Episode notes
Software Complexity
- Software's primary enemy is complexity, hindering its adaptability and understandability.
- Complexity manifests as change amplification, high cognitive load, and unknown unknowns.
Unique Teaching Style of CS190
- John Ousterhout's CS190 class employs a unique teaching style.
- It focuses on iterative code reviews, guiding students through design improvements on practical projects like building text editors.
Deep Modules vs. Shallow Methods
- Deep modules, like Unix's file I/O, offer powerful abstractions with minimal complexity for users.
- Shallow methods, by contrast, expose implementation details and increase cognitive load.
