Why a rotary cellphone? Because in a finicky, annoying, touchscreen world of hyperconnected people using phones they have no control over or understanding of, I wanted something that would be entirely mine, personal, and absolutely tactile, while also giving me an excuse for not texting. The point isn’t to be anachronistic. It’s to show that it’s possible to have a perfectly usable phone that goes as far from having a touchscreen as I can imagine, and which in some ways may actually be more functional. Genius.

Steve Streza, developer and all-around good guy, writing about Apple turning iOS into adware: Over the years, Apple has built up a portfolio of services and add-ons that you pay for. Starting with AppleCare extended warranties and iCloud data subscriptions, they expanded to Apple Music a few years ago, only to dramatically ramp up their offerings last year with TV+, News+, Arcade, and Card. Their services business, taken as a whole, is quickly becoming massive; Apple reported $12.7 billion in Q1 2020 alone, nearly a sixth of its already gigantic quarterly revenue. All that money comes from the wallets of 480 million subscribers, and their goal is to grow that number to 600 million this year. But to do that, Apple has resorted to insidious tactics to get those people: ads. Lots and lots of ads, on devices that you pay for. iOS 13 has an abundance of ads from Apple marketing Apple services, from the moment you set it up and all throughout the experience. These ads cannot be hidden through the iOS content blocker extension system. Some can be dismissed or hidden, but most cannot, and are purposefully designed into core apps like Music and the App Store. There’s a term to describe software that has lots of unremovable ads: adware, which what iOS has sadly become. Apple, decidedly not an ad company, puts tons of ads into iOS, while Google, decidedly very much an ad company, puts basically zero ads in Android. Yet, this is something we rarely talk about because for some reason, we seem to just accept platform owners treating users like garbage and negatively impacting the user experience to try and get them to subscribe to “services”. Apple is undertaking a massive push to get iOS users to subscribe to more and more services, and the company has clearly shown it has no qualms about degrading the user experience to get there. And of course, while you can block every other company’s ads on iOS – you can’t block Apple’s ads, since the rules Apple sets for third parties don’t apply to Apple itself, and you can’t change your default applications either. Now that you’re locked into their ecosystem, Apple is going to try every sleazy tactic under the sun to try and get you to subscribe to their services. Have fun.

The NetBSD Project is pleased to announce NetBSD 9.0, the seventeenth major release of the NetBSD operating system. This release brings significant improvements in terms of hardware support, quality assurance, security, along with new features and hundreds of bug fixes. Support for the ARM architecture seems to be a major pillar of this new release.

In early May of 2019, Google submitted patches to merge support for the Incremental File System into the Linux kernel. According to the documentation that Google submitted, Incremental FS is a “special-purpose Linux virtual file system that allows execution of a program while its binary and resource files are still being lazily downloaded over the network, USB etc.” The purpose of this feature is “to allow running big Android apps before their binaries and resources are fully downloaded to an Android device.” Isn’t this already possible in various other ways, though? I mean, PlayStation 4 games can be played well before they’re entirely downloaded, as can Blizzard games, to name a few. I’m pretty sure those just load early-game assets first, so I’m not sure if that aligns with that Google is doing here, but this kind of feels like a solved problem.

Hot off the presses is our latest stable, version 1.5.0, marking the second stable release since the last progress report. In this past year, support has been added for multiple new platforms to make the emulator accessible, performance has dramatically increased, new features such as save states and cheat support have landed to make emulating more fun, and numerous accuracy improvements were made to continue polishing the overall emulation experience. I love these detailed overviews of changes in emulators. Dolphin started the trend, I think, and now this team is picking it up.

Besides the architectural progress, the CDC6600 was impressive for its clock speed of 10 MHz. This may not sound much, but consider that this was a physically very large machine entirely built from discrete resistors and transistors in the early 60ies. Not a single integrated circuit was involved. For comparison, the PDP-8, released in 1965 and also based on discrete logic, had a clock speed of 1.5 MHz. The first IBM PC, released 20 years later, was clocked at less than half the speed of the CDC6600 despite being based on integrated circuits. The high clockrate is even more impressive when comparing it to more recent (hobbyist) attempts to design CPUs with discrete components such as the MT15, the Megaprocessor or the Monster6502. Although these are comparatively small designs based on modern components, none of them get to even a tenth of the CDC6600 clock speed. Detailed look at the speed of the CDC6600.

Microsoft released its first emulator for Windows 10X today, allowing developers to get a first look at the new operating system variant for dual-screen devices. Microsoft wants to give developers a head start on optimizing apps before devices launch later this year, so this basic emulator provides an early look at Windows 10X before it’s finalized. My first thoughts? Windows 10X feels like a slightly more modern version of Windows 10 that has been cleaned up for future devices. In Windows 10X, everything is new. There’s none of the old Win32 code and applications lying around, or fallbacks to old Win32 dialogs. Everything is a Modern application (or whatever they call it these days), including things like the file manager – the traditional Explorer is gone. While Windows 10X does support Win32 applications, they run in a container. As detailed in this video from Microsoft (select the video titled “How Windows 10X runs UWP and Win32 apps”), Windows 10X has three containers – Win32, MSIX, and Native. Win32 applications run inside a single Win32 container, capable of running pretty much anything “classic” you can throw at it, such as Win32, WinForms, Electron, and so on. MSIX containers are basically slightly more advanced classic applications, and these containers run inside the Win32 container as well. The Native container runs all the modern/UWP applications. The Win32 container is actually a lot more involved than you might think. As you can see in the below overview diagram from the video, the container contains a kernel, drivers, the needed files, a registry, and so on. It’s effectively an entire traditional Win32 Windows operating system running inside Windows 10X. Applications running inside the Win32 container are entirely isolated from the rest of the host Windows 10X operating system, and Windows 10X interacts with them through specialised, performance-optimised RDP clients – one for each Win32 application. This seems to finally be what many of us have always wanted out of a next-generation Windows release: move all the cruft and compatibility to a glorified virtual machine, so that the remainder of the operating system can be modernised and improved without having to take compatbility into account. For now, Windows 10X seems focused on dual screen devices, but a lot of people in the know seem to think this is the actual future of Windows. Time will tell if this is actually finally really the case, but this does look promising.

Apple has $209 billion in cash on hand. California law requires Apple Inc. to pay its workers for being searched before they leave retail stores, the California Supreme Court decided unanimously Thursday. A group of Apple workers filed a class-action lawsuit against the tech giant, charging they were required to submit to searches before leaving the stores but were not compensated for the time those searches required. The U.S. 9th Circuit Court of Appeals, where the case is now pending, asked the California Supreme Court to clarify whether state law requires compensation. In a decision written by Chief Justice Tani Cantil-Sakauye, the court said an industrial wage order defines hours worked as “the time during which an employee is subject to the control of an employer, and includes all the time the employee is suffered or permitted to work, whether or not required to do so.” I repeat, Apple has $209 billion in cash on hand. Since it’s really hard to imagine how much even just one billion dollars really is, this demonstration should give you a very good idea. One billion dollars is way, way, way more than you think it is. Apple has 209 times that in cash on hand.

For more than half a century, governments all over the world trusted a single company to keep the communications of their spies, soldiers and diplomats secret. The company, Crypto AG, got its first break with a contract to build code-making machines for U.S. troops during World War II. Flush with cash, it became a dominant maker of encryption devices for decades, navigating waves of technology from mechanical gears to electronic circuits and, finally, silicon chips and software. But what none of its customers ever knew was that Crypto AG was secretly owned by the CIA in a highly classified partnership with West German intelligence. These spy agencies rigged the company’s devices so they could easily break the codes that countries used to send encrypted messages. The article is behind a paywall, sadly, but I figured it’s important enough to link to.

NEXTSPACE is a desktop environment that brings a NeXTSTEP look and feel to Linux. I try to keep the user experience as close as possible to the original NeXT’s OS. It is developed according to the “OpenStep User Interface Guidelines“. I want to create a fast, elegant, reliable, and easy to use desktop environment with maximum attention to user experience (usability) and visual maturity. In the future I would like to see it as a platform where applications will be running with a taste of NeXT’s OS. Core applications such as Login, Workspace, and Preferences are the base for future application development and examples of style and application integration methods. NEXTSPACE is not just a set of applications loosely integrated to each other. It is a core OS with frameworks, mouse cursors, fonts, colors, animations, and everything I think will help users to be effective and happy. KDE, GNOME, Xfce, and later MATE and Cinnamon have sucked up so much of the Linux desktop space that there’s very little room left for anything else. You’re either mainly a Qt desktop, or mainly a GTK+ desktop, and anything that isn’t based on either of those toolkits will either waste time recreating lots of wheels, or accept that half – or more – of your applications are Qt or GTK+-based, at which point the temptation to run one of the aforementioned desktop environments becomes quite strong. This project, while very welcome and having my full support and attention, will have a very hard time, but that’s not going to deter me from being hopeful against all odds. Reading through the documentation and descriptions, it does seem the developers have the right attitude. They’re not claiming to take on the other players – they just want to make something that appeals to and works for them.

A brand new version of the Plasma desktop is now available. In Plasma 5.18 you will find neat new features that make notifications clearer, settings more streamlined and the overall look more attractive. Plasma 5.18 is easier and more fun to use, while at the same time allowing you to be more productive when it is time to work. A lot welcome changes and polish, and I’m particularly pleased with the death of the insipid ‘cashew’ menu that resided in the top-right of the KDE desktop. You had to dive into the settings to remove it, but now it’s been replaced by a global edit mode that’s entirely invisible until you enable it, following in the footsteps of similar edit modes in Cinnamon and other user interfaces.

After about a year of development, the MATE Desktop team have finally released MATE 1.24. A big thank you to all contributors who helped to make this happen. This release contains plenty of new features, bug-fixes, and general improvements. That’s an impressive list. I prefer Cinnamon and GNOME 3 (after lots of tweaking!) over MATE, but I’m glad MATE exists as a no-nonsense, relatively conservative continuation of GNOME 2.

For the next couple (or maybe more) posts I’ll be explaining how WdFilter works. I’ve always been very interested on how AVs work (Nowadays I would say EDRs though) and their development at kernel level. And since, unfortunately I don’t have access to the source code of any, my only chance is to reverse them (or to write my own). And of course what a better product to check than the one written by the company who developed the OS. For those who don’t know, WdFilter is the main kernel component of Windows Defender. Roughly, this Driver works as a Minifilter from the load order group “FSFilter Anti-Virus”, this means that is attached to the File System stack (Actually, quite high – Big Altitude) and handles I/O operations in some Pre/Post callbacks. Not only that, this driver also implements other techniques to get information of what’s going on in the system. The goal of this series of post is to have a solid understanding on how this works under the hood. Not for the fain of heart.

Microsoft has now started to show text ad for its new Chromium-based Edge in the all apps list. The ad, which shows up under ‘Suggested’ listing for Start menu, recommends using the new version of Microsoft Edge. Surprisingly, the ad is targeting Firefox users. If you have Firefox as your default browser, you might see the advertisement or suggestion in the Start menu. Depending on whether you’re actively using Firefox or other browsers, the recommendation may or may not show up. “Still using Firefox? Microsoft Edge is here,” the ad label reads and it includes a link to download Chromium-based browser. Don’t use operating systems like Windows or iOS which are nothing but bait-and-switch vessels for ads.

Of course, AT&T wasn’t the company that ended up bringing us most of the tech predicted in the “You Will” ads. But it did bring that tablet device to market. It’s called the EO Personal Communicator 440, and while not the first mass-manufactured tablet computer — that honor goes to the GRiDPad, a device sold by Radio Shack’s corporate parent Tandy — the EO is generally considered one of the first tablets with mobile connectivity. Released by AT&T in 1993, not long after the telecom giant bought a majority stake in its maker EO, it was a tantalizing glance into the future. Any article on the EO is an article I will post – I’m a simple man – but that website’s fonts and font colours give me a headache.

Glass is a simulated operating system user interface (UI) project and it is being made with Unity 2018.4. It is not a real OS, although everything in the package is functional and can be changed easily. Not really an operating system, of course, but still a fascinating project. It also highlights just how versatile modern game engines really are – this is the same engine some of my favourite modern cRPGs and Cities: Skylines are running on.

Windows 10 may now be essential but users new and old have had a rough ride in recent weeks. And it has just gotten a lot worse after a new, high-profile Windows 10 failure has left more questions than answers and some seriously angry users. The drama began yesterday as Windows 10 users suddenly found that Search was broken with a black bar showing where search results should be, even for those who tried to perform a local search of their files. This is the future of proprietary operating systems like Windows, macOS and iOS as their parent companies move towards services and subscription models. More and more, they’ll use their operating systems to push their services and subscriptions, to the detriment of the user experience. It’s been happening in Windows 10 for a few years now, and iOS, too, is riddled with ads for Apple’s services. And so, we arrive at the point where local file search breaks down due to server issues. What a time to be alive.

In our tests here (more in our benchmark database), AMD’s 3990X would get the crown over Intel’s dual socket offerings. The only thing really keeping me back from giving it is the same reason there was hesitation on the previous page: it doesn’t do enough to differentiate itself from AMD’s own 32-core CPU. Where AMD does win is in that ‘money is less of an issue scenario’, where using a single socket 64 core CPU can help consolidate systems, save power, and save money. Intel’s CPUs have a TDP of 205W each (more if you decide to use the turbo, which we did here), which totals 410W, while AMD maxed out at 280W in our tests. Technically Intel’s 2P has access to more PCIe lanes, but AMD’s PCIe lanes are PCIe 4.0, not PCIe 3.0, and with the right switch can power many more than Intel (if you’re saving 16k, then a switch is peanuts). We acknowledge that our tests here aren’t in any way a comprehensive test of server level workloads, but for the user base that AMD is aiming for, we’d take the 64 core (or even the 32 core) in most circumstances over two Intel 28 core CPUs, and spend the extra money on memory, storage, or a couple of big fat GPUs. Aside from the artificial maximum memory limitation – which AMD put in place to protect its own Epyc processors – the 3990X is simply a masterpiece. To be able to get 64 cores and 128 threads for a relatively mere $3990 is nothing short of stunning, and while few of us actually need a processor like that, the 3990X shines like the halo product that it is.

Alan Kay said: “Simple things should be simple, complex things should be possible”. This sentence was the inspiration for the founder of RT-Thread to stick to his beliefs. RT-Thread is an open source embedded real-time operating system, and this project started in 2006. I know you have no idea what RT-Thread is, but you are using an IoT OS system now, that’s where this article may be of interest. Let’s take a quick tour of RT-Thread. RT-Thread: background RT-Thread, short for Real Time-Thread, is, as its name implies, an embedded real-time multi-threaded operating system. One of its basic properties is to support multitasking. Allowing multiple tasks to run at the same time does not mean that the processor actually performs multiple tasks at the same time. In fact, a processor core can only run one task at a time. Every task is executed quickly, and through the task scheduler (the scheduler determines the sequence according to priority), the tasks are switched rapidly, which gives the illusion that multiple tasks are running at the same time. In the RT-Thread system, the task is implemented by threads. The thread scheduler in RT-Thread is the task scheduler mentioned above. RT-Thread is mainly written in C, making it easy to understand and easy to port. It applies object-oriented programming methods to real-time system design, making the code elegant, structured, modular, and tailorable. For resource-constrained Microcontroller Unit (MCU) systems, the NANO version of RT-Thread (tailored from the standard version of RT-Thread), which requires only 3KB of flash and 1.2KB of RAM, can be tailored with easy-to-use tools. For resource-rich IoT devices, RT-Thread can use the online software package management tool, together with system configuration tools, to achieve intuitive and rapid modular cutting, seamlessly import rich software feature packs, thus achieving complex functions like Android’s graphical interface and touch sliding effects, smart voice interaction effects, and so on. RT-Thread’s architecture RT-Thread is not only a real-time kernel, but also has a rich middle-tier component, as shown in the following figure. It includes: The kernel layer: RT-Thread kernel, the core part of RT-Thread, includes the implementation of objects in the kernel system, such as multi-threading and its scheduling, semaphore, mailbox, message queue, memory management, timer, etc.; libcpu/BSP (Chip Migration Related Files/Board Support Package) is closely related to hardware and consists of peripheral drivers and CPU transport. The components and service layer: Components are based on upper-level software on top of the RT-Thread kernel, such as virtual file systems, FinSH command-line interfaces, network frameworks, device frameworks, and more. Its modular design allows for high internal cohesion within the assembly and low coupling between components. The RT-Thread software package: A general-purpose software component running on the RT-Thread IoT operating system platform for different application areas, consisting of description information, source code or library files. RT-Thread provides an open package platform with officially available or developer-supplied packages that provide developers with a choice of reusable packages that are an important part of the RT-Thread ecosystem. The package ecosystem is critical to the choice of an operating system because these packages are highly reusable and modular, making it easy for application developers to build the system they want in the shortest amount of time. RT-Thread supports more than 174 software packages. RT-Thread has launched more than a decade ago, and this is the first time we make an official self-introduction to the world, especially at the beginning of 2020, it feels great! We welcome suggestions for RT-Thread, and you can feel free to contact us on Twitter or send us an e-mail. And if you have any great ideas, you are very welcome to contribute to our Github.

bww Bitwise works has released a port of GCC 9.2 compiler to OS/2 Warp, ArcaOS and eComStation. This is a new milestone for OS/2 software development that allows the community to port more open source software to this platform. The project port is available at github.

One of the great game industry battles of the turn of century was the standoff between Quake III Arena and Unreal Tournament. With both multiplayer focused first person shooters released just weeks apart from one another, that the two games would wind up going head to head was inevitable. If pressed I am always going to have to say I favour the former, but the remarkable thing for us Linux users is that, for a time, both games lived harmoniously under the same publisher. While Quake III Arena was granted its place in eternity when its source code was released in 2005, community support for Unreal Tournament was able to breathe some new life into the game, even with the limitations of the closed binary. Even a strong community can’t fix such problems.

Recently, Motherboard obtained a copy of the contract businesses are required to sign before being admitted to Apple’s IRP Program. The contract, which has not previously been made public, sheds new light on a program Apple initially touted as increasing access to repair but has been remarkably silent on ever since. It contains terms that lawyers and repair advocates described as “onerous” and “crazy”; terms that could give Apple significant control over businesses that choose to participate. Concerningly, the contract is also invasive from a consumer privacy standpoint. In order to join the program, the contract states independent repair shops must agree to unannounced audits and inspections by Apple, which are intended, at least in part, to search for and identify the use of “prohibited” repair parts, which Apple can impose fines for. If they leave the program, Apple reserves the right to continue inspecting repair shops for up to five years after a repair shop leaves the program. Apple also requires repair shops in the program to share information about their customers at Apple’s request, including names, phone numbers, and home addresses. Nobody should be surprised by this. The only reason Apple announced this half-hearted program in the first place is to try and take the wind out of the sails of right to repair legislation, which is being proposed all over the US (and beyond), and the terms of this contract only further confirm that. As for the privacy aspect and Apple wanting all that very private user information – if you still think Apple cares about privacy, you really haven’t been paying attention.

The biggest and boldest move in the Feb. 5 reorg being announced internally today involves the Windows Experience (client) and the hardware teams. Microsoft is going to roll up these two businesses into a single team, known as Windows and Devices — reporting to Chief Product Officer Panos Panay, I’ve confirmed with a person familiar with the changes who asked not to be named. The move takes effect on Feb. 25. This means even tighter integration between the people designing and building Surface devices and the people developing Windows. Panay is the driving force behind the Surface products, and those have been doing relatively well, so it makes sense to allow him to take a stab at the future of Windows.

China’s Xiaomi, Huawei Technologies, Oppo and Vivo are joining forces to create a platform for developers outside China to upload apps onto all of their app stores simultaneously, in a move analysts say is meant to challenge the dominance of Google’s Play store. I’m glad Android is open enough to allow alternative application stores to exist, but whether or not non-Chinese application makers would want to partake in a Chinese state-run application store effort is another issue altogether.

Just another heads up that kernel extensions on macOS will soon stop working. This has been known for a while, but you might not even know you’re using kernel extensions in the first place. System extensions on macOS Catalina (10.15) allow software like network extensions and endpoint security solutions to extend the functionality of macOS without requiring kernel-level access. At WWDC19, we announced the deprecation of kernel extensions as part of our ongoing effort to modernize the platform, improve security and reliability, and enable more user-friendly distribution methods. Kernel programming interfaces (KPIs) will be deprecated as alternatives become available, and future OS releases will no longer load kernel extensions that use deprecated KPIs by default. If you use macOS, run kextstat | grep -v com.apple to see how many third party kernel extensions you have running. Things like VirtualBox, controller support for Steam, DropBox, Little Snitch, and more all come with kernel extensions, so there’s definitely chances you might be running some without even realising it.

I suspect that Wacom doesn’t really think that it’s acceptable to record the name of every application I open on my personal laptop. I suspect that this is why their privacy policy doesn’t really admit that this is what that they do. I imagine that if pressed they would argue that the name of every application I open on my personal laptop falls into one of their broad buckets like “aggregate data” or “technical session information”, although it’s not immediately obvious to me which bucket. Does Wacom have any competitors? Can you even vote with your wallet, or is this yet another market that isn’t really a market at all?

So the Democratic party of Iowa tried to use an untested app to report caucus results during the Iowa primary caucus, and… It went as well as you’d expect. Digging deeper into the app, it should’ve been obvious this was never going to work. In this case, however, it looks like Shadow used a test platform for the app’s public distribution. Installing software through a test platform or sideloading onto your device manually both come with security risks, as app store review processes are designed to discover whether a piece of software is hiding malware or does something behind the scenes it’s not supposed to. In the event you do sideload an app or try installing an unofficial version, your smartphone typically warns you of the risks and asks if you want to proceed. It’s also a less stable model for deploying software at scale, which might explain the difficulty precinct chiefs had in downloading the program. The screenshot from Motherboard also shows that the app was distributed using the platform’s free tier and not its enterprise one. That means Shadow didn’t even pony up for the TestFairy plan that comes with single sign-on authentication, unlimited data retention, and end-to-end encryption. Instead, it looks like the company used the version of TestFairy anyone can try for free, which deletes any app data after 30 days and limits the number of test users that can access the app to 200. What an unmitigated disaster. We’re in 2020 right? Not in 1783?

With Google Takeout, you can download your data from Google apps as a backup or for use with another service. Unfortunately, a brief issue with the tool last November saw your videos in Google Photos possibly get exported to strangers’ archives. How does this even happen? Too bad companies like this have armies of lawyers and obtuse terms of service to hide behind – since software is a special little butterfly that isn’t held to the same standards as any other product we use – so nobody will ever be held accountable for this.

We’re now past Catalina’s midpoint: with four versions already released, there’s only three more to go before we prepare for the first release of 10.16. That’s a stark fact, that we’re now at the point where the more cautious should consider whether they’ll run 10.15. Unusually for macOS, there are many Mac users with Catalina-compatible Macs who are no more able to upgrade now than they were back in October. These include the many who still have to rely on 32-bit apps, and those whose Mac doesn’t start up from an SSD. There’s still a lot of trepidation about Catalina, even among the Apple faithful in popular podcasts like ATP.

The real reason for Britain’s nonexclusion of Huawei was kept under wraps by its government: fear of retaliation. After Brexit, London sees itself as dependent on Beijing’s goodwill. In an interview with the Global Times on Jan. 20, the Chinese ambassador to Britain made it clear that an exclusion of Huawei would severely damage economic and political relations. And for Johnson, the threats from Beijing—a government with expansive control over its national economy—were more credible than those of U.S. President Donald Trump’s administration. Of course, fear isn’t much of an appealing public justification, especially for someone such as Johnson, who wants to project the image of a fearless leader. That’s why the government has come up with an extensive technical justification for the decision—an explanation that’s full of contradictions. Wait, you mean to tell me that going alone instead of being part of the biggest trade and power block after the US opens you up to manipulation and spying by and subservience to the likes of China and Russia? This should make it clear to the US and the EU that the UK should not be trusted with intelligence data.

USB Implementers Forum, the support organization for the advancement and adoption of USB technology, today announced the publication of the USB4 specification, a major update to deliver the next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures. The USB4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel Corporation to the USB Promoter Group. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols. As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4 specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected. How many years until USB4 (or later) replaces HDMI and DisplayPort? Since everything is data packets now – analog is a thing of the past – do we really need to have separate video cables? I’d love to one day build a PC that just has an array of USB-C ports on the back, with the ability to plug anything – monitor, keyboard, mouse, serial port adapter for the Windows CE mini laptop I’ve been craving to buy for ages, you know, the usual stuff – into any of the ports. One can dream.

System calls are a way for unprivileged, user applications to request services from the kernel. In the RISC-V architecture, we invoke the call using the ecall instruction. This will cause the CPU to halt what it’s doing, elevate privilege modes, and then jump to whatever function handler is stored in the mtvec (machine trap vector) register. Remember, this is the “funnel” where all traps are handled, including our system calls. We have to set up our convention for handling system calls. We can use a convention that already exists, so we can interface with a library, such as newlib. But, let’s make this ours! We get to say what the system call numbers are, and where they will be when we execute a system call. This is part 7 in a long series about writing a RISC-V operating system in Rust.

EU lawmakers overwhelmingly called on Thursday for rules to establish a common charger for all mobile device makers across Europe, a drive that iPhone maker Apple has criticised. Members of the European Parliament voted by 582-40 for a resolution urging the European Commission, which drafts EU laws, to ensure that EU consumers are no longer obliged to buy new chargers with each new device. This story is a case of government regulation done extremely well. This whole process started with a voluntary agreement in the industry to standardise on one charger and port, and if they failed, the EU would step in and enforce it by law. This agreement has worked out quite well – first micro USB, now USB-C. However, one popular phone maker decided to not adhere to the agreement, and so, more than ten years after the agreement, and thus ample time for this phone maker to follow suit, the EU will now have to step in. Apple has already moved all of its devices to USB-C, save for one – the iPhone. Now they won’t have much of a choice but to follow along. Much like with RoHS, the rest of the world has only benefited from this push for a charging standard, as anyone who remembers the feature phone and PDA days can only attest to (you should see my mutually incompatible collection of just PDA chargers – I must have dozens of them!). And no, this won’t stifle innovation. This whole process is done in collaboration with the industry and standards bodies, so if newer options come along that the sector wants to standardise on, they can – just as they did with the move from micro USB to USB-C. Apple will just have to suck it up – maybe while they’re at it, they can finally make a charging cable that doesn’t suck?

Two-factor security is a basic requirement these days if you want to take your digital responsibilities seriously, but some hardware lacks the sort of public documentation that some privacy advocates feel is truly necessary to provide ideal security. Open source enthusiasts will be glad to hear that Google has just announced the release of OpenSK, an open-source implementation for security keys, supporting both FIDO U2F and FIDO2. I’ve always loved the idea of carrying a small piece of hardware to serve as an authentication device, but I’ve never done any serious research into the concept. Of course, and such system would need to be 100% open source, so maybe OpenSK is a contender.

Under hard time pressure, the ground had to quickly figure out what was wrong and devise a workaround. What they came up with was the most brilliant computer hack of the entire Apollo program, and possibly in the entire history of electronic computing. To explain exactly what the hack was, how it functioned, and the issues facing the developers during its creation, we need to dig deep into how the Apollo Guidance Computer worked. Hold onto your hats, Ars readers—we’re going in. Amazing story.

IBM named Arvind Krishna as chief executive officer, replacing longtime CEO Virginia Rometty. Krishna is currently the head of IBM’s cloud and cognitive software unit and was a principal architect of the company’s purchase of Red Hat, which was completed last year. Rometty, 62, will continue as executive chairman and serve through the end of the year, when she will retire after almost 40 years with the company, IBM said in a statement Thursday. Good luck to the man, I guess. IBM isn’t exactly the most exciting company in the world.

Today, I watched a SpaceX Falcon 9 rocket leave Cape Canaveral and deliver 60 small Starlink satellites to Low Earth Orbit (LEO) on the Starlink L3 mission. For those not with us last week, SpaceX has a subsidiary, known as Starlink, which is presently endeavoring to blanket the majority of the inhabited latitudes of Earth with orbiting satellites to provide wireless internet access and private-line communications services. This is a Big Deal, the consequences of which I will explain momentarily. But first, some background. Out of all of Elon Musk’s crazy projects, this is the only one that interests me. This project can have huge consequences.

The iPad is now ten years old, and people still have to write articles about how, no, really, you can do real work on an iPad! In 1994, ten years after the Mac was originally introduced, I got my first computer, a Performa 450. Nobody wrote any articles about how, actually, real work on a Mac is possible. Everybody who had a Mac used it for real work. There was no need to write articles about how you could use Macs for real work, because for Macs, it was – and still is – actually true. There are countless people who work on iPads, but the central thread in almost all of the articles and stories about these people is that they involve countless, extensive compromises to make it work – whether that’s resorting to a PC for a lot of tasks, or using complex, hacky Shortcuts to accomplish things any other computer can do without you even thinking about it. I see no reason an iPad can’t be a full, proper computer that can replace many a laptop and desktop, but Apple will need to put some serious weight behind iOS as a platform. The hardware is more than capable – it’s the software that holds it back. The fact we’re ten years into this thing and there’s still no Xcode for iPad tells you all you need to know about how Apple sees the iPad.

This Businessweek article isn’t new. It’s from August 2019. But it has some great data visualizations that I thought our readers would be interested in, looking at technology adoption in general and mobile OS market share in particular, starting with this one:

There was a time when Thunderbird’s future was uncertain, and it was unclear what was going to happen to the project after it was decided Mozilla Corporation would no longer support it. But in recent years donations from Thunderbird users have allowed the project to grow and flourish organically within the Mozilla Foundation. Now, to ensure future operational success, following months of planning, we are forging a new path forward. Moving to MZLA Technologies Corporation will not only allow the Thunderbird project more flexibility and agility, but will also allow us to explore offering our users products and services that were not possible under the Mozilla Foundation. The move will allow the project to collect revenue through partnerships and non-charitable donations, which in turn can be used to cover the costs of new products and services. Thunderbird’s focus isn’t going to change. We remain committed to creating amazing, open source technology focused on open standards, user privacy, and productive communication. The Thunderbird Council continues to steward the project, and the team guiding Thunderbird’s development remains the same. I’m glad Thunderbird and its users found a way forward for the application, but I’ve never been a fan of these complex, overloaded e-mail/groupware applications like Thunderbird, Evolution, and Kmail. I use Geary because it focuses on one thing and does it well – e-mail – and it doesn’t try to also do all sorts of stuff I don’t want an e-mail client to do. As a side note, KDE could really use a Geary-like simple e-mail client – because Kmail is not in a great state.

KnightOS is an operating system I started writing about 10 years ago, for Texas Instruments line of z80 calculators — the TI-73, TI-83+, TI-84+, and similar calculators are supported. It still gets the rare improvements, but these days myself and most of the major contributors are just left with starry eyed empty promises to themselves that one day they’ll do one of those big refactorings we’ve been planning… for 4 or 5 years now. Still, it was a really interesting operating system which was working under some challenging constraints, and overcame them to offer a rather nice Unix-like environment, with a filesystem, preemptive multiprocessing and multithreading, assembly and C programming environments, and more. The entire system was written in handwritten z80 assembly, almost 50,000 lines of it, on a compiler toolchain we built from scratch. The things people can squeeze out of these limited devices astounds me every single time.

I’ll be setting my system up on a Windows machine, but you could just as easily set it up on a macOS or Linux machine. When I first attempted this install, I used VMware Workstation 14 Pro for Windows. After going through most of the installation process I couldn’t get OpenStep in to a color screen mode no matter how much I tried. I eventually found out that VMware Workstation doesn’t support the proper VESA display modes, and try as you might you’ll get an error on boot that says “VESA Mode Not Supported.” Fortunately, Virtual Box – which is cross-platform between Windows, macOS, and Linux and completely free – does support the proper VESA mode and works great for the installation of OpenStep. Still, there are some quirks when setting up your VirtualBox VM initially. The VM must have 1 processor with 1 core, 64MB of RAM, and a 2.0GB hard disk on an IDE controller. You will need to configure one IDE CD-ROM drive and one floppy drive. The hard drive must be at IDE 0:0 (Primary Master), and the CD-ROM drive must be at IDE 0:1 (Primary Slave). You will have to edit the properties of the VM upon creation to ensure you adhere to these standards. All other default options of the VM during the creation wizard can be left alone. NextStep is a lot of fun to explore and play around with, since you can clearly see the early days of Mac OS X in there, for obvious reasons. It’s definitely worth it to set an evening apart and follow this tutorial.

An antivirus program used by hundreds of millions of people around the world is selling highly sensitive web browsing data to many of the world’s biggest companies, a joint investigation by Motherboard and PCMag has found. Our report relies on leaked user data, contracts, and other company documents that show the sale of this data is both highly sensitive and is in many cases supposed to remain confidential between the company selling the data and the clients purchasing it. The documents, from a subsidiary of the antivirus giant Avast called Jumpshot, shine new light on the secretive sale and supply chain of peoples’ internet browsing histories. They show that the Avast antivirus program installed on a person’s computer collects data, and that Jumpshot repackages it into various different products that are then sold to many of the largest companies in the world. Some past, present, and potential clients include Google, Yelp, Microsoft, McKinsey, Pepsi, Sephora, Home Depot, Condé Nast, Intuit, and many others. Some clients paid millions of dollars for products that include a so-called “All Clicks Feed,” which can track user behavior, clicks, and movement across websites in highly precise detail. Is anybody really surprised by this? Antivirus companies have been scammers for a long time now, spreading fear and anxiety amongst primarily less knowledgeable users, tricking and scamming them into paying exorbitant amounts of money for tools that are not needed, do not work, slow computers down, and in many cases, actively harm operating systems. Of course, with these programs running with unparalleled access to many Windows machines, we all knew antivirus companies would resort to selling user data to make an extra buck, sinking even deeper. You don’t need anything more than what your operating system provides, whether you use Windows, Linux, macOS, Android, or iOS.

Even though regular, free Windows 7 support has ended only a few days ago, Microsoft has already been forced to release a regular update to fix a bug. We reported earlier that Windows 7 users were complaining of their wallpaper being replaced by black screens when they install the important KB4534310 and KB4534314 updates for Windows 7. The wallpaper bug affected all the Windows 7 users who use stretch option while setting up wallpapers. Microsoft later confirmed that it was indeed a bug but said the company would fix it only for customers who purchased ESU, i.e. organizations. However, it looks like the company has gone back on its word and decided to release an update for everyone. The best laid plans.

Starting now, Microsoft will roll out their new Chromium-based Edge browser to their millions of Windows 10 users. And this will also mark the end of an era. The era of the Trident-Engine. But hadn’t the Trident era already ended when Edge appeared? Not really. This is a very deep look at the Trident engine. Goodness.

A couple of weeks back, Google redesigned the search results for its desktop website. According to the firm, the new layout was meant to mimic the ordering of search results on the mobile version of the website. Most significantly, the changes allowed the inclusion of favicons next to display results and the removal of color overlays. This meant that advertisements and traditional search results were displayed inline with little to distinguish between the two. And now Google is backpedaling. As a DDG user, this thing kind of passed me by, but upon checking Google, I have to say I agree that this feels so off. You’d think adding favicons to search results wouldn’t make a big difference, but it really does – and not for the better.

A lightweight macOS window and app manager scriptable with JavaScript. You can also easily use languages which compile to JavaScript such as CoffeeScript. Phoenix aims for efficiency and a very small footprint. If you like the idea of scripting your own window or app management toolkit with JavaScript, Phoenix is probably going to give you the things you want. With Phoenix you can bind keyboard shortcuts and system events, and use these to interact with macOS. Pretty cool.

I wonder about the approach Purism took with the Librem 5. The company chose to do everything all at once by building a new smartphone OS and a new hardware supply chain. For a customer receiving a Librem 5 today, you’re getting an unfinished operating system and rough, gen-one open source hardware. That’s a bunch of compromises to accept for $750. A more reserved approach would have been to build an open source GNU/Linux-based OS on closed source hardware first and then make the difficult jump to custom hardware when the OS was in a more complete state. The Librem 5 is a tough sell, even for people who value the open source nature of the device. That’s simply too much money for such an outdated, unfinished device.
