In this 2019 GDC session, Petri Purho of Nolla Games explains the technical side of Noita's physics engine, including scaling a falling-sand simulation to large continuous worlds and adding destructible rigid bodies. It also shows how the emergent physics drives the gameplay.

Dave Ackley demonstrates the Demon Horde Sort, an inherently robust sorting machine running in his Movable Feast Machine simulator. This is the uncut version with all details and side thoughts.

Big Clive does a complete teardown of a lithium phone battery, taking apart the protection circuit, case and the cell itself. He notes it was risky because the cell was not discharged first.

Michael Levin's NeurIPS 2018 talk on bioelectric computation outside the nervous system, showing how cell electrical networks shape development and regeneration. It covers morphological information processing in living tissue.

Tom Scott's long explainer on YouTube's copyright system, Content ID and the DMCA. He argues the platform's system is a workaround for a broader copyright system that does not fit the modern world.

A Technology Connections video on how ground-source (geothermal) heat pumps work and why they hold efficiency in winter. It also covers related heat pump information, and the description notes air-source heat pumps have since improved.

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.

Steve Yegge records himself working in Emacs and shows off about a dozen features in a roughly 45-minute screen capture. It is an informal, enthusiastic tour rather than a structured tutorial.

Fons van der Plas introduces Pluto.jl, a reactive notebook for Julia that tracks references between cells and re-runs affected cells when code changes. The talk was given at JuliaCon 2020.

An Alan Kay talk on programming and scaling, covering theoretical limits of code size, engineering versus tinkering, and biological cells as inspiration for object-oriented design.

David Kipping presents his proposed Terrascope, a telescope that uses Earth's atmosphere as a lens to achieve enormous magnification. He covers the history of telescopes and his path to the idea, plus Sol-scope and Jupiter-scope variants.

A 36-minute animated deep dive from Branch Education into how DRAM works. It shows how memory connects to the CPU and how billions of bits are stored in nanoscale capacitor cells. It also covers why DRAM sits between SSDs and the processor.

Will Wilson explains autonomous testing: using deterministic simulation and fuzzing, building on FoundationDB's approach, to test software continuously. It sets out the ideas behind his later company Antithesis.

Retro Game Mechanics Explained dissects how Atari's Quadrascan vector displays and vector generator hardware drew games like Asteroids and Tempest.

The first lesson of MangoJelly's FreeCAD 0.20 beginner course, covering setup, preferences and navigation. The series teaches fundamentals through complete workflows such as sketching, Part Design and STL export.

Chase Adam, founder of the nonprofit Watsi, speaks at Startup School 2013 about building a nonprofit startup.

Johann Korndorfer's NVScene 2015 talk on building content with signed distance functions. It focuses on patterns that make SDF modelling more structured, arguing that SDFs capture a shape's essence like vector graphics do compared with polygons or voxels.

Gaming Historian recounts how Alexey Pajitnov created Tetris in the Soviet Union and how a fight over publishing rights spanned the West, Mirrorsoft, Nintendo and the Cold War. It runs about an hour with chaptered parts.

Terence Tao and Grant Sanderson of 3Blue1Brown walk through the cosmic distance ladder, showing how humans measured distances from the Earth to the Moon, Sun, planets and beyond. It includes animations and the history behind each step.

Victoria Warmerdam's Oscar-winning Dutch short film in which a woman fails a series of Captcha tests and is plunged into a strange new reality. It is a dark, Black Mirror-like sci-fi comedy.

Karen Sandler's keynote at Linux.conf.au 2012 on the software running inside medical devices such as her own pacemaker-defibrillator. She discusses the difficulty of learning what code runs in life-sustaining devices and why open source matters there.

Part one of Sandia National Labs' first-person documentary on the use control, detonation safety and survivability of US nuclear weapons. It covers nuclear sharing in NATO and how control of use was separated from possession, leading to the always/never problem.

Matthew Cole's Black Hat 2013 talk on operational security failures by CIA operatives. It covers the Abu Omar case and how sloppy tradecraft with cell phones exposed officers through call records and metadata.

Morten Rand-Hendriksen argues that CSS Grid changes web layout, showing how to place content in cells independent of HTML source order and reshape layouts with media queries. It makes the case for using Grid now that browsers support it.

A video essay by Tom Nicholas critiquing Elon Musk's futurism, covering SpaceX's Mars plans, Tesla versus Ford and the idea of a slow cancellation of the future. It asks whom Musk's vision of the future serves.

A Veritasium video on how a feud between Russian mathematicians led to Markov chains and the modern prediction algorithms built on them. It covers the history and the math behind them.
