  • KDE at Ohio Linux Fest 2017

    It's been a long time! I have been very busy with my PhD but this particular semester I have more time to volunteer to KDE so I thought the fact that the Ohio Linux Fest was happening close to me was a good opportunity to do some KDE promo in USA.

    I ended up being caught up in the middle of many deadlines just before the event, so I had very little time to prepare the promo material that I was going to show. I was somehow able to modify some Plasma artwork that was available for ISO sizes just in time for printing for the Ohio Linux Fest. I also borrowed a laptop with modest hardware, where I had Neon 5.10 running.

  • Energy-Saving Plasma

    I’m very pleased with the results: An idle Plasma Desktop doesn’t wake up the CPU, which is something we worked on avoiding for years. Furthermore, idling, I get a battery drain rate of less than 4 watt, which is pretty exceptional. Bottom line: Our work hasn’t been in vain and shows that Plasma is pretty well optimized to get the most out of your battery. This is especially interesting for Plasma Mobile of course, but benefits laptop users as well. It’s a nice example how our work on convergence benefits all users. And polar bears.

GNOME vs KDE: Best Desktop?

Filed under
KDE
GNOME

Even with the introduction of new Linux desktop environments over the years, GNOME and KDE remain major players in the Linux desktop arena. Both desktops are mature, and come with a rock solid history of innovation and have legions of users.

In this article, I’ll compare GNOME and KDE’s stark differences. I’ll also explain the strengths and weaknesses between the two desktops as well.

  • Interview with Emily Wei

    This might have changed in version 3, but I’m still using version two-point-something since my computer can’t quite handle the newest version.

  • KDE Partition Manager 3.2.0

    I have just released versions 3.2.0 of KDE Partition Manager and KPMcore library. Note that if you use Calamares installer you need version 3.1.4 or later, earlier versions of Calamares will not compile against new kpmcore.

  • KMarkdownWebView 0.2.0

    The KMarkdownWebView software is for the rendered display of Markdown documents, using web technologies (native wrapper around a webpage with a JavaScript library which creates HTML from the plain text handed in).

KDE Neon Complete Distro Review

Filed under
KDE
Reviews

It's no secret to anyone: KDE and its latest implementation, Plasma 5, have been my favorite applications and desktop suite for quite some time now. I started GNU / Linux with Gnome 2 that brought Ubuntu Feisty Fawn but quickly jumped to that unknown ocean, full of strange words with the letter K in them, called Kubuntu.
Coming and going, distros and more distros, until you end up trapped by the Chakra magic and its unique environment. As much as I have tried to change this fact in successive attacks of distro hopping. I have not been able to accommodate myself to anyone other than Cinnamon, although I have missed a few features almost exclusive to Plasma. It also happens in reverse, that is, I think that KDE suffers from some things, but in the balance weighs more, by far, the positive than the negative.

KDE/Qt: Qt Desktops, KDE e.V. Board Dinner, KWin/Wayland, Privacy, KTimer, Plasma 5.11 Beta

KDE
  • It’s the Qt showdown

    Qt desktops are many and varied. So one may ask, all right, if you have to choose one, which one? Well, the answer is both complicated and philosophical. First, because taste is subjective, and my immediate answer would be Plasma, hands down. The way it is realized in Kubuntu 17.04 is just awesome. The best Linux has to offer on the market right now.

    But let’s say you want to choose from one of the other available Qt-based desktops. What do you do then? Well, that’s why we’re here, and I’d like to give you a multi-dimensional overview and comparison of these different Qt desktop environments. After all, we talked about them a fair bit recently, so let’s narrow it down, shall we?

  • Come dine with the KDE e.V. board in Berlin in October!

    As has become tradition in recent years, the KDE e.V. board will have an open dinner alongside its in-person meeting in Berlin, Germany on October 14th, at 7 PM.

  • KDE's KWin Running On Wayland Gets Real-Time Scheduling

    When KDE's KWin is acting as a Wayland compositor, there's now a real-time scheduling policy to ensure the graphical system is always responsive.

  • KWin/Wayland goes real time

    Today I landed a change in KWin master branch to enable real time scheduling policy for KWin/Wayland. The idea behind this change is to keep the graphical system responsive at all times, no matter what other processes are doing.

    So far KWin was in the same scheduling group as most other processes. While Linux’s scheduler is completely fair and should provide a fair amount of time to KWin, it could render the system hard to use. All processes are equal, but some processes are more equal than others. KWin – as the windowing system – is to a certain degree more equal. All input and all rendering events need to go through KWin.

    We can now imagine situations where a system can become unusable due to KWin not getting sufficient time slots. E.g. if the user moves the mouse we expect a timely cursor motion. But if KWin is not scheduled the system is quickly starting to lagging. Basically what we expect is that when the mouse moves with the next page flip the cursor must be at the updated position. A page flip happens normally every 16 msec (60 Hz), so if we miss one or two we are in the area where a user visually notices this. For a gamer with a high precision mouse this could be quite problematic already.

  • Privacy Software

    As a means to give our work direction and a clearer purpose, KDE is currently in the process of soul-searching. Here’s my proposal of what we should concentrate and focus on in the coming years. I’d welcome any feedback from the community to make this proposal better, and rally up more support from the community, and others interested.

Qt/KDE: Qt World Summit, GammaRay, Kdenlive, and Krita

Filed under
KDE
  • Lots of lights: Generating cities

    Sometimes data visualization might call for more than a graph - you need to visualize complex data, such as that generated by city lighting, in three dimensions to get the full effect.

    KDAB decided to put together a showcase for the Qt World Summit that allowed us to demonstrate Qt 3D's capabilities as a performant next-generation graphics engine, which can draw thousands of lights and objects simultaneously. This also enabled us to show what modern technologies like Qt 3D can achieve when paired with OpenGL, C++ and custom tooling.

  • GammaRay 2.8.1 Release

    We have released version 2.8.1 of our Qt application introspection tool GammaRay. This release contains a number of important bugfixes as well as support for Qt 5.9.2. Especially if you are experiencing corrupt views or crashes when searching in the object tree, or having trouble attaching to a process on Windows, you want to upgrade to the new version. The same applies to users of bleeding edge Qt versions experiencing build failures.

  • Last week in Kdenlive

    This release is only made available for interested testers and should not be used for production. Please report problems in the categories placed on the phabricator page regarding the AppImage / timeline refactoring branch, we will switch back to the normal bugtracker when the beta release will be ready.

  • Krita 3.3 Open-Source Digital Painting App Released with Better HiDPI Support

    Krita, the cross-platform, open-source and free digital painting tool used by hundreds of thousands of artists worldwide, has been updated today to version 3.3, a point release that adds better HiDPI support and many other improvements.

    Prominent changes of Krita 3.3 include support for the Windows 8 event API to bring native support for the n-trig pen in the Surface line of laptops, as well as other similar notebooks from Acer, Dell or HP, refactored hardware-accelerated display functionality to make Krita use Direct3D indirectly instead of native OpenGL.

  • Last Week Development in Elisa

    I have focused on keyboard navigation and correct handling of focus. Some preliminary work is already integrated with more to come. I hope to soon be able to use Elisa only with the keyboard and am starting to enjoy the progress so far. This is quite different from the last two years where only mouse and touch screen were usable to interact with Elisa.

  • Plasma secrets: task manager tweaks

    Recently, I have been having a lot of fun with the Plasma desktop. It all started with Zesty Zapus, a phenomenal release that redeemed KDE. In fact, I've boldly proclaimed that my next serious box to use Linux will be running Kubuntu, most likely the upcoming 2018 LTS. It hasn't been this merry since roughly 2006 or so. Happy days.

    With so much time and pleasure spent on Kubuntu, I've dubbed the perfect distro, and then, I've also shown you how to deftly pimp it into sweet submission, as well as graced you with a few more tips and tricks that should make your Plasma experience sweeter still. Now, we will discuss another less known feature in this desktop environment, and that's the task manager. Shall we. 

    [...]

    Plasma desktop is way ahead of anything else in the Linux world right now. Yes, there are still glaring issues and annoying bugs, like the file copy timestamp for Samba shares or the ability to play media from remote devices, but overall, it's shaping up to be an excellent product. There's a lot of thought and attention to detail, and layer upon layer of smart, intelligent functionality packaged in an elegant and presentable way. I'm really really liking this.

    Well, hopefully, today's little guide gives you even more reasons to try Plasma. It started with a revelation that is Kubuntu 17.04, then I've shown you how to pimp this desktop for everyday use, and given you a wealth of tricks that should make the experience even more enjoyable. Finally, we have these task manager tweaks. Well, if you have a request for anything else, don't be a stranger. Shout, happy KDE, and may Plasma be with you.

Neon: the naked KDE

Reviews

I had nothing to complain about the technical part of KDE Neon Live run. It was smooth and fast. There were no glitches or unexpected delays (apart from one - I cannot remember the exact details).

However, the lack of the very basic software makes me stop from recommending this distribution to the beginners. It may be a good distribution for those users who know their way in the Linux world well, who are confident in what they need and how to get it themselves.

Do you recognise yourself in the first or the second category of Linux users?

GNOME: WebKit, Fleet Commander, Introducing deviced

  • On Compiling WebKit (now twice as fast!)
    Are you tired of waiting for ages to build large C++ projects like WebKit? Slow headers are generally the problem. Your C++ source code file #includes a few headers, all those headers #include more, and those headers #include more, and more, and more, and since it’s C++ a bunch of these headers contain lots of complex templates to slow down things even more. Not fun.
  • Fleet Commander is looking for a GSoC student to help us take over the world
    Fleet Commander has seen quite a lot of progress recently, of which I should blog about soon. For those unaware, Fleet Commander is an effort to make GNOME great for IT administrators in large deployments, allowing them to deploy desktop and application configuration profiles across hundreds of machines with ease through a web administration UI based on Cockpit. It is mostly implemented in Python.
  • Introducing deviced
    Over the past couple of weeks I’ve been heads down working on a new tool along with Patrick Griffis. The purpose of this tool is to make it easier to integrate IDEs and other tooling with GNU-based gadgets like phones, tablets, infotainment, and IoT devices. Years ago I was working on a GNOME-based home router with davidz which sadly we never finished. One thing that was obvious to me in that moment of time was that I’m not doing another large scale project until I had better tooling. That is Builder’s genesis, and device integration is what will make it truly useful to myself and others who love playing with GNU-friendly gadgets.

  • Look, new presets! Another Krita 4 development build!
    We’ve been focusing like crazy on the Krita 4 release. We managed to close some 150 bugs in the past month, and Krita 4 is getting stable enough for many people to use day in, day out. There’s still more to be done, of course! So we’ll continue fixing issues and applying polish for at least another four weeks. One of the things we’re doing as well is redesigning the set of default brush presets and brush tips that come with Krita. Brush tips are the little images one can paint with, and brush presets are the brushes you can select in the brush palette or brush popup. The combination of a tip, some settings and a smart bit of coding! Our old set was fine, but it was based on David Revoy‘s earliest Krita brush bundles, and for Krita 4 we are revamping the entire set. We’ve added many new options to the brushes since then! So, many artists are working together to create a good-looking, useful and interesting brushes for Krita 4.

Software: GIMP, Spyder, SMPlayer

  • Five free photo and video editing tools that could save burning a hole in your pocket and take your creativity to the next level
    GIMP stands for the Gnu Image Manipulation Program and is the first word that people usually think about when it comes to free image editors. It’s a raster graphics editor, available on multiple platforms on PC. It has a similar interface to Photoshop: you have your tools on one side, there’s an option for your tool window and then you have your layers window on another side. Perhaps one of the most useful features of GIMP is the option of plugins. There is a wide database for them and there’s a plugin for almost any task you might need to carry out. GIMP is extremely extensive, and it’s the choice of the FOSS community, thanks to the fact that it’s also open source. However, there are also some disadvantages. For example, GIMP has no direct RAW support yet (you have to install a plugin to enable it, which means a split workflow). It also has quite a bit of a learning curve as compared to Photoshop or Lightroom.
  • Introducing Spyder, the Scientific PYthon Development EnviRonment
    If you want to use Anaconda for science projects, one of the first things to consider is the spyder package, which is included in the basic Anaconda installation. Spyder is short for Scientific PYthon Development EnviRonment. Think of it as an IDE for scientific programming within Python.

    SMPlayer is a free media player created for Linux and Windows, it was released under GNU General Public License. Unlike other players it doesn't require you to install codecs to play something because it carries its own all required codecs with itself. This is the first release which now support MPV and some other features such as MPRIS v2 Support, new theme, 3D stereo filter and more. It uses the award-winning MPlayer as playback engine which is capable of playing almost all known video and audio formats (avi, mkv, wmv, mp4, mpeg... see list).
