A short video that reads out comments from the leaked Team Fortress 2 source code to show the frustration of Valve's programmers over time.

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 three-minute excerpt from Kubrick's 2001: A Space Odyssey in which the HAL 9000 computer refuses to open the pod bay doors. It is the famous malfunctioning-AI scene.

Cognitive scientist George Lakoff lectures on how political debates are framed through language and metaphors tied to values, and on the moral worldviews behind progressive and conservative politics. It was given in 2005 at UC San Diego.

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.

A compilation of the 1977 BBC series The Secret War, a documentary on British scientific and technical efforts in WWII, including radar, German navigation beams and V-weapons. It features interviews with people who were there, including Albert Speer.

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.

Deviant Ollam's two-hour conference talk explains how elevators work, from the pit and buffers to the car top, controller logic and access-control features. It shows how this knowledge can be used for optimization and for bypassing building security.

A recording of physicist Albert Bartlett's well-known lecture on the arithmetic of exponential growth, applied to population and energy use. He argues that steady percentage growth in a finite world cannot continue and sneaks up suddenly.

Archaeologist Eric Cline lectures on the Late Bronze Age collapse around 1177 BC, when interconnected Mediterranean empires fell in rapid succession. He discusses the Sea Peoples and the combined causes of the collapse.
