DoD Ch. 11

     Brooks begins by talking about constraints challenge the designer.  Then he talks about the different types of constraints and describes each one: Real, Obsolete, Intentional artificial, and constraints misperceived as real.  Obsolete constraints come from using old technology. Misperceived constraints are constraints that are subtle and hard to see. Brooks further explains these types of constraints as false constraints.  Then he goes on to talk about general-purpose vs special-purpose constraints. An example is designing a 100 sq-ft house versus designing a 1000 sq-ft house for a family with 2 children in NC facing north.  Brooks then talks more about these general-purpose vs special-purpose computer architecture. Brooks finishes talking about software and spatial design.
