Chinese entertainment for engineering students

The popularity came much faster than expected, which made the publicity personnel of New Line really surprised and worried. Surprisingly, the effect was achieved without spending much money.

What I'm worried about is, if the film doesn't keep up with the schedule and delays, what kind of trouble will it cause, and what kind of infamy will it get if the actual results of the film are not satisfactory.

Wang Xu, on the other hand, remained unmoved and continued to carry out his logistical work step by step. He sang a few songs in the evening and then went home to write report materials and slides for speeches.

The film "The Matrix" can be said to be a complex of firsts on the Internet, the first online open source background world, the first science fiction novel serialized online, the first script to be revised online based on feedback, and the first The filming progress of this movie will be broadcast live online.

And what era is it now, the early stage of the Internet era? If nothing else, just so many firsts are enough to make the news hot.

This brand-new thing, a brand-new system, is nothing new unless it is a hot search topic. Oh, by the way, this thing isn’t trending at the moment.

Wang Xu once thought about what it would be like to use current equipment and software to implement a product similar to Weibo. The final conclusion was that it would die.

Are you surprised? We can all make movies in 3D, so why can’t we make a Weibo? The answer is that it can be done, but the investment in software and hardware equipment required will kill the company from the beginning.

If nothing else, let’s just talk about likes. It seems to be an inconspicuous little function on Weibo. It’s just a thumbs-up icon plus a number, and it’s gone.

But for such a small function, if it is used by several people, then a programmer may be able to create it for you in an hour.

But if you want to realize this function for millions of users, it will be a huge project. For example, there are four apples on the table. You tell me which ones you like, and then I can find them for you next time.

But if there are 1 million people and there are 100 million apples on the table, I will not be able to find that apple for you at all.

In order to solve this problem, the system must first record 100 million pieces of data to remember these apples, and number each apple.

Then, the system also needs to remember which number you like. There are 1 million people, and they all need to remember how many of the 100 million apples they like. Assuming that everyone only likes 100 apples, then I need 1 million People * 100 = 100 million pieces of data to record.

You see, there are already 200 million pieces of data before retrieval. The storage alone is already killing the machines of this era.

Even in 2020, this question can be used as a company interview question. How do you need to solve the storage and retrieval of these 200 million pieces of data.

This is why it was not until 2006 that Weibo was launched for the first time in Ugly Country. It also limited the length of each message. It was not allowed to send too long messages. The length was limited to 140 characters and only 70 Chinese characters.

The core of Weibo is actually a huge number of users. Now, even in ugly countries, the total number of Internet users is just over 10 million, accounting for less than 3% of the American people. The number of Internet users in the world is only more than 20 million. It's even more insignificant.

But even with this user scale, assuming only 10% of people use Weibo, the amount of data will be catastrophic, at least for the hardware of this era.

Therefore, most of the Internet at this time is text-based, and its functions are also very simple, focusing on display. Because GIT provides certain interactive capabilities, it is almost regarded as a free activity center by others, and it has to join various restrictions to avoid affecting the main functions.

Even for users outside the education network, there are many restrictions, just for fear of the influx of too many users, which will eventually lead to the collapse of the entire system.

Even so, each GIT mirror station now requires a dedicated computer room to store a huge server cluster.

Inspur, Tongfang and Founder all rely on this to make money. Their servers are now selling well because they are adapted to various network services on GIT, and are exported to many countries.

Therefore, what applications can be developed in which era is actually highly consistent with the development of science and technology itself. It's the early days of the Internet, so we can only play simple things.

Text is the main medium, and pictures are already the largest information carrier. The size and resolution must be limited, otherwise, your system will explode in minutes.

It is simply impossible to move the movies that Wang Xu is working on to the Internet. The bandwidth of the main website is not enough for him to transmit.

The movie is progressing well and is scheduled to be completed by the end of August. So far, it seems that there is not much of a problem. The progress of special effects is now accelerating, which is ideal. There were some stumbles at the beginning, but with the coordinated efforts of all parties, it passed smoothly.

In this kind of purely technical work, once the problems encountered at the beginning are solved, the proficiency will increase with repeated use, and the subsequent speed will only get faster and faster until it reaches a peak and stabilizes there.

The editing work is carried out almost simultaneously with the special effects work. During rough editing, a lot of the content is still on green screen. Later, when the special effects are ready, they can be replaced. This is the benefit of digital editing, and modifications will be much easier.

The hardware Wang Xu invested in for this film is real. The disk array with a capacity of dozens of terabytes is worth a lot of money. This is the price of a purely domestic product that only uses the software on GIT and uses ordinary hard disks. , if it were imported, this set of disk arrays alone would consume all Wang Xu's funds.

This is of course also because the film industry itself has different stability requirements from banks and other units, so it is possible to directly use the low-end version.

After all, from beginning to end, that is, half a year, even if it is a consumer version of the hard drive, it will generally not cause any problems after being used intensively for several months.

Rather than asking for information to be secure for several years like a bank, Wang Xu could only shake his head. Later Internet manufacturers rarely use high-reliability products.

Because even a six-nine (also called eight-nine) product with a reliability of 99.999999%, in a giant cluster that often starts with tens of millions of units, means that dozens of bad hard drives will appear every day and need to be replaced. .

You must know that for any product, increasing the reliability of the last 9 often means increasing the price hundreds or thousands of times. So using maintenance strategies to solve problems and using low-priced product alternatives is of course a reasonable and cheap thing. The choice was made.

At least so far, Wang Xu is very satisfied with the current product situation and has not had any problems.

Moreover, Great Wall's maintenance staff have been keeping track. This is also the first time they have sold such an integrated product.

They have recently changed leadership and have significantly increased investment in research and development, and the new disk array product is one of their attempts.

If successful, they will become a supplier to Inspur, Tongfang and Founder, providing low-cost storage products for their parallel machines, workstations and servers.

Moreover, the PCs they produce will also use similar technology to ensure greater capacity and provide higher-end product options.

Wang Xu set the plan for the end of August. The reason is very simple. Wang Xu will start school in September. In the first year, he basically just went to work and had nothing to do. He could make movies and mess around. But starting from September this year, his graduate studies It's time to report, and he has to go to school and be busy for a while.

He is the supervisor of doctoral students. He was specially approved this year. It is not an arrogance for an associate professor to lead a doctor. There is a precedent. Wang Xu can naturally do it. As for the full professor, it is estimated that next year it will be a certainty, and he will be one level a year. , to be fair, it can be said that he is so fast that he has no friends.

In the first class, he will recruit five students, two in artificial intelligence, two in condensed matter physics, and one in clinical Chinese medicine psychology.

Don’t forget, he also has a doctorate in the medical school, and they also gave him the title of visiting professor. If it weren’t for this certificate at that time, Whitney would not have let him see the doctor honestly. .

This is not a fake, he is a doctor who can treat patients seriously there. His name is on the Traditional Chinese Medicine Department of the Third Hospital and the Depression Department of the Sixth Hospital, but Wang Xu doesn't have much time and rarely goes there.

If you want to say which school knows the most about surrounding things, it must be the Medical College, because many hospitals in the Imperial Capital are not good at this time, and the designated hospitals for teachers from surrounding universities are all in the Third Hospital of the Imperial Capital Medical College.

Now if you ask any teacher nearby where to go for medical treatment, the answer will definitely be the Third Hospital. This Third Hospital refers to the Third Affiliated Hospital of Imperial Medical College, or the Third Hospital for short.

Therefore, there are really many teachers who come here to see doctors, and many are hospitalized. Therefore, it is possible for anyone to hide the major events in the university circle, but it is impossible to hide them from the medical school.

It would be fine if Wang Xu had always been just fanning the flames in the field of science and engineering, but this guy actually came to ask for cooperation. The project turned out to be a brand new topic, "Music-Assisted Traditional Chinese Medicine in the Treatment of Depression."

In this era, the field of depression is almost a blind spot in China. In the 1990s, there were many physical diseases that we still didn’t know how to treat. No one cared about mental illnesses.

Unless you are really schizophrenic, irritable, cognitively impaired or simply crazy, everyone will know it is mental illness.

Depression is not even considered a disease in the public mind. Most people think that it is a simple situation such as a bad mood or a low mood.

Things like "I'll be fine in a few days, I'll be fine if I have a good meal, I'll be fine if I go out for fun" are common responses to such illnesses.

Depression is actually a very old term. It is said that Socrates made various discussions. Socrates does not know whether it is true or not, but at least the word depression was used during the Renaissance and became popular among various artists. It once became a very fashionable and romantic disease.

Domestic traditional Chinese medicine actually had a very deep understanding earlier, and there is a so-called depression syndrome in the theory.

It refers to the main clinical manifestations caused by emotional discomfort and qi stagnation, such as depression, restlessness, tightness in the chest, swelling and pain in the chest and hypochondrium, irritability and crying, or foreign body obstruction in the throat. A type of disease syndrome.

You see, the description is more accurate and the treatment is more effective than the romantic disease.

Depression truly became a widely recognized disease. It was not until Swedish Professor Carlsson won the Nobel Prize for Medicine in 2000 that it was widely reported in the news. People began to gradually understand the "dopamine" secretion problem that may cause depression. disease.

Carlson studied "dopamine", a neuro-signaling substance. Now everyone thinks that abnormal secretion of "dopamine" may lead to various changes in people's emotions.

Moreover, this has been confirmed in scientific experiments, but it is undeniable that adjusting dopamine can only be effective for some patients with depression, and there are still many people for whom taking medication has almost no effect.

Therefore, the pathogenesis and treatment of depression are still under research and exploration even in the time period that Wang Xu experienced.

In the clinical diagnosis of our country's medical community, especially in the 1980s and 1990s, most patients who Wang Xu thought were depressed were considered to have another disease called "neurasthenia."

It was not until the 21st century that the term depression was gradually recognized by mainstream medical institutions in China, and it was also classified into symptoms like neurasthenia.

Basically, after a little mental exertion or light physical exertion, you will feel dizzy and very tired, but the duration is short and you can recover after a rest, which is generally considered to be mental weakness.

Relatively long-term, long-term physical depression, negativity, lack of fun, suicidal tendencies, etc. that lasts for more than two weeks and cannot be relieved by rest will be regarded as depression.

In fact, in later generations, mainstream hospitals rarely used the diagnostic term "neurasthenia". In foreign countries, some hospitals no longer even distinguish between the two, but instead recognize them as different stages of depression, with different degrees of severity.

Wang Xu brought various views and cognitions in this area to the domestic medical system in advance, and even made full use of the combination of traditional Chinese and Western medicine to successfully treat and alleviate some patients.

This allowed the medical school to see great prospects, and even began to study special Chinese patent medicines for depression based on Wang Xu's formula, and some progress has been made so far.

In particular, the introduction of music therapy has opened up a whole new way of treating mental illnesses, and may even be extended to other more complex psychiatric fields.

This is not a simple achievement. If it continues to be expanded, it may really be another Nobel Prize-level achievement.

You must know that many mental illnesses cannot communicate effectively. When humans lose language as a necessary means of communication, how should you understand the spiritual world of a mentally ill person, and how should you intervene?

Music may really be a bridge that allows people to communicate more directly with the untouchable spiritual realm.

Now Imperial Medical College's research in this area has not only focused on Wang Xu's topic, it is a clinical topic. Because it does not involve new drugs, traditional Chinese medicine plus listening to music can directly enter clinical practice in China.

Animal experiment? Don't be ridiculous, are you sure animals can have the same reaction to music as humans? Rat or monkey?

As for traditional Chinese medicine, it can be prescribed directly. Unless it is developed into a Chinese patent medicine, strictly speaking, animal experiments are required, which also require several rounds, but this does not affect the way of prescribing treatment at all.

The only question is, where does the music come from, how is it written, how is it sung, and what is the principle.

Wang Xu has not yet found the answer to this matter, at least for now. Of course, he has also made many attempts.

Wang Xu has provided several songs for depression music. In addition to "Under the Sea\

,"Wang Xu also guided Wang Fei to sing a very special version of "Daughter of Heaven", which was a more ethereal and higher-range version, almost reaching the limit of what Wang Fei can achieve now.

This is also an attempt by Wang Xu, that is, instead of doing it himself, let ordinary people perform the singing.

Because it introduces some hypnotic techniques that Wang Xu learned in other worlds, the score is particularly complex. It is an all-round cooperation of orchestration, vocals, and rhythm.

Even Wang Fei couldn't follow the singer's will at this time. Under the guidance of Wang Xu, Wang Fei put in a lot of effort to record it successfully.

Wang Xu sent this version to Zhang Guorong and Chen Baiqiang, and it was also used in Whitney's treatment process. The experimental results were gratifying, and this song was equally effective.

This seems to mean that those metaphysical contents may have other possibilities in this world. Yes, religion has always played the role of spiritual mentor in this world.

Buddhist chants, Christian chants, and ancient poets' chants all have a similar hypnotic effect. Such results made Wang Xu very happy and he also made some other attempts.

For example, he asked Luo Qi to try and changed a rock song for her to sing, but the result was that it obviously didn't work, so Wang Xu didn't understand the specific principle.

Similarly, when Whitney was being treated at his place, she also tricked Whitney into recording a special version of "I will always love you". After many attempts, he also changed from this song I feel that kind of spiritual stimulation in the song.

These three songs were sent to Imperial Medical College for various clinical trials, case collection, and standard medical research procedures.

They have discovered some things, for example, these songs have different therapeutic effects on different people, and mixing them is more effective than using them alone, etc. However, because there are too few cases and lack of data support, they have not yet been able to form a paper.

For example, decoction treatment can significantly enhance the therapeutic effect. For example, the introduction of acupuncture can also enhance the effect. Further signs such as staged therapy is more effective than continuous treatment have given these doctors a great deal of confidence and a bright future.

The treatment cases themselves can be published in the medical field, and they have recently published many papers in medical journals. It can be said that they have gained a lot.

Although the published paper has not attracted widespread attention from the medical community, some domestic and foreign medical institutions have already sent letters for consultation. Especially since the launch of the education network, the number of medical schools that have sent emails expressing concern has increased significantly.

All this shows that Wang Xu's therapy is attracting the attention of the world. Maybe it has not had such a big impact yet and is still just a small seedling.

But the sand becomes a tower and the armpits become fur. Maybe one day, the seedlings will grow into towering trees.

Imperial Medical College was separated from Imperial University back then, and was later taken back by Imperial University. Then by then, will Wang Xu be a double professor at Imperial University?

Or should I remind Mizuki to cut off Di Da’s Hu? As a Shui Mu person, there is nothing wrong with bringing good things to your own home.

At this moment, it was no longer time for Wang Xu to scold Academician Wang for planning projects for his family. He was not close to anyone.
