I know it's not mining hardware, use it to upgrade your mom's system for mother's day.  I'm going to give it a couple more days and list this stuff on eBay. |

I'm interested in your GPUs.
They aren't "mining" GPUs - they're 2D workstation-type graphics cards in the nVidia Quadro line. If you're still interested I'll send along model numbers/specs. For any interested parties, since I'm discussing the GPUs, the DDR2 RAM I mentioned is 1GB sticks of varying speeds. |

Both CPUs are guaranteed not DOA (buyer pays return shipping if there's a problem, will refund BTC upon receiving), shipping is free in the lower 48 states (contact me for shipping costs to other locations). I've been buying and selling on eBay for over 12 years; if you'd like to see my seller feedback, let me know.
intel E6550 Core 2 Duo CPU, SLA9X, 2.33GHZ/4M/1333 22 BTC
intel E6850 Core 2 Duo CPU, SLA9U, 3.0GHZ/4M/1333 36 BTC
Prices may change to reflect currrent market value, but they are also OBO. Post here if interested (or private message me on the forum for payment address/your shipping address), I will post pics if need be.
If this goes well, I have some other hardware (DX10 GPUs, DDR2 RAM) I might be willing to sell for BTC.

How does Bitcoin work?
Bitcoin utilizes public/private key digital signatures (ECDSA). A coin has its owner's public key on it. When a coin is transferred from user A to user B, A adds B’s public key to the coin and signs it with his own private key. Now B owns the coin and can transfer it further. To prevent A from transferring the already used coin to another user C, a public list of all the previous transactions is collectively maintained by the network of Bitcoin nodes, and before each transaction the coin’s unusedness will be checked. In addition to hashing out new blocks, all of the transfers on the network need to be verified - so that's what your client is doing. |

Just ran Malwarebytes, bitcoin did not show up as a threat.

It's not conclusive at all, but I have the official bitcoin client installed on this laptop and I just ran Malwarebytes. It was not detected as a threat.

at least no one in that thread thought cash was backed by gold.
I wouldn't be so sure about that... |

That's my thread!  I look at it this way, most [H]'ers fall into one or more of these categories: minor/teen/early 20's (didn't we all know it all then?), unemployed, live at home, no world experience, etc. I don't really hold their skepticism against them; they know not of what they speak. |

I just noticed this - the date reads a month in the past in the CPU miner. Is this a problem on my end? My computer's date/time are set correct.

I believe you are correct, the confusion was all on my part...I'm a rookie.  |

FYI, I noticed two failed blocks yesterday on my GPU miners.

What miners do is so basic that anyone with a bit of programming knowledge can have at least a coarse idea of the task being done by looking at the code.
This is the main problem - they don't have any programming knowledge (caveat: neither do I), and they are also rather closed minded. This is all determinable by looking at the source code, btw. You don't need to believe me. That's nice and all, and I do accept that since it is open source there is no hidden agenda, but trying to get these people on board is mind-numbing. One poster likened bitcoin to money-laundering by selling IEDs.  |

I've only been mining a couple weeks now, but with two GPUs and two CPU threads going I've amassed some coinage. I posted on a popular forum's distributed computing section what everyone thought of bitcoin and I've received some troubling replies. The one that gets me the most (and the one that I can't seem to find an answer to) is this: just what is all this hashing for? Is it really merely to find the next block, are we unknowingly cracking for some devious entity? It would appear that they will not accept the former as an answer, even though they all run F@H and WCG clients and can't truly trace the math they are doing either.
