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. We will leave you and us with some answers and many open questions.

In this talk, we’ll explore how Supervision streamlines common computer vision tasks, from loading datasets to annotating and analyzing images or videos. We’ll also discuss its lightweight nature, making it an ideal choice for running AI-powered vision applications on resource-constrained devices. Through practical demonstrations, attendees will learn how to set up and optimize Supervision for real-world IoT applications, including smart surveillance, automated counting, and industrial monitoring.

Whether you're a developer, researcher, or IoT enthusiast, this session will show how you can leverage Supervision to bring efficient computer vision solutions to edge devices.

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 **profitability** in their overall business while maintaining **control over their data.**

In this session, we will explore the **Edge Ecosystem Analytics** and its transformative potential in **GenAI Applications** through seamless orchestration via **openSUSE Leap** and **Rancher-managed Kubernetes**. This approach helps overcome challenges in adopting and deploying cutting-edge GenAI applications securely and efficiently at the edge.

Key Topics:

- Overview of **Large Language Models (LLMs)**

- Scope for **Edge Computing** in AI revolution

- Benefits over privacy concerns by **localization of LLMs**

- Real-world Application Showcase by leveraging **GenAI for Edge Ecosystem Analytics**

- Integration of Retrieval-Augmented Generation (**RAG**) Pipeline into **Rancher & K3s**

- Challenges while deploying **GenAI applications at the Edge**

This short talk will showcase a real-world GenAI-based application, highlighting the utilization of the **RAG pipeline** as well as a **data modeling pipeline** to continually improve analytic outputs and its seamless integration with **Rancher and K3s**. Attendees will learn about **Rancher and K3s** in managing Kubernetes deployments for GenAI applications, LLM optimization techniques such as **RAG**, overview of **Fine Tuning** and **AI Agents**.

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 during this talk, and I hope it triggers a discussion around how we can further optimize and support mirrors for smaller economies. If we get things right, it can be a template for other countries that still do not feature on [mirrors.opensuse.org](https://mirrors.opensuse.org).

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 build a custom controller that monitors for unauthorized changes, implements smart rollback decisions, and provides real-time notifications. Learn how to leverage ArgoCD's API to implement advanced reconciliation patterns, track drift metrics, and create audit trails of all remediation actions. Perfect for teams dealing with dynamic environments where maintaining configuration consistency is crucial.

This session advances the GitOps ecosystem by:

- Introducing new patterns for extending ArgoCD's core functionality

- Contributing an open-source drift detection framework

- Demonstrating advanced use cases for Resource Hooks

- Providing solutions for common enterprise compliance challenges

- Showing how to build sophisticated automation around ArgoCD

- Sharing reusable patterns for custom health checks

- Adding intelligence to standard GitOps workflows

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.

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? The collective Rhymth touches us with fragmentary texts, many small, often disturbing intimate “everyday experiences” and detailed observations. By revealing the individual detail, we hope to better understand the big picture.

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!

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 feedback that improved kiwi in the process, and the takeaways for encouraging broader community adoption of good tools, regardless of who they're from.
