8 Software Truths

• A poor abstraction is worse than duplicating code
• Complexity is considerably easier to add than it is to remove
• All code errors are type errors, but not all type systems are expressive enough to surface them
• Given enough time all class hierarchies are eventually wrong for new use cases
• Developers who believe they can foresee the future are more dangerous than missing business requirements
• Meetings are not for communication, they are for making decisions
• Methods that work well with remote teams don't work well with traditional hierarchical management structures
• Code metrics are an effort to abstract developer output into something a manager with no domain experience can understand
