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 extra filtering rules for specific characteristics of the datasets. I would like to invite you to have a taste together of these silent, anonymous yet upheld estimations and not-guaranteed rationalities in current sociotechnical artifacts, and on for whom these estimations are good-enough, as it will soon be part our technological infrastructures.

The Tegra X2 is an SoC used in devices such as the Magic Leap One, and Tesla's Autopilot 2 & 2.5 promising a secure bootchain. But how secure really is the secure boot? In this talk I go over how I went from a secured Magic Leap One headset, to exploiting the bootloader over USB, to doing fault injection to dump the BootROM, to finding and exploiting an unpatchable vulnerability in the BootROM's USB recovery mode affecting all Tegra X2s.

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 Museum of Care and the David Graeber Institute have experimented with various projects: the survival collection, Visual Assembly, and creating an open space for horizontal knowledge production—something we hope to develop into an actual University.

2025 was a bad year for South Korean mobile network operators. All three operators (SK Telecom, KT, LG U+) were affected by breach in some part of their respective network: HSS of SK Telecom, femtocells of KT. Meanwhile, handling of the breach by each operators and post-mortem analysis of each breaches have stark differences. The technical details and implemented mitigations are often buried under the vague terms, and occasionally got lost in translation to English. In this talk, I will cover the technical aspects of SK Telecom and KT's breach, and how the operators are coping to the breach and what kind of measurements have been performed to secure their network.
