An interesting essay I've read it recently.

In a sense there's just one mistake that kills startups: not making something users want. If you make something users want, you'll probably be fine, whatever else you do or don't do. And if you don't make something users want, then you're dead, whatever else you do or don't do. So really this is a list of 18 things that cause startups not to make something users want. Nearly all failure funnels through that.

Since spreading of sniffers and intruders on the web,I decided to write this blog entry that is talking about one of the most famous arts in the security science which is called "Steganography"!.

At first glance,maybe it's a strange term for some of you.But as I think after reading this topic you will understand it.

Copied from wikipedia

Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message. By contrast, cryptography obscures the meaning of a message, but it does not conceal the fact that there is a message. Today, the term steganography includes the concealment of digital information within computer files. For example, the sender might start with an ordinary-looking image file, then adjust the color of every 100th pixel to correspond to a letter in the alphabet -- a change so subtle that someone who isn't actively looking for it is unlikely to notice it.
