Remember the Units!!!

Yes, remembering the unit is not always fun for kids doing first year of Physics.

I think this one is neat trick:
Newton walks a meter and becomes Joule; Joule sits on time and becomes Watt

Newton walks a meter and becomes Joule; Joule sits on time and becomes Watt

Formula:
Work = Force*distance (Joule)
Power = Work/time (Watt)

Irritating bottom toolbar on virtual box-Ubuntu

Irritated by the small toolbox that pops up on the seamless mode?

Me too!

some suggested adding a new toolbar so that it will be like double decker.

some suggested removing it. http://superuser.com/questions/154182/remove-virtualboxs-lower-machine-configuration-bar-in-a-running-vm

I do not recommend it as it is sometimes handy.

So, my fixed-it solution for now would be to set the size so that it is just big enough to dwarf the irritating  config bar.

Another solution is to hang the toolbar upside instead of keeping it down there on bottom.

Less annoyance is always good! 

How to share Folder in Virtual Box

First become the super user

$sudo passwd root

On the Virtual Box: go to devices > shared folders and add a folder.

{I shared a folder named SharedVB (folder on windows) on D drive and gave it a name: SharedVB}

Then go to shell (again in the Virtual box) and do

$ sudo mkdir /mnt/Dshare

$ sudo mount.vboxsf SharedVB /mnt/Dshare
 The shared folder is up and ready.

The benefit is that one can copy from windows and access it from Virtual box.

We Trust you anyways... right?

Go ahead, it must be critical stuff that you wanted to install:
:P
