Just a quick note for hosting a DB on a pi (or anything that uses SD cards for the OS), SD cards fail with some regularity, so I strongly suggest getting an NVMe board with a stick of SSD memory to store the actual files, because it's much more reliable long term for data integrity. SD cards support reading large amounts but writes wear them out more quickly.
You can find great cases that come with the boards (but not the SSD, however that's very easy to find separately).
When I was at school (UK) there was a German girl and a Swiss girl talking in German and one of them said "Scheiser" really loudly, the teacher turnes and glared at them and slowly they realised why and had to apologise to the teacher, as they hadn't really thought that while he couldn't understand, he still knew the swear words!
Wasn't a big deal was just funny and everyone laughed (incl teacher), needless to say they were a bit more cautious after that.
I've seen these sorts of things at subway exits/entrances in airports, where you have carts for moving lots of bags at once. There might also be shops nearby with shopping carts that people have tried to take on the escalator in the past.
I'm not Korean(perhaps someone familiar with the place might be able to offer more insight), just offering some possibilities, but it's difficult to know without more context.
Could be a cheap can opener, similar to the ones used in military ration packs. It is lacking the typical fold out sharp blade so perhaps not, or it's been adapted from that tool by cutting the blade part off. Pic of the tool below
I thought so too before moving here, but there's two cities, and a lot of empty space (in the north in particular) with lots of towns and villages, it's not like Monaco or the Vatican City in that regard.
That being said, it's still all very close together, you can drive from the northern most point to the south in about 1.5-2 hours.
The funniest thing I've learned about the geography is that there is a North/South divide where people from either don't trust people from the other.
Schengen - the village in Luxembourg where the Schengen Agreement was signed. The population was 5196 in 2023 (appears to be the last census quoted on Wikipedia) and the "Schengen Area", covered by the agreement represents 450m people.
I'd never really thought about until now, but do Chinese (specifically mandarin speaking) 3 year olds use Ma in place of the English speaking equivalent of "why" (repeated ad nauseum until the adult being questioned snaps!)?
One of the most wholesome things on the internet is being able to see all the trans joy in spaces such as these.
Good for you, and may all trans people find such joy :)
