nmap [ network mapper ] - A powerful network mapping n scanning software.

Nmap is a powerful network scanner which allows you to discover host, their operating system, scan their ports and many more tasks on a network. The software was originally written by Gordon Lyon (also known by his pseudonym Fyodor Vaskovich) used to discover hosts and services on a computer network. It is generally used as  a command line interface [ CLI ] but also support graphic user interface [ GUI ]. But mostly people would love to use it as a command line interface rather than using the GUI. It is a very powerful tool which you will surely feel while using it. So what are you waiting for ? Go visit Fyodor's website where there are detailed information and guides on how to use the nmap scanner. You can also download the software through the website.

Do use the software with care.  -_-

How to get the old facebook chat.

Many of you must not be liking the new facebook chat that they have introduced recently. So if you would like to switch to the old facebook chat you can do that easily by following these easy steps:

Firefox users: Just visit this Firefox add-on page and click on the button which says "Add to firefox". After downloading the add-on you must be able to use the old facebook chat. Most probably you won't need to restart firefox for the changes to take effect. You are done with it.

Chrome users: Chrome users need to download this app and you just need to refresh the facebook website and you will get the old facebook chat.

Opera users: Download this app and you will get the old facebook chat.

Important: Sometimes the facebook chat will be showing 0 Friends online even if there are friends online so you just need to go offline once and come back online and it will show the online friends once again.

Facebook tip: Some of you guys must be having many such friends to whom you would not like to chat

or whatever. So you can make a friend list so that you will be seen online to only those people you choose. This can be done by making friend list. When you click on chat window you can see the friend lists option on the top left. Click on it and type whatever name you would like to keep and hit enter. A small button will appear right next to the name you mentioned and even when you hover your mouse on your friend list name an edit button will appear on the right side of the name which will let you add friends to whom you wish to be seen online. The button will appear green which means you are online and grey means you are offline.

Hope it helped you.

Creating an invisible folder..

Have you ever wanted to hide any folder on your PC from your dad, brother or your friends ? You can do that without using any software. Yes, you heard it right! But I can not say that it is a foolproof idea. But if you are careful, no one will be able to see your folder. It is always a good idea to hide such things in this folder that even if you get caught the consequences are not bad enough.

So follow the below steps to make your folder invisible:

1. Rename the folder by pressing the ALT key and 0160 using  Num Pad. ie: "ALT + 0160" You actually don't have to press the + sign in Num pad. Just press and hold down the ALT key and type 0160 using Num pad, thats it. After this press enter and  you will be able to see an empty space there that means you are half done.

2. Now that we have renamed the folder as an empty space we will now have to change the folder icon to something that could not be seen.

• Right click folder

• Go to properties

• Select the Customize tab and then press the Change Icon button that is seen at the lower left corner.

• Look out for an empty space and select it and then press OK.

• Done. Your folder is now invisible.

 Note: If you press "ALT+A" which is a shortcut to SELECT ALL then even the invisble folder gets selected and the folder can be seen clearly.

--> Below is an images to guide you through the whole process easily.

You must be a bit confused by watching 3 folder with a same name ie: "Something"

Even you can create folder with same name by using   "ALT + 0160"

The three folder with the same name in the image above are actually not the same name.

 Folder 1: Something 

 Folder 2: SomethingALT0160

 Folder 3: SomethingALT0160ALT0160

Hope you understand what I am trying to explain above.. Try it..  :)

Good luck.
