Linux
  • Facebook Has Been Working On BOLT'ing The Linux Kernel For Greater Performance - Phoronix

    For several years now Facebook engineers have been working on BOLT as a way to speed-up Linux/ELF binaries. This "Binary Optimization and Layout Tool" is able to re-arrange executables once profiled to generate even faster performance than what can be achieved by a compiler's LTO and PGO optimizations. One of the latest BOLT efforts has been on optimizing the Linux kernel image.

  • OpenZFS 2.0.6 Released With Support For Newer Kernels

    While the OpenZFS 2.1 feature release has been available since July, for those still using the OpenZFS 2.0.x series and not yet prepared to make the jump to that big new release with dRAID and other changes, OpenZFS 2.0.6 was released this week.

    OpenZFS 2.0.6 is another maintenance release for those not migrating yet to the v2.1 series. OpenZFS 2.0.6 most notably brings support for newer versions of the Linux kernel: OpenZFS 2.0.5 supported up through Linux 5.12 while OpenZFS 2.0.6 now supports Linux 5.13/5.14 plus some early 5.15 compatibility patches.

  • Intel's User Interrupts With Sapphire Rapids Looking Quite Great For Faster IPC - Phoronix

    Earlier this month Intel engineers posted their initial Linux kernel enablement around x86 User Interrupts with this feature premiering with Xeon "Sapphire Rapids" CPUs.

Intel talked more about User Interrupts this week at LPC2021.

Firefox and Hardware Acceleration on Linux

Filed under
GNU
Linux
Moz/FF

In some Firefox version after 88.0 it looks like they're enabling WebRenderer by default, and it also looks like my hardware (an Nvidia graphics card with the proprietary driver)[1] isn't whitelisted, so what Firefox does is enable "software WebRenderer" instead.

First things first, I had been trying WebRenderer for some time (more than a couple of month) by force-enabling it, and while it seemed to make things better at first, on the whole the experience was awful, and because WebRenderer, if I understand correctly, uses GPU acceleration, that affected the rest of the desktop, so after a while I disabled WebRenderer (and "Hardware Acceleration" in the preferences tab, and set the processes limit to 2, while I was there), and then things seemed to be better.

Due to the iffy state Firefox can be in sometimes, I had decided to skip updates for as long as I can, i.e. I update Firefox, then stick with the version I have until an extension I use no longer works, or there is a really compelling new feature in a new version of Firefox (which, sadly, doesn't seem to be as often as it was before the "rapid release" schedule Mozilla had adapted...). So here I was using Firefox 88.0, shut the machine down at night, turned it on in the morning, then when I was opening a link, Firefox started and all the tabs had the "your tab crashed" "reload this tab?" message, clicking that button had no effect.

So nothing worked, not restoring the previous tabs, disabling all extensions, moving ~/.mozilla and starting anew; a couple of online searches later, still nothing, then I looked at rpm -qa --last | less, now I think the reason is a glibc update, which broke Firefox, probably it would be fixed by rebuilding Firefox against the new glibc. Not really OpenSuse Tumbleweed's problem because the current version of Firefox in the repos is 92.0...

What Is GNU/Linux?

Filed under
OS
GNU
Linux

Before diving headfirst into the wonky world of GNU/Linux systems, it's important to understand how they came about and some of the terms you may encounter while researching and using them. I'll start with a brief history of the big three: UNIX, Linux, and GNU.

UNIX is a proprietary, command-line-based operating system originally developed by Dennis Ritchie and Ken Thompson (among others) at AT&T's Bell Labs in the late 1960s and early 1970s. UNIX is coded almost entirely in the C programming language (also invented by Ritchie) and was originally intended to be used as a portable and convenient OS for programmers and researchers. As a result of a long and complicated legal history involving AT&T, Bell Labs, and the federal government, UNIX and UNIX-like operating systems grew in popularity, as did Thompson's influential philosophy of a modular, minimalist approach to software design.

During this period, Richard Stallman launched the GNU Project with the goal of creating "an operating system that is free software." GNU, confusingly, stands for "GNU's Not UNIX." This project is responsible for the UNIX-like GNU OS. Stallman also launched the related Free Software Foundation (FSF) on the principle that "any user can study the source code, modify it, and share the program" for any participating software.

Steam Deck/Arch Linux Latest

Filed under
Gaming
  • Steam Deck can be used as a PC controller and run multiple systems

    We already knew that the Steam Deck was going to be more than just a typical handheld game console. In a new section of frequently asked questions, Valve has answered some of the doubts that its potential buyers may have, and, at the same time, has confirmed some of its added capabilities.

    Perhaps the most interesting thing is that it can be used as a controller for games on PCs. All that needs to be done is to connect the Steam Deck to a personal computer via Remote Play and configure it as a controller. Sounds really good.

  • Valve confirms Steam Deck can be used as PC controller, does not support external GPUs

    We already know that the Steam Deck will have more features than your typical handheld gaming console, and Valve has just revealed another of its functions: the ability to be used as a PC controller. But one thing it won’t have is support for external GPUs, which was pretty much expected, admittedly.

    In a new FAQ, Valve answers what it says are the 20 most popular questions about Steam Deck. Probably the most interesting revelation is confirmation that the handheld can be used as a controller for your PC games. All you have to do is connect the Steam Deck to your computer via Remote Play.

  • Valve Posts Official Steam Deck FAQ: Supports MicroSD Booting, Remote Play for PC

    Valve's upcoming Steam Deck gaming console is set to start shipping in December of this year, and interest is high for the handheld gaming console. Steam Deck buyers have a lot of upfront questions, though, so Valve has posted a frequently asked questions (FAQs) page to share some more details about the new system.

    As a reminder, the Steam Deck gaming console is Valve's attempt to enter the handheld gaming market, and it wields a custom AMD APU. Featuring four cores and eight threads of Zen 2 core IP, the chip runs at 2.4–3.5 GHz clock speeds. It also features an RDNA 2 graphics engine with eight compute units running at 1.0–1.6 GHz. The APU is rated for a thermal power budget of anywhere from 4W to 15W, and it connects to 16GB of LPDDR5 RAM running at 5500 MT/s. For external storage, there's a high-speed microSD card slot. This is all tied together by a custom Arch Linux-based operating system with Valve's Steam UI on top of it.

  • AMD's new Linux CPU driver for the Steam deck is showing promising results

    No one really knows when you'll be able to get your hands on a Steam Deck, with shipping dates slipping into the second quarter of 2022. In the meantime, Valve and AMD are working to squeeze more performance out of the Zen 2 SoC inside the new handheld console, as well as improve its energy efficiency.

    Valve's upcoming Steam Deck will be able to run Windows 11 for those who want it, but the majority of users will likely stick with the company's own Arch Linux-based SteamOS 3.0, which uses the Proton compatibility layer to run games that don't run natively on Linux.

Growth of the Fedora Distribution over time

Filed under
Red Hat

There was a conversation in IRC (libera.chat, #fedora-admin) on the amount of disk space that Fedora is using over time. It used to grow astronomically over time, but there was an idea that it might be slowing down.. and then the realization that no one had graphed it. Taking this challenge in hand I decided to look at it. Doing a complete mirror of the data would require me to have a very long time frame and 100+ TB of disk space, but luckily for me, the Fedora mirror system does a du every night and outputs this data to a file, https://dl.fedoraproject.org/pub/DIRECTORY_SIZES.txt

The file covers all the directories that the main download servers have including the archive trees which are where old releases go to live. It also puts it in a ‘human-readable’ format like...

This week in KDE: Plasma on the move

Filed under
KDE

Plasma 5.23’s beta period is half over, and we’re busy fixing issues found by our wonderful users. One thing to note is that I don’t mention fixes for regressions that never shipped to users in final releases, and this includes beta versions. If I included those, the list below would be much longer! Because rest assured, we have been fixing tons and tons of the bugs and regressions that all your faithful QA has caught during the beta period. All those bug reports are really valuable. So please do keep filing them! Bug reporting isn’t a black hole!

In the Plasma Wayland session, KWin now supports “DRM leasing”, which allows us to re-add support for VR headsets and let them achieve optimal performance (Xaver Hugl, Plasma 5.24)

Cross Compile to PinePhone Part Three

Filed under
Linux
Gadgets

On last part, we managed to generate package by hand. While it works, having a script to do everything for us is even better. So I’ve wrote a small python script to automate the process.

Apart from the SDK issue mentioned above, we still need to write proper tutorials on https://develop.kde.org/ about cross compile. I’m happy with the overall result, to be able to cross compile to target platform is essention to mobile development. The major difference between Plasma Mobile and Android/iOS is apps on Plasma Mobile are neither self-contained or static linked. Together with the updating of system libraries it’s impossible to ship a static SDK, you’ll need to have all the dynamic linked libraries on rootfs. For iOS and Android, the only dynamic linked libraries is system ones, and they don’t change throughout one major version. You can have Android 10 SDK for Android 10, 11 SDK for 11… But for Plasma Mobile Manjaro, it’s a rolling distribution, you’ll also need a rolling SDK.

I hope the ablity to cross compiling to PinePhone can improve everyone’s productivity on Plasma Mobile development, however it’s just a small step towards what Android and iOS have. We still lack phone emulator, remote debugging and UI debugging tools.

  • The brains behind the books - part IX: Meike Chabowski | SUSE Communities

    Linux and I share the same birthday – it probably was just kismet that we met. No wonder that I seized my chance when I saw a job opening from SUSE in the newspaper – they were looking to hire somebody into the Marketing /PR department for press relations. I applied for the job, and got it – strike! This was in 2000 – more than 21 years ago. The first 6 weeks I worked as PR manager, and published my first press release about SUSE Blinux, a Braille screen reader developed by our former colleague Marco Skambraks. In the meantime, we had got a new Marketing director. And one fine day, he asked me if I would move over from PR to Product Marketing. Quite overrun, I said “why not, let’s try it”. And for the next 16 years, I worked as a product marketing manager on many different and interesting topics. I am very proud that, in 2000, I was among those that brought the very first Enterprise Linux server to market – it all started in 2000 with SUSE Linux Enterprise Server for S/390 (IBM mainframes). The mainframe (today IBM Z and LinuxOne) was my first love, but I also was responsible for High Performance Computing for a very long time, and I am still addicted to this technology area, as HPC is so much impacting our daily life without us realizing it. Other topics I worked on were UNIX to Linux, SUSE Linux Enterprise Server in general, SUSE Linux Enterprise Point of Service, and also SUSE Manager. Already during my time in Product Marketing, I wrote technical feature guides, and together with subject matter experts, technical whitepapers focussing on many different topics (A NUMA API for Linux from Andi Kleen, for example, is still out there, and regularly referred to).

    There was a time when people like us might own a tube tester and even if you didn’t, you probably knew which drug store had a tube testing machine you could use for free. We aren’t sure that’s a testament to capitalistic ingenuity or an inditement of tube reliability — maybe both. As [Usagi] has been working on some tube-based projects, he decided he needed a tester so he built one. You can see the results in the video, below.

    The tester only uses 24V, but for the projects he’s building, that’s close to the operation in the real circuits. He does have a traditional tube tester, but it uses 100s of volts which is a different operating regime.

  • Cybersecurity Threat Vectors For AI Autonomous Cars

    It might seem puzzling that there is any connection between those pesky possums and the topic of cybersecurity and self-driving cars. As will soon be apparent, the parade of possums that you could suggest “attacked” my house is somewhat analogous to those dastardly human hackers that try to break into computer systems. And when you give this matter some careful thought, it is apparent that a self-driving car is really a computer on wheels.

    Self-driving cars are chock-full of computers.

    Computers underpin the AI driving system. These are typically specialized processors especially souped-up to perform lots of computations, something sorely needed to autonomously drive a car. By and large, the computer processing onboard a self-driving car is awe-inspiring and rivals the kind of supercomputers that we used to call supercomputers back in the olden days (to clarify, today’s supercomputers are still many times faster than the computers put into a self-driving car, so my comparison is to the prior eras of supercomputers).

    But the computers for self-driving purposes are just one instance of computing that is found inside a modern car.

  • The real stakes of Apple’s battle over remote work

    And those are just the potential consequences in the short term. This fight will have bigger ramifications later on. That this battle is happening at Apple signals a major shift for the company. For the most part, until now, it’s managed to avoid the internal conflicts that have seized other tech companies like Google. Now Apple will need to reckon with internal employee activists who are learning to pressure their employer about issues beyond remote work, like pay parity and gender discrimination. Even when the question of remote work is eventually settled, its employees are now emboldened to push for other demands — and so Apple will likely continue to grapple with this challenge.

6 open source tools for orchestral composers

Filed under
OSS

As an avid amateur musician, I've worked with many different software programs to create both simple and complex pieces. As my projects have grown in scope, I've used composition software ranging from basic engraving to MIDI-compatible notation to playback of multi-instrument works. Composers have their choice of proprietary software, but I wanted to prove that, regardless of the need, there is an open source tool that will more than satisfy them.

When my needs were simple and my projects few, I used the excellent resource Lilypond, part of the GNU project, for engraving my music score. Lilypond is a markup language used to create sheet music. What looks like a mass of letters and numbers on the screen becomes a beautiful music score that can be exported as a PDF to share with all your musical acquaintances. For creating small snippets of a score, Lilypond performs excellently.

  • New Book: Krita Secrets by Bohdan Kornienko

    “Krita Secrets” is a book that aims to deliver as short tutorials as possible. Each tutorial covers one specific action with its result. The tutorials range from how to do little tricks, like draw Parallel Lines, to complex tools such as Gradient Mesh. By September 22, 2021 the book contains 60 tutorials and it keeps growing.

    The intent is to create a compendium of short tutorials that each aim to solve one single problem. This way people will not have to spend a lot of time reading through pages online, or watching video after video, while figuring things out. Hopefully with the help of this book artists would spend more time creating than searching online for instructions.

  • How To Zoom Tmux Panes For Better Text Visibility In Linux - OSTechNix

    I have been using GNU Screen and Tmux terminal multiplexers for many years now. They comes in handy when performing different tasks in multiple terminal windows simultaneously. Today I learned one of the useful feature of Tmux - Zooming panes. Yes, we can zoom Tmux panes to fit them into the full size of current Terminal window for better text visibility and for viewing more of its contents.

    It is useful when you need more space or focus on a specific task. After finishing that task, you can zoom out (unzoom) the Tmux pane back to its normal position or size.

  • Make Linux look like Windows 10

    As the days pass, Linux is on its way to becoming the go-to operating system for users.

Security and DRM Leftovers

Linux 5.15-rc3

So after a somewhat rocky merge window and second rc, things are now
actually looking pretty normal for rc3. Knock wood.

There are fixes all over, and the statistics look fairly regular, with
drivers dominating as they should (since they are most of the tree).
And outside of drivers, we have a fairly usual mix of changes -
architecture fixes, networking, filesystems, and tooling (the latter
being mostly kvm selftests).

Shortlog appended, it's not too long and easy to scan through to get a
flavor for the details if you happen to care.

Please do give it a whirl,

             Linus

Huawei launches OS openEuler, aims to construct 'ecological base of national digital infrastructure'

Chinese tech giant Huawei launched openEuler operating system (OS) on Saturday, another self-developed OS after the HarmonyOS, as it tries to "solve the domestic stranglehold problem of lacking its homegrown OS in basic technology," and build a full-scenario covered ecosystem to prepare for more US bans. The openEuler OS can be widely deployed in various forms of equipment such as servers, cloud computing and edge computing. Its application scenarios cover Information Technology, Communication Technology and Operational Technology to achieve unifying an operating system with multi-device support, according to the company's introduction. In the ICT field, Huawei provides products and solutions such as servers, storage, cloud services, edge computing, base stations, routers, industrial control among others, all of which need to be equipped with an OS. Huawei has therefore been building capabilities to achieve a unified OS architecture, and meet the demands of different application scenarios, the firm said on Saturday. The openEuler program was initially announced back in 2019 as an open source operating system. Today's launch is an updated one. Read more
