Kiran Pamnany's Cambridge Julia Meetup talk on Julia's shared memory parallelism and its new task scheduler. It argues that fork-join and work-stealing models nest poorly and presents depth-first scheduling for composable parallelism.

Jack Moffitt presents Servo, an experimental browser engine written in Rust and designed to be parallel at every level, using multiple cores, the GPU, fork-join concurrency and SIMD. The talk covers motivations, architecture and plans for the project.

Guy Steele presents a small geometric problem and compares four computational approaches: a classic sequential solution and three parallel-friendly ones. Each is illustrated pictorially and with working code, weighing total work against time to solution.

Jim Keller's talk at the 2020 Scaled Machine Learning conference on Moore's Law in the age of AI chips. He compares scalar, vector and GPU-style parallel approaches to computation.

Styropyro wires 100 car batteries in parallel to produce more current than a lightning bolt and tests what happens when it is shorted. The experiments, done with other YouTubers, show spectacular effects of extreme current.

A two-hour live stream in which Aaron Hsu explains the architecture, design history and aesthetic of Co-dfns, his parallel APL compiler. He walks through the code and the reasoning behind its dense style.

Jack Moffitt presents the architecture of Servo, Mozilla's experimental browser engine written in Rust, focusing on parallelism across cores, GPUs and SIMD and the safety properties gained from Rust.

Kurzgesagt explores the idea that black holes could create universes and that we might live inside one. It builds up the physics of how density falls as black holes get larger.

Guy Steele's JuliaCon 2016 keynote on the Fortress language, its features and the lessons learned from the project.

Gary Bernhardt's RubyConf 2012 talk on testing in isolation without mocking everything. It goes through behavior versus data, mutation versus immutability, and how a functional core with an imperative shell yields natural isolation and parallelism.

DIY Perks builds a realistic artificial sun for dark winters, using a powerful water-cooled LED, a satellite dish reflector for near-parallel rays, and a scattering layer to mimic the blue sky. The video explains the optics behind why most lamps do not look like sunlight and shows the build and its results.

Skateboarding pioneer Rodney Mullen talks about how the open skate community and its environments drive the invention of new tricks out of pure passion. He draws parallels to collaboration and open source.

Andrew Adams, a Halide developer, presents the Halide language for image processing and tensor computation. The talk explains the separation of algorithm from schedule with illustrated examples of parallelism, locality and redundancy tradeoffs.

Sasa Juric's EMPEX talk demonstrates Elixir and Erlang's process model and what makes the BEAM runtime distinctive, such as fault-tolerant parallelism by design.

Aaron Hsu shows how to manipulate and transform tree data in APL using arrays and inverted tables instead of pointers. He claims much smaller code, better performance and easier parallelisation.

A BBC Weird Nature clip about vervet monkeys in the Caribbean that drink alcohol, and how they split into heavy drinkers, social drinkers and teetotalers.

Joe Armstrong's Strange Loop 2013 talk on building large scalable systems from small isolated parallel components. It covers detecting and correcting errors at run time, changing code while it runs, and how Erlang embodies these principles.

A two-minute clip of comedian Bill Hicks doing his routine on marketing and advertising, with explicit language. He mocks marketers and urges them to get out of the business.

Isaac Arthur examines Dyson spheres and swarms, including common myths and misconceptions. He covers uses such as interstellar travel, black hole generation, and computing large enough to simulate universes.

Chalmers Johnson, author of Blowback and Sorrows of Empire, lectures on parallels between the decline of the Roman and Soviet empires and the United States. He argues the US shows the same symptoms: overextension, corruption, and an inability to reform.

The second talk in the Mill CPU series by Mill Computing, covering the Belt, the Mill's operand-passing model that replaces general registers. It explains the cost of register renaming in conventional wide CPUs and how the Belt reaches high instruction-level parallelism.

Physicist Angela Collier critiques 'vibe physics', the idea that non-experts or billionaires can make scientific discoveries by chatting with AI chatbots, drawing a parallel with vibe coding.

David Ditzel of Esperanto Technologies presents their massively parallel, energy-efficient RISC-V processors at the 7th RISC-V Workshop in 2017. It covers the high-performance many-core design aimed at machine learning.

Practical Engineering summarizes the 2017 Oroville Dam spillway failure, explaining the engineering details behind the incident. It also discusses how operators and regulators failed to keep downstream residents safe.

Veritasium explores what general relativity says about black holes, white holes and wormholes, with help from physicists Geraint Lewis and Juan Maldacena. It introduces Penrose diagrams and the idea that other universes may be implied.

A restored 1994 video of Karl Sims' research on evolved virtual creatures, where simulated block creatures are bred through artificial evolution to swim, walk, follow and compete. It is a landmark demonstration of genetic algorithms in physics simulation.

A hands-on comparison of self-parking systems on a Tesla Model S and 3 (including AP1 vs AP2), an Audi e-tron GT, a Ford Mustang Mach-E and a BMW i4 M50. It tests both parallel and perpendicular parking and finds Tesla's newer vision-based parking noticeably weaker than the others.
