Porting Software To Qt5, KDE Frameworks 5

Filed under
Development
KDE

For those interested in bringing their software (or helping in port open-source software) to KDE Frameworks 5 and Qt5, Aleix Pol has written a semi-detailed overview covering the general steps involved.

Aleix covers various documentation resources for KF5/Qt5, getting started, CMake changes, QML changes with Qt Quick, and other considerations.

Freshen up your KDE’s Plasma desktop using Evolvere icons

Filed under
KDE

Icon sets for Linux, especially for the KDE’s Plasma desktop, have usually been scarce, with not so many themes being complete nor good looking. Oxygen icon set looks and feels outdated, and Faenza and Kfaenza mods from different people over the past years gradually morphed into frankenstein projects. There have been attempts at completing icon sets that would give your desktop some crispness and freshness, but many of them, despite being well designed and though out, lack many commonly used app icons, or monochrome tray icons, or, well, take your pick, you probably went through the same experience as I did.

Artikulate port to GStreamer-1.x is ready to merge

Filed under
KDE

As an pronunciation trainer, Artikulate does not only need sound output, but also sound input. For sound output the (Linux) world is kind of simple and it only costs some lines of code to integrate Phonon or a similar framework into your application. For sound input it is trickier, especially if you do not want to work with a C-style API (when coding a C++/Qt application, C-style API feels very strange). The solution to this problem is QtGStreamer, which provides Qt-style C++ bindings for GStreamer, and hence access to the currently best multimedia framework.

  • Sponsors required for KDE code sprint in Randa

    KDE is organizing a "coding sprint" in Randa, Switzerland. KDE Developer Sprints are focused gatherings of KDE developers to work on a specific part of KDE. Sprints are an opportunity to plan, design, and hack (think 20% socialization and 80% perspiration). Though sprints are supported by KDE e.V. financially and organizationally, we are having more enthusiastic people than funds allotted to us by KDE e.V. We need your support in helping us to fill this gap.

  • Starving Developers

    Phonon, a pillar of our multimedia solutions, was revived in Randa. Kdenlive, our video editor, became 302% more awesome in Randa. The KDE Frameworks 5 movement seeking to make our awesome libraries more useful to all the world started in Randa. Amarok 2 was planned in Randa. Approximately a godzillion bugs were fixed in Randa.

  • Geogebra file support in Kig ( GSoC Report )

    KIG currently has filters for various formats ( Cabri, Dr-Geo, KGeo, KSeg ). I have been working on implementing the Geogebra-filter for KIG. Here’s some introduction about the Geogebra-filter that we are trying to implement :

  • First Report

    As the title (Lyrics Support improvements) of my Google Summer of code project suggests, I am improving the way lyrics are fetched and displayed in Amarok. Personally, I like to follow the lyrics of the song that is playing; so I added this is idea to the Idea Page for GSoC 2014. And now here I am, working on it. I goal of my project is to highlight the particular line from the entire lyrics text that is being played.

  • Last week in Krita — week 23 & 24

    In the last two weeks, besides the coding work on the git repositories, Boudewijn has made available a hefty number of testing builds for the windows community. This builds brings up the latest novelties and features developed in the master branch. Note, however, not all feature sets are finished and it is not recommended for production use.

  • after convergence

    Two years later I gave a presentation summarizing these thoughts at Akademy in Dublin. A desktop layer that was stackable like a normal window ("dashboard" in today's jargon), scripted components instead of compiled applets, dataengines, network services, dynamically loading different layouts for different user activities, using threads to keep the UI fluid, easy animation systems, configure/manipulate-in-place, a window manager that did more than just put title bars around things, etc. It was finally time to get to turning scribbles in notebooks into code. (I was still maintaining various parts of KDE's 3.x desktop at the time, in particular kicker, as well as working on a variety of other bits of KDE software. This, along with a semi-crazy travel schedule kept me busy with productive things while these ideas were crystallizing.)

  • QML module versions and automatic imports
  • Five Musings on Frameworks Quality

    KDE Frameworks 5 will be released in 2 weeks from now. This fifth revision of what is currently known as the “KDE Development Platform” (or, technically “kdelibs”) is the result of 3 years of effort to modularize the individual libraries (and “bits and pieces”) we shipped as kdelibs and kde-runtime modules as part of KDE SC 4.x. KDE Frameworks contains about 60 individual modules, libraries, plugins, toolchain, and scripting (QtQuick, for example) extensions.

It’s always nice to come across Kubuntu being used in the wild. Recently I was pointed to a refurbished laptop shop in Ireland who are selling HP laptops running Kubuntu 14.04LTS. €140 for a laptop? You’d pay as much for just the Windows licence in most other shops.

KWin is no more

Filed under
KDE

Now that I have your attention: the binary of KWin/5 just got renamed from “kwin” to “kwin_x11″. For you as a user nothing changes, the startup is adjusted to start kwin_x11 instead of kwin. Nothing else changed. The D-Bus interface is still org.kde.KWin, the config file is still “kwinrc”, etc. etc. Only if you start KWin manually remember to run “kwin_x11 –replace &” instead of “kwin –replace &”.

How To Encrypt DNS Traffic In Linux Using DNSCrypt

​Dnscrypt is a protocol that is used to improve DNS security by authenticating communications between a DNS client and a DNS resolver. DNSCrypt prevents DNS spoofing. It uses cryptographic signatures to verify that responses originate from the chosen DNS resolver and haven’t been tampered with. DNSCrypt is available for multi-platforms including Windows, MacOS, Unix, Android, iOS, Linux and even routers. Read
