In the South, food and music go hand in hand. They define much of what we think of as Southern culture, and they say a lot about our past, our present, and our future. Each week, Sid Evans, Editor in Chief of Southern Living, sits down with musicians, chefs, and other Southern icons to hear the stories of how they grew up, what inspires them, and why they feel connected to the region. Through honest conversations, Sid explores childhood memories, the family meals they still think about, and the intersection of food and music in their lives. Always surprising, always engaging, Biscuits & Jam is a celebration of the South—and the people who are moving it forward every day. New episodes every Tuesday.

Auf dem Hackover 24 hatten wir uns das Jahr 2023 im Kontext des globalen Klimawandels angeschaut. Der Vortrag endete mir der Aussicht, dass wir im Jahr 2024 das häufig medial beschriebene 1,5 Grad Ziel zu überschreiten dürften. Das haben wir auch erfolgreich geschafft. Der Talk stellt eine aktualisierte Version des Talks vom letztem Jahr dar. Wir fassen nochmal ein paar Punkte des globalen Klimaberichts des IPCC zusammen und ordnen dann die Messewerte des Jahres 2024 ein. Einige Teile sind daher für wiederkehrende Besuchende vielleicht vom letzten Jahr noch bekannt. Als neue Dimension (weil es Stand Juni 2025 in den Medien auftaucht) gucken wir zusätzlich auf das Grundwasser, da der Sommer für uns ja gerade erst beginnt.

In diesem Vortrag schauen wir uns an, wie der Game Boy Advance Handheld grundlegend funktioniert und wie mit gezielten Softwaretests neue Erkenntnisse gewonnen und die Kompatibilität von Emulatoren verbessert werden kann. Nintendo veröffentlichte den Game Boy Advance im Jahr 2001. Seitdem verkaufte sich der Handheld über 80 Millionen Mal und ist damit eine der meistverkauften Konsolen. Kurioserweise kam der erste Emulator für das System bereits vor dem offiziellen Release heraus und konnte bereits erste Demos ausführen. Seitdem hat sich das Verständnis der Hardware signifikant verbessert und damit auch die Detailgetreue von Emulatoren. In diesem Vortrag schauen wir uns an, wie die Hardware grundlegend aufgebaut ist und wie mithilfe gezielter Softwaretests neue Erkenntnisse gewonnen werden können. Dabei lege ich einen besonderen Fokus auf die 2D GPU / Pixel Processing Unit.

Gelangt die sexpositive Ära an ihr Ende? Ein Gespräch über das erotische Potenzial des derzeit vorherrschenden kollektiven Turn-Offs. Ein Gespenst geht um im Feminismus – das Gespenst der Unlust, des Überdrusses, der Enttäuschung über unerfüllte Glücksversprechen. Sexpositivität erzeugt Druck, die Arbeit an fuckability scheint wichtiger als der Genuss von Intimität. Beate Absalon lädt uns ein, neugierig zu sein. Auf welchen Sex haben wir keinen Bock mehr – und wie sähe ein anderer, utopischerer Sex aus? Sluts and Prudes vereinigt euch! Referenziertes Video bei 6:30 https://www.youtube.com/watch?v=ploHR84-9UA A specter is haunting feminism – the specter of disinterest, weariness, disappointment over unfulfilled promises of happiness.

After _certain_ events caused massive upheaval in the virtualisation landscape, many companies using that technology have found themselves dropped into the deep end, with skyrocketing infrastructure costs and furious upper management. Promising a stark opposite to high costs, limited flexibility, and vendor lock-in, Harvester takes the stage. Harvester is an open source hyperconverged infrastructure solution built by SUSE, and provides a complete package for everything compute, networking, and storage. This presentation will take a peek under the hood of Harvester and how it leverages existing open source solutions to provide a scalable and resilient virtualisation platform - in particular Longhorn, which is the distributed block storage engine powering storage in Harvester and Kubernetes clusters around the world. Attendees will leave this talk motivated to replace their existing production infrastructure with Harvester, powered by the flexibility and high availability of Longhorn. So, whether you are looking at bringing the cloud back to your server room, or reducing costs with existing infrastructure (while ensuring prod isn't at risk), then this talk will get you started!

In this session, I will show you how to use Agama, the new next-generation installer, to perform effortless advanced unattended installations on openSUSE Linux. Whether you are installing just a few desktops or a fleet of servers, Agama makes the process fast, smooth, and hassle-free. This modern installer is poised to transform not only openSUSE installations but also deployments across other Linux distributions. While older tools like AutoYAST work well, they are not always easy or user-friendly for unattended advanced Linux installations. Agama solves this with a simple yet modern web interface that makes unattended installations easy and possible for everyone. I will demonstrate how to use Agama’s latest features, including how to set up and initiate remote connections using IP addressing or Multicast DNS for a fully unattended OpenSUSE installation. You will also learn about Agama’s main key features such as its simple JSON-based configuration language to create auto installation profiles, an HTTP API for integrating with third-party application tools, and how to import your existing AutoYAST profiles. Join this session to see how Agama can save you a lot of time and effort by making your OpenSUSE Linux deployments easier and more powerful than ever before.

How does openSUSE look from the outside? In this talk, two SUSE expats share how their Geeko hearts started to ache when they were no longer part of the inner circle. Where are openSUSE's strengths, and how are they shining? Where does it desperately need to improve to maintain relevance? There is so much excellence across so many disciplines to be presented to communities outside SUSE's roof. Is openSUSE targeted being an in-house project, or is it ready to engage more broadly with the open source world? Expect some war stories from the days after, and some highly subjective advice.

No one wants to be responsible for breaking the build. But what can you do as a developer to avoid being the bad guy? How can project leads enable their teams to reduce the occurrence of broken builds? In talking within our own teams, we discovered that many developers weren’t running sufficient integration and End to End tests in their local environments because it’s too difficult to set up and administer test environments in an efficient way. That’s why we decided to rethink our entire local testing process in hopes of cutting down on the headaches, heartaches, and valuable time wasted. Enter Kuttl. Connecting Kuttl to CI builds has empowered our developers to easily configure a development environment locally that accurately matches the final test environment — without needing to become an expert CI admin themselves. These days, we hear, “Who broke the build?” far less often — and you can too! Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de…

Open-source software has transformed the software industry, resulting in lower costs, greater security, and much greater flexibility for software developers and end users alike. The transparency provided by open-source software has improved security dramatically. Companies cannot hide back-doors in open-source software. Open solutions allow widespread review and testing, resulting in improved software quality and security. While there are a few open-source hardware projects, most notably RISC-V, most hardware remains proprietary and closed-source. Engineers developing new products often use chips that are black-boxes. This is particularly problematic when developing solutions using hardware secure elements, small security chips used in IoT devices, crypto hardware wallets, mobile devices, industrial control systems, and other small devices. Developers have no visibility into the implementation of these devices, and cannot validate their security. In this presentation we will cover: Challenges with closed source hardware secure elements: Our experience with closed source secure elements (and the problems we found) Benefits of open source/open architecture hardware secure elements: Transparency, trust, and auditability Rapid response to vulnerabilities Community collaboration and innovation Compliance & certification Get your devkit at the workshop or order here and start playing! :) https://145324096.hs-sites-eu1.com/samples-order-form Documentation and tools: https://github.com/tropicsquare Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de…

How do you scale quality in a fast-moving open source project like Uyuni? In this talk, I’ll walk you through our journey adopting TestOps practices to bring automation, visibility, and resilience into our quality engineering process. We’ll explore how infrastructure automation with Terraform and Salt laid the foundation for consistent, on-demand testing environments. From there, we introduced test observability using Prometheus and Grafana to analyze historical trends and gain visibility into test behavior over time. A key part of our process includes tracking flaky tests and known issues through a custom system that connects our internal QE workflows directly with test reports. To accelerate feedback loops, we implemented smart test selection in Pull Requests, targeting only the affected components with relevant end-to-end tests. We also integrated synthetic monitoring of key product metrics into our daily pipelines, ensuring continuous insight into overall health. Thanks to designing our own DevContainers, we improved engineer's experience on their IDEs. We are also working on providing public AWS-based test reports reinforcing transparency. Our journey is a story of small, iterative changes that helped us align quality with development at scale.

### Introduction: The Need for Secure and Reliable Booting In the ever-evolving landscape of Linux distributions, security and boot reliability have become paramount concerns. Traditionally, the boot process relied on separate kernel and initrd components, leading to potential vulnerabilities and complexities. This presentation delves into the journey of integrating a more robust and secure boot mechanism by leveraging the Unified Kernel Image (UKI). ### Static and Signed Initrd: Establishing a Foundation for Integrity We will begin by outlining the critical need for a static and signed initrd within modern Linux systems. The dynamic nature of traditional initrd generation can introduce vulnerabilities, as the contents are often generated at boot time, potentially exposing the system to tampering. By moving towards a static initrd, we achieve a higher level of predictability and security. Signing this static initrd ensures its integrity, preventing unauthorized modifications and bolstering the system's overall protection. ### Building and Distributing Static Initrd in openSUSE A brief overview of the practical steps involved in building a static initrd will be provided. We will explore the methods employed to streamline this process and integrate it seamlessly into the openSUSE distribution. ### The Unified Kernel Image (UKI): Definition and Advantages The core focus of this presentation will be the Unified Kernel Image (UKI). We will define what a UKI is, explaining its structure and the benefits it offers. This approach significantly simplifies the boot process, enhancing security and reducing the attack surface. ### Building in openSUSE: Challenges and Solutions for Enhanced Reliability We will then showcase the specific work undertaken within the openSUSE distribution to build and integrate UKIs. This includes the process to build from the open build service, and the necessary tooling to manage them and the bootloader configuration. We will discuss the challenges encountered and the solutions implemented to ensure a smooth distribution from the OBS to UKI-based booting system. But also features like addons, snapshots or profiles. This integration allows for efficient distribution and management of UKIs, ensuring consistent and reliable boot environments across various openSUSE installations. ### Future Directions and Conclusion: Towards More Robust Boot Environments Finally, we will discuss the future direction of UKI implementation in openSUSE, including potential enhancements. This conference aims to provide a comprehensive overview of the UKI implementation in openSUSE, offering valuable insights for system administrators, developers, and security enthusiasts alike.

The Linux kernel scheduler is a critical component, profoundly impacting system performance and responsiveness. Traditionally, changing the scheduler has involved recompilation, rebooting, or complex kernel module management – a significant barrier for experimentation and fine-grained performance tuning. SchedKit dramatically simplifies this process, enabling users to dynamically switch between schedulers at runtime, without reboots or kernel modifications, opening up new possibilities in customizing kernel scheduling for the specific usecase. This talk introduces SchedKit, a new open-source project leveraging the power of eBPF and the sched_ext framework. SchedKit allows users to leverage custom Linux schedulers as standard OCI (Open Container Initiative) images. These scheduler containers are then launched and managed by the user's preferred container runtime (e.g., Docker, Podman, containerd). Through the magic of eBPF and sched_ext, SchedKit seamlessly attaches these containerized schedulers to the running kernel, changing the existing scheduling policy. Thanks to `schedctl` we can automatically download a new scheduler, run it, and have it attached to all the subsequent processes. ... and it's of course available on openSUSE!

Using configuration management like SALT or ansible for servers or more or less simple applications is standard practice in the industry. But, what if we talk about complex systems with special configurations and complex interactions? In the production industry we talk about "digital twins", which enables faster development and better integrations. For IT systems we talk now about a "digital blueprint" for our systems. Right now it's a vision we are evaluating - it should enable us to do "one-click-installations" of complex landscapes as well as generating a human readable description of the architecture. It hopefully shifts us from "define an architecture and implement something similar manually" or "sketch the architecture of an existing system" to a system synchronized with the architecture. A big part is the structured, templated description of the system and conventions or defaults how systems typically look like. We'll look at some already existing building blocks useful for implementing the vision, but we'll also sketch some missing parts or ideas to raise the full potential of our vision.

When using tools like RPM or Zypper for updating packages, there is a risk of incomplete updates or breaking the running system. To overcome these challenges, we have developed **container-snap**, a prototype plugin designed to deliver **atomic OS updates** that are fully applied or rolled back without compromising the system's state. **container-snap** leverages OCI images as the source for updates and integrates seamlessly with openSUSE’s [tukit](https://github.com/openSUSE/transactional-update) for transactional OS updates. By utilizing **Podman’s btrfs storage driver**, it creates bootable btrfs subvolumes directly from OCI images, effectively turning them into atomic OS snapshots. This allows you to build OS images using familiar tools like Docker or Buildah and deploy the container image on your host. This lightning talk covers the following topics: - The `container-snap` architecture and implementation details - Main development challenges and solutions - Lessons learned in bridging container tech and OS updates - A live demo showcasing atomic updates in action Join this session to learn more about how to boot from an OCI image without bricking your system!

When proprietary products are discontinued or bought up by competitors, your own (decision-making) freedom can quickly become precarious. A discontinued product forces you to migrate, incurs costs, and imposes unwelcome decisions. Not so with open source software: it offers me the freedom to develop the code further at any time, either on my own or with new partners, and to set up new support chains. The freedom not to have to migrate and the freedom not to have to work with an unpleasant service provider. Even drastic changes in product and business strategy can be avoided by taking matters into your own hands. At least that's the theory. But does it work in practice? This report is about a very recent case: about software that wasn't supposed to die, and a team that absolutely wanted to continue. It also shows where theory meets practice and the headwinds you have to face when you just go for it. But: a community has to do what a community has to do. And that can also mean: let's fork!

Uyuni offers two powerful APIs (XMLRPC and JSON) to integrate additional third-party applications. This talk demonstrates two integrations that allow users driving infrastructure automation: - an [Ansible collection](https://github.com/stdevel/ansible-collection-uyuni) that integrates Uyuni into Ansible and Event-driven Ansible. It allows controlling managed systems and enables users to continue using pre-existing Ansible environments such as AWX or Ansible Semaphore. Using this, fully automated patch management workflows are possible. - [a Terraform / OpenTofu provider MVP](https://github.com/svalabs/terraform-provider-uyuni) that can create resources within Uyuni I'd like to use this session to discuss how we can improve third-party integrations for Uyuni - e.g. by using the upcoming [OpenAPI](https://github.com/OAI/OpenAPI-Specification) / [Swagger](https://swagger.io/) functionality. This could speed-up development heavily. Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de…

SELinux is a Mandatory Access Control (MAC) system that enhances a system's security by enforcing policy-based access control rules. For a long time openSUSE and SUSE have relied heavily on AppArmor as default MAC system. With the decision to switch to SELinux as default MAC on SLE 16 and openSUSE Tumbleweed, there are multiple challenges that we have to overcome to integrate SELinux into those distributions. This session will give an overview on the current state of SELinux in openSUSE and SUSE, the plans for the future and what it means for users.

‘Public Money? Public Code!’ under this slogan thousands of individuals and hundreds of organisations come together and advocate for Free and Open Source Software in public institutions. Together with over 230 organisations the Free Software Foundation Europe (FSFE) is calling for public institutions to publish publicly financed software under a Free and Open Source Software license - If it is public money, it should be public code! The long-term goal of the initiative is to recognise and reduce the software dependency and vendor lock-in of public administration and to make public administrations digitally independent and sovereign. In this short talk, Bonnie Mehring introduces the "Public Money? Public code!" initiative by the FSFE and discusses how Free Software is the way to achieve digital sovereignty. Bonnie will discuss how public administrations can become digitally independent and benefit from Free Software.

Weltweit tobt ein Backlash zu Männerdominanz und rechter Ideologie. Woher kommt eigentlich toxische Männlichkeit? Schon in den 1970er Jahren analysierte Klaus Theweleit in Männerphantasien erstmalig die Verbindung von Männlichkeit, toxischer Sexualität und Faschismus. 45 Jahre später bringt Regisseurin Theresa Thomasberger das Werk auf die Bühne. Die drei Autorinnen Svenja Viola Bungarten, Ivana Sokola und Gerhild Steinbuch ergänzen das Stück um weibliche Perspektiven und zeigen, wie aktuelle Geschlechterbilder Gewalt, Ideologie und Identität prägen. Sonst auf der großen Theaterbühne, und jetzt exklusiv bei uns im Zelt! There is a global backlash toward male dominance and right-wing ideology right now. Where does toxic masculinity actually come from? Back in the 1970s, Klaus Theweleit analyzed the connection between masculinity, toxic sexuality, and fascism for the first time in his book Male Fantasies. Forty-five years later, director Theresa Thomasberger is bringing that work to the stage. Three authors complement the play with female perspectives and show how current gender images shape violence, ideology, and identity.

Wir wollen in unserem Projekt Menschen mit ALS unterstützen, indem wir Eye-Tracking als Kommunikationshilfe zugänglicher und günstiger machen, und das in gemeinnützig und Open-Source. In unserem Vortrag werden wir unser Projekt, die Erkrankung sowie Eye-Tracking als Technologie vorstellen. ALS und MS sind Krankheiten, die Betroffenen nach und nach die Kontrolle über ihren Körper nehmen. Am Ende bleibt meist nur die Augenbewegung übrig. Eye-Tracker sind Geräte, die die Augenbewegung aufzeichnen und als Eingabemethode nutzbar machen. Sie können somit als Kommunikationshilfe eingesetzt werden, zum Beispiel in Form einer Bildschirmtastatur, wo auf die Buchstaben geschaut wird, um zu tippen. Die Geräte sind keine Neuheit, sind aber als Reha-Geräte extrem überteuert, oder auf Gaming oder Marktforschung ausgelegt und somit für Betroffene nicht praktikabel. Wir möchten Eye-Tracker für Betroffene zugänglicher machen, indem wir passende Software und Hardware finden oder selbst entwickeln, Wissen vermitteln, oder vor Ort bei der Einrichtung helfen. Wir möchten, dass Menschen weniger bis gar kein Geld für eine Lösung ausgeben müssen.

In diesem Vortrag möchte ich _"Lichtung"_ vorstellen -- eine kleine Server/Client-Anwendung, die einen simplen Micorblogging-Service zur Verfügung stellt und somit eine Lichtung in den dichten Internet-Wald schlägt. Sie ist entworfen, um innerhalb eines IP-Netzwerks einen deterministischen Feed von Beiträgen und verschlüsselte Chatrooms zwischen je zwei Parteien bereitzustellen. Besonderen Fokus lege ich dabei auf die möglichen **Einsatzgebiete eines lokalen Sozialen Netzwerks**, die **technische Umsetzbarkeit** von persistenten Nutzer-Identitäten über nicht-föderierte Serverinstanzen hinweg und die **Probleme**, die sichere Verschlüsselung und echte Anonymität **für Moderatoren** mit sich bringen. --- Aus technischer Sicht werden hier diverse spannende Themen rund um asymmetrische Verschlüsselung/Signaturen, generative Kunst und Netzwerk-Routing verbunden: - Wie könnte ein Client aussehen, der mehrere Server gleichzeitig anspricht? - Wie stellt man eine pseudonyme Identiät über mehrere voneinander getrennte Netzwerke hinweg dar? - Und wie konstruiert man ein sicheres Netzwerk, in dem Server und Client sich gegenseitig niemals gänzlich vertrauen können? Umgesetzt wird das über asymmetrische Kryptografie, bei der immer zwei zusammengehörige Schlüssel generiert werden: Ein geheimer zum Signieren und ein öffentlicher zum Verifizieren. Genauso beim Verschlüsseln von Direktnachtichten: Mit dem öffentlichen Schlüssel können Nachrichten verschlüsselt werden, die nur mit dem dazugehörigen, privaten Schlüssel wieder geöffnet werden können. Auf diesem Prinzip lässt sich ein Kommunikationssystem aufziehen, das die klassischen Funktionen eines sozialen Netzwerkes implementiert, ohne dass der Server Anmeldedaten halten muss. Dabei spielen Identicons eine große Rolle, die aus den maschinenlesbaren Hashes des kryptographischen Unterbaus hübsche, für den Menschen leicht wiedererkennbare Muster generieren. Sie machen die hidden patterns des asymmetrischen Signieren und Verschlüsselns somit deutlich und greifbar! --- Aber auch die gesellschaftliche Perspektive muss bei einem solchen Projekt betrachtet werden: - Wie kann und muss ein digitaler, sozialer Raum moderiert werden? - Was sind die Implikationen von voller Anonymität im Internet und wie sicher darf eine Verschlüsselung überhaupt sein? - Welche Überlegungen muss ich treffen, bevor ich Inhalte von Nutzern auf meiner eigenen Seite bereitstelle? - Und wie können wir technische Lösungen schaffen, um Content-Moderation angenehmer zu gestalten? Moderne soziale Netzwerke, wie Instagram, Twitter oder TikTok sind für datenschutz-bewusste Menschen nahezu vollkommen unbenuzbar geworden. Erst kürzlich kündigte Meta an, **alle Nutzerdaten in state-of-the-art Machine-Learning-Systeme** zu füttern, um damit möglichst realistisches Nutzerverhalten zu simulieren. Das Fediverse mit Mastodon, Pixelfed, Feddit und vielen anderen Anwendungen setzt dagegen einen gesunden, dezentralen Kontrapunkt. Doch was _alle diese Netzwerke_ gemein haben ist, dass sie global und für jeden Menschen mit Internetzugang verfügbar sind. Dabei ist das Anwengungs-Modell, kreative oder lustige Text- und Bildbeiträge in einen zeitlich sortierten Feed zu posten, auch für **kleinere lokale Netzwerke** interessant! In Hackspaces oder Vereinsräumen könnte ein solcher Feed als **gemeinschaftliches Gästebuch** genutzt werden; auf Messen oder Festivals könnte **lokale Kommunikation und Vernetzung** vereinfacht werden, aber auch im privaten Heimnetz könnte eine solche Anwendung z.B. als **WG-Tagebuch** genutzt werden. Natürlich spricht auch nichts dagegen, eine Instanz ins **öffentliche Internet** zu stellen, und einen herkömmlichen Microblogging-Dienst zu betreiben. _"Lichtung"_ ist eine kleine Server/Client-Anwendung, die einen simplen Microblogging-Service zur Verfügung stellt. Sie ist entworfen, um innerhalb eines IP-Netzwerks einen deterministischen Feed von Beiträgen und verschlüsselte Chatrooms zwischen je zwei Parteien bereitzustellen. **Dabei sollen Nutzer-Identitäten über verschiedene Server-Instanzen und Netzwerke hinweg persistent sein und gleichzeitig eine hohe Datendiskretion gewahrt bleiben.** Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://cfp.gulas.ch/gpn23/talk/YE7PYL/…

Wenn man nur einen Hammer hat, sieht alles aus wie ein Nagel – so fühlt es sich manchmal an, wenn man die Begeisterung rund um „KI“ betrachtet. Gemeint ist dabei fast immer nur der Teilbereich generativer KI, die mit stochastischen Methoden plausible Ergebnisse produzieren soll. Links liegen bleibt dagegen „Good Old-Fashioned AI“, also regel- und logikbasierte Systeme, die mit semantischen Daten deterministische Schlüsse ziehen, ganz ohne Konfabulationen. Wer diesen Weg begeht, schafft gleichzeitig die Voraussetzungen für mehr Transparenz, Open Data und solide IT-Basisinfrastruktur. Prolog statt Chatbot, Daten statt Office-Dokumente – wir schlagen einen kleinen argumentativen Werkzeugkasten vor, wie wir als Community für solide, abgehangene IT-Lösungen auf dem Stand der Zeit bei Stadt, Land und Bund werben können anstatt für generativen KI-Budenzauber. Wer auf öffentlichen Bühnen „KI“ sagt, meint gerade viel zu häufig einfach nur das Teilgebiet der generativen Systeme, mit hohem Energieaufwand und einer Schleppnetzrunde durch die Inhalte des Web trainiert. Das User Interface und die Ergebnisse dieser Systeme wirken faszinierend, sie werden häufig anthropomorphisiert als seien sie Personen, und in der öffentlichen Debatte haben sie den Rang eingenommen, den vor sieben Jahren noch Blockchains haben – egal welches Problem, generative KI ist die Lösung. GenAI ist aber nur ein Teilgebiet von zwei historischen Strömungen im Forschungsfeld KI. Die andere Strömung, symbolische KI oder GOFAI („Good Old-Fashioned AI“) kommt vergleichsweise bescheiden daher: Daten und Wissensbestände sollen so aufbereitet werden, dass sie maschinell nach logischen Regeln ausgewertet werden können. Auch Prolog ist also „KI“, nur weiß das spätestens auf politischer Ebene kaum jemand mehr! Der einseitige Fokus auf generative Systeme hat aber absurde Seiteneffekte und Folgen vor allem für den Staat, der gerade genAI an allen möglichen passenden und vor allem unpassenden Stellen einzusetzen versucht. Denn ein heuristisches System ist zwar ausreichend, wenn es zum Beispiel darum geht, auf einem Bild einen Apfel zu erkennen. Für eine Verwaltung, die nach Regeln vorgehen und Gleiches stets gleich behandeln muss, sind regelmäßige stochastische Fehler aber nicht akzeptabel – ganz zu schweigen von den Seiteneffekten rund um Energieverbrauch und strategischen Abhängigkeiten. Wir möchten einen kleinen Werkzeugkasten vorschlagen, mit dem Du genAI-Projekte zerfragen und auf die strategischen Vorteile von Wissensgraphen und regelbasierten Systemen hinweisen kannst – und mit dem Du auch deine örtlichen GemeinderätInnen und Abgeordneten in die Lage bringen kannst, das zu tun. Denn vieles hängt einfach nur daran, Informationen nicht mehr in Office-Dokumenten (der „Käfighaltung für Daten“), sondern in Wissensgraphen zu speichern. Oder mit kleinen ETL-Skripten viel mehr Wiederverwendbarkeit und auch Open Data schaffen zu können als mit einem teuer beauftragten genAI-Projekt. Denn für viele vorgeschlagene Einsatzfelder gäbe es schon längst Lösungen, basierend auf abgehangener und bewährter Technologie – und gar nicht selten als Freie Software aus der digitalen Zivilgesellschaft entwickelt, die seither einfach ignoriert wurde.

KISS (Keep it Simple, Stupid!) ist ein Prinzip der Software- und Systemarchitektur, nach welchem Systeme möglichst einfach gehalten werden sollen. In diesem Talk möchte ich an dieses Prinzip erinnern, Positiv- und Negativbeispiele aufzeigen, und ein Plädoyer dafür halten, Systeme so einfach wie möglich zu gestalten. Diese Idee der Einfachheit hat auch als Architekturprinzip des Internets zu dessen schnellen Wachstum beigetragen bzw. dieses überhaupt erst ermöglicht. Leider wird dieser Ansatz in der heutigen Zeit der Frameworks, Microservices und KI oft vergessen. Deshalb möchte ich darauf eingehen, wo Komplexität entsteht und wie Einfachheit sowohl Kosten als auch Wartungsaufwand einsparen kann, aber auch diskutieren, wann das Einführen von mehr Komplexität sinnvoll sein kann.

Having looked at multiple implementations of DRAM initialization code for different platforms, both in binary and source form, I have started to see certain patterns occur. In this talk, we will focus on the binary form, since it is how that code is often distributed these days, and thus useful to gain an understanding of how modern DRAM controllers work and how they are integrated in contemporary platforms. We will walk through the process of finding data and data structures that are used in the code, and see how we can make sense of them, so that we can extract them as pure facts, or come up with simpler solutions for some of them when implementing our own initialization procedures. To assist us with different aspects of analysis, we will feature helpful tools and techniques for certain steps, and conclude with achievements made so far.

To ease the pain of testing container images, we’ve developed the `pytest_container` plugin for [pytest](https://pytest.org/). The plugin makes it possible to use pytest to perform tests on containers and software inside containers. You don’t have to take care of pulling images, building them, or picking ports on the host. You just describe your container setup and pass it to a test function. In return, the plugin gives you a connection to the container. Using the connection, you can verify the container’s state using the [testinfra](https://testinfra.readthedocs.io/) python framework. The plugin even cleans up after itself when you’re done. In short, `pytest_container` makes it possible to write tests in Python: no need to build your own framework from scratch or worry about the boring container plumbing tasks. Join this talk to see `pytest_container` in action and learn how it can make your life easier!

The Steam Deck has transformed mobile gaming — but in one crucial area, it still lags behind: security. Until now, no Steam Deck-focused Linux distribution has offered full disk encryption by default, leaving sensitive user data unprotected. In this talk, I present Yuga Linux, a distribution built on openSUSE technologies, tailored specifically for the Steam Deck with a strong focus on security, compatibility, and gaming performance. I will explain how Yuga Linux leverages openSUSE packages and the Open Build Service (OBS) to build a custom kernel and all essential components to fully support both SteamOS's gaming and desktop modes — while adding something no other Steam Deck distribution currently offers: secure, user-friendly encryption. You'll learn: - Why encryption matters for handheld gaming devices. - How I integrated tik, the installer from Aeon, to support TPM-backed full disk encryption. - How I built deckrypt, a custom tool that allows users to input passwords using the Steam Deck's gamepad when fallback manual unlocking is needed. - The challenges and key technical decisions behind building an openSUSE-based gaming distro for a new hardware category. The session will include a live demo of the boot process, unlocking the encrypted system, and running Steam Gamemode and Desktop Mode seamlessly on Yuga Linux. If you’re curious about gaming, Linux customization, TPM integration, or just want to see what the future of secure mobile gaming looks like, this talk is for you.

During the last year, I have spent several months on a project, that was sponsored by a grant from the NLnet NGI0 initiative. It is about an operating system, that only has packages that can be reproduced anywhere anytime bit-by-bit. I call it R-B-OS - the Reproducible-Builds-Operating-System. Last year when we had https://events.opensuse.org/conferences/oSC24/program/proposals/4378 , most of the work was still ahead. Now it is completed and I can tell how it went. I'll tell about the journey. And I'll tell about the result. RBOS has some unique properties: - The collection of sources are defined by a single hash, and so are the binaries produced from it. It is a 1->1 mapping. - When I change a toolchain package (e.g. gcc), I can let it rebuild and see exactly what changed in other places.

Werden wir alle bald arbeitslos oder entscheidet KI sogar über Abschiebungen oder Gerichtsprozesse? Wie viel Energie und Wasser wird dafür verbraucht? Und wie wird dadurch Macht auf die konzentriert, die diese Systeme kontrollieren? Language: DE Translation: YES Recording: YES How do AI and LLMs (Large Language Model) work, what can they do, and what can't they do? What ideologies of techbro-oligarchs like Elon Musk, Peter Thiel, Sam Altman, and others are behind them? Are we all going to be unemployed soon? Will AI decide on deportations and court cases? How much energy and water will this consume? And how will this concentrate power in the hands of those who control these systems?

Open source software is powering global innovation. In less developed regions, it's not just technology but a catalyst for closing the digital divide and fueling economic and social progress. This session explores how open source software goes beyond just coding as it creates real opportunities and positive change in the world’s least developed areas. For software developers in underserved regions, open source software offers free access to advanced technologies. This empowers them to build innovative IT solutions tailored to their communities’ unique needs. I will highlight the many benefits of adopting and customizing open source software in developing countries. These include lower IT costs for small businesses and organizations, and the ability to repair and reuse older computers and devices. By extending the life of hardware, open source software helps reduce electronic waste and environmental harm caused by discarded proprietary technology. Open source also boosts digital literacy and encourages collaboration and contribution within local tech communities, helping to bridge technology gaps. Using real examples from Africa, this session will show how open source projects are transforming education, healthcare, and other vital sectors, while helping to close the digital divide. Attendees will learn how their open source projects and contributions can create meaningful economic and social impact, especially in underserved and remote communities.

Recent global political events have up ended the global order. Coupled with the EOL of Windows 10, does Desktop Linux have a shot at the mass replacement of Windows in the corporate and government sectors? This wide ranging talk will cover the reasons why I think it does, and how we might achieve this goal. I believe it is easier than we think. **#Endof10 event** Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de…

Do you want to detect threats real-time and easily search logs to find relevant information? By default, incoming log messages are treated in log management apps as one long string. This is good enough if you just want to store logs. However, if you also want to act on log messages, you need more structured information. Syslog-ng and other applications also let you parse log messages. While parsing structured logs, like JSON, is easy, unstructured logs need a lot of work. This is where sequence can help you: if you have enough logs to analyze, it can automatically generate parser rules for syslog-ng and LogStash. Name-value pairs (sometimes also called “macros”) are probably one of the most useful parts of syslog-ng. Macros have been a core feature of syslog-ng since the beginning: incoming log messages were parsed by syslog-ng and various fields (priority, facility, date, program, PID and message) were stored into name-value pairs. You could use these to reformat log messages or use these values in file names. Without additional parsing, syslog-ng treats the message part of a log message as one long string. While this might be valid in some use cases, many log messages look like an almost complete English sentence with some variable parts in it. Just think about SSH login messages: they include the username, the source IP and port, and the login method embedded in a sentence. You might want to create an alert in syslog-ng for such messages (for example, if a root user logs in). However, if the whole message is a single string, you cannot do that. PatternDB can find important information in unstructured log messages, like the above-mentioned SSH login message, and create name-value pairs from the information it finds. PatternDB rules are easier to write than regular expressions and also need less resources to run. There are various parsers for structured log messages as well, like the CSV, JSON and XML parsers. You can also combine these and build really complex parsers. Sometimes, the syslog header might be missing from log messages, so you need to create a parser for the whole message. Message parsing and name-value pairs give you a lot more flexibility when it comes to filtering or templating log messages. For example, you can send an alert to Slack when someone logged in as a root user through SSH, or you can forward two important fields from an extremely long log message to save network bandwidth and disk space. You can use it to hide sensitive information and send only what is required to various destinations. Sequence-RTG allows you to automatically generate parser rules for syslog-ng and LogStash. Creating parser rules from scratch is a painful process. However, if you have enough log messages to analyze, sequence can do the heavy lifting for you. Of course, you might need to rename some of the name-value pairs, but that is a lot easier.
