I was a teen in the ‘80s and I never heard the origin of “Joy Division”, just knew the band. DJs on the radio (or on MTV) back then never discussed bands’ names or what they meant, so it wasn’t easy to know about that stuff. I also never knew what “Dead Kennedys” meant although that’s pretty obvious if you just think about it. Hell, I never knew Freddie Mercury was gay despite the band name “Queen”.
I also thought Boy George was a woman, but everybody did.
I always claimed in job interviews to be good at debugging, but there are no certifications for debugging and there’s really no way for an interviewer to verify such a claim. So even though it is an incredibly important skill, companies just do not look for it. There is also the hilariously misguided belief that good coders do not produce bugs so there’s no need for debugging.
