Jon Gjengset's roughly four-hour live stream implementing part of a BitTorrent client in Rust, following CodeCrafters' test-guided challenge. He builds from scratch and shows idiomatic error handling along the way.

Ben Felix explains how to decide between renting and buying a home, weighing financial and non-financial factors. He argues that renting is often as good or better than owning, both financially and for well-being.

A UC Berkeley CS 161 lecture by Nicholas Weaver on cryptocurrency and blockchains, covering how they work and the case against them. It is aimed at a computer security course audience.

An excerpt from a Bay Area Rust meetup on Servo's WebRender, which renders CSS display lists on the GPU at very high frame rates. It explains the approach and demos rendering at around 500 FPS.

A sketch from the British sitcom Yes, Prime Minister in which Jim Hacker and the chief scientific advisor discuss the logic of the nuclear deterrent.

A John Oliver Last Week Tonight segment on how forensic science used in criminal trials is often unscientific. It looks at unreliable methods and lab malpractice, and ends with a joke about a TV procedural that might change public perception.

A demo excerpt from a 2016 Bay Area Rust meetup showing Servo's WebRender drawing CSS on the GPU at very high frame rates. It presents the promise of GPU-based browser rendering.

A one-minute NVIDIA research demo of foveated rendering for VR using SMI eye tracking. It renders at full detail only where the eye is looking, matching the physiology of human vision.

A scene from Children of Men in which Theo visits Nigel in the Ark of the Arts to get transit papers. It features Nigel's line "I just don't think about it" and a one-handed chorded keyboard.

A short side-by-side recording by Jake Archibald of the same animation demo running in Chrome, Firefox, Safari and Servo WebRender nightlies on a 60Hz display. It shows the smoothness difference of GPU-based rendering.

Conal Elliott presents his paper on automatic differentiation, deriving a simple, generalized AD algorithm from a natural specification. Varying the representation of derivatives yields forward and reverse mode algorithms that avoid the complexity and statefulness of backpropagation.

David MacKay's TEDxWarwick talk uses basic arithmetic to show how much land and energy renewables would need to power a country like the UK. It explains the limits of sustainable options and why they should still be pursued.

Michael Shellenberger argues in a TEDx talk that solar and wind need huge amounts of land and mining, and says nuclear power is a better path to protecting both the climate and nature.

Rob Pike's 2010 talk at OSCON's Emerging Languages Camp on where Go's concurrency style comes from. It traces the idea from Hoare's CSP through Squeak, Newsqueak and Limbo to Go.

Jonathan Worthington's YAPC Asia 2015 talk on parallelism, concurrency and asynchrony in Perl 6. It covers the language's concurrency features.

A GDC 2015 talk in which Natalya Tatarchuk describes the multithreaded renderer Bungie built for Destiny. It covers the low-latency architecture across platforms, its successes and its challenges.

Hillel Wayne's Strange Loop talk introducing TLA+ as a specification language for finding concurrency bugs in designs. It covers stalling, race conditions and dropped messages, with PlusCal examples.

Mentalist Derren Brown plays nine skilled English chess players, including four grandmasters, simultaneously on his TV show. The trick behind the apparent win is the point of the segment.

Lawrence Lessig's Talks at Google presentation based on his book Republic, Lost, arguing that money in politics corrupts Congress and eroded public trust, and outlining what could be done about it. It supports the argument with data on political donations.

Rob Pike's Google I/O 2012 talk shows how goroutines and channels solve tricky concurrency problems with simple Go code. It features a playful goroutine demo with gophers passing messages and a search engine example.

Rich Hickey's long presentation on Clojure and concurrency covers locking and immutability, then goes in depth on refs, transactions and agents. It ends with a multithreaded ant colony simulation demo.

Raymond Hettinger's PyBay 2017 keynote on concurrency in Python. It covers threads, processes, asyncio, locks and the GIL, with live shell-based examples.

An excerpt of the 2005 Harvard debate in which Steven Pinker gives his prepared case on biological sex differences and the under-representation of women in science. It covers cross-cultural patterns in preferences and abilities and the overlap between male and female distributions.

A panel with Tony Hoare, Joe Armstrong and Carl Hewitt, hosted by Francesco Cesarini, on the history and future of concurrency. The three creators of CSP, Erlang and the actor model discuss their differing approaches.

Andreas Kling ports the game Diablo to SerenityOS, his from-scratch Unix-like operating system, using the devilutionX project. The roughly 80-minute session shows what porting third-party software to the OS involves.

Ben Felix argues that common beliefs about renting versus buying are wrong: homes are not great investments, mortgages are not a wealth hack, and ownership does not reliably bring happiness.

Karen Sandler's keynote at Linux.conf.au 2012 on the software running inside medical devices such as her own pacemaker-defibrillator. She discusses the difficulty of learning what code runs in life-sustaining devices and why open source matters there.

MIT professor Donald Sadoway argues that grid-scale storage is the missing piece for renewable energy. He sketches at the blackboard how large, cheap liquid-metal batteries could store wind and solar power.
