What is Hacking ?

Hacking is the practice of modifying the features of a system, in order to accomplish a goal outside of the creator's original purpose

The person who is consistently engaging in hacking activities, and has accepted hacking as a lifestyle and philosophy of their choice, is called a hacker

The Hacker Attitude

Hackers solve problems and build things, and they believe in freedom and voluntary mutual help.

To be accepted as a hacker, you have to behave as though you have this kind of attitude yourself.

And to behave as though you have the attitude, you have to really believe the attitude.

Philosophy

1. The world is full of fascinating problems waiting to be solved.

2. No problem should ever have to be solved twice.

3. Boredom and drudgery are evil.

4.Freedom is good

5. Attitude is no substitute for competence.

Basic Hacking Skills!

1. Learn how to program.

2. Get one of the open source unixes.

Linux Philosophy!

Linux is Free and Open-Source

Free as in the sense ,Freedom of Source

Since Linux is Free and Open-Source, there are many flavors of Linux

Open Source - Definition

Owners of Proprietary Softwares closely guard their Source code, and thus cannot be modified by anyone except them

On the contrary Open Source softwares means, the source code of the software is OPEN to general public

Source Code is made open so that people too can contribute to the development of software

History

In 1970’s AT&t Bell labs funded a project to create a new Operating System and came up with UNIX.A very famous and powerfull operating system

Soon after contribution from various Universities AT&T licensed it and made it proprietary making it unfit for teaching and learning

Richard Matthew Stallman RMS

The Founder FSF and GPL

There’s a temptation for programmers to say “Start with PHP or Java”

They say this because:

2. it's how they learned ;)

IGNORE them

One of the many places to kill time !

Beautiful Strings!

Given a string s, little Johnny defined the beauty of the string as the sum of the beauty of the letters in it. The beauty of each letter is an integer between 1 and 26, inclusive, and no two letters have the same beauty. Johnny doesn't care about whether letters are uppercase or lowercase, so that doesn't affect the beauty of a letter.

You're a student writing a report on the youth of this famous hacker. You found the string that Johnny considered most beautiful. What is the maximum possible beauty of this string?
