Wow! My miner found a block. Number 285163. A first for me.

Hi guys, thx for all the help so far. I have the proxy running but I get all rejects. Any Idea what I'm doing wrong?

Also If this is the wrong thread for help on this just say so and I'll bugger off.


C:\Mining\Mining_Proxy>mining_proxy -o nobl.poolerino.com -p 3344

Are you using the proxy from Slush's pool for scrypt based mining? With what hardware? I assume a GPU. I use ASICs for Slush with that proxy, my server has an ATI GPU and digs for doggie coins with cgminer. I'm not so sure that proxy you are using works with scrypt coins.

Yes it is Scrypt. I came to that same conclusion and have been looking for an alternative proxy. Looking into bfgminer right now.

I want to thank all you guys for your help and not bashing a n00b for my ignorance. You all seem like a great bunch, wish I had started BTC when I had the chance rather than losing my nut folding back then.

EDIT:  GOT IT!!!!

For anyone that this comes up in a search this is the stratum proxy for scrypt branch.

So 37% day luck np happens, 70% week luck yeah hmm.... and 91% month.... we sure something isn't wrong?  Might have to switch soonish myself but rather support spreading out hash power.

I'm never sure, but then people jump on me and say I'm a conspiracy theorist. I dunno, my opinion is our luck will improve once the database issues are resolved, just like last time it choked when we were getting close to 900TH/S. BUT, nobody wants to even consider the possibility that it's an issue backstage on the pool, which honestly is what appears to be happening. I love that "IT guy" mentality where anyone exploring potential explanations for what looks to be a pattern of "luck" is labeled as an idiot.

Wow! My miner found a block. Number 285163. A first for me.

Mine found 2 a couple days ago throughout a single day and my rig is microscopic in comparison to what I see out there. Is that equivalent lightning striking twice?

How do you check to see if your miner was the one that found a block?

I dunno, seems very funky.  just look at when everything is going smooth how quickly the confirmations for blocks found go....but when there is a glitch, the blocks take forever to get confirmations.  one block lasts 23 hours to confirm.  how many "website under service" messages have we seen today ?  all points to issues behind the scenes.  I think during bad luck collective hashing power should be pointed to BTCGuild ...LoL.  those guys find blocks left and right...never a sad 30% dry spell for so many days.  in the past  7 days or so our month luck dropped big time.  What the feezy ?

I'm not sure who you talk to, but if you look at the BTCguild thread, You'll see that they are all commenting on a bad luck streak as well.

30% worth i think not.   don't get me wrong...like slush pool...just hate this "bad luck" streak.  i paid too much to get jalapeno paydays.

I don't think anyone sensible would label someone "an idiot" just for looking at 'potential explanations for what looks to be a pattern of "luck" '. What often does get one's goat is when the potential explanations are so wrong headed that they just cloud the issue.

To work out if slush's pool's "luck" is unusual or not:

1. Get an average of difficulty 1 equivalent accepted shares / expected shares (mining difficulty for each block) for the last  "n" blocks.
2. Using the Erlang distribution, calculate the CDF using x = the average you calculated, k and lambda both = number of blocks.

You can use Wolfram Alpha if you don't have access to statistical software. Here's an example using a 10 block average average accepted/expected of 1.1:

http://www.wolframalpha.com/input/?i=erlang+distribution+Pr%28x+%3C%3D+1.1%29+%2C+k%3D10%2C+lambda%3D10

In terms of bad luck, if the answer is > 0.99 then that is pretty bad and would happen only once in one hundred reruns of k blocks. Likewise, and answer of 0.9999 would happen only once in ten thousand reruns of k blocks. If you'd averaged the last one hundred blocks and you got 0.9999, there would be good grounds to think something funky is going on. Otherwise, maybe not.

Give it a try and report back, and do ask questions if I haven't been clear.

Doing this is the only way anyone will take your concerns about 'bad luck' seriously.

seriously smart stuffs

seriously smart stuffs

I'm not really interested in kudos, I'm just keen for someone to try it and report back. I'm hoping that if a few regular posters learn how to do this it will help keep freak outs to a minimum.

Give it a try, Scyntech. If there's anything you didn't understand I'll explain it again. Anyone should be able to do this just by following the steps and using wolframalpha, but only if I explained it properly.

Organofcorti,

you do realize that to many the formula you speak of, and the terms you use are a foreign language right ?   (me included)  I took a look at it, but quickly turned away because it reminds me of something I would need a TI-83 calculator for =)

[necro_nemesis]

Didn't we just recently calculate how many gigawatts to expect from our flux capacitor?  We've had some luck today.  Just happens to be bad.  Tomorrow is another day.

OK, thanks for the feedback. Here's a simplified version:

1. Got to http://mining.bitcoin.cz/stats/
2. Add up all the numbers in the "Total shares" column.
3. Follow each link under "Block #" to find the difficulty at which each block was solved. (For orphaned blocks, assume the same as the last difficulty). Add up all the difficulties from each block.
4. Divide the result of step 2 by the result of step 3. Call this number "X"
5. Go to http://www.wolframalpha.com/
6. In the text box, enter the following, substituting your value for X:

erlang distribution Pr(x <= X) , k=20, lambda=20



So if you calculated X as 1.1, you'd enter:

erlang distribution Pr(x <= 1.1) , k=20, lambda=20


We use  k=20 and lambda=20 since there are twenty blocks on the basic stats page. If you were to use one hundred blocks, change the values to k=100 and lambda=100.


I think if you follow that step by step you should be fine. After that you just need to understand the results, but I'll help you with that once you get this part done.

yes, you are correct.  Now the only issue is how do we power that flux...plutonium is not readily available at our local Costco---you wouldn't happen to have a flyer in your pocket with the information as to when lightening will strike....would ya ?   =)

Nice job, organofcorti.   Much appreciated.
