How many rigs does realasicminer have? He is now at 4.3 Thps. Anyone know who this is? Or could it be BFL mining with the gear they're supposed to be shipping to customers? :-)
Its ASICMiner. They have some of their machines on bitminter for awhile while they are getting them setup. The plan I believe is to eventually move them to solo mining. So enjoy it while it lasts on Bitminter.

There is some confusion lately that having big miners in the pool means the smaller miners get paid less. That's not how it works. Your average payout is determined by your hashrate, the difficulty, and fees/donations. Other people's hashrate does not influence this at all.
If someone joins the pool with 10% of the hashrate, then the pool will be pulling in 10% more bitcoins, the new user will be doing 10% of the work, and the new user will get 10% of the payouts. You don't make more coins by mining in a big/small pool, and you don't make less money mining in a big/small pool.
But a higher pool hashrate reduces variance for everyone in the pool. That means you will have smaller variations than before in your daily payouts.

However, that depends on the order you send LP messages. If you order them higher hash rate first (like slush does) then those with a lower hash rate will get their LP that tiny bit later, if there are more higher hashing people on the pool. Of course this only means a small drop if it is the case. Also of course without the source code one can't verify how the pool prioritises responses to miners. But since you have to pay for the miner (it isn't free), I'd guess no one else has the source code

Ok, true, more users in the pool affects your work reject ratio, but the difference will be tiny. The BitMinter server orders long pollers by hashrate for getwork and getblocktemplate (GBT). For Stratum there is no ordering when pushing work (at least not yet). Currently at each block change work is pushed to 7000-8000 Stratum connections in 0.01-0.03 seconds. 8000-9000 long pollers (getwork/GBT) are notified in 1.5-1.8 seconds. A few more ASICs running Stratum won't really make any difference. Also of course without the source code one can't verify how the pool prioritises responses to miners. But since you have to pay for the miner (it isn't free), I'd guess no one else has the source code  Yes, the server software is closed source. And it wouldn't make much difference if it was open source, because you would never know if the source code I gave you is what I was running on the server. Not sure what you mean having to pay for the miner. There's no extra fee for using BitMinter client over other mining clients.

Why is bad luck strange? Wouldn't it be more strange if we only had good luck all the time?

how about the 2 blocks right before it 6m and 33m and the block after it took 11m. btw my 3 large samples dating from april 5 to now show no oddness. 1 ratio of btc blocks to nmc blocks earned was high one was low and one was close to perfect.

DrHaribo, may I ask this question without sounding accusing or implying anything because I'm honestly wondering:
How unlucky and for how long should it last before you would start to suspect anything? I don't have many months of experience but for the last 2-3 weeks I've only seen bad luck. Weeks are not a long time you will say, and bad luck can be just that, granted. But if the block/hashrate stayed like the past 2 weeks for, say, 2 more years, should we still not worry at all?
So basically because I'm biased and the pool has lived long before I joined, I was wondering when someone like you would start to worry.

The "luck" is best thought of as number of shares per round / difficulty. The average number of shares per round / difficulty for a number of rounds is Erlang distributed. So you can work this out for your self. 1. Get the following data from either the API or website: Accepted shares and difficulty 2. copy paste, and divide shares per round by difficulty for example (using last 20 rounds): Shares Difficulty shares/difficulty 723399.00 10076292.00 0.07179 106555.00 10076292.00 0.01057 13835959.00 10076292.00 1.37312 15105311.00 10076292.00 1.49909 1776241.00 10076292.00 0.17628 65975009.00 10076292.00 6.54755 5344984.00 10076292.00 0.53045 1070699.00 10076292.00 0.10626 18113727.00 10076292.00 1.79766 15491485.00 10076292.00 1.53742 34830739.00 10076292.00 3.45670 6035422.00 10076292.00 0.59897 10154632.00 10076292.00 1.00777 773437.00 10076292.00 0.07676 1857852.00 10076292.00 0.18438 7037050.00 10076292.00 0.69838 9280851.00 10076292.00 0.92106 20104601.00 10076292.00 1.99524 9749255.00 10076292.00 0.96754 9389599.00 10076292.00 0.93185 Average shares per round / difficulty = 1.22444
3. Once you have the average, you can use wolfram alpha to figure out how likely that result is. The command is: CDF[ErlangDistribution[numRounds, numRounds], average (sharesPerRound/D)] So for example, the data above would be: CDF[ErlangDistribution[20, 20], 1.22444]4. If the result is less than 0.975 or greater than 0.025, then you can consider the result within a 95% confidence interval and not very unusual. The result for the last two days is about 0.844, so the "luck" has not been unusual at all. If you want to find out the same result for any number of rounds, then just follow the steps above and you can work it out for yourself. Enjoy!

dude that is just wrong I can pick 5 good days out of the last 14. edit only 4 good days. maybe the server needs more balls/power.. but this is 14 days and I ballparked some math as I am tired april 25 17 blocks 13.6 would have been normal for 6.1Th hash and 8.97 mill diff. very good luck apr 26th 12 blocks 13.7 would have been normal for 6.2 Th hash and 8.97 mill diff .. slightly bad luck apr 27th 8 blocks 13 would have been normal for 5.8Th and 8.97 mill diff bad luck for this 3 day period we mined 37 blocks should have mined 40.3 about 91.8 percent or normal add in the nmc you push against most any other pool. apr 28th 10 blocks hash is 5.5th 12.32 normal below apr 29th 15 blocks hash is 5.5th 12.32 normal above apr 30th 6 blocks hash is 5.7th 11.36 normal way below difficulty changed to 10.07 mill 31 total for 3 36.08 normal for 6 days 68 mined 76.38 normal may 1 13 blocks hash is 5.9 11.76 is normal above may 2 10 blocks hash is 6.1 12.16 is normal below may3 7 blocks hash is 6.2 12.36 is normal below for 9 days 98 113.08 is normal may 4 10 blocks 15.5 under may 5 20 blocks 16.5 over may 6 11 blocks 16.6 under may 7 21 blocks 20.96 just over may 8 18 blocks 22 under 4 out of 14 good 2 close 7 bad 178 block mined out of 204.56 this is roughly 87 percent of normal . if the trend continues I would guess that the server struggles to keep up with the load. remember there is down time and this number ignores all down time. it also does not reflect the factor of 1.08 for name coins. so 1.08 x 178 = 192.24 divide by 204.56 = 93.9 percent and it still does not reflect any down time. so it is not as bad as it seems. but maybe more power is needed to handle higher volumes.

Yep, emails will go out. It's on the website in the lower right corner under "news", but I will add something that is easier to notice.
Not sure if I should spam 40 000 people with it. Maybe I should limit it to users who were active in the last months.
So far the message has gone out on twitter, facebook, google+ and bitcointalk. It's the twitter message that is on the bitminter.com website.
I'm one of the "set and forget" miners and I'm kind of disappointed. I knew this day would come... I guess it's time for me to run p2pool

If it's Re: the 1% fee, I think it was long time due, given the added value of BitMinter, the excellent uptime and reliability of the pool, etc. If it's Re: the notification method, I see nothing wrong in using the website to communicate (it has been pinned as a very visible banner for weeks), e-mail would only have been a plus IMHO. We just want some luck now  PS @organofcorti @philipma1957 thanks for you comments and analysis. I guess it would be very useful if there was some way to separate analysis for getwork, stratum and GBT. A statistical anomaly for one of the 3 protocols would be a great hint in case there was indeed a problem.

I really should do it perfectly correct but frankly it is a shit load of work. I am still satisfied the pool is running honestly. I am mining my 10Gh/s here and always mined with the doctor's pool since i found him last August 2012. As for the 1% fee causing a problem for a miner pleaseee . I have paid the Doctor 2 to 4 percent since August of 2012 why because he bothered to write an easy interface that to this day no one else has.

So basically because I'm biased and the pool has lived long before I joined, I was wondering when someone like you would start to worry.
Probability theory and statistics are not my fields of expertise. The smart thing for me then is to rely on people who are good with this. If people like organofcorti or Meni Rosenfeld, people who understand numbers, tell me that the numbers look strange, then I worry. When miners see bad luck and let their emotions run away with them, I ask organofcorti to perform a calm and thorough analysis of the data and present his findings so everyone can see what the situation really is. If you want to make the most coins, read his report when it's out. When it comes to money, math beats emotions every time. By the way, we just got 5 blocks in 22 minutes.  I'm one of the "set and forget" miners and I'm kind of disappointed. I knew this day would come... I guess it's time for me to run p2pool
I'm sorry you feel disappointed with the 1% fee. I was a bit worried about introducing a fee, but surprisingly I got mostly positive feedback. Last december a string of orphan blocks killed all the profits of the pool, back to the beginning. So the pool had zero profit. Server costs were not covered. What about lost income from the 1.5 man years of work I had put into this. As a skilled software developer and web security specialist, that's .. a few coins. BitMinter was a disaster. I couldn't keep working my ass off to help others make money, while I only had losses (server costs) myself. A minimum wage job would be a dream in comparison. So now we are the second cheapest pool, after P2pool. That's a much smaller pool with much more variance. If you think the luck swings on BitMinter are bad, then you'll be running away screaming. But if you set p2pool donation to zero, set up merged mining with automatic restart of namecoind when it locks up daily, and ensure you have good and fast connectivity to the most important nodes on the bitcoin peer-to-peer network to avoid orphans, and pray that other p2pool users have the same, then you should come out a little bit ahead on average. If you're lucky. I'm hoping that what BitMinter has to offer is worth more than that. I have paid the Doctor 2 to 4 percent since August of 2012 why because he bothered to write an easy interface that to this day no one else has.
Thanks, that is much appreciated!

if the trend continues I would guess that the server struggles to keep up with the load.
The funny thing is that the load on the mining server hasn't been lower in months. I guess some slow miners gave up and were replaced with ASIC miners. With var diff it's the number of workers and connections that matter, not the hashrate. Whether you have 1 Ghps or 1 Thps doesn't matter to the server - the load is the same.

New blocks are showing as stale, I'll get this changed to "processing" or something like that soon. Why are they like that for more than some seconds? Because while the mining server has a lighter load than usual, the payment processing system is lagging badly. I'll improve this soon. Apologies for the confusion it causes to show so many "stale" blocks, especially with all the fast blocks we had today it looked crazy.
