Casey Muratori argues against smart pointers and RAII, advocating grouped-element thinking, zero-is-initialization and stubs as better ways to structure memory and handle errors.

CGP Grey tells the story of Alexander Pope's long takedown of a historian, Thomas Hearne, framed around the quirks of library books and archival research. It is a funny, digressive video essay about literary feuds and tracking down original sources.

Veritasium explains, with expert input, that in general relativity gravity is not a force and objects follow straight paths through curved spacetime, including why standing on the ground means you are accelerating.

Casey Muratori shows how typical 'clean code' object-oriented patterns can cost large factors in performance. He benchmarks them against simpler data-oriented code.

Mentour Pilot's 56-minute account of the MH370 disappearance and what is now known, including the WSPR radio tracking technique and other sensing methods. It was made ahead of renewed search efforts.

Ian Hubert shows quick, unconventional tricks for greenscreen compositing in Blender, as a follow-up to his motion tracking video.

A 57-minute account of Clifford Stoll's tracking of a KGB-linked hacker through Lawrence Berkeley Lab computers in 1986, the story of The Cuckoo's Egg. It covers the FBI and Chaos Computer Club involvement.

Huygens Optics explores the idea that space is a non-linear elastic medium, and uses simulations to show how wave energy might be confined locally into particle-like objects. It touches on inertia, the Schwinger limit and the vacuum as a medium.

Peter Zeihan speaks at Iowa Swine Day 2022 on geopolitics, the end of globalization and agriculture. He argues that supply chains, energy and farm inputs are all about to be disrupted.

A Foresight Institute workshop video with two talks: Shawn Douglas on nanoscale instruments for visualizing small proteins, and Bret Victor on Dynamicland. Victor's part shows biomolecular design built in his Realtalk system with physical objects.

Lex Fridman interviews Harvard astrophysicist Avi Loeb about the interstellar object Oumuamua, aliens and black holes. Loeb lays out his argument that it may be an artifact rather than debris.

Jeff Geerling looks at a Sharp NEC commercial display with a slot for a Raspberry Pi Compute Module. It is a large screen without built-in smart TV features or tracking.

Sabine Hossenfelder explains why she thinks faster-than-light travel may not be ruled out. She argues that the standard objections from special relativity are inconclusive.

Tech Ingredients demonstrates how microwaves work and how they affect objects at range, then shows ways to defend against them. It includes a correction about rectifier output frequency.

A lecture for high school seniors and college freshmen making the case for nuclear power and answering common objections. It is an overview of the channel's more detailed videos on each topic.

FitMC tells how the Nocom exploit let griefers track players across Minecraft's oldest anarchy server, 2b2t, and the fallout that followed.

Sabine Hossenfelder explains superdeterminism as an interpretation of quantum mechanics, addressing common objections and misconceptions, including the worry that it kills free will or science. She ties it to Bell's theorem and hidden variables.

PBS Space Time explores whether time causes gravity, explaining that gravity does not truly warp the flow of time but arises from time gradients. It revisits how gravitational time dilation works in general relativity.

A short Tesla clip showing the Optimus humanoid robot sorting objects autonomously and doing yoga-style stretches. Tesla says its neural network is trained end to end, from video in to controls out.
