Softwerkskammmer Leipzig: Clean Code Session "TDD"

A little recap of what I learned/refreshed at the Softwerkskammer Leipzig meetup. We watched Robert "Uncle Bob" Martin's Clean Code Episode 6 Part 1 and part 2. Quotes by R. Martin if not noted otherwise:

Programming wisdom

Classes protect us from new types, data structures protect us from new functions

High debugging skill correlates with low productivity

Another word for testable is decoupled

TDD is a prerequisite for professionalism

Legacy code is code without tests (by Michael Feathers)

Refactoring techniques

• Inline local/private functions before refactoring
• Extract code into inner class (quite commonly used by Uncle Bob)
• Do not use StringBuffer in modern Java, the compiler is smart enough
• Multiply if-statements
• Parametric loops

General education

• Theories how the moon came to be
• Ignaz Semmelweis not profiting from his radical novelty of hand washing during his lifetime

Discipline are pre-made decisions
