The Space-Time Continuum of KDE's Activities

Filed under
KDE

This is not about KDE e.V.'s new time travel program. This is about Plasma and its concept of Activities. They have been a topic of hot debates. Some people love them, some don't care. Björn called for finding a new metaphor which better fits the mental model of the user, so that Plasma's activities can appeal to a larger group of people. Here are my thoughts.

Development
KDE

We are happy to announce the release of Qt Creator 3.4 RC1 today.

I already described many of the new features in the beta blog post. Since then, we fixed many bugs, including a whole lot of debugger integration issues, and generally polished Qt Creator for release. You find the more complete change log at code.qt.io.

Enhancing user experience through the Compositor

Filed under
KDE

Some time ago Ken introduced the conecept of dynamic window decorations (DWD) and during the last Plasma sprint there was already some work on experimenting with an implementation. DWD are extremely promising to enhance the user experience by morphing the application and window manager scope together.

The basic concept of DWD is to get content of the application inside the scope of the window manager. But what works one way works also the other way: we can enhance the user experience by providing additional information relevant for the window inside the window decoration.

Plasma 5 with KDE Telepathy 0.9

Filed under
KDE

While every effort in KDE Telepathy went to the Qt5/KDE Frameworks 5 porting and KAccounts migration, there are still distros/users that have KDE Telepathy 0.9 (the kde4 one) running in Plasma 5 session. All the applications of KDE Telepathy work just fine, the only problem are the Plasma applets, those are totally incompatible.

So for those cases I've created a small Plasma 5 applet which works with KDE Telepathy 0.9. It can bring your accounts online or offline or open the contact list and accounts settings, just as you're used to and the only dependency is TelepathyQt5. However because of changes in Plasma 5 stuff, it's not perfect.

  • PyKDE Future: Seeking a New Maintainer

    For anyone who has been paying any attention of PyKDE5 over the last year or so, it is no secret that development and maintenance has been at a standstill. I've been very busy with a family and small children, and that eats time like you wouldn't believe. (Unit number 2 is almost 6 months now, healthy and happy I can report.) But another important factor is that my interests have shifted towards web related technologies over the last few years.

  • KDE 5_15.03 for Slackware-current

    qt-kde-620x350Here’s the latest and greatest of KDE’s software collection (Frameworks, Plasma, Applications). SInce my last ‘ktown’ release, all of KDE’s sources have been renewed, and today I am making public a package set for KDE 5 aka Plasma 5 with version 5_15.03: my March ’15 release.

The 9 best distros for KDE’s Plasma desktop

Filed under
KDE

While it's possible to install 'KDE' software and Plasma desktop on most Linux based distributions, I have picked the distros which offer Plasma as their default desktop environment. These 'KDE-based' distros offer a better Plasma experience compared to those where you can 'also' install KDE.

At some point in time I have used each of these distros as my primary OS except for Mageia and Open Mandriva, which I tried but never used due to uncertainty around their future.

11 Activities for KDE Plasma

Filed under
KDE

Why should you use KDE Activities? The best way to answer that question is to give some concrete examples of what you can do with them.

Activities are virtual desktops. They share a common panel and menu, but each has its own layout and selection of items on the desktop. In addition, each has its own virtual workspaces and wallpaper.

To build an Activity, select from the Desktop Toolkit Activities > Create Activities. Give the Activity an icon and a name, and select a layout from the Desktop Settings. In the KDE 4 series, these layouts include Search and Launch, a netbook desktop; Newspaper, a grid for arranging wizards, and several others whose purpose is obscure to many readers. The new Plasma 5.2 appears to eliminate all except Desktop and Folder, but that may be because it is just starting to be used, and layouts for the new release have yet to be written.

FATHOM releases Crystallon

  • FATHOM releases Crystallon, an open-source software for lattice-based design
    Lattice structures are integral to 3D printed designs, and Aaron Porterfield, an industrial designer at additive manufacturing service bureau FATHOM, has developed Crystallon, an open source project for shaping them into structures.
  • FATHOM Introduces Open Source Software Project for Generating 3D Lattice Structures
    California-based FATHOM, which expanded its on-site managed services and announced important partnerships with Stratasys and Desktop Metal last year, is introducing a fascinating new open source project called Crystallon, which uses Rhino and Grasshopper3D to create lattice structures. FATHOM industrial designer Aaron Porterfield, also an Instructables member, developed the project as an alternative to designing lattices with commercially available software. He joined the company’s design and engineering team three years ago, and is often a featured speaker for its Design for Additive Manufacturing (DfAM) Training Program – and as the project developer, who better to explain the Crystallon project?

Kernel and Graphics: Machine Learning, Mesa, Wayland/Mir, AMDGPU

  • AI-Powered / Machine Learning Linux Performance Tuning Is Now A Thing
    A year and a half ago I wrote about a start-up working on dynamically-tuned, self-optimizing Linux servers. That company is now known as Concertio and they just launched their "AI powered" toolkit for IT administrators and performance engineers to optimize their server performance. Concertio Optimizer Studio is their product making use of machine learning that aims to optimize Linux systems with Intel CPUs for peak performance by scoping out the impact of hundreds of different tunables for trying to deliver an optimal configuration package for that workload on that hardware.
  • Pengutronix Gets Open-Source 3D Working On MX8M/GC7000 Hardware
    We've known that Pengutronix developers had been working on i.MX8M / GC7000 graphics support within their Etnaviv open-source driver stack from initial patches posted in January. Those patches back at the start of the year were for the DRM kernel driver, but it turns out they have already got basic 3D acceleration working.
  • SDL Now Disables Mir By Default In Favor Of Wayland Compatibility
    With Mir focusing on Wayland compatibility now, toolkits and other software making direct use of Mir's APIs can begin making use of any existing Wayland back-end instead. GTK4 drops the Mir back-end since the same can be achieved with the Wayland compatibility and now SDL is now making a similar move.
  • Mesa 18.1 Receives OpenGL 3.1 With ARB_compatibility For Gallium3D Drivers
    Going back to last October, Marek of AMD's open-source driver team has been working on ARB_compatibility support for Mesa with a focus on RadeonSI/Gallium3D. Today that work was finally merged. The ARB_compatibility support allows use of deprecated/removed features of OpenGL by newer versions of the specification. ARB_compatibility is particularly useful for OpenGL workstation users where there are many applications notorious for relying upon compatibility contexts / deprecated GL functionality. But ARB_compatibility is also used by a handful of Linux games too.
  • AMDGPU In Linux 4.17 Exposes WattMan Features, GPU Voltage/Power Via Hwmon
    AMD's Alex Deucher today sent in the first pull request to DRM-Next of AMDGPU (and Radeon) DRM driver feature material that will in turn be merged with the Linux 4.17 kernel down the road. There's some fun features for AMDGPU users coming with this next kernel! First up, Linux is finally getting some WattMan-like functionality after it's been available via the Windows Radeon Software driver since 2016. WattMan allows for more fine-tuning of GPU clocks, voltages, and more for trying to maximize the power efficiency. See the aforelinked article for details but currently without any GUI panel for tweaking all of the driver tunables, this WattMan-like support needs to be toggled from the command-line.
