*linear algebra computational graph engine with automatic gradient calculation I really wonder how this will fit into the established deep learning software ecosystem - it has clear advantages over any single one of the large players (Theano, Torch, Caffee), but lacks the established community of any of them. As a researcher in the field, it's really frustrating that there is no standardisation and you essentially have to know a ton of software frameworks to effectively keep up with research, and I highly doubt Google entering the fray will change this. https://xkcd.com/927/

Add Julia to the mix as well (which I currently use and I find personally better than those other ones). I think TensorFlow's niche would be in the area of prototyping new ML algorithms as it seems pretty general, flexible, and fast. If you just want a simple deep neural net, it might be better to use Caffe or Theano. Those do not provide a flexible and general optimization framework, though. TensorFlow also seems more powerful in the area of language processing, as you'd expect.

I'm trying to figure out the business strategy behind open sourcing this. Android I got... open sourcing was a good play (maybe the only play) to compete with iPhone. Opensourcing TensorFlow could be a recruitment strategy - but somehow I think Google already gets top machine learning talent. Anyone have any ideas?

So reading Popper's otherwise good book on Bitcoin, Digital Gold (review), I was reminded of some of the crummy arguments for particular people being Satoshi, particularly some of the old Szabo chestnuts. I know a number of LWers also seem to overrate particular prospects. So in the spirit of 'betting is a tax on bullshit', I'd like to offer some bets. (Unfortunately, neither Augur nor Truthcoin are currently at the point where I could try out using them for this.) Before accepting my bets, I remind you that I have a pretty good track record in predictions... (read more)

Are you interested in betting it is one of the people on your list at 3:1 odds? My interest is academic, I have close to zero idea who may be Satoshi.

2gwern9y

You mean, would I be willing to take the negative on a bet that Satoshi is any of Szabo/Finney/Dai/McCaleb/.../O'Mahony at 3:1 odds? Hm... Yes, I would be willing to do that bet. (I know they sum up to more than that, but the odds aren't my true odds but upper bounds, otherwise I wouldn't make any money off offering the bets!)

Computer science is taught the wrong way at universities. Problem solving isn't the best way to learn how to solve problems; Programming isn't the best way to learn computer science. Computers are an instrument of computer science, but not the field, just as trumbones are an instrument of music, but not music. I reckon universities ought to offer computation courses, and programming courses.

3Viliam9y

The general rule of teaching is to progress from specific things to more general things. (As opposed to explaining the general things first, when the students are unable to imagine a specific example. Or when the students only know one specific example, so they are unable to understand what is the benefit of speaking abstractly.) I suspect the issue with programming is related. "Write a program that solves problem X" is too abstract for a beginner, who hasn't seen yet enough specific examples of "a program that solves a problem". The correct way is to start with giving examples: "program P1 solves the problem X1 (now let's look how exactly it accomplishes the task)", "program P2 solves the problem X2", "program P3 solves the problem X3", etc. Only after practicing this is the proper time to ask "what would be a program that solves a problem X".

0NancyLebovitz9y

Whether to start from the specific or the general probably depends on the student-- I have a general memory (sorry for lack of details) from someone who couldn't learn a programming thing until they had a explanation of what it was supposed to do. I'm not sure if this is the same thing, but I couldn't do word problems until realized that I was supposed to translate the words into equations and then crank it through mechanically. I thought I was supposed to read the problem and then perceive the answer directly. (It's quite possible they told me to do translation, but I wasn't paying attention.)

I think the article was making a stronger statement: programming isn't the best way to learn programming (at least at first). Sounds bonkers to me, but I don't trust my pedagogic intuitions.

I think most people are in it to learn programming though, if we redefine comp sci like this then it sort of changes what it means.

My Karma score vs. time and vs. my participation seems to be volatile. Is this unusual?

4OrphanWilde9y

Short answer: No, it isn't unusual. You have 23 comments total, if my lazy calculation is correct, all of which were made within the last three months, and around half of which were made in the past month. Your comments tend to be negatively voted, and some percentage of people here, when finding a comment they don't like, go through a user's history to downvote other comments they don't like. (The reverse is somewhat rarer, by my estimation, but also happens.) Since you're new and aren't well-calibrated on how a given comment will be taken, your comments will be all over the place. I note in particular a political angle to some of your comments, which - well, some of those who agree with you will upvote, most people here will downvote, as politics are discouraged. You have one comment with -20 Karma. I'm honestly impressed. I've never seen a Karma value that low before. One out of every three of your downvotes has come from that one comment.

2WhyAsk9y

Thanks for your answer. How do I find that -20 comment? Outliers can be ignored but at the risk of not learning something new.

5Vaniver9y

This is the page of your comments. I got to it by clicking on your username, then clicking comments at the top. Unfortunately, the comments can only be sorted chronologically with the most recent first unless you use something like WeiDai's tool, which can be sorted (but apparently only in descending order, and it doesn't seem to have the -20 comment). Since you have so few comments, it's relatively easy to look at them all and find it here.

1WhyAsk9y

Found it. The info in the -20 comment is, I believe, accepted as common knowledge by people who study "sexual politics." The different goals have to do with the nine months of discomfort females may have to endure while men have no such risk. Also see http://www.amazon.com/Chimpanzee-Politics-Power-among-Apes/dp/0801886562 I'd hope persons who feel that strongly would post their reasons for objecting but in this case I take what I read as fact.

3OrphanWilde9y

Your statement isn't interpreted as a dry statement of fact, but a signal about your beliefs about human sexual politics. Don't bring up, or hint at, those politics (or any politics, really) here, if you don't want to get downvoted. Nominally Less Wrong is anti-politics. In practice, there are political views that -can- get you upvotes, because people have a tendency to treat political beliefs they agree with as truths, rather than politics. I strongly recommend you stay away from anything even vaguely political until you see the patterns, however.

1Lumifer9y

I don't understand in which sense a statement along the lines of "it is the job of adult males to impregnate as many females as possible" can be seen as a fact.

1Viliam9y

Some obvious objections: * most adult males don't do this as a job; * technically, it should be maximizing the number of offsprings, not the number of partners; also, maximizing the number of offsprings that reach reproduction age, not just the number that is born, or even conceived; * if an adult male would literally try to "impregnate as many females as possible" (as opposed to merely professing trying to), he would have to become a serial rapist, a cult leader, a sperm donor -- probably all of that together -- but most adult males don't do that; * is–ought distinction, evolutionary-cognitive boundary, et cetera.

-1WhyAsk9y

To raise the likelihood that your genes will survive. Same reason for women finding a man with resources. It's probably somewhere in Game Theory. The oil sheik with harem arrangement may be an example of this. For me this is settled but if you can find counterexamples I'd like to read them. You could also try http://www.amazon.com/unSpun-Finding-Facts-World-Disinformation/dp/1400065666

5Lumifer9y

That's not my "job" and isn't really an imperative either -- lots of people remain childless by choice. I think it is an empirically observable fact that males do NOT attempt to impregnate as many females as possible and the women do NOT stick to the richest male they can attach themselves to. It's just not happening. Maybe you think this is the way it should be or was meant to be, but your opinion is normative, not descriptive.

-1WhyAsk9y

I give up.

5gjm9y

You would do better to engage and consider seriously the possibility that you might be missing something. It looks to me as if either (1) you are taking pop evo-psych as literal unquestionable fact, in which case you're making a mistake, or (2) you are deliberately being inexact and handwavy while others take you literally, in which case they're making a mistake but you can correct it and move on. If #1, then I think Lumifer's objections really should be sufficient to make you reconsider. It demonstrably isn't the case that men devote their lives to maximizing offspring, still less to maximizing the number of different women they impregnate; similarly for women and maximizing the quality of their offspring. So any set of ideas that leads you to say they do must be wrong. If #2 -- e.g., if what you really mean is something like "there are evolutionary pressures pushing us toward maximizing offspring number for men and offspring quality for women, and maximizing these things is very different from thinking rationally and may sometimes be impaired by it, so we shouldn't expect our brains to be well optimized for rational thinking" then I think you will find that (as well as getting a better reception here) you will think about this stuff more clearly if you're more explicit and careful about what you're claiming. E.g., it seems like rational thinking could be a useful tool for maximizing offspring number/quality so it's not at all clear that being optimized for offspring has to be an obstacle to thinking rationally; there's some pressure for men to optimize quality and women to optimize number too, which maybe makes some difference; there are such things as kin selection and (in special circumstances, whose rareness is disputed) group selection, and these can help genes to prosper even if their direct effect on offspring is negative; etc., etc., etc.; it's easier to assess the impact of considerations like these on your argument if your argument is more precise and

0Viliam9y

A shorter version of how I understood it: * There are people who love creating X. * There are people who admire X. Not being creators, their love of X manifests by supporting the creators: socially or otherwise. * Sometimes a cool community appears as a result. * There are many people who want the "cool" part, but don't intrinsically care about X. They join the group, but they complain that the X is too X. (What they really want is something 99% mainstream, with a small flavor of X, pretending to be the original X-centered community.) * Unless actively fought against, these people soon become a majority in the community, because the population contains much more people who want to be cool than people who love X. This creates a tension between the old fans and the new fans. * Finally someone sees the real dynamics of the group, and provides the masses exactly what they want (something 99% mainstream, with a small flavor of X, pretending to be X), in exchange for fame and money. Now there is a tension between the old creators + fans and the new creators + fans. * The old creators + fans complain that the community does not care about X anymore, but they are a minority, so they gradually retire from the community. (If they try an open conflict, they lose.) * In the absence of people who care about X, the community loses what made it unique. It is not cool anymore. Everyone is disappointed... except for the new creators, who easily move to another community ready to be exploited. What can be done to prevent this? * Create costly barriers to entry; don't let the "fake fans" in. -- Problem: You give up the resources that even the "fake fans" would bring. Also, by being less famous, even the people who care about X may not find you. * Keep a limit on the number of "fake fans". (Author suggests that 6:1 ratio of "fake fans" to "true fans" is optimal; 10:1 is too much to handle.) -- Problem: The old members would have to consciously understand the strate

1Lumifer9y

Why do you think this should be prevented? "Accept this life-cycle as a reality" seems like a reasonable approach. The "old members" can keep their identity if it's really tied to hardcore-X. Or they can sit on their porches and grumble about kids these days :-)

1Viliam9y

It's a waste of resources. For example, if the LessWrong website becomes boring and people move somewhere else, they will again have to design the web page, implement technical features, etc. Even more resources lost if the same thing would happen with MIRI or CFAR. Not only the money and work would be lost, but also prestige and contacts; some useful people would probably be left behind... There are more options than just "go away a start again" or "grumble". But these two are the easiest options, which is why people have to choose between them if they are not strategic.

0Lumifer9y

Only from the central-planning point of view. In a fluid and dynamic system the fact that something was useful a couple of years ago does not mean that it's still useful now. Your "waste of resources" is re-confirmation that X is still useful and can draw people, otherwise it's deadwood and should be discarded to die in a fire.

This isn't bad, though I feel like: would apply to the XKCD example, but not to the people claiming that the Lebanon attacks should've been publicized more than the Paris attacks. I hope I'm not treading too much into political territory here.

2Viliam9y

That would be closer to Nirvana fallacy, applied to activism. "People do something good. You criticize them for not doing something better instead." This argument happens all the time. See also The Copenhagen Interpretation of Ethics. There is a standard solution S0 that almost everyone chooses. Someone chooses a better solution S1. They get attacked for not choosing even better solution S2. The harmful part is that choosing S1 over S2 is socially punished, while choosing S0 over both S1 and S2 flies under the radar. If the reason for choosing S1 over S2 was that the solution S2 was too complicated or too expensive, we effectively teach people to choose S0 over S1 to avoid the punishment in the future. (Specifically: S2 = reporting on Lebanon and Paris attacks appropriately; S1 = focusing on Paris; S0 = ignoring both.)

Correction: first is an example of weak man argument mixed with personal uncomfortability. However, we could also strong man that as character 1 being agnostic and annoyed at people's attempts at arguing for certainty on the topic. Second comment is a variant on "my opponent believes something" (noncentral fallacy territory) but breaks into genetic fallacy with the emotion part. My opponent feels annoyed by two opposing groups which is kind of like he thinks that they are intrinsically inferior which is kind of like he thinks he is better/smarter than them which is kind of like he had a superiority complex which is kind of like he doesn't care about the issue at all which is kind of like he is just self centered which is kind of like he's a bad person.

I'm out in a small town pretty much every week, and I'm always happy to go back to the city. Mostly it's the people. Everybody smart enough to do a knowledge worker job has left. Everybody creative enough to make art has left. Everybody who understands the value of excellent education for their kids has left. Everybody young and beautiful enough to get into the dating scene has left. Everybody who wants an exciting life has left. The people who remain are still nice (everybody everywhere is nice, really) and often admirably hard-working, but they're slow and seem to live inside fairly tight horizons. I like to be among people I can learn from, and I find those in the city. I also like life in the city because I like to travel, mine has an airport and excellent public transport, and I really like not owning a car. To live an hour away from the nearest big city would mean that everything in the world would be an hour further away. So I might reconsider when I can call up a self-driving electric taxi to take me places at any time, or when VR takes off in earnest and I spend much of my time in there. But by that time, I imagine life in the city will have become even more interesting, and life in the country will have fallen even further behind.

Mostly only answering the short question, but: most of my friends are from reddit. This is super convenient, and I'd be very hesitant to move somewhere that didn't have a similar ready-made community for me. (But I don't know how I'd tell. I imagine only a handful of cities worldwide have a suitable subreddit, and a handful have large rationalist communities. Beyond that, I'd want to check for sunday assembly and for Meetup groups. But I guess not every community of suitable size and demographic will be a good fit for me, and I don't know how I'd test that in advance.) London also makes it easy to take up hobbies, and I imagine that would be more consistent in big cities. Your current location might not lack anything you currently want, but that may be partly because you haven't had a chance to discover you want them.

9SGrouchy9y

I'm in NYC, and hobbies here are INSANELY expensive. Sure, there multiple makerspaces, but their memberships are all $400/mo+. Classes are expensive. Rent is so high that no one has room for hobby equipment. I would like to try brewing, but have nowhere to put a big jug. There are a lot of hobbies I would like to try but I have to space for it. Also, there's not a lot of free and open space for hobbyist groups. Contrarily, I've also lived in the Midwest and the Pacific Northwest in mid-sized cities, and THERE was the sweet spot for hobbies. Big enough that there are people interested in esoteric things, but small enough that it was affordable and there was space for it. Also, I actually prefer the more tight-knit groups that result from esoteric hobbies in midsized cities. In NYC, there are hundreds of people interested in Underwater Basketweaving, but in Generic Midwest City there are only 10, and so those 10 people become a close-knit community. Furthermore, in NYC it takes an hour to get ANYWHERE. For one of my main "LOCAL" hobby groups, all the get-togethers are anywhere from 1:30-2:00 away. Almost everyone I've dated here lives about an hour away (the exception is if they happen to live off the same subway line). But in Generic Midwest Town, you're never more than half an hour away from local groups. Travelling two hours would put you in a completely different city/scene.

2Dagon9y

I suspect there are regional differences that matter as much or more as size does. A 200K city in Europe that's a short train ride from a larger city is going to feel very different from one in the southern USA with no easy connection to a metropolis or one in the west that's kind of sprawling connection of similarly-sized cities, which adds up to a large city, but over many square miles. Job is definitely one of the most common motivators, but a lot of people are drawn to aspects of the "character" of a location, which is more some mix of common habits, popular amenities, and other social expectations which make your life and interaction styles seem more or less weird than other places.

Do you agree with this statement: 'my work/school is the most important part of my life' (it's a item used to measure conformity with masculinity, haha) and why?

I suspect it's a shitty, very ambiguous question but that's the way psychological questioners often are.

I'm trying to ascertain ways that double barreled questions might be interpreted. I don't really care about your specific answer, just how you come to either a ''agree'' or ''don't agree'' if your answers are going to be coded as one or the other.

0gjm9y

I bet most people answering this question do so not by any sort of reasoned consideration of how important work, family, sleep, video games, music-making, sport, etc., etc., etc., are to them, but by a quick System-1-ish consideration of how the question makes them feel. And I bet anyone using this question to measure "conformity with masculinity" or any other psychological characteristic are relying on that. This sort of thing is omnipresent in psychological questionnaires, which I guess is what you're getting at in your second paragraph. So, anyway, the sort of things I would think about if I were trying to answer this question while taking it more seriously than I think its authors did: * What would hurt most to lose? (This is Tem42's approach.) By this criterion, work comes out quite important but other things -- e.g., my family -- clearly ahead. * But that may be misleading; e.g., one reason why losing my job would hurt less than losing my daughter is that I can probably get another job much more easily and quickly than another daughter. But that doesn't seem like it's the same thing as importance. * What gives me most satisfaction? By this criterion, work does OK -- I like my job pretty well -- but many other things do better. * That may also be misleading. If I really disliked my job but had no savings and a family to feed, work might be very high up on the list of important things while still coming below Nothing At All in satisfaction conferred. * What do I spend most time thinking about? * Could well be work. But does this mean that if my employer suddenly demanded double the working hours (and for some reason I couldn't refuse or quit or anything) it would become much more important to me? I'm not sure that's right. * What do I voluntarily put most effort into? * Could well be work. But it seems like we should be distinguishing intrinsic and extrinsic motivation -- a major reason for putting effort into work is simply that I get paid for

I would enjoy having more opportunities to practice spoken English. But I would have to trust the other person to speak correctly, so they are not teaching me their mistakes. Non-English native speakers talking to each other has a risk to propagate "false friends". I am much better at writing English than at speaking. It helps that I can "cheat" by using Google Translate in the few difficult cases. But also because I have much more practice writing, and in conversation I sometimes realize I am actually not sure how the word is pronounced... or I just pronounce it my way, and the see the confused look on the other person's face.

I live in Germany and I do from time to time use English to speak with friends who are natively German. But nobody of them cares about German national identity. As far as I understand many people who do care about their national identity wouldn't just switch to English because it goes against their political beliefs. Two average Frenchman would feel like traitors for switching to English with each other. Have you thought about using text-to-speech software to create texts on the computer? I would guess that trains proper pronunciation because otherwise the computer won't understand you.

Hypothetically, say I'm an independent politician, or a politician from a minor party, in a Governments senate. The ruling party or their opposition has promised me a diplomatic appointment after my term in parliament ends in return for my support in certain things. Given that politicians frequently lie, and if I leave parliament I will have minimal media clout thereafter, can I somehow use a smart contract or some kind of political manoeuvre to ensure compliance without revealing the nature of the agreement prematurely, which may damage the clout of my associates and political allies?

4ChristianKl9y

I don't think you have a good model of politics. Politics is about people. A promise like this isn't made by "the ruling party" but by individual politicians of that party.

0PipFoweraker9y

One area to explore would be the concept of smart contracts, currently best exampled by experiments with blockchain technology - Ethereum and transparency in prediction markets would have places to start. One possible solution to a real-world non-criminal application of that problem would be to hire a neutral third party with appropriate confidentiality trust - like a lawyer - to create an agreement, witness it, and hold it in trust. This becomes less reliable when you start delving into the ethical problems outlined by other responders if you're trying to create something deniable, but you can probably work around that with an 'if-then' agreement with a lawyer and a pre-sealed envelope.

What are the specific reasons you are considering this procedure-- for libido reduction, or for the health benefits, or for the ostensible life expectancy increase this procedure might provide? You don't have to answer these questions here, but I'm posting them to make sure that you yourself know your own specific reasons for wanting to be castrated; if you know them, you can focus your research on those areas. Regarding bone density, I'm not sure how much chemical castration hurts you. In any case, I seem to vaguely recall that there's other stuff you can do to maintain bone density as you age (some of which women tend to pay more attention to then men), so do look into that if you decide to follow through with castration. It's been a while since I looked into this, and I looked into the stuff on physical, rather than chemical castration, anyways (I don't have a good intuition on how much the two differ on most axes, since I didn't ever look into the chemical castration side of things much). What I'm trying to say is that it may be wise to set aside the research you find on physical castration if you are committed to going the chemical route, unless you're able to convince yourself that it's relevant. Now that I've disclaimed that which I needed to disclaim, in the spirit of blatant self-promotion, there's always this post.

It would be the most helpful if done prior to puberty. I'd worry about cardiovascular side-effects, fat accumulation/redistribution, mental side-effects (something something spatial rotation)... basically, I've studied this on and off since puberty (and not before, because life would be boring if I could do anything right the first time), and concluded that, given my current state of health, castration would probably make more things worse than it improves. Actually, I concluded that circa 2008, and I'm pretty sure I was ever-so-slightly healthier then.

2[anonymous]9y

Interesting, might have to look into this some more. Yeah, the fat distribution thing motivated me not to transition MTF when I was in high school. That and plenty of trannies regret it, most don't pass, and transitioning is more fad than evidence based treatment to gender dysphoria. Plus I reckon in retrospect it was just a bit of transvestic fetishism which isn't good to 'treat' with transitioning. But yeah, different reasons now.

6Kaj_Sotala9y

Really? I'd heard the opposite, that regret is rare and that transitioning clearly improves quality of life. Based on a brief Googling, most studies seem to find low regret and improved quality of life post-transitioning, according to e.g. http://transascity.org/quality-of-life-in-treated-transsexuals/

0[anonymous]9y

IIRC, transitioning improves QOL for people who don't fall into a number of exclusions that I'd suspect are very frequently comorbid with self-reports of transgender identity and/or gender dysphoria. On the same token, I reckon lots of people without gender dysphoria can benefit from transitioning, depending on their risk tolerance, undersanding of sexual strategy and such. But that's not gonna be a useful spiel for many if anyone who will read this. ... Yes, I would hear the opposite too predominately, before I started looking into it with a neutral frame. I'm not saying the evidence would stack that way again now, since I did my informal survey of the evidence for myself years ago. But, some reasons to be skeptical of the answer of 'transition' to the instances of gender dysphoria: Bias On the internet, there are some of the most blatant reporting biases. Particularly when there are communities to generate a particular kind of sentiment. Combined with significant political influence and 'alliance' with the other LGBI bla bla bla letters, you get yourself, well, a huge circle jerk. If you're looking for something with the slightest bias in your keywords, you're likely to find it. Heck, Google's AI could pick up on bias in your keywords 6 months ago in the search results it shows you. The systematic review linked to is very good, actually. But it's hosted by a trans collective. I'd be suspicious of bias naturally. That may just be an artifact of pay-walling that they're kindly willing to flour though. methodology Their primary outcome of interset is suicide risk yet it looks like there are only 3 studies that report on it - 1 saying transtiioning increasing risk the others saying it decreases, then about 20 studies not reporting on it...doesn't give me any confidence in the paper. My general impression from interaction with an (albeit, marginalised subpocket) of transexuals is that the sophistication of current psychological tools are insufficient to grasp t

2Richard_Kennaway9y

I'm not sure that any ever do. It is, I have heard, standard wisdom amongst experienced transsexuals, that every time you walk down the street, you will be read (as they call it). Not by everyone all the time, but every time by someone. The most that can be achieved, which is largely up to the people around one rather than oneself, is to be accepted as a transsexual, as someone who has chosen to adopt certain gender appearances and performances. Becoming indistinguishable from the other sex, even if only in non-intimate situations, is not currently possible.

2WhyAsk9y

". . .my sexual urges. . ." You're scaring me. I'm not a doctor, but DSM II through V may give you a prognosis, and society's views on your problem as those views evolved over these several editions.

As far as I can tell, there have been no study about the bone density issue in male castration, so good luck on finding one. However, the problem has been study in relation to DMPA used as a contraceptive, and in that case the effects are shown to be real, although reversible. It is possible that the effect on male are not wildly different. That strikes me as peculiarly contradictory: why would you care about attractiveness once sexual urges are gone?

8Viliam9y

It may impact other areas in your life. Even if you are not interested in other people sexually anymore, other people may feel attracted to you, and this may uncosciously influence their decisions to e.g. hire you at their company. (One of those things that shouldn't happen in the ideal world, but happen all the time in our world.) People attracted to you will more likely become your fans, if you want to be an artist. They may even be more likely to interview you if you are as scientist. Shortly, other people's opinions matter, and other people's opinions of you are often based on how attractive they consider you (see: halo effect).

The usual bias of highly intelligent people: "You have to do everything alone!" Why it exists -- Well, if most of the time you are surrounded by people who compared to you are idiots, cooperating with them or delegating tasks to them seems like a really bad idea. And the obvious alternative is to do it alone. How it fails -- Once internalized, it is difficult to get rid of the habit even when you meet other highly intelligent people. Also, if you do the math correctly, many tasks are worth delegating to less intelligent people, because the average value of the outcome is still positive. How it shapes people -- If you alieve that cooperation is impossible, your remaining options are either fatalism or hero worship (and depression, when you realize you are not the superman, and will never be), depending on whether you believe that individuals able to fix large problems single-handedly exist or don't. Why did I post this as a reply to your comment: So far (cutting away the rest of the sentence), there is nothing wrong with this; it describes a productive person. Here comes the hero worship.

Global Warming is high on my list. The cost for reducing CO2 in the atmosphere seems low enough that this may be the best way to solve it. There are proposals to remove CO2 from the atmosphere at ~$100/tonne. Intuitively, it seems the cheapest way to "remove" CO2 from the atmosphere is to not put more there in the first place: to stop digging up C and burning it. We could still have liquid and gaseous hydrocarbon fuel, we would just need to derive it form biomass: algae and jatropha are both probably in the less than $100 per barrel range, with, I think, algae being very scalable. I wonder if buying up all the coal and oil in the ground and keeping them there once owned wouldn't be the cheapest way to keep C from underground from making it into the air. Human Population Growth. With less population, all other resource constraints become easier to shift towards sustainable solutions. I'd like to see fertility control tied to aid: you want welfare or international aid, you get fixed. It strikes me the absolute best place to lower population growth is among populations that can't support themselves.

Given that the public ledger can be scrutinized to identify insider trading by financial institutions prior to commitment, and the high-cost to entry into the bitcoin market what incentive do orthodox financial institutions have to buy-into and legitimize the bitcoin market instead of adopting the technology afresh in cahoots with one another?

1ChristianKl9y

If I understand part of Ripple's plan is to provide banks with the ability to easily settle debts internationally. I don't see a reason why a bank would use Bitcoin. bitmesh might be a way for bitcoin to get larger adoption. It seems to me like having a micropayment transaction every 5 seconds as their current video suggests isn't doable at bitcoins transaction fees. Doing it in Ethereum where it's possible to put money into escrow might make more sense. Ethereum also has decent business models with Augur and Proveance that have the possibility to provide value that people can't get easily outside of crypto-currencies.

0mwengler9y

Orthodox institutions will potentially have the same reasons to adopt bitcoin as they have for adopting USdollars, swiss francs, and the euro: there are customers willing to pay for their bitcoin services. Bitcoin will be adopted by customers (ignoring speculators and fanboys) because there are things they want to do that they can do more easily, more quickly, or less expensively with bitcoin than through other means. Will Bitcoin be adopted by customers at sufficient rate to be adopted by financial institutions, or more generally, to succeed? I certainly don't know. I do know that I have no reason to adopt bitcoin. My credit cards cost me nothing, even though they may cost the businesses I use them at a few percent. I am not involved in transferring money internationally. Credit cards and international transfer of money are two areas where I have read claims bitcoin provides less expensive service. I am not convinced, however. Can bitcoin replace credit cards? I don't think so. Credit cards allow for an instant transaction with a fee of a few percent charged for the instantness. That fee is presumably largely there to pay for fradulent transactions. Does bitcoin do this? No. Bitcoin may provide fraud free transactions through the blockchain, but only if you wait, with guidelines suggesting a day, and "common sense" suggesting maybe three blocks in the blockchain showing the transaction in question. So thirty minutes? Certainly if Amazon offered me a 3% discount on my purchases if I used bitcoin, and they wouldn't ship until 1 hour had gone by, I would take it. But would I want to pay for a meal in a restaurant and be physically restrained from leaving for 30 minutes while we waited for blocks including my transaction to come in? Credit cards used in the real world for small transactions are not going to be threatened by bitcoin in my opinion. I can't speak to international transfers due to lack of knowledge.

0Lumifer9y

Irreversible does not mean "fraud free". In fact, one the useful aspects of credit card transactions is that they can be reversed if need be. International transfer of money is basically about avoiding national capital controls. Bitcoin got quite a boost out of the Chinese trying to get their money out of the country.

0ChristianKl9y

For most purposes a single block is enough. I think there only one case in bitcoin history where it wasn't and the victim was a gambling service that was considered to be hostile to the bitcoin network for spamming it. In many places restaurant these days accepts checks. There no real reason for a restaurant not to trust a person to not double spent.

Trusting a check implies that you can trace it to a bank account, which, thanks to the Know Your Customer regulations, in most cases can be linked to a specific person. Trusting a bitcoin payment implies that you trust a disposable number.

Pretty sure the sugar is necessary for preserving. You could make it without sugar, but it would just be pulpy juice-water (the sugar is also a thickening agent), and you would have to eat/drink it pretty fast because it will go bad quickly (I would guess a couple days)

[-]TezlaKoil9y100

In a sterilized and sealed jar, jam made without sugar can last for years. Once you actually open the jar, you have about 7 days to eat it, and you better keep it refrigerated. You don't need the sugar for thickening - the pectin in the fruit thickens jam just fine.

However, if you don't add any sweetener, the result will be very sour.

When I was a little kid we used to make blackberry jam. You can just pick wild blackberries in some places, which is quite a lot of work, but hey, you're out in nature, it's fun, and it's free. Looking back I think it was mostly my parents picking berries while my sisters and I were running around and playing in the forest and eating half the berries our parents picked. The recipe for making jam is indeed just berries, water and sugar. We used a large pot though, not a frying pan. Just cook and steer until it's done. Pour the jam into a jar while it's still hot, and screw the lit on. As the jam cools it'll create a slight underpressure in the jar, helping preserve the jam and tightening the lit even further. Sealed properly it can stay good for a long time. One year we kind of overdid things (my sisters and I were a bit older, and actually starting helping instead of 'helping') and ended up with over 300 jars of blackberry jam. They were still good 10 years later. Self-made jam tastes much better than store-bought jam. Whether that is because it actually tastes better, or because your brain just thinks it tastes better because you made it yourself, I don't know. But it doesn't matter, the end result is the same.

In general, should we usually assume no effect modification for the continuous of character outside groups that share some features of an exemplar, or assume effect modification, assuming coding all novel exposures as binary traits (e.g. if I know trees are dangerous, and I see a grass (perceiving a small tree), should I assume it's dangerous? or do I assume that because it's small that will modify effect and outcome will be non dangerous?)...is there name for this?

It's not a quote from something. It's very abstract and includes technical language that doesn't capture very well the concepts I'm trying to articulate. The absence of terminology to describe what I want makes it hard to understand. This isn't aimed at everyone.

3gjm9y

I think it has other problems besides abstraction and technical language. Example 1: "for the continuous of character" doesn't appear to be grammatically correct and it's not clear what you actually mean by it (is one of the words an autocorrect error for something else?). Example 2: when you ask "is there [a] name for this?" it's not clear what "this" actually refers to. (Also: the key virtue of technical language is its ability to capture certain concepts precisely. In cases where it fails to do this, you should at least seriously consider abandoning technical language.) It seems like the point of your answer to Bryan-san is to say that your intended audience won't need to expend time and effort decoding what you wrote. I think you are wrong unless the intended audience is empty. Since you apparently don't value your readers' time enough to make your meaning clearer, I'll have a go. I may well fail, for exactly the same reason as it seems like a paraphrase might be useful. If something like that is the question you're trying to answer, I think it's obvious that the answer is: The question is much too vague to be answerable, in the same way as "Suppose I'm thinking of a number. Is it an odd number?". Some differences affect (or should affect, or could reasonably be expected to affect) some attitudes. Some don't. Without more information there's nothing more to say. (Note: I do not myself generally consider trees dangerous or men sexy. Hypothetical examples are hypothetical.)

09eB19y

I think your paraphrase makes sense if Clarity was accidentally using the term effect instead of affect (in it's "feeling or emotion" definition). But that doesn't really fit with the last use of effect, so I would translate Clarity's use of effect as "property" or "trait". My paraphrase would be: I would say that if this is the intended meaning, you should assume that it shares other properties, even though it differs, strictly speaking. Mostly this is because we are coding all properties in strictly binary terms rather than as probabilities. If you had extensively studied dangerous trees, then someone showed you grass, and then they asked you binary questions about its properties, you'll be correct in assuming the answer to the questions was identical for the tree and the grass. You'd get some of them wrong, but the vast majority you'd get right. Trees and grass are much more closely related than grass and petroleum, or grass and love, or grass and President Obama. We do this in the real world. Most cleaning supplies are toxic, but none of them are carbonated. If someone handed you a bottle of some novel cleaning supply, and you saw it was carbonated and milky white, you'd be right to assume it was toxic even though it clearly has some properties different from all the other cleaning supplies you've seen. Of course it would be better to have a probability distribution about whether it's toxic.

The version that sort of works are "existence futures" (that's not the standard name, unless I happened to reinvent it). Eli pays someone $1 now, and that person pays Eli $N dollars in M years. N is a combination of the interest rate and the person's belief that they and Eli will still exist in M years. If I think there's a 50% chance that the world will end at the start of 2016, and Eli thinks the chance is 0%, both of us would see a deal where he gives me a dollar now and I give him $1.50 on Feb 1st as profitable. The trouble with them is that if I really think the world is likely to end on Jan 1st, I'm probably making a host of similar decisions that make it unlikely that I'll actually be able to repay him on Feb--if I'm selling everything and playing video games until the world ends, then when the world doesn't end, where is the money going to come from to repay Eli?

The usual answer is escrow.

Right, but the only way this makes sense for Eli is if he's paying me less money now than I'll pay him in the future, and the only way it makes sense for me is if I get to spend the money before the world ends. If I have to put $1.50 into escrow in order to get access to $1, then I'm losing money, not getting it. You might be able to get it to work with durable assets--if I want to use my car and house up until the world ending, then I can ask Eli to pay me for them now in order to get them after I think the world will end. But it's not clear this works out any better for the endtimer than taking out a standard 30-year loan that they don't expect to have to repay.

I see. Yes, you point out a valid problem.

Why? I don't think UFAI can kill us in mere hours/minutes, and at some point during the months or years it will probably take, someone, somewhere, will notice what's going on. They probably wouldn't be able to stop it, but there's every chance it would become known. And for my apparently abundant downvoters, the whole reason I'm asking to take bets is because some people repeatedly profess to believe precisely that every fresh machine-learning advancement is a dangerous step closer to a very sudden self-improving UFAI that destroys us all. So I'd like to find out their degrees of certainty regarding exactly how far machine learning can go before it crosses a classification boundary and becomes UFAI. Anyway, I've got the first of several ANNABELL training sets being processed on a spare machine in the office.

By the standard of "someone somewhere noticing" we have proof that aliens are on earth. Nobody will take that as a way of resolving a bet. A powerful UFAI can control cyberspace before it kills everyone. You would need cyberspace to function to resolve a bet. It took a while after WWII till Italy's public recognized that the Mafia was back. An UFAI would make a mistake at waging infowar for it's identity to become public knowledge. If you believe that UFAI's would go FOOM then they are unlikely to make mistakes. You get the downvotes because the average person who holds that belief has no reason to take the other side of the bet. Getting money on doomsday is not a valuable outcome.
