The nonprofit Habitat for Humanity uses volunteer labor to build homes with affordable mortgages for families in need (who also invest hundreds of hours of their own labor) — or to renovate or repair/improve existing homes.

But this week saw them delivering something new: a 3D-printed home, built with giant 3D printers from a company called Alquist).

CNN reports: The 1,200-square-foot home has three bedrooms, two full baths and was built from concrete. The technology allowed the home to be built in just 12 hours, which saves about four weeks of construction time for a typical home....

The concrete used in the house's 3D construction has many long-term benefits, such as the ability to retain temperature [reducing heating and cooling costs] and withstand natural disasters, like tornadoes and hurricanes. [It also reduced building costs by an estimated 15% per square foot.] Stringfield's home also includes a personal 3D printer that will allow her to reprint anything she may need, "everything from electrical outlet to trim to cabinet knobs," Janet V. Green, CEO of Habitat for Humanity Peninsula and Greater Williamsburg, told CNN.

While this is the first 3D home for Habitat for Humanity in the U.S., it certainly won't be the last. Green told CNN it hopes to continue partnering and developing the technology used with the printing. "We would love to build more with this technology, especially because it's got that long-term savings for the homeowners," Green said.
The house will also have "smart building" applications that track data on the indoor environment through a proprietary Virginia Tech system that uses a Raspberry Pi, according to a statement from Habitat for Humanity.

And the house will be outfitted with solar panels, "for even more cost savings after the family moves in."

"Your laptop is way more powerful than you might realize," writes long-time Slashdot reader fahrbot-bot.

"People often rhapsodize about how much more computer power we have now compared with what was available in the 1960s during the Apollo era. Those comparisons usually grossly underestimate the difference."

Rodney Brooks, emeritus professor of robotics at MIT (and former director of their AI Lab and CSAIL) explains in IEEE Spectrum: By 1961, a few universities around the world had bought IBM 7090 mainframes. The 7090 was the first line of all-transistor computers, and it cost US $20 million in today's money, or about 6,000 times as much as a top-of-the-line laptop today. Its early buyers typically deployed the computers as a shared resource for an entire campus. Very few users were fortunate enough to get as much as an hour of computer time per week.

The 7090 had a clock cycle of 2.18 microseconds, so the operating frequency was just under 500 kilohertz. But in those days, instructions were not pipelined, so most took more than one cycle to execute. Some integer arithmetic took up to 14 cycles, and a floating-point operation could hog up to 15. So the 7090 is generally estimated to have executed about 100,000 instructions per second. Most modern computer cores can operate at a sustained rate of 3 billion instructions per second, with much faster peak speeds. That is 30,000 times as fast, so a modern chip with four or eight cores is easily 100,000 times as fast.

Unlike the lucky person in 1961 who got an hour of computer time, you can run your laptop all the time, racking up more than 1,900 years of 7090 computer time every week....

But, really, this comparison is unfair to today's computers. Your laptop probably has 16 gigabytes of main memory. The 7090 maxed out at 144 kilobytes. To run the same program would require an awful lot of shuffling of data into and out of the 7090 — and it would have to be done using magnetic tapes . The best tape drives in those days had maximum data-transfer rates of 60 KB per second. Although 12 tape units could be attached to a single 7090 computer, that rate needed to be shared among them. But such sharing would require that a group of human operators swap tapes on the drives; to read (or write) 16 GB of data this way would take three days. So data transfer, too, was slower by a factor of about 100,000 compared with today's rate.

So now the 7090 looks to have run at about a quadrillionth (10 ** -15) the speed of your 2021 laptop. A week of computing time on a modern laptop would take longer than the age of the universe on the 7090.

With some time on their hands, long-time Slashdot reader shanen began exploring the question: How many files does my Windows 10 computer have?

But then they realized "It would also be interesting to compare the weirdness on other OSes..." Here are the two data points in front of me:

(1) Using the right click on properties for all of the top-level folders on the drive (including the so-called hidden folders), it quickly determined that there are a few hundred thousand files in those folders (and a few hundred thousand subfolders). That's already ridiculous, but the expected par these days. The largest project I have on the machine only has about 3,000 files, and that one goes back many years... (My largest database only has about 5,000 records, but it's just a few files.)

(2) However, I also decided to take a look with Microsoft's malicious software removal tool and got a completely different answer. For twisted grins, I had invoked the full scan. It's still running a day later and has already passed 10 million files. Really? The progress bar indicates about 80% finished? WTF?

Obviously there is some kind of disagreement about the nature of "file" here. I could only think of one crazy explanation, but my router answered "No, the computer is not checking all of the files on the Internet." So I've already asked the specific question in three-letter form, but the broader question is about the explosive, perhaps even cancerous, "population growth" of files these days.
Maybe we can all solve this mystery together. So use the comments to share your own answers and insights.

How many files are on your computer?

Heating plasma fuel to over 100 million degrees Celsius to create inexpensive and unlimited zero-emissions electricity "has been compared to everything from a holy grail to fool's gold..." writes the Boston Globe, "or an expensive delusion diverting scarce money and brainpower from the urgent needs of rapidly addressing climate change." [N]ow, after breakthroughs this year at MIT and elsewhere, scientists — and a growing number of deep-pocketed investors — insist that fusion is for real and could start sending power to electricity grids in about a decade.

To prove that, Commonwealth Fusion Systems, an MIT spinoff in Cambridge, is using a whopping $1.8 billion it raised in recent months from investors such as Bill Gates, Google, and a host of private equity firms to build a prototype of a specially designed fusion reactor on a former Superfund site in Devens. A host of excavators, backhoes, and other heavy machinery are clearing land there and laying concrete foundations on 47 acres of newly acquired land. "It may sound like science fiction, but the science of fusion is real, and the recent scientific advancements are game-changing," said Dennis Whyte, director of MIT's Plasma Science and Fusion Center and cofounder of Commonwealth Fusion Systems. "These advancements aren't incremental; they are quantum leap improvements. . . . We're in a new era of actually delivering real energy systems...."

There are now at least 35 companies trying to prove that fusion can be a practical power source, most of them established in the past decade, according to the three-year-old Fusion Industry Association. The promise of fusion was buoyed with significant developments this year. In May, scientists in China used their own specially designed tokamak to sustain a fusion reaction of 120 million degrees Celsius for 101 seconds, the longest on record. In September, Whyte's team at MIT and his colleagues at Commonwealth Fusion Systems demonstrated that, while using relatively low-cost materials that don't require a large amount of space, they could create the most powerful magnetic field of its kind on Earth, a critical component of the prototype reactor they're building in Devens.

"We have come a long way," said Bob Mumgaard, CEO of Commonwealth Fusion Systems, who compared their advance to similar breakthroughs that made flight possible. "We're a pretty conservative science bunch, but we're pretty confident." With some $2 billion raised in recent years — more than any of the other fusion startups — his company is racing to prove that their prototype, called SPARC, will produce more energy than it consumes in 2025. If they succeed, the company plans to start building their first power plant several years afterward. Ultimately, he said, their goal is to help build 10,000 200-megawatt fusion power plants around the world, enough to replace nearly all fossil fuels. "This is a solution that can scale to the size of the problem that decarbonization requires," he said.
Phil Warburg, a senior fellow at Boston University's Institute for Sustainable Energy, disagrees. "Fusion has been an elusive fantasy for a half-century or more," he tells the Boston Globe. "Along with the technical hurdles, the environmental downsides have not been seriously examined, and the economics are anything but proven... The current wave of excitement about fusion comes at a time when we've barely begun to tap the transformative potential of solar, wind, storage, and energy efficiency — all known to be technically viable, economically competitive, and scalable today. The environmental advocacy community needs to focus on vastly expanding those clean-energy applications, leaving fusion to the scientists until they've got something much more credible to show for their efforts."

But Elizabeth Turnbull Henry, president of the Environmental League of Massachusetts rejected the argument that fusion research detracts from investments in renewables as a "false choice.... We're at a very different moment now, and it's good to have a lot of different horses in the race."

The also article notes that officials at America's Nuclear Regulatory Commission told them federal officials are already holding meetings to discuss how they'd regulate fusion reactors.

An anonymous reader quotes a report from HotHardware: During a recent earnings call to discuss its quarterly earnings, Micron explained that the reason DDR5 demand is "significantly exceeding supply" is because suppliers are having a rough time sourcing non-memory components. The insinuation is that Micron can make enough DDR5 chips to satisfy demand, it's just that the other parts that comprise a memory module are not as readily available. The good news is, this should ease a bit next year.

"Across the PC industry, demand for DDR5 products is significantly exceeding supply due to non-memory component shortages impacting memory suppliers' ability to build DDR5 modules. We expect these shortages to moderate through 2022, enabling bit shipments of DDR5 to grow to meaningful levels in the second half of calendar 2022," Micron CEO and president Sanjay Mehrotra said during the call. Micron did not get into specifics about the components that are in short supply, but it likely means power management ICs (PMICs), voltage regulating modules (VRMs), and possibly even printed circuit boards (PCBs) that are strained right now. It's those first two parts that are the most likely culprits, though. DDR5 employs both components rather than continue to have the motherboard handle those chores, and it will take some time for the industry to adjust.

Researchers have developed a rechargeable lithium-ion battery in the form of an ultra-long fiber that could be woven into fabrics. From a report: In a proof of concept, the team behind the new battery technology has produced the world's longest flexible fiber battery, 140 meters long, to demonstrate that the material can be manufactured to arbitrarily long lengths. The work is described today in the journal Materials Today. [...] The new fiber battery is manufactured using novel battery gels and a standard fiber-drawing system that starts with a larger cylinder containing all the components and then heats it to just below its melting point. The material is drawn through a narrow opening to compress all the parts to a fraction of their original diameter, while maintaining all the original arrangement of parts.

While others have attempted to make batteries in fiber form, [says MIT postdoc Tural Khudiyey, a lead author on the paper], those were structured with key materials on the outside of the fiber, whereas this system embeds the lithium and other materials inside the fiber, with a protective outside coating, thus directly making this version stable and waterproof. This is the first demonstration of a sub-kilometer long fiber battery which is both sufficiently long and highly durable to have practical applications, he says. The fact that they were able to make a 140-meter fiber battery shows that "there's no obvious upper limit to the length. We could definitely do a kilometer-scale length," he says.

The 140-meter fiber produced so far has an energy storage capacity of 123 milliamp-hours, which can charge smartwatches or phones, he says. The fiber device is only a few hundred microns in thickness, thinner than any previous attempts to produce batteries in fiber form. In addition to individual one-dimensional fibers, which can be woven to produce two-dimensional fabrics, the material can also be used in 3D printing or custom-shape systems to create solid objects, such as casings that could provide both the structure of a device and its power source. To demonstrate this capability, a toy submarine was wrapped with the battery fiber to provide it with power. Incorporating the power source into the structure of such devices could lower the overall weight and so improve the efficiency and range they can achieve.

An anonymous reader quotes a report from CNBC: The Hornsea 2 offshore wind farm has produced its first power, Danish energy firm Orsted has said, with the announcement representing a significant milestone in the facility's development. Situated in waters around 89 kilometers off the U.K.'s east coast, the scale of Hornsea 2 is considerable. Spread across an area of 462 km2, it will use 165 turbines from Siemens Gamesa and boast a capacity of more than 1.3 gigawatts. The company says it will power "well over" 1.3 million homes when finished.

The project generated its first power late on Saturday night. According to Orsted, Hornsea 2 will assume the title of "world's largest operating offshore wind farm" once fully operational in 2022. The firm has also described Hornsea 2 as the "world's biggest offshore wind farm." That accolade, the company says, is currently held by Hornsea 1, the "sibling project" of Hornsea 2. "Together, the two projects will be capable of providing enough power for well over 2.3 million homes," Orsted said on Monday. In a statement issued alongside the company's announcement, Patrick Harnett, senior program director for Hornsea 2, said: "From here, we have the finishing line in sight as we install the remaining turbines and continue testing, commissioning, and energizing our wind farm into the new year."

New York-based firm Pliant Energy Systems is building a marine system reminiscent of the cuttlefish with its rippling underwater motion, a report from The Economist reveals. The company's biomimetic machine, called Velox, is based on the principle that propellers are nowhere near as efficient as the fins of sea creatures that are prevalent in nature. Interesting Engineering reports: Unlike propellers, fins and flippers can extend around a sea creature, meaning more propulsion without the need for a large protruding propeller that could get caught or damaged by hitting the seabed. Fins are also flexible, meaning that if they do come in contact with any other object in the sea, they are less likely to get damaged. In an interview with The Economist, an ex-marine biologist and founder of Pliant Energy Systems, Benjamin Pietro Filardo, explained how he is designing submersible machines that are propelled using flexible fin-like materials. He said Velox will produce approximately three times as much thrust per unit energy as the average propeller of a small boat. The system can travel underwater and even come out onto land, using its fins almost like robotic legs. The video below shows Velox skating on ice and swimming in a pool.

Filardo showed his new design to America's Office of Naval Research, leading them to commission a new iteration, called C-Ray, that will be faster and lighter than Velox. C-Ray also won't be tethered, unlike Velox, which is currently controlled via a cable. Autonomous swarms of the machine could eventually be used for missions such as undersea patrols, mine removal, and deepsea exploration and monitoring. [...] Filardo said the system has great potential for scalability, giving the blue whale as an example of a massive sea mammal that uses fins for propulsion. Impressively, he also revealed that he is also working on a concept that would allow his system to moor itself, and then use the undulations of its fins, thanks to the sea current, to recharge. A lot of testing is still needed, but if Filardo's system delivers on its promise, we might eventually see giant mechanical sea beasts silently gliding through the oceans.

An anonymous reader quotes a report from Popular Science: The Biden administration has pledged to create a carbon-free energy sector by 2035, but because renewable resources generate only around 19 percent of US electricity as of 2020, climate experts warn that our transition to a green grid future needs to speed up. A group of researchers at Stanford led by Mark Jacobson, professor of civil and environmental engineering, has set out to prove that a 100 percent renewable energy grid by 2050 is not only feasible but can be done without any blackouts and at a lower cost than the existing grid. Jacobson is the lead author of a new paper, published in Renewable Energy, which argues that a complete transition to renewable energy -- defined as wind, water, and solar energy -- would benefit the US as a whole and individuals by saving costs, creating jobs, and reducing air pollution and carbon emissions.

They modeled how wind turbines, tidal turbines, geothermal and hydroelectric power plants, rooftop and utility photovoltaic panels, and other sources could generate energy in 2050. A host of different sources powered these projections: Jacobson used data from a weather-climate-air pollution model he first built in 1990, which has been used in numerous simulations since. Individual state and sector energy consumption was taken from the Energy Information Administration. Current fossil fuel energy sources were converted to electric devices that are powered by wind, water, and solar. This was then used to create projections for energy use in 2050. Time-dependent energy supply was matched with demand and storage in a grid integration model for every 30 second interval in 2050 and 2051. The study authors analyzed US regions and countrywide demand until the model produced a solution with what the authors called zero-load loss -- meaning, essentially, no blackouts with 100 percent renewable energy and storage. According to Jacobson, no other study is conducting this kind of modeling, which is unique in part because it checks conditions for any simulation every 30 seconds.

As the cost of renewables falls, researchers predict power companies and consumers will migrate to using renewables. Solar and wind are already half the cost of natural gas. Policy may also motivate adoption -- or hinder it. While the current administration has set out goals for a renewable energy grid, new permits for gas and drilling in the Gulf of Mexico counteract those same efforts. [...] The researchers quantified these benefits by looking at private costs, such as those to individuals or corporations, and social ones, which also include health and climate costs. Zero-emissions leads to few air pollution related deaths and illness, and a reduced toll on the healthcare system. [...] The model cannot address emissions from things like long-distance shipping or aviation, though the authors argue that green hydrogen could be a possible alternative to explore. They did not include nuclear energy or carbon capture, which [Anna-Katharina von Krauland, a PhD candidate in the Atmosphere/Energy program at Stanford and a co-author of the paper] views as "distractions from getting to 100 percent renewable energy as quickly as possible" because the technologies are costly, unproven, or lacking in their promises. "The best path forward would be to invest in what we know works as quickly as we can," she says -- such as wind, water, and solar energy.

The months-long project demonstrates the physics behind the CPUs we take for granted. From a report: Computer chips have become so tiny and complex that it's sometimes hard to remember that there are real physical principles behind them. They aren't just a bunch of ever-increasing numbers. For a practical (well, virtual) example, check out the latest version of a computer processor built exclusively inside the Minecraft game engine. Minecraft builder "Sammyuri" spent seven months building what they call the Chungus 2, an enormously complex computer processor that exists virtually inside the Minecraft game engine. This project isn't the first time a computer processor has been virtually rebuilt inside Minecraft, but the Chungus 2 (Computation Humongous Unconventional Number and Graphics Unit) might very well be the largest and most complex, simulating an 8-bit processor with a one hertz clock speed and 256 bytes of RAM. Minecraft processors use the physics engine of the game to recreate the structure of real processors on a macro scale, with materials including redstone dust, torches, repeaters, pistons, levers, and other simple machines. For a little perspective, each "block" inside the game is one virtual meter on each side, so recreating this build in the real world would make it approximately the size of a skyscraper or cruise ship.

Slashdot reader SoftwareArtist shares an announcement from a Stanford University institute for environmental studies. "For some, visions of a future powered by clean, renewable energy are clouded by fears of blackouts driven by intermittent electricity supplies," the announcement begins.

"Those fears are misplaced, according to a new Stanford University study that analyzes grid stability under multiple scenarios in which wind, water and solar energy resources power 100% of U.S. energy needs for all purposes." "This study is the first to examine grid stability in all U.S. grid regions and many individual states after electrifying all energy and providing the electricity with only energy that is both clean and renewable," said study lead author Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford... Imagine all cars and trucks were powered with electric motors or hydrogen fuel cells, electric heat pumps replaced gas furnaces and water heaters and wind turbines and solar panels replaced coal and natural gas power plants. The study envisions those and many more transitions in place across the electricity, transportation, buildings and industrial sectors in the years 2050 and 2051...

Interconnecting larger and larger geographic regions made power supply smoother and costs lower because it upped the chances of available wind, sun and hydro power availability and reduced the need for extra wind turbines, solar panels and batteries. A significant finding of the study was that long-duration batteries were neither needed nor helpful for keeping the grid stable. Instead, grid stability could be obtained by linking together currently available batteries with storage durations of four hours or less. Linking together short-duration batteries can provide long-term storage when they are used in succession. They can also be discharged simultaneously to meet heavy peaks in demand for short periods. In other words, short-duration batteries can be used for both big peaks in demand for short periods and lower peaks for a long period or anything in-between.
Other findings:

• Cleaner air would spare about 53,200 people from pollution-related deaths every year. It would also spare millions more from pollution-related illnesses. Total estimated health costs saved each year: $700 billion.
• Building and operating a completely renewable grid may create 4.7 million long-term jobs.

• Per capita household energy costs were nearly 63% less.

• New electricity generators would occupy about 0.84% of U.S. land (versus roughly 1.3% occupied today by the fossil fuel industry).

Google has announced a new policy for cloud storage service Drive, which will soon begin to restrict access to files deemed to be in violation of the company's policies. TechRadar reports: As explained in a new blog post, Google will take active steps to identify files hosted on its platform that are in breach of either its Terms of Service or abuse program policies. These files will be flagged to their owner and restricted automatically, which means they can no longer be shared with other people, and access will be withdrawn from everyone but the owner. "This will help ensure owners of Google Drive items are fully informed about the status of their content, while also helping to ensure users are protected from abusive content," the company explained.

According to Google, the motive behind the policy change is to shield against the abuse of its services. This broad catchall encompasses cybercriminal activity (like malware hosting, phishing etc.), hate speech, and content that might endanger children, but also sexually explicit material. "We need to curb abuses that threaten our ability to provide these services, and we ask that everyone abide by [our policies] to help us achieve this goal," states Google in its policy document. "After we are notified of a potential policy violation, we may review the content and take action, including restricting access to the content, removing the content, and limiting or terminating a user's access to Google products." Google goes on to say that it may make "exceptions based on artistic, educational, documentary or scientific considerations." As noted by TechRadar, "there is a system to request a review of a decision if someone feels a file has been restricted unfairly, but it's unclear how the process will be handled on Google's end and how long it might take."

IBM and Samsung have announced their latest advance in semiconductor design: a new way to stack transistors vertically on a chip (instead of lying flat on the surface of the semiconductor). The Verge reports: The new Vertical Transport Field Effect Transistors (VTFET) design is meant to succeed the current FinFET technology that's used for some of today's most advanced chips and could allow for chips that are even more densely packed with transistors than today. In essence, the new design would stack transistors vertically, allowing for current to flow up and down the stack of transistors instead of the side-to-side horizontal layout that's currently used on most chips. Vertical designs for semiconductors have been a trend for a while (FinFET already offers some of those benefits); Intel's future roadmap also looks to move in that direction, too, although its initial work focused on stacking chip components rather than individual transistors. It makes sense, after all: when you've run out of ways to add more chips in one plane, the only real direction (other than physically shrinking transistor technology) is to go up.

While we're still a ways away from VTFET designs being used in actual consumer chips, the two companies are making some big claims, noting that VTFET chips could offer a "two times improvement in performance or an 85 percent reduction in energy use" compared to FinFET designs. And by packing more transistors into chips, IBM and Samsung claim that VTFET technology could help keep Moore's law's goal of steadily increasing transistor count moving forward. IBM and Samsung are also citing some ambitious possible use cases for the new technology, raising the idea of "cell phone batteries that could go over a week without being charged, instead of days," less energy-intensive cryptocurrency mining or data encryption, and even more powerful IoT devices or even spacecraft.

Leading chip-maker Intel has stressed that building Metaverse -- at scale and accessible by billions of humans in real time -- will require a 1,000-times increase in computational efficiency from what we have today. Insider reports: Raja Koduri, a senior vice president and head of Intel's Accelerated Computing Systems and Graphics Group, said that our computing, storage and networking infrastructure today is simply not enough to enable this Metaverse vision, being popularized by Meta (formerly Facebook) and other companies. "We need several orders of magnitude more powerful computing capability, accessible at much lower latencies across a multitude of device form factors," Koduri said in a blog post. To enable these capabilities at scale, the entire plumbing of the internet will need major upgrades, he added.

An anonymous reader quotes a report from The Register: Social media and search engine operators in Japan will be required to specify the countries in which users' data is physically stored, under a planned tweak to local laws. The Ministry of Internal Affairs and Communications this week announced it plans to submit the revision to the Telecommunications Business Law early next year. The amendment, if passed, requires search engines, social media operators and mobile phone companies with over 10 million Japanese users to disclose where in the world they store data, and identify any foreign subcontractors that can access the data. The proposed law applies to overseas companies that operate in Japan -- meaning the likes of Twitter and Facebook will need to disclose their storage choices publicly. Oddly, search engines that just cover travel and food get a pass and don't have to comply. "The move is in part a reaction to Japan's hugely popular homegrown freeware instant communication app, LINE, which had several recent snafus related to data storage and protection," the report adds.

In March, the Japanese government said it was investigating LINE's parent company after a local newspaper reported that engineers at one of the app's Chinese contractors accessed the messages and personal details of LINE users. And just a couple weeks ago, the company announced that around 133,000 users' payment details were mistakenly published on GitHub between September and November of this year.

On Tuesday, Dell announced a new design concept for a laptop that's long lived, easy to take apart and fix, and takes a smaller toll on the climate. The Verge reports: Called "Concept Luna," the proof-of-concept laptop dreamed up by Dell's design team has a number of unusual features that are intended to make repair and maintenance easy. No screwdrivers or glue solvents are needed to pry loose a broken keyboard or peel off a cracked screen; both components simply pop free after a pair of keystones holding them in place are removed. The entire system contains far fewer screws than a typical Dell laptop, reducing the time needed to replace components. And you'll never have to worry about replacing a broken fan, because there isn't one: a shrunken-down motherboard placed in the top cover allows the laptop to passively cool itself.

Dell design strategist Drew Tosh described Luna as a "front end concept" intended to "solve some of the larger problems we're trying to get ahead of in the future," namely e-waste and climate change. A laptop that is easy to repair and upgrade is less likely to be replaced with a new one that takes yet more energy and resources to produce. When that computer eventually does stop working, parts can be harvested to live on in other machines rather than winding up as toxic trash in landfills. [...] "We're really focused on reuse and recycle," Tosh told The Verge. "And really, it would be more like reuse, reuse, reuse, and recycle only when we really have to." So far, only several prototype versions of this laptop exist. But the design Dell is showing off is as sleek and portable as any laptop in the company's current lineup.

Other ideas in Concept Luna are more focused on the climate impact of electronics. The aluminum in the chassis is smelted using hydropower energy, replacing what is often one of the dirtiest manufacturing steps with a low-carbon alternative. The motherboard is a quarter the size of the board in the Latitude 7300 AE, and according to Dell, it could have a 50 percent smaller carbon footprint. A life cycle analysis of the Latitude 7300 AE found that manufacturing accounted for 65 percent of the device's climate impact and printed wire boards were the most energy-intensive components to make. Considering Dell's leading position in the global laptop market, this level of carbon cutting on an individual parts basis could translate to significant reductions across the industry. Another key factor determining how long lived any laptop will be is the availability of spare parts for repair -- most importantly, screens and batteries [...]. [I]ndividuals can already order "tens of thousands" of spare parts from Dell, including replacement screens and batteries, however, these components are often unavailable for purchase online. [I]ncreasing the number of spare parts customers can buy online is "something we are working on right now."

Jonathan Greenberg: Surprising almost no one, the US Federal Trade Commission has moved to block Nvidia's acquisition of Arm. We have written a lot about this deal and Arm in general, and wanted to touch on the topic in light of this news. We will save the background on this deal for that prior piece, but a few things stand out. Arm is seen by regulators as being too important to not be neutral. No other chip company can buy the company, as no one wants to compete with this key supplier of semiconductor intellectual property (IP), and almost every major chip company is now an Arm licensee, one way or another. So what will happen to the company now?

We have to first look at Arm's current owners, Softbank -- the Japanese investment firm. Their original impetus for selling Arm dates back a few years when they were under pressure from some expensive, high-profile deal failures, WeWork being the best known example among several others. At the time, Softbank needed to raise cash or at least convince their own investors that they had the ability to do so. Fast forward to today, and Softbank is in a much better position. They seem to have benefited strongly from the technology stock market bull run over the last two years. They made some big bets on the market and these have paid off, so the company is now in a much better financial position. So one option is for Sotbank to do nothing. Arguably, Arm needs to make some big investments to fund future R&D needs, but from the outside it certainly seems like Arm could raise sufficient funds on its own to do this.

Nonetheless, we have to think that Softbank would still like to exit. They almost made a pile of cash and having it snatched away is the kind of factor that spurs the brain to think of alternatives. The most likely outcome is an IPO of at least a minority stake of Arm. Prior to the Nvidia deal, Softbank seems to have gone far down this path. However, Softbank faced the problem that the public markets would have likely valued Arm less than what Softbank hoped (or possibly even what they paid for it) and far less than what Nvidia offered. The capital markets are in a different place today, and Arm is likely to attract a much higher valuation because semis are hot now in a way they have not been for a long time. One wrinkle for this plan is that an IPO will take some time to arrange. We would guess at least six months, possibly longer. No idea what the markets will look like then, and it leaves Arm in limbo when they should be doing all that R&D investment.

Tyson Foods plans to spend more than $1.3 billion to increase automation in meat plants over the next three years, Chief Executive Donnie King said on Thursday, as a U.S. labor shortage has limited production while demand is booming. Reuters reports: Meat processors have been unable to find enough workers for the past two years due to the tight labor market and health concerns during the COVID-19 pandemic. Tyson expects to boost production and reduce labor costs by expanding automation, with cumulative savings of more than $450 million projected by fiscal year 2024, King said on a webcast for investors.

The company will increasingly use machines, instead of people, to debone chicken, one of its most labor-intensive jobs and a position with high turnover, said David Bray, group president of Tyson's poultry division. A capital investment of $500 million in the area through fiscal year 2024 will generate labor savings equal to more than 2,000 jobs, he said. Profitability in Tyson's chicken unit has declined partly due to the labor shortage and because processing plants are operating below full capacity, Bray said. "We are not servicing our customers to the degree that they expect us to," Bray said.

Toyota will open a multi-billion dollar battery plant with at least 1,750 employees about an hour's drive outside the Triangle, after North Carolina approved an incentive package Monday worth $438.7 million for the company -- one of the largest manufacturing investments in the state's history. From the News & Observer: The Japanese auto maker announced in October it would build a $1.29 billion facility in the United States to manufacture hybrid and electric vehicle batteries -- a key component of the company's plans to make 70% of its cars electric by the end of the decade. The plant known as Toyota Battery Manufacturing, North Carolina will be built in Liberty, a small town in Randolph County that is home to the Greensboro-Randolph Megasite, one of the designated areas in North Carolina the state markets to potential large manufacturers.

Toyota will launch production in 2025 and expand operations by 2031. The site will produce 1.2 million battery packs per year, said Chris Reynolds, chief administrative officer of corporate resources for Toyota North America. The state's Economic Investment Committee approved the state's incentive for Toyota -- referred to internally as Project Darwin -- at a special meeting in Raleigh on Monday. The state's contribution is just one part of an incentive package from numerous entities that could reach $271.4 million. Reynolds did not have a timeline for when construction of the plant would begin but that it would be operational in 2025. Toyota eventually will create 1,750 jobs into 2029, with the jobs paying a minimum average wage of $62,234, according to the state's Commerce Department.

For 32 years a human named Andy Chanley has been a radio announcer (now working afternoon's at Southern California's 88.5 KCSN), Reuters reports. But now.... "I may be a robot, but I still love to rock," says the robot DJ named ANDY, derived from Artificial Neural Disk-JockeY, in Chanley's voice, during a demonstration for Reuters where the voice was hard to distinguish from a human disc jockey.

Our phones, speakers and rice cookers have been talking to us for years, but their voices have been robotic. Seattle-based AI startup WellSaid Labs says it has finessed the technology to create over 50 real human voice avatars like ANDY so far, where the producer just needs to type in text to create the narration....

Martín Ramírez, head of growth at WellSaid, said once the voice avatars are created, WellSaid manages the commercial agreements according to the voice owner's requests. WellSaid voice avatars are doing more than DJ work. They are used in corporate training material or even to read audiobooks, said Ramirez.
The article points out that while (human) announcer Andy Chanley was recording his voice, he discovered he has Stage 2 lymphoma. While he eventually recovered, Chanley liked knowing that there was also another way that the sound of his voice could still be supporting his family — and that his grandchildren could hear the sound of his voice.
