"Hello everyone, we are going to talk about macroeconomics in this class......"

After doing Dragon TV's talk show, Chen Jiayi returned to Tsinghua University to continue his classes. During this period of time, Chen Jiayi worked very hard and desperately absorbed courses on economics. Basically, if there is a well-known economics professor in another class who gives a big lecture on economics, Chen Jiayi will run to listen. Some masters like them, casually talk about economic understanding, but it is the summary of decades of experience. Compared with Chen Jiayi's own understanding, it is much clearer.

has such a good learning environment, Chen Jiayi also cherishes it. So, many times, students in the Department of Management and Economics can see a student with thick black-rimmed glasses, running back and forth between classrooms from time to time.

At the beginning, many classmates saw this student wearing such a thick black-rimmed glasses, and felt that this classmate was a little rustic. But after taking a second look, I felt that this person's words and deeds were very generous and natural, giving people a very comfortable feeling.

In this class, it is said that a professor from Peking University came to Tsinghua University to explain a lesson in friendship.

"We know that macroeconomics refers to the general activity of the national economy. Only when we understand macroeconomics can we better formulate various policies so that the national economy tends to grow normally. Of course, because in many cases. Macroeconomics is just a theoretical system, for example, we analyze how many people will lose their jobs due to a certain factor. However, it is not possible to let a factor arise in order to substantiate this one point and thus watch the change in the number of unemployed...... Therefore, this also inverts the shortcomings of the macroeconomy, and sometimes an economic crisis occurs without even knowing it. However, with the development of society, more and more problems have arisen in the economies of various countries, and we have continued to unify and make judgments, and the modern macroeconomy has been able to control the economic operation of the whole world. This also allows countries to adopt different strategies to make up for the economic crisis when it comes......"

Peking University and Tsinghua University are both among the highest universities in the country, although the level of Tsinghua University's economics and management department is stronger than that of Peking University. However, it is not necessarily much stronger. Moreover, many economics professors at Peking University are also on the same side. Chen Jiayi sat in the back row of the large classroom, and remembered the words of these economists. Repeatedly experience and slowly form your own opinions.

Unconsciously, the two friendship topics ended here, and Chen Jiayi also packed up some things and returned to the dormitory.

"Brother Qingyun, quick, go to the forum."

This forum is naturally the Mizuki Qinghua Forum.

"What, what's going on at the forum?"

There are very few classes in the university, and there are generally classes at noon and no classes in the afternoon, so there is relatively more time for students. The most important thing is that there are all kinds of vacations in college. When Chen Jiayi was in class, he was able to take care of the company's affairs on the other hand, but he didn't delay either.

"Yes, now the forum has turned upside down, but I haven't found that Chen Jiayi."

The dormitory [***] is also a person who likes to join in the fun, since the last time Chen Jiayi appeared on Dragon TV's program, Tsinghua University instantly became a sensation. As a result, there is a group of Chen Jiayi's fans. began to look for Chen Jiayi at Tsinghua University, of course, this group of students is also a high-quality person, and they have always acted in secret, and the soldiers are divided into two ways. On the one hand, this student went to various classes to investigate, and some other students were already in the Shuimu Forum to find out if there was any trace of Chen Jiayi.

It's just that they have been looking for a week, and they don't even know Chen Jiayi's shadow. There are even students who are more familiar with the leader, and the leader also said, "I really haven't found Chen Jiayi's name here." ”

All of a sudden, the entire Shuimu Forum was sighing and depressed, could it be that Chen Jiayi was a liar?

"Alas, no wonder Chen Jiayi doesn't want to show his face, how dare he come out with such a situation like yours."

"That's true, but we're just looking for him, and we're not going to eat him."

While chatting with Chen Jiayi, he said to Chen Jiayi.

At this moment, the computer of Chen Jiayi's laptop suddenly sent out an alarm, "There is a hacker." ”

"No, am I being discovered?"

Chen Jiayi frowned secretly, but he didn't move. He secretly said in his heart, "This world has not yet given birth to hackers who can hack into me, and let you come in and take a look." ”

So, Chen Jiayi made some settings for the firewall and lowered some requirements. Sure enough, the hacker entered Chen Jiayi's system. However, this system is the secret jar that Chen Jiayi prepared for these hackers. This secret pot, like a real computer, is virtual, but all data can almost reach the point of being fake.

For many hackers, this is one of the gentlest killers.

"Ok, you can't escape."

After the hacker entered Chen Jiayi's computer, Chen Jiayi tracked down the visiting IP. The first IP address was in the UK, which was obviously a springboard, and Chen Jiayi quickly cracked the other party's meat machine. And, in the case that the other party does not have a trace of investigation, it will be cracked layer by layer. After 3 consecutive drafts, Chen Jiayi finally found the IP address of the other party.

"Tsinghua University."

At first, Chen Jiayi thought it was wrong, but when he took a closer look, it was true. However, Chen Jiayi also understood that only in the IP of the same campus network could he invade himself. Otherwise, it is difficult to find your own IP.

"I wonder which hacker is so curious about me?"

Chen Jia was silent, and slowly invaded the other party's computer.

"Secret jars."

Unexpectedly, this person's skills are not bad, and he also has a closed tank system in his computer. However, for Chen Jiayi. The secret tank system that was discovered, how can it be called a secret tank? So, it was very easy to jump out of his secret jar and go directly to the other party's local server.

"I'm fork, the other party's defense is really strong enough."

As a qualified hacker, it is generally not easy to leave important information on your computer. Even if it is left, most of the content will be encrypted in a series of ways. And as soon as Chen Jia came across, he was an extremely experienced master. On the other party's computer, almost all the important content is encrypted.

Perhaps, for others, even if they hack into his computer, it may be fruitless. It's a pity that he ran into Chen Jiayi, a pervert. Since he was reborn, Chen Jiayi has countless computer information technologies in his mind. Not to mention this decryption, even if it is a more difficult 256-bit dynamic password, Chen Jiayi can also break it loosely.

Invoked a secret breaking tool, and Chen Jia cracked several important secret folders in an instant.

Originally, Chen Jiayi rarely did hacking activities like this. It's just that the other party has come to invade him. He wanted to see who this great god was. ”

"Yu Wenrou."

Female?

From a large pile of information, Chen Jiayi found the hacker's information.

Subsequently, Chen Jiayi continued to search.

"Compression algorithms."

There is a folder inside, which is full of some compression software algorithms.

Just when Chen Jiayi wanted to take a look at his compression algorithm, suddenly, the other party seemed to have discovered Chen Jiayi's existence, and immediately enabled a command and blocked many ports. Then, Chen Jiayi was directly kicked out of the opponent's computer. However, this doesn't matter to Chen Jiayi. I already know her identity, and Chen Jiayi seems to have seen this person's name somewhere.

"Lin Zi, have you heard of Yu Wenrou, how do I feel that this person is so familiar."

"Brother, of course I'm familiar with it, Yu Wenrou is the sub-version of the computer section. Let me tell you, she's a big beauty. I don't know how such a beauty can learn to use a computer. What a waste, how good it is to come to our management department. ”

At the Shuimu Tsinghua Forum, a large number of students went online, using the real-name system. Just look it up, in fact, you know.

"No wonder."

Hearing [***] explanation, Chen Jiayi then understood, and said in his heart, "No wonder it's so familiar." ”

So, Chen Jiayi entered the computer section of the Shuimu Forum and checked a few posts posted by the sub-editor, "On the algorithm of compression software." ”

The most important technology of compression software is the processing of data. And as for how to deal with it, it involves algorithms. It can be said that compression software and cryptography are the strongest disciplines in the whole computer to apply mathematics. If the compression software can come up with a powerful algorithm, then a super compression software can be developed.

This post is exactly Yuwenrou's algorithm for compression software, and put forward a good idea.

"It's a good idea."

Chen Jia took a look at it, and the compression software made according to this idea should be comparable to the more popular "winrar" compression software in the market.

"It reminds me."

Seeing this compression software, Chen Jia thought of his previous strategy.

At the beginning, Chen Jia thought of small software, and the strategy of big use was to use these necessary software to install first, and then defeat Microsoft. Looking at it now, Tang Dynasty Audiovisual has achieved good results. The Tang Dynasty guards did not start to exert their strength because they were still seizing the market. Therefore, since the Tang Dynasty Guardian was launched, it has never been advertised. Like a good baby, tell all users around the world that in fact, I am just a system management software, and I don't do bad things.

Thinking of this, Chen Jiayi didn't pay much attention to the hacker, and then he would trouble her again.

"Jiafeng, are you there?"

Chen Jiayi first contacted Lu Jiafeng of Tang Dynasty Software and got the things he just thought about first.

"Do you know anything about compression software?"

Lu Jiafeng's entire team used to make antivirus software, but those who can do antivirus software should be technically good.

"I have understood, but I haven't touched on it, mainly because the compression algorithm stumped us."

As long as the compression algorithm is handled, the compression software is actually a small piece of software.

"Well, I have a compression algorithm in mind here, you guys study it, and strive to get a new compression software in the near future......"

After speaking, Chen Jiayi sent a document to Lu Jiafeng.
