What is relevant on people's own stupidity?
If you want to play on exchange send your funds there.
Slush is mining pool not bank so discussion about this is what I said - nonsense and garbage.
Consider for a moment that ASIC miners don't have a choice. We generate coins faster than they are confirmed. I didn't want to have almost 10 coins there. I had the default setting set at 1.0 Unfortunately, the pool fell under the attack. There is no "right" way of doing it if the confirms take about 5 hours per BTC to clear. Right now my counter is at 6.65847142 BTC instead of somewhere around 9~10. something. I haven't had anything deposited since the "2013-04-23 16:31:27" according to my offline wallet transactions deposit list. Now that I am checking things carefully I just noticed that one of the deposits went missing into thin air. The pool records says it deposited another coin at "2013-04-23 20:31:27" yet that is not showing up in my wallet and has gone missing. So it seems there is a missing coin in there somewhere. I believe that is roughly when the pool got attacked and went down. If that is the case I am up to about 11 coins and some fractions. Again, it's not like some of us have a choice in the matter. The confirms take quite some time. (Alright, I am going to go ahead and crunch the numbers on my account and see how much has gone unaccounted in the meantime.)

OK, I went thru all reportings of wrong block rewards. I fixed some rounds, but currently it looks to me that they're fine and reported differences are in the range of common variance (+ some downtime during the pool recovery). So I'm going to process pending block rewards and payouts in few minutes.
Automatic payouts will be still disabled until tomorrow and I'll do manual payouts irregularly by myself, because I want to keep eyes to payout mechanism for some time. But if everything will work well, I'll enable periodic payouts every 15 minutes tomorrow.

Just my chip in on the earnings during the database downtime. I actually thought i wouldn't get anything. Was mining on an ec2 voucher (*i've another ($100) which i'd take offers on (one per account)(apologies for the shameless plug)*) and it ran out mid-down time. Of course when slush said he'd pay out based on performance as soon as things are up... and i knew i wouldnt be mining... So I was extremely happy to log in and see I had been credited. I want to thank slush for his dedication and getting things back up so fast! On a side note theres a newbie who's about 10% under though from my maths. Might be worth looking into https://bitcointalk.org/index.php?topic=187689.0Hmmm Now that you point it out I have some blocks that seem to be not calculating correctly either: # Block found at Duration Total shares Your shares Your BTC reward Block # Block value Validity 17680 2013-04-25 11:28:30 0:57:54 5689208 559 0.00180916 233057 25.21487399 11 confirmations left 17677 2013-04-25 04:53:30 2:15:34 12167460 1249 0.00205932 233015 25.30640678 confirmed 17661 2013-04-24 05:07:55 0:35:37 3581506 325 0.00123194 232863 25.20775000 confirmed my calculation is that the first one should be more like .00242796 and the second more like .00254576 Those were just the ones I looked at because they are lower then the rest. Maybe I am calculating wrong? EDIT: added a third which I calculate should be more like .00224170 |

only block that looks iffy is
17661 2013-04-24 05:07:55
looks like 1/2 payout, but i can live with that.

Mine is <50% of normal reward for that same block as well. rest seem fine. Probably just a bad round for me. K. |

I find EC2 specs to be the most confusing opaque metric there is. Other than comparing one instance to another I have never figure out exactly what their values mean. |

There seems to be something fishy about blocks 17662-17669. I seem to have submitted only 10% of the usual shares. Might have been connectivity. Not that it's of any consequence, I was only mining with my 71MHash/s iMac, just reporting and asking others if they find the same.

Hey slush, any chance you can put the formula used to calculate rewards somewhere on the stats page or is it more complicated than I have been given to understand?

Well that was the rough estimate version back when a block was worth 50. You can do the same thing now and get a rough estimate with 25 instead, but I was thinking the less rough, including fees and other factors version. EDIT The one genpayne posted in the newbie thread is the closest version I have seen but it does not account for the scoring system: (Block Value * 0.98 * your shares) / total shares |

Might be worth looking into https://bitcointalk.org/index.php?topic=187689.0Was it profitable? What kinds of spec did the instance have? Nowhere Near! I made 0.01587451 BTC from it mining at least 30 hours ($63). But it was more of an experiment/learning process, I had no other use for the voucher. I would only buy the other one from me if you have use for AWS services other than mining. Its Valid on - Amazon Route 53, VPC, EC2, Elastic MapReduce, SES, CloudSearch, ElastiCache, AWS Elastic Beanstalk, SQS, AWS Data Transfer, SNS, Simple EDI, DynamoDB, CloudFront, RDS, Simple Notification Service, S3, and SimpleDB And I think it needs to all be used by the first of September. Open to any offers from 0.35BTC up. To a reputable member here you get the code, then pay when you know it worked. If not, payment upfront. The spec was - Cluster GPU Quadruple Extra Large 22 GiB memory, 33.5 EC2 Compute Units, 2 x NVIDIA Tesla “Fermi” M2050 GPUs, 1690 GB of local instance storage, 64-bit platform, 10 Gigabit Ethernet Running Poclbm on both GPU's and cpuminer. *Edit* For those that don't know amazon also have a free tier. Its pretty pathetic but to leave it going a year would probably be worth the time setting it up. |

I couldn't say. My mining experience started with this. Had the voucher and figured it'd be a fun way to waste it! I think the GPU's were getting 50Mh each but that could be wrong. Then about 16MH from cpuminer over all the cores. If those values sound out its probably my memory playing up. Tend to think if it was massively profitable people would have realised by now. EC2 is hardly new |
