I'm still paying 0.33 USD because it can be hard to find cities without my ad in them  I might be interested, shoot me a PM with current information/rate/where you need the ads. |

However, hashing isn't actually a FLOPs operation. The network doesn't really do floating point calculations.
You are correct, but it's the closest equivalent we have data on. FLOPS roughly kinda sorta correspond to hash speed. |

From everything I've read thus far, pool mining isn't always the best way. It sounds like if you can attain a certain amount of mHashes/s (5000?), that would be good enough for solo/private pooling. Is this a correct assumption?
Well, it depends how much variance you can tolerate. When solo mining, you might solve the block in twenty minutes, or you might solve it in two years. |

The number Bitcoin Watch gives is remarkable if it has any basis in reality. I am just looking for a way to verify that it has a basis in reality.
Well, videocards contribute the vast majority of FLOPS to the Bitcoin network. You can look on this page to see the FLOPS of AMD videocards, which are the most commonly used for mining. Maybe Bitcoin could do a card survey to figure out who has which cards, and then it would be trivial to calculate FLOPS. |

Whatever is on the otherside of the link it doesn't matter, most people have already made their claims.
I'm talking about getting into our accounts again, "logging in", checking everything, seeing what happened to our accounts, etc.
Sorry for linking you to the wrong thing, just trying to be helpful. Mt. Gox will probably not be open for full business for at least another day. Just spam the F5 key on their site. |

I've used GUIMiner. Tried using the OpenCL? default miner and it gives me the same mh/s, so i'm thinking the GPU part of it isnt activating. I tried a CUDA miner and it completely freezes my computer after a bit, and corrupts my bitcoin install at the same time =(
Huh. Try updating your videocard drivers. |

Bitcoin can retain value without exchanges only if it's bootstrapped to the point where you can easily buy a lot of mundane goods and services with it, like you can with ordinary cash. Exchanges are a necessary part of that bootstrapping process. In order for Bitcoin to take off as a medium of exchange it needs to be socially accepted as well possessing theoretically attractive properties like durability and scarcity. Precious metals have certain theoretically attractive economic qualities, but try finding a business near you that will sell common things like gasoline, diapers, or hair cuts in exchange for grams of bullion instead of cash, check, or credit card. Bitcoins don't even have the survivalist justification that they'll retain value in a post-apocalyptic society. They need to be useful as a medium of exchange, and that means getting acceptance from a lot of people. Exchanges bridge the transition: a businessman doesn't have to hope that everyone else simultaneously adopts Bitcoins, because he can accept BTC and get USD or EUR to deal with employees and suppliers until there's a large enough network effect that BTC is commonly accepted.
Yes, and I think that is what Bitcoin could become. My point is not that we do not require exchanges now, but that they are not required for all currencies and may not be for Bitcoin in the future. |

Right but even compared to other distributed computing projects Bitcoin is huge. The largest other project that I am aware of is BOINC and I believe it still only has single digit petaFLOPs at its disposal.
Well, I think they're into double digits now. It was 5.1 petaFLOPS avg. on April 21st, 2010 (see here). By now it's probably into the low 10s, but nonetheless, Bitcoin easily trumps BOINC. |

I'll do some more testing later tonight when I'm back home. I'll apply the various suggestions from this thread and make a nice little grid to help define and furtherr isoloate the issue.
Anyone here have any experience on what linux will do if the video cards overheat? In this case, two 6990's at times reaching maybe between 80C to 90C...either for a few moments or for sustained periods of many minutes.
That is too hot for sustained use. You need to leave fan speed on auto. I'm not sure what Linux will do, but it could be what you're experiencing. Sometimes, regardless of OS, the system will just freeze up. |

My bad, I definitely meant the 8400M
It's all good. I don't know why Phoenix would be crashing. Try using GUIMiner, get it here. |

Hey guys. New to bitcoins. I find the whole thing amazing + awesome + etc etc etc...
The only problem is, my crappy processor gets 3.5 mh/s and id REALLY Like to use my GPU to help out... problem is , every time i run Phoenix or Diablo it crashes my display driver and nothing gets done.
Any ideas? Im running an Nvidia 8500m. The specific errors are...
Phoenix:unhandled error
traceback...
file threading.pyc line 504 in boootstrap
file threading.pyc line 532 in bootstrap inner
threading.py line 484 in run

pyopencl.logicerror: clenqueuereadbuffer failed: invalid command queue
DiabloMiner:
way too much spam on this. Lots of "failed to queue read buffer error -1 and -36.
Um, there is no 8500M. (see here) Maybe you're running an 8400M or 8600M? |

anyone knows whats going on with this ?  Try re-downloading and reinstalling. (but make sure not to delete your wallet.dat) |

There is not unlimited funding to invest in BTC, nor even in the stock market. Apple stock is $350/share, Google stock is $550/share. Stocks can cleverly split when the price gets too far out of the range of what middle-america can invest in. Not so with bitcoins, they just use fractional amounts. People will have a built-in antipathy to spend $10 on .01 BTC.
First of all, you're taking world demographics into account, not demographics of Bitcoin investors. Most of us have much more than a thousand dollars. And while people do like to get "more", the antipathy to getting less for more has already been passed, when the price went over $1 USD/1 BTC. $whatever USD/.01 BTC is no different. |

That is where you are wrong. Since the currency is decentralized, a stable price comparison to the USD/EUR is necessary (whether you like that or not, these two currencies are paid as wages and puts food on people's tables).
Without a price comparison you can mine all you want, but why would anyone sell you a laptop, computer hardware, clothes or anything else, if they dont know themselves how much food they can buy for BitCoin or how much wages they can pay their staff.
We NEED an exchange. We NEED a value, and such thing is what we dont have after the Mtgox incident. Without a price, there is no trade. Without any trade BTC has no value.
Money intrinsically exists without value. It only has value if people accept it as such. Bitcoin is no different. USD are no longer backed by silver, gold, or any precious resource. Bitcoin can retain its value without exchanges, though I agree at this point they are helpful. |

Yea well this data damaged the community a lot cause money, value was stolen. Previous Lulz hacks didn't have this effect.
The hacks that took down CCP (EVE), Minecraft, and League of Legends didn't damage the community? I don't know what news sources you read, but they must not agree with mine. Anyway, Lulzsec, I think, is unlikely to cause serious harm to the Bitcoin economy, though I have no doubt they could if they wanted. They take donations in Bitcoin, and generate quite a bit of revenue that way, so if they took out Bitcoin, or at least destabilized it, it would hurt them a lot. They're just having fun. |

will today we get our accounts back?
pretty please??
You can get your account back here. |

First, I must warn you that while I have some experience with Linux and Ubuntu, I'm no expert, so don't take what I say as fact.
You could try disabling any power-saving settings, but it seems to me Ubuntu is crashing somehow. Try setting fan speed higher, the 6990s need a lot of air throughput. You could be seeing the Linux equivalent of a BSOD if your cards are overheating. Also try just running Linux for awhile without mining, and see if the problem occurs or not.

The top supercomputer in the world has processing power of 8.162 petaflops, see here. It's a lot easier to generate computing power with a distributed network than one computer. That's TeraFLOP/s..
No, he divided by 1000. Metric prefixes are confusing, but he is correct. |

Hi,
In the GuiMiner, when mining solo at the bottom of the window there is a status screen that usually reads something in the lines of "Difficulty 1 Hashes 3". The hashes number increased from 0 to 3 over time,
but what does that actually mean? What does it mean when the number of hashes increases? And does Difficulty 1 also change?
Finally, how will the Guiminer know where to send my coins once it has found a block? Does the bitcoin client/server software tell it?
Thanks!
Are you solo mining or mining as part of a pool? |

Okay, answers to your questions: 1. Use GUIMiner with Ufasoft's SSE2 CPU miner, get it here. 2. Solo mining will get you nowhere. You'll need to mine in a pool, like Deepbit. 3. As for parallelism, I would just run one worker per computer, Ufasoft's miner scales nicely on multiple cores. |
