Diving into Plasma’s 2015

Filed under
KDE

In terms of user demographic, we’re almost certain to see one thing happening with the new Plasma 5 UI, as distros start to ship it by default, this is what these new users are going to see. Not everybody in this group of users is interested in how cool the technology stack lines up, they just want to get their work done and certainly not feel impeded in their daily workflows. This is the target group which we’ve been focusing our work on in months since summer, since the release of Plasma 5.0. Wider group of users sounds pretty abstract, so let’s take some numbers: While Plasma 5 is run by a group of people already, the number of users who get it via Linux distributions is much larger than the group of early adopters. This means by the end of next year, Plasma 5 will be in the hands of millions of users, probably around 10 million, and increasing. (This is interpolated from an estimation of Plasma users in the tens of millions, with the technology adaption lifecycle taken as base.)

Display Managers In Plasma 5

Filed under
KDE

KDM was dropped from Plasma 5. KDM includes code from XDM dating back to 1988! It had served it's job well. However, we're now at a point where we need the backend to be Wayland ready and we want to use more modern QML in the front end. When you have to replace both the back and front ends, it's a sign to just start from scratch.

There was some work done 2 years ago into sharing code with LightDM. In the meantime a separate project was started, SDDM which is (yet another) display manager.

Although personally I was very happy with what we had with LightDM it definitely doesn't make sense to split resources, so we focussed everything on SDDM and I have been helping work on that transferring knowledge from my old project.

DWD – an FAQ for questions around the Web

Filed under
KDE

DWDs are not CSDs, and all theming and drawing is handled by the window manager and decoration. In addition, applications only export the structure of their widgets, they do not pre-draw or draw the widgets themselves. Applications would have little or no say in how their decorations look, just like traditional SSDs.

That being said, we don’t want DWDs to be absolutly rigid, we are looking at ‘safe’ ways applications can do basic branding on themselves in a reasonable manner, which decorations could potentially integrate without excessive effort. The main thing we are looking at is allowing applications to offer a colour pallet which decorations could use to tweak their appearance, but DWD ultimately would put the power in your hands and options would also be provided to disable unwanted hints and effects for more consistency. A primary sentiment with DWDs is that the user would be completely in control of all aspects DWDs would provide.

[Gwenview] Habemus Maintainer!

Filed under
KDE

14 years ago, I started creating an image viewer. Back then it felt like a good project to get started with graphical application development for my newly installed Linux system. Little did I know... In 14 years Gwenview went through one toolkit change (GTK+1.2 to Qt2/KDE2), got ported to Qt3/KDE3, moved from SourceForge CVS to KDE Extragear, got ported to Qt4/KDE4, became the default image viewer of KDE4 and finally got ported to Qt5/KF5.

[...]

You may be aware I spend most of my free time these days on some other project. I am not completely out of Qt and KDE development however: I have a number of small side projects, many of them Qt-based, to which I want to give a bit more visibility. Stay tuned for more announcements.

Filing bug reports for fun and profit

Filed under
KDE

Since jumping to an testing install of Plasma 5 in my upgraded Kubuntu, I've been filing bugs as I find things not working. It took me a few days to notice that redshift no longer worked, because I didn't always use it. But when I had my eyes dilated for my annual eye exam, I needed it! And it crashed.

I love filing bugs using ubuntu-bug from the commandline. I would love to see KDE build this capability as well, because the little application gathers useful information automatically, and uploads it to the bug tracker. Man ubuntu-bug says it reports problems to your distribution's bug tracking system, using Apport to collect a lot of local information about your system to help the developers to fix the problem and avoid unnecessary question/answer turnarounds. Dr. Konqui does this sometimes, but a little cli app would be nice as well.

Window and Desktop Switcher moved to Look’n’Feel Package

Filed under
KDE

Today we did an important change in how KWin will distribute its assets in the upcoming 5.2 release. When we started our thoughts about the Look’n’Feel Package and how we want to have meta themes for the complete Plasma workspace we also wanted to have this for the Window and Desktop switcher provided by KWin. So the structure of the Look’n’Feel Package already has all the pieces for including the Window and Desktop Switcher, but it was not used. Now we finally addressed this for the 5.2 release and moved the default switcher into the Look’n’Feel Package and KWin can locate the switchers from the Look’n’Feel Package.

    The Debian-based SolydXK Linux operating system has been updated today with patches for the Meltdown security vulnerability, as well as various other new features and improvements. To mitigate the Meltdown security exploit that allows a locally installed program to access the memory, including the kernel memory, and steal sensitive information like passwords and encryption keys, the SolydXK 201801 ISO images are now powered by the latest kernel release with patches against this vulnerability.
  • Chakra GNU/Linux Now Patched Against Meltdown & Spectre Security Vulnerabilities
    It's time for users of the Chakra GNU/Linux operating system to patch their systems against the Meltdown and Spectre security vulnerabilities as new kernel updates landed today in the repos. Publicly disclosed earlier this month, the Meltdown and Spectre security vulnerabilities are affecting us all, but OS vendors and OEMs are trying their best to mitigate them so that no user can be the victim of attacks where their sensitive data is at risk of getting in the hands of the wrong person.

GNOME Devs to Users: Desktop Icons Are Moving to GNOME Shell with GNOME 3.28

There appears to be a lot of fuss lately about the removal of an option from the GNOME desktop environment that allows users to display icons on their desktops. Long story short, last month, near the Christmas holidays, GNOME developer Carlos Soriano shared his plans on removing a so-called "the desktop" feature from the Nautilus file manager starting with the upcoming GNOME 3.28 release of the desktop environment, proposing its integration into the GNOME Shell component. The feature is there to handle application icons on the user's workspace, but it shouldn't have been implemented in Nautilus in the first place, according to the developer. So for the GNOME devs to be able to add new features to the Nautilus file manager, they need to remove its ability to handle desktop icons and place the code somewhere else. Read more

Yocto-on-i.MX6UL gateway serves up I2C and SPI on a DB9 port

Axiomtek’s compact “IFB125” DIN-rail IoT gateway runs Yocto Linux on an i.MX6 UL SoC with dual LANs, mini-PCIe expansion, extended temperature and vibration resistance, COM and USB ports, and a DB9 port that supports both SPI and I2C. Axiomtek has released a minor variation on its IFB122 IoT gateway. Like the IDB122, the new IFB125 runs Yocto Project code with Linux 3.14.52 on NXP’s 528MHz Cortex-A7 based i.MX6 UltraLight (UL) SoC. The headless gateway is designed for remote control and remote monitoring management applications such as unmanned control room, industrial automation, automatic parking lot, and traffic cabinets.
