ARM has introduced the Neoverse N1 platform, the blueprint for creating power-efficient processors licensed to institutions that can customize the original design to meet their specific requirements. Ampere licensed the Neoverse N1 platform to create the Ampere Altra, a processor that allows companies that own and manage their own fleet of servers, like ourselves, to take advantage of the expanding ARM ecosystem. We have been working with Ampere to determine whether Altra is the right processor to power our first generation of ARM edge servers. The AWS Graviton2 is the only other Neoverse N1-based processor publicly accessible, but only made available through Amazon’s cloud product portfolio. We wanted to understand the differences between the two, so we compared Ampere’s single-socket server, named Mt. Snow, equipped with the Ampere Altra Q80-30 against an EC2 instance of the AWS Graviton2. Cloudflare compared these two ARM server platforms and benchmarked them, and they give a ton of detail about them, too. Give it a few more years, and ARM will be a decidedly normal sight within data centres all over the world.
Another month, another Haiku activity report. It was less busy this month, so there’s nothing that really jumps out at me as a major fix or improvement. I’m going to highlight the first listed item, since fixes in software delivery are always welcome. Andrew Lindesay continues his work on cleaning HaikuDepot sources and removing a custom-made List class to use standard (BeAPI and C++ stl) containers. There were some regressions in the process, that were found and identified. Haiku’s steady stream of fixes and improvements continues.
Google Chrome version 89 began rolling out to users in the stable channel on March 2 and should be on most people’s machines by now. The new build offers significant memory savings on 64-bit Windows platforms thanks to increased use of Google’s PartitionAlloc memory allocator. On macOS, Chrome 89 plays catch-up and gets closer to the performance of the flagship Windows builds. I feel like we get these reports and promises about Chrome’s performance every few months, yet Chrome keeps being the butt of jokes regarding its resource usage, especially on the Mac. Maybe this round will yield tangible improvements.
The KaiStore team keeps up the momentum with another set of updates that make it easier to find the apps you’re looking for and enhance the UX experience as a whole. We don’t talk much about KaiOS on OSNews, which is a shame – it’s an offshoot of Firefox OS, and a massive success on phones that blends smartphone and feature phone functionality into one platform. This isn’t a big news item or anything, but ran across it and feel some attention for this platform is more than warranted.
This article is a guide for achieving a full-as-possible Wayland setup on Arch Linux. This guide does exactly what it says – it helps you set up a complete Arch Linux installation that is as Wayland as possible.
This afternoon, I was updating the streaming apps on my 2020 LG CX OLED TV, something I do from time to time, but today was different. Out of nowhere, I saw (and heard) an ad for Ace Hardware start playing in the lower-left corner. It autoplayed with sound without any action on my part. Now I’m fully aware that it’s not unusual to see ads placed around a TV’s home screen or main menu. LG, Samsung, Roku, Vizio, and others are all in on this game. We live in an era when smart TVs can automatically recognize what you’re watching, and TV makers are building nice ad businesses for themselves with all of the data that gets funneled in. But this felt pretty egregious even by today’s standards. A random, full-on commercial just popping up in LG’s app store? Is there no escape from this stuff? We’re just going to cram ads into every corner of a TV’s software, huh? Imagine if an autoplay ad started up while you were updating the apps on your smartphone. People want cheap TVs, so people get cheap TVs – warts and all. Someone should set up a website and list TVs that are “safe to buy” and do not contain or display any ads. Of course, this still doesn’t solve the issue of “smart” TVs being security nightmares, but it’d be a step.
Chromebooks launched 10 years ago with a vision to rethink computing by designing a secure, easy-to-use laptop that becomes faster and more intelligent over time. As more and more people began using devices running Chrome OS, we evolved and expanded the platform to meet their diverse needs. Today, Chrome OS devices do everything from helping people get things done to entertaining them while they unwind. But we want to do more to provide a powerfully simple computing experience to the millions of people who use Chromebooks. We’re celebrating 10 years of Chromebooks with plenty of new features to bring our vision to life. It’s hard to imagine it’s already been ten years. Chromebooks are definitely a big success, and I’d love to finally sit down and properly review a Chromebook. I’ve barely even used one, and I want to know what it’s really like to live in a always-online world.
Rust/coreutils is now available in Debian, good enough to boot a Debian with GNOME, install the top 1000 packages, build Firefox, the Linux Kernel and LLVM/Clang. Even if I wrote more than 100 patches to achieve that, it will probably be a bumpy ride for many other use cases. Fascinating initiative, and a hell of a lot of work. Rust seems to be gaining ground left, right, and centre.
This is an early attempt at microarchitecture documentation for the CPU in the Apple M1, inspired by and building on the amazing work of Andreas Abel, Andrei Frumusanu, @Veedrac, Travis Downs, Henry Wong and Agner Fog. This documentation is my best effort, but it is based on black-box reverse engineering, and there are definitely mistakes. No warranty of any kind (and not just as a legal technicality). To make it easier to verify the information and/or identify such errors, entries in the instruction tables link to the experiments and results (~35k tables of counter values). Amazing work, but the fact this kind of work is even needed illustrates just how anti-consumer these new Macs really are.
What a long, strange trip it’s been. MIPS Technologies no longer designs MIPS processors. Instead, it’s joined the RISC-V camp, abandoning its eponymous architecture for one that has strong historical and technical ties. The move apparently heralds the end of the road for MIPS as a CPU family, and a further (slight) diminution in the variety of processors available. It’s the final arc of an architecture. Interestingly, MIPS and RISC-V share an architect in Dave Patterson, and MIPS could be seen as an ancestor of RISC-V.
Thanks to Twitter, here’s an interesting footnote in computing history. As A/UX development was winding down, Apple was working on another project called the Macintosh Application Environment. This was an emulator that allowed users to run Mac software under Sun’s Solaris or Hewlett Packard’s HP-UX. A great deal of A/UX technology went into the design of this ill-fated product. This page is a pictorial tribute to the Macintosh Application Environment, running under Solaris 8 on an Ultra 10 workstation. If you want to try the MAE, you’ll need a Sun box running Solaris 9 or below – The software does not appear to work under Solaris 10. This is absolutely fascinating, and I had no idea this existed.
Our results clearly show that Intel’s performance, while substantial, still trails its main competitor, AMD. In a core-for-core comparison, Intel is slightly slower and a lot more inefficient. The smart money would be to get the AMD processor. However, due to high demand and prioritizing commercial and enterprise contracts, the only parts readily available on retail shelves right now are from Intel. Any user looking to buy or build a PC today has to dodge, duck, dip, dive and dodge their way to find one for sale, and also hope that it is not at a vastly inflated price. The less stressful solution would be to buy Intel, and use Intel’s latest platform in Rocket Lake. This is Intel’s 10nm design backported to 14nm. It’s not great, and lags behind AMD substantially, but with the chip shortage, it’s probably the only processor you can get at a halfway reasonable price for the foreseeable future.
That’s one hell of a number of games. Proton has been receiving many updates in the past few months as well, with the introduction of the Soldier Linux runtime container and Proton Experimental on top of the regular Proton releases. We are still getting about 100 new titles working flawlessly (according to user reports) on a monthly basis, which is a very healthy and steady growth. Another point is the percentage of Windows games working out of the box in Proton over time. The number has been close to 50% since for a long time and seems to be fairly stable. Proton is one of the biggest things to happen to desktop Linux in over a decade – or more.
This article takes a look at what’s changed in the Android ecosystem for audio developers recently, the audio latency of popular Android devices, and discusses Android’s suitability for real-time audio apps. An infamous weak point for Android.
On OSNews we recently reported on how Google plans to remove support for third-party cookies. Many have seen this as offering a privacy boost for users, leading to a better Web where targeted ads based on web-browser behaviour are a thing of the past. The EFF takes a different view. Google is leading the charge to replace third-party cookies with a new suite of technologies to target ads on the Web. And some of its proposals show that it hasn’t learned the right lessons from the ongoing backlash to the surveillance business model. This post will focus on one of those proposals, Federated Learning of Cohorts (FLoC), which is perhaps the most ambitious—and potentially the most harmful. FLoC is meant to be a new way to make your browser do the profiling that third-party trackers used to do themselves: in this case, boiling down your recent browsing activity into a behavioral label, and then sharing it with websites and advertisers. The technology will avoid the privacy risks of third-party cookies, but it will create new ones in the process. It may also exacerbate many of the worst non-privacy problems with behavioral ads, including discrimination and predatory targeting.
The great unicorn of software development is to have one language and framework that enables devs to code an app once and run it on any operating system and any type of device. Flutter has been aiming to do this since its inception, and today it gets quite a bit closer to that goal with the announcement of Flutter 2. The latest major update brings major enhancements for mobile platforms, adds support to desktop, and massively extends its capabilities on the web — among other things. Does anyone here have experience with Flutter? It seems like it’s gaining some steam judging by the increase in news stories about it recently.
Genode 21.02 stays close to the plan laid out on our road map, featuring a healthy dose of optimizations, extends the framework’s ARM SoC options, and introduces three longed-for new features. Tons of new features and improvements in this Genode release.
Huge news from Google, who announced today that they are going to stop using your web browsing behaviour to display targeted advertisements. It’s difficult to conceive of the internet we know today — with information on every topic, in every language, at the fingertips of billions of people — without advertising as its economic foundation. But as our industry has strived to deliver relevant ads to consumers across the web, it has created a proliferation of individual user data across thousands of companies, typically gathered through third-party cookies. This has led to an erosion of trust: In fact, 72% of people feel that almost all of what they do online is being tracked by advertisers, technology firms or other companies, and 81% say that the potential risks they face because of data collection outweigh the benefits, according to a study by Pew Research Center. If digital advertising doesn’t evolve to address the growing concerns people have about their privacy and how their personal identity is being used, we risk the future of the free and open web. That’s why last year Chrome announced its intent to remove support for third-party cookies, and why we’ve been working with the broader industry on the Privacy Sandbox to build innovations that protect anonymity while still delivering results for advertisers and publishers. Even so, we continue to get questions about whether Google will join others in the ad tech industry who plan to replace third-party cookies with alternative user-level identifiers. Today, we’re making explicit that once third-party cookies are phased out, we will not build alternate identifiers to track individuals as they browse across the web, nor will we use them in our products. This is a big step that will have massive consequences for the advertisement industry as a whole, but at the same time, companies do not just give up on revenue streams without having alternatives ready. My hunch would be that Google has become so big and collects data from so many other sources, that it simply doesn’t need your web browsing behaviour and third-party cookies to sell targeted ads effectively.
The Arizona House of Representatives just passed landmark app store legislation in a 31-29 vote on Wednesday that could have far-reaching consequences for Apple and Google and their respective mobile operating systems. The legislation, a sweeping amendment to Arizona’s existing HB2005, prevents app store operators from forcing a developer based in the state to use a preferred payment system, putting up a significant roadblock to Apple and Google’s ability to collect commissions on in-app purchases and app sales. It will now head to the state senate, where it must pass before its sent to Arizona Gov. Doug Ducey. A lot of bribes are going to flow from Apple and Google to Arizona, since if a law like this passes, it could have devastating consequences for these two companies. Obviously, I hope it passes, but I have my doubts local Arizona politicians will be able to withstand those juicy, juicy bribes.
There’s a spectrum of openness when it comes to computers. Most people hover somewhere between fully closed – proprietary hardware, proprietary operating system – and partly open – proprietary hardware, open source operating system. Even if you run Linux on your AMD or Intel machine, you’re running it on top of a veritable spider’s web of proprietary firmware for networking, graphics, the IME, WiFi, BlueTooth, USB, and more. Even if you opt for something like a System76 machine, which has open firmware as a BIOS replacement and to cover some functions like keyboard lighting, you’re still running lots of closed firmware blobs for all kinds of components. It’s virtually impossible to free yourself from this web. Virtually impossible, yes, but not entirely impossible. There are options out there to run a machine that is entirely open source, from firmware all the way up to the applications you run. Sure, I can almost hear you think, but it’s going to be some outdated, slow machine that requires tons of tinkering and deep knowledge, out of reach of normal users or people who just want to buy a computer, take it out of the box, and get going. What if I told you there is a line of modern workstations, with all the modern amenities we’ve come to expect, that is entirely open? The instruction set, the firmware for the various components, the boot environment, the operating system, and the applications? No firmware blobs, no closed code hiding in various corners, yet modern performance, modern features, and a full, modern operating system? Now you’re playing with POWER Most people’s knowledge and experiences with the Power ISA begins and ends with Apple. The company used Power-based processors from 1994 until 2006, when it switched to using processors from Intel and the x86 ISA. Aside from Apple, there are two other major cornerstones of the Power ISA that most people are familiar with. First, game consoles. The GameCube, Wii, Xbox 360 and PlayStation 3 all used PowerPC-based processors, and were all widely successful. Second, various embedded systems use Power processors as well. Aside from Apple, game consoles, and embedded systems, IBM has been developing and using processors based on the Power ISA for a long time now. IBM released the first Power processor in 1990, the POWER1, for its servers and supercomputers. They’ve steadily kept developing their line of processors for decades, and they are currently in the process of rolling out POWER10, which should be available later this year. Other Power ISA processors you may have heard of, such as the PowerPC G4 or G5 or the various gaming console processors, do not necessarily correspond to IBM’s own POWERx generations of processors, but are implementations of the same ISA. The nomenclature of the Power ISA has changed quite a bit over time, and companies like Apple and Sony using their own marketing names to advertise the processors they were using certainly didn’t help. To this day, PowerPC is often used as the name of the entire ISA, which is incorrect. The proper name for the ISA today is the Power ISA, but the confusion is understandable. The Power ISA, and related technologies, have been made freely available by IBM for anyone to use, and the specifications and reference implementations are open source, overseen by the OpenPOWER Foundation. The goal of the OpenPOWER Foundation is to enable the various partners involved in making Power hardware, like IBM, NXP, and others, to work together and promote the use and further development of the open Power ISA. In 2019, the OpenPOWER Foundation became part of the Linux Foundation. With Apple no longer making any Power-based computers, and with game consoles all having made the transition to x86, you may be left wondering how, exactly, you can get your hands on this fully open hardware. And, even if you could, how exotic and quirky is this hardware going to be? Is this another case of buying discard IBM POWER servers and turning them into very loud workstations with tape and glue, or something unrealistic and outdated no sane person would use? Thank god, no. Luckily for us, one company sells mainboards, POWER9 processors, and fully assembled POWER workstations: Raptor Computing Systems. Last year, they sent me their Blackbird Secure Desktop, and after many, many shipping problems caused by UPS losing packages and the effects of COVID-19, I can now finally tell you what it’s like to use this truly fully open source computer. Specifications The Blackbird Secure Desktop is built around Raptor’s Blackbird micro-ATX motherboard. This motherboard has a Sforza CPU socket, 2 DDR4 RAM slots compatible with EEC registered memory with a maximum combined capacity of 256GB, 2 PCIe 4.0 slots (16x and 8x), 2 gigabit Ethernet ports, another Ethernet port used for the BMC (OpenBMC – more on that later), 4 SATA ports (6Gb/s), and more than enough USB options (4 USB 3.0, 1 USB 2.0), and two RS-232 ports (one external, one internal using a header). On top of that, it has a CMedia 5.1 audio chip and associated jacks, an HDMI port driven by the on-board ASpeed graphics chip, as well as the ASpeed BMC. The board also comes with amenities we’ve come to expect from modern motherboards, like fan headers, an internal LED panel that displays the status of the motherboard, standard front panel connectors, a header for external audio, and so on. You also get a number of more exotic features, such as various headers to control the BMC, headers to update the open source firmware packages on the board, a FlexVer connector, and more. The only modern amenity that’s really missing from this board is an M.2 slot, which is something Raptor should really add to future revisions or new boards. In what will be a running theme in this review, for an exotic non-x86 ISA, the Blackbird motherboard is decidedly… Normal. Anyone who knows their way around a regular x86 motherboard won’t be confused by the Blackbird. Nor the
