Tech Hammer

Of course, the academic cat cannot be a real cat, but a snack specially made by the Good Time Cafe. It is actually a waffle with various nuts, meat floss, and peanut butter on it. It is a good snack. According to the description in the cafe, this thing is particularly suitable for feeding cats, so it is named Yanbei Academic Cat. It costs 36 yuan per serving for external visitors. For teachers and students of Yanbei University, it only costs 32 yuan.

As for the indulgence after writing PAPER that Kong Wenjue pointed out, it is actually quite particular. The main subject is actually waffles, but it is not paired with those miscellaneous things. The sauce that is paired with it is honey, which means that the waffles are covered with honey, just like The sweet and joyful feeling after PAPER is finished.

From a psychological point of view, such a combination can produce certain psychological implications. Although they are not the same things, they can show the same preferences. From the perspective of saving money, it makes sense.

If he finishes eating one portion of the academic cat and is still unsatisfied, Kong Wenjue can push his waffle over without having to order another one. This is good, at least he can save money on ordering another snack.

Of course, this was just what Chen Diancheng had in mind. After all, he came with a purpose. From the moment they met, this top student from Ning Ban, the famous president of Ning Club, began to make various psychological profiles of the opponent in front of him. Trying to find out what kind of person this is.

After all, Chen Diancheng has never seen a living spy.

"Thank you, Senior Brother Kong. In this way, without wasting Senior Brother Kong's time, let's get to the point. I just learned that I went on exchange for a year last year, so maybe there are some things in Ningshe that I am not clear about. That's it, Because Ning Club has developed well in recent years, the number of club members has also increased, especially at Yanbei University, everyone is very enthusiastic to sign up for competitions and scientific research."

"And you know, our previous projects have been very successful. Although we are not doing it for money, these products have really made money, so we still need to give you some rewards. In terms of amount, it is not small. , you also participated in the random algorithm event project before. Although you are not a core developer, you should have received a reward of more than 100,000, right?"

Kong Wenjue nodded slightly and said, "Well, a total of 160,000 yuan, a subsidy of 20,000 yuan and a bonus of 100,000 yuan. I was quite surprised to receive this money abroad."

Chen Diancheng smiled and continued: "Yes, although the reward of more than 100,000 yuan is not a lot, many students are still very interested in being able to do what they like and receiving cash rewards. The current situation is that Ning Everyone is becoming more and more enthusiastic about participating in the club's projects. It was the same situation that I didn't see your application letter for the first time before. There were too many applications received in the background, and it was easy for them to slip through. Can you Do you understand?"

Kong Wenjue nodded and said confidently: "Of course I can understand this, but President Chen, Ningshe still has more undergraduate members. To be honest, although Ningban is very strong, most undergraduates have not really been exposed to scientific research. field, experience in all aspects is still too little, especially in terms of linkage and running-in, it is still far behind that of a graduate student. To tell you the truth, I have seen a lot of the world this time when I went abroad, and I have gained a deeper understanding of many technical issues. I know a lot about it, especially the glass slipper project, which actually requires very high requirements for wireless communication, which happens to be my professional strength, so President Chen must consider it.”

Chen Diancheng smiled even brighter and replied: "That's for sure. If I didn't have a special regard for you, Senior Brother Kong, I wouldn't have specially invited you here to talk, right? Undergraduate students are definitely not as capable as graduate students in all aspects. But other people I don’t necessarily think so, as you know, most of the club’s vice presidents, project leaders, etc. are also undergraduates.”

"So, now the club is preparing to launch a selection plan, which will be implemented soon. If you want to enter a popular project like glass slippers, you must first be assessed. All members who have submitted applications will have the opportunity to be assessed. And we, Ning, will guide this assessment Everyone will pay attention to it, it’s a very good opportunity, how about it? Is Senior Brother Kong interested?”

After hearing this, Kong Wenjue showed great interest and subconsciously asked: "Will Director Ning participate in Ningshe's assessment?"

Chen Diancheng immediately said: "That's for sure. You are also an old man who has participated in the project. You should also know that our project can be successful. Director Ning has helped a lot and often gives some guidance."

"Ahem... um, um, that's right!" Kong Wenjue responded awkwardly.

In fact, he really didn’t know this. Although he had indeed joined a key project before, he was purely doing some peripheral things in that project and was not part of the core team. Naturally, he didn’t know what the core team had to do when advancing algorithms and code. Without Ning Wei's guidance, naturally he could only listen to Chen Diancheng's deception.

"So, this is the situation now. If Senior Brother Kong is willing to participate in the assessment, I will send you the questions later. The questions in this assessment seem to be about mathematical modeling tools. Director Ning seems to mean to do A time series forecasting tool, probably something like the Prophet model, the specific requirements are probably that it must comply with the design specifications of similar products and have certain innovations. For more specific details, I have to go back and ask Director Ning carefully to find out, how about it?"

Kong Wenjue was stunned by these words.

This is really a bit - outrageous!

Does Ning Wei have a correct understanding of the brats like Ning She? Let these people do the Prophet model for assessment?

This technology is nothing new. It is nothing more than a process of predicting time series data based on additional models. Excellent Prophet can be used in many applications to generate reliable planning and goal-setting forecasts, and can obtain reasonable forecasts on messy data without manual labor. But it is very difficult to design this thing. Let a group of undergraduates do such a thing?

"President Chen? Academician Ning Wei assigns you undergraduates this kind of task?" Kong Wenjue asked subconsciously.

Chen Diancheng smiled and said: "Haha, is it difficult? Well, it is indeed a bit difficult! In fact, this kind of design is difficult, but you also have to have confidence in our Ning class. What kind of person is our Director Ning? Don’t you know? How strict are the requirements for Ning Ban? Besides, what we think is difficult does Director Ning also find it difficult? Taking a step back, this is not an exam, and it’s not like we can’t find foreign aid? For Ning She , if we can have foreign aid to do this well, it will also be a reflection of our strength."

Kong Wenjue nodded subconsciously and said, "That's right. That's okay. President Chen, give me the topic later and I'll try to see if I can do it."

Chen Diancheng smiled and nodded slightly, then lowered his voice and said: "Then it's settled, Senior Brother Kong, as long as you make it and it's almost functional, and let me gain face in front of Director Ning, I will directly recommend you to our company later. Glass Slipper Project Team. I will discuss it with you this time and I will definitely win you a core position. However, Ningshe will be re-elected in the second half of the year. We are all graduate students now. When the time comes, Brother Kong, as a key member of the project, you will have to vote for me. One ticket."

After hearing this, Kong Wenjue blinked and asked in a low voice: "What? President Chen, is there anyone in Ningshe who dares to take your position? Impossible, right?"

Chen Diancheng suppressed his smile and said angrily: "It was really impossible in the first place? But when our director Ning was having dinner that day, he accidentally said that I am now a graduate student and should devote more energy to research. Ningshe management can be let go if possible... Some people have heard this, and don't they have some ideas? We, Director Ning, are good at everything, but we are too lenient! Hey..."

Kong Wenjue nodded quickly and said: "Yes, yes, don't worry, President Chen, I have joined the project team, and I will definitely support you in this matter!"

"Okay, let's do this for today. If your project is done well and caught the eye of our Director Ning, a Ningshe project will be considered a P! If you are engaged in wireless communications, our senior brothers will also be engaged in the next generation of frame-based three-dimensional Monitors seem to need talents in this area. If you can join that project team, you will be outstanding! It is a national-level scientific research project with new chips and operating systems! If you can get in, you will not be involved in the Ten Thousand Year Plan. It’s even easier! You can basically choose any title you want, including Outstanding Young Scholars, Yangtze River Scholars, and Young Scientists!”

Chen Diancheng said, patting his chest.

After the business was finished, the two of them casually exchanged some other pleasantries.

Although he kept chatting, he did not forget to eat some snacks in front of him from time to time and take a sip of coffee. Although Wen Jue, who was opposite him, didn't say much, the snacks in front of him remained untouched...

Carefully spread the peanut butter evenly on the last waffle, put it into his mouth with satisfaction, and drank the last sip of coffee. Chen Diancheng clapped his hands and said, "Okay, I'll get here today and study it later." There is a lecture at the center that I have to attend, so I’ll leave first.”

"Um, President Chen, how about we add a WeChat account first, and then you can send me the question later? Otherwise, it would be troublesome to find people in Ningshe's group."

"Oops, I almost forgot, okay, should I sweep you or you sweep me?"

"I'll scan you."

"OK!"

After adding friends, Chen Diancheng walked away with satisfaction. How should I put it, after sitting down for an hour, he felt that Senior Brother Kong was really funny, but he just didn't know how to turn around and give this Kong the task assigned to him by Director Ning. Senior brother, how can you complete it...

…

Yanbei University, True 3D Display and Imaging Smart Optics Laboratory.

This laboratory was funded and established by Ning Wei about 20 months ago. Ning Wei set a small goal, Huawei and Huaxin Precision jointly funded about two small goals, and Yanbei University provided the space to build the laboratory.

According to the agreement signed by multiple parties, after the laboratory is completed, it will be managed by the Laboratory and Equipment Management Department of Yanbei University. The only thing is that the graduate students and doctoral students led by Ning Wei have free and priority access to all the equipment and instruments in the laboratory. The right to use and other consumables in the experiment are borne by the students themselves. They can purchase them by themselves, or they can apply to the management department for unified purchase.

At the same time, the laboratory has also formed partnerships with multiple laboratories in the school. Specifically, when the laboratory encounters some problems, the laboratory can come forward to jointly conduct research with professors from other disciplines, such as new materials laboratories, various physics laboratories, etc.

Of course, the funding source is mainly drawn from the project team of the Display and Imaging Optics Laboratory.

In fact, Ning Wei introduced strategic partners to invest in the construction of this laboratory not only to select research topics for his own students, but also to consider the adaptation of new systems and new chips.

To be more specific, in order for independent chips and systems to have a common market path and expand the market, they are trying to take a differentiated competition route. This is also the route Ningwei formulated after deciding to make its own desktop-level CPU products.

As for whether it would be successful, I didn’t think too much about it. Anyway, in Ning Wei's opinion, the investment is not much. If others don't invest, it's not a big deal for him to personally donate a laboratory to the school.

And according to various industrial reference data collected so far in March, the possibility of making it is still very high. The major materials laboratories in China actually have a lot of materials with outstanding properties in reserve. The only problem is probably that the preparation of some materials is not that easy, and there are not many ways to reduce costs for reference.

But these are not problems.

The cost of many materials remains high. In fact, the main reason is that there are not many applications that can be used in large quantities. This also gives production units no incentive to explore how to reduce costs. Or the advantages of the material itself are as obvious as the disadvantages, and there are not many application scenarios.

If we can make something first and open up enough markets, capital will naturally start to pay attention to the entire industry chain, giving them enough confidence and motivation to find ways to reduce costs and release production capacity.

Of course, this is the purpose of scientific research. Every advancement in application also represents the rise of a certain industry. The premise is that it needs to attract enough capital attention.

At this time, Zhang Dingxi from the China National Defense University was leading the project team's juniors to conduct a data inspection of the finished product in the laboratory.

This is a new type of display technology.

To put it bluntly, it took nearly a year and a half, a core team of 18 people, and more than a dozen foreign aid experimental project teams, and the final designed engineering sample actually looked ugly.

How should I put it? It is a square frame made of several vertical strips of unknown white material. The shape is somewhat like an old-fashioned CRT monitor. It is a non-standard hexahedron with a large front and a small back. It is mounted on a bracket. But it is larger than those big monitors of the past. The screen on the front is 32 inches. But unlike those old CRT monitors, its screen position and the upper surface are both hollow, and your hands can easily move from these two positions. Into it.

The remaining surface is closed with a translucent material. This translucent material is tightly clamped in the middle of the frame. The workmanship is not particularly detailed, and some metal circuits can be seen in the gaps.

However, this is also the reason why final packaging is not performed for the convenience of operation. You only need to make a few matching insulating seals at the cracks, which can not only isolate dust, but also make it more beautiful.

Zhang Dingxi, wearing a white coat, stood in front of the screen, nodded to the two assistants beside him, and said, "Turn on the power and see how things go this time."

The young assistant standing next to the test bench nodded and pressed the switch on the side of the test bench. The connecting rods around the frame lit up one after another. After they were all lit up, the twelve connecting rods all lit up red simultaneously. , green, and blue, and then the blue light and shadow gradually turned purple, until finally it completely dimmed, returning to the appearance when it was not powered on, leaving only the power indicator light directly in front of it still shining with a weak white light.

"The first overall test of the three-dimensional display frame has begun." Zhang Dingxi paused after speaking, and then said again: "Change the lamp."

The lights in the laboratory dimmed instantly, leaving only a faint yellow light.

Zhang Dingxi then picked up the connecting cable from the side frame of the monitor and inserted the HDMI interface from the cable into a square black box next to it that was connected to the console on the other side.

"Image test No. 1." Zhang Dingxi nodded and ordered, then looked at the monitor nervously.

The assistant beside him had already begun to operate on the operating table. Soon the signal began to be injected, and there was obvious light and shadow gathering in the box. About three seconds later, a three-dimensional creature lying in the box looked like March. The three-dimensional kitten image gradually appeared in the box.

However, Zhang Dingxi's expression changed from clear at first, to serious, and finally his brows wrinkled.

Although the general outline after molding can be recognized as March, the clarity is obviously not enough. I can see the cat face clearly, but just like a short-sighted person looking at distant objects, it looks a bit blurry, especially the yellow and white ones. It is also difficult to distinguish the position of the fur edge and the whiskers on the face that represent the cat.

"The clarity is not enough, adjust the parameters..."

"Brother Zhang, the system shows that this recommendation is already the best result."

"Okay, record all the data. Start the No. 2 touch test."

Soon, the second test will start.

The image of the kitten gradually disappeared, and this time a cube gradually appeared on the screen. Facing Zhang Dingxi, there were nine small squares with four colors arranged in a chaotic order. There is no doubt that what was formed this time was probably a Rubik's cube.

Zhang Dingxi took off his gloves, raised his right hand and reached into the box. He placed his hand under the Rubik's Cube. He held it up and twisted in the void, but the Rubik's Cube did not move. Zhang Dingxi frowned again and raised his hand two inches. From the visual perspective The effect seems to be that it has been cut into the lower part of the Rubik's Cube. This time it is twisting, and the Rubik's Cube finally follows the direction of Zhang Dingxi's hand twisting and moves simultaneously.

Although it looks a little weird because the hand is inserted into the lower layer of the Rubik's Cube, the movement speed of the Rubik's Cube body is synchronized with the movement of the hand.

The assistant on the side stared at the console screen and read out the suggestions given by the system: "The accuracy of the automatic control position judgment is not accurate. It is a hardware problem or an algorithm problem to be determined. You can try to add two cameras at the lower B23 point and C46 point. , the sensing data is stable, and the synchronization adjustment is 99.632%."
