Joe Armstrong, co-inventor of Erlang, gives a funny and opinionated Strange Loop talk on the tangled state of software: build tools, package managers, entropy and the physical limits of computation. He argues for ideas like naming things by content hash and throwing away your first version.

Michael Hendricks of PriceCharting shares tricks and pain points from running Prolog in production for 18 months at Strange Loop. It argues Prolog is a productive modern language beyond logic puzzles, and includes a demo of changing code mid-execution.

Evan Czaplicki's Strange Loop 2014 talk surveys the many formulations of functional reactive programming and how they relate historically and theoretically. It then shows how Elm's variant enables hot-swapping and its time-traveling debugger.

Jon Moore's Strange Loop 2017 talk argues that rate limiting is the wrong tool for protecting services from noisy clients. He proposes concurrency-based capacity management and quotas instead.

Aditya Siram introduces ATS, a statically typed ML-like language that compiles to C and offers type-safe pointer arithmetic and a full proof language. The Strange Loop talk shows off C interop, concurrency and verification features with non-trivial examples.

Devine Lu Linvega of Hundred Rabbits talks about low-power, offline computing, esoteric languages and the Uxn virtual machine, informed by years of sailing the Pacific. The talk frames computing sustainability through a permaculture lens.

Chris Granger presents Eve, a programming environment designed to be approachable for humans, at Strange Loop 2015. The talk covers the project's approach and design ideas.

Michael Arntzenius's Strange Loop talk on Datafun, a functional query language that brings database-style querying into a general-purpose language. It discusses bridging database theory and programming languages.

Will Wilson of FoundationDB explains how the team tested their distributed database using deterministic simulation. By running the whole system in a simulator with injected faults and reproducible seeds, they could find rare concurrency and network bugs.

Evan Czaplicki, creator of Elm, discusses the hard parts of running an open source project: online community conflict, why its patterns arise, and a cultural history of open source. He offers ideas for more civil, productive communication.

Aditya Siram introduces Shen, a small hosted Lisp with macros, a built-in Prolog and an optional type system. The talk demos a full web app moving between functional, logic and imperative styles, including turning JSON into a type with macros.

Richard Feldman describes introducing Elm into a mixed React and jQuery front-end in production, and why the result was reliable, clean and fast enough to make the back-end team jealous.

Physicist Carlo Rovelli gives a public lecture at the Royal Institution on how our understanding of time has changed, from Boltzmann and Einstein to quantum theory and loop quantum gravity. He blends physics, philosophy and art to argue that time is stranger than everyday intuition suggests.

Not Just Bikes argues that self-driving cars will worsen sprawl and car dependence and harm cities. The video compares car-centered and people-centered urban design and weighs what cities should do instead.

Climate Town traces the history of American parking minimums, how they came from shaky research and ITE guides, and how they shape zoning, cities and housing costs. It is a long, comedic video essay.

A 52-minute short version of the documentary The End of Suburbia, about peak oil and the end of cheap energy. It argues that American suburbs depend on cheap oil and may become the slums of the future.

Patrick Boyle's deadpan account of Saudi Arabia's Neom and The Line megaproject, a planned 170 km linear city that has been scaled back to a fraction of its size. He covers the feasibility problems and the financing.

Physicist Geoffrey West speaks at an FQXi conference on time about complexity and scaling laws. He covers how metabolism, growth and lifespan scale across organisms and how the same mathematics applies to cities and companies.

Not Just Bikes compares the same cycling trip to a hardware store in Calgary and in Amsterdam, using a 'plus 1 minus 2' format. It shows how street design shapes how safe and practical cycling is.

A snarky, comedic video essay from Climate Town, with a guest appearance by Not Just Bikes, arguing that American suburban sprawl and single-family zoning are financially and environmentally unsustainable. It covers how zoning rules shape housing and what viewers can do locally, such as attending zoning meetings.

Wendover Productions explains how UK rail privatization worked and why it failed. It covers the fragmented operator and infrastructure structure and why market forces apply poorly to rail.

An Odd Lots podcast episode on why converting empty office buildings into apartments is hard. A managing director at Vanbarton Group walks through the zoning, financing and construction obstacles, mostly in New York.

James Howard Kunstler's TED talk argues that American public spaces and architecture have become unworthy of care, damaging civic life. He presents suburban sprawl and car-first design as failures of the common good.

Not Just Bikes argues that oversized American fire trucks and fire department requirements push cities toward wide roads and dangerous street design. He compares this with the Dutch approach to emergency response.

Wendover Productions explains why Amtrak trains run late: most Amtrak routes run on freight-owned track, and the law giving passenger trains priority is rarely enforced. The video covers rail ownership versus control and how freight carriers hold the leverage.

Charles Marohn of Strong Towns presents, in a Talks at Google session, the ideas from his book on why many North American towns struggle financially despite decades of growth. He argues for incremental, bottom-up city building as a path to local prosperity.
