Millions of Emails meant for US Military Recipients Have Been Going To Mali
by Lawrence D'Oliveiro 18 Jul '23

18 Jul '23

Seems like, for the last decade, way too many emails meant for .mil addresses have been going to .ml instead <https://www.theregister.com/2023/07/18/us_military_mali_email_typos/>. The guy who runs the .ml DNS registry for the Mali Government has been trying to notify the offenders about their mistakes, with limited success. It seems to me an obvious solution is to stop using that top-level .mil, and change it to something like .mil.us instead.

Is Wayland Becoming the Favored Way to Get a GUI on Linux?
by Peter Reutemann 18 Jul '23

18 Jul '23

'The Register shares its collection of "signs that Wayland is becoming the favored way to get a GUI on Linux." - The team developing Linux for Apple Silicon Macs said they didn't have the manpower to work on X.org support. - A year ago, the developers of the Gtk toolkit used by many Linux apps and desktops said that the next version may drop support for X11... - One of the developers of the Budgie desktop, Campbell Jones, recently published a blog post with a wildly controversial title that made The Reg FOSS desk smile: "Wayland is pretty good, actually." He lays out various benefits that Wayland brings to developers, and concludes: "Primarily, what I've learned is that Wayland is actually really well-designed. The writing is on the wall for X, and Wayland really is the future." Partly as a result of this, it looks likely that the next version of the Budgie desktop, Budgie 11, will only support Wayland, completely dropping support for X11. The team point out that this is not such a radical proposition: there was a proposal to make KDE 6 sessions default to Wayland as long ago as last October... - The GNOME spin of Fedora has defaulted to Wayland since version 25 in 2017, and the GNOME flavor of Ubuntu since 21.04. - [T]here's now an experimental effort to get Wayland working on OpenBSD. The effort happened at the recent OpenBSD hackathon in Tallinn, Estonia, and the developer's comments are encouraging. It's already available as part of FreeBSD.' -- source: https://linux.slashdot.org/story/23/07/17/0159246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

WordPress plugin installed on 1 million+ sites logged plaintext passwords
by Peter Reutemann 17 Jul '23

17 Jul '23

'All-In-One Security, a WordPress security plugin installed on more than 1 million websites, has issued a security update after being caught three weeks ago logging plaintext passwords and storing them in a database accessible to website admins. The passwords were logged when users of a site using the plugin, typically abbreviated as AIOS, logged in, the developer of AIOS said Thursday. The developer said the logging was the result of a bug introduced in May in version 5.1.9. Version 5.2.0 released Thursday fixes the bug and also “deletes the problematic data from the database.” The database was available to people with administrative access to the website.' -- source: https://arstechnica.com/security/2023/07/wordpress-plugin-installed-on-1-mi… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

AlmaLinux No Longer Aims For 1:1 Compatibility With RHEL
by Peter Reutemann 17 Jul '23

17 Jul '23

'Phoronix: With Red Hat now restricting access to the RHEL source repositories, AlmaLinux and other downstreams that have long provided "community" rebuilds of Red Hat Enterprise Linux with 1:1 compatibility to upstream RHEL have been left sorting out what to do. Benny Vasquez, Chair of the Board for the AlmaLinux OS Foundation, wrote in a blog post yesterday: After much discussion, the AlmaLinux OS Foundation board today has decided to drop the aim to be 1:1 with RHEL. AlmaLinux OS will instead aim to be Application Binary Interface (ABI) compatible*. We will continue to aim to produce an enterprise-grade, long-term distribution of Linux that is aligned and ABI compatible with RHEL in response to our community's needs, to the extent it is possible to do, and such that software that runs on RHEL will run the same on AlmaLinux. For a typical user, this will mean very little change in your use of AlmaLinux. Red Hat-compatible applications will still be able to run on AlmaLinux OS, and your installs of AlmaLinux will continue to receive timely security updates. The most remarkable potential impact of the change is that we will no longer be held to the line of "bug-for-bug compatibility" with Red Hat, and that means that we can now accept bug fixes outside of Red Hat's release cycle. While that means some AlmaLinux OS users may encounter bugs that are not in Red Hat, we may also accept patches for bugs that have not yet been accepted upstream, or shipped downstream."

When Open Becomes Opaque: the Changing Face of Open-Source Hardware Companies
by Peter Reutemann 17 Jul '23

17 Jul '23

'A thoughtful post on the Adafruit Blog chronicles the problems facing open-source hardware companies, and how more and more companies, including Sparkfun, Arduino and Prusa, are becoming more and more proprietary. In Arduino's case, they are deliberately trying to stamp out the clones undercutting them. The new Arduino Pro is not open source in any way, and the web site has now removed references to being an open source company. As always there are subtleties and nuances. In the case of Prusa, not only are Chinese companies taking Prusa designs and source to make proprietary, closed-source products, they are also actively patenting designs and algorithms they've taken from open source. The original submission ends with a question. "With Red Hat recently taking a step towards becoming a proprietary software company (which happens to use and work on open source projects) and now these reports, what are Slashdotters' thoughts on the future? "Are truly open source companies doomed to failure, especially when overseas companies do not respect or even understand the principles of open source development?"' -- source: https://news.slashdot.org/story/23/07/15/1853247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Speed Versus Bandwidth
by Lawrence D'Oliveiro 16 Jul '23

16 Jul '23

Love the (original) opening sentence of this article <https://arstechnica.com/gadgets/2023/07/light-based-lifi-promises-amazing-w…>: Light is almost certainly the fastest thing around. So it makes sense that "light-based wireless communications," or LiFi, could blow the theoretical doors off existing radio-wave wireless standards, to the tune of a maximum 224GB per second. A correction/clarification immediately follows, but it’s clear the writer didn’t quite grasp that both visible light and radio waves are propagated by exactly the same particles--photons--travelling at exactly the same speed. What is true is that, as the frequency of the photons increases, so does their information-carrying capacity. This is why we have digital broadcasts (TV particularly), mobile phone/data services and our own wi-fi networks all moving to higher and higher frequencies. The downside is, as the frequency of a photon increases, so does its energy. And so it tends to react more and more with (i.e. be absorbed by) various bits of matter that it might encounter--such as the walls of buildings, or even the air itself. This tends to limit the useful range of these communication bands.

Torvalds Calls For Calm as Bcachefs Filesystem Doesn't Make Linux 6.5
by Peter Reutemann 11 Jul '23

11 Jul '23

'Linus Torvalds has delivered the first release candidate for version 6.5 of the Linux kernel, but warned this release may not go entirely smoothly. From a report: Torvalds's headline assessment of rc1 is "none of it looks hugely unusual." "The biggest single mention probably goes to what wasn't merged, with the bcachefs pull request resulting in a long thread (we didn't hit a hundred emails yet, but it's not far away)." As The Register reported in 2022, bcachefs is a filesystem that's been in development for nigh on a decade without being added to the kernel. Kernel-watching outlet Phoronix on Sunday wrote that the filesystem is in good shape but debate over "code changes needed to the kernel outside of the kernel module itself" have proved contentious. As a result, conversation on the Linux kernel mailing list is "often becoming heated" when the topic turns to bcachefs. In his announcement post for rc1, Torvalds wrote "Let's calm this party down."' -- source: https://linux.slashdot.org/story/23/07/10/2042253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Fairphone 3 Gets Seven Years of Updates, Besting Every Other Android OEM
by Peter Reutemann 11 Jul '23

11 Jul '23

'Ars Technica: No one in the Android ecosystem can hold a candle to Apple's software support timeline for the iPhone, but there is one company that comes the closest: Fairphone. Following in the footsteps of the Fairphone 2, the Fairphone 3 is also getting an Android-industry-best seven years of OS support. Fairphone continues to run circles around giant tech companies that have a lot more resources than it does, and it's doing this even in the face of component vendors like Qualcomm dropping support for the phone's core components. The company announced today that the Fairphone 3, which was released in 2019, has had its support extended to 2026, making for seven years of updates. The company also just released Android 13 for the Fairphone 3. Google's own 2019 phone, the Pixel 4, shut down support in October 2022. Fairphone strives to make sustainable smartphones, designing its products to be repairable and also offering replacement parts for sale online. Part of that sustainability mission is an absolutely herculean effort to keep the Android updates flowing, even when Qualcomm drops critical software support for the SoC. Fairphone says the Snapdragon 632 SoC in the Fairphone 3 was only supported up to Android 11, so continuing to support the Fairphone 3 meant doing the upgrades all by itself.' -- source: https://tech.slashdot.org/story/23/07/10/213256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mastodon fixes critical “TootRoot” vulnerability allowing node hijacking
by Peter Reutemann 10 Jul '23

10 Jul '23

'The maintainers of the open source software that powers the Mastodon social network published a security update on Thursday that patches a critical vulnerability making it possible for hackers to backdoor the servers that push content to individual users. Mastodon is based on a federated model. The federation comprises thousands of separate servers known as "instances." Individual users create an account with one of the instances, which in turn exchange content to and from users of other instances. To date, Mastodon has more than 12,000 instances and 14.5 million users, according to fedidb.org/, a site that tracks statistics related to Mastodon. A critical bug tracked as CVE-2023-36460 was one of two vulnerabilities rated as critical that were fixed on Thursday. In all, Mastodon on Thursday patched five vulnerabilities. So far, Mastodon gGmbH, the nonprofit that maintains the software instances uses to operate the social network, has released few details about CVE-2023-36460 other than to describe it as an “arbitrary file creation through media attachments” flaw. “Using carefully crafted media files, attackers can cause Mastodon's media processing code to create arbitrary files at any location," Mastodon said. "This allows attackers to create and overwrite any file Mastodon has access to, allowing Denial of Service and arbitrary Remote Code Execution.” In a Mastodon post, independent security researcher Kevin Beaumont went a step further, writing that exploiting the vulnerability allowed someone “to send a toot which makes a webshell on instances that process said toot.” He coined the name #TootRoot because user posts, known as toots, allowed hackers to potentially gain root access to instances.' -- source: https://arstechnica.com/security/2023/07/mastodon-fixes-critical-tootroot-v… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers Discovered a New Linux Kernel 'StackRot' Privilege Escalation Vulnerability
by Peter Reutemann 10 Jul '23

10 Jul '23

'Wednesday Greg Kroah-Hartman announced the release of the 6.4.2 kernel. "All users of the 6.4 kernel series must upgrade." The Hacker News reports: Details have emerged about a newly identified security flaw in the Linux kernel that could allow a user to gain elevated privileges on a target host. Dubbed StackRot (CVE-2023-3269, CVSS score: 7.8), the flaw impacts Linux versions 6.1 through 6.4. There is no evidence that the shortcoming has been exploited in the wild to date. "As StackRot is a Linux kernel vulnerability found in the memory management subsystem, it affects almost all kernel configurations and requires minimal capabilities to trigger," Peking University security researcher Ruihan Li said. "However, it should be noted that maple nodes are freed using RCU callbacks, delaying the actual memory deallocation until after the RCU grace period. Consequently, exploiting this vulnerability is considered challenging." Following responsible disclosure on June 15, 2023, it has been addressed in stable versions 6.1.37, 6.3.11, and 6.4.1 as of July 1, 2023, after a two-week effort led by Linus Torvalds. A proof-of-concept (PoC) exploit and additional technical specifics about the bug are expected to be made public by the end of the month. ZDNet points out that Linux 6.4 "offers improved hardware enablement for ARM boards" and does a better job with the power demands of Steam Deck gaming devices. And "On the software side, the Linux 6.4 release includes more upstreamed Rust code. We're getting ever closer to full in-kernel Rust language support." The Register also notes that Linux 6.4 also includes "the beginnings of support for Apple's M2 processors," along with support for hibernation of RISC-V CPUs, "a likely presage to such silicon powering laptop computers."' -- source: https://linux.slashdot.org/story/23/07/09/0131210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Undocumented Raspberry Pi
by Lawrence D'Oliveiro 10 Jul '23

10 Jul '23

This little project <https://github.com/cariboulabs/cariboulite> for an SDR (Software-Defined Radio) addon card for a Raspberry Pi popped up on my feed. What caught my eye was that it made use of something called “SMI” (the “Secondary Memory Interface”) which exists on the GPIO connector but is not properly documented. There is a link to this blog post <https://iosoft.blog/2020/07/16/raspberry-pi-smi/> in which the writer reports some investigations into the details of this interface. Speed tests in that article give results of 25 16-bit samples per second or more, depending on the Raspberry Pi model; though note there are some odd glitches sometimes, as well as high bus contention (clearly pushing the Pi hardware to its limits). Maybe this is why the interface is not documented: because it is not considered production-ready ...

AMD CPU Use Among Linux Gamers Approaching 70% Marketshare
by Peter Reutemann 05 Jul '23

05 Jul '23

'The June Steam Survey results show that AMD CPUs have gained significant popularity among Linux gamers, with a market share of 67% -- a remarkable 7% increase from the previous month. Phoronix reports: In part that's due to the Steam Deck being powered by an AMD SoC but it's been a trend building for some time of AMD's increasing Ryzen CPU popularity among Linux users to their open-source driver work and continuing to build more good will with the community. In comparison, last June the AMD CPU Linux gaming marketshare came in at 45% while Intel was at 54%. Or at the start of 2023, AMD CPUs were at a 55% marketshare among Linux gamers. Or if going back six years, AMD CPU use among Linux gamers was a mere 18% during the early Ryzen days. It's also the direct opposite on the Windows side. When looking at the Steam Survey results for June limited to Windows, there Intel has a 68% marketshare to AMD at 32%. Beyond the Steam Deck, it's looking like AMD's efforts around open-source drivers, AMD expanding their Linux client (Ryzen) development efforts over the past two years, promises around OpenSIL, and other efforts commonly covered on Phoronix are paying off for AMD in wooing over their Linux gaming customer base.' -- source: https://hardware.slashdot.org/story/23/07/03/2233208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 115 Released
by Peter Reutemann 05 Jul '23

'Today, Mozilla released Firefox 115. Changes most visible to users include: * Hardware video decoding is now enabled for Intel GPUs on Linux.. * Migrating from another browser? Now you can bring over payment methods you've saved in Chrome-based browsers to Firefox. * The Tab Manager dropdown now features close buttons, so you can close tabs more quickly. * The Firefox for Android address bar's new search button allows you to easily switch between search engines and search your bookmarks and browsing history. * We've refreshed and streamlined the user interface for importing data in from other browsers. * Users without platform support for H264 video decoding can now fallback to Cisco's OpenH264 plugin for playback. But the most important feature is that this release is the new ESR. Why this is important? y'all ask, well: * Many a "downstream" project depends on Firefox ESR, for example the famous email client Thunderbird, or KaiOS (a mobile OS very popular in India, SE Asia, Africa and LatAm), so, for better or worse, whatever made it to (or is lacking from) this version of the browser, those projects have to use for the next year. * Firefox ESR is the default browser of many distros, like Debian and Kali Linux, so, whatever made it to this version will be there for next year, ditto to whatever is lacking. * If you are on old -- unsupported OSs, like Windows 7, 8-8.1 or MacOS 10.14 (Mojave, the last MacOS with support for 32 Bit Apps), 10.13 or 10.12 you will automatically be migrated to Firefox ESR, so this will be your browser until Sept. 2024.' -- source: https://news.slashdot.org/story/23/07/04/189258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Comprehensive Analysis of the GPL Issues With the Red Hat Enterprise Linux (RHEL) Business Mode
by Peter Reutemann 30 Jun '23

30 Jun '23

'For approximately twenty years, Red Hat (now a fully owned subsidiary of IBM) has experimented with building a business model for operating system deployment and distribution that looks, feels, and acts like a proprietary one, but nonetheless complies with the GPL and other standard copyleft terms. Software rights activists, including SFC, have spent decades talking to Red Hat and its attorneys about how the Red Hat Enterprise Linux (RHEL) business model courts disaster and is actively unfriendly to community-oriented Free and Open Source Software (FOSS). These pleadings, discussions, and encouragements have, as far as we can tell, been heard and seriously listened to by key members of Red Hat's legal and OSPO departments, and even by key C-level executives, but they have ultimately been rejected and ignored — sometimes even with a “fine, then sue us for GPL violations” attitude. Activists have found this discussion frustrating, but kept the nature and tenure of these discussions as an “open secret” until now because we all had hoped that Red Hat's behavior would improve. Recent events show that the behavior has simply gotten worse, and is likely to get even worse.' -- source: https://sfconservancy.org/blog/2023/jun/23/rhel-gpl-analysis/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Potted History Of 60 Years Of Computer Networking
by Lawrence D'Oliveiro 29 Jun '23

29 Jun '23

These guys, Larry Peterson and Bruce Davie, have done a whole series of open-source books all around the common theme of “A Systems Approach”. Here <https://www.theregister.com/2023/06/28/60_years_of_networking/> one of them offers a summary of the origins of the Internet, going back to the invention of packet switching and “best effort” delivery, and how that turned out to be such an important change from the traditional telephone network. He also takes the credit/blame for a long-standing myth about the Internet: I feel obligated to point out that there is no mention in this paper of the internet being designed to withstand nuclear attack. Unfortunately, I was responsible for perpetuating that misconception in an early edition of Computer Networks: A Systems Approach. Leiner et al debunk this myth and explain its origins in their paper, but it’s a remarkably persistent one. “[C]ontinue despite loss of networks or gateways” is as close as it gets. But now, cracks are starting to show in the trend toward centralization of popular Internet services. Not only is the “Fediverse” providing alternatives to Twitter and Facebook, but it is now also offering choices to those fed up with recent developments at Reddit, as well.

The ReactOS Project Suddenly Shows Signs of Life
by Peter Reutemann 29 Jun '23

29 Jun '23

'ReactOS is an open-source operating system that aims to replicate Microsoft Windows, and can already run many Windows applications without modification. ReactOS published a new (infrequent) newsletter to outline recent work. It reveals that progress has slowed down recently, but the project definitely isn't dead. The newsletter also acknowledges the team hasn't put out a new version since the end of 2021, although progress continues. Due to shifting focuses to quality releases, they are no longer on a quarterly release cadence. The date of the next release is not set yet, but according to a huge list of already-implemented changes they aim for it to be a substantial update. The last update to ReactOS was version 0.4.14, released on December 2021. While developers were previously committed to releasing updates every three months, that has since changed and updates will now be focused on quality rather than quantity. For the ReactOS team to be confident enough to release something, it needs to have less than 20 known unfixed regressions while adding new features and functions. Behind the scenes, it looks like things are spinning well. The team specifically highlighted its progress on the x64 port of ReactOS, which went from being a non-booting mess to an operating system that boots up and mostly works. It doesn't run any x86 programs since it doesn't have WoW64, but it's going well.' -- source: https://tech.slashdot.org/story/23/06/28/212238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft's GitHub Under Fire For DDoSing Crucial Open Source Project Website
by Peter Reutemann 29 Jun '23

29 Jun '23

'The servers used by the GMP project, an open source arithmetic library at the heart of GCC and other programs, slowed to a crawl earlier this month due to a large amount of network traffic originating from Microsoft servers. The Register reports: Torbjorn Granlund, principal author of GMP, raised the alarm in a note to the project's mailing list. "The GMP servers are under attack by several hundred IP addresses owned by Microsoft Corporation," he wrote. "We do not know if this is made with malice by Microsoft, if it is some sort of mistake, or if [it is one] of their cloud customers ... running the attack. The attack targets the GMP repo, with thousands of identical requests. The requests are cleverly chosen as to cause heavy system load. "We're firewalling off all of Microsoft's IP addresses as an emergency response." The following day, Mike Blacker, director of threat hunting, operations, and response at Microsoft's GitHub, had identified the culprit: a GitHub Actions Workflow that clones a Mercurial repo and has been forked more than 700 of times. "Microsoft and GitHub have investigated the issue and determined that a GitHub user updated a script within the FFmpeg-Builds project that pulled content from https://gmplib.org," explained Blacker. "This build was configured to run parallel simultaneous tests on 100 different types of computers/architectures. This activity does not appear to be nefarious. [GMP] appears to have limited infrastructure that could not sustain the limited, yet simultaneous requests." [...] As of last week, the excessive traffic was still an issue. "Our servers are fully available again, but that's the result of us adding all participating Microsoft network ranges to our firewall," the GMP project explains on its webpage. "We understand that we are far from the first project to take such measures against Github." The Register asked Granlund whether he was satisfied with Microsoft-GitHub's response, and he told us he had only heard once from Blacker. "I blocked about 40 IP ranges from accessing our web server," he explained. "A week after this started, there was still intensive traffic from the same IP addresses, perhaps 100 different Microsoft addresses all in all, belonging to about 40 ranges. The difference was that that traffic just caused minuscule load, and a log line in the firewall." "Problem solved. I cannot care less if they no longer can access gmplib.org. I find it interesting how little responsibility Github/Microsoft assume here. They seem to think that they are entitled to bash away at smaller sites."

Let’s Encrypt Outage--Did Anybody Notice?
by Lawrence D'Oliveiro 29 Jun '23

29 Jun '23

Just noticed a mention in passing in this article <https://www.theregister.com/2023/06/28/microsofts_github_gmp_project/> that Let’s Encrypt was issuing bad certificates over a period of about an hour earlier this month <https://letsencrypt.status.io/pages/incident/55957a99e800baa4470002da/648b3…>. An explanation of what went wrong (from a third party who does monitoring of CA (mis)behaviour as part of his job) is here <https://www.agwa.name/blog/post/last_weeks_lets_encrypt_downtime>. Seems like many of the people affected were still using their bad certificates a week after the incident. Did you have one of the bad certificates? That article mentions a new addition to the ACME auto-renewal protocols that would allow clients to resolve a glitch like this in future without any manual intervention.

The Linux coders turning the ROG Ally and other handhelds into Steam Deck clones
by Peter Reutemann 28 Jun '23

28 Jun '23

'As soon as I was done with my review of the Asus ROG Ally, I grabbed my best USB stick and started looking for ISOs to download. Windows is, of course, the main highway to most PC gaming, but it's also (as detailed in the review) not yet built to work well on a 7-inch gaming handheld. The ROG Ally ships with Windows (Home) installed and a bunch of Asus software, but it is still, at heart, a PC. With effort, you can get into the BIOS, disable Secure Boot, plug in a USB stick, and boot a USB stick with a live Linux distribution on it. [...] With Ubuntu 23.04 installed, I could run the Phoronix Test Suite and run glxgears, which showed that at least some kind of 3D acceleration was happening. I installed Cyberpunk 2077 through Steam's Proton compatibility tool, benchmarked it, and got, well, very sad numbers. Cyberpunk saw that my GPU was the Ally's key feature—an AMD Ryzen Z1 Extreme. But it ran at 17 and 23 frames per second averages on "Medium" and "Steam Deck" settings, respectively (at 720p resolution and 60 Hz refresh rate). With nothing to lose, I installed the latest AMD Linux drivers, ran those benchmarks again, and lo and behold, improvement: 30.8 and 27.32 fps on "Medium" and "Steam Deck." That's notably shy of the 38 and 34 frames per second I clocked on the same benchmark in Windows. Then again, I'm guessing at drivers, and I can't do much to control thermals or power draw.' -- source: https://arstechnica.com/gadgets/2023/06/the-linux-coders-turning-the-rog-al… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Foundation Celebrates Zephyr Project's Small Real-Time Operating System
by Peter Reutemann 27 Jun '23

27 Jun '23

'This week the Linux Foundation shared an update on the Zephyr Project, a small real-time operating system for connected, resource-constrained and embedded devices: The project recently achieved several milestones including surpassing 80,000 commits since it was released in open source in 2015. This is an average of almost 2 commits per hour, which was made recently by 490 individuals, including 166 first-timers, who contributed to the 3.4 release. Zephyr RTOS supports over 450 boards running embedded microcontrollers from Arm and RISC-V to Tensilica, NIOS, ARC and x86 as single and multicore systems... Zephyr RTOS has a growing set of software libraries that can be used across various applications and industry sectors such as Industrial IoT, wearables, machine learning and more. It is built with an emphasis on broad chipset support, security, dependability, long-term support releases and a growing open source ecosystem... The Zephyr community will be at the Zephyr Developer Summit, which takes place on June 27-30 in Prague, Czech Republic, and virtually as part of the first-ever Embedded Open Source Summit. [Register here for virtual attendance.] Arduino will be joining Zephyr's Technical Steering Committee, along with Technology Innovation Institute and the American multinational semiconductor company Analog Devices (or ADI, who will also be joining its governing board). Arduino's CEO said "We believe that Zephyr OS is a truly special project that will play a significant role in the Arduino ecosystem and will be a big priority for us." As a "Platinum"-level sponsor, ADI joins Antmicro, Baumer, Google, Intel, Meta, Nordic Semiconductor, NXP, Oticon, Qualcomm Innovation Center and T-Mobile.' -- source: https://news.slashdot.org/story/23/06/26/0234245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
