I spend my days scraping and reverse engineering various embedded legacy systems and a recurring thought is "Who is the braindead person who specified or implemented this?" Then I realize those bad technical decisions most of the time end up in production due to business concerns. Often they show a clear misunderstanding of how the underlying tech works, i.e. inexperience. Only rarely those bad designs seem to stem from pure incompetence. That said, my frustration still gets converted into not-so-polite comments in the source code the culprits will never see.
