Very cool. How about a micro u symbol (easy to type on Mac)?
You mean you want to type "μ", a lower-case Greek letter "Μ"? There's already a keyboard layout for that.  If you want to add that single character, or even add the whole Greek keyboard when you press ctrl or alt, you can do that with the keyboard creator yourself. |

http://bitcoin.org/bitcoin.pdfSection 4; Section 11 The actual "strength" of the blockchain is the chain of difficulty targets stored in blocks since the time of the block one would attempt to replace. The SHA256 hashes of blocks are all below the target; finding such a hash is computationally expensive. By definition, other miners would reject a sequence of blocks where the difficulty target is not as expected for the difficulty period of 2016 blocks or the block hashes did not meet the difficulty. In the actual block, "bits" is a compact form of of the target. {

In the reference Bitcoin client, all change activity is hidden from you. It works without confusing anybody. It is only the availability of other tools, which reveal what is happening behind the scenes, that may confound.
Change is required for you to be able to send arbitrary amounts, since only a complete input (previous payment you received) can be spent.
It is not desirable to have your Bitcoin balance easily determined by any user worldwide, much as you wouldn't want anybody to be able to see how much is in your real wallet or your bank account. While Bitcoin doesn't promise anonymity, it does what it can to complicate remote payment observations, given that the blockchain of all transactions is public:
- A user can have a near infinite number of addresses, all centrally managed by the software,
- An address can be used once and never again (Bitcoin does this for change, and leaves it up to the user to do this with all other payments),
- When there is a payment and change sent, Bitcoin makes it harder to determine which is the actual payment.
The opposite extreme would be one single address per user, where anybody you transact with or share your address with would be able to see your bank balance and determine everybody you've been doing business with and how much you've been paying them. Few users would desire this behavior.

Love it. On the back I might want something like:
BTC an idea too big to fail.
That is a phrase associated with bailing out banks and has a negative connotation. |

It tells me to check whether the file is still there and accessable, then try again to install,... its still there and accessable, but the set up wont continue.
I downloaded both (64 bit and 32 bit) versions, none works. The 32 bit version is not for me and the 64 bit version displays above mentioned error.
I fixed the download link file (re-created the keyboard layout actually), you'll need to unzip and run setup.exe, which will install on any windows platform. |

Inspired by the above post from the thread entitled What is Bitcoin? (In 21 words), I offer up the following challenge. I will pay BTC1 to the person whom best my 14 word submission on a Tee depicted in the image below the rules. - Must contain 14 words or less, explaining Bitcoin to the masses in a concise way.
- Must be grammatically correct.
- Must be written in E-Prime.
- Must be presented as an image of a Tee (or similar) with the wording legible (no funky font).
- The use of a Bitcoin symbol is preferred but not mandatory.
- Based on at least 10 different members submitting at least one design (multiple submissions allowed).
- Feel free to even improve upon my submission.
- Time frame will be 7 days.
- Judging will be solely by me, but will give considerable weight to comments on quality submissions.
Hopefully, there'll be no need to modify the rules above, but I reserve the right to amend them. Fear not, for I've proven to be über fair. ~Bruno K~  |

The transaction was relayed - that is how blockchain.info knows about it - it was broadcast around the network. However, as it didn't include the minimum 0.0001 per KB fee for relay through the p2p network, only those that have a direct IP connection to Satoshidice's server or another peer that has relaxed relaying policies would know about it, and the chance that there is a miner with this transaction waiting in their memory pool is low.
Bitcoins don't magically end up back in the wallet if they are not included in a block. The Bitcoin wallet software considers spent coins as spent, and it takes manually removing the transaction through wallet editing tools to restore the balance shown in the wallet - likely SatoshiDice is not going to do this for 0.001 BTC that they consider "sent" (and should have just kept/ignored) so the coins will probably be considered lost.
As a followup, this transaction was included in Block 216642 by Eclipse mining pool after 10 hours, along with several other transactions that did not pay minimum fees. |

Someone with the knowledge (and desire) to compute the probability could say how often that occurs. It isn't that rare, ... maybe occurring once a week (wild-assed guess).
Maybe someone could have already said... (or someone could search before starting a thread.): So the chance a block won't be found after 10, 20 minutes, etc. (and the 1 in x chance) >>> for x in range(10,131,10) :
print x, '%2.5f%%' % (100*math.exp(-x/10)), '%1.2f' % (math.exp(x/10))
20 13.53353% 7.39
30 4.97871% 20.09
40 1.83156% 54.60
50 0.67379% 148.41
60 0.24788% 403.43
70 0.09119% 1096.63
80 0.03355% 2980.96
90 0.01234% 8103.08
100 0.00454% 22026.47
110 0.00167% 59874.14
120 0.00061% 162754.79
130 0.00023% 442413.39And every day we can reasonably expect a block longer than 49 minutes, every week one longer than 69 minutes, every month 83 minutes: >>> for x in [ 10*math.log(144), 10*math.log(144*7), 10*math.log(144*365.25/12)]:
print x, '%2.5f%%' % (100*math.exp(-x/10)), '%1.2f' % (math.exp(x/10))
69.1572344863 0.09921% 1008.00
83.8548870042 0.02282% 4383.00So if hashrate maintains at a level as predicted by difficulty, you would expect a >60 minute block every three days (red), however if hashrate drops to 83% of the predicted rate, a >60 min block averaging one a day would not be unusual (orange) (don't forget, many long blocks one day and none for many days in a row also would not be unusual, variance tells us the unlikely is just as likely). You can get a rough idea if the hashrate may be decreasing here: http://dot-bit.org/tools/nextDifficulty.phpIt has both difficulty predictions for Bitcoin and Namecoin based on several periods. As Namecoin is also mainly merge-mined by Bitcoin miners, it can be a secondary indicator to evaluate the true direction of hashrate (as block finding, even over many blocks, is random, and can be non-predictive of actual hashrate). In addition, I just asked myself "Does it matter if it's the weekend or not?". Well, here's the number of blocks found by day of the week for Jan 16 2012 (Monday) to Jan 13 2013 (Sunday); it's hard to assign any significance to any day:  |

You would be better off getting a $50 three-year-old ATI 5770 and plugging it into a second PCIe slot for >200MHash/s at 1/4 the wattage. Any video card decision that has Bitcoin mining as any part of the purchase criteria immediately rules out nVidia.

I googled for you: http://www.warriorforum.com/main-internet-marketing-discussion-forum/267429-accepting-payment-via-bank-transfer.htmlYes, wire transfers are as reversible as anything else. Any movie that shows the spy with the laptop wiring funds for the super-secret microchip is building on a completely false premise. Anything banking is all on a web of trust, and if the originating bank wants their money back they will get it back. In addition, for this "service", banks often route the wire transfer through several other banks that are part of their network of good ol' boys that take a cut of the transfer - you can have $50 or more taken out of your money transfer from mystery banks along the way. No banking payments should be be trusted at face value; consider every payment as trustworthy as if it was sent from foreign hackers who have compromised online banking accounts and are looking to liquidate stolen funds, unless the payer can prove otherwise. |

I was there when MtGox got hacked, and when bitcoins where selling from $30 to $32, but that was over a year ago.
Well over a year ago... Here's 18 months, today's exchange rate hasn't been seen in that long.  There was only one big (real) market crash, in May-June 2011, mainly fueled by the MtGox hack and magical disappearance (and selloff of stolen funds?) of mybitcoin. |

If you want to be anonymous, then there are two aspects to consider, IP address leakage, and address tracking. Both are a concern only when they reveal payments that can be tracked to you, since Bitcoin itself isn't illegal anywhere (although your use of Bitcoin could build a case: "We intercepted drugs mailed to him, and we know his IP address runs Bitcoin, a nefarious underworld currency only used for buying drugs".) You can install the software, and synchronize the blockchain without revealing any information about yourself, except that other Bitcoin users may be able to detect that you are also running Bitcoin at your IP address. There is one exception to this statement, a recent disclosure documented a potential issue where an attacker might be able to discover if a particular address is owned by a particular peer. When you receive money, no information is communicated with your client specifically, the payment is just recorded in the blockchain, a payment that only you can spend. When you send a payment from your own client, however, the transaction is broadcast on the p2p network to all other clients to which you are directly connected. There is a relatively high chance that another well-connected Bitcoin client can determine the IP address that initially broadcast the transaction if mitigation is not done (such as limiting your Bitcoin to only one edge-of-network peer connection to send your payment.) If you are in a hostile regime where all Internet activity is recorded (perhaps the USA, although the drone strike from above would be the only indication that your funding of terrorism was detected) then TOR with a foreign exit node and a state that doesn't have the resources to get a majority of TOR nodes to corroborate ins and outs would be necessary to anonymize your connection and payments. The second issue is your conversion of goods and currency to Bitcoin, the trail of addresses is usually easier to follow than IP connections, if specific anonymizing steps are not taken. If I buy or sell something from you, I might send you a payment that is later mixed or connected with other payments you have made or received. |

It isn't a problem with Bitcoin, it is your security software not remembering the per-program firewall access settings that you have designated.
I solve these problems by removing the firewall software.

this coins aren't mine, it was just an example.
what how exactly the coins will return to satoshidice?
Transactions that are never relayed and/or never confirmed eventually end up back in the sender's wallet... as if the transaction never happened. This usually takes a day (or two). The transaction was relayed - that is how blockchain.info knows about it - it was broadcast around the network. However, as it didn't include the minimum 0.0001 per KB fee for relay through the p2p network, only those that have a direct IP connection to Satoshidice's server or another peer that has relaxed relaying policies would know about it, and the chance that there is a miner with this transaction waiting in their memory pool is low. Bitcoins don't magically end up back in the wallet if they are not included in a block. The Bitcoin wallet software considers spent coins as spent, and it takes manually removing the transaction through wallet editing tools to restore the balance shown in the wallet - likely SatoshiDice is not going to do this for 0.001 BTC that they consider "sent" (and should have just kept/ignored) so the coins will probably be considered lost. |

The more that people think Bitcoin will go up, the less likely they are to sell now, and the price goes up.
A computer with $1000 of video cards brings in just a trickle of Bitcoins now.
