Scary wall of text, in the spoiler you go.
Issues
So far i only faced this threat twice (in high school), but managed to avoid it.
- First, I was selected for Erasmus+ international exchange program. But I couldn't get the answer on how many people per room there would be nor whether there would be shared showers and toilets (like one large per building bathroom).
The school's psychologist then called me into her office to ask whether I would be capable of socializing with others, and to re-think it, as our group would have to do everything together in representative manner, so I just noped out. - Secondly, we went to some national competition, and were destined to stay at dormitory for 1 night. When I found that out, I said I rather won't go. When I answered why, I was told that they would arrange for me to have a single room, so that was fine. I just stayed inside there all the time, enjoying my solitude.
At home I live with parents. I don't have my own room, but subsidize for it with WC (separate from bathroom). Since there's no power outlets, I'll take 2 power banks, laptop, USB fan, phone, earphones, and stay there for most of the day.
Unfortunately, I may not find any such alone space over there.
Eating near others is also not quite easy. Usually I'd just wait for the lunchroom to empty, and then go there. Empty table near wall, with adjacent empty tables (excl. diagonally behind). Sometimes this would mean I wouldn't get to eat, or be late for class, but that wasn't a problem for me.
At home I just wait until my parents finish.
I can't stand seeing others, being seen, and hearing others' chewing if I am to eat.
Stuff to bring
I kinda like to be always ready. My biggest concern is electronics. What all do I bring? Should I take the mini PC with me, or leave it at home with WWAN modem, and use it over Tailscale?
Should I bring RTL-SDR with me, or leave it at home with the remote mini PC and only take RSP1 clone with me?
Which WiFi router to bring? Reliable one, or the one with Wireguard that restarts every 15 minutes and bootloops eventually?
Do I take both laptops for redundancy, or just the usual ThinkPad?
If bringing my CD player, do I use disposable batteries, or also take the AA charger with me?
Do I take my DAB+ radio?
Do I bring the spool of wire that's been useful for shortwave listening?
What about a printer? I'd only trust dot-matrix for moving around, but they're expensive AF.
Hell, when I went to that competition, I even took Cisco 871W (SoHo-style) and Cisco 1802 (1RU) routers, although that was mostly as a joke (I did play around with them though).
I started with an assumption there might have been a when component to that question, but nope, apparently we're taking about 2025 and not 1995.
Somewhat amazingly though, brand new dot matrix printers - not just new old stock, but newly-manufactured units including modern USB and/or Ethernet interfaces - and even the big cartons of tractor-feed continuous paper are still readily available.
As dot matrix printers have not gone the way of the dodo, also neither have carbonless triplicate forms, which they are uniquely able to print on. Seems that's still a big selling point for these printers.
