Reborn Ace Hack

After some persuasion from Xiao Yuan, Liu Dong seemed to be lost in thought. Until the lecture started, he kept his head down and said nothing for most of the time. Only Duan Yanyue came on stage, introduced the professor giving the lecture, and announced the start of the lecture.

At that moment, he just raised his head and stared at the beautiful figure on the stage, refusing to let go.

The professor giving the lecture is named Smith Bull. He is an old American man who looks to be in his fifties. He comes from the University of California, Berkeley. The content of the lecture is about a research he is currently engaged in. The specific topic is network chaos system.

A review of research.

A chaotic system is an evolution process in which individuals are disordered but the overall development is orderly. The science of studying chaotic systems is called chaos science. The mathematical model of chaotic systems created by chaos science is called a chaos model. The initial stage of this model

The state is very similar to the situation in which the heaven and the earth were not yet opened as described in the ancient myth of Pangu of China. Since the individuals in the system have not yet started their activities, the entire system will be in a state of complete disorder.

This disordered initial state will gradually evolve when the individuals within the chaotic system begin to act, and under the influence of all disordered individuals, the entire chaotic system will develop in an orderly direction.

“If a horseshoe is lost, a horseshoe is lost; if a horseshoe is lost, a war horse is broken; if a war horse is broken, a king is lost; if a king is lost, a war is lost; if a war horse is lost, a war is lost.

One war destroyed an empire."

Smith now typed this paragraph in English on the slide, and added a Chinese explanation next to it.

"First of all, I would like to thank the beautiful Miss Duan Yanyue for helping me translate this paragraph into Chinese." Smith first expressed his gratitude to Duan Yanyue, who was sitting next to the podium, in fluent Chinese, probably because he felt that his Chinese level was really good.

It was limited. After a few strenuous lectures, it gradually turned into an all-English lecture.

Xiao Yuan's reading ability is very good, but his listening ability is quite limited because he has received very little training. Fortunately, the old man on the stage has a pure voice and does not speak too fast, combined with a very detailed projection

He can understand a lot of the movie.

However, Jiang Hua showed a lack of interest and was not interested in the content of the lecture at all. After looking around at the beautiful woman for a while, he felt bored and fell asleep on the table.

Liu Dong sat upright and listened very carefully. Xiao Yuan didn't know whether his English level could reach the level of complete understanding, but judging from his thoughtful expression, it should be about the same.

One of the most important arguments in chaos theory is that the development of chaotic systems is very sensitive to the influence of some external factors. Some seemingly very small influences will gradually amplify over time, just like Smith's introduction to chaos.

It’s the same story as the classic horseshoe nail that Xue Er punched. Although the horseshoe nail is small, it can ultimately destroy a country.

What Smith said made Xiao Yuan easily think of the butterfly effect. The weak influence of a butterfly's wings on the airflow may cause a hurricane. In addition, what the ancient Chinese said about the slightest difference can make a thousand miles, is all about this.

reason.

Listening to Smith's explanation, Xiao Yuan had a preliminary understanding of what a chaotic system was, and then thought that the real world is also a large chaotic system. From a local perspective, everyone is doing everyone's things, and they are all different.

, this is local chaos and disorder, which is what is called chaos in chaos theory, but from a macro perspective,

If we regard all people's activities as a whole, then this whole is regular. Everyone, even a baby, will have more or less impact on the world, and even under certain conditions, a certain person's existence will have more or less impact on the world.

A seemingly small impact will gradually be magnified and even change the historical development trend of the entire society.

"I just don't know what kind of impact I, a reborn butterfly, will have on our real world, and what kind of impact it will have on people who have intersections with me, or even those who have no intersections with me?"

Xiao Yuan thought to himself, and when he thought about it, he turned his head and glanced at Jiang Hua, who was sleeping next to him, and thought that if he hadn't been reborn, there would probably not be a person named Xiao Yuan in this guy's life.

, and would not appear in such a lecture that was extremely boring for him, and fell asleep.

"What about Liu Dong?"

Xiao Yuan glanced at Liu Dong again, and a number of thoughts also went through his mind. Liu Dong seemed to feel Xiao Yuan looking at him, turned his head to look at Xiao Yuan, and whispered: "This chaos theory is very interesting.

There is also a teacher in the School of Mathematics who is studying this thing. I once listened to one of his lectures, and he talked about the same thing, but that teacher studied pure theory. This foreigner’s research is more specific. Some of his achievements are the application of chaotic systems.

It’s down to specific subjects.”

Xiao Yuan smiled and did not answer Liu Dong's words. Instead, he continued to focus on the podium and listened carefully to the lecture.

"... Over the years, my research group and I have been committed to using chaos theory to study the existence of interconnections, and using chaotic systems to model network systems..." Smith gave an overview of the theory of chaotic systems and

After the application scope, they began to focus on their research content-network chaos system.

After Smith initially described the content of their research, he seemed to feel that everyone's response to his lecture was not particularly enthusiastic, so he simply stopped talking about the boring mathematical derivation and mathematical expressions that most people could not understand, and quickly moved backwards on the slide.

After flipping through a few pages, he came up with a point of view that shocked everyone.

"If you look at the Internet as a whole system, this system obviously has all the characteristics of a chaotic system. Everyone's activities on the Internet are disordered, but from a macro perspective, the Internet is an orderly system.

, we even discovered that this system is alive, it will be injured, sick, and even sick..."

The students listening below were obviously attracted by Smith's point of view. When he put forward this point of view, there was a burst of whispers below.

"The idea of ​​treating the Internet as a living entity is very novel," Liu Dong said.

"Perhaps we can design such a program to simulate the operation of a chaotic system, or even put it on the Internet and let it develop freely in the chaotic environment of the Internet. I wonder what kind of thing it will grow into in the end?" Xiao

When Liu Dong was talking to him far away, he had a sudden thought.

"Why do you have such an idea? Is it technically possible to realize it?" Liu Dong turned around in surprise, glanced at Xiao Yuan and said.

"There's nothing you can't think of, but nothing you can't do." Xiao Yuan said.

"This idea is a bit crazy. If you finish writing it, tell me and I will see what you can come up with," Liu Dong said.

"...Computer viruses are so similar to human viruses that they can damage network systems, and network systems, like human systems, also have very strong immune systems, and many anti-virus software and firewalls running on the network are like

White blood cells will kill these viruses one by one. Although the users of these software are simply maintaining their personal safety and do not realize that these software have become part of the immune system of a system, it is precisely this kind of

Unconsciousness makes the network system more and more consistent with the characteristics of a chaotic system..."

Smith is still making his point.

"...If computer viruses and security software are the destroyers and immune systems of the network system, then the hackers who create viruses are like some heavily polluted factories in reality, each one exuding disgusting

The stench of developing those disgusting malicious programs..."

It seemed that Smith had a very bad impression of hackers. He was soon drawn into hackers by computer viruses, and his words became sharp in an instant.

Other students may not have any feelings, but Xiao Yuan noticed that when Smith mentioned hackers, the word he used was hacker. This word was a kind of belief for him, but the old man on the podium was using the worst words.

He criticized it with words, and his brows couldn't help but

He frowned, and even wanted to stand up, interrupt the other person's words, and argue with him, but in the end he decided to endure it. Generally, before the end of the lecture, there would be a question and answer session. He decided to wait until this session before proceeding.

Discuss this issue with the old man on stage.

The reason why Xiao Yuan decided to discuss this issue with the old man was because this was a lecture with hundreds of people in the audience. The old man Smith's prejudice against hackers would be conveyed to everyone here, and he happened to be standing up to a famous foreign scholar.

Such a result can only further deepen people's already biased tendency towards hackers.

And Xiao Yuan felt that if he discussed with Smith in public, even if he could not convince the old man to accept his ideas about hackers, he believed that the audience sitting below would not all agree with him. After listening to his explanation, there would be some doubts.

His subordinates will check it out. As long as one person recognizes his idea, he feels that he has achieved his goal. From this point of view, at this moment, he has subconsciously regarded himself as a preacher.

Smith's lecture lasted for more than forty minutes and then ended. In the following time, Duan Yanyue came out again and began to organize people in the audience to ask questions.

Probably because most of the students were interested in what Smith said, and his explanation only touched on the point. All the students had a lot of questions. When Duan Yanyue announced that he could raise his hands to ask questions, there were a lot of people immediately.

Raising his hand, Xiao Yuan also raised his hand.

"That classmate, you come to ask a question." Duan Yanyue saw Xiao Yuan raising his hand and was the first to call his name.

"Hello, Mr. Smith, your lecture has exposed me to a subject and field that I have never been exposed to before, and it is eye-opening. I have a few questions that I would like to discuss with you, okay?" Xiao Yuan said politely first.

He made some opening remarks. In order for everyone to hear clearly, he did not use English, but directly used Chinese.

"Okay, please ask, I'll discuss it with you." After listening to the translator next to him, Smith nodded and smiled at Xiao Yuan.
