For what little it’s worth, this is not a new discussion. When the VAX was being developed (1980) there was a move to eliminate violent and sexist terminology.

Dne 18. 06. 20 v 14:27 Mark Rotteveel napsal(a): Depending on the context, other usable terms to replace master could be agency hive primary conductor captain schemer guide Oh dear! Master is a "title" linked to top authority and professionalism in specific area (context) - like Master of ... Arts etc, it's not necessarily linked to power, or God forbid the slavery. Equivalent word/term/title exists in all languages. Hence using such term in any context to refer to top authority in given area is simple, clear, and easily translated to other languages (which is the primary reason why it's so popular). And for slave: "Slave" was an unfortunate choice as it has only one "hard" meaning in english. For non-native english speakers, it's natural to translate "slave" to word equivalent to "subordinate" in their native language, hence they mostly don't see it offensive as native english speakers, and for many the "slave" word may be pronounced more easily than "subordinate" or other replacement. But this cleansing crusade has nothing to do with masters and slaves, neither with common good. It's just frustration of people weaponized and redirected to wrong target, as eradicating words from our vocabulary achieves nothing positive for our societies. It will only shift us toward '84 where Hate is Love, Peace is War etc. Slaves and slavery is deeply part of our lives, we are slaves of our habits, many work conditions are pure slavery, parents can enslave their children physically and emotionally etc. and eradicating the word will not change that. In fact, as human mind needs words and images to operate, loosing words can (over few generations) effectively cripple our capacity to think about affected topics, which in turn will limit our capacity to solve linked problems. regards Pavel Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
[Firebird-devel] Unnecessary expression evaluation?
Hi! Some expressions, for example arithmetic, concatenation evaluates the second argument even when the first is NULL. In ArithmeticNode there is this (old) comment: // Evaluate arguments. If either is null, result is null, but in // any case, evaluate both, since some expressions may later depend // on mappings which are developed here What are these "mappings"? Can this evaluation of second argument when the first is NULL still be necessary for any reason?

What is the difference between "master" and "owner"? Owner means "a person who owns something : one who has the legal or rightful title to something", and this is a neutral term. While master (specifically in the master/slave context) is "an owner especially of a slave or animal", and this is about the absolute power-relationship that dehumanized other people (ie slaves), and literal control over life and death of other humans. So while a master is a specific type of owner, the term owner itself does not have the same meaning as master.

My English is bad so sorry if it have wrong maining. In my humble opinion this discussion is usless. E.g. rasism is against people. It have no corelation with software/hardware. And there must be violence against people physical or mental. But this have not relations to maschines/software. Master/slave is technical thing. It is in any electronic with magistral. And think about. If i write white people i am rasist or only when i write black people? I suppose in non of this. There must be some violence against people.

It only shows that you don't care about what others think about you or the project! If you don't care about the terms, then you can simply be quiet, let the people who do care, discuss and work on the changes. You should understand that while certain terms may offend certain people, vigorous actions that are clear Overton Windows shifting the society toward one controlled by minority of One Truth Owners may offend certain people as well. If you would be raised in Europe (especially central or eastern) in last century (or another place ruled by One Truth Owners), you would not be so surprised. You should also understand that changing terms is not the issue on itself. The problem is *why* we should do it. If the reason is primarily to follow others to keep their acceptance and not get eventually punished or excommunicated, then as classic wrote: "something is rotten in the state of Denmark". So, if you want to change certain terms to more precise ones in sake of clarity, be my guest.
