What hackers do is not malicious destruction. They are a group of technicians who are keen on scientific and technological exploration and computer science research. In the hacker circle, the word hack is undoubtedly positive. For example, system hack is familiar with the design and maintenance of the operating system. Password hackers are good at finding out users' passwords. If they are computer hackers, they are experts who are familiar with computers and can make them obey.
According to Eric Raymond, the founder of open source code, the word is explained as follows: hack and crackte belong to two different worlds, and the basic difference is that hack is constructive, while crackte is dedicated to sabotage.
Hack originally meant workers who cut wood with axes, and it was first introduced into the computer circle from 65438 to 0960. Brian Harvey, a computer professor at the University of California, Berkeley, wrote when studying the word that MIT students are usually divided into two factions. One is tool, which means "dear" students, and their grades are all A; The other is the so-called hackte, that is, students who often skip classes and love to sleep in class, but are full of energy and like to engage in extracurricular activities at night.
What does this have to do with computers? Not at first. However, at that time, hack was also graded, just like tool used grades to compete. A truly first-class hacker is not ignorant all day, but keen to pursue a special hobby, such as studying telephone, railway (model or reality), science fiction, radio or computer. So the so-called computer hacker appeared later, which means computer expert.
It is necessary for a hacker to learn programming. Computers can be said to be designed for programming, and running programs is the only function of computers. By the way, mathematics is also indispensable. Running programs is actually operation, discrete mathematics, linear algebra, calculus and so on!
The term hacker is usually defined as a computer expert who invades other people's systems for illegal activities outside the circle or in the media. but
In Huck's eyes, such people belong to the next level of weirdos. If a hacker is an expert at making bombs, then CRACKTE is a terrorist.
Now, there are more and more hackers on the Internet. They only invade, sweep around with scanners, bomb people with IP bombs, and invade and destroy them aimlessly. They are not conducive to the development of computer technology, but endanger network security, cause network paralysis, and bring huge economic and spiritual losses to people.
