dependency inversion

Part one of an American Airlines training video presented by Captain Warren VanderBurgh on automation dependency. It grew out of a program on wake turbulence avoidance, and this restored version has the audio cleaned up.

Robert C. Martin (Uncle Bob) presents the principles of Clean Architecture, covering dependency direction, boundaries, and why frameworks and databases should be details rather than the center of an application.

CityNerd's Ray Delahanty tallies the personal costs of driving and then the externalities that car dependency imposes on everyone else, with numbers for each. It is an urbanist case that driving is heavily subsidized and costs society far more than drivers pay.

A re-upload of American Airlines captain Warren Vanderburgh's 1997 presentation warning that pilots who over-rely on cockpit automation lose manual flying skills and awareness. The uploader adds context from his own flying.

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 how small pockets of shops and restaurants inside residential Dutch neighbourhoods create liveliness and help reduce traffic. It argues this kind of mixed-use design has been illegal in most of the US and Canada for a century because of zoning, and should be brought back.

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.

Fons van der Plas introduces Pluto.jl, a reactive notebook for Julia that tracks references between cells and re-runs affected cells when code changes. The talk was given at JuliaCon 2020.

Stuart Sierra presents the Component library for Clojure, a way to manage stateful services like database connections and thread pools without global mutable state. He draws on both functional and object-oriented principles.

ACS Reactions investigates why Mexican Coke, supposedly cane sugar sweetened, tested as having glucose and fructose, explaining that sucrose breaks down in acidic soda.

Not Just Bikes looks at the cancelled plan to spend over $200 million widening Wonderland Road, a stroad in his hometown of London, Ontario. He asks whether the cancellation marks a turning point away from car-dependent development.

Not Just Bikes reflects on five years in the Netherlands and tours small towns and cities, from Haarlem to Veenendaal. It argues that good urbanism with walkable streets, bike infrastructure and transit is found almost everywhere there, not just in Amsterdam.

Stuart Halloway's satirical talk describes how to protect yourself from industry change by spreading complexity through systems while following idiomatic practice. It uses this inversion to catalog software design anti-patterns.

Scott Wlaschin demystifies functional programming terms like monads, monoids, functors and catamorphisms by showing how they fit into a small toolkit. He applies them to problems such as missing data, list handling, and functional dependency injection.

Rob Pike presents Go Proverbs at Gopherfest 2015, a set of pithy aphorisms about Go design such as 'Clear is better than clever' and 'A little copying is better than a little dependency'.
