From the team that has brought PC and Console gamers the latest in graphics innovation for nearly 25 years, we are beyond pleased to bring gamers DirectX 12 Ultimate, the culmination of the best graphics technology we’ve ever introduced in an unprecedented alignment between PC and Xbox Series X. When gamers purchase PC graphics hardware with the DX12 Ultimate logo or an Xbox Series X, they can do so with the confidence that their hardware is guaranteed to support ALL next generation graphics hardware features, including DirectX Raytracing, Variable Rate Shading, Mesh Shaders and Sampler Feedback. This mark of quality ensures stellar “future-proof” feature support for next generation games! That’s some Vista-era name right there.
Sony has broken its silence. PlayStation 5 specifications are now out in the open with system architect Mark Cerny delivering a deep dive presentation into the nature of the new hardware and the ways in which we should expect a true generational leap over PlayStation 4. Digital Foundry had the chance to watch the lecture a couple of days ahead of time and had the opportunity to talk to Cerny in more depth afterwards about the nature of the custom PlayStation hardware and the philosophy behind its design. And just as with the Xbox Series X, specifications are meaningless without the games to back them up.
Apple today released the golden master version of iOS and iPadOS 13.4, the latest major updates to the iOS 13 operating system that was released in September. The iOS and iPadOS 13.4 GMs come after a little over a month of beta testing. The biggest new feature – which is accompanied by new iPad Pro devices and a keyboard with trackpad – is mouse support in iPadOS. The cool thing here is that Apple’s iOS cursor – a dot, so not an arrow – is a thing of marvel, and it does some really neat tricks that you won’t find anywhere else. When you hover over a tappable button, the pointer disappears and instead you get a hover-state highlight around the button. Hover over an app icon in the Dock or on your homescreen, and instead of seeing the mouse pointer on top of the icon, you see a highlight around the icon, much like the way icons are popped on tvOS. When text editing, the cursor changes to an I-beam, of course, but it’s an all-new I-beam cursor, not the one you get in iOS while using the on-screen keyboard as a virtual trackpad (after a tap-and-hold on the spacebar or two-finger tap-and-drag on the key area). This new I-beam cursor is smart. It adjusts to the size of the text you’re editing — if you’re editing 16-point text you’ll get a smaller cursor; if you’re editing 48-point text you’ll get a larger cursor. (Lo these 35+ years after the original Macintosh, it suddenly strikes me as a bit silly that the I-beam cursor stays small even when editing very large text.) The new iPadOS I-beam cursor also is aware of where lines are in text fields, and “snaps” to the line. There seem to be a lot of small little niceties here that seem so obvious once you see them in action. It’s really cool stuff, and I can’t wait to try it out.
Arm server chip upstart Ampere Computing made a big splash with its 80-core “Quicksilver” Altra processor two weeks ago, and Marvell, which is the volume leader in Arm server chips with its “Vulcan” ThunderX2 processors (largely inherited from its acquisition of Broadcom’s Arm server chip assets), is hitting back with some revelations about its future “Triton” ThunderX3 chip and its roadmap out beyond that. Competition in the ARM server space is really heating up.
Due to adjusted work schedules at this time, we are pausing upcoming Chrome and Chrome OS releases. Our primary objectives are to ensure they continue to be stable, secure, and work reliably for anyone who depends on them. We’ll continue to prioritize any updates related to security, which will be included in Chrome 80. Basically, Google wants to ensure the stability of Chrome and Chrome OS now that a lot of people are working from home due to the pandemic. Good call.
NsCDE is a retro but powerful (kind of) UNIX desktop environment which resembles CDE’s look and (partially feel), but with a more powerful and flexible beneath-the-surface framework, more suited for 21st century UNIX-like and Linux systems and user requirements than original CDE. NsCDE can be considered as something between a heavyweight FVWM theme on steroids, combined with a couple of other free software components and custom FVWM applications and heavy configurations. NsCDE can be considered as lightweight hybrid desktop environment. Be still, my beating heart.
AMD’s laptop offerings haven’t been amazing these past few years, but with the unveiling of their 4000 processors, that’s finally going to change. All that seems set to change. Fast forward to 2020, and notebook users are eagerly awaiting the arrival of products based on AMD’s latest Ryzen Mobile 4000 series processors, which combine up to eight Zen 2 cores and upgraded Vega graphics into a small CPU for the notebook market. AMD has already made waves with its Zen 2 cores in the desktop and enterprise space, and the company has already announced it plans to put eight of those cores, along with a significantly upgraded graphics design, into a processor that has a thermal design point of 15 W. These 15 W parts are designed for ultraportable notebooks, and AMD has a number of design wins lined up to show just how good an AMD system can be. The same silicon will also go into 45 W-class style notebooks, with a higher base frequency. These parts are geared more towards discrete graphics options, for gaming notebooks or more powerful business designs. The gaming market (at 45 W), the commercial market (15W to 45W) and the ultraportable market (15 W) are where AMD is hoping to strike hardest with the new hardware. I can’t wait for serious competition to Intel in the laptop space. It’s sorely needed.
Microsoft is revealing the full specs for its Xbox Series X console today, and it includes support for removable storage and much faster load times for games. The software giant will be using a custom AMD Zen 2 CPU with eight cores clocked at 3.8GHz each, a custom AMD RDNA 2 GPU with 12 teraflops and 52 compute units clocked at 1.825GHz each. This is all based on a 7nm process and includes 16GB of GDDR6 RAM with a 1TB custom NVME SSD storage drive. Microsoft is using two mainboards on this Xbox Series X compact design, and the entire unit is cooled through air being pulled in from the bottom and pushed out at the top via a 130mm fan. That’s some serious firepower, but the Xbox One series didn’t lack power either, yet lost the market share battle to the PS4 without putting up much of a fight. Firepower means nothing without the games to back it up, and that’s where the Xbox One simply failed to deliver. Show us the games, because without those, all this hardware is useless. That being said, I’ve always had a soft sport for chimney-like computer designs since the PowerMac G4 Cube, and this fits right in there. Perhaps not the most practical design, but it sure does stand out.
This blog post examines a 1980s chip used in a Soyuz space clock. The microscope photo below shows the tiny silicon die inside the package, with a nice, geometric layout. The silicon appears pinkish or purplish in this photo, while the metal wiring layer on top is white. Around the edge of the chip, the bond wires (black) connect pads on the chip to the chip’s pins. The tiny structures on the chip are resistors and transistors. That’s just cool.
Microsoft has launched a new website for the Windows UI Library (WinUI) that provides more information on the various advantages of the modern libraries for the development of Windows. WinUI allows developers to access and use Fluent controls, styles, and other UWP XAML controls via NuGet packages. While earlier versions of the WinUI focused on UWP, the Redmond giant has been expanding the framework. The preview version of WinUI 3.0 brought with it support for the full Windows 10 native UI platform. The extended scope of the platform meant that developers could use WinUI XAML with their existing WPF, Windows Forms, and Win32 applications. The website terms WinUI as the modern native UI platform of Windows. Will this be the one that sticks?
Thanks to Dutch technology website Tweakers’ Arnoud Wokke for pointing this one out before any of the major sites have – Apple has been fined for 1.1 billion euros by the French competition authority for anti-competitive practices. You can read the announcement in French, too. The short of it is that between 2005 and 2013, Apple primarily sold its products in France through two specific wholesalers, who have also been fined, and the three of them agreed not to compete, limiting competition. Apple also imposed pricing upon its independent Authorised Resellers and Premium Resellers, making it impossible for them to compete on price. In addition, Apple also limited the supply given to these resellers compared to its own stores, which further limited the their ability to function. What’s interesting here is that this is Apple’s modus operandi all over Europe and the rest of the world, so it wouldn’t surprise me if other EU countries will work off of this ruling in the near future. This kind of illegal behaviour by massive corporations has gone unpunished for long enough, and it’s high time serious punishments are doled out. Good on the French authorities for this one.
We’re once again approaching that time of the year when Microsoft releases a new feature update to Windows 10. In line with the version numbering scheme we’ve been seeing, this update is currently known as Windows 10 version 2004, or 20H1, because it’s being released in the first half of the year. While we did get a feature update in the second half of 2019, there was only a very small number of additions, and those additions were also minor in nature. It was more about refining the previous update than making significant leaps forward. Surprisingly, even though version 2004 is a more significant feature update, it’s one of the smaller ones, despite having a longer period of testing with Insiders than what we’ve seen before. With that being said, there are still a few changes and improvements to many parts of the experience, and if you want to know all about it, we’ve compiled this list for you. Let’s get started. There’s some nice additions in there, but nothing earth-shattering or game-changing. Windows 10 is five years old now, and it feels like the model of frequent feature updates (instead of monolithic Windows releases and the occasional service pack) just isn’t really moving the needle.
We already covered earlier articles in this series, but I want to highlight this one too, because it covers one of the most unique consoles ever developed – the Atari Jaguar. The designers of the Jaguar departed from the traditional architecture where one CPU drives fixed-pipeline audio and graphics chips as we saw earlier in the series with the SNES and Genesis. If we find a Motorola 68000 like in the Atari, Amiga, and Genesis (albeit running at 13.295 Mhz) and a sprites engine (called Object), there is also two 32-bit RISC processors running at 26.59 MHz called TOM and JERRY. The Jaguar is wild.
Microsoft said this week that it will support Visual Basic on .NET 5.0 but will no longer add new features or evolve the language. “Starting with .NET 5, Visual Basic will support Class Library, Console, Windows Forms, WPF, Worker Service, ASP.NET Core Web API … to provide a good path forward for the existing VB customer who want to migrate their applications to .NET Core,” the .NET team wrote in a post to the Microsoft DevBlogs. “Going forward, we do not plan to evolve Visual Basic as a language … The future of Visual Basic … will focus on stability, the application types listed above, and compatibility between the .NET Core and .NET Framework versions of Visual Basic.” Alright then.
Microsoft today announced that Co-Founder and Technology Advisor Bill Gates stepped down from the company’s Board of Directors to dedicate more time to his philanthropic priorities including global health, development, education, and his increasing engagement in tackling climate change. He will continue to serve as Technology Advisor to CEO Satya Nadella and other leaders in the company. Microsoft is in a pretty good spot, so Gates’ company seems to be in good hands.
Google is not working with the US government in building a nationwide website to help people determine whether and how to get a novel coronavirus test, despite what President Donald Trump said in the course of issuing an emergency declaration for the coronavirus pandemic. Instead, a much smaller trial website made by another division of Alphabet, Google’s parent company, is going up. It will only be able to direct people to testing facilities in the Bay Area. People are dying, and the administration of the most powerful and important country in the world is lying to its citizens left, right, and centre. What a joke.
seL4 has been our team’s greatest achievement, but it didn’t fall out of the sky: it was the result of 15 years of research, and has evolved further for the past 10 years. From the beginning, the design of seL4 has been driven by a number of principles. But a recent internal discussion about some fine points of the spec (as well as some discussions with externals) reminded me that some of these principles are in the minds of the designers but not really documented. This can lead to people (internal as well as external to Trustworthy Systems) arguing for APIs that are not in the spirit of seL4. Hence I’ll try to write up these principles. Articles like these are rare.
In the previous installment of this three-part series, we took a look at the reasons why having truly open source-friendly Linux-based phones are not only a good thing to have but are also necessary to shake up things in the mobile space. The idea, of course, isn’t new and goes as far back as the OpenMoko community-driven project and even the mostly-but-not-totally open source Nokia N900 and N9. Those days are long gone, however, and the smartphone industry has changed drastically over the last decade and so have the attempts at making Linux phones. In this part, we take stock of the options that are currently available not just to Linux enthusiasts but to privacy and freedom-loving people as well. I’d love to have a mobile operating system based on Linux that isn’t Android, but it seems like all the options still have a long, long way to go.
Today KaiOS Technologies, maker of KaiOS, the leading mobile operating system for smart feature phones, and Mozilla, developer of one of the world’s leading web browsers, announced a partnership to enhance the Gecko engine for KaiOS, enabling a more diverse and open mobile internet for users around the world. Kai’s engineering expertise and Mozilla’s software support together will ensure future versions of Gecko are compatible with KaiOS-enabled devices and their web-based resources. I really want a KaiOS device to give the platform a proper test. It seems like such an elegant midway point between the cell phone of yore and modern smartphones.
We’ve known that Intel’s P-State Linux CPU frequency scaling driver in general can be a bit quirky and especially so when dealing with Intel integrated graphics where the iGPU and CPU share the same power envelope. This has been shown with examples like using the “powersave” governor to boost iGPU performance while discrete graphics owners are generally best off switching over to the “performance” governor. As the latest though on helping the iGPU front with P-State, there is a new patch series talking up big gains in performance and power efficiency. Francisco Jerez of Intel’s open-source driver team sent out a set of ten patches today working on GPU-bound efficiency improvements for the Intel P-State driver. This is a very welcome patchset, since the interplay between Intel processor and Intel integrated GPU isn’t exactly optimal, as we’ve talked about before.
