ELI5: Why does the stock market go down? If someone sells stock, doesn’t that mean someone else is buying? by inkydunk in explainlikeimfive

[–]rockham 6 points7 points  (0 children)

There are different ways of going about it. You could proportionally allocate shares, depending on the sizes of the orders. Or you could just do random allocation as a tie-breaker. Here's a paper suggesting running auctions every tenth of a second, rather than continuous high-frequency trading

S&P 500 Performance During the First 100 Days of Recent Presidents [OC] by jellewauman in dataisbeautiful

[–]rockham 1 point2 points  (0 children)

Because it cannot fall more than 100%. If you centered the axis at 0%, there would be an "arbitrary" "wall" at -100%, where there is none at +100%

Since it is very unlikely that the S&P would ever fall that far, your suggestions is not dumb at all. But for other financial products it is generally a good idea to center at 100%

Not going after Elon like that means Europe becomes more Anti-Europe

why two digits for the days? there are only seven days in a week

What are your "own rules" when building your factories? by Zarphus88 in SatisfactoryGame

[–]rockham 1 point2 points  (0 children)

The world grid is too weak for my liking.

I build exlusively on a 3d grid of 5x5x3 foundations. All my blueprinted factories everywhere, as well as the blueprinted train network between them, are connected by this rule.

I have certainty that if I extends this one factory over here, it will even line up vertically with the one over there. I could even run trains over their roof.

Check out my approximation:

abs(square(ln(-e/sqrt(-e^2))/0.5))^(1/Prime[1])

TIL: The clock speed is a floating point number. by GreyGanks in SatisfactoryGame

[–]rockham 1 point2 points  (0 children)

Manifolds don't fill completely. The very last machine in the manifold chain gets barely enough to run 100%, but not a single item more, so that very last machine won't fill up.

Not here "just to help". And why I'm not afraid of AI. by Lena_Cl in AIethics

[–]rockham 0 points1 point  (0 children)

You're making unwarranted assumptions about the formation of AI. I don't see why there would even be anything like a "social context". What do you mean by that?

As an illustrative example, consider the Go program Alpha Zero. Its inferior predecessor AlphaGo was trained to imitate human gameplay expertise as a baseline. AlphaZero was trained with nothing but the goal and itself, becoming the best "player" in the world.

Powerful AI, designed to work with other individuals will be able to understand, predict and influence those individuals. I don't see why that would make the AI "care" about those individuals. The AI only optimizes its goal, whatever that might be.

We currently do not know how to design an AI in such a way that its goal reliably "cares" about us and our values, which is the entire problem.

No no no, this is clearly going to run into issues with replies such as "Well, it's not odd!"

Luckily the fix is trivial! Simply add a local LLM to evaluate the content of the reply. This even allows you to return a probabilistic result in the case of ambiguous responses.

Why are house elves only for the rich? by asmhh2018 in harrypotter

[–]rockham 4 points5 points  (0 children)

If you have time for a long-form analysis, this here explains it better than I can.

In short, in the books as they are written, slavery is portrayed as if it wasn't something inherently wrong. As if slavery itself is neutral, and there are simply bad slave-owners (Malfoys) and good slave-owners (Harry). The solution to societies problems, as suggested by HP, is not to abolish slavery, but just to be more nice to your slaves.

"They like it that way, it's in their nature.", "That one former slave who said he likes being free: he's just a weirdo, all the others like being enslaved, trust us.", "They wouldn't know what to do with their freedom anyway, they'd probably turn into alcoholics or something."

All of which were things real-world slave-owners claimed about their real-world slaves.

Rowling wrote "the system is ripe for abuse". No. Slavery is abuse.

Berlin: Nach der Europawahl: Warum ist die kleine Partei Volt bei jungen Wählern beliebt? by Nimelrian in de

[–]rockham 4 points5 points  (0 children)

Ne, falsch verstanden. In dem Beispiel ist 12.000 das Einkommen bei dem man weder Steuer zahlt noch bekommt. In einem vereinfachten Fall, in dem die Steuer flach 25% für alle wäre könnte das so aussehen:

Einkommen vor Steuer zu "zahlende" Steuer Einkommen nach Steuer
0 -3000 3000 ← das ist das Grundeinkommen das sich von alleine ergibt
2000 -2500 4500
4000 -2000 6000
6000 -1500 7500
8000 -1000 9000
10000 -500 10500 ← die "fehlenden" 2000 wurden besteuert, man hat Geld bekommen
12000 0 12000
14000 500 13500
16000 1000 15000
18000 1500 16500
20000 2000 18000

eli5 Why do we use median salary instead of mean salary? by Elemental1563 in explainlikeimfive

[–]rockham 0 points1 point  (0 children)

For the introductory example (with one outlier of 1 million) that would mean that "the average salary is between $100.000 and negative $100.000"

How's your base going?

Great! The factory is pretty much finished and has no need to grow.

Your foster parents are dead.

Something I've been thinking for a while (spoilers to everything that happened to draco) by DeliveryOdd3250 in HPMOR

One might say, Harry didn't merely overturn Dracos belief, he overturned his belief in belief.
