Episode notes
Code Has Multiple Meanings
- A single code implementation can correspond to many logical interfaces, making the interface hard to deduce from code alone.
- Logical facts about code involve quantifying over all possible code changes preserving behaviors.
Prioritize Interface Stability in Reviews
- Focus code reviews on the stability of interfaces and assumptions over possible future changes.
- Experienced developers tolerate minor variations to prioritize long-term maintainability.
Refactor with Clear Abstractions
- Refactoring should alter code structure meaningfully, not just reorganize without clarity.
- Avoid 'boxing' which hides complexity; ensure abstractions have clear, independent descriptions.
