Tech Hammer

Really, when Apple confidently placed that picture in the most conspicuous place on its official website, it was destined that the Spring Festival in China would not be peaceful! Linkage spanning tens of thousands of kilometers has always been so novel and interesting, and when the Internet becomes a field of public opinion competing for points, even various hot searches will become extremely interesting.

Everyone is concerned about Apple supplying its own CPUs to Huawei. They are also more concerned about the pros and cons of the next generation of Huawei mobile phones and Apple products. At this time, they are also concerned about whether the Apple car can directly dominate the electric vehicle market. Tesla.

It's outrageous. If calculated according to the Chinese lunar year, this is the second time in the same year that Tesla has been passively included in the hot search by netizens. For the first time, because the founder made some lofty words about landing on Mars within five years and immigrating millions of people to Mars within thirty years, a cat on the Internet used hundreds of Weibo posts to criticize Tesla and it became a hot search topic. .

This time Apple posted a picture, and everyone began to collectively discuss the superiority of Apple and Tesla's car-making capabilities. Originally, this issue did not need to be discussed. After all, Apple had only made mobile phones before, and even concept cars had not been shown to everyone yet. Tesla has sold more than one million smart electric vehicles around the world, but it really can’t stand up to that picture released by Apple. It’s so cruel!

Tesla is indeed very powerful in the field of electric vehicles. All three types of electricity are being blown to the sky. So the question is, can the battery system composed of 18650 cells that Tesla is proud of can run 1.99 kilometers? Can L4 autonomous driving be achieved?

Originally, countless netizens on the Internet were still very rationally discussing whether Apple could really achieve the awesomeness boasted in the pictures. However, the Internet is always very easy to be provoked by a small group of people. When there is a group of people who don’t know what it is. After Tesla fans began to ridicule Apple's PPT car-making, it directly angered countless serious Apple fans.

So the war that will never be lacking on the Internet began. Fans of the two major technology companies began to attack each other in various ways. Fans of Tesla can cling to the point of building a car through PPT, while Apple fans will draw the last sentence on the picture as a key point to popularize science everywhere, and don’t forget to take advantage of the fact that Tesla has been promoting autonomous driving for many years. I can only say that my company is an assisted driver...

Later, the leaders of the two major companies were compared, and a small number of Apple fans began to use those Weibo posts posted in March to ridicule Lao Ma for boasting that he could not only immigrate to Mars, but also circle the solar system three times. He also provided detailed evidence to prove how rigorous and successful Tim Cook is as a CEO. For example, this CEO is the most amazing supply chain management guru on the planet. His precise control of the market exceeds everyone’s imagination. Therefore, Apple can never take aim without aim.

Special fans can cite examples of a group of big players who entered new energy vehicles and finally surrendered. For example, the once-famous man who was suffocated by his dreams had already built the most advanced electric car on the earth through PPT. But countless years have passed, and not only has the boss never returned, but the electric car on the PPT has not been seen. Really appear in the public eye. As for Lao Ma, although he sometimes speaks a little willfully, his rocket company has already sent Tesla into space.

The most depressing people during this period are probably those netizens who are both fruit fans and special fans. It is so disturbing to see the two groups of people quarreling on various Internet platforms. It just so happens that the fighting power of the bosses on both sides is extremely amazing. When they are in trouble, the so-called rightful guests can be directly labeled with various labels that make people feel unhappy. But all this happens during the Chinese New Year, which should be a happy time. node...

Yes, just when the entire Internet is buzzing with Apple's strong official announcement, Chinese people are also ushering in the most festive day of the year - the Spring Festival!

This Spring Festival is also very special for the Ning family. This is the first time the family has celebrated the festival outside of Yancheng, especially since it is not only a family of three but also a daughter-in-law. Lao Ning and Ning's mother also hung the Spring Festival couplets at the door early, and the refrigerator at home was filled with various ingredients.

Ronny Letun and Princess Isabel climbed the mountain together and left the capital with Yan Ming the next day and went directly to Shenzhen. After visiting Huawei, they set off directly from Shenzhen Airport to return home. Ning Wei also officially started enjoying his New Year's holiday the day after climbing the mountain.

Ning Wei was aware of the quarrels on the Internet, and he seldom went online even during breaks. But with March, the public opinion assistant, it was impossible to miss such a large amount of discussion, but Ning Wei did not choose to speak out, although countless people @him on Weibo, privately messaged him, and even media outlets above the provincial level approached him in a roundabout way, hoping that Ning Wei could express his opinions, but Ning Wei firmly refused.

The reason is simple. It is almost impossible to have a rational discussion on the Internet. No matter what he says, he will definitely not be able to satisfy the fans on both sides. Who would be interested in speaking out for such nonsense during the Chinese New Year, and then being scolded on the Internet for no reason?

Let’s do a science popularization in March. It may take hundreds of pages of papers to tell both sides of the debate how to view these scientific issues. For example, the relationship between battery capacity and energy density, the function of the catalyst, how the battery anode structure affects the battery energy density, what are the core points of L4 autonomous driving, and what information does the machine brain use to determine what measures to take when encountering complex road conditions? What mathematical theories are involved...

In fact, it doesn’t take much effort to get it out. The key is that no one will understand it or even misinterpret it in various ways.

The most important thing is that Ning Wei is happy to see the outcome of this kind of argument. Let the two sides argue loudly. It is better to fight with a louder voice and give him time to silently make something, and then successfully surprise everyone. This is quite good. good. He had promised Liu Wei that he was going to do something big, so naturally he should stay dormant until the big thing was done.

Ning Wei really wants to comment on the deal between Huawei and Apple. After all, it is rare for such direct competitors to reach an agreement. Both parties feel that they have made a profit and achieved a so-called win-win situation. This is very rare! Ning Wei feels that he can directly blow up this cooperative attitude! It's a pity that although there are a lot of disturbing news from the outside world, the two large companies have always maintained silence and did not respond to these news at all, so they had no choice but to give up.

In short, having a happy New Year is the way to go!

…

During the New Year's Eve dinner, Liu Wei, who was still working overtime, was dragged home by Ning Wei and had a fairly lively New Year's Eve dinner with a family of five. Yes, even March has a place. Ning Wei called up March on his mobile phone and fixed it on the table with a bracket, allowing this kitten living on the Internet to participate in this feast. Liu Wei and Ning Wei also made an exception and drank two taels of white wine with Lao Ning.

The meal lasted from five to seven, until Ning sent a video to her sister-in-law who had returned to her hometown, which made it even more lively. Ning Wei also met his future mother-in-law in the video. You can feel that the mother-in-law on the opposite side has carefully packed herself when posting the video. Her clothes are not luxurious, and her face is also full of traces of time. But there are still some similarities between her eyebrows and Chen Shuang's.

The atmosphere probably reached its climax at this time. After Ning Wei took the phone after drinking two taels, he said directly without thinking: "Mom..."

In exchange, there was a look of astonishment on the face of classmate Jiang's mother across from him, a flush on both sides of classmate Jiang's face, a wide-mouthed smile from Ning's father, and an angry but understanding eye roll from Ning's mother. Then Ning ignored classmate Jiang who was tugging at his clothes from below, and first turned his face to Jiang Chenshuang and said confidently: "It's not wrong. Mom will cry like this sooner or later. Sooner or later she will cry like this."

Then he faced the phone camera and emphasized: "Don't worry, Mom, I will definitely help you take care of Chenshuang!"

Then the mobile phone was passed to Ning's father. After saying hello to his future in-laws, Ning's mother took the phone and the two mothers started chatting.

The dinner was almost over here. Ning's mother, who was already enthusiastic, held her cell phone and started chatting with her future parents-in-law. Old Ning took Liu Wei and started bragging about his glorious experiences when he was young. Student Jiang blushed and started to clean up the leftovers on the table with Ning Wei who had to help. The kitten was left alone on the dining table in a daze. Maybe as a robot cat, he was not very capable. Understand why this is summoned on this day.

The day of universal celebration passed like this. The Ning family did not have the habit of keeping up the New Year's Eve. When they were tired at night, everyone went back to their rooms to rest. On this day, Ning Wei watched helplessly as his mother walked into the room with classmate Jiang. That's all. When closing the door, my mother gave Ning Wei a meaningful smile.

Of course, for Ning's father and Ning's mother, they thought this year would be the most leisurely Spring Festival. Ning Wei also said that he only needed to take Chen Shuang to visit the tutor, so Ning's mother also began to discuss with Ning's father whether to wait. After the two little guys took their wedding photos, they took advantage of the Spring Festival holiday to take their children and fly directly to their daughter-in-law's hometown with classmate Jiang to reassure the in-laws and settle the affairs of the two children.

However, on the first day of junior high school, they discovered that they had underestimated their children's dignity, and they had a new understanding of Ning Wei's current status. In the past, they only knew that their son had great potential, but to what extent they had no idea. However, these years have given them a more accurate understanding.

Ning Wei's mobile phone is extremely busy, and there is an endless stream of visitors at home. Moreover, in the eyes of the two old men, these visitors were all important figures, including lecturers, professors, executives of a certain company, bank presidents, and even an academician named Tan who visited hand in hand with the school leaders and sat down and took his son. What a great chat.

Not only were these people well-dressed, they were extremely powerful, they had gentle faces, and they also spoke very nicely. This completely put Ning's mother off the idea of ​​a Spring Festival holiday, and she also understood why Ning Wei changed his story in yesterday's video. This was to reassure the Jiang family.

Neither Ning's mother nor Ning's father had a high level of education. They only knew that Ning Wei's achievements were great, but they didn't have much idea of ​​how great they were. Ning Wei rarely talks about what he is doing in front of them. The only thing they probably know is that their son won a grand prize, made a lot of money, and will be on the rich list in the future. But now it seems that, regardless of money, what his son is doing is the most important, and it can make many big shots bow.

This also makes Ning's mother very happy. Although many times some of the things Ning Wei does make her feel a bit bastard, at some critical moments her son is still very delicate and gentle, which is good. As a mother, I really don’t ask Ningwei to be able to make a living every second, but I want Ningwei to be safe and stable. From observation these days, Xiaojiang is really a very delicate and caring girl. She felt at ease leaving it to Jiang.

…

Jiangcheng University, Software Laboratory. This year's Chinese New Year, most members of the entire EDA project team will not be able to take the holidays. Of course, everyone’s resentment is not that great, because they are paid to work overtime during the New Year, and the overtime pay is really high. Calculated, if you clock in all the seven days of vacation, you can get about 23,000 yuan, which is enough to mobilize everyone's enthusiasm.

Yes, after Ning Wei got out of the EDA project last year, it does not mean that the project was abandoned. On the contrary, after a year of development, the minimalist EDA project has been developing well. With the spring breeze of turbulence algorithm being accepted by the world, this The usage rate of basic design software is also increasing.

Of course, this is also due to the fact that both parties attach great importance to this project. In particular, Huawei's chip design department will continue to put forward requirements for the software group based on its specific needs, and then both parties will continue to promote the research and development of this EDA software around these needs. By solving those practical needs, it has indeed given the technical staff of the entire department a sense of honor.

China's first EDA software that can comprehensively solve chip design problems may be completed in their hands. Colleagues who make similar software have even begun to visit and study in the laboratory. Professor Han, the current leader of the EDA software project team, has also begun to be invited. Go to various places to give reports. This professor with an upright personality always mentions in almost every report the story that when he was brought into the project team, he was not optimistic about the project, but was slapped in the face...

The effect is also very obvious. Almost all EDA software people in China probably know that Dr. Ning, who is now famous, proposed that China build its own EDA software when he was an undergraduate, and he put it into practice, even though some people strongly opposed it at the time. But the undergraduate student back then successfully completed the project.

However, the old professor who strongly opposed this project became the person in charge of the minimalist EDA project after Ning Wei went to Yanbei University to study for a PhD. A legendary historical story may appear in textbooks a hundred years from now, and its educational significance can be interpreted in various ways according to the author's mind...

Of course, there is nothing much to say about these. Ning Wei and Lao Han actually have very strong characters in everyone's opinion. Moreover, Lao Han did this very openly. Although the world was bragging about Ning Wei, Professor Han had never contacted Ning Wei in private. Although the two had added WeChat and exchanged communication numbers, Even during the holidays, Professor Han did not send a message to Ning Wei.

But these two days he really couldn't bear it anymore.

Because just these days during the Chinese New Year, a pre-release version was set up in the version management server of the minimalist EDA software through a new high-privilege account, and this pre-release version was undergoing version changes with extremely exaggerated efficiency. Twice a day, version changes were carried out without hesitation, and the weapon library continued to expand at a speed visible to the naked eye.

As the person in charge of the EDA project, Lao Han naturally has the greatest management authority, but he only has the authority to read this pre-release version of the software. Forget it, what surprised him even more was that after running this version of minimalist EDA, even he couldn't understand the arrangement of components and groups in the component library...

When this happened, Lao Han immediately contacted Huawei's business contact person, but learned that this pre-release version was not uploaded by Huawei. Then there’s no need to ask. Although Ning Wei quit the minimalist EDA project team a year ago, he still has an administrator account and can create a new account in the version server. But where do we want to play?

Unable to bear his curiosity, Lao Han finally decided to call Ning Wei and find out.

The call went through quickly, but no one answered. Called again, still no one answered. I sent a video via WeChat again, but still no one answered. With nothing to do, Lao Han simply sent a message on WeChat.

By noon, I finally got a call.

"Professor Han, I'm sorry. I was taking wedding photos just now and I didn't bring my phone with me. I just saw your question."

Taking wedding photos on the third day of the Lunar New Year...

After hearing this, Han Wenqing felt a little dizzy. This young man really doesn't like to play by the rules! After sighing with emotion, I felt a little envious. After all, Ningwei had just graduated from undergraduate degree for one year, and he was already planning to get married?

Although the two of them did not contact each other often, Lao Han often paid attention to some things about Ning Wei. He also knew that Ning Wei found a girlfriend after going to Yanbei University. It's really not Han Wenqing's gossip. The main reason is that it was a big deal at the time. First, there was a scandal with a princess of a country. It is said that the whole of Europe was shocked by the scandal. Then Ning Wei officially announced on Weibo that he was in Yan. Peking University has a girlfriend.

At that time, countless people were turned into detectives, hoping to find the lucky girl. Later, photos of the two dating together were exposed, and Lao Han also saw the appearance of classmate Jiang on the Internet. Judging from the photos, she is indeed a very pleasant girl, young and delicate. In addition, she was admitted to Yanbei University for her undergraduate degree, which means that she must have a very high IQ, and the two of them are considered a good match. Unexpectedly, it seems that not long after that, the wedding photos have already been taken?

"Oh, Xiao Ning, congratulations! You must let me know when the banquet will be held." Professor Han said sincerely.

"Haha, Professor Han, that is necessary, and it will definitely not help you save money! By the way, I read your question. The pre-release version of the EDA software is for circuit design using new technologies and new materials. For the time being, It’s not used yet. You don’t have to worry about it. The components and groups in the component library are also the most ideal three-dimensional channel design, and they will definitely need to be continuously modified according to the specific products in the future.”

"New technology? New materials?" Han Wenqing was a little confused.

"Yes, with the innovation of chip materials, the previous design software will naturally not keep up with the times, so the tools must be prepared in advance. This pre-release version is specially developed for the design of new material semiconductors." Ning Wei replied matter-of-factly .

Han Wenqing knew that Ning Wei liked to do big things. For example, when he came up with the turbulence algorithm, he launched this EDA project. But how long ago did Ning Wei want to fundamentally subvert the development direction of electrical engineering?

People who don’t do this may not know how difficult it is. But Han Wenqing happened to be studying this industry, so he naturally knew what it would mean if new materials were to replace the current silicon semiconductors. In fact, countless laboratories around the world are trying to use new materials to replace silicon as a new generation of semiconductor materials. However, considering the earth's resource content and the difficulty of preparing semiconductor materials, silicon is still the dominant semiconductor in the world.

Silicon is everywhere and cheap. A complete upstream and downstream industrial chain has been formed for silicon-based semiconductor technology around the world, and everyone is accustomed to designing various semiconductor products on this basis.

If better new materials can be designed to replace silicon on a large scale and become the first choice for the next generation of semiconductor materials, it will first represent an overall reshuffle of the entire semiconductor industry. Nowadays, the giant companies that are showing off their power are very likely to turn from prosperity to decline. The various patent barriers that those giant companies applied for in detail in the past have all become waste paper.

The most important thing is that those chip structures designed for silicon-based chips will also be swept into the garbage heap of history. This affects more than just semiconductor giants such as Intel, AMD, Qualcomm, etc. It also includes the entire track chip upstream and downstream industries.

For example, ASML is the dominant giant in the field of lithography machines; AMAT, LAM, TES, and Huaxia International, which produce etching machines; those giant chip foundries TSMC and Samsung Semiconductor; and even the three major EDA software companies in the chip design field The kings are Synopsys, Cadence and Mentor Graphics; followed probably by chip design companies and chip packaging factories all over the world...

After all, materials have changed, and packaging technology has also changed. The applications of the entire semiconductor field are not only mobile phones, computers, tablets, but also automobiles, smart homes, robots, aircraft, satellites, spacecraft, and all types of devices that need to use semiconductors in the future. equipment.

In the past, when industry segmentation was not so exaggerated, the emergence of new materials would not have such a big impact. But in this era when humans can no longer leave the Internet or semiconductor equipment, if there are new materials that can replace silicon, it will really suffocate countless people!

At least at this moment, Han Wenqing felt like he was starting to suffocate for his dream!

If this can happen, minimalist EDA software, as the first software that can use new materials to design semiconductor chips, may become an essential chip design software popular around the world. As the person in charge of the project in the post-minimalist EDA era, although he actually did not do much in this work, his name must be mentioned when history books describe this period.

"Mr. Xiao Ning, are you serious?"

"What's wrong with this? Just give it a try. When we were building our own EDA software, I actually said the same thing. No matter whether it can work or not, you have to try it first. If it works, it will work. If it doesn't work, it will work. I have accumulated experience! But let’s just say one thing, I think the possibility of this happening is very high, so Professor Han, you have to work hard! Hey, I won’t say anymore, I will eat a few bites of rice quickly, and I will take five more photos in the afternoon. Get dressed! Let me tell you, taking wedding photos is such a laborious job! Goodbye, Professor Han!"

"See you!"

After saying that, the person on the other end quickly hung up the phone, leaving Han Wenqing holding his phone and looking at the pre-release version in the server in a daze!

Really compared to the software in front of me, the battle between fruit fans and special fans on the Internet is simply weak...
