Evan Czaplicki, creator of Elm, examines how programming languages are funded. He looks at where compiler engineers' salaries come from, why Go has about 5 engineers while Dart has about 30, and how this limits language design.

Casey Muratori's two-hour talk tracing the history of object-oriented programming back to the 1960s and examining how its ideas, and later entity component systems, came about. It is followed by a Q&A.

Guy Steele's classic 1998 OOPSLA keynote on how a programming language must grow with its user community. He delivers it in a playful style, starting with only monosyllabic words and defining new terms as he goes.

Jack Rusher's Strange Loop 2022 talk argues that most programming languages are still designed around punchcard-era assumptions. He makes the case for live, interactive programming environments, drawing on Lisp, Smalltalk and REPL-driven development.

Guy Steele's Strange Loop 2010 talk argues that programmers should not have to think about parallelism, and that languages should support algorithms built on independence and divide-and-conquer. He also recounts fitting a program onto a single punch card.

Pokey Rule presents Cursorless, a spoken language designed for editing code by voice, built on tree-sitter parsing with smart structural and simple token-level primitives. The talk is from Strange Loop 2023.

Felienne Hermans presents Hedy, a gradual programming language for teaching kids that moves through levels from almost no syntax toward full Python. The talk covers why error messages and syntax are scary for beginners.

A short clip, published by The Sun, of a Russian surface-to-air missile that appears to turn around after launch and hit its own launch site. It was reportedly filmed in Alchevsk during the 2022 war in Ukraine.

A short, sarcastic Half as Interesting video about a tiny freight railway in Canada built to exploit a shipping regulation loophole. It explains how a track just 100 feet long counted as a railway.

Not Just Bikes explains how SUVs and light trucks have grown in size and share of US sales, and why that is dangerous for pedestrians, cyclists and city life. He covers the regulatory loopholes, such as fuel economy rules and the chicken tax, that favored them.

Rich Hickey's Strange Loop 2011 keynote distinguishing 'simple' (not intertwined) from 'easy' (familiar or near at hand). It argues that software complexity comes from complecting things and that we should pick simple constructs.

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.

Veritasium explores the Prisoner's Dilemma and Axelrod's tournaments, showing why tit-for-tat and forgiving strategies win in repeated games. It extends the ideas to cooperation in evolution and conflict.

Rich Hickey's Strange Loop 2011 keynote separates 'simple' (not intertwined) from 'easy' (familiar or near at hand) and argues that software complexity comes from complecting things. It offers a vocabulary for judging designs and abstractions.

A short ProPublica video explaining the "Buy, Borrow, Die" strategy wealthy Americans use to cut taxes. They borrow against appreciating assets instead of selling, and the gains are never taxed at death.

Tom Scott explains Gricean maxims, the unwritten guidelines that shape how we understand each other. He uses examples such as why 'asbestos-free cereal' sounds suspicious.

Munro Live's team breaks down the thermal management system of the Ford Mustang Mach-E and compares it with the Tesla Model Y. They look at parts count, coolant loops and heating approaches.

Lex Fridman interviews economist Richard Wolff, a Marxist, about Marxism, communism, capitalism and worker cooperatives. The conversation runs nearly three hours.

A one-minute demonstration of iOS 14's new paste notification, which revealed popular apps silently reading the clipboard each time they were opened. It credits the mysk research write-up.

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.

Not Just Bikes introduces the "stroad", a street-road hybrid common in the US and Canada that fails at both jobs. He contrasts it with Dutch design, where each road has a single purpose, and covers cost, danger and ugliness.

Not Just Bikes explains why the channel exists, through the creator's walk in suburban Houston. It shows how car-dependent design makes cities hostile to pedestrians.

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.

Not Just Bikes explains how North American speed limits are set and why posted limits matter far less than street design. It argues that drivers follow the road's cues, so safe speeds have to be built into the street.

Not Just Bikes argues that winter is not what stops Canadians cycling, using Oulu, Finland as proof that safe, well-maintained cycling infrastructure enables year-round biking despite harsh weather.

Not Just Bikes argues that urban noise comes mostly from motor vehicles, drawing on the book Curbing Traffic and a visit to Delft, a city that takes noise seriously.

A video explaining why Japanese cities look the way they do, through Japan's national tiered zoning system that permits mixed use and flexible development. It compares this approach with more restrictive zoning elsewhere.

Not Just Bikes argues that the Netherlands, famed for cycling, is also the best country for drivers. It explains how prioritizing walking, cycling and transit makes driving faster and more pleasant.

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.

Oh The Urbanity! argues that most city dwellers live in dense residential neighbourhoods outside downtown, which can be calm and peaceful. It draws on older, denser parts of Toronto and Montreal.

Not Just Bikes argues that car-dependent suburbs rob children of independence, contrasting North American suburbia with Dutch cities where kids walk and bike on their own. It is the creator's remake of an earlier video on the topic.

FortNine argues that e-bikes have injury rates and speeds closer to motorcycles than to pedal bikes. It argues riders should treat them with similar safety gear and caution.

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.

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.

Not Just Bikes explains, using Urban3's property-tax analysis, why car-dependent suburbs generate less tax revenue than they cost to maintain, so dense urban cores effectively subsidize them. It is part of a Strong Towns series.

FortNine looks at the data on why newer pickup trucks with tall, blunt grilles kill so many pedestrians, cyclists and motorcyclists. It argues that lowering hood height would substantially cut fatalities.
