MojoKid writes: AMD made bold claims when the company unveiled its new Zen 3-based Ryzen 5000 series processors early last month. Statements like "historic IPC uplift" and "fastest for gamers" were waved about like flags of victory. However, as with most things in the computing world, independent testing is always the best way to validate claims. Today AMD lifted the embargo on 3rd party reviews and, in testing, AMD's new Ryzen 5000 series CPUs set a new performance bar virtually across the board, and one that Intel currently can't touch. There are four processors in the initial Ryzen 5000 series lineup, though it's a safe bet more will be coming later. The current entry point is the Ryzen 5 5600X 6-core / 8-thread processor, followed by the 8-core / 16-thread Ryzen 7 5800X, 12-core / 24 thread Ryzen 9 5900X, and the flagship 16-core / 32-thread Ryzen 9 5950X. All of these new CPUs are backwards compatible with AMD socket AM4 motherboards. In comparison to Zen 2, Zen 3 has a larger L1 branch target buffer and improved bandwidth through multiple parts of its pipeline with additional load/store flexibility. Where Zen 2 could handle 2 load and 1 store per cycle, Zen 3 can handle 3 load and 2 stores. All told, AMD is claiming an average 19% increase in IPC with Zen 3, which is a huge uplift gen-over-gen. Couple that IPC uplift with stronger multi-core scaling and a new unified L3 cache configuration, and Zen 3's performance looks great across a wide variety of workloads for both content creation and gaming especially. AMD's Ryzen 9 5950X, Ryzen 9 5900X, Ryzen 7 5800X and Ryzen 5 5600X will be priced at $799, $549, $449 and $299, respectively and should be on retail and etail shelves starting today.

Gaming hardware makers have been diversifying their laptops recently, and Razer is the latest to join that trend. From a report: The company is announcing the Razer Book 13 today, which it's calling a "hyper focused productivity laptop." It's not just a subtler version of a Blade laptop, either. The emphasis on productivity means Razer also strove to include a generous array of ports, as well as interesting lighting features that could help highlight keyboard shortcuts. The Book 13 is also the company's first Intel Evo-certified notebook, meaning it meets certain requirements for performance, battery life and wake time. As its name indicates, the Book 13 has a 13.4-inch IPS display that comes in touch or nontouch configurations. If you opt for the matte nontouch version, you'll only get Full HD+ resolution, while the touch models also come in UHD+ (3,840 x 2,400). The touchscreens are also covered in Gorilla Glass for better durability and you can add an anti-reflective coating to reduce glare. All configurations feature a 16:10 aspect ratio, which is new to Razer's family of laptops and lets you see more on the screen at once than older 16:9 devices.

The Book 13 also houses a 720p webcam in its slim bezels, and it's Windows Hello-compatible. There isn't a fingerprint scanner here, though. That's understandable -- Razer's already crammed a lot into the Book 13, which is impressive for a device thatâ(TM)s 0.6 inches thick and weighs 2.95 pounds. Plus, despite that sharp profile, the company managed to offer two Thunderbolt 4 USB-C ports, a USB-A socket (at USB 3.2 speeds), a microSD card reader, a 3.5mm audio jack and an HDMI 2.0 slot. [...] The slim, lightweight package is something Razer fans are already accustomed to, and they'll also appreciate some other familiar features. The most prominent of these is Razer Chroma integration which allows users to customize the colors of individual buttons on the keyboard. Starts at $1,199. Pre-order starts today, with shipping to be followed later this month.

An anonymous reader quotes a report from Ars Technica: This weekend, Intel released preliminary information on its newest laptop part -- the Xe Max discrete GPU, which functions alongside and in tandem with Tiger Lake's integrated Iris Xe GPU. We first heard about Xe Max at Acer's Next 2020 launch event, where it was listed as a part of the upcoming Swift 3x laptop -- which will only be available in China. The new GPU will also be available in the Asus VivoBook Flip TP470 and the Dell Inspiron 15 7000 2-in-1.

During an extended product briefing, Intel stressed to us that the Xe Max beats Nvidia's entry-level MX 350 chipset in just about every conceivable metric. In another year, this would have been exciting -- but the Xe Max is only slated to appear in systems that feature Tiger Lake processors, whose Iris Xe integrated GPUs already handily outperform the Nvidia MX 350 in both Intel's tests and our own. The confusion here largely springs from mainstream consumer expectations of a GPU versus what Intel's doing with the Xe Max. Our GPU tests largely revolve around gaming, using 3DMark's well-known benchmark suite, which includes gaming, fps-focused tests such as Time Spy and Night Raid. Intel's expectations for the Xe Max instead revolve, almost entirely, around content creation with a side of machine learning and video encoding.

Xe Max is, roughly speaking, the same 96 Execution Unit (EU) GPU to be found in the Tiger Lake i7-1185G7 CPU we've tested already this year -- the major difference, beyond not being on-die with the CPU, is a higher clock rate, dedicated RAM, and separate TDP budget. Tiger Lake's Iris Xe has a peak clock rate of 1.35GHz, and it shares the CPU's TDP constraints. Iris Xe Max has its own 25W TDP and a higher peak clock rate of 1.65GHz. It also has its own 4GiB of dedicated RAM -- though that RAM is the same LPDDR4X-4266 that Tiger Lake itself uses, which is something of a first for discrete graphics and might lead to better power efficiency.

More than 23,000 hacked databases have been made available for download on several hacking forums and Telegram channels in what threat intel analysts are calling the biggest leak of its kind. From a report: The database collection is said to have originated from Cit0Day.in, a private service advertised on hacking forums to other cybercriminals. Cit0day operated by collecting hacked databases and then providing access to usernames, emails, addresses, and even cleartext passwords to other hackers for a daily or monthly fee. Cybercriminals would then use the site to identify possible passwords for targeted users and then attempt to breach their accounts at other, more high-profile sites. The idea behind the site isn't unique, and Cit0Day could be considered a reincarnation of similar "data breach index" services such as LeakedSource and WeLeakInfo, both taken down by authorities in 2018 and 2020, respectively.

According to The Oregonian, Intel is "openly flirting with the notion of moving leading-edge production from Oregon to Asia and hiring one of its top rivals to make Intel's most advanced chips." The decision is likely in January. From the report: It's a momentous choice that follows a string of manufacturing setbacks at the Ronler Acres campus near Hillsboro Stadium, failures that have cost Intel its cherished leadership in semiconductor technology -- perhaps forever. Outsourcing wouldn't shutter Intel's Oregon factories or close down its Hillsboro research labs. The company says it's committed to maintaining its advanced research and retaining internal production capacity. It's continuing a massive expansion of its D1X factory in Hillsboro.

In time, though, Oregon's central role in Intel's technology would almost surely erode if the company cedes manufacturing leadership to rivals overseas. Chip industry analyst Dan Hutcheson of VLSI Research believes that transition could render Oregon "irrelevant" if Intel gradually shifts away from integrated research and manufacturing. "Companies say they're making a transition. What they find is they're stepping off a cliff," Hutcheson said. "They're going down a road that you can't easily go back on."

CEO Bob Swan told Wall Street analysts on a conference call earlier this month that it may outsource advanced production to its rivals -- he named Taiwan Semiconductor Manufacturing Co., specifically -- to ensure "a predictable cadence of leadership products." Swan told investors to expect a decision by late January. Intel already outsources as much as a fifth of its production but has kept the leading edge in Oregon. And whatever it decides on outsourcing, Swan said Intel will maintain its advanced research -- science performed in Hillsboro -- which he described as "a powerful force in creating future differentiation for our products." On this month's analyst call, Swan said Intel believes it can have it both ways -- sending advanced production overseas while retaining internal production for components and older products that don't require the most sophisticated technology. And Swan said Intel believes it could restore advanced manufacturing to its own factories sometime in the future, if it chooses to.

SiFive today announced it is creating a platform for Linux-based personal computers based on RISC-V processors. VentureBeat reports: Assuming customers adopt the processors and use them in PCs, the move might be part of a plan to create Linux-based PCs that use royalty-free processors. This could be seen as a challenge to computers based on designs from Intel, Advanced Micro Devices, Apple, or Arm, but giants of the industry don't have to cower just yet. The San Mateo, California-based company unveiled HiFive Unmatched, a development design for a Linux-based PC that uses its RISC-V processors. At the moment, these development PCs are early alternatives, most likely targeted at hobbyists and engineers who may snap them up when they become available in the fourth quarter for $665.

The SiFive HiFive Unmatched board will have a SiFive processor, dubbed the SiFive FU740 SoC, a 5-core processor with four SiFive U74 cores and one SiFive S7 core. The U-series cores are Linux-based 64-bit application processor cores based on RISC-V. These cores can be mixed and matched with other SiFive cores, such as the SiFive FU740. These components are all leveraging SiFive's existing intellectual property portfolio. The HiFive Unmatched board comes in the mini-ITX standard form factor to make it easy to build a RISC-V PC. SiFive also added some standard industry connectors -- ATX power supplies, PCI-Express expansion, Gigabit Ethernet, and USB ports are present on a single-board RISC-V development system.

The HiFive Unmatched board includes 8GB of DDR4 memory, 32MB of QSPI flash memory, and a microSD card slot on the motherboard. For debugging and monitoring, developers can access the console output of the board through the built-in microUSB type-B connector. Developers can expand it using PCI-Express slots, including both a PCIe general-purpose slot (PCIe Gen 3 x8) for graphics, FPGAs, or other accelerators and M.2 slots for NVME storage (PCIe Gen 3 x4) and Wi-Fi/Bluetooth modules (PCIe Gen 3 x1). There are four USB 3.2 Gen 1 type-A ports on the rear, next to the Gigabit Ethernet port, making it easy to connect peripherals. The system will ship with a bootable SD card that includes Linux and popular system developer packages, with updates available for download from SiFive.com. It will be available for preorders soon.
For some more context: Could RISC-V processors compete with Intel, ARM, and AMD?

As expected, Apple has announced a third fall media event, "One More Thing," focused on the first Mac computers with ARM technology-based Apple Silicon processors. The event will take place on November 10, 2020, and will be streamed from the company's Apple Park headquarters starting at 10:00a.m. Pacific Time. From a report: "One More Thing" was originally a phrase used at media events by Apple's late CEO Steve Jobs, who used it to generate audience enthusiasm for a show-closing announcement. [...] Apple flagged the new Mac and macOS releases for a late 2020 release during its all-digital Worldwide Developers Conference in June. macOS 11, also known as Big Sur, is the first Mac operating system to support both Intel CPUs and new "Apple Silicon" processors. These chips have not yet been officially branded, but will rely upon the same ARM instruction sets and comparatively low power consumption designs that have been used in iPhones, iPads, Apple Watches, and Apple TVs for years.

"As promised, SiFive has unveiled a new computer featuring the company's SiFive FU740 processor based on RISC-V architecture," reports Liliputing: The company, which has been making RISC-V chips for several years, is positioning its new SiFive HiFive Unmatched computer as a professional development board for those interested in working with RISC-V. But unlike the company's other HiFive boards, the new Unmatched model is designed so that it can be easily integrated into a standard PC...

SiFive says the system can support GNU/Linux distributions including Yocto, Debian, and Fedora.
"SiFive is releasing the HiFive Unleashed in an effort to afford developers the ability to build RISC-V based systems, using readily available, off-the-shelf parts," explains Forbes: SiFive says it built the board to address the market need for easily accessible RISC-V hardware to further advance development of new platforms, products, and software using the royalty-free ISA...

A short video demo shows the HiFive Unmatched installed in a common mid-tower PC chassis, running the included Linux distro, with an AMD Radeon graphics card pushing the pixels. In the video, the HiFive Unmatched is compiling an application and is shown browsing the web and opening a PDF. SiFive also notes that video playback is accelerated in hardware with the included version of Linux.
"At the moment, these development PCs are early alternatives, most likely targeted at hobbyists and engineers who may snap them up when they become available in the fourth quarter for $665," notes VentureBeat.

But they add that "While it's still early days, it's not inconceivable that RISC-V processors could someday be alternatives to Intel-based PCs and PC processors." The startup has raised $190 million to date, and former Qualcomm executive Patrick Little recently joined SiFive as CEO. His task will be to establish the company's RISC-V processors as an alternative to ARM. This move comes in the wake of Nvidia's $40 billion acquisition of the world's leading processor architecture.

If Little is also looking to challenge Intel and AMD in PCs, he'll have his work cut out for him. For starters, SiFive is currently focused on Linux-based PCs, not Microsoft Windows PCs. Secondly, SiFive wouldn't build these processors or computers on its own. Its customers — anyone brave enough to take on the PC giants — would have to do that.

"I wouldn't see this as SiFive moving out of the box. It's more like they're expanding their box," said Linley Group senior analyst Aakash Jani. "They're using their core architecture to enable other chip designers to build PCs, or whatever they plan to build."

"BDY electronics, a Chinese laptop manufacturer, has unveiled an all-new 13.3-inch laptop sporting Longsoon's new Dragon Core 3A4000 quad-core 14nm CPU," reports Tom's Hardware: The biggest feature of this laptop is the CPU, featuring Longsoon's latest 14nm quad-core 3A4000 CPU. Longsoon claims the CPU is 100% faster than the previous generation 3A3000 and is comparable in performance to AMD's "Excavator" cores used in the A8-7680 Godavari architecture.

Of course, this demonstrates how far behind Longsoon is from TSMC and Intel in performance, speed, and efficiency of its latest node. However, the chairman of Loongsoon Technologies, Hu Weiwu, says, "14nm and 28nm (for its GPU node) is enough for 90% of applications.," so it appears the company isn't too worried about catching up to the performance leaders like Intel and AMD.

Due to this laptop being in the Chinese market, Windows is not supported at all. It only runs Chinese "domestic operating systems" that are typically modified versions of Linux. Fortunately, this does mean you can install any Linux flavor you want on the laptop, which can be handy if you don't want to run China-specific apps only.
Slashdot reader Hmmmmmm points out that Loongson's upcoming 3a5000 CPU "will be a 12nm CPU that is 50% faster than the 3A4000."

In preparation for next year's Xe HPG graphics cards, Intel's open-source developers have begun publishing their patches enabling their "ANC" Vulkan Linux driver to support Vulkan ray-tracing. Phoronix reports: Jason Ekstrand as the lead developer originally on the Intel ANV driver has posted today the initial ray-tracing code for ANV in order to support VK_KHR_ray_tracing for their forthcoming hardware. Today is the first time Intel has approved of this open-source code being published and more is on the way. The code today isn't enough for Vulkan ray-tracing but more is on the way and based against the latest internal Khronos ray-tracing specification. At the moment they are not focusing on the former NVIDIA-specific ray-tracing extension but may handle it in the future if game vendors continue targeting it rather than the forthcoming finalized KHR version.

Among other big ticket items still to come in the near-term includes extending the ANV driver to support compiling and dispatching OpenCL kernels, new SPIR-V capabilities, and generic pointer support. Also needed is the actual support for compiling ray-tracing pipelines, managing acceleration structures, dispatching rays, and the platform support. The actual exposing of the support won't come until after The Khronos Group has firmed up their VK_KHR_ray_tracing extension. Some of this Intel-specific Vulkan ray-tracing code may prove useful to Mesa's Radeon Vulkan "RADV" driver as well. Intel engineers have been testing their latest ray-tracing support with ANV internally on Xe HPG.

An anonymous reader quotes a report from Ars Technica: Researchers have extracted the secret key that encrypts updates to an assortment of Intel CPUs, a feat that could have wide-ranging consequences for the way the chips are used and, possibly, the way they're secured. The key makes it possible to decrypt the microcode updates Intel provides to fix security vulnerabilities and other types of bugs. Having a decrypted copy of an update may allow hackers to reverse engineer it and learn precisely how to exploit the hole it's patching. The key may also allow parties other than Intel -- say a malicious hacker or a hobbyist -- to update chips with their own microcode, although that customized version wouldn't survive a reboot.

"At the moment, it is quite difficult to assess the security impact," independent researcher Maxim Goryachy said in a direct message. "But in any case, this is the first time in the history of Intel processors when you can execute your microcode inside and analyze the updates." Goryachy and two other researchers -- Dmitry Sklyarov and Mark Ermolov, both with security firm Positive Technologies -- worked jointly on the project. The key can be extracted for any chip -- be it a Celeron, Pentium, or Atom -- that's based on Intel's Goldmont architecture. In a statement, Intel officials wrote: "The issue described does not represent security exposure to customers, and we do not rely on obfuscation of information behind red unlock as a security measure. In addition to the INTEL-SA-00086 mitigation, OEMs following Intel's manufacturing guidance have mitigated the OEM specific unlock capabilities required for this research. The private key used to authenticate microcode does not reside in the silicon, and an attacker cannot load an unauthenticated patch on a remote system."

An anonymous reader quotes a report from Network World: The Folding@home project has shared new results of its efforts to simulate proteins from the SARS-CoV-2 virus to better understand how they function and how to stop them. Folding@home is a distributed computing effort that uses small clients to run simulations for biomedical research when users' PCs are idle. The clients operate independently of each other to perform their own unique simulation and send in the results to the F@h servers. In its SARS-CoV-2 simulations, F@h first targeted the spike, the cone-shaped appendages on the surface of the virus consisting of three proteins. The spike must open to attach itself to a human cell to infiltrate and replicate. F@h's mission was to simulate this opening process to gain unique insight into what the open state looks like and find a way to inhibit the connection between the spike and human cells.

And it did so. In a newly published paper, the Folding@home team said it was able to simulate an "unprecedented" 0.1 seconds of the viral proteome. They captured dramatic opening of the spike complex, as well as shape-shifting in other proteins that revealed more than 50 "cryptic" pockets that expand targeting options for the design of antivirals. [...] The model derived from the F@h simulations shows that the spike opens up and exposes buried surfaces. These surfaces are necessary for infecting a human cell and can also be targeted with antibodies or antivirals that bind to the surface to neutralize the virus and prevent it from infecting someone. "And the tech sector played a big role in helping the find," adds the anonymous Slashdot reader. "Microsoft, Nvidia, AMD, Intel, AWS, Oracle, and Cisco all helped with hardware and cloud services. Pure Storage donated a one petabyte all-flash storage array. Linus Tech Tips, a hobbyist YouTube channel for home system builders with 12 million followers, set up a 100TB server to take the load off."

Phoronix ran a story this morning with this provocative headline: "It's Time To Admit It: The X.Org Server Is Abandonware." The last major release of the X.Org Server was in May 2018 but don't expect the long-awaited X.Org Server 1.21 to actually be released anytime soon. This should hardly be surprising but a prominent Intel open-source developer has conceded that the X.Org Server is pretty much "abandonware" with Wayland being the future. [Or, more specifically, that "The main worry I have is that xserver is abandonware without even regular releases from the main branch."]

This comes as X.Org Server development hits a nearly two decade low, the X.Org Server is well off its six month release regimen in not seeing a major release in over two years, and no one is stepping up to manage the 1.21 release. A year ago was a proposal to see new releases driven via continuous integration testing but even that didn't take flight and as we roll into 2021 there isn't any motivation for releasing new versions of the X.Org Server by those capable of doing so.

Red Hat folks have long stepped up to manage X.Org Server releases but with Fedora Workstation using Wayland by default and RHEL working that way, they haven't been eager to devote resources to new X.Org Server releases. Other major stakeholders also have resisted stepping up to ship 1.21 or commit any major resources to new xorg-server versions.

The Python programming language "is a big hit for machine learning," read a headline this week at ZDNet, adding "But now it needs to change."

Python is the top language according to IEEE Spectrum's electrical engineering audience, yet you can't run Python in a browser and you can't easily run it on a smartphone. Plus no one builds games in Python these days. To build browser applications, developers tend to go for JavaScript, Microsoft's type-safety take on it, TypeScript, Google-made Go, or even old but trusty PHP. On mobile, why would application developers use Python when there's Java, Java-compatible Kotlin, Apple's Swift, or Google's Dart? Python doesn't even support compilation to the WebAssembly runtime, a web application standard supported by Mozilla, Microsoft, Google, Apple, Intel, Fastly, RedHat and others.

These are just some of the limitations raised by Armin Ronacher, a developer with a long history in Python who 10 years ago created the popular Flask Python microframework to solve problems he had when writing web applications in Python. Austria-based Ronacher is the director of engineering at US startup Sentry — an open-source project and tech company used by engineering and product teams at GitHub, Atlassian, Reddit and others to monitor user app crashes due to glitches on the frontend, backend or in the mobile app itself... Despite Python's success as a language, Ronacher reckons it's at risk of losing its appeal as a general-purpose programming language and being relegated to a specific domain, such as Wolfram's Mathematica, which has also found a niche in data science and machine learning...

Peter Wang, co-founder and CEO of Anaconda, maker of the popular Anaconda Python distribution for data science, cringes at Python's limitations for building desktop and mobile applications. "It's an embarrassing admission, but it's incredibly awkward to use Python to build and distribute any applications that have actual graphical user interfaces," he tells ZDNet. "On desktops, Python is never the first-class language of the operating system, and it must resort to third-party frameworks like Qt or wxPython." Packaging and redistribution of Python desktop applications are also really difficult, he says.

Intel shares are off around 10% in after-hours trading after the chip company reported its Q3 data. TechCrunch explains why: Investors had expected Intel to report an adjusted $1.11 in per-share profit, off around 22% from the year-ago period. They also expected it to report revenues of $18.26 billion in Q3, down a more modest 5% compared to the year-ago Q3. Notably, Intel beat revenue expectations with top line of $18.3 billion, and met earnings-per-share estimates of $1.11, on an adjusted basis. So, why are Intel shares sharply lower?

Quick consensus appears to point to weakness in the company data-focused business unit, the smaller of Intel's two halves (the other focuses on PC chips). Inside the data-side of Intel, its Data Center Group (DCG) had mixed results, including cloud revenue growth of 15%. However, at the same time, the DCG's "Enterprise & Government" business shrank 47% compared to the year-ago period, following what Intel described as "two quarters of more than 30 percent growth." Off that weakness, the resulting top line miss was sharp, with the market expecting $6.22 billion in revenue and DCG only delivering $5.9 billion.

Intel blamed COVID-19 for the weak economics conditions at play in the result. The company also highlighted COVID-19 when it discussed results from its internet of things business and memory operation, which declined 33% and 11% on a year-over-year basis, respectively. Perhaps due to COVID-19's recent resurgence in both North America and Europe, investors are concerned that the macroeconomic issues harming Intel's growth could continue. If so, growth could be negative for a longer period than anticipated. That perspective could have led to some selling of Intel's equity after the earnings report.

Intel has agreed to sell its Nand memory unit to South Korea's SK Hynix for about $9 billion, a deal that allows the U.S. chipmaker to concentrate on its main business while shoring up the Asian company's position in a booming market. From a report: The chipmaker will pay 10.3 trillion won for the Intel unit, which makes flash memory components for computers and other devices. The acquisition, which will take place in stages through 2025, includes Intel's solid-state drive, Nand flash and wafer businesses, as well as a production facility in the northeastern Chinese city of Dalian. The deal should shore up Hynix's position in a business that's boomed after Covid-19 drove demand for the chips used in everything from Apple's iPhones to data centers. It whittles down another player in an industry the Korean company dominates alongside Samsung Electronics and Micron Technology, potentially buoying Nand flash prices.

The Motley Fool writes: AMD held just under 18% of the CPU market at the end of 2016 before Ryzen arrived. The latest third-party estimates suggest that the chipmaker now controls close to 37% of the market. Other reliable estimates from the likes of video gaming platform Steam also suggest that AMD has been consistently chipping away at Intel's CPU dominance. And AMD isn't done hammering Intel in CPUs just yet — especially since the arrival of its latest Ryzen 5000 CPUs...

According to AMD's own claims, a high-end Ryzen 5000 processor can deliver a 26% jump in gaming performance over the previous-generation chip. AMD also claims that the chip is 7% faster in gaming performance than the competing Intel chip...

Rumors suggest that Intel may not launch its 12th-generation 10nm Alder Lake processors until the second half of 2021 to compete with AMD's 7nm process. So AMD is likely to continue enjoying a technology lead over Intel, especially considering that it could make the move to a 5nm manufacturing process with the Zen 4 microarchitecture by the end of 2021, according to rumors. As such, don't be surprised to see AMD continuing to eat Intel's market share, and remaining a top growth stock in the future thanks to a combination of improved CPU sales and stronger pricing power.

An anonymous reader quotes a report from Ars Technica: Google and Intel are warning of a high-severity Bluetooth flaw in all but the most recent version of the Linux Kernel. While a Google researcher said the bug allows seamless code execution by attackers within Bluetooth range, Intel is characterizing the flaw as providing an escalation of privileges or the disclosure of information. The flaw resides in BlueZ, the software stack that by default implements all Bluetooth core protocols and layers for Linux. Besides Linux laptops, it's used in many consumer or industrial Internet-of-things devices. It works with Linux versions 2.4.6 and later. So far, little is known about BleedingTooth, the name given by Google engineer Andy Nguyen, who said that a blog post will be published "soon." A Twitter thread and a YouTube video provide the most detail and give the impression that the bug provides a reliable way for nearby attackers to execute malicious code of their choice on vulnerable Linux devices that use BlueZ for Bluetooth.

Intel, meanwhile, has issued this bare-bones advisory that categorizes the flaw as privilege-escalation or information-disclosure vulnerability. The advisory assigned a severity score of 8.3 out of a possible 10 to CVE-2020-12351, one of three distinct bugs that comprise BleedingTooth. "Potential security vulnerabilities in BlueZ may allow escalation of privilege or information disclosure," the advisory states. "BlueZ is releasing Linux kernel fixes to address these potential vulnerabilities." Intel, which is a primary contributor to the BlueZ open source project, said that the most effective way to patch the vulnerabilities is to update to Linux kernel version 5.9, which was published on Sunday. Those who can't upgrade to version 5.9 can install a series of kernel patches the advisory links to. Maintainers of BlueZ didn't immediately respond to emails asking for additional details about this vulnerability. Ars Technica points out that since BleedingTooth requires proximity to a vulnerable device, there's not much reason for people to worry about this vulnerability. "It also requires highly specialized knowledge and works on only a tiny fraction of the world's Bluetooth devices," it adds.

Razer has unveiled its fall lineup of gaming products for its base of hardcore gamers, including new laptops and an ergonomic gaming chair. The company unveiled the gear at its first annual RazerCon weekend-long event, a virtual festival filmed at the company's Las Vegas store. The event includes concerts with artists such as Deadmau5, DragonForce and Friends, Sabaton, and Speaker Honey. From a report: More than a million people were watching at the outset of RazerCon as Razer CEO Min-Liang Tan took the stage. He noted that Razer donated more than a million masks during the pandemic and that fans donated 75,000. He said Razer also created a $15 million COVID-19 relief fund and the company is supporting green product design with its products and packaging. Tan also announced a partnership with Conservation International to fund the protection of trees worldwide.

Razer announced the latest version of its Razer Blade Stealth 13 laptop with an "ultrabook" design. It has an 11th Gen Intel Core i7-1165G7 processor running at up to 4.7GHz (base performance of 2.8GHz), a full HD OLED touch display option, and THX Spatial Audio. It also has an Nvidia GeForce GTX 1650 Ti graphics chip (the same as the prior model with 4GB GDDR6 memory, which gives it 10% faster graphics performance) and is 2.7 times better at content creation than the previous version. The display has an option for operating at a 120-hertz refresh rate. Razer marketing manager Eugene Kuo said in a press briefing that the laptop is the company's first to combine the OLED screen with the faster refresh rate. The laptop runs at 28 watts and can produce darker images and contrast ratios. Razer acquired THX, which was founded by filmmaker George Lucas, and is now adding the THX Spatial Audio technology to its peripherals and computers. For gaming, Razer claims the spatial audio offers a competitive edge, as you can hear which direction enemies are coming from. The Razer Blade Stealth 13 will be available this month at $1,800 on Razer.com, as well as through select retailers this fall.

FSGSBASE support in Linux "has the possibility of helping Intel/AMD CPU performance especially in areas like context switching that had been hurt badly by Spectre/Meltdown and other CPU vulnerability mitigations largely on the Intel side," Phoronix wrote back in August. As it started its journey into the kernel, they provided a preview on August 10: The FSGSBASE support that was finally mainlined a few days ago for Linux 5.9 is off to providing a nice performance boost for both Intel and AMD systems... FSGSBASE support for the Linux kernel has been around a half-decade in the making and finally carried over the finish line by one of Microsoft's Linux kernel engineers...

FSGSBASE particularly helps out context switching heavy workloads like I/O and allowing user-space software to write to the x86_64 GSBASE without kernel interaction. That in turn has been of interest to Java and others...On Linux 5.9 where FSGSBASE is finally mainlined, it's enabled by default on supported CPUs. FSGSBASE can be disabled at kernel boot time via the "nofsgsbase" kernel option.
Today on the Linux kernel mailing list, Linus Torvalds announced the release of Linux 5.9: Ok, so I'll be honest - I had hoped for quite a bit fewer changes this last week, but at the same time there doesn't really seem to be anything particularly scary in here. It's just more commits and more lines changed than I would have wished for.
And Phoronix reported: Linux 5.9 has a number of exciting improvements including initial support for upcoming Radeon RX 6000 "RDNA 2" graphics cards, initial Intel Rocket Lake graphics, NVMe zoned namespaces (ZNS) support, various storage improvements, IBM's initial work on POWER10 CPU bring-up, the FSGSBASE instruction is now used, 32-bit x86 Clang build support, and more. See our Linux 5.9 feature overview for the whole scoop on the many changes to see with this kernel.
