Part 1: 00:11
Alexander's definition of "living structure" and how to deal with it

Mentioned:

• My livestream lecture: Christopher Alexander: A Primer
• Alexander tells the story about objections to the Berkley development in this short video: The Application of Feeling
• Nikos Salingaro's mathematical measure of living structure is in his book A Theory of Architecture
• On eye movement in architecture, see Ann Sussman's work

Part 2: 13:18
Describing "life" as a function afforded by form, connection to Husserl's fundierung and Gibson's notion of affordances

Mentioned:

• Stuart Kauffman's Screwdriver Problem
• On the idea of a "hire" in Job To Be Done Theory, see Competing Against Luck for an introduction
• Fundierung, function, and facticity are explained in Gian-Carlo Rota's 1989 paper Fundierung as Logical Concept
• The book I meant to recommend is Gian-Carlo Rota's Indiscrete Thoughts, not The Star and The Whole (which is also interesting but not written by Rota).
• J.J. Gibson's book on affordances: The Ecological Approach to Visual Perception
• Alexander's 15 Properties are explained in The Nature of Order Book One.

Part 3: 23:47
What it "is" versus what it "does", three levels of software: the backend, the interaction layer, the layer of life. Music software example. Basecamp concept example.
