  • Release of Kube 0.1.0

    It’s finally done! Kube 0.1.0 is out the door.

    First off, this is a tech preview really and not meant for production use.

  • So what is Kube? (and who is Sink?)

    Kube is further developed in coordination with Roundcube Next, to achieve a consistent user experience across the two interfaces and to ensure that we can collaborate while building the UX.

    A roadmap has been available for some time for the first release here, but in the long run we of course want to go beyond a simple email application. The central aspects of the the problem space that we want to address is communication and collaboration as well as organization. I know this is till a bit fuzzy, but there is a lot of work to be done before we can specify this clearly.

  • KDE's Kube Mail/PIM Client Does Its First Tech Preview Release

    Today marks the release of KDE's new Kube 0.1 project, the first tech preview (pre-production) release of this experimental Kontact based on Qt Quick and Akonadi-Next.

    Kube is self-described by its GitHub repository as "a personal information and collaboration application currently in its early stages of development. It uses Sink for data access and synchronization, and leverages the KDE PIM codebase where possible."

  • Plasma 5.10: Folder View as default desktop mode

    To set the stage, we need to briefly recap some of the problems with the KDE 3.x desktop that (among others) Plasma initially set out to solve.

  • KDE Plasma 5.10 Desktop Environment to Feature Folder View as Default Mode

    See the screenshot on the right? That's how your KDE Plasma 5 desktop environment will look like when you upgrade this summer to the KDE Plasma 5.10 release, which will enter development in early May.

    KDE developer Eike Hein is announcing that the KDE Plasma 5.10 desktop environment will come with a brand-new look (sort of). According to the developer, the Folder View will be used by default for the upcoming release instead of that Desktop widget you're probably removing every time you reinstall your KDE-based distribution.

  • GNOME 3.24 Desktop Environment Prepares for March 22 Release, New Beta Is Out

    With a one-day delay, the GNOME Project, through Matthias Clasen, was proud to announce the release and immediate availability for download of the second and last Beta of the forthcoming GNOME 3.24 desktop environment.

    GNOME 3.24 Beta 2 arrives only two weeks after the first Beta release, and brings with it numerous updated core components and applications that are usually shipped under the GNOME Stack umbrella. The technical version number is GNOME 3.23.91, and can be downloaded from the usual places by early adopters and public beta testers.

  • GNOME's gThumb 3.6 Open-Source Image Viewer to Launch with Numerous New Features

    Paolo Bacchilega, the developer of the gThumb open-source and free image viewer and browser application designed specifically for the GNOME desktop environment kicked off the development of the next major version, gThumb 3.6.

    A first snapshot is now available for download, gThumb 3.5.1, and ships with numerous new features and improvements. For example, there's now double-click activation support, a brand-new zoom popover that includes a bunch of zoom commands, as well as a zoom slider, and a color picker.

  • The Novelty of KDE Neon

    The good folks at KDE managed to engage a market of Linux desktop users underserved by other distribution models. Or, maybe it’s just me.

    KDE has a long history in the desktop ecosystem. It was the first Linux desktop I was exposed to back in 2006. Back then, it was on OpenSUSE and it was clean and functional. For some reason after that, installing KDE had never really appealed to me. I’ve tested it out briefly when poking around at what the OpenSUSE guys were doing and I’ve run Kubuntu for brief snippets. For years, I’ve been trying to find out what type of desktop user I am and which distro fits my needs.

  • Tracking KDE Frameworks and Qt

    The KDE-FreeBSD team bumped Qt to 5.7.1 and KDE Frameworks to 5.31.0 in official ports last week, so we’re fairly up-to-date in that department. On FreeBSD, we still fully support Qt4 next to Qt5, so some of the delay in getting this stuff in is due to some shuffling of install locations. In particular, we’ve added qt-chooser in this round of updates, so that qmake is qmake — and no longer qmake-qt4 or some other suffixed binary. We use qt-chooser to switch out one or the other. Checking that this doesn’t break anything else — or at least making sure that everything still compiles — is what took the most time this round of updates.

  • Simple Menu Launcher for KDE Plasma 5.9

    Following "United" theme, there is also "Simple Menu" launcher for KDE Plasma 5.9. It's minimal, a smaller form of full screen menu; it's also clean, showing all applications at once. Honestly, it's UI is similar to Pantheon Menu in elementary OS but including categories. If you like horizontal-oriented menu, Simple Menu is suitable for you. It's available to install from KDE Store. Thanks to Sho for creating Simple Menu.

  • Telegram desktop client for flatpak #2

    Some time ago I posted a blog post about how I packed telegram desktop client for flatpak. I’ve been updating it since then in some reasonable intervals as I don’t have time to update it more often and mostly because the telegram client’s build system breaks my build quite oftenly. Recently I discovered that someone managed to patch telegram to use system Qt libraries instead of building own patched Qt and building linking it statically. After some time I managed to adjust those patches and make them work with my build which allows me to use Qt from KDE runtimes. Here are new instructions how to get this work:

  • Building the latest greatest for Android AArch64 (with Vulkan teaser)

    Let’s say you got a 64-bit ARM device running Android. For instance, the Tegra X1-based NVIDIA Shield TV. Now, let’s say you are also interested in the latest greatest content from the dev branch, for example to try out some upcoming Vulkan enablers from here and here, and want to see all this running on the big screen with Android TV. How do we get Qt, or at least the basic modules like QtGui, QtQuick, etc. up and running on there?

    WebGL Streaming is optimized for Qt Quick and allows you to run remote Qt Quick applications in a browser.

Recreating the PCLinuxOS Full Monty with KDE Plasma Activities

Filed under
KDE
PCLOS

When I recently wrote about the new PCLinuxOS release, I was a bit disappointed to find that the Full Monty version had been laid to rest. I'm sure there were a lot of good reasons for this decision, and I have no quarrel with it. But it still made me a bit sad, because I have always kept the Full Monty on at least one of my systems (it is currently on my Acer All-In-One desktop), and I often showed it to people who were curious about Linux, as an example of its breadth, depth and flexibility.

So I decided that it might be a useful exercise for me to try to create the equivalent of the Full Monty desktop starting from the latest PCLinuxOS KDE5 distribution. There are two major features which distinguish the Full Monty desktop - it had six virtual desktops, each of which was dedicated to a specific use, and it had lots and lots and lots of packages installed. The desktops looked like this:

  • Best practices for guiding new coders

    As the new year progresses, many free and open source projects are turning their attention to various formalized mentoring programs, such as Mozilla's Winter of Security, Outreachy, and (the program with my favorite name) the X.Org Endless Vacation of Code. Patterned after the success of Google's Summer of Code, these programs give many new programmers a chance to gain firsthand experience working within successful FLOSS (Free/Libre Open Source Software) projects and the projects themselves access to fresh talent.

  • Fedora 25 KDE: disappointing experience

    Fedora is not a frequent guest on the review deck of Linux notes from DarkDuck blog. The most recent review was of Fedora 22 back in July 2015. That was a review of the GNOME version, the most native for Fedora.

    You are probably aware of the tight link between the GNOME project and RedHat, the Fedora Project main sponsor.

    So, the past couple of weeks I spent a bit of time here and there on trying to see if it is possible.

  • QStringView Diaries: Advances in QStringLiteral

    This is the first in a series of blog posts on QStringView, the std::u16string_view equivalent for Qt. You can read about QStringView in my original post to the Qt development mailing-list, follow its status by tracking the “qstringview” topic on Gerrit and learn about string views in general in Marshall Clow’s CppCon 2015 talk, aptly named “string_view”.

  • Making Movies with QML

    One of the interesting things about working with Qt is seeing all the unexpected ways our users use the APIs we create. Last year I got a bug report requesting an API to set a custom frame rate for QML animations when using QQuickRenderControl. The reason was that the user was using QQuickRenderControl as an engine to render video output from Qt Quick, and if your target was say 24 frames per second, the animations were not smooth because of how the default animation driver behaves. So inspired by this use case I decided to take a stab at creating such an example myself.
