I hate to be "that guy", but... Another one of these?
May I ask what you offer to differentiate yourself from the rest of the mining companies on the GLBSE?

I should be able to do the pot fallback, I'll give you an update tonight.
I'll also make it so you can just send a percentage without a group, which will set all of the fans to that speed.
I'm also looking into reading the tach. I'm going to plan on shipping it Monday.
Sweet. How do you want to be paid? If you want BTC, I'll need to move some funds around. |

You might be a scammer if your name is Tomatocage.
Are you sure you aren't mixing him up with the impostor account "Tomatocaqe" <-- note the "Q" where the "G" should be.... |

Raffles can only be done by charitable/non-profit organizations. In Florida, in particular, you can not require payment to enter any raffle. Some organizations get around this by asking for a recommended donation, but no payment can officially be required.
I'll bet that if you look into it, you will probably find that the law applies to raffles where tickets are sold for "money", I.E. USD. I doubt the government will give 2 shits about what they view as a raffle that is denominated in "internet funny money". |

As for replication, log or block shipping is preferable to rsync, especially if you don't have clustered storage management (ASM, VCS, etc.).
Yeah I'm partial to DRBD, and yes it would make more sense for a fast database. |

Those dozen or so black squares are the voltage regulators. They are directly contacted by the waterblock, it looks like. In air-cooled singles, they often have heatsinks on the back of the board where those VRMs are, as well.

LESSONS LEARNED:
RAID, dammit.
Daily full backup, and rsync only changes every few hours.
Spare hardware in hotsync, if there are a lot of users.
Prop hopping has gone the way of the dinosaur.

Whatever works, I'm not too fussed. I don't even know what the rest of the product line is like.
Is the plan for it to be manual control? Temp probe? Interface with cgminer? I don't really know what you have in mind actually, and I wasn't sure how crazy you were planning on getting with it.
Right now its manual control over serial. I think a probe would be a bad idea, and cgminer interfacing is something I haven't a clue how to do. I have an arduino uno on hand so that's what you'll be getting if you have no preference. You'll need to install the drivers for the emulated serial port over USB: http://arduino.cc/en/Guide/HomePageIf you have any requests for commands, let me know. Right now I'm thinking something like <fangroup>,<speed in %> which would look like 1,77 I could also make some handy features such as the allowance to spin the fan at light speed, or even ludicrous speed, so the command would look like 1,lightspeed As long as it is controllable via some software mechanism having someone else right up a program which checks temps over cgminer API and issues changes to fan controller over the serial port. Just keep in mind your connections need so be very solid when turning off the fans if you need to get in and tweak some hardware or something, because pwm 0 = 100%!
LOLZ. Good safety tip. I would imagine (hope) he is using safety grills. Back in my hardware days I remember changing out the hot swap fans on IBM servers. For some reason they had no safety grills not even cheap plastic ones. I never lost a finger but it always scared the crap out of me. The same server supported hot swap CPU and memory too but we never used those features. No we shut down the server to change those out but who cares if a the tech loses a fan right?  Yeah I got some fan grilles on ebay. So who might be able to write up a cgminer API interface, and what would it cost me? Oh and I just remembered - If I have several VMs with their own instances of cgminer, then what happens? I guess I could run some software in another VM to gather the stats or something. Also Garr255, if it isn't too hard, the only feature I need you to build in is an input for a potentiometer that controls them all in sync. This is so I don't go deaf when the OS isn't running. Either that, or when it doesn't have a serial signal, all fans go to 10 or 20%. |

Well, if I were to assume 300 watts per overclocked 5970 (not sure yet on 7990), x 17 slots == 5.1 KW of heat. I was looking at this rad from Grainger:  It's good for a little over 7KW, (10 horsepower) with forced cooling (8 HP with no forced air, they say). But it takes up 8U or so. |

If I watercool, then I need the depth for manifolds, hose, and other apparatus, so the PSUs would still have to stack, but all of it could probably be crammed into 6 or 7 total U. As much as I would love to have a package system, I doubt I could fit an appropriate radiator and pump into that space, so it would probably have to be external like DeathAndTaxes' setup. BTW, has anyone actually done any long term tests with more than 2 watercooled cards directly adjacent to each other without a second slot in between? The more I consider it, the more I am sure it would be prone to failure, unless they weren't linked directly to each other. If that were the case, I would have to use right angle connectors on each and every card, and that would get tedious, real fast.
you can have gpus watercooled in adjacent slots, you would need these: http://www.frozencpu.com/products/10744/ex-tub-669/Bitspower_SLI_Crossfire_Crystal_Link_Tube_Set_-_2_Slot_Spacing_BP-CLTAC-S2.html?tl=g30c101s873#blankhttp://www.frozencpu.com/images/products/main/ex-tub-669.jpghttp://www.frozencpu.com/images/products/main/ex-tub-669_2.jpgplus the fittings. all of these can be found here: http://www.frozencpu.com/cat/l3/g30/c101/s873/list/p1/Liquid_Cooling-Fittings-Accessories-SLI_Connectors-Page1.htmlI know it says "sli" connectors, but in reality its just a piece of tubing with the appropriate adapter. if you want a self contained water cooling pump, reservoir and radiator that is capable of being rack mounted take a look at: http://koolance.com/index.php?route=product/product&path=0_28_42&product_id=1173 http://koolance.com/image/cache/data/products/erm-3k3ua_p2-700x700.jpgHey sweet, thanks, I'll look into that stuff. |

Just a little update.
Jason is working on the different modules, going fast forward to prototype building.
Company registration is also in process, next week all paperwork must be finished.
Awesome, I like the way this is going. |

Edit: In short, couldn't you simply have a computer take the hashing algorithm, process it offline, save the results of the work, connect to the network, then dump all the results at once?
Blocks are linked. You need the previous block to calculate the nonce (which includes a hash of the previous block). Thats why you cant mine offline for longer than ~10 minutes. After 10 minutes you are essentially forking. ^^ This answers te orignal question. May I ask what is your goal? Are you trying to save bandwidth? Looking to 'mask' the reporting daemon? Trying to minimize net exposure? Well, I may have access to 2 T/hash under certain conditions, and hashing offline may be one of those conditions. I'd be interested in whatever came of this... MysteryMiner? |

Bump. What happened? Can't reply cause you are in jail?  Or did we ever get some video of this? Not in Jail, haha. The book is still intact. My Army buddy gets back April 12th. I lost track of what we were going to do with the book, but we had some pretty good ideas. I need to get rolling on this, haha. Man... this topic still exists lol
Well there are only so many ways to kill it Necrobampin' |

It's just a collection of website scrapers it seems, nothing that pool hoppers didn't have a year ago too... nice work nevertheless but of limited usability (and cheating pool operators won't be pointed out by this).
Actually, I've found it to shown some insight into "cheating" pool operators. Look at ecki, they find a block from time to time, but their data is never correct - every time another pool found the same block - pools I know that are not incorrect... How superbly interesting. Great site btw. |

Don't forget : flood my bitcoin-otc profile with -10 ratings from your sockpuppets so I cannot scam anyone on there too !!!
I need to get my profile all SCAMMED out folks !
Wow, going full retard on this one. Can't we ban him already? It's beyond tiring. |

In other news, I just confirmed a suspicion that not all the slots may be useable. Fortunately, only one of the 18 slots won't work, not 2 like I had previously thought. This is because the slot nearest to the SHB doesn't actually connect to the 2 main fanout switches on the board - instead, it routes to the x4 connector that is adjacent to the host board, and that x4 connector is used for an optional extra daughtercard that attaches via another connector to the SHB. Even if I had that expansion card and could plug it into the current board, I'm not sure that the new board (arriving Tuesday) will have that expansion capability. So as of right now, 17 useable slots.
Additionally, I've been thinking harder about a rack formfactor, and how to achieve it. Basically, the 2 main constraints are a maximum case width of about 17 to 17.5 inches, and a maximum depth of about 27 to 28 inches. Vertical space in a "normal" system that uses this board is 4U (7 inches), but this system isn't normal.
If I aircool, I need 2 levels of GPUs, so rack height without PSUs is 6-7U. PSUs might be able to fit into the depth (they are about 12 inches deep), but the fans in them blow the wrong way, and the power cords would then be coming out the "front" of the rig, from a rack perspective, which is awkward. If standing up, they need 3U, but turning them on their sides buys me 1U of height.
If I watercool, then I need the depth for manifolds, hose, and other apparatus, so the PSUs would still have to stack, but all of it could probably be crammed into 6 or 7 total U. As much as I would love to have a package system, I doubt I could fit an appropriate radiator and pump into that space, so it would probably have to be external like DeathAndTaxes' setup. BTW, has anyone actually done any long term tests with more than 2 watercooled cards directly adjacent to each other without a second slot in between?

April 29th and I haven't seen him ?!?
*Gasp!* What a surprise, usually he is so punctual! (I pulled that last bit out of my ass, obviously) |
