An interview with Lorin Hochstein, resilience engineer and author. Our discussion was about how to handle a complex system that falls down hard and – especially – how to then prepare for the next incident. The discussion is anchored by David D. Woods' 2018 paper, “The Theory of Graceful Extensibility: Basic Rules that Govern Adaptive Systems”, which (in keeping with the theme of the podcast) focuses on a general topic, drawing more from emergency medicine than from software.

The follower, sensing the intention, first moves her free leg and keeps the presence of her upper body still with the leader. [...] The good leader gives a clear, unambiguous and thoughtfully-timed indication of what he wants the follower to do. The good follower listens to the music and chooses the time to move. The leader, having given the suggestion, waits for the follower to initiate her movement and then follows her." He further says (p. 34), "As a leader acting as a follower, you really learn quickly how nasty it feels if your leader pulls you about, pushes you in the back or fails to indicate clearly enough what he wants." Apologies. I was long ago entranced by the idea that walking is a sequence of "controlled falls". Which is true, but doesn't capture how walking is a sequence of artfully and smoothly controlled falls. Tango is that, raised to a higher power.

The text describes the cover image as an example of a follower's "rapt concentration" that, in the episode, I called "the tango look".
