Sandi Metz takes an ugly section of conditional code and refactors it into a few simple objects, bridging object-oriented theory and practice. The talk includes her take on the Gilded Rose refactoring kata and the idea that duplication is cheaper than the wrong abstraction.

Richard Feldman's elm-conf talk on designing models so that bugs from impossible application states cannot occur, using Elm's compiler and types. It demonstrates techniques for making invalid states unrepresentable.

The first lecture of Andy Pavlo's CMU 15-445 Intro to Database Systems (Fall 2019), covering course introduction and the relational model.

Jay Parlar's Strange Loop talk shows how model checkers such as Alloy can find complex bugs in a system's design without running or reading any code. He walks through modeling architectures and checking every possible sequence of operations, including a real security bug and a UI feature-interaction bug.

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.

A 2011 remix of over six hours of talks by Kirk Sorensen and other thorium advocates, explaining thorium as a nuclear fuel and the liquid-fluoride thorium reactor (LFTR). It argues LFTRs could produce energy without long-lived transuranic waste.

Strange Parts tours JLCPCB's large PCB factory in Huizhou, China, walking through the printed circuit board manufacturing process step by step. It shows the machinery, quality checks and scale behind cheap prototype boards.

Robert Miles explains reward modelling, in which an AI learns what humans want from their preference comparisons instead of a hand-written reward function. He walks through the 2017 paper on deep reinforcement learning from human preferences.

Simon Brown's Agile on the Beach 2019 talk presents the C4 model, a lightweight approach to diagramming software architecture with a shared vocabulary and simple notation.

A Motherboard documentary episode from Nebraska about farmers and mechanics fighting manufacturers like John Deere over access to the diagnostic software needed to repair modern tractors. It shows how software locks have taken away farmers' traditional self-reliance.

CuriousMarc inspects a newly arrived Teletype Model 19, an early military unit built around a Model 15 keyboard and printer, after an initial rough cleaning. It is the first part of a restoration series and touches on 5-bit Baudot code.

A 41-minute factory tour showing how the BMW i3 electric car is built from start to finish, in the style of a Megafactories documentary. It shows a highly automated production line with carbon-fiber body construction and robots doing most of the work.

A DEF CON 23 talk by Marc Rogers and Kevin Mahaffey walking through the architecture of the Tesla Model S, what Tesla got right and wrong, and how the interconnected systems can be hacked. It also covers the data the car collects.

Dialect coach Erik Singer analyzes how accurate the accents are of 32 well-known actors, including Brad Pitt and Will Smith, in WIRED's breakdown.

Freeman Dyson recounts how Enrico Fermi rejected his team's meson scattering model, noting that it had too many free parameters. It is the source of the quote about fitting an elephant.

A short demo shows how to use the Tesla Model 3's mechanical emergency door release on the front doors as a backup to the electronic release. It notes an on-screen warning that frequent use could damage the door seals.

An animation presenting a non-standard helical or vortex model of the solar system, in which the planets trail the Sun through space instead of orbiting in flat circles. The model is a non-conventional view that the author says differs from standard diagrams.

A 2018 vlog showing how to use the windshield wipers on a Tesla Model 3, including auto mode, manual settings and voice commands. It is labeled outdated.

A run through the 32 factory presets of the Yamaha DX7 FM synthesizer, with timestamps for each patch such as brass, strings, pianos, bass and tubular bells. It is a straight audio demo of the sounds.

A NeXT, Inc. promotional video showing its highly automated factory and the manufacturing of the NeXT Cube, including automated circuit board assembly.

A long documentary-style film on the 1961 SL-1 reactor accident, where a control rod was withdrawn too far and the reactor went prompt-critical. The resulting steam explosion ejected control rods and shield plugs.

A one-minute Tesla clip showing a prototype robotic snake charger that finds a Model S's charge port and plugs itself in.

Sasa Juric explains what makes Erlang and Elixir suited to server-side systems, focusing on the BEAM concurrency model rather than syntax or ecosystem. He demonstrates processes, supervision, and fault tolerance.

Rich Hickey's Clojure/Conj 2018 keynote argues that Maybe/Option types and rigid type signatures are a poor way to model data that changes over time. He builds the case around optionality, schema growth and compatibility, and presents the ideas behind Clojure spec as an alternative.

Rick Reed of WhatsApp explains at Erlang Factory 2014 how the service scaled to billions of messages with a very small engineering team. He covers the FreeBSD and Erlang stack, Mnesia usage, server counts and bottleneck work.
