Memtest86+ just got its first update after 9 years. The program has reportedly been rewritten from scratch and is back in active development. The new version, 6.0, features a plethora of updates to bring the application up to date, and support the latest system hardware from Intel and AMD. Tom's Hardware reports: For the uninitiated, MemTest86 was originally created back in the mid 1990s, and was one of the earliest DDR memory testing applications for personal computers. But development stopped in 2013 once Memtest86 was split into Memtest86 and Memtest86", with the former being bought by PassMark. Officially, we don't know why development stopped. But compared to the now modern Memtest86, Memtest86+ is the open-source variant.

Needless to say, version 6.00 features a lot of updates, which were required to bring it up to modern standards compared to the 2013 version. The new version includes completely rewritten code for UEFI-based motherboards, the modern version of a BIOS, for both 32-bit and 64-bit versions of the application. Furthermore, the application features added support for x64 long mode paging, support for up to 256 cores, added detection for DDR4 and DDR5 memory -- since DDR3 was the latest memory standard in 2013 -- and adds support for XMP version 3.0.

CPU support has been significantly enhanced, addingdetection for all pre-Zen and AMD Zen-based processors ranging from the Ryzen 1000 series to 7000 series, and any older parts that were made after 2013. Intel support has also been added for chips up to 13th gen Raptor Lake. Finally, the last patch notes indicate version 6.0 adds support for older Nvidia and AMD chipsets - probably pre-2010 since it mentions Nvidia nForce chipsets, along with numerous bug fixes, optimizations and enhancements.

"Linus Torvalds has backed the idea of possibly removing Intel 486 (i486) processor support from the Linux kernel," reports Phoronix: After the Linux kernel dropped i386 support a decade ago, i486 has been the minimum x86 processor support for the mainline Linux kernel. This latest attempt to kill off i486 support ultimately arose from Linus Torvalds himself with expressing the idea of possibly requiring x86 32-bit CPUs with "cmpxchg8b" support, which would mean Pentium CPUs and later:

Maybe we should just bite the bullet, and say that we only support x86-32 with 'cmpxchg8b' (ie Pentium and later).

Get rid of all the "emulate 64-bit atomics with cli/sti, knowing that nobody has SMP on those CPU's anyway", and implement a generic x86-32 xchg() setup using that try_cmpxchg64 loop.

I think most (all?) distros already enable X86_PAE anyway, which makes that X86_CMPXCHG64 be part of the base requirement.

Not that I'm convinced most distros even do 32-bit development anyway these days.... We got rid of i386 support back in 2012. Maybe it's time to get rid of i486 support in 2022?
Towards the end of his post, Torvalds makes the following observation about i486 systems. "At some point, people have them as museum pieces. They might as well run museum kernels. "

Iran has one nuclear power plant. The email system of the company operating it was just breached, according to Iran's civil nuclear arm. The Associated Press reports: An anonymous hacking group claimed responsibility for the attack on Iran's Atomic Energy Organization, demanding Tehran release political prisoners arrested in the recent nationwide protests. The group said it leaked 50 gigabytes of internal emails, contracts and construction plans related to Iran's Russian-backed nuclear power plant in Bushehr and shared the files on its Telegram channel. It was unclear whether the breached system contained classified material.

The hack comes as Iran continues to face nationwide unrest...

"It might be a while before you can buy a 'Roomba for laundry'," jokes Slashdot reader Tony Isaac, pointing out that "while robots have been developed that can fold specific types of laundry, there's still not a good robot that can do the job quickly, or for all types."

But NPR reports laundry-folding robots are getting closer: As NPR has reported, machines need clear rules in order to function, and it's hard for them to figure out what exactly is going on in those messy piles That's not to say that it's completely impossible. University of California, Berkeley professor Pieter Abbeel spent years teaching a robot how to fold a towel, eventually cutting that process down from 20 minutes to a whopping minute and a half.

And Silicon Valley-based company FoldiMate raised hopes and eyebrows when it showed off a prototype of its eponymous laundry-folding robot at the Consumer Electronics Show in early 2019. It said the machine could fold some 25 pieces of laundry — except for small items like socks and large items like sheets — in under five minutes, with an estimated price tag of $980. It's unclear what happened to that company — its website is down and it hasn't tweeted since April 2020. Its sole competitor, a Japanese company with an AI-powered prototype, filed for bankruptcy.

In sum, most robots have not generally been equipped for the task. But an international group of researchers say their new method could change that — or at least speed up the process. Researchers are calling the new method, SpeedFolding. It's a "reliable and efficient bimanual system" — meaning it involves two hands — that's able to smooth and fold a crumpled garment in record speed (for robots, that is). SpeedFolding can fold 30 to 40 strewn-about garments per hour, compared to previous models that averaged three to six garments in that same time span, according to researchers. They say their robot can fold items in under two minutes, with a success rate of 93%.

"Real-world experiments show that the system is able to generalize to unseen garments of different color, shape, and stiffness," they add.
According to the article, the team will be presenting their paper at a robotics conference in Kyoto this month, and they've also posted a one-minute video on YouTube. (Their solution involves both an overhead camera and a novel neural network called BiManual Manipulation Network that "studied 4,300 human and machine-assisted actions in order to learn how to smooth and fold garments from a random configuration."

"While researchers describe SpeedFolding as a significant improvement, it's not likely to hit the market anytime soon," notes NPR. "For one, Ars Technica tracked down a robot similar to the one they used and found that it retails for $58,000."

IEEE Spectrum reports that "Standard electric-vehicle batteries can recharge much of their range in just 10 minutes with the addition of a thin sheet of nickel inside them, a new study finds." This could provide a welcome and economically attractive alternative to expensive EVs that carry massive and massively expensive battery packs. If faster-charging options were available, enabling the EV's sticker price to drop substantially, some researchers suspect consumers' EV phobia and industry dogma against "range anxiety" could be overcome....

In the new study, researchers experimented with a lithium-ion battery with a roughly 560-kilometer range when fully charged. (The battery's energy density was 265 watt-hours-per-kilogram.) By adding an ultrathin nickel foil to its interior [to heat the battery quickly], they could recharge it to 70 percent in 11 minutes for a roughly 400-km range, and 75 percent in 12 minutes for a roughly 440-km range.

"Our technology enables smaller, faster-charging batteries to be deployed for mass adoption of affordable electric cars," says study senior author Chao-Yang Wang, a battery engineer at Pennsylvania State University....

The scientists detailed their findings online in the journal Nature.

"Farmers have urged whoever succeeds Liz Truss as UK prime minister to abandon plans to ban solar energy from most of England's farmland," reports the Guardian, "arguing that it would hurt food security by cutting off a vital income stream." Truss, who resigned on Thursday, and her environment secretary, Ranil Jayawardena, hoped to ban solar from about 41% of the land area of England, or about 58% of agricultural land, the Guardian revealed last week. They planned to do this by reclassifying less productive farmland as "best and most valuable", making it more difficult to use for energy infrastructure.

Members of the Country Land and Business Association (CLA), which represents 33,000 landowners, told the Guardian having solar on their less productive land allowed them to subsidise food production during less successful years, as well as providing cheap power for their estates and homes in their local area.
One farmer made the case succinctly to the Guardian. "We make unequivocally more from our solar panels than from farming."

Hardcore overclocker Elmor "officially broke the CPU frequency world record with Intel's brand-new Core i9-13900K 24-core processor," reports Tom's Hardware — by hitting "a staggering 8.812GHz using liquid nitrogen cooling, dethroning the 8-year reigning champion, the FX-8370, by 90MHz." That's right; it took eight years for a new CPU architecture to dethrone AMD's FX series processors. Those chips are infamous for their mediocre CPU performance at launch; however, these chips scaled incredibly well under liquid nitrogen overclocking....

Elmor accomplished this monumental feat thanks to Intel's new highly-clocked 13th Gen Raptor Lake CPU architecture. Out of the box, the Core i9-13900K can run over 5.5GHz on all P-cores while also hitting 5.8GHz under lightly threaded workloads. The 13900K is, by far, Intel's highest-clocking chip to date.

Meet Crimson Storage, the world's largest single-phase battery, which is now live in the California desert. Electrek reports: Crimson Storage is also the second-largest energy storage project currently in operation of any configuration. The 350 megawatt (MW)/1400 megawatt-hour (MWh) battery storage project, which sits on on 2,000 acres west of Blythe in Riverside County, broke ground in 2021. Canadian Solar oversaw construction and provided the battery energy storage systems, and Axium Infrastructure and solar and storage developer Recurrent Energy will be Crimson Storage's long-term owners.

Residential homes are usually served by a single-phase power supply, and this project, on average, is expected to store and dispatch enough electricity to power more than 47,000 homes each year. Crimson Storage holds two long-term contracts with local utilities: a 200 MW/800 MWh 14-year and 10-month contract with Southern California Edison, and a 150 MW/ 600MWh 15-year contract with Pacific Gas and Electric.

BMW says it will make batteries for its electric vehicles at a factory in South Carolina in the latest move by a major automaker to localize EV production in the United States. The Verge reports: The German company plans to invest $1.7 billion in the US, including $1 billion for EV production at BMW's Spartanburg plant and $700 million for a new battery-assembly facility in nearby Woodruff. By 2030, BMW says it will have at least six electric models in production in the US. Establishing a US-based EV plant will allow BMW's upcoming line of plug-in vehicles to qualify for the federal EV tax credit.

BMW said it is partnering with Envision AESC on its plans for a dedicated battery plant in South Carolina. The Japan-based energy company will produce round lithium-ion battery cells specifically designed for BMW's next-gen EV platform. When it's completed, the battery factory will have an annual capacity of 30 gigawatt-hours (GWh). BMW has also announced plans to build EV production facilities in Europe and China to meet demand. The company currently has several electric models for sale, including the i4 sedan and iX SUV.

What secrets does the inside of the Pixel Watch hold? iFixit -- Google's new repair partner -- tore down Google's first self-branded smartwatch to see exactly how this thing was put together. From a report: Like us, iFixit came away with strong "first generation" vibes. The good news is that it does not look impossible to replace the display. The usual bit of heat and prying pops the top off, but the less-than-ideal layout means you'll have to remove the battery, too, since the connector is buried under the soft battery pouch. A display replacement is a real concern here, considering the entire top half of the watch is glass. If you bang the watch against something or drop it, there's a good chance you'll shatter the all-glass corners. [...] iFixit took a good amount of time in the four-minute video to call Google's internal construction "ugly." After cracking open the front, iFixit's Sam Goldheart noted, "Right away, it's obvious we're in Android country. The silver battery pouch and Kapton tape are almost a shock after all our Apple teardowns," later adding that the welds holding together the haptic feedback buzzer were "kind of ugly."

An anonymous reader quotes a report from Ars Technica: Today, tech archivist Jason Scott announced a new website called Discmaster that lets anyone search through 91.7 million vintage computer files pulled from CD-ROM releases and floppy disks. The files include images, text documents, music, games, shareware, videos, and much more. The files on Discmaster come from the Internet Archive, uploaded by thousands of people over the years. The new site pulls them together behind a search engine with the ability to perform detailed searches by file type, format, source, file size, file date, and many other options.

Discmaster is the work of a group of anonymous history-loving programmers who approached Scott to host it for them. Scott says that Discmaster is "99.999 percent" the work of that anonymous group, right down to the vintage gray theme that is compatible with web browsers for older machines. Scott says he slapped a name on it and volunteered to host it on his site. And while Scott is an employee of the Internet Archive, he says that Discmaster is "100 percent unaffiliated" with that organization.

One of the highlights of Discmaster is that it has already done a lot of file format conversion on the back end, making the vintage files more accessible. For example, you can search for vintage music files -- such as MIDI or even digitized Amiga sounds -- and listen to them directly in your browser without any extra tools necessary. The same thing goes for early-90s low-resolution video files, images in obscure formats, and various types of documents. "It's got all the conversion to enable you to preview things immediately," says Scott. "So there's no additional external installation. That, to me, is the fundamental power of what we're dealing with here." "The value proposition is the value proposition of any freely accessible research database," Scott told Ars Technica. "People are enabled to do deep dives into more history, reference their findings, and encourage others to look in the same place."

"[Discmaster] is probably, to me, one of the most important computer history research project opportunities that we've had in 10 years," says Scott. "It's not done. They've analyzed 7,000 and some-odd CD-ROMs. And they're about to do another 8,000."

The failure rate of semiconductors shipped from China to Russia has increased by 1,900 percent in recent months, according to Russian national business daily Kommersant. The Register reports: Quoting an anonymous source, Kommersant states that before Russia's illegal invasion of Ukraine the defect rate in imported silicon was two percent. Since that war commenced, Russian manufacturers have apparently faced 40 percent failure rates. Even a two percent defect rate is sub-optimal, because products made of many components can therefore experience considerable quality problems. Forty percent failure rates mean supplies are perilously close to being unfit for purpose.

According to Kommersant, Russian electronics manufacturers are not enjoying life at all because, on top of high failure rates, gray market gear doesn't flow with the same speed as legit kit and supply chains are currently very kinked indeed inside Russia. The newspaper lays the blame on economic sanctions that have seen many major businesses quit Russia. Gray market distributors and other opportunistic operators have been left as the only entities willing to deal with Russian businesses. Gray market folks are not renowned for their sterling customer service nor their commitment to quality. They get away with it because buyers of products with -- ahem -- unconventional origins self-incriminate if they complain to authorities. Perhaps they're even dumping dud product on Russian buyers, knowing that they can't easily access alternatives.

A new report from The Information details more changes Google CEO Sundar Pichai's budget cuts are having across the company, with some divisions surviving and others getting ominous resource cuts. From a report: First, we have news that the hardware division, other than losing laptops, seems mostly safe. Google's biggest Android partner, Samsung, is in decline in many established markets, and Apple is hitting an all-time high in US market share last quarter. The report says Google views Apple as more of a problem than it has in the past, thanks to worries that regulators might shut down the usual multi-billion-dollar Google/Apple agreement to put Google Search on iPhones. If iPhones stop showing Google ads, the rise of Apple and fall of Samsung is one of the few things that could actually be a major problem for Google's revenue.

According to the report, Google views itself as the solution to this problem. As a hedge against what the report calls the "further decline" of Samsung, Google is "doubling down" on its investment in Pixel hardware. Google is apparently doing this by "moving product development and software engineering staff working on features for non-Google hardware to work on Google-branded devices." The goal here is to not spend more money, so Google is apparently sacrificing partner devices to focus on the Pixel division. So what projects are seeing cuts? Google TV is one, with the report saying: "Executives also have discussed moving some product managers working on Google TV software for television sets" to Wear OS and the Pixel Tablet. This is the only OS called out as specifically receiving less OS development. A lot of this report seems to focus on cuts to Google Assistant's support for specific form factors, which is strange since Google Assistant is more or less the same on every platform. The whole point of the Assistant is one reliable, predictable voice assistant that lives everywhere, and it's not clear what platform-specific support needs to be done other than whipping up an app that can receive audio and read back results.

German Chancellor Olaf Scholz has asked the economy, environment and finance ministries to lay the legal framework to keep the country's three nuclear power plants operational until as late as April 15, 2023, a letter seen by Reuters showed on Monday. Reuters reports: Germany had planned to complete a phase-out of nuclear power by the end of this year, but a collapse in energy supplies from Russia because of the war in Ukraine has prompted the government to keep two plants on standby. Lengthy disagreements within the ruling coalition government over the merits and drawbacks of nuclear energy delayed the implementation of a draft law to put the two plants on reserve beyond their planned phase-out at the end of this year.

As well as the Isar II and Neckarwestheim II plants already included in the draft law, Finance Minister Christian Lindner has been pushing to keep a third plant, Emsland, operational, which Economy Minister Robert Habeck -- whose Green Party is historically anti-nuclear -- agreed to. The three plants have 4,300 megawatts (MW) of power capacity, contributing 6% to Germany's electricity production this year. Scholz also requested that the ministries present an "ambitious" law to increase energy efficiency, and put into law an agreement to phase out coal by 2030.

Following increased U.S. export controls against working with Chinese companies, Apple has halted plans to use YMTC chips in the iPhone. AppleInsider reports: According to Nikkei Asia, YMTC flash memory is at least 20% cheaper than that of rivals, and the company's 128-layer 3D NAND chips are the most advanced by a Chinese company. They remain reportedly one or two generations behind the chips made by Micron and Samsung, both of which are known to be working with Apple. Nikkei Asia claims that Apple had completed is months-long testing and verification. Political pressure and criticism from US policymakers made it abandon the plan.

"The products have been verified, but they did not go into the production lines when mass production of the new iPhone began," an unspecified source told Nikkei Asia. Reportedly, the intention had been to initially use YMTC chips only for iPhones being sold in China. Another unnamed source, though, claimed that Apple was considering ultimately buying 40% of all its worldwide iPhone NAND flash memory from the company. "YMTC is government-subsidized so they can really outprice competitors," said another source.

South Korea's two largest domestic internet companies, Naver and Kakao, have experienced significant service interruptions after the datacenter that hosts much of their infrastructure was shut down by a Sunday fire. The Register reports: The datacenter in question is operated by SK C&C, one of the many arms of South Korean conglomerate SK. SK C&C offers a range of cloud and tech infrastructure services, bills itself as a "total digital transformation partner" and operates three datacenters, in which it happily houses client systems. The one in Pangyo, just south of South Korea's capital Seoul, was built in 2014, covers 66,942 square meters, and boasts what SK C&C describes as "Latest/eco-friendly technology". And it caught fire on the weekend. The company has not said what cause the facility to catch fire, nor the extent of the blaze.

But many services from Kakao and Naver were unavailable for many hours at a time, starting from Saturday afternoon. Impact of the outages was wide. The tweet below is an example of one business's reaction. Kakao has acknowledged the outage in a blog post that apologizes for the service interruption and slow restoration, and admits that disaster recovery efforts were delayed. The company has created an Emergency Response Committee and three sub-committees -- one to probe the cause of the incident, another to develop disaster countermeasures, and a third to arrange compensation for stakeholders. Naver's announcement admits that "some functions such as search, news, shopping, cafe, blog, open talk, and smart store center had errors." The company says all services have now been restored.

Chip delivery times shrank by four days in September, the biggest drop in years, in a sign that the industry's supply crunch is easing. From a report: Lead times -- the gap between when a chip is ordered and when it is delivered -- averaged 26.3 weeks in the period, according to research by Susquehanna Financial Group. That compares with nearly 27 weeks the prior month. Wait times contracted for all key product categories, with power-management and analog chips seeing the biggest declines, Susquehanna analyst Christopher Rolland said in a research note. A global chip shortage bedeviled a wide range of industries in the past year, with automakers and other manufacturers struggling to get enough semiconductors. Pockets of supply constraints remain, but now many chipmakers are concerned about the opposite problem: chip inventory getting too high.

The courier company FedEx is abandoning a project to develop last-mile delivery robots. In 2019, FedEx partnered with New Hampshire-based DEKA Research and Development Corp, founded by Segway inventor Dean Kamen, to develop a wheeled robot called Roxo for last-mile deliveries. From a report: But FedEx decided to end the project in early October, according to a report in Robotics 24/7. FedEx employees were told of the decision via an email from the company's chief transformation officer, Sriram Krishnasamy, who explained a new corporate strategy called "DRIVE." "Although robotics and automation are key pillars of our innovation strategy, Roxo did not meet necessary near-term value requirements for DRIVE. Although we are ending the research and development efforts, Roxo served a valuable purpose: to rapidly advance our understanding and use of robotic technology," Krishnasamy wrote. Roxo is a 62-inch-tall (1,575-mm) package bot; it weighs 450 lbs (204 kg) and has a cargo capacity of up to 100 lbs (45 kg). It was designed to navigate around sidewalks and roadsides and between pedestrians and parked cars to deliver its cargo to a customer's door. It combines a 360-degree lidar sensor with 360-degree long-range cameras above its rounded shell. There are 180-degree stereo cameras and a 360-degree radar sensor around the base, and a display that can deliver messages is set into the front of the bot.

"You know you're a nerd when you store DNA in your fridge," says Dina Zielinski, a senior scientist in human genomics at the French National Institute of Health and Medical Research tells the BBC — holding up a tiny vial with a light film at the bottom: But this DNA is special. It does not store the code from a human genome, nor does it come from any animal or virus. Instead, it stores a digital representation of a museum. "That will last easily tens of years, maybe hundreds," says Zielinski.

Research into how we could store digital data inside strands of DNA has exploded over the past decade, in the wake of efforts to sequence the human genome, synthesise DNA and develop gene therapies. Scientists have already encoded films, books and computer operating systems into DNA. Netflix has even used it to store an episode of its 2020 thriller series Biohackers.

The information stored in DNA defines what it is to be human (or any other species for that matter). But many experts argue it offers an incredibly compact, durable and long-lasting form of storage that could replace the many forms of unreliable digital media available, which regularly become defunct and require huge amounts of energy to store. Meanwhile, some researchers are exploring other ways we could store data effectively forever, such as etching information onto incredibly durable glass beads, a modern take on cave drawings.
Even before the issue of the energy required to power (and cool) data centers, Zielinski points out that data stored on hard drives "lasts on average maybe 10 to 20 years, maybe 50 if you're lucky and the conditions are perfect." And yet we've already been able to recover DNA from million-year-old wooly mammoths...

Olgica Milenkovic, a professor of electrical and computer engineering at the University of Illinois at Urbana-Champaign, acknowledges that DNA can be damaged by things like humidity, acids, and radiation — "But if it's kept cold and dry, it's good for hundreds of years." And if it's stored in an ice vault, "it can last forever, pretty much." (And unlike floppy disks — DNA-formatted data will never become obsolete.)

It's not the only option. Peter Kazansky, a professor in optoelectronics at the University of Southampton, has created an optical storage technology that etches nano-structures onto glass disks. But Latchesar Ionkov, a computer scientist working on DNA storage at Los Alamos National Laboratory, believes we're just decades away from being able to store the estimated 33 zettabytes of data that humans will have produced by 2025 in a space the size of a ping-pong ball.

When a kernel developer asked Linus Torvalds if he'd missed a Git pull, Torvalds "revealed the request was still in his queue as 'I'm doing merges (very slowly) on my laptop, while waiting for new ECC memory DIMMs to arrive,'" reports The Register: Torvalds needs the DIMMs because over the last few days he experienced what he described as "some instability on my main desktop... with random memory corruption in user space resulting in my allmodconfig builds randomly failing with internal compiler errors etc."

The Linux boss's first thought was that a new kernel bug had caused the problem — which isn't good but sometimes happens. His instinct was wrong. "It was literally a DIMM going bad in my machine randomly after 2.5 years of it being perfectly stable," he wrote. "Go figure. Verified first by booting an old kernel, and then with memtest86+ overnight."

Torvalds appears to have been tracking delivery of the new DIMMs as he reported replacement memory was "out for delivery" and predicted it should arrive later on Sunday evening....

His post also mentions that his main PC was set up for error correction code memory (ECC memory), but "during the early days of COVID when there wasn't any ECC memory available at any sane prices. And then I never got around to fixing it, until I had to detect errors the hard way."

"I absolutely *detest* the crazy industry politics and bad vendors that have made ECC memory so 'special'," he added.
