openSUSE Tumbleweed now provides the Python interpreter and packages built for Python 3.6, 3.8 and 3.9. In this talk, I'll go through broadly how the interpreter is packaged, how module packages are built, how packagers can use the provided macros to their benefit, some sharp edges to watch out for, and what future plans we have. Please note: I am on the East Coast of Australia, so please be aware of that when scheduling. openSUSE Tumbleweed now provides the Python interpreter and packages built for Python 3.6, 3.8 and 3.9.

Technical documentation is like the box of bandages in your bathroom cupboard: you don't know it exists unless you actually need it. And as it happens, it's when you need it the most that you find it half empty... In this presentation we tell you everything you didn't know you wanted to know about the openSUSE documentation. You'll embark on a journey into the wild, from luxurious wikis to austere source-control platforms, where we'll try to widen your eyes on the importance of a central frame of reference, and on the numerous challenges standing in the way of discoverability and user-friendliness in the extremely rich and ever-evolving ecosystem of the openSUSE distributions. You'll be walked through the front line between users eager for technical facts and users eager for best-practices, and told about our approach, our ideas, and why you could actually have fun contributing.

When Uyuni started, it only supported SLES and RHEL as clients. In late 2018, Ubuntu was added. From there, it all went uphill: SLES Expanded Support, openSUSE, CentOS, Oracle Linux, Debian, Alma Linux, Amazon Linux, Alibaba Cloud Linux and Rocky Linux. As of today, Uyuni supports all the major enterprise Linux distributions. How difficult was that? Pau Garcia from Uyuni and Jack Aboutboul from Alma Linux talk about that.

You depend on scores of open source applications, frameworks, and libraries. One hasn't released for years. Another is struggling with a big rewrite or a difficult maintainer. How do you get a legacy OSS project unstuck? Especially if you don't already maintain it? I've done it and I'll share how. I've helped get several OSS projects unstuck. I'll share success stories (one only took 15 hours of work), and I'll discuss the 5 major ways OSS projects get stuck (strategy, team, interfacing, workflow, and money) and how to address each. And yes, a contributor who's never worked on the project before can be the catalyst that revives it or gets a long-delayed release out the door. You'll come away from this talk with steps you can take to rescue and renew OSS projects - regardless of language, framework, or platform.

The Fedora Project has been a diverse project since its advent. Fedora has been shipping Workstations, Servers, Cloud, and IoT operating systems as well as many more amazing things to engage developers, users, and innovators worldwide. In earlier years, Fedora outreach was primarily executed by a group of people referred to as Fedora Ambassadors. The Ambassador Program has had many success stories of community growth during its 15+ year history. However, as time moved on the program began to grow, but not scale and adapt. Different bodies of governance within Fedora had different ideas of how things should be run. With no scalability, participation in the program declined. This year, we see a pandemic sweeping across the globe and all events have gone virtual. There has been no better time to revamp the Fedora Ambassadors program, as well as the entirety of Fedora’s Community Outreach teams. The Fedora Action Impact Coordinator, Marie Nordin, created a team formulated of two co-leads, Mariana Balla and Sumantro Mukherjee, and a group of volunteers (Temporary Task Force (TTF)). This team will work to address the historical pain points, create a new vision for community outreach in 2020, and re-engage the various teams & the Fedora community. Attendees of this talk will learn about how we got here, how we came up with a proposal for change, and how it is being executed. We welcome anyone interested in Fedora, community, and outreach. Attendees can get insights into the Fedora Ambassador overhaul, learn how to get involved, and give constructive suggestions to help the Community Outreach Revamp succeed.

One of the more heavily underrated openSUSE projects is the [KIWI image builder](http://osinside.github.io/kiwi). In the last few years, [Datto](https://datto.com) has started using KIWI to replace the patchwork of custom image build tools to provide a consistent toolchain for producing various appliance images. This talk introduces the KIWI appliance image builder, outlines some of Datto's use-cases for KIWI, and how Datto uses KIWI to support those use-cases. This also includes a brief demo of building an image with KIWI. One of the more heavily underrated openSUSE projects is the [KIWI image builder](http://osinside.github.io/kiwi).

Do you want to promote Free Software in public administrations? Then the campaign framework of "Public Money? Public Code!" might be the right choice for you; no matter if you want to do it as an individual or as a group; if you have a small or large time budget. More than 200 organisations, and more than 29,000 individuals demand that publicly financed software should be made publicly available under Free Software licenses. Together we contacted politicians, decision makers, and civil servants on all levels -- from the European Union and national governments, to city mayors and the heads of public libraries about this demand. This did not just lead to important discussions about software freedom with decision makers, but also already to specific policy changes. Already, we have administrations from Spain, Sweden and Germany supporting “Public Money? Public Code!”. In the talk, I will explain how the campaign framework can be used to push for the adoption of Free Software friendly policies in your area; be it your public administration, your library, your university, your city, your region, or your country.

A common question about sudo and syslog-ng is how to send alerts to various online services. Both of these have supported sending email notifications for a long time, but more recently users have requested real-time alerting to Slack, Telegram, Discord and others. Peter’s talk will introduce you to alerting using the AppRise Python library. You will need to know a bit of Python and at least one of sudo or syslog-ng to understand the examples (openSUSE Tumbleweed was the first distro to enable Python support for both of these applications), but what you learn will help you to implement real-time alerting in a wide range of applications. First of all, what do we mean by alerting? It is sending notifications about important events in your IT environment. Traditionally, this meant receiving a flood of emails when a problem occurred. These days, there are many more services that can be used to receive alerts. You can send alerts to most of them through HTTP-based protocols. Syslog-ng has an http() destination that can be used to send alerts to various online services. However, even when a service’s API is published, figuring out how to actually use it can be difficult. The new python() destination makes it possible to connect to additional services through the use of client libraries, but still requires work for each new service. This is where the AppRise Python library can help. It supports most of the well-known instant messaging services in addition to many other, less well-known services. Once you integrate it into your project you instantly have access to dozens of services that you can send alerts to. Through the sudo and syslog-ng integrations you will learn how to work with AppRise. The included Python code focuses on functionality, but lacks proper error handling to make it easier to read. A live demo will show sending alerts to Discord and how easy it is to change the alerting to use other services.

Authentication and Identity Management are at the core of our systems security. Everyday we all authenticate to many systems, from out phones and laptops, to websites, servers and much more. Kanidm is a new opensource IDM system that is developing rapidly, and promises many new features previously only found in cloud and identity as a service platforms. This includes webauthn, claims, ssh management, and much more. In this talk we'll demonstrate many of the features of this platform, how it's begun to integrate with opensuse, how it was made possible, and what the future holds for this growing project.

In a world of online meetings and conferences there are many things we can't do at the moment, at the same time however we are doing far more online. So what can we do to make our experiences better whether its video conferencing, preparing talks, podcasting or recording youtube videos. At the same time this conferences format being online provides me with the ideal environment to talk about this with easy access to gear etc. From a technical perspective I will cover the following: * Using obs to create overlays during conference calls. * Configuring Jack * Using Calf audio plugins to improve your audio quality * Noise Gates * Compression * EQ * Using your computer as a guitar amp. Could probably also be a 30 minute talk instead. In a world of online meetings and conferences there are many things we can't do at the moment, at the same time however we are doing far more online.

Vier spannende Konferenztage gehen zu Ende. Ein gemeinsamer Abschluss soll erfolgen mit Rückblick auf die Konferenz und das erlebte. Natürlich auch mit einem Ausblick auf das nächste Jahr 2022. Wir fassen die 4 Tage zusammen und wollen ein paar Highlights hervorheben. Wir schauen auf 4 Tage Vorträge, Workshops, Demo-Sessions und Diskussionen auf der Bühne oder am Lagerfeuer zurück. Natürlich bedanken wir uns beim Team 2021 und senden herzliche Grüße an das Lokal-Team nach Rapperswil. Es wird ein Rückblick auf die erste FOSSGIS-Online-Konferenz und ein Ausblick auf die nächste FOSSGIS-Konferenz, die dann wieder vor Ort stattfinden soll. Nur wo? Es bleibt spannend. Den Sekt müssen diesmal alle selbst kalt stellen. Statt Sektempfang freuen wir uns nach der Abschlussveranstaltung auf einen Sektausklang - vielleicht sogar am Lagerfeuer. about this event: https://pretalx.com/fossgis2021/talk/YULPMW/
