"Dear Mr. Sagawa Yan, your paper has passed the review of academic editors and will be published in the next issue of "World Number Theory", please..."
Sagawa Yan didn't expect that the paper would be published, and he calculated that it was more than 20 days, and it was about the same. "Now, Ran Sagawa's theorem will really become world famous."
Yan Sagawa thought to himself, the gift he gave to Xiaolan will be forever in the history of mathematics as he said.
The acknowledgment in the mathematics circles of Sakura Country is completely incomparable with the world mathematics circles.
Miyano Shiho noticed the upturned corner of his mouth, and asked curiously, "Is there anything good?" 770 "Well, the increase in reputation is a good thing?"
Sagawayan naturally wouldn't mention other girls in front of their sisters, even if they already knew about it. Hearing this, Zhibao frowned, "Are you going to publish a paper again?" But after thinking about it, he felt wrong, just publishing a paper is not worth the joy. "A paper with a lot of influence?" she asked tentatively.
"Well, it should be very big. It is estimated that there will be hundreds of letters every day." Sagawa Yan thought for a while and gave his own guess.
"I really don't know how your guy's brain grows..."
Zhibao said in a low tone, this guy, who has learned so many subjects at the same time, is even better than himself in biology. He really is a monster in scientific research.
Sagawa Yan's mood improved because of this letter, so he decided to try that floppy disk tonight to experience the power of the Duke of Darkness system. "By the way, when I went to see them in the morning, the three mice were still dead," Zhibao said.
In the past few days, they have not been idle, and tried more mice, but the three mice that Zhibao mentioned now are naturally the three mice that lost their ability to move at the beginning. According to their research and inference, the only normal one is probably because it is big enough and its muscles are not as developed as these three. ...Could it be said that this means that you must die now? .
Chapter 157 Xiaolan and Yuanzi's Antivirus Experience (Part 2)
The healthy little white mouse has now returned to its juvenile state. Every day it happily eats and jumps, and sleeps when tired. There is nothing wrong with it.
When Yan Sagawa and Miyano Shiho went to check its status every day, they felt that it was healthier than before. "Basically, it is certain that the lively little white mouse succeeded." Sagawa Yan said to Shiho.
"Well, but continue to observe for a few days. If there is no problem after 10 days, you can reduce the number of observations."
Shiho nodded in agreement.
At night, Xiaolan and Yuanzi rushed over. "Yan, we're back."
Before anyone came in, Yuanzi's vigorous voice had already entered the room. "Yuanzi, if you make too much noise, you will disturb others." Xiaolan said next to her.
"Haha, Xiaolan, you forgot what I told you, several houses around have already been bought by our Suzuki family, how could you disturb others." Sonoko said proudly.
With the Sagawa family as the center, the land within 5 surrounding houses has been bought by the Suzuki family, and they are all vacant now.
But although no one lives there, there are new users.
The shikigami of Sagawayan play multiple functions such as exterminating insects and rats and monitoring the surroundings.
The two women talked and laughed, took out the key, opened the door and walked into Sagawa's house.
Sagawayan walked out, "You guys came back just in time, I was going to try that floppy disk, and challenge the Night Duke virus, do you want to see it?" "I want to see, I want to see."
Yuanzi is very active. In the past, it was difficult to understand those obscure scientific research books. Now it is rare to see her boyfriend use a computer in person, and operate a simple one. Naturally, he has to read it carefully.
"Then I'll take a look too," Xiaolan put down her schoolbag and put on home slippers.
Having only experienced the Night Duke murder incident a few days ago, Xiao Lan is still very interested in the Night Duke virus that has attracted so many people.
Yan Sagawa led the two girls into the study, where there were three computers. "Yan, do we need to prepare so many computers?" Xiaolan couldn't help asking.
"Need", Sagawa Yan continued to explain while turning on the machine.
"This computer, which is completely physically isolated from the Internet and all connections, will be the main battlefield later." He turned on a computer and said.
"Then this one is used for monitoring and analyzing the situation. If necessary, the virus will be transferred to this one." He turned on the second one.
"The last one is for standby use," and the third one was turned on.
The computer that stores a lot of academic materials by itself will not be used.
The two women didn't know what was going on, they just looked at Sagawayan with stars in their eyes.
For 17-year-old girls, it is really difficult for them to understand computers.
Sagawayan scratched his head, suddenly feeling lonely as an expert, but then cheered up, with two girlfriends watching, he couldn't make any mistakes. "You sit behind me."
Sagawa Yan commanded, and then carefully took out the 3.5-inch floppy disk of the female high school student Gokaku Taizu, and put it into the first computer.
Everything is fine, the floppy disk is empty, there is no game software, no Night Duke virus, nothing can be taken out and nothing can be put in.
Seems like an ordinary broken floppy disk.
Sagawayan enters the bios interface, which is the basic input and output system of the computer and the lowest level of human-computer interaction.
He started to check the hidden things in the floppy disk under this interface. "General viruses are divided into two types based on their purpose."
Sagawa Yan tapped on the keyboard with both hands repeatedly, inputting commands, and said suddenly. "Um?"
Xiaolan and Yuanzi focused their attention on their boyfriend.
"Mainly destroying, this kind is generally spread wildly in the network, copying infinitely, and then after entering other people's computers, it will delete files or create spam to freeze the system, memory overflow, etc." "Purely for the purpose of harming people .”
Sagawa Yan said slowly, and the computer screen in front of him reflected a sequence of instructions composed of letters. "Then, is there another kind?" Xiaolan couldn't help asking. "There is another one."
Sagawayan turned his head and smiled at the two girls, his tone suddenly strong.
"That's the Duke of the Night, a virus for profit!"
Following his words, the computer screen in front of him suddenly had a strange black color constantly encroaching on the instructions and information on the screen.
Most of the screen was occupied, and the remaining part was glowing with blue light, just like the weird mask of the Duke of Night smiling at Sagawa Yan.
This is the Night Duke computer virus! "Yan, your computer screen?!"
Both Xiaolan and Yuanzi noticed the weird screen, and pointed at it.
"What did you say just now? I'll continue."
Sagawa Genhun didn't care, and continued to input commands with both hands, but the computer was out of control at this time.
"Those who destroy or hide important files like the Duke of Night are all trying to blackmail the computer owner."
As a computer virus, if it is destructive, how can it spread on a small scale, and it has been attacking commercial documents and important documents, no matter how you think, it is all for fraud and extortion.
So how can this virus disappear by itself? If you are the designer, you will only hide it for secondary use.
Things were exactly as he thought, when Sagawa Yan tried to check the bottom layer from the bios, he hadn't found anything, but when he tried to analyze it with hackers' methods, this cunning Night Duke virus came out.
But let it have great abilities, a computer that is physically isolated from all external connections is its cage.
Seeing that there was no response no matter how hard he tapped, Sagawa Yan simply gave up the computer.
Xiaolan came back to her senses first, ran to the computer, and took a closer look, "This is the Duke of the Night virus. I didn't expect that you found it (Zhao Zhao's)." Sa Chuanyan suddenly smirked, "Be careful, Xiaolan, that Duke of Night can infect people." "What?" Xiaolan was startled, and quickly withdrew her little hand, she touched the computer screen just now.
"Hahaha", Sagawa Yan laughed, "Little idiot, how could a computer virus be transmitted to humans." Sonoko also laughed, "Xiaolan, don't we have computer classes?" Xiaolan was ashamed, "For a while Forget it."
Immediately, she looked at Yan with a fierce look in her eyes, and her two small fists kept falling, hitting Yan Sagawa to stop him. "Let you scare me, let you scare me!"
It looked powerful, but he didn't have much strength when it fell on Yan Sagawa. It was obviously a joke between lovers.
"It hurts, it hurts," said Sagawa Yan, pretending to be in pain. "Xiaolan, let me help you!"
Seeing this, Yuanzi also joined in.
The three of them played around for a while before stopping. .
Chapter 158 Informatics LV2 (Part 3)
"Then what should we do next?"
Sonoko asked worriedly after he stopped playing.
She noticed that the computer was completely out of control. "Didn't I prepare two more?"
Sagawa said with a smile, in his arms was Xiaolan who punched him vigorously just now. Xiaolan struggled to stand up, "Then you go get it quickly." He sat down in front of the second computer.
There are layers of nets laid by him in this computer, just to catch the Night Duke virus.
Sagawa continued to explain to the two women, "This computer is also not connected to the Internet. The firewall inside, the anti-virus program written by myself in Go language, and the analysis program are the killer weapons I specially prepared." Xiaolan and Sonoko sat beside him, wanting to see how her boyfriend dealt with the Night Duke virus.
Sagawayan opened the local area network between the two computers. According to his speculation, the virus that is currently being activated will definitely infect more files desperately.
An ordinary document was passed over, and Yan Sagawa took it back after a while, and it went smoothly.
This surprised Sagawa Yan, he thought he had to use a floppy disk to copy it, but he didn't expect it to be transferred back smoothly. "The virus owner is very comprehensive. The transfer of files will not be affected, and the infection path will be increased."
Yan Sagawa rubbed his chin, feeling that the matter became interesting, but the desire for scientific research in his heart was also burning.
"I really want to take it apart and have a look, analyze the code inside, is it written in c, how to deal with it logically, and how it is related to the registry." Such a powerful virus was written with only c, then After the analysis is clear, using your own go language, you will be able to write a more powerful virus.
In the graphical interface of Sagawayan's analysis software, it can be observed that a command was transmitted from the seemingly ordinary document, and a copy command was spontaneously formed, and the background program began to continuously copy the document and the virus inside.
Sagawa Yan also hit back. The firewall blocked this folder and did not allow the file to call other system background resources. "Next, what else can you do?" He said to himself.
The two women next to him looked helpless and discussed in a low voice.
"It's over, Yan has entered the state of scientific research again, (cibe) probably doesn't remember us being around at this time." "Xiao Lan, we don't understand anyway, or we should make dinner." "Okay."
Xiaolan and Sonoko left Sagawayan's side lightly, and carefully closed the door of the study.
Sagawa Yan knew nothing and was still looking at the data on the computer screen.
Yaodao Ji stood quietly beside him, watching quietly.
The command issued by the Night Duke virus seems to ignore the firewall and still be able to use resources. Sagawa Yan was shocked, "This is the order!" He quickly called up this order for in-depth processing.
But the command itself is unremarkable, a simple call.
"The problem does not appear to be with the command, but with the file that issued the command."
Sagawa Yan called up the background log and found that the command called in the system turned out to be the system itself. "Cunning guy, you've disguised yourself as a person with high authority." The battle of wits and courage with the Duke of the Night is still going on.
This time it was replaced by Yan Sagawa who took the initiative to attack. He used the anti-virus software he wrote to check and kill the virus. "caught you."
The anti-virus program written by Sa Chuan Yan specially added codes that ignore permissions, and now, he caught the Duke of Dark Night's tricks.
He removed the part he grabbed from the surface, and saw the body of the code inside. "It turned out to be like this..."
The light of the computer screen was flickering, and lines of code in C language appeared in front of Sagawa Yan.
The core and logic of the Duke of the Night were exposed without any defense.
Inspiration came to Sagawa Yan's mind.
He quickly put aside the computer and turned on his personal computer.
Knocking with both hands, lines of Go language code appear on the computer.
He wants to develop his own virus program in go language now.
"I don't need blackmail, what I need is its camouflage ability, and then add it to transmit messages when connected to the Internet." Sa Chuan said that what he needs is a virus program that can help him obtain enough information. "The ability to camouflage and hide needs to be stronger..."
With the continuous burst of inspiration and the performance of the go language far surpassing this era, the combination of the two made his writing go very smoothly.
"Yan, it's time to eat," Xiaolan's voice from outside floated in. "You eat."
Sagawa Yan didn't even try to identify what he was saying, and responded casually.
The keyboard continued to make a crackling sound.
In the blink of an eye, Yan Sagawa had already coded hundreds of lines of code.
Xiaolan and Yuanzi both came in to have a look, and didn't bother him when they saw his condition, they just prepared the food silently.
"Hey, Dad, I'm staying at Yuanzi's house for one night today, um, okay, I'll pay attention, hang up and bye."
Xiaolan put down the phone.
She told Yuanzi a little worried about this state, so she decided to stay and take care of him, relying on Yuanzi's family being nearby, Xiaolan didn't care anymore.
"Let's watch TV, I don't know how long it will take," Yuanzi suggested.
"But will it disturb Yan?" Xiaolan worried that it would affect Sagawa Yan.
"We can play very quietly."
Yuanzi has already considered this problem.
The hour hand of the wall clock moved a little bit, and soon reached the position of 12.
Sagawa Yan left the keyboard with both hands, and let out a long breath of relief.
Finally finished!
The virus program developed with go language has the ultimate hiding ability, powerful disguise and impersonation ability, and encrypts the returned message data.
It is no exaggeration to say that this is the most powerful virus software in this era. Computers without internet connection can prevent its intrusion and eavesdropping.
The moment he finished, a voice sounded.
