I haven't seen any Star Wars movie.
I started Star Trek from 0 around 2 years ago.
I had to stop at number 2 of your list. (Maybe a bit later since I still watched Enterprise...) but Discovery killed the whole thing for me. I was like... how bad it can be? It's still Star Trek... well no.
Checked out a few episodes of Picard.., I dunno. That's also not necessarily the Star Trek for me. :/
(On the other hand, Seth MacFarlane's Orville was amazing)
where I live (not Japan), trams are updated with a suitcase worth of floppy disks (and these are the more modern trams here)
welp, I'm not sitting on a tram anymore
strangely Network Troubleshooter always helped me when I was out of ideas why the network just... stopped working
tho never said the problem, things just got fixed in the meantime while it analyzed n shit and then it reported no issues :P
the overall ambiguity across all UI is what annoys me, tho maybe I'm too oldschool.
what I mean, around 15-20 years ago, the UI elements had defining qualities. borders were 3D as well as buttons. they stood up from the surface, had some 3d effect to make you instinctily feel that you can push that block. and this was consistent; things you could click on were 3d. you knew you can click on a list header, it looked like a button.
scrollable content always had a scrollbar. now it appears if you bring your cursor to the place where it should be, but you don't really know for sure is it scrollable or not.
links were blue, with the pointing finger cursor.
and things like these. Granted, oldschool UI is considered ugly nowadays, but it was functional. you opened a native app for your system, even if you never used it before, the UI gave you clues on at least how to navigate or operate the given software. it was familiar on all systems.
I don't feel there is a unified UX guide for today's computers. at a point, everyone went with their own interpretation of "modern" and "clean", caused (previously) vital UI qualities disappear. everything became "flat".
which, on its own isn't bad, of course.
Your system ate a SPARC! Gah
What does this mean? Does it has something to do with... I don't know, the Sun SPARC CPUs?
Retro tech. It's not too obscure, especially nowadays. I could talk long hours about how mind fucking blowing was the Amiga and then still how it went down on the drain... tho I just see on the other people that this isn't really the topic that will kickstart (heheh) the party.
I need to find more friends...
for Android I think Connect for Lemmy is the best around. also, it gets literally better day to day since the dev is following the app's community and fixes bugs, implements things from there super rapidly.
I'm fine with it.
I mean... you can get information accessing the database. Can anyone access the instance DBs? No. How would you know reddit doesn't log these in its database somewhere?
On it's own, it's not a problem IMO. Why would you want to show all information stored on the frontend? But, if you have to investigate something, it's not that bad you have stuff in your database that can help it.
Granted, if an admin is a shitface, they can look at these information. And then...? Make fun of downvoting people? Go to other instance and that's it.
My first guess would be filtering out illegal content is something that the operator/admins of the given instance have to take care according to the law of the country the server is hosted in.

back in the XP days, I used a software called "Unlocker" just for this problem. It probably still exists, I don't know, because since Windows 7, the easiest way to find out what process locks a file is to open Resource Monitor (Start search: resmon) and on the CPU tab, using the "Associated handles" list, you can search for the file name and see the process in question (and kill it).
So yeah, Resource Monitor is a useful tool on Windows.
