Greg Young, who coined CQRS, gives an in-depth GOTO 2014 talk on what event sourcing is, when it is valuable and when it is not, along with its trade-offs and common misconceptions.

Neuroscientist Anil Seth gives a Royal Institution lecture on the science of consciousness. He separates conscious level, content and self, and argues that experience arises from the brain's predictive inference.

Matt Parker gives a hands-on Royal Institution talk on how four-dimensional shapes appear in a 3D world, with props like straw frames, Mobius strips and a knitted hat. It is a playful general-audience tour of the fourth dimension.

Daniel Dennett gives a Royal Institution talk toward a unified theory of information, tying together evolution, learning and engineering. He argues that design can arise bottom-up through small steps without a designer.

Technology Connections explains why the superheterodyne radio has its name and how mixing frequencies lets it tune stations well. It walks through the underlying wave phenomena and algebra and why the design solved a hard tuning problem.

A Royal Institution lecture in which Nicholas Humphrey presents his theory of phenomenal consciousness and its evolution. He draws on the book Sentience and discusses evidence for animal sentience.

Wendover Productions explains how UK rail privatization worked and why it failed. It covers the fragmented operator and infrastructure structure and why market forces apply poorly to rail.

Developmental and synthetic biologist Michael Levin speaks at a Harvard Extension student event on bioelectricity, body intelligence and regenerative medicine. He discusses how cell electrical networks guide growth and form.

Peter Zeihan speaks at Iowa Swine Day 2022 on geopolitics, the end of globalization and agriculture. He argues that supply chains, energy and farm inputs are all about to be disrupted.

Philip Wadler's Lambda Days talk on propositions as types, the link between logic and computation that underlies theorem provers and programming language design.

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 1968 NASA film from the US National Archives explaining why the US needed a nuclear rocket and how the engine works. It also shows combined nuclear and chemical stages for a manned Mars mission.

A Burnistoun sketch from BBC Scotland in which two men try to use a voice-recognition elevator that cannot understand their Scottish accents.

A ColdFusion documentary on the Sackler family and Purdue Pharma, tracing their role in the opioid crisis that has killed over 200,000 people.

A one-minute clip from a 2016 Toronto conference in which Geoff Hinton comments on deep learning and radiology. He suggests radiologists should stop being trained because machines would soon read scans better.

A SAAMI-produced training video for firefighters explaining what happens when sporting ammunition burns, including that unchambered cartridges lack the energy to penetrate much. It includes test footage of ammunition in fires.

A YouTuber explores the Chernobyl zone in 2013, takes a gamma spectrum of a hot reactor fuel fragment, and jokes about a radioactive ant bite. It is a hands-on amateur look at radiation in the exclusion zone.

A Harvard lecture demonstration in which five metronomes on a movable board gradually fall into synchronization through coupling. Removing the coupling lets them drift out of step.

Declassified HUD footage of an F-16 whose unconscious pilot is saved by the Automatic Ground Collision Avoidance System. It shows the aircraft pulling out of a dive on its own.

A live performance at AGDQ 2014 in which Super Mario World is made to execute arbitrary injected code, running other games like Pong and Snake on the cartridge. It is done through a TASBot feeding precise controller inputs.

Real air traffic control audio of the Air Astana flight whose flight controls had been wired in reverse by a maintenance error. The pilots struggle to keep control while ATC tries to help.

A short Inside Edition segment on Daniel Kish, a blind man who uses tongue clicks as human sonar to ride a bicycle through city traffic. He explains that he hears the reflections of the sounds off objects.

A DevGAMM talk by Jonathan Blow arguing that civilizations can lose technological capability and that software quality is already deteriorating. He discusses how knowledge fails to transfer between generations.

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.

Emily Shea explains how repetitive strain injury pushed her to program by voice using speech recognition (Talon), and gives a live coding demo. She argues voice-driven development can be pain-free, efficient and enjoyable.

The full 1984 interview with Yuri Bezmenov, a former KGB operative, in which he lays out four stages of ideological subversion. It is a long interview with G. Edward Griffin.

Greg Young's Code on the Beach 2014 talk on CQRS and event sourcing. He argues mature domains are built on facts that occurred rather than current state, and covers the business and technical benefits.
