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!

openSUSE uses RPM for its own packaging needs, with macros on their own on top. However, the distributions using RPMs are just a couple compared to the vast Linux ecosystem. How are other distributions handling packaging? Are they using bash scripts, functions, or even declarative languages? This talk will give a rundown of the different approaches that have been more successful in building a distribution on top, such as Gentoo ebuilds, Void Linux packages, and even some more niche packaging spec files.

With the types of products and projects that we regularly work on many of us don't get alot of exposure to new fancy technology, this talk aims to give a quick introduction to one of these topics, web assembly. As some background, For the last year i've been helping to port Little Piggy Tracker (LGPT) a clone of the LSDJ audio software for Game Boy to various handheld devices. At the same time I saw a conference talk that was an introduction to web assembly, this prompted me to ask the ever dangerous question "how hard can it be?" It turns out the answer to that question was not that hard so this talk will go through a brief overview of webassembly followed by the process I went through to port my code along with some of the other challenges i've had porting LGPT to other devices.

Ever wonder what goes on behind the scenes to keep your favorite open-source projects (relatively) secure? Spoiler alert: it's not magic (mostly)! This talk is a peek into the world of a security engineer who spends their days auditing code, hunting down vulnerabilities, and trying to make the open-source world a little less "Oops!" and a little more "Awesome!". We'll dive into: - What actually goes into a software audit. (Think less "spreadsheets," more "WTF is that?") - The thrill (and occasional horror) of vulnerability research. - Why this matters to you, even if you don't write code for a living. (Hint: it's about more than just avoiding the next big breach.) - How we, as a community, can all contribute to making open source safer – because, let's face it, we're all in this together. So, if you've ever been curious about the security side of open source, or just want to hear some war stories from the front lines, come join me! Let's talk about how we can make the open-source ecosystem more secure, one audit at a time. For you, for me, for everyone!

Distributed compute at scale is a bit complex back home in Mauritius - cloud service providers are literally an ocean away, and local policies have a history of hindering technological progress. To "bring the cloud home", so to speak, a small team of tech enthusiasts decided to build a Kubernetes (K3s) cluster distributed across the country, in a bid to drive down costs while boosting resilience and availability. This session goes over the challenges of setting up such a geographically distributed cluster on baremetal hardware, including fighting latency, connection issues, dynamic IPs, and distributed storage, all while keeping costs minimal. While not entirely technical in nature, this presentation will go over some of the very unique challenges of living on an island in Africa with regards to The Cloud and digital infrastructure in general.

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.

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.

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!

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.

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.

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

Scham durchdringt alle Lebensbereiche. Was passiert, wenn wir unsere Scham offenlegen? Wie reagieren wir, wenn wir uns selbst mit unserer Scham konfrontieren? Ist Scham eigentlich immer sozial? Das Kollektiv Rhymth berührt uns mit fragmenthaften Texten, vielen kleinen, nicht selten aufwühlenden, intimen„Alltagserfahrungen“ und detaillierten Beobachtungen. Durch das Offenlegen des Individuellen hoffen wir, das Kollektive besser zu verstehen. Language: DE + EN Translation: YES Recording: YES Shame permeates all areas of life. What happens when we reveal our shame? How do we react when we are confronted with our own shame? Is shame always social?

„Haare ab, Haare hoch, steil, ein Gebirge aus Haar, Haare wie Messer, die aus dem Kopf stechen.“ Eine jugendliche Punkerin spricht am Ende der DDR über ihr Leben und ihre Erfahrungen. Ihr älteres erwachsenes Ich kommentiert und reflektiert aus der Zukunft. Es geht um Kunst und Liebe, um Anarchie, um das Rumhängen mit Freunden, um das Baden in der Kiesgrube und darum, dass sie nicht Frau sein will, sondern Punk, aber immer wieder Frau sein muss. Durch die Ich-Figur gehen diverse politische Diskurse hindurch und  kommen spielerisch zum Ausdruck. Noisiger Live-Sound unterstreicht die Wortspiele.  Language: DE Translation: YES Recording: YES “Hair off, hair up, steep, a mountain of hair, hair like knives sticking out of the head. "A young punk talks about her life and experiences at the end of the GDR. Her older adult self recalls the past from the future. It's about art and love, anarchy, hanging out with friends, swimming in the gravel pit. It’s not wanting to be a woman but a punk, and always being put back into a woman-shaped box. Various political discourses are coursing through the first-person narrator in a playful way. Noisy live sound underscores the juicy words.

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!

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.

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.
