Bit Mania [Hacking]

Qin Yaode raised his head mechanically and slowly, and what he saw was light blue washed jeans and a beige padded jacket. On top of it, a delicate and delicate boy's face with unnatural blush on his cheeks, and on top of that, a cape. The coffee-colored teddy bear cap is ridiculously cute.

He rubbed his eyes, then picked up the manuscript paper in his hand and glanced at it, the design plan of the public land mobile network, very good, that's right.

Standing in front of him was a junior high school student, well, that's right.

"Uncle, can you give it back to me?" the boy said again.

Qin Yaode came to his senses in a jolt, he forced himself to calm down and accept this unrealistic reality, coughed lightly, and said, "Little...well, kid, did you write this?"

Luo Zixin nodded affirmatively: "Yes."

"Can you tell me about your thinking?"

Zixin didn't doubt that he was there, because of his height, he didn't have to squat down at all, he only needed to bend slightly, pointed at the manuscript paper in Qin Yaode's hand, and briefly explained it to the man squatting on the ground.

Qin Yaode nodded again and again, and couldn't help but be shocked by the profound knowledge of this unattractive boy in front of him. The application of formulas and theories seemed to be at his fingertips, without much thinking, and his ideas and whimsy were called uncanny workmanship.

At this moment, he felt the paper being pulled out in his hand, Qin Yaode saw the boy took the paper and was about to leave, so he quickly reached out and grabbed the other's arm: "Wait!"

Someone turned around and looked at him questioningly.

Qin Yaode looked at the bewildered face of the boy in front of him, and an idea quickly appeared in his mind, he said: "This idea on paper, do you want it to be put into practice and become a reality?"

Now it was Luo Zixin's turn to be taken aback for a moment, and then he replied affirmatively, "Of course."

Qin Yaode quickly calculated in his mind: "I can provide you with this opportunity now! As long as you give me the content of this plan, I can help you practice it. Think about it, when the time comes, Huanjiang Town residents will benefit from your creativity!"

"All benefit from my hands?..." Luo Zixin's eyes lit up, he thought of Liang Zhang's eldest brother, if this transformation plan can really be implemented, sister Xue and brother-in-law will no longer have to be troubled by poor signal reception up.

Thinking of this, Zixin happily agreed to the other party: "Okay, I will finish it for you, but I'm afraid I can't do it today. I have other things. Uncle, you can come to me some other day."

As he spoke, he hurried into the house without waiting for Qin Yaode to say anything else.

Qin Yaode's expression changed, and he wanted to catch up, but was blocked by the closed gate.

The man returned to his home with mixed feelings, and sat on the sofa, frowning deeper and deeper. He remembered an old saying that the night is long and dreams are many.Although the boy agreed to him now at a young age, if the child goes back and tells his parents, the adults will understand a lot about the twists and turns... I am afraid that by then, this matter will not only not be so easy to achieve , On the contrary, it may cause him big trouble.

Thinking of this, Qin Yaode heaved a sigh of relief, feeling powerless.

Here, Luo Zixin returned home, took off his hat and scarf and hung it up. In fact, the reason why someone hurried home today was also because of an important matter.After he put the small dishes he had brought back on the dining table, he couldn't wait to go back to his room, took out the chip and plugged it into the computer motherboard, returned all the parts to their original positions, turned on the power, rubbed his frozen hands, Pressed the power button.

The computer made a sound of normal operation, two green and one red indicator lights were jumping, and the system entered the self-test. After a while, the color graphical operation interface of the MacOS system appeared in front of Luo Zixin.

Zixin swallowed excitedly. As expected of the teaching equipment of a well-known university in the country, most of the books he saw in the library described the DOS system, and the one in front of him was obviously much more advanced than the former, and it could support Hierarchical file system and larger capacity storage device, can use floppy disk or hard disk.

Luo Zixin quickly entered a series of commands to call up the function parameters of this computer to view all aspects. The program statements that seem obscure to outsiders, but to Zixin, they are like delicious food presented one after another, full of color, flavor and taste. .The Apple II was pinned on the workbench by someone without any resistance, and was stripped off without any restraint.

"Huh?" Zixin opened a software source program, which is a half-written database system. As a semi-finished product, the first half of the software seems to have been repeatedly modified and optimized by the developer. It can be seen that the developer's programming level is not high enough. Even if it passes the test, at least the program statement is quite satisfactory, and it is still very rigorous, but it stopped abruptly on a key issue.

Luo Zixin was holding his chin to see the happy place, but was cut off abruptly. He shook his head in disappointment, and muttered: "Actually, as long as you follow the four characteristics of ACID, it's okay to not perform type checking..."

While talking, he stretched out his hand to scroll up, deleted dozens of lines of code, and added a few lines behind, and finally debugged the program. Seeing that the database system was running normally, he closed the code with satisfaction. dropped it.

Someone who had no idea what he was doing quickly put this little episode behind him and happily poked around on the Mac, seeing where the settings were wrong, and fixing them one by one, Even some potential problems in the system let him find a way to solve them. If he encounters functions that he is not very good at calculating, he will hide these problems or set up misleading logic to avoid the problems they may expose.

After doing all this, Luo Zixin was not surprised to see that the moon was already high outside, and there was a set of clean clothes by his hand——has Dad been here? ... He may have been too involved and didn't notice it at all. Now that I think about it, it's no wonder that his right ear hurts faintly, probably because he was pulled again.

I really don't know why those elders like to pinch him, someone rubbed his ears sullenly, picked up his clothes and ran to take a shower.

Early the next morning, Lin Guang and Li Yunze came to Luo Zixin's house by bus, moved the computer away under the reluctant gaze of the boy, and paid a lot of money.

As the computer disappeared from sight, Luo Zixin also seemed to be drained of his strength. Today is Sunday, there is no class, and the computer was sent back. He took out the library card from the drawer, and finally decided to spend time in the library. This is a rare weekend.

The collection of books in the library has been read by Luo Zixin day and night, and the fresh information that can be brought to him is getting less and less. Some books on computers have been read by him more than once. I studied mathematics books by myself for a while, and after I figured out some algorithms thoroughly, I changed to computer books and took out a notebook to write down my understanding and ideas.

The collection of books here does not involve cutting-edge computer knowledge, and what Luo Zixin is doing now is to use what he knows and add his own understanding, whether intentionally or unintentionally, to calculate, transform, and even innovate.This kind of behavior is similar to learning the cooking methods of several ingredients, constantly trying to cook various dishes, and even boldly incorporating your own creativity to develop new recipes.

Luo Zixin put down the "Computer Hardware" in his hand, closed his eyes and rubbed the acupuncture points on the bridge of his nose. This book was most closely related to the electrical engineering knowledge he had learned in the past. It introduced the functions of various parts of the computer. It involved some knowledge of man-machine control, and it had been read no less than five or six times by the young borrower, and the boy already knew the structure of the computer like the back of his hand, and he could memorize it fluently.

Wait, you know... like the palm of your hand?

Zi Xin straightened her back with a "shua" and licked her lips.It was only half a day away from the computer, but it seemed like years to Luo Zixin, which made the boy deeply realize that he may no longer be able to do without the computer, and he knows the structure of the computer so well... In this case, he, Can I assemble one myself?

Do whatever comes to mind.Luo Zixin spread out his notebook and "Computer Hardware" and drew out the various hardware modules in his mind. He knew that with his limited materials and tools, it would be difficult to create a computer with the same functions as the Apple 2, which was made with high-end equipment. It is a comparable machine, but it can be replaced by other parts that are relatively easy to find. The integrated chip process inside the Apple 2 is difficult, and it can also be replaced with scattered transistors, which will increase the size of the machine. Many, the functions are simplified geometrically, but——

Luo Zixin held the pen and calculated quickly. If he planned with reference to all his conditions, maybe he could build a "subcomputer" similar to a computer. Coupled with his subsequent numerical control programming for it, it should be able to make it have the power of a computer. Part of the function!

For a hungry person who is about to starve to death, even if there are no delicacies, only a few meat buns are placed in front of him, which is enough for him to rejoice.
