The evening ranking has been changed to tomorrow~

********************************

At the door of the library, Liu Yueshuang found Han Feng.

"Xiaoshuangzi, what's wrong, has the computer problem been solved?"

Liu Yueshuang nodded and said, "Well, fortunately there is Du Shaofeng here today, otherwise today's registration will definitely be in vain." ”

"Du Shaofeng is also from the computer department, right?"

"yes, by the way, you don't know him. He's the vice president of our computer club, a junior, and he's very skilled, and I've heard that he's still a hacker. ”

Hacker?

Han Feng smiled and asked, "How did you meet?"

"I met in the computer club.,I applied to the computer club last year.,He's the president.,Because there is more homework in the junior year.,So I retired.,And recommended me to be the president.,Now although he's nominally the vice president.,In fact, he doesn't care about things.。 ”

Hehe, interesting! Han Feng remembered the IP address he had just traced.

Bypassing a layer of proxy, Han Feng finally determined the actual IP of the invasion, but he didn't expect it to be inside the campus network, and found a topology map of the network structure from the website of the school network center, and determined the actual address of the IP he found according to the above IP range, which is owned by the junior boys' dormitory.

Han Feng went straight to the point and asked, "Little Shuangzi, is he Du Shaofeng chasing you?"

"Huh?" Liu Yueshuang was stunned for a moment, and then asked, "How do you know?"

Han Feng smiled but did not answer.

Liu Yueshuang seemed to understand something, and hurriedly explained: "Little madman, don't get me wrong, he is indeed chasing me, but I didn't agree." He asked me out several times, but I refused, and once I couldn't say yes, but in the end I let him go. You have to believe me, I'm really not interesting to him. ”

"Okay, why are you so nervous, I'm just asking, you're so beautiful, it's not normal if no one chases you. Han Feng smiled bitterly, "You don't need to explain so much to me, really, I'm not your boyfriend." ”

Liu Yueshuang still showed joy on his face at the beginning, but when he heard the smile behind him, he froze, he glanced at Han Feng complicatedly, and did not speak again.

The atmosphere at the scene was silent for a while, Liu Yueshuang became silent, and Han Feng didn't have many words, and said a few jokes dryly, but the scene was cold.

Han Feng was not a person who talked a lot, and when he saw that Liu Yueshuang's mood suddenly seemed to be inexplicably bad, he didn't know how to comfort him, so he simply didn't speak.

The two walked silently for a while, and Liu Yueshuang suddenly said: "Little madman, your admission procedures have also been completed, you can go back first, I still have things to do in my school, so I won't accompany you to visit the campus." ”

"Oh, okay, if you have something to do, just go and get busy first, you don't need to accompany me, I'll go around by myself. ”

When Liu Yueshuang heard this, she stomped her foot very depressedly, and then left.

Han Feng felt a little inexplicable, thinking about it, he didn't find anything to make her angry, shook his head, and simply didn't care, her departure made him feel easy, because he still had something to do.

After leaving Mizuki University, Han Feng found an Internet café nearby, and then picked a more remote seat.

This is the first time Han Feng has entered an Internet café since his rebirth, except for the time in the library today, it is also the first time he has officially surfed the Internet.

Although almost every family now has a computer, the Internet café, a product with Chinese characteristics, still shows strong vitality, especially near major universities, Internet cafes are still popular with students.

In his previous life, as a hacker who often dealt with the Internet, Han Feng naturally had a lot of property on the Internet, whether at home or abroad, he had an online banking account, which was known only to him, and others could not find out at all. Of course, there are also public accounts in the name of Yue Feng, but Han Feng does not plan to touch those accounts.

What he has to do now is buy a laptop online and debit the money directly from one of his e-bank accounts.

Han Feng counted it, and now he can use about three million US dollars, most of which is earned by doing security checks or writing vulnerability patches for foreigners in his previous life, as well as engaging in some such as domain name investment, no one else knows, although it is not a lot, but compared to him now, this is also a lot of money, at least in the early stage, it can meet some of his needs, as for the later stage, he is not worried, as long as he improves the system in his brain, making money is not a problem at all。

Han Feng picked a Lenovo notebook with a mainstream configuration, the processor is quad-core*bit, the memory is DDR3rd generation 4G, and the graphics card is integrated, but the performance of the integrated graphics card at this time is equivalent to the top independent graphics card twenty years ago, the display is touch, and the hard disk is 0.5T(1T=1024G)...... It was cheap, it only cost him a little more than a thousand dollars in total. Although he has the conditions to choose a higher-end configuration, but in that case, it will be too arrogant and inconsistent with his current style of doing things, and he has to keep a low profile now.

Transfer the account directly from the Internet, fill in the information, and the other party will deliver the goods directly to your door.

Five minutes later, the other party called to confirm, and after Han Feng confirmed, he said that it would be delivered within two hours, and asked Han Feng to wait at his residence.

"The quality of service has improved a lot. Muttered, Han Feng got off the plane to check out.

After returning to the residence, less than an hour, the notebook was delivered, unpacked in person, and then assembled, the technician wanted to help Han Feng install the system, but was rejected by Han Feng, this thing, he can do it himself, in addition, he also has to install multiple systems, just when shopping online, he ordered several genuine operating systems together, including Windows2010, Linux.

The place where Han Feng lives has opened a wireless network, and the laptop can be directly wireless, but Han Feng is not in a hurry to go online, he now has an important problem to solve - his hands.

Now, Han Feng can only flexibly control his index finger and thumb for a total of four fingers, before, without manipulating complex things, these four fingers were enough to meet the needs, but now, if you want to type, these four fingers are obviously not enough.

"It looks like it's time to rewrite the controller driver. Han Feng said to himself.

Writing a control program for your finger is actually the same as writing a driver for some devices in the operating system, only when the driver is written well and provides a variety of basic operations, can you control the device well. The same is true of Han Feng's super system, if you want to fully control your hands, you must upgrade your own hand controller.

Because the hand control driver written before,It's just written for emergency purposes.,In the design,It's very rough to consider.,Only encapsulate some of the main control signals.,So it's very weird to move.,It's a little hard like a zombie.,And it's so simple that it only controls four fingers.。

This time, Han Feng decided to redesign it to make his hands as flexible as possible, so this time, he planned to package the control signals of his entire hands into a single driver, from his arm to his fingers.

After dinner, Han Feng began to write a "hand control driver" in his brain.

The activity of programming happens directly inside the brain and body, so on the surface, Han Feng just lay quietly in bed and did nothing.

In reality, the process is extremely complex and cumbersome.

First of all, he had to sort out all the signals that control his hands, but there are too many nerve signals involved in one hand, not only related to the central nervous system such as the brain and spinal cord, but also involving sensory nerves, motor nerves and motor systems...... Wait a minute.

The previous measure taken by Han Feng was to focus only on the main and necessary signals and ignore those that are insignificant.

What are the main signals?

Now the first problem is to make his hands move flexibly, so the main signals are those signals that control the muscles and bones, and the signals related to the pain nerve are completely ignored, of course, some relatively slight tactile signals must be retained, otherwise when hitting the keyboard, there is no feeling at all.

Fortunately, Han Feng had already spent a lot of time figuring out the specific meaning of these signals, otherwise, he estimated that it would take at least half a year to complete this "manual driver".

However, Han Feng still thought about this driver too simply, although it only left about 30% of the main signal, but it had already made him a little dizzy, and the organization was relatively clear at the beginning, but later, he felt that his brain was very tired and a little out of control.

To his relief, though, he was finally done, and it took him a whole day and a night to do it, and in the middle of it, he only ate once and drank some water.

To upgrade the manual driver, first uninstall the old driver, and then install the newly written program, and during the time when the old program was uninstalled, his hands are completely immobile, this situation, as if returning to the previous paralysis.

Then, it took Han Feng half an hour to finally install the new control drive, but then he vomited blood and found that the new drive did not work at all.

In fact, he has often encountered this kind of problem before, programming, it is normal to encounter bugs, but what makes Han Feng feel depressed is that he has checked it several times, but he still hasn't found out where the problem is.

"God, don't play me like that. ”

Han Feng was too confident in himself, and he didn't back up the previous driver at all, that is, if he couldn't solve this problem, there were only two options, either let his hand continue to be paralyzed until he fixed the bug, or rewrite the old driver before and still only control four fingers.

This new manual driver is extremely complex, after strict layers of packaging, and Han Feng does not have any debugging tools, so it is a very large project to find an unknown BUG from it.

After holding on for a while, I still didn't find the BUG.

“…… No matter, let's get some sleep first. ”

Han Feng really didn't have the energy to continue now, so he had to carry two dangling hands, ran to the hall, ate some compressed biscuits randomly, and then fell asleep on the bed.
