Will the "segwit1+empty_block_fix1" be released in binary .exe? Or do I have to figure out how to setup .python .twisted to update my node?
PS. If someone has broken bitmain APW3 psu's, I am interested to buy..

Couple Questions:
1. Should I transition to SEGWIT if not implementing it currently?
2. Is renting hashing power worth it?
3. Why are some nodes connecting, grabbing a share, and disconnecting directly after?
4. How did all of you get so awesome?
Thanks in advance

Perhaps one official p2pool.org node in Europe to reduce latency bring new miners 
Use any nearest node from the list: http://poolnode.info/There all nodes official
Hahahaha
For example if you mine at this node http://45.32.185.195:9332/static/ ( from http://poolnode.info/ ) you only loose time and money
Node Fee: 0%
Protocol Version: 1600
Do not see why to laugh.
Speak the voice of experience
I lost a lot of time and money in this node http://elizium.name/ when it was active and outdated
http://elizium.name/ IP=95.170.95.133. I do not see this IP in the list.
But in any case must be checked.
I found the wrong operating node: http://62.210.213.17:9332
On this node: "Pool rate: 539MH/s (0.0% DOA+orphan) Share difficulty: 1.00"
Currently pool rate - 5.89 PH/s.

Because it's a parallel p2pool share chain ( p2pool version 13 )

I do translation for the Russian-speaking forums. I do not understand this paragraph:
would it help if I changed it to, "reward will go to the blockfinder"? 3) Your address must be the one that finds the next block starting now. Contest ends once the next block is found from the timing of this post.
That is the address of the participant should find a block? Or enough to participate in the block search? February 26, 2017, 04:59:22 PM

I join a question:
Has anyone found a block with this patch installed to verify it works as intended?
February 26, 2017, 04:18:22 PM
I assume a p2pool restart is needed afterwards?
Yes. I do It so:
Code:
git clone -b segwit1+empty_block_fix1 https://github.com/veqtrus/p2pool.git p2pool-temp
Then stop the node and delete the contents of ~/p2pool/p2pool/ subdirectory.
And copy all from here ~/p2pool-temp/p2pool to here ~/p2pool/p2pool/
Then run the node.
All this only takes a few minutes.

For your convenience (yes, it is compatible): https://github.com/veqtrus/p2pool/tree/segwit1%2Bempty_block_fix1
Thanks.Not being familiar with CLI I wouldn't have the first clue how to add the patch 
Now it's easy to do:Code:
git clone -b segwit1+empty_block_fix1 https://github.com/veqtrus/p2pool.git

Good work, that explains it. You may also wish to decrease the time interval as well since transactions change so frequently. I noticed a long time ago when proxying to p2pool that stratum updates were few and far between. I suggest 60 seconds instead of 10 minutes... The stratum specification says it should be under 90 seconds IIRC.
Stratum updates should happen on average every 30 seconds due to new shares being found; not sure about transaction updates. February 26, 2017, 03:43:06 PM

I think I found what is the cause of empty blocks. When p2pool receives a newer block header it immediately attempts to mine on top of it until it receives the corresponding block template from bitcoind. This can take some time as currently p2pool fetches templates on fixed intervals (AFAIK). The relevant code can be found here.
Let's look at the empty block (00000000000000000201d592fcfcf59af02bdfe822123154a4a724ec7ffa0982) and the one before it (0000000000000000000e689d993b465aaa23e56e87d0f6c649de4b98830f789c). The time interval between them is exactly 1487923858-1487923258=600 seconds! This indicates that the p2pool node was still mining without the block template from bitcoind.
I made a patch so that p2pool tries to fetch a new block template as soon as empty work is detected and give up working on the new block header if it can't get the template.

This patch is compatible with SEGWIT patch?Veqtrus, please collect all your patches in one brunch.
