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...

In this talk, we’ll explore how Supervision streamlines common computer vision tasks, from loading datasets to annotating and analyzing images or videos.

The exponentially growing **AI/ML** and **LLMs** advancements bring concerns about privacy, as there is a risk of data exposure to online LLMs service providers. Setting up **LLMs in-house** requires a **high computational cost** which is a major obstacle for businesses across various sectors such as Retail, Healthcare, Finance, etc. These industries seek to leverage the power of LLMs to drive **p...

At oSC23, I [presented](https://www.youtube.com/watch?v=abNBhLug2Ls) the challenges that we, a small community of openSUSE users, faced back home when building our first mirror in Mauritius. Two years later, I'm sharing updates on how we're expanding further and adding a second mirror in Mauritius to host more mirror content for the local community. We still face challenges, which I will share dur...

Let's discover how to extend ArgoCD's capabilities by building a sophisticated drift detection and auto-remediation system. We'll demonstrate how to combine ArgoCD's Resource Hooks, Custom Health Checks, and the ApplicationSet controller to create an intelligent system that not only detects configuration drift but automatically resolves it based on defined policies. Through live coding, we'll buil...

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 hof...

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 a...

We'll showcase the next big thing for authentication @ SUSE, the current landscape and the challenges we're facing.

Many of you know that the [kiwi](https://osinside.github.io/kiwi/) appliance image build tool is used to produce most of openSUSE's images. But did you know that other distributions have recently adopted it too, particularly our friends in the Fedora and CentOS projects? This presentation discusses the story of how this came to be, the methodology of encouraging growth and development, the feedbac...

Es gibt sie, die guten Lösungen für (Klima-)Gerechtigkeit und echte Nachhaltigkeit, auch wenn einige rechte, alte Männer gerade alles tun, um mit aller Gewalt den Deckel drauf zu halten. Maja Göpel, Nachhaltigkeits- und Transformationsforscherin, ist eine, die ihr alle kennen solltet! Autorin zahlreicher Bücher, Forscherin und Beraterin. Immer ist sie mit der Frage beschäftigt: Wie können wir das...

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 a...

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 s...

Unsere langjährige Weggefährtin Greta teilt mit uns ihr fundiertes Wissen zu Menopause, hormonellen Hintergründen, emotionalen Symptomen und dem Einfluss persönlicher Lebensmuster. Sie nährt uns mit ihrem Wissensschatz, QiGong-Körperübungen und neuen, stärkenden Ideen zu einer Lebensphase, über die wir entweder gar nicht oder negativ sprechen – lasst uns das gemeinsam ändern! Wechseljahre, ein The...

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 soft...

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 tes...

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 go...

The current process of openSUSE membership application can be cumbersome and overall approval deem lengthy or inconsistent. This is due to way applications are made, some times information is lacking, there are back-and-forths, before membership officials can finalise an application. The current state of membership management has its limitations and it is not friendly, either for the members, the...

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 r...

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, c...

In this session, a brief explanation about what Uyuni is and what it can achieve will be shared as an introduction for newbies or as a knowledge reminder for the part of the audience already knowing the product. This part of the session is mainly a summary of last year's session. Secondly, we will try to summarize the changes that have happened within the last year in Uyuni, in the period of time...

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...
