KDE

The State of Plasma

Filed under
KDE

Over the years, my experience with KDE can best be described as a rollercoaster – on ice, with rocket thrusters. KDE3.5 was a great release, followed by a somewhat mellow, emotionally curbed KDE4, which took years blossoming, and then when it finally gained solid form, it was replaced with KDE5, or rather, Plasma 5.

Since 2014, Plasma has kept me entertained and disappointed in equal measures. At some point, I had it crowned my favorite desktop, and then it went downhill steeply, fast, struggling to recover. Not helping was the slew of bugs and regressions across the distro space, which exacerbated the quality of Plasma and what it could show the world. Today, I would like to explore Plasma from a different angle. Not from the user perspective, but usability perspective. AKA Everything What Plasma Does. After me.

KDE in Slackware, Cutelyst 1.4.0 Ready

  • KDE 5_17.02 for Slackware-current is available

    I am happy to announce my February 2017 release of the ‘ktown’ packages: KDE 5_17.02. What you get in this new release is: KDE Frameworks 5.31.0, Plasma 5.9.2 and Applications 16.12.2. All built on top of Qt 5.7.1.
    Soon, I will compile this version of Plasma 5 on Slackware 14.2 (only 64bit) as well, but I gave priority last few days to the new LibreOffice packages and a new PLASMA5 Live image. The packages that I am releasing today are for Slackware-current only (both 32bit and 64bit). As stated in my previous post, I will no longer be releasing Plasma 5 packages for 32bit Slackware 14.2.

  • New Slackware PLASMA5 Live ISO (with Plasma 5.9)

    To conclude this week’s batch of updates in my repositories I have re-generated the ISO for PLASMA5 Slackware Live Edition – it is based on liveslak 1.1.6.2 and using Slackware-current dated “Mon Feb 13 06:21:22 UTC 2017“.

    If you already use PLASMA5 Live on a USB stick that you do not want to re-format, you should use the “-r” parameter to the “iso2usb.sh” script. The “-r” or refresh parameter allows you to refresh the liveslak files on your USB stick without touching your custom content.

  • Cutelyst 1.4.0 released, C100K ready.

    Thanks to the last batch of improvements and with the great help of jemalloc, cutelyst-wsgi can do 100k request per second using a single thread/process on my i5 CPU. Without the use of jemalloc the rate was around 85k req/s.

    This together with the EPoll event loop can really scale your web application, initially I thought that the option to replace the default glib (on Unix) event loop of Qt had no gain, but after increasing the connection number it handle them a lot better. With 256 connections the request per second using glib event loop get’s to 65k req/s while the EPoll one stays at 90k req/s a lot closer to the number when only 32 connections is tested.

  • KDE Applications 17.04 Announced for April 20, Here's the Final Release Schedule

    KDE developer Albert Astals Cid announced that the release date of the upcoming KDE Applications 17.04 open-source software suite for KDE Plasma desktop environments, along with the final release schedule.

    We were just wondering when KDE Applications 17.04 will be released when the current KDE Applications 16.02 series received its second maintenance update, and we were right to believe at the point in time that the final release is coming in April, and, according to the release schedule, it looks like KDE Applications 17.04 lands April 20, 2017.

  • KDE Applications 17.04 To Be Released 20 April

    The release schedule for the upcoming KDE Applications 17.04 has been firmed up.

    The KDE Applications 17.04 release is scheduled to happen on 20 April. For that to happen, the planned dependency freeze is 16 March, the beta release on 23 March, KDE applications 17.04 Release Candidate on 6 April, and prepping for the actual 17.04 release beginning on 13 April.

  • KDE Plasma 5.9.2 Desktop Rolls Out on Valentine's Day with Multiple Bug Fixes

    It's Valentine's Day, and to celebrate this important event, the KDE developers demonstrate their love for KDE Plasma users by bringing them a new maintenance update for the KDE Plasma 5.9 desktop environment.

    Yes, we're talking about KDE Plasma 5.9.2, the second point release to the latest KDE Plasma 5.9 desktop, which launched just two weeks ago for various GNU/Linux distributions, including KDE Neon and Arch Linux. Because of the new, fast release cycle, you see this new version just one week after the first update, namely KDE Plasma 5.9.1.

  • An Early Qt 5.9 Alpha Snapshot: Qt 5.9 Packing A Ton Of Features

    While Qt 5.8 was released less than one month ago, the Qt 5.9 Alpha release is on approach for landing.

    Jani Heikkinen today announced the first Qt 5.9 Alpha snapshot. This isn't the formal Qt 5.9 Alpha release, but will become the official Alpha source package if there isn't anything important that's missing. Hit up that mailing list link if you are interested in testing.

  • KDE's Plasma Discover Package Manager to Support Flatpak Packages and Repos

    It looks to us like Flatpak, the open-source application sandboxing and distribution framework for GNU/Linux systems is on its way to becoming the norm on most distributions.

    Not only that GNOME Software offers support for Flatpak runtimes, but it appears that KDE's Plasma Discover graphical package manager will do too, as KDE developer Jan Grulich reports today on the upcoming availability of a Flatpak backend to implement support for handling Flatpak packages and repositories in the app.

  • KDE Discover flatpak backend

    As some of you might already know, I’ve been focusing lately on Flatpak and its integration into KDE. You can check my work on Flatpak KDE portals, which are being currently included in our KDE runtimes and repositories were migrated to KDE git so there has been made some progress since last time I talked about them. Recently I started looking into adding Flatpak support to KDE Discover, to have same support for Flatpak as Gnome has with gnome-software. From the begining it was a nightmare for me as I have never used any glib based library so that slowed me down little bit. I also went through gnome-software code to understand how flatpak integration is done there to get some inspiration. Things went well since then and I have already quite nice stuff to share with you. We currently support most common functionality, like listing available/installed flatpak applications in Discover with possibilities to install/remove/update and of course launch them. We also support flatpak bundles and flatpakref files already.

Review: KDE neon 5.9.1

Reviews

It has been a while since I've done a review of a Linux distribution. Lately, I've seen a few reviews of KDE neon (the second word being intentionally written in lowercase), and some of them have praised it as being much better than Kubuntu (the traditionally KDE spin of Ubuntu). That got my attention, so I figured I should check it out.

  • Native look and feel

    We know that many Qt users want controls styled with a native look-and-feel. But offering that on platforms with no public styling API, is hard. A classic approach is to take snapshots of the native controls, tweak them, and use them as foreground or background in our own controls. Which is somewhat OK for static appearances. But when animations and transitions are involved, static pixmaps will only take you half the way. And since an OS can change style from one update to the next, taking snapshots runtime is risky. Using pre-grabbed snapshots is also something we don’t do because of legal considerations.

  • Glowing Qt Charts

    Have you ever had the need to visualize data graphically and add some ‘wow’-effect to it? I’m currently helping out with the development of a demo application, where we have some charts to visualize data received from sensors. Naturally, the designer wants the charts to be visually appealing.

  • Does KDE.org look funny to you?

    Our stalwart KDE homepage, which has been with us for several years, has, after serving us well, finally been retired.

    The new KDE.org homepage, using the new theme “Aether”, is only the first step of a much longer journey to unify the disparate KDE websites. KDE.org and its surrounding network is made of many parts: forums, wikis, feed aggregates, custom solutions, etc; beyond the homepage each of these will need to be updated. It will be a long road, but the modernization is due.

  • Kanboard to Phabricator

    A while ago KDE migrated our todo management from Kanboard to Phabricator to reduce the amount of software our System Administrators have to manage and maintain. In KDE neon we did this move already ahead of time so I happened to have a primitive migration script at hand, ultimately making me the person to auto migrate everyone’s todos.

  • FOSDEM 2017 & the QtWayland Compositor Framework

    This will be a rather short blog post but since I completely missed to making it before this year’s FOSDEM, just let me give you a short hint to my current talk: This year, for the first time, I submitted a talk to the Embedded & Automotive DevRoom. If you think that this sounds crazy, actually, what we see on modern embedded devices, like in cars or in even bigger machines, this tends gain a similar complexity like the good old Linux desktop environments. In terms of multiple processes, window compositing and UI requirements, a lot of such demands are already on the table…

Kdenlive 16.12.2 released

KDE

The second maintenance release of the 16.12 series is out, part of KDE Applications 16.12.2.

This release fixes startup crashes with some graphic cards, as well as some fixes to MOVIT (GPU effect processing) and minor stability issues. The Appimage version as well as our PPA’s were updated, check our download section for instructions. An updated Windows version will be released in the next days. This is a relatively small update since all our efforts are currently focused on the timeline refactoring branch which will bring professional grade new features and more stability. Stay tuned for more news!

  • KDE Neon to Support Snap Apps in Plasma Discover

    Ubuntu-based KDE Neon is one the Linux distros we’re most excited for this year — and with good reason. The distro combines the stability of Ubuntu’s latest LTS foundations with the latest (and, if you want it, bleeding edge) KDE applications and Plasma desktop releases.

  • Adoption of Flatpak vs Snap

    Given these results alone, I’m quite frankly pretty puzzled how the jury could still be out and that’s completely ignoring the centralized nature of Snap. Distributing AppImages via Steam makes more sense than Snap (Steam has the same centralized nature as Snap). Not only does every somewhat mainstream distribution ship Steam in some non-free repo, it would also allow us to distribute applications to Windows and macOS.

  • The State Of Flatpak vs. Snaps On Various Linux Distributions

    Motivated by KDE Plasma Leaning Towards Focusing On Flatpak Over AppImage/Snaps and this lengthy, contentious forum thread, a KDE contributor has taken a closer look at the Flatpak versus Snaps versions available in different Linux distributions.

    KDE contributor Markus Slopianka sought to clarify the adoption of Flatpak vs. Snap in modern Linux distributions. He looked at the state of Snap and Flatpak in the releases of Arch, Debian, Fedora, Gentoo, Mageia, openSUSE, and Ubuntu.

NGINX moves towards web server dominance with European expansion

Web server NGINX powers more than 317 million sites around the globes, and has rapidly replaced Apache as the engine of choice for the world's 100,000 busiest, counting Netflix, Airbnb and Dropbox among its high-profile clients. NGINX Inc - the company set up to commercialise the open source technology - has now set its sights on developing its business in Europe and recently opened a new EMEA headquarters in Cork, Ireland as a launching point to the region. NGINX began life as a web server written by a Russian engineer called Igor Syosev in 2002 while he was working as a system administrator for the portal site Rambler. Read more
