1  Alternate cryptocurrencies / Altcoin Discussion / gui miner scrypt does not recognize graphic cards, any idea how to fix on: November 30, 2013, 09:31:52 AM

I shutdown my mining rig earlier this summer, and took out my graphic cards and uninstalled the ati catalyst driver.  Now I reinstalled the cards and drivers.  Catalyst and MSI's overclocker tool recognize the cards, but the guiminer does not see the cards, the drop down selections only show the CPU. 

Any idea what the problem is?

2  Other / CPU/GPU Bitcoin mining hardware / windows 7 power management setting question on: April 17, 2013, 07:42:57 AM

What is the correct power management setting for the HDD and other components?  Do I need to change the setting to never shutdown the HDD or monitors and such? 

I noticed that it took forever to update the blockchain when I started the bitcoin client and left the room, and noticed that when the monitor waked up, the blockchain download appeared to have stopped and restarted after a 10-20 seconds.

3  Economy / Service Discussion / Help with getting started with mtgox api request on: April 15, 2013, 02:13:19 AM

I want to create a very simple php based interface to display data from Mtgox api.  I don't like their trading interface, so I want to create a web page to arrange the displays to my liking. 

The link for the unofficial api documentation

As of now, I am stuck at the very first step of being able to retrieve data and display the data using the available example php code.  The code is unable to retrieve a very basic data dump.  Could someone give an working example to get me started.  I am trying to implement mtgox api version 2.  The only code that I modified to the standard code example are the path and the base definitions (highlighted in bold in the code below)

Thank you

function mtgox_query($path, array $req = array()) {
// API settings
$key 'my valid key';
$secret 'my secret code';
// generate a nonce as microtime, with as-string handling to avoid problems with 32bits systems
$mt explode(' 'microtime());
$req['nonce'] = $mt[1].substr($mt[0], 26);
// generate the POST data string
$post_data http_build_query($req'''&');
$prefix '';
if (substr($path02) == '2/') {
$prefix substr($path2)."\0";
// generate the extra headers
$headers = array(
'Rest-Key: '.$key,
'Rest-Sign: '.base64_encode(hash_hmac('sha512'$prefix.$post_database64_decode($secret), true)),
// our curl handle (initialize if required)
static $ch null;
if (is_null($ch)) {
$ch curl_init();
curl_setopt($chCURLOPT_USERAGENT'Mozilla/4.0 (compatible; MtGox PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
curl_setopt($chCURLOPT_URL''.$path); //Base URL
// run the query
$res curl_exec($ch);
if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch));
$dec json_decode($restrue);
if (!$dec) throw new Exception('Invalid data received, please make sure connection is working and requested API exists');
return $dec;
// example 1: get infos about the account, plus the list of rights we have access to
var_dump(mtgox_query('BTCUSD/money/ticker'));// PATH
// old api (get funds)
// trade example
// var_dump(mtgox_query('0/buyBTC.php', array('amount' => 1, 'price' => 15)));

I run this code on a PC with xampp installed.  The output error is

array(3) { ["result"]=> string(5) "error" ["error"]=> string(45) "Identification required to access private API" ["token"]=> string(29) "login_error_invalid_rest_sign" }
4  Economy / Trading Discussion / Mtgox verification queue issue on: April 10, 2013, 09:59:57 AM
I originally opened an account at Mtgox almost two years ago and deposited money through dwolla.  But now I am no longer able to withdraw by dwolla because I am not a verified account holder.

So I filled out the necessary info to get verified yesterday.  I was in the queue at ~15400 initially.  But I just checked back with the process and I am now moved further back in line at ~16200, WTH?

Do they have a secret express line that is not advertised? (half joking)

According to their timeline, it is iffy that they can manually verify 1600 accounts a day considering that they have been slow with support questions.


Another issue I just ran into is that all withdrawals are now halted because the account is in the verification status.  I can't even withdraw money or transfer out coins at all.  So by asking them to verify your ID, you basically can't withdraw at all, not even at the amount set for the unverified level.
