yey just 2 blocks in 1 minute Cheesy

wtf? shut the hell up Cheesy

p2pminers are unionized, if they hear you talking about luck they'll take the week off.
lol why should they Cheesy

We do not use the L word here and do not talk about it in any round about ways. Usually when someone does mention it, things go badly.

Yeah the problem there is that there are some people who actually believe that the text placed on this forum can negatively affect the pseudo-random distribution of bits coming out of a fixed non-random mathematical equation Tongue
Kano, stop spreading FUD. I have luck charms for sale and you're ruining my market.
how much per "luck charm" Cheesy

I'll sell you a luck charm for your soul. Bulk rates apply if you have more than one soul.

Hmm.  Methinks that rules out a lot of people here.

M

I mine at Kano's Pool because it pays the best and is completely transparent!  Come join me!

I'm running Win7 64bit with 12gb of RAM and a 3 core 3.0ghz processor and P2Pool is always losing connection to bitcoind. What can I do to keep bitcoin running properly?

edit I created a symbolic link to the Bitcoin folder in appdata and moved the blockchain stuff to a faster drive in my computer. I'll see if this helps.

I have linux VM w/2GB ram running two p2pools and 5 xCoind`s w/o any trouble Smiley
Try exclude bitcoin and p2pool directory form virus scanning.

Since moving the blockchain I haven't had any errors so far. I think it was caused by my c:\ drive being an old IDE drive I stuck in as a replacement when my SATA one failed a couple months ago.

How do you donate BTC and LTC into P2Pool development.  I couldn't find any wallet addresses anywhere?

Either run your node with the --give-author [percentage] flag or this: https://bitcointalk.org/index.php?topic=57027.0

Ye, I was surprised by growing v7 from thin air lol. Why we want to delay switch to v8? Forrestv found some  bad buggys?

Yes, there's a bug that Smoovius reported on the Litecoin P2Pool, which would also apply to the Bitcoin one. P2Pool's memory usage can grow without bound after a fork like this if you maintain connections to people mining on both forks. P2Pool is unable to forget about the children of the root node that connects the two forks, due to that operation simply not being implemented. (I assumed that one fork would always lose eventually, resulting in a linear chain whose last node can be forgotten about.)

Anyway, it's fixed in git, and after some more testing, I'll release v9 and the switchover will be triggered when v9 becomes popular. Restarting P2Pool after the switch would have been enough to fix this, but many people don't have something auto-restarting P2Pool if it crashes or even check up on it often.

The switchover happened on the Litecoin P2Pool about a week ago, and went flawlessly other than this issue.

Odd, I wasu sure that "final fork" will be automagically in 24hrs from version switch ("old" chain forgot).
Good that huge memory consumer was found.
In fact, I did not noticed that bug on my LTC node ;]

Well thanks to Smoovius for finding it and to you for fixing it.

What is the plan for ASIC's? Will it require a switchover as well? If it requires a switchover, why not do it now instead of waiting until ASIC's are already out and about?

I don't think ASICs will need any special support. P2Pool can provide getwork results fast enough for hundreds of GH/s (from a normal computer) and could be optimized for more. In addition, any timestamp rolling multiplies that.

What about mining on a remote node? It seems like ASICs could kill P2P Mining.

Any serious P2Pool user, one serious enough to have ASICs, should definitely have their own P2Pool node...

...With ASICs being 50x more efficient, the only people mining in the future, bar a very few exceptions, will all be running ASICs.

And anyone (everyone?) with an ASIC, having invested hundreds of dollars, will be a "serious miner" in my eyes...

Some people, such as myself, can't really afford the high bandwidth usage of running a node. That's the main reason I switched pools.
