You uses Debian? - Cern - Debian in outerspace Why are a distribution like Debian with "a normal release cycle" is still relevant for KDE? Can KDE Linux replace Debian? What it is about to package KDE software on Debian? Who is the current Qt/KDE Maintainer team. Why does Debian ship that old versions? Why can't we just ship master branch? Speak about what were/are the current challenges regarding packaging KDE software on Debian: - loosely coupled Palsma - kde pim (ABI) - transitions from 4->5, 5->6 - lts support - QML dependecy tracking - bring patches to Debian stable - bring current version to Debian stable https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de

The Linux printing ecosystem is currently undergoing one of its biggest architectural transitions in decades. Since the [CUPS 2.2.x][1] series, printing has increasingly moved toward [IPP-native and driverless][2] workflows, allowing applications to print directly to discovered IPP print destinations without requiring manually created print queues, PPD files, or vendor-specific driver filters. With the upcoming transition to [CUPS 3.x][3], legacy printer drivers and classic PPD-based queue creation will be removed entirely from CUPS itself. Non-driverless printers will instead require Printer Applications that expose printers through modern IPP interfaces. These changes significantly affect desktop printing infrastructure and require desktop environments to adapt to more dynamic, asynchronous, and network-oriented workflows. This talk explores the ongoing modernization work in KDE Print Manager to prepare for these changes. It covers the migration away from older synchronous request handling, improvements to UI responsiveness and request lifecycle management, and the architectural challenges involved in modernizing mature desktop infrastructure software while maintaining compatibility with existing workflows. The session will also provide an overview of how KDE Print Manager interacts with CUPS and the broader Linux printing stack, discuss the implications of the CUPS 3.x transition for KDE and Linux desktops, and highlight future directions for modern desktop printing infrastructure. Whether you are interested in KDE internals, Linux desktop architecture, or the future of printing on Linux systems, this talk offers insight into the engineering challenges and design decisions involved in preparing KDE Print Manager for the next generation of Linux printing. Tarun Srivastava has started the work voluntarily in the end of 2024, continued it as [Google Summer of Code 2025 project for OpenPrinting][4] (his [final report][5]) and is currently working on its completion in the [Google Summer of Code 2026][6]. His main mentor is Mike Noe, responsible for the [printing support in KDE][7], and additional mentors are Till Kamppeter, co-founder and lead of [OpenPrinting][8], and Nico Fella.

A talk in three parts, building towards a vision for a sovereign desktop in 2026 (and a look back). 1. **Loved**. In 2003, together with Eva Brucherseifer, Jan's company relevantive ran the first large-scale usability study of the Linux desktop on behalf of decision-makers considering migration. KDE 3.1 on SuSE was tested by 60 office workers with no prior Linux experience; 87% enjoyed working with it, 80% estimated they could reach professional competence within a week. The Linux desktop wasn't a usability disaster — but realising its potential required deliberate configuration, honest naming, and treating migration as a human-resources problem, not a technical one. The findings shaped a decade of OpenUsability work inside KDE. They are, awkwardly, almost entirely still applicable. We'll look at what stuck, what didn't, and why "lovable" — not merely "usable" — is the bar today, and why getting it right cuts the cost and risk of every migration discussion that follows. 2. **AI-native**. A desktop that loves you back has to know you. Personal AI has crossed the threshold where the desktop itself can be compiled per user, per device, per moment, from a small portable model of the user — what we are sketching as Kadai: an encrypted, vendor-agnostic personal kernel from which Plasma assembles each Activity. Plasma is uniquely well-fit for this — Activities, Plasmoids, the existing scripting surface — but a handful of upstream changes (declarative reconciliation, per-widget capabilities, richer Activity metadata) would turn KDE into the first shell that treats AI as infrastructure rather than as a chat box bolted to the side. 3. **Sovereign**. Once a user owns their model and their tools, the same question returns at institutional scale. EU institutions, member countries, and a long tail of organisations are openly asking what a credible, non-colonialising desktop stack looks like. No project carries this alone — a sovereign desktop is an ecosystem question. KDE is uniquely positioned as the shell, the integration layer, the experience; but filesharing belongs with Nextcloud, the browser with Firefox, the office suite with .... The last third of the talk is about what KDE's partnership surface could look like — outward, to industry and public administration, and sideways, to the allied open-source projects that already do the rest of the work better than anyone could redo it. Who owns that surface, where it lives, what KDE e.V. would need, what not to build. Sovereignty, from this angle, is just lovability and AI-ownership scaled up to the organisation: the user not owned by a vendor, the institution not owned by a foreign supplier — and the stack not owned by anyone, because the right partners hold the right pieces. This talk is an invitation — from peple with a long arc inside this community — to take a serious swing at the question the 2003 study posed and never quite resolved: what would it take for KDE to be the desktop people actively choose, not just the one some of us settle for? Attendees will leave with: a concrete proposal (KaDAi) to react to or tear apart, a clear set of asks the project could direct at Plasma maintainers, and the framing for a sovereignty conversation that KDE is uniquely positioned to lead.

In September 2025, a few of us Open Source nerds heard that the Bavarian government wanted to "sneakily" "invest" another billion Euro in Microsoft Cloud, Teams and 365 – without a tender, and before the year ends (Base contract) I talked to friends, and we created an open letter. Soon we were like ten initiators. We found support among many Bavarian Open Source companies and NGOs, only weeks later > 160 companies and institutions had been signing the letter. When larger German NGOs like the Gesellschaft für Informatik (Society for Informatics) and the Bund der Steuerzahler (Tax Payers' Association joined, the Bavarian Government could not stay silent any more. Leading up of today, two secretaries and the minister president have engaged in a public blame game. At first they were angry about the unwanted, additional publicity - and publicly said so. The goal of sneakily accomplishing the deal until end of 2025 failed and it is still not finalized. But now - four weeks before an election, secretaries of state for digital and finance are fighting publicly, accusing each other of "fake news" and are saying silly things. On camera - and in parliament. "OSS is too expensive" or "We needed something federated, decentralized and secure, thus we had to go for MS 365" and similar. It's fun. What we can learn from this? PR for OSS works, timing is helpful, topics are important and claims like "ONE BILLION!!" are valuable. No one knew Trump, Greenland and Davos would come to help us, but they did and made it hard for the conservative Bavarian government to keep doing what they had always been. And we were a bunch of people that stuck it out. And it's so important that we the OSS community learn how to play against the lobbys. We need to apply the "divide and conquer" strategy against the real enemies, not internally. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de

StyleKit (formerly known under the working title "Unified Style") is a new QML module shipped with Qt 6.11 under the "Qt.labs.StyleKit" namespace. StyleKit is a declarative styling system for Qt Quick Controls _and_ Widgets, built on top of Qt Quick Templates. It lets you define a complete visual style for all your controls from a single Style document, including support for themes, state-based styling, and transitions. StyleKit handles the underlying template implementation automatically, letting you focus purely on visual aspects such as colors, dimensions, borders, and shadows. A key strength of StyleKit is its hierarchical property system: set a property once on a base type like abstractButton, and it automatically applies to all button-like controls. Override it where needed for specific controls or states. Changes to your style are instantly reflected across all controls, ensuring consistency while still allowing fine-grained customization. This talk will introduce the module, demonstrate how it works, and outline future plans. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de

In 2026, the Sovereign Tech Fund commissioned work to bring KDE software closer to readiness for large enterprises and public institutions. As part of this work, KDE PIM infrastructure had to be improved. In this talk, we will cover the bug fixing and improvements we did around Akonadi resources and their protocol libraries. This will help all the applications using Akonadi to be at the forefront in term of protocol updates. To get there, we also setup an end-to-end tests suite using Python. We will thus do a detour on how we structured those tests for better test data management and reduced flakiness. It will also show the bugs you can catch this way but not with unit tests. If your life is stored in an IMAP and a DAV server, if you'd like things to be easier to configure, or if you'd like a better Flatpak experience for KDE PIM applications, then join us and rejoice! We'll tell you what you can expect to see in the next release. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de

By examining its past, its present restoration, and its potential future, this presentation contextualizes Oxygen, the flagship theme of the KDE 4 era, within the broader questions it raises for KDE as a project. We argue two things about Oxygen: that it carries genuine historical and artistic value, and that KDE's continued stewardship of the theme reflects something important and positive about our community. Namely that KDE Plasma is a user's desktop, one that is willing to prioritize user choice over narrow cost-benefit development logic. In recognition of both Oxygen’s value and in line with the values of KDE, Oxygen has been undergoing an active restoration effort. We present the state of that work: what has been accomplished, what obstacles were encountered, and what dilemmas arise when preserving a theme of this kind. Here we also take the very positive user feedback received as a signal that there is clear demand for designs rooted in the very principles Oxygen is rooted in. The future certainly does not involve redesigning the Oxygen that was, but it does carry the potential of its evolution into the Oxygen that will be, new modern Oxygen's, built on the same principles, of pushing the boundaries of what we do in the design space in OSS. This work also opens a larger question about what KDE wants to offer in terms of theming infrastructure and available themes. Our position is that preserving the original Oxygen is worthwhile in its own right, and that working on its evolution can be beneficial for bettering the new theming infrastructure, as fostering the next generation of OSS designers. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de

Lars Wienand berichtet aus seiner Arbeit zu Desinformationskampagnen aus Russland. Es geht um die Kampagnen Storm-1516, Matryoshka und Doppelgänger. Von "Doppelgänger" mit seinen nachgebauten Nachrichtenseiten war Wienand Entdecker und entlarvte Akteure dahinter. Er berichtete als erster Journalist über das jüngste Leak bei Planern und Machern der Kampagnen in einer Moskauer Firma. Zugleich taucht er immer wieder selbst in absurden Beiträgen auf: Zuhörer lernen Günther Wienand kennen, den älteren und ermordeten Bruder von Wienand, von dem dieser selbst nichts wusste. Aber dann meldete Moskau, dass Merz Verdächtiger beim Mord an Günther ist und Wienand deshalb verärgert ist über Merz.

Wir werten Abstimmungsdaten zum systematischen Einriss der Brandmauer im Europaparlament aus und lernen daraus für die Zukunft. Mit den Landtagswahlen in Sachsen-Anhalt scheint eine Regierung unter Beteiligung von Rechtsradikalen so wahrscheinlich wie noch nie. Potenzielle direkte Zusammenarbeit mit der AfD wird dabei sowohl von Konservativen ausgeschlossen, als auch gesellschaftlich kritisch begleitet. Das **Europäische Parlament** erhält dagegen regelmäßig weniger Aufmerksamkeit - Abseits des Rampenlichts stimmen hier **Rechtsradikale und Konservative** seit 2024 regelmäßig gemeinsam ab. Zentrale Politikfelder wie die Migrationspolitik werden so von Rechtsaußen-Parteien geprägt - ganz ohne formale Zusammenarbeit mit diesen Akteuren. Basierend auf **Datenanalysen** von namentlichen Abstimmungen im Europaparlament arbeiten wir heraus, wie Konservative und Rechtsradikale systematisch **gemeinsame Mehrheiten** gebildet haben - und es dabei geschafft haben, dass der ganz große Aufschrei ausblieb. Wir sprechen über die **Normalisierung** von Tabubrüchen, wann gemeinsames Abstimmen problematisch ist und wie man das methodisch erfassen kann. Wir untersuchen verschiedene Definitionen davon, was eine **Brandmauer** ist und wo wie viel davon noch steht. Während wir die Normalisierungsprozesse auf europäischer Ebene nachvollziehen, versuchen wir **diskursive Gegenstrategien** für zukünftige Debatten zu entwerfen und auf Kontexte außerhalb des Europaparlaments zu übertragen. _Wie sprechen wir über antidemokratische Politik - nach der Brandmauer?_ Der Vortrag richtet sich an alle, die ein Interesse an parlamentarischen Prozessen und kein Interesse an Rechten haben.

Bertha von Suttner proposed a system designed not merely to end wars, but to prevent them. How is her concept applicable today? More than a century ago, Bertha von Suttner warned that industrialization would make future wars increasingly destructive. In her 1906 Nobel lecture, she proposed three foundations for lasting peace: international arbitration, an international court, and a Peace Union whose members would collectively resist any aggressor. Peace, in this model, is not simply the absence of war. It is an international order designed to make aggression predictably unsuccessful. Elements of this idea later appeared in the League of Nations and the United Nations. Yet Russia’s invasion of Ukraine demonstrates that international law cannot reliably prevent war without credible enforcement. Does peace require the capacity to defeat an aggressor? Can armed forces deter war without militarizing civil society? When does appeasement prevent escalation, and when does it encourage further aggression? This talk revisits von Suttner’s Peace Union as an unfinished architecture of collective security—and asks what would be required to make it work today.

TiX is an decentralized, deterministic, user owned, globally designed workflow engine from the future TiX.im is a fully decentralized, composable, deterministic, workflow engine DAG for interactive and automated workflows in highly isolated containers. A nix based framework allows the user to build very complex, multi step workflows spanning any agent, harness, script, build step, ... that can be parametrized in an easy way. Workflows can transition between states and are globally reachable using the iroh network. A unique combination of multiple decentralized networks, the tix.build system, is the first of its kind that can ensure that each software artifact published in the network has succeeded rigorous supply chain analysis by multiple parties as well as a deterministic build process that was succeeded by multiple parties. By splitting the signature key into multiple parts, in which one part is locked inside the maintainers hardware dongle and the other part is distributed among hundreds of nodes (mpc-2pc), any node in the system can be compromised but a malicious release can be prevented. Since AI supported software attacks, mutating worms, unicode attack vectors (glass worm), etc became so sophisticated and fast, a complete new set of attack vectors arose that require novel solutions. This talk will be an architectural design overview with an live demo of this experimental infrastructure project still built in stealth - for a reason.

Wir präsentieren die besten Fundstücke aus den 6.5 GB, die wir aus Datenschutzanfragen von Firmen über uns bekommen haben. Das Internet vergisst nie. Das haben wir alle schon mal gehört. Aber was bedeutet das eigentlich? In diesem Vortrag zeigen wir das Chaos, die größten Aha-Momente und die bizarrsten Details, die wir erlebt haben, als wir unser europäisches Recht auf die eigene digitale Vergangenheit eingefordert haben. Wir haben hunderte Unternehmen nach unseren personenbezogenen Daten befragt: Online-Shops, soziale Netzwerke, Werbefirmen, Krankenkassen, Dating-Plattformen und viele mehr. Wir bekamen alles – von handgeschwärzten PDFs bis hin zu Gigabytes an CSV- und JSON-Daten – und versuchten, daraus unser eigenes Online- und Offline-Leben zu rekonstruieren. Um mit den Datenmengen umzugehen, ließen wir die KI Ordnung ins Chaos bringen. Nur um plötzlich zu realisieren, dass sich daraus eine nahezu komplette Biografie unseres Lebens basteln ließ. In diesem Talk packen wir all die Datensätze aus, die wir bekommen haben: kleine Online-Shops, mittelgroße Tech-Firmen und die Silicon-Valley-Giganten. Haben wir wirklich noch nie jemanden beim Online-Dating geghostet? Können wir nachvollziehen, wo wir vor zehn Jahren im Urlaub waren? Und wollen wir überhaupt wissen, was unser Suchverlauf über uns verrät? Als Live-Demo lassen wir während des Talks einen Agenten auf unsere eigenen Daten los - denn was kann da schon schiefgehen? Schauen wir gemeinsam, wie viele peinliche Details Firmen jetzt schon über uns alle wissen!

Arrest, torture or persecution: how the Russian occupation is changing the lives of LGBTQ+ people In this talk, we discuss how Russia’s anti‑LGBTQ+ policy has become a component of the occupation regime. Drawing on human‑rights research, documented witness statements, and my own experience working with the LGBTQ+ community in the Kherson region, I report on forms of persecution, survival strategies, and the documentation of war crimes. We kindly ask for your understanding: this talk can unfortunately only be held in Ukrainian. A live English translation will be provided on stage.

In this presentation I would like to discuss the work we have done over the last few years towards getting closer to our users and how it culminated in my work embracing BuildStream as a solution for our builds. We will cover why it is a good idea, why it's an area that is important to put a lot of care on and how we will do to make sure that it remains a good idea and, most importantly, which possibilities BuildStream enables once everything is in place.

The desktop interface has remained fundamentally unchanged for over two decades, relying on legacy paradigms that haven't scaled to meet new modern needs. Industry leaders like Apple and Microsoft are too deeply entrenched in their established ecosystems to risk radical shifts. While the Linux community has shown some appetite for experimentation, much of it has nibbled at the edges such as focusing on tweaking window management. This talk reflects my lifetime experience as a UX designer at Apple and Google and how the deepest innovations happen at the most mundane level: richer input, better data flows, and breaking out of our 2d windowing prisons. Ironically, the open source nature of Linux and specifically KDE provides a unique opportunity to break free from these legacy constraints.

... Or How the Sovereign Tech Fund Invested in KDE In 2026, the Sovereign Tech Fund commissioned work to bring KDE software closer to readiness for large enterprises and public institutions. Members of KDE e.V., enioka Haute Couture, and Techpaladin Software joined forces to prepare the proposal which led to this investment. Join us to get a peek behind the curtain of such an endeavor. We'll explain how we got there and our (not so) secret recipe for success. In this talk, we'll cover the scope of the project and explain how the conversation with the Sovereign Tech Agency unfolded. This will also include insights on how we structured and estimated such a large project. Can we expect further momentum for KDE products' adoption in the enterprise and public institutions? Is this the next step in KDE's quest for world domination with freedom and choice? You be the judge.

In 2006, I prepared my first Kdenlive release. Twenty years and 151 releases later, where are we ? Is Kdenlive still relevant ? Will it finally get GPU support ? How is the community doing ? And more importantly, are we still having fun ? I will try to answer these questions, and give you a better overview of our plans.
