A guest video by Welch Labs on 3Blue1Brown explaining how text-to-image and video models work. It covers CLIP, shared embedding spaces, diffusion models (DDPM, DDIM), conditioning, guidance and negative prompts.

The first part of Welch Labs' series on imaginary numbers, presenting them as the natural extension of the number line into two dimensions. It covers the history and the math with strong visuals.

The first of a short series by Welch Labs on building a complete neural network in Python. It introduces the data and the architecture of a simple network before later parts cover forward propagation, gradient descent, and backpropagation.

A 1973 AT&T training film made for new employees at Bell Labs' Holmdel Computing Center, when Unix was in its third version and running at 16 computer centers in the Bell System. It shows how users submitted jobs and used the center's machines.

Anthony Marcar describes lessons from three years of using Clojure at WalmartLabs, including scaling a team and a large multi-project codebase in an enterprise setting.

Computerphile with Professor Brailsford on how a 1979 Bell Labs team reverse engineered a Linotron 202 phototypesetter over a summer to get high-quality print output. It covers typesetting history and the later 2013 rebuild of the famous vacation memo.

A Welch Labs explainer on neural scaling laws and the compute-efficient frontier, asking why model loss seems to hit a line it cannot cross. It draws an analogy to an ideal gas law for AI.

Redis Labs and Tim Davis present RedisGraph, which uses GraphBLAS to treat graph queries in Cypher as sparse linear algebra for lower latency.

A Bell Labs film in which Dr. J.N. Shive uses a mechanical wave machine to demonstrate reflection, standing waves, resonance and impedance matching. He includes some equations but relies mostly on real-world examples a layperson can follow.

R. Stanley Williams of HP Labs gives a keynote on the memristor, covering the physics, crossbar computation, and potential for memory and new computer architectures.

Brian Kernighan interviews Unix co-creator Ken Thompson at VCF East 2019. Thompson recounts how he was hired at Bell Labs, writing the Unix kernel in about three weeks, the origins of B and TMG, pipes, and other anecdotes.

Richard Hamming's 1995 recording of his talk 'You and Your Research', drawn from his graduate engineering course. He discusses how great scientists pick important problems and build careers, drawing on his years at Bell Labs.

A 1982 Bell Labs film hosted by Victor Vyssotsky on the origins and design philosophy of the UNIX operating system, with appearances by Kernighan, Thompson and Ritchie. It shows pipes, filters and a shell one-liner spell checker being built.

BobbyBroccoli's first of three parts on Jan Hendrik Schon, the Bell Labs postdoc whose fabricated organic semiconductor results nearly won a Nobel Prize. It covers his rise and the context around Bell Labs.

A 1982 AT&T Bell Labs film for students about the Unix system and how it can be used practically. It includes Lorinda Cherry building a talking calculator by piping together Unix commands, and a spell checker made from Unix utilities.

Tested gets hands-on with four Meta Reality Labs research VR headset prototypes testing resolution, brightness, focus shifting and form factor, plus an interview with Mark Zuckerberg on display technology.

UploadVR covers a Facebook Reality Labs prototype that tracks facial expressions using cameras mounted in a VR headset. The updated version captures subtle micro-expressions for realistic avatars.

Ori Bernstein gives an overview of Plan 9 at a NYC*BUG meeting. He explains what the system is, how it is built, what has happened since Bell Labs, and what its design teaches, with a live demo.

Rob Pike gives an insider's account of the history of Unix and the development of key pieces of modern computing, including Bell Labs anecdotes.

A No Priors podcast conversation with Andrej Karpathy covering self-driving (Tesla versus Waymo), the Optimus robot, bottlenecks in AI development, and his education project Eureka Labs.

A step-by-step tutorial on making a Harry Potter by Balenciaga style AI video, using tools such as ChatGPT, Midjourney and Eleven Labs for script, images and voices.

A short look at the Voder, the first electronic voice synthesizer, demonstrated by Bell Labs at the 1939 World's Fair. It was operated by trained women using ten finger keys, foot pedals and a knee lever.

A two-hour Computer History Museum oral history interview with Bjarne Stroustrup, conducted by Paul McJones in 2015. It covers his youth, education at Aarhus and Cambridge, his career at Bell Labs and elsewhere, and the design and evolution of C++.

Penn and Teller help Rob Pike and Dennis Ritchie of Bell Labs play a prank on Nobel-winning physicist Arno Penzias. The clip shows the gag and its setup.

Part one of Sandia National Labs' first-person documentary on the use control, detonation safety and survivability of US nuclear weapons. It covers nuclear sharing in NATO and how control of use was separated from possession, leading to the always/never problem.

Footage from the Chasing Ice project of the largest glacier calving event ever filmed, at Greenland's Ilulissat Glacier in 2008. A 75-minute event is condensed to a few minutes of cameras watching ice collapse.

OK Go's music video for This Too Shall Pass, featuring a huge Rube Goldberg machine built in a warehouse in Los Angeles with Syyn Labs. The band interacts with the contraption in one continuous take.

The Thought Emporium shows how they engineered a yeast strain to produce real spider silk, after more than two years of lab work and many failures. The video explains the genetic engineering process behind it.

A Seeker short documentary on a lab where robots run experiments with almost no human intervention, covering automation and active machine learning in drug discovery and synthetic biology.

A short AI-generated parody video that imagines Harry Potter as a Balenciaga fashion campaign, made with Midjourney, ChatGPT and Eleven Labs voices. It became a viral meme.
