  • QtCon Keynote: Software as a Public Service

    QtCon is happy to welcome Julia Reda, the closing keynote speaker. Member of the European Parliament for the Pirate Party and Vice-Chair of the Greens/European Free Alliance. Reda's legislative focus is on copyright and internet policy issues.

    As a member of the European Parliament and together with Max Andersson, Julia Reda initiated the pilot project “Governance and quality of software code – Auditing of free and open source software” in 2014 as a reaction to the so-called “heartbleed” bug in OpenSSL. The idea turned into the pilot-project "Free and Open Source Software Auditing“ (FOSSA) that is aiming at improving the security of those Free Software programs that are in use by the European Commission and the Parliament.

  • KScreen-Doctor Will Help KDE Developers Improve Multi-Screen Plasma

    Also helping KDE developers in their multi-screen efforts is a centralized activity log in KScreen with Plasma 5.8 and the ability to easily create virtual screens in Wayland for reproducing issues without real hardware.

  • Multisceen in Plasma: Improved tools and debugging

    Plasma 5.8 will be our first long-term supported release in the Plasma 5 series. We want to make this a release as polished and stable as possible. One area we weren’t quite happy with was our multi-screen user experience. While it works quite well for most of our users, there were a number of problems which made our multi-screen support sub-par.
    Let’s take a step back to define what we’re talking about.

  • Linux Mint 18 KDE Beta released

    Clement Lefebvre, head of the Linux Mint project, has announced the availability of the Linux Mint 18 Sarah KDE edition. The KDE edition is the final official spin to get a beta release in the Mint 18 series. What is interesting about the KDE version this cycle is that users running Mint 17.3 KDE won't be able to upgrade to 18 because of the inclusion of Plasma 5, which is “considered a different desktop.”

  • Linux Mint 18 "Sarah" KDE Edition Beta Officially Released Based on Ubuntu 16.04

    Clement Lefebvre has had the great pleasure of announcing the official availability of the Beta release of the upcoming Linux Mint 18 "Sarah" KDE Edition operating system.

    A couple of days ago we had an exclusive first look at Linux Mint 18 "Sarah" KDE Edition, thanks to a news tip from one of our regular readers, but we also gave users the possibility of download the ISO images and take the upcoming GNU/Linux distribution for a test drive on their personal computers so they can see for themselves what's new.

  • Krita 3.0.1 Alpha Builds

    Last week the merge window closed and Krita entered a four week stabilization phase. Several very interesting branches were merged, with features ranging from a new head-up-display for quickly changing brush settings, a wavelet filter, a threshold filter, to a an upgrade for all number entry boxes: those support maths now! Sadly, we haven’t managed to dot all the i’s on the video-export branch for saving animated gifs and videos, so that’s not in.

  • Queueing up for Plasma 5.8

    It’s been too long since I’ve posted on Planet… I missed you! But despite my slothish activity there are rituals to be followed, and so comes a wallpaper for Plasma 5.8;

    Probably the first thing I’ll mention is that the Plasma 5.8 wallpaper will be shipping with a 4K UHD version. The last wallpaper was meant to have a 4K version, but it simply didn’t happen. Seemingly everyone is beginning to enjoy screens with high pixel densities, so it’s about time we shipped wallpapers to match, and it’s a fun bullet-point for an LTS release.

  • Space Left at the (Non)Party Flat at Akademy/QtCon
  • Conferences I will attend in the next two months
  • Akademy is this year at QtCon along with FSF-E, Qt, VLC and others.

  • Akademy and QtCon -- and the future of QFuture
  • LabPlot is comfortable with FITS

    So we are here, GSoC 2016 is officially over, it's time for the final evaluations, so this will be a closing post for this GSoC. I've learned many things while I was working on my project and I'm really thankful to my mentors, Stefan and Alexander (not officially my mentor, but we talked many times and he helped me many times too). I'll be happy to help in integration of this project in the next release of LabPlot Smile

  • Peruse 1.1 "The Cuppa Release"

    Slightly later than the 21st of June this year, the inaugural release of the Peruse comic book reader was made, and received with while not wide spread excitement, then certainly with mostly positive comments (and some very good suggestions). If you are a software developer yourself, you will know exactly how much this means to me. If you are not: This is what sustains us, what encourages us to continue working on the things we do. Thank you all very much!

    Here we are! Google Summer of Code is over and KStars on Windows project is done. It was truly an incredible summer and I am grateful for the opportunity I was given to work on such a great project and learn so much from my mentor, Jasem Mutlaq.

  • Gsoc 2016: Sum up

    Actually Gsoc didnt take me a lot of time but sometimes I still feel burnt out for some reasons. I read a blog post of another Kde – Gsoc student and she also mentioned about the stressful and depression. I think it is shadow part of the IT industry. And we student havent learnt how to deal with it (stress) yet when it comes to real (paid) projects.

  • Isn’t the end, it’s just the beginning – Google Summer of Code 2016

    Tomaz hassled me into submitting a project to Google Summer of Code, a project that until then I had never heard of in my life. KDE was chosen to be one of the communities to be able to host students and projects for KDE entire environment be improved.

Games for GNU/Linux

  • Why GNU/Linux ports can be less performant, a more in-depth answer
    When it comes to data handling, or rather data manipulation, different APIs can perform it in different ways. In one, you might simply be able to modify some memory and all is ok. In another, you might have to point to a copy and say "use that when you can instead and free the original then". This is not a one way is better than the other discussion - it's important only that they require different methods of handling it. Actually, OpenGL can have a lot of different methods, and knowing the "best" way for a particular scenario takes some experience to get right. When dealing with porting a game across though, there may not be a lot of options: the engine does things a certain way, so that way has to be faked if there's no exact translation. Guess what? That can affect OpenGL state, and require re-validation of an entire rendering pipeline, stalling command submission to the GPU, a.k.a less performance than the original game. It's again not really feasible to rip apart an entire game engine and redesign it just for that: take the performance hit and carry on. Note that some decisions are based around _porting_ a game. If one could design from the ground up with OpenGL, then OpenGL would likely give better performance...but it might also be more difficult to develop and test for. So there's a bit of a trade-off there, and most developers are probably going to be concerned with getting it running on Windows first, GNU/Linux second. This includes engine developers.
  • Why Linux games often perform worse than on Windows
    Drivers on Windows are tweaked rather often for specific games. You often see a "Game Ready" (or whatever term they use now) driver from Nvidia and AMD where they often state "increased performance in x game by x%". This happens for most major game releases on Windows. Nvidia and AMD have teams of people to specifically tweak the drivers for games on Windows. Looking at Nvidia specifically, in the last three months they have released six new drivers to improve performance in specific games.
  • Thoughts on 'Stellaris' with the 'Leviathans Story Pack' and latest patch, a better game that still needs work
  • Linux community has been sending their love to Feral Interactive & Aspyr Media
    This is awesome to see, people in the community have sent both Feral Interactive & Aspyr Media some little care packages full of treats. Since Aspyr Media have yet to bring us the new Civilization game, it looks like Linux users have been guilt-tripping the porters into speeding up, or just sending them into a sugar coma.
  • Feral Interactive's Linux ports may come with Vulkan sooner than we thought
  • Using Nvidia's NVENC with OBS Studio makes Linux game recording really great
    I had been meaning to try out Nvidia's NVENC for a while, but I never really bothered as I didn't think it would make such a drastic difference in recording gaming videos, but wow does it ever! I was trying to record a game recently and all other methods I tried made the game performance utterly dive, making it impossible to record it. So I asked for advice and eventually came to this way.

Leftovers: Software

  • DocKnot 1.00
    I'm a bit of a perfectionist about package documentation, and I'm also a huge fan of consistency. As I've slowly accumulated more open source software packages (alas, fewer new ones these days since I have less day-job time to work on them), I've developed a standard format for package documentation files, particularly the README in the package and the web pages I publish. I've iterated on these, tweaking them and messing with them, trying to incorporate all my accumulated wisdom about what information people need.
  • Shotwell moving along
    A new feature that was included is a contrast slider in the enhancement tool, moving on with integrating patches hanging around on Bugzilla for quite some time.
  • GObject and SVG
    GSVG is a project to provide a GObject API, using Vala. It has almost all, with some complementary, interfaces from W3C SVG 1.1 specification. GSVG is LGPL library. It will use GXml as XML engine. SVG 1.1 DOM interfaces relays on W3C DOM, then using GXml is a natural choice. SVG is XML and its DOM interfaces, requires to use Object’s properties and be able to add child DOM Elements; then, we need a new set of classes.
  • LibreOffice 5.1.6 Office Suite Released for Enterprise Deployments with 68 Fixes
    Today, October 27, 2016, we've been informed by The Document Foundation about the general availability of the sixth maintenance update to the LibreOffice 5.1 open-source and cross-platform office suite. You're reading that right, LibreOffice 5.1 got a new update not the current stable LibreOffice 5.2 branch, as The Document Foundation is known to maintain at least to versions of its popular office suite, one that is very well tested and can be used for enterprise deployments and another one that offers the latest technologies.
