Sorry for the short downtime. We are on 0.7 and everything should be ok.
Thanks ! onward... |

How does the pool take into account the miner's higher difficulty set point that would correlate to a lower submitted hash rate and the payout share?
It pretends like one proof of work mined at difficulty 32 is 32 proofs of work at difficulty 1. So the payout is fair, but there is a little more variance at higher difficulty. As far as I know this is how all the pools handle variable difficulty. If you want to know more about that I'd suggest you check out organofcorti's blogpost about it: http://organofcorti.blogspot.com/2012/10/71-variable-pool-difficulty.htmlCool, thanks for the insight, and I'll run through that blogspot ... |

Something like this (the 'Diff 32/8' means that the target difficulty is 8 and the submitted share had a difficulty of 32):
In your case with a speed of 24Ghps you may see a difficulty of 16. As for setting this yourself, no, currently that is not possible at BitMinter. It is automatically adjusted by the pool based on your hashrate.

And does anyone know if bfgminer supports the variable difficulty being talked about here?
Yes, for the past several versions. Your worker hashrate needs to be high enough, though. Roughly 20 shares/minute is the threshold I believe. I have a 1.6Ghps worker (~22 shares/minute) which never sees a difficulty higher than 1. A 12Ghps worker would see a difficulty of 8. We have one bfgminer setup with 24Ghps total, so I'm assuming we should see the difficulty rising. What this quickest way for me to check on that, and is the difficulty level something I can set myself? Thanks for your feedback... |

My apologies if you have already covered the subject, but ... what are your commits on the use of mining_proxy with the new ASIC boxes coming online?

I've uploaded some prerelease/alpha Windows builds of BFGMiner 3.0 for testing. ... Please verify your FPGAs/GPUs/pools/etc still work as expected. Note the new --show-processors option to view your FPGAs at a more detailed level. bfgminer-2.99.00 Win-64 been up about an hour now, nothing to report, everything is running well. |

User defined Stratum diff is already available. So I don't see the rush to implement it into a miner.
I do see reasons to implement a difficulty setting in the miner and hope this bounces up the list of priorities for BFGMiner. |

Is this using the PPA package, or self-compiled? If the latter, from tar or git? If the latter, is it possible you forgot to run autogen.sh in a long time and might have an old version of libblkmaker?
PPA: $ sudo apt-get install bfgminer used: $ sudo add-apt-repository ppa:unit3/bfgminer for the apt repository... BTW, is it better to stay with long poll in solo mode, or allow miner to move on to stratum if available? PS: if limited to Long Poll (--no-stratum) the "Cannot append template-nonce to coinbase on pool 0 (-1) - you might be wasting hashing!" stops repeating after each new block. |

I get an interesting message from BFGMiner 2.10.5 under ubuntu while doing solo mining:
[2013-02-16 10:31:46] Cannot append template-nonce to coinbase on pool 0 (-1) - you might be wasting hashing!
[2013-02-16 10:31:46] Cannot append coinbase signature at all on pool 0 (-1)
Using bitcoind for servers... Now, I have the same configuration running under window 7 against the same bitcoind's with no problems (i.e. Blocks are created and posted to the correct wallet). It only gives me this error under ubuntu. (btw, it's amd-64 client)
Tired of buying Window licenses, any clues?
