Christopher Hitchens delivers a speech defending freedom of speech, including the right of audiences to hear offensive speakers and a take on the fire-in-a-crowded-theatre line. It is framed around the Charlie Hebdo attack.

Dan Olson's long Folding Ideas video on the GameStop meme stock phenomenon, its online community and the conspiracy thinking around it. It runs over two hours.

Christopher Domas presents his Cantor Dust tool at Derbycon 2012, a 3D visual approach to reverse engineering binaries by visualizing their structure dynamically.

Christopher Alexander's keynote at OOPSLA 1996 on patterns in architecture, addressed to the software community. He moves beyond patterns toward deeper ideas of wholeness and living structure.

Destin of Smarter Every Day films a cat falling in high-speed slow motion to show how cats right themselves in midair, and introduces the physics behind it.

Rob Miles explains on Computerphile why implementing an off switch for a general AI is hard. A capable agent would resist being stopped because shutdown prevents it from achieving its goal.

An excerpt from Russell Barkley's lecture on ADHD, focusing on inhibition, impulsivity and emotional regulation. It explains ADHD as a problem of response inhibition and emotional impulsivity.

Ten minutes of ultra-slow-motion footage of bullet impacts filmed at about one million frames per second by Werner Mehl of Kurzzeit. It includes hollow points in ballistics gel and impacts on glass.

IBM's record-setting stop-motion film made by moving individual carbon monoxide molecules with a scanning tunneling microscope, illustrating atomic-scale memory research.

A very short demo of SmackBook, a hack that used the MacBook Pro's sudden motion sensor so that smacking the sides of the laptop switches desktop spaces.

A short National Geographic piece showing a laser system that tracks and kills mosquitoes, filmed in slow motion, as part of anti-malaria efforts. It comes from Intellectual Ventures' 2010 work.

A one-minute Robot Chicken stop-motion sketch where Darth Vader keeps altering his deal with Lando Calrissian.

A short Harris Corporation (L3Harris) promotional video showing wide-area airborne motion imagery, a sensor system for persistent real-time aerial surveillance of large areas.

Smarter Every Day uses high-speed and Schlieren photography to show how a whip crack is a supersonic shockwave formed at the tip. It references academic papers on whip physics.

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.

A classic Bob Newhart comedy sketch in which a therapist's only advice to a patient is to 'stop it'.

A two-minute Insider Tech clip on DeepMind's simulated agents that learned to walk, run, jump and climb without guidance, with the goofy resulting gaits.

Christopher Domas's Derbycon 2015 talk on the M/o/Vfuscator, a compiler that emits only x86 mov instructions, showing mov is Turing complete. It explains how a full machine is built from mov and why the output is a nightmare to reverse engineer.

A Boeing 737 pilot explains the runaway stabilizer checklist, the procedure for stopping unwanted horizontal stabilizer movement such as an MCAS activation on the 737 MAX. He walks through the steps, the trim cutout switches and the jackscrew mechanism, and shows a simulator run including the manual trim wheel effort.

Christopher Domas presents research at DEF CON 26 showing a hidden alternate instruction set and undocumented hardware backdoor in some x86 processors, found on a third-party CPU. He uses it to ask how feasible wider hardware backdoors are.

A three-hour PyCon 2016 tutorial by Christophe Pettus that orients Python developers to PostgreSQL. It covers installation, administration, and use, including vacuuming, MVCC, replication and backups.

Christopher Domas's REcon 2013 talk on dynamic binary visualization for reverse engineering. He shows how rendering binary data as interactive visual maps and trigraphs reveals structure that hex dumps hide, leading to his Cantor.dust tool.

Christopher Domas's DEF CON 26 talk on secret processor registers that vendors reserve for third parties holding trusted keys. He examines how users are locked out of parts of their own CPUs.

Captain Disillusion explains the visual effects behind the Back to the Future trilogy. He covers ILM's motion-control, computer-controlled camera work and clever pre-CGI tricks.

David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.
