As a first-year student who is currently starting my journey into open source, I understand the confusion and hesitation beginners face. In this talk, I will present a clear roadmap for getting started with open source, including understanding GitHub, finding beginner-friendly issues, and making the first contribution. I will also share common challenges beginners face and how to overcome them. This session is aimed at students who are at the very beginning of their journey and want a simple, practical starting point to enter the open-source ecosystem. Attendees will leave with a clear, actionable roadmap to start contributing to open source immediately.

In that time I have come across a number of its limitations especially if your goal is to write a config file that will work out of the box across a wide range of machines rather than creating tailor made configs for each machine. Beyond that writing a conky config that looks really good takes significant effort and often a lot of manually adjusting the location of elements. conky-bubbles aims to address the above issues using conky's lua integration and cairo to implement a layout engine, widgets, theming and hardware auto detection where possible. In this talk I will cover the long on and off process that it has taken to get to this point and the many unexpected challenges that I have had to overcome, from licensing issues to learning how to implement font rendering and chasing down memory leaks in the interface between C++ and Lua. I also spent significant time working with existing open source projects and will talk about integrating with and using resources from them to speed up development. I will then give a overview of how to setup and use and configure conky bubbles to meet your own needs. As well as running through a few examples.

It outlines the practical challenges encountered when bringing up graphics on new hardware—covering kernel driver readiness, firmware constraints, userspace integration, and Mesa driver maturity. Using a recent RISC-V board bring-up as a case study, the session details the end-to-end process from early boot to functional OpenGL acceleration, and gaps in current upstream support. Particular attention is given to PowerVR enablement hurdles on RISC-V, where ecosystem fragmentation and limited documentation still require significant groundwork.

Use both together and you are billed twice. This talk shows how we use self-hosted openSUSE containers for large codebases, and how we re-used it to eliminate that overlap. We walk through our Linux kernel testing pipeline: cache management, cross-architecture builds, checkpatch per-commit, and more. Then, we explore how we get the most of LLMs by running them inside the same container. Using pi.dev as the agent harness, we can swap the model, and tune the system prompt for one-shot requests. The agent runs after the top-level pipeline completes, with CI annotations (warnings and errors), being part of the prompt. The agent is instructed to assess the issues, and validate its claims by rebuilding and testing. As the output, it generates git patches, and summarizes the session into a structured review summary.

This talk presents grommunio as an open, enterprise-grade alternative to Microsoft Exchange, with a strong focus on the technology behind making it usable out of the box. The session will show how grommunio builds on the openSUSE ecosystem to deliver a complete collaboration appliance based on openSUSE 16.0, using KIWI to create a reproducible, maintainable, and deployable system image. Rather than only discussing groupware features, this talk goes behind the scenes: how the appliance is assembled, how openSUSE provides the operating system foundation, and how grommunio packages email, calendaring, contacts, mobile synchronization, Evolution/Thunderbird/Outlook compatibility, and administration into an integrated enterprise experience. A key focus is the out-of-the-box experience: turning a powerful open source software stack into a product that can be installed, configured, and operated by real organizations. The talk highlights how openSUSE technologies enable a reliable appliance model, how grommunio delivers enterprise collaboration on top of it, and why this matters for organizations that want to reduce vendor lock-in without compromising usability or professional requirements.
