dcblogs writes: Japan's Fugaku ARM-based supercomputer is the world's most powerful in the latest Top500 list, setting a world record of 442 petaflops. But this was otherwise an unremarkable year for supercomputers, with a "flattening performance curve," said Jack Dongarra, one of the academics behind the twice-a-year ranking and director of the Innovative Computing Laboratory at the University of Tennessee. This is a result of Moore's Law slowing down as well as a slowdown in the replacement of older systems, he said. But the U.S. is set to deliver an exascale system -- 1,000 petaflops -- next year and China as well. Meanwhile, the EU has a 550 petaflop system in development in Finland. "On the Top500 list, the second-ranked system was IBM Power Systems at nearly 149 petaflops using its Power9 CPUs and Nvidia Tesla GPUs. It is at the Oak Ridge National Lab in Tennessee," adds TechTarget.

"Third place went to Sierra supercomputer, which also uses Power9 and Nvidia GPUs, at about 95 petaflops. It is at Lawrence Livermore National Laboratory in Livermore, Calif."

Long-time Slashdot reader shanen noticed a strange sound in one of their old machines, prompting them to ponder: what is the ultimate backup system? I've researched this topic a number of times in the past and never found a good answer...

I think the ultimate backup would be cloud-based, though I can imagine a local solution running on a smart storage device — not too expensive, and with my control over where the data is actually stored... Low overhead on the clients with the file systems that are being backed up. I'd prefer most of the work to be done on the server side, actually. That work would include identifying dupes while maintaining archival images of the original file systems, especially for my searches that might be based on the original folder hierarchies or on related files that I can recall being created around the same time or on the same machine...

How about a mail-in service to read old CDs and floppies and extract any recoverable data? I'm pretty sure I spotted an old box of floppies a few months ago. Not so much interested in the commercial stuff (though I do feel like I still own what I paid for) as I'm interested in old personal files — but that might call for access to the ancient programs that created those files.

Or maybe you want to share a bit about how you handle your backups? Or your version of the ultimate backup system...?
Slashdot reader BAReFO0t recommends "three disks running ZFS mirroring with scraping and regular snapshots, and two other locations running the same setup, but with a completely independent implementation. Different system, different PSU, different CPU manufacturer, different disks, different OS, different file system, different backup software, different building construction style, different form of government, etc."

shanen then added "with minimal time and effort" to the original question — but leave your own thoughts and suggestions in the comments.

What's your ultimate backup solution?

Tim McNerney is the project leader at 4004.com, a site commemorating Intel's original 4004 microprocessor. He's also long-time Slashdot reader mcpublic, and shares news of a new open source adapter — plus a great moment chip history: Even though Intel debuted its groundbreaking 4004 on November 15th, 1971, 49 years ago today, in the pages of Electronics News, there is something about Intel's very first microprocessor that keeps inspiring engineers to pay tribute to this historic chip.

Turkish iPhone engineer, Erturk Kocalar, (now at Google) and the force behind 8bitforce.com, just added this 4-bit granddaddy to his open-source lineup of 8-bit "Retroshields." These elegant little adapters let you score your favorite, vintage microprocessor on eBay and actually play around with it without having to wire up a multi-chip memory and the peripherals needed to make your little "engine" jolly fun. An Arduino emulates the rest of the system for you in software and lets you program and poke at your relic via USB from the comfort of a modern laptop.

Before FPGAs and yes, even before electronic CAD, there was a tradition of emulating hardware using software. In fact, it is central to the 4004 Genesis story. Busicom, a Japanese maker of mechanical adding machines, had designed its own electronic calculator chip-set and eagerly approached the now-famous Silicon Valley chip-maker to manufacture it. Back in 1969 Intel was just a tiny startup hoping to obsolete core memory with commodity semiconductors, and they didn't have extra logic designers on-staff. But Intel did have a prescient counter-proposal: we'll build you a general purpose computer-on-a-chip and emulate your custom calculator architecture using a ROM-conserving byte-code interpreter. Busicom agreed, and Intel managed to hire Italian superstar Federico Faggin away from Fairchild to craft a novel, customer-programmable microprocessor, which later, in 1975, German mechanical taxi meter maker Argo Kienzle would go on to launch the world's first electronic taxi meter. Starting to see a pattern of progress in everyday automation?

An anonymous reader quotes a report from IEEE Spectrum: While setting fire to an iron ingot is probably more trouble than it's worth, fine iron powder mixed with air is highly combustible. When you burn this mixture, you're oxidizing the iron. Whereas a carbon fuel oxidizes into CO2, an iron fuel oxidizes into Fe2O3, which is just rust. The nice thing about rust is that it's a solid which can be captured post-combustion. And that's the only byproduct of the entire business -- in goes the iron powder, and out comes energy in the form of heat and rust powder. Iron has an energy density of about 11.3 kWh/L, which is better than gasoline. Although its specific energy is a relatively poor 1.4 kWh/kg, meaning that for a given amount of energy, iron powder will take up a little bit less space than gasoline but it'll be almost ten times heavier. It might not be suitable for powering your car, in other words. It probably won't heat your house either. But it could be ideal for industry, which is where it's being tested right now.

Researchers from TU Eindhoven have been developing iron powder as a practical fuel for the past several years, and last month they installed an iron powder heating system at a brewery in the Netherlands, which is turning all that stored up energy into beer. Since electricity can't efficiently produce the kind of heat required for many industrial applications (brewing included), iron powder is a viable zero-carbon option, with only rust left over. So what happens to all that rust? This is where things get clever, because the iron isn't just a fuel that's consumed -- it's energy storage that can be recharged. And to recharge it, you take all that Fe2O3, strip out the oxygen, and turn it back into Fe, ready to be burned again. It's not easy to do this, but much of the energy and work that it takes to pry those Os away from the Fes get returned to you when you burn the Fe the next time. The idea is that you can use the same iron over and over again, discharging it and recharging it just like you would a battery.

To maintain the zero-carbon nature of the iron fuel, the recharging process has to be zero-carbon as well. There are a variety of different ways of using electricity to turn rust back into iron, and the TU/e researchers are exploring three different technologies based on hot hydrogen reduction (which turns iron oxide and hydrogen into iron and water). [...] Both production of the hydrogen and the heat necessary to run the furnace or the reactors require energy, of course, but it's grid energy that can come from renewable sources. [...] Philip de Goey, a professor of combustion technology at TU/e, told us that he hopes to be able to deploy 10 MW iron powder high-temperature heat systems for industry within the next four years, with 10 years to the first coal power plant conversion.

In a Wall Street Journal article comparing Apple's HomePod Mini against the competition, a Google spokesperson hinted that the company is working on integrating its Chromecast streaming devices and Nest Audio speakers. The Verge reports: Being able to combine a streaming platform with a smart phone speaker makes a lot of sense for these companies. After all, customers already have all the hardware in their living room -- why not repurpose those speakers to improve the sound of your Netflix movies? Plus, there's the added bonus of inciting customers to stay within a company's ecosystem. You're more likely to buy a HomePod mini if it works with the Apple TV you already have. The ability to link smart speakers to streaming boxes is also something that both Apple and Amazon already offer.

Google's plans are extremely vague for now -- The Wall Street Journal makes no mention of which devices the company is looking to link together, when the feature will arrive, or what sort of use cases it's looking to achieve. But with Google increasingly looking to push users toward its smart home devices, making them all work better together just makes good sense.

General Motors said on Friday it was recalling 68,677 electric cars worldwide that pose a fire risk after five reported fires and two minor injuries. Reuters reports: The recall is for 2017-2019 model-year Chevrolet Bolt EVs with high voltage batteries produced at LG Chem's Ochang, Korea facility. The National Highway Traffic Safety Administration (NHTSA) last month opened a preliminary investigation into the Bolt EVs after reports of three Bolts catching fire under the rear seat while parked and unattended.

GM said the vehicles pose a fire risk when charged to full, or nearly full capacity. GM said it has developed software that will limit vehicle charging to 90% of full capacity to mitigate the risk while GM works to determine the appropriate final repair. NHTSA said in a consumer alert on Friday that Bolt owners âoeshould park their cars outside and away from homes until their vehicles have been repaired, due to a new recall for the risk of fire.â The recall includes 50,932 U.S. Bolt vehicles.

An anonymous reader quotes a report from Ars Technica: On Thursday, an Amazon AWS blogpost announced that the company has moved most of the cloud processing for its Alexa personal assistant off of Nvidia GPUs and onto its own Inferentia Application Specific Integrated Circuit (ASIC). Amazon dev Sebastien Stormacq describes the Inferentia's hardware design as follows: "AWS Inferentia is a custom chip, built by AWS, to accelerate machine learning inference workloads and optimize their cost. Each AWS Inferentia chip contains four NeuronCores. Each NeuronCore implements a high-performance systolic array matrix multiply engine, which massively speeds up typical deep learning operations such as convolution and transformers. NeuronCores are also equipped with a large on-chip cache, which helps cut down on external memory accesses, dramatically reducing latency and increasing throughput."

When an Amazon customer -- usually someone who owns an Echo or Echo dot -- makes use of the Alexa personal assistant, very little of the processing is done on the device itself. [...] According to Stormacq, shifting this inference workload from Nvidia GPU hardware to Amazon's own Inferentia chip resulted in 30-percent lower cost and 25-percent improvement in end-to-end latency on Alexa's text-to-speech workloads. Amazon isn't the only company using the Inferentia processor -- the chip powers Amazon AWS Inf1 instances, which are available to the general public and compete with Amazon's GPU-powered G4 instances. Amazon's AWS Neuron software development kit allows machine-learning developers to use Inferentia as a target for popular frameworks, including TensorFlow, PyTorch, and MXNet.

Samsung LSI today announced the new Exynos 1080 SoC (system on chip), a successor to last year's Exynos 980. This year's 1080 is seemingly positioned a little above the 980 in terms of performance as we're seeing some quite notable gains in features compared to the 980. From a report: It's to be remembered that this is a "premium" SoC, meaning it's not a flagship SoC, but it's also not quite a mid-range SoC, fitting itself in-between those two categories, a niche which has become quite popular over the last 1-2 years. The new SoC is defined by having a new 1+3+4 CPU configuration, as reasonably large GPU, and full 5G connectivity integrated, and is the first publicly announced SoC to be manufactured on Samsung's new 5LPE process node. On the CPU side of things, this is the first time we've seen Samsung adopt a 1+3+4 CPU configuration, now adopting the Cortex-A78 architecture on the part of the performance cores. One core is clocked at 2.8GHz while the three others are running at 2.6GHz. Qualcomm had first introduced such a setup and it seems it's become quite popular as it gives the benefit of both performance and power efficiency. The four big cores are accompanied by four Cortex-A55 cores at 2.0GHz.

schwit1 shares a report from Phys.Org: Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3-D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed. This form of technology, known as "cold spray," results in mechanically robust, porous structures that are 40% stronger than similar materials made with conventional manufacturing processes. The structures' small size and porosity make them particularly well-suited for building biomedical components, like replacement joints.

The team's paper, "Solid-State Additive Manufacturing of Porous Ti-6Al-4V by Supersonic Impact," published Nov. 9 in Applied Materials Today. "If we make implants with these kind of porous structures, and we insert them in the body, the bone can grow inside these pores and make a biological fixation," Moridi said. "This helps reduce the likelihood of the implant loosening. And this is a big deal. There are lots of revision surgeries that patients have to go through to remove the implant just because it's loose and it causes a lot of pain." Moridi added: "We only focused on titanium alloys and biomedical applications, but the applicability of this process could be beyond that. Essentially, any metallic material that can endure plastic deformation could benefit from this process. And it opens up a lot of opportunities for larger-scale industrial applications, like construction, transportation and energy."

A consortium led by Rolls Royce has announced plans to build up to 16 mini-nuclear plants in the UK. The BBC reports: It says the project will create 6,000 new jobs in the Midlands and the North of England over the next five years. The prime minister is understood to be poised to announce at least 200 million pounds for the project as part of a long-delayed green plan for economic recovery. Rolls argues that as well as producing low-carbon electricity, the concept could become a new export industry.

The company's UK "small modular reactor" (SMR) group includes the National Nuclear Laboratory and the building company Laing O'Rourke. The government says new nuclear is essential if the UK is to meet its target of reaching net zero emissions by 2050 -- where any carbon released is balanced out by an equivalent amount absorbed from the atmosphere. But there is a nuclear-sized hole opening up in the energy network. Six of the UK's seven nuclear reactor sites are due to go offline by 2030 and the remaining one, Sizewell B, is due to be decommissioned in 2035. Together they account for around 20% of the country's electricity.

Each plant would produce 440 megawatts of electricity -- roughly enough to power Sheffield -- and the hope is that, once the first few have been made, they will cost around 2 billion pounds each. The consortium says the first of these modular plants could be up and running in 10 years, after that it will be able to build and install two a year. By comparison, the much larger nuclear plant being built at Hinkley Point in Somerset is expect to cost some 22 billion pounds but will produce more than 3 gigawatts of electricity -- over six times as much.

Anmar Frangoul writes via CNBC: Work has started on a liquid air energy storage site in the northwest of England, with the team behind the project stating it will be one of the largest energy storage systems in Europe. Highview Power's 50 megawatt facility in Greater Manchester will harness technology that uses something called "air liquefaction." The system involves a number of steps: excess or off peak electricity powers an air liquefier. This cleans, compresses then cools ambient air, turning it into a liquid at -196 degrees Celsius (around -320 Fahrenheit). According to the company, this liquid air is "stored at low pressure and later heated and expanded to drive a turbine and generate power."

The technology being deployed by Highview Power stems from an idea developed by Peter Dearman, the brains behind the concept of a "liquid air engine." According to the U.K. government, Dearman -- who's been described by the BBC as a "self-taught backyard inventor" -- worked alongside a team from the University of Leeds to develop the idea of "using air as a form of energy storage" when compressed and liquefied. The new site, which is scheduled to open in 2023, will be operated by Highview Power in partnership with another firm called Carlton Power.

An anonymous reader quotes a report from Tom's Hardware: Western Digital is one of the most vocal proponents of the Zoned Namespaces (ZNS) storage initiative, so it is not surprising that the company this week became the first SSD maker to start sampling of a ZNS SSD. When used properly, the Ultrastar DC ZN540 drive can replace up to four conventional SSDs, provide higher performance and improve quality of service (QoS).

ZNS SSDs have a number of advantages over traditional block-based SSDs. For one, they place data sequentially into zones and have better control over write amplification, since the software 'knows' what it is dealing with. This means that ZNS SSDs don't need as much overprovisioning as traditional enterprise drives. Many enterprise drives rated for 3DWPD (drive writes per day) reserve up to 28% of their raw capacity for overprovisioning. ZNS needing as little as a tenth of that significantly increases usable SSD capacity. Second, since ZNS manages large zones rather than a bunch of 4KB blocks and doesn't need to perform garbage collection as often as traditional SSDs, it also improves real-world read and write performance. Finally, ZNS substantially reduces DRAM requirements.

szczys writes: When the Raspberry Pi 400 (a keyboard form-factor single board computer) was released last week, the company hinted at overclocking. Testing has now shown that the heat spreader used in that design does an excellent job. The chip was already clocked at 1.8 GHz, versus the stock 1.5 GHz in the original Raspberry Pi 4 Model B board. But it can be safely overclocked to 2.15 GHz, as can the Compute Module 4 with an adequate heat sink.

At 2.0 GHz, the Pi 400 got up above 60 C and showed signs of continuing to warm up even after 50 minutes, but it was nowhere near throttling. So I tried 2.2 GHz, at which speed the CPU refused to boot entirely. Backing down to 2.15 GHz, it ran just fine, so I left it for three hours. It settled in at a cozy 62.5 C, which is warm, but well within specs.

I ran the CM4 with the larger heatsink at 1.8 GHz to give some basis for comparison to the cheap heatsinks. What a big difference a big hunk of aluminum makes! It settled in at a comfortable 68 C or so. Even pushing it up to 2.15 GHz and leaving it for a couple hours, it stayed just a hair below 70C (158F) -- a safe margin on the throttling threshold -- and only a few degrees warmer than that huge heat spreader in the Pi 400.

Come June 1, 2021, Google will change its storage policies for free accounts -- and not for the better. Basically, if you're on a free account and a semi-regular Google Photos user, get ready to pay up next year and subscribe to Google One. From a report: Currently, every free Google Account comes with 15 GB of online storage for all your Gmail, Drive and Photos needs. Email and the files you store in Drive already counted against those 15 GB, but come June 1, all Docs, Sheets, Slides, Drawings, Forms or Jamboard files will count against the free storage as well. Those tend to be small files, but what's maybe most important here, virtually all of your Photos uploads will now count against those 15 GB as well. That's a bid deal because today, Google Photos lets you store unlimited images (and unlimited video, if it's in HD) for free as long as they are under 16MP in resolution or you opt to have Google degrade the quality. Come June of 2021, any new photo or video uploaded in high quality, which currently wouldn't count against your allocation, will count against those free 15 GB. [...] In addition to these storage updates, there's a few additional changes worth knowing about. If your account is inactive in Gmail, Drive or Photos for more than two years, Google 'may' delete the content in that product.

An anonymous reader quotes a report from TechCrunch: SoftBank Group Corp. is in talks to sell robot maker Boston Dynamics to Hyundai, people familiar with the matter said. Proposed terms of the deal would give the South Korean automaker control of the robotics company in a transaction valued at as much as $1 billion, said one of the people, all of whom asked not to be identified because the discussions are private. The terms have yet to be finalized, and the deal could fall apart, said the people.

A sale of Boston Dynamics would mark another twist in the trajectory of a company that spun out of the Massachusetts Institute of Technology in the early 1990s and operated independently until Google bought it in 2013. It was sold again in 2017, that time to SoftBank. At times, Boston Dynamics has functioned more like a research organization than a business, churning out machines that are technologically advanced and whimsical but unprofitable. That includes Spot, a maneuverable dog-like robot. Videos of its creations regularly rack up millions of views on YouTube; however, the company has said it is not currently generating profits. By contrast, Hyundai makes highly practical industrial robots intended for factory use.

Dish Network announced that it will permanently shut down all of Sling Media's Slingbox services and end support for the devices in two years, at which point they'll no longer work. Variety reports: On Monday, Dish's Sling Media unit announced that Slingbox servers will be permanently taken offline 24 months from Nov. 9, 2020. "Until then, most Slingbox models will continue to work normally, but the number of supported devices for viewing will steadily decrease as versions of the SlingPlayer apps become outdated and/or lose compatibility," the company said in a message posted Monday.

In an FAQ about the shutdown, Dish said Slingbox is being discontinued because "We've had to make room for new innovative products so that we can continue to serve our customers in the best way possible." Sling will not be releasing any new products; most authorized resellers have been out of stock of the Slingbox devices "for a couple years," according to the company. Sling Media was acquired by EchoStar in 2007 for $380 million, which at the time was Dish's parent company. Years before Netflix became a streaming powerhouse, the Slingbox "place-shifting" devices let customers watch pay-TV channels over the internet. But the products never became a mainstream category in the way streaming-media players like Roku and Amazon's Fire TV have.

Micron has announced it's shipping 176-layer TLC NAND flash memory to customers, a move that portends larger, faster and even cheaper SSD drives for all. From a report: The company said its 5th-gen 3D NAND memory should put its density about 40 percent higher than its nearest competitors, which are using 128-layer NAND. Micron said read and write latencies are reduced by 35 percent compared to its 96-layer NAND, and by 25 percent compared its 128-layer NAND. Micron isn't the only NAND memory manufacturer that has 176 layers, but it is the first to start volume shipments. The Micron NAND is TLC, or three-bits per cell, and is said to have 33 percent faster transfer rates, as well as a 35 percent improvement in read and write latencies. And because it's TLC NAND instead of QLC, the new memory should offer better drive endurance, too. The 176-layer design comes from stacking two 88-layer stacks together, which isn't a new thing for Micron. You might think that's a trick, but the end result is still the same: far better density for larger drives. Micron said the new 176-layer NAND is about as thick as one-fifth of a sheet of printer paper, and works out to be as thick its previous 64-layer NAND despite having more than twice as many layers. In the end, this will lead to larger SSDs and potentially cheaper ones, too.

Apple has introduced the new M1 chip that will power its new generation of Arm-based Macs. It's a 5nm processor, just like the A14 Bionic powering its latest iPhones. From a report: Apple says the new processor will focus on combining power efficiency with performance. It has an eight-core CPU, which Apple says offers the world's best performance per watt of an CPU. Apple says it delivers the same peak performance as a typical laptop CPU at a quarter of the power draw. It says this has four of the world's fastest CPUs cores, paired with four high-efficiency cores. It pairs this with up to an eight-core GPU, which Apple claims offers the world's fastest integrated graphics, and a 16-core Neural Engine. In addition, the M1 processor has a universal memory architecture, a USB 4 controller, media encode and decode engines, and a host of security features. These include hardware-verified secure boot, encryption, and run-time protections.

fahrbot-bot shares a report from CNN: A team of physicists at a university in the Netherlands have 3D-printed a microscopic version of the USS Voyager, an Intrepid-class starship from Star Trek. The miniature Voyager, which measures 15 micrometers (0.015 millimeters) long, is part of a project researchers at Leiden University conducted to understand how shape affects the motion and interactions of microswimmers.

Microswimmers are small particles that can move through liquid on their own by interacting with their environment through chemical reactions. The platinum coating on the microswimmers reacts to a hydrogen peroxide solution they are placed in, and that propels them through the liquid. "By studying synthetic microswimmers, we would like to understand biological microswimmers," Samia Ouhajji, one of the study's authors, told CNN. "This understanding could aid in developing new drug delivery vehicles; for example, microrobots that swim autonomously and deliver drugs at the desired location in the human body." In their project, the physicists also printed shapes like boats, trimers and helices, with each object's shape affecting their swimming behaviors.

Remembrance Sunday is the day of commemoration for British and Commonwealth servicemen, and the head of the British Armed Forces marked the occasion with a special interview on Sky News.

And he shared a thoughtful answer when asked whether the army might try to recruit fewer soldiers. "[W]hat I'm hinting at is that we need to be thinking about how we measure effects in a different way. I mean I suspect we can have an army of 120,000 of which 30,000 might be robots, who knows. But the answer is we need to open our minds to perhaps numbers not determining what we should be doing but rather the effect that we can achieve, is really what we should be looking for."

The armed forces are playing a key role in the government's response to the pandemic, with some 2,000 personnel deployed to Liverpool to help with a mass coronavirus testing programme for the city. "I suspect if that works successfully we might find there are other areas where we need to help in a similar sort of fashion," General Carter said. He said using the military to take over the entire coronavirus testing programme was an option but added that he had confidence in the current set-up at the moment.
The Guardian focused on the robots: Thirty thousand "robot soldiers" could form an integral part of the British army in the 2030s, working alongside humans in and around the frontline, the head of the armed forces said in a television interview on Sunday...

All Britain's armed forces have been engaged in a string of research projects involving small drones or remotely powered land or underwater vehicles, some of which are armed and others for reconnaissance. The Ministry of Defence says its policy is that only humans will be able to fire weapons, although there is growing concern about the potential danger of unrestricted robot warfare, led by the Campaign to Stop Killer Robots.

Technology under development includes the i9 drone, which is powered by six rotors and carries two shotguns. Remotely operated, it is intended to be used to storm buildings, typically an urban warfare situation that generates some of the highest casualties.
