E47: Oops! The Winston W. Royce Story

Mar 14 2025 26 mins

In 1970, Winston W. Royce published a paper “Managing the Development of Large Software Systems.” Later authors cited it as the justification for what had come to be called the "waterfall process." Yet Royce had quite specifically described that process as one that is "simplistic" and "invites failure."That's weird. People not only promoted a process Royce had said was inadequa

E46: How do metaphors work?

Feb 26 2025 32 mins

Conceptual metaphor is a theory in cognitive science that claims understanding and problem-solving often (but not always) happen via systems of metaphor. I present the case for it, and also expand on the theory in the light of previous episodes on ecological and embodied cognition. This episode is theory. The next episode will cover practice.This is the beginning of a series roughl

E45: The offloaded brain, part 5: I propose a software design style

Dec 31 2023 38 mins

In this episode, I ask the question: what would a software design style inspired by ecological and embodied cognition be like? I sketch some tentative ideas. I plan to explore this further at nh.oddly-influenced.dev, a blog that will document an app I'm beginning to write. In my implementation, I plan to use Erlang-style "processes" (actors) as the core building block. Many softwar

E44: The offloaded brain, part 4: an interview with David Chapman

Dec 04 2023 43 mins

In the '80s, David Chapman and Phil Agre were doing work within AI that was very compatible with the ecological and embodied cognition approach I've been describing. They produced a program, Pengi, that played a video game well enough (given the technology of the time) even though it had nothing like an internal representation of the game board and barely any persistent state at al

E43: The offloaded brain, part 3: dynamical systems

Nov 07 2023 25 mins

Scientists studying ecological and embodied cognition try to use algorithms as little as they can. Instead, they favor dynamical systems, typically represented as a set of equations that share variables in a way that is somewhat looplike: component A changes, which changes component B, which changes component A, and so on. Peculiarities of behavior can be explained as such systems

E42: The offloaded brain, part 2: applications

Oct 27 2023 34 mins

Suppose you believed that the ecological/embodied cognitive scientists of last episode had a better grasp on cognition than does our habitual position that the brain is a computer, passively perceiving the environment, then directing the body to perform steps in calculated plans. If so, technical practices like test-driven design, refactoring in response to "code smells," and the e

E41: The offloaded brain, part 1: behavior

Oct 12 2023 31 mins

Embodied or Ecological Cognition is an offshoot of cognitive science that rejects or minimizes one of its axioms: that the computer is a good analogy for the brain. That is, that the brain receives inputs from the senses; computes with that input as well as with goals, plans, and stored representations of the world; issues instructions to the body; and GOTO PERCEPTION. The offshoot

EXCERPT: Concepts without categories

Sep 29 2023 15 mins

This excerpt from episode 40 contains material independent of that episode's topic (collaborative circles) that might be of interest to people who don't care about collaborative circles. It mostly discusses a claim, due to Andy Clark, that words are not labels for concepts. Rather, words come first and concepts accrete around them. As a resolute, concepts are messy. Which is fine,

EXCERPT: Christopher Alexander’s forces

Sep 27 2023 14 mins

Software design patterns were derived from the work of architect Christopher Alexander, specifically his book A Pattern Language: Towns, Buildings, Construction. This excerpt (from episode 39) addresses a problem: most software people don't know one of Alexander's most important ideas, that of "forces".

E40: Roles in collaborative circles, part 2: creative roles

Sep 25 2023 45 mins

The last in the series on collaborative circles. The creative roles in a collaborative circle, discussed with reference to both Christopher Alexander's forces and ideas from ecological and embodied cognition. Special emphasis on collaborative pairs.SourcesMichael P. Farrell, Collaborative Circles: Friendship Dynamics and Creative Work, 2001Louise Barrett, Beyond the Brain: How Body
