Unfortunately, a lot of the world's commerce is still tied to the dollar, and the most liquid BTC exchange is USD-based. I use the following script to retrieve recent trades from MtGox.com and calculate a volume-weighted average over the last 48 hours. This gives an exchange rate of BTC<->USD which is reasonably steady and is based on the most liquid (currently) BTC exchange. You could modify the script to pull in the current USD<->EUR rate and then use it as a basis for setting prices. #!/usr/bin/env ruby
require 'open-uri'
require 'json'
total_vol = 0.0
price_vol_product = 0.0
quote_str = open('http://mtgox.com/code/data/getTrades.php').read
quotes = JSON.parse(quote_str)
#puts quotes
quotes.each do |q|
price_vol_product += q["price"] * q["amount"]
total_vol += q["amount"]
end
usd_per_btc = price_vol_product/total_vol
puts "Exchange rate: " + usd_per_btc.to_s
[edit] Oh, and please do consider setting up an exchange in your area! The more the better. There are a number of directories of exchangers: https://en.bitcoin.it/wiki/Category:Exchangeshttp://bitcoincambio.com/exchangershttp://tradebitcoin.com/You can either use one of them or list yourself if you set up your own. |

Ok, yeah, it works. I don't like messing with the hosts file because I've forgotten in the past that I made changes to it and then couldn't figure out why I couldn't reach a site by name because it moved.

Do you offer Rails 3 and Ruby 1.9? It seems that there some compatibility problems between Rails 3 and cpanel.

One day left on this auction. At the current difficulty, it should net a block every 14 days, 13 hours. Or, earn a steady ~3 BTC per day in a pool.

The new server appears to be fully functional. You just need to add the new IP 174.121.74.59 to your hosts file until your favorite DNS provider refreshes.
All I get is a page that says "No data here" when I go to that address. |

They don't seem to be aware of BitCoin. Otherwise they would have mentioned it at the start. The key difference is they focus on the offline case whereas Satoshi really does not.
The paper is from 2005. I wonder if Satoshi knew about it? |

Splendid rework of the site! I know Bitcoin is in good hands when I see stuff like this. Donation sent.

How did all of those 0.0001 fees get into the transactions? |

What specs do you need? Voltage, step angle, motor size, shaft size, unipolar, bipolar, etc.

I've seen that link plenty of times, but if you're going to go to all that time and expense, why not just buy another case, mobo, PSU, etc? The more time you spend fiddling around trying to get something custom working, the further up the difficulty will climb. I've got plenty of ideas myself what could be done better or differently to build a mining rig, but I'm not going to bother at this point in time because the ever-increasing difficulty makes it pointless. |

I plan to keep my miners running until they fail. I don't think it makes any sense to invest in additional equipment, however. It will be interesting to see how the fees evolve. I've received as much as 0.05 per block lately.
There will always be plenty of gamers willing to absorb the surplus GPUs.

I wouldn't say it's pointless, but you need to have a lot of patience if you are going to solo mine with only a single GPU. I think most people would willingly pay the 2-3% to see a steady stream from a pool.

I don't know slush's exact arrangements, but I can see from the IP address that he's hosted in Linode's London facility, so I wouldn't be worried on that front, Linode's infrastructure is good. I think this has been almost entirely a matter of raw resources.
|

So really I am only at a loss of 1/3 of one percent as a result of this problem which, as I've said before, may be on my end or somewhere between me and Slush's server ( in the Czech republic).
I thought Slush's server was in the UK. |

The main problem is cooling, not slot availability. You need an empty slot next to each GPU so the fan can draw in cool air, unless you implement some sort of custom cooling solution. That means each GPU effectively needs three slots, and ATX only gives you 7 total. If those PCIe risers were tall enough and had holes in them...that might help.

I just tested it out for you. Here's the command line syntax for using puddinpop's miner with deepbit.net: C:\puddinpop>rpcminer-cpu -url=deepbit.net:8332 -user=email@domain.com -password=xxxxxxxx Of course, substitute your own email and password. Now excuse me while I reboot back into Linux...  |

In order to use your GPU for mining, it must be supported by OpenCL or CUDA, and I don't believe yours is supported by either. Your only option would be using the CPU. Give puddinpop's RPC miner a try (there's a thread in this section). It should work fine with deepbit.net.
