Sorry! I thought I was in the bitcoincard thread when I said that.

You successfully confused me to be in the bitcoincard thread too, when I read your post :-)

Guiminer has only one spot for a password, which is for connecting to bitcoind/p2pool/pool.
yes and i had the wrong password in the password field in guiminer.

this stopped me mining via P2Pool.My stats stopped on P2Pool it looked like i was mining but i was not getting credits arriving in my wallet, now i have changed it to the correct wallet password i am now seeing stats and credits in my wallet.

Thats what I am talking about. I am pretty sure you used that password for your wallet and which you put into Guiminer for more than just your wallet. Are you sure you only use it for your wallet?

I hope you all find this interesting: NPW 5.1 p2Pool - bad luck or flawed?

Let me know if I've made any egregious errors in how I've described how p2Pool works.

Great work!
Nice to see a guy calculate through this who actually knows what he is doing! :-)
I will send you my p2pool mining data. Only a few datapoints per day, but maybe it helps. Would raw logfiles from p2pool help you?

I'm the noob here  Grin you tell me, i am just saying i found out why it was not working, without the correct password in Guiminer it was not allowing bitcoin to work with Guiminer and i was not getting credited for P2pool.
With my wallet password in Guiminer password field it works.

Maybe your wallet password is the same as your bitcoind connect password written in the conf?
If so, change your pasword! Too easy to steal your bitcoin in that setup.

Miner don't need any connection to any wallet.
Guiminer has only one spot for a password, which is for connecting to bitcoind/p2pool/pool. p2pool doesn't need and have a connection password, though?

Nicely done, but there is NO explanation WHY it is 10% longer than it "should" Tongue
And I have absolutely no idea if it is even possible or how.
I have a idea, but unsure how to prove it.
In my case P2pool.info ALWAYS and sometimes even my local node shows more hash rate than I have on my miner.
Maybe it it all ok in pool itself, just numbers send/taken to analysis are screwd? By this magic 10% ?
hashrate by p2pool on your PC and on p2pool.info is a GUESS based on the shares submitted at that time. I've had it say I've got 40gh/s because I mined with 1500 diff shares and got 5-10 shares in quick succession.
Maybe this "guessing" is the troublemaker. Some missed comma in code or something and all calculations can be trashed.
IE it is calculating that diff 600 share need 270MH (numbers form the roof) but in fact it need only 250. This way pool "guessing" that pool HR is higher than it really is, so time to solve block is shorter. But in fact it takes longer because real HR is lower.
In "normal" pools where SD=1 error margin is much lower (higher accuracy), we have SD~600 and rounding numbers up/down can make statistic troubles.

Edit:
From my week graph:
Local rate = 132MH/s
Local rate reflected in shares = 164MH/s
So pool "guessing" that I have 20% more hash power than I really have.
If everyone have +10% on stats then "bad luck" problem is only a statistic myth. If more ppl have over +10% ... then everyone should mine there Tongue

Theoretically, possible.
But at the end of the day, miners don't care about numbers, rates, stats and graphs. They simply look into their wallet and compare the daily income to other pools and to mining calculators. It is there where 10% are missing (it seems).

I probably won't dig through the raw data, the graph you make out of it is great already! :-)
Didn't know your site before, very helpful! Thank you!

One question though:
Would it be possible to separate the graphs into individual images? For example, http://bitcoinx.com/charts/depth_mtgox.png contains all three MtGox orderbook graphs.

Why do I ask? I made myself a html file with several graphs from several places, so I have an overview at a glance. Of course I only have that html on my local computer, refreshing it a few times a day, and won't use it on any webpage or the like.

Thank you,

Ente

sorry but this request is too special. maybe you can crop it in php or js ?

Actually yes, it was pretty simple once I knew what to search for:

Code:
<div style="width: 1040px; height: 220px; overflow: hidden; position: relative;">
    <img src="http://bitcoinx.com/charts/depth_mtgox.png" style="position: absolute; left:0px; top:-500px;"/>

If this is not rushing, I don't know what is..
The dev(s) are not rushing this change and I'm just urging them to be more aggressive about it Smiley Because the change looks very useful.

My skeptizism boils down to: Who are you, in respect to p2pool? User, dev, guy who had forrestv on the phone an hour ago?
A user.

Thank you for your patience and explaining the situation! :-)

It's not being rushed[..]

Some very important optimization changes have been made! It could reduce the block orphan rate from current 5%-15% to <1% (ideally).

https://github.com/forrestv/p2pool/commits/master

Everyone, please go update NOW!

Devs, please force this upgrade by splitting the chain, people will not update voluntarily Sad

If this is not rushing, I don't know what is..


[..]we're losing money (>2%) NOW!

"Now"? If we are, we are since months now!

And yeah, it's all in the official p2pool git run by forrestv.

1832  Economy / Services / Re: [ANNOUNCE] TORwallet - anonymous mixing wallet service on: June 15, 2012, 11:28:08 AM
Using a big service with your own coins does not help. They can still link the inputs to outputs. Since we are using a pool of many people's coins, simply linking the input to output only links us to ourselves, but introduces clean coins into the mix and makes it even more difficult to trace our client's coins. The worst case is that someone tracing can determine you used our service, but mixing with other services increases our pool size and makes this much more difficult.
I fail to understand how it's different, send coins to Instawallet, withdraw coins half an hour later, you won't get the same coins since it's a shared wallet.
Repeat this step with a second shared wallet, in another country preferably => coins cleaned.
And all this without handing your coins to a onion service that could instantly disappear with all the users funds.


..same problem with anonymous surfing: Sure, you can use one regular proxy. You are then anonymous to outsiders. But not to the proxy people, and not to the guys with the rubber hose talking to the proxy people. All right, use two, three, many proxys in a row? It only costs more time and effort to de-anonymize you, thats all. Maybe less than one workday, with scary confidential emails from three letter agencies.
The real solution, of course, is TOR.

And yes, you still have to trust TORwallet to not do something fishy with the logs. I, personally, already trust them more than other services to tumble coins. I will eventually try it out, with small amounts.

edit:
or, see it as a tradeoff:
- Regular services (yohndonym, instawallet): You can be pretty sure they work (and not steal your stuff), and you can be pretty sure they will eventually break (court order, raided servers, rubberhose)
- itself anonymous services (TOR, TORwallet): You will never be sure they will not run, once they have xy Bitcoin collected, or will be a honeypot to begin with (90% TOR nodes from three letter agencies?), but at least it it technically possible for them to not give out data in any event

Not to be a dick and all.. But why is not forrestv announcing this? The (main? only?) developer, you know? I am somewhat careful with code from the Bitcoin universe, where wallets are involved and stuff. "Prattler" has a low postcount, shouts, makes large promises and makes it totally urgent with the possibility to lose (forked) Bitcoin if one is not to react immediately.

I am sure there is an easy explanation to this, but still my eyebrow stays raised until I hear more. Forrestv is logged in, too, actually.

Except it's forrestv's git ... so unless someone compromised it ...

Exactly. That's why I have a "raised eyebrow", and am not running around in circles, shouting and having foam on my mouth ;-)

But in this combination, I don't trust GIT (which I do not understand in every detail) enough without having more info.

Hallo zusammen,

es gab jetzt schon mehrere unauffällige Erwähnungen (Bitcoinwatch, Berliner Stammtisch Thread), aber das ist einfach zu cool um so wenig Aufmerksamkeit zu bekommen:

Ein Wochende, in Berlin, um andere Bitcoiner zu treffen und endlich zusammen all die ehrgeizigen Projekte zu stemmen!

http://bitcoin-hackathon.com
https://www.facebook.com/events/320236274729013/

Es haben sich jetzt schon viele, auch international bekannte Bitcoiner angemeldet!

Kommt alle nach Berlin! :-)

Bestimmt gibt es Möglichkeiten, einen Bitcoin-Dienst mit weniger RAM zum laufen zu kriegen. bitcoinj, bitcoinlib, eine Android-App, den original daemon optimieren, etc etc.
Bei keiner der Optionen sehe ich, dass man das mal so eben umsetzt. Wie viele Stunden sollte man einkalkulieren, bis es stabil läuft? 10 Stunden? Und wie teuer ist so eine Arbeitsstunde? Setzen wir mal einen Liebhaber-Stundenlohn von 2 Euro an, dann kannst du dir von den 20 Euro minimum Arbeitskosten, bei denen du keine Funktionsgarantie hast, gleich 1gb SD oder 1gb DDR1 oder 2gb DDR2 oder 4gb DDR3 Ram. Und du hast dann als Bonus mehr Ram.

Just wanted to point out that we've been operating a similar service for about 7 months now, with the focus on the security, we haven't had a single breach of security, our fees are around 2% (1%-3% randomized, to increase obscurity), and we have a solid user base and thousands of bitcoins going through every day, and volume means a lot in an anonymization service.
www.bitcoinfog.com (a freenet page with some information)
http://fogcore5n3ov3tui.onion (the address you must use, only accessible through Tor)
https://bitcointalk.org/index.php?topic=50037.0 (main discussion topic)

But hey, competition is always good for users, new features get developed faster Wink

Its not too kind to advertise ones own, basically identical service in a competitor's thread, you know?
It would be very kind, however, if said person offered a strategic alliance to exchange and mix coins, so both services and all users gain. ;-)
