The web is a mess, bloated with data-gathering trackers, predatory UX, massive resource loads, and it is absorbing everything it touches. The Small Internet is a counter-cultural movement to wrangle things back under control via minimalism, hands-on participation, and good old fashioned conversation. At its heart are technologies like the venerable Gopher protocol or the new Gemini protocol offering a refuge and a place to dream of a better future.

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.

How the history of military and government PSYOPS involving mind-control, UFOs, magic, and remote-control zombies, explains the future of AI and generative media. Along the way, talk attendees will be given an enrollment code to join a specialized CTF/ARG game called CYCLOPS that explores these themes and that will run the duration of Congress.

Variational Autoencoders (VAEs) were first introduced as early concept learners in the vision domain. Since then, they have become a staple tool in generative modeling, representation learning, and unsupervised learning more broadly. Their use as analogues of human cognition is one of the first steps towards the understanding of more complex cognitive models leading up to models of human brain function and behavior. As part of a series of talks on cognitive science and deep learning at the realraum in Graz, this presentation will focus on the role of VAEs in cognitive science research.

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.

As is tradition, between Christmas and New Year the Chaos Communication Congress or C3 for short by the Chaos Computer Club, Germany’s most well known hacker group, takes place. There are lots of talks, workshops and more about a broad range of technology, media and politics.

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.

Zwei Jahre nach dem ersten KIM-Vortrag auf dem 37C3: Die gezeigten Schwachstellen wurden inzwischen geschlossen. Weiterhin können mit dem aktuellen KIM 1.5+ nun große Dateien bis 500 MB übertragen werden, das Signaturhandling wurde für die Nutzenden vereinfacht, indem die Detailinformationen der Signatur nicht mehr einsehbar sind. Aber ist das System jetzt sicher oder gibt es neue Probleme?

Dieser Talk beleuchtet digitalrechtliche Entwicklungen, die das Fediverse betreffen, und diskutiert Forderungen an die Politik.

Aktueller Talk zum Einstieg in den Amateurfunk, nach der Novellierung der Amateurfunkverordnung von Lars Weiler, DC4LW auf dem 38. Chaos Communication Congress.

My talk explores the trajectory of iOS spyware from the initial discovery of Pegasus in 2016 to the latest cases in 2024.

We present fatal security flaws in the HALFLOOP-24 encryption algorithm, which is used by the US military and NATO. HALFLOOP-24 was meant to safeguard the automatic link establishment protocol in high frequency radio, but our research demonstrates that merely two hours of intercepted radio traffic are sufficient to recover the secret key. In the talk, we start with the fundamentals of symmetric key cryptography before going into the details of high frequency radio, HALFLOOP-24, and the foundation of our attack.

Wau Holland war Funkamateur, es gibt die Chaoswelle und auch sonst laufen einem im Chaos immer wieder Wesen über den Weg, die Amateurfunk als Hobby haben. Trotzdem gibt es vielleicht noch Menschen, die die Faszination an diesem rund 100 Jahre alten Hobby besser verstehen wollen.

The talk was made when v5.2 was the latest, with lots of progress since: - local file encryption - desktop client - using mobile from desktop etc.
