Hexadecimals speak! See what codes say and we don't even realize how comical this is!

Do you know when that error occurs in any program on the computer, be it Apple, PC, or even cell phone, and that error code 0xABC9123 and etc comes? Know that many of them do not mean anything that is in a code list, if there is one, many of them are just an illusion that there is a faithful control of what happened.

However, in addition to many being nothing, there are some who even say something, as in the case of updating the wrong firmware of an SSD, the reported error is 0xDEADBEEF, which is nothing more, literally saying, "Dead Beef", or " Something went wrong with the validation ".

Here is a list of items that you would never have imagined that this could say right in your face the mistake, and you never realized:
