Rejections is the norm for fringe ideas, even fringe ideas that work. (It's also part of being an entrepreneur)
Nothing to see here...move on.
Also the best things are often the most polarizing. For example, the iPhone. |

I don't know anyone in the area. There is a poster named Santa Cruz though and tradebitcoin lists a guy in downtown SF, but no contact info.
Downtown SF would be me. I updated it to add some contact info, and change my name to kelp. |

Thank you for your sarcasm, lightrider. Glad to know I'm not alone.
As for the rest of you savages, if you want to remain marginalized and howling naked in the far and barren hinterlands of the internet, beating your cryptographically hardened chests with your bitcoin clubs imbued of black magic, adorning yourselves around dim fires with alpaca, drawing golden ratios in the sand with your primitive calipers, feel free to do just that. Enjoy your lives far from Rome's glowing light, short and brutish though they may be. And in the far distant future of 2021, long after your sideline civilization has been dusted from the roiling surface of the world, a woman will walk down by the riverbank and happen to pick up a bitcoin buried in the sand, puzzle over it for a bit and throw it back into the flow of the water - a primitive token as useless as the ancient old "warriors" who used it, long dead now.
If you exclude the biggest portion of humanity from being pumped about bitcoin, don't be surprised when we all turn our backs.
Well said. Thank you. Sexism will not serve to push bitcoin forward, only hinder it. |

I'm in SF, I'd be interested.
And a suggestion, you might get more people seeing this if you post with a more descriptive subject, like "SF Bitcoin Meetup Interest?"

Isn't the 5970 the best mining card, due to the highest amount of shaders for lowest power drain?
That seems to be the consensus, but they are not that easy to find right now for a reasonable price. |

how do i run it on mac?
This is what I had to do. Download and install Xcode Install MacPorts from: http://www.macports.org/install.phpInstall the dependences for poclbm. This step may take a long time while it downloads and compiles stuff: sudo port install py26-pyopencl Download the sources for m0mchil-poclbm, from https://github.com/m0mchil/poclbmthen open a terminal and extract it, and give it a try. mkdir Bitcoin cd Bitcoin tar zxvf ~/Downloads/m0mchil-poclbm-b981138.tar cd m0mchil-poclbm-b981138/ python2.6 poclbm.py -d 0 -o yourfavoriteminer -p 8332 -u user@example.com --pass=something Be aware, that for what ever reason, OS X is FAR slower for mining than Linux or Windows. I run this on a Mac Pro with a pair of ATI Radeon HD 5770s. In OS X I get about 65Mhash/s on one and 95Mhash/s on the other. I installed Ubuntu 10.10 and boot into it through Bootcamp. There I get 170Mhash/s on each card, over 2x the performance. |

I'm getting a crash on Mac OS X 10.6.7 with m0mchil-poclbm-b981138. It doesn't crash with m0mchil-poclbm-74a5442. I've posted the stack trace here: https://gist.github.com/902241I'm running it like this: python poclbm.py -o deepbit.net -p 8332 -u <email> --pass=<password> -d 0 -f 120 This is with Python 2.6.6 installed from MacPorts. All dependencies were also installed from MacPorts. Anyone else running into this and found a fix? Oddly, now it's working fine for me with b981138. |

Difference between 4x 5870 and 2x 5970, power consumption. Almost 200w difference, even if the 5970's core will be OC to 5870 core speed the difference is still big. If your planning 4 cards on 1 motherboard, you should consider water cooling the cards.
Yeah, after looking at the numbers more, I decided that getting 2x 5970s does make more sense. IF I can get them cheaply enough. |

I agree that what you just wrote is utterly senseless and incoherent. But that is not what I said. A contract is an INFORMATION right. A contract is not the scribblings on a piece of paper, but the information content of that contract is enforcible by the use of physical force. Similarly IP is an information right. So they have something in common. The argument "I can do whatever I want with my PHYSICAL property as long as I don't infringe your PHYSICAL property" is what most libertarians use against IP laws, but the same argument can be used against contracts. In both cases you are refusing to acknowledge that information may be the legitimate source of physical force.
Again, this is a non-sequitur. A contract is an agreement between individuals, a meeting of the minds, as it were. Who cares? It's just information and I can do whatever I want with MY body so long as I physically don't harm you. Why isn't that a valid argument? Because you're making a false equivalence. It wasn't until 1989 that copyright was even implicit in the United States. That came with the ratification of the Berne Convention. IP laws are not inalienable rights, and they have been very significantly tightened, due to heavy industry lobbying, in the United States over the last 30 years, especially with several acts passed in the 90s. We had perfectly functioning contract law before significant copyright and other IP protections. The two are not inextricably linked. |

You win, I processed it now (damn my compulsive disorder). So everything is fixed, payments are automatic again. To monitoring: Do you really think that sms wake up ME? Definitely not  . I have some monitoring on the pool (including http status of site), but I'm usually unawakeable. That will integrate with several monitoring services and actually call you on the phone, over and over, until you tell it to stop or resolve the issue. It does require a subscription fee though. :/ |

If implicit contracts are not valid then this means that if you DON'T wear that sign one day, for some reason, then it is perfectly ok for anyone to kill you. They can simply say "I didn't agree not to kill him, and he didn't say it wasn't ok." Sane people understand that life would be unbearable without such implicit contracts, and copyright law is simply one of these implicit contracts. Copyright COULD be implemented with a sign on the book stating "by opening this book you agree not to spread the content of this book to anyone" or if that is not acceptable then even sign an explicit contract with the seller that you will not spread the content of that book.
In short, none of the standard arguments against IP leads to a sane world because of the logical implications it has for other laws and rights.
Did you really just argue that not having IP laws is a slippery slope to allowing murder? |

What PSU are you talking about for 150usd that will power 4x5970 safely?
We were considering 4x 5870s vs 2x 5970s, not 4x 5970s. nster suggested you could power 2x 5970s on a $150 PSU. When I'm talking about 4x 5870s, I'm looking at the Cooler Master RSC00-80GAD3-US, which is about $240. |

Yeah, I was looking at the MSI 890FXA-GD70 and the CoolerMaster HAF-X. That combo should fit 4 cards. But Motherboard + Case is $365. A cheap case + cheap motherboard could save $~250. If I could get 2 5970s for under $600 each, then I'd come out ahead on the dual 5970 system with a cheaper motherboard and case. Otherwise, assuming I could cool it, it still seems like the 4x 5870 system makes sense. And yeah, I understand I could save more by building super cheap cases out of various other things, but I don't think I want to make that optimization. |

I've been searching forums and IRC logs, along with plugging numbers into a spread sheet to figure out the best current GPUs to buy for a dedicated mining rig. But there are a few questions I just can answer without experience. I'm basing my performance numbers on the data here: https://en.bitcoin.it/wiki/Mining_hardware_comparisonBased on that, I think I could build a system with 4x 5870s for ~$1600 total and get around 1.4Ghash. Those cards are going for like $215 each now. That seems more cost effective than 2x 5970s since I'm having a hard time finding those for less than $650 each. If I had to pay $650 for those cards, I think the best I can do is around $1800 total for that system. I realize some cost savings by getting cheaper MB, case and power supply, but the GPUs cost 3x as much for 2x the performance!. And then I'm doing like 1.2Ghash? I don't see how the pricing adds up unless I can get lucky and score some used 5970s on ebay for a better price. (I did just see one go for $470 + shipping.) Unless the thing I'm missing is cooling. I haven't tried to build a 4 GPU system before. Is it going to be impossible to cool a 4x 5870 system that's running 24/7? Also sound may end up being a consideration depending on where I end up keeping this. Any advice would be appreciated. |
