A one-minute clip from The Matrix in which the crew eat a bland nutrient slurry for breakfast and Mouse muses about Tasty Wheat.

Stuart Marks explains the intended purpose and proper use of Java 8's Optional class and why it caused so much controversy. He gives guidelines for using its small API correctly.

A Technology Connections video essay arguing that algorithmic feeds make people passive about finding content, leading to complacency in how they seek information. It urges people to actively choose what they consume.

Brian Springer's documentary Spin, built entirely from unauthorized satellite feeds of politicians and newscasters before they went on air during the 1992 US presidential election. It exposes the behind-the-scenes construction of media reality.

Mark Rober builds a hot tub filled with sand fluidized by air blown from below, so that the sand behaves like a liquid. He explains how fluidized beds work and shows people swimming in them.

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.

Asianometry explains the EUV light source inside ASML's lithography machines, where lasers hit falling tin droplets twice to produce 13.5 nm light. It walks through the engineering of the droplet generator, the pre-pulse and main laser, and the plasma that results.

Lex Fridman interviews legendary chip architect Jim Keller about Moore's Law, microprocessor design, and first-principles thinking. Keller draws on his work at AMD, Apple, Tesla and Intel, discussing instruction sets, transistor budgets, and self-driving.

Jim Keller gives a UC Berkeley EECS colloquium arguing that Moore's Law is not dead. He surveys upcoming technologies and the multiple innovation curves that can keep transistor density and performance scaling.

Veritasium tells the story of how Shuji Nakamura and others made the blue LED, long thought nearly impossible. It covers the materials challenge of gallium nitride and the persistence it took.

A 38C3 talk on how advanced chips are made, centered on EUV lithography and the global supply chain behind it. It covers technical challenges from raw materials to finished chips and the geopolitical weight of semiconductors.

BobbyBroccoli's first of three parts on Jan Hendrik Schon, the Bell Labs postdoc whose fabricated organic semiconductor results nearly won a Nobel Prize. It covers his rise and the context around Bell Labs.

James Hamilton's Tuesday Night Live keynote at AWS re:Invent 2016, touring AWS infrastructure at scale including networking, power and custom silicon. It also features NASA JPL's Tom Soderstrom.
