(New book period, ask for flowers, ask for collection!) When Xiao Yuan and the three of them came to the computer room, Liu Dong was already waiting inside, he was the only one in the computer room, the computer room was very quiet, except for the slight hum of the fan in the computer case, and the crackling keyboard sound, no other sound could be heard.

"Liu Dong, the two of them come to the computer room to play for a while, don't mind." Xiao Yuan consulted Liu Dong's opinion.

"It's okay, let them find the machine by themselves, open it and play, you come here, I'll give you the development documents for downloading the software, you can take a look at it first." Liu Dong said.

Jiang Hua was not interested in any technical documents, so he found a computer that looked relatively new, sat down and opened it to play, but the little fat man followed Xiao Yuan to Liu Dong's side, obviously more interested in the technical documents he said.

Liu Dong glanced at the little fat man, did not speak, took out a thick printed material from the bag placed on the side, handed it to Xiao Yuan, and said, "You can take a look first, if you have any questions, you can ask me." ”

"Why do you want to study computer technology?" The little fat man suddenly asked after Xiao Yuan took the materials.

Liu Dong was slightly stunned, a little puzzled why this chubby guy asked this question, but he still smiled indifferently and said, "Because I'm interested." ”

"Oh." The little fat man suddenly realized, then turned his head and asked Xiao Yuandao, "He is interested in learning computer technology, so he is a hacker, right?" ”

"Oh, sort of." Xiao Yuan said with a slight smile.

"No, I'm not a hacker because I'm not interested in hacking into other people's computers." Liu Dong categorically denied that he was a hacker.

"Haha!" The little fat man suddenly laughed loudly, squeezed his eyebrows at Liu Dong for a while, danced with his hands, startled Liu Dong, his body couldn't help but lean back, his brows furrowed, and at the same time looked at Xiao Yuan on the side, with an inquiring look on his face, obviously not knowing what this little fat man wanted to do.

"Wang Yixing, are you normal?" Xiao Yuan was speechless at the little fat man's startled performance, and hurriedly said.

"Oh." The little fat man's expression was really a little normal, but it didn't last for three seconds, and his eyebrows danced again, and he turned his head to Xiao Yuan and said, "Xiao Yuan, it turns out that Liu Dong is the same as most people, thinking that hackers are people who specialize in sabotage." ”

"What is a hacker?" Listening to the little fat man's words, Liu Dong became interested, frowned and asked.

"Xiao Yuan, do you want me to explain it to him?" The little fat man asked.

"Explain." Xiao Yuan said.

"Oh yes." The little fat man cheered, then raised his chin high and said, "Hacker is actually the transliteration of hacker in English, so it can't be called a white guest, let alone a blue, green, blue and purple other color guest, hacker originally refers to a person who is interested in a certain field, and spontaneously researches and explores, so that he can have very superb skills in this field......"

"Wow, thin classmate, your memory is very perverted, you actually memorized Xiao Yuan's words word for word." Jiang Hua screamed in surprise.

Xiao Yuan was also a little surprised, this little fat man has such a good memory, and he is really not an ordinary person.

"That's what you think hackers?" Liu Dong asked, but the target was Xiao Yuan, it was obvious that the little fat man was just retelling Xiao Yuan's opinion.

"Yes, that's what hacking really means, as long as you're learning and delving into computer technology for a hobby and nothing else, then you can call yourself a hacker." Xiao Yuan said.

"Heh, it seems that I need to have a deeper understanding of the origin of the word hacker, forget it, let's not discuss this issue, Xiao Yuan, you can take a look at the technical documentation first, we are very short on time." Liu Dong smiled indifferently, and did not dwell too much on this issue, but told Xiao Yuandao again.

"Okay, I'll take a look first." Xiao Yuan nodded, found a seat and sat down, opened the document and looked at it, and the little fat man saw that everyone was not interested in talking to him, so he quieted down for a while, found a computer, opened it and crackled on it.

Xiao Yuan raised his head, a little curious about what the little fat man was doing again, so he walked over to take a look, but saw the little fat man typing some code on the computer, using the classic turbopascal environment, so he asked: "Wang Yixing, what language programming do you know?" ”

"I use pascal and basic." The little fat man said.

"Do you know how to use C?" Xiao Yuan asked again.

"No, I want to learn, but I haven't had time to learn, the computer teacher at the school said that at the beginning of learning computer programming, it is best to learn Pascal first, so that you can develop good programming habits, and the C language is too free, not suitable for beginners." The little fat man said again.

"Hehe, that's the truth." Xiao Yuan smiled indifferently and said, Pascal language because of its very rigorous structure, it is indeed conducive to the formation of programming habits, but for some programming masters, Pascal is too rigorous, most of them are unwilling to use, of course, this is not to say that Pascal language is not powerful enough, in fact, most of the tasks that can be completed by C language, Pascal can also be completed, even if C language is good at the underlying operations, Pascal can also be completed through inline assembly and other methods.

After chatting with the little fat man for a while, Xiao Yuan returned to his seat and concentrated on reading the document.

Liu Dong took out a complete document for the development of the downloaded software, from the system architecture of the entire software, to the implementation of some of the key algorithms, Xiao Yuan first took a look at the system architecture of the software, and then asked Liu Dong for a pen, after asking for his consent, he sketched on it, and then turned to the most important part behind, the downloaded multi-threaded scheduling algorithm.

Looking at the multi-threaded scheduling algorithm designed by Liu Dong, Xiao Yuan's evaluation of this guy couldn't help but be a few points higher, putting aside the algorithm idea of using the point-to-point protocol to accelerate the download like Thunderbolt in later generations, simply considering multi-threaded download, this algorithm is already quite good, of course, compared to the download algorithm that can make the ultimate use of bandwidth in later generations, there is still a lot that can be improved, but Xiao Yuan does not plan to improve this algorithm.

Xiao Yuan spent an hour reading the entire document twice, then stood up, came to Liu Dong, and said, "I've finished reading it." ”

"What's the problem?" Liu Dong raised his head and asked.

"I have marked the problems on the document, mainly because the system structure I think can be clearer, reduce the coupling degree between modules, and help us divide labor and cooperation." Xiao Yuan said, and at the same time handed the document to Liu Dong.

Liu Dong took the document, opened it and looked at it, glanced up at Xiao Yuan in some surprise, and said, "Just follow your revisions, let's divide the labor and we can work." ”

"Okay." Xiao Yuan was not polite, pulled a chair and sat next to Liu Dong, and discussed the division of software with him.

In a bathing center in Xizixiang, Nanzhou City, Chi Xiang was lying on a bed in a large shape, covered with a white towel, and his eyes were slightly closed, as if he was still reminiscing about the bone-eroding comfort brought to him by Tian'er, as well as the feeling of extreme relaxation afterwards.

There was a sound of footsteps, Chi Xiang opened his eyes, saw that it was Zhang Xiaolong, closed his eyes again, and said, "Sit down." ”

Zhang Xiaolong sat on a chair next to Chi Xiang's bed and said softly: "Brother Xiang, rest well, I'll take you out to eat, my eldest brother said that he would wash the dust and catch the wind for you." ”

"Well, I want to meet your big brother too." Chi Xiang sat up from the bed and said.
