Gauging interest for a Tokyo area meetup group

I am on vacation in Japan until the end of August, I might be interested in attending a meetup. Judging from the lack of comments here this never took off, but I might as well leave this here just in case.

Open Thread March 31 - April 7 2014

I probably have obstructive sleep apnea. I exhibit a symptoms (ie feeling sleepy despite getting normal or above average amounts of sleep, dry mouth when I wake up) and also I just had a sleep specialist tell me that the geometry of my mouth and sinuses makes puts me at high risk. I got an appointment for a sleep study a month from now. Based on what I've read, this means that it will probably take at least two months or more before I can start using a CPAP machine if I go through the standard procedure. This seems like an insane amount of time to wait for something that probably has a good chance of significantly improving my quality of life immediately. Is there any good reason why I can't just buy a CPAP machine and start using it?

So if you want the other party to cooperate, should you attempt to give that party the impression it has been relatively unsuccessful, at least if that party is human?

I don't think so. It seems more likely to me that the common factor between increased defection rate and self-perceived success is more consequentialist thinking. This leads to perceived success via actual success, and to defection via thinking "defection is the dominant strategy, so I'll do that".

Pascal's Muggle: Infinitesimal Priors and Strong Evidence

After thinking about it a bit more I decided that I actually do care about simulated people almost exactly as the mugger thought I did.

Pascal's Muggle: Infinitesimal Priors and Strong Evidence

Mugger: Give me five dollars, and I'll save 3↑↑↑3 lives using my Matrix Powers.

Me: I'm not sure about that.

Mugger: So then, you think the probability I'm telling the truth is on the order of 1/3↑↑↑3?

Me: Actually no. I'm just not sure I care as much about your 3↑↑↑3 simulated people as much as you think I do.

Mugger: "This should be good."

Me: There's only something like n=10^10 neurons in a human brain, and the number of possible states of a human brain exponential in n. This is stupidly tiny compared to 3↑↑↑3, so most of the lives you're saving will be heavily duplicated. I'm not really sure that I care about duplicates that much.

Mugger: Well I didn't say they would all be humans. Haven't you read enough Sci-Fi to know that you should care about all possible sentient life?

Me: Of course. But the same sort of reasoning implies that, either there are a lot of duplicates, or else most of the people you are talking about are incomprehensibly large, since there aren't that many small Turing machines to go around. And it's not at all obvious to me that you can describe arbitrarily large minds whose existence I should care about without using up a lot of complexity. More generally, I can't see any way to describe worlds which I care about to a degree that vastly outgrows their complexity. My values are complicated.

A Series of Increasingly Perverse and Destructive Games

How does your proposed solution for Game 1 stack up against the brute-force metastrategy?

Well the brute force strategy is going to do a lot better, because it's pretty easy to come up with a number bigger than the length of the longest program anyone has ever thought to write, and then plugging that into your brute force strategy automatically beats any specific program that anyone has ever thought to write. On the other hand, the meta-strategy isn't actually computable (you need to be able to decide whether program produces large outputs, which requires a halting oracle or at least a way of coming up with large stopping times to test against). So it doesn't really make sense to compare them.

A Series of Increasingly Perverse and Destructive Games

I think I can win Game 1 against almost anyone - in other words, I think I have a larger computable number than any sort of computable number I've seen anyone describe in these sorts of contests, where the top entries typically use the fast-growing hierarchy for large recursive ordinals, in contests where Busy Beaver and beyond aren't allowed.

Okay I have to ask. Care to provide a brief description? You can assume familiarity with all the standard tricks if that helps.

A Series of Increasingly Perverse and Destructive Games

In short, take it as a given that anyone, on any level, has a halting oracle for arbitrary programs, subprograms, and metaprograms, and that non-returning programs are treated as producing no output.

In this case, I have no desire to escape from the room.

Welcome to Less Wrong! (July 2012)

Why not stay around and try to help fix the problem?

Simulating Problems

I did read that. It either doesn't say anything at all, or else it trivializes the problem when you unpack it.

Also, this is not worth my time. I'm out.
