One of the central theses of Jalka's work is t hat a viable democracy and a conscious culture of constructive conflict re solution go hand in hand.\n\nCultivating this ability requires a conscious decision to engage with individual\, collective and societal patterns of dispute behaviour and conflict management. Starting with oneself\, as well as in our interactions with others\, in public discourse and in our behav iour towards others. With a willingness to change something in order to re duce\, and in the best case even prevent\, the suffering and violence that can potentially arise from conflicts. And to learn from this for the futu re.\n\nWhat exactly will this SOS session be about?\n\nWe will engage in a number of exercises and discussion rounds based on the following question s:\n\nHow do you deal with conflicts? How do others deal with conflicts? H ow do you experience conflicts? What exactly are conflicts? What dynamics promote conflicts? What patterns are there in place? How can we deal with conflicts constructively? How do conflicts caused by individual\, interper sonal and structural factors differ? And: How can conflict management be d esigned to be sensitive to discrimination?\n\nI will share with you my exp eriences from my work as a mediator and from past workshops I have held on this topic. In addition to exercises\, I will also bring along some liter ature for further reading.\n\nPlease feel free to bring your own questions and insights to the session so that we can all learn from and with each o ther.

Alongside their vast potential\, these models also present unique security challenges. This session will serve as a primer on LLM security and secure LLMOps\, introducing key issues and concepts rela ted to the security of LLMs and systems relying on them. For example\, we will be looking at issues such as prompt injection\, sensitive information disclosure\, and issues related to the interaction of LLMs with the “ou tside world” (e.g.\, plugins or APIs\, RAG\, Agentic AI). Of course\, we are also going to briefly look at how to red-team LLMs.\n\nThis session i s based on previous iterations of “A Primer on LLM Security” at Congre ss and\, based on audience feedback\, has been extended and developed furt her.\n\n\nThis session is based on previous iterations of “A Primer on L LM Security” at Congress and\, based on audience feedback\, has been ext ended and developed further.\n\n## Target Audience and Required Previous K nowledge\n\nThis session targets beginners and does not assume (in-depth) knowledge about LLMs. If you have prior experience in LLM security and ant icipate insights into the latest developments\, this session most likely i s not for you.\nPlease note that this session will not be about using LLMs in offensive or defensive cybersecurity.\n\n## Learning Objectives\n\nFro m a learning perspective\, after the session\, participants will be able t o …\n\n* describe what LLMs are and how they fundamentally function.\n* describe LLMOps and outline fundamental principles of secure LLMOps.\n* de scribe common security issues related to LLMs and systems relying on LLMs. \n* describe what LLM red teaming is.\n* perform some basic attacks agains t LLMs to test them for common issues.\n\n## About Me\n\nMy Name is Ingo\, and I am currently responsible for Digital Education and Educational Tech nology at the University of Cologne. Relevant to this session\, I have a b ackground in computational linguistics and have been working with LLMs for quite some time – also prior to the ChatGPT moment. I am also involved in developing and providing AI infrastructure at scale. Of course\, all of this is embedded within a deep interest in cyber- and information securit y.\n\n## Format\nThe session will be split into a 45-minute talk as well a s 15 minutes of discussion. Participants will be provided with the slides as well as some resources for further study.\n\n## Technical Requirements \nAs this will not be a highly hands-on session\, there are no technical r equirements. If you want to experiment with some of the topics\, a device capable of accessing and/or running LLMs is necessary. If you want to “g o deeper\,” you will need a device – e.g.\, a laptop\, capable of runn ing LLMs locally.\n\n## Material\n\nAfter the session\, I will provide all materials\, including some selected additional resources. All materials w ill also be provided via this page.\n\n[Slides (PDF) via Slideshare](https ://de.slideshare.net/secret/1UNWblpgKTSoSR)\n\nPs. This is a slightly upda ted version of the workshop(s) I gave at previous iterations of Congress. \n LOCATION:SoS Lecture E URL:https://hub.test.c3voc.de/en/event/detail/a-primer-on-llm-security END:VEVENT BEGIN:VEVENT SUMMARY:Teamtype – multiplayer mode for your text editor!

And if you open a file in your text editor\, you can edit it together\, an d see each other's cursors.\n\nThis enables a new form of smooth real-time collaboration. You can use it for pair programming or note-taking\, for e xample\, all from the comfort of your own editor! It feels a bit like the missing real-time complement to Git.\n\nTeamtype follows local-first princ iples\, and uses encrypted peer-to-peer connections (you don't need a serv er or an account). You can also work on entire projects\, not just single files.\n\nAt 39C3\, it's time for a live demo! Let me show you how Teamtyp e works and what you can do with it! We're maintaining plugins for Neovim and VS Code/Codium\; others are working on plugins for Jetbrains IDEs\, ha ve integrated it into TeXstudio\, or are building a web editor for it! I c an also show you some more experimental features like a Hedgedoc bridge\, or writing commit messages together.\n\nWe'd be excited for more collabora tion on collaboration\, so let me show you how to get involved!\n\nIn the final part of this session\, you can install & try Teamtype for yourself i n a frantic massively-multiplayer editing experiment! :D\n\n- Source code: \n- Documentation: \n- Mastodon: \n LOCATION:SoS Lecture E URL:https://hub.test.c3voc.de/en/event/detail/teamtype-multiplayer-mode-fo r-your-text-editor END:VEVENT BEGIN:VEVENT SUMMARY:Elektronische Patientenakte (ePA) - 13 Fragen\, ob die ePA eine gu te Idee ist DTSTART:20251228T120000Z DTEND:20251228T122500Z UID:79d28d9d-2051-49bd-bc8b-cd9065b70e06 CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/elektr onische-patientenakte-13-fragen-ob-die-epa-e\n\nDescription:\nWir stellen 13 Fragen dazu\, ob die elektronische Patienenakte (ePA) in der vorliegend en Form eine gute Idee ist.\n\nAußerdem zeigen wir Möglichkeiten zum Wid erspruch gegen die ePA: Man kann bei der Assembly von Freedom not Fear ein en Widerspruch erstellen und gleich abschicken.\n\nQ&A findet an der Assem bly von Freedom not Fear statt\, Uhrzeiten werden noch bekanntgegeben.\n LOCATION:SoS Lecture E URL:https://hub.test.c3voc.de/en/event/detail/elektronische-patientenakte- 13-fragen-ob-die-epa-e END:VEVENT BEGIN:VEVENT SUMMARY:Hacking Fusion: better Hot-Fusion Technologies that you have not h eard about DTSTART:20251228T123000Z DTEND:20251228T132000Z UID:48cc8b77-47ac-42f3-a851-0070c245e097 CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/fusion -geht-besser-andere-hot-fusion-technologien-\n\nDescription:\nFusion is al ways 30 years in the future because government projects are too big\, too expensive\, and too slow. It doesn't have to be this way.\n\nThere are bet ter approaches than the three known research directions. There are better fusion fuels that don't cause radioactive contamination. Fusion has even b een achieved by school classes and private individuals. A proof that it is possible with much less effort.\n\nIf we invested as much money in proton -boron fusion as we do in deuterium-tritium\, we would probably have power plants in 15 years. Dense Plasma Focus is suitable for decentralized 10-M W power plants. Inertial Electrostatic Confinement for neighborhood power plants with 100 MW. This is not about cold fusion. It's about fusing atomi c nuclei with high energy (hot) to gain even more energy. But in different physical configurations. Unfortunately\, the media ignores these other ho t fusion approaches.\n\nThis is an info dump on the state of the art: what fusion fuels exist\, how you build your own fusion reactor\, why hot plas ma is physically unfavorable\, why some people want to strip-mine the moon \, and why other fusion projects that must make do with 100 times less mon ey still achieve similar performance. These projects don't appear in the m ainstream press. But they will soon overtake ITER.\n\n\nIf we want to achi eve the energy transition\, then policymakers must stop investing in suppo sedly safe large-scale technology. It could be much faster and cheaper and the new energy grid could be decentralized.\n LOCATION:SoS Lecture E URL:https://hub.test.c3voc.de/en/event/detail/fusion-geht-besser-andere-ho t-fusion-technologien- END:VEVENT BEGIN:VEVENT SUMMARY:Privacy Ultras Meetup DTSTART:20251228T133000Z DTEND:20251228T145000Z UID:92fda60e-ee15-43f7-9f16-3069adb50756 CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/privac y-ultras-meetup\n\nDescription:\nIf you're trying to raise your privacy / OPSEC in the real and digital worlds to a maximum\, this is for you.\n\nTh is is a round-table skill sharing session about practical privacy.\nLet's discuss our threat levels (what we're trying to protect against) and share our approaches to preserving our privacy.\n\nTopics may include how to av oid unique identifiers like your legal or birth name\, phone numbers\, ema il addresses\, physical (postal) addresses\, device identifiers like brows er cookies\, IP addresses\, MAC addresses\, anonymous/multiple SIM cards o r virtual phone numbers\, and all kinds of fingerprinting techniques.\n\nI will bring a list of topics/threats and we'll discuss our solutions to th em.

This session will start off by defining Relationship Anarchy. It will then nest this definition in the context of our current situation (socially\, politically\, technologically). Finally\, we will lo ok at technologies in a wider sense and investigate whether they are nurtu ring or hostile towards the prefiguration of Relationship Anarchy.\n\nDesc ription: Relationship Anarchy is a form of livable anarchy. It follows in the steps of anarchy\, in that it rejects illegitimate authority and nurtu res personal and collective autonomy and agency. Livable anarchy opens up the public space for folx to participate actively in shaping how they wish to live and self-represent their desire and identity. It is rooted in sol idarity and a respectful attitude towards otherness.\n\nIn this talk\, we explore the ways in which technology shapes our ability to practice Relati onship Anarchy\, as a form of livable anarchy. We start off by acknowledgi ng that our use of technology shapes what we can do\, perceive and imagine . In this sense\, we can categorize technologies\, in a broad sense\, as e ither hostile towards Relationship Anarchy\, or as nurturing towards it.\n \nThe basis of this discussion is going to be a definition of Relationship Anarchy that catileptic\, the speaker\, offers in their writing: "Relatio nship Anarchy is honoring alterity while making one's self subject to othe rs".\n\nThis presentation is loosely based on this essay: https://catilept ic.tech/posts/relationship-anarchy-technology/ .\n LOCATION:SoS Lecture E URL:https://hub.test.c3voc.de/en/event/detail/relationship-anarchy-and-tec hnologies-of-conn_x57l END:VEVENT BEGIN:VEVENT SUMMARY:Introduction to Embedded Rust for beginners (for Hakkaa-Board work shop) DTSTART:20251229T120000Z DTEND:20251229T132000Z UID:caef9e32-8b3b-4e91-9710-6b7f2ecf6079 CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/einfuh rung-embedded-rust-fur-workshop-hakkaa-_mlyg\n\nDescription:\n_Introductio n to Embedded Rust on Microcontrollers and the [Hakkaa workshop task](http s://events.ccc.de/congress/2025/hub/en/project/detail/assembly/hakkaa-boar d-smd-soldering-embedded-rust-for-begin/).

This workshop is intended as a first introduction to (Python) programming for absolute beginners. While C3 is t raditionally a 'tech/hacker conference'\, more and more people without a p rogramming background attend – as far as I'm concerned\, this is awesome !\n\nWhile you certainly don't have to be a 'coder' to be a part of Congre ss (or to be a hacker)\, programming is still fun\, wonderfully creative\, and also an extremely valuable skill. Don't be afraid to give it a go!\n \nOf course\, by the end of this 90-minute workshop\, you will not be a pr ogrammer. You will\, however\, have attempted a deep dive into (Python) pr ogramming\, learned some basics\, and set yourself up for further learning (if you choose to do so). Furthermore\, we will explore why it is still w orthwhile to learn programming in a world that is seeing increased LLM usa ge – especially in the domain of software development.\n\n## Target Audi ence and Required Previous Knowledge\n\nThis is NOT a session for experien ced developers who want to learn Python. This session is intended for begi nners with little to no experience programming! Motivated children and you ng hackers are more than welcome\, but it will be a stretch.\n\nNo previou s knowledge and/or technical expertise is required!\n\n## Learning Objecti ves\n\nFrom a learning perspective\, after the session\, participants will be able to …\n\n* describe what programming essentially is about.\n* na me and describe some basic programming terminology.\n* define requirements and design simple software.\n* model simple problems in terms of data str uctures and basic algorithms.\n* write basic scripts in Python in order to solve specific problems.\n* describe the role of LLMs in modern software development.\n\n## About Me\n\nMy Name is Ingo\, and I am currently respon sible for Digital Education and Educational Technology at the University o f Cologne. Relevant to this session\, I have a background in both educatio n and computational linguistics. My love for Python stems from my work as a (computational) linguist and various projects I've been involved with. : )\n\n## Format\n\nThis session will be a 90-minute “code-along” worksh op. We will be looking at some fundamental concepts in theory and\, togeth er\, write some code.\n\n## Technical Requirements\n\nIf you want to parti cipate actively (i.e.\, code along)\, you should bring a device that is ca pable of running a modern browser and has Internet access. Being able to t ype comfortably is also recommended \;). Alternatively\, any device capabl e of running Python 3.10+ (ideally in a Jupyter Notebook) will do just fin e!\n\n## Material\n\nAfter the session\, I will provide all materials\, in cluding some selected additional resources. All materials will also be pro vided via this page.\n\nThe material\, including the slides\, is available via [GitHub](https://github.com/IngoKl/39c3-python-programming-for-absolu te-beginners).\n\nPs.

Wie sind sie früher entstanden? Wird alles immer größer\, oder auch e inmal kleiner und effizienter? Wie entwickeln sich Gesellschaften und Konf likte? Welche wirtschaftlichen und infrastrukturellen Voraussetzungen brau cht es\, um kilometergroße Battleships zu bauen? Wie viele Menschen passe n eigentlich auf die Erde?
