Weekly Reflection #24 - Conceptual integrity
|
Each week, I share one insight. One piece of wisdom. One question to reflect on. (and a little Lagniappe) InsightI have to come clean. I've been putting off one of the most-recommended books in our field for years: The Mythical Man-Month. I can't believe, after co-hosting Book Overflow for almost two years, we hadn't read this yet. Martin Fowler's recent post finally got me to take the plunge, and boy was I missing out! My favorite idea in the book is conceptual integrity. Conceptual integrity is the property of a system feeling like it was designed by one mind, even when many hands built it. In an era of agentic AI tooling, it's so easy to dial this one in and lose sight of it. It's far too easy for LLMs to be locally capable but globally incoherent. It makes the architect's role, the keeper of conceptual integrity, more important than ever. Never vibe the conceptual integrity.

The ritual categorically removes a potential source of stress from my week, all from a simple little habit. Wisdom A schedule defends from chaos and whim....
Each week, I share one insight. One piece of wisdom. One question to reflect on. (and a little Lagniappe) Insight Tony Fadell tells a story in his book, Build, about his time at General Magic. The place was filled with brilliant people, but they had no shipping rhythm and no external pressures. Years passed and the work drifted, missing chances to prove it out with customers. He argues that the way to combat this is with "heartbeats and handcuffs". Heartbeats are an internal cadence....
Each week, I share one insight. One piece of wisdom. One question to reflect on. (and a little Lagniappe) Insight No matter how much weight I can lift, I always start with an empty bar. Ten reps. A focus on perfect form. A kinetic meditation. It reminds me to leave my ego at the door. It lets me listen to my body. How do I feel today? Am I creaky? Am I great? Then I put in the real work. I progressively load up the bar and push myself to grow. The same goes with software. Don't skip the...
