Notes so far
Reading the 20th-anniversary edition. So far it reads less like a tutorial and more like advice from a senior engineer who has seen every shortcut backfire.
- DRY is about knowledge, not just code — duplicated decisions are the real danger.
- Tracer bullets vs. prototypes: build something thin but end-to-end and real.
- Treat plain text and the command line as long-lived, leverageable tools.
Will update the rating once I finish.
