A 36C3 talk by Bunnie Huang arguing that open source is necessary but not sufficient for trustworthy hardware, because verifying hardware is destructive and so creates a time-of-check/time-of-use gap. It surveys supply chain security and classes of hardware attacks, and presents the Betrusted approach to narrowing that gap.

Technology Connections explains what forced-air furnaces are, how they work and why they need electricity. He covers combustion, airflow and the parts of a modern furnace.

A short clip from the Netflix series Space Force in which John Malkovich's character delivers a profanity-laden rant about Microsoft.

A US Air Force film on the Heavy Press Program, which built some of the world's largest metal forging and extrusion presses for aircraft, starting from German presses taken after WWII.

A short clip of Robert Sapolsky on how social hierarchy generates chronic stress, drawing on baboon research. It links rank-related stress to heart health and life expectancy.

Asianometry explains the EUV light source inside ASML's lithography machines, where lasers hit falling tin droplets twice to produce 13.5 nm light. It walks through the engineering of the droplet generator, the pre-pulse and main laser, and the plasma that results.

Kaze Emanuar explains how he rewrote and optimized the Super Mario 64 source code so it runs far faster on real N64 hardware. He covers performance bottlenecks and fixes in detail for his ROM hacks.

A reverse engineer walks through fixing a ten-year-old bug in Guitar Hero III without access to its source code, using a disassembler and decompiler. It is technical but explained step by step.

Marco Reps builds and tests an open-source 8.5 digit voltmeter based on CERN's high-precision ADC design. The video walks through assembly, soldering and measurement of the resulting instrument.

An RSA Animate adaptation of a Slavoj Zizek talk on charitable giving and ethical consumerism. It argues that buying products that bundle a charity donation can sustain the system that causes the problems.

Matt Kulukundis reviews two years of Abseil's Swiss table hashtable, covering post-release optimizations, lessons from rolling it out across Google, design choices, and what global monitoring revealed.

Naomi Wu visits the Shenzhen offices of smartphone maker UMIDIGI in person to get them to release source code they owed under the GPLv2, and they comply.

Elm creator Evan Czaplicki's 2018 Elm Europe talk on how to define success for an open source project and language community. It argues against judging projects by GitHub activity and touches on community expectations.

Donnie Berkholz of RedMonk gives a Monki Gras talk arguing that abusive, toxic contributors damage open source projects. He makes the case for removing them from communities.

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.

Cognitive scientist Donald Hoffman argues in this TED talk that evolution shaped perception to track fitness rather than truth. He uses evolutionary simulations and the Australian jewel beetle as examples.

Yosh trains a reinforcement learning agent to drive Trackmania until he can no longer beat it. The video explains how the training works and the design choices involved.

Neuroscientist Beau Lotto runs the audience through color and pattern illusions to show that perception is shaped by context and evolutionary history rather than being a direct readout of the world. The talk is playful and hands-on, and it argues that the brain interprets ambiguous signals.

Marcin Jakubowski of Open Source Ecology presents his plan to open-source blueprints for 50 cheap, buildable farming tools, a "civilization starter kit". He argues that opening the means of production can enable self-sustaining lives.

Poul-Henning Kamp's FOSDEM 2014 talk is a hypothetical account of how an intelligence agency such as the NSA would sabotage open source software, standards and online discussion. It covers Skype's history, OpenSSL and psyops against standards.

Bryan Cantrill's OSCON 2015 talk on moving a proprietary product to open source, drawing on Sun's history with Solaris and illumos, licensing choices and the relicensing after Oracle's acquisition.

Scott Jenson, a veteran UX designer formerly at Apple and Google, argues that the 'UX/UI' split pits programmers against designers and narrows ambition in open source. He makes the case that desktop UX has stagnated and that open source projects could lead experimentation beyond current interaction models.

A one-minute clip of Linus Torvalds telling Nvidia "fuck you" over its lack of support for Linux and open source. It is taken from a Q&A session.

A two-minute BBC Horizon clip demonstrating the McGurk effect, where what you see of a speaker's mouth changes the sound you hear.

A short clip, titled Orwell Comes to America, on reasoning and perception. One HN user links it repeatedly as the science showing human minds are bad at reasoning and do not see reality as it is.

OpenAI's short demo of agents playing hide-and-seek in a simulated environment. Through self-play, the agents develop six progressively more complex strategies and counter-strategies, including tool use.

Vsauce explores whether people in past decades really looked older than people of the same age today, or whether photographic and cultural factors make them seem so. It draws on old photos, yearbooks and perception research.

Evan Czaplicki, creator of Elm, examines how programming languages are funded. He looks at where compiler engineers' salaries come from, why Go has about 5 engineers while Dart has about 30, and how this limits language design.

Tantacrul explains how he and engraver Simon Smith designed the free music notation font for MuseScore 3.6. It draws on the history of the SCORE notation application by Leland Smith.
