A BBC Earth clip from The Hunt showing Portia jumping spiders, which leap many times their body length and ambush prey larger than themselves.

An animated Sprouts video presenting Dietrich Bonhoeffer's argument that stupidity is more dangerous than evil, because reason cannot reach stupid people. It frames stupidity as a social and moral phenomenon.

A short 3Blue1Brown primer on exponential and logistic growth, using early COVID-19 case data to show how epidemics grow and eventually level off. It explains why small changes in growth rate make enormous differences in outcomes.

MedCram's Dr. Roger Seheult summarizes a discussion with Dr. Michael Mina on cheap, paper-based at-home COVID-19 antigen tests. It explains why lower sensitivity can still work well for screening infectious people.

Ben Heck modifies a keyboard with magnets, Hall effect sensors and an Xbox controller so the WASD keys give analog control. He walks through the hardware build.

Robert Miles explains the orthogonality thesis: how an agent can be highly intelligent while pursuing goals that seem stupid or alien to humans. He separates intelligence from goals and touches on the stamp-collector example.

Sabine Hossenfelder explains what flat earthers believe and why, arguing that their reasoning is wrong but not stupid. She suggests scientists should take such believers more seriously.

Josh Kaufman's TEDx talk argues that you can reach practical competence in almost any skill with about 20 hours of focused practice, rather than the 10,000 hours often quoted. He describes how becoming a parent led him to rethink how adults learn, and lays out a short method for rapid skill acquisition.

A Last Week Tonight segment on the US opioid epidemic, tracing how prescription painkillers fed addiction and heroin use. It is the first of three episodes the show devoted to the crisis.

A 1991 NeXT promotional video that stages a head-to-head programming contest between a NeXT computer and a Sun workstation. It shows NeXT's interface builder and object-oriented tooling producing an application far faster than traditional UNIX development.

Ben Vallack compares finger movement on a staggered keyboard with an ortholinear grid keyboard, using an Anne Pro 2 and a ZSA Planck EZ. He argues the stagger forces awkward finger motion.

aGameScout explains rolling, the third major NES Tetris playstyle, in which players tap the back of the controller to move pieces faster than hypertapping. It covers how the technique works and where it comes from.

CityNerd explains why traffic congestion grows nonlinearly as more cars use a road network, and why adding road capacity tends not to fix it. It covers the consequences for drivers, bus riders, cyclists and pedestrians, and discusses alternatives such as true bus rapid transit.

CGP Grey explains why European diseases devastated the Americas while few deadly diseases traveled the other way. He ties it to livestock domestication, dense cities, and the ideas of Guns, Germs and Steel.

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.

A roughly 14-minute interview with OpenBSD founder Theo de Raadt at ruBSD 2013. He talks about making painful changes, getting real feedback, mitigation techniques compared to other OSs, and virtualization.

In this TED talk, Lawrence Lessig argues that American politics is corrupted by Congress's dependence on funding from a tiny fraction of citizens. He uses rapid-fire visuals and calls for a bipartisan push to reclaim the Republic.

SethBling uses Super Mario World glitches to inject and run Flappy Bird code on an unmodified SNES, entering it purely with controller inputs. It was the first time a human completed this kind of exploit by hand.

Dick Hardt's fast-paced OSCON keynote on Identity 2.0 and the move toward user-centric digital identity. It is also famous for its rapid-fire, many-slide presentation style.

The first installment of a hobbyist's video diary documenting his build of a giant walking spider-like vehicle. The footage is casual and self-shot, following the early stages of the project.

Clayton Christensen explains disruptive innovation using the steel industry, showing how mini-mills beat incumbents from the low end. He argues disruption is not about stupid or bad management.

A demo of the 8pen, a gesture-based keyboard replacement for touchscreens that lets users enter text by moving around a circle. It is meant for phones, remotes and game controllers and mimics handwriting.

Bill Gates's 2015 TED talk, given after the 2014 Ebola outbreak, argues the world is unprepared for the next fast-spreading epidemic. He calls for scenario planning, vaccine research, and trained health workers, in the way countries prepare for war.

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.

A Kurzgesagt animation on South Korea's record-low fertility rate and rapidly aging population. It explains why a demographic collapse looks hard to reverse and projects the population shrinking sharply by 2060.

Part 3 of WIRED's Future Cities series on Shenzhen. It examines how attitudes toward patents and intellectual property differ from the West, and how shanzhai (copycat) manufacturing created an ecosystem of rapid iteration and distribution.

A demo of Brigade 3 real-time path tracing at 720p controlled with an Xbox controller. Depth of field, field of view, reflections and shadows can be altered live.

Scott Manley explains the nuclear salt water rocket, Robert Zubrin's concept of a rocket fueled by a rapid nuclear reaction in uranium salt dissolved in water. He covers its extraordinary performance and the dangers of managing it.

A Veritasium video touring Relativity Space and explaining why 3D printing whole rockets cuts tooling costs, allows rapid iteration, reduces part count and enables new designs. It includes an interview with Scott Manley on aerospace engineering.

A 2013 research demo of simulated bipedal creatures whose natural gaits are found by optimizing muscle-based controllers, with no motion capture or keyframe animation. It shows physics-based walking and running emerging from musculoskeletal models.

Air traffic audio of a pilot slurring and incoherent while declaring an emergency due to extreme hypoxia, with controllers at Cleveland Center struggling to understand him.

The official music video for Billy Joel's 1989 song We Didn't Start the Fire, a rapid-fire list of historical events.
