Just for fun I tried to search for their patents for this sweet cooling tech and their strip LED lighting from the future.... Take a guess what I found? Zilch  Then you did not search very well.... there IS cooling tech available to cool without Peltier or compressor. (start with :Stirling cryocoolers ) A Japanese company has a system where you have a sealed canister and stir a liquid and it does indeed produce significant cooling at one end of the device. The reason I know this was I was asked to 'design' a wine cooler/ Refrigerator that did not use any of the conventional methods. Problem was the licensing fee was massive and you could only buy units from the jap. company. So I would not discount the cooling tech.. however even with the cooling tech, there does not seem enough room in the case for the number of chips needed. |

Redirect mining power to support the superstition that is religion? Yeah, right. you know... that might just work... I could sell an exorcism service where I guarantee the possessed 200MP/s (Mega prayers a second), by taking bible verses and hashing them. The Hash could be the proof that the prayer has been processed.. something like $1USD for an hour So... 1GP/s Would be 5*24 =$120USD a day.. which is way more profitable than bitcoin mining.... |

Er...... But yeah, I don't feel scammed in anyway, as Wilson never promised me 1 Ghash, he promised me cheap FPGAs and I got them So I wouldn't call this a complete BS, as really even cgminer is just estimating against the number of shares sent per minute as cgminer cannot get the actual rate from the FPGA (this is a verified claim) And just a quick point...... the shares can vary WILDLY depending on the block you are currently mining, one of my miners swings from 1.7GH/s to 2.7GH/s basically a 1GH/s swing and yet the actual board count and frequency remains the same...... So if I wanted to sell , I would do a screen shot at around the 2.7GH/s mark and it would be completely valid, even though I know the base average is about 2.1GH/s |

Garage or shed is the place for this sort of kit.
rockwool or glassfibre insulation makes a fairly good fire break.
Also be 100% clear that once an Arc has formed, it can propagate with less than 3 Amps, what that means is if it is not a dead short , the fuse will not blow and you can sustain something that burns at > 1000 degrees..... so No an Attic is NOT a good place.

50BTC is 'interesting' in a number of respects....... But yes sometimes payouts can take a day or more to be received.. ALSO if you read their site you will see that they do not process payments immediately... But you should get an email...... within 1 minute We would like to announce new payment rules for unregistered users.
Since february 1-st all payments will be made weekly.
This solution will allow us to reduce fees in subsequent users transactions. We have to mentioned that we faced several users complaints:
During transaction operation, which include large number of small fragments user can be charged high fees to pay.
The decrease number of daily transactions will enhance the speed of operations and reduce base growth
Additionally, changes in payment rules will posititvely modify our servers loads, so payments will be proceed faster
So unregistered users will get their money weekly, but not daily. The beginning of the week it is the will be a day when the user is logged.
In case you need daily payments, you can register and withdraw funds manually when it's necessary via regular payments.
They are also subject to some massive DDOS attacks..... But on running a test with my account: payment request 09:42 Email 09:42 Transaction in block chain 09:45 |

Sorry why would you run software on a mac like this?
Far better you VM it and use something that runs on linux, then if you need to scale it... you just upload the VM image to a VPS.
A setup like this is just pissing in the wind......

Worlds first PC with on-board liquid nitrogen generator
 liquid-nitrogen-generator.... http://citizensciencequarterly.com/2011/05/10/liquid-nitrogen-generator/Kudos to them managing to get all that in such a nice case...... But wow...... We’ve taken ASIC processing to the next level with our patent pending ASIC+ Cryonic Architecture™ featuring select low-temperature superconducting materials. hrough a patent pending “scrubbing” process, each FrostBit™ Cryonic unit is designed to filter atmospheric nitrogen gas of dust, moisture, and other impurities. So the thing also shits little pellets of contaminates.... And to stop you 'peeking inside' After assembly, each unit is injected with specially formulated acoustically and thermally insulating foam ensuring cool and quite operation. |

Vapourminer, your pc days you're getting 5+ Gh/s, what's your mining pool say you're getting? And how many BTC's per day are you getting? Thanks!
LOL BTC a day....... work it out Just over $25 a day maybe about 0.2 BTC, the days of getting a full BTC for <10GH/s are long gone...... |

But the controller in the USB-Hubs also count as a "device" some of the bigger ones have two controllers in it.
That is NOT a controller...... It is not capable of initiating a transfer on its own, as such at the most it is a PERIPHERAL DEVICE. And as such it is subtracted from the total count of 127. However for practicable reasons I have yet to see a 'fully loaded' USB system. A guy I used to hang out with did do a full on 127 device chain, back when USB1.1 first came out, and it worked. Bogged the system something fierce, though. With the faster throughput on 2.0 and 3.0, I think it would probably be better. However, it's probably safer and EASIER to just keep the numbers down and use multiple hosts. A usb controller isn't exactly expensive. Even this cheap ass acer I'm using has two of 'em. Ideally you get something like a PCIe card with several controllers (NOT USB ports), then build the chain off that. For SBC's there is a big issue in that you need data-sheets and a circuit diagram to see how it is implemented, I think on the first revisions of the PI it is badly done. One absolute killer is where they use a bloody chip for the Ethernet with extra USB ports on, some of these chips do not even have a TCP/IP buffer!!! so once you get one of these shitty little cutters on your USB chain, you have a chip with multiple Ethernet ports open, with no buffers... sucking the bandwidth out of your USB chain. Even worse are the 'pack of lies' controllers which say USB2.0 compatible, but when you pull the data-sheet they are actually USB1.0 , but they are classed as 'compatible' because the 2.0 infrastructure is capable of communicating with the 1.0 device!!! Only issue is... if you read the USB spec... a USB chain with a 1.0 device on it, defaults the WHOLE chain to 1.0 spec speeds.... (yep they do have some 'hubs' with translators, but it depends on the chipsets used.) It is like a massive Microsoft nightmare, where even accomplishing something a simple as plugging a couple of devices into your computer becomes a major research task. |

In Hong Kong we actually get a "rebate" each quarter against our electricity bill.
So the way I look at it , the government pays me to mine.

You cannot actually "break" a SHA encrypted password, you can only find "collisions" with the hash.
if the hashes match then there is a very good chance your 'key' and the hashed result are the same, but there is not actually any way to find out if it is the actual password OR just a collision.
As regards ASIC's , these have been specifically manufactured to target the SHA256(sha256(x)) algorithm.
Whilst it CONTAINS SHA256, there are usually a number of internal optimizations, that make getting the majority of the work impracticable.
That is to say the ASIC usually only reports a small fractions of the hashes that match a probable solution. The rest are thrown away!!!
So when you see 1GH/s, yes the chip internally produces 1GH/s 'possible' solutions, but in the end it will only externally report from 0-n solutions that match the 'difficulty' it is searching for.
The previous poster is not entirely correct in his assumption of "The primary reason is that no know humanly usable password systems allows for passwords that have the exact binary structure of the Bitcoin block header."
The reality is that the miner chips DO NOT validate the internal structure of the header, in reality they do not give a S**t about what you feed them., they take a source string perform a function on it, then look for a result that meets a particular criteria.
Whilst it is highly improbable a user would have a double SHA256 hashed password matching a given difficulty.. who knows what goes on in the real world!!!
That said, with an FPGA it is possible to make a couple of small modifications to the algorithm and as long as you have the bandwidth to grab the results of each SHA, then in theory you could use the device for password collision detection.

Just seen this in the "multibit" I was running some tests on the block chain and setup a transaction to be traced. I was under the impression that "fees" went into the block chain with the transaction and were collected by whom ever 'mined' solved the block. This looks like a "redirection" of fees by the client?  |

Lol.... 1. It does have a UL marking, just not the one you're looking for. See that cRCus marking in the middle of the bottom? Yep, that's a UL Recognized Component Mark. "These are Marks consumers rarely see because they are specifically used on component parts that are part of a larger product or system." Copied it verbatim from the Ul website but you still don't know what it actually means........ And as a simple Geography lesson.... Repeat after me: "Thailand is NOT Taiwan....." They are not even close, nor do they speak the same language. Thailand: Main industries: Dick sucking, pedophile services, prostitution , cheap electronics Taiwan : Computer design, silicon design , wafer fabs, horticulture. Handy translations: Thailand 泰國 Taiwan 台灣 Simplified Taiwan 台湾 Thailand 泰国 It is you that cannot "keep up" and you have to 'selectively' plagiarize material to attempt to make your point...... Further quotations from the SAME sections of text you selectively plagiarized.... These components may have restrictions on their performance or may be incomplete in construction. Guidelines addressing the suitability of a component when used in an end product are noted in UL's test report as conditions of acceptability. This information can also be found in UL's Online Certifications Directory and the UL iQTM parametric databases. The suitability of the use of a functional safety component in a certain situation or for a particular safety level (SIL, ASIL, PL or Class) must be further evaluated within the context of the end-use application. (Taken from http://www.ul.com) More importantly: The Functional Safety Component Recognition will streamline the functional safety investigation of the final product/system since the component will have already been partially prequalified for the intended use. (Taken from http://www.ul.com) When you have actually modified some E-waste switch mode PSU... please feel free to get back to me, until that time, it is better that you just stick to playing in the sand-pit. |

And this CRAP is from China meant for the China market , manufactured to the same exacting standards as their baby-food. Just because it says 175A on it does not mean it is continuous........ they are dell branded PSUs. it's also shipped from the US. stop spreading FUD. shows how little you know........ 1. No UL marking 2. 'CCC' =http://en.wikipedia.org/wiki/China_Compulsory_Certificate 3. Chinese characters for markings.... Goods sold onto the US market are required to be marked in English...... If you are going to buy 'E-waste' at-least do a bit of research...... |

Ok, but what about RAM memory running out? How do you "fix" that, reboot every 12 hours?
Don't try and run such software on shitty little cutter CPU's, go HERE: http://www.hardkernel.com/renewal_2011/main.phpGet a U2.... 4 CPU & 2GB FAST memory, I've had one on line since Jan......7/24 More importantly the 10/100 & the 'other' USB ports are split out onto SEPARATE USB channels back to the chip, so... no bottle neck. But as with ANY small Flash card based system you really need to watch your write caches. Only had one issue , where I shorted the power and had to pull the SDcard to FSchk it on a 'real' computer. (two if you count the PSU of the shitty china telicom ADSL blowing up..) Just wish they were a bit cheaper...... but they ARE worth the money..... Really am happy with my purchase. |

Split it out as much as possible on separate controllers.
Your throughput will be better.
USB *may* be able to handle 127 devices... but it can only talk to one at a time
By splitting it out to 4 controllers, it can speak to 4 AT A TIME.
If one goes defective then you only loose 25% of your operation... not 100%
Note when I say CONTROLLER I mean HOST controller with a direct distinct & individual data-path back to the CPU.
