The script backups one or more virtual machines on one or more Xenserver hosts. The configuration of virtual machine to backup is read from an xml file.

With this scheduled task you can install all windows updates without user intervention. The reboot is automatic until all updates are installed.
Download the three files on the following gist. The files must be copied in the folder C:\WUA:

• C:\WUA\WUA_SearchDownloadInstall.vbs
• C:\WUA\WUA_SearchDownloadInstall.bat
• C:\WUA\WUA_SearchDownloadInstall.xml

After copying these three files open the task scheduler and import the WUA_SearchDownloadInstall.xml file. At the next reboot the task will start the update process and will reboot the pc many times until all updates are installed.
IMPORTANT: Remember to disable or delete the task when finished.

Hello, yesterday i replaced the touch screen to my Galaxy Grand 2. It has android version 4.3 and after replacing the touch screen all was working.
So, after replacing touch screen i decided to update android to version 4.4.2. After updating the phone didn’t boot anymore. It hangs on boot with the blue text on top of the display “RECOVERY BOOTING…..”.
The problem was the touch screen. Detaching the touch screen the phone boots correctly to android 4.4.2. (this touch screen had no duos logo, another touch screen with the duos logo works perfectly)
Now another problem, with android 4.4.2 insering the sim card the phone says: Emergency calls only. This is a problem with modem.bin image. It has to be updated with odin 3.07 using the PHONE button. You have to download the modem.bin for android 4.4. You can find it on the internet, for example from here:
http://www.mediafire.com/download/x4loxo3ax4bh21p/Modem+4.4.2.rar
After updating the modem.bin with odin 3.07 the network works correctly.
(Use odin 3.07 because newer versions have no PHONE button)
 

I have a Samsung Grand Neo Plus. That phone misses the brightness sensor but has the front facing camera.
Using Lux Lite (the free version) or Lux (the full version) application it’s possible to configure the front facing camera as brightness sensor.
After installing it, the application uses the light conditions captured from the front camera to change the phone brightness. I set the brightness update on unlocking.
Another useful thing is the possibility to increase the brightness shaking the phone. In Settings >> Brightness >> Shake to increase brightness. It works being in the lock screen.
If the brightness is too high or low it’s possible to customize the regulations opening the application, modifying the brightness and clicking on the chains symbol to link the ambient light values to the display brightness.
For my Grand Neo Plus I linked the following values:
