I was taking Intel x86 assembly class in this Spring, and a friend of mine, @BartuMutlu, did a mistake in a quiz section about “How many asm instructions are needed”.

After the quiz 11, I naturally said, in Turkish, a sentence that is title of this post

Emin olduğun şeyden emin olmadığından emin ol

or

Be make sure you are not sure that you are sure

I could develop other ideas with this quote, but I wanted to share only the quote.
