Installing Ubuntu on VirtualBox

I have a Windows 8 machine on which I will be installing Ubuntu 14.04 inside Oracle VM VirtualBox. First download VirtualBox and install it. For this example I am using 4.3.12. Download the image file for Ubuntu.

Once you have installed VirtualBox open it and click on "New" on the toolbar to begin the process of creating a new virtual machine.

Give a name to your virtual machine and select which OS you would be installing in it and click on "Next".

Enable "Developer options" on your HTC One X

Recently I noticed that the Developer options on my HTC One X was gone. I remembered before updating it to 4.2.2 it had the Developer options. Then I remembered that from Android 4.2 and higher the Developer options are hidden by default.

To get back Developer options go to "Settings > About > Software information > More". Once there tap on "Build number" seven times to enable it.

Remove Skype from taskbar in Windows when you close it

Skype has an annoying bug feature; when you close it, it does not disappear from the taskbar unlike other programs. To make Skype behave like other programs, in menu go to "Tools > Options". Under "Advanced > Advanced settings" uncheck "Keep Skype in taskbar while I'm signed in".

So now when you close Skype it disappears from taskbar but it is still running and you can see it in notification area of taskbar.
