These past two days I attended the Qt World Summit 2025

It happened in Munich in the SHOWPALAST MÜNCHEN. The venue is HUGE, we had around 800 attendees (unofficial sources, don't trust the number too much) and it felt it could hold more. One slightly unfortunate thing is that it was a bit cold (temperatures in Munich these two days were well below the average for May) and quite some parts of the venue are outdoors, but you can't control the weather, so not much to "fix" here.

The venue is somewhat strangely focused on horses, but that's nothing more than an interesting quirk.

Qt World Summit is an event for the Qt developers around the world and the talks range from showcases of Qt in different products, to technical talks about how to improve performance along others less Qt centric talks about how to collaborate with other developers or about "modern C++".

As KDE we participated in the event with a stand trying to explain people what we do (David Redondo and Nicolas Fella were more in the stand than me, kudos to them)

For following years we may need to re-think a bit better our story for this event since I feel that "we do a Linux desktop and Free Software applications using Qt" is not really what Qt developers really care about, we maybe should focus more on "You can learn Qt in KDE, join us!" and "We have lots Free [Software] Qt libraries you can use!".

Talks for the videos will be published "soon" (or so I've been told). When that happens the ones I recommend you to watch are "Navigating Code Collaboration" by LAURA SAVINO, "QML Bindings in Qt6" by ULF HERMANN and "C++ as a 21st Century Language" by BJARNE STROUSTRUP, but the agenda was packed with talks so make sure to check the videos since probably your tastes and mine don't 100% align.

All in all it was a great event, it is good to see that Qt is doing well since we use it for the base of almost everything we do in KDE. Thanks to The Qt Company and the rest of the sponsors for organizing it.

It has been quite a long time since I attended any KDE sprint, last sprint for me was Plasma Sprint in Valencia, Spain before pandemic and personal life got in a way. Last month I had chance to attend Plasma Sprint 2025 in Graz, Austria. This was good opportunity for me to meet some of long time contributors to Plasma Mobile like Devin Lin and Luis, as well as other Plasma contributors to discuss some of technical details about my upcoming power management work.

I'll soon start my second project supported by NLnet and the European Commission. For the first one I spent way too much time figuring out if I need to pay taxes on the funding I receive. At least value added tax does not apply! However, German tax law is not clear about income tax from what I can tell, and even writing a petition to the federal ministry of finance to clear things up still leaves me with most of the uncertainty. In any case, I did not need to pay income tax on the funding the first time around. Who knows if it will stay this way?

If you might find yourself in a similar situation one day, I strongly recommend to save yourself many hours of headaches and read my German blog post about this. Here it is: https://wordsmith.social/felixernst/wie-man-keine-steuern-auf-europaisch-geforderte-softwareprojekte-bezahlt

I don't want to translate German legalese into English.

If you can't read German, that's a bit of a cliffhanger now, isn't it? Well, sorry about that. However, you might want to cherish the fact that you probably don't need to deal with German tax law! Also consider that it is probably better for your sanity anyway if you don't spend your time learning about taxation in other countries. It's not a good conversation starter, trust me.

Introduction

Another year, another successful Season Of KDE for 10 contributors!

This article has been co-written with the input from all contributors.

Kdenlive

Kdenlive brings you all you need to edit and put together your own movies. We had 1 project for KDE's full-featured video editor:

• Swastik Patel animated transition previews in Kdenlive by extending the TransitionListWidget with a dual-view system (tree/icon) and creating a custom TransitionIconDelegate for rendering GIF previews. The core functionality is powered by a Python script that leverages MLT to generate standardized preview GIFs by applying transitions between colored clips or custom images. The implementation integrates with Kdenlive's existing asset management system, utilizing QStandardPaths for preview storage and QMovie for GIF playback. The UI updates are triggered through signal connections when frames change, providing real-time preview updates in the transitions panel. This enhancement allows users to visually evaluate transitions before applying them to their projects. All the code changes are in this merge request.

  

KDE Eco

There are 4 new projects related to the KDE Eco project. This helps make KDE software more efficient and environmentally friendly, as well as more accessible at the same time:

• Anish Tak worked on a new tool, Win2KDE-Chooser project to help users migrate from Windows to Linux by recommending KDE-based distributions. A questionnaire was designed to understand the user's needs, mapping their responses to distribution parameters like ease of installation, hardware support, and community backing. Further, a recommendation engine was implemented in the backend to rank distributions according to user preferences and hardware specifications. Overall, a functional MVP was created that suggests suitable KDE-based Linux distributions based on users' needs and hardware capabilities.

  

• Oreoluwa Oluwasina built a new GUI for the emulation tool KdeGuiTest formerly known as KdeEcoTest with features that allows users to easily create and run a standard usage scenario script. Button commands that records the actions made by a user have been implemented and they display real time in the action buffer widget. The scripts can be modified in the final script widget to finalise each script before saving it in a text file. A combo box has been implemented to toggle to the run script interface where users can select and run final scripts. Additionally, a "Platform supported" error was encountered and fixed by installing a custom pynput package and other packages like Rust.

  

• Roopa Dharshini worked on writing technical documentation for the KEcoLab project. After a detailed exploration on the KEcoLab project, an outline was crafted. This mentorship program taught valuable practical experience in team collaboration and in thinking of approaching various possible solutions to a problem.

  

• Shubhanshu Gupta worked on rewriting and restructuring the documentation for KEcoLab to make the project more accessible to newcomers. This includes explaining usage scenario scripts-core to KEcoLab's process-and how they simulate real-world software usage to measure energy consumption. The structure of its repository was mapped out, for a clearer understanding of the project. The experience deepened Shubhanshu appreciation for technical documentation and collaborative development of FOSS communities.

  

Mankala Engine

The Mankala Engine is one project started during last year Google Summer of Code to introduce a new game to KDE. During this year SoK, we had a lot of projects to improve this game.

Two new variants were added:

• Rishav Ray Chaudhury implemented the Kalah game for the Mankala Engine. A greedy move selection algorithm was also added and a script for generating a benchmark report for the available games and algorithms.

  

• Srisharan V S integrated the traditional game Pallanguli into the Mankala Engine. After researching regional rule variations and the core game logic was implemented in C++. A package of the engine for Fedora has been created, fixing the reported bugs and ensuring everything worked smoothly. Later, I organized a FOSS meetup at my college to showcase KDE apps and help students try out Linux. Finally, I completed the documentation and polished the codebase for future contributions.

  

• Shubham Shinde worked on enhancing the Mankala Engine by exploring and implementing new gameplay algorithms like MCTS and Q-learning, comparing them with existing ones like Minimax and MTDF. While MCTS didn't perform well, Q-learning showed better results after optimization. Review and improvement suggestions were also provided on the Pallanguli variant implementation.

  

• Ashutosh Singh worked on creating a GUI for mankala Game. This development was done using Kirigami and qml for creating and designing the GUI. The GUI is functional but it is still a work in progress with several bugs and missing elements which need to be implemented. The current state of the game can be see below.

  

• Nidhish Chauhan have implemented a feature in the engine supporting Player versus Player (PvP) mode, with real-time XMPP-based communication for PvP. The project includes a terminal-based user interface, move tracking, and game state management, along with a man page for documentation.

  

One of the next steps for the game is to follow the KDE review process and becomes an official KDE application!

New Mentors

The projects were guided by several people new to welcoming contributors to KDE through SoK. Thanks go to Kieryn Darkwater, João Gouveia, Aakarsh MJ, Pradyot Ranjan and Snehit Sah for giving new contributors an introduction to free and open source software.

Closing

We would like to congratulate all participants and look forward to their future journey with KDE!

This month has been amongst the most intense of my FOSS journey I'd had in a while. We had both the Plasma sprint and the LinuxAppSummit (LAS).

You can follow what was done in the sprint at the many blog posts by our teammates. Thank you all!

When it comes to LAS, you can look at most videos here. However, you'll be missing out on the experience of joining it. Consider joining next year!

All in all, it gave me a nice feeling of realisation that we are on the right track at large. Plasma is getting lots of love by our devs, ensuring a continued stream of improvements to our UX. From a Plasma standpoint, we are slowly exploring the possibility of having add-ons with Flatpak. I find this an exciting development that can bring Plasma extensions to a next level, that wouldn't be feasible without the work from many of the folks at LAS.

And all that to say that we are all fine, and healthy. Either Plasma or LAS, both are nice communities full of nice people pushing our ecosystem together towards new horizons that I'm sure we'll all be happy to explore.

Happy hacking!
