Lo que pasa al copiar código sin revisarlo

Muy bueno lo que se explica en Nissan app developer busted for copying code from Stack Overflow:

Copying and pasting code from the internet is one of the biggest open secrets in computer programming.

A developer working on the NissanConnect EV mobile app just got caught red-handed when a verbatim Stack Overflow answer showed up in the most recent app update.

But the fact that a line of code copied from the internet somehow made its way through the quality assurance process (there is a QA process for Nissan apps, right?) and deployed as an update — to an app that manages a car nevertheless — doesn’t give me a ton of confidence to Nissan or other connected cars in general.

So the lesson here? Never, ever copy and paste code from the internet you don’t understand. I repeat: never copy and paste code from the internet you don’t understand.
