A big thank to chromicant ! My hashing speed have done more than x2 ! Here are all the steps i followed one a debian (testing) system to obtain the compiled version : sudo apt-get install git automake1.7 libc6-dev libcurl4-openssl-dev
#YASM : http://pkgs.org/download/debian-sid/multimedia-main-amd64/yasm_1.1.0-0.0_amd64.deb.html
wget http://ftp.br.debian.org/debian-multimedia/pool/main/y/yasm/yasm_1.1.0-0.0_amd64.deb
sudo dpkg -i yasm_1.1.0-0.0_amd64.deb
git clone https://github.com/chromicant/cpuminer.git
cd cpuminer
git checkout remotes/origin/sse2
cd x86_64/
./build.sh
cd ..
./autogen.sh
./configure
make Here is the compiled binary : http://dl.free.fr/tjbLyHclUHope it will be usefull :p |

Already tested : I've not investigated further, because there's no error reported by wine nor by bitcoin-miner (even if i put a wrong login/pass). EDIT : If it helps someone, it seems related to libpthread : Backtrace:
=>1 0x7b845932 in kernel32 (+0x25932) (0x7e2d4758)
2 0x00427dad in bitcoin-miner (+0x27dad) (0x7e2d47c0)

slush, i've juste been disconnected from http://mining.bitcoin.cz and cannot log in again (Your username and password didn't match. Please try again.). Are you working on something or is there a problem ? Someone else is concerned by log in problem ? EDIT : Problem solved after a password reset... |

The best cpu miner is still ufasoft's. I'm waiting for the linux adaptation :p |

I've recently discovered this SDK for OpenCL with intel plateforms (windows only for now...) : - http://software.intel.com/en-us/articles/intel-opencl-sdk/It requires SSE 4.1, so, only cpu is used for now (yes, opencl is designed to be used by both cpu and gpu). FAQ extract : "Will the Intel OpenCL SDK support Intel integrated graphics (processor graphics), and when? Intel will support OpenCL on future tools and platforms.Intel is evaluating when and where OpenCL support will intercept our products, including processor graphics, but no announcement has been made." Any volonteer to add this in existing miners, if possible ? Will it improve speed compared to the SSE2 asm version ? |

It may be a good security to generate 1'000'000'000 addresses to avoid someone to send your wallet over the web :p

With a 2'000khash/s (2Mhash/s) you can obtain about 0.05 BTC / day on a pool. So, on solo, it would take an average 1000 days to gain a block of 50 ?  ( the calculator says 957 days). Good luck |

I've a problem with the new version of the 4way miner (previous version of 20/02 worked fine). At launch, it says "temPowerStatus" not available in kernell32.dll and halt.
|
|
|
|
ALSO, can difficulty ever go down?
Yes, it adapts itself by looking at the past hash speed (or block generation speed) to stay in a average speed of 10mn per block (if i remember correctly all i've red there). |

The sign generator has been updated to add the bitcoin mail address (see below)
|
|
|
|
To know the default used architecture on debian based distrib : dpkg --print-architecture |

New function : you can now send email to any bitcoin addresses ! How to do this ? Try sending a mail to "your bitcoin address @ bitcoin-contact.org" and your message will be added on the site. By default, the email address you send with will be used in the 'From' field. So don't hesitate to look at the FAQ to know how to customise that and eventually use the special syntax to show or hide fields. Also, two new pages : - FAQ- AboutNext steps : - pseudonym registration - email and bitcoin addresses verification (people who want to associate an email address and/or pseudonym with some of his public bitcoin addresses can do it) |

Launch the jgarzik's CPU miner with "--threads 2" and you should go back to 2x1100khash/sec like that :
HashMeter(0): 4537024 hashes, 1081.21 khash/sec
HashMeter(1): 4537024 hashes, 1042.21 khash/sec
You should not generate in the official client (or server) at the same time of course.

Thanks grondilu for comments and donation  Your two suggestions have been applied. |

Good idea. But nobody near me yet :p Also, messages within the site would be good; or maybe a forwarding email address @tradebitcoin.com?
This seems to be a very popular feature. It will be a week or two before I'll have enough free time, but I'll definitely be adding something. => We may do something together with bitcoin-contact.org for the messaging system ? |

Translations are available here : http://bitcoin-contact.org/locale/If someone want to add another language, he can use the english model and attach file to his post. There are 26 strings to translate, not too much work :p Thanks in advance for volonteers. |

Indeed, this can be done by checking transactions. Several choices seems possible :
- send random amount to yourself => site web checks for the specified amount and address in transactions list
- send random amount to another of your address => not sure if the address of sender will always be in the transaction
- send 0.01 to a new generated address which i own => same
Private key exporting is too complex for this use :p

Hi, here's a new bitcoin site which aims to facilitate direct discussions between bitcoin users : => Bitcoin-Contact.org [BTCC]Usage 1 : Your receive a transaction and don't know from who it is ? Send him a message, he may see it : Future usage 2 : Discuss with a bitcoin user by sending him a mail to his bitcoin address @ bitcoin-contact.org It's very simple : - put your bitcoin address in 'from' (or nothing to stay anonymous) - put your bitcoin recipient address in 'to' - put your message => send For now, all messages are publics. I need to add some method to check a user owns a particular address to enable private messages. There'll be more functions with emails too, translating, etc. Details are on then todo page. Ideas and help are welcome. Don't hesitate to go to the tools page to generate a BB Code signature to put on this forum :p Donations for a poor cpu miner are welcome |
