Tonight, the ranking will be changed to tomorrow~

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

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

"Xiao Shuangzi, how are you doing? Have you solved the computer problem?"

Liu Yueshuang nodded and said, "Well, fortunately Du Shaofeng is here today, otherwise the registration work today will definitely be ruined."

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

"Yes, by the way, you don't know him. He is the vice president of our computer club, a junior, and has a very good skill. I heard that he is still a hacker."

hacker?

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

"I met at the Computer Club. I signed up for the Computer Club last year. He is the president. Since he has a lot of homework in his junior year, he retired and recommended me to be the president. Now, although he is nominally the vice president, he actually doesn't care about the matter."

Haha, interesting! Han Feng remembered the IP address he just tracked down.

Bypassing the first layer of agent, Han Feng finally determined the invasion of the actual IP, but unexpectedly it was inside the campus network. He found a topology diagram of the network structure from the school network center website, and determined the actual address of the IP he found based on the IP range above, which was owned by the junior boys' dormitory.

Han Feng asked straight to the point: "Xiao Shuangzi, is his Du Shaofeng chasing you?"

"Ah?" Liu Yueshuang was stunned and asked immediately, "How do you know?"

Han Feng smiled but refused to answer.

Liu Yueshuang seemed to understand something and quickly 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. Once he really couldn't agree, but in the end I still let him go. You have to believe me, I'm really boring to him."

"Okay, why are you so nervous? I'm just asking. It's not normal for you to be so beautiful, no one chases you." Han Feng smiled bitterly, "Don't explain so much to me. Really, I'm not your boyfriend."

Liu Yueshuang's face showed joy at the beginning, but when she heard the smile behind her, she frozen. He glanced at Han Feng in confusion and didn't say anything.

The atmosphere at the scene became silent for a moment, and Liu Yueshuang became taciturn. Han Feng didn't say much, so he told a few jokes dryly, but it got cold.

Han Feng was not a person who talked a lot. When he saw Liu Yueshuang, he suddenly felt inexplicably bad, and he didn't know how to comfort him, so he simply stopped talking.

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

"Oh, okay, if you have something to do, go and do it first. No need to accompany me, I'll just take a walk by myself."

When Liu Yueshuang heard this, she stomped her feet in depression and left.

Han Feng felt a little confused. After thinking about it, he didn't find anything that made her angry. He shook his head and simply ignored it. Her departure made him feel relaxed because he had something to do.

After leaving Shuimu University, Han Feng found an Internet cafe nearby and then picked a seat that was a little more biased.

This is the first time Han Feng has entered an Internet cafe after he was reborn. In addition to the time he was in the library today, it is also the first time he has officially surfed the Internet.

Although almost every household now has computers, Internet cafes, which have Chinese characteristics, still show strong vitality, especially near major universities, Internet cafes are still popular with students.

As a hacker who often deals with the Internet in his previous life, Han Feng naturally had a lot of property on the Internet. Whether in China or abroad, he had online bank accounts. He only knew these accounts himself and could not find them out. Of course, there are also public accounts under Yue Feng's name, but Han Feng did not intend to touch those accounts.

What he has to do now is to buy a laptop online, and the money is directly transferred from one of his electronic banking accounts.

Han Feng counted and found that the funds he could use now were about three million US dollars. Most of this money was made by foreigners in his previous life, including security testing or writing vulnerability patches, and making some investments such as domain name investment. No one else knew about it. Although it was not a lot, compared to him now, it was a considerable huge sum of money. At least it could meet some of his needs in the early stage. As for the later stage, he was not worried. As long as he improved the system in his brain, making money was not a problem at all.

Han Feng chose a Lenovo laptop with mainstream configuration. The processor is quad-core * bit, the memory is DDR third-generation 4G, and the graphics card is integrated. However, the performance of the integrated graphics card at this time is equivalent to the top independent graphics card twenty years ago. The monitor is touch-type, with a hard disk of 0.5T (1T=1024G)... It's very cheap, and it only cost him more than a thousand dollars in total. Although he has the conditions to choose a higher-end configuration, it would be too arrogant in that case, which is inconsistent with his current style of dealing with things. He has to keep a low profile now.

Make a deposit directly from the Internet, fill in the information, and the other party will deliver the goods directly to the door.

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

"The service quality has been improved a lot now." After muttering, Han Feng got off the plane to check out.

After returning to his residence, the notebook was delivered within an hour. He unpacked it in person and then assembled it. The technician wanted to help Han Feng install the system, but Han Feng refused. He could handle this by himself. In addition, he also had to install multiple systems. When he was shopping online, he ordered several genuine operating systems together, including Windows 2010 and Linux.

The wireless network is already enabled where Han Feng lives, and the laptop can access the Internet directly. However, Han Feng is not in a hurry to access the Internet. He still has an important problem to solve now - his hands.

Now, Han Feng can only flexibly control his index finger and thumb, a total of four fingers. Before, he didn't have to manipulate complicated 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 seems that it's time to rewrite the controller driver." Han Feng said to himself.

Writing control programs for your fingers is actually the same as writing drivers for some devices in the operating system. Only when the driver is well written and various basic operations are provided can you control the device well. The same is true for Hanfeng's super system. If you want to fully control your hands, you must upgrade your own controller driver.

Since the manual driver I wrote before was written for emergency response, it was roughly considered during the design and only encapsulated some major control signals, it seemed very weird when it was moved, just as hard as a zombie, and so simple that it only controls four fingers.

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

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

The programming activities occur directly within the brain and body, so on the surface, Han Feng just lies quietly in the bed and does nothing.

In fact, this process is extremely complicated and cumbersome.

First of all, he had to sort out all the signals that control his hands, but there were too many nerve signals involved in one pair of hands. It was not only related to the central nervous system such as the brain, spinal cord, but also involved sensory nerves, motor nerves, and motor systems... etc.

Han Feng’s previous measures were to focus only on the main and necessary signals and ignore those irrelevant signals.

What are the main signals?

The first problem now is to allow his hands to move in a sensational way, so the main signal is to control the signals of muscles and bones. The signals related to the painful nerves are completely ignored. Of course, some relatively slight tactile signals should be retained, otherwise there will be no feeling when typing on the keyboard.

Fortunately, Han Feng had spent a lot of time to understand the specific meaning of these signals, otherwise, he would probably have to take at least the first half of a year to complete this "hand-controlled driver".

However, Han Feng still thought of this driver too simply. Although he only left the main signal of less than 30%, it made him a little dizzy. The order at the beginning was quite clear, but later on, he felt very tired and could not control it.

But what made him feel relieved was that he finally finished it. He spent a whole day and night on this. Halfway through, he only ate once and drank some water.

To upgrade the manual driver, you must first uninstall the old driver and then install the newly written program. During the period when the old program is uninstalled, his hands are completely unable to move. This situation is like returning to the past when it was paralyzed.

Then, it took Han Feng half an hour to install the new hand-control driver, but then he vomited blood and found that the new driver had no effect at all.

In fact, he often encountered such problems before. It is normal for programming to encounter bugs, but what made Han Feng feel depressed was that he checked them several times, but still did not find out where the problem was.

"God, don't fool me like this."

Han Feng was too confident in himself. He didn't backup the previous driver at all. That is to say, if he couldn't solve this problem, there were only two options, either keep his hands paralyzed until he fixed the bug, or rewrite the previous old driver and still only control four fingers.

This new manual driver is extremely complex and has been strictly encapsulated layer by layer. Moreover, Han Feng does not have any debugging tools yet, so if you want to find an unknown bug from it, this is another huge project.

After persisting for a while, I still couldn't find the bug.
