email and PM friedcat is good point to start with.

Check your cabling, might have fried.

you joined only a month ago. would you have been here 2 years ago, you would have seen this several times … no surprise.

If you have the pre-paid perk enabled (My Account > Donations and perks, the "immediate pay" options at the end of the page), you are getting paid for every block as soon as it is found and gets at few confirmations (I believe, possibly just one).

The last block that appeared in the block list when you posted was at height 237798. The block in the main chain (the "real" one) at this height was from ASICMiner, not BitMinter. Than means it was probably a stale block, and it still show as "processing" in the list until it is found to be stale. Maybe* this will happen when the next block is found, but as far as I understand, this block will never make it to the main chain and miners will not be paid for it (and it's perfectly normal because it yielded no earnings to the pool).

So, basically, I think you have not been paid in the last 8 hours because of a very unlucky round (6 hours), with an unlucky outcome (i.e. stale), followed by another unlucky round (4 hours), and while I wrote these line, we found one at height 237825 (phew!).

Now, the bad luck is probably going to end, and you will see your unconfirmed total increasing (it will be confirmed immediately if you enable the pre-pay perk w/ a small donation).

Finally, if you're not yet aware of how PPLNS works, you had to "fill" the last 10 shifts when you started mining, meaning initial revenues were lower than expected. But should you stop mining now, you will still earn revenues until you don't have any remaining work shares in the last 10 shifts, so it's a "symmetrical" delay in payments when you start/stop mining.

Hope that helps...

tl;dr: We have been very unlucky in the last 8 hours. Keep mining and with some luck your earnings will catch up with expected ones.

*edit: maybe => yes indeed!

To be honest, if someone asked me what i was doing with this, I would probably say "Search for Aliens, did you ever hear about the SETI project? And of course have my main computer ready running Folding@home or SETI@home

Im not sure if I should go with SETI oder Folding here... the SETI thing sounds a little more nuts. The other thing on the other hand is something people won'T comprehend. "You are folding proteins? What the f*!"

Browse the YaCoin development thread, especially after page 13. There's a whole lot of discussion on Scrypt's memory requeriments, since YaCoin uses a variable formula.

Please add NMC to stratum... Pretty please!?!

Check your history in the website, it should show the dividend, the emails are not definitive. Otherwise, contact burnside if you have confirmed that the dividend did not reach you.

Did you buy shares after divs were already paid?

Slush's pool != the entire network.

These are very difficult questions to answer. Scrypt is not just a "simple" algorithm that is the same everywhere like SHA-256. It has values that can be changed, and those values can have significant effects on the viability of something like an ASIC. It is also hard to predict how this viability might change over time.

For example, LTC used figures that mistakenly were thought to be GPU-resistant, but they were not. The same could happen regarding ASICs without a deep amount of research. And it could still be wrong.
