Hi,
Understandable. For me, PDF/X is a quite reliable basis for print data.
Some preflight check makes sense, and probably I should look into what’s
possible with CLI tools.
Preflight can be dangerous. Some of these programs mess with the file
and write a new one, and then there can be errors. (We had a case long
ago where a 'famous preflighter' decided to mess with linewidths whicxh
resulted in a 20K misprint run by a publisher. Easy to backtrack to the
changes and no pity from our end (underpaid anyway).
Apple’s Preview allows to include a manual signature. I would be
surprised if that counted as a valid digital signature.
Apparently Wondershare, PDFgear, and Sejda do the same.
with all these tech companies pleasing dictators soon there is little
untainted hard- and software for me to choose from ... so i can't
check apple
I wouldn’t buy Apple any more, also MacOS is getting enshittificated
more and more, but my 2013 Mac mini is still my work computer, and I’m
more productive on MacOS than on any Linux – it’s in the details, e.g.
there’s no mark/annotation feature for files that works cross desktop
environment. There are no tools to convert these informations from
Apple’s resource forks to anything useful. There is still no good
encrypted file system for external disks that works with MacOS and Linux
(I’m using VeraCrypt, but it’s dead slow on my old computers).
i had to ditch a windows surface (now a linux tablet) because for some
reason a not bitlocked system had become one (no key of course) ... i
never encrypt pc's (only the fairphone is encrypted)
which makes one wonder: i think that for pdf some kind of check is fine
but encryption is more tricky as what about 50 years from now (even for
legal documents) ... govermements never look more than 3-4 years ahead
(btw, in todays paper: germany moved (past tense) away from big tech and
then only mentioning one 'bundeslander' having done that and nothing
about the other having reverted .. flip-flopping; no mentioning of tex btw)
I like GNOME, but KDE’s Dolphin is a better file manager, but some of
its features/extensions don’t work with GNOME…
I keep an eye on linux as fallback but it gets more bloated (even
updating server is now gigabyte downloads with seeing stuff (libs)
installed that i can't imagine making sense in a headless setup.
Anyway, I just ordered a rpi 500+ in order to see how cheap / small we
can go. Probably also a bit of making luametatex/context run faster
challenge (as it will likely run 1/3 my current laptop).
(the fastest amd tuxedo laptop i looked at is a bit out of my budget
right now anyway and the current oen still runs fine, otherwise it would
be a 6 times test setback)
(no rant)
