Periodic self-repetition: As a data librarian I can say that "AI" is not a matter of personal preference -- whether you like it or not, or whether you have found some use that you think is useful. It actively destroys organized knowledge, and therefore it actively destroys civilization.
Whenever someone looks for a human written text and can't find it because statistical near variants have been created and indexed, whenever "AI" "hallucinates" a reference, knowledge has been destroyed.
@richpuchalsky we feel this SO HARD this week. it is no longer possible to find answers to trivial technical questions with a web search.
we're very grateful we have a curated personal library of authoritative reference material, but a lot of key Unix ideas are socially-defined and not formally documented anywhere.... (for example, just now we were trying to remember the semantics of when chown is allowed, and the rationale for it)
@ireneista One place to look for this sort of thing is the 'rationale' sections of POSIX/Single Unix Specification, which is actually online (for now), eg https://pubs.opengroup.org/onlinepubs/9799919799/functions/chown.html
This is unhelpful for chown() because it points to V7 and V7 has what could be called 'a vague justification' in its manual page as I discovered in 2020¹ and then forgot until part-way through writing an earlier version of this toot.

@cks it's online!!!! thanks! last time we dug into that, it wasn't. we'll pull a local copy for posterity
thank you! we did eventually satisfy ourselves as to this particular question
@ireneista They sort of try to make you at least register to get access to the online version, but people keep digging up the direct access URLs (and then search engines index them so you can usually manage to find at least some version, although perhaps an outdated one).
(Or maybe they've given up the registration attempts.)
@cks @ireneista i keep direct links to various POSIX editions on my ancient unmaintained bookmarks page https://dotat.at/bookmarks.html
the links have worked for decades (modulo a recent problem with redirects)
