First of all, do a bit more research. If you are specifically referring to the Butterflylabs Rig Box product, the stated cost is $30k, not $20k. The hash rate and power usage claims have also been adjusted since its inception to more accurately reflect real world performance, based on actual performance of the Singles.
It is much less likely to be a scam than you are assuming in your first post. Again, a little more research is in order.

You should sell those obsolete 5970s. Better hurry though before word gets out how noisy and ancient they are.
Are people expecting the secondary market to be flooded with GPU's once singles are being easily accessible? I believe gamers are really going to enjoy this... And all the miners with free power and cooling. I'm surprised at how many there seem to be. |

Meanwhile, overall network hashrate is still slightly down, deepbit is still at +40% average block length (bitminter possibly even worse, havent calculated) and MM is still mining one block after the other. If this keeps up for a few more days, I no longer believe in coincidence.
I'll bet the simple explanation is that he has compromised some or many machines that used to be mining already, but for other pools, and forced them to mine for him. Hopefully it isn't a miner software vulnerability. |

kk right now i got it mining on 4 out of the 6 cards, if you look at gpumon from the system it shows it is mining, but if you ssh to it, it shows the "o protocol specified" messages like the above picture. if you open firefox and type in the IP, the interface shows that the system is not mining but it is actually completing shares.
It is actually saying " No protocol specified" but the linebreaks are screwed up. See the "N" at the end of the previous line. |

But it's fucking fast flash! Say that 10 times fast.  |

p2pool.. supports merged.. im doing it now.. read the faq y0!
Read again. It supports "merged" in the same way as solo-mining. Only one p2pool user gets the entire 50NMC block reward and it isn't split. And if you want to talk about pool size, I dunno why you aren't discussing Derpbit. Much larger. |

I'm stuck between ordering a couple BFL singles or just waiting for the 7990. Grr..
7990 of course. |

And really, if you use 4GB sticks of the cheapest ram you can find, a 1TB Ramdisk can be had for just $4,600!
I miss those ISA (!!!) cards that would take DRAM and create ephemeral storage. I wonder if those still exist or if everyone has gone down the MLC/SLC SSD route such as FusionIO for performance. For best overall, you'd have a RAMdisk pool with journalling to a high-speed SSD over a PCIe/Quad Infiniband/FC/etc. bus with replication to persistent media managed by another controller. Of course, you're still putting the SSD in the equation, which I only do at the workstation level in RAID 1 or 10 config, or as a cache for a larger spindle pool. The failure rate is still too high for the capital and infrastructure commitment. Here: http://www.violin-memory.com/ |

UpdateWell as you can see we tried to run purchases this morning but the additional load plus more and more miners coming online has maxed out the write speed of our current hardware. The good news is that new servers are being adding to the cluster as I type but takes time to get online. In the meantime offline mining causes no issues to the system so we are going to suspend purchases until these new servers are online. For those that have a purchase in the system, we can either refund your purchase or just let it sit in the system and ready to go when we turn back on purchases. Please email support@gpumax.com if you wish to receive a refund. Thanks, Step 1: Get a box with 1TB RAM Step 2: Setup tmpfs to hold everything Step 3: Profit! (and hope the box doesn't crash taking everything with it)  It's not the ram that you need it's the write speeds of the drives. The new servers have gone all SSD! I know, that's why I mentioned a ramdisk (although not in so many words) SSD FTW. They rock for high speed databases. |

Theoretically if you could intercept traffic going in and out of the pool's primary hosting provider, you could slurp up all the shares being submitted, but that wouldn't do you any good would it? the getwork that the pool is providing the miners is based on the pool's preferred block header, which has their address and such in it. Even if said attacker could "steal" the block, it would still pay out to said pool...
I may be mistaken in this, but that's how I see it from my understanding of how mining works.
Correct. However, if you can intercept shares in such a manner, you could also just provide your own work with your own bitcoind. Most users wouldn't be able to tell the difference, except that they would not be getting a payout of any kind from the pool. |

Oh sorry. I'd only looked at it a day or 2 ago when it looked like it was going up. Seems to have dropped since then. |

To get this back on track...
Thin foil hat scenario; deepbit is having terrible luck (down -33%), so do some of the other pools Im looking at (bitminter for one, its also down by 30% at least). At the same time, mystery miner seems to be increasing his output (5 out of the last 20 blocks!), and the overall network hashrate is going slightly down, not up as youd expect if this is LargeCoin.
Is it somehow conceivable mystery miner is "stealing" blocks? Sniffing network packets? Bitminter and deepbit are hosted by the same company I think.
Wow, no I doubt it. And according to Sipa's graphs, the net speed is indeed increasing. |

Second payment out to slush, 3.60 BTC

quit feeding that morbidly obese pool.. you should donate that to p2pool to help support and promote its decentralized nature! Wait, what? Morbidly obese? Yeah, fuck you too. It's not enough to get 3k coins stolen, but then you have the nerve to attack one of the most stable and innovative pools available. Tell me: does p2pool support proper merged mining with distributed payouts yet? No? Is it easy to set up compared to a regular pool? Get a clue before you shoot off your idiotisms. |

I want my BAMT charts and graphs  Hi rjk, The latest BAMT v0.5 with all of the fixes has cgminer compiled with BFL support. I donated heavily to also have lodcrappo fix up BAMT to recognize singles. You can have your BFL singles and BAMT too! Cool, I need to get around to trying it. |

Btw, you can abort work, but then it won't report good nonces found during that round?
Correct. You may also wish to look at Ufasoft's sources to see how he implemented plug-'n-play functionality - right now with cgminer you need to specify each device, but with ufasoft they can be hot-plugged. |

How much in BTC for 8 of them? |

MtGox will sweep any coins out of the address when it is added, and will keep it for future use and sweep out any coins added later. The coins are sent to a new address and credited to your account.
So if I import a private key, I can use the address forever, and whenever someone sends money to it, it goes into my Mt. Gox account automatically. Right? If you import it to MtGox, I would not recommend that you use it in your personal wallet. However, yes that is how it works. You may wish to send a satoshi to the address first before importing it, because I'm not sure whether MtGox will import an empty key. |

for a large chain, i support CAN or RS485 for the linkage specification.
Not a good idea in my opinion. RS-485 is the same old-school as RS-232, it is slow (115200), unreliable, etc, but it may be kilometers long (at 2400 baud, this option definitely not for Icarus  CAN is definitely faster and reliable but is very complicated, I've worked with CAN node programming about a decade ago and it was a hell. And both are not supported by Raspberry Pi. All we need - fast synchronous addressed shift register (SPI). No overhead to FPGA design, easy to implement and debug, also we will reduce overall rig stale rate due to fast syncronous data exchange between master CPU and FPGAs. And Raspberry PI has 3 SPI ports (I hope it is true). RS-485 has more than enough speed to support bitcoin mining, and you can daisy-chain it fine. CAN bus sounds interesting, but I dunno how well it would work with all the devices chattering at once. |
