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.

I Hated All The Cross-Stitch Software So I Made My Own: My Deranged Outsider Software Suite For Making Deranged Outsider Art (en)

yomimono

I wanted to design beautiful header diagrams and ASCII tables suitable for stitching on throw pillows, but found existing tools for cross-stitch design to be all wrong. I made my own set of command-line tools for building this chunky, pixelated visual art. If you've never seen a cross-stitch sampler that had bitrot, this talk will fix it.
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.

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.
