Yeah, and I assume future me will be even dumber than present day me, so I try to make it really easy for him to find out what he needs to know.
Another good tip is to put timestamps and increase the length of your bash history. That way when I log in half a year from now I'll know what I was up to.
All of your issues can be solved by a backup. My host went out of business. I set up a new server, pulled my backups, and was up and running in less than an hour.
I'd recommend docker compose. Each service gets its own folder inside your docker folder. All volumes are a folder in the services folder. Each night, run a script that stops all of them, starts duplicati, backs up to a remote server or webdav share or whatever, and then starts them back up again. If you want to be extra safe, back up to two locations. It's not that complicated if it's just your own services.
I'll have you know my neck beard is thoroughly covered by the rest of my beard.
They heard you liked birds, so they put birds on your birds so you can birdwatch while you birdwatch.
Whoever wants to info dump on this thing, now is your time to shine. There are cars decades older than this thing, so I'm really interested to know what the deal is with it. But I know if I look it up I'll go down a several hour rabbit hole and not sleep again tonight.
There's no forgetting where I have something hosted. If I ssh to service.domain.tld I'm on the right server. My services are all in docker compose. All in a ~/docker/service folder, that contains all the volumes for the service. If there's anything that needed doing, like setting up a docker network or adding a user in the cli, I have a readme file in the service's root directory. If I need to remember literally anything about the server or service, there's an appropriately named text file in the directory I would be in when I need to remember it.
If you just want a diagram or something, there are plenty of services online that will generate one in ASCII for you so you can make yourself a nice "network topology" readme to drop in your servers' home directory.
If you ever feel like an imposter just walk into a busy public bathroom like at Walmart or a big gas station. Do your business. Wash your hands, and let the commotion, lack of personal space, and horrible air dryer noise shatter your soul and know that you're autistic.
Landlords are familiar with utility install people and how unpredictable they can be. Even if they get mad, this will put the blame squarely on someone else so it's probably a good option for you. "I dunno why he put it there. You know how utility guys are. It's the only place he'd put my hookup."
Second this. Landlords don't want their stuff screwed up by inexperienced tenants' diy projects, and they don't want to pay for something they think it's unnecessary. I'd get an estimate for a pro to do it (could be a guy off Craigslist or whatever, just someone who does this for a living) and then just ask the landlord if they'd be alright with you paying to get it done. They'll probably want to know exactly what they're going to do, and they'll likely say yes, especially since you say they already have coax running through the house.
I'm not familiar with that one, but I soon will be.
This is why voyager had so many shuttles. Once they started beaming the poop into space instead of shuttles they could use their entire stock of poop shuttles as normal shuttles. Bit of an extravagance for the delta quadrant, really
If you have humidity problems in your bathroom, get a small electric dehumidifier. They're less than 30 bucks and they'll fix it right up.
