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.

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.

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.

Jenny Nicholson's roughly four-hour review of her two-night stay on Disney's Star Wars Galactic Starcruiser immersive hotel. She goes through the experience, its story and production, and why it failed.

A short clip of the audience at Valve's 2017 announcement of Artifact, a Dota 2 card game, reacting with visible disappointment. The footage captures the awkward silence and the logo reveal.

Scott Forstall demonstrates Siri on stage at Apple's October 2011 iPhone 4S event, showing the voice assistant handling natural requests like checking the weather and getting things done by asking.

A one-minute clip of Windows Phone 7 and Bing product placement from an episode of Hawaii Five-0, in which a character says 'Bing it!' and another checks a Windows phone.

Technology Connections explains why electric kettles are uncommon in the US, centering on 120V circuits limiting power. He tests ways of boiling water on gas, electric ranges and kettles.

Technology Connections explains weaknesses in the US electrical system, centering on how cord and circuit ratings can mismatch and cause fires. It covers extension cords, power strips and plug history in about 25 minutes.

Technology Connections' hour-long guide to electric vehicles, covering costs, trade-offs and especially how little home charging power most drivers need.

Technology Connections takes apart a 1970 Wurlitzer 3400 jukebox to show how electromechanical relays and switches automated its behavior without a computer.

An episode of REACT in which children try to figure out 1970s-1980s computers, including an Apple II and floppy disks. It was made to promote the AMC show Halt and Catch Fire.

Python core developer Raymond Hettinger explains how Python's dictionary implementation evolved into the compact, ordered dict in Python 3.6. He uses pictures and small bits of pure Python, and covers key-sharing, compaction and versioning.

A short excerpt from Dr Russell Barkley's 2012 Burnett Lecture on ADHD, focused on treatment. He argues ADHD is a disorder of executive function and self-regulation, and that environments should be designed to compensate.

Pete Hunt of Facebook and Instagram introduces React at JSConf EU 2013 and explains its design principles. He argues that separating templates from logic only separates technologies, not concerns, and makes the case for components.
