Longtime Slashdot reader Baron_Yam writes: Memristors are the long-sought 4th fundamental circuit element. They promise analog computing capability in hardware, the ability to hold state without power, and to work with less power. A small cluster of them can replace a transistor using less space. Working and long term storage can blend together and neural networks can be implemented in hardware -- they are a game-changing innovation. Now, researchers are getting closer to putting these into production as they can now produce graphene-based memristors at wafer scale. "One of the key challenges in memristor development is device degradation, which graphene can help prevent," reports Phys.Org. "By blocking chemical pathways that degrade traditional electrodes, graphene could significantly extend the lifetime and reliability of these devices. Its remarkable transparency, transmitting 98% of light, also opens doors to advanced computing applications, particularly in AI and optoelectronics."

The findings have been published in the journal ACS Advanced Electronic Materials.

whitroth writes: People here and elsewhere have been yelling for more nuclear power, and that renewables can't meet demand. Surprise -- the corporations are betting on them, and massive numbers of batteries can be produced a lot faster than nuclear plants can be built. The Guardian adds: Faced with worsening climate-driven disasters and an electricity grid increasingly supplied by intermittent renewables, the US is rapidly installing huge batteries that are already starting to help prevent power blackouts. From barely anything just a few years ago, the US is now adding utility-scale batteries at a dizzying pace, having installed more than 20 gigawatts of battery capacity to the electric grid, with 5GW of this occurring just in the first seven months of this year, according to the federal Energy Information Administration (EIA). This means that battery storage equivalent to the output of 20 nuclear reactors has been bolted on to America's electric grids in barely four years, with the EIA predicting this capacity could double again to 40GW by 2025 if further planned expansions occur.

California and Texas, which both saw all-time highs in battery-discharged grid power this month, are leading the way in this growth, with hulking batteries helping manage the large amount of clean yet intermittent solar and wind energy these states have added in recent years.

An anonymous reader quotes a report from SecurityWeek.com: White hat hackers taking part in the Pwn2Own Ireland 2024 contest organized by Trend Micro's Zero Day Initiative (ZDI) have earned half a million dollars on the first day of the event, for exploits targeting NAS devices, cameras, printers and smart speakers. The highest single reward, $100,000, was earned by Sina Kheirkhah of Summoning Team, who chained a total of nine vulnerabilities for an attack that went from a QNAP QHora-322 router to a TrueNAS Mini X storage device. Another exploit chain involving the QNAP QHora-322 and TrueNAS Mini X products was demonstrated by Viettel Cyber Security, but this team earned only $50,000.

A significant reward was also earned by Jack Dates of RET2 Systems, who received $60,000 for hacking a Sonos Era 300 smart speaker. QNAP TS-464 and Synology DiskStation DS1823XS+ NAS device exploits earned $40,000 each for two different teams. Participants also successfully demonstrated exploits against the Lorex 2K WiFi, Ubiquity AI Bullet, and Synology TC500 cameras, and HP Color LaserJet Pro MFP 3301fdw and Canon imageCLASS MF656Cdw printers. These attempts earned the hackers between $11,000 and $30,000. According to ZDI, a total of $516,250 was paid out on the first day of Pwn2Own Ireland for over 50 unique vulnerabilities.

San Francisco's Municipal Transportation Agency approved a $212 million contract with Hitachi Rail to modernize the Muni Metro system's outdated train control system, which currently uses floppy disks and wire loops. Government Technology reports: The software that runs the system is stored on floppy disks that are loaded each morning and an outdated type of communication using wire loops that are easily disrupted. It was expected to last for 20 to 25 years, according to Muni officials. It moves data more slowly than a wireless modem, they said. By late 2027 and into 2028, a new communications-based system, which employs Wi-Fi and cell signals to precisely track the locations of trains, will be installed by Hitachi, which will provide support services for 20 years under the agreement.

While the current train control system operates only on the Market Street subway and Central Subway, the new system will control Metro light rail trains on the system's surface lines as well. The Hitachi system is said to be five generations ahead of the current system, said Muni Director of Transit Julie Kirschbaum, who described it as the best train control system on the market.

An anonymous reader quotes a report from Ars Technica: 37Signals is not a company that makes its policy or management decisions quietly. The productivity software company was an avowedly Mac-centric shop until Apple's move to kill home screen web apps (or Progressive Web Apps, or PWAs) led the firm and its very-public-facing co-founder, David Heinemeier Hansson, to declare a "Return to Windows," followed by a stew of Windows/Mac/Linux. The company waged a public battle with Apple over its App Store subscription policies, and the resulting outcry helped nudge Apple a bit. 37Signals has maintained an active blog for years, its co-founders and employees have written numerous business advice books, and its blog and social media posts regularly hit the front pages of Hacker News.

So when 37Signals decided to pull its seven cloud-based apps off Amazon Web Services in the fall of 2022, it didn't do so quietly or without details. Back then, Hansson described his firm as paying "an at times almost absurd premium" for defense against "wild swings or towering peaks in usage." In early 2023, Hansson wrote that 37Signals expected to save $7 million over five years by buying more than $600,000 worth of Dell server gear and hosting its own apps.

Late last week, Hansson had an update: it's more like $10 million (and, he told the BBC, more like $800,000 in gear). By squeezing more hardware into existing racks and power allowances, estimating seven years' life for that hardware, and eventually transferring its 10 petabytes of S3 storage into a dual-DC Pure Storage flash array, 37Signals expects to save money, run faster, and have more storage available. "The motto of the 2010s and early 2020s -- all-cloud, everything, all the time -- seems to finally have peaked," Hansson writes. "And thank heavens for that!" He adds the caveat that companies with "enormous fluctuations in load," and those in early or uncertain stages, still have a place in the cloud.

MIT engineers have built a solar-powered desalination system that "ramps up its desalting process and automatically adjusts to any sudden variation in sunlight, for example by dialing down in response to a passing cloud or revving up as the skies clear."

While traditional reverse osmosis systems typically require steady power levels, "the MIT system requires no extra batteries for energy storage, nor a supplemental power supply, such as from the grid." And their results were pretty impressive: The engineers tested a community-scale prototype on groundwater wells in New Mexico over six months, working in variable weather conditions and water types. The system harnessed on average over 94 percent of the electrical energy generated from the system's solar panels to produce up to 5,000 liters of water per day despite large swings in weather and available sunlight... "Being able to make drinking water with renewables, without requiring battery storage, is a massive grand challenge," says Amos Winter, the Germeshausen Professor of Mechanical Engineering and director of the K. Lisa Yang Global Engineering and Research Center at MIT. "And we've done it."

The system is geared toward desalinating brackish groundwater — a salty source of water that is found in underground reservoirs and is more prevalent than fresh groundwater resources. The researchers see brackish groundwater as a huge untapped source of potential drinking water, particularly as reserves of fresh water are stressed in parts of the world. They envision that the new renewable, battery-free system could provide much-needed drinking water at low costs, especially for inland communities where access to seawater and grid power are limited...

The researchers' report details the new system in a paper appearing in Nature Water. The study's co-authors are Bessette, Winter, and staff engineer Shane Pratt... "Our focus now is on testing, maximizing reliability, and building out a product line that can provide desalinated water using renewables to multiple markets around the world," Pratt adds. The team will be launching a company based on their technology in the coming months.

This research was supported in part by the National Science Foundation, the Julia Burke Foundation, and the MIT Morningside Academy of Design. This work was additionally supported in-kind by Veolia Water Technologies and Solutions and Xylem Goulds.

An anonymous reader quotes a report from TorrentFreak: Korean game publisher Nexon is using the U.S. legal system to address online copyright infringement. The company obtained a DMCA subpoena that requires Discord to hand over the personal details of suspected pirates. While Discord has shared information in the past, it doesn't plan to cooperate any longer, refusing to play the role of 'anti-piracy police'. [...] The messaging platform wrote that it is prepared to file a motion to quash the subpoena, if needed. It further urged Nexon to withdraw their demands, and cease sending any similar 'defective' subpoenas going forward. To support its stance, Discord made a list of twenty-two general objections and reservations. Among other things, the company wants to protect user privacy and their first amendment right to anonymous speech.

"Discord objects to the Requests as infringing its users' decisions to remain anonymous, an aspect of their freedom of speech protected by the First Amendment. The Requests improperly seek to unmask anonymous speakers and consequently compel disclosure of material protected by the First Amendment," it reads. This strongly-worded letter didn't have the desired result, however. Instead of backing off, Nexon doubled down, filing a motion to compel (PDF) at a Texas federal court late last week. The game company refutes Discord's objections and asks the court to enter an order requiring Discord to produce the requested user data. Nexon says that it needs this information to protect its copyrights. "Discord's failure to cooperate discovery has impeded Nexon's ability to discover relevant, non-privileged information that will support its potential claims against the users who have provided access to the infringing material," Nexon writes. While the court has yet to rule on the matter, Discord is expected to file a formal motion to quash the subpoena in response, as indicated in its earlier communications.

Longtime Slashdot reader mprindle shares a report from BleepingComputer: Cisco has confirmed to BleepingComputer that it is investigating recent claims that it suffered a breach after a threat actor began selling allegedly stolen data on a hacking forum. [...] This statement comes after a well-known threat actor named "IntelBroker" said that he and two others called "EnergyWeaponUser and "zjj" breached Cisco on October 6, 2024, and stole a large amount of developer data from the company.

"Compromised data: Github projects, Gitlab Projects, SonarQube projects, Source code, hard coded credentials, Certificates, Customer SRCs, Cisco Confidential Documents, Jira tickets, API tokens, AWS Private buckets, Cisco Technology SRCs, Docker Builds, Azure Storage buckets, Private & Public keys, SSL Certificates, Cisco Premium Products & More!," reads the post to a hacking forum. IntelBroker also shared samples of the alleged stolen data, including a database, customer information, various customer documentation, and screenshots of customer management portals. However, the threat actor did not provide further details about how the data was obtained.

In a press release this morning, Apple announced a new iPad Mini with a faster A17 Pro chip that supports Apple Intelligence. The Verge reports: The new Mini is mostly a spec bump: it runs a new A17 Pro chip, which Apple says has a 30 percent faster CPU, 25 percent faster GPU, and a Neural Engine twice as fast as the previous model. The device also supports the new Apple Pencil Pro, which is a nice touch for the Mini-toting artists out there, and comes with 128GB of storage in the base model rather than 64GB. (Those AI models need all the space they can get.) The Wi-Fi 6E chip is faster, the USB-C port is faster, everything about the iPad Mini is the same as before only faster this time.

The only real design change with the new Mini is the colors. Apple's gone more colorful with a lot of its products this year, and the Mini comes in new purple and blue models. In photos they look muted rather than vivid, though, so don't expect the eye-popping new colors on the iPhone 16.

SSD prices are set to drop up to 10% in Q4 2024, market research firm TrendForce has reported. The decline stems from increased production and weakening demand, particularly in the consumer sector. Enterprise SSD prices, however, may see a slight increase. TrendForce analysts attribute the softer demand partly to slower-than-expected adoption of AI PCs. The mobile storage market could experience even steeper price cuts, with eMMC and UFS components potentially falling 13% as smartphone makers deplete inventories. The forecast follows modest price reductions observed in Q3 2024.

In response to California's new law targeting "false advertising" of "digital goods," Valve has added the following language to its checkout page: "A purchase of a digital product grants a license for the product on Steam." Ars Technica reports: California's AB2426 law, signed by Gov. Gavin Newsom Sept. 26, excludes subscription-only services, free games, and digital goods that offer "permanent offline download to an external storage source to be used without a connection to the internet." Otherwise, sellers of digital goods cannot use the terms "buy, purchase," or related terms that would "confer an unrestricted ownership interest in the digital good." And they must explain, conspicuously, in plain language, that "the digital good is a license" and link to terms and conditions.

Which is what Valve has now added to its cart page before enforcement of these terms was due to start next year. The company has long made it clear, deeper inside its End User License Agreement (EULA), that a purchase is a license, and those licenses cannot be resold, which avoids issues of one's right to resell a game. Now it is something that every user sees on every purchase, however quickly they click-through to get to their download.

In a new 32-page filing (PDF), the Department of Justice indicated that it was considering a possible breakup of Google as an antitrust remedy for its search and advertising monopoly. The remedies necessary to "prevent and restrain monopoly maintenance could include contract requirements and prohibitions; non-discrimination product requirements; data and interoperability requirements; and structural requirements," the department said in the filing. CNBC reports: The DOJ also said it was "considering behavioral and structural remedies that would prevent Google from using products such as Chrome, Play, and Android to advantage Google search and Google search-related products and features -- including emerging search access points and features, such as artificial intelligence -- over rivals or new entrants."

Additionally, the DOJ suggested limiting or prohibiting default agreements and "other revenue-sharing arrangements related to search and search-related products." That would include Google's search position agreements with Apple's iPhone and Samsung devices -- deals that cost the company billions of dollars a year in payouts. The agency suggested one way to do this is requiring a "choice screen," which could allow users to pick from other search engines. Such remedies would end "Google's control of distribution today" and ensure "Google cannot control the distribution of tomorrow."

"Alleged photos and videos of an unannounced 14-inch MacBook Pro with an M4 chip continue to surface on social media, in what could be the worst product leak for Apple since an employee accidentally left an iPhone 4 prototype at a bar in California in 2010," writes MacRumors' Joe Rossignol. From the report: The latest video of what could be a next-generation MacBook Pro was shared on YouTube Shorts today by Russian channel Romancev768, just one day after another Russian channel shared a similar video. The clip shows a box for a 14-inch MacBook Pro that is apparently configured with an M4 chip with a 10-core CPU and a 10-core GPU, 16GB of RAM, 512GB of storage, three Thunderbolt 4 ports, and a Space Black finish. According to the "About This Mac" software menu shown in the video, the MacBook Pro in the video is allegedly an unreleased November 2024 model. [...]

Apple is well known for having a culture of secrecy, so this magnitude of leak is rarely seen for its products. As previously mentioned, this could be the most significant leak for Apple since Gizmodo obtained and shared photos of an iPhone 4 prototype that a then-employee of the company accidentally left behind at a bar in California. In that case, Apple got law enforcement involved, but how it acts this time around remains to be seen.

Veteran Microsoft engineer Larry Osterman is the latest to throw his hat into the "tabs versus spaces" ring. From a report: The debate has vexed engineers for decades -- is it best to indent code with tabs or spaces? Osterman, a four-decade veteran of Microsoft, was Team Tabs when storage was tight, but has since become Team Spaces with the advent of terabytes of relatively inexpensive storage. "Here's the thing," he said. "When you've got 512 kilobytes, and you're writing a program in Pascal with lots of indentation, if you're taking eight bytes for every one of those indentations, for eight spaces, you could save seven bytes in your program by using a tab character."

It all added up, even when floppy disks were part of the equation.

However, according to Osterman, things have changed. Storage is less of an issue, so why not use spaces? A cynic might wonder if that sort of attitude has led to the bloatware of today, where software requires ever-increasing amounts of storage in return for precious little extra functionality and a never-ending stream of patches. Any decent compiler should strip out any extraneous characters, assuming the code is indeed being compiled beforehand and not interpreted at run-time. For his part, Osterman is now a member of team spaces. "I like spaces simply because it always works and it's always consistent," he said.

"A cyberattack tied to the Chinese government penetrated the networks of a swath of U.S. broadband providers," reports the Wall Street Journal, "potentially accessing information from systems the federal government uses for court-authorized network wiretapping requests.

"For months or longer, the hackers might have held access to network infrastructure used to cooperate with lawful U.S. requests for communications data, according to people familiar with the matter, which amounts to a major national security risk." The attackers also had access to other tranches of more generic internet traffic, they said. Verizon Communications, AT&T and Lumen Technologies are among the companies whose networks were breached by the recently discovered intrusion, the people said.

The widespread compromise is considered a potentially catastrophic security breach and was carried out by a sophisticated Chinese hacking group dubbed Salt Typhoon. It appeared to be geared toward intelligence collection, the people said... The surveillance systems believed to be at issue are used to cooperate with requests for domestic information related to criminal and national security investigations. Under federal law, telecommunications and broadband companies must allow authorities to intercept electronic information pursuant to a court order. It couldn't be determined if systems that support foreign intelligence surveillance were also vulnerable in the breach...

The hackers appear to have engaged in a vast collection of internet traffic from internet service providers that count businesses large and small, and millions of Americans, as their customers. Additionally, there are indications that the hacking campaign targeted a small number of service providers outside the U.S., the people said. A person familiar with the attack said the U.S. government considered the intrusions to be historically significant and worrisome... "It will take time to unravel how bad this is, but in the meantime it's the most significant in a long string of wake-up calls that show how the PRC has stepped up their cyber game," said Brandon Wales, former executive director at the Cybersecurity and Infrastructure Security Agency and now a vice president at SentinelOne, referring to the People's Republic of China. "If companies and governments weren't taking this seriously before, they absolutely need to now."
Three weeks ago TechCrunch also reported that the FBI "took control of a botnet made up of hundreds of thousands of internet-connected devices, such as cameras, video recorders, storage devices, and routers, which was run by a Chinese government hacking group, FBI director Christopher Wray and U.S. government agencies revealed Wednesday.

An anonymous reader quotes a report from TechCrunch: The European Union's top court has sided with a privacy challenge to Meta's data retention policies. It ruled on Friday that social networks, such as Facebook, cannot keep using people's information for ad targeting indefinitely. The judgement could have major implications on the way Meta and other ad-funded social networks operate in the region. Limits on how long personal data can be kept must be applied in order to comply with data minimization principles contained in the bloc's General Data Protection Regulation (GDPR). Breaches of the regime can lead to fines of up to 4% of global annual turnover -- which, in Meta's case, could put it on the hook for billions more in penalties (NB: it is already at the top of the leaderboard of Big Tech GDPR breachers). [...]

The original challenge to Meta's ad business dates back to 2014 but was not fully heard in Austria until 2020, per noyb. The Austrian supreme court then referred several legal questions to the CJEU in 2021. Some were answered via a separate challenge to Meta/Facebook, in a July 2023 CJEU ruling -- which struck down the company's ability to claim a "legitimate interest" to process people's data for ads. The remaining two questions have now been dealt with by the CJEU. And it's more bad news for Meta's surveillance-based ad business. Limits do apply. Summarizing this component of the judgement in a press release, the CJEU wrote: "An online social network such as Facebook cannot use all of the personal data obtained for the purposes of targeted advertising, without restriction as to time and without distinction as to type of data."

The ruling looks important on account of how ads businesses, such as Meta's, function. Crudely put, the more of your data they can grab, the better -- as far as they are concerned. Back in 2022, an internal memo penned by Meta engineers which was obtained by Vice's Motherboard likened its data collection practices to tipping bottles of ink into a vast lake and suggested the company's aggregation of personal data lacked controls and did not lend itself to being able to silo different types of data or apply data retention limits. Although Meta claimed at the time that the document "does not describe our extensive processes and controls to comply with privacy regulations." How exactly the adtech giant will need to amend its data retention practices following the CJEU ruling remains to be seen. But the law is clear that it must have limits. "[Advertising] companies must develop data management protocols to gradually delete unneeded data or stop using them," noyb suggests. The court also weighed in a second question that concerns sensitive data that has been "manifestly made public" by the data subject, "and whether sensitive characteristics could be used for ad targeting because of that," reports TechCrunch. "The court ruled that it could not, maintaining the GDPR's purpose limitation principle."

On Wednesday, the SEC filed (PDF) to appeal a 2023 court ruling that determined XRP is not considered a security when sold to retail investors on exchanges. The announcement sent the price of XRP tumbling more than 8%. "XRP, which was created by the founders of Ripple, is the native token of the open source XRP Ledger, which Ripple uses in its cross-border payments business," notes CNBC. "It is the fifth-largest coin by market cap, excluding stablecoins Tether (USDT) and USD Coin (USDC)." CNBC reports: Ripple, the largest holder of XRP coins, scored a partial victory last summer after a three-year battle with the SEC. U.S. District Judge Analisa Torres handed down the decision, which was hailed as a landmark win for the crypto industry. Still, while XRP isn't considered a security when sold to retail investors on exchanges, it is considered an unregistered security offering if sold to institutional investors.

Ripple declined to comment but referred to Wednesday evening posts on X by CEO Brad Garlinghouse and chief legal officer Stuart Alderoty. Alderoty said the company is evaluating whether to file a cross appeal, and called the SEC's decision to appeal "disappointing, but not surprising." The SEC, under Chair Gary Gensler, has become notorious for its refusal to provide clear guidance for crypto businesses, instead opting to regulate by enforcement actions. "XRP's status as a non-security is the law of the land today - and that does not change even in the face of this misguided - and infuriating - appeal," Garlinghouse said on X.

An anonymous reader shares a report: The arrival of energy-assisted magnetic recording (EAMR) technologies like Seagate's HAMR will play a crucial role in accelerating HDD capacity growth in the coming years. According to the new IEEE International Roadmap for Devices and Systems Mass Data Storage, we will see 60 TB hard disk drives in 2028. If the prediction is accurate, we will see HDD storage capacity doubling in just four years, something that did not happen for a while. Also, IEEE believes that HDD unit sales will increase.

IEEE's latest HDD development roadmap spans 2022 to 2037 and covers 15 years of hard drive evolution. The arrival of HAMR in 2024 will play a pivotal role in the increase in HDD capacity (even though Western Digital has managed to stay competitive with Seagate's HAMR HDDs using a set of its technologies) over the next few years. IEEE engineers expect HDDs to leapfrog to 40TB in 2025 and 60TB in 2028, doubling capacity from 30TB in 2024. By 2037, there will be 100TB of storage space, according to IEEE.

To get to those extreme capacities, HDD makers will have to increase the areal density of their platters steadily. To get to 40TB per drive, they will have to get to 2 TB/inch^2 in 2025 and then to over 4 TB/inch^2 in 2028 to build 60TB HDDs. By 2037, areal density will grow to over 10 Tb/inch^2. Increasing areal density will necessitate the use of new media, magnetic films, and all-new write and read heads.

Mozilla has released Firefox 131 for multiple platforms, addressing security vulnerabilities and introducing some new features. The update fixes at least seven high-risk security issues, none reportedly exploited in the wild. New features include Tab Preview, which displays thumbnails and details when hovering over background tabs, and temporary location permission storage. Firefox now also supports URL fragment text directives, allowing users to link to specific text passages on web pages.

California Governor Gavin Newsom signed a law giving the California Energy Commission the authority to require bidirectional charging in electric vehicles (EVs) in the future -- although no timeline is set. Bidirectional charging allows EVs to not only charge from the grid but also supply electricity back to the grid, potentially enhancing grid resiliency, supporting renewable energy, and reducing peak electricity demand. Electrek reports: The idea started in 2023 when state Senator Nancy Skinner introduced a bill which would require EVs to have bidirectional charging by 2027. As this bill made its way through the legislative process, it got watered down from that ambitious timeline. So the current form of the bill, which is now called SB 59, took away that timeline and instead gave the California Energy Commission (CEC) the go-ahead to issue a requirement whenever they see it fit. The bill directs the CEC, the California Air Resources Board, and the California Public Utilities Commission to examine the use cases of bidirectional charging and give them the power to require specific weight classes of EVs to be bidirectional-capable if a compelling use case exists.

The state already estimates that integrating EVs into the grid could save $1 billion in costs annually, so there's definitely a use case there, but the question is the cost and immediacy of building those vehicles into the grid. The reason this can't be done immediately is that cars take time to design, and while adding bidirectional charging to an EV isn't the most difficult process, it also only really becomes useful with a whole ecosystem of services around the vehicle.

And that ecosystem has been a bit of a hard sell so far. It's all well and good to tell someone they can make $500/year by selling energy to the grid, but then you have to convince them to buy a more expensive charging unit and keep their car plugged in all the time, with someone else managing its energy storage. Some consumers might push back against that, so part of CEC's job is to wait to pull the trigger until it becomes apparent that people are actually interested in the end-user use case for V2G -- otherwise, no sense in requiring a feature that nobody is going to use.
