Its my 1st time to post here.
Ive been here from the time that the site was hacked and all i can say is " Slush is da mheen!" hats off to you man.

already confrimed but no reward?

The same apply to you. Too small number of shares comparing to total number of shares.

Bah, this should still have received around 0.0001, unless you did those 135 shares towards the beginning and then stopped mining.  As such, your score decay would've zeroed it out.

Seems like it should get at least a nano-coin, unless those shares aged, like you said.

For anyone newbier than me:  share aging is designed to discourage pool jumping.  See https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002 for how it works.

Sometimes an honest miner loses connectivity, has a reboot that takes longer than expected, inadvertently terminates the mining app, etc., and ends up with zeroes -- just part of the adventure

On a total side note.....

Which means i've got to start generating reports for the end of this year (this is my first year bitcoin mining and barely have over 0.01 BTC so far, not counting the pool)

May have to get Slush to send me a T4-BTCI form at the end of the year ( revenue canada income tax form lol )

OMG too freekin' funny! I was looking in the comments on this article and LMFAO'd on this:

"Total reward:  Unconfirmed + Confirmed " is frequently going down, thought it was me miss reading at first but it is happening, anybody know why?

You see this when a block becomes orphaned - recently we have had a few - last 2 were blocks 233158 and 233303. Before they are marked as orphaned, you see them adding to your total. Then when they are marked as orphaned, your total goes down by the amount you would have earned for that block.

Thanks, from a fellow LFC supporter

No problem hope we win today.

Also, the fact that a block may be marked as orphaned is the reason we have to wait for 100 confirmations before a block is confirmed. This is a block chain rule - not something that Slush decides to impose willy nilly...

Don't know about anyone else but I am really enjoying an uneventful day!

Can anyone explain the effect of worker difficulty?  I see where it asks the expected hashrate of the worker and then raises the difficulty for that worker if the hashrate is very high.  What effect does this actually have?  What effect does it have on a worker to have too high or too low of a difficulty set?  I googled but could not really find it explained.  If someone has a link or an explanation I would appreciate it.

is block 233334  orphaned?

Looks like it.  Blockchain seems to be accepting this one from BTC Guild.

Nothing. Your submitted shares have value x difficulty. You'll see less submitted shares from cgminer but they will be multipled by the worker difficulty to calculate your score. For very very short duration consecutive blocks you may get screwed once in a while because you work did not submit any shares at a higher difficulty. n my opinion stick with the lowest granularity unless you have a large Caterpillar bitcoin mining machine.

It's basically getting paid by the shovel or by the bucket for your work.

I still don't understand the "Suggested difficulty" field.   Dose it have some thing to do with long polling? If my connection is bad do I set it higher or lower?

It means that you aim for a share with more worth. E.g. a share at difficulty 1 is worth 1 share, 2 is worth 2 shares.. and so on. The difficulty refers to the target set for your hashes. At difficulty 2 there are half as many possible hashes which would contribute a share when compared to difficulty 1.

The reason it's useful is that with a very high hashrate (>2GH/s) you'll find so many difficulty 1 shares that it'll use up a lot of communication and it floods the server with requests.. so if you look for more difficult shares, you still (theoretically) get the same rewards, but the communication with the pool server is lower.

Hope that helps.

Excellent!  Thank you both!

Slush's real name is Marek Palatinus: http://blog.bitcoin.cz/author/slush/

There is this whole thing called vanity mining where people generate millions of bitcoin addresses just to find ones that contain a specific string

Who is Marek? was this just a chance address or did you engineer it? just curious.

Regards to recent higher invalid ratio - it was caused by the move of bitcoind to another datacenter and by poorly connected bitcoind to outer world. I made some changes and bitcoind should be well connected now.

17719 seems to be suspiciously light in rewards.  Thanks

Slush, I find the same. Something odd with 17719...

It does appear light.  I'm sure Slush will recalculate the reward...

[fourd00rgtz]

agreed, kinda 1/2 of normal
