Looks like an attempt at an exploit.
Do you have everything updated to the latest (Bitcoin & P2Pool)?

As I was writing a PM to OP, I stumbled over my own theory.

Code:

Could you add something into the code for people to publish their version publicly?
I've got the public node list setup (http://nodes.p2pmine.com) and was wanting to sort the latest versions with the longest up-time.

Also, could you have a site that would also publish the most up-to-date version?

Actually, I guess in all essence the sourcecode is public and easily modifiable. So, who knows what version people are actually running...
Nevermind. _._

Assume that part of all the subsidies you have received cover the 0.5% default donation, get over it, and continue mining with p2pool, keeping the 0.5% donation enabled.

I also agree it should be added to the first post for people who don't read basic instructions for software they are running.

I agree that the default donation should be left on.

I also agree that the fact that donation is on by default should be in the first post of this thread, clearly stated so that it doesn't come as a surprise to anyone (it came as a surprise to me). The criticism doesn't revolve around the author being undeserving of the 0.5%, it pertains to people not being informed of the fact that they are donating. I agree this should be changed. The suggestions of DeathAndTaxes would be sufficient, I think.

1. I'm a cheapkate.
2. I'm lazy.

If the default donation was 0% I would never change it. A meager default donation (which can be turned off) in exchange for developing the awesome p2pool is an extremely fair request. About 40% of the network has already turned off the donation. I'm afraid if the default was off, the donations would drop considerably. At less than 1 btc per day, the donations are quite small for all the hard work developing p2pool.

Leave the default donation on.

b) Since when p2pool starts up it displays a lot of "house keeping" type messages having something like

Code:

2012-03-19 9:00:43 Donating 0.5% of gross revenue for the continued support and upkeep or p2pool. Thank you for your support

or

Code:

2012-03-19 9:00:43 You currently have donations disabled. p2pool is open source and provided at no cost however your financial contribution ensures continued support and upgrades. Please consider a manual donation or enable automatic donations with the command line argument --give-author .

I think this would be a really simple thing to implement. If someone doesn't read the --help and then doesn't read the startup messages, then they don't deserve to complain. Of course, I don't think they should complain about 0.5% to the author anyways.

I don't believe guiminer works properly w/ p2pool but I could be wrong. Still why use guiminer. It hasn't been updated in 6 months and likely never will.

Tested GuiMiner on LinuxCoin with my p2pool. Doesn't works.

I'm glad I convinced him to use p2pool (although oh-so-horrible variance and payout), convinced him that a shell isnt evil, and convinced him that a central node isnt more likely to crash than local nodes on every miner..
He still prefers a Gui and sticks to windows..

When I have it all set up with a central monitoring point for each miner I'll see if we switch to a a more recent (shell-) miner.. ;-)

I don't believe guiminer works properly w/ p2pool but I could be wrong. At one time other miners (except cgminer) had problems w/ p2pool but it looks like they have all been patched (except guiminer). Still why use guiminer? It hasn't been updated in 6 months and likely never will.

Yeah, that is pretty bad. To me, it looks like your miner is using your CPU and not your GPU. Is your miner reporting normal speeds?

Miner (Guiminer, poclbm) says between 280 and 290Mh/s constantly for hours now. It solved 330 diff-1 shares in the last hour, which seems about right. A 300Mh/s miner should solve 250 diff-1 shares per hour.. Miner says zero stales too..

Ente

EDIT:

what the..
After it ran at 10% the whole day, now it gets faster and faster! Its at 200Mh/s already! Just at it finished "verifying" the sharechain? Might that be the reason? It initially downloaded the sharechain in minutes, but took at least two days to "verify" each shareblock, one after another?

EDIT2:

It stabilized at 250Mh/s. All fine here now.
Strangely, the /graphs says it was right between 250 and 300Mh/s all day? hmm..

Thank you for your help and thoughts!

edit: silly smilies in quote

You have a pretty high local dead on arrival. I don't know what miner your using, but with cgminer recommended settings are 1 GPU thread (-g 1) and lowering your intensity a bit, that helps with that. The other part I don't really get is how you have such a high payout with such a low hashrate. According the http://p2pool.info/ you would need almost 5GH/s to get that.

----edit---
ugh, i see the smilies you mean now, i need to go and find how to turn those off...

I think noone here said that forrestv doesnt deserve these 0.5%. All that shouting lately seems to be just a misunderstanding? Some people said that the 0.5% set as default is taken to attack p2pool, therefore to think about making opt-in instead of opt-out. I agree with you, kjj, that it should stay as it is, as opt-out. People who dont manage to do that would find a ton more "problems" and nag with the same questions over and over again, so I agree to "screw em".
I just get annoyed by such random, unasked use of "fuck you". We are all on the same side, not?

I think it should be left opt-out. The reality is most people go the route of least resistance and it has been shown numerous times in everything from advertising to notifications if something is opt-in the opt-in rate is a tiny fraction of the didn't opt-out rate.

That being said to be above board two easy changes can be made:
a) The first post should clearly indicate there is an optional 0.5% donation to the author enabled by default. Put something there to explain that p2pool is free software (free as in free speech not free beer) and donations ensure continued support and upgrades from the author. Provide command line examples to modify the rate or disable it. Users should at least be notified up front of any potential fees.

b) Since when p2pool starts up it displays a lot of "house keeping" type messages having something like

Code:

2012-03-19 9:00:43 Donating 0.5% of gross revenue for the continued support and upkeep or p2pool. Thank you for your support

or

Code:

2012-03-19 9:00:43 You currently have donations disabled. p2pool is open source and provided at no cost however your financial contribution ensures continued support and upgrades. Please consider a manual donation or enable automatic donations with the command line argument --give-author .

is a good way for user to verify. If they somehow missed the first post seeing "you are donating" likely leads them to asking a question rather than mine for weeks and then (wrongly or not) feel ripped off.

Seems too easy to both leave it opt-in and remove any "grayness" real (or just perceived) from the issue.

Would "Fuck you" be less disappointing?

Forrest has spent hundreds of hours to make it possible for idiots like you to participate in a decentralized pool and still get regular payouts. And you say that he is exploiting people by having a default donation of half of one percent that can be changed by anyone that bothers to read the documentation provided?

Let me say it again. Fuck you. By creating and developing this incredible software, he is helping not just you, and not just all p2pool users, but the entire bitcoin community. You should do the decent thing and apologize for you ridiculous accusation.

..tempted to push the 'ignore button' on you, which would be the first time here..

Ente

Heh. Don't threaten, just do it. Won't bother me in the least.

But if you disagree with what I've said, rather than just thinking that I'm an ass, please say how and why. I've been wrong before, and I've admitted it, and even apologized a time or two. I don't think that'll happen this time, but maybe I actually was out of line.

But so far, Nim has made an outlandish and hurtful accusation against someone that has done more good for this community than probably 99% of us ever will. However harsh and rude my delivery, I think my point still stands.

please calm down a little...

-f fee is a percentage which will be kept by your bitcoind (default = 0)
--give-author is a percentage which will be sent to forrestv (default=0.5) and he really deserves it.

a simple run_pypool.py --help says:
--give-author DONATION_PERCENTAGE
donate this percentage of work to author of p2pool
(default: 0.5)

are there really people which don't do --help before they start a command line program?
