DRY = Don’t repeat yourself
This is silly. Everyone knows that DRY is telling you that if you do the same sequence of mouse clicks three times in a row, you should spend the day writing a script to automate the task instead of quickly finishing what you were doing by doing the same sequence of clicks a fourth time. If you are supposed to apply it to the code you write, then there’d never be boilerplate-heavy languages like Java.
I thought I was clear enough there that I could get away without a /s
at the end. Of course the real meaning isn’t it’s a really good idea to spend a day automating four mouse clicks you only need to do one more time.
