Links 18/5/2021: Istio 1.10 and KernelShark 2.0

Posted in News Roundup at 5:52 pm by Dr. Roy Schestowitz

  • GNU/Linux

    • Desktop/Laptop

      • There are two kinds of desktops: Yours and someone else’s

        The exception is Linux. (I know there are other independent desktop operating systems; FreeBSD springs quickly to mind.)

        The reason Linux still matters on the desktop, and always will, is that it’s the only desktop where the end-user is in control.

        That’s the good news. That’s also, in a way, the bad news. There are many different ways to do things in Linux. That gives you a variety of choices, but it also means you — not Microsoft, Google or Apple — need to understand your choices and pick out the best one for you.

        Some of you are no doubt saying, “Yes! And that’s how it should be.” I’m with you. But, and this is why the Linux desktop is perpetually an also-ran in the desktop wars, most people just want to get their work done. They don’t know and they certainly don’t care about the differences between deb and rpm, the Debian and Red Hat fundamental package management formats.

        I and the Linux folks reading this know what I’m talking about when I say “package management.” But Joe and Jane User? They’ve already skipped that paragraph.

      • An Abridged Guide to the Enterprise Linux Landscape

        Whether you are welcoming CentOS Stream or looking for alternatives, the recent decision from the CentOS community to focus on CentOS Stream has forced a lot of technical leaders to rethink their Enterprise Linux strategy. Beneath that decision, the business landscape involving Linux has shifted and expanded since its enterprise debut in the late 90s, when IBM would invest $1 billion in its development.

        Today, Linux comes in every shape and size imaginable — with the kernel running on tiny low power computers and IoT devices, mobile phones, tablets, laptops all the way up to midrange and high-power mainframe servers.

        Cutting through that expansive selection to understand which Linux distributions truly align with the needs of a business can lead to more frictionless deployments and successful execution while minimizing waste in maintenance cycles and optimizing overall cost.

        This abridged guide to the Enterprise Linux landscape can give businesses an overview of which flavor (or flavors) of Linux will most adequately match their use cases.

        For those looking for a more comprehensive guide, be sure to check out the Decision Maker’s Guide to Enterprise Linux.

      • Intel Working On TTM Integration For Discrete vRAM Management – Phoronix

        More than a decade ago when the open-source graphics driver stack was being modernized with kernel mode-setting and better handling the stack for OpenGL, composited desktops and the like, TTM (Translation Table Maps) was born for managing GPU video RAM by the kernel Direct Rendering Manager drivers. While Intel initially expressed interest in TTM, they ultimately decided to create GEM as the Graphics Execution Manager for handling their video memory management needs. Now in 2021 with Intel aggressively pursuing discrete graphics, they are working on TTM support.

      • KernelShark 2.0 Released For Continuing To Visualize Linux Traces

        Two years after KernelShark 1.0 for visualizing the Linux kernel’s “trace-cmd” tracing, KernelShark 2.0 has now been realized.

        KernelShark continues to be tooled around visualizing the output from the trace-cmd command that interacts with the Linux kernel’s FTrace tracer. KernelShark 2.0 introduces the concept of data streams for loading and merging multiple trace files, a new design for its plug-in interface has been merged, and there are also modifications to its C API.

        • AMD Publishes Latest Linux Patch To Toggle Predictive Store Forwarding (PSF) – Phoronix

          It’s been a month and a half since AMD published a security analysis of their new Zen 3 “Predictive Store Forwarding” feature that while helping performance could theoretically lead to a new side-channel attack. While they published a Linux patch to allow disabling PSF if desired for increased security, to this day they remain in the works and have yet to be mainlined.

          Days after that security white-paper was published AMD began posting the Linux patches to disable PSF optionally for users concerned around the possible security implications of Predictive Store Forwarding. As of Monday, there have now been six rounds of these patches for simply offering up the PSF user control.

      • Top free Cockpit linux alternative web-based server manager tools

        The cockpit, a web-based Linux server manager comes out of the box in some RHEL and its based distros such as CetnOS, Rocky Linux, and AlmaLinux. Whereas other distribution users such as Debian, Ubuntu, etc can also install it. Using Cockpit, the system admin can conveniently administer and controlled servers remotely using a browser. It is an open-source tool and source code is available on the GitHub page. Furthermore, you can also switch to the command line at any time, for example, to start the webserver, create new user accounts; apart from it, the admins can also take a look at the systemd journal, check the load or start and stop services using a terminal with root access. Thanks to the responsive design of Cockpit, the user interface automatically adapts to different screen sizes, which in turn enables convenient access via smartphones. It can also be used to manage several Linux systems by simply installing Cockpit in other servers, and connecting them to the main server running with Cockpit.

        However, Cockpit is not the only open-source application that is available to server management platforms there are few good Cockpit alternatives available. And here we will learn what are those.

      • 1Password releases full-featured Linux desktop application | ZDNet

        I used to pride myself on being able to remember dozens of complex passwords. But, now I need to remember hundreds of passwords and I just can’t do it. That’s why password managers, such as 1Password, Keeper, and LastPass, are so important. All of which is fine and good… unless you’re running Linux. Now, Agilebits’ 1Password has finally given their customers what they’ve been asking for: A Linux version. After a long beta, the company has released its first Linux edition.

        [...]

        As Jeff Shiner, 1Password CEO said, “1Password for Linux is the latest step in our commitment to enterprise. While 1Password can be utilized by anyone, business or individual, we have seen a real need for robust Linux support – outside of just the browser – in DevOps and IT teams in larger organizations. 1Password for Linux means that the entire organization can be protected irrespective of their device choice.”

        At the same time, 1Password also supports open source. 1Password provides more than 250 open source projects with free 1Password accounts for their teams. 1Password developed the new platform with this community in mind, using a number of incredible open technologies such as Rust, Ring Crypto, and Electron, the cross-platform JavaScript application program. Many, but not all 1Password for Linux libraries have also been shared back with the community. These include an Electron hardener and secure defaults package that, together, create a secure frontend foundation for 1Password.

      • 1Password Desktop App for Linux Officially Released, Here’s How to Install It

        Because 1Password for Linux uses the same authentication mechanisms and APIs provided to all user applications, you can unlock 1Password with your Linux user account, fingerprint sensors, or any other authentication mechanism supported by PAM. The app uses the Linux kernel keyring to establish a fully encrypted connection between 1Password in your browser and 1Password for Linux. That means that if you unlock one, the other will also be unlocked when you switch to it.

        The app will work with most modern web browsers, such as Mozilla Firefox, Google Chrome, and other Chromium-based options.

          Last weekend was AlpineConf, the first one ever. We held it as a virtual event, and over 700 participants came and went during the weekend. Although there were many things we learned up to and during the conference that could be improved, I think that the first AlpineConf was a great success! If you’re interested in rewatching the event, both days have mostly full recordings on the Alpine website.

          What worked

          We held the conference on a BigBlueButton instance I set up and used the Alpine Gitlab for organizing. BigBlueButton scaled well, even when we had nearly 100 active participants, the server performed quite well. Similarly, using issue tracking in Gitlab helped us to keep the CFP process simple. I think in general, we will keep this setup for future events, as it worked quite well.

          This blog is my experience about how I started open-source contribution (with the motivation provided by GSoC). This includes the bugs and features I have worked on so far in addition to the way competitive programming and open-source affect me. The blog might have some new terms. So stay steady with me till the end and… let’s get started.

          Open-source projects usually have starter bugs tagged with “junior jobs”, “good first issue” etc. This is when I have pushed my first contribution to the world of open-source. It was about improving the quality of icons of KdeConnect in Hi-Dpi devices. Moreover, it was only 2 lines of code (yes! that’s how it started). Usually it takes some time for the developer to check the patch. Luckily, the developer was active at that moment and they merged my patch instantly.

It’s a good place to learn about all the new cool thing making it easier to build and distribute Linux applications. This motivated me to improve a bit more the presence of Plasma Mobile applications in Flathub, but also make various improvements to apps.kde.org.

          [...]

          To improve a bit the situation, for at least the package released by the release service, I started a merge request for the release-tools that adds more information to the AppStream file. This includes bugs fixed in the last version, a link to the tarball and the link to the announcement. A solution for other types of artifacts still need to be figured out, but since not all applications in the release service provide AppImages or Windows/macOS package, it’s more complicated.

          • Mozilla publishes position paper on EU Digital Services Act

            In December 2020 the European Commission published the draft EU Digital Services Act. The law seeks to establish a new paradigm for tech sector regulation, and we see it as a crucial opportunity to address many of the challenges holding back the internet from what it should be. As EU lawmakers start to consider amendments and improvements to the draft law, today we’re publishing our substantive perspectives and recommendations to guide those deliberations.

            We are encouraged that the draft DSA includes many of the policy recommendations that Mozilla and our allies had advocated for in recent years. For that we commend the European Commission. However, many elements of the DSA are novel and complex, and so there is a need for elaboration and clarification in the legislative mark-up phase. We believe that with targeted amendments the DSA has the potential to serve as the effective, balanced, and future-proof legal framework.

          • Introducing Site Isolation in Firefox

            When two major vulnerabilities known as Meltdown and Spectre were disclosed by security researchers in early 2018, Firefox promptly added security mitigations to keep you safe. Going forward, however, it was clear that with the evolving techniques of malicious actors on the web, we needed to redesign Firefox to mitigate future variations of such vulnerabilities and to keep you safe when browsing the web!

            We are excited to announce that Firefox’ new Site Isolation architecture is coming together. This fundamental redesign of Firefox’ Security architecture extends current security mechanisms by creating operating system process-level boundaries for all sites loaded in Firefox for Desktop. Isolating each site into a separate operating system process makes it even harder for malicious sites to read another site’s secret or private data.

          • Introducing Site Isolation in Firefox (Mozilla security blog)

            The Mozilla Security Blog announces that there is a new site-isolation mechanism available for testing in the Firefox browser. It’s a defense against Meltdown and Spectre exploits.

          • Hacks.Mozilla.Org: Introducing Firefox’s new Site Isolation Security Architecture

            Like any web browser, Firefox loads code from untrusted and potentially hostile websites and runs it on your computer. To protect you against new types of attacks from malicious sites and to meet the security principles of Mozilla, we set out to redesign Firefox on desktop.

            Site Isolation builds upon a new security architecture that extends current protection mechanisms by separating (web) content and loading each site in its own operating system process.

            This new security architecture allows Firefox to completely separate code originating from different sites and, in turn, defend against malicious sites trying to access sensitive information from other sites you are visiting.

            In more detail, whenever you open a website and enter a password, a credit card number, or any other sensitive information, you want to be sure that this information is kept secure and inaccessible to malicious actors.

          We’ve been writing about OpenMV open-source camera boards programmable with MicroPython at least since 2015, with the latest model OpenMV Cam H7 based on STM32H7 Cortex-M7 microcontroller introduced in 2018. But the company has now gone a step further with OpenMV PureThermal board equipped with a more powerful STM32H7 dual-core Arm Cortex-M7/M4microcontroller, and supporting FLIR Lepton 2 to 3.5 thermal imagers, allowing the system to overlay the thermal map on top of the image like an augmented reality app would do. It can do so on the integrated LCD display or on an HDMI display.

        • Spidermonkey Development Blog: Ergonomic Brand Checks will ship with Firefox 90

          When programming with Private Fields and methods, it can sometimes be desirable to check if an object has a given private field. While the semantics of private fields allow doing that check by using try…catch, the Ergonomic Brand checks proposal provides a simpler syntax, allowing one to simply write #field in o.

        • Jussi Pakkanen: Why all open source maintainers are jerks, the Drake equation hypothesis

          This blog post is meant to be humorous. It is not a serious piece of scientifically rigorous research. In particular it is not aiming to justify bad behaviour or toxicity in any way, shape or form. Neither does it claim that this mechanism is the only source of negativity. If you think it is doing any of these things, then you are probably taking the whole thing too seriously and are reading into it meanings and implications that are not there. If it helps, you can think of the whole thing as part of a stand-up comedy routine.

          [...]

          It seems common knowledge that maintainers of major open source projects are rude. You have your linuses, lennarts, ulrichs, robs and so on. Why is that? What is it about project maintenance that brings out these supposed toxics? Why can’t projects be manned by nice people? Surely that would be better.

        • Izhar Firdaus: Switching to use Ruby 2.7 (or older) in Fedora 34 using DNF Modules

          Fedora 34 now ships with Ruby 3.0 by default, which might be great news for Ruby developers. However, for those who might still be relying on older version of Ruby to run their stuff (eg: me), and don’t want to spend time updating things to make them work with Ruby 3.0 (like this Jekyll-based blog), the switch may be undesirable.

        • 4 essential characteristics of successful APIs

          If you are building an application that uses some variation of a client/server model, you need an application programming interface (API). An API is a clearly defined boundary between one process and another. A common boundary in web applications is a REST/JSON API.

          • Bardehle Pagenberg counsel sets up solo patent practice [Ed: JUVE doing an ‘ad’ for a longtime software patents propagandist]

            Bastian Best (41) is leaving Bardehle Pagenberg to work as a sole practitioner specialising in patent prosecution. Most recently, he was counsel at Bardehle Pagenberg. Above all, Best was also one of the firm’s main faces on social media such as Linkedin, YouTube and podcasts.

            [...]

            Despite the departure of Bastian Best in Munich, last summer Bardehle Pagenberg strengthened its Düsseldorf office by bringing on board Alexander Haertel. This hire added another experienced litigator, at an important court location, to the firm. Previously, Haertel was a founding partner of IP boutique Kather Augenstein, which in 2015 spun off from Preu Bohlig & Partner.

    The most abusive 'tech' company (akin to a cult disguised as "software company" since the 1970s) is distracting lawmakers and attacking Linux from the inside; thankfully, those insipid plans of theirs face major backlash from longtime kernel developers and GNU/Linux users

    The gross misuse or misapplication of the brand "Linux" is being highlighted in this video about the latest examples. It has gone too far; whether Linus Torvalds wishes to rock the boat that’s the so-called ‘Linux’ Foundation is totally up to him, but it might help if people contact him directly, especially longtime users and proponents of GNU/Linux.

    The laughing stock that the patent system, the patent law firms, and patent media became (over the past few years) must be replaced; at the moment we have a cabal connected to a bunch of criminals running the entire show and the public understandably grows impatient (at least people who are sufficiently informed; the criminals have already intimidated and bribed a lot of the media and they're still bribing more of it, as we shall demonstrate later today)



  30. [Meme] IRC Wars in a Nutshell

    In terms of large IRC networks, we’re in trouble (unless we self-host) because they seem to be dividing themselves along political lines rather than anything technical or something of an on-topic/relevant substance. Using networks for Free software projects/organisations to push one’s political agenda is not acceptable because it’s starting to seem like in IRC space, FN has become the Front Nationale (French) and LC is Liberal Coalition. Both FreeNode and Libera Chat have managed to turn from technical platforms into political parties, in effect using technical networks (intended for technical projects) to push someone's political agenda and thus misusing them for personal gain. There’s no free lunch. As it turns out, FreeNode’s new owner (Andrew Lee) has just outed himself as a huge Donald Trump supporter who speaks of “these fuckers who stole that shit” (he meant the election, which he insists Trump actually won in 2020).
