lower fan speeds, which means your fans last longer.

Citation needed.
It's a known fact that running these fans at lower speed is better.
Running a normal GPU fan at 100% will ruin it

Tainting will likely happen after/when Bitcoin is widespread, I would give it 12-15 years.
Sorry if this is a stupid question (couldn't find a non-ambiguous answer anywhere) but exactly what is a tainted bitcoin?



A stolen bitcoin.

Like someone steal a bitcoin, well then this bitcoin is "tainted" and whoever receive it will like be "omg you have a tainted bitcoin you CRIMINAL" wich of course make no sense cause bitcoins keep moving from an address to another and if you sell something to someone and he pay you with a "tainted coin" you are not a criminal.

Not true. Tainted is not a stolen bitcoin, it's a bitcoin merely accused of being stolen, big fking difference.
Right, sorry, my fault

3087  Bitcoin / Bitcoin Discussion / Re: [Password Leak] LinkedIn database hacked on: June 07, 2012, 01:59:30 PM
is there only one unique string (password) that corresponds to a given hash?
Theoretically there are are infinite number of inputs that will result in the same hash because the hash function outputs a fixed-length value but the input can be any length.

Yes, thank you. Now, is this statement still true when a typical password is shorter than the 32-byte hash? 

For MD5: http://stackoverflow.com/a/2000014

Alright, does this mean that if my password is a reasonably random string, and the unsalted hash is made public, it may be possible to "reverse" it, but it won't be possible to tell for sure that that was the actual password - there could be another string with the same hash out there.

Also, does this mean that you could still type in a "wrong" password (that hashes into the proper hash), and you would be able to log in just fine, since server is ultimately comparing hashes?

Sorry for silly questions, I'm not versed in this topic but I want to understand the implications of these kinds of leaks.
Note that for SHA 256, 224, 512, 384 no collision has ever be found. None.

There is none. Yup, microcash is scamcoin with another name. Litecoin was a "cpu coin" but now it is not.
Also mining is not a "get rich quick scheme", in these days it's mostly done by professional people, maybe with FPGA and, in the near future ASICs

Given the extent to which coins are "tainted" on the basis of little more than unsubstantiated claims, I can see legitimate businesses choosing to avoid taking Bitcoin altogether rather than having to go through the hassle of dealing with potentially tainted coins which may be difficult to offload.

This thread actually reminded me of an obscure bit of trivia I once learnt. Namely: ordinary cash (to the best of my knowledge) is not actually 'owned' by the person/s holding it. The actual bits of paper are owned by the government (or the reserve bank that issued them. It probably varies from country to country -- not sure).

This is analogous to the Bitcoin situation whereby nobody actually 'owns' any of the coins on the block-chain. As proof, anyone can download ALL of them if they want. Their usage is merely governed by the rules according to which coins are transacted using the open-source Bitcoin protocol. Therefore, the casual, social concept of ownership is not even part of Bitcoin, and everyone who bought into the idea should understand that and accept it instead of trying to change it into a different system.
But you own the private keys for your bitcoins. Only you have that private keys.

Nothing is ASIC hostile. Nothing.
Go read again the definition of ASIC please  Smiley

It is my understanding that, in terms of cost-effectiveness, scrypt can be regarded as relatively ASIC-hostile.
Of course you could design a fast (relative to a desktop CPU/GPU) ASIC for scrypt, but because of the memory requirements of scrypt wouldn't it turn out to be way more expensive than a fast ASIC for, say, SHA-256?
No. There is no "ASIC hostile" things  Undecided It would be like saying "scrypt is computer hostile"...
Why it should be more expensive?

So you guys do not vote but then whine about the bad government that use force and violence? This is so fail, so fail.
Can you explain why?
Because if you don't even vote when you have the chance you allow other people to choose the government and it's nonsense that you later say "bad government"
Non voting=other votes for you and choose the government for you

It's useless to speak about anarchy and liberal id you guys don't even vote for what YOU want.

I hope you know that one of the basic concepts of litecoin was to try and prevent GPU domination of the mining activity.  Your gpu will not perform the same as it does on BTC.
And do you know that despite that litecoin runs VERY WELL on ATI GPU? Much much much faster than on CPU

As for btc vs ltc, everything depend from the price and the difficulty of them. But cpu mining litecoin? Fail.
