Well Hello Friends! Das SerenityOS-Betriebssystem – nie davon gehört? Kein Wunder, denn das Projekt um den schwedischen Entwickler Andreas Kling baut erst seit 2018 von Grund auf ein unix-artiges Desktop-Betriebssystem. SerenityOS ist nicht nur kein Linux und hat nicht nur einen 90er-UI-Stil, sondern ist auch dank vieler weiterer Aspekte ein sehr interessantes Open-Source-Betriebssystemprojekt. Kleines Filmröllchen ist langjährige*r Mitarbeitende*r bei SerenityOS und führt euch in diesem Talk von Kernel bis Browser quer durch System und Projekt. about this event: https://cfp.events.hacknang.de/fsck-2023/talk/NPXC7X/

Diese Programmiersprache mit dem Namen "Rust" ist in aller Munde. Warum eigentlich? In diesem Talk möchte ich darstellen warum es noch eine Programmiersprache braucht, was es mit dieser auf sich hat, und warum diese evtl. interessant sein könnte. Der Talk wird keinen Code beinhalten. Dieser Talk ist kein Intro zu Rust, sondern vielmehr eine Entscheidungshilfe ob Rust einen Blick lohnt und warum. about this event: https://cfp.events.hacknang.de/fsck-2023/talk/JCHDC9/

Multimedia support in openSUSE has always been a bit of a patchy affair. The community wants to have a useful and usable experience on the multimedia-rich environment out ther today, from user-generated video content to video conferencing with friends and family. Until recently, this has been difficult to offer in openSUSE. But now, there's hope! With the introduction of an approved AAC codec and an arrangement with Cisco for an H.264/AVC codec implementation, we're on the road to having much better multimedia capabilities in openSUSE. This talk will discuss the _status quo ante_, what was done to change that, and where we're going to make openSUSE rock even more!

When I published a LinkedIn post on Croatian open data last summer and how we use the PostgreSQL based Aranei as a data processing and profiling tool, I could not have imagined the snowball effect turning into an avalanche of reactions that was triggered by that post. Open Data is obviously a topic many people and organizations have many insights on and opinions about. The result of a relatively modest import of Croatian open data sources into our Aranei data management platform resulted in an international group of interested and helpful people. After many considerations and many more conversations, we feel that it is actually part of a triad of concepts that need to be treated holistically. Open data cannot exist without open standards, and open standards are connected to open-source software. Open-source software is part of the technology stack for publishing open data, and there we have a nice circle. Using our fully open source stack of Aranei, consisting of PostgreSQL, PHP Symfony framework / API platform, React-Admin and many more free software components, we’ve visualized and contextualized the Open Datasets from the Croatian government, showing how much more insights can be gained about the data when normalized and correlated properly. We decided to turn our experience into a movement, called OpenDataConnected. Here we’re connecting the open data publishers, with the advocates and evangelists, and with the eventual organizations that use those open datasets. We’ve reflect on some of the findings on our experiences with the Zagreb/Croatian open data, we want to work together with this community on how to define value propositions from those datasets and most important we want to have an open conversation with you, OpenDataConnected participants on which topics are of interest to you for the next couple of months. On our annual DORS/CLUC conference in May in Zagreb, we will then have a fully inclusive OpenDataConnected track to bring all those pieces together!

Since last year’s talk i’ve been working on modernising conky’s default config system. There are a number of reasons for doing this from being able to provide a default configuration that better adapts to the system hardware to making it much easier to provide a modern look and feel. In this talk i’ll talk about the parts of this process that were easy because thanks to open source someone had already written something, the frustrating parts because someone had created something really nice but not licensed it. I’ll also talk about all the unexpected detours that I took which included some lua packaging, learning to write lua bindings and learning how to do proper font rendering on linux. I’ll also share the current progress and how you can give it a shot yourself along with what still needs to be done .

The MicroOS Desktop started as a hairbrained, poorly thought out, "lets see what happens" concept at an openSUSE Conference not so long ago. It's since become perhaps the most stable, reliable, and exciting Desktop offering the openSUSE Project offers. This brief talk will provide a brief overview of the MicroOS Desktop project, advice for newcomers to the platform, and an open invitation as to how to contribute to help make openSUSE's latest and greatest Desktop OS even better. Africa's internet speed is below the global average and that gives us a stronger reason why we need more mirrors in the continent. In this presentation I'll explore how we built two additional openSUSE mirrors in Africa during the past year and what can be done to improve this picture, and reach out to more users in the continent.

For those who use Linux professionally in companies, proxy servers are a horror. Under Linux there is no central configuration of proxy servers and each major library / programming language implements its own implementation. If login data and so-called PAC proxies are added, which serve not only one but several proxy servers, it gets really complicated. This is where the library libproxy comes in and tries to solve this problem. By providing a simple and stable API it answers the question: Which way do I have to take to reach XYZ? In this talk we will present libproxy, its current state and future development. Together we can solve the problem and bring this solution into the enterprises, so that Linux becomes even more integrated and established in the professional environment and their complex processes.

OpenSUSE MicroOS, SLE Micro and the SUSE Adaptable Linux Platform (ALP) have moved to using SELinux for Mandatory Access Control (MAC). There are some key differences between a traditional Linux system without MAC, and one with SELinux. Furthermore, using SELinux on transactional systems such as openSUSE MicroOS and ALP-based distributions has its own peculiarities. In this talk we will introduce SELinux, describe what it does, and show how to work with it. We will then see how it's used on a transactional immutable system such as an ALP-based distribution, where most workloads are run inside containers. This talk is for a beginner to intermediate-level audience. You should have a general understanding of both traditional and immutable Linux systems, but won't need specific SELinux expertise.

After 13 years, a new major release of the syslog-ng logging application is available. Syslog-ng 4.0 brings type support and many additional enhancements. This presentation also gives you an overview of some of the larger features since the previous major release, and then proves why type support is a major enhancement, improving both operations and security. In version 3 and earlier, syslog-ng handled all data as text. Syslog-ng 4 can associate the proper type information with data parsed from log messages using the JSON or PatternDB parsers. You can use type information for comparisons within syslog-ng, and storing data to various destinations, like Elasticsearch or MongoDB. Type support enables more precise filtering and thus real-time security alerting in syslog-ng, and easier searching and reporting in databases. I give a quick overview of the major new syslog-ng features during the version 3 series, including disk-buffer, message parsing, Python support, HTTP destination, Kubernetes support and how these combined with 4.0 features improve both operations and security.

When using **Xorg**, in order to have a headless remote session we could use **Xvnc**, and it worked great. You can start with it a headless **Xorg** display, on top of it use any desktop environment or just run a **Xorg** client and access it using **VNC** protocol. Now with **Wayland**, the display server is also the windows manager/compositor so there isn't just one single display server to use any desktop environment but each desktop environment has its own **Wayland** compositor implementation. In this talk, I will explain my quest to have a **Wayland** headless remote desktop using the **RDP** protocol in the **GNOME** environment. Most of the work I'm doing is on this [MR](https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/merge_requests/139). When using **Xorg**, in order to have a headless remote session we could use **Xvnc**, and it worked great. You can start with it a headless **Xorg** display, on top of it use any desktop environment or just run a **Xorg** client and access it using **VNC** protocol.

systemd-boot is a rather simple UEFI boot manager. Using it instead of grub might be desirable in the future. The combination with btrfs snapshots makes things more complicated though. This talk gives an introduction to systemd-boot and the challenges to fully integrate it into openSUSE. systemd-boot is a rather simple UEFI boot manager.

Everybody of us have got a laptop. Then there are some Embedded enthusiasts with arm hardware. Did you hear already about the architecture s390x for mainframes, which includes IBM zSystems and LinuxONE? You will learn, where such hardware is used and that you can also still use it with openSUSE. Hints will be given, how to receive mainframe access for free for open source development. Finally, there is a short introduction, how you can be included for better s390x support (with feedback) within the Linux Distributions Working Group at the Open Mainframe Project.

BCI (Base Container Images) is a set of open-source container images that developers and operators can use as a foundation for containerizing applications. BCIs cover a wide range of use cases and scenarios compared to traditional enterprise distribution images. We had to take a different approach to testing and delivery to cover all these new use cases. In this session we briefly cover the history of the Base Container Images and the tooling that we created in the process. This includes our [Dockerfile generator](https://github.com/SUSE/BCI-dockerfile-generator), the [BCI test suite](https://github.com/SUSE/BCI-tests/), and the [`pytest_container`](https://github.com/dcermak/pytest_container) plugin. We also take a look how we moved the development from our internal build service to the [public Open Build Service](https://build.opensuse.org/project/subprojects/devel:BCI) and then to [Github](https://github.com/SUSE/BCI-dockerfile-generator).

We are using SALT to deploy SUSE Systems for production. The included modules work well for usual problems. But what needs to be done if you want to integrate a software system (or part thereof) where there are no modules available? Calling out to shell commands won't work to well for complex tasks. You'll find the slides at https://www.jochen.org/vortraege/implementing-salt-modules.pdf We've implemented - as part of a bigger automation effort - some SALT modules to configure our SAP HANA applications for better integration into the automation machinery. I'll present our motivation for implementing execution and state modules, how you can start implementing and testing them. In my experience the function signatures of the modules are the key to useful state modules, so I'll take a look at our modules and discuss the experiences gained in using them. Is the effort worth the gain? My answer is "yes". Some basic programming skills and Python will be helpful for understanding, but not required.

Rancher can deploy and manage your Kubernetes clusters on AWS EKS and EC2. But what about things like Authentication, Logging, Monitoring or Backup? I will give an overview of AWS services for these four pillars and talk about what’s already possible, which challenges some integrations might have and an outlook what’s planned. Learn more about how the integrations are working under the hood and which technologies and open-sources solutions are involved.

This talk will cover the development of an openSUSE based external-dns solution that can be used within a k3s environment. The current upstream solution for external-dns is based on Alpine Linux. In order to create containers based on openSUSE, powerdns and external-dns containers were developed and published to registry.opensuse.org. During this session, the different design decisions and hurdles that were overcome will be covered. In addition, the presentation will provide tools, tips, and troubleshooting techniques that were used during the development cycle.

With SUSE's ALP stirring up discussions how Linux distribution may look like, we decided to try different approach how installer may work. Part of these installer try-outs is **Iguana** - installation initramfs where all heavy lifting is done in containers. Moving installers to the containers and by leveraging container infrastructure, we are trying to solve ever changing requirements or need to have security and other fixes in installer, which was always a bit of challenge for relatively static things like OS installers.

Packaging for a distribution means taking sources from upstream projects, applying fixes and modifications, adding some configuration and then build the result by calling some commands. RPM formalized the process following a "pristine sources" model. The approach is basically to take the unmodified sources as released by upstream and store required changes in the form of patches as well as a build description next to them. Times have changed. The distributed version control system git dominates the free software world. Juggling tarballs and manually applying patches is no longer a natural workflow. Packager life could be much easier if downstream changes could be applied by means of git too, skipping tarballs. This talks presents a way how to apply the pristine source idea to a git based world, without history rewriting in the distro repo.

Both the ISO 27001 and ISO 27002 standards have been updated in 2022. What does this mean for open source communities and companies leveraging open source? What are the most significant changes to the standards? The new ISO27001 standard requires companies to identify and meet the needs of interested parties, such as customers and suppliers. That way, organizations can ensure that their information security management system is designed to meet their stakeholders needs. It also requires that organizations include processes for managing information security objectives in their ISMS, so that those objectives can be monitored and evaluated over time. It is essential for organizations to be able to demonstrate that their data-protection and security risk mitigation measures will be maintained and continuously improved. The new ISO27001 standard also makes it clear that changes to an organization's ISMS must be planned, with a specific process for communicating those changes to interested parties. This process should establish how communication should occur (rather than just who should communicate). Organizations now have to control processes, products, or services that are outside of the ISMS (as well as those that are inside of it), which means that they have to take a more holistic approach to managing both internal and outsourced operations. ISO 27002 has been updated, firstly the phrase 'code of practice' has been dropped from the title of the updated ISO 27002 standard. This approach better reflects the set's intended purpose as a reference of information security controls. The 27002 Standard itself is considerably longer than the previous version, and the controls have been reordered and updated. The new controls are identifiable by attribute, which makes it easier to focus on relevant categorical selections, which could reduce the compliance burden or help better integrate information security processes, making the ISMS easier to implement and manage. What is a reasonable for IT vendors and open source communities to update their cybersecurity approach to reflect the new requirements from the new norms?

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 [Download the slides of the talk here](https://download.fsfe.org/presentations/20230526-mk-opensuse-ada-zangemann-reading.en.pdf) and you generic slides for doing your own readings with the book are available [in the FSFE's book repository](https://git.fsfe.org/FSFE/ada-zangemann).
