Bit Mania [Hacking]

In October 1991, with the release of the first Linux kernel version 10, the wave of liberalism in the software world finally came to the fore.

FSF (Free Software Foundation) was founded in October 1985, and it has been exactly six years since then. The founder Roger has devoted half his life to the open source software movement. The number of members of the foundation is actually quite large.Speaking of which, writing software is not difficult, three lines of code, a little packaging can become a simple software, but the problem lies in the system.The system is the stage where the program runs and the soul of the computer. Its engineering volume is not trivial, and talents who can write it are hard to come by. The software developed by freelancers in the past is still based on the charging system. It also makes free software a vassal of those systems, a kind of bubble-like tasteless existence-in the final analysis, all of this is just a lack of Dongfeng, and Dongfeng is an equally free system that can carry these software.

Now, Linux developers join hands with FSF to help the giant's baby start toddler.How many sleepless nights of espresso, the raging fire when the building is burning, the gray and black exhaust of the car, the rapid and delayed telephone ringing, the red lips and guns on the podium, the sweat falling on the computer keyboard ...Perhaps for the people of later generations, it is just a page of historical picture album that was casually flipped through in a leisurely afternoon, but only those who have experienced it can truly understand the taste of it.

The weather is getting colder, and there is a slight but continuous north wind blowing in the capital. The leaves of ginkgo covered the campus with golden color. In December, near the end of the semester, Zixin received a letter from FSF first salary.

Considering the security of personal identity information, Roger remitted the salary after opening an account for Zixin with UBS. Swiss banks are not very popular in China, but fortunately, Zixin was able to find an office in the imperial capital.

To this, Zixin’s reaction was: You guys can really afford the wages? !

Roger: ...Indeed, our foundation has been in deficit for two and a half years, but now, we have a turning point, thanks to your system!

Octo: Say, what an unforgivable thing to do with my system!

Linux: Hey, isn’t our kernel spread on the Internet? No, there are two large game development companies using it as a jump box. After trying it for a while, I think it’s very good. They originally planned to use the Windows system. The terminal service access license and client access license that cost tens of thousands of dollars are all saved for them now, and the technical director there also called me, saying that our system requires more hardware than those large Commercial systems are lower and they thank us from the bottom of our hearts!

Octo: What does this have to do with money, you didn't take the opportunity to make a fortune, did you?

Roger: No, no, the other party decided to provide us with long-term financial sponsorship, and they allocated tens of thousands of dollars!And he also said that he would recommend us to our partners and become our sponsors together to support the operation of the team, lol!

Octo: It seems very good to hear what you said. I am not good at this kind of thing, so you can do public relations.

Roger: Leave it to me, no problem!By the way, they also asked if there are people who are proficient in Linux systems who can come to work in their company, or help improve the system?

Linux: This... is a bit difficult. Speaking of which, only Octo and I are the designers who are familiar with Linux, and then the first batch of volunteers who use this system... Where are their companies?How about going to the big room and asking if any of our volunteers are there or would like to go there?

Roger: It's a French game designer.But don't forget that there are spies in the big room, if those bastards go to other companies, it will be terrible!

Octo: That's right. Is there any way to filter out the spies?

Roger: If you check directly among everyone, not only will it be easy for people to slip away, but it may also cause dissatisfaction among the masses.

Linux: Yeah, it might feel like we don't trust them or something...

Octo: So you have to do it secretly.

Linux: how to do it?

Roger: Actually speaking, my Freedom Association is also like this. There are many people, but mixed.Now that the scale is getting bigger and bigger, one thing has been put on the agenda, and that is rectification.

There was a knock on the door behind him, Zixin answered, the door was opened, familiar footsteps approached, and a cup of hot milk was placed next to the computer.

"Thank you, Zheng Xiu." Zixin said.

"Hmm." The visitor replied with his nose, took a comic from the bookshelf, and lay down on the sofa beside him to read.

The winter afternoon sun shines into the house, and the rhombus-shaped beams of light reflect the fine particles floating in the air, bringing a cozy atmosphere that almost makes people think they can smell the aroma of baked bread.

Zheng Xiu is a person who doesn't have a strong sense of presence and doesn't talk much, but when he is by your side, he can always clearly feel a certain sense of reliability.The relationship between these days often makes Zixin feel that the two have known each other for a long time, and they have a perfect understanding with each other—maybe it's not about him, but Zheng Xiu's familiarity with him. It feels like it will make people feel close, and they will unconsciously let go of their defenses.

What a comfortable day... Zixin stretched, but her thoughts began to drift away.Speaking of which, I don't know how Qi Xingchu is doing now... Tsk, he doesn't want to live a good life, he has to go to some kind of prison... If he didn't go in, he might be thumping happily in the ocean of the Internet just like himself... Why don't you go see it today?

Octo: By the way, do you remember that Elmo?

Afier: Uh... the one that spread the worm?

Roger: Tsk tsk, why don't you remember, the world's top black hat.

Octo: Black hat?

Roger: Hmm.There are three types of hackers: black hats, gray hats, and white hats. Black hats are badass hackers who like to cause damage, and white hats are law-abiding citizens like us!

Linux: But didn't we go to MS's house to smash and rob it not long ago?

Roger: Uh...that's self-defense out of necessity!

Mild: The revolution has not yet succeeded. If we have to define our current situation, I think it should be gray hat.

Zixin tried his best to bring back the crooked topic, Octo: Is that so... I wonder how Elmo is doing now?

Vogt: More than four months have passed, and he should have been sentenced.

Octo: Do ​​you know where he is being held?

Mild: What's the matter?

Octo: I'll just ask.

Roger: That depends on who took him over...

Octo: Rhondstone Air Force Base, USA, Cyber ​​Security Command.

Afier: It's them... If that person is really a minor as the rumors say, according to the geographical location of Rhonda Stern, it is most likely that he should be sent to the local juvenile detention center in Louisiana.

Octo: You know so much!

Zixin minimized the chat room and quickly found the IP of the Louisiana juvenile detention center.Doing it by himself, with ample food and clothing, he pinched his knuckles, disappointed to find that they could not make the sound of popping beans in the legend at all, and someone put the two thin white claws back on the computer resentfully.

How could the firewall of the juvenile prison be comparable to the heavily guarded air force base, he didn't even bother to call his friend who was reading comics to help, so he sneaked in by himself after a while.

After entering, the first thing to do is to call up the prisoner's cell allocation table and find out the room where the prisoner is located.Zixin wrote a terminal emulator and opened a hole in the juvenile management office's database. After a few touches and tinkering, Qi Xingchu's location was quickly dug out by him.Juvenile detention centers generally have eight-person rooms and six-person rooms. At the two ends of the dormitory building, there will be rooms for four or even two people because of the small space.But even though it was small, he was the only one living here, and the other bed was empty, which made it look more spacious.Prisons in foreign countries are different from those in Huaguo. Even college student dormitories in Huaguo have bunk beds, but here there are only one bed and a separate bathroom.

After that, it will be easy. The life of the prisoner is under surveillance, and there are cameras everywhere. He only needs to kidnap and take pictures of the first few, and take a few glances through them, and today's goal will be achieved.

"what?"

"What's wrong?" It was Zheng Xiu's voice, propping up his upper body from the sofa.

"It's okay." Zixin shook his head, and gestured to him to get down. Out of some indescribable inertia, Zheng Rabbit immediately lay back on the sofa obediently, with his belly upturned.

Zixin turned his attention back to the computer.He found that one of the many cameras had tampered with the mapping data, and the picture that should have been captured and reported to the monitoring room was replaced with the picture of another camera. The cameras in the prison area were tampered with one by one. If Zixin hadn't discovered anomalies from the data point of view, ordinary people would really not be able to find any problems just by looking at the screen.

He followed the data structure all the way down, and found that the original source of this series of tampering behaviors was actually in Qi Xingchu's room!

This aroused someone's strong curiosity, but on second thought, after all, I sneaked in secretly and didn't want to cause trouble, so it's better not to make a big effort to change all the cameras in the entire prison back, just find the camera data at the beginning of the trip, and change it. Just come back and see what's going on.

Zixin gathered himself together, and stretched out his evil claws to the camera in Xingchu's room...

After 10 minutes, the computer screen successfully displayed the picture in the camera.

The water vapor is transpiring, and the large mirror in front of the sink is covered with a layer of gray mist. The shower above the head is continuously spraying tap water. The lens of the camera is made of breathable plastic, not ordinary glass that condenses fog in the traditional sense. , so the picture imaging is still quite clear at this time.I saw the young man standing below with his whole body naked, looking a little lazy. The water droplets gathered on his collarbone to form a shallow handful, and then slid down along his chest and streamlined muscles.

Xingchu was facing the camera sideways, with broad shoulders and narrow hips. He should have had his hair cut once when he first entered the prison, but it has grown a lot in the past few months, and the black hair sticks wetly to his face. He casually tucked it behind his ear.

Zixin didn't expect to see such a picture suddenly, he was a little dumbfounded, he was stunned for a while, and then he came back to his senses, and hurriedly cut off the connection of the camera.

The shower was turned off with one hand, Qi wiped off the water with a towel, got dressed and walked out of the bathroom, picked up the cup on the table and poured himself a glass of water.

In this place where there are no human rights at all, if he hadn't possessed some technology, I'm afraid even taking a bath would have to be seen from beginning to end.Unaware that he had been taken from beginning to end, Xingchu thought about something, took out an object from the drawer, and put it in his mouth.

Zixin gulped down the hot milk in his hand, and then felt his fragile eyes were gradually soothed. He sniffed, sat in front of the computer and thought for a while, and made a just decision - go back and put the milk that he had been held by him before. The corrected camera changes back to the original wrong picture.

Holding the poor monitor hostage again, Zixin saw that Xingchu was sitting on the bed in the dormitory with something in his mouth, a thin white one—was it a cigarette?Speaking of which, being handsome is an advantage. Not only does it not make people think that this juvenile offender is hopeless, but it gives people a cool feeling.

At this time, it seemed that someone was knocking on the door. Qi Xingchu stood up, walked over to open it, and Zixin saw a white boy walking in from the door. He seemed to be saying something to Xingchu, and the expression on his face was definitely not kind. Then that The young man raised his right hand and waved his fist to punch Xing Chu in the face.

Zixin held his breath, and was so nervous that he almost didn't cry out. Qi Xingchu lifted his leg and kicked the visitor's stomach. The white boy immediately squatted down, covering his stomach, as if he couldn't even stand up in pain. Getting up, Xing Chu lifted the man's collar and threw it out, then closed the cell door.

Sitting back on the side of the bed again, Qi raised his hand and took out the lollipop that was empty in his mouth.
