type system

A one-minute clip of the Jurassic Park scene where a girl navigates the FSN 3D file manager on an SGI system and declares it a Unix system.

Coast Guard footage of a Cirrus SR-22 pilot who ran out of fuel over the Pacific and deployed the airframe parachute, then escaped into a life raft. It shows the Cirrus Airframe Parachute System working in a real emergency.

A spoof commercial by the Groen Brothers for a Star Wars-style laser defense system against mosquitoes.

A short screen capture of SGI's File System Navigator (FSN, also called Fusion) running on IRIX 6.5 on an Octane. It shows the 3D file browser seen in Jurassic Park.

Matthaeus Krenn presents a concept for car touchscreen UI where the screen controls only one thing at a time, designed to suit driving. A tablet prototype accompanies the short demo.

A three-minute minutephysics video on the orbital mechanics of why crashing into the Sun takes far more energy than leaving the solar system.

A one-minute Volvo Trucks demo of the Collision Warning with Emergency Brake system on a fully loaded 40-ton tractor-trailer, avoiding a rear-end collision on a test track.

A TU Vienna demo of a double inverted pendulum on a cart, using constrained feedforward and optimal feedback control for swing-up and point-to-point motion.

An early 2009 tech test by Notch of an Infiniminer-style cave game running about 700 fps on a 256x256x64 tile map. It is the prototype that grew into Minecraft.

Promotional video from Zapata Racing showing Franky Zapata flying the Flyboard Air prototype, claiming autonomous flight to 10,000 feet, 150 km/h top speed and 10 minutes of endurance.

A short clip of a 2014 Mercedes S-Class driving itself with adaptive cruise control and Active Lane Assist, with the hands-on-wheel timeout defeated.

A short clip of a Volvo C60 automatic braking demonstration in which the car fails to stop. It was widely circulated as a press-demo embarrassment.

A short clip of the famous Hitchhiker-style circular narration of a missile guidance system explaining how it knows where it is by knowing where it isn't. It is a deadpan bit of technical-sounding absurdity about subtraction and navigation.

A SpaceX concept animation of a Falcon 9 and Dragon launch with powered vertical return of both stages and the capsule. It was uploaded to YouTube in 2011.

A short video built around Douglas Crockford, creator of JSON, saying JavaScript is a flawed language and that developers should eventually move on from it. It is a brief commentary clip with little technical detail.

A short excerpt of Rob Pike's Lang.NEXT 2014 talk where he describes Go's target audience as young Google programmers who are not researchers. The language has to be easy for them to understand and adopt.

A four-minute tour of the TeXmacs scientific editor, showing math typing, figures, citations, a drawing tool, document styles, HTML export, presentations and animations.

A short demonstration comparing just intonation with equal temperament, played so you can hear how the tuning compromise changes intervals and chords. It includes a Bach prelude played in both tunings.
