As a follow up to my last post, here's a better way of judging luck:



the boxplots show the median, quartiles and outliers. The median (the line through the middle of the box) should be ln(2). As you can see, there is significant variation - but not a great deal more variation recently than in previous times.

Looks like new chapter on NPW about P2Pool is comming Smiley

I'm flat out like a lizard drinking atm so if I can make some time for it, sure. But I get a feeling that everytime theres a new p2Pool miner, or new data, someone's going to question whether there's some new problem with the luck. Responding to the same sort of issues every few months is a bit disheartening. It's a Sisyphean task.

Just finished a multivariate Augemented Dickey Fuller test on the p2Pool data shares per round data since Novemeber last year, to find if a trend has actually occurred.

p value for trend occurring: 0.96
p value for drift occurring: 0.99
p value for no trend or drift in data: 0.019

So (and check this out, kano Wink) there has been no trend in the data since Novemeber last year.

Why does it look like there has been some kind of cyclical trend? This is probably due to the method used to illustrate "luck". Any interpretation is likely to vary from actuality in some way, and I recommend you don't use luck charts in general for any important decision about mining.

I'll try to post boxplots and smoothing spline results later.

Ah well - it just looked like it - but I guess, as we all know, maths often proves something isn't how it looks Cheesy

I know. Everytime I learn something new in probability and statistics I start with an intuitition of what it's about and how it works. I'm almost always wrong.

I know it's bad luck and all, but there has been 5 blocks found in the past week (should have been 11-14).

It's possible to automate it. Don't know if p2Pool.info could host it though.

i've officially made a run for the hillz

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

We need more power. Pool have to be over 600GH to have chance to make over 3 blocks per day and pay like it should.
NOW is best time to join p2pool ;]

Yeah, but who gonna pay for extra 300Gh/s of GPU hashpower? As we know, FPGA are useless on p2pool, and GPU miners are leaving slowely, moving to newer machines. P2pool has to change its strategy or it will vanish.

Bullshit: the last block I found on p2pool was with a Spartan6, they work perfectly on p2pool. Only BFL FPGAs are useless on p2pool

and GPU miners are leaving slowely, moving to newer machines. P2pool has to change its strategy or it will vanish.

If/When I get my Avalon(s) I'll put them on p2pool...

figures that like 3 hrs after i switch pools i get a block

guess it's not so bad tho cause of the 1/2 transaction fee bonus

not quite true, u can even use BFL FPGA's with p2pool if you use cgminer in combination with --bfl-range

Only trouble witch p2pool have devices that cant handle reset work messages and/or cant return nonces found in moment that they found them.
BFLs and some FPGAs returning results from work only when they do full nonce, with in case of p2pool is 50% chance to return work after longpool and all of them are DOA instantly.
GPUs and all "good" devices not have that issues - they return work instantly and asking for new one when hit by longpool/work reset.
Crucial is to make nonce as soon as possible, so changing threads (work units that are calculated in same time) to 1 on any device can actually make better efficiency (less rejects and more full nonces) even if hash rate is bit lower.

--bfl-range does not work with singles, but only with minirigs, if I remember correctly.

i think a few Day's with this "good" L*, the people goes away.

I provide a 1000Mbit+ Torrent-Seedbox in FR and a 500Mbit Box in NL for orginal Blockchain Bootstrap.dat download. and also for Armoryclient Torrent

Minirigs only, yes, and the first generation MRs didn't even support it.

On the other hand, it will be totally irrelevant with ASIC hardware since it hashes so fast there is no need to cut work up into smaller chunks.

Any way to get a more in-depth statistical analysis automated enough to host it somewhere like p2pool.info?

It's possible to automate it. Don't know if p2Pool.info could host it though.

If someone else wants to develop it, I would be happy to host it on p2pool.info.

The easiest way to incorporate it into p2pool.info would be for it to be entirely client side (running in the browser, i.e. written in javascript).  Maybe using something like D3.js to draw the graphs.  As a reminder (it's posted somewhere else in this thread but hard to find), all of the data that p2pool.info has about blocks and round lengths, etc, are available in JSON from here:

http://p2pool.info/blocks?all=true

If someone does this, feel free to message me and I'll help get it on the site.  Or if someone wants to develop this and host it elsewhere, I'm also happy to link to it from p2pool.info so that people will find it more easily.  Just let me know what you prefer.
