Don't Pray To The Duck

I think every programmer out there has heard of rubber duck debugging. If you have not heard of it, I will cover the basics here.

I want to share with you some very important advice a co-worker gave to me when I pointed out that talking to him seemed to help more than rubber duck debugging, even though I realized what I was doing wrong while talking to him before he provided me any feedback.

That’s when he introduced me to the concept: Talk to the Duck, Don’t Pray to the Duck.

Something about walking through the problem verbally makes it easier to spot errors.
