2025/12/28

Join bleeptrack for a deep dive into the fascinating world of procedural generation beyond the screen. From stickers and paper lanterns to PCBs, furniture, and even physical procedural generators, this talk explores the challenges and creative possibilities of bringing generative projects into tangible form. In this talk, I will share practical insights from developing procedural generation tools for physical objects: ranging from stickers and paper lanterns to printed circuit boards and even

2025/12/28

What happens when AI-powered criminals meet AI-powered hunters? A technical arms race where both sides are vibing their way through exploitation—and the backdoors write themselves. In October 2025, we investigated Taiwan's fake delivery scam ecosystem targeting convenience store customers. What started as social engineering on social media became a deep dive into two distinct fraud platforms—both bearing the unmistakable fingerprints of AI-generated code. Their developers left more than just bugs:

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

2025/12/28

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

Milliarden von Kameras produzieren täglich Bilder, die zunehmend von Maschinen analysiert werden. In dieser Lecture Performance beleuchten wir die Entwicklung des maschinellen Sehens – von den frühen algorithmischen Ansätzen bis zu den heutigen Anwendungen – und schauen, wie verschiedene Künstler:innen diese Technologien nutzen und reflektieren. Anhand der beiden Arbeiten „Throwback Environment” und „Fomes Fomentarius Digitalis” betrachten wir die Nutzung des maschinellen Sehens in einem

We pointed a commercial-off-the-shelf satellite dish at the sky and examined all of the geostationary satellite communications visible from our vantage point. A shockingly large amount of sensitive traffic is being broadcast unencrypted, including critical infrastructure, internal corporate and government communications, private citizens’ voice calls and SMS, and consumer Internet traffic from in-flight wifi and mobile networks. In this talk, we will cover our hardware setup, alignment techniques,

Textiles 101: Fast Fiber Transform (39c3)

Chaos Computer Club - recent events feed (high quality) ·

2025/12/28

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

How To Minimize Bugs in Cryptography Code (39c3)

Chaos Computer Club - recent events feed (high quality) ·

2025/12/28

"Don't roll your own crypto" is an often-repeated aphorism. It's good advice -- but then how does any cryptography get made? Writers of cryptography code like myself write code with bugs just like anyone else, so how do we take precautions against our own mistakes? In this talk, I will give a peek into the cryptographer's toolbox of advanced techniques to avoid bugs: targeted testing, model checking, mathematical proof assistants, information-flow analysis, and more. None of these techniques is a

2025/12/28

CSS is a programming language, and you can make games in it. Let's install NoScript and make some together! This talk is about how HTML and CSS can be used to make interactive art and games, without using any JS or server-side code. I'll explain some of the classic Cohost CSS Crimes, how I made [CSS Clicker](https://lyra.horse/css-clicker/), and what's next for the CSS scene. I hope this talk will teach and/or inspire you to make cool stuff of your own! --- *Content notes:* - Slides feature

Was passiert, wenn staatliche Domains auslaufen - und plötzlich jemand anderes sie besitzt? In diesem Vortrag wird berichtet, wie mehrere ehemals offizielle, aber unregistrierte Domains deutscher Bundesministerien und Behörden erworben werden konnten - und welche Datenströme dadurch sichtbar wurden. Über Monate hinweg konnten so DNS-Anfragen aus Netzen des Bundes empfangen werden - ein erhebliches Sicherheitsrisiko. Unter anderem da es so möglich war Accounts zu übernehmen, Validierungen von

This talk explores the internals of Overwatch which make the game work under the hood. The end goal is to democratise development of Overwatch. Being able to host your own servers and modify the game client to your liking should not be up for discussion for a game many people have paid money for. Hey you! Yes you! Do you want to pay for a game which gets forcibly taken away from you after only six years? Do you want to buy lootboxes in order to unlock cosmetics faster in the game you

"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.

The USA is demanding from all 43 countries in the "Visa Waiver Programme" (VWP), which enables visa-free travel, to conclude an "Enhanced Border Security Partnership" (EBSP). This is intended to grant US authorities direct access to police databases in these - mostly European - countries containing fingerprints, facial images and other personal data. Anyone who refuses this forced "border partnership" faces exclusion from the visa-free travel programme. The US demand is unprecedented: even EU

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

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

How to render cloud FPGAs useless (39c3)

Chaos Computer Club - recent events feed (high quality) ·

2025/12/28

While FPGA developers usually try to minimize the power consumption of their designs, we approached the problem from the opposite perspective: what is the maximum power consumption that can be achieved or wasted on an FPGA? Short answer: we found that it’s easy to implement oscillators running at 6 GHz that can theoretically dissipate around 20 kW on a large cloud FPGA when driving the signal to all the available resources. It is interesting to note that this power density is not very far away from
