A 3-minute demo of a tiny IOCCC 2012 winning C program that simulates fluid dynamics in an 80x25 terminal, using any text (including its own source) as input. The video shows the simulation running to Handel's Water Music.

David Kriesel's 31C3 talk, in German, on the discovery that Xerox scanner-copiers silently replace digits and letters in scanned documents. He explains how the bug stayed unnoticed in the wild for years.

A 38C3 talk on how advanced chips are made, centered on EUV lithography and the global supply chain behind it. It covers technical challenges from raw materials to finished chips and the geopolitical weight of semiconductors.

A 33c3 talk by marcan on reverse engineering the PS4 hardware to run Linux with 3D acceleration. It covers how the console differs from a PC and includes a story about tunneling PCIe over RS-232.

David Kriesel's 36C3 talk, in German, analyzes a year of scraped data on every stop of every long-distance train in Germany. It shows how Deutsche Bahn delay statistics hide cancellations and delays.

Joscha Bach's 32C3 talk applies computational theories of mind to questions of meaning, emotion, and love, asking how computation can explain irrational-seeming human experience.

A 32C3 talk dissecting Red Star OS, North Korea's state-built operating system. The speakers explain its internals and how it invades users' privacy, including file watermarking.

A 36C3 talk on the AMD Platform Security Processor, an undocumented ARM core inside AMD CPUs that runs before the main processor. The speakers present their reverse engineering of its internals.

A 36C3 talk that systematically evaluates OpenBSD's exploit mitigations, asking how effective they really are and what they cost in performance, complexity and inspectability. It challenges the project's security marketing.

A 35C3 talk by Privacy International researchers who captured and decrypted traffic between Android apps and Facebook servers. They show many apps send Facebook device and usage data immediately on launch, even for users without Facebook accounts.

Cory Doctorow's 28c3 keynote argues that the copyright wars were just a skirmish and that the real fight will be a war on the general-purpose computer. He explains why locked-down devices, DRM and surveillance tools all depend on removing general computation.

A 27c3 talk on the Linux desktop (GNOME) by Wolfgang Draxinger, repeatedly interrupted and corrected by Lennart Poettering from the audience. The description notes much of the talk's content is disputed.

Michael Steil's 33c3 talk explains essentially everything about the Game Boy: CPU, video hardware, peripherals, and the tricks used by games and demos. It revives the era of counting clock cycles around hardware limits.

Michael Steil and Christian Hessmann's 34C3 talk explaining the Apollo Guidance Computer end to end: hardware design, operating system, and mission software.

Charles Stross's 34C3 talk on how science fiction gets the future wrong. He argues that corporations are slow, human-powered AIs that optimize for profit, and that regulation lags behind accelerating technology.

David Kriesel's 36C3 talk, in an English translation, analyzes a year of scraped Deutsche Bahn data covering every stop of every long-distance train in Germany. It explores delays and how punctuality is actually measured.

A 36C3 talk by Bunnie Huang arguing that open source is necessary but not sufficient for trustworthy hardware, because verifying hardware is destructive and so creates a time-of-check/time-of-use gap. It surveys supply chain security and classes of hardware attacks, and presents the Betrusted approach to narrowing that gap.

Joscha Bach's 35C3 talk offers an AI perspective on the soul, covering perception, mental representation, agency, consciousness and selfhood as things that can arise in a computational system like the brain.

Daniel J. Bernstein and Tanja Lange survey recent highlights in post-quantum cryptography at 35C3, covering the NIST competition, network protocol experiments, and broken candidates.

Netanel Rubin's 31C3 talk chains Perl's syntax quirks into a powerful remote code execution attack, taking down popular Perl-based projects.

A 37C3 talk by Kaspersky researchers on Operation Triangulation, a zero-click iPhone attack that targeted their own colleagues. They describe capturing every stage of the chain, four zero-days and a previously unknown spyware active for years.

Moxie Marlinspike's 36C3 talk examines why distributed and decentralized technology is hard to build into consumer products, from the perspective of developing Signal. It argues that ecosystems move slowly and federation causes problems.

Joanna Rutkowska's 32C3 talk asks whether trustworthy client systems can be built on x86 hardware, and what realistically can be done about the challenges, such as Intel ME.

Tobias Engel's 31C3 talk shows how weaknesses in the SS7 telephone signaling network let companies and attackers locate, track and manipulate phones from anywhere in the world, with precision down to about 50 meters.

A 35C3 talk presenting a proof-of-concept SPI bus hardware implant with capabilities like those alleged in the Bloomberg Supermicro story, plus countermeasures for detecting such modchips.

A 34C3 talk on the security architecture of the Nintendo Switch and the early progress breaking it. It introduces the Switch's custom OS and software stack, with the hackers' reverse-engineering and glitching work.

A 37C3 talk on how a series of Polish electric trains stopped working after servicing by an independent company. The speakers explain how train control systems work and how they reverse-engineered the software lockouts.
