A DEFCON 21 talk by Robert Stucke on DNS errors caused by single-bit flips, which lead to requests for misspelled domains. It shows real-world data on bitsquatting.

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.

A 1992 MIT Sloan talk and Q&A by Steve Jobs, then CEO of NeXT, covering NeXT's strategy, co-creating Apple, his ouster, and the value of direct experience. It ranges across technology, business and career advice.

A Talks at Google visit by Douglas Engelbart, inventor of the mouse. He presents his lifelong aim of augmenting collective human intelligence, followed by a Q&A.

Kim Nilsson presents his investigation into how Mt. Gox was hacked and mismanaged, tracing the finances and the missing bitcoins. It was given at the 2017 Breaking Bitcoin meetup.

Ted Nelson's short eulogy for Douglas Engelbart, delivered at the Computer History Museum in 2013, reflecting on his friend and Engelbart's ideas.

Recording of the January 1984 Boston Computer Society meeting where Steve Jobs unveiled the Macintosh. It is followed by a panel Q&A with core Mac team members such as Andy Hertzfeld, Bill Atkinson and Steve Capps.

A HOPE09 talk on how modern computer chips are manufactured, from 22nm transistors to ultra-clean fabs and the tricks used to pattern tiny features with light. It frames chipmaking as hacking electrical engineering and physics.

A short !!Con 2016 talk by blind developer Sina Bahram on how he uses a computer and writes code with a screen reader at about 1,000 words per minute. He plays how common interfaces sound and challenges the audience to go a day using only the keyboard.

Stephen Duneier describes a decision-making approach that took him from struggling with simple tasks to achieving ambitious goals. The talk centers on breaking goals into small marginal adjustments.

Conrad Wolfram argues that the part of math taught in schools, hand calculation, is tedious and mostly irrelevant to real mathematics. He proposes teaching math through computer programming so students can tackle real problems.

Vim author Bram Moolenaar's 2007 Google Tech Talk on habits for efficient text editing: find inefficiencies in your own editing, then learn the Vim commands that fix them.

Alan Kay's 1997 OOPSLA keynote argues that the computer revolution has not really happened yet, reflecting on how computing, objects and the web fall short of their potential.

Adam Grant's TED talk on the habits of original thinkers, including procrastination and embracing failure. He argues the greatest originals fail the most because they try the most.

R. Stanley Williams of HP Labs gives a keynote on the memristor, covering the physics, crossbar computation, and potential for memory and new computer architectures.

Jason Turner's CppCon 2016 talk builds a simple Commodore 64 game using C++17, showing how constexpr and const let a modern compiler produce tight 6502 code. He walks through assembly output to show abstractions being optimized away.

Guy Steele's invited talk at Clojure/conj on the informal metanotation computer scientists use in papers to describe languages. He traces how this notation developed and why it is often unspecified and arcane.

Chuck Moore, inventor of Forth, presents GreenArrays' 144-core asynchronous chip at Strange Loop 2013. He explains how idle cores draw almost no power and how tight code minimizes energy use.

Alan Kay's 1997 OOPSLA keynote, preserved on YouTube after being lost from Google Video. He discusses what object orientation was meant to be, messaging, system design, and the state of computing practice.

A SXSW talk by W Watson that uses Lacanian psychoanalysis, with nods to Zizek, to critique popular programming languages. It argues that people choose and defend languages for emotional and ideological reasons rather than rational ones.

Cliff Click, author of HotSpot's JIT compiler, shares hard-won advice for people writing virtual machines at the VMSS16 workshop. Topics include interpreters, JITs and performance lessons.
