Apple's AI Plans Include 'Black Box' For Cloud Data (appleinsider.com) 9

How will Apple protect user data while their requests are being processed by AI in applications like Siri?

Long-time Slashdot reader AmiMoJo shared this report from Apple Insider: According to sources of The Information [four different former Apple employees who worked on the project], Apple intends to process data from AI applications inside a virtual black box.

The concept, known as "Apple Chips in Data Centers" internally, would involve only Apple's hardware being used to perform AI processing in the cloud. The idea is that it will control both the hardware and software on its servers, enabling it to design more secure systems. While on-device AI processing is highly private, the initiative could make cloud processing for Apple customers to be similarly secure... By taking control over how data is processed in the cloud, it would make it easier for Apple to implement processes to make a breach much harder to actually happen.

Furthermore, the black box approach would also prevent Apple itself from being able to see the data. As a byproduct, this means it would also be difficult for Apple to hand over any personal data from government or law enforcement data requests.

Processed data from the servers would be stored in Apple's "Secure Enclave" (where the iPhone stores biometric data, encryption keys and passwords), according to the article.

"Doing so means the data can't be seen by other elements of the system, nor Apple itself."

Google Cloud Explains How It Accidentally Deleted a Customer Account (arstechnica.com) 72

Google Cloud faced a major setback earlier this month when it accidentally deleted the account of UniSuper, an Australian pension fund managing $135 billion in assets, causing a two-week outage for its 647,000 members. Google Cloud has since completed an internal review of the incident and published a blog post detailing the findings. ArsTechnica: Google has a "TL;DR" at the top of the post, and it sounds like a Google employee got an input wrong.

"During the initial deployment of a Google Cloud VMware Engine (GCVE) Private Cloud for the customer using an internal tool, there was an inadvertent misconfiguration of the GCVE service by Google operators due to leaving a parameter blank. This had the unintended and then unknown consequence of defaulting the customer's GCVE Private Cloud to a fixed term, with automatic deletion at the end of that period. The incident trigger and the downstream system behavior have both been corrected to ensure that this cannot happen again."

Amazon Cloud Traffic Is Suffocating Fedora's Mirrors (phoronix.com) 53

Michael Larabel reports via Phoronix: A massive uptick in traffic to Fedora's package mirrors is causing problems for the Linux distribution. Some five million additional systems have started putting additional strain on Fedora's mirror resources since March and appear to be coming from Amazon's cloud. Stephen Smoogen of Red Hat wrote a blog post today around 5+ million more EPEL-7 systems beginning in March. Fedora hosts the packaging mirrors for Extra Packages For Enterprise Linux (EPEL) to augment the package selection available on RHEL, CentOS, Amazon Linux, etc.

The past three months now there has been a 5+ million surge in Fedora/EPEL traffic and it's placed a strain on the systems. It's about doubling the number of unique IPs connecting to the mirror system. The massive uptick in Fedora/EPEL activity puts additional pressure on Fedora web proxies for mirror data and then the mirrors themselves that tend to be volunteer run. Much of this new traffic is coming from the Amazon/AWS cloud.

Earthcare Cloud Mission Launches To Resolve Climate Unknowns (bbc.com) 25

An anonymous reader quotes a report from the BBC: A sophisticated joint European-Japanese satellite has launched to measure how clouds influence the climate. Some low-level clouds are known to cool the planet, others at high altitude will act as a blanket. The Earthcare mission will use a laser and a radar to probe the atmosphere to see precisely where the balance lies. It's one of the great uncertainties in the computer models used to forecast how the climate will respond to increasing levels of greenhouse gases. "Many of our models suggest cloud cover will go down in the future and that means that clouds will reflect less sunlight back to space, more will be absorbed at the surface and that will act as an amplifier to the warming we would get from carbon dioxide," Dr Robin Hogan, from the European Centre for Medium-Range Weather Forecasts, told BBC News.

The 2.3-tonne satellite was sent up from California on a SpaceX rocket. The project is led by the European Space Agency (ESA), which has described it as the organization's most complex Earth observation venture to date. Certainly, the technical challenge in getting the instruments to work as intended has been immense. It's taken fully 20 years to go from mission approval to launch. Earthcare will circle the Earth at a height of about 400km (250 miles). It's actually got four instruments in total that will work in unison to get at the information sought by climate scientists.

The simplest is an imager -- a camera that will take pictures of the scene passing below the spacecraft to give context to the measurements made by the other three instruments. Earthcare's European ultraviolet laser will see the thin, high clouds and the tops of clouds lower down. It will also detect the small particles and droplets (aerosols) in the atmosphere that influence the formation and behavior of clouds. The Japanese radar will look into the clouds, to determine how much water they are carrying and how that's precipitating as rain, hail and snow. And a radiometer will sense how much of the energy falling on to Earth from the Sun is being reflected or radiated back into space.

Rivers of Lava on Venus Reveal a More Volcanically Active Planet (nytimes.com) 24

Witnessing the blood-red fires of a volcanic eruption on Earth is memorable. But to see molten rock bleed out of a volcano on a different planet would be extraordinary. That is close to what scientists have spotted on Venus: two vast, sinuous lava flows oozing from two different corners of Earth's planetary neighbor. From a report: "After you see something like this, the first reaction is 'wow,'" said Davide Sulcanese, a doctoral student at the Universita d'Annunzio in Pescara, Italy, and an author of a study reporting the discovery in the journal Nature Astronomy, published on Monday. Earth and Venus were forged at the same time. Both are made of the same primeval matter, and both are the same age and size. So why is Earth a paradise overflowing with water and life, while Venus is a scorched hellscape with acidic skies?

Volcanic eruptions tinker with planetary atmospheres. One theory holds that, eons ago, several apocalyptic eruptions set off a runaway greenhouse effect on Venus, turning it from a temperate, waterlogged world into an arid desert of burned glass. To better understand its volcanism, scientists hoped to catch a Venusian eruption in the act. But although the planet is known to be smothered in volcanoes, an opaque atmosphere has prevented anyone from seeing an eruption the way spacecraft have spotted them on Io, the hypervolcanic moon of Jupiter. In the 1990s, NASA's spacecraft Magellan used cloud-penetrating radar to survey most of the planet. But back then, the relatively low-resolution images made spotting fresh molten rock a troublesome task.

How A US Hospital is Using AI to Analyze X-Rays - With Help From Red Hat (redhat.com) 19

This week Red Hat announced one of America's leading pediatric hospitals is using AI to analyze X-rays, "to improve image quality and the speed and accuracy of image interpretation."

Red Hat's CTO said the move exemplifies "the positive impact AI can have in the healthcare field". Before Boston Children's Hospital began piloting AI in radiology, quantitative measurements had to be done manually, which was a time-consuming task. Other, more complex image analyses were performed completely offline and outside of the clinical workflow. In a field where time is of the essence, the hospital is piloting Red Hat OpenShift via the ChRIS Research Integration Service, a web-based medical image platform. The AI application running in ChRIS on the Red Hat OpenShift foundation has the potential to automatically examine x-rays, identify the most valuable diagnostic images among the thousands taken and flag any discrepancies for the radiologist. This decreases the interpretation time for radiologists.
But it also seems to be a big win for openness: Innovation developed internally is immediately transferable to public research clouds such as the Massachusetts Open Cloud, where large-scale data sharing and additional innovation can be fostered. Boston Children's Hospital aims to extend the reach of advanced healthcare solutions globally through this approach, amplifying their impact on patient well-being worldwide.
"Red Hat believes open unlocks the world's potential," the announcement concludes, "including the potential to share knowledge and build upon each other's discoveries. Additionally, Red Hat believes innovation — including AI — should be available everywhere, making any application, anywhere a reality.

"With open source, enabling AI-fueled innovation across hybrid IT environments that can lead to faster clinical breakthroughs and better patient outcomes is a reality."

Satya Nadella Says Microsoft's AI-Focused Copilot+ Laptops Will Outperform Apple's MacBooks (msn.com) 83

"Apple's done a fantastic job of really innovating on the Mac," Microsoft CEO Satya Nadella told the Wall Street Journal in a video interview this week.

. Then he said "We are gonna outperform them" with the upcoming Copilot+ laptops from Acer, ASUS, Dell, HP, Lenovo and Samsung that have been completely reengineered for AI — and begin shipping in less than four weeks. Satya Nadella: Qualcomm's got a new [ARM Snapdragon X] processor, which we've optimized Windows for. The battery lab, I've been using it now — I mean, it's 22 hours of continuous video playback... [Apple also uses ARM chips in its MacBooks]. We finally feel we have a very competitive product between Surface Pro and the Surface laptops. We have essentially the best specs when it comes to ARM-based silicon and performance or the NPU performance.

WSJ: Microsoft says the Surfaces are 58% faster than the MacBook Air with M3, and has 20% longer battery life.

The video includes a demonstration of local live translation powered by "small language models" stored on the device. ("It can translate live video calls or in-person conversations from 44 different languages into English. And it's fast.")

And in an accompanying article, the Journal's reporter also tested out the AI-powered image generator coming to Microsoft Paint.

As a longtime MS Paint stick-figure and box-house artist, I was delighted by this new tool. I typed in a prompt: "A Windows XP wallpaper with a mountain and sky." Then, as I started drawing, an AI image appeared in a new canvas alongside mine. When I changed a color in my sketch, it changed a color in the generated image. Microsoft says it still sends the prompt to the cloud to ensure content safety.
Privacy was also touched on. Discussing the AI-powered "Recall" search functionality, the Journal's reporter notes that users can stop it from taking screenshots of certain web sites or apps, or turn it off entirely... But they point out "There could be this reaction from some people that this is pretty creepy. Microsoft is taking screenshots of everything I do."

Nadella reminds them that "it's all being done locally, right...? That's the promise... That's one of the reasons why Recall works as a magical thing: because I can trust it, that it is on my computer."

Copilot will be powered by OpenAI's new GPT-4o, the Journal notes — before showing Satya Nadella saying "It's kind of like a new browser effectively." Satya Nadella: So, it's right there. It sees the screen, it sees the world, it hears you. And so, it's kind of like that personal agent that's always there that you want to talk to. You can interrupt it. It can interrupt you.
Nadella says though the laptop is optimized for Copilot, that's just the beginning, and "I fully expect Copilot to be everywhere" — along with its innovatively individualized "personal agent" interface. "It's gonna be ambient.... It'll go on the phone, right? I'll use it on WhatsApp. I'll use it on any other messaging platform. It'll be on speakers everywhere." Nadella says combining GPT-40 with Copilot's interface is "the type of magic that we wanna bring — first to Windows and everywhere else... The future I see is a computer that understands me versus a computer that I have to understand.

The interview ends when the reporter holds up the result — their own homegrown rendition of Windows XP's default background image "Bliss."

Microsoft Edge Will Begin Blocking Screenshots On the Job (pcworld.com) 99

Microsoft is adding screenshot prevention controls in Edge to block you from taking screenshots at work. "It's all designed to prevent you from sharing screenshots with competitors, relatives, and journalists using Microsoft Edge for Business," reports PCWorld. From the report: Specifically, IT managers at corporations will be able to tag web pages as protected, as defined in various Microsoft policy engines in Microsoft 365, Microsoft Defender for Cloud Apps, Microsoft Intune Mobile Application Management and Microsoft Purview, Microsoft said. The screenshot prevention feature will be available to customers in the "coming months," Microsoft said. It's also unclear whether third-party tools will be somehow blocked from taking screenshots or recording video, too.

Microsoft will also roll out a way to force Edge for Business users to automatically update their browsers. The feature will enter a preview phase over the next few weeks, Microsoft said. "The Edge management service will enable IT admins to see which devices have Edge instances that are out of date and at risk," Microsoft said. "It will also provide mitigating controls, such as forcing a browser restart to install updates, enabling automatic browser updates or enabling enhanced security mode for added protections."

DOJ Makes Its First Known Arrest For AI-Generated CSAM (engadget.com) 98

In what's believed to be the first case of its kind, the U.S. Department of Justice arrested a Wisconsin man last week for generating and distributing AI-generated child sexual abuse material (CSAM). Even if no children were used to create the material, the DOJ "looks to establish a judicial precedent that exploitative materials are still illegal," reports Engadget. From the report: The DOJ says 42-year-old software engineer Steven Anderegg of Holmen, WI, used a fork of the open-source AI image generator Stable Diffusion to make the images, which he then used to try to lure an underage boy into sexual situations. The latter will likely play a central role in the eventual trial for the four counts of "producing, distributing, and possessing obscene visual depictions of minors engaged in sexually explicit conduct and transferring obscene material to a minor under the age of 16." The government says Anderegg's images showed "nude or partially clothed minors lasciviously displaying or touching their genitals or engaging in sexual intercourse with men." The DOJ claims he used specific prompts, including negative prompts (extra guidance for the AI model, telling it what not to produce) to spur the generator into making the CSAM.

Cloud-based image generators like Midjourney and DALL-E 3 have safeguards against this type of activity, but Ars Technica reports that Anderegg allegedly used Stable Diffusion 1.5, a variant with fewer boundaries. Stability AI told the publication that fork was produced by Runway ML. According to the DOJ, Anderegg communicated online with the 15-year-old boy, describing how he used the AI model to create the images. The agency says the accused sent the teen direct messages on Instagram, including several AI images of "minors lasciviously displaying their genitals." To its credit, Instagram reported the images to the National Center for Missing and Exploited Children (NCMEC), which alerted law enforcement. Anderegg could face five to 70 years in prison if convicted on all four counts. He's currently in federal custody before a hearing scheduled for May 22.

Linux Foundation Announces Launch of 'High Performance Software Foundation' (linuxfoundation.org) 4

This week the nonprofit Linux Foundation announced the launch of the High Performance Software Foundation, which "aims to build, promote, and advance a portable core software stack for high performance computing" (or HPC) by "increasing adoption, lowering barriers to contribution, and supporting development efforts."

It promises initiatives focused on "continuously built, turnkey software stacks," as well as other initiatives including architecture support and performance regression testing. Its first open source technical projects are:

- Spack: the HPC package manager.

- Kokkos: a performance-portable programming model for writing modern C++ applications in a hardware-agnostic way.

- Viskores (formerly VTK-m): a toolkit of scientific visualization algorithms for accelerator architectures.

- HPCToolkit: performance measurement and analysis tools for computers ranging from desktop systems to GPU-accelerated supercomputers.

- Apptainer: Formerly known as Singularity, Apptainer is a Linux Foundation project providing a high performance, full featured HPC and computing optimized container subsystem.

- E4S: a curated, hardened distribution of scientific software packages.

As use of HPC becomes ubiquitous in scientific computing and digital engineering, and AI use cases multiply, more and more data centers deploy GPUs and other compute accelerators. The High Performance Software Foundation will provide a neutral space for pivotal projects in the high performance computing ecosystem, enabling industry, academia, and government entities to collaborate on the scientific software.

The High Performance Software Foundation benefits from strong support across the HPC landscape, including Premier Members Amazon Web Services (AWS), Hewlett Packard Enterprise, Lawrence Livermore National Laboratory, and Sandia National Laboratories; General Members AMD, Argonne National Laboratory, Intel, Kitware, Los Alamos National Laboratory, NVIDIA, and Oak Ridge National Laboratory; and Associate Members University of Maryland, University of Oregon, and Centre for Development of Advanced Computing.

In a statement, an AMD vice president said that by joining "we are using our collective hardware and software expertise to help develop a portable, open-source software stack for high-performance computing across industry, academia, and government." And an AWS executive said the high-performance computing community "has a long history of innovation being driven by open source projects. AWS is thrilled to join the High Performance Software Foundation to build on this work. In particular, AWS has been deeply involved in contributing upstream to Spack, and we're looking forward to working with the HPSF to sustain and accelerate the growth of key HPC projects so everyone can benefit."

The new foundation will "set up a technical advisory committee to manage working groups tackling a variety of HPC topics," according to the announcement, following a governance model based on the Cloud Native Computing Foundation.

How an 'Unprecedented' Google Cloud Event Wiped Out a Major Customer's Account (arstechnica.com) 50

Ars Technica looks at what happened after Google's answer to Amazon's cloud service "accidentally deleted a giant customer account for no reason..."

"[A]ccording to UniSuper's incident log, downtime started May 2, and a full restoration of services didn't happen until May 15." UniSuper, an Australian pension fund that manages $135 billion worth of funds and has 647,000 members, had its entire account wiped out at Google Cloud, including all its backups that were stored on the service... UniSuper's website is now full of must-read admin nightmare fuel about how this all happened. First is a wild page posted on May 8 titled "A joint statement from UniSuper CEO Peter Chun, and Google Cloud CEO, Thomas Kurian...." Google Cloud is supposed to have safeguards that don't allow account deletion, but none of them worked apparently, and the only option was a restore from a separate cloud provider (shoutout to the hero at UniSuper who chose a multi-cloud solution)... The many stakeholders in the service meant service restoration wasn't just about restoring backups but also processing all the requests and payments that still needed to happen during the two weeks of downtime.

The second must-read document in this whole saga is the outage update page, which contains 12 statements as the cloud devs worked through this catastrophe. The first update is May 2 with the ominous statement, "You may be aware of a service disruption affecting UniSuper's systems...." Seven days after the outage, on May 9, we saw the first signs of life again for UniSuper. Logins started working for "online UniSuper accounts" (I think that only means the website), but the outage page noted that "account balances shown may not reflect transactions which have not yet been processed due to the outage...." May 13 is the first mention of the mobile app beginning to work again. This update noted that balances still weren't up to date and that "We are processing transactions as quickly as we can." The last update, on May 15, states, "UniSuper can confirm that all member-facing services have been fully restored, with our retirement calculators now available again."

The joint statement and the outage updates are still not a technical post-mortem of what happened, and it's unclear if we'll get one. Google PR confirmed in multiple places it signed off on the statement, but a great breakdown from software developer Daniel Compton points out that the statement is not just vague, it's also full of terminology that doesn't align with Google Cloud products. The imprecise language makes it seem like the statement was written entirely by UniSuper.

Companies Are So Desperate For Data Centers They're Leasing Them Before They're Even Built (sherwood.news) 23

Data center construction levels are at an all-time high. And more than ever, companies that need them have already called dibs. From a report: In the first quarter of 2024, what amounts to about half of the existing supply of data center megawattage in the US is under construction, according to real estate services firm CBRE. And 84% of that is already leased. Typically that rate had been about 50% the last few years -- already notably higher than other real estate classes. "I'm astonished and impressed by the demand for facilities yet to be fully constructed," CBRE Data Center Research Director Gordon Dolven told Sherwood.

That advanced interest means that despite the huge amount of construction, there's still going to be a shortage of data centers to meet demand. In other words, data center vacancy rates are staying low and rents high. Nationwide the vacancy rates are near record lows of 3.7% and average asking rent for data centers was up 19% year over year, according to CBRE. It was up 42% in Northern Virginia, where many data centers are located. These sorts of price jumps are "unprecedented" compared with other types of real estate. For comparison, rents for industrial and logistics real estate, another hot asset class used in e-commerce, is expected to go up 8% this year.

Hugging Face Is Sharing $10 Million Worth of Compute To Help Beat the Big AI Companies (theverge.com) 10

Kylie Robison reports via The Verge: Hugging Face, one of the biggest names in machine learning, is committing $10 million in free shared GPUs to help developers create new AI technologies. The goal is to help small developers, academics, and startups counter the centralization of AI advancements. [...] Delangue is concerned about AI startups' ability to compete with the tech giants. Most significant advancements in artificial intelligence -- like GPT-4, the algorithms behind Google Search, and Tesla's Full Self-Driving system -- remain hidden within the confines of major tech companies. Not only are these corporations financially incentivized to keep their models proprietary, but with billions of dollars at their disposal for computational resources, they can compound those gains and race ahead of competitors, making it impossible for startups to keep up. Hugging Face aims to make state-of-the-art AI technologies accessible to everyone, not just the tech giants. [...]

Access to compute poses a significant challenge to constructing large language models, often favoring companies like OpenAI and Anthropic, which secure deals with cloud providers for substantial computing resources. Hugging Face aims to level the playing field by donating these shared GPUs to the community through a new program called ZeroGPU. The shared GPUs are accessible to multiple users or applications concurrently, eliminating the need for each user or application to have a dedicated GPU. ZeroGPU will be available via Hugging Face's Spaces, a hosting platform for publishing apps, which has over 300,000 AI demos created so far on CPU or paid GPU, according to the company.

Access to the shared GPUs is determined by usage, so if a portion of the GPU capacity is not actively utilized, that capacity becomes available for use by someone else. This makes them cost-effective, energy-efficient, and ideal for community-wide utilization. ZeroGPU uses Nvidia A100 GPU devices to power this operation -- which offer about half the computation speed of the popular and more expensive H100s. "It's very difficult to get enough GPUs from the main cloud providers, and the way to get them -- which is creating a high barrier to entry -- is to commit on very big numbers for long periods of times," Delangue said. Typically, a company would commit to a cloud provider like Amazon Web Services for one or more years to secure GPU resources. This arrangement disadvantages small companies, indie developers, and academics who build on a small scale and can't predict if their projects will gain traction. Regardless of usage, they still have to pay for the GPUs. "It's also a prediction nightmare to know how many GPUs and what kind of budget you need," Delangue said.

Palo Alto Networks Is Buying Security Assets From IBM (cnbc.com) 5

Palo Alto Networks is acquiring IBM's QRadar cloud software and migrating customers to its Cortex Xsiam platform as part of a broader partnership aimed at expanding its consulting capabilities and customer base. The sum of the deal was not disclosed. CNBC reports: The move normally takes one to three months, Nikesh Arora, Palo Alto's CEO, told CNBC. Also, IBM will train more than 1,000 of its consulting employees on Palo Alto's products. [...] For IBM, a more robust lineup of contemporary security tools for consulting might help the company deliver on its stated goal of revenue growth in the mid-single digits for 2024. In the first quarter, revenue increased 3%, with a 2% bump in the consulting segment.

Palo Alto is growing much faster than IBM. In the January quarter, revenue jumped 19%. The company will report results for the latest quarter on Monday. Palo Alto more than doubled in value last year and its stock is up 6% year to date, lifting the company's market cap past $100 billion. The stock rose more than 1% in extended trading. IBM is up close to 5% this year and is now valued at $154 billion. The companies said the transaction should close by the end of September, subject to regulatory approval and other conditions. [...] IBM will continue to sell its QRadar software for use in on-premises data centers. At the same time, IBM will suggest that clients using it consider switching to Palo Alto's Cortex Xsiam.

'Microsoft's Quest For Short-Term $$$ is Doing Long-Term Damage To Windows, Surface, Xbox, and Beyond' (windowscentral.com) 67

In an op-ed on Windows Central, the site's co-managing editor Jez Corden laments Microsoft's "short-sighted" decision-making and "inconsistent" investment in its products and services, which he argues has led to a loss of trust among customers and missed opportunities in the tech industry. Despite Microsoft's advancements in AI and cloud computing, the company has made "baffling" decisions such as shutting down Windows Phone, under-investing in Xbox, and canceling promising Surface products.

The author argues that Microsoft's lack of commitment to security, customer support, and long-term quality has "damaged" its reputation and hindered its potential for growth. Examples include recent hacking scandals, poor customer service experiences, and the aggressive promotion of Microsoft Edge at the expense of user choice. The author also expresses concern over Microsoft's handling of the Xbox brand, particularly the decision to release exclusive games on PlayStation, which could undermine the reasons for customers to choose Xbox. The op-ed concludes that while Microsoft has the potential to be a leader in the tech industry, its pattern of short-sighted decisions and failure to learn from past mistakes has led to a growing sense of doubt among its customers and observers.

Bay Area City Orders Scientists To Stop Controversial Cloud Brightening Experiment (sfgate.com) 93

Last month, researchers from the University of Washington started conducting an experiment on a decommissioned naval ship in Alameda to test if spraying salt water into the air could brighten clouds and cool the planet. However, their project was forced to stop this month after the city got word of what was going on. SFGate reports: According to a city press release, scientists were ordered to halt the experiment because it violated Alameda's lease with the USS Hornet, the aircraft carrier from which researchers were spraying saltwater into the air using "a machine resembling a snowmaker." The news was first reported by the Alameda Post. "City staff are working with a team of biological and hazardous materials consultants to independently evaluate the health and environmental safety of this particular experiment," the press release states. Specifically, chemicals present in the experiment's aerosol spray are being evaluated to study whether or not they pose any threats to humans, animals or the environment. So far, there isn't any evidence that they do, the city stated.

The prospect of a city-conducted review was not unexpected, the University of Washington said in a statement shared with SFGATE. "In fact, the CAARE (Coastal Aerosol Research and Engagement) facility is designed to help regulators, community members and others engage with the research closely, and we consider the current interactions with the city to be an integral part of that process," the statement reads. "We are happy to support their review and it has been a highly constructive process so far."
The marine cloud brightening (MCB) technique involves spraying fine particles of sea salt into the atmosphere from ships or specialized machines. These sea salt particles are chosen because they are a natural source of cloud-forming aerosols and can increase the number of cloud droplets, making the clouds more reflective. The particles sprayed are extremely small, about 1/1000th the width of a human hair, ensuring they remain suspended in the air and interact with cloud droplets effectively.

By reflecting more sunlight, these brightened clouds can reduce the amount of solar energy reaching the Earth's surface, leading to localized cooling. If implemented on a large scale, this cooling effect could potentially offset some of the warming caused by greenhouse gases.

Walmart's Reign as America's Biggest Retailer Is Under Threat (wsj.com) 48

With Amazon on its heels, the nation's biggest company by revenue is hunting for ways to continue growing. From a report: For a decade, Walmart has reigned as the nation's biggest company by revenue. Its sales last year added up to $648 billion -- more than $1.2 million a minute. That status comes with benefits. It gives Walmart power in negotiations with product manufacturers and in dealing with government officials over policy issues. It's also a point of pride: Job postings often tout working at the "Fortune 1" company as a perk. Its reign is looking shaky lately [non-paywalled link]. If current sales trends persist, Amazon is likely to overtake Walmart soon. Amazon reported $575 billion in total revenue last year, up 12% from the previous year, compared with Walmart's revenue growth of 6%.

Walmart's behemoth size means that to meet its own sales target of around 4% growth each year, the company has to find an additional $26 billion in sales this year. That's no easy task. About 90% of Americans already shop at the retailer. The pandemic and rising inflation boosted Walmart's revenue by $100 billion since 2019. It faces continued uncertainty in consumer confidence and while it's spending in some areas, it's pulling back in others. Earlier this week, Walmart told workers it would cut hundreds of corporate jobs and ask most remote workers to move to offices. While Amazon's and Walmart's businesses compete head on, there are big differences. Amazon earns much of its profit from non-retail operations such as cloud computing and advertising, while grabbing retail market share with fast shipping. Walmart gets the bulk of its sales and profits from U.S. stores, while growing side businesses like advertising and digital sales.

Walmart executives are most wary of Amazon's ability to keep increasing profits through its non-retail business, while eating more of the retail landscape with ever-faster shipping and a bigger product selection, people familiar with the company said. Internally some executives are highlighting Walmart's role as a good corporate citizen and emphasizing that it's important to be the best at serving customers and workers, not just the biggest, say some of those people. Its scale can also have downsides, say some, like outsize attention on every misstep.

VMware Giving Away Workstation Pro, Fusion Pro Free For Personal Use (theregister.com) 90

Dan Robinson reports via The Register: VMware has made another small but notable post-merger concession to users: the Workstation Pro and Fusion Pro desktop hypervisor products will now be free for personal use. The cloud and virtualization biz, now a Broadcom subsidiary, has announced that its Pro apps will be available under two license models: a "Free Personal Use" or a "Paid Commercial Use" subscription for organizations. Workstation Pro is available for PC users running Windows or Linux, while Fusion Pro is available for Mac systems with either Intel CPUs or Apple's own processors. The two products allow users to create a virtual machine on their local computer for the purpose of running a different operating system or creating a sandbox in which to run certain software. [...]

According to VMware, users will get to decide for themselves if their use case calls for a commercial subscription. There are no functional differences between the two versions, the company states, and the only visual difference is that the free version displays the text: "This product is licensed for personal use only." "This means that everyday users who want a virtual lab on their Mac, Windows, or Linux computer can do so for free simply by registering and downloading the bits from the new download portal located at support.broadcom.com," VMware says.
