Hardware Shenanigans

(originally titled “On Dead Trees”)

There’s features that you know are really important to some of our users but you frankly don’t really care for them much yourself. Printing is one such example. Recently, I actually had to print lots of paperwork, so I had a reason to fix some of my more pressing issues with our Print Manager.

The biggest regression from the Plasma 4 days, when we moved from individual System Tray popups to a unified square view, was that Print Manager had to give up its two pane layout that showed the print queue directly in the popup. In order to view and cancel print jobs, you now had to select the printer and open its print queue window, and close it again after you’re done.

Little Wayland Things

While I do have a Qt git build on my machine that I use for development, I usually only test individual applications and functionality but hardly ever run my full Plasma session on it. This means that for day-to-day use I typically only get to enjoy new Qt features once they have actually been released.

Do you want to save your changes or discard them?” ontop of a KWrite editor window that is darkened because the prompt is modal — Proper modal dialogs under Wayland (note the darkened editor window) thanks to XDG Dialog and the new Qt 6.8

Plasma Browser Integration 2.0

I’m pleased to announce the immediate availability of Plasma Browser Integration version 2.0 on the Chrome Web Store and Microsoft Edge Add-ons page. This release updates the extension to Manifest Version 3 which will be required by Chrome soon. The major version bump reflects the amount of work it has taken to achieve this port.

Plasma Browser Integration bridges the gap between your browser and the Plasma desktop. It lets you share links, find browser tabs and visited websites in KRunner, monitor download progress in the notification center, and control music and video playback anytime from within Plasma, or even from your phone using KDE Connect!

Getting ready for Akademy

Next week Akademy, KDE’s annual community conference, will take place in Würzburg, Germany. There are a few features that I actually began during various conferences throughout the years to address real-world problems. I decided to have look at some of them again that would be most useful for people travelling to Akademy from abroad or who will be giving a presentation there.

Fresh Breeze Dialog Icons

The Breeze icons used in message boxes always felt a little odd with a status icon placed inside some kind of speech bubble, effectively an icon within an icon. Three months ago they got replaced by more simplistic ones that I felt didn’t fit very well either. Therefore I put my Inkscape skills to the test and created a new set of Breeze-style dialog icons.

Three message boxes staggered: red octagon with a cross “This is an error”, orange triangle with exclamation point “Be careful, please”, blue circle with an I “Everything is alright”

A Fresh Perspective on Things

Can you believe it’s already been almost half a year since Plasma 6.0 came out? Time really flies! The other day I went through some of my 50+ open merge requests on KDE’s GitLab and took another stab at them. Some are four years old at this point but it definitely helped to let them sit for a while and finish them with a fresh new perspective and clear mind.

Plasma Browser Integration 1.9.1

I’m pleased to announce the immediate availability of Plasma Browser Integration version 1.9.1 on the Firefox Web Store. This is the Firefox release of version 1.9 that was released way back in November 2023. We’re not sure how it got stuck in Add-on review and that we didn’t realize this but whatever the reason, it’s out now! This is a maintenance release shipping a couple of important changes as well as the usual translation updates. The extension is of course fully supported under Plasma 6!

Contributing is more than just code

When thinking about how to contribute to KDE, many people probably still think that you have to write actual code. While it’s true that C++ and QML is at the heart of our applications, it’s just one puzzle piece of many that make up a successful product. Besides donating money to KDE or developers like me individually, there’s much more you can do to support us: promo work, drawing icons, brainstorming ideas, writing documentation, triaging bug reports or writing new ones, or in this case sending the relevant piece of hardware to a developer. Every single contribution counts!

A key ingredient to KDE’s cross-platform story is Solid, our device integration framework. It lets applications enumerate devices, such as hard drive partitions, USB thumb drives, but also batteries and peripherals, in a platform-independent way. When it comes to hardware, sometimes emulating its behavior is tough and even a virtual machine might not behave exactly the same as the real thing. Here’s the story of how the donation of a portable DVD drive let me unlock a massive performance boost.

Plasma 5: The Early Years

With KDE’s 6th Mega Release finally out the door, let’s reflect on the outgoing Plasma 5 that has served us well over the years. Can you believe it has been almost ten years since Plasma 5.0 was released? Join me on a trip down memory lane and let me tell you how it all began. This coincidentally continues pretty much where my previous retrospective blog post concluded.

KDE Release Party in Nürnberg

Last night SUSE invited to their new Nürnberg offices at the Franken Campus in the city’s south for a KDE MegaRelease 6 release party. There were around 25 people from KDE, SUSE, and owncloud, with a good portion of non-contributors meeting some of the people behind their favorite desktop environment and suite of applications in-person for the first time.
