Weird, I just lost 36 in a row playing the 50% address.
I call bull-puckey, address or it didn't happen. Here's the only people betting many on 50% in the last hour:

i never got any and look how far back i posted i think this is a dry run guys 

Edit: I'm done watching this thread for now, so I'll leave it for anybody else that wants to offer free money!

(note for requesters: don't make this a begging thread, look thru the thread and see if someone else is giving away their money)

Maybe look at the original date of the thread too.

Try -salvagewallet first.

The usefulness of your backup depends on your keypoolsize (default: 100) and how many keys you've used since the backup.  Every time you ask for a new address, you use one key from the pool.  Every time you send and get change, you use one key from the pool.  If your wallet isn't busy, a backup from a few months ago may still be fine.  Try -salvagewallet first anyway.

The "not enough space" message probably doesn't mean what you think it means.  Check your db.log file for clues.

hmm, I've always put 'keys=0' in my config file, to stop wallet bloat
This is a very bad idea. When you send a payment, the remainder of an input is sent back to you to a new address. Normally this is sent to one of 100 reserve pool addresses that are pre-created. If you make a backup of your wallet with no reserve keys, as soon as you start spending money, you will be receiving change back at addresses not in your backup, making your backup instantly obsolete, and guaranteeing the loss of funds if you need to use the backup.

Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing (platform)
  0: [Advanced Micro Devices, Inc.] Cypress (device)
  1: [AuthenticAMD] AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ (device)

oclvanitygen -i -k -d 0 -o bond.txt 1jamesbond
You need to specify the correct platform and device. In your case it would be -p 0 (AMD OpenCL), -d 0 (Radeon HD 5830).

You also need a compatible driver/OpenCL. I would recommend Catalyst 11.11.

- I see a useless post mentioning BFL,
- I press report to moderator
- That subforum's moderator deletes the crap
- Piss of a moderator too much with off-topic replies, and you are toast.

Now this goes for whole off-subforum-topic threads too.

However, out-and-out trolling in that particular thread was tolerated far too long.
1709  Bitcoin / Bitcoin Technical Support / Re: Bitcoin crashes after downloading the blockchain on: January 24, 2013, 02:38:00 PM
I suspect that your computer is crashing because of a hardware problem. Lemme guess which one:

1. Overclocking CPU
2. Laptop

Bitcoin does not have any error message relating to disk space; when it runs out of space to download the blockchain it just crashes. Such an error would be from the operating system. Errors in the disk file allocation table may report incorrect free space to you or to applications.

Bitcoin cannot run on a computer that has hardware problems. Laptops commonly fail because they have undersized cpu coolers that get plugged up with lint. Overclockers usually overclock until just before the computer crashes all the time, but Bitcoin won't tolerate a CPU that makes even occasional calculation errors from overclocking. Your computer crashing will also cause disk file system problems, you should do a disk check on each drive, and reboot when prompted.

As long as you have a recent backup of wallet.dat on a different media, your bitcoins are safe. There are 100 addresses pre-created in a keypool, only if you have made more than 100 transactions or manually added more addresses since the wallet backup may there be loss.

Post a single troll anywhere else and your account is in the penalty box. I also am very tired of this immature crap spewed all over the forum from people who have no preorder themselves. Either wait or cancel your preorder.
1711  Economy / Speculation / Re: How much would it cost to drive BTC to $100? on: January 24, 2013, 09:18:23 AM
It just got more expensive to buy almost the same amount of Bitcoins up to $100: $2,698,613. Lesson: if you want to accumulate Bitcoins in a bull market, do it fast in one order; you can't sneak little orders by the sellers, they will keep on bumping up their prices.

BTW, my previous screenshot is a perfectly executed hoax, nobody has $1.3M ready to buy Bitcoins - you can crash now, market.
1712  Bitcoin / Project Development / Re: [BOUNTY claimed] Help test version 0.8, blockchain upgrade on: January 24, 2013, 07:46:44 AM
I filed a gitbug about the repeated wallet warnings after salvaging based on the testing above.

Was reversion to an older version such as 0.3.24 expected to work? I can spend some time testing if a 0.8.0 branch (unencrypted) wallet can be used with 0.3.24, with or without walletupgrade, if the datadir is otherwise cleaned, find out which log file 0.3.24 complains about, etc.

Is there a later 0.8.0 target Win32 pre-build? The bluematt repository seems down.
1713  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: January 24, 2013, 12:11:50 AM
Does it save them anywhere now? I've recently found that mine closes itself after finding the address (Resulting in me leaving the computer for hours to find it closed after spending days generating one)

>vanitygen
Vanitygen 0.22 (OpenSSL 1.0.1c 10 May 2012)
Usage: vanitygen [-vqrikNT] [-t <threads>] [-f <filename>|-] [<pattern>...]
Generates a bitcoin receiving address matching <pattern>, and outputs the
address and associated private key.  The private key may be stored in a safe
location or imported into a bitcoin client to spend any balance received on
the address.
By default, <pattern> is interpreted as an exact prefix.

Options:
-v            Verbose output
-q            Quiet output
-r            Use regular expression match instead of prefix
              (Feasibility of expression is not checked)
-i            Case-insensitive prefix search
-k            Keep pattern and continue search after finding a match
-N            Generate namecoin address
-T            Generate bitcoin testnet address
-X <version>  Generate address with the given version
-F <format>   Generate address with the given format (pubkey or script)
-P <pubkey>   Specify base public key for piecewise key generation
-e            Encrypt private keys, prompt for password
-E <password> Encrypt private keys with <password> (UNSAFE)
-t <threads>  Set number of worker threads (Default: number of CPUs)
-f <file>     File containing list of patterns, one per line
              (Use "-" as the file name for stdin)
-o <file>     Write pattern matches to <file>
-s <file>     Seed random number generator from <file>

Unremarkable, as they are based there with local college "talent" from there. The gubmint will probably do that just for the economic stimulus to a local tech business in a region that is only notable for cows and corn and innocent farm girls fresh off the bus in Hollywood. Look at the soil around Des Moines. You can't build on it, you can't grow anything in it. The government
says it's due to poor farming.

How come there aren't like... five million copycat sites of this yet?  All I can think of is BTCDice and it doesn't even seem to work?

Bankroll - how much does an upstart site need to hold off someones martingale? How about multiple whales playing at the same time?

SD (and competitors) need to be able to go out thousands of coin while waiting for the player to bust.

A "Martingale" is a failure betting fallacy, and a casino can only hope for players so stupid. It will result in a player going bust far quicker than the casino. If the bet unit is 1 at 50% odds, and the betting can continue for many rounds of doubling (say 10 rounds before hitting a limit - which is 1024x) then there is little risk to the Casino. Even a win with this "strategy" means the casino wins 1+2+4+8+16+32+64+128+256+512, and if the player wins the final bet the player's total winnings is 1 bet unit; however the player has statistically paid more in house edge when betting those amounts then the total winnings; the bets are independent everywhere except in the player's mind.

Google "risk of ruin". The profit/loss of a casino over the long term is a random walk, and there is always a very small chance that any casino will go bust. If I have a 1 BTC coin flip game and have 5 BTC in the bank, I can let a player play four times with zero risk; there is a one-in-32 chance that the player will bust me in five flips. If I let the player play an infinite amount of time, there is a 100% chance the player will bust me (at some point in the future, maybe after the sun explodes). With a house edge, I can make the risk approach zero within a normal timeline.




If I open a casino tomorrow, there is an extremely small chance that every bet ever placed at the casino will be won by the player. One would need to adjust the gaming rules and house edge to minimize the chance of casino ruin to something you consider safe - do you want a 1% of going bust; a .001% chance of going bust, etc? SD has minimized this risk while having a bankroll to pay out some very high rewards on the higher odds games.


Answering the original question, "why aren't there five million copycat Googles, eBays, Amazons?" If you do something first, and do it as good as any competitor might, there is market inertia that presents a barrier to entry for others.

Bitcoin also requires a computer that is operating correctly, it runs the CPU and drives at 100% for hours, and has low tolerance for bad math. It requires about 100 trillion CPU instructions to download the blockchain, all performed correctly. If you have a laptop that has the cooling fins plugged up with fuzz, are overclocking, have a SATA cable creating CRC errors, or have one bit of bad RAM, Bitcoin will find it.
1717  Economy / Speculation / Re: Anyone who invested at 32.. on: January 21, 2013, 04:51:42 PM


The amount of time that Bitcoin was ever above 20 was about 90 hours. A lot more people sold on the way down than bought in at the top.

Both of these are correct block hashes for the main chain; it looks like one p2p client you are connecting to might be serving you up a corrupted block 139548, confounded with some problem recovering to a correct blockchain. We would need to look further back in the log file where blocks up to 139548 are downloaded normally and then something happens to see when the problems started occurring and deduce what data Bitcoin might be receiving. If you can post the complete debug.log/db.log files from download start to blocks 140000+ on the web somewhere it might help.

If you want to skip quite a bit of downloading, you can get this torrent: https://bitcointalk.org/index.php?topic=94881.0 - -loadblock it's orphan-free blocks instead, which definitely shouldn't error.

Links seem to be nothing like the challenges indicated above.
1719  Economy / Speculation / Re: How much would it cost to drive BTC to $100? on: January 21, 2013, 12:53:43 PM
There are currently 65614.1 Bitcoins for sale on MtGox priced under $100. If you place an immediate order to buy all the Bitcoins available on MtGox priced below $100, and then bought .1 BTC of the $100 Bitcoins, the "last trading price" would be $100. The amount of money this would currently take is $1,087,817.82. Since you would be buying almost all the Bitcoins currently for sale in this exchange, you could maintain the $100 price cheaply, at least for the hour it would take other sellers to send more Bitcoins in.

You can do the same thing on a low volume exchange for much cheaper.

edit: it looks like MtGox doesn't correctly calculate the true price to buy xxxx BTC; the answer is currently $1,695,122 USD to buy to $100.

1720  Bitcoin / Mining support / Re: Phoenix 2.0 Error - cannot load phat2k & opencl on: January 21, 2013, 11:54:41 AM
If you are running from source, your largest obstacle will be building pyopencl . You did not state your platform. You can get a Windows compiled version here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopencl

couldn't be windows.  wouldnt have to bother with these dependencies he speaks of


Could be Windows.

Same problems here, there are no docs about the build versions at all. To get a suitable environment I finally installed:
Python 2.6.6
Python setuptools-0.6c12dev-r85381
Python 2.6 Base-11.5.23
Python 2.6 numpy-1.6.0
Python 2.6 scipy-0.7.1
Python 2.6 Twisted-10.1.0
Python 2.6 zope.interface-3.6.3

Most of those are pre-built here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

Then I installed boost libraries 1.42 (timedate, python, threads; multithreaded dll), and copied the boost_date_time-vc90-mt-1_42.dll, boost_python-vc90-mt-1_42.dll, and boost_thread-vc90-mt-1_42.dll to the windows\system32 directory

added Python to the path, added a HOME environment variable.

Installed full ATI Stream SDK 2.4.

I then got the pyOpenCL 0.92 (the last version that doesn't complain about kernels using deprecated functions), and built and installed it using MSVC9. Multiple fails to come up with this as my siteconf.py:

BOOST_INC_DIR = [r'C:\Program Files\boost\boost_1_42']
BOOST_LIB_DIR = [r'C:\Program Files\boost\boost_1_42\lib']
BOOST_COMPILER = 'msvc'
BOOST_PYTHON_LIBNAME = ['boost_python-vc90-mt-1_42']
USE_SHIPPED_BOOST = False
CL_TRACE = False
CL_ENABLE_GL = False
CL_INC_DIR = [r'C:\Program Files\AMD APP\include']
CL_LIB_DIR = [r'C:\Program Files\AMD APP\lib\x86']
CL_LIBNAME = ['OpenCL']
CXXFLAGS = ['/EHsc', '/DBOOST_PYTHON_NO_PY_SIGNATURES']
LDFLAGS = ['/FORCE']


Or something like that... with all that, now I can run phoenix source.

 A step-by-step 'how to install python for phoenix.exe' would be many many steps, it would be nice if Jedi95 would just document building, especially how he makes the EXE since I have yet to duplicate the binary he distributes.
