Xous: A Pure-Rust Rethink of the Embedded Operating System (en)

bunnie, Sean "xobs" Cross

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.
GPTDash – Der Reverse-Turing-Test (de)

Benny, KI-lian, BratscherBen

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.

Textiles 101: Fast Fiber Transform (en)

octoprog

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 industrial tools.
Reverse engineering the Pixel TitanM2 firmware (en)

willem

The TitanM2 chip has been central to the security of the google pixel series since the Pixel 6. It is based on a modified RISC-V design with a bignum accelerator. Google added some non standard instructions to the RISC-V ISA. This talk investigates the reverse engineering using Ghidra, and simulation of the firmware in python.

Power Cycles statt Burnout – Wie Einflussnahme nicht verpufft (de)

Rahel Becker, Anna Kassautzki

Zwischen offenen Briefen, Massenmails, Petitionen und Kaffee trinken : Zwei Ex-Insiderinnen aus dem Digitalausschuss und Bundestag erzählen, wie politische Einflussnahme wirklich funktioniert. Ein ehrlicher Blick hinter die Kulissen parlamentarischer Entscheidungsfindung – mit praktischen Tipps, wie die Zivilgesellschaft ihre Energie dort einsetzt, wo sie wirklich Wirkung entfaltet.
The Maybe Talent Show (en)

Norman Müller-Schmitz, lukas-schmukas, James Bonne d'age
