Bit Mania [Hacking]

The action plan with Linux is actually very simple. The kernel of the operating system manages basic affairs such as resource supply and demand, input and output devices, network and file system. Although it is decided to let go of most peripheral projects, there are still many necessary things. First set the framework together, then divide the work to do the modules that you are good at, and then exchange and debug with each other after completion. After all, sometimes one person lacks consideration when doing things, so two people check each other's imperfect design and try to achieve the best. .

Build a city and open it to everyone for free, even the land rent is not charged. Whether Linux is a fool or not, perhaps only after the system is successfully released and put into practice can we know.

Zixin's hardware foundation can be said to be comparable to almost no one, except for his teacher——Song Yubai, who personally participated in the development of Huaguo's first supercomputer, can give him some pointers. Although Linux's ability is rare and comprehensive, it is still inferior in terms of hardware. Of course, most computer talents are more inclined to software, while hardware is often the world of physics experts.So Linux took the initiative to write software, and handed over the human-computer interaction to Zixin.

At the same time, although the source code is going to be completely open, in this way, the security of the system is more important and more difficult. To put it bluntly, if everyone knows the source code, then it will be easier to analyze the loopholes of this system There are many, so it must be impeccable in the algorithm, and the code is put there for you to see, and you can't find the weakness.

This is the task of a mathematician like Zheng Xiu. Algorithms determine the precision of programs. Mathematicians can become excellent cryptography experts after consciously recharging. Zheng Xiu was clearly trained by someone in his previous life. At this time, let them Algorithm support and security issues are provided, but it looks good. The original framed program is filled with vigorous flesh and blood, and the overall level has been completely raised by several grades. The layout is comparable to the world's top operating systems. Zixin reckoned that if the decryption of the BIOS chip was left to him, one person would be enough according to the level of cultivation, and the time would be much less than that in Quhai University.

"...This is simply the most cost-effective buy one get one free I've ever seen!" Looking at the mathematical model given by Zheng Xiu, Linux sniffed and sucked half of the snot back into his nasal cavity: "Please allow me to express my best wishes to you." With the highest respect, I cordially call you, big brother!"

Octo: I'm still a junior high school student, where is Isr?

Isreal: Me too.

Linux: ...all of you are called junior high school students, so I am a primary school student!

Octo: Really? !

The days went by in the busyness of the three of them. The operating system of the personal computer was completely incomparable with the scale that Zixin wrote for LASER at the beginning, but he had experience in this field after all. Although the difficulty was greatly increased, it was still It's not that I'm not incompetent, I put in the time every day, and the progress is also remarkable.

September 9, Monday, the second day of junior high school.

Sitting in the south-facing classroom, the voice of the teacher explaining, the voice of the students reading aloud, the whispering of the young couple at the back table, the summer sun shines in, and the curtains are drawn because it is too dazzling, junior high school The curtains are light blue thin cloth, the blackout effect is not satisfactory, a gust of wind blows, but it is easy to float towards the room, covering the sight and the books on the desk, the boy folded a corner of the curtain twice , Wrapped on the latch of the window sill, pressed tightly with the iron latch, the world is finally clean.

The sound of birds flapping their wings is far and near. A group of white pigeons are parked on the roof of the opposite house. The distance between the house and the teaching building is very close. Whether the pigeons turn their heads or jump on the roof, they can be clearly seen, as if You can hear the gurgling sound.

He thought of the big fat pigeon that inspired him, maybe it was the one that changed his life drastically in the past few months, but it still seemed to be sitting here unchanged, at least his mentality was not the same as before.I have seen all kinds of people and things through the Internet, and I can understand things that were unimaginable in the past through special channels.The tall boy at the same table is still worrying about a pair of two pairs of sneakers. He doesn't know that this quiet peer beside him has changed the whole world by clapping and applauding without his realizing it.

Out of sight, a black three-box car detours along the Panshan Highway. The town flows into the sea and becomes a piece of blue.

In the back seat of this car, the fluorescent light of the computer screen we are familiar with illuminates a weathered face. It is a large white square box, nearly twenty inches wide and fifteen centimeters thick, very It looked bulky, and was placed on the lap of an old man. A plug-in cable was connected to the car power supply, and the sound of typing filled the small space in the car.

——This turned out to be a laptop computer that was really rare at the time.

The driver was a man in his early thirties, who looked a little ridiculous now but had his head parted in the middle of the 90s fashion, wearing a pair of gold-rimmed glasses, a white shirt, suit pants, the neckline was buttoned to the second button, and between his brows was Compared with the one in the back row, the academic spirit that can only be possessed by receiving higher education is young enough.He turned the steering wheel in his hand and circled the road, asking, "Teacher, what are you doing?"

The old man operating the computer in the back row didn't raise his head. He was staring at the computer screen for a long time. After a long time, he suddenly asked, but the content was a bit confusing: "Xiao Yao, do you believe in Taohuayuan..."

"Why do you ask this suddenly?" The man called Xiao Yao smiled: "The famous allusion, I have always yearned for it... But it shouldn't exist in reality... Even if it exists, it should be in that remote mountain valley ditch."

After a pause, he suddenly widened his eyes: "Teacher, when you mention this now, do you mean... Huanjiang Town?"

"You can always quickly understand other people's thoughts," the old man finally raised his head, and turned the computer on his lap to face the person in front: "Look."

He stopped the car: "This is..."

"Foreign websites."

"...So, so we are on the Internet now?!" Yao Yizhi finally saw the expression on the other party's face, it was full of surprise.

The old man said: "That's right! In Huanjiang Town, we can connect to the Internet—or via wireless router!"

After the voice fell, the car fell into silence. The young man stared blankly through the car window and looked towards the town below the winding mountain road. The ship's horn sounded faintly, and he murmured inconceivably: "Such a powerful The signal...is still on the mountainside where it is easiest to block the signal..."

"As long as you step into this area, you can connect to the Internet through wireless routing equipment anytime, anywhere—isn't this Taoyuan? I have always dreamed that Huaguo can have it, the Taoyuan of computers!... The letter that Lao Song sent to Beijing Write it, it looks like it's all true!..."

After an unknown period of time, the car on the Panshan Highway started up again, and the bumpy road caused the car to bump from time to time. However, its speed to Huanjiang Town was twice as fast as before...

The large group of rays of the setting sun sprinkled on the earth, the hot fireball is not so dazzling only at this time, the shadow of the person is stretched long, and the iron gate of the mansion folds it into a ninety-degree angle, the black The car parked at the door, and a young scholar in his early thirties stepped out of the driver's seat. His shirt sleeves were rolled up to his elbows. He trotted around to the other side of the mobility tool, opened the door, and bent over to support a thin The old man stepped out of the car, then took out another large white suitcase from the back seat, and held it in his hand.

The old man wore a pair of glasses on the bridge of his nose, and he was meticulous in his clothes, beard and hair. The young man walked to the iron gate and raised his hand to ring the doorbell.

There was a reply from inside, and the door was opened shortly afterwards. A young man was taken aback when he saw the two visitors, and then said respectfully: "I didn't expect Mr. Mu and Mr. Yao to come, so I'll go and inform my tutor."

"There is no need to notify." Yao Yizhi handed the laptop to the student who opened the door.

Mr. Song Yubai had already walked out of the yard, hugged Mr. Mu, and the two old men had a good meal, crying and laughing.

"I really didn't expect to see you in my lifetime, old man Mu Yun!"

"What!"

Yao Yizhi walked up, bowed to one of them: "Hello, Mr. Song," and patted the other: "I'm going to park the car."

"I just want to say that you still miss us in your heart, and you were really surprised when you retreated," Mu Yun said with emotion, "So you hid here secretly and tossed about, if it weren't for this time The problem is getting big, are you going to hide it from us for the rest of your life?"

Song Yubai rubbed his nose: "I'm wronged, I really lived in seclusion in the mountains and forests, I don't know anything, and someone else did something like occupying official authority."

"Who else could it be if it wasn't you?!"

"My apprentice."

"...The entire Huanjiang Town is covered by the entire network for a hundred miles... Can your apprentice do this? Which one? Zhang Yao who is working in the Chinese Academy of Sciences now? Lu Zhixiong? Bai Xiaojie?"

"Not at all." Old man Song spread his hands: "I guess he will be out of school soon, and you will see him in a while."

"After school?" Mu Yun was stunned, counting with his fingers: "There are three universities near here, the best is Quhai, so you teach in 985 college... Your apprentice may have a common language with Xiao Yao... ..."

Halfway through the conversation, the old man felt that the atmosphere was not right, and when he looked up, he found that Song Yubai and the others around him were all smiling, not good people no matter what.

At this time, the sound of the iron door being pulled creaked. When Mr. Mu turned his head, the first thing he saw was Yao Yizhi's straight figure, and there seemed to be someone behind him. Yao blocked most of the way, the two of them were talking while walking into the courtyard, the man came out from behind Yao Yizhi, and he saw clearly that it was a little boy who looked like a junior high school student.

The old man turned his neck joint by joint: "...is the grandson this old?"

"No, he is the chief engineer."
