Even if you use Bitcoin through Tor, the way transactions are handled by the network makes anonymity difficult to achieve. Do not expect your transactions to be anonymous unless you really know what you're doing.

I'm in the process of upgrading one of the supporting bitcoind instances to 0.7. It has decided it needs to inspect the world for a while so share processing is down until it completes.
Mining, block creation and share recording are going fine (they use a different bitcoind). Payments and share recording btc amounts for shares will be back whenever it is done.

Are there any plans to support the Stratum protocol?

I have only just now heard of it so I have no plans. Does it provide any significant advantages to miners? |

It's supposed to be more of a benefit for the pool operator, keeping the network traffic to a minimum.

I have to wonder whether traffic's really an issue when you're working on high-difficulty shares... |

I can't remember how to do risk of ruin calculations on BTC pools, but I tried inputting the pool's current balance into a sim I made.
200 runs, 88 of them resulted in pool bankruptcy within 100 blocks. 61 of them (30.5%) resulted in pool bankruptcy within 10 blocks. The real case is likely to be worse than this as not all miners are mining at the 2% fee I assumed.
This is why you need a big buffer to pay PPS. The pool should look at alternative financing methods.

So the pool has been pretty low and I put some more in yesterday or the day before. I begin to lose track, I've been traveling.

Thanks fireduck - I moved off the pool as we were getting low as I feared payouts would be curtailed until a block was found. Hopefully we get lucky again and find a few shares in the coming day(s)!

Well, since you're committed to keeping this pool open, I'll point some of my personal hashrate your way too - just a few gigahash but hopefully it'll bump things up a bit  |

After lowering the requested difficulty from 128 to 64 my stale rate went up from ~0.5% to ~1%. Does this make any sense?
The stales are always "prevhash-stale". Are those stales payed? I'm wondering because paying stales would almost eat up my fee (1.5%).

After lowering the requested difficulty from 128 to 64 my stale rate went up from ~0.5% to ~1%. Does this make any sense? Halving the requested difficulty you find and submit twice the shares in the same time. So if you submitted X shares in the "stale time", now you're submitting 2X shares in the "stale time" (of course X and 2X aren't exact values: we're speaking of averages). But now every share is worth (about) a half too. The stales are always "prevhash-stale". Are those stales payed? Sure. You can see it in your account page (please click on your bitcoin address in the main page), looking at the btc column: even if a share is prevhash-stale, nonetheless it is payed. Obviously other types of rejected shares (for example duplicated shares) aren't paid - and you'd see 0.000000 in the btc column. I'm wondering because paying stales would almost eat up my fee (1.5%). Don't worry. The lower is your requested difficulty, the higher is the fee. So: if you lower the difficulty, the pool gains more, no matter what. |

Yes, but (1.5 nominal fee - 1.1 stales)% = 0.4% fee doesn't sound like it's sustainable for the pool.

Sorry, I see now that I didn't clearly answer your main question.
If you have just switched the difficulty, you can see a higher stale rate for a while: now you're submitting twice the shares (and so twice the stales) with regard to your history. Stales is a little number that can go up quickly, while total is a big number. So you can see your stale rate jump for a little while, but after a little time you should get back to your standard value (0.5%).
Example: my stale rate is 0.5%, give by stales/total: 50/10000. Now I go from 128 to 64 difficulty, and five blocks are found very quickly.
My stale rate is now (50+10+10+10+10+10)/(10000+500+300+400+300+500)=100/12000. But it won't last long.
