A short clip demonstrating a phone-based social engineering trick in which a crying baby in the background is used to pressure a customer service rep. It shows how attackers exploit human sympathy rather than technical flaws.

A roughly two-hour demonstration by Dan Ingalls of Smalltalk running on the Computer History Museum's restored Xerox Alto. It shows the integrated environment and language designed at Xerox PARC as personal dynamic media.

Kyle Hill of Because Science explains and demonstrates, using real cards, how Magic: The Gathering can be used to build a Turing machine, a computer inside the card game.

Dave Jones of EEVblog tears down a Kollsman MD-1 Automatic Astro Compass, a mechanical analog computer from a B-52 bomber. It is part of a star-tracker inertial navigation system that computes altitude and azimuth.

Dave Jones of EEVblog tears down an Esinomed Infoview medical tablet computer built around an 800MHz AMD Geode board, exposing extremely shoddy construction and design.

The 8-Bit Guy reviews the Color Maximite 2, a modern ARM-based computer that boots straight into BASIC. He shows what it can do as a retro-style machine.

A NASA and Durham University supercomputer simulation suggesting the Moon may have formed within hours of a giant impact between Earth and a Mars-sized body. It is one of the highest-resolution giant-impact simulations run.

A short demonstration of the MONIAC, Bill Phillips' hydro-mechanical economic computer, at the Reserve Bank of New Zealand museum. It shows how water flows model an economy's money flows.

A short clip of the Harwell Dekatron/WITCH, the world's oldest original working digital computer from 1951, being restarted at The National Museum of Computing in 2012.

A Belgian bank-safety campaign video in which a supposed clairvoyant stuns people by revealing personal financial details, then shows he found them all online. It warns viewers to be careful about what they share and about online banking security.

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

Tom7 explains and demos software that learns to play NES games by finding score patterns in memory and then searching for inputs that raise it. It is the video companion to his SIGBOVIK paper.

A maker's time-lapse of building a working computer inside a LEGO-style brick, using a tiny 0.42-inch OLED screen, with a demo at the end.
