A two-hour Oxide and Friends session answering questions after shipping the first Oxide rack. Topics include making hardware as a startup and why Oxide chose illumos.

Dalibor Farny documents the hand manufacture of a nixie tube, from glassblowing to evacuation, with text notes rather than narration. He revived the lost craft of nixie tube making.

A roughly 2.5-hour Toronto debate between Jordan Peterson and Slavoj Zizek on happiness under Marxism versus capitalism. This is the official upload from April 2019.

Lex Fridman interviews economist Richard Wolff, a Marxist, about Marxism, communism, capitalism and worker cooperatives. The conversation runs nearly three hours.

Chris McCord's ElixirConf 2018 keynote introduces Phoenix LiveView, which renders HTML on the server and updates the page over websockets. It includes a demo showing that latency is not the bottleneck one might expect.

Physicist Geoffrey West speaks at an FQXi conference on time about complexity and scaling laws. He covers how metabolism, growth and lifespan scale across organisms and how the same mathematics applies to cities and companies.

The ElixirConf 2019 day 1 morning keynote, including the announcement of Lumen, an alternative BEAM implementation designed for WebAssembly. It features DockYard's team presenting the project and a demo.

Timothy Baldridge presents Pixie, a lightweight Lisp built on RPython, at Strange Loop 2015. It covers C interop, immutable data structures, fast startup and async-by-default IO.

Lex Fridman interviews Marcus Hutter of DeepMind about universal artificial intelligence, AIXI, Kolmogorov complexity, Solomonoff induction and the idea of intelligence as compression.

Ben Krasnow of Applied Science shows that a plain laser diode can measure sub-micron vibrations from centimeters away using self-mixing interferometry, and can also be used for range-finding.

Shaun Lebron surveys 50 years of Lisp editing history and forgotten innovations in structural editing. He argues future Clojure editors could learn from them, and covers ideas like Parinfer.

AutoX shows its fully driverless robotaxi navigating dense, chaotic urban village streets in Chinese cities. The vehicle nudges through crowds, bikes, scooters and pets.

Perry Metzger, an Emacs user since 1983, gives a talk on why he has used one editor for decades. It mixes history, philosophy and speculation about Emacs's future, and teaches some Emacs fundamentals.

Monty Montgomery of Xiph.org gives real-time demonstrations of sampling, quantization, bit depth and dither using real audio equipment, including both digital analysis tools and vintage analog bench gear. It shows that sampled audio is not stair-stepped and corrects common misconceptions about digital audio.

Alain de Botton's 2004 documentary based on his book Status Anxiety, running over two hours. It asks why people in rich societies are still unhappy, and examines how worries about success, snobbery and meritocracy drive that anxiety.

Moxie Marlinspike's DEF CON 18 talk on changing threats to privacy argues that surveillance arrived through convenient services and network effects, so opting out is not a real solution. It also includes his framing of getting social democracy rather than the fascism people feared.

Rich Hickey's Strange Loop 2011 keynote separates 'simple' (not intertwined) from 'easy' (familiar or near at hand) and argues that software complexity comes from complecting things. It offers a vocabulary for judging designs and abstractions.

Chris McCord's ElixirConf EU 2019 keynote introducing Phoenix LiveView, which builds interactive server-rendered apps without writing JavaScript. It explains how only changed dynamic parts are sent over a websocket.

3Blue1Brown explains why plotting primes in polar coordinates produces spiral patterns, using modular arithmetic, Dirichlet's theorem and rational approximations of pi.

Destin Sandlin of Smarter Every Day undergoes hypoxia training and experiences his own impaired thinking as oxygen is withdrawn. The video shows how quickly and unnoticeably oxygen deprivation degrades judgment, illustrating why you put your own mask on first.

Moxie Marlinspike's DEF CON 19 talk on the weaknesses of SSL and the certificate authority system. He explains how CA trust became a problem and proposes an alternative that removes the CA oligopoly without reducing security.

Leonard Susskind lectures at Stanford on how gravity and quantum information theory have merged into a new way of thinking about physics. He covers entanglement and complexity, with applications from black holes to strange metals and the foundations of quantum mechanics.

Moxie Marlinspike's DEF CON 18 talk argues that privacy threats have shifted from centralized state databases like TIA to corporate data collection by companies like Google, despite wins in strong cryptography and decentralization.
