An anonymous reader quotes a report from Motherboard: [A] new tech startup, Prophetic, aims to bring lucid dreams to a much wider audience by developing a wearable device designed to spark the experience when desired. Prophetic is the brainchild of Eric Wollberg, its chief executive officer, and Wesley Louis Berry III, its chief technology officer. The pair co-founded the company earlier this year with the goal of combining technologies, such as ultrasound and machine learning models, "to detect when dreamers are in REM to induce and stabilize lucid dreams" with a device called the Halo according to the company's website. [...]

Prophetic does not make any medical claims about its forthcoming products -- Halo is tentatively slated for a 2025 release -- though Wollberg and Berry both expressed optimism about broader scientific research that suggests lucid dreams can reduce PTSD-related nightmares, promote mindfulness, and open new windows into the mysterious nature of consciousness. To explore those links further, Prophetic has partnered with the Donders Institute, a research center at Radboud University in the Netherlands that is focused on neuroscience and cognition, to generate the largest dataset of electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) observations of lucid dreamers, according to the company. The collaboration will also explore one of central technologies behind Prophetic's vision, known as transcranial focused ultrasound (TUS). This non-invasive technique uses low-intensity ultrasound pulses to probe the brain, and interact with neural activity, with a depth and precision that cannot be achieved with previous methods, such as transcranial electrical stimulation or transcranial magnetic stimulation.

At this point, both the possibilities and limits of Prophetic's concept remain unclear. While ultrasound devices have been widely used in medicine for decades, the process of stimulating parts of the brain with TUS is a relatively new development. Within the past few years, scientists have shown that TUS "has the potential to be used both as a scientific instrument to investigate brain function and as a therapeutic modality to modulate brain activity," according to a 2019 study, and "could be a useful tool in the treatment of clinical disorders characterized by negative mood states, like depression and anxiety disorders," according to a 2020 study. What is not known, yet, is whether TUS can induce or stabilize lucid dreams, though the Prophetic team is banking on a positive answer to this open question. Its wearable headband prototype, the Halo, was developed with the company Card79 and can currently read EEG data of users. Over the next year, Prophetic aims to use the dataset from their partnership with the Donders Institute to train machine learning models that will stimulate targeted neural activity in users with ultrasound transducers as a means of inducing lucid dreams.

Bill Gates, noted billionaire philanthropist, discussed the need for "impatient optimism" about both climate change and global development last month during an interview at an international affairs think tank: Q: If you go back a decade, are you more or less optimistic about where we are on climate change now, or then?

Bill Gates: I'm certainly more optimistic because in 2015, when the Paris Agreement was signed, there were so many areas of emission where there wasn't any activity...

Q: if you go back a decade, solar and wind were the most expensive energy sources we had. Since then, the price of solar has dropped 90%, and the price of wind has dropped 70%, and electric vehicles are now economically viable... I know you get excited about innovation. What are some of the areas that you're most excited about for innovation?

Bill Gates: Across this portfolio of 100 companies it's hard to pick my favorite. Some are kind of straightforward, like a company that makes windows where the temperature doesn't cross over, but instead, it blocks getting cold in the winter or hot in the summer, which is very cheap. Or there is a company where you leave your home, and you pump this air through, but it's got a chemical in it. When it sees cracks, it actually seals those cracks. You don't have to find the cracks; you just pump the air in. You can reduce the amount of heat loss between the windows and getting rid of those cracks. You can reduce the energy bill by a factor of two, which then means less load on the overall energy system...

The cement and steel ones are the ones, in a way, I'm most impressed by, because I wasn't sure we'd find anything in those spaces...

Q: The problem, I guess, with cement is that you are taking basically limestone, and then you are converting it to calcium oxide. But the byproduct you get in that conversion process is CO2. Basically, you need a way to capture that CO2....

Bill Gates: As you heat the limestone, that releases CO2. It's exactly as you say, it's an equal number amount of emissions. One of our companies doesn't use limestone. They actually go and find another source of calcium, which fortunately turns out to be quite abundant and cheap. They make exactly the same cement that we make today, but not using limestone as the input. I was stunned that you could do that.
Gates also hopes to see nuclear power in an economically viable form. "The nuclear industry basically failed, because their product was too expensive. It wasn't because of the waste or safety-type issues, which we can get into those, but it was economics." Bill Gates: First and foremost, you must have a much different economic proposition. The nuclear reactor I'm involved in, TerraPower, we only generate electricity when the renewable sources that have very little marginal costs aren't generating. We just make heat all day, and then only when the bid price of electricity is high enough, do we actually generate electricity, because otherwise, you have all this capital cost that half the time, the solar bid into that market is going to be very low.

I think fission, we shouldn't give up on it. I'm involved in that company only because it may be able to make a significant contribution to [fighting] climate change... I can't overstate how much easier it is to solve the problem if you can mix in some degree of fission or fusion that are there to fill in the periods where renewables are not generating. Cold snaps or where you have these cold fronts just sitting there, that's when houses need the most heating. That's when neither wind nor solar are generating.

It happened a quarter of a century ago. The New York Times wrote that "An internal memorandum reflecting the views of some of Microsoft's top executives and software development managers reveals deep concern about the threat of free software and proposes a number of strategies for competing against free programs that have recently been gaining in popularity." The memo warns that the quality of free software can meet or exceed that of commercial programs and describes it as a potentially serious threat to Microsoft. The document was sent anonymously last week to Eric Raymond, a key figure in a loosely knit group of software developers who collaboratively create and distribute free programs ranging from operating systems to Web browsers. Microsoft executives acknowledged that the document was authentic...

In addition to acknowledging that free programs can compete with commercial software in terms of quality, the memorandum calls the free software movement a "long-term credible" threat and warns that employing a traditional Microsoft marketing strategy known as "FUD," an acronym for "fear, uncertainty and doubt," will not succeed against the developers of free software. The memorandum also voices concern that Linux is rapidly becoming the dominant version of Unix for computers powered by Intel microprocessors.

The competitive issues, the note warns, go beyond the fact that the software is free. It is also part of the open-source software, or O.S.S., movement, which encourages widespread, rapid development efforts by making the source code — that is, the original lines of code written by programmers — readily available to anyone. This enables programmers the world over to continually write or suggest improvements or to warn of bugs that need to be fixed. The memorandum notes that open software presents a threat because of its ability to mobilize thousands of programmers. "The ability of the O.S.S. process to collect and harness the collective I.Q. of thousands of individuals across the Internet is simply amazing," the memo states. "More importantly, O.S.S. evangelization scales with the size of the Internet much faster than our own evangelization efforts appear to scale."
Back in 1998, Slashdot's CmdrTaco covered the whole brouhaha — including this CNN article: A second internal Microsoft memo on the threat Linux poses to Windows NT calls the operating system "a best-of-breed Unix" and wonders aloud if the open-source operating system's momentum could be slowed in the courts.

As with the first "Halloween Document," the memo — written by product manager Vinod Valloppillil and another Microsoft employee, Josh Cohen — was obtained by Linux developer Eric Raymond and posted on the Internet. In it, Cohen and Valloppillil, who also authored the first "Halloween Document," appear to suggest that Microsoft could slow the open-source development of Linux with legal battles. "The effect of patents and copyright in combating Linux remains to be investigated," the duo wrote.
Microsoft's slogain in 1998 was "Where do you want to go today?" So Eric Raymond published the documents on his web site under the headline "Where will Microsoft try to drag you today? Do you really want to go there?"

25 years later, and it's all still up there and preserved for posterity on Raymond's web page — a collection of leaked Microsoft documents and related materials known collectively as "the Halloween documents." And Raymond made a point of thanking the writers of the documents, "for authoring such remarkable and effective testimonials to the excellence of Linux and open-source software in general."

Thanks to long-time Slashdot reader mtaht for remembering the documents' 25th anniversary...

Microsoft has updated its Surface support documentation, committing to supporting some Surface Pcs with six years of firmware updates -- up from the four years it originally offered. Windows Central reports: The updated documentation states that any Surface PC shipped after January 1, 2021 will receive six years of firmware updates. Surface devices shipped before that date will remain on four years of firmware updates. This means Surface Pro 7+, Surface Go 3, Surface Laptop 4, Surface Laptop Go 2, Surface Studio 2+, Surface Laptop Studio 1 and newer have all had their support cycles extended by two additional years.

Here's what the documentation says:

- For devices released before January 1, 2021: Surface devices will receive driver and firmware updates for at least four years from when the device was first released. In cases where the support duration is longer than four years, an updated end-of-servicing date will be published before the date of the last servicing.
- For devices released on and after January 1, 2021: Surface devices will receive driver and firmware updates for at least six years from when the device was first released. In cases where the support duration is longer than six years, an updated end-of-servicing date will be published before the date of the last servicing.

Long-time Slashdot reader williamyf writes: In the ongoing battle between Red Hat and other "Enterprise Linux -- RHEL compatible" distros, today the OpenELA (Open Enterprise Linux Association), a body Consisting of CIQ (stewards of Rocky Linux), Oracle and Suse, released source code for a generic "Enterprise Linux Distro" (Sources available for RHEL 8 and RHEL 9). A Steering committee for the foundation was also formed.

War between Red Hat and what they call "clones" (mostly Oracle; CentOS, Rocky, Alma and others seem to be collateral damage) has been raging on for years. First, in 2011, Red Hat changed the way they distributed kernel patches. Then, in 2014, Red Hat absorbed CentOS. In 2019 Red Hat transformed CentOS to CentOS stream, and shortened support Timetables for CentOS 8, all out of the blue. Then, in 2023, RedHat severely restricted source code access to non-customers.

What will be RedHat's reaction to this development? My bet is that they will stop to release source code of distro modules under BSD, MIT, APACHE and MPL Licenses for RHEL and in certain Windows for CentOS Stream. What is your bet? Let us know in the comments.

Officially, Intel's Itanium chips and their IA-64 architecture died back in 2021, when the company shipped its last processors. But failed technology often dies a million little deaths. From a report: To name just a few: Itanium also died in 2013, when Intel effectively decided to stop improving it; in 2017, when the last new Itanium CPUs shipped; in 2020, when the last Itanium-compatible version of Windows Server stopped getting updates; and in 2003, when AMD introduced a 64-bit processor lineup that didn't break compatibility with existing 32-bit x86 operating systems and applications.

Itanium is dying another death in the next version of the Linux kernel. According to Phoronix, all code related to Itanium support is being removed from the kernel in the upcoming 6.7 release after several months of deliberation. Linus Torvalds removed some 65,219 lines of Itanium-supporting code in a commit earlier this week, giving the architecture a "well-earned retirement as planned."

An anonymous reader shares a report: Microsoft has had a rough few years of cybersecurity incidents. It found itself at the center of the SolarWinds attack nearly three years ago, one of the most sophisticated cybersecurity attacks we've ever seen. Then, 30,000 organizations' email servers were hacked in 2021 thanks to a Microsoft Exchange Server flaw. If that weren't enough already, Chinese hackers breached US government emails via a Microsoft cloud exploit earlier this year. Something had to give.

Microsoft is now announcing a huge cybersecurity effort, dubbed the Secure Future Initiative (SFI). This new approach is designed to change the way Microsoft designs, builds, tests, and operates its software and services today. It's the biggest change to security efforts inside Microsoft since the company announced its Security Development Lifecycle (SDL) in 2004 after Windows XP fell victim to a huge Blaster worm attack that knocked PCs offline in 2003. That push came just two years after co-founder Bill Gates had called on a trustworthy computing initiative in an internal memo.

Microsoft now plans to use automation and AI during software development to improve the security of its cloud services, cut the time it takes to fix cloud vulnerabilities, enable better security settings out of the box, and harden its infrastructure to protect against encryption keys falling into the wrong hands. In an internal memo to Microsoft's engineering teams today, the company's leadership has outlined its new cybersecurity approach. It comes just months after Microsoft was accused of "blatantly negligent" cybersecurity practices related to a major breach that targeted its Azure platform. Microsoft has faced mounting criticism of its handling of a variety of cybersecurity issues in recent years.

Microsoft has decided to axe the Windows Insider MVP program, which is now scheduled to be discontinued at the end of the year. From a report: A Microsoft spokesperson told The Register: "In an effort to consolidate MVP-style programs across Microsoft, we have decided to retire the Windows Insider MVP Program effective December 31, 2023. All our existing Windows Insider MVPs will be nominated to participate in the Microsoft MVP Program which has similar benefits and opportunities to continue networking with us and interacting with many other Microsoft MVPs globally."

The Windows Insider MVPs are usually enthusiasts of Microsoft's wares who are rewarded for their loyalty with access to the engineering teams, complimentary subscriptions to products such as Visual Studio Enterprise and Office 365, as well as the odd paperweight or two. A nomination must come from another MVP or a Microsoft employee to achieve this coveted status. An application is then scrutinized, and if one has demonstrated sufficient passion for all things Microsoft, the nod is given. Microsoft has plenty of Insider programs where users can play with pre-release versions of the company's software.

"Windows 11's last major update, 22H2 introduced native support for managing RAR archives, eliminating the need for third-party software," writes Slashdot reader jjslash. "This enhancement is part of the OS's broader capability improvements for handling various archive file formats." TechSpot reports: Microsoft finally introduced native support for RAR archives earlier this year, just three decades after the format's official introduction in 1993. Windows 11 development is now progressing at an accelerated pace, therefore support for a whole lot of new (ancient) archive formats is coming soon.

Microsoft recently released KB5031455, an optional, feature-rich preview cumulative update for Windows 11, refreshing the list of archive formats natively supported in the OS. Windows 11 22H2 and later versions can now manage files compressed in the following archive types: .rar, .7z, .tar, .tar.gz, .tar.bz2, .tar.zst, .tar.xz, .tgz, .tbz2, .tzst, .txz. Support for password-encrypted archives is not available yet.

Redmond programmers added support for the aforementioned archive files thanks to the libarchive library, an open source project designed to develop a portable, efficient C library that can "read and write streaming archives" in a variety of formats. Libarchive supports additional archive types (Lzh, Xar) that could eventually come to Windows 11 as well.

Microsoft's dedicated OS for embedded and pocket devices, Windows CE, has reached the end of its support lifetime. From a report: Windows CE -- and there's never been an official explanation of what the WinCE-inducing name stood for -- debuted in November 1996, just a few months after Windows NT 4, the first version of NT with the Explorer desktop from Windows 95. Earlier this month, as reported by HPC Factor, the last ever version, CE 8, branded Compact Embedded 2013, reached its end of support.

In 2011, Microsoft said it would be replaced by a unified platform based on Windows 8, but we know how well that went down. By 2020, the official migration path was set -- to a container on top of Win10 IoT. Its fortunes have always fluctuated. In 1999, we asked does MS care about WinCE? By 2003, we reported that eTForecasts said it would outship PCs. Indirectly, the researchers were right -- smartphones did end up massively outselling PCs. They just weren't Microsoft ones.

Long-time Slashdot reader destinyland writes: In 1994 the TV show Friends premiered, and its first season's high ratings made it the 8th most-popular show. The next year Microsoft released Windows 95 — and filmed a promotional video for it with 25-year-old Matthew Perry and 26-year-old Jennifer Aniston.

"They'll be taking you on an adventure in computing that takes place in the office of Microsoft chairman Bill Gates," explains the video's narrator, adding "Along the way, they meet a wacky bunch of propellor-heads.... And are introduced the top 25 features of Windows 95!"

It's a journey back in time. (At one point the video refers to Windows as the operating system "with tens of millions of users.") Their 30-minute segment — billed as "the world's first cyber sitcom" — appears in an hour-long video introducing revolutionary features like the new "Start" button. Also demonstrated in Excel are the new minimize and maximize "features" in "the upper right-side of the window". And the two actors marvel at the ability to type a filename that was longer than eight characters...

Watch for reminders that The Microsoft Windows 95 Video Guide was filmed nearly three decades ago. When the desktop appears after waking from screensaver mode, Perry notes that there's "no messy DOS build-up." And later the video reminds viewers that Windows 95 is compatible "with DOS games like Flight Simulator." There's also a brand new feature called "Windows Explorer" (which is described as "File Manager on steroids"), as well as a new "Find" option, and a brand new icon named "My Computer". And near the end they pay a visit to the Microsoft Network — which was mostly a "walled garden" online service — described in the video as "your on-ramp to the information superhighway".

The video even explains how Windows 95 "uses the right mouse button for what Microsoft calls power users."

And by the end of it, Jennifer Anniston finds herself playing Space Cadet 3D pinball.

ZDNet reports an interesting static from Microsoft's CEO Satya Nadella. "We have over 1 million paid Copilot users in more than 37,000 organizations that subscribe to Copilot for business, with significant traction outside the United States."

And Microsoft's quarterly results also "showed early signs that the company's investments in generative AI were beginning to bolster sales, most notably reversing what had been slowing growth of the company's important cloud computing product," reports the New York Times. (Alternate URL here.) The company had $56.5 billion in sales in the three months that ended in September, up 13% from a year earlier. Profit hit $22.3 billion, up 27%. The results beat analyst expectations and Microsoft's own estimates.

Microsoft had told investors that A.I. wouldn't start producing meaningful results until after the start of 2024, when more products became widely available. The company and its competitors are racing to put generative A.I. into nearly every product they offer. Microsoft is seen by many companies as a leading A.I. provider, thanks to its partnership with — and $13 billion investment in — the start-up OpenAI, which introduced the chatbot ChatGPT almost a year ago. Microsoft's flagship cloud computing product, Azure, grew 29%, up from 26% in the previous quarter. About three percentage points of Azure's growth came from generative A.I. products, including the access Microsoft provides to OpenAI's GPT-4 language model, more than the company had told investors to expect.

More than 18,000 organizations are using Microsoft's Azure OpenAI services, Satya Nadella, the company's chief executive, said in a call with investors. He said that included customers who had not used Azure before. "Azure again took share as organizations took their workloads to our cloud," Mr. Nadella said... The company said that sales could increase as much as 8.7% in the current quarter, exceeding investor expectations, and that it was investing in building data centers to support the demand for A.I. and cloud computing...

Microsoft's personal computing business grew just 3%, to $13.7 billion, reflecting how consumer behaviors have shifted since the laptop-buying binges of the pandemic. The revenue of the Windows operating system installed on new computers was up 4%. Gaming provided a consumer bright spot, with Xbox content and services up 13%.
Next month Microsoft integrates its Copilot AI product into its Excel/Word/Teams "productivity suite" — but Microsoft CEO Satya Nadella said that 40% of Fortune 100 companies have already been testing the feature during its "limited preview", and "so far, so good."

Yet the article notes it isn't all good news for Microsoft. Investment bank UBS has told investors that while Microsoft integrated an AI-powered chatbot into its Bing search engine, there is "no evidence" that Bing has actually gained any search market share.

PC Magazine reports: A powerful piece of malware has been disguising itself as a trivial cryptocurrency miner to help it evade detection for more than five years, according to antivirus provider Kaspersky. This so-called "StripedFly" malware has infected over 1 million Windows and Linux computers around the globe since 2016, Kaspersky says in a report released Thursday...

StripedFly incorporated a version of EternalBlue, the notorious NSA-developed exploit that was later leaked and used in the WannaCry ransomware attack to infect hundreds of thousands of Windows machines back in 2017. According to Kaspersky, StripedFly uses its own custom EternalBlue attack to infiltrate unpatched Windows systems and quietly spread across a victim's network, including to Linux machines. The malware can then harvest sensitive data from infected computers, such as login credentials and personal data. "Furthermore, the malware can capture screenshots on the victim's device without detection, gain significant control over the machine, and even record microphone input," the company's security researchers added.

To evade detection, the creators behind StripedFly settled on a novel method by adding a cryptocurrency mining module to prevent antivirus systems from discovering the malware's full capabilities.

Intel CEO Pat Gelsinger has downplayed the threat of rival chipmakers creating processors based on the Arm architecture for PCs. From a report: "Arm and Windows client alternatives, generally they've been relegated to pretty insignificant roles in the PC business," he told analysts during the x86 giant's Q3 earnings call Thursday. "We take all our competition seriously, but I think history is our guide here. We don't see these as potentially being all that significant overall," he added, a sentiment somewhat at odds with Microsoft which last week cited analyst research predicting Arm's PC market share will grow from its curernt 14 percent to 25 percent by 2027.

Which seems far from "pretty insignificant." Gelsinger's words also contrast markedly with past Intel CEO Andy Grove, who penned a book titled "Only the Paranoid Survive: How to Exploit the Crisis Points That Challenge Every Company." While Gelsinger doesn't see Arm as a threat, he said Intel Foundry Services is more than happy to work with chipmakers to build chips based on the architecture. "When you're thinking about other alternative architectures like Arm, we also say, 'Wow, what a great opportunity for our foundry'," he said. To that end, the in April 2023 the chipmaker announced a strategic partnership with Arm to make it easier to produce chips on the architecture in Intel foundries.

An anonymous reader shares a report: Microsoft is starting to roll out new changes to Windows Ink that let you write anywhere you can type in Windows 11. After months of previewing the changes, the handwriting-to-text conversion now works inside search boxes and other elements of Windows 11 where you'd normally type your input. [...] If you have a Surface device with a stylus or any other Windows tablet that supports Windows Ink then you'll immediately see this new feature if you head into Settings and start to write into a search box, or in other text edit fields in Windows 11.

The Public Interest Research Group (PIRG) has delivered a petition to Microsoft calling on the company to rethink the impending abandonment of Windows 10 in the face of millions of PCs potentially being rendered eligible for landfill overnight. From a report: There are now less than two years until Microsoft is due to cut support for Windows 10, and at current estimates, 400 million PCs can't make the jump to Windows 11. The petition, addressed to Microsoft CEO Satya Nadella, criticizes its plans and states that customers expect their devices to last rather than be rendered obsolete by an arbitrary decision. PIRG warns that tipping that much hardware into landfills is somewhat at odds with the company's stance on the environment.

The petition reads: "All software reaches a point at which it's no longer supported, but when the consequences to our environment are this large we shouldn't accept it." As a reminder, while Windows 10 was largely backwards-compatible with computers running older operating systems, Microsoft slapped hardware requirements on Windows 11 that rendered machines even just a few years old unable to upgrade -- the main issues center on the CPU and TPM requirements.

iFixit has started selling genuine replacement parts for Microsoft Surface devices. From a report: The company now offers SSDs, batteries, screens, kickstands, and a whole bunch of other parts for 15 Surface products. Some of the devices on that list include the Surface Pro 9, Surface Laptop 5, Surface Go 4, Surface Studio 2 Plus, and others. You can check out the entire list of supported products and parts in this post on Microsoft's website. In addition to supplying replacement parts, iFixit also offers disassembly videos and guides for each product, as well as toolkits that include things like an opening tool, tweezers, drivers, and more.

Qualcomm unveiled a new laptop processor designed to outperform rival products from Intel and Apple on Tuesday, stepping up its long-running effort to break into the personal computer market. From a report: Qualcomm formally launched the Snapdragon X Elite, the flagship platform of its Snapdragon X family that leverages its Oryon CPU core, and promises to double -- yes, double -- the performance of some of the most popular 13th-gen Core chips from AMD and Intel. Sound familiar? It should. Qualcomm promised the same with its earlier Snapdragon 8-series chips, and really didn't deliver. But after buying chip designer Nuvia in 2021, Qualcomm is trying again, hoping that its superpowered Arm chips can once again make Windows on Arm PCs a competitor to conventional X86 PCs when they launch in mid-2024. And they'e talking some big numbers to prove it.

Qualcomm sees Oryon first going into PCs (as the engine of the Snapdragon X Elite platform) but then moving into smartphones, cars, "extended reality" devices, and more, Qualcomm chief executive Cristiano Amon is expected to say today. [...] To begin with, Qualcomm's Snapdragon X Elite is manufactured on a 4nm process node, versus the Intel 4 process node of Intel's Meteor Lake. (The two process technologies aren't directly comparable, though they're close enough for most purposes.) Oryon is a tri-cluster design. Historically, that has meant prime, performance, and efficiency cores, with each type of core taking on their own role depending upon the task. However, it appears that Qualcomm and its X86 rivals may have swapped strategies; as Intel adopts performance and efficiency cores, Qualcomm has chosen AMD's path. There are twelve cores within the Snapdragon X Elite, all running at 3.8GHz. Well, most of the time. If needed one or two of the cores can boost to 4.3GHz, the turbo boost strategy that's become common on the PC. The 64-bit Oryon CPU will be paired with 42Mbytes of total cache, and a memory controller that can access eight channels of LPDDR5x memory (64GB in total) with 130GBps memory bandwidth, executives said. It will be a single die, not a chiplet design.

Microsoft CEO Satya Nadella is the third chief executive of the software giant to admit the company has made some serious mobile mistakes. From a report: Satya Nadella took over from former CEO Steve Ballmer in 2014 and, just over a year later, wrote off $7.6 billion related to Microsoft's acquisition of the Nokia phone business. In an interview with Business Insider, Nadella admitted that Microsoft's "exit" from the mobile phone business could have been handled better. Asked about a strategic mistake or wrong decision that he might regret, Nadella responds: "The decision I think a lot of people talk about -- and one of the most difficult decisions I made when I became CEO -- was our exit of what I'll call the mobile phone as defined then. In retrospect, I think there could have been ways we could have made it work by perhaps reinventing the category of computing between PCs, tablets, and phones."

According to Reuters, Nvidia is designing ARM-based processors that would run Microsoft's Windows operating system. While they're not expected to be ready until 2025, it poses a major new challenge to Intel which has long dominated the PC industry. From the report: The AI chip giant's new pursuit is part of Microsoft's effort to help chip companies build Arm-based processors for Windows PCs. Microsoft's plans take aim at Apple, which has nearly doubled its market share in the three years since releasing its own Arm-based chips in-house for its Mac computers, according to preliminary third-quarter data from research firm IDC. Advanced Micro Devices also plans to make chips for PCs with Arm technology, according to two people familiar with the matter. Nvidia and AMD could sell PC chips as soon as 2025, one of the people familiar with the matter said. Nvidia and AMD would join Qualcomm, which has been making Arm-based chips for laptops since 2016. At an event on Tuesday that will be attended by Microsoft executives, including vice president of Windows and Devices Pavan Davuluri, Qualcomm plans to reveal more details about a flagship chip that a team of ex-Apple engineers designed, according to a person familiar with the matter.

Nvidia, AMD and Qualcomm's efforts could shake up a PC industry that Intel long dominated but which is under increasing pressure from Apple. Apple's custom chips have given Mac computers better battery life and speedy performance that rivals chips that use more energy. Executives at Microsoft have observed how efficient Apple's Arm-based chips are, including with AI processing, and desire to attain similar performance, one of the sources said. Microsoft has been encouraging the involved chipmakers to build advanced AI features into the CPUs they are designing. The company envisions AI-enhanced software such as its Copilot to become an increasingly important part of using Windows. To make that a reality, forthcoming chips from Nvidia, AMD and others will need to devote the on-chip resources to do so. "Microsoft learned from the 90s that they don't want to be dependent on Intel again, they don't want to be dependent on a single vendor," said Jay Goldberg, chief executive of D2D Advisory, a finance and strategy consulting firm. "If Arm really took off in PC (chips), they were never going to let Qualcomm be the sole supplier."
