Deliberate Abstraction

- Modules hide design decisions to allow for future changes without rewriting existing code.
- Good products emerge from interactions between components, not from individual features.
- Computers are flexible because they provide primitives for many possible features, not specific ones.
- Flowchart-based designs focus on features and are rigid, making changes difficult.
- User requirements change frequently, making them a poor foundation for design.
- Inside-out design starts with a general core and builds outward, allowing for flexibility.
- Avoid excessive validation logic early to accommodate changing user requirements.
- Abstractions should increase convenience while removing unnecessary power.
- The power to create abstractions is dangerous if used incorrectly.
- Inside-out design aids modularization by focusing on fundamental principles rather than features.
