1  Other / Off-topic / Quantum locking with a superconductor [CRAZY] on: November 18, 2012, 02:52:00 PM
Hi,

I Just got my mind blown away: http://www.ted.com/talks/boaz_almog_levitates_a_superconductor.html


TL;DW:
Quantum locking is a way of storing magnetic energy in a superconductor. This force is so huge, 2mm dish of the superconductor material can carry i1000 kilgram. Seriously cool.

2  Economy / Trading Discussion / Tip: accepting paypal more safely! on: October 20, 2012, 01:32:03 PM
Hi,

It seems that a lot of people are having problems with chargebacks on paypal.
In most cases you will lose the dispute and the scammer will win.

Golden tip:
1. Accept the payment as GOODS. (Not as gift or anything else, ask them to pay you as if they bought a good).
2. Make them go to the payment page and make them click the  "confirm receipt" button.

-> So the buyer says that he has received his item.

When the user/scammer opens a dispute you can simply bring up that they have clicked the "confirm receipt" button and that they have received their goods.

PS: They can bring up a dispute under the catergory "item is not as described" but you'll have to prove them otherwise then.
3  Economy / Trading Discussion / Crossing borders: with a lot of money? on: October 19, 2012, 09:01:21 PM
Hi,

I've been reading upon crossing the borders with money lately.
I'm trying to inform myself about the laws and regulations about the transport of money.

From what I've read, there is a maximum of 10,000  that you can transport over the borders WITHOUT registering it first.
(This is a regulations withing Europe)

I understand that in some way this is to prevent illicit activities etc, but it's hard to believe (for me) that you can't transport your own fucking money without telling the government.

Does anyone have more input on this subject (laws, regulations?)

4  Economy / Trading Discussion / Implementing bitcoin: retrieving the value? on: October 13, 2012, 10:42:53 AM
Hello,

I would like your input on this subject.

If you were to sell goods and accept bitcoins for it, what would be the best way to retrieve the optimal value $/bitcoin?

MtGox is trading at (Weighted Avg:) $12.03129
While others like FastCash4Bitcoins is buying at $11.46

I was thinking of storing the weighted avg into a database (each six hour period) for a week long, and calculate a stable price from that to accept bitcoins with.

6  Bitcoin / Development & Technical Discussion / Loadbalancing a pool? on: July 07, 2012, 07:37:07 AM
Hi,
So I am currently running a pool, and I noticed that the CPU-usage is pretty high (shit hitting the fan 360%) under a load > 20GH/s.
I came to the asssumption that they must use load-balancing to spread the miners over multiple hosts.

1. Is it correct, that big pools use loadbalancing?

7  Bitcoin / Mining support / Ufasoft Miner - Proxy support? on: June 15, 2012, 03:34:18 PM
Hi,
I am trying to get the proxy function of ufasoft to working but I am Huh
I set up CCProxy to test it out on my local machine, and that's working out great.
The miner successfully connects to the proxy (CCProxy says it connected) and when I get back to the miner, it gives me the 403 forbidden error code?
Has anyone expermintated with these functions?

SOLVED!
I'm retarded, I entered in the wrong password, explains the whole forbidden access.
8  Bitcoin / Bitcoin Technical Support / Pushpoold MySQL Tables & Columns Query! SQL Template on: July 23, 2011, 10:31:39 AM
This is the sql file if you're only going to run the BACK-END (pushpool) of a pool, you don't need this one i you're going to install a front-end like MiningFarm.

I haven't found ANY 'sql' template for it so here are the queries to get the database working:
I already added one worker: with the username 'test and password 'test'.
Save it as: 'somethingyouwant.sql' and then import it in your database!
Make sure to start with a clean/empty database!
Code:

CREATE TABLE IF NOT EXISTS `pool_worker` (

INSERT INTO `pool_worker` (`username`, `password`) VALUES
('test', 'test');



CREATE TABLE IF NOT EXISTS `shares` (
  `id` bigint(30) NOT NULL auto_increment,
  `time` int(4) NOT NULL,
  `rem_host` varchar(255) NOT NULL,
  `username` varchar(120) NOT NULL,
  `our_result` enum('Y','N') NOT NULL,

  `reason` varchar(50) default NULL,
  `solution` varchar(257) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=344576 ;
Corrections by: dikidera & Viceroy.


This SQL dump is also a fix to the following error:
Code:
Listening on host :: port 8342
Listening on host :: port 8347
Listening on host :: port 8344
Listening on host 127.0.0.1 port 8338
initialized
mysql sharelog failed at execute
shutting down
Use the above SQL template to fix the above error!

Donations are welcome!

9  Other / Beginners & Help / [FIXED!] I need some help with pushpoold! [fails to start up] on: July 22, 2011, 07:36:52 PM
Fixed, these were all mistakes by the cause of typos. I used my DNS (the VPS) instead of the IP. I also used my domain as remote host of the MySQL server instead of the IP! So don't use domain or DNS's like:
(www.urdomain.com or www.urdns.no-ip.org) to point to the servers, only use IP's.

A tip to all: make sure you check everything is correct, servers match, username of bitcoin and mysql match, passwords match with the correct usernames!

Whenever I start up pushpool( # ./pushpoold -E -F )
I get the following output:
Code:
# ./pushpoold -E -F
Listening on host :: port 8342
Listening on host :: port 8347
Listening on host :: port 8344
Listening on host 127.0.0.1 port 8338
#
As you can see, it doesn't say 'initialized' or anything and it stops the server.

My remote server:


My MySQL tables:


My MySQL columns:



My server.json
Code:

{
   # network ports
   "listen" : [
      # binary protocol (default), port 8342

   },

   #uncoment this when you want to use memcached (Recommended for
   # cache settings
   "memcached" : {
      "servers" : [
         { "host" : "127.0.0.1", "port" : 11211 }
      ]
   },

   "pid" : "/tmp/pushpoold.pid",

   # overrides local hostname detection
   "forcehost" : "localhost.localdomain",

   "log.requests" : "/tmp/request.log",
   "log.shares" : "/tmp/shares.log",

   # the server assumes longpolling (w/ SIGUSR1 called for each blk)
   "longpoll.disable" : false,

   # length of time to cache username/password credentials, in seconds
   "auth.cred_cache.expire" : 75,

   # RPC settings
   #Bitcoind Protocal settings
   #Host were bitcoind can be found on the network
   "rpc.url" : "http://127.0.0.1:8332/",
   #Username & password to connect to bitcoind
   "rpc.user" : "correctusername",
   "rpc.pass" : "correctpassword",

   # rewrite returned 'target' to difficulty-1?
   "rpc.target.rewrite" : true
}

Edit one: Ok it seemt that my server.json host was wrong, I fixed it.
Edit two: The passwords of server.json and bitcoin.conf didn't matched, I fixed it.
Edit three: Okay, these were all mistakes by the cause of typos. I used my DNS (the VPS) instead of the IP. I also used my domain as remote host of the MySQL server instead of the IP!
