I Want To Live In A Baugruppe

Moderately true of Seattle as well (two group houses, plus some people living as housemates or whatever but not explicitly a Rationalist Group House). I'm not sure if our community is big enough for something like this but I love this idea and it would be a point in favor of moving the bay area if there was one there (that I had a chance to move into) but not one here.

I Want To Live In A Baugruppe

Hell, it's not even just the bay area; Seattle has two explicitly-rationalist-group-houses and plenty of other people who live in more "normal" situations but with other rationalists (I found my current flatmate, when my old one moved out, through the community). Certainly the bay area rationalist community is large and this sort of living situation is far from universal, but I've certainly heard of several even though I've never actually visited any.

Gah, thank you, edited. Markdown is my nemesis.

Agreed that the above won't work for all people, not even all people who say

I haven't and probably can't internalize it on a very deep, systematic level, no matter how many times I re-read the articles

Nonetheless, I find it a useful thing to consider, both because it's a lot easier (even if there isn't yet such a group in your area) than writing an entire LW-inspired rationality textbook, and because it's something that a person can arrange without needing to have already internalized everything (which mig...

Making Beliefs Pay Rent (in Anticipated Experiences)

I don't think "converse" is the word you're looking for here - possibly "complement" or "negation" in the sense that (A || ~A) is true for all A - but I get what you're saying. Converse might even be the right word for that; vocabulary is not my forte.

If you take the statement "most beliefs are false" as given, then "the negation of most beliefs is true" is trivially true but adds no new information. You're treating positive and negative beliefs as though they're the same, and that's absolutely not true. In... (read more)

Words as Hidden Inferences

Replying loooong after the fact (as you did, for that matter) but I think that's exactly the problem that the post is talking about. In logical terms, one can define a category "human" such that it carries an implication "mortal", but if one does that, one can't add things to this category until determining that they conform to the implication.

The problem is, the vast majority of people don't think that way. They automatically recognize "natural" categories (including, sometimes, of unnatural things that appear similar), and t... (read more)

Agreed. "Torture" as a concept doesn't describe any particular experience, so you can't put a specific pain level to it. Waterboarding puts somebody in fear for their life and evokes very well-ingrained terror triggers in our brain, but doesn't really involve pain (to the best of my knowledge). Branding somebody with a glowing metal rod would cause a large amount of pain, but I don't know how much - it probably depends in the size, location, and so on anyhow - and something very like this on a small scale this can be done as a medical operation t...

We really need a "cryonics sales pitch" article.

I haven't investigated selling it, but up to a certain multiple of my annual salary it's included in my benefits and there is no value in setting it lower than that value; I wouldn't get any extra money.

This is a fairly standard benefit from tech companies (and others that have good benefits packages in the US), apparently. It feels odd but it's been like this at the last few companies I worked for, differing only in the insurance provider whose policy is used and the actual limit before you'd need to pay extra.

1ike6yI just looked it up, and apparently reselling life insurance is so popular it has its own word: viatical. I expect you'd get reasonably close to fair value for it, and if you wouldn't pay fair value for it, you probably should be willing to accept fair value for it. Although I'm not entirely clear if you can resell life insurance bought by an employer.
We really need a "cryonics sales pitch" article.

Nitpick: The article talks about a rabbit kidney, not a mouse one

It also isn't entirely clear how cold the kidney got, or how long it was stored. It's evidence in favor of "at death" cryonics, but I'm not sure how strong of evidence it is. Also, it's possible to survive with substantially more kidney damage than you would even want to incur as brain damage.

We really need a "cryonics sales pitch" article.

Many employers provide life insurance. I've always thought that was kind of weird (but then, all of life insurance is weird; it's more properly "death insurance" anyhow) but it's a think. My current employer provides (at no cost to me) a life insurance policy sufficient to pay for cryonics. It would currently be given charitably - I have no dependents and my family is reasonably well off - but I've considered changing that.

0ike6yThat doesn't change the situation much, if you can sell it (or get higher pay for refusing it). If you somehow can't extract value from it (doubtful unless there are laws against selling), then it's relevant.
Wear a Helmet While Driving a Car

Speaking as a SCUBA diver, the equipment is not designed to handle high airflow (such as you need when working hard on a bicycle), so even if the air tank itself wasn't a problem you'd need, at a minimum, a heavily-adjusted second-stage (the one with the mouthpiece) regulator. Possibly a different regulator set altogether. On the other hand, one of the design considerations of a second-stage reg is that the purge valve needs to resist water pressure, including the pressure of swimming; air would generally not have that problem (and you probably wouldn't ha...

How many technologies are you aware of that don't have a harmful potential application? I mean, (electronic) computers were invented for military purposes and can enable all kinds of mischief on the Internet. Refrigeration makes military logistics a lot easier.

Crazy Ideas Thread

Orion requires quite a few detonations, though; even with a massive craft (much of which is pusher plate and shock absorbers) to absorb the impact, you have to use fairly low-yield bombs and each only provides a relatively short period of thrust. You could possibly design something that takes higher yields (especially higher relative to the vehicle mass) that would survive reaching orbit on one detonation, but it would be subjected to extreme acceleration - the kind that would crush any satellite launched thus far - and I suspect there might be too much risk of tumbling given the non-uniformity of the atmosphere.

Stupid Questions July 2015

That's worth checking (both in terms of what Apple claims, and in terms of what any relevant legal precedents claim; a hardware warranty certainly shouldn't be at risk from a software modification). On the other hand, it should be easy to "un-jailbreak" a device; just restore an un-jailbroken image onto it (for example, from a backup made before jailbreaking), and you can do so before sending the device in for warranty service. If the device is "bricked" to the point that you can't restore it, then Apple probably can't tell that it was jailbroken, either.

0Sherincall7yTangential: While that would definitely be a good clause for the consumers, it's not exactly right. I have personally caused hardware damage to multiple devices just by modifying the software. Plenty of ways to do it. There's also the case in which the device is bricked in such a way that it can't be fixed even by the manufacturer, while the hardware itself is operating properly. Though, that would likely still count as a software problem.

Creating a post in Discussion only requires "a few" points of karma; creating one in Main requires 20. I believe 20 is also required for creating a Meetup post; in most ways those appear to be treated as posts to Main (for example, up- and down-votes on them count for 10x the usual amount of poster karma).

It's probably a lot more effective to draw the water from ~10m down; the infrastructure costs are far lower, you'll probably not need to insulate the water quite so much for coastal regions (to keep it from warming en route to the surface), you won't need to pump so hard (you won't have a vertical kilometer of buoyancy for your denser-than-shallower-water to fight).

Sure, I can explain.

First of all, filter match ratios pretty hard. Anybody below a 90% is probably not worth checking unless they checked you first, below an 80% not even then. Above that it starts being more a matter of enemy ratio; above 10% is probably not worth it, above 1... (read more)

Interpreting the statement generously, ChristianKI probably meant "The raw gender ratio for the site as a whole doesn't matter, only the success rate for people in your demographic (which is partially determined by the gender ratio in the relevant demographic but is not exclusively driven by it)."

0[anonymous]7yI would count poly women having more partners than poly men as evidence in favor of gender ratios mattering. It suggests poly women are in higher demand than poly men. It's possible poly men are less willing to be poly than poly women (therefore poly men are lower supply and poly women higher supply), but that doesn't go too well with my prior of men generally desiring sex more than women on average. On 3, yes, if the OP is a 10 because of his writing, or any other combination of factors, then he'll be in high demand irregardless of the imbalance, but it's not clear that the OP would be considered at the top of the pack by other women.

Anecdotally, my success in the dating world went up dramatically when I started using OKCupid; to put it simply, it got me past the "is she even interested in dating, much less dating me?" hangup that I tended to have, and led to a lower fear of rejection. Basically, I no longer worried about whether the attention was undesirable, something that I had a really hard time telling from in-person interaction back then (I've gotten better at it; this was years ago).

That exposes the maximum surface area for combustion, I guess (the surface area actually increases as the propellant is burned, interestingly) so blowing the top would work, yeah.

Stupid Questions May 2015

Whoops, you're right. I thought the gimbaling was just on the SSMEs (attached to the orbiter) but in retrospect it's obvious that the SRBs had to have some control of their flight path. I'm now actually rather curious about the range safety stuff for the SRBs - one of the dangers of an SRB is that there's basically no way to shut it down, and indeed they kept going for some time after Challenger blew up - but the gimbaling is indeed an obvious sign that I should have checked my memory/assumptions. Thanks.

1kpreid7yWhat I've heard (no research) is that thrust termination for a solid rocket works by charges opening the top end, so that the exhaust exits from both ends and the thrust mostly cancels itself out, or perhaps by splitting along the length of the side (destroying all integrity). In any case, the fuel still burns, but you can stop it from accelerating further.

You're also talking about fundamentally different kinds of rocket boosters.

They couldn't throttle, couldn't gimbal, couldn't shut off or restart, didn't use cryogenic fuel so didn't need insulation, didn't rely on pressurized fuel so they didn't need turbopumps...

Gasoline Gal looks under the hood (post 1 of 3)

The hypothetical scenario stipulates that the illusion is perfect so long as you're driving the car. That may be an unrealistically difficult goal to achieve, but if you take its success as given, it means that the illusion really is as good as the true thing... so long as the illusion is never pierced. The problem, of course, is that with a car the illusion would be all too easy to pierce; just pop the hood. Even if the actual goal is not to drive an internal combustion car but merely to *believe" you drive such a car, one glance beneath the hood (or having once been told the truth) still means a loss of value.

Boxing an AI?

If you're in a box, then the computational resources available are finite. They might change over time, as those outside the box add or upgrade hardware, but the AI can't just say "I need some highly parallel computing hardware to solve this problem with" and re-invent the GPU, or rather, if it did that, it would be a GPU emulated in software and hence extremely slow. The entire simulation would, in effect, slow down due to the massively increased computational cost of simulating this world.

It's completely trivial to prevent it from escaping when not given help; the point in Eliezer's experiment is that the AI will be given help.

Good to know. I hadn't actually bothered to check; I just used a unique password and email address as a matter of course - but I'm glad anyhow. Of course, that doesn't guarantee they're storing the password verifier, but I certainly could go read the source myself and find out.

Of course, if I was actually concerned about the security of my account here, I wouldn't use the site at all because it's only available unencrypted. Given how easy and cheap (even free) it is to enable TLS these days, I'm honestly surprised this site not only defaults to plaintext but doesn't support encryption at all. Intercepting network traffic is easy (promiscuous mode on open WiFi, run your own hotspot with an expected SSID, ARP spoofing, etc.)

One possible solution is to use a proxy. There are a number of specialized HTTP[S] or SOCKS proxies, some of which may be ideally suited for this use or at least easily adaptable to it. The proxy I use most often is called Burp Suite, and is intended for web site testing and isn't really ideal for your use, but it could technically be coerced into doing what you want.

Preserving the actual TLS traffic including authentication and integrity is a bit of a weird/tricky thing to do. You can record it easily enough using any tool capable of packet capture, but unless you store handshake, the traffic, the symmetric (bulk) encryption key, and the integrity metadata, it will be tricky to prove any given server sent that data.

I mean, I have no objection whatsoever to confusing somebody's database of "where cbhacking is supposed to be" but if it would lead to legal hassles or similar inconveniences I'd like to know.

2Lumifer7yFrom what I understand, if your booked flight continues on and you just "get off" earlier, you're fine. But if your booked flight has a previous leg that you do not actually take, the airline may cancel the entire ticket because the first leg wasn't used.
7gwillen7ySee my comment. The airlines will cancel your membership/status for doing this, and if you have any additional legs on a ticket where you skip a leg, all subsequent legs will be cancelled. This will also interfere with routing of your checked baggage, which can affect you even if you don't intend to check a bag (if the overhead bins are full.)
0T3t7yI doubt it - this is a trick that high-volume fliers have been using for a while. That said, airlines being annoyed by it is a reasonable concern, though I don't know what they could possibly do about - forbid you from flying with them? That seems like the sort of thing that would get attention. Edit: see new posted warnings.
