But sometimes I just need the distraction. I'm a computer programmer, and when I'm thinking to long for something and it's just not working I don't get anything furter. The I read one or two news articles or some new posts on this forum, then go back to work and suddenly just see the problem I was having. Perhaps it's not that way for everybody, but for me it is better that way. Ofcourse hours and hours checking facebook and funny cat sites is bad  |

Ok I think this has gone overboard. I'm willing to bet that everyone in this thread has "stolen" company resources. Ever gone to the bathroom outside your allotted break? That's theft of time. Used a company phone to make a personal phone call? Theft of time. Talk to your coworkers about the NCAA tournament? Read Facebook at work when it's not your job to do so? Used a sticky note to jot down something that you forgot about to do at home?
etc, etc.
My 7970 (at home) costs me $0.64 cents per day to mine. The shit I just took at work 10 minutes ago? $2.08 of company time.
Listen, I get that you don't want bitcoin to get a bad name, and these actions would darken bitcoin's image. But seriously, I would have just ignored the kid, not get him fired. That's wrong, IMO.
Well, bathroom is obvious, I just can't hold it 8 hours. The rest, if the boss don't allow this small things the morale would get lower and actually less work will be done. The use of cpu's for mining for bitcoin doesn't do a thing with morale and just steal electricity. /edit, not sure if morale is the correct word for this (primary language is not english) Maybe working atmosphere is a better one. |

I still think the most important thing is that they have not figured out how to circumvent the proof of work... they will eventually include transactions when you can make some btc's from it.. currently it is still mostly block reward!
Why do we know that? We know that they solve about 30 blocks/day. For all we know they might have found a semi-analytical/statistical algorithm that just takes a few computers and we calculate their hashing power only by solved blocks. AFAIK there's no conclusive evidence that it takes them 1.4GH/s to solve 30 blocks a day. That's just based on the current difficulty. All we know is that it still takes them at least some work to do it, otherwise they would be faster by now. That simple can not be true because I want to be the first who finds a flaw in (double) sha256 and make bitcoins that way. btw, I'm sure there is a way to find collisions or even create a specific hash value, I'm just not sure if it will be found before 2^256 is possible to bruteforce. |

Good to hear that  I'm from the Netherlands, so I don't really know how things work in the USA. |

The butterfly labs website mentions 'Hot plug clusterable' for the single, but nothing like that for the rig box, so I don't think so.

Still waiting for someone in the EU / UK to let us know what the total cost was including duty and all that crap ( VAT ) etc.
Any news about a EU distributor or something like that to avoid all these silly taxes ?
Thanks !
I could do that, problem is i need to charge some profit. Also i need to charge VAT 23% when selling to EU resident. So the price would end up being something like 850$  Yeah not sure where people get the idea that a distributor makes the VAT go away. AFAIK (and granted euro tax law wasn't may major in college) BFL -> Customer (pay VAT) BFL -> Distributor (no VAT) .... Distributor -> Customer (pay VAT) right? I think it's a problem when this happens : BFL (add VAT to the price) -> customs (add EU VAT to the price) -> customer (WTF!? 2 times VAT?!) It is possible to get a refund done for some part of the VAT, but I have no idea how exactly it must be done. Some stupid paperwork. |

Something like http://www.1-core.com/library/digital/fpga-logic-cells/ ? You can see there is a difference between diffirent Xilinx families and even bigger differences between the manafacturers. On the bottom, The architectures are very different, so it's difficult to compare them objectively. It should be understood that the results of such comparison have limited application.
It is usually the number of LUTs (and not the number of registers) that is a bottleneck for FPGA designs. From this perspective, it could be stated that one Virtex-5 slice can in theory substitute 8 Virtex-4 slices or 4 ALM's. But in real-world designs it is impossible to utilize all the resources. For differences between chips of the same family you can look at the manufacturer site. For example : http://www.xilinx.com/publications/prod_mktg/Spartan6_Product_Table.pdf |

It may be profitable as a CPU miner on Litecoin especially if the LTC price rises a bit?
lol I think there's a better chance of Satoshi Nakamoto trying out for American Idol (and winning) Yeah but it may turn out as the most profitable LTC CPU miner for (kH/s)/W and if the price rises then it could become actually profitable? Or if your just mining LTC for fun/speculation it maybe the cheapest and most efficient pieces of hardware for the job. At £30 and 5W(I think) then it's a cheap hobby/speculation. Is litecoin profitable somewhere in the world? Yesterday I did some tests and calculations for my Q6600 (intel quad core@2400MHz), if my calculations are right I use 1 euro/day electricity and when I change the litecoin for bitcoin and sell them I get 0.01 euro/day back. If the raspberry pi would get the same hash/sec (I doubt it) and work with 0.2Watt I would break even. |

I remember that too, I was in the second grade - The Beastie Boys - Find for your right to party / I felt like the coolest kid in the world at that moment but im talking about that wow factor, cds did not even have the wow factor like when MP3 was introduced (Except when i got my first cd-rom drive - that was REALLY cool), not for guys like us that been around for awhile, im sure the guys who are here in there early 20s dont even care cause they grew up with them Nice, I was reading that like, "The Beastie Boys - Find for your right to paaaaaaaaaaaaaaaaaaaaarty!!!" |

Nice to see some data. Soo.. the bitcoin hash rate would be in between 64 and 128 some where?
Bitcoin is a a 512 byte block which is double hashed. That means ~3 million hashes per second or 1.5 MH/s (bitcoin double hashes). Obviously that code is not optimized. Maybe optimized code does 2x better say in 3 MH/s ballpark. Mining with GPU & CPU combined is likely still under 5 MH/s. Seems foolish to use it as a miner if it is controlling GH/s worth of FPGAs. It locks up and GH/s of FPGA boards go idle?Bitcoin is a 80 byte block. 4 bytes version 32 bytes previous hash 32 bytes transactions hash 4 bytes timestamp 4 bytes nounce 4 bytes difficulty (last 3 times 4 bytes might be in different order, can't remember right now) After padding the block is 128 bytes. The first 64 bytes of the block is the same during a work unit so that part in only hashed once. The second part of 64 bytes is hashed many times with each time a different nounce. Each 32 bytes output is padded again to a 64 bytes block to be hashed again. So the effective hashing rate would be around 1629.47k / 2 = 814.735k according to the OpenSSL test. |

Weston EU almost certainly has so called half-hourly power meters and have ability to chart their power usage in almost real time. Even if he stopped CPU mining (allegedly), abnormal power usage particularly during night hours in recent past would be obvious.
There is only one commodity on this planet that is indeed infinite...
Is stupidity called a commodity? |

I you put this at kickstarter or sell it or what ever, how much do you want for it?
Is it around $500 or more around $2500 or even $50,000 ?
How many hours did you spend roughly?

 Bare board in my hand for size comparison. Click on it and zoom in to see an interesting thing - a header marked "LCD".... I need to go for now, haven't gotten it started mining. I'll be back later to post more. The atmel chip is also interesting. I can't completely read the chip number, but it looks a lot like http://www.atmel.com/devices/at32uc3a0512.aspxA 66 MHz 32bits AVR microcontroller. Most other boards just have the communication done in the fpga itself I think? |

The transactions are currently not worth beeing included and that needs to change.
When the block value drops from 50 to 25 BTC the transaction are a bigger part of the mining, so that's already going to change. |

No economic benefit? They are being subsidized by the community for 50BTC per block for Christ's sake. IMO no tx no subsidy,
Just reject the empty blocks and if there are no transactions there is also no use for additional blocks.
They are being subsidized by a magic money-making algorithm, not the community. The mining reward is well thought out as a way of releasing the currency and encouraging blockchain difficulty. The only thing encouraging the inclusion of transactions in the generated block are transaction fees, which recently are approaching zero.Interesting block. Would it be possible the owner of the 1VayNert... address is the mining pool that did a large payout to multiple addresses and didn't broadcast these transactions over the network but generated this block? It would be an interesting idea for mining pools not to pay transaction fees if they can create blocks themselves for confirming the transactions. |

Rejecting empty blocks would be a bad idea.
If a block is generated with all the transactions so there are no more unconfirmed transactions, all hashing would stop until someone makes a new transaction.
About the botnet idea, why only one 'exit-node' to submit the work to the bitcoin network?
If I would make such a botnet, I would create multiple smaller networks within the big network so I wouldn't have to host them and they won't get to much load.

Yes.
If the field has 10 mines and 15 free fields you have a chance of 15/25 to win x1.54 so on average you get 15/25 x 1.54 = 0,924 BTC for 1 BTC.
