Looks like the 5830 info only got half-updated in the original post.

The only reason I suggest some overclock, is that this affects ideal memory speed; ideal memory clock will follow core GPU clock in a non-linear way. ATI cards can typically go from stock 800MHz to 950+MHz given cooling and voltage. The fans are programmed to be quiet to mask their huge power draw, and this let the chips go over 90C. You might look at https://en.bitcoin.it/wiki/Mining_hardware_comparison, ignore the stock speed posts, and take the smallest or second-smallest overclock that a card has rounded to a nice number.

To summarize:
PG: People will send micropayments and donations if they see a vanity address!
DC: No they won't.

This is quite convoluted. The ethical consideration comes down to a simple factor. To make such a decision, we must judge one gender to be less desirable, and that is a statement against all members of that gender; how would you feel about a mother with an unplanned pregnancy who tells you that if the father was white she'd probably have kept it, but because the father was black she's getting an abortion.

It is also viewed as a frivolous abortion; if a mother wants two children, she will be stopping at two; with the gender-selection abortion (when IVF could have achieved the same), she will stop at two desirable children, and abort until she gets there. A genetic disease carrying or malformed embryo who will never have a full or independent life can be selected against by abortion, and this is reasonable to all but the wacky deity fearers; are girls as bad as microcephalic CF kids with their hearts on the outside?

Uh, wot? Firstbits is just another step for users to go through to find out what your address is. It's not a magic trick to get people to send you money; you'd think people would be looking over there ← and sending their pocket change if so. They realize it is just a "send 1000 get well cards to a sick kid" thing, without the sick kid. There are lots of "if you like my post, send me money" sigs on this forum with 0 balances. And here, we all have wallets.

If you have the room and don't need to remember it for later, why not just post the whole address so it can be cut and pasted? The phrases in vanitygen addresses are pretty obvious if you just want to make a cool address.

Double-click on address to highlight it, press CTRL-C. Select the address field in Bitcoin, press CTRL-V. Type in 1 BTC. Press send. Repeat.

Ideally we would get to the point where you can show a QR code to users which includes your address and recommended amount, and on the pervasive Bitcoin mobile phone client, people will snap a picture of it and press send.

Subject has nothing to do with OP...

It's broken, maybe you should contact the site administrator.

Note, that is the keypool of unused keys for future use; any address shown to you in the interface or that has received coins as change is kept when the new encrypted wallet is created, and those private keys may still be floating around on disk sectors and deleted files.

The accounting system exposed by bitcoind is completely whacked. The last time I used it I had several negative account balances and no others added up to anything resembling what was in the addresses. The GUI ignores it for the most part, leaving wild balances, and it should be thrown away and just addresses and labels used.

What should be done here is specify a typically obtainable GPU core overclock that everybody can use for a particular card, then compare who can get the maximum Mhash/s out of that card at that overclock. This will help users discover maximum performance through comparing software setup, rather than becoming that overclock bragging contest. OS/bitness/motherboard/CPU are all largely inconsequential, and only need to be recorded for posterity.

The most important things to accurately note:

• GPU model (+memory size & make, manufacturer part #)
• Driver software version, OpenCL/SDK if not the one included with driver
• Memory clock MHz
• Miner software & version
• miner kernel & version
• miner kernel parameters (worksize, vector size, other settings)

Anonymity is necessary because all transaction can be seen by everyone. Would you use a bank that allows anyone to log on to their web site and see any account by user name and everyone that user has received or sent money to?

The minimum transaction fee is .0005 per KB of transaction message size, if your Bitcoin is suggesting more, it should be updated to something newer than <0.3.23. In addition, you can use sendmany to send payments to multiple recipients at once, which will be cheaper:

This message from the department of propaganda and thought compliance brought to you by VISA/Mastercard. The FBI - we're everywhere you want to be. An Orwellian society with a mandatory bankster tax - priceless.

First post ban!

I would have a 50% chance of finding a case-insensitive "1phinnaeus" address in twelve days on my video card. In that same time I could have mined a guaranteed 2 BTC PPS. Each additional character in length makes it 59 times harder. A case-sensitive "1TurkeyBob" would have a 50% chance in 214 years.

If you want to see if an address prefix was previously used on the Bitcoin network, you can go to http://firstbits.com and type in 1phinnaeus or whatever. It would be possible to do a check yourself on your own website if you have the skills to make a site that integrates Bitcoin blockchain lookups like firstbits or blockexplorer. I mention checking that no other user is simultaneously searching for the same or a similar address on a "generator" web site in my post above, because that is just one obvious way you could mess up and give two users the same private key.

Generating anything beyond a trivially short vanity phrase takes significant time. It would only be practical in a "vanitygen for hire", "check back later and see if we found one" fashion.

Your clients would need to trust you also having the private keys that can be used to spend their bitcoins (dangerous), and you would need a dedicated web server that can run executable non-script binaries on-demand (dangerous), and have security and audited code to ensure that no client can hack the front-end software to get another person's key (dangerous).

The way I would see a "generation" service working would be to have a vanitygen always running, and when a client wants to have a new address searched for, the address they want is validated as workable, has never been used for anyone else, and is added to vanitygen's PrefixList.txt as I used it above only if the list is not too long already, and the vanitygen process is restarted. Software would have to parse the output regularly to find if an address was found and add it to a user's "found addresses" database. All this should not be attempted by someone who even has a hard time running vanitygen, you are liable to f*#k something up by putting such a system online for hackers smarter than you to mess with.

I don't get the problem? If you are trying to build it, build instructions are there, and you can look back in the thread for others' experiences building oclvanitygen. The code doesn't have a comment for every line, further hacking it into something different would need coding skills on parity with the creator.

If you are just trying to use it, here's a Windows binary HOWTO that should have been in the original post:

Installation:

• If GPU acceleration is desired, install ATI Drivers v11.11 or newer for ATI video cards or latest Nvidia driver, test that OpenCL is working with GPU miner software.
• Download and unzip vanitygen-0.17-win.zip to it's own directory.
• To interact with the program, you need to open a terminal/shell/command prompt in the program's directory. In Windows Vista/Win7 Explorer, hold down the shift key on the keyboard while right-clicking the folder where vanitygen was extracted, and choose Open command window here.
• Test CPU operation. This command line will generate a Bitcoin addresses beginning with 1ABCD in around a minute or less:
  >vanitygen 1ABCD
• Test GPU operation. This command line will generate a Bitcoin addresses beginning with 1ABCDE in around a minute, using the first OpenCL device in your system:
  >oclvanitygen -d 0 1ABCDE

Note that a Bitcoin address must start with 1. The default vanitygen operation is to find a matching prefix (start of address), and you must specify the 1 that begins all Bitcoin addresses.

OpenCL GPU device configuration:

OpenCL is the language used for talking to a GPU, and is installed with the video card driver. If the above GPU command didn't run correctly, generating over 1Mkey/s, then you should examine your OpenCL configuration. Remove the -d 0 option ("use device #0") from the command line above and run it again, which will list available OpenCL devices. Here's mine:

>oclvanitygen 1ABCD
Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
  0: [Advanced Micro Devices, Inc.] Juniper
  1: [GenuineIntel] Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz

Both a GPU and the system CPU are available in my system; on yours, the GPU may not be the first listed. "Juniper" is this AMD GPU's code name.

The first line is the platform number, the second two lines are the available devices under that platform. Change the -d 0 line in the example above to the GPU desired. If no GPU is shown, the video card driver or OpenCL is not installed properly. If you have multiple OpenCL SDKs or implementations installed, more than one platform may be shown, specify the correct one (e.g. -p 1 for the second platform if shown.)

Example command lines (oclvanitygen, device 0, default platform):

• Search for exact prefix 1ABCDE, keep searching after first match is found (-k):
  >oclvanitygen -d 0 -k 1ABCDE
• Search for prefix 1ABCDE in any combination of upper or lower case (-i):
  >oclvanitygen -d 0 -i 1ABCDE
• Search for ABCD anywhere in address (only supported on CPU vanitygen) (-r):
  >vanitygen -r ABCD
• Search for prefix 1ABCDE, use a seed file to make address generation more secure and random (-s):
  >oclvanitygen -d 0 -s RandomSeedFile.txt 1ABCDE
• Search for prefix 1ABCDE, keep searching after first match is found, and save all found address to a file:
  >oclvanitygen -d 0 -k -o GeneratedAddresses.txt 1ABCDE
• Search for many prefixes at once using a text file listing them (newline after each prefix including last):
  >oclvanitygen -d 0 -k -f PrefixList.txt
• Use all options above including case-insensitive search, and turn on verbose mode for more information:
  >oclvanitygen -d 0 -v -i -k -f PrefixList.txt -o GeneratedAddresses.txt -s RandomSeedFile.txt

When specifying a case-insensitive address prefix on the command line or in a text file list, you must still only use valid Base58 characters. This means you must only use lower-case i or o, and only upper-case L, or you will get an error.

• Bad: 1celeron, 1CELERON
• Good: 1ceLeron, 1CELERoN

I found an address, now what?

Vanitygen finds an address that matches your search parameters, and provides the private key for that address. The private key is never shown to you in the Bitcoin client; it is used behind the scenes, and is the secret part of your address that you should never give to anyone.

The mainline Bitcoin client does not have the ability to use private keys directly, but you can do other things to use bitcoins sent to your new address:

• Use the "redeem private key" option on MtGox, and input the private key you found. Any Bitcoins sent to the address will now be automatically withdrawn to your MtGox account. This is permanent, there is no option to remove or cancel a private key once it is added to your MtGox account,
• Use an alternate Bitcoin client, such as Armory, that has an "import private key" feature,
• Use the pywallet utility to import your private key and address into your Bitcoin wallet.

The heatsink was likely not mounted correctly on the card that was too hot. If pervasive warranty-voiding anti-tamper stickers were not used, it likely could have been removed and reinstalled with new thermal paste and the problem fixed.

btccharts uses the same format as mtgoxlive.com. The green line is a standard stock price, rotated clockwise by 90 degrees. Rotate your head 90 degrees to see it.

Imagine the other two lines, asks and sells, as an auction with a whole bunch of bidders and sellers, they are making offers on each side, and they meet in the middle. The height is the total value of bids, the further you get from the center trading point, the more total orders there are on the order books.

This kind of chart is primarily used to get sentiment about how deep the market depth is, how many bids and at what price.

Bad data in the database directory will typically not create a runtime error in the Bitcoin exe, you will get a more diagnostic message such as:

EXCEPTION: 11DbException
Db::open: Invalid  ...
...  called after throwing an instance of 'DbException'
what(): Db::open: Invalid  ...

You can rename the whole %APPDATA%\bitcoin directory to something like \bitcoin-backup, and re-run Bitcoin. If you still have the problem, nothing in the database directory was causing it, and likely you need to uninstall and reinstall the Bitcoin software, or fix an underlying hardware problem on your computer.

We send our BTC, wallets, and goods to someone with an anonymous email and no history on the forum? Sounds good!

I will take the first freebie you offer: A class-action lawsuit against john doe, et al., operating mybitcoin, for aggravated theft and wire fraud. I think $3,000,000 might be an appropriate and actionable amount. Feel like doing some filing and subpoenas?
