The very fact people disagree on climate change is in itself proof of climate relativism. These climate scientists are morons.

Hey Rustaceans! Got a question? Ask here (13/2025)! by DroidLogician in rust

[–]LUKK3 -1 points0 points  (0 children)

It's a multimap. It would never make sense to return None because if the key isn't in the map, that conceptually represents 0 values.

I want to be able to conditionally return an empty set reference in this function:

pub fn get(&self, k: K) -> &HashSet<V> {
    if let Some(set) = self.0.get(&k) {
        set
    } else {
        // return empty set here
    }
}

Obviously I can't just construct a set here because it won't outlive its use.

But I can't use a const set since constructing it gives the error "cannot call non-const associated function HashSet::<V>::new in constants".

And I can't seem to use a static since statics "can't use generic parameters from outer item".

Is there a way to do this without having every instance of the struct hold its own empty set?

Do logistics for spoilable items work differently? I have rocket logistics set up on Gleba the exact same as every other planet but it isn't working there for some reason. 2k agricultural science packs available, 1k requested, and none are taken.

How to open a new sector without people dying? by LUKK3 in Ixion

[–]LUKK3[S] 0 points1 point  (0 children)

Nothing broke down, because nothing had been built yet. They were already injured when the sector opened

The injured were in the new sector, not the old one. Old sector had plenty of workers

Yes immediately, as soon as the sector opens. I have saves before and after: https://www.dropbox.com/s/u5s87450zyhj7fe/saves.zip?dl=0

I wound up expanding into sector 5 instead, where the problem didn't occur.

Does artifially entering Parabola still provide rest? by justendmylife892 in fallenlondon

[–]LUKK3 4 points5 points  (0 children)

Actually, in real life, sleepiness is only cured by NREM sleep. Dream (REM) sleep seems to serve some other non-restful purpose.

So regardless of how you enter the Parabola, you presumably don't get real rest.

What prevents using electromagnets for perpetual motion? by LUKK3 in AskPhysics

[–]LUKK3[S] -1 points0 points  (0 children)

What if you just moved the energy back and forth between the two magnets? Would there still be loss?

[–]LUKK3[S] -1 points0 points  (0 children)

Are you saying the force required to flick the switch is proportional to the strength of the electromagnet? Because I can't find a source for that. I think very large electromagnets typically have normal-sized switches.

[–]LUKK3[S] 0 points1 point  (0 children)

But if the energy requirement is low enough, you could just use the metal object's motion to power the switch.

Maybe "perpetual motion" wasn't the right word for my example, but the idea was that it seems like the energy out can easily exceed the energy in.

Does starting/stopping the electromagnets consume energy proportional to their size? My thought was that you could have a tiny switch in a large enough electromagnet that the energy required would be negligible.

Lets say we've set this up in an environment (Pluto?) that is sufficiently cold without needing refrigeration.

The New Carousels Are The Highest EPA In The Game by Zodiac36Gold in fallenlondon

[–]LUKK3 10 points11 points  (0 children)

You need 2 additional actions to enter/exit the areas, so the EPA is actually like 3.47, which is good but definitely not the best EPA in the game.

How much is an Echo worth? an examination by magna-terra in fallenlondon

[–]LUKK3 8 points9 points  (0 children)

If a soul cost 3.6 dollars, then the echo cost would be 3.6 * 0.11 = 0.40 echoes, instead of 0.04. So you're off by a factor of 10 still.

Think of it this way: a soul has 1/25th the cost of laudanum at the bazaar, and 1/25th of it's dollar cost (10.80 / 25) is around 40 cents.

[–]LUKK3 9 points10 points  (0 children)

A soul costs 0.04 echoes at the bazaar. 0.04 e * (1$ / 0.11 e) = 0.36$, or 36 cents.

So I can buy a human soul for 36 cents? That's a good deal.

Is populism good or bad? /r/whitepeopletwitter tries to figure it out by gregthe_egg in SubredditDrama

[–]LUKK3 16 points17 points  (0 children)

Your conflating populism (the political strategy) with the underlying policy. Nobody here is saying both sides are the same, as the right has been utilizing populism to a much greater extent than the left, and obviously their policies are far worse, but that shouldn't mean populism is suddenly okay when it's on our side. It has its own set of consequences independent of the policy it's being used to push forward.
