Sounds like a great deal. I'll take it. PMing you.
Edit: gift card received promptly. Nice doing business with you.

Is there a such thing as tainted bitcoins?
I sure hope not. Having dealt with Visa/PP/etc chargebacks that stiff merchants, one of the key benefits of bitcoin in my opinion is their 1-way nature with no chargebacks. "Tainted" bitcoins just make more victims from an already bad situation. |

The problem isn't the pool payout-- the problem is that people participating in the pool end up with wallets full of tiny (e.g. penny-size) transactions. When they go to spend those tiny transactions, they're bundled up together to make a transaction that is small in value but large in size.
Pools can mitigate the problem by requiring larger minimum payouts (e.g. 1 BTC instead of 0.01 BTC).
Ok, that makes sense. Changing the pool payouts would mitigate it, but people could still end up with fragmented wallets for any number of other reasons. How about a feature in the client to consolidate one's wallet. It would bundle up many of the small wallets and send them to itself. I really dislike the idea of changing the rules at this point. |

This definitely needs fixing; it is another "people getting lots of very small change from mining pools" issue.
That sounds like the pool needs to do it differently, not the network. If this is a pool payout to 500 people in a single transaction, then the pool needs to break it down into smaller transactions. I sent a few regular transactions yesterday and they were immediately included in solved blocks. |

If you know what you are doing and can source the parts a dual 5970 can be built for under 1400.
What, using a bunch of used parts off ebay? 5970s are too expensive and hard to get to build a dual-rig for under 1400 using new parts. |

My customers who have .125 Ghps contracts get 3.45 BTC/day at the moment. 1Ghps at the moment gives 27.59 BTC/day.
And now with the difficulty at 55590.23763914, 1Ghps gives 18 BTC/day, at a cost of $23/day. That's about $1.28 per BTC, when the open market is selling them for about $.95. Kudos for finding buyers at such a premium price! |

With '-f 1' after a few hours it's definitely settled in for a nice hash rate. It swings maybe +/- 5%. Quite acceptable.
|

Ok, it's not crossfire related. Even with a single card my hashes are all over the map, unlike my other system. It must be driver versions.

Cdecker, how do you get the data for those graphs?
DiabloD3, "-f 1" definitely improves my hash-rate, but it still swings wildly. Typically between 300M and 350M, but also way below 300M from time to time. I'll try turning off crossfire and see if it improves.

With dual cards, my hash/sec are all over the place. It never settles in to a steady rate. (running locally)

This is the key point right here: every box is equal - checking 100 tickets from a new box completely compensates not checking 100 tickets from the previous box.
Due to the way hashes are essentially random, it doesn't matter if you switch before completing work. |

Wow, just pulled the latest commit, added my JMX patch and started the worker again and it maxes out at 14 Mhash/s on my 5850, whereas I got 254 Mhash/s before. Somewhere I got a problem ^^ I'll try to track it down next week  My 5770 was pulling about 15 MH/s until I set "-w 64", then it goes back to the expected 150 MH/s. |

Has anyone got this running with ATI cards? I'd be curious how it compares to Diablo...
The python-pyopencl package depends on the Nvidia drivers, which conflict with the ATI OpenCL drivers. So these instructions will not work on ATI. |

No, sorry. The Intel graphics you have won't work.

How about #bitcoin-dev on freenode?
|
|
|

if there are developers interested in joining the java library effort please tell me, and you can start judging the ugliness of my code, or start contributing. The goal is to have a solid base implementation on which to implement additional services and interfaces.
I'll take a look at it. Let me know. |
