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.

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.

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.

Cuong Do of YouTube describes how a handful of engineers scaled the site, covering hardware, software and database scalability challenges during its rapid growth. The talk was given at the 2007 Seattle Conference on Scalability.

A short demo of typing on the Modos Paper Monitor, an open e-ink monitor, using 4-level grayscale to show low latency.

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.

A demo of the Bad Apple music video played back at 60 FPS on an e-ink display, up from 2.4 FPS in an earlier attempt. It is part of the effort behind the open source Modos e-ink monitor.
