Will be sending a bit of coin next time I do a transaction. (To save on the fees.)

Already did all addressed for him. He paid me well for each.

Wow, how long did it take you and what equipment were you running?

A bit over a week but he did waaaaay... over what I asked in this thread.

Also having the GPU hash/CPU hash error. I'm running Catalyst 13.11 and downgrading is not an option for me. Also AMD APP SDK v2.9, willing to downgrade this if this is the issue.


Having this error as well, and also downgrading is not an option.

Anyone have any solution for this? 
Yes, the solution is to rewrite vanitygen in opencl 1.2. Of course, why should this happen, the last time someone donated to samr, it was 0.001 four months ago, and then $2 worth a year ago.

"downgrading is not an option"...heh



Wow, I'm ashamed. I use this tool all the time. I didn't even think about that. I would be one of those people leeching off of his fantastic work, and telling him he needs to update the tool.

Will be donating very soon.

Edit: deepceleron, what is his donation address. :s

Found the address. It was sneakily hidden in a code box.

For everyone else that wishes to donate his address is: 1samr7UZxtC6MEAFHqr1h3Kq453xJJbe4

6  Bitcoin / Development & Technical Discussion / Re: Pure Python ECDSA implementation? on: January 26, 2014, 11:08:03 PM
Is there a pure Python ECDSA Secp256k1 implementation? I don't care how slow it is, because calling libcrypto in a loop gives me Segmentation fault every 3-4 million loops. I'm using Joric/bitcoin-dev implementation and I've tried to find the cause with gdb, but give up on it, have no more nerves for it.

Using some utility through RPC is not an attractive option because of overhead. If anyone has a link to a native Python solution I would be grateful.

Sorry, but just a slightly off-kilter question for you... Why not use C++? I assume you may develop Python on a Linux platform, so development and IDE usage would be similar. Hell, even the syntax is similar. With C++, however, you get more control from your code.

Was going to post that link. Looks like you beat me to it.  Roll Eyes
7  Bitcoin / Bitcoin Discussion / Re: What is the best paper for a paper wallet on: January 22, 2014, 02:58:25 PM
Here is what I do.

I print and make my paper wallet offline (on white card stock) using this website's source code, found on GitHub.

I've purchased some stickers and bags from the website, Canton Becker, the developer, handles all aspects of the website. I've even purchased custom amounts of things, that are not an option on the website. Anyway... I then spray one side of the card stock with Krylon Preserve It Aerosol Spray, Matte Finish I let that side dry for a bit (only takes about ~5 minutes) I then cut out the design and fold it like shown in this video or on his website then I place the stickers like shown. Lastly I put them in a bag that comes with the wallet and... Tada!

Do you hate me, man? Lol. I don't want to sound rude, but I specifically said "available today", not pre-orders. Price is not an issue. Smiley


I'll say it again...


cointerra.com

Buy it from someone who preordered one for January or whatever.

Thank you for your valuable feedback. I will take your price suggestion into consideration.   Roll Eyes
11  Bitcoin / Bitcoin Technical Support / Re: What if I delete blk0001.dat files on: January 14, 2014, 03:20:57 PM
Yesterday I installed and ran butcoind on linux server and since yesterday it consumed around 10 or so GB of disk space so what I am thinking is what if I delete old files of block info like I have upto blk12345.dat can I delete upto blk5000.DAT will that create issues ?

In short, yes. It will probably cause issues.

Edit: Unless you're looking to delete them all and redownload all of the blockchain.

Also, you'll need all of the blockchain, which means multiple blk*.dat files that take up allot of space.

If you don't want to take up so much space you should look into a alternate client, such as Electrum or MultiBit.

All right! I'm waiting for my order at cointerra that should delivery in February, at today I'm mining by 500gh/s bitfury.

Seen the long pre-order queque in every mining hardware site I'm asking to myself if it is the time to order next miner? and which one?
I was thinking something greater like buying chips 28nm from cointerra and than make my own miner hardware. Anyone got experience about it? http://cointerra.com/chip-veterans-form-new-startup-will-sell-high-end-bitcoin-miner-14000/

give your answers!

I've not heard anything "super-bad" about CoinTerra, thus far. Don't think this gives a green light, however.

One question
Why would you trust someone to create a vanity address for you as he will know your private key?
He isn't:

If interested just PM me for a my part public key.
I'll leave it as a fun adventure for you to figure out why.

One question

The technique used is Split Key Generation so there’s no risk of having your private key compromised.

They pretty much summed it up.

20  Other / MultiBit / New "Blank" MultiBit .wallet File With Vanity or No Private Keys on: January 01, 2014, 12:48:05 AM
Is it possible for someone to either write a quick script to remove a key from a multibit .wallet file or create a new MultiBit .wallet file with either no keys in it (but multibit would recognize the file) or create a .wallet file with a specified key in it.

I'm wanting only Vanity Keys and Externally Generated keys in my multibit wallet. Is this even possible to do?

I would even accept an upload of a blank MultiBit .wallet file at this point.
