Android on Ubuntu & tricks with Thinkpad laptop

Want to install android on a virtual machine on your Ubuntu? Well it's not that hard, have a look at this tutorial which simply tells you how to do it :-)

http://www.howtogeek.com/164570/how-to-install-android-in-virtualbox/

Important Update : Talking about it being easy, if you are having a Lenovo or Asus laptop remember to download the special iso file made for laptops with special hardware. android-x86-4.0-r1-thinkpad.iso in my case. Also after you are finished installing and you do not have the mouse in the Virtual box windows when u start the Android, read this article at PC world which helps you with that :-P

http://www.pcworld.com/article/2048220/hybrid-hijinks-how-to-install-android-on-your-pc.html

It basically only is saying the following which is useful for you : "Click Machine in VirtualBox’s toolbar, and select Disable Mouse Integration. Dialog boxes may appear; if so, click through them and continue. Disabling mouse integration allows you to manually control whether your mouse is controlling your primary OS or Android-x86. Pressing the right Ctrl button on your keyboard switches between the two operating systems. To swipe, click and hold the mouse button, and then move the mouse.
With that taken care of, you’re free to explore Android on your PC!"

So you forgot your Ubuntu password ???

If you're unlucky enough not to remember your Ubuntu password, re-installing the OS is not the only option you've got :-) Follow the instruction in following link in Ubuntu Recovery to reset your password :-)

C:\Windows;C:\Windows\system32
are missing ...

Adding a folder that is not on the frequent list, to pinned list in Windows Explorer

You can open folders from Windows Explorer shortcut on Windows 7. You have 2 lists when you right click on this folder, Frequent and Pinned. The frequent folders are those which you have visited frequently and the pinned ones are those which you have chosen to have it permanently in that list. It'e quite a useful shortcut, believe me.

One way to add folders to the pinned list is simply to choose them from frequent list and press the pin button in front of the folder name. However not all the folders that we would like to add to this list comes up in the frequent list. What to do? The solution is quite simple. You only need to drag that folder on the Windows Explorer shortcut on your taskbar  and release it. The folder would be added automatically to your pinned list.
