Michael Larabel, reporting for Phoronix: This summer AMD announced the Radeon Raytracing Analyzer "RRA" as part of their developer software suite for helping to profile ray-tracing performance/issues on Windows and Linux with both Direct3D 12 and the Vulkan API. Initially the RRA 1.0 release was binary-only but now AMD has made good on their "GPUOpen" approach and made it open-source.

As noted back in my original article from July on the Radeon Raytracing Analyzer release: "Radeon Raytracing Analyzer is hosted on GitHub but the only content in the actual Git repository right now is documentation, so it would appear that at least initially this is a closed-source package though some documentation also says it's MIT licensed."

Last week that was cleared up with the Radeon Raytracing Analyzer source code going public. There are build instructions for compiling the RRA 1.0 sources on both Microsoft Windows and Linux while the Linux instructions are tailoring to Ubuntu use. Building the Radeon Raytracing Analyzer depends upon the Qt 5.15 toolkit.

The Browser Company's Chromium-based Arc browser "isn't perfect, and it takes some getting used to," writes the Verge. "But it's full of big new ideas about how we should interact with the web — and it's right about most of them." Arc wants to be the web's operating system. So it built a bunch of tools that make it easier to control apps and content, turned tabs and bookmarks into something more like an app launcher, and built a few platform-wide apps of its own. The app is much more opinionated and much more complicated than your average browser with its row of same-y tabs at the top of the screen. Another way to think about it is that Arc treats the web the way TikTok treats video: not as a fixed thing for you to consume but as a set of endlessly remixable components for you to pull apart, play with, and use to create something of your own. Want something to look better or have an idea for what to do with it? Go for it.

This is a fun moment in the web browser industry. After more than a decade of total Chrome dominance, users are looking elsewhere for more features, more privacy, and better UI. Vivaldi has some really clever features; SigmaOS is also betting on browsers as operating systems; Brave has smart ideas about privacy; even Edge and Firefox are getting better fast. But Arc is the biggest swing of them all: an attempt to not just improve the browser but reinvent it entirely....

Right now, Arc is only available for the Mac, but the company has said it's also working on Windows and mobile versions, both due next year. It's still in a waitlisted beta and is still very much a beta app, with some basic features missing, other features still in flux, and a few deeply annoying bugs. But Arc's big ideas are the right ones. I don't know if The Browser Company is poised to take on giants and win the next generation of the browser wars, but I'd bet that the future of browsers looks a lot like Arc....

In a way, Arc is more like ChromeOS than Chrome. It tries to expand the browser to become the only app you need because, in a world where all your apps are web apps and all your files are URLs, who really needs more than a browser?
The article describes Arc as a power user tool with vertical sidebar combining bookmarks, tabs, and apps. (And sets of these can apparently be combined into different "spaces".) These are enhanced with a hefty set of keyboard shortcuts (including tab searching), along with built-in media controls for Twitch/Spotify/Google Meet (as well as a picture-in-picture mode).
BR. Arc even has a shareable, collaborative whiteboard app "Easel". And it also offers powerful features like the ability to rewrite how your browser displays any site's CSS. ("I have one that removes the Trending sidebar from Twitter and another that cleans up my Gmail page.")

VMware today announced the launch of Fusion 13, the latest major update to the Fusion virtualization software. MacRumors reports: For those unfamiliar with Fusion, it is designed to allow Mac users to operate virtual machines to run non-macOS operating systems like Windows 11. Fusion 13 Pro and Fusion 13 Player are compatible with both Intel Macs and Apple silicon Macs equipped with M-series chips, offering native support. VMware has been testing Apple silicon support for several months now ahead of the launch of the latest version of Fusion.

With Fusion 13, Intel and Apple silicon Mac users can access Windows 11 virtual machines. Intel Macs offer full support for Windows 11, while on Apple silicon, VMware says there is a first round of features for Windows 11 on Arm. Users who need to run traditional win32 and x64 apps can do so through built-in emulation. Fusion 13 also includes a TPM 2.0 virtual device that can be added to any VM, storing contents in an encrypted section of the virtual machine files and offering hardware-tpm functionality parity. To support this feature, Fusion 13 uses a fast encryption type that encrypts only the parts of the VM necessary to support the TPM device for performance and security. The software supports OpenGL 4.3 in Windows and Linux VMs on Intel and in Linux VMs on Apple silicon.

joshuark writes: Yikes, gadzooks, and shiver my timbers! Elastic Labs has found surprisingly that 50% of malware comes from one app: MacKeeper, ironically. Ironic in that MacKeeper claims to "keep your Mac clean and safe with zero effort." MacKeeper also has a tainted reputation for being difficult to completely uninstall and as a malicious antivirus.

A new spin on the biblical phrase, "Am I my brother's keeper..." Well, when the inmate is running the asylum. The findings appear in Elastic Security Labs' recently released 2022 Global Threat Report. As Neowin reports, MacKeeper "can be abused by threat actors because it has extensive permissions and access to processes and files."

With that said, the report found that only 6.2% of malware ends up on macOS devices, compared to 54.4% and 39.4% on Windows and Linux, respectively.

1Password has announced that passkey support will be available to its customers in "early 2023," allowing users to securely log in to apps and websites without a password. The Verge reports: Passkeys are a passwordless login technology developed by the FIDO Alliance, whose members include most of the Big Tech companies. The tech allows users to replace traditional passwords with their device's own authentication -- such as an iPhone with Face ID -- offering greater security and protection since there's no password to steal or accidentally hand over via a phishing attack.

1Password claims its own variation, called Universal Sign On, will be superior to others by supporting multiple platforms and cross-platform syncing when it launches next year. By contrast, passkey support through companies like Apple is only built to seamlessly synchronize access on devices within the same ecosystem. A live demonstration of how passkeys will work is available for 1Password users using the latest version of its Chrome browser extension, alongside a video demo for those not using the service and a directory listing which websites, apps, and services are using passkeys for authentication. 1Password will bring full support for passkeys to its browser extension and desktop apps in early 2023, with mobile support to follow.

Microsoft has fixed yet another problem in some versions of Windows 10, a bug that makes the taskbar and desktop temporarily vanish or causes the system to ignore you. From a report: According to Redmond, users "might experience an error in which the desktop or taskbar might momentarily disappear, or your device might become unresponsive." The issue affects PCs running Windows 10 versions 22H2, 21H2, 21H1, and 20H2, the company wrote on its Windows Health Dashboard. Microsoft didn't outline the exact cause but notes it was related to the KB5016688 220820_03051 cumulative update and later.

The software giant is using its Known Issue Rollback (KIR) feature -- which enables IT administrators to roll back the unwanted changes of an update -- to resolve the problem, adding that it could take up to 24 hours for the fix to reach non-managed business systems and consumer devices. Restarting the device may accelerate the timeframe. Organizations that use enterprise-managed devices can install and configure a special Group Policy by going to "Computer Configuration" and then "Administrative Templates" and "Group Policy name." If the resolution doesn't work, users can try restarting the Windows device, according to Microsoft. The latest fix comes after a number of other problems were resolved this week.

Waymo's latest car sensor arrays are "creating real-time weather maps to improve ride hailing services in Phoenix and San Francisco," reports Engadget. "The vehicles measure the raindrops on windows to detect the intensity of conditions like fog or rain." From the report: The technology gives Waymo a much finer-grained view of conditions than it gets from airport weather stations, radar and satellites. It can track the coastal fog as it rolls inland, or drizzle that radar would normally miss. While that's not as important in a dry locale like Phoenix, it can be vital in San Francisco and other cities where the weather can vary wildly between neighborhoods. There are a number of practical advantages to gathering this data, as you might guess. Waymo is using the info to improve its Driver AI's ability to handle rough weather, including more realistic simulations. The company also believes it can better understand the limits of its cars and set higher requirements for new self-driving systems. The tech also helps Waymo One better serve ride hailing passengers at a given time and place, and gives Waymo Via trucking customers more accurate delivery updates.

The current weather maps have their limitations. They may help in a warm city like San Francisco, where condensation and puddles are usually the greatest problems, but they won't be as useful for navigating snowy climates where merely seeing the lanes can be a challenge. There's also the question of whether or not it's ideal to have cars measure the very conditions that hamper their driving. This isn't necessarily the safest approach. Waymo describes the research in a blog post.

Microsoft has started testing a new search and filtering system for the Task Manager on Windows 11. It will allow Windows users to easily search for a misbehaving app and end its process or quickly create a dump file, enable efficiency mode, and more. From a report: "This is the top feature request from our users to filter / search for processes," explains the Windows Insider team in a blog post. "You can filter either using the binary name, PID or publisher name. The filter algorithm matches the context keyword with all possible matches and displays them on the current page." You'll be able to use the alt + F keyboard shortcut to jump to the filter box in the Task Manager, and results will be filtered into single or groups of processes that you can monitor or take action on. Alongside the new search and filter functionality, Microsoft is also adding the ability to pick between light or dark themes in the Task Manager. Themes will also be applied fully throughout Task Manager, with some updates to its UI to fit more closely with Microsoft's overall Fluent work.

Microsoft is releasing DirectStorage 1.1 this week, and the biggest new addition is GPU decompression for Windows PC games. The Verge reports: GPU decompression works by offloading the work needed to decompress assets in games to the graphics card instead of the CPU. Right now, game assets are typically compressed when they are packaged up for distribution and then decompressed once a game is played. The problem is most compression techniques are designed for CPUs, which aren't great for modern games that want to push for faster decompression rates with the latest PC hardware.

We've seen the industry move to PCIe Gen3 or Gen4 NVMe storage devices in recent years, offering 7GB/s of data bandwidth. This fast storage is great news for game developers wanting to speed up load times, and the advances in I/O technology can dramatically speed up load times and games using DirectStorage 1.1. Developers will now need to tweak their games to make use of DirectStorage 1.1, and the improvements could even see big changes inside games where you move from one world to another or teleport between different parts of a map or world. Microsoft claims this can be as much as three times faster, freeing up the CPU to handle other game processes. [...] All we need now is game support.

Google is bringing its VPN access to desktop today. Google One subscribers on Premium plans (2TB or higher) can now download VPN apps for Windows and macOS, allowing users in 22 countries to mask their IPs on desktop and reduce online trackers. From a report: While Google is expanding its VPN service, it still comes with the same restrictions as Android and iOS. You'll only be able to use the service in one of the supported countries, and you won't be able to use Google's VPN freely to avoid geo-restrictions on live sports or other streaming video. Much like Apple's iCloud Plus VPN service, the Google One VPN won't let you assign an IP address from a different country manually. Instead, Google assigns you an IP in the region you're connecting from.

Microsoft is now promoting some of its products in the sign-out flyout menu that shows up when clicking the user icon in the Windows 11 start menu. BleepingComputer: This new Windows 11 "feature" was discovered by Windows enthusiast Albacore, who shared several screenshots of advertisement notifications in the Accounts flyout. The screenshots show that Microsoft promotes the OneDrive file hosting service and prods users to create or complete their Microsoft accounts.

Those reacting to this on social media had an adverse reaction to Redmond's decision to display promotional messages in the start menu. Some said that Windows 11 is "getting worse in each and every update it gets," while others added that this is a weird choice given that "half of the Start Menu is for recommendations" anyway. BleepingComputer has also tried replicating this on multiple Windows 11 systems, but we didn't get any ads. This hints at an A/B testing experiment trying to gauge the success of such a "feature" on devices running Windows Insider builds or the company pushing such ads to a limited set of customers.

A new survey on the Xbox Insider Hub suggests Microsoft is looking to expand on its energy saving features for Xbox consoles and potentially PC games too. Jez Corden writes via Windows Central: A recent questionnaire I came across in the Xbox Insider app on Windows PC detailed a potential list of new features Microsoft is exploring for games across consoles and PC. These new features pertain specifically to opting-in to reduce frame rates, resolution, and so on, with the goal of limiting energy consumption. Of course, surveys don't necessarily mean that these sorts of features will make it into a final product, but Microsoft's commitments to net zero carbon use have seen the firm increase its investments in this space.

The survey asks users about their current feelings with regard to energy consumption, potentially polling users on how the energy crisis is affecting their willingness to spend. The survey asks users if they would be interested in features that reduce power consumption in games, both while the games are running and while they're inactive, specifically to save energy and thus money. Microsoft also asks users how they would prefer these features to be branded, with terms like "eco-saving" and "energy-saving," and even asks if these sorts of features would affect users' purchase decisions per game.

The Register: A number of job postings -- including this now-closed ad from late September for a principal software engineering manager -- are looking for engineers and others to become part of the "newly formed Windows Incubation team" whose mission is to "build a new direction for Windows in a cloud first world."

The lofty goal is to "move Windows to a place that combines the benefits of the cloud and Microsoft 365 to offer more compute resources on demand and creates a hybrid app model that spans from on-premises to the cloud." According to the ad, it also includes "building a Web-based shell with direct integration with Windows 365." Included in the possible models are low-cost PCs available via subscriptions, with advertising helping to offset some of the costs. (Also mentioned in the job are direct-to-cloud devices.)

Much of the Windows world has yet to adopt Microsoft's latest desktop operating system more than a year after it launched, according to figures for October collated by Statcounter. From a report: Just 15.44 percent of PCs across the globe have installed Windows 11, meaning it gained 1.83 percentage points in a month. This compares to the 71.29 percent running Windows 10, which fell marginally from 71.88 percent in September. Windows 7 is still hanging on with a tenuous grip, in third place with 9.61 percent, Windows 8.1 in fourth with 2.45 percent, plain old Windows 8 with 0.69 percent, and bless its heart, Windows XP with 0.39 percent because of your extended family. In total, Windows has almost 76 percent of the global desktop OS market followed by OS X with 15.7 percent and Linux with 2.6 percent. Android comprised 42.37 percent of total operating system market share, with Windows trailing on 30.11 percent, iOS on 17.6 percent, OS X on 6.24 percent, and Linux on 1.04 percent.

An anonymous reader quotes a report from The Verge: Darin Fisher has built a lot of web browsers. A lot of web browsers. He was a software engineer at Netscape early in his career, working on Navigator and then helping turn that app into Firefox with Mozilla. Then, he went to Google and spent 16 years building Chrome and ChromeOS into massively successful products. Last year, he left Google for Neeva, where he worked on ways to build a browser around the startup's search engine. And now, he's leaving Neeva to join The Browser Company and work on Arc, one of the hottest new browsers on the market. Arc, which has been in an invite-only beta for more than a year, is trying to rethink the whole browser UI. It has a sidebar instead of a row of tabs, offers a lot of personalization options, and is meant for people who live their computing life in a browser (which is increasingly most people). CEO Josh Miller often talks about building "the internet computer," too, and using the browser as a way to make the internet more useful.

Fisher has been an advisor to The Browser Company for a while, but Monday is his first official day at the company as a software engineer. Ahead of his new gig, Fisher and I got on a call to talk about why he thinks browsers are due for a reinvention -- and why he thinks a startup is the best place to do it. The answer starts with the browser's defining feature: tabs. Fisher doesn't hate tabs -- in fact, he helped popularize them. But he hates that using a modern browser involves opening a million of them, not being able to find them again, and eventually just giving up and starting all over again. "I remember when tabbed browsing was novel," Fisher says, "and helped people feel less cluttered because you don't have as many windows." But now, "even when I use Chrome," Fisher says, "I get a bunch of clutter. At some point, I just say, 'Forget it, I'm not even going to bother trying to sort through all these tabs. If it's important, I'll open it again.'" Browsers need better systems for helping you manage tabs, not just open more of them.

The best way to improve the browser, Fisher ultimately decided, is to just start from scratch. Arc is full of new ideas about how web browsers can work: it combines bookmarks and tabs into one app switcher-like concept; it makes it easy to search among your open tabs; it has built-in tools for taking notes and making shareable mini websites. The experience can be jarring because it's so different, but Fisher says that's part of what he's excited about. "This is not stuff people haven't talked about before," he says, "but actually putting it together and focusing on it and thinking about the small steps that go a long way, I think that's where there's so much opportunity." Fisher likes to compare a browser to an operating system, which matches with The Browser Company's idea that Arc isn't just a browser but rather an iOS-like system for the open web. "It has task management UI, it has UI for creating and starting a journey, but there's so much more in between," he says. What the iPhone did for native apps, Arc hopes to do for web apps. Fisher says he's interested in improving the way files move around the internet, for instance, finding a better way than the constant downloading and uploading we all do all day. He likes that Arc has a picture-in-picture mode that works by default, pulling your YouTube video out when you switch tabs. All these make the web feel more connected and cohesive rather than just a bunch of tabs in a horizontal line. The Browser Company also plans to reinvent the internet browser for mobile, too. On mobile, in particular, he says, "there are so many opportunities because the starting point is so archaic."

"He's vague on the details of his plans -- and The Browser Company hasn't really started working on a mobile browser yet anyway -- but says that's a big focus for him going forward," adds The Verge.

Microsoft Corporate Vice President Joe Belfiore will leave Microsoft after 32 years with the company. From a report: Belfiore has served in several roles at Microsoft but is currently the CVP of Office. His plans to retire were announced internally in an email sent out to employees and later shared publicly on Twitter. Belfiore will be a senior advisor and coach to aid the transition until summer 2023. The Office Group will be led by CVP Ales Holecek, who has led the division alongside Belfiore for several years, and CVP Sumit Chauhan, who will move up from their role as head of Office Organization. Many of our readers know Belfiore best for his time in charge of Windows Phone. He co-led that division from 2009 to 2013, which included Microsoft's acquisition of Nokia. Belfiore then went on to lead the Windows 10 team for almost five years.

An anonymous reader quotes a report from ZDNet: Everyone depends on OpenSSL. You may not know it, but OpenSSL is what makes it possible to use secure Transport Layer Security (TLS) on Linux, Unix, Windows, and many other operating systems. It's also what is used to lock down pretty much every secure communications and networking application and device out there. So we should all be concerned that Mark Cox, a Red Hat Distinguished Software Engineer and the Apache Software Foundation (ASF)'s VP of Security, this week tweeted, "OpenSSL 3.0.7 update to fix Critical CVE out next Tuesday 1300-1700UTC." How bad is "Critical"? According to OpenSSL, an issue of critical severity affects common configurations and is also likely exploitable. It's likely to be abused to disclose server memory contents, and potentially reveal user details, and could be easily exploited remotely to compromise server private keys or execute code execute remotely. In other words, pretty much everything you don't want happening on your production systems.

The last time OpenSSL had a kick in its security teeth like this one was in 2016. That vulnerability could be used to crash and take over systems. Even years after it arrived, security company Check Point estimated it affected over 42% of organizations. This one could be worse. We can only hope it's not as bad as that all-time champion of OpenSSL's security holes, 2014's HeartBleed. [...] There is another little silver lining in this dark cloud. This new hole only affects OpenSSL versions 3.0.0 through 3.0.6. So, older operating systems and devices are likely to avoid these problems. For example, Red Hat Enterprise Linux (RHEL) 8.x and earlier and Ubuntu 20.04 won't be smacked by it. RHEL 9.x and Ubuntu 22.04, however, are a different story. They do use OpenSSL 3.x. [...] But, if you're using anything with OpenSSL 3.x in -- anything -- get ready to patch on Tuesday. This is likely to be a bad security hole, and exploits will soon follow. You'll want to make your systems safe as soon as possible.

Do you have a laptop that's either "pretty old" or "weird in some other way"? Did it ship without Windows from the factory, or did you flash its firmware with coreboot? You could help the Linux kernel move its backlight code forward without abandoning quirky gear like yours. ArsTechnica: Hans de Goede, a longtime Linux developer and principal engineer at Red Hat, writes on his Livejournal about the need to test "a special group of laptops" to prevent their backlight controls from disappearing in Linux kernel 6.1. Old laptop tests are needed because de Goede is initiating some major changes to user-space backlight controls, something he has been working on since 2014. As detailed at Linux blog Phoronix, there are multiple issues with how Linux tries to address the wide variety of backlight schemes in displays, which de Goede laid out at the recent Linux Plumbers Conference. There can be multiple backlight devices operating a single display, leaving high-level controls to "guess which one will work." Brightness control requires root permissions at the moment. And "0" passed along as a backlight value remains a conundrum, as the engineer pointed out in 2014: Is that entirely off, or as low as the display can be lit?

An anonymous reader shares a report: Microsoft is still struggling to learn what exactly it takes to be a successful Android manufactuer. The company's first self-branded Android phones, the dual-screened Surface Duo and Surface Duo 2, have tried to resurrect Microsoft's mobile ambitions after the death of Windows Phone. They leave a lot to be desired, though, and the first version went through some embarrassing fire sales. An ongoing knock against the devices has also been Microsoft's very slow OS updates. Unlike, say, Windows and Windows Update, Google's expensive and labor-intensive Android update process puts the responsibility for updates on the hardware seller, and a big part of being a good Android OEM is how quickly you can navigate this complicated process. Microsoft is proving to not be good at this.

This week, Microsoft announced the Surface Duo and Surface Duo 2 are finally getting Android 12L, an OS update that came out in March. That puts that company at a more than seven-month update time, which is worst-in-class for a flagship device, especially for one costing the $1,499 Microsoft is charging for the Duo 2. The company took a prolonged 14 months to ship Android 11 to the Surface Duo, so at least it's improving!

Chrome will no longer support Windows 7 nor Windows 8.1 upon the release of Chrome 110, currently scheduled to hit stable on February 7, 2023. From that point on, you'll need to be running at least Windows 10 to maintain access to new builds. Android Police reports: While Google won't be doing anything to stop users of older platforms from continuing to install and run earlier releases of Chrome, they'd be missing out on the latest critical security and usability enhancements.
