Why Linux stands out amongst other OSes

Filed under
OS
Linux

Up until recently, Elementary OS was my platform of choice. It's an elegant, simple, and user-friendly solution for the desktop. One thing that the Elementary developers do that I believe is fairly wise is to not allow upgrades from one major release to another. In other words, if you use Elementary OS Loki, you can't upgrade to Juno. To get the benefits of Juno, you must do a full-blown re-install of the OS.

Why is this route wise? My latest adventures in Linux will help explain.

A few months ago, I purchased a System76 Thelio. It's a beast of a desktop, while at the same a masterful work of art. Preinstalled on that desktop machine was System76's own Pop!_OS. Based on Ubuntu, it seemed like a great way for me to dive back into the GNOME desktop. So I did. It took no time to get accustomed to the new workflow with GNOME. Once my fingers understood the new keyboard shortcuts, I was good to go.

Rancher Labs Releases Slim OS for Its Edge-Focused K3s Platform

Filed under
OS
Ubuntu

Rancher Labs has developed an operating system for its recently launched edge-specific k3s Kubernetes distribution designed for resource-constrained environments and easier management when deployed within the k3s environment.

Sheng Liang, CEO and co-founder of Rancher Labs, said the conveniently named k3OS uses the same declarative syntax as other Kubernetes resources. This allows a user to install and upgrade the k3s platform and the k3OS at the same time.

Users can also use the k3OS platform to model infrastructure-as-a-code, which allows for repeatable cluster deployments and should make the k3s clusters more secure when running in isolated environments. It also has a reduced attack surface that further bolsters its security posture.

  • Intel Iris Gallium3D Picks Up Conservative Rasterization Support

    On top of Intel's new open-source OpenGL driver seeing some hefty performance optimizations, the Iris Gallium3D driver has picked up another OpenGL extension ahead of the Mesa 19.1 branching. 

    Iris Gallium3D now supports INTEL_conservative_rasterization alongside the existing support in the i965 driver. INTEL_conservative_rasterization is the several year old Intel extension for seeing if all fragments are at least partially covered by a polygon rather than the default rasterization mode of including fragments with at least one sample covered by a polygon.

  • Coreboot Finally Sees Zen/Ryzen Support In The Form Of Picasso APU Enablement

    The Coreboot open-source firmware/BIOS project has finally seen initial AMD Zen CPU support as part of Google engineers bringing up Picasso APU support in order to handle an upcoming Chromebook launch.

    The most recent AMD CPUs to be supported by Coreboot has been Stoney Ridge, the APUs with GCN graphics and two Excavator cores. That support was done by Google engineers on the Chromebook front with AMD themselves being out of the Coreboot game / open-source AGESA coverage for several years now. But coming in as bit of a surprise today was initial Zen APU / Picasso coverage.

  • Ian Bicking: “Users want control” is a shoulder shrug

    Making the claim “users want control” is the same as saying you don’t know what users want, you don’t know what is good, and you don’t know what their goals are.

    I first started thinking about this during the debate over what would become the ACA. The rhetoric was filled with this idea that people want choice in their medical care: people want control.

    No! People want good health care. If they don’t trust systems to provide them good health care, if they don’t trust their providers to understand their priorities, then choice is the fallback: it’s how you work the system when the system isn’t working for you. And it sucks! Here you are, in the middle of some health issue, with treatments and symptoms and the rest of your life duties, and now you have to become a researcher on top of it? But the politicians and the pundits could not stop talking about control.

  • 27 Excellent Free Books to Learn all about R

    The R language is the de facto standard among statisticians for the development of statistical software, and is widely used for statistical software development and data analysis. R is a modern dialect of S, one of several statistical programming languages designed at Bell Laboratories.

    R is much more than a programming language. It’s an interactive suite of software facilities for data manipulation, calculation, and graphical display. R offers a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible. The ability to download and install R packages is a key factor which makes R an excellent language to learn. What else makes R awesome? Here’s a taster.

  • Automate user acceptance testing with your DevOps pipeline

    Acceptance testing, also called user acceptance testing (UAT), determines whether a system satisfies user needs, business requirements, and authorized entity criteria. The tests are repeated every time there's a new design when the application is developed through software development lifecycle (SDLC). In many companies, the Site Reliability Engineer (SRE) automates acceptance testing by building a continuous integration/continuous development (CI/CD) pipeline within a DevOps initiative.

  • GStreamer buffer flow analyzer

    Gstreamer's logging system is an incredibly powerful ally when debugging but it can sometimes be a bit daunting to dig through the massive amount of generated logs. I often find myself writing small scripts processing gst logs when debugging. Their goal is generally to automatically extract some specific information or metrics from the generated logs. Such scripts are usually quickly written and quickly disposed once I'm done with my debugging but I've been wondering how I could make them easier to write and to re-use.

    gst-log-parser is an attempt to solve these two problems by providing a library parsing GStreamer logs and enabling users to easily build such tools. It's written in Rust and is shipped with a few tools that I wrote to track actual bugs in GStreamer elements and applications.

    One of those tool is a buffer flow analyzer which can be used to provide various information regarding the buffers exchanged through your pipeline. It relies on logs generated by the upstream stats tracer, so no modification in GStreamer core or in plugins is required.

  • GNU Wget Buffer Overflow Vulnerability [CVE-2019-5953]

    A vulnerability in GNU Wget could allow an unauthenticated, remote attacker to execute arbitrary code or cause a denial of service (DoS) condition on a targeted system.

    The vulnerability exists because the affected software performs improper bounds checks, which could result in a buffer overflow condition in the irc.c source code file. An attacker could exploit this vulnerability by persuading a user to retrieve a file that submits malicious input using the wgetcommand. A successful exploit could allow the attacker to execute arbitrary code or cause a denial of service (DoS) condition.The vendor has confirmed the vulnerability and released software updates.

  • The French Govt's Hand-Rolled Encrypted Messaging Service (Briefly) Allowed Anyone To Pretend They Were A Government Official

    Not only was Robert able to get his faux account validated within two hours of downloading the app, he was also able to obtain plenty of info linked to other government account profiles. On the bright side, the team behind the app reacted quickly to notification of the security flaw and suspended account creation until it could be patched. The French government has also instituted a bug bounty program for Tchap, which will hopefully result in further flaws being addressed before they're exploited by criminals or state-sponsored hackers.

    To be fair, Tchap is still in its "beta" stage. But that's not much comfort considering it was rolled out for use in this state, exposing government employees' personal account info and allowing any outsider to take a seat at the Tchap table just by exploiting the system's less-than-robust validation process.

  • Google Chrome 74 Released for Windows, macOS, and Linux; Dark Mode Arrives on Windows

    Google has released Chrome 74 for Windows, Mac, Linux, Chrome OS, and Android (beta). The latest release brings a number of new features apart from quite a few bug fixes. Probably the biggest highlight of Chrome 74 is support for dark mode on Windows. After arriving on the Mac last month, support for dark mode in Chrome is finally available on Windows. Google Chrome currently has over 1 billion users worldwide.

  • Data Saver is now Lite mode

    Since we introduced Data Saver in Chrome, we’ve reduced users’ data usage by up to 60 percent. But now, the feature is expanding to provide more benefits in addition to data savings. Pages will now load faster, in some cases considerably faster, and use less memory. This is why starting today, we will be renaming Data Saver to Lite mode.
    Lite mode will continue to reduce data use by using Google servers to compress the pages you visit before downloading them. Using the NetworkInformation API, Lite mode tells web servers that you are interested in receiving a version of the site that uses less data if one is available.
    Lite mode also helps improve page loads. If Chrome predicts that a page will take longer than 5 seconds for the first text or image to show on screen, it will load a Lite version of the page instead. Lite pages are highly optimized to load considerably faster. A whitepaper will be published in the coming months that will explain this in more detail.

  • Google Chrome 74 Released: Dark Mode For Windows, Lite Mode For Android

    Google released the Chrome version 74 today for Windows, Mac, Linux, Android, and Chrome OS users. The new version comes with new features and bug fixes with the main highlight being support for a Dark Mode in Windows.

    Other noteworthy changes include the replacement of Data Saver feature with Lite Mode for Chrome on Android devices. There are a few security improvements too, so read on to find out the details.

KDE’s Snap Packages

Filed under
KDE

The Linux world has always worked with a develop and deploy model where software gets written by projects such as KDE and then distro projects pick that up, polish it and give it to the user. No other computer environment works like this and it goes against the fashion of DevOps concepts where the people who code are empowered to deploy to the end user going through QA as appropriate. We changed that with KDE neon where we brought the packaging into KDE making .deb packages. That integration allows for blockages and imperfections which get identified to be solved easily through the most efficient channels. Kipi Plugins is a good example of this, KDE dropped the ball here by stopping releases. Nobody noticed until as a packager I wondered where it had gone, realised it was no longer being released and, because I work directly in the project responsible, could easily fix that in the right place. With new containerised formats Linux is changing, and projects like KDE can now package software and send it direct to the user. I’ll discuss this more in a future blog post but for now lets look at Snaps where last week, for the first time, KDE Applications was released with 50-odd apps available directly for all to enjoy direct from the Snap Store.

Filed under
Graphics/Benchmarks

Almost exactly four months ago I announced Cage, my Wayland compositor for a kiosk-like environment. To the uninitiated: a kiosk is designed for running a single, maximized application and preventing the user from interacting with any other part of the system. You’ve probably seen many in your life in malls, stores or even the dentist (how satisfied are you with your service?). Kiosks can also be used for much cooler things, though, such as running home automation systems.

    Next week, members of the open source community will descend upon Denver in hordes unseen since the gold rush that resulted in the city being formed back in the late 1800’s (probably). That’s right, it’s the very first Open Infrastructure Summit – bringing together some of the finest minds across the open source community to discuss, demo and deliberate all things OpenStack, Kubernetes, ONAP, Kata Containers, Airship, Zuul, and much, much more.
    We’re particularly excited about this summit as we’ll be unveiling SUSE OpenStack Cloud 9 to the world there, having pre-announced it earlier in the month at SUSECON in Nashville. As the first company to produce an enterprise-ready OpenStack distribution back in 2012, we continue to work to make OpenStack easier for companies to implement in an enterprise environment, giving a stable, production-ready base for business-critical systems and applications to run on.
