downs of backup power storage. Also helping in that use case is an estimated lifespan of 50,000 cycles.

An anonymous reader quotes a report from Bloomberg: Dropbox said its digital-signature product, Dropbox Sign, was breached by hackers, who accessed user information including emails, user names and phone numbers. The software company said it became aware of the cyberattack on April 24, sought to limit the incident and reported it to law enforcement and regulatory authorities. "We discovered that the threat actor had accessed data related to all users of Dropbox Sign, such as emails and user names, in addition to general account settings," Dropbox said Wednesday in a regulatory filing. "For subsets of users, the threat actor also accessed phone numbers, hashed passwords, and certain authentication information such as API keys, OAuth tokens, and multi-factor authentication."

Dropbox said there is no evidence hackers obtained user accounts or payment information. The company said it appears the attack was limited to Dropbox Sign and no other products were breached. The company didn't disclose how many customers were affected by the hack. The hack is unlikely to have a material impact on the company's finances, Dropbox said in the filing. The shares declined about 2.5% in extended trading after the cyberattack was disclosed and have fallen 20% this year through the close.

"In less than 15 years, battery costs have fallen by more than 90%," according to a new report from the International Energy Agency, "one of the fastest declines ever seen in clean energy technologies."

And it's expected to get even cheaper, reports Reuters: An expected sharp fall in battery costs for energy storage in coming years will accelerate the shift to renewable energy from fossil fuels, the International Energy Agency (IEA) said on Thursday... The total capital costs of battery storage are due to tumble by up to 40% by 2030, the Paris-based watchdog said in its Batteries and Secure Energy Transitions report.

"The combination of solar PV (photovoltaic) and batteries is today competitive with new coal plants in India," said IEA Executive Director Fatih Birol. "And just in the next few years, it will be cheaper than new coal in China and gas-fired power in the United States. Batteries are changing the game before our eyes." [...] The global market for energy storage doubled last year to over 90 gigawatt-hours (GWh), the report said...

The slide in battery costs will also help provide electricity to millions of people without access, cutting by nearly half the average electricity costs of mini-grids with solar PV coupled with batteries by 2030, the IEA said.
The Los Angeles Times notes one place adopting the tech is California: Standing in the middle of a solar farm in Yolo County, [California governor] Newsom announced the state now had battery storage systems with the capacity of more than 10,000 megawatts — about 20% of the 52,000 megawatts the state says is needed to meet its climate goals.
Although Newsom acknowledged it isn't yet enough to eliminate blackouts...

That's the amount of storage reported by users of the Ceph storage solution (across more than 3,000 Ceph clusters).

The Ceph Foundation is a "directed fund" of the Linux Foundation, providing a neutral home for Ceph, "the most popular open source storage solution for modern data storage challenges" (offering an architecture that's "highly scalable, resilient, and flexible"). It's a software-defined storage platform, providing object storage, block storage, and file storage built on a common distributed cluster foundation.

And Friday they announced the release of Ceph Squid, "which comes with several performance and space efficiency features along with enhanced protocol support." Ceph has solidified its position as the cornerstone of open source data storage. The release of Ceph Squid represents a significant milestone toward providing scalable, reliable, and flexible storage solutions that meet the ever-evolving demands of digital data storage.

Features of Ceph Squid include improvements to BlueStore [a storage back end specifically designed for managing data on disk for Ceph Object Storage Daemon workloads] to reduce latency and CPU requirements for snapshot intensive workloads. BlueStore now uses RocksDB compression by default for increased average performance and reduced space usage. [And the next-generation Crimson OSD also has improvements in stability and read performance, and "now supports scrub, partial recovery and osdmap trimming."]

Ceph continues to drive the future of storage, and welcomes developers, partners, and technology enthusiasts to get involved.
Ceph Squid also brings enhancements for the CRUSH algorithm [which computes storage locations] to support more flexible and cost effective erasure coding configurations.

The U.S. Court of Appeals for the 2nd Circuit overturned a prior district court decision, lifting the injunction that blocked New York's law mandating that ISPs offer $15 broadband plans to low-income families. Ars Technica reports: The ruling (PDF) is a loss for six trade groups that represent ISPs, although it isn't clear right now whether the law will be enforced. For consumers who qualify for means-tested government benefits, the state law requires ISPs to offer "broadband at no more than $15 per month for service of 25Mbps, or $20 per month for high-speed service of 200Mbps," the ruling noted. The law allows for price increases every few years and makes exemptions available to ISPs with fewer than 20,000 customers.

"First, the ABA is not field-preempted by the Communications Act of 1934 (as amended by the Telecommunications Act of 1996), because the Act does not establish a framework of rate regulation that is sufficiently comprehensive to imply that Congress intended to exclude the states from entering the field," a panel of appeals court judges stated in a 2-1 opinion. Trade groups claimed the state law is preempted by former Federal Communications Commission Chairman Ajit Pai's repeal of net neutrality rules. Pai's repeal placed ISPs under the more forgiving Title I regulatory framework instead of the common-carrier framework in Title II of the Communications Act.

2nd Circuit judges did not find this argument convincing: "Second, the ABA is not conflict-preempted by the Federal Communications Commission's 2018 order classifying broadband as an information service. That order stripped the agency of its authority to regulate the rates charged for broadband Internet, and a federal agency cannot exclude states from regulating in an area where the agency itself lacks regulatory authority. Accordingly, we REVERSE the judgment of the district court and VACATE the permanent injunction."
