GNOME Linux Desktop With Only Keyboard and a New Anniversary Release

  • How to navigate your GNOME Linux desktop with only a keyboard

    Almost ever since I first started using Linux, I've been on a mission to find the perfect window manager.

    My first experience with Linux was in the late 90s, and I first tried installing it on my own in the early 2000s. Like many converts, my previous experience was largely with Windows, and so my early mission was to find an experience that closely replicated Windows, or at least let me interact with it in a familiar way.

    [...]

    So I've been making a concerted effort to learn the GNOME keyboard shortcuts, and honestly, it hasn't been as hard to stick with them as I had thought. Just like any other set of keyboard shortcuts, the trick is to practice them a bit, and then do what you can to discourage you from slipping back into your old ways. I set my mouse just a wee bit further away, and when practical, will flip the switch on the bottom when I'm in a keyboard-heavy activity so I'm not tempted by muscle memory.

    The other trick is to have a good cheat sheet handy, posted up somewhere that you can easily see it. I made my own for GNOME, and I've created a version of it that you can download too.

    The GNOME project turns twenty-one years old this month, but as it keeps growing and evolving to keep up with the changing needs of computing environments, it wouldn't surprise me if I'm still using it twenty-one years from now. And if you are too, I hope you will have taken the time to learn the keyboard shortcuts by then.

  • GNOME Celebrates Its 21st Birthday By Releasing GNOME 3.29.91

    Today marks 21 years since the GNOME desktop environment project was started by Miguel de Icaza and Federico Mena. Coincidentally, released today is GNOME 3.29.91 that is the GNOME 3.30 desktop's second beta release.

  • Embedded Linux Conference Europe tackles tech’s diversity problem

    The Linux Foundation has posted session descriptions for the Embedded Linux Conference Europe and OpenIoT Summit Europe, to be held Oct. 22-24, in Edinburgh, with topics ranging from RISC-V to deep learning to workplace diversity.

    Even if you can’t make it to Edinburgh Oct. 22-24 for the Embedded Linux Conference Europe (ELCE) and co-located OpenIoT Summit Europe, the session descriptions are a good place to find clues about what’s hot in Linux and open source embedded technology. To be sure, the Linux Foundation offers a heavy dose of sessions on Linux Foundation projects such as Zephyr or Yocto Project, but it’s still a very inclusive collection from across the industry.

Rodrigo Siqueira's Work on VKMS

  • GSoC Final Report

    Nothing lasts forever, and this also applies for GSoC projects. In this report, I tried to summarize my experience in the DRI community and my contributions.

  • VKMS Coming In Linux 4.19 Is One Of The Best GSoC & Outreachy Projects Of The Year

    One of the student summer coding projects that ended up being a cross between Google Summer of Code (GSoC) and Outreachy was the VKMS driver to provide a virtual KMS implementation for headless systems and other interesting use-cases.

    Rodrigo Siqueira applied to GSoC 2018 to work on the long talked about "VKMS" driver while separately Haneen Mohammed had applied to Outreachy with a similar goal. Given the overlap, they worked together to get the Virtual KMS driver working. These summer student coding projects are drawing to a close and this initial driver is being sent sent into Linux 4.19 via the DRM tree. Not bad considering most GSoC/Outreachy projects introducing new code don't make it mainline so quickly, if ever.

Kernel: Speck/NSA, Big Networking Update, 64-bit ARM, Locking Down the Kernel

Filed under
Linux
  • Crypto Updates Sent In For Linux 4.19 Kernel, Speck Is Still In The Kernel

    The Linux kernel's crypto subsystem updates were sent out today with its new feature work for the Linux 4.19 kernel. One change we were curious to see was whether they were going to nuke the Speck cipher code, but they did not.

    Back during Linux 4.17, the Crypto updates added the Speck block cipher (and in 4.18, file-system encryption support with Speck was added) which has come under fire since Speck was developed by the US National Security Agency (NSA) and it's speculated that it could be back-doored by the agency but at the very least can't be a fully trusted for encryption.

  • The Big Networking Update Sent In For Linux 4.19, Including 802.11ax Bits

    David Miller sent in the networking subsystem updates today for the Linux 4.19 kernel merge window.

  • New round of 64-bit ARM Patches Merged into Linux 4.19 Kernel, Includes GCC Stackleak Plugin Support

    A new round of changes for 64-bit ARM architecture (ARM64/AArch64) were just loaded into the Linux 4.19 kernel merge window, and its generally some pretty good stuff being included.

    The 64-bit ARM space on Linux as been fairly busy, and there’s likely more to come before Linux 4.19 kernel is released.

  • 64-bit ARM Changes For Linux 4.19 Has "A Bunch Of Good Stuff"

    Will Deacon submitted the 64-bit ARM (ARM64/AArch64) changes on Tuesday for the Linux 4.19 kernel merge window.

  • Why Locking Down the Kernel Won’t Stall Linux Improvements

    The Linux Kernel Hardening Project is making significant strides in reducing vulnerabilities and increasing the effort required to exploit vulnerabilities that remain. Much of what has been implemented is obviously valuable, but sometimes the benefit is more subtle. In some cases, changes with clear merit face opposition because of performance issues. In other instances, the amount of code change required can be prohibitive. Sometimes the cost of additional security development overwhelms the value expected from it.

    The Linux Kernel Hardening Project is not about adding new access controls or scouring the system for backdoors. It’s about making the kernel harder to abuse and less likely for any abuse to result in actual harm. The former is important because the kernel is the ultimate protector of system resources. The latter is important because with 5,000 developers working on 25 million lines of code, there are going to be mistakes in both how code is written and in judgment about how vulnerable a mechanism might be. Also, the raw amount of ingenuity being applied to the process of getting the kernel to do things it oughtn’t continues to grow in lockstep with the financial possibilities of doing so.

    The Linux kernel is written almost exclusively in the C programming language — while the most significant reasons that the kernel needs to be hardened arise from aspects of this programming language.

  • NVIDIA are working towards better support for NVIDIA Optimus on Linux

    Thanks to a little Twitter tip, we've learned today that NVIDIA are indeed working to provide better support for NVIDIA Optimus on Linux.

    Currently, if you have a laptop with NVIDIA Optimus the official NVIDIA driver gives you the option between using the Intel GPU or switching over to the NVIDIA GPU. It doesn't handle it like you would expect it to on Windows, where it would offload the work to the more powerful NVIDIA GPU. Not an ideal situation, to switch between the two GPUs and from when I had a laptop with one (some time ago) it required logging out before it would take effect.

  • ACPI and Power Management Updates Merged into Linux 4.19

    ACPI and power management updates are never ending work, and today Intel’s Rafael Wysocki has submitted some note worthy updates for the Linux 4.19 kernel, which were merged thereafter by Linus Torvalds.

    For starters, this adds a new framework for CPU idle time injection, which will be used by all of the idle injection code in the kernel in the future. It also fixes a few issues and adds a number of fairly small extensions in a few places.

  • Musical Space: Open Source Music

    The term “open source” was coined 20 years ago this month by some software engineers who had the radical idea of allowing their code to be freely shared, copied and modified by anyone else. They realized they could make more money by giving away their product instead of selling it, and selling the support services instead. The open source model is a growing part of the arts, and nowhere more than in music. Recordings make so little money that creators now offer them for free and make their money from live shows instead.

  • BARR-C Aims to Make Us Better Programmers

    Look up “panacea” and you’ll find a bunch of C programming tools. Everyone and his dog has ideas about how to create better, more reliable C code. Use an ISO-certified compiler. Follow MISRA C guidelines. Write the comments first. Agile Programming. Energy crystals. The late-night remedies never end.

    Or, you could learn from the master. Michael Barr does embedded programming. He’s got a Masters in electrical engineering; was an adjunct professor of EE/CS; was Editor-in-Chief of Embedded Systems Programming magazine; founded consulting company Netrino to teach people how to write better code; then founded Barr Group to do it again. The man knows a few things about writing embedded software, mostly by watching his clients and students doing it badly. There’s no substitute for experience, and this guy has collected decades worth of it.  

    So it’s no surprise that he’s come up with his own little black book of programming pointers. These are the rules, guidelines, and suggestions gleaned from years of reviewing other peoples’ bad code and then fixing it. Best of all, a PDF download of the book is free. If you’re a traditionalist, you can buy the paperback version from Amazon.

It looks like Valve is working behind the scenes on enabling Linux game compatibility tools to work on Steam.

These compatibility tools allow games developed for Windows to work on Linux, similar to how the popular tool Wine has been doing for years on Linux and other Unix-based operating systems.

Earlier this week, strings of code were discovered by SteamDB in Steam’s database.

The code appears to be referencing an as yet to be revealed compatibility mode, complete with several UI elements, a settings menu, and what looks like the ability to force it on.

  • Akademy 2018 – Vienna

    The last Akademy I attended was in 2015, in A Coruña, Galicia, Spain. I skived off Berlin 2016, when I was burned out working as a consultant at Quby, and again Almería 2017, when I was struggling with the Krita Foundation’s tax problems. But this year, we could afford to go, and Akademy is in Vienna this year… And I’ve always wanted to see some works in Vienna’s Kunsthistorisches Museum — Cellini’s Salt Cellar, Rogier van der Weyden’s Crucifixion, Cranach’s Saxon Princesses... Things I’d only ever seen in books.

Benchmarks on GNU/Linux

  • Linux vs. Windows Benchmark: Threadripper 2990WX vs. Core i9-7980XE Tested
    The last chess benchmark we’re going to look at is Crafty and again we’re measuring performance in nodes per second. Interestingly, the Core i9-7980XE wins out here and saw the biggest performance uplift when moving to Linux, a 5% performance increase was seen opposed to just 3% for the 2990WX and this made the Intel CPU 12% faster overall.
  • Which is faster, rsync or rdiff-backup?
    As our data grows (and some filesystems balloon to over 800GBs, with many small files) we have started seeing our night time backups continue through the morning, causing serious disk i/o problems as our users wake up and regular usage rises. For years we have implemented a conservative backup policy - each server runs the backup twice: once via rdiff-backup to the onsite server with 10 days of increments kept. A second is an rsync to our offsite backup servers for disaster recovery. Simple, I thought. I will change the rdiff-backup to the onsite server to use the ultra fast and simple rsync. Then, I'll use borgbackup to create an incremental backup from the onsite backup server to our off site backup servers. Piece of cake. And with each server only running one backup instead of two, they should complete in record time. Except, some how the rsync backup to the onsite backup server was taking almost as long as the original rdiff-backup to the onsite server and rsync backup to the offsite server combined. What? I thought nothing was faster than the awesome simplicity of rsync, especially compared to the ancient python-based rdiff-backup, which hasn't had an upstream release since 2009.

  • The Unitary Fund: a no-strings attached grant program for Open Source quantum computing
    Quantum computing has the potential to be a revolutionary technology. From the first applications in cryptography and database search to more modern quantum applications across simulation, optimization, and machine learning. This promise has led industrial, government, and academic efforts in quantum computing to grow globally. Posted jobs in the field have grown 6 fold in the last two years. Quantum computing hardware and platforms, designed by startups and tech giants alike, continue to improve. Now there are new opportunities to discover how to best program and use these new machines. As I wrote last year: the first quantum computers will need smart software. Quantum computing also remains a place where small teams and open research projects can make a big difference. The open nature is important as Open Source software has the lowest barriers  for others to understand, share and build upon existing projects. In a new field that needs to grow, this rapid sharing and development is especially important. I’ve experienced this myself through leading the Open Source Forest project at Rigetti Computing and also by watching the growing ecosystem of open projects like QISKit, OpenFermion, ProjectQ, Strawberry Fields, XaCC, Cirq, and many others. The hackathons and community efforts from around the world are inspiring.
