When is this round going to end

Seeing as my nodes have had very bad luck the last couple of days (2.2hrs to share, 6 shares in the last 48 hours!) and my payout has dropped to under half what it was a day ago, I'm predicting a bunch of blocks in short succession!

Future mining is unaffected by past mining.
Thinking otherwise is called the Gambler's Falacy.
I added a BFL SC Single on to p2pool today ... I wonder if that will help

(P.S. I run /+64 but I don't put up the true share difficulty)

I am aware of that, just pointing out that my luck (in general, not just mining) always seems to be on the bad end of the scale. Maybe I'm just jinxed.

[daemondazz]

Maybe I'm just jinxed.

Told you, my payout is currently at about half the normal level due to the my bad luck in finding shares over the last couple of days and this is when we find 2 blocks in less than 2 hours.

There is no such thing as predetermined mining luck or misfortune
Though bad software or hardware doesn't help

Edit: yes 16 block apart - not too bad.

Edit2: see it was making up for your half payout by paying you twice

How far back does p2pool look at your work share to calculate your share in a solved block?

How far back does p2pool look at your work share to calculate your share in a solved block?

The length of the share chain is around 8640 shares, which with an average 30s share time, is 3 days.

What spec of machines are folks using for p2pool?  I'm thinking of setting it up myself, but not sure what machine to use.

I've got a Celeron 847 (dual core 1.1GHz) with 8GB RAM and a 64GB SDD.  Is that likely to be enough?  Probably running Windows Server 2008R2, so very little OS overhead.

That should be plenty.  The SSD will be the biggest help.

Problem isn't necessarily p2pool, its bitcoind. As long as it can produce work in .1 seconds you're good. For a couple microseconds it will use 100% cpu, and remember disk space as blockchain gets bigger.

Yeah, I think I might use a different SSD, something a little bigger.   The little Celeron 847 is pretty quick for what it is. 

[freshzive]

The celeron might not be enough. My latency on a 1.3ghz dual core atom (8gb ram, 120gb ssd)  was high enough to increase my orphan  and DOA rate pretty dramatically. The  again, the celeron should be slightly faster.

My getblocktemplate latency was around ~500ms with the Atom. Dropped to ~100ms running on my main i7.

[bitpop]

Idk the celerons, atoms and i5s I've used are trash

[dc81]

So looking at the two highest hash rate public nodes,
http://195.72.200.193:9332/ at ~230 GH/s and ~15 (!!) second latency has an efficiency of >105%
http://178.27.235.42:9332/ at ~150 GH/s and ~.25 second latency has an efficiency of ~100%

Even looking at ~3 GH/s nodes,
http://1.202.128.218:9332/ has ~2.5 second latency
http://88.190.31.3:9332/ has ~.1 second latency
Both are around ~101% efficient

I'm running p2pool/bitcoind/altcoinds/cgminer on an Intel Next Unit of Computing with a Celeron 847 @ 1.10GHz, 4GB RAM with 4x AsicMiner USB Eruptors. I had to move the blockchains (bitcoin, devcoin, namecoin, ixcoin) to an external USB hard drive (system drive is 32GB SSD). It took some tweaking, but my get work latency is ~0.2-0.3 and I see DOA of 1.5% and 101.5% efficiency. CPU load seems pretty low (~80-90% idle mostly). Seems fine to me. Biggest problem is that my share luck seems to be inversely proportional to p2pool's block luck.

[lavajumper]

I'm setting up a p2pool for an altcoin. Mining appears to work well, but I can't get the stat page to display any stats. The stat headings show up, but not the data. The graphs are working. I'm not a python guy, and I'm having a hard time figuring out where to start. There's no errors in the logs. Could someone give a suggestion where to start looking?

You have to wait a while for the chain to get long enough for some of the stats to work, so mine for a few hours first. A screenshot would be helpful.

[lavajumper]

Javascript is on.

I'm getting this:



And this:



The only data filled in is the graphs.

If I got to /web/tails or /web/head in my browser I get '[]' for both.

Is there an idiots guide to setting this up for another coin. I got the .math entries, but I'm thinking I'm missing something big.

You're using non-standard UI?
can you share node's address?
