Capture full screen in muti-screens Windows XP by Qt

I've just want to put some small solution here, I've spend few hours to find out why same procedure works fine in Linux and Mac OS,but always returns only first screen image in Windows XP. This is recommended use:

QPixmap::grabWindow(QApplication::desktop()->winId());

And in windows XP it always capture only 1st screen, so this hack solution how same overloaded procedure works fine : 

QWidget *scr = QApplication::desktop();
WId w = scr->winId();
QPixmap pm = QPixmap::grabWindow(w,0,0,scr->width(), scr->height());
Just specify geometry of all screen and it works perfect.

Why Magento sucks?!

It's childish way to say system is too complicated, read the f**king manual, omg is this so hard?! So from perspective technical guy that have a lot of finished high loaded projects on the back, I want to explain my "sucky" point about it.  1) The thing that bothers me for last few weeks is news about Magento acquir...

Bounds.intersect is bad, mkay?!

I was trying to check when enemy ships are getting out of screen to destroy objects (optimization). First version Vector2 screenSize = new Vector3 (Screen.width, Screen.height, Mathf.Abs (Camera.main.transform.position.z)); Bounds screenBounds = new Bounds (new Vector2(0f,0f), screenSize); Debug.Log ("Ship " + ship.renderer.bounds + " Screen " + screenBounds); if (!ship.renderer.bounds.Intersects (screenBounds)) ship.Destroy (); So apparently this operation is taking significant time to check, end up replacing with this Vector3 screenPos = Camera.main.WorldToScreenPoint( ship.transform.position ); Vector3 screenSize = Camera.main.WorldToScreenPoint( ship.renderer.bounds.size); if (screenPos.x + screenSize.x < 0) ship.Destroy ();

Magento API + Java != Friends

Recently I've had a task to write small integration of Java to the Magento API, and meet a lot of troubles on the way. First of all Magento supports SOAP web-services that actually don't work well, I've found one solution http://code.google.com/p/magja I didn't tried because we spend much time trying to make them work with no result, so next was XML RPC based API that worked quite well on PHP examples, but caused more trubles. Login worked pretty well: XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl(); config.setServerURL(new URL("http://magento.dev/index.php/api/xmlrpc/")); XmlRpcClient client = new XmlRpcClient(); client.setConfig(config); Vector params = new Vector(); params.addElement( "defsan" ); params.addElement("123456"); String session = (String)client.execute( "login", params ); But other call's did worked, instead they show: Exception ...
