A WIRED Future Cities documentary on Shenzhen, covering its hardware-prototyping culture and shanzhai copycat manufacturing. It looks at how the city's ecosystem evolved and what the rest of the world can learn.

Tom Murphy (suckerpinch) presents a deliberately trollish computer architecture built on IEEE-754 floating point, using NaN and infinity to define logic gates. He builds working hardware around the idea.

The first video in Not Just Bikes' Strong Towns series explains the financial instability of North American cities, based on Strong Towns research. It argues that low-density suburban growth costs more to maintain than it brings in.

The School of Life sets out principles for making attractive cities, arguing that the art has been lost in the modern world.

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 takes on the common excuse that a country is simply too big or spread out for good transit and walkable cities. The video argues that city density and short everyday trips matter, not national size or overall population density.

Part 3 of WIRED's Future Cities series on Shenzhen. It examines how attitudes toward patents and intellectual property differ from the West, and how shanzhai (copycat) manufacturing created an ecosystem of rapid iteration and distribution.

Not Just Bikes contrasts traditional and suburban development in North America. It looks at the financials behind each pattern and argues that suburban development leaves cities unable to pay for their own infrastructure.

A Vox explainer on how mandatory parking minimums and free parking impose hidden costs on cities. It draws on Donald Shoup's work and gives the history of parking requirements.

Not Just Bikes explains the Strong Towns argument that car-dependent American suburbs cost more to maintain than they generate in taxes. It describes the growth Ponzi scheme that props up municipal finances.

CGP Grey explains the City of London's unusual governance, including the Lord Mayor, guilds, and how it differs from the rest of London.

Not Just Bikes explains how many American suburbs, built all at once rather than incrementally, cannot cover their infrastructure costs and survive on growing debt. It draws on Strong Towns' work on the growth Ponzi scheme.

Not Just Bikes argues that people in walkable, bikeable Dutch cities stay healthy because exercise is built into daily life, which he calls the gym of life. It contrasts this with car-dependent cities that require deliberate workouts.

A video essay from Every Frame a Painting about Vancouver, a major film production city that almost never appears onscreen as itself. It shows clips of films and TV shot there that pass the city off as somewhere else.

A PBS Space Time episode asking whether Venus would be a better colonization target than Mars. It covers Venus's habitable altitudes, floating balloon habitats, and the term surfacism.

A Climate Town video on how the auto industry reshaped American cities and culture through advertising, lobbying and campaigns like the 1939 World's Fair. It is snarky in tone but backed by a published source document.

Sandy Pentland of MIT presents his book on social physics, which uses big-data studies of how people interact to explain how ideas spread. He describes findings on collective intelligence and social influence.

Jason Scott of Archive Team describes how a loose band of volunteers rushes to copy sites like Geocities, Friendster and Yahoo Video before their owners delete them. The talk covers the tactics they use and the argument that this data is history worth saving.

Kyle Drake of Neocities explains the bandwidth pricing pitfalls of the big cloud providers. He describes how to run high-volume, bandwidth-heavy infrastructure far more cheaply, including through co-location.

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.

An Isaac Arthur episode on arcologies, self-sufficient habitats that could house whole cities, on Earth or on harsh worlds. It covers how such structures might work and what limits their size.

PolyMatter explains China's housing bubble and why around 50 million homes sit empty. It covers cultural and economic reasons behind the overbuilding and the government's bind.

The ADVChina hosts tour a villa neighborhood in southern China that was built only three years earlier and is already empty and deteriorating. They use it to discuss ghost cities, building quality and the real estate bubble.

ADVChina tours Chinese ghost cities and discusses the housing bubble, with speculative buyers purchasing empty apartments as investments.

A 95-minute recorded debate at the ARITH23 computer arithmetic conference between John Gustafson, proponent of unums/posits, and William Kahan, architect of IEEE 754 floating point. They argue the merits of the new number formats versus conventional floats and interval arithmetic.

Not Just Bikes explains why living in a dense, bikeable Dutch city sharply reduced his family's environmental footprint and improved quality of life. It is a collaboration that continues on Climate Town.

Not Just Bikes visits Paris to see how Mayor Anne Hidalgo's policies are turning it into a '100% cyclable' city. It looks at the changes that took space from cars for bikes and people.

Cities: Skylines experiment measuring traffic flow across 30 different four-way junction designs, comparing vanilla traffic AI with the TMPE mod.

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.
