Imagine the following situation.

My friend bought a new mobile phone. It has many functions, and he paid it a lot.
The only bad thing is that the instructions is in English, and he does not know English language.

And so it’s been a few months from when my friend bought this phone… and I note that my friend does not send messages with his new phone, but when someone sends him a message (SMS), he call that person immediately.
I asked him why not he send a message back. He said to me that he do not know how to handle any function on his mobile phone! I asked him: “so why not you see how it goes, push buttons, in the end you will learn?”

Happiness, greatness, pride-nothing is secure, nothing keeps.
- Euripides

If you want total security, go to prison. There you’re fed, clothed, given medical care and so on. The only thing lacking … is freedom.
- Dwight D. Eisenhower

What is security? This is a very interesting topic. I think a lot about the security on the past few days. I realized that if I can understand security, I can much accelerate mine development and get fantastic results.
