Yan Lao saw that on the manuscript paper, there were five ways to solve the problem, and there were a little more steps, with the schematic diagram, but it was clear at a glance.

The look of relief on Elder Yan's face became more and more intense, and finally, he smiled.

"What is the name of this classmate?" asked Elder Yan towards the fat teacher.

An embarrassed look appeared on the fat teacher's face, there are so many people in a class, how can everyone remember it!

Besides, besides, it occurred to him that something was wrong, although his memory was a little poor, but he had taken several classes, and it seemed that he had met this student for the first time today.

The fat teacher's look made the clever Zhang Yi take over the topic with interest: "Hello Elder Yan! My name is Zhang Yi." ”

Yan Lao let go of the fat teacher, and said to Zhang Yi with a pleasant face: "Our school will send a student with a talent in mathematics to participate in a country's project public relations team, are you willing to participate?"

Zhang Yi showed a hint of hesitation in his expression, whether this kind of research group should be closed for a period of time and not see the light of day. What about your own career, and what about your two women?

His expression did not hide from Elder Yan.

The fat teacher was also anxious, and he couldn't wait to help Zhang Yi agree immediately.

"Zhang Yi, can you tell me about any problems that are difficult to solve? Say it, and I will help you think of a way. ”

"It's nothing, Elder Yan, I have a company outside, I'm afraid that this kind of research group will not close the contact with the outside, which will cause problems in the company. ”

"Oh, you've opened a company!" Elder Yan's expression showed a hint of curiosity.

"What does the company do?" asked Elder Yan.

"Mainly engaged in computer software development. "As for cracking software and selling pirated software discs, even if they don't break the law under the current law, they don't sound good. So he didn't even mention it.

"Computer software development, what else can you do?"

Yan Lao's expression was full of shock, there are many students who start businesses, but now how many students dare to take software development as the direction of entrepreneurship, there are very few people who know about this, let alone make money-making business software.

That field can only be developed by companies like IBM, Oracle, and Microsoft. The domestic, that is, the WPS made by Qiu Bojun of Jinshan is a little famous.

The fat teacher was even more shocked and couldn't speak, this student who missed class all day was simply a demon.

In the end, he figured out what the problem was, not that he was not familiar with the student, but that he had never met the student since the beginning of the school year. There's only one explanation for that, this student has been skipping class.

"Then what software did your software company make?" asked Elder Yan immediately.

"At the moment, only a small compression software has been made. ”

Yan Lao was full of interest, pointed to the computer across the desk and said, "Can you install it on my computer?"

"Absolutely. ”

Zhang Yi turned on the computer, looked at the network and connected, and directly logged in to Sina's download area, downloaded the micro-hardware compression software, and ran it directly after decompression.

Behind him, Mr. Fat and Mr. Yan saw clearly that the compression software he downloaded ranked first in Sina's download channel, far exceeding the number of downloads of all other software.

Zhang Yi hasn't logged in to Sina for a long time, I didn't expect my compression software to rank first, I thought about it subconsciously, in fact, it's normal, the current network speed is as slow as a cow, I want to download software, or transfer software, and I can't improve the bandwidth, I can only find a way to compress the software, the compression ratio is high, and the easy-to-use micro hardware compression software will of course be favored by everyone.

Yan Lao took the mouse in Zhang Yi's hand and skillfully tried this compression software, and the compression speed and compression ratio are indeed much stronger than RAR and ZIP.

The key operation is convenient, the full Chinese operation interface, as well as the optional English interface, encryption functions, etc., all the functions he can think of, this software has, and even some special features that he did not think of, the author of this software also thought of it.

The fat teacher was itchy and wanted to try this small and delicate software, but he didn't dare to compete with Yan Lao for the computer.

You must know that the old Yan in front of him is a big bull in the mathematics world, and his protégés are all over the world, but he has no intention of pursuing a career, otherwise, he may just be a vice principal.

What's more, he is still his student. The traditional thinking of being a teacher for one day and a father for life in China is not something that anyone can change at will.

The more Yan Lao used it, the more he couldn't put it down, and he turned around and said to Zhang Yi casually: "The research group only needs to sign a confidentiality agreement, and will not close the contact with the outside world.

A few days later, the fat teacher didn't mention this matter again in class, and Zhang Yi didn't bother to ask, and gradually, this matter was left behind by him and forgotten about it.

In math class, the only thing that has changed is that the fat teacher seems to have found cheap labor, and from time to time, he calls Zhang Yi out and pulls him to the podium, and asks him to tell the students the ideas and processes of solving some exercises.

In these explanations, Zhang Yi's thinking has also been greatly exercised, and the knowledge of advanced mathematics has been more refined.

He also enjoys the more and more admiring eyes of his classmates, no one doesn't like compliments, and that kind of heartfelt respect is even more refreshing.

The optical disc production line has basically abandoned pirated software discs, and the production capacity of the production lines in Guangdong and Haijin is all used to produce micro-hardware and software compilations, but the supply is still in short supply.

Some software disc manufacturers are jealous of this huge profit and want to seek cooperation, but Zhang Yi refuses them all one by one, this kind of high-threshold software cracking work is not at all to participate in it.

And the monopoly profits brought by the high threshold are really attractive.

Seeing that cooperation is hopeless, and under the stimulation of high profits, he directly finds a bull who solves it with a high salary to try to crack the micro-hardware and software compilation.

The so-called cracking cattle have discovered that the shell of software encryption uses a never-before-seen encryption method, which cannot be cracked by all the methods that are known so far. The masters worked hard, but they returned one by one.

What's even more disgusting is that once the cracking fails, the disc will be completely scrapped.

If you want to crack it again, you have to buy a brand new micro-hard disc.

The completely scrapped CDs have made many cracking cattle really depressed about the undisciplined and bottomless way of making money by the CD author. The disc manufacturers who paid to crack it even looked at the discs all over the floor and wanted to cry without tears.

Although the price is not too expensive, it can't stand the large amount!

After Zhang Yi got the news from several disc manufacturers he knew in Guangdong, he was secretly vigilant while snickering.

No encryption method is one-size-fits-all, and spears and shields are always one or the other. It seems that in the future, it is not only necessary to use more complex encryption methods, but more importantly, to increase the number and variety of its own software.
