The Monorail song scene from The Simpsons, uploaded with a note comparing it to a local Australian development controversy.

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.

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.

Sean Parent's GoingNative 2013 talk surveys new and overlooked C++ features and shows how to use them for simple, correct, clear code. It stresses using standard algorithms rather than raw loops.

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.

Velcro Brand's legal team makes a short, humorous ad asking people not to use "velcro" as a noun or verb and to say hook and loop instead. It is a tongue-in-cheek lesson in defending a trademark against genericization.

Velcro's follow-up to its "Don't Say Velcro" ad responds to viewer feedback, with a humorous take on trademark usage and alternative names for hook and loop fasteners.

Ben Krasnow of Applied Science builds a DIY microbalance from an analog panel meter with an optical servo loop. It reaches about 5 micrograms of precision and is used to weigh a single eyelash at around 35 micrograms.

A controlled demonstration by Wabash National of a tank trailer collapsing under vacuum, staged at an industry expo. The tank implodes as air is pulled out.

A Community clip in which Dean Pelton explores a virtual reality environment, including a blooper moment.

A short BicycleDutch video on how the Netherlands got its cycling infrastructure, including the 1970s protests and the shift away from car-centric planning. The channel later published an updated version.

A four-minute Not Just Bikes comparison of grocery shopping in Amsterdam versus car-centric North America, arguing that frequent small fresh-food trips beat bulk shopping. It ties this to land use and reduced food waste.

Seattle landscape architect Fred Young gives an hour-long visual tour of Dutch cycling infrastructure, covering design details, continuous networks and how cycling fits daily life in the Netherlands.

Technology Connections explains how LED traffic lights, which do not melt snow, drew complaints and were blamed for accidents. He uses it to illustrate the 'but sometimes' fallacy against new technology.

CGP Grey explains how traffic jams come from human driving behavior such as tailgating and reaction delays, and how leaving gaps and smoothing speed would reduce congestion. It also touches on self-driving cars.

Wendover Productions explains why US passenger rail lags behind other countries. It covers freight companies owning most of the track, geography and population density, and the economics of competing with flying.

The first episode of a Cities: Skylines series on urban politics and planning, focused on parking. It uses the game to show how parking minimums shape cities, drawing on Donald Shoup's book The High Cost of Free Parking.

ReasonTV tells the story of Bob Tillman, who spent nearly five years and $1.4 million trying to convert his San Francisco laundromat into apartments. It walks through the permitting, appeals and neighborhood opposition he faced.

A short BicycleDutch episode showing how people with disabilities use Dutch cycle tracks on hand-cycles, tricycles and mobility scooters.

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.
