single chip 100Mhash/s?

What about evolving the hardware to do the hashing rather than writing it as straight VHDL?

I had a good idea about using hadoop clusters to run the fitness tests for the evolutionary algorithm testing.

For those who have no clue what i am talking about, read the article about the professors that got an fpga to recognize the difference between two tones with way less than 100 gates and no CLK.

I always had a thought that evolving the circuits would be a way to find really fast ways of "cracking" various hashing algorithms, as well as making really tiny encoders and decoders for various projects.

Anyhow, i enjoyed this thread.

on windows you can just make a shortcut... I know guiminer is nice, but it does drop performance a bit, no idea why.

Cool!

Does slush not have the "pay transaction fees" set on the server side? deepbit's payouts are fast because the fees you're paying are used to pay out transactions, just check out the speed of payout!


Anyhow i am using my own pool right now so i withdrew my deepbit BTC.

Starting a pool is a PITA, because everyone wants to see BTC, especially new users, and if the pool is brand new, you won't get paid until a block hits, and that could be weeks. How do you get around this? I've thought about bringing up every CPU i have access too to mine on other pools to get BTC together to fund payouts of miners who think they should get paid for existing.

Even if you reject packets at your router the DDoS still clogs your incoming bandwidth. It's Denial Of Service - an easy way to deny service is to overload your proposed authentication server, just pass tens of thousands of spurious requests from spoofed IPs and it bogs down, denying service to your users who actually CAN authenticate. One of the only ways to mitigate DDoS today is to have the ISP kill the connections from their gateway - and you have to be a decent size to manage that.

I can actually think of a few ways that cost a bit of money per hour to run that could nearly completely remove DDoS attacks from the pools and front ends specifically, but i'll keep those to myself until someone offers a BTC bounty, since i'm technically in the business of selling such novel solutions.

Xenland - you ever need some quick security advice you know where to find me.

Nothing, i get a blank area where the panel normally is, but the rest of the page loads fine (the template.) I have admin set on the account. the reason i updated is you said you fixed some things and security.

is v2 going to allow seamless upgrade from v1?

I tried to use the git version of adminPanel with my existing install (not latest git) - it doesn't show anything... the old adminPanel didn't do anything.

How do i reset a user's password?

Can i go into the sql database and add shares into a table to make up for the fact that i had to delete the user's duplicate entries?

You know there's winners abound when the very idea that people should be civil on a forum leads to trolling in the very thread it is brought up in.

The internet is ruined forever. 

pushpool was not putting anything in the database, just reading from it. Therefore every other piece of software that relied on the shares table to be updated by pushpoold was not calculating the hashrate, or activity.

Picking one part of my statement that is incorrect and lambasting it without acknowledging the real problem is called the strawman fallacy.

I got it working (there was a bug somewhere in the pushpoold code, haven't diffed everything to figure out where yet) - and i will write a guide that uses the git snapshot i have as a base.

It just took 12 hours on my part and a lot of "works for everyone else!!!!!!111" from others.

I'm still glad the software exists, though.

most likely. and the owner is AFK (he mentioned this might happen and apologized)

for those hitting my errors earlier:

use these command to pull the latest source for pushpool

git clone https://github.com/jgarzik/pushpool.git
cd pushpool
./autogen.sh
./configure
make
sudo make install

setup your server.json properly, make sure you add
to the "database" section.

start pushpoold. handle your business.

*autogen.sh fails on EC2 ubuntu natty narwhal, you have to to get aclocal!

don't use crossfire. SLI is for video not GPGPU. i may be wrong but setting up separate threads for each GPU may be your best bet.

you can do what you want with cpu miners but not gpu. i can't even watch videos on the internet or my computer while i am mining because i underclock my VRAM and overclock the GPU.

with 3 fast cards, you will pull nearly a GH/s when you are mining, so i wouldn't worry about a couple of hours a day where you shut them down for some gaming.

guiminer/poclbm try these settings -a 5 -w256 BFI_INT AGGRESSION=19 -f 0 VECTORS see if you don't start getting more share submits. I get 105+ an hour with my single 5850!

Underclock your ram to 300Mhz, or 900mhz. try setting AGGRESSION to 13, as well. and -f 1. futz around and tweak till your happy with your share output. 

don't use the patch i typed up there it doesn't work.

pushpulld isn't updating anything in the mysql database, such as shares, active column in the pool_worker table, hashrate, etc. I haven't gone through everything but as far as i can tell it's not doing any updates of the tables. Any way to debug this?

hey you updated the git repo while i was making a patch:

http://paste.ubuntu.com/624849/

or

in register.php

This makes it so your pin can start with zero. or 2 zeros. or 3. this affected 2 out of three people on my new pool already :-p

the pin cannot start with 0. if you try it throws invalid pin. probably because whatever command php uses to determine the length cuts leading zeros.
bug just cost me a pool worker :-(

in register.php (onyl one i looked at) look for this section

change to:

look for:

change the block under it to read:


verified myself this time. 

pushpool is not setting mysql pool_worker "active" and hashrate. pushpool is working, because it accepts the login i gave it and throws client errors if i use anything else.
Pushpool is also not updated the "shares" table with any data, it says it's an empty set.
Do i need to write the logic to set these, or should pushpoold be doing this itself? Please advise! :-D

edit: /tmp/shares.log is full of stuff:
So obviously something is going wrong somewhere in the database calls. I'd like to know if i screwed something up or if there's something i can help patch. I know it is a weekend, though, so i'll just grin and bear it for now.

edit: my miner has been running ~300MH/s for hours now, and has submitted nearly a thousand shares (and they were accepted) - but this isn't reflected anywhere in the database. Is this a privilege setting or something?


Actually it resolved itself, bitcoind had to run for about 20 minutes before it finally stopped giving upstream RPC errors and connection lost in the client.



Stopped using gentoo and switched to ubuntu. It has something to do with ipv6, although on gentoo i changed USE="-ipv6 ipv4" and did emerge -DN @world and it did not fix it.
edit to ^: It's a gentoo issue 90% and the code in pushpool 10% because of the way that it gets a socket. I am not a  C programmer. I cannot patch this while ensuring it works for everyone.

Thanks to the developers for making something like this that is free and works at all. I couldn't have done it, that's for sure.

Right, sc.pool_worker is sort of working as intended, as my worker can log in with genewitch.1 and x as the password. But you see how the active and hashrate aren't set? What sets those? pushpool?
Do i have to code that logic myself?

and shares is empty, is pushpool supposed to populate this? the reason i ask is i can go pester the pushpool developers :-)

they are, i called it sc and a user called pushpool was granted all permissions on it. Both simplecoin and pushpool use 'pushpool'@'localhost' as the database login, and i know pushpool can see the database because it allows my worker to login via -u genewitch.1 --pass=x.
what actually has the accounting, pushpool? Maybe i can dig through your PHP to see where the accounting database calls are and try the queries in a mysql prompt to see if there are the correct values in there. If you need any of my json or config files i can provide them.

Thanks for helping me, by the way. I'm setting this up for #xkcd on foonetic. :-)

Edit: hey, am i supposed to add anything to pushpool to take care of accounting? like add sql commands somewhere or something? Or does simplecoin use logs to determine shares and activity and set the mysql stuff itself? I know all the frontend (for payments) is NOT handled by pushpool stock install, so maybe i missed a step where i move a config file from simplecoin to somewhere else. I did run mysql sc
