Xueba's computing system

Chapter 28 Goal
Lin Yuan took Da Zhang's phone and connected it to the USB port of the laptop with a Type-C data cable. Then he clicked on the version information to open the hidden developer mode, and then turned on the permission to debug via USB.

"Hey~~, why does my phone have this function?" Da Zhang was very curious when he saw that his phone had an extra function.

“This is a hidden feature of Android phones.”

"You're amazing. You even know this. No wonder you were able to get into graduate school."

In fact, turning on the developer mode of an Android phone is a very basic operation for IT personnel.

In just two or three minutes, Lin Yuan installed a small software.

"Here you go." Lin Yuan handed the phone back to the other party, "You're still delivering food this afternoon, right?"

"I have to deliver during the evening rush hour. Otherwise I will go home empty-handed today and my wife will be furious with me."

"Then you can uninstall my newly installed little software tomorrow."

"Why did you install this thing? I'm just asking out of curiosity. Anyway, I don't have anything valuable on my phone, so it's okay to keep it installed and not uninstall it."

"It is to collect your food delivery itinerary and fill in the data when writing the test report for the company."

Lin Yuan installed this small software to collect the delivery trips of the riders, but it was obviously not for filling in the data when writing reports. He naturally wanted to pass the data to the computing system and let the computing system collect the riders' data.

But it was definitely not convenient for Lin Yuan to reveal too much to Da Zhang, so he just found an excuse to get away with it.

Lin Yuan wrote this small software in about an hour while waiting for Da Zhang. Since the function of this software is very simple, it is just a small application that reports the location information of the mobile phone at intervals. Therefore, Lin Yuan finished writing it in a short time.

This was inspired by the way the computing system could establish data with merchants through cameras. According to his idea, the delivery trajectory of each rider could be obtained through mobile phone positioning.

When each rider picks up the meal and when it arrives at the destination can be determined through the mobile phone positioning information and the merchant information obtained by the system.

Lin Yuan's small software does not steal data directly from the food delivery app on the rider's mobile phone through hacking means. Lin Yuan currently does not have the ability to steal such data, and the system does not show any signs of cooperating with him to carry out such illegal activities.

Therefore, Lin Yuan could only settle for the second best and try to find a way to obtain the riders' movement trajectories.

The riders’ trajectory data is naturally not as detailed as the actual food delivery data, but the time of pick-up and delivery can be determined by the length of time they stay at each place and the speed of their movement.

For example, if the rider goes to the store, he must be picking up the food. If the rider's average speed is more than 10 yards per hour, he must be delivering the food. If the rider's average speed is less than 5 yards per hour, he is probably delivering the food on foot after arriving at the destination.

This logic is not complicated, and Lin Yuan believes that the computing power system must have made the judgment.

Of course, it is useless to install this small software only for Da Zhang, the rider. Only after most of the riders in this area have installed it, can rich and detailed data be collected. But Lin Yuan must first verify whether his conjecture is feasible.

So he invited Da Zhang to dinner, both to reminisce about the past and to ask Da Zhang to do him a small favor.

After Lin Yuan put away his notebook, he also started eating with his chopsticks.

The steam from the hot pot filled the space between the two of them. From time to time, the waiter would come over to collect the empty plates, or ask in a low voice if there was anything they needed.

Da Zhang was sweating profusely while eating, and it looked like he was enjoying it.

"Oh, the tripe here is much better than the buffet hotpot."

Lin Yuan smiled, then silently scanned the code with his phone to order another portion of tripe. The tripe here was naturally much fresher than the unlimited supply of shredded frozen tripe in the self-service hot pot restaurant.

"Lin Yuan, are you getting paid for your internship? Are food and accommodation provided?"

“Food and lodging are not included.”

"Then you have to pay a lot of money to rent a house. You can't live in the old shabby house when you work in a place like that."

"The company provides housing subsidies. And I now live in the school dormitory, in a double room. It only costs 2000 yuan a year." In fact, because school has not officially started yet, Lin Yuan has not even paid the 2000 yuan.

"How much is your rental subsidy?"

"3000 yuan, collected once every two weeks."

"What?" Da Zhang shouted, startling the diners at the next table. "3000 for half a month, so your monthly housing allowance is 6000?"

Lin Yuan nodded. "This doesn't include wages?"

Lin Yuan nodded again. In fact, this did not include the several hundred yuan commuting subsidy.

Da Zhang's hand picking up the chopsticks was obviously much slower. After a long while, he managed to say, "It seems that graduate students are still popular."

If Da Zhang hadn't asked, Lin Yuan would not have wanted to talk about his income, because the income gap between them had already widened, and talking about it would only embarrass others.

Da Zhang continued, "It seems that my child will have to take the postgraduate entrance examination in the future."

Lin Yuan didn't want to give Da Zhang the illusion that passing the postgraduate exam would lead to a good job, because for the postgraduates at his alma mater, it was really useless to pass the exam, it was just a waste of three years.

"It's not just about the degree, it's mainly about the school." Lin Yuan immediately corrected the other party.

"Then the aviation school you are in now must be quite good."

"Well, it's alright."

"Then my child will apply to your school in the future. If you can get in, my child can definitely get in too."

Lin Yuan could only smile and said, "Then you have to ask your child to work hard." Lin Yuan tried his best not to look embarrassed.

Da Zhang’s views are very simple.

Lin Yuan is a delivery man. Lin Yuan was admitted to the aviation school.

I am also a delivery man. I chose the wrong path and that is why I didn't know how to study. If my son studies hard, he will be able to get into the aviation school.

The relationship in this formula is: Lin Yuan == deliveryman 《==》 deliveryman == Da Zhang == son.

Da Zhang uses the delivery job as a bridge, believing that his son will be able to be admitted to the aviation school in the future, provided that he does not give up like Lin Yuan and insists on studying hard.

This made Lin Yuan feel like he was in a dilemma whether to persuade her or not.

Finally, Lin Yuan thought about it. If Da Zhang could encourage his children to study hard in the future, it wouldn't be a bad thing. So he just went with the flow and skipped the topic.

"Almost done, I have to go deliver the food."

"Ah? Are you still going at this time?"

"You can even catch the tail end of the lunch rush."

"Why are you in such a hurry? There are still a lot of dishes."

"I have to save money for my child to enroll in tutoring classes."

Da Zhang is an impatient person. When he saw Lin Yuan's successful case, he wanted to implement it immediately.

Even after saying goodbye to Lin Yuan, he turned around and called his wife.

Da Zhang's voice was so loud that Lin Yuan could still hear it from a few tables away. "Wife, how much does that tutoring class you mentioned cost? Hurry up and sign up. I'm telling you..."

As Da Zhang's voice gradually faded, Lin Yuan smiled bitterly as he watched the other person disappear at the door.

Da Zhang was originally in a lazy and slack mood, but he cheered up in a moment after seeing that his child had a hope of changing his fate.

Sometimes, maybe you can't really blame them for being lazy. To make people work hard, they must first have a visible goal.

Whether this goal is realistic is another question.

Lin Yuan took a few more bites and then put down his chopsticks.

Since Da Zhang went to deliver the takeaway, he could log in to the cloud server to check the collected data.
