GNOME Desktop/GTK: fwupdate, LVFS and More

Filed under
GNOME
  • fwupdate is {nearly} dead; long live fwupd

    If the title confuses you, you’re not the only one that’s been confused with the fwupdate and fwupd project names. The latter used the shared library of the former to schedule UEFI updates, with the former also providing the fwup.efi secure-boot signed binary that actually runs the capsule update for the latter.

  • Affiliated Vendors on the LVFS

    We’ve just about to deploy another feature to the LVFS that might be interesting to some of you.

    [...]

    The LVFS administrator can now mark other vendors as “affiliates” of other vendors. This gives the ODM permission to upload firmware that is “owned” by the OEM on the LVFS, and that appears in the OEM embargo metadata. The OEM QA team is also able to edit the update description, move the firmware to testing and stable (or delete it entirely) as required. The ODM vendor account also doesn’t have to appear in the search results or the vendor table, making it hidden to all users except OEMs.

  • Flatpak in detail, part 3

    The previous in this series looked at runtimes and filesystem organization. Here, we’ll take a look at the flatpak sandbox and explore how the world looks to a running flatpak app.

    [...]

    But how does GTK+ find out that is being used inside a sandbox?

    It looks for a file called .flatpak-info which flatpak places in the filesystem root of every sandbox. This file is not just a marker, it contains some useful information about the details of the sandbox setup, and is worth looking at. Some apps show information from here in their about dialog.

Qt/KDE: QtCon Brasil 2018, Qt 5.12 and Qt Creator 4.8.0 Beta 2

  • Talking about Qt and Computer Vision at QtCon Brasil 2018
    I had the opportunity to participate in QtCon Brasil 2018 as a speaker during the last weekend. It happened in São Paulo, which is a city that I haven’t visited for a long time. My talk was about the integration of Qt applications and Computer Vision, specially focused on the mobile environment with QtQuick and QML. During my presentation, I was focused on introducing some concepts to the people who just have heard or never had contact with Computer Vision. I talked a little bit about OpenCV, including an brief explanation about its modules and how they work, and I presented a little example of object recognition application made with QML (the code is available in the repository).
  • Qt Quick Performance Improvements with Qt 5.12 LTS
    Qt 5.9 LTS already shows a great improvement of the overall performance compared to the previous long-term supported Qt 5.6 LTS release. These are summarized in a blog post about Performance Improvements with Qt 5.9 LTS and Qt Quick Performance Improvements on 64-bit ARM. With Qt 5.12 LTS we have continued to tune these further and taken a deeper look into the areas of QML engine memory consumption and JavaScript performance.

  • Qt 5.12 Lowering The QML Memory Consumption, Better JavaScript Performance
    As part of The Qt Company's ongoing improvements to their tool-kit and with Qt 5.12 being an LTS release, this cycle they focused a lot on improving the performance. Qt 5.12 LTS will be releasing in the next few weeks and as part of their performance push they have been working to lowering the memory consumption of the QML engine. The QML data structures have been optimized to reduce their size and better handling around cached objects.
  • Qt Creator 4.8 Beta2 released
    We are happy to announce the release of Qt Creator 4.8.0 Beta2! This release comes with the many fixes that we have done since our first Beta release. Additionally we upgraded the LLVM for the Clang code model to version 7.0, and our binary packages to the Qt 5.12 prerelease.
