The famous inventor Zangemann lives in a huge villa high above the city. Adults and children alike love his inventions and are desperate to have them. But then something happens: when Zangemann wants to take another close-up look at his inventions during a walk through the city, a child hits him in the shin with the skateboard. That hurts! Enraged, the inventor makes a momentous decision... The clever girl Ada sees through what is going on. Together with her friends, she forges a plan.

This illustrated children's book (licensed under Creative Commons BY-SA) tells the story of the famous inventor Zangemann and the girl Ada, a curious tinkerer. Ada begins to experiment with hardware and software, and in the process realizes how crucial it is for her and others to control technology. Ada & Zangemann will inspire children's interest in tinkering and encourages shaping technology.

> "A rousing tale of self-reliance, community, and standing up to bullies." —Cory Doctorow, Sci-Fi Author

> "Ada & Zangemann proves that the argument for software and hardware freedom is simple: We should be able to do what we want with our stuff. . . . Electronics freedom means more learning and less waste, as Ada shows. Kids and adults alike will be entertained by this book, charmed by its illustrations, and inspired by Ada’s engineering spirit and impassioned activism."

—Elizabeth Chamberlain, Director of Sustainability, iFixit

> "What a fun read! I recognize myself in Ada at many moments." —Isabela Fernandes, Executive Director, The Tor project

> "Even as a non-child, I was captivated by the story from the first page to the last. Kudos to the author for packaging difficult topics such as monopolies, lobbyism, digital divide, software freedom, digital autonomy, IoT, consumer control, e-waste and much more in a child-friendly form in an easily understandable and exciting storyline." —Jörg Luther, chief editor of the German Linux-Magazin, LinuxUser

The Open Build Service can build just about everything from any source imaginable, including container images from a `Dockerfile` or a kiwi build description. But as usual, the devil lies in the details, and just pushing a `Dockerfile` to OBS would often lead to odd errors that do not occur in a local build.

This talk covers the basics of building container images, best practices to follow as well as certain corner cases that you never wanted to know about, but might run into anyway. Come join this talk, so that you can start deploying and stop worrying about your container images ever getting out of date!

How does the latest prototype of the Adaptable Linux Platform behave on AWS? What is required to build a EC2 compatible image via OBS? How does the workflow look like to go from OBS to an available and deployable AMI? What is the state of integration with AWS compared to openSUSE Leap? And what has SUSE NeuVector todo with all that? Let me take you on my journey and share my experiences, thoughts and results with you.

This session will present the latest news from the development of the next-gen SUSE Adaptable Linux Platform. We will cover both technical aspects of the platform as well as discuss implication for the Leap successor product.

This session is recommended to attend before joining the panel discussion about ALP.

There are multiple Source code management systems online today, systems like GitHub, GitLab, etc. They are widely used to manage your package sources. With the help of SCM/CI workflows, you can integrate an SCM with OBS and run different workflows. For example, on creating a new pull request, build a package on OBS and report back to SCM.

The focus of the talk will be introducing SCM/CI integration. We'll present an implementation of a simple workflow and explain its limitations.

Scientific research relies heavily on software to analyze the vast amounts of data that are generated every day. But unfortunately, software development is not supposed to be part of a scientific career. Funding is usually granted for developing new algorithms rather than providing user-friendly features or maintaining software. In this talk, I will share our story of how scientific software can benefit from spinning out a software company.

Our software identifies molecules in biological samples and enables researchers to detect toxic compounds, find molecules indicating diseases or discover the next drug candidate. For many years we have been developing the underlying algorithms based on combinatorial optimization, statistics and machine learning, in an academic context. We started as PhD students and postdocs at the University of Jena, and in 2019, we founded a spin-off company, Bright Giant GmbH, to provide services based on this software. This allows us to provide better support and implement features that are highly valuable to users but not of scientific novelty.

A big part of the software is open-source and free to use for everybody. Furthermore, our SaaS is offered to the academic community free of charge by the University of Jena. With the right balance between free and commercial software, as well as open- and closed-source software, spin-off companies can accelerate scientific research.

Podman is a wonderful tool to work with containers. Podman containers can

easily be managed as a systemd service. Podman can generate the systemd unit,

so the user does not have to.

In case you are managing your infrastructure and configuration with Ansible,

you can also create the Podman container configuration with Ansible, thanks

to the containers.podman collection.

This talk gives a short introduction in both Podman containers and Ansible.

The RISC-V ISA is highly modular with cpu vendors being able to pick from a number of standardized extensions and even invent their own.

Yet we want a unified kernel Image and userspace that does not have to care about which extensions are available but still is able to use them.

So after showing where this matters, I want to introduce some techniques the kernel has in its lower levels that allows us to do this performantly.

The DNF package manager has been available in openSUSE for some time now, providing all kinds of useful functionality and enabling a consistent software management experience across RPM distributions.

With DNF version 5 coming later this year, what does this look like from the perspective of an openSUSE user? Is this finally the version that brings us to a unified package manager for RPM distributions?

This talk will discuss how DNF version 5 in openSUSE looks and provide a demonstration of an openSUSE system with it in place.
