null object

A one-minute clip from Richard Feynman's 1979 Auckland lecture in which he answers whether you see an object or only its light. It is a short, playful take on perception and on the use of philosophy.

Misko Hevery's Clean Code Talk shows how to use object-oriented techniques such as polymorphism to remove repeated if and switch statements. The result is code that is easier to test, understand and maintain.

Steve Jobs demos NeXTSTEP Release 3, showing the object-oriented development environment and UI that later became the basis of Mac OS X. Midway through he builds a database-backed GUI app with Interface Builder and Enterprise Objects Framework with almost no code.

A three-minute demo of ProFORMA, a system from Cambridge that builds textured 3D models live from a video of an object.

Peter Seibel's 2006 Google TechTalk on Practical Common Lisp, framed by the Sapir-Whorf hypothesis and Paul Graham's Blub paradox. It shows Lisp features such as condition restarts and its generic-function object system.

Earliest known footage of Ivan Sutherland's MIT PhD work, Sketchpad, the first computer graphics system, with commentary by Alan Kay. It shows light-pen drawing with constraints in a short clip.

Geoff Cumming uses a simulation to show how wildly the p value varies from one replication to the next because of sampling variability. He argues for estimation and confidence intervals over null hypothesis significance testing.

Sean Parent of Adobe argues that object-oriented frameworks ultimately fail to deliver scalable, high quality software and proposes combining generic and declarative programming instead. It draws on Stepanov's Elements of Programming.

A 2008 CES demo of the original Microsoft Surface, a smart table with multi-touch interaction. It shows touch manipulation of photos and objects on a tabletop display.

A Spike Jonze-directed Ikea commercial in which a discarded lamp is treated sympathetically, until a twist undercuts the sentiment. It is a short, well-known piece of advertising.

A short clip of a Garry Kasparov press conference interrupted by a flying object in a prank. It is a brief, crude stunt video.
