Hi All; I asked this on the NOMP github and haven't received a response, so I thought I'd try my luck here. After installing Node.js v0.10+ and Redis key-value store v2.6+ I proceeded to git-clone NOMP. All went well up to this point, but when I issued the command npm update I got a fatal error. The only references I can can find to a similar problem have to do with not having ssl set up, which is not the case here. I've included the relavent details and error messages below for reference. I'm sure this is something simple, but for the life of me I can't see it, need a fresh pair of eyes I guess. I can send the complete log and std error/output files if you want them.

Suggestion for good power supply for s3  thanks I've got two over-clocked S1's running off a Cooler Master V1000 (stateside SKU=RSA00-AFBAG1-US). It has fully modular cable design and eight PCI-E 6+2 pin connections. Paid $209 USD new at the local geek shop & it works flawlessly, I would definitely buy another one. Has anyone heard when Bitmain might release the S1 --> S3 upgrade kit they talked about, at what price. Sorry if this was already answered but at 70+ pages I don't have the time - or attention span - to read the entire thread. Regards, JR |

BFL will have their day in court to defend themselves. Too bad Satan can't be called in as a witness.
[quote author = The Churchlady] Next witness please. Could it be ... SATAN!?[/quote] |

.... The name of this movie is called BitFellas....
 Ah, the delicate sounds of full-contact capitalism. |

Maybe Four, eventually; I would be more likely to buy S1 update kits at first. Any word on price/availability for those?
Regards,
JR

Agree with kabopar, I have 5 S1's and they're great little machines: wish I had 5 more. When the difficulty goes up to the point where you can't mine BTC effectively, start mining the better alts and get S3's or used S2's for the BTC work.
Regards,
JR

You sound like a witch
Nah, just a noob trying to understand the various critters & creatures that lurk around here.
It's probably because he mines at GHash, is why he's defending it so ardently.
I have 500 GH/s of capacity working at Polmine now, another 260 GH/s coming online next week, either solo or at Polmine and a WOPPING 68 GHS at CEX.IO. Hardly makes me their patron saint.  |

Purify with the sacred flame brother Mathias.....  Do you guys feel the same about Walmart, McDonalds, etc? Why, does Walmart and McDonalds attempt to double spend Bitcoins and execute a 51% attack on the network? AFAIK CEX.IO/GHash.IO hasn't launched an attack on BTC, nor expressed any such intentions. I can't speak to the double spending, other than to say it doesn't make sense for an exchange; Mt GOX implosion scenario, et al. RE: Walmart and Mickey D's; both have been accused using their enormous market share to drive smaller competitors out, through under-pricing; a fiat currency 51% attack, if yo will. I haven't heard calls for burning Ronald McDonald at the stake, nor expressions that its good to die opposing the construction of a Walmart. Why such rhetoric for CEX.IO/GHash.IO? Seriously. |

Death to ghash and its users
So Bitpop, when BitFury plows $20M of VC money into industrial-scale mining, will that be a good thing, i.e less total share mined by CEX.IO? Not meant to be a troll, I genuinely want to know what you think about it. Possibly they'll kill difficulty more competition That's kind of how I see it as well, which is why I'm having such a hard time understanding all the outright hate and discontent over what is likely a short-term condition. I suggested on another thread that the NSA was a bigger threat than CEX.IO & got outright roasted for it. |

article : Published on May 13, 2013
We're in 2014 right now:
I guess your name actually says it all "CTL_ALT_DEL" *poof*  Wow! So much vitriol over this, its hard to believe. ... Somebody asked me to support a statement I made RE: the NSA could take down BTC if it wanted to. In response I did an off the cuff estimate of NSA's computing power. I used MW consumption for an NSA facility recently in the news, an article on BTC hashing power and peta-FLOPS/MW for the Blue Gene Sequoia. Yes, the article I used was from 2013, newest I could find in a quick Internet search; Yes, the hashing power of the BTC network is substantially higher now; Yes, the Titan outperforms the Sequoia, which was 2013's top supercomputer; I suppose I could look at it from another direction but really, I have better things to do than try to guess the computing power of a darknet like NSA. Peace Out, Be Well, etc. and please do not hesitate flame me in future for being a newbie. I take a mind over matter approach to that sort of thing..... |

Current network hashrate is equivalent of 1189529.29 Petaflops. That's 60 000 of your Blue Genie computers. You do the math newbie The actual hashing power of the BTC network is 1039.79 peta-FLOPS. source: http://www.coindesk.com/bitcoin-network-out-muscles-top-500-supercomputers/Using a benchmark of aprox 200 peta-FLOPS per 65MW datacenter, three such facilities could launch a 51% attack on the BTC network. Math Done |

I didn't realize Exxon was mining now.
Given the disparity in capitalization, they simply could buy up all available BTC and not even dent their annual bonuses in the process. A couple of years on, BTC would be toast. Do you have some numbers about the hashpower the nsa has or you're just posting to let others you have heard a few conspiracy theories ?
An IBM Blue Genie/Q can clock 20 peta-FLOPS and consumes 6 MW of power. The new NSA Datacenter in Utah, one of many such around the world, draws 65 MW of power from the grid. Do the math. |

... Once people realize that the Achilles heel in bitcoin is real, they'll permanently mark it with a negative stigma.
The people for whom this is true stigmatize crypto-currency already; a 51% attack on BTC would not change many opinions, pro or con. Wow, I feel much better now. I can't wait for the pool operators to become the dirty dozen and begin "imposing solutions" on Bitcoin. Time to go all in. o_O
The total computing power of the NSA and its Five Eyes friends could take BTC down at will, the total BTC market cap is about 25% of Exxon's annual take and you guys are worried about GHash hitting 51%. |

....so I think it's about time to just let it churn away in the basement and leave the competitive sort around here alone for awhile.
At the risk of splitting hairs, you labeled this thread in terms of the "competitive sort", inquiring if there was some concerted effort to discourage said competition. I have no problem with that or indeed, anything you've said, but I can certainly see how someone reading it could misunderstand the question. Anyway, good luck in your endeavors! |

I think the disconnect is "small" vice "hobby."
I am a total noob, learning as I go, with the goal of turning this into a "small" mining operation one day: something from which I can draw a modest income. I care a great deal about Hashing power per KW, ROI at price per hash per difficulty, etc. As a "hobby" this doesn't apply IMO, because you don't care if your cash flow ever exceeds your operational costs, nevermind your cost of living.
Now when someone posts a question like "How can I get my 700MHHz Radeon GPU to kick out X KH/s for solo mining," it doesn't sound like they're asking from the perspective of a hobbyist: they want hashing power, as much as they can, presumably to maximize yield.
You really can't fault experienced miners who, when reading stuff like this, feel compelled to offer a dose of reality with thier advice.

I'm not sure I agree that there's an effort to "scare" anyone; rather, I think, people on this forum who've "been there, done that" are trying to pass along some hard earned wisdom.

If you are dead set on mining Bitcoin regardless of its profitability and/or are willing to purchase at least 250 Ghs of SHA256 mining power....
I have three S1's running 24/7, with a combined work factor of 540 GH/s. Exclusive of power my 24 hr ROI from pool mining is approx 0.003 BTC. Not bad for a 1,300 USD investment, but not likely to make me a viable business entity any time soon. A viable micro business plan would look something like this: At current difficulty you need at least 20 TH/s to average 1 BTC per day. Assuming you pick up used Antminer S1's off EBay and over clock them to 200 GH/s, that hash rate will cost you 300 USD X 100 = 30,000.00 USD. You will also need power supplies, switches, cables, etc to get everything up and running; again going to EBay, that's 300 USD X 50 = 15,000 USD for 800W power supplies and another 1,000 USD for switches, PCI and Cat5 cables. Ok, you've spent 46k on hardware, now you need a place to put it Retail space in a scary part of town will cost you maybe $5/SF/Year where I live, 4,000 USD per year for an 800 sqft storefront. The commercial rate for power is $0.07/KWh here, so your 40KW mining array will cost you 24,500 USD per Year. Then there's the difficulty factor increase: plan on adding a TH/s of capacity every quarter to stay in the game, an annual cost escalator of around 14,000 USD. Bottom Line: 46,000.00 USD initial investment + 42,500.00 USD recurring costs; est. annual income of 209,656.00 USD at current exchange rate (574.00 USD per BTC); minimum exchange rate for positive cashflow = 129.00 USD per BTC (at 10 yr amortization of initial investment). |

Yes on the board with the network connection on it you can find the little button.... The little black button, down and to the left of the red pilot light? I've tried that but it still isn't reseting. Do I have to hold it down for a specific length of time? Do I reset it powered or unpowered? Regards, James Rasmussen |
