All Sorted by Machines of Loving Grace? "AI", Cybernetics, and Fascism and how to Intervene (en)

Katika Kühnreich

While the extreme right is on the rise in many countries and climate change is unrolling, a promising future seems to be written: According to Elon Musk, Sam Altman, and some other “tech bros” it is to leave the dying planet to go to space. With the help of something called “A(G)I”. But what kind of future is the one that is promised? And what is the connection between power cycles of tech company owners and people who's believes can be called fascist? As we moved power through data in the hands of very view, it is important to examine what ideas these view have in their heads. This talk will explore the roots of today's tech fascism and its love for tech. From the early thoughts and movements in the US and Europe to Futurism and the Holocaust, organised with Hollerith punching cards. It will dive into the its blooming relationship with cybernetics, and take a look in the future the “tech bros” want to lure us in. This talk will address the often overlooked topic of how and when people get comfy with diving into movements of hate and how to stop a white supremacy future where we will be sorted by machines. And, in taking a look on past movements opposing authoritarianism and will examine mindsets and possibilities of resistance as well as the possibility of restarting everything. Because we have a planet and loved ones to lose. Wear your safety cat-ears, buckle up, it will be a wild, but entertaining ride.
Zentrum für Politische Schönheit: Ein Jahr Adenauer SRP+ und der Walter Lübcke Memorial Park (en)

Stefan Pelzer, Philipp Ruch

Es ist genau ein Jahr her, dass der Adenauer SRP+ in der Halle des 38C3 stand. Damals war er noch eine Baustelle, aber schon bald machte er sich auf den Weg, um Geschichte zu schreiben. Wir nehmen euch mit auf eine Reise: von Blockade über Protest, von Sommerinterviews bis zu Polizeischikanen lassen wir ein Jahr Adenauer SRP+ Revue passieren. Das könnte lustig werden. Außerdem: alles zum Walter Lübcke-Memorial-Park, den wir gerade direkt vor die CDU-Zentrale gebaut haben. Owei owei: Das wird viel für 40 Minuten.
Building hardware - easier than ever - harder than it should be (en)

Kliment

Building electronics has never been easier, cheaper, or more accessible than the last few years. It's also becoming a precious skill in a world where commercially made electronics are the latest victim of enshittification and vibe coding. And yet, while removing technical and financial barriers to building things, we've not come as far as we should have in removing social barriers. The electronics and engineering industry and the cultures around them are hostile to newcomers and self-taught practitioners, for no good reason at all. I've been teaching advanced electronics manufacturing skills to absolute beginners for a decade now, and they've consistently succeeded at acquiring them. I'm here to tell you why it's not as hard as it seems, how to get into it, and why more people who think they can't should try.
Liberating Bluetooth on the ESP32 (en)

Antonio Vázquez Blanco (Antón)

Despite how widely used the ESP32 is, its Bluetooth stack remains closed source. Let’s dive into the low-level workings of a proprietary Bluetooth peripheral. Whether you are interested in reverse engineering, Bluetooth security, or just enjoy poking at undocumented hardware, this talk may inspire you to dig deeper.
Chatkontrolle - Ctrl+Alt+Delete (de)

khaleesi, Markus Reuter

Seit jetzt schon vier Jahren droht aus der EU die Chatkontrolle. In Deutschland ist das Thema nach den Protesten im Oktober aktueller denn je - und sogar Jens Spahn und Rainer Wendt sind plötzlich gegen diese Form der Überwachung. In diesem Vortrag schauen wir zurück und erklären was, vor allem im Hintergrund, passiert ist. Wir nehmen die Position der Bundesregierung genau unter die Lupe und werfen einen Blick auf die Schritte, die auf EU-Ebene vor uns liegen.
Hacking washing machines (en)

Severin von Wnuck-Lipinski, Hajo Noerenberg

Almost everyone has a household appliance at home, whether it's a washing machine, dishwasher, or dryer. Despite their ubiquity, little is publicly documented about how these devices actually work or how their internal components communicate. This talk takes a closer look at proprietary bus systems, hidden diagnostic interfaces, and approaches to cloud-less integration of appliances from two well-known manufacturers into modern home automation systems.
A post-American, enshittification-resistant internet (en)

Cory Doctorow

Trump has staged an unscheduled, midair rapid disassembly of the global system of trade. Ironically, it is this system that prevented all of America's trading partners from disenshittifying their internet: the US trade representative threatened the world with tariffs unless they passed laws that criminalized reverse-engineering and modding. By banning "adversarial interoperability," America handcuffed the world's technologists, banning them from creating the mods, hacks, alt clients, scrapers, and other tools needed to liberate their neighbours from the enshittificatory predations of the ketamine-addled zuckermuskian tyrants of US Big Tech. Well, when life gives you SARS, you make sarsaparilla. The Trump tariffs are here, and it's time to pick the locks on the those handcuffs and set the world's hackers loose on Big Tech. Happy Liberation Day, everyone!
Chaospager - How to construct an Open Pager System for c3 (en)

Max, Julian

In this talk, we will give an introduction into the project (i.e. how it all started at 38c3 and why we are here now), provide an in-depth review of how the development process of our pager worked and what our future goals are. In our introduction, we will talk about the origin and exploration phase of the inital pager idea (i.e. how we went from the idea of bringing POCSAG Pager transmitter to 38c3, over a cable-bound prototype, to a first working pager on a proper PCB). We will also present our plans of connecting our POCSAG transmitter infrastructure to THOT (CERTs own dispatch software). For our in-depth review about the project, we explain how we encountered major reception problems, how we analyzed them at easterhegg22 and conducted experiments there, and why we are opting for a custom HF frontend design instead of an already-made one from chinese vendors. Moreover, we provide an overview of our transmitter devices and give some advice on how to replicate those. Lastly, we will discuss further challenges and what our next goals are. If we are reaching our milestone until 39c3, we will also give a live demo of the system.
Cracking open what makes Apple's Low-Latency WiFi so fast (en)

Henri Jäger

This talk presents Apple's link-layer protocol Low-Latency WiFi and how it achieves its real-time capabilities to enable Continuity features like Sidecar Display and Continuity Camera. We make more kernel logging available on iOS and build a log aggregator that combines and aligns system- and network-level log sources from iOS and macOS.
In-house electronics manufacturing from scratch: How hard can it be? (en)

Augustin Bielefeld, Alexander Willer

Why is electronics manufacturing hard? Can it ever be made easy and more accessible? What will it take to relocate industrial production to Europe? We share with you what we learned when we spent more than 1 year setting up our own production line in our office in Hamburg. Turns out a lot of the difficulties are rarely talked about or hidden behind "manufacturing is high CAPEX". Come and learn with us the nitty gritty details of batch reflow ovens, stencil printing at scale, and how OpenPnP is a key enabler in our process. While we are far from done with this work, we hope to see others replicate it and collectively reclaim the ownership of the means of electronics production.
freiheit.exe - Utopien als Malware (de)

Christiane Mudra

"freiheit.exe“ ist eine Lecture über die ideologischen Rootkits des Silicon Valley. Sie schlägt den Bogen von den italienischen Futuristen zu den heutigen Tech-Feudalisten, vom Akzelerationismus zur Demokratieskepsis der Libertären, von Tolkien zur PayPal-Mafia. Basierend auf den Recherchen zu meinem Theaterstück "freiheit.exe. Utopien als Malware", in dem journalistische Analyse auf performative Darstellung trifft.
Xous: A Pure-Rust Rethink of the Embedded Operating System (en)

bunnie, Sean "xobs" Cross

Xous is a message-passing microkernel implemented in pure Rust, targeting secure embedded applications. This talk covers three novel aspects of the OS: hardware MMU support (and why we had to make our own chip to get this feature), how and why we implemented the Rust standard library in Rust (instead of calling the C standard library, like most other Rust platforms), and how we combine the power of Rust semantics with virtual memory to create safe yet efficient asynchronous messaging primitives. We conclude with a short demo of the OS running on a new chip, the "Baochip-1x", which is an affordable, mostly-open RTL SoC built in 22nm TSMC, configured expressly for running Xous.

Greenhouse Gas Emission Data: Public, difficult to access, and not always correct (en)

Hanno Böck

Data about greenhouse gas emissions, both from countries and individual factories, is often publicly available. However, the data sources are often not as accessible and reliable as they should be. EU emission databases contain obvious flaws, and nobody wants to be responsible.

What Makes Bike-Sharing Work? Insights from 43 Million Kilometers of European Cycling Data (en)

Martin Lellep, Georg Balke, Felix Waldner

Bike- and e-bike-sharing promise sustainable, equitable mobility - but what makes these systems successful? Despite hundreds of cities operating thousands of shared bikes, trip data is rarely public. To address this, we built a geospatial analysis pipeline that reconstructs trip data from publicly accessible system status feeds. Using this method, we gathered **43 million km** of bike-sharing trips across **268 European cities**. Combined with over **100 urban indicators** per city, our analyses reveal how infrastructure, climate, demographics, operations, and politics shape system performance. We uncover surprising insights - such as why some e-bike systems underperform despite strong demand - and highlight how cities can design smarter, fairer mobility. All data and code are open-source, with an interactive demo at bikesharingflowmap.de.

Supplements und Social Media – wenn der Online-Hype zur realen Gesundheitsgefahr wird (de)

Christoph Wiedmer

Nicht zuletzt durch die Werbung in den sozialen Medien werden in Deutschland immer mehr Nahrungsergänzungsmittel verkauft. Einige Influencer bringen sogar ihre eigenen Präparate auf den Markt. Gleichzeitig häufen sich Fälle, in denen die Einnahme von vermeintlich harmlosen „Supplements“ zu Gesundheitsschäden geführt hat. Der Vortrag will daher die Mechanismen hinter dem Supplement-Hype aufzeigen, zudem erklären, warum aktuell ein ausreichender Verbraucherschutz insbesondere im Internet nicht gewährleistet werden kann, wo Handlungsbedarf für die Politik besteht und wie man sich selbst vor fragwürdigen Produkten schützen kann.
Gegenmacht - Best of Informationsfreiheit (de)

Arne Semsrott

Sind mehr Infos wirklich die Lösung? Ob Jens Spahn, Philipp Amthor oder Friedrich Merz - sie alle sagen offen, was sie vorhaben und machen keinen Hehl aus ihren Verbindungen zur Trump-Regierung, zu Milliardären und der fossilen Lobby. Was bringt Transparenz in Zeiten der autoritären Wende?
AI Agent, AI Spy (en)

Udbhav Tiwari, Meredith Whittaker

Agentic AI is the catch-all term for AI-enabled systems that propose to complete more or less complex tasks on their own, without stopping to ask permission or consent. What could go wrong? These systems are being integrated directly into operating systems and applications, like web browsers. This move represents a fundamental paradigm shift, transforming them from relatively neutral resource managers into an active, goal-oriented infrastructure ultimately controlled by the companies that develop these systems, not by users or application developers. Systems like Microsoft's "Recall," which create a comprehensive "photographic memory" of all user activity, are marketed as productivity enhancers, but they function as OS-level surveillance and create significant privacy vulnerabilities. In the case of Recall, we’re talking about a centralized, high-value target for attackers that poses an existential threat to the privacy guarantees of meticulously engineered applications like Signal. This shift also fundamentally undermines personal agency, replacing individual choice and discovery with automated, opaque recommendations that can obscure commercial interests and erode individual autonomy. This talk will review the immediate and serious danger that the rush to shove agents into our devices and digital lives poses to our fundamental right to privacy and our capacity for genuine personal agency. Drawing from Signal's analysis, it moves beyond outlining the problem to also present a "tourniquet" solution: looking at what we need to do *now* to ensure that privacy at the application layer isn’t eliminated, and what the hacker community can do to help. We will outline a path for ensuring developer agency, granular user control, radical transparency, and the role of adversarial research.

Asahi Linux - Porting Linux to Apple Silicon (en)

sven

In this talk, you will learn how Apple Silicon hardware differs from regular laptops or desktops. We'll cover how we reverse engineered the hardware without staring at disassembly but by using a thin hypervisor that traces all MMIO access and then wrote Linux drivers. We'll also talk about how upstreaming to the Linux kernel works and how we've significantly decreased our downstream patches in the past year. As an example, we will use support for the Type-C ports and go into details why these are so complex and required changes across multi subsystems. In the end, we'll briefly talk about M3/M4/M5 and what challenges we will have to overcome to get these supported.
CCC&T - Cosmic ray, the Climate Catastrophe and Trains. (en)

FantasticMisterFux

How can we predict soil moisture by measuring cosmic ray products and what have trains to do with it? Ever wondered how this Dürremonitor works, that you heared about in ther german news? These question and some more I will try to answer while I give an overview of some of the research that is done by the Helmholtz Centre for Environmental Research (UFZ).

The art of text (rendering) (en)

Nicolas Rougier

Typography is the art of arranging type to make written language legible, readable, and appealing when displayed. However, for the neophyte, typography is mostly apprehended as the juxtaposition of characters displayed on the screen while for the expert, typography means typeface, scripts, unicode, glyphs, ascender, descender, tracking, hinting, kerning, shaping, weigth, slant, etc. Typography is actually much more than the mere rendering of glyphs and involves many different concepts. If glyph rendering is an important part of the rendering pipeline, it is nonetheless important to have a basic understanding of typography or there’s a known risk at rendering garbage on screen, as it has been seen many times in games, software and operating systems.
Demystifying Fuzzer Behaviour (en)

Addison

Despite how it's often portrayed in blogs, scientific articles, or corporate test planning, fuzz testing isn't a magic bug printer; just saying "we fuzz our code" says nothing about how _effectively_ it was tested. Yet, how fuzzers and programs interact is deeply mythologised and poorly misunderstood, even by seasoned professionals. This talk analyses a number of recent works and case studies that reveal the relationship between fuzzers, their inputs, and programs to explain _how_ fuzzers work.
Neuroexploitation by Design: Wie Algorithmen in Glücksspielprodukten sich Wirkweisen des Reinforcement Learning und dopaminergen Belohnungssystems zunutze machen (de)

Elke Smith

Die Legalisierung des Online-Glücksspiels in Deutschland im Jahr 2021 und die zunehmende Normalisierung von Glücksspiel und Sportwetten in den Medien haben ein Umfeld geschaffen, in welchem Glücksspielprodukte leichter zugänglich und gesellschaftlich stärker akzeptiert sind als je zuvor. Diese weit verbreitete Exposition birgt erhebliche Risiken für vulnerable Personen, insbesondere da die Grenzen zwischen Spielen und Glücksspiel zunehmend verwischen. Seit einiger Zeit ist beispielsweise ein deutlicher Anstieg von Spielen zu beobachten, die Glücksspiel-ähnliche Items wie Loot-Boxen beinhalten. Komplexe Designmerkmale in elektronischen Glücksspielprodukten, z.B. Glücksspielautomaten und Online-Slots, sind gezielt darauf ausgerichtet, Individuen zu verlängerten Spielsitzungen zu motivieren, um den Umsatz zu maximieren. Während Glücksspiel für viele Menschen eine Form der Unterhaltung darstellt, kann das Spielverhalten bei manchen eskalieren und schwerwiegende Folgen für das Leben der Betroffenen haben. Dieser Vortrag wird Mechanismen in Glücksspielprodukten und Loot Boxen beleuchten und aufzeigen, weshalb diese Merkmale das Suchtpotenzial fördern können. Hierbei spielen Mechanismen des sogenannten Verstärkungslernens (engl. Reinforcement Learning) eine Rolle, die das menschliche Belohnungssystem aktivieren, also dopaminerge Bahnen, welche an der Vorhersage von Belohnungen beteiligt sind. Besonderes Augenmerk liegt auf dem Reinforcement-Learning, einem Framework zur Modellierung von Lernen durch belohnungsbasiertes Feedback, welches sowohl in der Psychologie zur Beschreibung menschlichen Lernens und Entscheidungsverhaltens als auch zur Optimierung von Machine-Learning-Algorithmen eingesetzt wird. Im Vortrag werden auch Ergebnisse aus eigener Forschung am Labor der Universität zu Köln vorgestellt. Ziel ist es, Mechanismen des Glücksspiels zu erklären, sowie das Bewusstsein für potenzielle Schäden für Individuen und die Gesellschaft zu schärfen und die Notwendigkeit von Regulation sowie verantwortungsbewussten Designpraktiken zu diskutieren.
Not an Impasse: Child Safety, Privacy, and Healing Together (en)

Kate Sim

From the EU’s “Chat Control” to the UK’s age verification, there is a growing legislative momentum across jurisdictions to regulate the Internet in the name of protecting children. The monstrosity of child sexual abuse looms large in shaping how policymakers, advocates, and the public understand the problem area of and propose solutions for detecting, reporting, and removing harmful/illegal content. Children’s safety and adults’ privacy are thus pitted against each other, deadlocked into an impasse. As technologists deeply concerned with safety and privacy, where do we go from here?
Handy weg bis zur Ausreise – Wie Cellebrite ins Ausländeramt kam (de)

Chris Köver

Seit Anfang 2024 dürfen Ausländerbehörden Smartphones von ausreisepflichtigen Menschen nicht nur durchsuchen, sondern gleich ganz behalten – „bis zur Ausreise“. Was als geringfügige Änderung im Aufenthaltsgesetz daherkommt, erweist sich als massiver Eingriff in Grundrechte: Menschen verlieren nicht nur die Kontrolle über ihre Daten, sondern auch ihr wichtigstes Kommunikationsmittel – auf unbestimmte Zeit. Hier hört ihr, welche absurden Blüten das treibt. Von Bayern bis NRW haben Bundesländer inzwischen eigene IT-forensische Tools für ihre Behörden angeschafft, um auf den Geräten nach “Indizien” für die Herkunft zu suchen. Sie setzen Methoden ein, wie wir sie sonst aus Ermittlungsverfahren oder von Geheimdiensten kennen – um die Geräte von Menschen zu durchsuchen, die nichts verbrochen haben.
And so it begins - Wie unser Rechtsstaat auf dem Highway Richtung Trumpismus rast – und warum afghanische Kläger*innen für uns die Notbremse ziehen (de)

Eva, Elaha

Wenn die Regierung sich nicht mehr an das eigene Recht gebunden fühlt, markiert das nicht nur einen politischen Spurwechsel, sondern die Auffahrt auf den Highway to Trumpism. Zeit die Notbremse zu ziehen! Normalerweise trifft es in solchen Situationen immer zuerst diejenigen, die sich am wenigsten wehren können. Doch was passiert, wenn genau diese Menschen mit juristischen Werkzeugen bewaffnet werden, um zurückzuschlagen? Anhand von über 100 Klagen afghanischer Schutzsuchender zeigen wir, wie Ministerien das Bundesaufnahmeprogramm sabotieren, Gerichte sie zurückpfeifen – und die Zivilgesellschaft zum letzten Schutzwall des Rechtsstaats wird. Und wir verraten, warum sich Beamte im BAMF vielleicht lieber krankmelden sollten und welche anderen Möglichkeiten sie haben, um nicht straffällig zu werden.
Excuse me, what precise time is It? (en)

Oliver Ettlin

With PTP 1588, AES67, and SMPTE 2110, we can transmit synchronous audio and video with sub-millisecond latency over the asynchronous medium Ethernet. But how do you make hundreds of devices agree on the exact same nanosecond on a medium that was never meant to care about time? Precision Time Protocol (IEEE 1588) tries to do just that. It's the invisible backbone of realtime media standards like AES67 and SMPTE 2110, proprietary technologies such as Dante, and even critical systems powering high-frequency trading, cellular networks, and electric grids.

Hatupangwingwi: The story how Kenyans fought back against intrusive digital identity systems (en)

Mustafa Mahmoud Yousif

The session title is fashioned after the Kenyan movement building rhetoric “Hatupangwingwi” which is Kenyan slang meant as a call to action to counter anti-movement building techniques by the political class and resist infiltration and corruption. This is true for the organisation and movement building towards inclusive identity regimes in Kenya. The session seeks to explore the lessons from Kenya’s journey to digitalization of public services and the uptake of Digital Public infrastructure. It digs deeper on the power of us and how civil society could stop a destructive surveillance driven digitalisation thus protecting millions of Kenyans.
Suing spyware in Europe: news from the front! (en)

Lori Roussey, Celia/Irídia

In 2022, CitizenLab contacted a member of the Spanish non-profit Irídia to tell them that one of their members had likely been hacked with Pegasus spyware. The target, a lawyer, had been spied on by the Spanish government in 2020 because he represented a Catalan politician who was in prison. His phone was infected with Pegasus during the COVID-19 lockdown, on the same day he was having an online meeting with other lawyers working on the case. Irídia and the lawyer (Andreu) decided to take the case to court. A few years later, he met with Data Rights and invited them to join forces and bring in partners from across Europe to increase the impact. This collaboration led to the creation of the PEGA coalition in May 2025. This talk goes over the status of the case and work we have done across Europe to bring spyware use in court.
A space odyssey #2: How to study moon rocks from the Soviet sample return mission Luna 24 (en)

Paul Koetter

It is 1976 and the USA long stopped going to the Moon when a Soviet automatic landing station called Luna 24 descends to the Lunar surface. It touches down on 3.3 Billion year old rock formations at a place no mission has ever gone before. What exactly happened remains a mystery to this day, but the space probe managed to take a 2.3 m long drill core from the Lunar regolith, packaged the sample in a genius way and launched it for its voyage to Earth. Some days later the sample entered earths atmosphere and landed in remote Siberia and ended up in our hands more than 50 Years later. We tell the story of the sample, the people that brought it to Earth and how we analyzed it with the newest methods including µm sized high intensity X-ray beams, 30kV electron beams and LN2 cooled infrared spectrometers.

*Der deutsche Buchmarkt gegen den Rest der Welt oder auch: Enshittification des Buchmarkts und keine API für ein Halleluja* Es gibt unzählige wundervolle Geschichten und das Internet hat über die letzten Jahrzehnte viele großartige Autor*innen hervorgbracht. Doch Verlage haben begrenzte Kapazitäten und sind außerdem zumeist sehr konservativ in ihren Programmen. Die Lösung für beides: Selfpublishing. Neue und gewitzte, genre-übergreifende Bücher an neugierige Lesende zu bringen, könnte so einfach sein; wären da nicht Barsortimente, fehlende APIs und ein insgesamt schreckliches Ökosystem, die Indie-Autor:innen (und alle, die versuchen, auf dem deutschpsprachigen Buchmarkt irgend etwas Innovatives für Indies zu machen) das Leben schwer machen.

Current Drone Wars (en)

Leonard

The character of drone wars has changed. The large, cumbersome long-range drones have been complemented with small and low-budget drones. Moreover, more and more states are developing, deploying and selling them. Ten years ago at least 50 states were developing them. At the top are USA, Israel, Turkey, China, Iran and Russia. Russia's attack on Ukraine has unleashed a drone war unlike any seen before. In short time the Ukraine has build significant drone production capabilities and announcement that it will increase its own production of quadcopters and kamikaze drones to one million units per year. German defense companies and startups are now promoting a “drone wall on NATO's eastern flank.” Moreover, despite their vulnerability to air defenses, large drones are also being further developed. They are intended to accompany next generation fighter jets in swarms. In this talk, past and current developments are discussed. What are the perspectives now?
CPU Entwicklung in Factorio: Vom D-Flip-Flop bis zum eigenen Betriebssystem (de)

PhD (Philipp)

Factorio ist ein Fabriksimulationsspiel mit integriertem Logiksystem. Dies ermöglichte mir den Bau einer CPU, die unter anderem aus einer 5-stufiger Pipeline, einer Forwarding Logikeinheit, Interrupt Handling sowie einem I/O Interface besteht. Über einen selbst geschriebenen Assembler konnte ich ein eigenes Betriebssystem und Programme wie Minesweeper oder Snake integrieren. Der Talk soll euch zeigen, wie sich klassische Computerarchitektur in einem völlig anderen technischen Kontext umsetzen lässt und wo dabei überraschend echte Probleme der CPU-Entwicklung auftreten. Kommt mit auf die Reise: Vom Blick auf den gesamten Computer bis hinunter zu den einzelnen Logikgattern ist es nur eine Mausradbewegung entfernt!

Textiles 101: Fast Fiber Transform (en)

octoprog

Textiles are everywhere, yet few of us know how they’re made. This talk aims to give you an overview over the complete transformation from fiber to finished textile. We'll be exploring fiber properties, spinning, and techniques like weaving, knitting, crochet, braiding, and knotting, followed by finishing methods such as dyeing, printing, and embroidery. You’ll learn why not only fiber but also structure matters, and how to make or hack textiles on your own without relying on fast fashion or industrial tools.
51 Ways to Spell the Image Giraffe: The Hidden Politics of Token Languages in Generative AI (en)

Ting-Chun Liu, Leon-Etienne Kühr

Generative AI models don't operate on human languages – they speak in **tokens**. Tokens are computational fragments that deconstruct language into subword units, stored in large dictionaries. These tokens encode not only language but also political ideologies, corporate interests, and cultural biases even before model training begins. Social media handles like *realdonaldtrump*, brand names like *louisvuitton*, or even *!!!!!!!!!!!!!!!!* exist as single tokens, while other words remain fragmented. Through various artistic and adversarial experiments, we demonstrate that tokenization is a political act that determines what can be represented and how images become computable through language.
Reverse engineering the Pixel TitanM2 firmware (en)

willem

The TitanM2 chip has been central to the security of the google pixel series since the Pixel 6. It is based on a modified RISC-V design with a bignum accelerator. Google added some non standard instructions to the RISC-V ISA. This talk investigates the reverse engineering using Ghidra, and simulation of the firmware in python.
Design for 3D-Printing (en)

rahix

3D-Printers have given us all the unprecedented ability to manufacture mechanical parts with a very low barrier to entry. The only thing between your idea and its physical manifestation is the process of designing the parts. However, this is actually a topic of incredible depth: Design engineering is a whole discipline to itself, built on top of tons and tons of heuristics to produce shapes that are functional, strong, and importantly: well-manufacturable In this talk, I will present the rules for designing well-printable parts and touch on other areas of design considerations so you can learn to create parts that work first try and can be reproduced by others on their 3d-printers easily.
a media-almost-archaeology on data that is too dirty for "AI" (en)

jiawen uffline

when datasets are scaled up to the volume of (partial) internet, together with the idea that scale will average out the noise, large dataset builders came up with a human-not-in-the-loop, cheaper-than-cheap-labor method to clean the datasets: heuristic filtering. Heuristics in this context are basically a set of rules came up by the engineers with their imagination and estimation to work best for their perspective of “cleaning”. Most datasets use heuristics adopted from existing ones, then add some extra filtering rules for specific characteristics of the datasets. I would like to invite you to have a taste together of these silent, anonymous yet upheld estimations and not-guaranteed rationalities in current sociotechnical artifacts, and on for whom these estimations are good-enough, as it will soon be part our technological infrastructures.
Shit for Future: turning human shit into a climate solution (en)

Elena

Humanity has already crossed the point where simply reducing emissions will no longer be enough to keep global warming below 2°C. According to the IPCC (AR6, WGIII), it is now essential to actively remove greenhouse gases from the atmosphere in order to meet global climate targets, maintain net-zero (or even net-negative emissions), and address the burden of historical emissions. At the same time, degraded soils and the climate crisis are a threat to global food security. Two years ago, I presented an overview of different methods available for carbon dioxide removal. Today, I want to show you an example of how CO₂ can be removed from the atmosphere while simultaneously improving the lives of local communities: Human shit. Human shit is a high abundant biomass, contains critical nutrients for global food security, and causes serious health and environmental issues from poor or non-existent treatment outside industrial countries. Converting shit into biochar presents a powerful solution: the process eliminates contaminants, stabilizes and locks away carbon, and can be used to improve agricultural soils. The challenge is that most nutrients in this biochar are not accessible to plants. To overcome this, I mixed human and chicken shit and produced a “Superchar” that releases far more nutrients. It’s not magic, it’s just some chemistry and putting aside your prejudices and disgust. I’ll show you how I did some shit experiments in Hamburg and Guatemala and how you can do it too.

Aber hier Leben? Nein danke! …oder doch? Wie wir der autoritären Zuspitzung begegnen können. (de)

Jaša Hiergeblieben, Polylux, Lisa Zugezogen

Im Osten stehen nächstes Jahr schon wieder Wahlen an und schon wieder sieht alles danach aus, als ob die AfD eine Regierungsbeteiligung bekommen könnte. Ganz konkret: In Sachsen-Anhalt und Mecklenburg-Vorpommern. Nicht nur diese "rosigen" Aussichten, sondern auch aktuelle Bevölkerungsprognosen werfen gar kein günstiges Licht auf die Regionen. Linke Akteur:innen vor Ort kämpfen täglich dagegen an und sie brauchen unsere Solidarität. Wir müssen dem etwas entgegensetzen. Egal ob als Hacker:innen auf dem Congress oder Westdeutsche in (noch) Grünen Gemeinden. Wo kommt das alles her? Wer macht aktuell etwas dagegen und wie können wir dem rechten Sog begegnen?
The Heartbreak Machine: Nazis in the Echo Chamber (de)

Martha Root, Eva Hoffmann, Christian Fuchs

WhiteDate ist eine Plattform weißer Suprematist:innen, die sich an Rassist:innen und Antisemit:innen richtet – und auf veralteter Infrastruktur basiert. Was die 8000 Mitglieder nicht wussten: Einige der Nazis flirteten dieses Jahr mit realistisch wirkenden Chatbots - und verliebten sich sogar in sie. Mit einer Kombination aus automatisierter Konversationsanalyse, Web-Scraping und klassischen OSINT-Methoden verfolgten wir öffentliche Spuren und identifizierten die Personen hinter der Seite. Dieser Vortrag zeigt, wie KI-Personas und investigatives Denken extremistische Netzwerke aufdecken und wie Algorithmen gegen Extremismus eingesetzt werden können.

Ein analoger Überwachungskrimi mit sauberen Städten, lichtscheuen Elementen, queerem Aktivismus, und kollektiver Selbstorganisation; und mit einer Anleitung wie man Beamten Anfang der 80er das Handwerk legen konnte.
Verschlüsselung brechen durch physischen Zugriff - Smartphone Beschlagnahme durch Polizei (de)

Davy Wang, Viktor Schlüter

Eine zwar profane Methode der Überwachung, die Polizeibehörden in Deutschland jedoch hunderttausendfach anwenden, ist das Auslesen von Daten beschlagnahmter Smartphones und Computer. Dazu nutzt die Polizei Sicherheitslücken der Geräte mithilfe forensischer Software von Herstellern wie Cellebrite oder Magnet aus. Die Verfassungsmäßigkeit der Rechtsgrundlagen ist zweifelhaft. Im Vortrag werden anhand aktueller Fälle technische und juristische Hintergründe erörtert.

FeTAp 611 unplugged: Taking a rotary dial phone to the mobile age (en)

Michael Weiner

This project transforms a classic rotary phone into a mobile device. Previous talks have analyzed various aspects of analogue phone technology, such as rotary pulse detection or ringing voltage generation. Now this project helps you get rid of the cable: it equips the classic German FeTAp 611 with battery power and a flyback SMPS based ringing voltage generator - but still maintains the classical look and feel. The talk demonstrates the journey of bridging analog and digital worlds, explaining how careful design connects a vintage phone to today’s mobile environment - in a way that will make your grandparents happy.
Developing New Medicines in the Age of AI and Personalized Medicine (en)

Dennis Özcelik

Did you ever wonder where all the drugs, which you can get at a pharmacy, come from? Who makes them, and how? Well, there is no easy answer, because the process of drug discovery and development is a very complex, expensive, and challenging journey, riddled with many risks and failures. This holds true for all types of drugs, from a simple pill to an mRNA vaccine or a gene therapy. Today, scientists support this process with a variety of AI applications, cutting-edge technologies, automation, and a huge amount of data. But can the race for new medicines and cures succeed only through more technology, or do we need to rethink the entire process? Let’s take a look at how the drug discovery and development process has worked so far, and how this entire process is changing – for better or worse.

What power structures are inherent to the field of computer-generated art? In the year 1965, so 60 years ago, the first three exhibitions of art created with the help of computers took place - in part independently of each other. We want to present the interesting aspects of developments since then and discuss them with Frieder Nake, one of the people who exhibited in those very beginnings and followed those developments with a critical attitude.
Throwing your rights under the Omnibus - how the EU's reform agenda threatens to erase a decade of digital rights (en)

The Eyes of Photon Science: Imaging, Simulation and the Quest to Make the Invisible Visible (en)

MarKuster

Science advances by extending our senses beyond the limits of human perception, pushing the boundaries of what we can observe. In photon science, imaging detectors serve as the eyes of science, translating invisible processes into measurable and analysable data. Behind every image lies a deep understanding of how detectors see, respond and perform. At facilities like the European XFEL, the world's most powerful X-ray free-electron laser located in the Hamburg metropolitan area, imaging detectors capture ultrashort X-ray flashes at MHz frame rates and with high dynamic range. Without these advanced detectors, even the brightest X-ray laser beam would remain invisible. They help to reveal what would otherwise stay hidden, such as the structure of biomolecules, the behaviour of novel materials, and matter under extreme conditions. But how do we know they will perform as expected? And how do we design systems capable of “seeing” the invisible? I will take a closer look how imaging technology in large-scale facilities is simulated and designed to make the invisible visible. From predicting detector performance to evaluating image quality, we look at how performance simulation helps scientists and engineers understand the “eyes” of modern science.
Live, Die, Repeat: The fight against data retention and boundless access to data (en)

Klaus Landefeld

Both within the EU as well as nationally in Germany, there exists a renewed drive to implement data retention, a practice struck down by the ECJ and discontinued in many national legislations. In parallel, cross-border access to stored data has been mandated within the EU as “e-evidence”, and will soon be extended to 90+ countries under the umbrella of the EU cybercrime convention. In principle, all data stored by service providers will be available to law enforcement as part of a criminal investigation. The timing of both initiatives is not coincidental, as access to data naturally relies on the availability of data. The talk will address the state of play on data retention in various legislations, and introduce the practice of cross border access to stored data by law enforcement as well as its shortcomings and threats to privacy and confidentiality.

Lessons from Building an Open-Architecture Secure Element (en)

Jan Pleskac

The talk will be about our experience from building an open-architecture secure element from the ground up. It explains why openness became part of the security model, how it reshaped design and development workflows, and where reality pushed back — through legal constraints, third-party IP, or export controls. It walks through the secure boot chain, attestation model, firmware update flow, integration APIs, and the testing framework built for external inspection. Real examples of security evaluations by independent researchers are presented, showing what was learned from their findings and how those exchanges raised the overall security bar. The goal is to provoke discussion on how open collaboration can make hardware more verifiable, adaptable, auditable and while keeping secure.
Variable Fonts — It Was Never About File Size (en)

Bernd

A brief history of typographic misbehavior or intended and unintended uses of variable fonts. Nine years after the introduction of variable fonts, their most exciting uses have little to do with what variable fonts originally were intended for and their original promise of smaller file sizes. The talk looks at how designers turned a pragmatic font format into a field for experimentation — from animated typography and uniwidth button text to pattern fonts and typographic side effects with unintended aesthetics. Using examples from projects such as TypoLabs, Marjoree, Kario (the variable font that’s used as part of the 39C3 visual identity), and Bronco, we’ll explore how variable fonts evolved from efficiency tools into creative systems — and why the most interesting ideas often emerge when technology is used in unintended ways.

Transkultureller Hack auf die klassische Musikszene – Vortrag und Konzert (de)

Johanna-Leonore Dahlhoff, Peter Klohmann, Alireza Meghrazi Solouklou, Mirweis Neda, Maria Carolina Pardo Reyes, Eduardo Sabella, Sarah Luisa Wurmer, Berivan Canbolat

Das Bridges Kammerorchester hackt die klassische Musikszene, indem es die Regeln des traditionellen Konzertbetriebs aufbricht: Musiker*innen mit und ohne Flucht- und Migrationsbiografie bringen Instrumente wie Oud, Tar, Kamanche oder Daf in die europäische Orchestertradition. Statt überwiegend Werke verstorbener männlicher, europäischer Komponisten zu spielen, komponieren die Mitglieder ihre Musik selbst – ein radikaler Perspektivwechsel hin zu Vielfalt und Selbstbestimmung. Im Vortrag zeigen sie anhand von Hörbeispielen und persönlichen Geschichten, wie diese Hacks entstehen und machen im Anschluss in einem Konzert die musikalische Vielfalt live erlebbar.
Light in the Dark(net) (en)

Tobias Höller

Science is hard and research into the usage of the Tor network is especially so. Since it was designed to counter suveillance, it gathering reliable information is difficult. As a consequence, the studies we do have, have yielded very different results. This talk investigates the root causes of contradicting studies by highlighting how slight changes in methodology or data selection completely change the results and thereby our understanding of what the Darknet is. Whether you consider it the last bastion of freedom or a haven of crime, this talk will tell you where to look and what to ignore in order to confirm your current opinion. And in case you are open to changing it, we have some food for thought for you.
Human microservices at the Dutch Railways: modern architecture, ancient hardware? (en)

Maarten W

The Dutch railways have been operating an increasingly complicated network of trains for over 80 years. The task of overseeing it is far too complex for a single human. As such, a network of specifically scoped humans has been connected. Over time, computers and software have been introduced into the system, but today there is still a significant role for humans. This talk describes the network of "human microservices" that is involved in the Dutch Railways' day to day operation from the eyes of a software developer.

We, the EU, and 1064 Danes decided to look into YouTube: A story about how the EU gave us a law, 1064 Danes gave us their YouTube histories, and reality gave us a headache (en)

David, LK Seiling

We explore what happens when Europe’s ambitious data access laws meet the messy realities of studying major digital platforms. Using YouTube as a central case, we show how the European Union’s efforts to promote transparency through the GDPR, the Digital Services Act (DSA), and the Digital Markets Act (DMA) are reshaping the possibilities and limits of independent platform research. At the heart of the discussion is a paradox: while these laws promise unprecedented access to the data that shape our digital lives, the information researchers and citizens actually receive is often incomplete, inconsistent, and difficult to interpret. In this talk, we take a close look at data donations from over a thousand Danish YouTube users, which at first glance did not reveal neat insights but sprawling file structures filled with cryptic data points. Still, if the work is put in, these digital traces offer glimpses of engagement and attention, and help us understand what users truly encountered or how the platform influenced their experiences. The talk situates this challenge within a broader European context, showing how data access mechanisms are set up in ways that strengthen existing power imbalances. Application processes for research data vary widely, requests are rejected or delayed without clear justification, and the datasets that do arrive frequently lack the granularity required for meaningful analysis. Yet the picture is not purely bleak. Citizens, researchers, and civil society already have multiple legal levers to demand greater transparency and accountability. The fundamental question is no longer whether democratic oversight is possible, but how we can use the tools at hand to make it real.

Endlich maschinenlesbare Urteile! Open access für Juristen (de)

Beata Hubrig, Nuri Khadem-Al-Charieh

Zur Überraschung Vieler sind Juristen Wissenschaftler, die nach wissenschaftlichen Maßstäben arbeiten sollten und ihre Schriftsätze und Urteile auch nach stringenten wissenschaftlichen Kriterien gestalten und untereinander diskutieren sollten. Doch nur in einigen Rechtsgebieten funktioniert dies. Wie jede Wissenschaft ist auch die Rechtswissenschaft nur so gut wie das ihr zugrundeliegende Quellenmaterial – in diesem Fall sind das meist Urteile. Empirische Untersuchungen über diese Daten sind nur möglich, wenn sie der Forschung auch zur Verfügung stehen. Doch wissenschaftliche Arbeit im juristischen Feld ist aktuell nicht wirklich möglich, da die wenigsten Urteile veröffentlicht werden, da sich die Gerichte meist vor der dadurch anfallenden Arbeit scheuen. Wir betrachten, warum dies Grundsätze der Rechtsstaatlichkeit infrage stellt und warum Player aus der Wirtschaft mehr über deutsche Rechtsprechung wissen, als unsere Gerichte – und wie sie das zu Geld machen.

From Silicon to Darude Sand-storm: breaking famous synthesizer DSPs (en)

giulioz

Have you ever wondered how the chips and algorithms that made all those electronic music hits work? Us too! At The Usual Suspects we create open source emulations of famous music hardware, synthesizers and effect units. After releasing some emulations of devices around the Motorola 563xx DSP chip, we made further steps into reverse engineering custom silicon chips to achieve what no one has done before: a real low-level emulation of the JP-8000. This famous synthesizer featured a special "SuperSaw" oscillator algorithm, which defined an entire generation of electronic and trance music. The main obstacle was emulating the 4 custom DSP chips the device used, which ran software written with a completely undocumented instruction set. In this talk I will go through the story of how we overcame that obstacle, using a mixture of automated silicon reverse engineering, probing the chip with an Arduino, statistical analysis of the opcodes and fuzzing. Finally, I will talk about how we made the emulator run in real-time using JIT, and what we found by looking at the SuperSaw code.

selbstverständlich antifaschistisch! Aktuelle Informationen zu den Verfahren im Budapest-Komplex - von family & friends Hamburg (de)

Andreas family & friends Hamburg, Birgit family & friends Hamburg

Mit den Prozessen im Budapest-Komplex wird ein Exempel statuiert - nicht nur gegen Einzelne, sondern gegen antifaschistische Praxis insgesamt. Die Behauptung einer kriminellen Vereinigung mit Mordabsichten stellt eine absurde juristische Eskalation des staatlichen Vorgehens gegen Antifaschist*innen dar und steht in keinem Verhältnis zu den verhandelten Vorkommnissen. Die Verfahren in dieser Weise zu verfolgen, lässt vor allem auf ein hohes Ausforschungs- und Einschüchterungsinteresse schließen. Mit dieser Prozesswelle und den Repressionen gegen Freund*innen und Angehörige wird antifaschistisches Engagement massiv kriminalisiert und ein verzerrtes Bild von politischem Widerstand gezeichnet - während gleichzeitig rechte Gewalt europaweit zunimmt und faschistische Parteien erstarken. Wir sehen, dass Angriffe auf Rechtsstaatlichkeit und Zivilgesellschaft immer weiter zunehmen. Die Art und Weise, wie gegen die Antifas im Budapest-Komplex und im Antifa-Ost Verfahren vorgegangen wird ist ein Vorgeschmack darauf, wie politische Opposition in einer autoritären Zukunft behandelt werden könnte. Wir sind alle von der rechtsautoritären Entwicklung, von Faschisierung betroffen. Die Kriminalisierung von Antifas als "terroristische Vereinigung" ist Teil einer (weltweiten) Entdemokratisierung und Zersetzung von Rechtsstaatlichkeit.
Über europäische Grenzen hinweg auf klinischen Daten rechnen - aber sicher! (de)

Hendrik Ballhausen

Der Trend geht dahin, aus Gesundheitsdaten große zentralisierte Datenbanken aufzubauen. Eine datensparsame Alternative dazu ist, in einem verschlüsseltem Netzwerk gemeinsam auf verteilten privaten Daten zu rechnen, ohne sie miteinander teilen zu müssen. Perspektivisch können so demokratischere Datenströme geschaffen werden, die Patient:innen als aktiv Teilhabende statt als passive Datenquellen einbinden. Kommt mit auf eine Reise, die vor sechs Jahren in Deutschland gestartet ist und jetzt die erste europäische klinische Studie mit Secure Multiparty Computation (SMPC) realisiert hat.
Auf die Dauer hilft nur Power: Herausforderungen für dezentrale Netzwerke aus Sicht der Soziologie (de)

Marco Wähner

Der Vortrag diskutiert Herausforderungen dezentraler Netzwerke aus soziologischer Perspektive. Als dezentrale Netzwerke werden technische Infrastrukturen verstanden, die nicht von einer zentralen Autorität, sondern verteilt über Instanzen zur Verfügung gestellt werden. Nutzer:innen profitieren von dieser Infrastruktur, nutzen beispielsweise das Fediverse oder das Tor-Netzwerk, ohne zur Infrastruktur beizutragen. Zugleich können dezentrale Netzwerke nur dann bestehen, wenn hinreichende Ressourcen von Personen oder Organisationen mobilisiert werden, um das Netzwerk überhaupt zur Verfügung zu stellen. Dies führt zur originären Instabilität dezentraler Netzwerke, wenn nicht der Weg der Kommodifizierung des Nutzer:innenverhaltens eingeschlagen wird. Aufbauend auf dieser Zustandsbeschreibung, werden Bedingungen erörtert, um Kollektivgüter wie dezentrale Netzwerke organisatorisch (und nicht technisch) herzustellen. Hierzu zählen Partizipation oder die Idee einer öffentlichen Grundfinanzierung. Der Vortrag wird neben soziologischen Ideen und harten Zahlen auch durch eine ordentliche Portion Idealismus zu Fragen der Souveränität und Autonomität in der Digitalisierung motiviert.

The Museum of Care: Open-Source Survival Kit Collection (en)

Nika Dubrovsky

The talk is about the ideas behind setting up the David Graeber Institute and the Museum of Care. The Survival Kit Collection brings together collectives developing open source "social technologies" —spirulina farms, self-replicating 3D printers, modular housing, low-cost water systems, and ... art and education. In 2019, together with David Graeber, we held the first workshop about the Museum of Care at CCC to reimagine the relation between freedom, technology and value. Over these 6 years, the Museum of Care and the David Graeber Institute have experimented with various projects: the survival collection, Visual Assembly, and creating an open space for horizontal knowledge production—something we hope to develop into an actual University.
Hacking Karlsruhe - 10 years later (de)

Jürgen Bering, Simone Ruf

"Wir gehen nach Karlsruhe!“ – das klang vor zehn Jahren nach Aufbruch und juristischem Hack. Heute ist klar: Strategische Prozessführung ist kein Sprint, sondern ein zähes, manchmal frustrierendes Dauerprojekt. In diesem Talk ziehen wir Bilanz: Was haben wir mit zivilgesellschaftlichen Verfassungsbeschwerden im Bereich Technologie erreicht – und wo sind wir gescheitert? Welche Fehler würden wir heute vermeiden, welche Wege waren richtig? Und was bedeutet es, wenn das höchste deutsche Gericht zunehmend weniger Lust auf digitalpolitische Grundrechtsfragen zeigt? Ein realistischer Blick hinter die Kulissen strategischer Klagen – und die Frage: Wie hackt man das Rechtssystem im Jahr 2025?
BE Modded: Exploring and hacking the Vital Bracelet ecosystem (en)

cyanic

The Vital Bracelet series is an ecosystem of interactive fitness toys, content on memory chips, and apps that talk via NFC. In this talk, we'll explore the hardware and software of the series, from its obscure CPU architecture, to how it interacts with the outside world, from dumping OTP ROMs and breaking security, to making custom firmware.
When 8 Bits is Overkill: Making Blinkenlights with a 1-bit CPU (en)

girst (Tobi)

Over the last half year I have explored the Motorola mc14500 - a CPU with a true one-bit architecture - and made it simulate Conway's Game of Life. This talk gives a look into how implementing a design for such a simplistic CPU can work, and how it's possible to address 256 LEDs and half a kiloword of memory with just four bits of address space.
Von wegen Eisblumen! Wie man mit Code, Satelliten und Schiffsexpeditionen die bunte Welt des arktischen Phytoplanktons sichtbar macht (de)

Moritz Zeising (er/he)

Die Arktis ist eine Region, in der die Sonne monatelang weg ist, dickes Meereis den Weg versperrt und deshalb Forschungsdaten ziemlich rar sind. Kompliziert also, herauszufinden was im Wasser blüht! Mit einer Kombination aus Satellitenbildern, Expeditionen und Modellsimulationen auf Hochleistungsrechnern versuche ich, das Verborgene sichtbar zu machen: die faszinierende, farbenfrohe Welt des arktischen Phytoplanktons.
The Last of Us - Fighting the EU Surveillance Law Apocalypse (en)

Svea Windwehr, Chloé Berthélémy

The virus of surveillance is spreading across the European Union. In the form of its "ProtectEU" Internal Security Strategy, the European Commission is planning to attack encryption, re-introduce mandatory data retention and strengthen Europol and Frontex, the main agents of its oppressive law enforcement infrastructure. In this talk, we will journey the wastelands of the EU surveillance apocalypse together: We will take a close look at what politicians are planning to undermine our fundamental rights, the technology involved, and the real harms we must fight. From there, we will chart pathways to resistance and collective immunity against a surveillance agenda that requires us to form new alliances and re-think mobilization.
Hegemony Eroding: Excavating Diversity in Latent Space (en)

Karim Hamdi

Hegemony Eroding is an ongoing art project exploring how generative AI reflects and distorts cultural representation. Its name speaks to its core ambition: to bear witness to the slow erosion of Western cultural hegemony by exposing the cracks in which other cultures shine through. This talk will discuss the blurry boundary between legitimate cultural representation and prejudice in AI-generated media and how generative AI can be used as a tool to explore humanity's digital foot print. It is permeated by a critique of purely profit-driven AI development and it's tendency to blunt artistic exploration and expression.
How to keep Open Source open without leaving our communities open to threats (en)

Quintessence

The Four Freedoms (defined ~40 years ago) and the Four Opens (~15 years ago) for Open Source provided canonical definitions for what are the cornerstones of Open Source Software communities today. While the ethos still applies today, the cultural norms that blossomed to put it into practice are from an era with different challenges. To build a better world, we need to both keep and protect the value system of the Four Freedoms and Four Opens. To do that, we need to re-assess our risk and threat models to balance that allows beautiful minds to flourish as well as introduce responsible friction to prevent harm from coming to them.
What You Hack Is What You Mean: 35 Years of Wiring Sense into Text (en)

Torsten Roeder

Encoding isn’t just for machines — it’s how humans shape meaning. This talk traces 35 years of hacking text through the Text Encoding Initiative (TEI), a community-driven, open-source standard for describing the deep structure of texts. We’ll explore how TEI turns literature, research, and even hacker lore into machine-readable, remixable data — and how it enables minimal, sustainable self-publishing without gatekeepers. From alphabets to XML and the Hacker Bible, we’ll look at text as a living system: something we can read, write, and hack together.
Laser Beams & Light Streams: Letting Hackers Go Pew Pew, Building Affordable Light-Based Hardware Security Tooling (en)

Patch, Sam. Beaumont (PANTH13R)

Stored memory in hardware has had a long history of being influenced by light, by design. For instance, as memory is represented by the series of transistors, and their physical state represents 1's and 0's, original EPROM memory could be erased via the utilization of UV light, in preparation for flashing new memory. Naturally, whilst useful, this has proven to be an avenue of opportunity to be leveraged by attackers, allowing them to selectively influence memory via a host of optical/light-based techniques. As chips became more advanced, the usage of opaque resin was used as a "temporary" measure to combat this flaw, by coating chips in a material that would reflect UV. Present day opinions are that laser (or light) based hardware attacks, are something that only nation state actors are capable of doing Currently, sophisticated hardware labs use expensive, high frequency IR beams to penetrate the resin. This project demonstrates that with a limited budget and hacker-and-maker mentality and by leveraging more inexpensive technology alternatives, we implement a tool that does laser fault injection, can detect hardware malware, detect supply chain chip replacements, and delve into the realm of laser logic state imaging.
Battling Obsolescence – Keeping an 80s laser tag system alive (en)

Trikkitt

Keeping old projects working can be an uphill battle. This talk explores how the laser tag system Q-Zar (Quasar in the UK) has been kept alive since the company behind it failed in the 90s. The challenges encountered, the lessons learnt, and how those can be applied to our own future projects to maximise the project lifetime.

No-Input (de)

CooperfrauMelissengeist

Ein geschlossener Kreislauf aus Klang und Störung. Kein Instrument, kein Ursprung, nur das Rauschen, das sich selbst gebiert. Frequenzen kratzen an der Grenze zum Bewusstsein, Feedback wird zum Atem einer Maschine ohne Körper. Aus dem Dunkel des Signals erhebt sich ein sirrendes Mantra — chaotisch, unheilig, autark. Eine Beschwörung der Leere durch elektrische Selbstzerstörung.

Das "tipple radio" ist eine Collage von Singer-Songwriter-Konzert und szenischer Lesung. Es trägt gecoverte und selbstgeschriebene Songs und Medleys von Punk über Hamburger Schule bis Schlager mit Gitarre und Gesang vor und verknüpft die Inhalte der Songs miteinander. Es entsteht ein Geflecht von Musik und Text, dass Aufbrüche in Abgründen aufzeigt und Hoffnung macht sich gegen die Faschisierung in der Gesellschaft zusammen zu schließen.

Von Berlin ins Exil - Lieder der 20er und 30er Jahre (de)

Kurt Tucholsky, Bertolt Brecht, Friedrich Hollaender, Claire Waldoff: Sie alle waren feste Größen des Berliner Kulturlebens. Es war wild, es war queer, es war jüdisch. Dann kamen die Nationalsozialisten an die Macht. Wer anders dachte – und sang! – wurde systematisch aus dem Land getrieben. Wer konnte, flüchtete ins ungewisse Exil.

The 39c3 Drag Show (en)

Keks

Finally a drag show at the chaos! Blinking lights, colorful outfits, and queers everywhere already seems normal at the congress. So how can it be, that all of this did not come together as drag on stage?! It is time for a really awesome, great drag show at the 39c3! And to show right away how divers drag is, a wonderful cast of drag artists of various genders and expressions can spread their queer joy and art for the audience. The show is hosted by Milky Gay, the nerdiest drag king from NRW, who does not only want to throw glitter at the congress incognito this year. And he is bringing an amazing cast with him Bingus Bongus (Drag Queen, Hamburg) Neuro Spicy (Drag King, NRW) Missass Nostalgia (Drag Queen, NRW) and Kaín Mensch (Drag Thing, Hamburg) will bring their queer art to finally merge chaos and drag! Everyone is welcome, we are trying to have as little barriers as possible to come and watch. No blinking lights during the show (no guarantee for the path there and acts before and after), Music Club accessible with mobility aids and wheel chairs (ask assigned angles). Mostly standing room, few seats at the side might not allow for a good view of the show. Content notes for certain parts of the show include death, cancer, violence, fake weapons, and sexual violence, and will be announced in time so people can leave and come back afterwards. Cheering is encouraged, so it might get loud. (more details tba). Please be nice to each other and especially help short people as well as queers to find a spot where they can see enough. Also, as drag is expensive, there will be a tipping round in the end - please bring some cash if you consider tipping the artists, but of course you are also welcome either way.

The Uncontrolled Manifold : dancing with sympoetic machines (de)

Christian Faubel

The Uncontrolled Manifold works with electronics and machines that possess autonomy and obstinacy. These machines are brought into interaction with each other, creating danceable polyrhythms and, at the same time, a fascinating shadow play, because the machines are mounted on an overhead projector and their interaction is projected. Analog oscillators generate self-organizing coordination dynamics and organic patterns, while motors strike rubber strings producing deep, resonant bass sounds reminiscent of shamanic drumming. Supported by the visuals spectators may feel like being dragged into the vortex of a living clock, compelled to join the performance through movement and dance.

Operating in a mode of Kluster via Pole, Dub Syndicate at Conny Plank's, or even fang-baring flashes of The Bug and Bryn Jones or Peak Oil modernism, the trio approach the project from the more oblique angles of respective projects Datashock, Phantom Horse and Love-Songs, to probe a more soft-centred, dematerialised and heady sound, but also reserve the right to go tuffer, more venomous, when they feel it.
