Abstract

One rule to rule them all: Make it easier to change

All design patterns, principles, etc… are aimed to have code easier for change. Perfect / correct code does not exist, aim for code that is easy to change.

Build intuition, which is crucial for coding:

• What is the change?
  • One sentence summary
• Likely effort
  • functions changed
  • estimated time
• Actual effort
  • functions changed
  • actual time
• Observations
  • Learn anything?
• Tips:
  • handwrite, don’t type
  • ideally read aloud
  • stick then in a file and forget about them
  • start listening to your gut
