I recommend you change PMS (Pooled Mining Server) to some other acronym. PMS is also a popular term for Premenstrual Syndrome used all the time in U.S. popular culture.
lol, everybody who live with woman know term "PMS". But I never used this term for my service; everybody call it simply 'pool'. Although all ideas for better service name are welcome :-)

You might add a function for an automatic donation in %
You are not the first asking for this 'feature' (I'm surprised :-). So yes, plan to implement this soon. Also many thanks to people who sent me direct donations already, although there is not this feature on site yet!

Some stats that I gathered via the json interface: Blocks: 20 Difficulty: 12252.03471156 Mean shares per block: 15978.65 Std. deviation: 11854.889675889019 Std. deviation of mean: 2650.8339181048295 p: 0.1597754530320632
These blocks were created with the old difficulty, so it is not yet updated here. I was mainly interested in the relation between difficulty and mean shares/block, since ideally they should be equal. Of course, due to the small number of blocks, there will be differences. For the statistical significance of this difference, there is the probability p. Very small values such as 0.01 would indicate that something funny is going on, perhaps cheating. Below is the code I used. The calculation of p is not very accurate, as I assumed a normal distribution. More realistically it should be the Poisson interval distribution, but I am not sure how to apply a z-test in that case. Nevertheless, this might be of interest to someone. #!/usr/bin/env python
url = "http://mining.bitcoin.cz/stats/json/"
#from jsonrpc import ServiceProxy #s = ServiceProxy("http://user:passwd@yourip:8332/") #info = s.getinfo() #diff = ["difficulty"]
diff = 12252.03471156
import urllib, json
def mean(l): return sum(l) / len(l)
def sigma(l): m = mean(l) return mean(map(lambda x: (x - m)**2, l))**0.5
import math
# from http://www.codeproject.com/KB/recipes/IronPython_normal_prob.aspx def phi(x): # constants a1 = 0.254829592 a2 = -0.284496736 a3 = 1.421413741 a4 = -1.453152027 a5 = 1.061405429 p = 0.3275911
# Save the sign of x sign = 1 if x < 0: sign = -1 x = abs(x)/math.sqrt(2.0)
# A&S formula 7.1.26 t = 1.0/(1.0 + p*x) y = 1.0 - (((((a5*t + a4)*t) + a3)*t + a2)*t + a1)*t*math.exp(-x*x)
return 0.5*(1.0 + sign*y)
data = urllib.urlopen(url).read()
blocks = json.loads(data)['blocks']
# floats are better for mean/sigma shares = map(lambda x: float(blocks[x]['total_shares']), blocks.keys())
n = len(shares) stddev = sigma(shares) sm = stddev / n**0.5 m = mean(shares)
# 2-sided z-test (normal distribution) z = (diff - m) / sm p = 2*(1 - phi(abs(z)))
output = [["Blocks", n], ["Difficulty", diff], ["Mean shares per block", m], ["Std. deviation", stddev], ["Std. deviation of mean", sm], ["p", p], ]
width = max(map(lambda x: len(x[0]), output)) + 1
for i in output: print(i[0] + ":" + " "*(width - len(i[0])) + `i[1]`)

Thanks for your math! It looks correct for me (but I done exams from statistics "so-so" :-D). Hope more blocks in pool history will make p better. I will add 'bitcoin difficulty' to block history soon, so users will be able to check those numbers for long term.

Just to let you know on your front page it says Pooled Mining Server http://mining.bitcoin.cz/and the PMS letter is highlighted.

Also, I call everybody to public confirmation that you are receiving yours rewards. Thanks!
I received my first payout earlier today so it appears the system is working just fine.

Received 0.06 Bitcoins from the system on December 20th, matching with the number shown in my account at that time. With a computer as weak as mine, that's much better than the flat 0 I would probably get from running the official generator so I'm happy, heh.

Hello! Short time lurker, first time poster. Reading through this thread I actually only made an account to vouch for the service being provided by slush. I have been in this pool since doublec had to shut his pool down due to VPS issues. I have successfully received a payout at: 183mEngWCLc8CSjiu5XMDNWoXgjP336q5L Not a shill for slush, just a user enjoying the service he provides ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Please have faith that he is not scamming anybody!

I restarted service before few minutes because of some compatibility fixes for Diablo's miner. Please check your workers if they didn't crash during update and if so, please update to the latest version of your miner software. Main miners already solved those crashing issues.
Many thanks to RichardG and Delia for correcting and writing better texts for pool site. I will update it soon!
Please note that I'm leaving Internet for few days now. Few people from forum have phone contact to me and in case of pool problems, I can go online and fix it soon.
So, Merry Christmas and Happy Mining!

Tried cooperative mining last night, had a few issues: - Started my first worker, after an hour or so I had managed to send back two shares, things were looking good.
- Reading on the forum I found that if I am going to start another worker, I should register a new worker, so I did that, and then the shares I used to have went back to zero!
- Started up the workers anyways, and left them running all night
- Accumulated a couple more shares over night, but then this morning the worker segfaulted, and suddenly my shares are back to zero according to my profile
I like the idea of cooperative mining, but something doesn't seem right with how the statistics are gathered if I can easily loose things like this.
