Software Construction Fundamentals
Minimizing Complexity
Notes
Minimize complexity: simple readable code, coding standards, modular design.
Anticipating Change
Notes
Anticipate change: design so future modifications are easy (parameters, encapsulation).
Anticipating Change
Standards in Construction
Notes
Standards: communication methods, programming languages, coding standards, platforms, tools.
Reuse
Notes
Reuse levels: abstraction, object, component, system. Costs: finding, understanding and adapting the components.

Reuse
Open source software
Notes
Open source: source code is published and volunteers can contribute; licences: GPL (reciprocal), LGPL, BSD (non-reciprocal).
