Mailinglisten sind ein wichtiges und weit verbreitetes Kommunikationsmittel im Clubumfeld. Die Bedienung ist oftmals aber nicht ganz intuitiv. In diesem Petit Foo werde ich einige Hinweise geben und Tricks erklären die einem den Umgang mit Mailinglisten erleichtern. about this event: https://www.chaospott.de

Alle wollen das Upgrade. Etwas, um das Leben noch ein kleines bisschen zu verbessern. Aber wie finden wir dieses Upgrade überhaupt? Doch es gibt nicht nur Upgrades. Bei Themen wie Daten, digitale Wirtschaft, Medien, Politik oder Manipulation wird deutlich, dass Upgrades manchmal auch Downgrades mit sich bringen. Wie können wir im Labyrinth neuer technischer Möglichkeiten Upgrades von Downgrades unterscheiden? about this event: https://www.chaospott.de

Openess have reached the banking. From opensource, to openhardware and now openbanking, but, does OpenBankig is OpenSource? The answer is not so much. The OpenBanking specification is open, but here are no OpenBanking Implementation. Do we can make a OpenBaking implementation only with OpenSource? Definitivealy yes. We will explain what OpenSource tools do we used to implement Openbaking and leverage it to the cloud. We will talks about the user benefits of OpenBanking Then we will make an overview of the OpenProtocols used at OpenBanking, as Oauth2. Finally we will explain what tools do we selected to implement openbanking in an open and fashionable way. Join us in this journey. Openess have reached the banking.

Following on from the brief introduction at the LibreOffice Summit, I will re-introduce Firebird, the open source version of Interbase, the original embedded systems database. Firebird is a high performance, small footprint database with a long (and interesting) history. Firebird features Stored Procedures, Transactions, Encryption, multi user access, and is SQL-92 compliant, and can handle databases as large as _20 terabytes._ Because of its small size, efficiency multiplatorm nature, Firebird is ideally suited to IOT and edge device deployments, at any tier of system architecture. I will go through the steps required to prepare new database for production and multi-user operations, using a simple Django deployment as an example.

**Avahi: free configuration for your network service.** _(Live demo included) If you've wondered how your Desktop Linux machine "discovers" items on your network, such as printers and file shares, this session will explain Avahi: the network service advertises resources across a LAN. The open source version of Apple's Bonjour/Zeroconf, is a very flexible way to enable discovery of services. We'll discuss how we used it in our deployment tooling , and we will demonstrate how to craft a configuration to discover custom resources for consumption by client software - enabling a true zero touch service installation. Basic networking and python knowledge advantageous, but not essential. **Avahi: free configuration for your network service.** _(Live demo included) If you've wondered how your Desktop Linux machine "discovers" items on your network, such as printers and file shares, this session will explain Avahi: the network service advertises resources across a LAN.

Do you know difference between starting mariadb vs postgres server as a regular user? Or apache vs nginx? Or maybe want to know specifics of working example of starting rsync server? There is no difference and no specifics - just use generated start / status / stop scripts. And there is more: (spawn as many services as needed(\*), configure ssl for cluster, build services from source, ...) - without affecting your system(*). environs framework suggests a universal approach for managing various services by generating bash wrappers, with following benefits: - object oriented approach - it hides internal specifics of service handling and allows an easy way to review and tweak them; - brief scripts for complex scenarios in complex topologies, without privileged access to the system; - easy to compare behavior of verious topologies; - demonstrate "how-to" behavior, share reproducible cross-product scripted scenarios in bug reports or TDD / BDD; - no OS flavor limit - run everywhere where shell is(*); - no extra dependencies - run in cloud, container, VM, CI or local machine. The main goal behind environs framework it to cover early integration testing and provide a way to script and share cross-product behavioral scenarios without root access to the system. So far the framework includes scripting possibility for postgresql, apache, nginx, rsync , mariadb(*), openQA, MirrorBrain, MirrorCache, zypper.

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).
