OpenBSD aims to be a secure operating system. In the past few months there were quite a few security errata, however. That’s not too unusual, but some of the recent ones were a bit special. One might even say bad. The OpenBSD approach to security has a few aspects, two of which might be avoiding errors and minimizing the risk of mistakes. Other people have other ideas about how to build secure systems. I think it’s worth examining whether the OpenBSD approach works, or if this is evidence that it’s doomed to failure. I picked a few errata, not all of them, that were interesting and happened to suit my narrative.

Honda has done what no other car maker is doing, and returned to analogue controls for some functions on the new Honda Jazz. While most manufacturers are moving to touchscreen controls, identifying smartphone use as their inspiration – most recently seen in Audi’s latest A3 – Honda has decided to reintroduce heating and air conditioning controls via a dial rather than touchscreen, as in the previous-generation Jazz. Unlike what the introduction states, Honda joins fellow Japanese car maker Mazda in not just blindly using touchscreens for everything inside cars. This is a good move, and definitely takes some guts, since I’ve seen countless car reviewers – including my standout favourite, Doug DeMuro – kind of blindly assuming that any car without 100% touchscreen control is outdated, without questioning the safety consequences. Good on Honda.

When AMD introduced its Ryzen 4000 mobile CPUs at CES, the company made bold claims of game-changing performance. Coming off of years of underwhelming laptop chips, AMD promised it had optimized Ryzen 4000 for mobile computing. Now we’ve tested those claims in AMD’s Ryzen 9 4900HS chip, an 8-core, 7nm chip with Radeon Vega cores. We’re stunned at the CPU’s impressive tour de force that defeats just about every Intel 8th- and 9th-gen laptop CPU we’ve ever seen. Just open up your YouTube feed and you’ll see pretty much every PC hardware channel staring at disbelief in just how good AMD’s Ryzen 4000 mobile processors really are. This isn’t just a “kind of good enough” processor – the top of the line model is faster than or equal than Intel’s top of the line processor at both single core and multicore workloads, while using slightly more than half the power. It’s all well and good for AMD to roundly run circles around Intel in the server and desktop/workstation space, but the laptop space is where the real money and mindshare can be found. This new line of AMD mobile processors is simply stunning.

Earlier this evening, Linus released Linux 5.6, which contains our first release of WireGuard. This is quite exciting. It means that kernels from here on out will have WireGuard built-in by default. And for those of you who were scared away prior by the “dOnT uSe tHiS k0de!!1!” warnings everywhere, you now have something more stable to work with. The last several weeks of 5.6 development and stabilization have been exciting, with our codebase undergoing a quick security audit, and some real headway in terms of getting into distributions. WireGuard is probably the biggest new feature in 5.6, announced earlier today.

Here you’ll find my complete set of posts covering the Amiga Machine Code course. The course consists of twelve letters and two disks, that can be found here. The letters are available as PDF’s in their original Danish language as well as translated to English. Some light reading for the weekend.

If you have music on a collection of MiniDisc media and want to finally copy the data off onto modern media (or the cloud!), here are simple instructions for some different solutions. Why would you stop using MiniDisc though?

AMD has filed at least two DMCA notices against Github repos that carried “stolen” source code relating to AMD’s Navi and Arden GPUs, the latter being the processor for the upcoming Xbox Series X. The person claiming responsibility for the leak informs TorrentFreak that if they doesn’t get a buyer for the remainder of the code, they will dump the whole lot online. I’d love to hear the backstory behind this hack. For a company like AMD, such a hack must’ve been an inside job, right? While I know I shouldn’t be surprised anymore by just how lacking security can be at even the most prominent technology companies, I just can’t imagine it being very easy to get your hands on this documentation and code without some form of inside help.

For those managing to get their hands on a recently released Loongson 3A4000/3B4000 or even older Loongson 3 MIPS64 processors, improving the support is on the way with the upcoming Linux 5.7 kernel. Queued as part of the MIPS architecture work for Linux 5.7 are a number of Loongson improvements, in particular for the Loongson 3 series. The Loongson processors are pretty much impossible to come by outside of China, and gained some fame as the platform of choice for Richard Stallman.

Ever wondered what’s it like to run Android without Google’s services and applications? Well, get a Huawei device. A smartphone UI isn’t much use without apps, of course, and here is where Huawei hits its first hurdle. Huawei has its own store called AppGallery, which it claims is the third largest in the world based on its more than 400 million monthly active users. The vast majority of those users will be in China, of course, where the Google Play Store has never been included alongside AppGallery. If you buy a Mate 30 Pro now anywhere in the world, though, AppGallery is what you get out of the box. To be blunt, it is not great. I wouldn’t call it barren — there is support from major US companies like Microsoft, Amazon, and Snap. You can’t get Chrome, of course, but Opera is there if you want something with desktop sync. But a huge amount of its content is aimed at China, with other big Western names like Facebook, Slack, Netflix, and Twitter missing, which puts the Mate 30 Pro in a more precarious app situation than even the diciest days of Windows Phone. Huawei has announced a $1 billion plan to help stock AppGallery’s shelves, but it has its work cut out. A bigger problem is that even if you can get popular applications installed, they often won’t work properly because the device lacks the Google Mobile Services. It’s an incredibly hard situation for Huawei to be in.

Google announced its decision to drop support for the User-Agent string in its Chrome browser. Instead, Chrome will offer a new API called Client Hints that will give the user greater control over which information is shared with websites. We’ve talked about this earlier this year, but I want to highlight it again since it’s very important this initiative doesn’t devolve into Google and Chrome shoving this alternative down the web’s throat. Deprecating user agent strings is a good thing, but only if the replacement is a collective effort supported by everyone.

When Apple CarPlay and Android Auto first started rolling out, initial evidence suggested these technologies held promise to reduce distracted driving. These systems funneled the most important features from our phones onto the infotainment screen, curbing motorists’ desire to reach for their handhelds. Yet, it looks like these mirroring technologies may not be nearly as safe as initially hoped. A new study from the UK’s IAM Roadsmart, an independent road safety organization, paints a far bleaker picture. The stark findings showed that drivers using one of the smartphone mirroring systems in a car displayed reaction times slower than someone who’d used cannabis. In fact, these motorists’ reaction times were five times slower than someone driving with the legal limit of alcohol in their system. This shouldn’t come as a surprise to anyone with more than two braincells to rub together. These systems are based on touch screen technology, and touchscreens without any tactility are simply not suited for use while operating a motor vehicle. Touchscreens are far more distracting than plain old tactile buttons in a fixed order that you learn over time and can feel, and it blows my mind that no safety regulations heavily curtailing their use to parked situations has been enacted just yet.

The Counterpoint program launcher was supplied with the Amstrad PC5086 and other Amstrad PCs from that era. It acts as a user-friendly front end, replacing the full GUIs (Windows 2.0, or GEM) supplied with previous models. The Amstrad-branded version opens with a warning that it should only be used on Amstrad computers. However it appears to run successfully in non-Amstrad environments, such as the virtual machine used to make these screenshots. I love discovering user interfaces I’ve never known about this before, and this one fits the bill just right. Wild UI experimentation was the norm during the late ’80s and early ’90s, before we all settled on what we’re all using now. Digging into the past and learning from even relatively obscure footnotes such as these is fascinating.

Usually, x86 tutorials don’t spend much time explaining the historical perspective of design and naming decisions. When learning x86 assembly, you’re usually told something along the lines: Here’s EAX. It’s a register. Use it. So, what exactly do those letters stand for? E–A–X. I’m afraid there’s no short answer! We’ll have to go back to 1972… I love digital archeology.

We have seen earlier that Microsoft’s designers are working on a new Start Menu for Windows 10 (not Windows 10X) and now Panos Panay has posted a video celebrating 1 billion Windows 10 installations which appears to confirm that the changes and more are on the way. There’s finally hopefully going to be a modern replacement for Explorer, and context menus seem to be modern and thus consistent too. The already mentioned updated Stert menu is coming, too.
