A WSJ interview in which Apple's Craig Federighi explains Apple's CSAM scanning and child-safety features, including neural hashes and safety vouchers, and defends them against backlash.

A short IBM behind-the-scenes documentary on how researchers moved individual atoms to make the world's smallest movie. It introduces the scientists and their work on atomic memory and data storage.

Rob Pike shows how the Go text/template lexer is built, using state functions, goroutines and channels. The talk was given at a Google Technology User Group in Sydney in 2011.

A demo of the Treventus ScanRobot 2.0 MDS, an automatic book scanner that digitizes very thick books up to 15 cm with gentle handling.

A short live demo of Dental Wings' Virtuo Vivo intraoral scanner at IDS 2019. It shows a fast color scan with a small, lightweight handpiece.

Der8auer visits Tescan and uses an electron microscope to compare real transistor sizes on Intel 14nm and AMD 7nm chips. It shows that process node names do not match physical measurements.

Ben Krasnow of Applied Science uses a scanning electron microscope to compare new and worn toothbrush bristles. He shows how the microscopic texturing wears down with use.

A University of Tokyo lab demonstrates a book scanner that flips pages automatically and scans over 250 pages per minute. It uses real-time 3D recognition of the flipped pages and then restores each one to a flat image.

Dan Tentler shows a rapid-fire tour of insecure things found on the open internet using Shodan and his own scanning, from unprotected VNC endpoints to industrial controls. The emphasis is on how little security was considered before connecting them.

David Kriesel's 31C3 talk, in German, on the discovery that Xerox scanner-copiers silently replace digits and letters in scanned documents. He explains how the bug stayed unnoticed in the wild for years.

A long information session where The Boring Company presents its vision for Loop, an underground high-speed transit system, and the traffic problems it aims to solve. It includes discussion of faster tunnel boring and electrification.

Google engineer Dany Qumsiyeh presents a prototype automatic, non-destructive book scanner that turns pages and captures high-resolution images, built in Google's workshops. The talk includes a live demo and a short technical overview.

A 39-minute BBC documentary, built from earlier British Transport Films footage, on how the London Underground's Victoria Line was dug in the 1960s.

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

A DEF CON 29 talk by Richard Henderson about encoding the EICAR antivirus test string into QR codes and barcodes and scanning them at real systems. Many systems that do not expect such input misbehave or collapse, including a parking garage system.

First video in John Bartholomew's Chess Fundamentals series, focused on spotting undefended pieces. He teaches habits for scanning your own and your opponent's position to avoid hanging pieces.

A 33c3 talk by marcan on reverse engineering the PS4 hardware to run Linux with 3D acceleration. It covers how the console differs from a PC and includes a story about tunneling PCIe over RS-232.

A Wendover Productions explainer on how airport security is designed, covering screening layers, x-ray scanning, and the contrast with Israel's profiling-based approach. It walks through the logic behind why security works the way it does.

The Slow Mo Guys film a TV and screens with a high-speed camera to show how displays build an image. The footage includes CRT-style scanning and how pixels light up over time.

Verge Science's pilot of its Trial & Error series follows amateur scientist Jon Larsen on a hunt for micrometeorites. It shows how tiny space rocks can be found on rooftops and confirmed under a microscope.

A very short microscope clip of a neutrophil chasing a Staphylococcus aureus bacterium, originally from David Rogers at Vanderbilt University. It is a widely reposted piece of immune-system footage.

Technology Connections explains how analog television produced moving images without computers, covering scanning, CRTs and standards like NTSC and PAL. It is part of a series on analog TV.

A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.

A 'leaked' Microsoft video shown at its 2011 MGX conference that mocks Google's Gmail and Apps to promote Office 365. It attacks Google over email scanning and privacy.
