Erm, no we don't. Perfect and imperfect information refer to the knowledge (or lack thereof) of the state of the game, not the state of the other player's mind. Iterated prisoner's dilemma is a game of perfect information, as every player has full knowledge of all previous moves and what moves are available for the opponent to make (as opposed to, say, Battleship, where you don't know where your opponent has placed his pieces).

What you're talking about is superrationality, which is where a player assumes that, since he and his opponent are both completely rational and have access to the same information and have the same decisions to make, they will both make the same move. The reason the prisoner's dilemma is a dilemma is that a "rational" player will not make the best decision, since no matter what the opponent does, it is always better to defect; this leads to the conclusion that both players will always defect, which is the worst possible outcome. That's the traditional theory, anyway. A superrational player, on the other hand, will rule out outcomes in which the opponent makes a different move, so the only possibilities to consider are the cases where both players defect or both players cooperate. Here, cooperation is the best move, and the dilemma is resolved. Yay.

Uh, yeah. Hence why you need a directional antenna. All is not lost, however, as you can crudely convert an omnidirectional antenna into a directional one using ordinary cooking utensils. That should give you a range of at least a couple of hundred metres (within line of sight).

Can you clarify this? By "killer", do you mean one who killed in the previous round, or one who has ever killed? That is, would you kill a Grudger (one who always kills against an opponent who has previously killed, even after the opponent stops killing)?

Dinosaurs (at the kinds you're talking about) had proportionally thicker legs than chickens. They're a different beast entirely. The question was specifically about horse-sized chickens, not horse-sized dinosaurs. A chicken cannot be made horse-sized without either killing it nearly instantly or giving it (proportionally) thicker bones and muscles, a smaller body, a larger heart and lungs, and so many other modifications that it no longer even remotely resembles a chicken.

Definitely the horse-sized chicken. The Square/Cube Law says it would break its scrawny legs the instant it tried to stand up before quickly dying from its weak heart failing to pump its massive volume of blood to its oversized body. I win by default.

There's a huge difference. In war, you're not allowed to attack non-combatants.

True, but since this is just a game, the non-aggression principle only requires that everybody play by the rules, nothing more. If anyone wishes to model their strategies after the NAP, they're obviously welcome to do so, but it would be dangerous for an opponent to assume that anyone who follows the NAP in real life would/should apply it to a game.

Go right ahead. Though you'll probably get the same amount of sympathy as the Darwin Award contender who tried to escape police by firing at them with a gun loaded with blanks (to fuck with their minds, no doubt), which ended about as well as you would expect.

On the other hand, cooperating with everyone indiscriminately works without having to find specific people to cooperate with. But why don't you put your theory to the test instead of just talking about it?

Actually, what I described was a war, not a democracy. I don't have much hope for you if you can't tell the difference.

No, they're not. You threatened them. That makes you the aggressor. Besides, it's a game, in which all players agreed to the rules. The non-aggression principle doesn't mean you can't throw the first punch in a boxing match, as boxers consent to getting punched as part of the sport (provided said punches conform to the rules of boxing, of course). It's the same here. You want to play this game, you have to accept the risk that someone will "kill" you first, because the rules of the game allow it.

Obviously. It's easy to defeat someone if they're alone and you shoot first. But how well will you do against multiple opponents?

Sure it does. Ask any actuary.

Yes. Games are, at best, a simplified abstraction of the world. That's why I'm such an average marksman despite playing first-person shooters my whole life.

Unless they do exactly the same thing. It's a perfectly symmetrical game, after all.

Close Bitcoin-Qt if it's running, copy your wallet backup to %APPDATA%\Bitcoin\wallet.dat, then restart Bitcoin-Qt. It is not normally necessary to run with the -rescan option, it should "just work" after you copy the wallet.dat file over.

I'm in.

The fortune isn't placed inside the cookie until after it's baked. A fortune cookie comes out of the oven flat and circular, like a regular cookie, at which point it's flipped over, the fortune is placed on top, and the whole thing is then folded up into the familiar shape (while it's still soft). Assuming they're not undercooked, they harden as they cool, leaving people like you wondering how they managed to get the fortune in there.

Who do you think you're fooling with that "hypothetical" nonsense? You certainly won't fool the cops with that excuse. I know you think this is a brilliant scheme that will save you from prosecution and you're amazed that nobody's ever thought of it before, but it has been tried before and it doesn't work.

Selling prescription medication is illegal in the U.S., and so is not allowed on these forums. It is also unwise, considering how badly you obviously need your medication. Please take your pills; they will help you determine which keys on your keyboard are letters and which ones are not.

Damn! These make mine look like crap.

If you didn't, then you implied that laptops have radiators instead of heatsinks, which they clearly don't. Although a heatsink can function as a radiator, it does an extremely lousy job of it. Almost all of the heatsink's surface area is in the fins, which are all facing each other, and so are radiating into themselves rather than into space (not that they would be radiating into space anyway, as the heat is blocked by the laptop's case, which is made of plastic, a poor conductor to put it mildly). The only thing a heat sink is good for is transferring its heat to a large volume of air before blowing that air away with the fans. And fans aren't known for their usefulness in a vacuum.

Volume is just the number of bitcoins (or shares, or whatever) that have changed hands in a given time period. On paper, anyway. If I sell you a bitcoin and then buy it back for the same price, that's BTC2 of volume (BTC1 for each trade), even though there's no net change to our position. So be aware that volume can easily be manipulated.

I recommend Economics in One Lesson by Henry Hazlitt. You can download it here (PDF, 1.3 MB).

The exchange rate (not just with bitcoins but with all currencies) is simply whatever price people are willing to pay, eg, if I want to buy a bitcoin for $100, and someone else wants to sell a bitcoin for $100, then we make a trade and the exchange rate is $100. If instead they want to sell for $105, then obviously we can't make a trade unless one of us changes our price. If I'm really desperate to buy, I might raise my price to $105, or if they're really desperate to sell, they might lower their price to $100, otherwise no trade will take place. It's really that simple.

The exchanges simply consist of many people all making many different offers, with buyers and sellers being matched by an automated system, eg, if Alice offers to buy a bitcoin for $100, Bob offers to buy a bitcoin for $101, Charlie offers to sell a bitcoin for $105, and Dave offers to sell a bitcoin "at market" (meaning "at the best price currently on offer"), then the exchange will automatically sell Dave's bitcoin to Bob for $101, without Dave or Bob actually having to talk to each other or do anything else.

Different exchanges will have different offers on the books, and this will result in slightly different prices, but only slightly, due to arbitrage. Arbitrage is when someone buys from a seller offering a low price and immediately sells to a buyer offering a high price. This has the effect of raising prices where prices are low (because once you've bought up all the cheap coins, the remaining ones are more expensive), and lowering prices where prices are high (because there are only so many people will to buy for a high price, and once you've sold to those people, the only buyers left are those who will only pay low prices). In this way, arbitrage causes prices to reach an equilibrium between different exchanges, and in practice the only reason you'll see a big difference in prices between exchanges is if something is making arbitrage difficult or impossible (eg, high fees making it too expensive to move money from one exchange to another).

In case you're wondering, all other markets (shares, commodities, foreign exchange, etc) work exactly the same way.

Do not pet cute animals in Australia. The cute ones will kill you. The non-cute ones will kill you too. In fact, just stay the fuck away from Australian animals in general. And some of the plants. Don't swim in the water, either. Stay away from the water. But not so far away that you're in the middle of the desert. You know what, if survival is a priority, visiting Australia is just a really bad idea.

When I first read the title, I thought the epidemic was of people who don't know the difference between "their" and "there". But I guess that other thing's pretty bad too.

You will get $105. When you place sell order for lower than the highest bid, it's filled by that bid immediately, and then the next highest bid if that's not enough (eg, if you were selling 2 bitcoins, you would get $105 + $103), and so on until your order is completely filled or there are no more bids above your price. Same thing if you place a buy order for higher than the lowest ask: the order is filled at the lower price. They're called "limit orders" for a reason: when you place a sell limit order for $90, that does not mean "sell at $90", it means "don't sell for less than $90". If you can get a better price, you will.

This also means that those who placed the outstanding orders don't get the best deal that they potentially could have. If a limit order isn't filled immediately, there's always the risk that someone else comes along later with a better offer and basically screws you over (though if the guy who bid $105 wasn't willing to buy at that price, he shouldn't have placed the order in the first place).

All other markets work the same way.
