Intel's Failed 64-bit Itanium CPUs Die Another Death as Linux Support Ends (arstechnica.com) 78

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."

Microsoft Overhauling Its Software Security After Major Azure Cloud Attacks (theverge.com) 40

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 Calls Time on Windows Insider MVP Program (theregister.com) 12

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 Adds Native Support For RAR, 7-Zip, Tar Archive File Formats (techspot.com) 85

"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.

Windows CE Reaches End of Life, If Not End of Sales (theregister.com) 36

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.

When Matthew Perry Met Windows 95 (youtube.com) 60

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.

How Microsoft's AI Investment is Stabilizing Its Cloud Business (nytimes.com) 12

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.

Powerful Malware Disguised as Crypto Miner Infects 1M+ Windows, Linux PCs (pcmag.com) 19

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 Dismisses 'Pretty Insignificant' Arm PC Challenge (theregister.com) 51

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.

PIRG Petitions Microsoft To Extend the Life of Windows 10 (theregister.com) 117

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.

Qualcomm's Snapdragon X Elite Chips Promise Major PC Performance (pcworld.com) 9

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 Admits Giving Up on Windows Phone and Mobile Was a Mistake (theverge.com) 119

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."

Nvidia To Make Arm-Based PC Chips (reuters.com) 42

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."

Microsoft Fixes the Excel Feature That Was Wrecking Scientific Data (theverge.com) 83

An anonymous reader shares a report: In 2020, scientists decided just to rework the alphanumeric symbols they used to represent genes rather than try to deal with an Excel feature that was interpreting their names as dates and (un)helpfully reformatting them automatically. Last week, a member of the Excel team posted that the company is rolling out an update on Windows and macOS to fix that. Excel's automatic conversions are intended to make it easier and faster to input certain types of commonly entered data -- numbers and dates, for instance. But for scientists using quick shorthand to make things legible, it could ruin published, peer-reviewed data, as a 2016 study found.

Microsoft detailed the update in a blog post last week, adding a checkbox labeled "Convert continuous letters and numbers to a date." You can probably guess what that toggles. The update builds on the Automatic Data Conversions settings the company added last year, which included the option for Excel to warn you when it's about to get extra helpful and let you load your file without automatic conversion so you can ensure nothing will be screwed up by it.

Inside Apple's Big Plan to Bring Generative AI To All Its Devices (bloomberg.com) 52

An anonymous reader shares a report: Apple was caught flat-footed when ChatGPT and other AI tools took the technology industry by storm. But the company is now preparing its response and plans to develop features for its full range of devices. One of the most intense and widespread endeavors at Apple right now is its effort to respond to the AI frenzy sweeping the technology industry. The company has some catching up to do. Apple largely sat on the sidelines when OpenAI's ChatGPT took off like a rocket last year. It watched as Google and Microsoft rolled out generative AI versions of their search engines, which spit out convincingly human-like responses to users' queries. Microsoft also updated its Windows apps with smarter assistants, and Amazon unveiled an AI-enhanced overhaul of Alexa. All the while, the only noteworthy AI release from Apple was an improved auto-correct system in iOS 17.

Apple's senior vice presidents in charge of AI and software engineering, John Giannandrea and Craig Federighi, are spearheading the effort. On Cook's team, they're referred to as the "executive sponsors" of the generative AI push. Eddy Cue, the head of services, is also involved, I'm told. The trio are now on course to spend about $1 billion per year on the undertaking. Giannandrea is overseeing development of the underlying technology for a new AI system, and his team is revamping Siri in a way that will deeply implement it. This smarter version of Siri could be ready as soon as next year, but there are still concerns about the technology and it may take longer for Apple's AI features to spread across its product line. Federighi's software engineering group, meanwhile, is adding AI to the next version of iOS. There's an edict to fill it with features running on the company's large language model, or LLM, which uses a flood of data to hone AI capabilities. The new features should improve how both Siri and the Messages app can field questions and auto-complete sentences, mirroring recent changes to competing services.

20 Carriers Face Call-Blocking in the US for Submitting Fake 'Robocall Mitigation Plans' (arstechnica.com) 67

"Twenty phone companies may soon have all their voice calls blocked by US carriers," reports Ars Technica, "because they didn't submit real plans for preventing robocalls on their networks." The 20 carriers include a mix of US-based and foreign voice service providers that submitted required "robocall mitigation" plans to the Federal Communications Commission about two years ago. The problem is that some of the carriers' submissions were blank pages and others were bizarre images or documents that had no relation to robocalls. The strange submissions, according to FCC enforcement orders issued Monday, included "a .PNG file depicting an indiscernible object," a document titled "Windows Printer Test Page," an image "that depicted the filer's 'Taxpayer Profile' on a Pakistani government website," and "a letter that stated: 'Unfortunately, we do not have such a documents.'"

Monday's FCC announcement said the agency's Enforcement Bureau issued orders demanding that "20 non-compliant companies show cause within 14 days as to why the FCC should not remove them from the database for deficient filings." The orders focus on the certification requirements and do not indicate whether these companies carry large amounts of robocall traffic. Each company will be given "an opportunity to cure any deficiencies in its robocall mitigation program description or explain why its certification is not deficient." After the October 30 deadline, the companies could be removed from the FCC's Robocall Mitigation Database.

Removal from the database would oblige other phone companies to block all of their calls.

How Ubuntu Linux Snuck Into High-End Dell Laptops (zdnet.com) 48

Linus Torvalds has said he bought a Dell XPS-13 with Ubuntu Linux for his daughter. Now ZDNet shares some trivia from the history of "the most well-known Linux laptop," citing a presentation by Barton George, Dell Technologies' Developer Community manager, at the Linux/open-source conference All Things Open: First, however, you should know that Dell has supported Linux desktops and laptops since the middle 2000s. In 2006, Michael Dell told me that Dell would be the first major PC vendor to release and support desktop Linux — and this proved to be a success. Barton George explained that Dell had always done great volume with these computers. Not volume, like the Windows machines, of course, but enough that Dell has always offered Linux-based — primarily Red Hat Enterprise Linux (RHEL) powered — workstations.

Still, none of these machines really appealed to developers... George announced on his personal blog what Dell was planning, and his traffic went from 60 views a day to 15,000. Then, as now, there's a lot of interest in laptops that come with Linux ready to go... Dell got together with Canonical, Ubuntu Linux's parent company, to make sure all the drivers were in place for a top-notch Ubuntu Linux developer desktop experience. Indeed, the name 'Project Sputnik' is a nod to Mark Shuttleworth, Ubuntu founder and Canonical CEO. A decade before the project itself, Shuttleworth had spent eight days orbiting the Earth in a Soviet Soyuz spacecraft. George and the crew decided "Soyuz" didn't have an inspiring ring to it, so the company went with "Sputnik" instead.

George continued: "We announced a beta program for the machine with a 10% off offer. We thought, well, we'll probably get 300 people. Instead, we got 6,000. This is where senior management said OK, you've got something real."

Windows 11 Pro's On-By-Default Encryption Slows SSDs Up To 45% 120

An anonymous reader shares a Tom's Hardware report: Unfortunately, a default setting in Windows 11 Pro, having its software BitLocker encryption enabled, robs as much as 45 percent of the speed from your SSD as it forces your processor to encrypt and decrypt everything. According to our tests, random writes and reads -- which affect the overall performance of your PC -- get hurt the most, but even large sequential transfers are affected.

While many SSDs come with hardware-based encryption, which does all the processing directly on the drive, Windows 11 Pro force-enables the software version of BitLocker during installation, without providing a clear way to opt out. (You can circumvent this with tools like Rufus, if you want, though that's obviously not an official solution as it allows users to bypass the Microsoft's intent.) If you bought a prebuilt PC with Windows 11 Pro, there's a good chance software BitLocker is enabled on it right now. Windows 11 Home doesn't support BitLocker so you won't have encryption enabled there.

To find out just how much software BitLocker impacts performance, we ran a series of tests with three scenarios: unencrypted (no BitLocker), software BitLocker (the Windows 11 Pro default), and with hardware BitLocker (OPAL) enabled. While the software encryption increased latency and decreased transfer rates, hardware encryption and no encryption at all were basically tied. If you have software BitLocker enabled, you may want to change your settings.
