"Around this time last year, millions of Texans were shivering without power during one of the coldest spells to hit the central United States," remembers the Washington Post. "For five days, blackouts prevented people from heating their homes, cooking or even sleeping. More than 200 people died in what is considered the nation's costliest winter storm on record, amounting to $24 billion in damages.

"Twelve months later, the state's electrical grid, while improved, is still vulnerable to weather-induced power outages." "If we got another storm this year, like Uri in 2021, the grid would go down again," said Andrew Dessler, a professor of atmospheric sciences at Texas A&M University. "This is still a huge risk for us."

Now, a recent study shows that electricity blackouts can be avoided across the nation — perhaps even during intense weather events — by switching to 100 percent clean and renewable energy, such as solar, wind and water energy. "Technically and economically, we have 95 percent of the technologies we need to transition everything today," said Mark Jacobson, lead author of the paper and professor of civil and environmental engineering at Stanford University. Wind, water and solar already account for about one fifth of the nation's electricity, although a full transition in many areas is slow.

The study showed a switch to renewables would also lower energy requirements, reduce consumer costs, create millions of new jobs and improve people's health....

The team found the actual energy demand decreased significantly by simply shifting to renewable resources, which are more efficient. For the entire United States, total end-use energy demand decreased by around 57 percent. Per capita household annual energy costs were around 63 percent less than a "business as usual" scenario.... In Texas, a complete green transition would reduce the annual average end-use power demand by 56 percent. It also reduces peak loads, or the highest amount of energy one draws from the grid at a time. Jacobson said many homes would also have their own storage and wouldn't need to rely on the grid as much.

The team also found interconnecting electrical grids from different geographic regions can make the power system more reliable and reduce costs. Larger regions are more likely to have the wind blowing, the sun shining or hydroelectric power running somewhere else, which may be able to help fill any supply gaps. "The intermittency of renewable energy declines as you look at larger and larger areas," said Dessler. "If it's not windy in Texas, it could be windy in Iowa. In that case, they could be overproducing power and they could be shipping some of their extra power to us." The study stated costs per unit energy in Texas are 27 percent lower when interconnected with the Midwest grid than when isolated, as it currently is.
Interestingly, long-duration batteries aren't important for grid stability. the team found, since our current 4-hour batteries can just be connected for longer-term storage. Professor Dessler tells the Post we should think of "renewables" as a system which includes storage technology and easily-dispatchable energy solutions.

And the Post adds that a grid powered by renewables "would also produce cleaner air, which could reduce pollution-related deaths by 53,000 people per year and reduce pollution-related illnesses for millions of people in 2050."

A recent post on the AWS Open Source blog announced that AWS "is investing in the sustainability of Rust, a language we believe should be used to build sustainable and secure solutions."

It was written by the chair of the Rust foundation (and leader of AWS's Rust team) with a Principal Engineer at AWS, and reminds us that Rust "combines the performance and resource efficiency of systems programming languages like C with the memory safety of languages like Java."

But there's another reason they're promoting Rust: Worldwide, data centers consume about 200 terawatt hours per year. That's roughly 1% of all energy consumed on our planet... [C]loud and hyperscale data centers have been implementing huge energy efficiency improvements, and the migration to that cloud infrastructure has been keeping the total energy use of data centers in balance despite massive growth in storage and compute for more than a decade... [I]s the status quo good enough? Is keeping data center energy use to 1% of worldwide energy consumption adequate..? [Will] innovations in energy efficiency continue to keep pace with growth in storage and compute in the future? Given the explosion we know is coming in autonomous drones, delivery robots, and vehicles, and the incredible amount of data consumption, processing, and machine learning training and inference required to support those technologies, it seems unlikely that energy efficiency innovations will be able to keep pace with demand...

[J]ust like security, sustainability is a shared responsibility. AWS customers are responsible for energy efficient choices in storage policies, software design, and compute utilization, while AWS owns efficiencies in hardware, utilization features, and cooling systems.... In the same way that operational excellence, security, and reliability have been principles of traditional software design, sustainability must be a principle in modern software design. That's why AWS announced a sixth pillar for sustainability to the AWS Well-Architected Framework. What that looks like in practice is choices like relaxing service-level agreements for non-critical functions and prioritizing resource use efficiency. We can take advantage of virtualization and allow for longer device upgrade cycles. We can leverage caching and longer times-to-live whenever possible. We can classify our data and implement automated lifecycle policies that delete data as soon as possible. When we choose algorithms for cryptography and compression, we can include efficiency in our decision criteria.

Last, but not least, we can choose to implement our software in energy efficient programming languages.

There was a really interesting study a few years ago that looked at the correlation between energy consumption, performance, and memory use.... What the study did is implement 10 benchmark problems in 27 different programming languages and measure execution time, energy consumption, and peak memory use. C and Rust significantly outperformed other languages in energy efficiency. In fact, they were roughly 50% more efficient than Java and 98% more efficient than Python. It's not a surprise that C and Rust are more efficient than other languages. What is shocking is the magnitude of the difference. Broad adoption of C and Rust could reduce energy consumption of compute by 50% — even with a conservative estimate....

No one developer, service, or corporation can deliver substantial impact on sustainability. Adoption of Rust is like recycling; it only has impact if we all participate. To achieve broad adoption, we are going to have to grow the developer community.
That "interesting study" cited also found that both C and Rust execute faster than other programming languages, the blog post points out, so "when you choose to implement your software in Rust for the sustainability and security benefits, you also get the optimized performance of C."

And the post also notes Linus Torvalds' recent acknowledgement that while he really loves C, it can be like juggling chainsaws, with easily-overlooked and "not always logical" type interactions. (Torvalds then went on to call Rust "the first language I saw which looked like this might actually be a solution.")

AnandTech reports: It's no secret that Intel's enterprise processor platform has been stretched in recent generations. Compared to the competition, Intel is chasing its multi-die strategy while relying on a manufacturing platform that hasn't offered the best in the market. That being said, Intel is quoting more shipments of its latest Xeon products in December than AMD shipped in all of 2021, and the company is launching the next generation Sapphire Rapids Xeon Scalable platform later in 2022. Beyond Sapphire Rapids has been somewhat under the hood, with minor leaks here and there, but today Intel is lifting the lid on that roadmap.

Currently in the market is Intel's Ice Lake 3rd Generation Xeon Scalable platform, built on Intel's 10nm process node with up to 40 Sunny Cove cores. The die is large, around 660 mm2, and in our benchmarks we saw a sizeable generational uplift in performance compared to the 2nd Generation Xeon offering. The response to Ice Lake Xeon has been mixed, given the competition in the market, but Intel has forged ahead by leveraging a more complete platform coupled with FPGAs, memory, storage, networking, and its unique accelerator offerings. Datacenter revenues, depending on the quarter you look at, are either up or down based on how customers are digesting their current processor inventories (as stated by CEO Pat Gelsinger).

No province is too small or remote for Beijing's careful attention. Bloomberg Businessweek: Chinese technology and money have helped build one of Latin America's largest solar energy plants in Jujuy (pronounced hu-HUY), where hundreds of thousands of panels coat the desert like giant dominoes. Chinese security cameras guard government buildings across the provincial capital. Servers hum in a Chinese data storage plant. Beneath the remote, craggy hills and vast salt lakes lie veins of copper, lithium, and zinc, the raw materials of 21st century -- technology -- including Chinese-made electric-car batteries. It's no secret that China has been pouring resources into South America this century, chipping away at the U.S.'s historic dominance and making itself the continent's No. 1 trading partner. But while international focus has turned in recent years to China's ventures in Africa and Asia, an important shift has gone largely unnoticed in the country's approach to South America: going local to expand and strengthen its financial grip.

Instead of focusing on national leaders, China and its companies have built relationships from the ground up. In 2019 alone, at least eight Brazilian governors and four deputy governors traveled to China. In a September 2019 speech, Zou Xiaoli, China's ambassador to Argentina, said his country's infrastructure push was helping weave Latin America into the global marketplace. "China will lend strong support to Argentina's economic and social development," he said. As Argentina's Jujuy province illustrates, no region is too remote for China's scrupulous attention. With perhaps a touch of hyperbole, Gabriel Marquez, chief executive officer of a Jujuy lithium research and development center, describes the effectiveness of the approach: "You have this poor governor from Argentina who has Xi Jinping's phone number."

An anonymous reader quotes a report from Ars Technica: Now that Windows 11's first major post-release update has been issued, Microsoft has started testing a huge collection of new features, UI changes, and redesigned apps in the latest Windows Insider preview for Dev channel users. By and large, the changes are significant and useful -- there's an overhauled Task Manager, folders for pinned apps in the Start menu, the renewed ability to drag items into the Taskbar (as you could in Windows 10), improvements to the Do Not Disturb and Focus modes, new touchscreen gestures, and a long list of other fixes and enhancements.

But tucked away toward the bottom of the changelog is one unwelcome addition: like the Home edition of Windows 11, the Pro version will now require an Internet connection and a Microsoft account during setup. In the current version of Windows 11, you could still create a local user account during setup by not connecting your PC to the Internet -- something that also worked in the Home version of Windows 10 but was removed in 11. That workaround will no longer be available in either edition going forward, barring a change in Microsoft's plans. While most devices do require a sign-in to fully enable app stores, cloud storage, and cross-device sharing and syncing, Windows 11 will soon stand alone as the only major consumer OS that requires account sign-in to enable even basic functionality.

"Akamai, which announced quarterly earnings today, also announced that they plan to acquire longtime Linux VPS host Linode for $900 million," writes Slashdot reader virtig01. From a press release announcing the acquisition: Akamai Technologies, the world's most trusted solution to power and protect digital experiences, today announced it has entered into a definitive agreement to acquire Linode, one of the easiest-to-use and most trusted infrastructure-as-a-service (IaaS) platform providers. [...] Under terms of the agreement, Akamai has agreed to acquire all of the outstanding equity of Linode Limited Liability Company for approximately $900 million, after customary purchase price adjustments. As a result of structuring the transaction as an asset purchase, Akamai expects to achieve cash income tax savings over the next 15 years that have an estimated net present value of approximately $120 million. The transaction is expected to close in the first quarter of 2022 and is subject to customary closing conditions.

Christopher Aker, founder and chief executive officer, Linode, added, "We started Linode 19 years ago to make the power of the cloud easier and more accessible. Along the way, we built a cloud computing platform trusted by developers and businesses around the world. Today, those customers face new challenges as cloud services become all-encompassing, including compute, storage, security and delivery from core to edge. Solving those challenges requires tremendous integration and scale which Akamai and Linode plan to bring together under one roof. This marks an exciting new chapter for Linode and a major step forward for our current and future customers."

An anonymous reader shares a report: In 2014, Google made a remarkable offer: anyone with a Google Apps for Education account in the US got unlimited storage for free. The logic was sound at the time. Three years earlier, the tech giant had launched the Chromebook -- cheap, robust and secure, the web-browser-based kit was a natural fit for education. The cloud was its primary storage, so what could be better than making that bigger than any hard disk in a Mac or Windows PC could ever swallow? The idea was that if you catch users when they are young, they're yours for life. The axiom had already been tested by both Apple and Microsoft, with creative types and workers in jobs with sensible shoes respectively. Google played on its own strengths as the first cloud-native platform for everyone. And lo, it was good. Seven years later, Google has killed the deal.

In place of all you can stash, each institution in the scheme was getting a total pool of 100TB to give to student and teacher alike. If they wanted anything more, the cash register was open. For a small primary school with a couple of hundred pupils, this was perfectly adequate. A large science-heavy university could have a single experiment using that much, however. That announcement was a year ago, and gave existing users 18 months of grace, with new users denied the unlimited package from, well, now. Those with experience of academic deadlines won't be surprised that it has taken this long for lots of people to notice.

What's the lesson after $3.6 billion in stolen bitcoin was seized by America's Justice Department from the couple who laundering it?

Wired argues it all just shows how hard it is to launder cryptocurrency: In the 24 hours since, the cybersecurity world has ruthlessly mocked their operational security screwups: Lichtenstein allegedly stored many of the private keys controlling those funds in a cloud-storage wallet that made them easy to seize, and Morgan flaunted her "self-made" wealth in a series of cringe-inducing rap videos on YouTube and Forbes columns. But those gaffes have obscured the remarkable number of multi-layered technical measures that prosecutors say the couple did use to try to dead-end the trail for anyone following their money.

Even more remarkable, perhaps, is that federal agents, led by IRS Criminal Investigations, managed to defeat those alleged attempts at financial anonymity on the way to recouping $3.6 billion of stolen cryptocurrency. In doing so, they demonstrated just how advanced cryptocurrency tracing has become — potentially even for coins once believed to be practically untraceable.

Ari Redbord, the head of legal and government affairs for TRM Labs, a cryptocurrency tracing and forensics firm...points to the couple's alleged use of "chain-hopping" — transferring funds from one cryptocurrency to another to make them more difficult to follow — including exchanging bitcoins for "privacy coins" like monero and dash, both designed to foil blockchain analysis. Court documents say the couple also allegedly moved their money through the Alphabay dark web market — the biggest of its kind at the time — in an attempt to stymie detectives....Lichtenstein and Morgan appear to have intended to use Alphabay as a "mixer" or "tumbler," a cryptocurrency service that takes in a user's coins and returns different ones to prevent blockchain tracing....

In July 2017, however — six months after the IRS says Lichtenstein moved a portion of the Bitfinex coins into AlphaBay wallets — the FBI, DEA, and Thai police arrested AlphaBay's administrator and seized its server in a data center in Lithuania. That server seizure isn't mentioned in the IRS's statement of facts. But the data on that server likely would have allowed investigators to reconstruct the movement of funds through AlphaBay's wallets and identify Lichtenstein's withdrawals to pick up their trail again, says Tom Robinson, a cofounder of the cryptocurrency tracing firm Elliptic.
The arrests and "largest financial seizure ever show that cryptocurrency is not a safe haven for criminals..." Deputy Attorney General Lisa O. Monaco said in a press release. "Thanks to the meticulous work of law enforcement, the department once again showed how it can and will follow the money, no matter what form it takes."

Or, as Wired puts it, "Even if your rap videos and sloppy cloud storage accounts don't get you caught, your clever laundering tricks may still not save you from the ever-evolving sophistication of law enforcement's crypto-tracers."

A European wide 'supergrid' could cut almost a third from energy costs according to a new study from the UCD Energy Institute. TechXplore reports: Evaluating the capabilities of Europe's energy network, the study, commissioned by SuperNode, found that a pan-European transmission system would reduce energy costs by 32 percent compared to the current approach. The 32 percent cost reduction identified is borne primarily from the expansion of European power flows -- derestricting them to allow the location of renewable generation to be optimized, thereby significantly decreasing the total installed capacity. While this scenario proposes an increase in transmission capacity, the costs were found to be insignificant compared to the cost savings in generation investment over the same period.

This study was an extension of work carried out by SuperNod, based on their Energy Scenario for Europe 2050 modeling -- which aims to predict future energy trends across the continent. Its modelling work, validated and extended by the UCD study and facilitated through ConsultUCD, demonstrates the net benefit of large investment into the development of new transmission assets to ensure more efficient utilization of Europe's renewable resources; highlighting bottlenecks where investment is required, such as higher levels of grid storage. [...] Another key finding from the UCD study is that the existing transmission system is not fit for purpose for Europe's energy future. Without accelerated investment in infrastructure, Europe will face challenges with load shedding, generation curtailment and excessively high emissions. The failure to achieve decarbonisation targets will not just undermine international climate efforts but will adversely affect Europe's economies and ability to compete on a global scale, the report notes. The study has been broken into two parts (PDFs).

Western Digital said on Wednesday certain materials at two of its manufacturing units in Japan, operated by joint-venture partner Kioxia Holdings, were contaminated and will result in reduced availability of flash storage devices. From a report: According to the company's current assessment, there would be a shortage of at least 6.5 exabytes in flash storage availability. One exabyte equals one billion gigabytes. Western Digital is working closely with Kioxia to implement necessary measures that will restore the facilities to normal operational status as quickly as possible.

An anonymous reader quotes a report from Ars Technica: Recently, two computer scientists had an idea: if computers use energy to perform calculations, could stored data be a form of stored energy? Why not use computing as a way to store energy? What if information could be a battery, man? As it turns out, the idea isn't as far-fetched as it may sound. The "information battery" concept, fleshed out in a recent paper (PDF), would perform certain computations in advance when power is cheap -- like when the sun is shining or the wind is blowing -- and cache the results for later. The process could help data centers replace up to 30 percent of their energy use with surplus renewable power.

The beauty of the system is that it requires no specialized hardware and imposes very little overhead. "Information Batteries are designed to work with existing data centers," write authors Jennifer Switzer, a doctoral student at UC San Diego, and Barath Raghavan, an assistant professor at the University of Southern California. "Some very limited processing power is reserved for the IB [information battery] manager, which manages the scheduling of both real-time computational tasks and precomputation. A cluster of machines or VMs is designated for precomputation. The IB cache, which stores the results of these precomputations, is kept local for quick retrieval. No additional infrastructure is needed."

In the model Switzer and Raghavan created to test the concept, the IB manager queried grid operators every five minutes -- the smallest time interval the operators offered -- to check the price of power to inform its predictions. When prices dipped below a set threshold, the manager green-lit a batch of computations and cached them for later. The system was pretty effective at reducing the need for expensive "grid power," as the authors call it, even when the pre-computation engine did a relatively poor job of predicting which tasks would be needed in the near future. At just 30 percent accuracy, the manager could begin to make the most of the so-called "opportunity power" that is created when there is excess wind or solar power. In a typical large data center, workloads can be predicted around 90 minutes in advance with about 90 percent accuracy, the authors write. With a more conservative prediction window of 60 minutes, "such a data center could store 150 MWh, significantly more than most grid-scale battery-based storage projects," they say. An equivalent grid-scale battery would cost around $50 million, they note.

A California newspaper covers "pleas" to the state's governor to delay the closure of a nuclear power plant: On Thursday, Dr. Steven Chu, former U.S. Secretary of Energy under the Obama administration and a Nobel laureate, and more than 79 scientists, academics and entrepreneurs sent a letter to [California governor] Newsom urging him to find a way to keep the plant open because of the necessary carbon-free, clean electricity it provides to the state's electricity grid. Diablo Canyon currently provides about 18,000 gigawatt-hours of clean electricity annually, comprising of about 10% of the state's electricity portfolio....

The letter was sent by the nonprofit foundation Save Clean Energy, which was organized primarily to protest the closure of the nuclear power plant.... The letter details how Diablo Canyon is critical to the state's clean energy goals, which the state is legally mandated to meet, and how it seems unlikely the state will be able to meet those goals with the plant's current scheduled decommissioning beginning in November 2024, when the first of its two Nuclear Regulatory Licenses expires.... The movement to keep Diablo Canyon nuclear power plant open has recently gained new traction after a Stanford and Massachusetts Institute of Technology report released in November claimed operating the plant for 10 years beyond its expected closure would significantly help the state meet its clean energy goals.

In a statement sent to The Tribune in December, a spokesperson for Newsom indicated the governor has no intention of delaying the closure of Diablo Canyon. "California has the technology to achieve California's clean energy goals without compromising our energy needs. The pathway is through diverse renewable energy sources, expanded energy storage and grid climate resiliency," Newsom spokesperson Erin Mellon wrote in an email to The Tribune. "Our retail energy providers are already in the process of procuring new energy projects to replace the energy produced by Diablo Canyon."

An anonymous reader quotes a report from Ars Technica: Most companies still haven't shifted their entire NVMe SSD lineups to use PCI Express 4.0, but PCIe 5.0 SSDs for PCs are already on the horizon. Storage company Silicon Motion said in a recent earnings call that it expects its PCIe 5.0-capable SSD controllers for consumer SSDs will be available sometime in 2024, opening the door to a wide variety of high-performance drives from different manufacturers. SSD manufacturer ADATA teased some PCIe 5.0 SSDs at CES last month (albeit without an expected release date), boasting of read speeds up to 14GB/s and write speeds of up to 12GB/s using a Silicon Motion SM2508 controller. Current high-end PCIe 4.0 SSDs like Samsung's 980 Pro top out at roughly half those speeds.

Other reports have suggested that these PCIe 5.0 consumer SSDs are coming later in 2022, but according to the call transcript, that only applies to the latest version of Silicon Motion's PCIe 5.0 controller for enterprise SSDs -- the products that end up in servers and data centers, not what typically ends up in the PC on your desk or lap. Early PCIe 4.0 SSDs for consumer PCs were also demonstrated at CES a couple of years before they became products that you could actually buy. For 2022 and 2023, Silicon Motion will continue to focus on those PCIe 4.0 SSDs. Budget SSDs like Western Digital's WD Black SN770 SE are only beginning to transition to PCIe 4.0, and according to reviews like this one from Tom's Hardware, their controllers and flash memory aren't yet fast enough to benefit much from the extra bandwidth. Silicon Motion also says that PCIe 4.0 SSDs have only become common in pre-built PCs within the last year because of "extensive verification and testing" requirements.

Google today announced a new version of Workspace, the company's productivity service that you probably still refer to as G Suite. With the new -- and free -- Google Workspace Essentials plan, Google wants to bring more business users onto the platform by offering them the basic Workspace productivity tools -- with the exception of Gmail. From a report: Until now, in order to use Workspace with a non-Google email address, you had to sign up for the $6/month/user Business Starter account after a 14-day trial. That paid plan is not going away, but all you now need to do is sign up with your work email and you're good to go. No credit card needed. The new free plan is essentially the existing entry-level Business Starter plan, but with a reduced storage quota of 15 GB (down from 30). Otherwise, though, you can use Google Meet with up to 100 users for up to 60 minutes in each call, get access to Spaces for work collaboration and Chat for gossiping about their co-workers. All of the standard tools like Sheets, Slides and Docs are also included, of course. Since you already have an email address from work, though, there's no Gmail included in this edition, which makes sense, given that it would be tough to send out emails with your work address from there, leading to all kinds of confusion.

joshuark writes: Microsoft has filed an amicus brief supporting Epic Games in its appeal against Apple, and argues that, "the potential antitrust issues stretch far beyond gaming." As Epic Games continues to file its appeal against the 2021 ruling that chiefly favored Apple, interested parties have been contributing supporting filings to the court. Notably, those have included US attorneys general, but now Microsoft has also joined in on the side of Epic Games. Microsoft's amicus filing included below, sets out what it describes as its own "unique -- and balanced -- perspective to the legal, economic, and technological issues this case implicates." As a firm which, like Apple, sells both hardware and software, Microsoft says it "has an interest" in supporting antitrust law. Describing what it calls Apple's "extraordinary gatekeeper power," Microsoft joins Epic Games in criticizing alleged errors in the original trial judge's conclusions. "Online commerce and interpersonal connection funnels significantly, and sometimes predominantly, through iOS devices," says Microsoft. "Few companies, perhaps none since AT&T... at the height of its telephone monopoly, have controlled the pipe through which such an enormous range of economic activity flows." To support its claim that the Epic Games vs Apple ruling has "potential antitrust issues [that] stretch far beyond gaming," Microsoft describes what else it sees as this "enormous range of economic activity." "Beyond app distribution and in-app payment solutions - the adjacent markets directly at issue in this case," says Microsoft's filing, "Apple offers mobile payments, music, movies and television, advertising, games, health tracking, web browsing, messaging, video chat, news, cloud storage, e-books, smart-home devices, wearables, and more besides."

Backblaze, a cloud storage service that's been running hundreds of thousands of storage drives to keep an eye on reliability, has issued its latest report. ZDNet summarizes the major findings: Over 2021, Backblaze added 40,460 hard drives to its pool of drives, making a total of 206,928 drives in total. Of thee, 3,760 are boot drives and 203,168 are data drives. There's a lot of information in the report to look at, but there are two standout parts from the report:

- The oldest drive is the most reliable: 6TB Seagate drives (model: ST6000DX000) have an average age of 80.4 months (almost seven years) yet incredibly these also have the lowest annualized failure rate (AFR) of 0.11 percent.
- Newer drives are also doing really well: 16TB WDC drives (model: WUH721816ALE6L0) and 16TB Toshiba drives (model: MG08ACA16TE) were both added in 2021, and have an AFR of 0.14 and 0.91 percent, respectively.

Backblaze had also been experiencing problems with the 14TB Seagate drives (model: ST14000NM0138) in its Dell storage servers. It seems that following a firmware update the reliability of these drives has improved dramatically. Further reading: Seagate HDDs Top and Bottom Backblaze's 2021 Failure Rates Data (Tom's Hardware)

A venture capital-backed battle is raging in New York City in the burgeoning field of instant delivery. From a report: At least six startups, including Gorillas, Jokr SARL, Getir Perakende Lojistik and Buyk, are vying to win the chance to ferry groceries to customers within 10 to 20 minutes of their order placement on an app. Prices are similar to grocery stores, discounts are plentiful, and many services don't have a fee or minimum order, allowing consumers to request a single pint of Ben & Jerry's delivered to their doorstep. Food-delivery app DoorDash, based in San Francisco, also recently entered the fray in New York City.

While these consumer-friendly offerings have brought surging sales, losses are heavy given the high cost of prolific advertising and paying couriers to hand-deliver potato chips, soap and eggs in a short time frame, industry investors and executives said. Some of the companies are averaging a loss of over $20 per order when factoring in costs like advertising, those people said. "The economics are brutal," said Damir Becirovic, a principal at venture-capital firm Index Ventures, which hasn't invested in any of the startups. He added that if any of the companies can build a giant business with efficiencies from scale, that picture could change, but the short-term challenges seem daunting. Take for example Fridge No More, a New York-based company that launched in 2020. As of September, its average order value was $33, according to a 2021 investor presentation viewed by The Wall Street Journal. After paying for the products, the people packaging them, delivery riders, waste and other expenses related to storage, it lost $3.30 on every order. That doesn't include marketing costs. Fridge No More spent $70 on advertising to win the average customer, an investment that resulted in a $78 loss for every customer that stayed in the 10 months through September, according to the presentation.

If you're using either Dropbox or Microsoft OneDrive to sync files on a Mac, you'll want to pay attention to the release notes for today's macOS 12.3 beta: the update is deprecating a kernel extension used by both apps to download files on demand. Ars Technica reports: The extension means that files are available when you need them but don't take up space on your disk when you don't. Apple says that "both service providers have replacements for this functionality currently in beta." Both Microsoft and Dropbox started alerting users to this change before the macOS beta even dropped. Dropbox's page is relatively sparse. The page notifies users that Dropbox's online-only file functionality will break in macOS 12.3 and that a beta version of the Dropbox client with a fix will be released in March.

Microsoft's documentation for OneDrive's Files On-Demand feature is more detailed. It explains that Microsoft will be using Apple's File Provider extensions for future OneDrive versions, that the new Files On-Demand feature will be on by default, and that Files On-Demand will be supported in macOS 12.1 and later.

In addition to integrating better with the Finder (also explained by Microsoft here), using modern Apple extensions should reduce the number of obnoxious permission requests each app generates. The extensions should also reduce the likelihood that a buggy or compromised kernel extension can expose your data or damage your system. But the move will also make those apps a bit less flexible -- Microsoft says that the new version of Files On-Demand can't be disabled. That might be confusing if you expect to have a full copy of your data saved to your disk even when you're offline.

Sweden's government gave the go-ahead on Thursday for the building of a storage facility to keep the country's spent nuclear fuel safe for the next 100,000 years. From a report: What to do with nuclear waste has been a major headache since the world's first nuclear plants came on line in the 1950s and 1960s. The International Atomic Energy Agency estimates that there is around 370,000 tonnes of highly radioactive, spent nuclear fuel in temporary storage around the globe. "Our generation must take responsibility for nuclear waste. This is the result of 40 years of research and it will be safe for 100,000 years," Environment Minister Annika Strandhall told reporters at a news conference. "The solution for the final storage of spent nuclear fuel - through that, we ensure that we can use our current nuclear power as a part of the transition to becoming the world's first fossil-free, developed nation."

An anonymous reader quotes a report from The Wall Street Journal: Meta said Monday that its research team built a new artificial intelligence supercomputer that the company maintains will soon be the fastest in the world. The supercomputer, the AI Research SuperCluster, was the result of nearly two years of work, often conducted remotely during the height of the pandemic, and led by the Facebook parent's AI and infrastructure teams. Several hundred people, including researchers from partners Nvidia, Penguin Computing and Pure Storage, were involved in the project, the company said.

Meta, which announced the news in a blog post Monday, said its research team currently is using the supercomputer to train AI models in natural-language processing and computer vision for research. The aim is to boost capabilities to one day train models with more than a trillion parameters on data sets as large as an exabyte, which is roughly equivalent to 36,000 years of high-quality video. "The experiences we're building for the metaverse require enormous compute powerand RSC will enable new AI models that can learn from trillions of examples, understand hundreds of languages, and more," Meta CEO Mark Zuckerberg said in a statement provided to The Wall Street Journal. Meta's AI supercomputer houses 6,080 Nvidia graphics-processing units, putting it fifth among the fastest supercomputers in the world, according to Meta.

By mid-summer, when the AI Research SuperCluster is fully built, it will house some 16,000 GPUs, becoming the fastest AI supercomputer in the world, Meta said. The company declined to comment on the location of the facility or the cost. [...] Eventually the supercomputer will help Meta's researchers build AI models that can work across hundreds of languages, analyze text, images and video together and develop augmented reality tools, the company said. The technology also will help Meta more easily identify harmful content and will aim to help Meta researchers develop artificial-intelligence models that think like the human brain and support rich, multidimensional experiences in the metaverse. "In the metaverse, it's one hundred percent of the time, a 3-D multi-sensorial experience, and you need to create artificial-intelligence agents in that environment that are relevant to you," said Jerome Pesenti, vice president of AI at Meta.
