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!

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!

By having a local mirror, we are trying to reduce the time it takes to download updates and software packages and by making it publicly available, we hope to bring more enthusiasts in our openSUSE community, in Tirana.

A technical breakdown of the openSUSE mirror on how we have designed the infrastructure to be secure, available and easily maintainable will be provided. Lastly, if you're curious about the openSUSE community in Albania, you'll definitely want to stick around! This talk will be about the creation of the openSUSE mirror in Open Labs Hackerspace. By having a local mirror, we are trying to reduce the time it takes to download updates and software packages and by making it publicly available, we hope to bring more enthusiasts in our openSUSE community, in Tirana.

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.

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.

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.

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.

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.

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?

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.

Wouldn't it be nice if you could download repositores locally and update from a machine on your own LAN? Benefits include much faster updates, more control over local updates, and less cluttered WAN traffic. In this talk, I will go over the setup and benefits of running a local Repository Mirroring Tool (RMT) instance on openSUSE Leap, that can serve all your other systems' update needs. This aims to be a comprehensive guide, covering all the specifics of RMT setup locally: hardware requirements; downloading the pattern to allocating disk space; setting up systemd unit files and timers; subscribing your other systems to the RMT server; and some simple troubleshooting for commonly observed issues. RMT is an opensource tool available from SUSE written in Ruby. The setup for RMT is currently lacking in documentation for openSUSE specifically. Consider this a first step in making a more specifically open version of RMT (i.e. at present the "client subscription script" fails when it calls proprietary SUSE URLs).

With containerd as the backend and nerdctl as the frontend there is now a new contender in the container runtime ecosystem challenging both Podman and Docker. In this talk, we will introduce containerd, a lightweight and flexible open-source container runtime, and nerdctl, a command-line interface for containerd. We will then take a look at these two tools together as an alternative to both Docker and Podman, especially taking a look at new and exciting features implemented in nerdctl. Be sure to join this session to find out how nerdctl can accelerate rootless container networking, encrypt your images and much, much more! While Podman started out as a replacement for Docker, it has now become a well-established container runtime. With containerd as the backend and nerdctl as the frontend there is now a new contender in the container runtime ecosystem challenging both Podman and Docker.

Also curious to know how other projects in the Kubernetes ecosystem do this? If so, you will love this Kubetest2 session. Kubetest2 is a testing framework maintained by Kubernetes SIG Testing that allows you to test Kubernetes code changes both locally and on the cloud. It manages cluster configuration, e2e testing, log collection, and test environment disposal. Kubetest2 natively supports GCP, GKE & KinD deployers, but also enables writing custom deployers out-of-tree. A custom Kubetest2 deployer is possible, but it needs some prior context & knowledge of Kubetest2 internals. To that end, this talk will provide attendees with the following takeaways: * What is Kubetest2, overview of its architecture, and its evolution from its predecessor Kubetest * Benefits of using Kubetest2 as a testing tool for your project * Reasons to use a bespoke Kubetest2 deployer * And, a step-by-step demo for constructing a custom kubetest2 deployer for your own cloud provider Slides available at https://psaggu.com/assets/osc2023/k2p.pdf Do you want to test Kubernetes end-to-end on your cloud?
