A transaction sending 0.4 BTC with 100 confirmations is not high enough priority to send with no fee.
priority = sum(input_value_in_base_units * input_age)/size_in_bytes
((0.4 * 100,000,000) * 100) / 258 = 15,503,875
Transactions need to have a priority above 57,600,000 to avoid the enforced limit. I would recommend ANY payment include a fee even if it would qualify to be free, as "free transaction" space in blocks is limited, and profit-motivated miners have no incentive to include free transactions over those with fees.

Bitcoin has a proof-of-work system, so does the forum! Besides reducing robo-spam, it also gives you some time to search and read before posting a question (or theory about why Bitcoin will never work) that has been previously answered multiple times.

This is now a noob thread for torrent talk, new versions of Bitcoin have a different database format than previously posted, and importing the bootstrap torrent is safer than using an already-compiled block database from someone else.

Turn off computer, pull hard drive, do not use it if you want any chance of recovering data.You will want to perform offline full hard drive scan for private keys, which will take many hours: https://bitcointalk.org/index.php?topic=38004.0

If I recall (the site is down for now), the deposit addresses are one time use only within 24 hours, they are not for recurring payments. I have never tested what the website says by not following the instructions.
You could contact the admin and see if the payment has been received to their wallet and uncredited, but there is also no way of verifying that they are your namecoins if any database record associating them to you is gone.

Wow, that must have been a 1000BTC market sell.
Love the wall at $135, too.
That's not a wall, that's a sell-off five minutes too late. Got left behind on the way down to 126. |

Just someone selling 2000 BTC / profit-taking a quarter of a million in $.

Well something's happening, lag just jumped from 45 seconds to five seven minutes - in 45 seconds. It's going in some direction soon to be revealed.

If you have your bitcoins on an exchange instead of your wallet, you can sell them instantly. You don't even need to do anything, you can just put in a book offer to sell them for $140, for example, and if the price increases to that they will be sold. (edit, fixed example amounts)

The function you are looking for is valid private key -> ECDSA secp256k1 -> public key You must also have Bitcoin's base58 encoding/decoding if you want to use or import the "5J" style private key. Javascript: Look at bitaddress.org source code. It's very easy to read. Near the end there is the wallet details tab. You'll see there which functions are called to get the public key. Search back for the function and see how it's done. This code is also good as a template for writing in other languages. eg. some bits chopped out, var ecparams = EllipticCurve.getSECCurveByName("secp256k1");
ECKey.prototype.getPub = function () {
if (this.pub) return this.pub;
return this.pub = ecparams.getG().multiply(this.priv).getEncoded(0);
};
ECKey.prototype.getPubKeyHex = function () {
if (this.pubKeyHex) return this.pubKeyHex;
return this.pubKeyHex = Crypto.util.bytesToHex(this.getPub()).toString().toUpperCase();
};A bit more digging and should have it. References: Math: http://cs.ucsb.edu/~koc/ccs130h/notes/ecdsa.pdfcrypto++: http://www.cryptopp.com/wiki/Elliptic_Curve_Digital_Signature_Algorithm#Public_Keyopenssl: http://www.ruby-forum.com/topic/4407216 |

Namecoins also are now trading at .008 BTC, or ~$0.80, which is a 100% price spike above the previous months, and certainly higher in government currency than they have ever been. Alternate currencies may be seen by some investors as having more upward potential than already-recognized Bitcoin.

http://we.lovebitco.in/mining/You will not find the same hash as anyone else, different miners will have different information in their blocks, including the address the reward gets paid to. The only competition is if miners simultaneously find a block solution for the same block number - the miner who can communicate it to other mining nodes the fastest will likely win. Unless you have a room full of equipment, you will likely join a mining pool, which will give you regular small rewards based on your work, removing most of the variance. With a average consumer video card (like a HD 5770, 200MHash/s) solo mining is an extreme example of a lottery: | Probability | Time | | Average | 1664 days | | 50% | 1153 days | | 95% | 4985 days |
There's a 1-in-20 chance that your first block won't be found for 13 years, and that's if the network difficulty never goes up (we know it will double or quadruple in the next year just based on ASIC orders). You could also get lucky and mine a 25 BTC block sooner than the several years it would take to earn 25 BTC from a pool.

Tor exit node IP addresses are easily retrievable from the network. http://torstatus.blutmagie.de/If your IP address is on the list because you or your dynamic IP address has been an exit node, this is likely why you were identified as such, even if you weren't using it to connect. |

A bereft man asked his clergyman, "Pastor, my beloved dog recently died. Could there be a service for the poor creature?"
The Pastor replied, “No, we can’t have services for an animal in this church."
"But there is a new church down the road, surely they will do something for the sweet animal...for a donation of 100 bitcoins..."
The Pastor ejaculated, "Sweet Jesus! Why didn't you tell me the dog was a Christian??"

How about accepting Credit Cards? Does that not hold the same inherent fault.
My question is: Can a credit card transaction be reversed the same way that a PayPal transaction can?
Yes, of course. You only need to call the credit card company and dispute the charge, even simply saying that you were unsatisfied with the purchase. The business is charged a $25 in addition to having their money taken back, has to file paperwork if they want to dispute the chargeback, and too many chargebacks and the credit card company may "review" the merchant agreement. Credit cards also have the flaw that in order to use them, you must provide an internet site the exact information needed to also create fraudulent purchases. If someone merely copies a 16-digit CC number, they can impersonate the owner and create bogus PayPal payments. Hacks and data leaks of corporate web sites typically involve thousands of credit card numbers and owner details, and criminals gangs in lawless countries look for ways to turn this information into money. |

So, those are public addresses I can give out, right?
But I hear a lot about how a wallet has both private and public keys, where the private keys are what send money.
Can someone please clarify this? ;-;
Bitcoin addresses use asymetric Public-key cryptography. For each address you create, there is a secret matching part that is stored in your wallet, but is never shown to you. The secret key is used for digitally signing messages transferring your bitcoins to someone else when you want to send a payment, to prove that you authorized the transfer. This is merely an interesting fact. To receive a payment, just give someone your address. To send a payment, just put in their address and the amount to send, and press "send coins". |

The reference Bitcoin client includes a minimum fee when required and would not take that long, so we assume you are using something else that would cause such delays. In Bitcoin's options, an optional fee can be added that will give your transaction further preferential treatment.
If you are using a web wallet or other service, you should contact the operator or their forum thread and ask why they aren't including the minimum fee required for normal processing.
