Erm, i guess i should've posted this on Economy or somthing, can some mod move this please?

To get the exchange rate between BTC and BRL for example, currently i first get the rate between BRL and USD (or EUR) and the rate between USD (or EUR) and BTC, and then combine the two rates; how can i get the the exchange rate directly without needing to use an intermediary currency?

A variant of this game that favors a more equal distribution, i dunno what it's called,  was somthing i learned when i was a kid, it works kinda like this there is only one big slice of cake left and two kids, to make them both agree it was a fair distribution of the end of the cake, you ask one of them to cut  and the other to decide which kid gets which piece, letting both know their roles beforehand.

With the guy receiving a lesson on not being too selfish we're one (small) step closer to having a world with more selfless people.

A while ago i saw on TV this thing about how according to the teachings of some religion (i think it was Muslim religion, not 100% sure though) charging interests when lending money to people was kinda like a sin; but then what happens if someone wanna lend an ammount in BTC, which medium and long term is expected increase in value?

Even if neither i nor anyone i know will ever meet him again, i still would find it gratifying(sp?) to do my part, even if it's small, in making the world a better place.

Check my thread on the topic (look for the one with "bitcard" on the tittle)

When deciding whether to take the deal or not, i would weightt my gains in absolute terms (ignoring the total amount that got splitted) versus how much my decision would teach the other guy to be a better person; if what i would be paid was a big amount, even if it was just a small percentage of the even greater amount that got splitted, i would be more inclined to overlook the unfairness of the split, but if i would only get paid a more insignificant amount, i would be more inclined to not take the deal to teach the other guy to not be so selfish; but on the other hand if the amount the other guy gets even after giving me only a small fraction is already insignificant, rejecting the deal wouldn't teach much, and even a small amount of free money is already better than no money at all, so in such circunstances i would be more inclined to take the deal anyway.

even without spending, just by having the wallet file unencrypted in your disk you are already open to the possibility of your money being stolen. Even if the wallet is encrypted, there is still the risk some malware might sniff the data while a program decrypts it to RAM. And even if you don't launch any program that touches the wallet yourself, malware could still do it unatended, if you saved the password for decrypting it that could be used, or the malware could transmit the encrypted file to the attacker's machine and the attacker could attempt to find the password using a dictionary and even a bruteforce attack.


There are all sorts of ways your coins could get stolen

You aren't moving anything, only adding precision

Perhaps with should be talking about short term and long term forks

I might have overstated my confidence a tad with my vote, but Bitcoin kinda works like the placebo effect, the more you believe in it the more it  actually works, so i'll keep my positive thinking.

slashme wonders if our dear Sattie knew Bitcoin would be his ticket to reaching mythological status

There is no place, like Utopia.

But if you do happen to produce a valid address, the money will be sent there, and whoever owns that address will get the money, if no one owns it, the money will be "lost"; there is a small chance someone in the future will create a new address that will match that typo, in that case, that person will "find" the money.

Since the sending of the money doesn't need to be instantaneous, how about a captcha system kinda like this:

You collect a bank of images, things like group photos, photos of animals, landmarks etc (perhaps simply by scraping the results of image searchs, taking note of the keywords used, and if the site the image comes from got tags for the image, take note of the tags too, ) .

Each time someone tries to request coins from the faucet, the server randomly picks one of the pictures, distorts it a bit, in a unique way each time, taking note of the way it's distorted to remap distorted corrdinates back to original; and then asks the person to click where in the picture somthing is (selecting what based on the keywords used to find the picture and associated tags if any; things like the front left headlight of the car, the nose of the cat, the tip of the Eiffel tower, the biggest digit in the picture, the face of the youngest person in the picture etc).

Remaping the clicks to the undistorted coordinates, the server then starts ranking the clicks in terms of how close to the average of the other clicks for that same feature. But  each time a same person refreshes or asks to try a different picture the weighting of their vote for the coordinate of the picture average is reduced, so if someone tries several times in order to find the same picture and being asked for the same feature, to try to distort the average in their favour, their attempt of tampering will not easilly outvote legit clicks.



Perhaps besides the geometric distortion, it might be good to also add other interferences, like hue, saturation and brightness noise and gradients, invert the color in small randomly shaped part, "burn" out little holes here and there, add a few blur gradients (kinda like randrops on the camera lens), overlay small randomly shaped patches with the colors "solarized", the resolution reduced (pixelazing the image) etc; basicly all sorts of image "filters" that would confuse computer vision, specially when combined, but (at least most of the time) still leave the contents of the image easilly identifyable by humans.

Detecting the split while it is happening and after the forks are being merged are two different things

Ignoring the obvious joke votes, it's forming a nice gaussian curve

I wouldn't consider it being beyond them to actually build farms with cheap purpose built hashing cards

Paraphrasing Budha, "to live is to suffer"; if you agree with that, then the obvious conclusion is that giving someone life is an act of aggression; you're making them suffer, suffering they wouldn't otherwise endure if it wasn't by your actions..... <.<
