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).

Atoms in Space (en)

manuel

*What are atoms doing in space anyways?* This talk will provide a brief overview of applications of quantum technologies in space ranging from precise timing and inertial measurements to fundamental physics.
CUII: Wie Konzerne heimlich Webseiten in Deutschland sperren (de)

Lina Lastname, Northernside

Stellt euch vor, eine private Organisation aus milliardenschweren Konzernen entscheidet, welche Webseiten ihr nicht besuchen dürft - ohne Richter, ohne öffentliche Kontrolle oder Transparenz. Genau das macht die CUII in Deutschland seit Jahren.
Who runs the www? WSIS+20 and the future of Internet governance (en)

Sophia Longwe

Abbreviations such as WSIS+20, IGF, IETF, DIEM, ICANN, PDP, ITU or W3C regularly appear in discussions about the Internet, yet often remain vague. This talk provides an update on the current state of Internet governance and explains why decisions made in United Nations processes have direct implications for technical standards, digital infrastructure, and power asymmetries.

Fossile Industrie liebt KI! (de)

Rike, Moritz Leiner

Der Hype um generative KI und die Gasindustrie bilden in Zeiten der Klimakrise eine bedrohliche Allianz für die Zukunft des Planeten.

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.
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.
