Greg Wilson surveys what empirical research actually shows about software development, why we believe it, and how to share that knowledge more widely. It covers evidence on practices such as TDD and design patterns.

A short clip of the Super Mario Bros 3 proof-of-concept PC port built by id Software's founders to pitch Nintendo on a PC version. Nintendo passed, and the same technology led to Commander Keen.

A short EDS television commercial that shows an airplane being built while it is in flight. It is an early use of the 'building the plane as it flies' metaphor.

Half as Interesting explains why airlines flew empty 'ghost flights' out of Heathrow to keep their landing slots under use-it-or-lose-it rules.

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.

Robert Wills of TNMoC explains the Apollo Guidance Computer hardware and software, then walks through the Apollo 11 landing procedure step by step, including the 1202 alarms.

A DevGAMM talk by Jonathan Blow arguing that civilizations can lose technological capability and that software quality is already deteriorating. He discusses how knowledge fails to transfer between generations.

Casey Muratori's long talk arguing that modern software has ballooned to tens of millions of lines because of hardware and OS diversity. He proposes a stable ISA for entire system-on-a-chip packages and recalls when games shipped with their own boot disk.

John Ousterhout, Stanford professor and creator of Tcl, presents the ideas of his book A Philosophy of Software Design in a Talks at Google session. He covers managing complexity, deep modules and interfaces, and what he teaches in his Stanford software design course.
