You probably don't need more than 4 GB. Two 5850s with thread-concurrency at 7200 only uses 50 mb ram

it's bad because people can trick you into importing a private key. your client will show that you have BTC. but if it's not sweeped to one of your addresses, both you and the other party has access to the coins.

I used to download a lot of "err" files through torrents or p2p, until my ip started sending me warning letters to stop, until they cutoff my internet. So now I just try to do everything legit.
find some digitalriver windows 7 ISO links. |

- make sure your card supports opencl/cuda
- go to device manager, and make sure it shows up on display adapters
- get gpu-z and check that the card shows up on the list, AND the opencl/cuda boxes are checked
- run cgminer with enumerate device options to see if it's detecetable

keep in mind that setting -I too high will increase desktop lag, (may) increase number of stales, and (may) decrease hashrate. https://github.com/ckolivas/cgminer/blob/master/SCRYPT-READMEThe
reason this is crucial is that too high an intensity can actually be
disastrous with scrypt because it CAN run out of ram. High intensities
start writing over the same ram and it is highly dependent on the GPU, but they
can start actually DECREASING your hashrate, or even worse, start producing
garbage with HW errors skyrocketing. I run at -I 15 and I get no HW errors. |

it requires the AMD APP (or opencl) runtime only. SDK includes the runtime, but so does the latest version of catalyst.

Smart Batch 3 owners would re-sell their pre-order for truckloads of cash.
They aren't going for that much - their pricing where much higher just a few days after they went out of stock. Now, with BFL shipping (slowly), ASICMINER delivering units 3/4 days after purchase and preparing a new deployment, plus others players willing to enter the market, the enthusiasm is much lower. Add to this that there are still batch #1 customers without their units, and that not a single batch #2 customer has received yet a tracking number... And you will understand why the value of batch #3 preorders has diluted. I don't think you will get more than a 20% markup on one of those, and you would sell it to an anxious newbie. If Avalon suddenly starts to ship batch #2 with tracking numbers and promises shipping of batch #3 very soon... Well, then maybe you could unload your preorder with a 200% or 250% markup. is it even confirmed that batch 2 (or 3) will have tracking numbers? |

you do realize that for people with free electricity, gpu mining will always be profitable, right?

here's what i did to compile bitcoin-qt on windows 1. install vmware workstation 9 2. download ubuntu VM 3. create new ubuntu VM 4. install gitian builder5. use sipa's script to build bitcoin it's much easier to building on windows, and it builds windows executables in addition to linux ones. no need to mess with cross-compile. |

anyone can fork their own version, but good luck getting existing users to switch to your fork.

so not all transactions are the same size? are you talking amount of btc or the size in kb? how varied are they? what is the size, of in kb, based on?
transaction size are based on how much "inputs" and "outputs" they contain. in general, if your wallet's balance is scattered across many addresses, the resulting transaction will be larger. |

Here's what I wrote (I was limited to a certain # of characters): I've been trying to contact BFL (butterflylabs.com), but they have not responded. My order was charged before even shipping, and this company has been suspected of being a scam because they do not estimate when your order will be shipped, and people have been waiting for their products for over a year, with no proof BFL will actually deliver them, and PayPal is disputing with BFL to deliver. Pressure them to deliver or reverse my transaction. thx you lost all your credibility right there. Also, you got a huge run-on sentence in the middle. |

the one with the highest expected value? it's called NOT GAMBLING. mathematically proven too.

So if importing private keys is dangerous then what is the right way to spend money that is stored in a paper wallet? I imagined you were supposed to import the private key of the paper wallet.
you're supposed to spend the input immediately, so there will be no funds left over in the paper wallet. this can be done by using a separate wallet to send to your main wallet, or by using coin control to make sure the paper wallet's inputs are spent. |

that's called the private key. if you need more security, you can do multisig transactions.

awesome, do I use the same script you linked to above, and how do I run the program, do I have to take it into a compiler or is there an executable?
(I'm learning a lot of this as I go along, but I'm determined to learn it so be patient with me, I realize how stupid my questions probably sound.)
he says it's in C, so you'll need gcc, mingw or visual c++. |

If you'd be willing to use an escrow or middleman. I'd be willing to purchase. Otherwise, I have over $100k in trades on Sythe (videogame blackmarket).
proof? I highly doubt you traded $100,000 worth of games. (unless you say $13 russian keys are "worth" $60) |

If you are claiming that v0.7.x broadcast a transaction without being in sync, I'm not sure why that would be.
But this is really a moot point. Let the client sync and then your problem is resolved (or at least if there is still a problem, such as no connectivity, this can be properly diagnosed).
I sent two transactions via the out of sync v0.7.x, then I saw there was an update. After updating, nothing but problems. With ~15,400 blocks remaining / 92 days, it'll be a few weeks until it's close to being in sync. stop using 0.7.2, use 0.8 (it has faster sync time). or use a lite client. |

bitcoind provides API through json-rpc. just search for json-rpc code samples.
