BTW it's kinda a bummer the max share chain is only 3 days. The SPREAD is 3 blocks worth of work, so that would normally mean any share someone finds should get one or more payouts. Is the reason we have a max share chain length at all to prevent abuse? I'd think the share chain should expand as much as needed automatically to store SPREAD worth of payouts...
If you pay shares on every single block you have proportional payout (subject to pool hopping abuse), not PPLNS.

No. It's not 'noticed because someone is looking for it' (which is what I think you meant with your analogy?). It is noticed because the 95% confidence interval for income as a fraction of expected income is much wider for lower hashrates than for higher hashrates.
Yes, as a fraction of expected income but ask yourself why that even matters. If you expect to get 0.003 BTC and you get 0.002 BTC (or even in one instance 0 BTC for that matter) how is your life impacted in some major way? Of course it matters. It matters to people who are hobby miners who try to optimise their equipment. It's hard to optmise if you only see a share every few days. You're also assuming everyone is a hobby miner with no concern for profit. Just because someone can only afford a low hashrate miner doesn't mean they can treat the investment as a "hobby cost". Lots of countries are poorer than the US. Daily variance does not reduce your profit. People are constantly on here talking about how pools with significant fees are "better" for small miners. That is false. In fact they reduce profit. Even in the case of looking at mining as a "paycheck" most people getting actual paychecks get paid once a week or every two weeks. Looking at your earnings every single day and expecting them to be some nice flat number every single day is stupid and counterproductive.

You've never noticed that people using public p2pool nodes are far more likely to complain that they are getting no payouts, than that the payouts they are getting a smaller than they expected?
Yes I've noticed a lot of complaints. I'm suggesting to those people to chill out and have fun with it, not get so upset about things that don't really matter. I also see a lot of theorizing about how "bad" the variance is for small miners from people I suspect are not even themselves small hobby miners. They are either not miners at all or are larger miners who are making unnecessary noise saying things that don't make real sense when you dig into the practical reality of it. They should just stop. Don't get me wrong, if there were some way to flip a switch tomorrow and reduce variance for smaller miners I would suggest we do it, but there isn't. Mining is an exercise in tradeoffs. For hobby miners I suggest making tradeoffs in favor of having fun and helping the network rather than wanting to get a "steady paycheck" of a few dollars a day.

People can stare at numbers on a screen or lines on a chart all day long but at some point you have to relate those numbers and lines to reality, and when you do that shortfalls on hobby mining do not really matter.

Again, if the pool has a dry spell you are only losing payout on one share, which is really not that much in the way of coin. Bigger miners are losing out on many shares (if the p2pool doesn't get a block in three days). They have more to lose.
But if you really can't take the variance but still want to help p2pool, split off some of your hash rate to one or more of the bigger pools where you get (tiny, tiny) earnings on every few blocks. You'll get some small steady earnings with a nice boost when p2pool has enough luck to generate payouts.

Splitting hash is a good idea if you want to reduce variance but also help decentralization using p2pool or at least smaller pools. I set up a mining farm for a friend with some hash on p2pool and some on eligius. If there were a need to further reduce variance, I would add ghash. I would avoid the pools with fees as it is not necessary to pay fees for good pools in the current market.

Thinking 22+ GH/s should be sufficient for p2pool :-)
At 22 GH you will still have dry spells on p2pool. As I said, though, don't worry about it, you'll have big payoff days too. Look at it every week or two and you'll be happy with the results.

However variance as a fraction of expectation is much greater when hashrate is lower, which I think is what roy7 meant, and what is generally noticed by most miners.
Noticed, perhaps, if you are watching the pot boil. If you expect to make 50c/day and you make 0c/day, that looks like a big deal, but in reality your actual shortfall is still only 50c. Not going to hurt anybody. Someone with a somewhat larger rig who expects to make $1000/day and makes $0/day (certainly possible when p2pool has 4+ day rounds), that's a $1000 shortfall, and may or may not be a big deal, depending on your financial situation.

Incidentally, one way to prove that that actually do have mining hardware is wait for it... "proof-of-work"!
A hashing operation that wants to prove that they have the hash power you purchased, needs only to point it at a pool that you specify. You can host the Pool yourself (for example using P2Pool), or tell them to use one of your Bitcoin addresses while pointing the hasher at one of the more traditional pools.
This while hash-power is still concentrated in one place, people would notice if an attack is under-way because the hash power they are paying for would suddenly disappear.
Only if everybody does that. If only a few people do it they can fraudulently run on fractional reserve.

The variance on 2GH on p2pool will, sadly, be massive. You could farm from sha256 alt coins though. Or else you might want to use a normal pool. (The proxy pool project I want to port to sha256 but haven't had time.)
Roy7 is a bit math challenged. The variance in absolute terms (meaning the amount of actual coins you will be above or below expectation) will be smaller the smaller your hash rate. If you are a very small miner you will be getting very little output no matter what. If you want to help bitcoin and also have some fun with your mining, just treat your p2pool output as a fun raffle. Every once in a while (maybe once per week, possibly more or less often) you will get a nice payout. The rest of the time you will get nothing. Either way you won't make a lot. Just relax and have fun it with.

Given the lack of transparency with most if not all of these schemes you might as well (and should) assume they are fraudulent until and unless proven otherwise.
Do not send money to anyone for any reason unless trust has been demonstrated in a transparent and verifiable way. If people followed this simple rule, these so-called mining operations as currently structured would all disappear.

Hello, Anyone have tried replacing the fan with any other which are slient than the inbuilt one? The fan which comes with Ant is extreamly noise. So i wonder if i can put some silent fans from coolmaster on the both sides. All suggestion and comments are welcome.
"Silent" fans are mostly a scam, they just spin slower and move less air. That won't keep an ant miner at the recommended temperature; they already automatically control the fan speed. The best things you do reduce noise are: 1. Relocate the miner where you can't hear it. 2. Reduce ambient temperature.

how to use p2pool for antminer S1 ?
Easy. Set miner url to the IP of the p2pool node followed by 9332 (example: 1.2.3.4:9332) and set your username to your bitcoin address.

Any email sent tonight will be taken care of by midnight mountain time.
Email sent 18:47 mountain time for 5 shares with all requested information. Still no refund received.

I do open PDF's all the time, but seem to be spooked by this one due to the warnings.
It's more than just warnings. We know for a fact * that the very same zip file contained wallet-stealing malware. That makes the rest of the zip very suspicious as well. You are justified in being spooked. * Fact in the sense that someone claimed to disassemble it and posted the code. In theory that could be fake.

Opening the zip in an of itself shouldn't be a problem.
Correct (assuming it has been verified to be a valid zip without some hidden executable component), but he said he also opened a PDF file. That's dangerous.

Now what? Besides any wallets that a person may have stored on their computer, of which is not the case with me, luckily, can the malware perform any other tasks like sniff for keystrokes, passwords, etc.
Bruno your tone is sometimes to read online but if you are serious, my answer would be to never trust that computer again until after wiping it, and be extremely cautious with any "data" files stored there.

It's possible that there were accounts without bitcoin balances.
Although, I still don't trust anything Gox says.
Right. I just realized that. Reference my edited post above... But... then that would mean that 900,000 of the customers either 1) never deposited any BTC or 2) were smart enough to get it all out before the final goxxing. I wasn't that smart, and I'd find it hard to believe that 90% of users who ever had a balance actually got it out. On the other hand, I wouldn't be surprised that Gox would claim any registered account as a customer, even if it never had any deposit/trade activity. I stopped using the site last year and withdrew essentially all of my btc when they stopped paying USD and had other issues. Was a huge red flag to me.

The point I am trying to make is that if this a profitable business model, with difficulty going up every 10-12 days it will take long time to break even.
It all depends how fast you think the difficulty is going to go up and what you think the bitcoin price is going to do. No one can answer that for you.
