OpenBSD 7.0 has been released, and it seems a big focus for this release was improving ARM64 support, and adding support for RISC-V. There’s a long list or other improvements and fixes, too, of course. Downloads are where they always are.
Microsoft delivers the latest Windows security and user experiences updates monthly. Updates are modular meaning that, regardless of which update you currently have installed, you only need the most recent quality update to get your machine up to date. With the fast pace of Windows security and quality fixes, distributing this large amount of updated content takes up substantial bandwidth. Reducing this network transfer is critical for a great experience. Moreover, users on slower networks can struggle to keep their machines up to date with the latest security fixes if they cannot download the package. This is the kind of grunt work that doesn’t get flashy slides in a presentation or a mention in a commercial, but it’s awesome work nonetheless.
Shortly after Windows 11 launch, AMD and Microsoft jointly discovered that Windows 11 is poorly optimized for AMD Ryzen processors, which see significantly increased L3 cache latency, and the UEFI-CPPC2 (preferred cores mechanism) rendered not working. In our own testing, a Ryzen 7 2700X “Pinnacle Ridge” processor, which typically posts an L3 cache latency of 10 ns, was tested to show a latency of 17 ns. This was made much worse with the October 12 “patch Tuesday” update, driving up the latency to 31.9 ns. That’s one hell of a regression. It seems fixes are incoming soon, though.
6.0.1 is tagged and available. The major reason for this update is an expired Let’s Encrypt certificate that would cause problems when downloading dpkg binaries. A list of 6.0.1 commits is available. Not a whole lot going on in this release, but still a major bug fix.
The 6502 was the CPU in my first computer (an Apple II plus), as well as many other popular home computers of the late 1970s and 80s. It lived on well into the 1990s in game consoles and chess computers, mostly in its updated “65C02” CMOS version. Here’s a re-implementation of the 65C02 in an FPGA, in a pin-compatible format that lets you upgrade those old computers and games to 100 MHz clock rate! Interesting project.
Another month has passed, so time for another monthly update from the Haiku team. This time around, we get two for the price of one. First, the regular monthly activity report, where we can read that work on the ARM64 and RISC-V ports continues, and while these ports are nowhere near complete, they serve an important function both in discovering bugs and issues, as well as in getting Haiku ready for future architecture transitions. Tracker also received thumbnail support, but this is disabled by default for now, and of course, there’s a lot of low-level work being done, too. The second update comes from waddlesplash, Haiku Inc.’s actual paid full-time developer. In his report, he details his work on fixing two Haiku bugs that caused frequent crashes in WebKit, as well as extensive work on the USB stack – more specifically, improving USB 3.0 support. On top of that, he also details a lot of his low-level work over the month of September.
In the mid-to-late 2000s, you either knew, or were, that kid in grade school. You know. The one who could put games on your graphing calculator. You may be surprised to learn that some of these people didn’t exist totally in a vacuum. There was in fact a thriving scene of hackers who had bent these calculators to their will, writing games, math software, and more generally hacking on the platform just for the sake of it. True to my interests, it’s all deeply embedded, pushing the limits of platforms that were obsolete when they were released. I’ll take you through some of the highlights of Texas Instruments calculator hacking done over the past two and a half decades, along with an explanation of why these projects are so technically impressive. A friend of mine and I at high school bought the data transfer cable for our graphing calculators so we could play multiplayer Bomberman on them in class. Good times.
In the years leading up to that launch, we’ve uncovered signs of the Fuchsia team developing support for a variety of Google devices, including the Nest Hub Max, 2021’s second-gen Nest Hub, and more. Now, it seems, Google is ready to make its next steps more public, in a series of job listings posted this week, some of which reference a “Fuchsia Devices” team. The job listings even make references to working with partners using Fuchsia, so there’s definitely more afoot for Google’s new operating system.
Microsoft’s Xbox and Surface hardware may be getting easier to repair, according to a press release from shareholder advocacy nonprofit As You Sow. According to the announcement, Microsoft has agreed to evaluate and expand the repair options for its products “by the end of 2022.” The promises are a bit vague for now, but hopefully this will have a real-world impact.
Quickly create and run highly optimised desktop virtual machines for Linux, macOS and Windows; with just two commands. You decide what operating system you want to run and Quickemu will figure out the best way to do it for you. Excellent idea.
This is an introduction to getting IBM’s OS/360 operating system loaded and running on the Hercules emulator for the System/370, ESA/390, and z/Architecture systems. It assumes you have some familiarity with the 370, and with OS; in particular, you need to have some understanding of JCL, and of OS/360 (or later versions, like MVS or OS/390) usage and operation. It does not purport to be an introduction to the world of the 370. This is a bit more complicated to set up than just about any other emulator or VM out there. A great weekend project for people with the right skill set and inclination.
For years now, Windows 10’s Windows Subsystem for Linux has been making life easier for developers, sysadmins, and hobbyists who have one foot in the Windows world and one foot in the Linux world. But WSL, handy as it is, has been hobbled by several things it could not do. Installing WSL has never been as easy as it should be—and getting graphical apps to work has historically been possible but also a pain in the butt that required some fairly obscure third-party software. Windows 11 finally fixes both of those problems. The Windows Subsystem for Linux isn’t perfect on Windows 11, but it’s a huge improvement over what came before. Microsoft is doing a decent job making Windows a good platform for Linux system administrators, but is WSL really comparable to the real thing?
On the competitive landscape, Ampere is carving out its niche for the moment, but what happens once AMD or Intel increase their core counts as well? A 50% increase in core counts for next-gen Genoa should be sufficient for AMD to catch up with the M128 in raw throughput, and technologies such as V-cache should make sure the HPC segment is fully covered as well, a segment Ampere appears to have no interest in. Intel now has an extremely impressive smaller core in the form of Gracemont, and they could easily make a large-core count server chip to attack the very segment Ampere is focusing on. Only time will tell if Ampere’s gamble on hyper-focusing on certain workloads and market segments pays out. For now, the new Altra Max is an interesting and very competent chip, but it’s certainly not for everyone. Admit it. You too want a 128-core ARM processor on your desk.
This Atari 1040ST is still in use after 36 years! Frans Bos bought this Atari in 1985 to run his camp site (Camping Böhmerwald). He wrote his own software over the years to manage his camp site, as well as reservations and the registration of the guests. He really likes the speed of the machine compared to newer computers. And 6 months every year the machine is on day and night.
Interview with Miguel de Icaza about his own journey, GNU, Linux, GNOME, and how he ended up working at Microsoft. It’s an interview for a mainstream audience, but with plenty of fun stories that should entertain any OSNews reader. I found it particularly interesting how de Icaza recounts his decades-long obsession to make Linux a great desktop OS, only to see it achieve massive success on server, mobile, and embedded devices, and never really catch on as a mainstream desktop OS. Today, he uses a Mac for his everyday platform while working at Microsoft.
Tracking quantum computing has been a bit confusing in that there are multiple approaches to it. Most of the effort goes toward what are called gate-based computers, which allow you to perform logical operations on individual qubits. These are well understood theoretically and can perform a variety of calculations. But it’s possible to make gate-based systems out of a variety of qubits, including photons, ions, and electronic devices called transmons, and companies have grown up around each of these hardware options. But there’s a separate form of computing called quantum annealing that also involves manipulating collections of interconnected qubits. Annealing hasn’t been as worked out in theory, but it appears to be well matched to a class of optimization problems. And, when it comes to annealing hardware, there’s only a single company called D-Wave. Now, things are about to get more confusing still. On Tuesday, D-Wave released its roadmap for upcoming processors and software for its quantum annealers. But D-Wave is also announcing that it’s going to be developing its own gate-based hardware, which it will offer in parallel with the quantum annealer. We talked with company CEO Alan Baratz to understand all the announcements. I think I understood some of those words because I, too, watch Space Time.
A desktop environment I had never heard of until now has seen its first new release in 611 days – always awesome to read about unknown projects like this, so here we go. Anyway onto the point, yes the project is still alive and there’s been some updates. This release encompasses two main things. First is a collection of minor fixes that have gone into master since 1.6.0 came out, along with some translation updates. This includes two small additional binaries for use by the desktop. Second is that the downstream theme work that we did for Project Trident is now in Lumina as the default theme. Lumina is an open source, lightweight desktop environment written from scratch in C++/Qt5. The related Project Trident is a desktop Linux distribution based on Void Linux – excellent taste, just excellent – that uses Lumina as its desktop environment.
It’s a symptom of what insiders say are deeper organizational problems that have left the health group without clear direction and struggling to mesh Apple’s hardware-oriented culture with the practices of the medical business. People at Apple Health said that they saw colleagues face retribution for disagreeing with superiors and that concerns have been expressed on more than one occasion about the way health data is used to develop products. The situation has gotten so serious that some employees have lodged complaints with Apple’s most senior executives, including Cook and Chief Operating Officer Jeff Williams, who oversees the health effort. Success tends to hide problems.
A day early, Microsoft has decided to release Windows 11. Today marks an exciting milestone in the history of Windows. As the day becomes October 5 in each time zone around the world, availability of Windows 11 begins through a free upgrade on eligible Windows 10 PCs and on new PCs pre-installed with Windows 11 that can be purchased beginning today. This is the first release of Windows I haven’t personally used or even tested, but much like Android 12 that’s also been released today, it seems to be a version heavily focused on giving Windows a fresh coat of paint, while sadly removing features and customisations and adding strict system requirements. As the detailed Ars Technica review concludes: Here’s the thing: I actually like Windows 11 pretty well, and as I’ve dug into it and learned its ins and outs for this review, I’ve warmed to it more. The window management stuff is a big step forward, the new look is appealing and functional, and the taskbar regressions mostly don’t bother me (the more you customized the taskbar and Start menu in Windows 10, though, the more the new version’s lack of flexibility will irritate you). Unfortunately for Microsoft, Windows 11 is going to be starting its life with some of the same public perception problems that made Windows Vista and Windows 8 relatively unpopular. Meanwhile, AnandTech concludes: I’ve only a had a short time with Windows 11, and that is partially due to how short of a public beta that it got compared to Windows 10. Already there are some features that I really enjoy. The new interfaces are well thought out and easy to use. But for me, the true test is using a new version of the OS and then stepping back to an older version. How painful is it? How many of the new features do I miss? There is no single item right now that is a must-have, so swapping between Windows 10 and Windows 11 is not a huge deal. And that’s good because Windows 10 is going to be around for years to come still. Some of the biggest new features announced for Windows 11 won’t even be shipping until next year. Perhaps if and when they arrive that will make the difference. Windows 11 just doesn’t seem like that big of a release to me, and depending on how much you enjoy using Windows, that can be a good thing or a bad thing. To me, it seems like this new UI theme is skin-deep, and underneath it all still lie countless layers of UI cruft dating all the way back to Windows 3.x.
