Chapter 151 Holiday
"...Let me give you an example. I have told Sister Li about this example before. Sister Chu, think about it, this is a missile."
Lu Yao held his chopsticks in the air.
Then the other hand picked up another fried bun:
"This is a satellite."
"Well, what then?"
"If the missile hits...for example, if it hits your cup of porridge, the satellite will send it the positioning of your cup of porridge and tell the missile where your cup of porridge is. As for the radio frequency chip, it is like a signal transceiver. , asking the question to the fried bun, that is, the satellite: Where is the porridge?
The satellite told it: The porridge is here, you go one kilometer to the left, then thirty meters to the right, and fall, yes, that's it. Here's how it works.
But...just imagine this signal as sound. The speed of sound propagation is limited. When I speak, you have to hear it before you can respond to me, right?
So, here comes the problem. An ordinary radio frequency chip asks the satellite where the coordinate signal is every time it speaks, and the satellite tells it the location of the porridge after hearing it. After hearing the missile, adjust its position. This goes back and forth, assuming it takes two seconds.
In these two seconds, it may be on the final landing point, because the time feedback of these two seconds will produce... an error of one hundred meters, for example. How did this error occur? ”
"It is generated because the missile asks the satellite and the satellite replies to it."
"Yes, but what if we shorten this process to 1 second, 0.5 seconds, or even 0.1 seconds? The missile asks the satellite where it is, and the satellite responds in 0.1 seconds. What will happen?"
"The error will be smaller...the missile will hit more accurately."
"That's right."
Seeing that she already understood the principle, Lu Yao nodded:
"This is the role of the radio frequency chip... Of course, this is just the simplest metaphor. In fact, if it is really used, it will have to deal with a lot of things, such as noise, signal strength, accuracy, etc. It is a huge and systematic integration, and what I am designing now is just such a... model. By inheriting multiple components to the model, it only takes a short time for the missile to ask where the satellite is, and the satellite to tell it. It takes 0.1 seconds...well, that's probably what it means."
This topic was started by Xu Ruochu.
When everyone was having breakfast together, she asked Lu Yao what she was doing and why her condition was so bad yesterday. When Lu Yao said, "I am making a large model of a radio frequency chip," she looked at her blank look. Examples given.
The working principle of the radio frequency chip mentioned by Lu Yao is very straightforward and easy to understand.
But...Xu Ruochu understood that the simpler things are, the more complicated they are.
After understanding what Lu Yao was doing, she couldn't help but ask:
"Is this difficult for you?"
"...It's difficult."
Lu Yao nodded again:
"This is just preliminary work. Let's put it this way, I am currently making a sketch. Only when the sketch is out can we make the actual object according to the drawing. The actual object will not work without the dimensions of the sketch. But the sketch is a step from the drawing. The process from 0 to 1, especially for this model, we cannot completely rely on the existing IB Some parts of the IS model need to be set up by yourself. So... all the parameters have to be recalibrated. All logical sequences have to start from 0. It is very complicated and requires a lot of work... and it is very brain-consuming. The main reason why I don’t remember anything you told me yesterday.”
Hearing this, Xu Ruochu nodded as if he understood, and asked again:
"Then why don't you ask someone else to help?"
"It's not necessary at this stage. If I find someone to help...the results won't be mine alone."
"Uh..."
Xu Ruochu was stunned.
I instantly understood what Lu Yao meant.
Couldn't help but look at Hu Li.
Hu Li lowered his head to eat without saying a word.
She already knew what her boyfriend was doing.
So now I only feel guilty.
Xu Ruochu thought for a while and asked:
"Then the application field of your chip model... is wide?"
"It's very wide. In the early stage, it will definitely be relatively...narrow, mainly for some special applications. But in the later stage, as long as it is made smaller, it will be normal to apply it to mobile phones as a navigation chip."
"Can it be used on mobile phones?"
"Yes."
"...So, the prospects are very bright. Can you apply for a patent?"
Hearing this, Lu Yao smiled and did not answer directly, but said:
"I haven't thought about it that much yet. Let's make it first and then see."
"...These are the contents of freshman year?"
"Of course not. If you really want to talk about it, these technologies... are actually only experienced in the graduate field."
Xu Ruochu was stunned.
I couldn’t help but ask:
"You mean..."
Lu Yao was happy.
Laughing quite easily:
"I am a genius."
"..."
Xu Ruochu was speechless.
But...she suddenly discovered one thing, that is, her former "assistant" no longer seemed to be hiding his clumsiness.
Lu Yao has always been a very reserved person.
This is her most intuitive impression.
He is determined at heart, but on the surface, he rarely argues with others. Even occasionally, Xu Ruochu would feel that when he was looking at something, his "posture" was aloof.
Like a knife hidden in a scabbard.
Those who are familiar with it can feel the sharpness of this knife. But people who are not familiar with it will just think that it is just an ordinary weapon.
But now...
Something is different.
She couldn't help but glance at Hu Li opposite.
He... is changing.
she said to herself.
……
After finishing the meal, Lu Yao was the first to get up and say goodbye.
There was no need for Hu Li to send it.
He took a taxi.
Hu Li had no intention of driving today and directly chose to take Xu Ruochu's car.
On the way to the company, Xu Ruochu thought about it and gave a suggestion:
"Xiaochen and the others are about to have a holiday."
"Well, what's wrong?"
Hu Li still didn't react.
Just listen to Xu Ruochu continue:
"Two days ago, he said that his teacher had given him final homework and he had a new computer at home."
Hu Li was stunned.
I instantly understood what she meant.
But his brows furrowed.
"...Do you also need a new computer at home?"
"?"
Xu Ruochu was speechless for a moment.
The heart says what are you talking about?
But Hu Li immediately adjusted the volume of the music, and when the singing became louder, he leaned close to her ear:
"I want to put Lu Yao's clothes at your house first. Let me use the second bedroom too. I can't put them at my house."
Suddenly, Xu Ruochu understood what she was thinking.
And if you think about it carefully...it's really the case.
To put it more objectively, there is no room in Sister Xiaoli’s house. After all, her house was only about a hundred square meters. Among the four bedrooms, the largest bedroom was converted into a practice room, while of the remaining three bedrooms, she slept in the smallest one, and the other two had walls removed and turned into cloakrooms. Even if she really wants to get a computer, her house is too small and can only be placed in the living room.
What's more... the best situation for her family now is that she has nothing.
It is best not to have any trace of Lu Yao.
Just as he was about to agree, Hu Li continued:
"I plan to buy another apartment under Lu Yao's name, which will be more convenient."
"...Still here?"
"Yeah."
Hearing this, Xu Ruochu thought for a while and shook his head:
"I'll do it. Give it to him. It has nothing to do with you."
"Okay. But it takes time to decorate, and it also takes time to put in the smell. So put his things with you first."
"Yeah, okay."
With just a few words between the two of them, under Lu Yao's name, there may be an additional property in the next few days...
But he didn't know all this clearly.
After returning to school in the morning, he got time for the exam.
The final exams for the freshman year in the Department of Electronics will begin one after another starting tomorrow.
When Yu Kun told him, he nodded indifferently.
For him, the freshman exam is almost like one plus one in elementary school.
But for others in 305, it is obviously a big break.
Liu Mingze didn't even play the game anymore... Fortunately, the World of Warcraft Arena season was over, and Shen Yi finally got the gladiator dragon that he had longed for.
Xu Ruochen even got one for the mage number given to Lu Yao.
It's a pity that he hasn't logged in a few times this semester. He usually switches between Xu Gongzi and Liu Mingze.
But in the final analysis, Lu Yao, who had been busy for many days, could finally rest.
On the 11th, people from 305 burned incense and worshiped Buddha early in the morning, burned incense and bathed, praying that they would pass the exam... In fact, the other three were more confident in themselves, but Yu Kun's grades were not very good.
He wanted to "change jobs" more than once this semester.
I was tricked by my teacher into studying electronic engineering, but after half a semester I still had no idea about these things.
Fortunately, Lu Yao helped him with extra lessons these two days.
As for how much you can listen to, how much you can listen to, whether you failed the exam or not... you will only know after the results come out.
In the morning, Lu Yao sat in the examination room under the curious eyes of his classmates.
【1. Among semiconductor materials, what kind of element is doped in N-type semiconductor?
A, Boron (B)
B, Phosphorus (P)
C, Arsenic (AS)
D, germanium (GE)】
He yawned lazily...
Um.
The level of difficulty is not as good as that of primary school students.
...The beginning of the final exam represents the end of the first half of the freshman year.
Everyone packed up and got ready to go home.
The subjects of the examination are different according to the course schedule, and the time is naturally different and very scattered. But the pressure of schoolwork was there, and Lu Yao didn't know if it was an illusion. He always felt that even the usual yelling and screaming in the dormitory were much quieter during this period of time.
People who didn't know it thought it was the college entrance examination.
In a few days, as the results came out one after another, Lu Yao's scores were perfect in every subject.
Got all the grade points.
But Young Master Yu was in tragedy. Linear algebra failed directly, and it was a miserable death.
After all... Lu Yao was speechless.
How can you fail the most basic thing like linear algebra?
If you can pass this exam, how did you get into Fuhua?
But... there is really nothing you can do about failing a class, just retake it. Reviewing a winter vacation, as long as the start of school is over, it is over.
As for not being able to pass...the coursework is yours, then there's really nothing you can do about it.
The things taught in freshman year are all extremely basic. If you find even these difficult, then Lao Yu may have made a mistake.
Check out the 16-9 book bar and see the correct version!
After the exam, the school will prepare for the holiday.
Before the holiday, Lu Yao was pulled by Mr. Xu and came to Xinsuo again.
However, his condition this time is obviously much better than last time, at least he is not "perfunctory" anymore.
I officially recorded "Flowers", and then re-recorded the demos of the other three songs.
Mr. Xu didn't mention the cost, but several people knew it. Even Wei Qianqian said that all the proceeds from the album would belong to him... But Mr. Xu waved his hands indifferently, feeling that it was not necessary at all.
With the final version confirmed, "Flowers" has finally landed on the music platforms of Kugou and Kuwo, despite the long-awaited release.
But to put it bluntly, there is currently no profit.
It’s free for everyone to listen to.
If you really want to make money, you have to wait for the album to be produced and then make a profit by selling the album.
So, after the audio source landed on the platform, Wei Qianqian went to Lu Yao to talk about this matter.
The meaning is very simple:
"For a band like ours that is not signed by a company...if we don't release an album, Xu Ruochen will keep asking for money. We give it to him, but he doesn't want it. It's not appropriate."
"Got it."
Lu Yao, who was about to go back to the dormitory to pack his luggage for the holidays, nodded:
"Give me a holiday and I'll make up seven to eight songs. I've been busy with my own affairs recently and I really don't have time."
"Okay. Then... if someone asks us for a business performance, will you accept it?"
Lu Yao was a little surprised when he heard the squad leader's words:
"Someone is looking for us now?"
"Yes, but they are all of a corporate nature. They want to sign a contract with us. What I mean is...if I can contact some bars or performances, do you want to participate?"
"Uh...have you asked anyone else?"
"Not yet."
"I'm fine with it, but you have to tell me in advance. If other people don't have any objections, then it's definitely OK."
"Okay."
Lu Yao agreed, and Wei Qianqian felt at ease. After all, during this period, no one really paid a penny whether it was recording songs or Teacher Wu. Even... after Teacher Wu got the demos of those three songs, he liked them very much and spent this time "helping" in the production.
But she understands the connection between helping and money, so she doesn't want to do this.
Who knows... Lu Yao made it clear, but when she communicated this matter with Xu Ruochen, she received "firm" opposition:
"No, forget about commercial performances. Unless it's a large-scale rock festival, or it's the same song... If I go to a commercial performance where you just pay me, monitor, do you believe that my father will take my Broken leg?”
"Uh..."
Wei Qianqian felt a little ridiculous.
Also "Same Song"...the same song can be played as soon as you ask?
But the rejection of the "big benefactor" made her "business blueprint" come to an end.
This matter can only be dropped temporarily.
But the good news is... "Flowers" seems to be really taking off.
Within a few days of being logged into the Kuwo Music Box, it had already entered the top 50 of the Kuwo Music Chart.
This result... is quite incredible.
Although there is no source of income, it shows one thing, that is... a lot of people listen to this song.
Everyone loved it.
The band No One Survived has jumped into the eyes of many people at this juncture of the end of the term.
Although this song has not reached the level of being sung in the streets like "Love Transfer" and "Little Lucky", it has made it into the top 50 in the pop music charts. As a rock band, this achievement is It’s already quite outrageous.
Even, in Wu Mengqi’s words:
"Qianqian, if you can sign the contract... take advantage of the popularity and make sure you get up."
Indeed.
Kuwo and Kugou are currently the largest music platforms on the Internet, and music charts have always been a battleground for all singers. A band composed of college students ranked among the top 50 with just one song. This achievement is truly incredible. At this time, as long as they can sign a contract with a company, no matter what company it is, they will spare no effort to promote it.
It's a pity... they didn't sign the contract at all.
Not to mention what Wu Mengqi said, Chen Pu also approached people from Xinsuo and wondered if he could talk to the band through the relationship between guitarist Xu Ruochen.
As a result... the people from Xinsuo ignored Chen Pu at all.
It's not that they looked down on Chen Pu, but simply that Chen Haiwen suppressed him after hearing this.
Sign the eldest son of the Xu family to be a singer?
Doesn't that mean taking the initiative to find the Lord of Hell?
You are not afraid of death, I am still.
Therefore, a strange phenomenon occurred.
Obviously on the two platforms Kugou and Kuwo, the song "Flowers" has achieved very good results.
But... no one gave birth to a child, and the band had a quiet time.
Firstly, there are no commercial performances, and secondly... there are no rock festivals in the winter in China.
And they don’t even have an agent.
No one cares at all...
Anyway.
Anyway, as time gets closer to the New Year, on January 17th, Fuhua finally ushered in the winter vacation.
The people from 305 went out to have a meal together, and then went their separate ways without any intention of distinguishing themselves.
Yu Kun and Liu Mingze both left in time in the morning. When Lu Yao woke up, there was no one in the dormitory.
He was not in a hurry and started to dismantle his computer.
Just as I was cleaning up, the door was pushed open.
Xu Ruochen and Xue Mingyue walked in front and back.
Lu Yao was speechless:
"How did you come in?"
"You walked in."
Xue Mingyue said with a smile.
Lu Yao thought to himself that those two bottles of Maotai and Two Chinese were really exciting. This dormitory building has almost become Mr. Xu’s home.
Bring in whoever you say you want to bring in.
"Are you free tonight?"
Xu Ruochen pulled the suitcase out of the cabinet and handed it to Xue Mingyue, then sat on the chair and asked.
Xue Mingyue began to help pack his clothes.
"No. Go home and continue to suffer."
"...You don't even take a break during the holidays?"
"Never stop, try to get it done before the end of next semester. It's urgent."
"That's...ok."
Seeing his firm tone, Xu Ruochen felt a little regretful.
He originally wanted to take Lu Yao out to play together.
But he also understood why Lu Yao was like this, so it was rare that he didn't pull him by force this time.
After Xue Mingyue heard this, she glanced at Lu Yao, said nothing, and continued busy.
In fact, during this period, Shen Wan has been asking about Lu Yao's news from her.
After one semester of contact, Xue Mingyue also learned from Mr. Xu what kind of virtue Lu Yao was when he was busy, but he also admired it... It is really rare to see such a dedicated person.
But now after hearing this news and telling Shen Wan, it was another favor.
Just like that, when Lu Yao had almost packed his things, his phone rang.
When he saw the caller, he was stunned for a moment, and then showed Mr. Xu a look at the screen.
Mr. Xu was speechless when he saw it clearly.
Because the caller... was my sister.
"Hey, Sister Chu."
"Are you busy?"
"No, I'm packing my things to go home. It's a holiday."
"So, you are awake now, right?"
"Yes."
"Okay, come find me in the afternoon and go to a cocktail party with me in the evening."
"Uh... Okay, I understand, I will contact you that afternoon."
"Well, hung up."
After hanging up the phone, Lu Yao said to Xu Ruochen:
"Sister Chu asked me to attend a cocktail party."
"..."
Mr. Xu was speechless and looked at Lu Yao with an "unkind" look in his eyes.
Grandma's.
This scumbag deserves to be beaten!
"I'll strangle you!!!"
"Cough cough cough..."
On the side, Xue Mingyue, who was helping Xu Ruochen tidy up her clothes, looked at the two of them having fun, and her temperament, which she didn't know why, seemed to be peaceful over the years.
Um.
Very good.
