From what value is this donation is calculated? From unconfirmed reward, confirmed reward or reward sent? I've just got a bunch of rewards and nothing was subtracted.

All displayed rewards are already displayed without donated amount.

All displayed rewards are already displayed without donated amount.

OK, I understand. All values are net. So essentially I "donate" some percent of the shares, don't I? In other words, you get the donation when the block is found. And If I change the donation percentage, it will not change the rewards for the blocks already found, only the future ones. Correct?

Exactly.

Is there some problem at mining.bitcoin.cz?  The cluster performance has been at over 13350Mhash/sec with 275+ miners for over 6 1/2 hours looking for Block 174 on the site.  There is a 50/50 shot at finding a block within one hour and a 95% chance of finding a block in under 4 1/2 hours.  At over 6 1/2 hours, what are the odds?

[ronaldmaustin]

Miscalculation on my part.  This site says, in effect, that the 4 1/2 hours would be in addition to the  1 1/2 hour average time to find a block.  So at 6 hours it would be 95% and we are at 6 1/2.  So, could happen.  Did happen, I guess.  http://www.alloscomp.com/bitcoin/calculator.php  Just out of curiosity, though, is there anything that could malfunction on the mining server that would not be apparent to me as a client, where I'd just be running calculations and submitting potential blocks?

Paying back probability for the 3 consecutive one's we found this morning in about 50 minutes.

[ronaldmaustin]

Suppose I could look at it like that except one of the blocks found was mine :-(
Thus far, I 've generated 150 bitcoins for collective mining and collected about 100.  So I am keen on the idea of probability payback.

Lost account password. What to do now?

Lost account password. What to do now?

Make a new one.  It's free.

I hope the reset password feature will be ready today...

[slush]

So, could happen.  Did happen, I guess.

Yes, time to time this happen. And 76000 shares per block is only 5x more than average, so nothing impossible.

Just out of curiosity, though, is there anything that could malfunction on the mining server that would not be apparent to me as a client, where I'd just be running calculations and submitting potential blocks?

Server problems can happen, of course. In this situation your miner will receive error status that share was not processed (HTTP status 400 or 600 and error message).

[m0Ray]

Lost account password. What to do now?

I have only 2 workers and it can work for me. But what if someone has 20?

Then this will be another reminder for them to either
1) Not forget or
2) Write it down in a secure place

Slush, I posed the question a few days ago on here as to why a person could not keep the genuine found block for themselves and pass on all of the worthless blocks on to the miner.  Someone said the block, as I generate it, is signed with the key of the mining server (or you).  I understand that, but upon thinking about it a little bit, how is that done since the bitcoin server that I'm running simply logs into mining.bitcoin.cz on port 8332 with my login and password.  I don't ask from the standpoint of anyone trying to cheat anyone but rather . . .

Several days ago I hit upon a block while mining on my own and it did not go through.  I sent the logs here but never got to the bottom of the issue.  I like pooled mining, but I'd also like to try again on my own and I began to wonder whether the pooled mining had somehow gotten in the way of mining on my own.  I was speculating that perhaps my pooled mining efforts had changed something in the poclbm folder and instead of trying to award my found block to me, bitcoin.exe was trying to award it to the miner (thorugh poclbm.exe which is used for local mining as well).  Neither of us got it, of course, and I am hoping not to repeat that.

Maybe my question isn't too clear, but basically I'm asking if my local miner batch file says:

start /DC:\bitcoin\poclbm_py2exe_20110104 poclbm.exe --user=ronaldmaustin --pass=xxxxxxxxxxx --device=1

and my pooled miner batch file says:

start /DC:\bitcoin\poclbm_py2exe_20110104 poclbm.exe --user=ronaldmaustin.dog --pass=xxxxxxxxxxx --device=1 --host=mining.bitcoin.cz --port=8332 --w=256

could this create any issue when I switch back and forth between the two.  And then this begs the next question (my first) which is that unless you are sending some work to me to calculate along with some security scheme for yourself so you receive the good blocks, does the security to prevent this in files modified elsewhere on my PC?

[ronaldmaustin]

Boy, I muddled that last question.  It should have read "does the security to prevent this ...".  I guess what I'm asking is if the work you send to my computer is any different than the work my own bitcoin server would send to me.  I'm guessing so. 

If not, I was assuming that the security scheme for assigning the block to the miner must lie somewhere on my PC and could have interfered with my own mining.  I'm hoping a bunch of people jump on here and say, "No way.  You just don't understand how it works."

Hey, sorry, but I completely don't understand what's your question...? When you want to solve blocks standalone, simply connect your miner to your local bitcoind.

Several days ago I hit upon a block while mining on my own and it did not go through.

It is sometimes possible, you can find a block, but anybody else (maybe the pool :-) send valid block just a second before your own solution. Then your block is not counted...

I like pooled mining, but I'd also like to try again on my own and I began to wonder whether the pooled mining had somehow gotten in the way of mining

If you connect your miner directly to own bitcoind, there is no way how can pool interfere with your mining effort. (if this is core of your question)

[walidzohair]

i noticed that when the server have more miners it is not more likely to find blocks (30k miners) look at the last found block id and the current block id.
but whn it have less miners it have more probability to findmore blocks !

maybe i am wrong or new but maye also when it ahve lot miners somthing go wrogn in dividing work .. or miners just get workand then disconnect shortly without the server re-assigning thier work (lost possibility).

can any one enlighten me ?

[slush]

maybe i am wrong

Yes, you are, completely. Current average speed for ~50 last blocks is faster than long term average for corresponding Mhash/s is (approximately +10% faster).

You cannot pick short-term peaks from last days, where we found many blocks in a row. We have still only 8% of bitcoin network (so in long term pool should find every 12th block in network. When you look at last 47 blocks, eight of them are from pool, so 5,8 average (which is significantely less than 12).

I made pool to help standalone miners smooth their income, not to help people with stealing CPU power from university computer lab.

no, I am using google app engine (https://appengine.google.com/) free quota.
It have 6.5 free "cpu hour" (which is, only 3 real hours) per application.
10 applications for each user (verified by SMS).  That is .... around 50G hashes per day per mobile phone number.

It is written in java, and I will release the source code in a few days.

Hey, sorry, but I completely don't understand what's your question...? When you want to solve blocks standalone, simply connect your miner to your local bitcoind.

Okay, I'll try to keep it simple.  When I generate a valid block worth 50 bitcoins as part of the pool, how do you prevent me from keeping the block for myself when I find it?
