A Corridor Digital parody of a Boston Dynamics promo, showing a CGI military robot trained for combat that goes rogue and refuses to kill a robotic dog.

John Sotos, a physician and former Intel chief medical officer, argues at DEF CON 25 that genetic diseases are exploitable vulnerabilities in the genome. He warns that CRISPR and related tools will make malicious genome hacks and targeted bioweapons feasible.

PBS Space Time explains the quantum eraser experiment, in which erasing which-path information appears to reverse causality in a double-slit setup. It discusses what this means for quantum mechanics.

A PBS Space Time episode introducing de Broglie-Bohm pilot wave theory, an interpretation of quantum mechanics that avoids much of the strangeness of the mainstream views. It is aimed at curious lay viewers.

A PBS Space Time episode asking what matter, mass, and energy really are, starting with inertial versus gravitational mass and what mass-energy equivalence means.

PBS Space Time introduces Miguel Alcubierre's warp drive, explaining how spacetime itself could be warped rather than moving a ship through it, and whether it is physically possible.

PBS Space Time explains what happens as you approach and cross a black hole's event horizon, using Penrose diagrams and light cones as the tool for understanding spacetime there.

PBS Space Time explains the Higgs field and how the Higgs mechanism gives particles mass within quantum field theory. It is a ten-minute overview for a lay audience.

PBS Space Time explains the Bohr-Einstein debate over quantum mechanics and how quantum entanglement settled it. It covers the weirdness of measurement and nonlocal correlations.

The 1992 SIIA anti-piracy rap video Don't Copy That Floppy, warning kids against copying software, remastered and uploaded.

Technology Connections shows a cheap method for capturing analog video: a composite-to-HDMI upscaler feeding an HDMI capture dongle, aimed at digitizing home movies and VHS tapes.

Dick Hardt's fast-paced OSCON keynote on Identity 2.0 and the move toward user-centric digital identity. It is also famous for its rapid-fire, many-slide presentation style.

Ben Eater shows how to build logic gates out of transistors, including NOR gates. It is part of his clear hardware-from-scratch teaching style.

Ben Eater finishes building a minimal VGA video card from logic circuits. He explains analog RGB signals, stores an image in an EEPROM and builds a simple digital-to-analog converter to display it.

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 short Australian dystopian film in which a man returns home to find citizens fining each other for infractions via a government app, with cameras everywhere.

TED curator Chris Anderson interviews Linus Torvalds about his personality, his engineer's pragmatism, and the creation of Linux and Git. Torvalds also discusses taste in code and why he open sourced Linux.

Ben Eater's short update announcing his plan to build another 8-bit computer from scratch on camera. It kicks off the breadboard computer series that became widely known.

Ben Eater starts a series building a working computer on breadboards around the 6502 microprocessor. In this first part he gets a 'hello world' running from scratch.

Cory Doctorow's 28c3 keynote argues that the copyright wars were just a skirmish and that the real fight will be a war on the general-purpose computer. He explains why locked-down devices, DRM and surveillance tools all depend on removing general computation.

Cory Doctorow's Talks at Google lecture on the coming civil war over general-purpose computing. He argues that locked-down devices, DRM, and surveillance threaten user control of computers.

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.

Moxie Marlinspike's DEF CON 18 talk argues that privacy threats have shifted from centralized state databases like TIA to corporate data collection by companies like Google, despite wins in strong cryptography and decentralization.
