file.tex:0:Emergency Stop

This latex error is a simple one but can make you go crazy. It does not give you much clue about where exactly the error occurs and the cursor goes to the beginning of the file. Well, the culprit lies in the end of the file. It is when we miss to end the document by mistake.
So just add \end{document} in the last line of the file and the error vanishes!

Turn on Bluetooth in Ubuntu 12.04

I did not find it so straightforward to setup bluetooth in my ubuntu 12.04 system. So I had to look up couple of sites to fix my problem and successfully transfer data via bluetooth.

The following link gives a nice, detailed, step-by-step instruction on how to turn on bluetooth in ubuntu.

However, I was not able to activate any button. They all appeared deactivated to me. If you are facing the same problem, then you have to do the following setup in terminal:

$sudo hciconfig hci0 reset

This activates the buttons and lets you do your setting. (Refer:

We need to check the option  "Receive files in Downloads Folder over Bluetooth" in the menu opened in Personal File Sharing. In ubuntu 12.04, it is found in the path: 
Applications ->System Tools->Preferences->Personal File Sharing.

The files transferred to the system are stored in the folder "Public" in the homepath.
