Also, yes, master / slave is outdated. If you are developing a new product, do not use master / slave terminology. It is not appropriate for professional work product.
Daemon is troublesome in many households for young hackers, which I don't advocate changing; this just makes me a little sad.
Killing, I have no problem with, but I'm an American. If I were, say Austrian, I might prefer terminating processes.

The whole point of PC (political correctness) is to take power away from racists, sexists and other -ists by demonizing words and concepts. I think this has obviously gone too far in many areas. For instance, people should be able to discuss slavery, racism, violence, etc in a grown-up environment without fear of undue reprisal. If someone is still an actual racist shithead then they deserve the consequences of their free speech.
Speech and names should be respectful, especially in the professional arena. Being witty is fun, but causing real pain is not. Some people are killjoys who pounce on every troublesome or ambiguous potential "trigger" word. Some people are assholes who don't believe words can cause real pain - or worse - enjoy negging, controlling, and demeaning.
Personally, I tell horrible jokes and say mean things about people pretty often, but only verbally, and only to small audiences who take them in the manner intended. I'm sure I say hurtful things in amongst the jokes sometimes, but I also try to show respect in most of my dealings as well.
