Bit Mania [Hacking]

"A few days ago, more than [-] million yuan was allocated to develop a parallel computer equipped with VLSI. At that time, those old men rushed to take over. This is a core scientific research plan, something that can be included in the strategy of strengthening the country, and the funding is high. No worries, if you accidentally do a good job, you will become a hero... Fang Shuxin, do you know that he is the Ph.

"Is he an aviation guy here to join in the fun, install a liquid engine on our computer..."

"The higher-ups saw his plan and immediately praised him."

"No way..."

"Then turn around and send him to command the launch vehicle in the predetermined waters of the Pacific Ocean,"

"Haha! You deserve it..."

"His wife knows, she was a famous talented woman from the Department of Engineering Mechanics at the University of Michigan. After getting the news, she insisted not to let him go. The reason was that Fang Shuxin was allergic to seafood..."

"It's too ridiculous..."

"No matter how much you talk, it's much better than you occupying the state's authority to register for the Internet! ... Why have you retired from our national computing center and lived in seclusion for the elderly? Is there anyone like you?!"

"Hi." Song Yubai choked, and said angrily, "...I think you will be willing to help me."

"Let's talk about it and take you back to the capital, okay?" Mu Yun turned his finger pointing at his old friend's nose in the same direction, and when he met a figure next to him, he coughed lightly: "Little friend, things like occupying state authority, we will It's also helpless... so I have to arrest someone and go back and explain, is it you or your master, what do you think?"

Zixin said: "This is not the teacher's business, I did it."

"In this way, as long as you can prove that you have the strength to do this, we will let that old Dong go... Your teacher, otherwise, take him away!"

After the old man finished speaking, he leaned comfortably on his seat and gave the young scholar beside him a wink.

Yao Yizhi stood up knowingly, pushed the glasses on the bridge of his nose, and said to Zixin, "Let me ask you for advice."

Mu Yundao: "Although he is only 31 years old, he is already a person at the level of a doctoral supervisor in computer science. He is qualified to give people a doctorate... Although he is a bit suspected of bullying a child, I will tell him to stop as soon as possible."

Yao Yiyi, who looked harmless to humans and animals, just smiled shyly amidst the slight gasps of the Song disciples around him.

"Come on." Zixin rolled up his sleeves expressionlessly.

"Don't hold back, if that little guy is really the chief engineer." Elder Mu bit Yi Zhi's ear and said, "If not, then don't hold back, I've already seen that old guy opposite me upset... what the hell , take in an apprentice who is cuter than me, let him know how good we are, and try to get him here."

"Cough... I know." The young doctoral supervisor, who was not as cute as others, answered dumbfoundedly.

"Don't keep your hands, look at that old treasure across the way... This young man is probably not just an ordinary Ph. , I must kill his prestige today... I have long been unhappy with him, and I will go around talking about him for fear that the world will not know when I have a powerful apprentice."

Zixin heard the words, and patted the old man in front of him comfortingly: "Sure, I won't let them take you away!"

"Good boy!"

Discussions inevitably require a fair environment. The computer room of the Song family was quickly cleared out. Yao Yizhi and the others brought a laptop computer. Although it is portable and can be taken with you, it also has the basic functions that a computer should have, but its performance is sure. It couldn't compare to Zixin's desktop computer, so they both decided to use computers with the same configuration - the Intel 80386 processor is a classic and a model in this era, and now it is their weapon without hesitation.

Yao Yizhi sat in front of the computer: "Compare to what?"

"Whatever." Zixin bent down, pressed the power button, and the computer entered a self-test.

"Whatever...then it's better than the disk operation department...uh," Yao Yizhi said halfway, when he saw his teacher glaring at him fiercely, with an angry look on his face. In desperation, he could only change his words: " ...I think it's better than that."

"Which one?"

"Data organization."

Seeing the old man's face finally calm down, Yao Yizhi touched his nose with some shame.

Hearing this, Zi Xin couldn't help but look at the man sitting opposite her a few more times. This proposition...

Those who have read martial arts novels may understand it more easily. The data organization ability between two hackers is the same as two martial arts masters, abandoning all internal strength and simply fighting with exquisite sword moves!

Once there is no external thing, what is the comparison?

——It is the most fundamental and deepest grasp of the weapon of the sword, which depends on the understanding of the way of the sword. I am afraid that only at the last moment, when the data tower is fully built, can one tell the difference.Applied here, it means abandoning all the machine advantages that the computer can provide, and simply comparing whose algorithm is more sophisticated, whose management data level and structure are the most unbreakable, whose logic is more rigorous, and in the shortest time. The data is arranged in a neat phalanx of soldiers, and their respective calling instructions are arranged. When they are needed, they can be called out with the lowest computer resources at the first time.

This subject plays an important role in computer applications. The main frequency parameters of computers are measured in millions of operations per second. As long as a good data structure can increase the call speed by one thousandth, it will almost turn the world upside down in the actual information war. breakthrough.Just imagine, assuming that the floating-point calculation speed of supercomputers in two countries is the same, that is, when the performance level is the same, one of the data transfer speeds is higher, then the processing of any problem will be ahead of the other, and it will always be faster than the other. So a few tenths of a second or even a few seconds - what can a few seconds do?A nuclear bomb is about to be dropped on another country, but this country's anti-missile system is a little bit slower to respond, huh? ...

"Data organization...data...organization?!" Song Yubai murmured, and suddenly seemed to think of something, his eyes widened in astonishment: "He is!—"

"Yes," the seat next to him sank, and a person sat next to him. The expression on Mu Yun's face was obscured by the light from the computer screen: "He is the one who studied in the United States for nine years. children."

"...that technological spy whose true identity no one knows?!"

Mu Yun nodded: "Fake death to return to China, there is no small piece of paper on his body, he has installed all the technology in the world's top computer field in his mind, and finally came back... Oh! What are you doing? Hit me!"

"You were the one who beat you!" Song Yubai pushed him to the ground: "If you dare to bully my apprentice, seek a beating!..."

"Hey! Don't be so lacking in self-confidence... Hahaha..."

On the other side, in the computers in front of the two young people, there is a huge data randomly intercepted from the Internet, with a total of 46G. A senior brother named Ge Zheng is standing in the middle of the field. The outstanding figure, who was holding the timer in his hand at this time, raised a hand after getting ready looks from the two of them respectively.

"preparation--"

"start!"
