Today we will talk about Linux Mirrors. What do people use them for? Why they could use a (tiny bit) of modernization? What are the security implications? Where are we now and where do we plan to go? We will show you what we have done to take care of these concerns, how far we’ve gotten and our vision for the road ahead. We want to hear about everyone's opinions on what we’re doing well and more importantly on what we’re doing wrong. Today we will talk about Linux Mirrors. What do people use them for?

Uyuni is a configuration and infrastructure management tool that saves time, costs and headaches when managing and updating tens, hundreds or even thousands of machines. With automated patch and package management, it enables the deployment of patches and packages based on software channels and repositories that can be assigned. Uyuni makes it easier to onboard and manage any Linux server connected to the network, from IoT edge devices to Kubernetes environment, no matter where it is located (private or 3rd party data center or in the public cloud). Uyuni is a single tool for automated deployment of hardened OS templates (bare metal/VM/container) to tens of thousands of servers and IoT devices for faster, consistent and repeatable provisioning and configuration without compromising speed or security. The CVE audit feature allows to check the status of public security patches and with OpenSCAP it's also possible to check for specification compliance and apply remediations right from Uyuni.

In the last years we worked hard at automating (technical) IT processes. In the talk I'll reflect what we did, what went well and what didn't work out. We now see that the next big challenges won't be the technical stuff - that's s "solved problem". We face a couple of challenges: - Reducing manual overhead in planning/preparing - Integration in ITSM processes especially change and incident - Automating manual processes or eliminating them. We'll view at some tools that may help us, but the biggest challenge will be a change in the mindset: How can we reduce work (possibly to zero)?

The year 2038 problem (also known as Y2038) is a time formatting bug on Unix systems with representing times after 03:14:07 UTC on 19 January 2038. This happens with a 32bit time_t, not with a 64bit time_t. The general statement so far has always been that on 64bit systems with a 64bit time_t you are safe with respect to the Y2038 problem. But this isn't correct: on bi-arch systems like x86-64 (so which can execute 64bit and 32bit binaries) glibc defines __WORDSIZE_TIME64_COMPAT32, which leads to the fact, that struct utmp (used for utmp, wtmp and btmp) and struct lastlog uses int32_t instead of time_t. So we have a Y2038 problem, which is not easy fixable, as this would require ABI and on disk format changes. In this talk I will speak about the background, which tools are affected and how we solved that in openSUSE by dropping utmp, wtmp, btmp and lastlog completely and make use of systemd-logind and other tools instead.

Nextcloud is the most popular self-hosted, open source collaboration platform for a reason. I'll go over some of those reasons, but more importantly, show and tell what Nextcloud can do for you. As home user, small business or big business (but an emphasis on the smaller side of things). Why should you care? A small handful of big tech firms are gathering up the data of nearly everybody on this planet. They use every trick at their disposal, from pricing to gate keeping, to make sure nobody gets in. And with our data comes not only a massive opportunity to squeeze profits out of everybody using digital devices, they also give a variety of 3-letter agencies a treasure trove of data to use for profiling and worse. But the good news is that, while Big Tech prefers everyone thinks otherwise, there is a real alternative to MS 365 and Google Workspace. If you are new to Nextcloud, this will be a great introduction. If you're aware of Nextcloud, I'll show you what it can do. And if you're very familiar with Nextcloud you'll still learn some things you didn't know! Nextcloud is the most popular self-hosted, open source collaboration platform for a reason.

Das"Transsexuellengesetz" ist Geschichte, soweit so gut. Was das neue Selbstbestimmungsgesetz, dass im November in Kraft tritt aber überhaupt bedeutet, was es mit der Anti-Gender-Ideologie von Rechtsaußen zu tun hat, und warum es Geflüchtete, Transfrauen und Menschen unter Betreuung besonders hart trifft, erfahrt ihr bei diesem StandUp-Theory-Theatre. Es geht - nicht nur - um Nazis in der Sauna! Ihr könnt direkt vor Ort, live und in Farbe, euren Personenstand und Namen ändern lassen und dabei in die Untiefen des Entdemokratisierungsdramas einsteigen. Ihr dürft Euch sogar den rechtlichen Rahmen aussuchen: Gesetz der Bundesregierung oder queerokratische Alternative?

Ultimately, packaging is the right way to distribute and run software maintenance. But at the same time, there are very good reasons why in the Embedded world, images are often before package repositories. These reasons evolved over a very long time and did not change since. A number of typical problems, such as software bloat, configuration drift, broken updates etc are unacceptable in embedded systems as they may cause severe errors, ultimately "bricking" devices. Therefore there are specific practices to ensure those typical requirements for the embedded systems, those can be very beneficial also in other niches. If Edge Computing is on very constrained resources, there is actually a way to solve those "regular" problems, having maximum flexible and configurable solution, without _specifically_ developing a different, special distribution. This talk is intended to outline the following questions: - What are those earlier mentioned practices? - What is the benefit applying them and why does it matter? - Why Yocto Project is designed the way it is, and what part can be applied in SUSE world? - What is still missing in the process and what can be done so the result meets the requirements? **Spoiler**: _Keep it as simple as possible, but not simpler!_ :-) .

RPM packaging is a foundation of the software delivery mechanism on RPM-based Linux distributions, with RPM spec files acting as blueprints for package builds. Despite their enduring relevance, support for editing RPM spec files has not evolved significantly over time, leaving users with rudimentary tooling. In response to this challenge, we have developed a prototype of a language server tailored specifically for RPM spec files. Based on a language server protocol, the solution offers a unified editing experience across various editors, giving users features like auto-completion, linting, and jump-to-definition. All of this is achieved by centralizing "code smarts" in one place. Join us to learn about the thinking behind the language server and the challenges we faced when implementing this new tool.

Progressively, there are more and more [risks](https://jarnoduursma.com/blog/the-risks-of-artificial-intelligence/) associated with computer intelligence, and as a transparent software company we at Nextcloud have the responsibility to intervene and protect our users. [Microsoft laid off its entire ethics and society team](https://www.theverge.com/2023/3/13/23638823/microsoft-ethics-society-team-responsible-ai-layoffs), the team that taught employees how to make AI tools responsibly. Nextcloud on the other hand, embraces the ethics and challenges that make up today’s AI and aims to take them head on. The field of AI is moving fast, and many of the new capabilities face ethical and even legal challenges. Moreover, many people ask WHY do you need it in the first place.

Yet, while there is a large community developing ethical, safe and privacy-respecting technologies, there are many other relevant technologies users might want to use. We want to provide users these cutting-edge technologies – but also be transparent. For some use cases, ChatGPT might be reasonable, while for other data, absolutely not. To differentiate these, we developed an Ethical AI Rating. I will describe how our Ethical AI rating works, and give a bunch of examples. And, as a bonus, show how it is integrated in Nextcloud and how it can help you get work done - without leaking your data! I look forward to any feedback you wonderful folks in the audience have.

Yet, while there is a large community developing ethical, safe and privacy-respecting technologies, there are many other relevant technologies users might want to use. We want to provide users these cutting-edge technologies – but also be transparent. For some use cases, ChatGPT might be reasonable, while for other data, absolutely not. To differentiate these, we developed an Ethical AI Rating. I will describe how our Ethical AI rating works, and give a bunch of examples. And, as a bonus, show how it is integrated in Nextcloud and how it can help you get work done - without leaking your data! I look forward to any feedback you wonderful folks in the audience have. about this event: https://c3voc.de

End of March 2024 we faced the biggest supply chain attack we seen so far in the Open Source Ecosystem. A dedicated attacker had launched a multi year effort to backdoor the xz compression library. openSUSE Tumbleweed contained the backdoor for 3 whole weeks before an outside researcher found it. We will give a report on this attack, our reaction on it and also go into some future considerations to detect or avoid these kind of sophisticated attacks.

openQA is one of the key elements that ensures the delivery of updates and new versions of operating systems, it is the heart of openSUSE's effort to deliver stable systems for our users, and SUSE's quality gate, used to ensure that updates and new releases of the operating systems aren't breaking operations of customers; however it is growing outside openSUSE, Fedora and SUSE, expanding to other distributions, so we need to start thinking how to collaborate further, and have a clearer picture for users of openQA's ecosystem and integration capabilities. The speaker will give a quick overview of features, challenges and opportunities for further development, but also, wants to provide a window into how to close the gap between users outside of openSUSE/SUSE and the openQA development team Santiago Zarate is the Product Owner of [Quality Engineering Core team](https://progress.opensuse.org/projects/qa/wiki/Core#Scope-of-QE-Core) at SUSE, they collaborate closely with the [Quality Engineering Tools Team](https://progress.opensuse.org/projects/qa/wiki/Tools#Team) and rest of the teams of the Quality Engineering department To know more about openQA - [Talk: Shortening the feedback loops between R&D and the real world with openQA @ SUSECON 2022](https://youtu.be/3HN61L7RzzA?si=cFKT5JkujLc-w3_n) openQA is one of the key elements that ensures the delivery of updates and new versions of operating systems, it is the heart of openSUSE's effort to deliver stable systems for our users, and SUSE's quality gate, used to ensure that updates and new releases of the operating systems aren't breaking operations of customers; however it is growing outside openSUSE, Fedora and SUSE, expanding to other distributions, so we need to start thinking how to collaborate further, and have a clearer picture for users of openQA's ecosystem and integration capabilities.

Radikale Therapie hat alles was wir gut finden: Selbstorganisiert, hierarchielos, heilsam, radikal. RT ist eine sozialkritische Gruppentherapie, aufbauend auf Co-Counselling und Aspekten der Transaktions-Analyse. Statt einzeln zu therapeutischen Institutionen zu rennen oder unendlich lang auf einen Therapieplatz zu warten, trifft sich eine gleichgesinnte Gruppe in einem geschützten Rahmen, um sich selbstbestimmt über Machtstrukturen und kulturelle und soziologische Prägungen auszutauschen und Wege zu finden authentisch, frei und gut zu sich und anderen zu sein. Hier lernst du erste Methoden kennen und erfährst, wie du eine solche Gruppe finden und gründen kannst. Language: DE Translation: EN Recording: NO Are you tired of therapists who do not understand your worldview? Have you been unsuccessful in trying to phone your way through an endless list of therapists or are you lacking the success mindset of paying for your therapy as a private luxury? Or maybe you just want to exchange with cool, like-minded people in a safe space about the shit that is happening in our society, about societal and political power strutures, cultural and sociological imprinting as well as finding ways to be authentic, free and good to yourself? Then Radical Therapy (RT) could be your thing. RT relies on methods from co-counselling, expanding them with theory from the radical psychiatry of transactional analysis. You will have the opportunity to get a glimpse into elements of RT. Also, of course, you will learn how to find or start a respective group.

Mit dem Aufkommen von Social Media und Blog Posts erhielten plötzlich alle eine Stimme. Diese neue digitale Öffentlichkeit bietet aufregende Möglichkeiten zum Austausch und gegenseitigen Informieren. Gleichzeitig sind wir mit neuen Problemen konfrontiert: Digitale Hassrede und Beschimpfungen stellen etablierte soziale Normen in Frage. Was können wir dagegen tun? Vorgeschlagene Lösungen beinhalten oft Zensur oder Deanonymisierung im digitalen Raum. Aber gibt es vielleicht auch andere Wege, um den digitalen Dialog vor der Verrohung zu retten, und die digitale Öffentlichkeit wiederherzustellen? Am Netzpolitischen Abend erzählt uns Sophie Achermann, Leiterin und Mitbegründerin der Public Discourse Foundation, was es für einen gesunden medialen Diskurs braucht, und welche Rolle die Medienhäuser dabei spielen. about this event: https://www.digitale-gesellschaft.ch/event/netzpolitischer-abend-zu-hass-im-netz/

Präsentation der Projekte anlässich des «Jugend hackt» Events vom 14 bis 16 Juni 2024 im Hackerspace «Bitwäscherei» in Zürich. In «Evolution City» können die Spieler:innen Kraftwerke bauen, um Strom zu produzieren, womit sie wieder Geld verdienen, um neue Kraftwerke zu bauen. Allerdings steigt der CO2-Gehalt in der Luft bei jedem Kraftwerkbau entsprechend dem Bautyp. Wer 10 Minuten überlebt, ohne zu viel CO2 zu produzieren, gewinnt. Mit «Sicherheit auf die 1!» wurde eine Alarmanlage entworfen, bei der ein Sensor durch einen Micro Controller ein hörbares Signal auslöst, wenn es in Kontakt mit Licht kommt. Das Signal kann über Internet weltweit über eine Webseite empfangen werden: «So kann man immer und überall wissen, ob jemand in den Raum eingetreten ist oder nicht». «trainCCI» - ein alternativer Weg zur Reiseplanung bei instabiler Internetverbindung. Dabei können Reisewillige Abreiseort, -zeitpunkt und Zielort über einfache Kommandozeilen eingeben und erhalten dann – einzig diese Abfrage bedarf Internetanschluss – die entsprechenden ÖV-Verbindungen. Bei «Quack Snacks» geht es schliesslich um gesunde Ernährung. Im Spiel können Gamer:innen in einem Restaurant zum Beispiel zwischen einem Burger und einem Salat wählen. «Wählst du den Salat, wirst du upgegraded, gesund und sportlich.» Nach der Wahl des Burgers erscheint eine Zuckerpuppe, die Diabetes darstellt, ein Schrei hallt durch den Raum, und es erscheint ein Grabmal: «Du wirst gelöscht und stirbst.» about this event: https://c3voc.de

Wenn ihr beim Anblick des Titels instinktiv vor euch auf den Tisch geschlagen und "Was ist ein beliebtes Abendprogramm auf Chaos-Veranstaltungen?" (oder so ähnlich) gerufen habt, dann habt ihr alles richtig gemacht. Beim Hacker*innen-Jeopardy! müsst ihr schnell sein, wenn ihr die Lösung wisst, und euch auch noch richtig ausdrücken, denn es gilt "Antwort sucht Frage": Die "Antwort" ist hier vorgegeben; eure Aufgabe ist es, einen dazu passenden Fragesatz zu formulieren. Die backspace-Variante des Hacker*innen-Jeopardy! ist euch vielleicht schon von den vergangenen Intergalaktischen Erfahrungsreisen bekannt.

The ongoing digitization of the society and services call for a high availability of secure mobile networks, like 5G. Remote attestation can be a measure to maximize trust, security and privacy when using a mobile telecommunications network. In this talk, I give a rough overview on how a mobile network works, followed by some insight into ongoing threats the public mobile network is facing in the past years. As a solution to some of the threats, remote attestation is a heavily discussed topic in research, and even from the mobile equipment vendors. I give an introduction into the topic of remote attestation and how and where it can be used in mobile networks and how it might impact the performance. about this event: https://cfp.fairydust.reisen/iger-2024/talk/YCWG7K/

Ohne Weltuntergangspropheten zu sein, autarke Kommunikation finden wir schön. Noch schöner, wenn wir auch unter uns bleiben können. Und mit LoRa funken, das ist das i-Tüpfelchen! Über Ge- und Missbrauchsmöglichkeiten sprechen wir in Theorie und Praxis. Was ist ein Node, was macht ein Repeater und was haben Message-Queues damit zu tun? Wie sieht das aus, wenn ich von A nach C eine Nachricht schicken möchte, aber C nicht in Reichweite ist? Könnte ich damit eigentlich auch Sensordaten übertragen? Aufbauend auf Microcontroller-Hardware (ESP32) für lizenzfreien LoRa-Betrieb schauen wir Hard- und Software etwas unter die Haube und probieren aus, ob uns das gefällt. Wer schon ein oder mehrere Boards hat - bitte mitbringen! Einige Boards für 433 MHz haben wir auch vorrätig. about this event: https://cfp.fairydust.reisen/iger-2024/talk/W9PEDM/

Computational Thinking und digitale Handlungskompetenzen kindgerecht vermitteln – FELI an der Uni Bamberg Die Forschungsgruppe Elementarinformatik (FELI) an der Uni Bamberg möchte informatische Konzepte über die Anregung von „Wie funktioniert das?“'-Fragen vermitteln und zudem Lehrkräfte dazu befähigen, dies mit ihren Schülys zu tun. Schon Kinder lernen Computer, Smartphones, das Internet als Konsumentys kennen, als ein Angebot, das sie weitgehend passiv nutzen. Wir wollen ihnen die Fähigkeiten vermitteln, diese Technik als Werkzeug nutzen zu können, ihre Ideen umzusetzen, zu gestalten. Dazu müssen sie verstehen, wie Computer grundsätzlich funktionieren, was ein Algorithmus ist, und wieso der Rechner nicht mit dem Drucker reden kann. about this event: https://cfp.fairydust.reisen/iger-2024/talk/T3VQVG/

Die KI ist da und in der Bildung drehen alle durch. Dabei scheinen die meisten Lehrkräfte und deren Vorgesetzte nicht zu wissen, was ein LLM eigentlich tut.
