In a TED talk, behavioral economist Dan Ariely uses visual illusions and his research to show that people are less rational in their decisions than they think. He covers defaults, such as organ donation rates, and how choice framing steers decisions.

In an 11-minute TED talk, Ralph Langner explains how his team reverse-engineered the Stuxnet worm and worked out that it targeted industrial control systems, with a covert state origin. It is a compact look at cyber-forensics.

Hamish Coleman describes reverse engineering the keyboard controller in a Thinkpad and reflashing it with custom firmware. He covers how Lenovo secures its firmware, and his ongoing work on the protocol between the BIOS and the vendor flash tool.

Neuroscientist Anil Seth argues in this TED talk that perception is a controlled hallucination: the brain constantly predicts the world and our shared agreement is what we call reality. He also touches on the construction of the self.

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.

Seymour Cray's only surviving recorded talk, introducing the Cray-1 supercomputer in 1976. He describes the machine's design, including its vector architecture and cooling through the frame.

Jim Keller's talk at the 2020 Scaled Machine Learning conference on Moore's Law in the age of AI chips. He compares scalar, vector and GPU-style parallel approaches to computation.

Sam Harris argues in a TED talk that we will build superhuman AI and have not grappled with the risk of creating something that may treat us the way we treat ants. He makes a logical case for taking AI risk seriously.

David Ditzel of Esperanto Technologies presents their massively parallel, energy-efficient RISC-V processors at the 7th RISC-V Workshop in 2017. It covers the high-performance many-core design aimed at machine learning.

Noam Chomsky speaks at Google Cambridge in 2017 about his political development and the control of information and media. It is a wide-ranging talk with audience discussion.

An Apple WWDC24 session introducing Embedded Swift, a subset of Swift with no runtime that targets tiny microcontrollers. It demonstrates the idea on an off-the-shelf Matter smart home device.

A Linux.conf.au 2013 talk that explains git's internal model using a playful, toy-based approach. It presents git operations as operations on a graph of commits, aimed at people who find git confusing.

Andrew Adams, a Halide developer, presents the Halide language for image processing and tensor computation. The talk explains the separation of algorithm from schedule with illustrated examples of parallelism, locality and redundancy tradeoffs.

Scott Chacon introduces Git by showing what happens under the hood for basic commands: staging, committing, data storage, branching, merging and pushing. He contrasts it with Subversion and shows history viewing with log.

Retired Major Brian Shul tells the story of a ground speed check with LA Center while flying the SR-71 Blackbird. He recounts it live at the Hiller Aviation Museum.

Edward Kmett's 2013 talk at Prezi in Budapest on succinct data structures, which store data in close to the information-theoretic minimum space while supporting fast queries. It ties together the research and walks through his Haskell succinct library.

Timothy Roscoe of ETH Zurich delivers the joint USENIX ATC/OSDI 2021 keynote arguing that operating systems must reckon with modern hardware, which is a heterogeneous collection of processors, firmware and coprocessors rather than a simple machine. It shows how much runs below and beside Linux.

Deviant Ollam and Howard Payne give an in-depth DEF CON 22 explanation of how elevators work, from the pit to the penthouse. It covers their control modes and how pen testers use elevators to bypass building security.

She explains how opaque algorithms can nudge, segment and manipulate users, and warns that the real danger is powerful people using AI to control populations.
