Scott Wlaschin's NDC talk on using statically typed functional programming, F# in particular, to model a business domain. Types are used to represent the domain precisely and to encode business rules so that illegal states cannot be built, with the compiler acting as an instant unit test.

Scott Wlaschin shows how statically typed functional languages, using F# examples, can model a business domain so that invalid states cannot be represented. The type system acts almost like an instant unit test at compile time.

CGP Grey explains why horses could be ridden and why other animals like zebras and bears were never domesticated for war or riding. It is a follow-up on the topic of animal domestication.

Veritasium explores why the number 37 turns up so often, drawing on Tom Magliery's collection of 37 sightings and a poll of about 200,000 people asked to pick a random number. It covers how humans choose numbers and why 37 stands out.

Eben Moglen's re:publica 2012 talk argues that media which spy on and data-mine the public threaten freedom of thought, and that free technology and free culture are needed to protect it.

Karl Sims's 1994 demonstration of evolved virtual creatures: block-bodied creatures whose bodies and controllers are evolved through selection, mutation and recombination to swim, walk and compete.

Kirsten Dirksen tours the underground ferro-cement dome home of Paula and Bill Lishman, the family behind the geese-led flight story. The skylit earth-sheltered house stays warm below the frost line.

Jafar Husain of Netflix explains at React.js Conf 2015 how Netflix runs React-style rendering without the DOM on smart TVs and game consoles. It uses a canvas-like API for performance.

Tom Scott visits Cloudflare's San Francisco office to show the wall of lava lamps whose camera feed is used as a source of entropy for random number generation. It is a short explainer on how this helps secure internet encryption.

A ten-minute explainer from Hypermind on the wisdom of crowds, covering Galton's discovery and the diversity theorem. It argues that collective intelligence comes from diversity, independence and aggregation.

A one-minute clip of Steve Jobs at the D3 conference in 2005 discussing virtual reality. He compares VR headsets to headphones for video, an analogy later applied to Apple's Vision Pro.

A QCon London 2020 talk by Tesla engineers on the architecture of Tesla's Virtual Power Plant. It covers aggregating distributed batteries and solar with vertically integrated hardware and software across cloud and edge.

Dan Bornstein's Google I/O 2008 talk on the internals of Dalvik, the virtual machine that runs Android code. It covers the motivation for its design, the dex format and its register-based interpreter, plus tips for writing code that suits the platform.

A restored 1994 video of Karl Sims' research on evolved virtual creatures, where simulated block creatures are bred through artificial evolution to swim, walk, follow and compete. It is a landmark demonstration of genetic algorithms in physics simulation.
