erdgeist & monoxyd denken laut. Aufgrund des großen Erfolgs soll das jetzt auch beim Congress versucht werden. Themen? Ja! Wahrscheinlich irgendwas mit so... Dingen, die gerade passiert sind und zu denen mal was gesagt werden muss. Besser wir als Lanz & Precht! Es gibt außerdem einen besonderen Anlass: 23! (Wo kommt das eigentlich her?)

Wer hat Angst vor dem Neutralitätsgebot? (39c3)

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

2025/12/29

Wer überhaupt „neutral“ sein muss, was das bedeutet, und wer sich jetzt wehren muss. „Neutralität“ wird zum neuen Kampfbegriff: Weil sie gegen die menschenfeindliche Politik von Friedrich Merz protestieren, wirft die CDU Gruppen wie Omas gegen Rechts, Greenpeace und Correctiv vor, nicht neutral zu sein. Unter Berufung auf ein angeblich verletztes Neutralitätsgebot werden staatliche Förderungen gestrichen und NGOs geraten unter Beobachtung des Verfassungsschutzes. Julia Klöckner verbietet im Namen

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

Watch Your Kids: Inside a Children's Smartwatch (39c3)

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

2025/12/29

Join us as we hack at a popular children's smartwatch and expose the secrets of every fifth child in Norway, their parents, and millions more. Smartwatches for children have entered the mainstream: Advertised on the subway and sold by your cell provider, manufacturers are charging premium prices comparable to an entry-level Apple watch. In exchange, parents are promised peace of mind: A safe, gentle introduction into the world of technology — and a way to call, text, and locate their child at any

2025/12/29

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. In the late seventies, Motorola created a very cheap CPU, intended to replace logic circuits made from electromechanical relays. The resulting IC is so

2025/12/29

Ich bin ja glaube ich reichlich spät, aber da Moepern endlich wieder zum Congress kommt und ich das erst vor kurzem erfahren habe, dachte ich, ich werfe unseren Namen mal in den Hut. Wir sind/waren ein Biologie-Podcast und durch Babypause bei Moepern ist der etwas eingeschlafen. Schaffen wir ein Revival? Verratet ihr's uns. Wir nehmen auch den Podcast-Tisch wenns sonst nicht passt. :) In der Zellkultur reden Claudia (moepern) und Anna (Adora Belle) über das Leben, die Biologie und den ganzen Rest

2025/12/29

Die Teckids-Gemeinschaft bringt Kinder, Jugendliche und Erwachsene zusammen, um gemeinsam aktiv für eine verstehbare (digitale) Welt zu sein. Bei Teckids geht es nicht "nur" um Technikbasteln und Programmieren mit Kindern, sondern darum, mit anderen, für andere, bei Events und gesellschaftlich aktiv zu werden. In letzter Zeit haben wir viele Projekte dafür unternommen. Unter anderem haben wir den neuen Themen-Slot "Jung und überwacht" bei den BigBrotherAwards 2025 gestaltet und bereiten

What Makes Bike-Sharing Work? (39c3)

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

2025/12/29

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

2025/12/29

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. The Vital Bracelet series, active from 2021 to 2024, was a line of toys that revolved around a number of fitness bracelets that encouraged exercise by raising

2025/12/29

Learn how to find your position using a sextant and a custom slide rule, almost no math required! Since the dawn of time people have asked themselves: where am I and why am I here? This talk won't help you answer the why question, but it will discuss how determine the where in the pre-GPS age of sextants, slide rules and stopwatches by taking the noon sight, aka the meridian passage. The usual way to find your position using the Sun requires a large almanac of lookup tables and some challenging

Hacking Karlsruhe - 10 years later (39c3)

2025/12/29

"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

2025/12/29

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

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

Design for 3D-Printing (39c3)

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

2025/12/29

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

Greenhouse Gas Emission Data (39c3)

2025/12/29

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. Which factory in my city is the largest emitter of CO2? Which industrial sector is responsible for the largest share of a country's contribution to climate change? It should not be difficult to answer these questions. Public

We went on Kleinanzeigen and started a non-profit semiconductor lab. We created a space to do the kind of research we've always wanted, but couldn't do at our local hackerspaces - either due to space constraints, or lack of structures allowing for a safe operation of a proper lab. -- This video was independently recorded & produced by dmi about this event: https://events.ccc.de/congress/2025/hub/en/event/detail/fafo-how-we-stopped-worrying-and-bought-an-electro

KIs (bzw. LLMs) wirken immer menschlicher. Schon längst ist es schwer bis unmöglich zu erkennen, ob ein Text von einer KI oder einem Menschen geschrieben wurde. Maschinen dringen immer mehr in den menschlichen Diskurs ein. Wir wollen das nicht länger hinnehmen und drehen den Spieß um. In unserem Reverse-Turing-Test schlüpfen die Teilnehmenden in die Rolle einer KI und versuchen so robotisch-menschlich wie möglich zu klingen. In einer anschließenden Blindstudie prüfen wir, wer sich am besten unter

The Emergency Alert System (EAS) and its SAME (Specific Area Message Encoding) protocol are public alerting technologies that broadcast short digital bursts over VHF triggering emergency messages on millions of receivers across North America. In Mexico, this technology was integrated into the Seismic Alert System (SASMEX) which more than 30 million people in the central part of the country rely on to prepare for frequent earthquakes. While new alerting technologies have emerged, the EAS-SAME
