Check out kemono.su / kemono.party. They’re a patreon(among other subscription service) archive site that makes use of crowdsourced keys. It’ll initially look like 110% porn, but you can often find other patreons there if you search those specifically, such as those for 3d printing stls. It can sometimes be hit or miss whether they properly archive downloads, but they’re usually a worthwhile option.
To a degree, yes. As was mentioned elsewhere there is a thing called Wave Function Collapse, which occurs when a measurement is taken of a quantum system and forces the system from superposition (multiple states at once) into a single state. A measurement could be seeing it, scanning it, bumping into it, etc (not human conscious observation, that’s an old and weird interpretation and not relevant nowadays).
Before (and after as well) you actually collapse the wave function you can perform meaningful math using the quantum particles. The one way I’m familiar with is for computer calculations, which is what quantum computers are aiming for. This is basically done by canceling out certain possibilities to only allow the wave function to collapse into ways that give meaningful mathematic results.
As such, this is barely relatable to a quantum Santa which uses this nature to perform meaningful present sharing actions simultaneously using quantum superposition of a quantum system that is spread out over a very large area. Of course, basic quantum mechanics becomes statistically the same as normal physics (i.e. 10 quadrillion particles average out to one normal human), so Santa would need to be a reality bender to allow for such small chances to occur to allow a human sized being to affect a huge area… but whatever.
As someone in the Eastern US (grain of salt there), this rarely occurs but if it does it is usually when a place serves a large group (justified as the extra difficulty for serving so many people at once). If I saw this applied in another situation I would 100% consider that a tip, give them nothing, and never eat there again. If it was applied when I went in a large group I’d say it can go both ways, but I’d definitely not go back there with lots of people again because it feels like its an attempt at fleecing the customer for more than the trouble is actually worth. Alternatively I might tip less, taking the 18% into account already as a tip. Overall, I’d say it’s bullshit and a good proportion of the people I know would agree.
Hope your trip goes well
It’s mentioned in the substack article that for a single individual his calculations place the poverty line around 50k, while 140k is for a family.
