What happened with Block 17754?
Blockchain says only one transcation in the block, the generation of new coins. is that normal?

I wouldn't say it's normal.  But I wouldn't say it's abnormal either.

I happens every once in a while.  Hopefully less and less as btc becomes more popular...

It was 15sec block (for the network).

Yeah, I was about to add...

Look at the time stamps of that block and the one before it and you realize it's not that far fetched.

[nyclogan]

ok, gotcha. I was not aware that there were blocks like that.
Thank you.

Although I have an office near the explosion place, I'm fine!

Natural gas explosions can be very powerful.  Had a large gas main rupture under the street about 30 meters from me when I was a kid.  A motorcyclist was riding down the street at the time.  He laid the bike down and I watched it disappear into the hole -- a heartbeat later the fireball bloomed and took out 5 houses around the rupture and knocked me back a couple of meters.  Don't know where the motorcycle ended up, but I think the rider was ok because he was flat on the ground when the gas ignited.

Slush, do you know much damage was done to the building & surrounding area?

All backends seems fine, I'm not aware of any problem. Also most block rewards are fine, so there's no indicator anything is wrong with the pool. I wouldn't be surprised it is yet another routing problem on the internet, as I saw many times in few last weeks :-/.

Seems 17759 is also pretty odd. I have 208898 shares but zero earnings. Is that normal?

How long would it typically take for you to generate 208k shares? if it's significantly less than 5 hours that would indicate a connection issue at the end of the round which could cause it, otherwise it's probably a miscalculation.

I was disconnected towards the end due to a strong thunderstorm passing over the area.

Does this mean if I get disconnected towards the end I don't get anything for the shares I produced?

Soooo bad luck at the moment, 5 hours, 6 hour blocks and lots of 2 hours as well

Depends on how long the outage was. Score is an exp function so your earning degrade to 0. I'm not sure how long it takes. I have been thinking listing the shares on the stats page isn't the best metric. Have score and total score would be better since those are what your earnings are actually calculated on.

I know why the functions are there, but its effects do seem a little harsh. Maybe it could be reduced a little? Otherwise those with massive rigs could switch do the opposite of the normal problem, run them on a PPS pool, then they notice its been 45 minutes here switch.

You can't predict the end of a round, and you can't mine the end of a round and expect more coins than normal.

The only way you can earn more than expected is by mining the first few minutes of a round and then mine else where. On average that will earn you a bit more than PPS.

[genpayne]

Surely if the rounds been going on one pool for 45 minutes, Then no matter how long the round continues, thats 45 minutes where you are being paid on a PPS. You then earn a few shares from the pool with considerable value. If the round ends within a couple minutes, its not much but you're miners haven't lost much.
If its a few hours, then for the 45 minutes you have been making coins while everyone else here has shares which value is now void.

Now whether 45 minutes is the sweet spot I don't know, and without looking into the maths properly / how much you get per share at a PPS i can't be certain you would earn more, but It seems probable.

Will work it out later. Hopefully you are right and the numbers will prove me wrong!
I mine on a fairly low power system. 40Mhash. If my last share is 30s from the end of the round I seem to get twice as much as if its 2 minutes!

Ok, I am surprised that the scoring system works that way....

It means even if I am an ASIC miner if I have an outage of 90minutes due to a storm then I lose all my shares value. Everyone else profited from my shares. So down time is my enemy.

How does the score system work? (I am sorry for my ignorance!)

----------------------

The thing that came to mind though is the following after being surprised by this part of the score system:

If I run really high difficulty shares...let say 512...and I therefore submit larger shares but less frequently...is this the reason why I earn alot less?

I noticed if I submit very low difficulty shares with a very high frequency...my score seems to stay very low (closer to 100 than 1 billion. Yet, if I submit shares at 512 difficulty every minute, my score goes into the hundreds of millions over time. I assume from watching this that my delay in submitting very high difficulty shares is actually hurting me in my score. Is this correct? If so, then this deeply discourages using high difficulty...right? I can see this turning into an ASIC-festival of people submitting diff1 shares. With BFL coming out and delivering (a minute amount) of ASICs...I assume this is going to be a bandwidth problem in the future, correct?

I eventually decided to run at diff-1 because the super short rounds didn't give me much of any chance as an ASIC to submit the higher difficulty shares.

I find myself scratching my head as what is the right thing to do. It seems to discourage any lapse in submitting shares, even if only a minute between submissions.

I also understood that a low score in 4 digits is better than a high score in the billions. Correct?

Read this to see the exact formula's used. I haven't time to eleborate more on that now considering I have an exam in under an hour, but I shall work out the calculations later.

It seems to me the formula was set when the difficulty was lower, making the share time also lower.
So now the round times are longer I think it could possibly be flawed. Without any actual maths put into this all it is is speculation so I could be completely wrong.

But yes, I have no idea how things effect ASIC. Best  to read that and work it out for yourself.

Probably shouldn't comment since I haven't had a chance to read those yet, but I did mention above about how I thought the system was outdated.
Judging by the hash rates in the top of those they aren't very recent.
If im wrong, please dont hang me! I'll apologise for my ignorance once I have had time to look at things properly.

4.2 and 4.3 are the important ones - 4.1 is just background. They are from last year, but the score method is the same now as it was then.
