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.

A recording of the TASBot block at Awesome Games Done Quick 2017, where a robot plays games via tool-assisted speedruns, including Super Mario 64 and Portal on an SNES via arbitrary code execution, and ending with a Twitch Plays segment. It showcases console exploits and creative hardware hacking.

Todd Becker's Ancestral Health Symposium talk arguing that myopia is driven by near-work and can be reversed, covering the biology and epidemiology and experimental evidence for reversal by using weaker lenses.

John Oliver's second Last Week Tonight segment on the opioid epidemic, covering the role of large companies in driving it. It touches on Purdue Pharma and the Sackler family.

Dr. Jason Fung lectures on why obesity became an epidemic since the 1970s, arguing insulin and hormones rather than calories drive weight gain. He explains why calorie counting fails and touches on low-carb eating and fasting.

John Carmack live-codes a simple VR application at Oculus Connect 2 using a Racket-based environment for rapid development and deployment on Gear VR.

Aaron Hsu's FnConf18 talk asks whether APL needs a static type system. He argues that APL's expressiveness and rapid iteration already deliver the benefits usually credited to types.
