Reborn Hacker

The matter of He Ran's identity ended just like that with Qi Zhanhang's indifferent attitude of analysis.

He Ran didn't bother to entangle any more, the matter has basically been resolved by now, anyway, he will directly name Joe and the Transcendence as one person.As for that guy's reaction, why do you think, it doesn't matter, it's not because I want to enter your company and sign a contract.snort.

At this time, it was almost time for the labyrinth network to self-destruct.A notepad file suddenly popped up on the desktop, writing: Maze Feedback Information.

Open the notepad, the information recorded in it is mainly the various operations of the three first-class hackers (He Ran still thinks so).He Ran reads very quickly. During the pull-down process of the progress bar, there are almost 20 lines at a glance. This is also practiced after reading too much source code.

When he saw about 60%, He Ran showed a slightly surprised expression on his face: "Is there such a function? It seems worth developing."

Yes, although the operation data of the three hackers that He Ran saw in the second half were small, they had indeed improved.

"Make up a labyrinth for assessment... um..." He Ran shook his head.Originally, He Ran thought of the assessment as compiling a set of test questions by himself, putting them in the CHAT for them to do, and then correcting them by themselves, or giving them a question and asking them to use what they learned to write a program based on the question.

But now what I think of is to simply make up a huge maze, set up 9 exits, and the difficulty of each exit increases from 1 to 9. This not only tests the examinee's programming ability and adaptability, The ability to solve problems also tested the unpredictable luck.

Although luck has always been thought to be invisible and intangible, He Ran always feels that luck is also the key to a hacker's growth.

From He Ran's own point of view, it was a small opportunity for him to want to become a hacker. He became a first-class hacker later (He Ran thinks) because of an intrusion into an expert's computer and then triggered his own pursuit of further computer science. The pursuit of technology.As a result, he gradually became a first-class hacker in the pursuit of technology.

Now, it is luck that ghost hands, thugs, monks, Taoists, and hermits can learn some future technologies before many people. Although it is an unfounded guess, why do you think that maybe there is such a thing as fate.

"Maze, well, we can make a portal here. If there is an encryption test over there, then there is..." He Ran started the compilation of the labyrinth network with great interest.

Qi Zhanhang's hand holding the notebook trembled invisibly. If these plans were followed, all participants would die miserably.

"Zhanhang, the group of people you learned first can take the test after I finish editing, and I can just collect the data." He Ran said sideways.

Qi Zhanhang calmly put the book on the computer desk, and pressed his hand on the book by the way: "We who learn first also need the test?"

"Well, because I still don't know the specific situation of your studies. After the test results come out, I plan to make study plans according to your own strengths and weaknesses. You have already laid a solid foundation for the foundation, but the things you learn later will be due to practice. The relationship is not enough and the relationship is not well mastered. The maze can be regarded as exercise in addition to the test." He Ran retracted his body and continued to write the program.

"Ah, right. You have to learn fault-tolerant technology first. Otherwise, the punishment in the maze will definitely crash your computer. And it's time for you to use the Unix operating system." He Ran thought of putting some small viruses in the maze Class, only to think of fault-tolerant technology.I also thought that the people who can participate in the maze test are also people who already have certain skills, and the Unix system should enter their lives.He Ran doesn't use the Unix system at present, mainly because he can directly refer to the process of operating under the win95 and DOS systems when teaching, which makes it easier to explain.If it is true, He Ran naturally prefers the Unix operating system. Of course, the advantages and disadvantages of the Unix operating system are also obvious.

The advantages of Unix are: it is a truly open operating system, the open source community shortens the waiting period for bug fixes and security patches to days or even hours, and there are continuously increasing resources.Most system applications work with text data, and text is a friendly, versatile, and highly portable form of data that can be manipulated with many utilities.Of course, there are some other less obvious advantages, in short, these provide the greatest convenience for those hackers who like to play with the system.

But in a general sense, its shortcomings are also there. In a UNIX review meeting at the USENIX conference in January 1987, RitChie analyzed many of the shortcomings of UNIX [Ritc1].Although UNIX is an excellent operating system, most users don't need an operating system, they just need a system that can accomplish a specific task.In Ritchie's words, "UNIX is simple and consistent, but only a genius (or at least a programmer) can appreciate its simplicity." "To a certain extent, UNIX is also a victim of its own successful development. Its simple license License terms and portability allowed for its uncontrollable development and proliferation."

Although it is only a shortcoming for most people, it is precisely one of the biggest advantages for people like He Ran.

These defects of Unix are more harmful to enterprises, but to individual users, their harm is much smaller, and even many hackers can directly use the programs written by themselves with better hardware configuration to reduce these shortcomings Impact.When He Ran proposed to use the Unix operating system, it was absolutely beneficial and harmless to Qi Zhanhang and the others.

"I've been wondering when will you talk about this issue." Qi Zhanhang smiled at this time.

"What do you mean?" He Ran was puzzled.

Qi Zhanhang explained: "Actually, when teaching the thugs, they were very uncomfortable at first, because we used WIN95 and DOS to operate, and they used Unix at the beginning. But in order to cooperate with our teaching, we switched to Start using the WIN operating system."

"That's fine, just think of it as the price paid for laying the foundation. No wonder the thugs were so easily captured by hackers at that time, probably because they were not used to using the WIN system, and probably didn't even get patches or anything." He Ran held his chin, "Since you have used the Unix operating system, you should know about it. Just tell them, and I don't need to explain."

"At that time, you used the WIN system to teach us, were you accommodating Xu Tao and me?" Qi Zhanhang asked.

"Why do you think so?" He Ran smiled, "At that time, most people had just been exposed to computers, and they were not familiar with many things about computers, but the win system can indeed make people familiar with it in the fastest time. Various basic operations of computers. If I let you use Unix directly, how many people do you think can maintain their enthusiasm for learning computer technology?"

"No matter what you do, the order from easy to difficult will not scare away interested people at the beginning."

Why does it sound like you've been kidnapped?Qi Zhanhang thought speechlessly.

Class 11 of C High School.

"He Ran! He Ran! Ask for foreign aid~~~~" Liu Haoyuan rushed in from outside the classroom.

He Ran didn't do chemistry today, but was reading notes.

"What asks me to be a foreign aid?"

Liu Haoyuan bowed his waist and panted for a while before continuing: "At first we had a good discussion on the topic, but I don't know who talked about "Warcraft", and Ji Wenfeng quarreled with other people."

"If there is a quarrel, just let them stop arguing." He Ran didn't understand.

"It's not like you don't know the two brothers' deep love for "Warcraft", how can we mediate it." Liu Haoyuan was anxious.

He Ran: "I can't help it..."

Liu Haoyuan: "Those two guys only admire your skills...so Zhang Sai asked me to come back and ask for foreign aid."

He Ran: "Then what are they arguing about?"

Liu Haoyuan: "There was a fight over the version and tactics of "Warcraft 2"."

He Ran: "Understood, go and tell Ji Yunfeng that "Warcraft 2" is also a series, and the tactics of different race maps in a series are different, there is nothing to make a fuss about, just practice it and you will know."

Liu Haoyuan (eyes wide open): "Is it that simple?"

He Ran: "What else do you want?"

Liu Haoyuan quickly ran back to mediate.

"I don't even know if "Warcraft 2" is out yet." Qi Zhanhang said.

"You've been working on computer technology recently, how could you care about these things?"

Nodding, Qi Zhanhang agreed, and he is indeed more interested in computer technology now.

"However, since 2 has come out, why didn't Aiden (cousin Qi Zhanhang) come to me?" Threatening to beat him in Warcraft 2.

At this time, Aiden, who was practicing battle skills in country M, suddenly sneezed: "That brat Qi Zhanhang must be thinking about fighting with me. Just wait! Hmph."

"By the way, why didn't you not play?" Qi Zhanhang asked again.

"Me?" He Ran replied lazily, "Brother Chen also needs to keep up with the times, we always use him to surf the Internet for free, so of course I have to take care of his business a little bit more. That's why "Warcraft 2" just came out. I told Brother Chen that I also collected the follow-up information, how could I not know about it. Speaking of playing, anyway, I believe that the future series will have greater playability, and I have no idea of ​​playing for the time being. , and I've been very busy recently, so let's do this first."

Qi Zhanhang also felt that he was really busy recently, especially busy, so he didn't say anything more.

The author has something to say:

Small information:

UNIX is a powerful multi-user and multi-tasking operating system that supports multiple processor architectures. According to the classification of the operating system, it belongs to the time-sharing operating system. It was first developed by Ken Thompson, Dennis Ritchie and Douglas McIlroy at AT&T Bell Labs in 1969. .
