I don't understand how people can write code, but be completely inept at developing software.

Take a zoom feature:

SOLUTION 0:
- Use 2 buttons
- Use 2 button listeners
- Use 2 float variables (for each button).
- Don't log anything.
- Use 3 crazy, hardcoded, constant, int literals like 66, 30...
- both buttons manipulate the same text field.
- no logging.
- Both listeners use if/else to check if the variable is within a range -- one if/else for each listener.
- Use crazy method calls to get text size.

SOLUTION 1:
- Use a slider.
- Use a single listener.
- No variables needed.
- Use a linear equation for zooming.
- has logging.
