We can't know if you are entering parameters incorrectly if you don't post what command line statements you are using.

Note that you must go into the abcpool control panel and create a worker (a seperate logon) also, the worker username and password is what you must use as your user/pass for the miner software.

Is Bitcoin in the ALT-TAB list of running programs? Perhaps you can switch to it this way. Also, it's tray icon might be hidden by Windows if you have customized "Notification Area Icons" in the control panel; check the checkbox for "Always show all icons and notifications on the taskbar".

Review the file %APPDATA/Bitcoin/debug.log. It should have any error message near the bottom that will help in diagnosing your problems to see if Bitcoin has really hung or crashed. Bitcoin does take 5-30 seconds to launch though, depending on what it has to do when starting up.

More information about your situation would be helpful in the first post: have you ever had Bitcoin working, etc.

Just to get near a 50% probability of generating a "1" plus nine case-insensitive letters would take about the same GPU processing time as mining 6 BTC...

If you put what you want here with the bounty, perhaps several people could add your phrase to their list of vanity addresses they are already searching for and you might get lucky. You have to trust that the person who gives you the vanity address is also relinquishing and completely deleting the matching private key, or they would also have access to any bitcoins sent to that address.

(case-sensitive)
Prefix difficulty:         888,446,610,538 12345678
Prefix difficulty:         873,388,193,410 1NaNoBit

12345678 is harder due to weirdness about the 0 bits in the underlying unencoded address to make a 2 (in Base58 1 = 0)

For a particular length, case-insensitive difficulty will be lower depending on how many Base58 case substitutions are possible in your phrase, e.g. n has N, but i can't be I; numbers have no substitution.

It appears this is not a concern, that system entropy is still used in addition to the random seed file. We don't get the same addresses every execution:

E:\Bitcoin\vanitygen-0.17-win>vanitygen.exe -v -t 2 -s RandomNumbers 1ABCD
Read 959 bytes from RNG seed file
Prefix difficulty:              4476342 1ABCD
Difficulty: 4476342

...

E:\Bitcoin\vanitygen-0.17-win>vanitygen.exe -v -t 2 -s RandomNumbers 1ABCD
Address: 1ABCDRandomBitcoinAddress

E:\Bitcoin\vanitygen-0.17-win>vanitygen.exe -v -t 2 -s RandomNumbers 1ABCD
Address: 1ABCDRandomBitcoinAddress

E:\Bitcoin\vanitygen-0.17-win>vanitygen.exe -v -t 2 -s RandomNumbers 1ABCD
Address: 1ABCDRandomBitcoinAddress

It looks like we can use vanitygen itself to see how difficult the prefix was:

Case sensitive 1RaTTuS:

E:\Bitcoin\vanitygen-0.17-win>vanitygen.exe -v 1RaTTuS
Prefix difficulty:         888,446,610,538 1RaTTuS

Case insensitive 1firstbit (yes, I had to do it...):

E:\Bitcoin\vanitygen-0.17-win>vanitygen.exe -v -i 1FiRSTBiT
Prefix difficulty:        1,605,983,018,727 1firstbit

note: RaTTuS is harder than most 6 chars  -- case-sensitive prefixes starting with Q-Z or a-z are 59x harder than starting 1-9,A-P):

Prefix difficulty:         873,388,193,410 1Poooooo
Prefix difficulty:       51,529,903,411,245 1Qoooooo

CHALLENGE: post the highest difficulty prefix you've found (use -i if you didn't search case-sensitive.)

addr.dat is a list of recently connected p2p IP addresses, you are giving future clients a bump in connectivity if they already have a list of 1000+ recently seen addresses.

The first board's origin is kind of interesting, it looks like it's a custom board from a company that pissed away $16 million+ in venture capital in three years. Their site is all buzzwords: "Blackwave designed and built the first purpose-built video streaming appliance. Precisely matching intelligent proprietary software with industry standard hardware, Blackwave can drive higher performance while occupying less floor space and requiring less administrative oversight and power consumption." Here's a list of their Management Team archived before the domain expired, so you know who not to hire.

If you had physical access to the machine, then the owner of the machine cannot be confident of anything.

It sounds like what you want to do is to take a currently running bitcoin's %appdata%/bitcoin directory (without the wallet.dat file) and copy it to the new pc to the user's default location. Then install, but do not run, Bitcoin. This means that the wallet.dat and addresses are not created by you, but the blockchain/IP addresses are there for a quick startup.

PS, use Kubuntu, nobody likes GNOME.

Trading on volatility is all fine and good, until the market leaves you behind.



In July, 14 might have been a good place to play volatility, until you bought at 13.5 with it never to return. In September, 5 could have been the new 14, until you bought in at 4.5 with the price never to return. At a certain point you have to "margin call" yourself and take a loss on a downturn to get liquid again if you still want a tenth of a point every day. Most people don't mind a position of being all-in dollars, but being all-in BTC (or any foreign currency market) doesn't help pay the rent.

If you meet someone in person, they won't need to know who you are, hand them the cash and give them your Bitcoin address.

An answer I posted in a noob thread, what I gathered from the Wiki, how many confirmations required before resending coins is TX-fee-free:

Transactions need to have a priority above 57,600,000 to avoid the enforced fee in the official client. Transaction priority is calculated as a value-weighted sum of input age, divided by transaction size in bytes:

priority = sum(input_value_in_base_units * confirmations)/size_in_bytes

For sending 0.05 BTC (5,000,000 base units) from one address, in 225 bytes (a minimal size, a one input, one output transaction with no remainder)

free when confirmations > 57,600,000 * 225 / 5,000,000 -- 2,592 confirmations

Having Bitcoins from multiple payments fund the transaction is where the "sum" in the formula above comes into play.

A more informative dialog in the Bitcoin client could be "This transfer requires a minimum .0005 bitcoin fee due to recently receiving the source funds, and the size of the transaction in bytes. This transfer would be free after xxx more confirmations (approximately xx days)"

ATI 11.10 WHQL - Now works! It appears that the newest SDK is the fix, as by extracting the ATI "driver only" downloads, you can install just the video driver you want, and then install the newest 2.5 SDK from C:\ATI\Support\11-10_vista32_win7_32_dd\Packages\Apps\OpenCL. I have tested this SDK with the 11.6 and the 11.10 video driver.

Memory speed seems important to keygen speed too. If you've downclocked memory for mining, be sure to bump memory speed back up to default or even overclock.

Benchmarks:
CPU: 113 Kkey/s per core on 2.4GHz Intel Core2 Quad (32 bit)
CPU: 131 Kkey/s per core on 2.7GHz AMD Sempron 140 / Athlon 64 X2 Kuma
GPU: 15.3 Mkey/s on ATI Radeon HD 5770 (1000/1300)
GPU: 20.5 Mkey/s on ATI Radeon HD 5830 (1050/1050) (5 char address in ~13 seconds)

Greece's debt problem is that they can't print Euros like they printed their own currency into hyperinflation (re-denominated three times in 50 years). Actually paying off debt without being able to just print the currency into valuelessness must be quite the paradigm shift for them.

Greece 100 BILLION drachma note:

Whatever is in the front of the goodwill bin?

I would be more curious how the poster plans to ship them. Typical shippers use this box, and pack similarly to these instructions. Sending 15 oz priority mail is more than 2 BTC.

A wallet is one of the files that contains your address and private keys, and is generated on your computer when you run the client software. I think you mean you want to download the client software?

(also applies to noob's post here)

You should be familiar with Bitcoin and how it works before you waste your time with the "alternate" currency forks that people have created.

I get a similar hang on 1.6.4 pretty quickly mining on mineco (win32 exe and .py), WinXP and Win7, 5770 and 5830:

Cooling the back of the PCB through thick pads seems dubious, especially when still using the stock cooler too. The thermal resistance between the components that actually generate heat and the water block is too high which would create a big temperature delta. If you have 25 degree water, you'd probably have a 35 degree copper plate, 45 degrees after the thermal pads, a 55 degree PCB, and 75 degree components still.

What you would want to do is get a real engineered water block for each of the GPU chips to replace the stock cooler. The GPU die is where 85% of the heat comes from. Inside real water blocks, it looks like a mini-radiator with fins or pins for excellent heat transfer characteristics directly from the die to the coolant:



For a cheaper and better radiator, you can get a wrecking yard transmission cooler or oil cooler, it will transfer heat and return the water to ambient temperature much better than copper pipe, and unlike using a car radiator, you don't have a radiator cap & bottle outlet to leak or need big hoses:


Of course none of this is necessary, people here have multiple GPUs per system in multiple systems running on air and stock coolers.

No it is not good to invent hardware and yours.

Charity is good though. I have dislexia since before birth which makes writing hard very easy. So if you don't want to help with bitcoin I sent you an email.

You could post it on /b/ and wait for the fun.
