References & Resources for LessWrong

[-]XFrequentist15y80

Nice idea, thanks for taking the time to compile these resources!

A few thoughts:

This would be easier to follow if the links in each section were ordered roughly from easiest to most challenging.
The length of this list is going to intimidate some new readers. One could productively add to the LW conversation after understanding a small fraction of these references. You should make it clear that these aren't prerequisite.
Some of the entries seem only tangentially related to LW (e.g. Haskell, Go).
The "Key Concepts" section might be better

* "Key Resources" are now called Relevant Websites. * "Key Concepts" are now at the very top. * I added "Note: Don't be intimidated by the length of this list. Most of these references aren't prerequisite. Only a small fraction is necessary to follow most of the posts and discussions on LessWrong. Before giving up rather just go ahead and read the Sequences, you'll see it's much easier to understand than this list makes it look like. And if you've trouble understanding some concept, just ask in the comments or come back and see if you can find some explanation via this companion." I know that some entries are only tangentially related to LW, but I wanted to compile a list that gives you as much as possible background knowledge to understand and participate on LW and integrate into the community. I believe that programming is a essential field of knowledge and that Go is not just very popular with people interested in LW related content but also one of the first hard AI problems people can learn about by simply playing a game. About ordering it from easiest to most challenging. Well, I can't do that. First of all it would likely mess up the categories and it is not clear to me what is easy and what not. This list is the culmination of feedback I received from asking, "What should I learn?" That is, although I'm reasonable sure that all of the items are of high quality as they were recommended by highly educated people who have read them, I haven't actually read most of it myself yet.

1XFrequentist15y

Thanks. This is much improved, by the way!

[-]Mass_Driver15y80

Very nice. My only suggestions are to (1) add a biology section, for people who haven't quite grok'd how the brain is an organ, and (2) tweak the physics section so that it doesn't lead off with quantum physics, if necessary by making two physics sections. The notion that the world's fiddly bits behave according to mathematical laws is neither obvious nor self-explanatory, and starting to explain this notion by reference to casually observable phenomena (rocks, light, magnets, water) rather than deeply confusing and occasionally controversial phenomena (quarks, neutrinos) is a really good idea.

3XiXiDu15y

I added a neuroscience section now. Pretty empty so far. The first link is Neuroscience for Kids which I was given by a professional neuroscientist as a valuable and easy to understand resource. The second link is a list made by me on controversial ideas regarding the reverse engineering of the brain. It also includes a video by EY and Anders Sandberg. I'll advance it with time and also add a category for biology in general.

3XiXiDu15y

Thanks, the physics section is now subdivided into 3 categories. I'll refine it according to your suggestion with time. I'll try to come up with a biology section too and ask a neuroscientist for some easy to understand resources on neuroscience.

[-]hamnox8y50

Want to note: I noticed the category "memetic hazard" and started immediately skimming the page to find everything labeled as such. Something is wrong with my reasoning here—

It wasn't the worst impulse to follow after all, since the category means something like controversial or fictional. Except... "memetic hazard" is a meaningful warning. I would prefer it keeps its value as a signal.

4AgentME7y

Guilty, I also immediately scrolled through the page for all of the M links. "Memetic hazard" sounds a bit enticing like "forbidden knowledge". Maybe EY was onto something with the ideas in the Bayesian Conspiracy that education should be dressed up a bit as "forbidden" but not actually restricted.

Marks with similar-looking letters (F and E) in light colors look bad on white background (hard to notice). Use contrasting darker colors (if at all) and more distinct text labels, maybe also bolded.

2XiXiDu15y

I changed the colors. I will think about some other form of labeling.

0DSimon15y

I suggest small graphical icons (~16x16) with distinctive colors and sillhouetes. Maybe: * A gray X over a black dollar sign for Free * A green exclamation mark for Easy * A yellow yield sign with an exclamation mark for Memetic Hazard (like your lightbulb one, but probably a lightbulb shape would be too small to make out at reasonable icon size). It would also be good to arrange the icons and entries in a table, so that a given icon always appears in the same column.

[-]Document15y20

All the M labels could use explanations, but in particular, why is A Fire Upon the Deep controversial?

3XiXiDu15y

It is a work of fiction that does contain bogus ideas that have been added to sidestep the problem of writing about a post-Singularity future (e.g. the Zones of Thought). Whereas a story like Three Worlds Collide does not deserve this labeling since it especially mentions its deliberate shortcomings and explains that they have been introduced to enable the writer to highlight and dissolve certain issues. If you think that this labeling policy should be altered, please elaborate on your reasons. That would be nice but might go beyond the scope of this list. Take for example CEV (Coherent Extrapolated Volition). It got labeled 'controversial' because there seem to be many people, even on Less Wrong, that take a critical look at it. The various objections may not necessarily be sound but the idea itself is popular enough to list it here. The label is there to indicate that the interested reader should search for a review of the idea if they are more than superficially interested.

Permutation City (the infamous science fiction novel by Greg Egan)

Why "infamous"?

3XiXiDu15y

Whoops! Yes, that's clearly the wrong word. Thank you. To my excuse, I never learnt English formally but basically taught it myself with time :-)

6gwern15y

I dunno, Permutation City is pretty infamous in my books because it presents disquieting ideas I don't know how to disprove. (Kind of like Boltzmann Brains or the Eternal Return.)

3rwallace15y

Thank you, I was about to comment on this; you've given me a needed data point. Permutation City is the only work of fiction I've enjoyed that I do not go around recommending, because I'm wary that to a reader without the requisite specialized background to separate the parts based on real science from the parts that are pure fiction, it might actually be something of a memetic hazard. If you are going to recommend it, I would suggest accompanying the recommendation with a link to the antidote

4gwern15y

So your strategy is basically 'subjective anticipation is a useful but ultimately incoherent idea; Permutation City takes it to an absurdum'? That's a good idea, but I don't think your antidote post is strong enough. Subjective anticipation is a deeply-held belief, after all.

2rwallace15y

I agree, I think the antidote post is better than nothing, but I recommend it in addition to, not instead of, the memetic hazard label.

1XiXiDu15y

I haven't added the antidote post as accompanying reading, as I have to read it yet, but 'The Logical Fallacy of Generalization from Fictional Evidence' post by EY. Reload and see the fiction section. Not sure, maybe a bit drastic. But at least it is obvious now.

2gwern15y

I don't think that Permutation City being fiction matters (if I understand your comment). The nonfiction ideas stand on their own, though they were presented in (somewhat didactic) fiction: that computation can be sliced up arbitrarily in space and time, that it be 'instantiated' on almost arbitrary arrangements of matter, and that this implies the computation of our consciousness can 'jump' from correct random arrangement of matter (like space dust) to correct random arrangement, lasting forever, and hooking in something like quantum suicide so that it's even likely... If it were simply pointing out that the fiction presupposes all sorts of arbitrary and unlikely hidden mechanisms like Skynet wanting to exterminate humanity, Permutation City would not be a problem. But it shows its work, and we LWers frequently accept the premises.

4XiXiDu15y

However, the book could also mislead people to believe those arbitrary and unlikely elements if they are linked to them on a list of resources for LessWrong. That's why I think a drastic warning is appropriate. Science fiction can give you a lot of ideas but can also seduce you to believe things that might be dangerous, like that there is no risk from AI.

2XiXiDu15y

I introduced a new label M for Memetic Hazard and added a warning sign including a accompanying text to the fiction section.

2rwallace15y

And I see a number of other things that merited the memetic hazard label also now have it, good idea. I'd suggest that it also be added to the current links in the artificial intelligence section, and to the link on quantum suicide. Maybe also add a link to Eliezer's Permutation City crossover story, now that we have the requisite memetic hazard label for such a link?

0XiXiDu15y

I thought quantum suicide is not controversial since MWI is obviously correct? And the AI section? Well, the list is supposed to reflect the opinions hold in the LW community, especially by EY and the SIAI. I'm trying my best to do so and by that standard, how controversial is AI going FOOM etc.? Eliezer's Permutation City crossover story? It is on the list for some time, if you are talking about the 'The Finale of the Ultimate Meta Mega Crossover' story.

4rwallace15y

I agree MWI is solid, I'm not suggesting that be flagged. But it does not in any way imply quantum suicide; the latter is somewhere between fringe and crackpot, and a proven memetic hazard with at least one recorded death to its credit. Well, AI go FOOM etc is again somewhere in the area between fringe and crackpot, as judged by people who actually know about the subject. If the list were specifically supposed to represent the opinions of the SIAI, then it would belong on the SIAI website, not on LW. So it is, cool.

4Richard_Kennaway15y

I hadn't heard of this -- can you give more details?

7rwallace15y

Everett's daughter, Elizabeth, suffered from manic depression and committed suicide in 1996 (saying in her suicide note that she was going to a parallel universe to be with her father)

5khafra15y

Not even the most optimistic interpretations of quantum immortality/quantum suicide think it can bring other people back from the dead. Does it count as a memetic hazard if only a very mistaken version of it is hazardous?

3XiXiDu15y

Why not? If you kill yourself in any branch that lacks the structure that is your father, then the only copies of you that will be alive are those that don't care or those that live in the unlikely universes where your father is alive (even if it means life extension breakthroughs or that he applied for cryonics.) ETA: I guess you don't need life extension. After all it is physical possible to grow 1000 years old, if unlikely. Have I misunderstood something here?

1DanielVarga15y

No, that's not what would happen. Rather, being faithful to your commitment, you would go on a practically infinite suicide spree (*) searching for your father. A long and melancholic story with a suprise happy ending. (*) I googled it and was sad to see that the phrase "suicide spree" is already taken for a different concept.

1XiXiDu15y

I'm not sure where you think we disagree? Personally if I was going to take MWI and quantum suicide absolutely seriously I'd still make the best out of every branch. All you do by quantum suicide is to cancel out the copies you deem having unworthy experiences. But why would I do that if I do not change anything about the positive branches.

0DanielVarga15y

My reply wasn't meant to be taken seriously, and I don't take the idea of quantum suicide seriously. But to answer your question, here is the disagreement, or really, me nitpicking for the sake of comedic effect: In your scenario, most of the copies will NOT be in universes with your father. Most of them will be in the process of committing suicide. This is because -- at least the way I interpreted your wording -- your scenario differs from the classic quantum lottery scenario in that here it is you who evaluates whether you are in the right universe or not.

1XiXiDu15y

Yes, we agree. So how serious do you take MWI? I'm not sure I understand how someone could take MWI seriously but not quantum suicide. I haven't read the sequence on it yet though.

5jimrandomh15y

Easy - if you believe in MWI, but your utility function assigns value to the amount of measure you exist in, then you don't believe in quantum suicide. This is the most rational position, IMO.

2DanielVarga15y

I am absolutely uninterested in the amount of measure I exist in, per se. (*) I am interested in the emotional pain a quantum suicide would inflict on measure 0.9999999 of my friends and relatives. (*) If God builds a perfect copy of the whole universe, this will not increase my utility the slightest.

4wedrifid15y

The is a potentially coherent value system but I note that it contains a distinct hint of arbitrariness. You could, technically, like life, dislike death, like happy relatives and care about everything in the branches in which you live but only care about everything except yourself in branches in which you die. But that seems likely to be just a patch job on the intuitions.

1DanielVarga15y

Are you sure about this? Isn't my preference simply a result of a value system that values the happiness of living beings in every branch? (Possibly weighted with how similar / emotionally close they are to me, but that's not really necessary.) If I kill myself in every branch except in those where I win the lottery, then there will be many branches with (N-1) sad relatives, and a few branches with 1 happy me and (N-1) neutral relatives. So I don't do that. Is there really anything arbitrary about this?

1wedrifid15y

The part that surprises me is that you do care about all the branches (relatives, etc) yet in those branches you don't care if you die. You'll note that I assumed you preferred death to life? In those worlds you seem to have a preference for happy vs sad relatives but have somehow (and here is where I would say 'arbitrarily') decided you don't care whether you live or die. Say, for example, that you have a moderate aversion to having one of your little toes broken. You set up a quantum lottery where in the 'lose' branches have your little toe broken instead of you being killed. Does that seem better or worse to you? I mean, there is suffering of someone near and dear to you so I assume that seems bad to you. Yet it seems to me that if you care about the branch at all then you would prefer 'sore toe' to 'death' when you lose!

1DanielVarga15y

You are right that my proposed value system does not incorporate survival instinct, and this makes it sound weird, as survival instinct is an important part of every actual human value system, including mine. Your broken toe example shows this nicely. So why did I get rid of survival instinct? Because you argued that what I wrote "contains a distinct hint of arbitrariness". I think it doesn't. I care for everyone's preferences, and a dead body has no preferences. And to decide against quantum suicide, that is all what is needed. In place of survival instinct we basically have the disincentive of grieving relatives. When we explicitly add survival instinct, the ingredient you rightfully miss, then yes, the result will indeed become somewhat messy. But the reason for this mess is the added ingredient in itself, not the other, clean part, nor the interrelation with the other part. I just don't think survival instinct can be turned into a coherent, formalized value. So the bug is not in my proposed idealized value system, the bug is in my actual messy human value system. This approach, by the way, affects my views on cryonics, too.

0wedrifid15y

This is a handy way to rationalise against quantum suicide. Until you consider Quantum suicide on a global level. People who have been vaporised along with their entire planet have no preferences... Would you bite that bullet and quantum planetary-suicide?

0DanielVarga15y

As I already wrote, the above is not my actual value system, but rather a streamlined version of it. My actual value system does incorporate survival instinct. You intend to show with quantum planetary suicide that the streamlined value system leads to nonsensical results. I don't really find the results nonsensical. In this sense, I would bite the bullet. Actually, I wouldn't, but for a reason not directly related to our current discussion. I don't have too much faith in the literal truth of the MWI. I am quite confused about quantum mechanics, but I have a gut feeling that single-world is not totally out of the question, and not-every-world is quite likely. This is because as a compatibilist, I am willing to bite some bullets about free will most others will not bite. I believe that the full space-time continuum is very finely tuned in every direction (*), so it is totally plausible to me that some of those many worlds are simply locked from us by fine-tuning. There are already some crankish attempts in this direction under the name superdeterminism. I don't think these are successful so far, but I surely would not bet my whole planet against the possibility. (*) This sentence might sound fuzzy or even pseudo-science. All I have is an analogy to make it more concrete: Our world is not a Gold Universe, but I am talking about the sort of fine-tuning found in a Gold Universe.

0wedrifid15y

Not nonsensical, no. It would be not liking the idea of planetary suicide that would be nonsensical, given your other expressed preferences. I can even see a perverse logic behind your way of carving which parts of the universal wavefunction you care about, based on the kind of understanding you express of QM. Just... if you are ever exposed to accessible quantum randomness then please stay away from anyone I care about. These values are, by my way of looking at things, exactly as insane as those parents who kill their children and spouse before offing themselves as well. I'm not saying you are evil or anything. It's not like you are really going to act on any of this so you fall under Mostly Harmless. But the step from mostly killing yourself to evaluating it as preferable for other people to be dead too takes things from none of my business to threat to human life. Strange as may seem we are talking about the real world here!

1DanielVarga15y

wedrifid, please don't use me as a straw-man. I already told you that my actual value system does contain survival instinct, and I already told you why I omitted it here anyway. Here it is, spelled out even more clearly: 1. You wanted a clean value system that decides against quantum suicide. (I use 'clean' as a synonym of nonarbritrary, low-complexity, aesthetically pleasing.) I proposed a clean value system that is already strong enough to decide against many forms of quantum suicide. You correctly point out that it is not immune against every form. 2. Incorporating any version of survival instinct makes the value system immune to quantum suicide by definition. I claimed that any value system incorporating survival instincts is necessarily not clean, at least if it has to consistently deal with issues of quantum lottery, mind uploads and such. I don't have a problem with that, and I choose survival over cleanness. And don't worry for my children and spouse. I will spell it out very explicitly, just in case: I don't value the wishes of dead people, because they don't have any. I value the wishes of living people, most importantly their wish to stay alive. You completely ignored the physics angle to concentrate on the ethics angle. I think the former is more interesting, and frankly, I am more interested in your clever insights there. I already mentioned that I don't have too much faith in MWI. Let me add some more detail to this. I believe that if you want to find out the real reason why quantum suicide is a bad idea, you will have to look at physics rather than values. My common sense tells me that if I put a (quantum or other) gun in my mouth right now, and pull the trigger many times, then the next thing I will feel is not that I am very lucky. Rather, I will not feel anything at all because I will be dead. I am quite sure about this instinct, and let us assume for a minute that it is indeed correct. This can mean two things. One possible conclusion is that

Surely actually performing quantum suicide would be very stupid.

I might try it once I have uploaded a copy to some general purpose quantum substrate. Just to see if it works :-)

1wedrifid15y

I get the impression that some people consider "take quantum suicide seriously" equivalent to "think doing it is a good idea". That makes not taking it seriously a good option.

0khafra15y

The way I understand quantum suicide, it's supposed to force your future survival into the relatively scarce branches where an event goes the way you want it by making it dependent on that event. Killing yourself after living in the branch where that event did not go the way you wanted at some time in the past is just ordinary suicide; although there's certainly room for a new category along the lines of "counterfactual quantum suicide," or something. edit: Although, to the extent that counterfactual quantum suicide would only occur to someone who'd heard of traditional, orthodox quantum suicide, the latter would be a memetic hazard.

1XiXiDu15y

What difference does it make if you kill yourself before event X, event X kills you or if you commit suicide after event X? In all cases the branches in which event X does not take place are selected for. That is, if agent Y always commits suicide if event X or is killed by event X then the only branches to include Y are those in which X does not happen.

1khafra15y

The difference, to me, is how you define the difference between quantum suicide and classical suicide. Everett's daughter killing herself in all universes where she outlived him only sounds like quantum suicide to me if her death was linked to his in a mechanical and immediate manner; otherwise, with her suffering in the non-preferred universe for a while, it just sounds like plain old suicide.

-1wedrifid15y

The difference between quantum and classical seems to be distinct from that between painless and painful.

I thought about doing that but feared that it would be edited mercilessly. Not that it would be a bad thing but I compiled this list for someone like me who needs a lot of background knowledge, elementary introductions and the assurance that there are resources that will help you out if you get stuck. Many people on Less Wrong are highly skilled and educated. When time I will create a Wiki entry to see what's going to come out of it. This list would have helped me a great deal when I started my self-education. It took a lot of time just to figure out what there is to learn, where to start and the necessary resources to learn from. With this list you can just go ahead and start learning.

I added Pearls of Functional Algorithm Design to the Haskell subcategory of the Programming section.

Richard Bird takes a radically new approach to algorithm design, namely, design by calculation. These 30 short chapters each deal with a particular programming problem drawn from sources as diverse as games and puzzles, intriguing combinatorial tasks, and more familiar areas such as data compression and string matching. Each pearl starts with the statement of the problem expressed using the functional programming language Haskell, a pow

I added the free book The Design of Approximation Algorithms to the Computer Science section.

It is a free book by David P. Williamson and David B. Shmoys, to be published in early 2011 by Cambridge University Press.

Interesting discrete optimization problems are everywhere, from traditional operations research planning problems, such as scheduling, facility location, and network design, to computer science problems in databases, to advertising issues in viral marketing. Yet most interesting discrete optimization problems are NP-hard.

Zed Shaw has come out with Learn Python the Hard Way, intended to teach Python to absolute beginners, which looks promising based on a quick browse.

He also wrote a blog post How To Write a Learn X the Hard Way, about the writing principles behind the book.

I added a foundations section to the physics category.
I added Ned Hall and L.A. Paul, on what contemporary philosophy thinks about causality and Being an Absolute Skeptic to the Epistemology section.
I added Less Wrong Rationality Quotes (Sorted by points. Created by DanielVarga.) to the Overview (LessWrong) section.
I added GitHub (Social Coding) to the general programming section.
I added The Art of Math to the misc math section.

"The Art of Math" clearly doesn't belong (as many other things; your list is too arbitrary).

I removed the link. I do not think that the list is too arbitrary but will refine it anyway. Many links originate from Less Wrong and other discussions about the subject matter, the comments having been upvoted or praised. Nevertheless I plan to ask people with good expertise in each category to review the links. So please bear with me. If you see something that is useless, let me know too.

Artificial Intelligence now has its own category including a sub-category for The Technological Singularity. The remaining Concepts have been moved to the Miscellaneous section as a sub-category.

AI grew too big and is too important as to be a mere subcategory of miscellaneous concepts.

I appreciate the labels, which are new since the last time I saw a draft. I recommend adding a summary break.

Perhaps a link to lukerog's the best textbooks on every subject.

Also, why no mention of the self-help aspects of LW?
