  • Community Story: Building a Librem 5 app with Rust and GTK

    Could you introduce yourself and share how you got involved with GNOME development?

    I’m Bilal Elmoussaoui, I co-maintain GNOME Clocks and Sound Recorder and develop GNOME applications. I’m a long-time Linux user. I originally studied civil engineering and I’ve been learning to code for some time now, mostly writing web applications. I started contributing to GNOME projects while honing my Python skills.

    You are now a maintainer of several GNOME apps.

    Yes, I’ve started contributing to applications I use daily like FeedReader and Lollypop. The more I contribute, the more I learn about software development and the ecosystem. After a few years I found myself contributing to several GNOME applications, wherever I could make the user experience better for free software.

    Could you tell us about your recently released Read It Later app?

    Read It Later is a Wallabag client, which is a link saving service that you can host yourself. It includes all the basic features you would expect like managing and viewing articles. It also comes with easy-reader and dark modes in a beautiful and convergent design which adapts perfectly to desktop and mobile screens.

    What technology did you use to create Read It Later?

    I used to write applications with Python/Vala and GTK until late this summer when I got “The Rust programming language” book. It just sat on my desk for a while but I finally decided to pick something small to work on and made a simple Rust and GTK application template. The moment I opened my first GTK window with Rust I was hooked. The Rust GTK bindings have evolved a lot and we now have libhandy Rust bindings for adaptive widgets. Now I always pick Rust as a programming language, Meson as a build system and Flatpak to distribute my applications.

    How did you discover libhandy and are you a mobile Linux enthusiast?

  • Georges Basile Stavracas Neto: Welcome 2020

    I’m continuously failing to keep up with the Friends of GNOME donors. I really have to empty this queue as soon as possible.

    I’m really unhappy with the political situation of my country, Brazil. A halfwitted, fascism flirting populist was democratically elected. The public institutions were dominated by their inapt followers. Rich are getting richier, poor are getting poorer, inequality is skyrocketing, and despite all of that, a massive number of citizens seems to be applauding this madness, regardless if they’re profiting or not with this situation. I’m not comfortable with the idea of living here. I’m also not comfortable with the idea of leaving family behind. It seems this trend is spreading all around the world, so where else could I go anyway?

    I’ve also stopped training martial arts. I got involved with Aikido when I was 14. I was a vulnerable, not intellectually emancipated teenager that needed emotional crutches to carry on. For years, Aikido was part of my identity, and I would ignore blatant problems that surrounded it for the sake of keeping the narrative. Feeling like a virtuous warrior was good, after all. Over time, and with the maturity that came with it, the toxicity of it took a toll on me. Quitting it was traumatic. I still feel a big void.

    Quitting martial arts meant I stopped exercising. Turns out, the lack of physical activities, together with an awful political climate, and the stress of being an open source maintainer, is an express highway to depression. When I wrote “On Being a Free Software Maintainer“, I was already going downhill. Things got progressively worse until around GUADEC. Fortunately, the support from the GNOME community, my wife, family, and friends, were strong enough to allow me break this downward spiral.

    I do not know what would have happened without this support. To my family, wife, friends, and the GNOME community: thank you all so much for being here when I most needed.

    In the next two posts we will examine the etiquette of using Phabricator. This post will examine tips from the reviewer’s perspective, and next week will focus on the author’s point of view. While the social aspects of etiquette are incredibly important, we should all be polite and considerate, these posts will focus more on the mechanics of using Phabricator. In other words, how to make the review process as smooth as possible without wasting anyone’s time.

  • Robert O'Callahan: Visualizing Control Flow In Pernosco

    In traditional debuggers, developers often single-step through the execution of a function to discover its control flow. One of Pernosco's main themes is avoiding single-stepping by visualizing state over time "all at once". Therefore, presenting control flow through a function "at a glance" is an important Pernosco feature and we've recently made significant improvements in this area. This is a surprisingly hard problem. Pernosco records control flow at the instruction level. Compiler-generated debuginfo maps instructions to source lines, but lacks other potentially useful information such as the static control flow graph. We think developers want to understand control flow in the context of their source code (so approaches taken by, e.g., reverse engineering tools are not optimal for Pernosco). However, mapping potentially complex control flow onto the simple top-to-bottom source code view is inherently lossy or confusing or both. For functions without loops there is a simple, obvious and good solution: highlight the lines executed, and let the user jump in time to that line's execution when clicked on. In the example below, we can see immediately where the function took an early exit.

  • Marco Castelluccio: On code coverage and regressions

    There are two schools of thought when it comes to code coverage: those who think it is a useless metric and those who think the opposite (OK, I’m a bit exaggerating, there are people in the middle…). I belong to the second “school”: I have always thought, intuitively, that patches without tests are more likely to cause postrelease regressions, and so having test coverage decreases risk. A few days ago, I set out to confirm this intuition, and I found this interesting study: Code Coverage and Postrelease Defects: A Large-Scale Study on Open Source Projects. The authors showed (on projects that are very different from Firefox, but still…) that there was no correlation between project coverage and the amount of bugs that are introduced in the project and, more importantly, there was no correlation between file coverage and the amount of bugs that are introduced in the file.

Nvidia GPU Passthrough To Windows VM From Linux Host

Nvidia has now officially enabled GPU passthrough support for Windows virtual machines on GeForce graphics cards. In other words, this effectively means it?s possible to run a Linux machine and then run a virtual Windows machine within it, and hand that unfettered access to a graphics card. This is a big win for those wanting to run Windows games from within a virtual machine on your Linux desktop. They will be able to play Windows-based games using a virtual machine with GPU passthrough enabled. Read more

  • A brief intro to Red Hat OpenShift for Node.js developers – IBM Developer

    Container-based deployment models are the modern way to develop and deliver your applications. The most common tool for building with containers is Kubernetes, an open-source container-orchestration system for automating computer application deployment, scaling, and management. Kubernetes has helped usher in a standardized way to deploy and manage applications at scale, but it can be a sprawling, difficult beast to manage when your application becomes more mature and more complex. A company will need to have a robust DevOps team to manage a full-fledged Kubernetes-based production system. [...] My colleague, JJ Asghar summed it up nicely: “OpenShift provides creature comforts to talk to the Kubernetes “API”—at the same level of robustness—as long as you’re willing to use the opinions OpenShift brings.” The good news? Those opinions are tried and tested, enterprise-ready choices with the backing and support of Red Hat. So, what do Node.js developers need to know about OpenShift deployment? This blog post covers the “what” and “how” of deploying your Node.js application in an OpenShift environment.

  • How Red Hat data scientists use and contribute to Open Data Hub

    Artificial intelligence (AI) and machine learning (ML) drive much of the world around us, from the apps on our phones to electric cars on the highway. Allowing such things to run as accurately as possible takes huge amounts of data to be collected and understood. At the helm of that critical information are data scientists. So, what’s a day on the job look like for data scientists at Red Hat? Don Chesworth, Principal Data Scientist, gives you a glimpse into his day-to-day in a short video (aptly named "A Day in the Life of a Red Hat Data Scientist") that’s now available on our website. Isabel Zimmerman, Data Science Intern, provides a look at some of the tools she uses on the job in "Using Open Data Hub as a Red Hat Data Scientist." We’ll cover some of the highlights in this post.
