As of the previous release of POSIX, the Austin Group gained more control over the specification, having it be more working group oriented, and they got to work making the POSIX specification more modern. POSIX 2024 is the first release that bears the fruits of this labor, and as such, the changes made to it are particularly interesting, as they will define the direction of the specification going forwards. This is what this article is about! Well, mostly. POSIX is composed of a couple of sections. Notably XBD (Base Definitions, which talk about things like what a file is, how regular expressions work, etc), XSH (System Interfaces, the C API that defines POSIX’s internals), and XCU (which defines the shell command language, and the standard utilities available for the system). There’s also XRAT, which explains the rationale of the authors, but it’s less relevant for our purposes today. XBD and XRAT are both interesting as context for XSH and XCU, but those are the real meat of the specification. This article will focus on the XCU section, in particular the utilities part of that section. If you’re more interested in the XSH section, there’s an excellent summary page by sortix’s Jonas Termansen that you can read here. ↫ im tosti The weekend isn’t over yet, so here’s some more light reading.

Old Vintage Computing Research, by the incredibly knowledgeable Cameron Kaiser, is one of the best resources on the web about genuinely obscure retrocomputing, often diving quite deep in topics nobody else covers – or even can cover, considering how rare some of the hardware Kaiser covers is. I link to Old VCR all the time, and today I’ve got two more great articles by Kaiser for you. First, we’ve got the more well-known – relatively speaking – of the two devices covered today, and that’s the MIPS ThinkPad, officially known as the IBM WorkPad z50. This was a Windows CE 2.11 device powered by a NEC VR4120 MIPS processor, running at 131 Mhz, released in 1999. Astute readers might note the WorkPad branding, which IBM also used for several rebranded Palm Pilots. Kaiser goes into his usual great detail covering this device, with tons of photos, and I couldn’t stop reading for a second. There’s so much good information in here I have no clue what to highlight, but since OSNews has OS in the name, this section makes sense to focus on: The desktop shortcuts are pre-populated in ROM along with a whole bunch of applications. The marquee set that came on H/PC Pro machines was Microsoft Pocket Office (Pocket Word, Pocket Excel, Pocket Access and Pocket PowerPoint), Pocket Outlook (Calendar, Contacts, Inbox and Tasks) and Pocket Internet Explorer, but Microsoft also included Calculator, InkWriter (not too useful on the z50 without a touch screen), Microsoft Voice Recorder, World Clock, ActiveSync (a la Palm HotSync), PC Link (direct connect, not networked), Remote Networking, Terminal (serial port and modem), Windows Explorer and, of course, Solitaire. IBM additionally licensed and included some of bSquare’s software suite, including bFAX Pro for sending and receiving faxes with the softmodem, bPRINT for printing and bUSEFUL Backup Plus for system backups, along with a battery calibrator and a Rapid Access quick configuration tool. There is also a CMD.EXE command shell, though it too is smaller and less functional than its desktop counterpart. ↫ Old Vintage Computing Research Using especially these older versions of Windows CE is a wild experience, because you can clearly tell Microsoft was trying really hard to make it look and feel like ‘normal’ Windows, but as anyone who used Windows CE back then can attest, it was a rather poor imitation with a ton of weird limitations and design decisions borne from the limited hardware it was designed to run on. I absolutely adore the various incarnations of Windows CE and associated graphical shells it ran – especially the PocketPC days – but there’s no denying it always felt quite clunky. Moving on, the second Old VCR article I’m covering today is more difficult for me to write about, since I am too young to have any experience with the 8 bit era – save for some experience with the MSX platform as a wee child – so I have no affinity for machines like the Commodore 64 and similar machines from that era. And, well, this article just so happens to be covering something called the Commodore HHC-4. Once upon a time (and that time was Winter CES 1983), Commodore announced what was to be their one and only handheld computer, the Commodore HHC-4. It was never released and never seen again, at least not in that form. But it turns out that not only did the HHC-4 actually exist, it also wasn’t manufactured by Commodore — it was a Toshiba. Like Superman had Clark Kent, the Commodore HHC-4 had a secret identity too: the Toshiba Pasopia Mini IHC-8000, the very first portable computer Toshiba ever made. And like Clark Kent was Superman with glasses, compare the real device to the Commodore marketing photo and you can see that it’s the very same machine modulo a plastic palette swap. Of course there’s more to the story than that. ↫ Old Vintage Computing Research Of course, Kaiser hunted down an IHC-8000, and details his experiences with the little handheld, calculator-like machine. It turns out it’s most likely using some unspecified in-house Toshiba architecture, running at a few hundred kHz, and it’s apparently quite sluggish. It never made it to market in Commodore livery, most likely because of its abysmal performance. The amount of work required to make this little machine more capable and competitive probably couldn’t be recouped by its intended list price, Kaiser argues.

There’s a date looming on the horizon for the vast majority of Windows users. While Windows 11 has been out for a long time now, most Windows users are using Windows 10 – about 63% – while Windows 11 is used by only about 33% of Windows users. In October 2025, however, support for Windows 10 will end, leaving two-thirds of Windows users without the kind of updates they need to keep their system secure and running smoothly. Considering Microsoft is in a lot of hot water over its security practices once again lately, this must be a major headache for the company. The core of the problem is that Windows 11 has a number of very strict hardware requirements that are mostly entirely arbitrary, and make it impossible for huge swaths of Windows 10 users to upgrade to Windows 11 even if they wanted to. And that is a problem in and of itself too: people don’t seem to like Windows 11 very much, and definitely prefer to stick to Windows 10 even if they can upgrade. It’s going to be quite difficult for Microsoft to convince those people to upgrade, which likely won’t happen until these people buy a new machine, which in turn in something that just isn’t necessary as often as it used to be. That first group of users – the ones who want to upgrade, but can’t – do have unofficial options, a collection of hacks to jank Windows 11 into installing on unsupported hardware. This comes with a number of warnings from Microsoft, so you may wonder how much of a valid option this really is. Ars Technica has been running Windows 11 on some unsupported machines for a while, and concludes that while it’s problem-free in day-to-day use, there’s a big caveat you won’t notice until it’s time for a feature update. These won’t install without going through the same hacks you needed to use when you first installed Windows 11 and manually downloading the update in question. This essentially means you’ll need to repeat the steps for doing a new unsupported Windows 11 install every time you want to upgrade. As we detail in our guide, that’s relatively simple if your PC has Secure Boot and a TPM but doesn’t have a supported processor. Make a simple registry tweak, download the Installation Assistant or an ISO file to run Setup from, and the Windows 11 installer will let you off with a warning and then proceed normally, leaving your files and apps in place. Without Secure Boot or a TPM, though, installing these upgrades in place is more difficult. Trying to run an upgrade install from within Windows just means the system will yell at you about the things your PC is missing. Booting from a USB drive that has been doctored to overlook the requirements will help you do a clean install, but it will delete all your existing files and apps. ↫ Andrew Cunningham at Ars Technica The only way around this that may work is yet another hack, which tricks the update into thinking it’s installing Windows Server, which seems to have less strict requirements. This way, you may be able to perform an upgrade from one Windows 11 version to the next without losing all your data and requiring a fresh installation. It’s one hell of a hack that no sane person should have to resort to, but it looks like it might be an inevitability for many. October 2025 is going to be a slaughter for Windows users, and as such, I wouldn’t be surprised to see Microsoft postponing this date considerably to give the two-thirds of Windows users more time to move to Windows 11 through their regular hardware replacements cycles. I simply can’t imagine Microsoft leaving the vast majority of its Windows users completely unprotected. Spare a thought for our Windows 10-using friends. They’re going to need it.

If you love exploit mitigations, you may have heard of a new system call named mseal landing into the Linux kernel’s 6.10 release, providing a protection called “memory sealing.” Beyond notes from the authors, very little information about this mitigation exists. In this blog post, we’ll explain what this syscall is, including how it’s different from prior memory protection schemes and how it works in the kernel to protect virtual memory. We’ll also describe the particular exploit scenarios that mseal helps stop in Linux userspace, such as stopping malicious permissions tampering and preventing memory unmapping attacks. ↫ Alan Cao The goal of mseal is to, well, literally seal a part of memory and protect its contents from being tampered with. It makes regions of memory immutable so that while a program is running, its memory contents cannot be modified by malicious actors. This article goes into great detail about this new feature, explains how it works, and what it means for security in the Linux kernel. Excellent light reading for the weekend.

Windows 11, version 24H2 represents significant improvements to the already robust update foundation of Windows. With the latest version, you get reduced installation time, restart time, and central processing unit (CPU) usage for Windows monthly updates. Additionally, enhancements to the handling of feature updates further reduce download sizes for most endpoints by extending conditional downloads to include Microsoft Edge. Let’s take a closer look at these advancements. ↫ Steve DiAcetis at the Windows IT Pro Blog Now this is the kind of stuff we want to see in new Windows releases. Updating Windows feels like a slow, archaic, and resource-intensive process, whereas on, say, my Fedora machines it’s such an effortless, lightweight process I barely even notice it’s happening. This is an area where Windows can make some huge strides that materially affect people – Windows updates are a meme – and it’s great to see Microsoft working on this instead of shoving more ads onto Windows users’ desktops. In this case, Microsoft managed to reduce installation time, make reboots faster, and lower CPU and RAM usage through a variety of measures roughly falling in one of three groups: improved parallel processing, faster and optimised reading of update manifests, and more optimal use of available memory. We’re looking at some considerable improvements here, such as a 45% reduction in installation time, 15-25% less CPU usage, and more. Excellent work. On a related note, at the Qualcomm Snapdragon Summit, Microsoft also unveiled a number of audio improvements for Windows on ARM that will eventually also make their way to Windows on x86. I’m not exactly an expert on audio, but from what I understand the Windows audio stack is robust and capable, and what Microsoft announced today will improve the stack even further. For instance, support for MIDI 2.0 is coming to Windows, with backwards compatibility for MIDI 1.0 devices and APIs, and Microsoft worked together with Yamaha and Qualcomm to develop a new USB Audio Class 2 Driver. In the company’s blog post, Microsoft explains that the current USB Audio Class 2 driver in Windows is geared towards consumer audio applications, and doesn’t fulfill the needs of professional audio engineers. This current driver does not support the standard professional software has standardised on – ASIO – forcing people to download custom, third-party kernel drivers to get this functionality. That’s not great for anybody, and as such they’re working on a new driver. The new driver will support the devices that our current USB Audio Class 2 driver supports, but will increase support for high-IO-count interfaces with an option for low-latency for musician scenarios. It will have an ASIO interface so all the existing DAWs on Windows can use it, and it will support the interface being used by Windows and the DAW application at the same time, like a few ASIO drivers do today. And, of course, it will handle power management events on the new CPUs. ↫ Pete Brown at the Dev Blogs The code for this driver will be published as open source on GitHub, so that anyone still opting to make a specialised driver can use Microsoft’s code to see how things are done. That’s a great move, and one that I think we’ll be seeing more often from Microsoft. This is great news for audio professionals using Windows.

The processor in the Game Boy Advance, the ARM7TDMI, has a weird characteristic where the carry flag is set to a “meaningless value” after a multiplication operation. What this means is that software cannot and should not rely on the value of the carry flag after multiplication executes. It can be set to anything. Any value. 0, 1, a horse, whatever. This has been a source of memes in the emulator development community for a few years – people would frequently joke about how the implementation of the carry flag may as well be cpu.flags.c = rand() & 1;. And they had a point – the carry flag seemed to defy all patterns; nobody understood why it behaves the way it does. But the one thing we did know, was that the carry flag seemed to be deterministic. That is, under the same set of inputs to a multiply instruction, the flag would be set to the same value. This was big news, because it meant that understanding the carry flag could give us key insight into how this CPU performs multiplication. And just to get this out of the way, the carry flag’s behavior after multiplication isn’t an important detail to emulate at all. Software doesn’t rely on it. And if software did rely on it, then screw the developers who wrote that software. But the carry flag is a meme, and it’s a really tough puzzle, and that was motivation enough for me to give it a go. Little did I know it’d take 3 years of on and off work. ↫ bean machine Please don’t make me understand any of this.

At the Snapdragon Summit today, Qualcomm is officially announcing the Snapdragon 8 Elite, its flagship SoC for smartphones. The Snapdragon 8 Elite is a major upgrade from its predecessor, with improvements across the board. Qualcomm is also changing its naming scheme for its flagship SoCs from Snapdragon 8 Gen X to Snapdragon X Elite. ↫ Pradeep Viswanathan at Neowin It’s wild – but not entirely unexpected – how we always seem to end up in a situation in technology where crucial components, such as the operating system or processor, are made by one, or at most two, companies. While there are a few other smartphone system-on-a-chip vendors, they’re mostly relegated to low-end devices, and can’t compete on the high end, where the money is, at all. It’s sadness. Speaking of our mobile SoC overlords, they seem to be in a bit of a pickle when it comes to their core business of, well, selling SoCs. In short, Qualcomm bought Nuvia to use its technology to build the current crop of Snapdragon X Elite and Pro laptop chips. According to ARM, Qualcomm does not have an ARM license to do so, and as such, a flurry of lawsuits between the two companies followed. ARM is now cancelling certain Qualcomm ARM licenses, arguing specifically its laptop Snapdragon X chips should be destroyed. What we’re looking at here is two industry giants engaged in very public, and very expensive, contract negotiations, using the legal system as their arbiter. This will eventually fizzle out into a new agreement between the two companies with renewed terms and conditions – and flows of money – but until that dust has settled, be prepared for an endless flurry of doomerist news items about this story. As for us normal people? We don’t have to worry one bit about this legal nonsense. It’s not like we have any choice in smartphone chips anyway.

I commented on Lobsters that /tmp is usually a bad idea, which caused some surprise. I suppose /tmp security bugs were common in the 1990s when I was learning Unix, but they are pretty rare now so I can see why less grizzled hackers might not be familiar with the problems. I guess that’s some kind of success, but sadly the fixes have left behind a lot of scar tissue because they didn’t address the underlying problem: /tmp should not exist. ↫ Tony Finch Not only is this an excellent, cohesive, and convincing argument against the existence of /tmp, it also contains some nice historical context as to why things are the way they are. Even without the arguments against /tmp, though, it just seems entirely more logical, cleaner, and sensible to have /tmp directories per user in per user locations. While I never would’ve been able to so eloquently explain the problem as Finch does, it just feels wrong to have every user resort to the exact same directory for temporary files, like a complex confluence of bad decisions you just know is going to cause problems, even if you don’t quite understand the intricate interplay.

System76, purveyor of Linux computers, distributions, and now also desktop environments, has just unveiled its latest top-end workstation, but this time, it’s not an x86 machine. They’ve been working together with Ampere to build a workstation based around Ampere’s Altra ARM processors: the Thelio Astra. Phoronix, fine purveyor of Linux-focused benchmarks, were lucky enough to benchmark one, and has more information on the new workstation. System76 designed the Thelio Astra in collaboration with Ampere Computing. The System76 Thelio Astra makes use of Ampere Altra processors up to the Ampere Altra Max 128-core ARMv8 processor that in turn supports 8-channel DDR4 ECC memory. The Thelio Astra can be configured with up to 512GB of system memory, choice of Ampere Altra processors, up to NVIDIA RTX 6000 Ada Generation graphics, dual 10 Gigabit Ethernet, and up to 16TB of PCIe 4.0 NVMe SSD storage. System76 designed the Thelio Astra ARM64 workstation to be complemented by NVIDIA graphics given the pervasiveness of NVIDIA GPUs/accelerators for artificial intelligence and machine learning workloads. The Astra is contained within System76’s custom-designed, in-house-manufactured Thelio chassis. Pricing on the System76 Thelio Astra will start out at $3,299 USD with the 64-core Ampere Altra Q64-22 processor, 2 x 32GB of ECC DDR4-3200 memory, 500GB NVMe SSD, and NVIDIA A402 graphics card. ↫ Michael Larabel This pricing is actually remarkably favourable considering the hardware you’re getting. System76 and its employees have been dropping hints for a while now they were working on an ARM variant of their Thelio workstation, and knowing some of the prices others are asking, I definitely expected the base price to hit $5000, so this is a pleasant surprise. With the Altra processors getting a tiny bit long in the tooth, you do notice some oddities here, specifically the DDR4 RAM instead of the modern DDR5, as well as the lack of PCIe 5.0. The problem is that while the Altra has a successor in the AmpereOne processor, its availability is quite limited, and most of them probably end up in datacentres and expensive servers for big tech companies. This newer variant does come with DDR5 and PCIe 5.0 support, but doesn’t yet have a lower core count version, so even if it were readily available it might simply push the price too far up. Regardless, the Altra is still a ridiculously powerful processor, and at anywhere between 64 and 128 cores, it’s got power to spare. The Thelio Astra will be available come 12 November, and while I would perform a considerable number of eyebrow-raising acts to get my hands on one, it’s unlikely System76 will ship one over for a review. Edit: here’s an excellent and detailed reply to our Mastodon account from an owner of an Ampere Altra workstation, highlighting some of the challenges related to your choice of GPU.

How a vehicle’s accident history influences insurance premiums holds the key to making a better decision about car purchase. Higher accident-proneness translates to a higher premium amount; hence, the impact on the overall cost of owning and running the car is enormous. This article explores the relationship between a vehicle’s accident history and the premium for insurance owing to that vehicle. It underlines the importance of knowing it before purchasing it. Consumers must also determine how old accidents might impact the ability of the car to protect the occupants or last long enough without significant failures. Moreover, some insurance companies will not insure or charge higher deductibles on such vehicles because of the history of high-severity crashes. Knowing about such indirect impacts can help consumers negotiate terms and avoid surprise financial liabilities. How Accident History Affects Insurance Premiums Insurance companies take a risk when they calculate premiums. The car’s history of accidents can reflect a part of that risk: the more accidents a vehicle has been associated with, the higher the premium. A car in several accidents may be considered high-risk, whereas a vehicle with no accident history would be given lower rates. Potential buyers should thoroughly research a vehicle’s history to make informed decisions. Resources like a Texas VIN Lookup can provide essential insights into whether the car has been involved in any accidents. By entering the Vehicle Identification Number (VIN) into a reliable service, buyers can access detailed reports that outline the car’s past, including any reported accidents and their severity. The Role of Insurance Companies Insurance companies consider a variety of factors when determining premiums, including: Understanding these factors can help consumers anticipate the costs of insuring a used vehicle. The Importance of Vehicle History Reports These reports contain important information about the involvement of the vehicle in accidents in the past, the status of the title, and other information that could affect the insurance rates. Services like StatReport give detailed VIN checks showing if the motor vehicle has been involved in an accident and the resultant damage. The reports sometimes include previous owners, service records, accident history, etc. This transparency allows likely buyers to make informed decisions about the vehicles they put into consideration. Knowing a vehicle’s history will help buyers avoid buying cars with concealed problems that can cost them many resources in repairs. By looking at the report, they will also know if the asking price is to the book. Hidden Costs of Accident-Damaged Vehicles Buying a car with an accident history may cost more due to insurance; there may also be some hidden costs. Some of the possible problems include: Checking for Stolen Vehicles In addition to examining accident history, checking whether the vehicle has been reported stolen is crucial. A stolen vehicle check is essential in ensuring you are not inadvertently purchasing a car with legal complications. Many VIN check services provide this information as part of their reports. Knowing whether a vehicle has been reported stolen can save you from potential legal issues and financial losses. If you buy a stolen vehicle unknowingly, you could lose both your investment and the car itself once law enforcement gets involved. Understanding State-Specific Regulations Each state has regulations regarding how accidents affect insurance rates and what information must be disclosed when selling a vehicle. Familiarising yourself with these regulations is vital for protecting your rights as a consumer. For example, some states require sellers to disclose any known accidents or damage when selling a used car. Understanding these laws can empower buyers to ask the right questions and demand transparency from sellers. The Role of Professional Inspections Moreover, in addition to the vehicle history report, each used car being sold to a potential buyer should be taken for a professional inspection. A qualified mechanic might reveal prospective issues related to accidents that have taken place with the car in the past, which might not be visible if one were to conduct a casual inspection. A careful examination might reveal poor repairs or structural damage that could impact safety and performance. This additional level of scrutiny safeguards the buyer by ensuring that he is informed of what he is getting himself into before making any financial commitment. Conclusion They have a significant relationship with insurance rates. While the happening of an accident increases the rate, the effect of an accident on insurance is one of the most misunderstood subjects for a vehicle. Buyers need to understand, while making a purchase decision, how the accident history affects the premium for a car. The Texas VIN Lookup services, entire vehicle history reports, and the like come into play here to help buyers avoid hidden costs and probable risks in buying a pre-owned or secondhand car. Accidents in its history impact insurance rates, resale prices, and the cost of keeping the car on the road. The confidence that comes with researching a vehicle for purchase, combined with seeking a professional inspection of it, allows buyers to make appropriate selections conducive to their financial goals and personal safety concerns. Knowledge is power- the more informed one is about these factors, the better a used vehicle purchase decision can be made.

In early 2022 I got several Sun SPARC servers for free off of a FreeCycle ad: I was recently called out for not providing any sort of update on those devices… so here we go! ↫ Sidneys1.com Some information on booting old-style SPARC machines, as well as pretty pictures. Nice palate-cleanser if you’ve had to deal with something unpleasant this weekend. This world would be a better place if we all had our own Sun machines to play with when we get sad.

I don’t think most people realize how Firefox and Safari depend on Google for more than “just” revenue from default search engine deals and prototyping new web platform features. Off the top of my head, Safari and Firefox use the following Chromium libraries: libwebrtc, libbrotli, libvpx, libwebp, some color management libraries, libjxl (Chromium may eventually contribute a Rust JPEG-XL implementation to Firefox; it’s a hard image format to implement!), much of Safari’s cryptography (from BoringSSL), Firefox’s 2D renderer (Skia)…the list goes on. Much of Firefox’s security overhaul in recent years (process isolation, site isolation, user namespace sandboxes, effort on building with ControlFlowIntegrity) is directly inspired by Chromium’s architecture. ↫ Rohan “Seirdy” Kumar Definitely an interesting angle on the browser debate I hadn’t really stopped to think about before. The argument is that while Chromium’s dominance is not exactly great, the other side of the coin is that non-Chromium browsers also make use of a lot of Chromium code all of us benefit from, and without Google doing that work, Mozilla would have to do it by themselves, and let’s face it, it’s not like they’re in a great position to do so. I’m not saying I buy the argument, but it’s an argument nonetheless. I honestly wouldn’t mind a slower development pace for the web, since I feel a lot of energy and development goes into things making the web worse, not better. Redirecting some of that development into things users of the web would benefit from seems like a win to me, and with the dominant web engine Chromium being run by an advertising company, we all know where their focus lies, and it ain’t on us as users. I’m still firmly on the side of less Chromium, please.

Something odd happened to Qualcomm’s Snapdragon Dev Kit, an $899 mini PC powered by Windows 11 and the company’s latest Snapdragon X Elite processor. Qualcomm decided to abruptly discontinue the product, refund all orders (including for those with units on hand), and cease its support, claiming the device “has not met our usual standards of excellence.” ↫ Taras Buria at Neowin The launch of the Snapdragon X Pro and Elite chips seems to have mostly progressed well, but there have been a few hiccups for those of us who want ARM but aren’t interested in Windows and/or laptops. There’s this story, which is just odd all around, with an announced, sold, and even shipped product suddenly taken off the market, which I think at this point was the only non-laptop device with an X Elite or Pro chip. If you are interested in developing for Qualcomm’s new platform, but don’t want a laptop, you’re out of luck for now. Another note is that the SoC SKU in the Dev Kit was clocked a tiny bit higher than the laptop SKUs, which perhaps plays a role in its cancellation. The bigger hiccup is the problematic Linux bring-up, which is posing many more problems and is taking a lot longer than Qualcomm very publicly promised it would take. For now, if you want to run Linux on a Snapdragon X Elite or Pro device, you’re going to need a custom version of your distribution of choice, tailored to a specific laptop model, using a custom kernel. It’s an absolute mess and basically means that at this point in time, months and months after release, buying one of these to run Linux on them is a bad idea. Quite a few important bits will arrive with Linux 6.12 to supposedly greatly improve the experience, but seeing is believing. Qualcomm made a lot of grandiose promises about Linux support, and they simply haven’t delivered.

I want to take advantage of Go’s concurrency and parallelism for some of my upcoming projects, allowing for some serious number crunching capabilities. But what if I wanted EVEN MORE POWER?!? Enter SIMD, Same Instruction Muliple Data . Simd instructions allow for parallel number crunching capabilities right down at the hardware level. Many programming languages either have compiler optimizations that use simd or libraries that offer simd support. However, (as far as I can tell) Go’s compiler does not utilizes simd, and I cound not find a general propose simd package that I liked. I just want a package that offers a thin abstraction layer over arithmetic and bitwise simd operations. So like any good programmer I decided to slightly reinvent the wheel and write my very own simd package. How hard could it be? After doing some preliminary research I discovered that Go uses its own internal assembly language called Plan9. I consider it more of an assembly format than its own language. Plan9 uses target platforms instructions and registers with slight modifications to their names and usage. This means that x86 Plan9 is different then say arm Plan9. Overall, pretty weird stuff. I am not sure why the Go team went down this route. Maybe it simplifies the compiler by having this bespoke assembly format? ↫ Jacob Ray Pehringer Another case of light reading for the weekend. Even as a non-programmer I learned some interesting things from this one, and it created some appreciation for Go, even if I don’t fully grasp things like this. On top of that, at least a few of you will think this has to do with Plan9 the operating system, which I find a mildly entertaining ruse to subject you to.
