Qt/KDE: Qt5 in Debian and Slackware, QtCreator on Android, KDE Discover, and Plasma's 10th Anniversary

Filed under
KDE
  • moving Qt 4 from Debian testing (aka Buster): some statistics, update II

    We started filing bugs around September 9. That means roughly 32 weeks which gives us around 5.65 packages fixed per week, aka 0.85 packages per day. Obviously not as good as we started (remaining bugs tend to be more complicated), but still quite good.

  • [Slackware] Plasma5 – April 18 edition for Slackware

    The KDE-5_18.04 release of ‘ktown‘ for Slackware-current offers the latest KDE Frameworks (5.45.0), Plasma (5.12.4) and Applications (18.04.0). The Qt5 was upgraded to 5.9.5. Read the README file for more details and for installation/upgrade instructions. Enjoy the latest Plasma 5 desktop environment.

  • Perfect Debugging Experience with QtCreator on Android

    While I was working on a yet-to-be-announced super secret and cool Qt on Android project, I had to do a lot of debugging. This way I found that debugging Qt apps on Android using QtCreator was ok, but it had some issues, which was kinda frustrating.

  • Discover – Easily Install Software on KDE Neon Desktop

    KDE Discover is an Open Source GUI app installer that comes packaged with KDE Neon. It was particularly built from the ground up to be compatible with other modern Linux distros with emphasis on beauty and convenience.

    KDE Discover was also designed to allow for an intuitive User Experience as it features a clean and clear layout with a high readability value which makes it easy to browse, search for, install, and uninstall applications.

  • Almost 10 years of Plasma-Desktop

    Last week I was at work and start to listen my boss said: “We need to show this to our director”. So I went to my coworker table to see what was happening. So they were using Gource to make a video about the git history of the project. Gource is a software version control visualization tool. So that triggered in my mind some memories about a friend talking about Python and showing how the project as grow in this past years, but I never discovered about the tool that made that amazing video.

    So well, I started to make some Gource videos, and because my love about KDE Community, why not make one about it?

Graphics: XRGEARS and Arcan's Latest

  • XRGEARS: Infamous "Gears" Now On VR Headsets With OpenHMD, Vulkan
    Well, the virtual reality (VR) demo scene is now complete with having glxgears-inspired gears and Utah teapot rendering on VR head mounted displays with the new XRGEARS. Kidding aside about the gears and teapot, XRGEARS is a nifty new open-source project with real value by Collabora developer Lubosz Sarnecki. XRGEARS is a standalone VR demo application built using the OpenHMD initiative for tracking and Vulkan for rendering. XRGEARS supports both Wayland and X11 environments or even running off KMS itself. This code also makes use of VK_EXT_direct_mode_display with DRM leasing.
  • Arcan versus Xorg – Approaching Feature Parity
    This is the first article out of three in a series where I will go through what I consider to be the relevant Xorg feature set, and compare it, point by point, to how the corresponding solution or category works in Arcan. This article will solely focus on the Display Server set of features and how they relate to Xorg features, The second article will cover the features that are currently missing (e.g. network transparency) when they have been accounted for. The third article will cover the features that are already present in Arcan (and there are quite a few of those) but does not exist in Xorg.
  • Arcan Display Server Is Nearing Feature Parity With The X.Org Server
    The Arcan display server, which started off years ago sounding like a novelty with being a display server built off a game engine in part and other interesting features, is nearing feature parity with the X.Org Server. While most hobbyist display server projects have failed, Arcan has continued advancing and with an interesting feature set. Recently they have even been working on a virtual reality desktop and an interesting desktop in general. Arcan is getting close to being able to offering the same functionality as a traditional X.Org Server. If you are interested in a lengthy technical read about the differences between Arcan and X.Org, the Arcan developers themselves did some comparing and contrasting when it comes to the display support, windowing, input, font management, synchronization, and other areas.

CoC/Systemd Supremacy Over Linux Kernel

  • New Linux Code of Conduct Revisions: CoC Committee Added Plus Interpretation & Mediator
    The Linux Code of Conduct introduced last month that ended up being quite contentious will see some revisions just ahead of the Linux 4.19 stable kernel release. Greg Kroah-Hartman has outlined the planned changes as well as a new Code of Conduct Interpretation document. In the weeks since the Linux kernel CoC was merged, various patches were proposed but none merged yet. It turns out Greg KH was working in private with various kernel maintainers/developers on addressing their feedback and trying to come up with solutions to the contentious issues in private.
  • Some kernel code-of-conduct refinements
    Greg Kroah-Hartman has posted a series of patches making some changes around the newly adopted code of conduct. In particular, it adds a new document describing how the code is to be interpreted in the kernel community.
  • Systemd Adds Feature To Fallback Automatically To Older Kernels On Failure
    Systemd's latest feature is the concept of "boot counting" that will track kernel boot attempts and failures as part of an automatic boot assessment. Ultimately this is to provide automatic fallback to older kernels should a newer kernel be consistently failing. The feature was crafted over the past few months by Lennart Poettering himself to provide a way when making use of systemd-boot on UEFI systems it can automatically fallback to an older kernel if a newer kernel is consistently causing problems. This is treated as an add-on to the Boot Loader Specification. The systemd boot assessment is designed that it could also be used by non-UEFI systems and other boot platforms.

ODROID 'Hacker Board'

  • ODROID Rolling Out New Intel-Powered Single Board Computer After Trying With Ryzen
    While ODROID is most known for their various ARM single board computers (SBCs), some of which offer impressive specs, they have dabbled in x86 SBCs and on Friday announced the Intel-powered ODROID-H2. In the announcement they mentioned as well they were exploring an AMD Ryzen 5 2500U powered SBC computer, which offered fast performance but the price ended up being prohibitive. After the falling out with Ryzen over those cost concerns, they decided to go ahead with an Intel Geminilake SoC. Geminilake is slower than their proposed Ryzen board, but the price was reasonable and it ends up still being much faster than ODROID's earlier Apollolake SBC.
  • Odroid-H2 is world’s first Gemini Lake hacker board
    Hardkernel unveiled the Odroid-H2, the first hacker board with an Intel Gemini Lake SoC. The Ubuntu 18.10 driven SBC ships with 2x SATA 3.0, 2x GbE, HDMI and DP, 4x USB, and an M.2 slot for NVMe. When the Odroid-H2 goes on sale in November at a price that will be “higher than $100,” Hardkernel will join a small group of vendors that have launched a community backed x86-based SBC. This first open spec hacker board built around Intel’s new Gemini Lake SoC — and one of the first Gemini Lake SBCs of any kind — follows earlier Arm-based Odroid winners such as the Odroid-C2 Raspberry Pi pseudo clone and the octa-core Odroid-XU4.
