One of my cards that I replaced with a new 5970. This card is complete with box, cables and (outdated) driver disk. This card was run at stock clocks (except memory which was lowered). I may have a second card available as well. Not sure if I can find the box for it though! I will ship international at additional cost.  |

Software upgrades on pools??

cant we just sit wait for the coins to move and follow them everywhere they go? if the go and pay for goods ... ask the merchant where he shipped to. compile some evidence, and then egg his house.. or something How would you know an address was a merchants if they used unique addresses? If you knew that it was a specific merchant, how would you know the ship to was not a diversion like a public member of the community? |

Mitigation summary:
1. encrypt and backup your wallet in the client by default and add multi-sig transactions to the protocol
2. decentralize mining ASAP (encourage use of p2pool, integrate p2p mining in client, etc)
+1 There is essentially a bounty out there in the form of reward for theft for problems related to both the client and protocol. The main areas that need tightening are the pools because they concentrate so much power. Most all of the possible attacks would REQUIRE a pool or more money (in hardware) then the attack would capture. |

Everything depends on location and subsidies. In some places there is enough sunlight to make things ideal, just as in some locations there is ideal wind. Most locations do not have both. Right now the most cost effective is solar for small users, and wind for big users. Small wind turbines may work, and their owners may love them, but they scale down pretty poorly. The maintenance on the smaller ones is much greater then on the bigger ones. They really need to be on a very tall tower to work well, so unless you are in an unusually windy location they are a bad idea.
Solar keeps coming down in price and in the USA where your power is over 20 cents a KWh, you are in a sunny location, and there are 20% greater subsidies you should consider it. It is now greater then a 6% return, and if the money is not borrowed and would have been in savings it acts as 'tax free' income by replacing a post tax expense for most people.
So if you are in southern CA and have the money already it is a good deal for solar.
I am sure if you did the math, and related this to mining, you would be better off buying FPGA equipment to save power, vs solar to generate it.
For the Baltic sea area I would say buy FPGA unless there is a big subsidy and you are in a windy area.

I would do a data recovery attempt for you. The most important part, as others have said, is to STOP using the computer right away. Each new bit of data or even system restore attempt could wipe out your wallet from the hard drive. Even after you deleted the profile, the data was on the hard drive, windows just didn't know about it anymore. The odds are 50/50 it is still there.
I would do the attempt for some of the recovered coins, with no charge if no recovery.

Almost all short blocks my payout is 20% less. I am not quite sure why, am I doing anything wrong or is this something to do with pool hoppers?

When I price these items I check eBay for completed listings. 6990's go for $600 all the time. I take off 10% and try to sell here. If I can not get my price I put it on eBay and get more.
I sell about half my stuff here at the discount and the other half on eBay.

I sold a legit iPhone 4 here a month ago.

Bump as others are selling them for more.  |

hard to say as no one has them yet, but I imagine 20% less or so from the 7970s.
If they can not be unlocked, they should be able to do 90% of a 7970 with overclocking. The fan systems are quite variable looking between those cards, and the reference fan design on the 7970 is hard to beat so clocked the same the 7950 could get hot. As normal, AMD is figured out a pretty comfortable spot to place its 'neutered' version of the XX70. |

You can apparently order a new one sent to your address without sending the old one back for far less money. Do that instead.

BTCmon is the best! I love how fast I can check on my miners and the exchanges. It has a very clean look as well.

...or the PCI-E slot.
Agreed. More likely the slot then the card. |
