Indeed, I misinterpreted you in multiple ways. My model went something like "Jayson_Virissimo is currently working 60-80 hours a week on his start-up. Once it exceeds ramen-profitability, he intends to scale back his efforts to become a full-time student." How very foolish of me!

I certainly hope that I'm not confused about my word choice. I write compilers for a living, so I might be in trouble if I don't understand elementary terms.

In all seriousness, my use of the word "scope" was imprecise, because the phenomenon I'm describing is more general than that. I don't know of a better term though, so I don't regret my choice. Perhaps you can help? Students that I've seen have difficulty with variable substitution seem to have difficulty with static scoping as well, and vice versa. To me they feel like different parts of the... (read more)

A little. As your income increases, I expect your consumption to become more expensive in monetary terms, but as your business grows I expect the value of your time to increase and for your consumption patterns to become less expensive in terms of time. College is very expensive in terms of time.

I'm not saying this is a bad choice, but it is one that surprises me. I'm still interested in the answers to my questions. Do you intend to sell your start-up, have it run itself, or abandon it? It seems like those options cover the gamut (I might consider requirin... (read more)

My post didn't indicate this, but the most common source of scope is functions; calling a function starts a new scope that ends when the function returns. Especially in this case, it does often make sense to use the same variable name:

posterior = ApplyBayes(prior, evidence)
...
function ApplyBayes(prior, evidence) = { ... }

Will have prior=prior, evidence=evidence, and is a good naming scheme. But in most languages, modifying 'evidence' in the function won't affect the value of 'evidence' outside the scope of the function. This sometimes becomes confusing... (read more)

...going back to school to study computer science (if my start-up succeeds before then).

That's amusing. Usually I would say the value of the founder being present is much higher for a successful company than one that has failed. I would actually expect my freedom to pursue other avenues diminish as my success in my current avenue grows.

Do you mean that your start-up, if successful, will pretty much run itself? Or that if it hasn't succeeded /yet/, then you will feel obligated to stay and keep working on it?

Of all my flaws, I currently consider my bias to thought (and study, research, etc.) over action my greatest. I suspect that LessWrong attracts many (a disproportionate number of) such people.

Not too long ago, I lost a week of work and was able to recompose it in the space of an afternoon. It wasn't the same line-for-line, but it was the same design and probably even used the same names for most things, and was roughly 10k LOC. So if I had recent or substantial experience, I can see expecting a 10x speedup in execution. That's pretty specific though; I don't think I have ever had the need to write something that was substantially similar to anything else I'd ever written.

Domain experience is vital, of course. If you have to spend all your time ... (read more)

I don't know about you, but I can't recall 10k LOC from experience even if I had previously written something before; seeing someone produce that much in the space of three hours is phenomenal, especially when I realize that I probably would have required two or three times as much code to do the same thing on my first attempt. If by "reciting from experience" you mean that they have practiced using the kinds of abstractions they employ many times before, then I agree that they're skilled because of that practice; I still don't think it's a level of mastery that I will ever attain.

In my opinion, almost all of that 50% (that drop out) could program, to some extent, if sufficiently motivated.

A great deal of Computer Science students (half? more than half?) love programming and hit a wall when they come to the theoretical side of computer science. Many of them force themselves through it, graduate, and become successful programmers. Many switch majors to Information Technology, and for better or for worse will end up doing mostly system administration work for their career. Some switch majors entirely, and become engineers. I actually ... (read more)

I've taught courses at various levels, and in introductory courses (where there's no guarantee anyone has seen source code of any form before), I've been again and again horrified by students months into the course who "tell" the computer to do something. For instance, in a C program, they might write a comment to the computer instructing it to remember the value of a variable and print it if it changed. "Wishful" programming, as it were.

In fact, I might describe that as the key difference between the people who clearly would never take... (read more)

I've taught C, Java and Python at a university and (a little) at the high school level. I have noticed two simple things that people either surmount or get stuck on. The first seems to be even a basic ability to keep a formal system in mind; see the famous Dehnadi and Bornat paper. The second, I have heard less about: in programming, it's the idea of scope.

The idea of scope in almost all modern programming languages goes like this:

• A scope starts at some time (some place in the code), and ends somewhere later.
• A scope can start before another ends; if so,

For the record, I think programming is so measurable and has such a tight feedback loop that it is one arena in which it's relatively easy to recognize ability that far exceeds your own.

1) Code quality is fairly subjective, and in particular novice (very novice) programmers have difficulty rating code. Most professional programmers seem to be able to recognize it though, and feel awe when they come across beautiful code.

2) Code quantity can be misleading, but if you're on a team and producing a 100-line delta a day, you will notice the odd team member prod... (read more)

I like being hugged from behind...by a very small number of people. From everyone else, it's quite unwanted.

This has had an interesting effect; if someone hugs me from behind, I unconsciously either put them in a bucket of people that I like a great deal, or make myself uncomfortable by telling them "don't do that". There's an odd bit of wiggle room in there, where someone might make me like them more by doing something somewhat uncomfortable to me. If this happened more often, I would take more care to address this particular bias; I also suspect there are subtler variants that I haven't recognized (I only just realized the above while reflecting on your post).

How many degrees of freedom does your "composition of N theories" theory have? I'm not inclined to guess, since I don't know how you went about this. I just want to point out that 260 is not many data points; clustering is very likely going to give highly non-reproducible results unless you're very careful.

I agree (have had the same experience), although I argue that mustard, sauerkraut or other bitter/sour foods are better examples than coffee or beer, simply because drugs change the way we process surrounding stimuli.

This also goes some distance to explaining (in an alternate fashion) why repeated exposure to the artwork increases appreciation for it. Assuming the piece really relies on their exposure to related music, extended exposure forces people to have increasingly similar backgrounds.

Torture (not murder) is my stated objection to eating meat.

Funny. I feel the opposite way: I'm okay with dying, but don't want other people to die.

While I do tend toward suicidal thoughts, even when I'm feeling pretty great the idea of my life continuing is at best of low value. I would hate to die because I know it would hurt lots of people that I'm close to, and I'm also averse to the pain of the process of dying, but nonexistence is generally an attractive concept to me. If I could get away with dying in a manner that didn't hurt me or others, I probably would.

On the other hand, I would be and have been very pa... (read more)

I'd like to weigh in on this, agreeing with pjeby. I joined beeminder, am enjoying it and expect it to be of great use to me. I don't care even a little where the money goes. The amount is a penalty to me, and I like the way it is automatically set. If the money allows you to focus more on improving beeminder, that's great. If it ends up making you rich, that's just evidence you're providing a valuable service.

I had thought the solution was very simple before you pointed this out. With some difficulty I improved my solution to O(log(log(n)) * log(n)), and it took quite a bit more time for me to get completely constant sized stack frames.

I suspect most people initially come up with the O(log^2(n)) solution and jump next to the O(log(n)) solution without getting stuck in the middle there, but I'm curious if this gave you any problems.

I'd imagine weird timing and chemical interactions being used by the brain as it is an adaptable system and might be able adapt to use them if they turn out to be helpful.

Human designers have every reason to work very hard to make sure they understand their own designs and that they are free from weird issues. Chips aren't designed [by humans] to have strange EM interactions, but sometimes they do anyway and that occasionally gets exploited---not often though. On the other hand, evolution has no such motive, so I imagine that weird edge cases are vastly... (read more)

Thank you for posting this. I want to do almost exactly this, and set up another task running that will zip up all the images and send them off to my referee.

Unfortunately, I haven't gotten this to work. I'm not very familiar with cron, and I don't know how to debug it. My script works as intended when run manually, but halts (dies? I don't know) when run from cron (at import). I haven't managed to get any error reporting, either by redirecting the script output or the import output. I also haven't been able to get import to run directly from cron, even by using absolute paths and no variables. I suspect these are problems you haven't run across, but if you have, I'd appreciate your advice.

I agree that this scenario is pretty unlikely; it seems at least possible if there was a high-level policy change that hadn't caught up to military funding and structure, but made active troop deployment very unlikely. Your second to last paragraph disagrees with this; does the US military really shrink that much when we have fewer wars going on?

China seems much more the model of a country with a large military that rarely is deployed, and they do seem to match your description; lots of manual labor, disaster relief, building infrastructure, etc., with les... (read more)

It didn't; I'm sure RSS also broke during the site transfer. I re-subscribed, and I suspect everything will work again. The re-subscription at least retrieved your two current posts. I really did find your earlier writings interesting and enjoyable. I'm not sure I necessarily need them reposted (I wouldn't classify them as reference material for re-review), but more like that would be appreciated.

I've heard that blues originates from a dirtied-down version of swing; at least, I think it's genesis is later. I just got back from an all-weekend blues workshop. Campbell and Chris were two of the instructors, and you can get some idea for what it looks like from the videos on their site. You can see that competition blues often looks a lot like (competition) lindy; maybe a little more varied, but a lot slower, fewer lifts and generally lower energy.

In practice (when dancing for a partner rather than for an audience), blues is generally much smaller and ... (read more)

I'm really not trying to be obtuse, but I still don't understand. The other possibilities don't exist. If my actions don't affect the environment that other agents (including my future or other selves) experience, then I should maximize my utility. If, by construction, my actions have the potential of impacting other agents, then yes, I should take that under consideration, and if my algorithm before I see the money needs to decide to one-box in order for the money to be there in the first place, then that is also relevant.

I'm afraid you'll need to be a li... (read more)

Is this a MWI concern? I have observed the money with probability 1. There is no probability distribution. The expected long-run frequency distribution of seeing that money is still unknown, but I don't expect this experiment to be repeated, so that's an abstract concern.

Again, if I have reason to believe that (with reasonable probability) I'm being simulated and won't get to experience the utility of that money (unless I one-box), my decision matrix changes, but then I'm back to having incomplete information.

Likewise, perhaps pre-committing to one-box bef... (read more)

I was feeling uncomfortable about that myself.

In all likelihood, I shouldn't be using probability at all, because probability theory doesn't capture cause and effect well. Thinking back, what I should have said is just that rationalists are more likely to adopt polyamory than polyamorists are likely to adopt rationalism. The actual ratios of each are less relevant.

I followed you until

I'm acausally trading with an entity other than Azathoth.

which entity are you trading with? We haven't gone back to talking about Prometheus, have we?

I might like to increase the number of meme-similar persons in my universe, but I don't really care about meme-similar persons in universes that can't influence mine. Even this is something I feel relatively weakly about. It's also just a personal difference in values, and I can reason pretending I share yours.

a very large swathe of the poly community is of a new-age and/or neopagan bent

Ugh, agreed.

I think P(newage|poly) - P(newage) > P(rationalist|poly) - P(rationalist) > 0.

I also think P(poly|rationalist) - P(poly) >> P(rationalist|poly) - P(rationalist), which is why we see it as a Common Interest.

As an aside, I've been reading your blog since (I think) before you joined LessWrong; like Wei Dai, you're one of the connections I've made to a different community that has appeared here. I usually read it through RSS, which I think broke. You also appear to have abandoned your earlier blog posts?

it really seems like she was just doing it wrong.

No, this is true. However, I would like to stretch your analogy a bit:

Some people are natural dancers, and don't really encounter the problems you're describing. Some people just know they want to dance, and deal with them.

The person in question is more of the former. In dozens of relationships she's never acted jealous before (I've known her for 10 years). She's never seemed to have an issue with it. This time, the first time I've seen her act jealous, she rejected the notion that jealousy could be the s... (read more)

and even people who are good at it and enjoy it will get hurt doing it from time to time

This I think is true. The woman in question does polyamory well, and has for a long time, and in my opinion should continue to for her own happiness. However, she definitely wasn't doing it right at that time. To my knowledge, it's the only problem she's had that has stemmed from her.

Your point is well taken. Not only do I not have children or dependents, and not only am I still somewhat in "grad student mode", but I plan on eventually going back to school, so I don't really intended to leave that mode before then.

In fact, I probably have an even more extreme form of this condition. I've never been too bothered too much by signaling low status, but I've actually been pained when I signal high status. My first (and only) car bothered me because while I bought it extremely cheaply, it was still in good shape. I feel like I ough... (read more)

If you one-box, then it's likely that in the overwhelming majority of universes you do exist.

This is incorrect, but I understand the spirit of what you're trying to say (that the number of universes that I exist in is overwhelmingly larger---no matter what, I exist in an infinitesimally small number of universes).

Regardless, this interpretation still doesn't make you cease to have ever existed. Maybe you exist less, whatever that means, but you still exist. Personally, I don't care about existing less frequently.

Lastly, do you think this interpretation ... (read more)

Wow. This actually makes sense, but if this was the intention, nothing in the original post or any previous comment revealed this to me.

So, if the problem is rephrased as: "You might be in Prometheus' simulation, aiding him decide whether to create the real you..." (especially not telling me how many times Prometheus runs the simulation) then I can see the potential utility of doing as Prometheus wants.

I personally don't derive utility from the opportunity to be created in another world, or in the "real world", but I think many people m... (read more)

It is; I misunderstood, although I don't think your notation is blameless.

Basically, in the sequence triangle->square->pentagon->... appears to be a process that approaches circle as the limit of the number of sides tends towards infinity. My first (and second) time reading through the article I missed that (x) is not circle of x, but rather the [x]-gon of x.

You don't cease to exist, you cease to have ever existed (which might be better or worse than dying, but certainly sounds bad).

You applied this to evolution as if this was a grave concern of yours. Surely you don't believe that the universe will un-exist you for failing to have lots of children?!

The very idea of having never existed makes no sense! In a simulation, the masters could run back time and start again without you, but you still existed in the first run of the simulation. Once you've existed, that's it. You can believe that your future existen... (read more)

Well, I definitely am confused. What utility are you gaining or losing?

Is this an issue about your belief that you are created by Prometheus? Is this an issue about your belief in Omega or Prometheus' honesty? I'm very unclear what I can possibly stand to gain or lose by being in a universe where Prometheus is wrong versus one where he is right.

Count me wrong. You understood correctly the first time. See Vladimir's comment; the notation is confusing, but it is a finite process.

Hmm, now I think you might be right, and that I misunderstood the poster's original intention. The paragraph currently reads

... I'll spare the next [X] operators, and go right to (X) ("circle-X"). (X) follows the process that took us from triangle to square to pentagon, iterated an additional [X] times.

Is that an edit? I do not remember the phrase following the last comma. The notation is at least confusing, in that triangle->square->pentagon->...->circle ought to represent a limiting process, rather than a finite one.

Thank you. I would ask the op to use a less confusing notation, but I will go ahead and edit my other objections.

I think your final (larger) paragraph is confusing, but your conclusion is correct. That Omega presents you with a counterfactual only provides evidence that Omega is a jerk, not that you chose incorrectly.

Good question, but permit me to contrast the difference.

You are the hitchhiker; recognizing the peril of your situation, you wisely choose to permanently self-modify yourself to be an agent that will pay the money. Of course, you then pay the money afterward, because that's what kind of an agent you are.

You appear, out of nowhere, and seem to be a hitchhiker that was just brought into town. Omega informs you that you of the above situation. If Omega is telling the truth, you have no choice whether to pay or not, but if you decide not to pay, you cannot und... (read more)

Others in this thread have pointed this out, but I will try to articulate my point a little more clearly.

Decision theories that require us to two-box do so because we have incomplete information about the environment. We might be in a universe where Omega thinks that we'll one-box; if we think that Omega is nearly infallible, we increase this probability by choosing to one-box. Note that probability is about our own information, not about the universe. We're not modifying the universe, we're refining our estimates.

If the box is transparent, and we can see ... (read more)

Thanks. Unfortunately, now I'm horrendously confused. What's the point of choosing either? Unless Prometheus is apt to feel vengeful (or generous), it doesn't seem like there is any reason to prefer one course of action over another.

EDIT: I misunderstood the op, as can be seen from this post and the child.

I don't understand why no one else is objecting to treating (2) as a number.

If F(x, s) = {s-sided function of x}, e.g. F(2, 3) = /2\, F(2,5) = [2>, then clearly F(2,x) > 2^x for x > 3.

(2) is the limit of F(2, x) as x approaches infinity; just as 2^x is infinite in the limit, so is (2). I'm not even sure whether ((2)) is well-defined, because we haven't been told how it approaches the limits, and it's not clear to me that all methods yield the same function.

Either I don't get it, or you are misapplying a cached thought. Please explain to me where my reasoning is wrong (or perhaps where I misunderstand the problem):

When answering Newcomb's problem, we believe Omega is a reliable predictor of what we will do, and based on that prediction places money accordingly.

In this problem, Prometheus always believes (by construction!) that we will one-box, and so will always place money according to that belief. In that case, the allocation of money will be the same for people who one-box (most people, since Prometheus is... (read more)

It was not my impression that Prometheus might strike me down for disappointing him. If so, this would definitely change my behavior!

Also, if that was the point, this post applies very badly Azathoth, so I heartily agree with you there.

But you should only one-box if you think that the prediction of you one-boxing is tied to whether or not there is more money in the box.

In this case, as near as I can tell, Prometheus believes that you will one-box. Go ahead and two-box and collect the money. Unless we think Omega is lying, there's no reason to believe that one-boxing is superior in this problem.

Those are really big numbers, but while they start out large, the functions /x\, [x], ..., still grow more slowly than A(x,x), and are pitifully small compared to BB(x). I'm not actually sure where S(x) = {x-sided shape of x} fits in, except that it's computable, so still smaller than BB(x) (for all sufficiently large values of x).

EDIT: I misunderstood the definition of (x) as a circle, and thus as the end of a limiting process. The op intended it to be a polygon with [X] sides. The next paragraph is not valid, although the final one is.

However, (x) is not... (read more)

Police officers in larger cities make decent scratch to start with (IIRC 60k in some areas of California), and then have significant opportunities for overtime and "moonlighting" as security. In some cases there are Bay Area police making over 120k a year.
