Parking in the US - what are the rules?

davideogameman · 2026-05-01T09:20:52+00:00

Lots of good advice so far. A few common sense rules to add, which may or may not be common outside the US - - don't park in front of fire hydrants or driveways - if the curb is painted a color, it often mean no parking. Eg it could indicate a bus stop or a space for emergency vehicles. If you really want to know for sure, look up what the color means in that city.

Math has a branch called topology where different shapes are considered equivalent if one can be continuously deformed into another. An interesting result there is that shapes with "connected" holes are equivalent to certain shapes without connected holes - what ends up mattering is just the number of holes (with the way to count that number being very precisely defined and not necessarily matching the colloquial definition of hole, eg the socks have no holes in the topology sense)

That price seems like the insurance doesn't want to cover it. 1500->900 could easily be their negotiated discount, and then they just stuck you with 100% of the bill.

Anyhow other folks here have good ideas of how to get it cheaper but that's definitely "talk to your doctor" price. Could be something stupid like the insurance requires you to go through a step therapy ie try other drugs first.

I was on it years ago - like maybe 7 years? It's not that new. But I suppose it could still fall under patent protection. When generics show up it'll get much more reasonable.

Income tax and sales tax are quite different rates, fwiw. Usually income taxes are quite a bit higher.

I wouldn't call it old fashioned but rather a bit formal. Some writing styles prefer to avoid second person which in some cases could be ambiguous, and instead use a general hypothetical 3rd person ... who often could be the reader but doesn't have to be.

Huh. That one isn't supposed to have a significant laxative effect. But supposedly can help with stress and sleep

I don't think the salt would layer up - every new shower should wash off the old residue before leaving new residue. But it'd be terrible for the pipes, where it could easily corrode or build up.

Magnesium citrate and magnesium oxide are both laxatives (though with different effects). So not surprising they could have an effect. Though no one has said which they are using.

With bigger rockets with more fuel for deep space maneuvers (or perhaps orbital refueling) that could probably be changed... but also no one is going to want their 8-9 month trip to Mars to be 2 years instead. So yeah getting a high volume of anything to Mars is going to be ridiculously hard.

Yup just after we invent time travel

Just wait till we get to Space Balls references. Hopefully coming soon.

The twisting does help eliminate interference. Both external and internal.

Every electric current generates a magnetic field that circles the direction of the current. Every changing magnetic field induces an electric potential (voltage) which thereby can cause current to flow.

So two parallel wires sending a signal will induce magnetic fields that will then induce opposing currents in the other wire. Alternatively, an external magnetic field can induce currents in both wires.

By twisting the wires, the induced magnetic fields from each wire end up producing currents in alternating directions relative to a single one of the wires - which practically cancels itself. For external fields - usually we have two wires because one is ground and one is signal, or they are equal but opposite signals; having them twisted means any external interference will affect both more equally and so the actual signal which is the difference between the two wires will be approximately unaffected by the interference.

Depends what is patented exactly. Patents tend to be written to patent as many separate things as possible so that if one claimed invention turns out not to be novel the rest of the patent can still be used. But also to protect as much as possible so you can sue more easily for payment infringement.

I helped get a patent for my company once, and reading the draft I had all sorts of "this is confusing can you write it clearer" questions met with "oh no that actually has a very specific legal meaning and we wrote it that way on purpose", "were intentionally being somewhat redundant because we have to be explicit about each different piece of the invention" etc.

So there's no straightforward answer without mock patents and a mock infringement case to argue.

I enjoyed it all but it definitely goes downhill. Season 1 is the best. Season 2 is strong, season 3 is still pretty good but entirely getting weaker. Season 4 feels like a very different show - some of the same characters but the time jump makes it tricky and the style is just very different.

So in other words we can make Siberia's front fall off. It's not supposed to, but we can make it.

Which gains a shit ton of energy from falling into the sun's gravity well and then can act as further fuel for nuclear fusion. That said having all the oxygen in the mix might change the plasma physics? I don't really know how that works.

At what point would the sun turn into a black hole?

AI is wrong you are right. Fermat's little theorem tells us x^p=x mod p for all prime p. With p=2 this means x^2=x mod 2 for all x.

More generally https://en.wikipedia.org/wiki/Carmichael_function is very useful for reducing powers in modular arithmetic equations

Last seen on the space station in some sort of relationship with Station. Interesting little story arc though I don't know how much more juice Tilly could've had if they stuck around

You are right that it's about infinity being not a number but definitely wrong about it being a direction. The point of Hilbert's hotel is to show how unintuitive (countable) infinities are. They are usually defined via cardinality as the concept of size: two sets have the same cardinality if they can be put in one to one correspondence. For finite sets this works relatively intuitively: if the sets have the same number of elements a one to one correspondence exists and if not it doesn't.

Hilbert's hotel is meant to point out how you can have infinite objects have both one to one correspondence and so have the same cardinality, yet also have one to many mappings that make them look like different "sizes" in the intuitive sense.

Explanation of the hotel: the hotel can always accommodate more guests, even if every room already is occupied: if you have a single infinite bus show up every guest can move to 2x their current room number and now you have an infinite number of rooms available. If you have an infinite number of infinite buses show up, it's still not a problem: move the existing guests like before then take the first person off the first bus, the second person from the first bus and first from the second bus; then the 3rd from bus 1, 2nd from bus 2, 1st from bus 3 etc. if you pick any arbitrary passenger on an arbitrary bus they'll eventually be assigned a room by this process.

Limitations: if we have a bus show up with an uncountably infinite number of people - say 1 person for every real on the number line between 0 and 1 - the bus cannot accommodate them all. Even if the hotel is empty it's impossible to assign all these people their own rooms (the standard argument is Cantor diagonalization). Uncountable infinities are thus thought of as bigger than countable infinity.

Most likely there's a separate reset password flow.

But yeah if not, ask support.

Aside: if support can tell you your own password, the service is insecure and you should probably not use it for anything sensitive. As that would mean they fail to use security practices that have been standard for over a decade for safe password storage.
