When Chen Zhu's father came back, the garage was almost finished.
The middle-aged man was pushing a motorcycle, sluggishly standing under the streetlight.
"Chen Zhu's father!" Lin Zhaoxi noticed it first, and waved a rag to greet him.
"Lin Zhaoxi, why are you here?" Old Chen hurriedly stopped the car and walked over, his face blushed when he saw the brand-new garage.
"Learn from Lei Feng on March 5." Lin Zhaoxi said with a smile.
"Uncle, don't listen to her nonsense! We wanted to use a computer, and then Chen Zhu said that you have it, so we wanted to sort it out and see if we could build a few. I'm really sorry that I didn't tell you." Lu Zhihao said He bowed, with ashes on his face, and a very sincere attitude.
"It's okay, you can use it, you can use it." Old Chen hurriedly said, thinking about it was wrong, and asked, "But how do you organize it? How about I call Chen Zhu's uncle over this weekend?"
"No need." Chen Zhu emerged from behind the shelf in the garage, pointing to Pei Zhi who was working under the lamp.
There were many disassembled computer circuit boards piled up on the old table in the garage. Pei Zhi stood in front of the table and inspected the assembled "computer".
Hmm... if that thing can be called a computer...
The circuit board is completely exposed, not installed in the case, and it looks suspicious anyway.
"This can be used without a shell?" Lao Chen then asked.
"In theory, yes." Pei Zhi added to ensure the accuracy of the answer, "but if the circuit board is damaged, it's hard to say."
"Try it!" Lin Zhaoxi said with a smile.
Pei Zhi nodded, found a video cable, and connected the "computer" with the monitor. Everyone held their breath, the screen lit up, and the characters slowly appeared...
In the garage, the exclamations of Chen Zhu and his father echoed.
When the few of them saw the computer turned on, Lu Zhihao rubbed the ashes on his face, Hanamaki continued to put things, she twisted the dirty rag into the bucket, and she didn't feel anything strange at all.
"Young man, it's amazing." Old Chen patted Pei Zhi's shoulder vigorously.
"The hardware knowledge is relatively basic, and it is enough to figure out the model adaptation." Pei Zhi said.
"Routine operation." Hanamaki grabbed the white.
Old Chen was stunned, not knowing how to answer.
"Uncle, do you still want these things?" Lin Zhaoxi smiled and asked him, pointing to a large pile of cardboard shells that had been packed up.
Lao Chen was very embarrassed: "It's all useless things, and I haven't taken them to throw away."
"I see there is a scrap yard at the door, shall we sell it?"
"Okay."
After hearing what Old Chen said, Lin Zhaoxi picked up a pile of cardboard and put it on his shoulders.
"Uncle is here to carry, Chen Zhu is here to help, how can we let the girl carry the things?" Old Chen hurried over to grab it.
But before Lin Zhaoxi had time to say anything, she heard Lu Zhihao say, "She has great strength."
"Eat a lot." Hanamaki said.
"It's okay." This is Pei Zhi.
Chen Zhu remained motionless, his behavior explained everything.
Lin Zhaoxi: "..."
—
Old Chen still felt embarrassed, but the children said so, so he could only do good.
It was completely dark, and many street lights in the community were broken.
It was still a bit cold, Lin Zhaoxi sneezed, and then realized that the surroundings were very quiet. She and Lao Chen came all the way without talking.
Lin Zhaoxi looked at Old Chen.
Old Chen said, "You two have a really good relationship."
This sentence is a bit light, it's like talking casually when you can't find a topic, it seems a bit embarrassing now.
"We were classmates in elementary school and went to a junior high school," she said.
"No wonder, Chen Zhu said that you all have good grades." Old Chen paused, and said, "Chen Zhu didn't have many friends before. You can play with him and take him to study. Thank you."
"we help each other!"
Lin Chaoxi was afraid that Lao Chen would thank her again for the winter vacation cram school, so she interrupted quickly.
What's more, when they first met Chen Zhu, it was purely because she wanted to find a black Internet cafe to surf the Internet...
"If there is anything uncle can help, just tell me directly." Chen Zhu's father said sincerely, probably for him, he couldn't find any other way to express his gratitude.
"Then I really mentioned it?" Lin Zhaoxi stood still and said shamelessly, "Can you increase the speed of your broadband at home, we want to come to your home to surf the Internet in the future..."
"It's definitely no problem." Old Chen patted his chest, "With you guys monitoring Chen Zhu's Internet access, I feel more at ease!"
Old Chen cheerfully carried the cardboard and continued to move forward. When he was about to reach the entrance of the new village, the excitement outside came in. Lin Zhaoxi looked at Old Chen's back and stopped. She didn't know where the courage came from, and she said: "Uncle , there is actually one more thing!"
Old Chen stopped in his tracks. He hadn't changed his traffic police uniform yet, his face was tired and haggard, but he was also very upright and handsome.
"What's up?"
"I want some traffic data in the city. I don't know if it is possible."
—
It is Lin Zhaoxi's current idea to prevent Lao Lin's car accident through some kind of algorithm.
But what is the specific algorithm and how to calculate it, she actually doesn't have much direction. One is that it involves too much mathematics and programming knowledge, and the other is that there is a great distance between her and these knowledge.
But no matter what, she knows that big data will always be the basis for any predictive algorithm. The remaining two are mathematics and computers.
She made the request to Chen Zhu's father a bit too early and seemed abrupt, but Lin Zhaoxi asked out of nowhere.
It's like a fate in the dark. At the beginning, Lao Chen was busy with Lao Lin's car accident. Now that he does it again, there must be a different ending.
Lao Chen didn't agree to her immediately.
Carrying the cardboard, he put it on the scale at the waste station with some puzzlement, and then asked him, "What kind of traffic data?"
"The records of car accidents over the years, the data of traffic flow and pedestrian flow on the road, and..." These problems are caused by the lack of knowledge reserves. When Lin Zhaoxi said this, she didn't know what else she wanted.
"I can't tell you about the car accident information. Who hit who and what happened to whom? These are other people's privacy." Lao Chen hurriedly said, "And you have car accidents over the years? On our Zhongshan Road, there will be many accidents in one day. Big and small car accidents…”
"I don't want those details." Lin Zhaoxi waved his hand, "As long as the data, our city must submit reports to the higher authorities every year, how many car accidents, casualties..."
When Lin Zhaoxi said this, Lao Chen's face darkened: "What do you want these things for?"
The scrap stall owner also looked at her strangely, his eyes burning under the lamp.
Lin Zhaoxi felt that it was not only about studying, but making up excuses was also very difficult and required talent.
She thought about it seriously, and in the end she didn't make up too much of an excuse.
"There's someone very, very important to me who's been in a car accident before..."
Hearing this, Lao Chen's eyes instantly softened, and the waste stall owner looked at her lovingly, and even the boys in the shop put down their work and waited for her to continue talking.
"So I want to see if there is any way to prevent car accidents like preventing diseases." Lin Zhaoxi said.
Old Chen was stunned, as if he thought it was too much to ask the bottom line just now, but as a traffic policeman, he subconsciously asked, "How can this be prevented?"
Lin Zhaoxi thought for a while and said, "When we are walking on the highway, there are not often warning signs saying that a certain place is 'a high-risk area of traffic accidents, please drive carefully'."
"Yes, but what you said is different."
"Calculating the location of accidents on a certain road section and issuing warnings is the simplest application of mathematical statistics in traffic. Then, to predict and prevent traffic accidents means to introduce more data and adopt more sophisticated data processing methods."
"How to deal with this?"
"I really don't know, I just have an idea."
"You are still so young, why do you think about such a difficult thing?" Old Chen didn't ask any more questions, and his eyes suddenly felt guilty.
After a while, he sighed, patted her shoulder heavily, and asked, "Is that your mother?"
Lin Zhaoxi also felt inexplicably sad at first, because the matter she said was too difficult and hopeless, but Lao Chen's question made her suddenly feel like laughing.
Of course not her mother, she has never had a mother.
But it’s okay without a mother. She has grown up healthy and can try to do things that seem extremely unrealistic.
no big deal.
"Can you keep it a secret for me?" She took a deep breath, raised her head and said to Chen Zhu's father, "They don't even know."
