Not sure what you mean by "this would require a pretty small universe".
If we live in naive MWI, an IBP agent would not care for good reasons, because naive MWI is a "library of babel" where essentially every conceivable thing happens no matter what you do.
Also not sure what you mean by "some sort of sampling". AFAICT, quantum IBP is the closest thing to a coherent answer that we have, by a significant margin.
cousin_it on I'm open for projects (sort of)Done! I didn't do it at first because I thought it'd have to be in person only, but then clicked around in the form and found that remote is also possible.
tailcalled on Blessed information, garbage information, cursed informationIt's also putting the attribute on the wrong thing - it's not garbage data, it's data that's useful for other purposes than the one at hand.
Mostly it's not useful for anything. Like the logs contains lots of different types of information, and all the different types of information are almost always useless for all purposes, but each type of information has a small number of purpose for which a very small fraction of that information is useful.
Blessed and cursed are much worse as descriptors. In most cases there's nobody doing the blessing or cursing, and it focuses the mind on the perception/sanctity of the data, not the use of it.
This is somewhat intentional. One thing one can do with information is give it to others who would not have seen it. Here one sometimes needs to be careful to preserve and highlight the blessed information and eliminate the cursed information.
bhauth on hydrogen tube transportIt can't use "air" around it for engines because what's around it isn't "air".
Oxygen is much heavier than the fuel it's used with, and you'd either need liquid oxygen (which increases costs) or pressurized tanks (which would perhaps double that mass). That's still lighter than batteries, yes, but engines are also needed. Piston engines are inefficient and/or heavy, and gas turbines are somewhat expensive.
It's not that difficult to separate water and hydrogen, that's true, but processing that much gas is still rather impractical when batteries have enough specific energy. Simply condensing it in the tube is...possible, but would increase drag, especially considering density variation issues, and you'd have to deal with getting it out of a long sealed tube without leaking hydrogen.
Also, if batteries are good enough, the cost of replacing the hydrogen alone probably makes batteries better than burning the hydrogen.
jacobjacob on Express interest in an "FHI of the West"Noting that a nicer name that's just waiting to be had, in this context, is "Future of the Lightcone Institute" :)
lao-mein on Reconsider the anti-cavity bacteria if you are AsianI can confirm that my PayPal has received the $500, although it'll be frozen for a while.
Thanks! I had a lot of fun doing the research for this and I'm working on an update that'll be out in a few days.
rohinmshah on Transformers Represent Belief State Geometry in their Residual StreamIs it accurate to summarize the headline result as follows?
(I don't know what Computational Mechanics or MSPs are so this could be totally off.)
EDIT: Looks like yes. From this post [LW · GW]:
cousin_it on I'm open for projects (sort of)Part of what this all illustrates is that the fractal shape is kinda… baked into any Bayesian-ish system tracking the hidden state of the Markov model. So in some sense, it’s not very surprising to find it linearly embedded in activations of a residual stream; all that really means is that the probabilities for each hidden state are linearly represented in the residual stream.
Besides math and programming, what are your other skills and interests?
Playing and composing music is the main one.
I have an idea of a puzzle game, not sure if it would be good or bad, I haven’t done even a prototype. So if anyone is interested, feel free to try
Yeah, you're missing out on all the fun in game-making :-) You must build the prototype yourself, play with it yourself, tweak the mechanics, and at some moment the stars will align and something will just work and you'll know it. There's no way anyone else can do it but you.

It seems to me that the problem in the counterlogical mugging isn't about how much computation is required for getting the answer. It's about whether you trust Omega to have not done the computation beforehand, and whether you believe they actually would have paid you, no matter how hard or easy the computation is. Next to that, all the other discussion in that section seems irrelevant.
