Why switch expression does not work with float types?

Have you people ever thought of why switch statement does not work with float/double types?
I have read in text books about the constraints of switch statements but i have never thought(infact i didnt take pain to find it out :P) why switch cant be used with floating point values,
but today one of my friend asked me about it(she is doing civil engg)as she has a viva tomorrow on c programming.I was not able to answer her immediately,i searched a lot and i found some answers.I would like to share it with everybody.
The reason is...

Save Energy-Go Green

SAVE ELECTRICITY, REDUCE BILLS
Energy,its very precious,dont waste it.We have the "power",save energy..I have collected some of the tips for reducing electricity usage.
Illumination
 When working on a laptop, you may not need much ambient lighting; you can use a USB lamp (5V DC) as opposed to a regular 40W or 60W bulb.
 For a night lamp, use a 0 watt bulb or an LED (light emitting diode) lamp.
 Walls in your house which get considerable natural light should be painted in lighter/pastel shades to reflect light. This way, artificial lighting won’t be needed during the day.
Desktop computers
 Wherever possible, use LCD (TFT) monitors instead of CRTs (cathode ray tubes). If you aren’t keen on gaming, avoid installing a graphics card, in particular, models with liquid cooling solutions.

Restoring grub

GRUB Loading stage 1.5.
GRUB loading, please wait...
Error 17
This is a common error people find when uninstalling windows where linux is also present in that machine.This is because your GRUB may have lost due to uninstalling.

This method puts GRUB back on the MBR (master boot record) of the hard drive instead of in the root partition.
To fix this

wget: Download entire websites easy

wget is a nice tool for downloading resources from the internet. The basic usage is wget url:

wget http://linuxreviews.org/

Therefore, wget (manual page) + less (manual page) is all you need to surf the internet. The power of wget is that you may download sites recursive, meaning you also get all pages (and images and other data) linked on the front page:

wget -r http://linuxreviews.org/

But many sites do not want you to download their entire site. To prevent this, they check how browsers identify. Many sites refuses you to connect or sends a blank page if they detect you are not using a web-browser.

GParted-Partitioning Software

No matter which operating system you want to have installed on your machine, there's one thing they all have in common: partitions. These are logical pieces of your actual hard disk space, defining the size and the file system format for the operating systems and data that are going to be placed on them.

Being able to control the partitions is one of the most basic, most important aspects of mastering your operating system. If you have the knowledge and confidence to manipulate the layout, create it, change it or delete it, you can adapt your hardware to your varying needs, without having to blindly rely on default setups defined by vendors or other people.

I will tell my experience in using GParted ...
Around two months back,I installed ubuntu 9.04 on my friend's lap by partitioning

Fall in love with Chrome

Today i really wanted to appreciate Google Chrome,becoz it helped me a lot today.I was really fed up downloading things with firefox and IE8 for many days,it was terribly slow compared to Chrome.Finally i installed chrome on my lap yesterday night and start downloading using it.It was really a surprise for me to see that it works smooth compared to two other top browsers.The download icon that comes at right most corner is very useful to see the status of downloading files quickly.It has a very attractive user interface also.All credits goes to Chrome.... :)
