Reborn in 2005, starting with repairing mobile phones

Lin Dong looked at him for two seconds.

Then he nodded.

"it is good."

Just one word.

Zhang Mingyuan's heart sank back into his stomach. His benefactor had agreed.

"From now on, you'll work for me. My name is Lin Dong."

Lin Dong's tone was normal, showing no sign of excitement. "That 90,000 yuan is an advance from the company. It will be deducted from your salary gradually from now on."

Zhang Mingyuan quickly nodded, "Of course! Boss Lin!"

"If you encounter any technical difficulties or have any problems in your life, just tell me."

After saying this, Lin Dong leaned back and closed his eyes. "Don't talk now, just rest. We're meeting someone who works on software algorithms later, and you'll be working with him from now on."

"Yes!" Zhang Mingyuan replied in a low voice, immediately sitting up straight and not daring to make another sound.

His heart was in turmoil.

Working for Boss Lin... company advance payment... just say the word if you need anything...

These words reassured him more and more with each sentence. This was a proper arrangement; they treated him like one of their own.

He almost lost his life in the back alley of Guanlan, but from today onwards, he not only got his life back, but also found a place to live and had something to look forward to!

He took a quiet breath and looked out the window at the scenery rushing past. For the first time, he felt that this city wasn't so scary after all.

Beside him, Lin Dong had his eyes closed, his expression relaxed.

The matter was resolved.

The person has been accepted.

The first piece of the puzzle has been found.

The car drove smoothly towards Nanshan.

Lin Dong's mind had already switched to another channel.

Zhang Mingyuan is a good candidate, but having the talent alone is not enough; he also needs a design that allows him to showcase his abilities.

Next up is Zhou Chengyu.

He works on touch algorithms. We need to get him and Zhang Mingyuan to create some sparks.

He tapped his fingers lightly on his knees in a brisk rhythm.

We handled things one by one and dealt with people one by one.

This feels good. The car stopped near the Shenzhen campus of Harbin Institute of Technology.

Lin Dong didn't rush inside. He had Ah Hao park the car under the shade of a tree by the roadside. He rolled down the window, lit a cigarette, and his gaze fell on the college students coming and going at the school gate.

Young, energetic, with a light still shining in their eyes that hasn't been worn down by society.

Zhang Mingyuan sat to the side, looking a little awkward. This was his first time in a place like this; the air was filled with the smell of books, completely different from the familiar smell of machine oil and solder.

"Boss Lin,"

He asked in a low voice, "Is Dr. Zhou, whom we're meeting later, a university professor?"

"PhD student."

Lin Dong flicked his cigarette ash. "The touch algorithm guy, the boards you make in the future will depend on his code to function."

Zhang Mingyuan nodded, seemingly understanding but not quite. In his mind, writing code was something like fixing computers or making web pages, which didn't seem to have much to do with mobile phone tablets.

Lin Dong glanced at him and added, "Simply put, you're responsible for giving the phone a body, and he's responsible for making that body understand human speech and talk to it with his fingers."

Zhang Mingyuan understood what he meant.

Speaking with fingers.

He recalled the resistive touchscreen PDAs in the factory, which required poking with a fingernail or tapping with a pen, and were slow and often inaccurate. If only he could smoothly swipe with his finger...

The fire in his heart burned even brighter.

After finishing his cigarette, Lin Dong glanced at the time, then got out of the car.

"Walk."

Jingxin Tea House is located on a small street behind the campus. It has a small storefront and simple decorations.

Lin Dong requested the innermost private room.

He had Zhang Mingyuan sit near the door, while he himself sat in the main seat, facing the door.

"Just listen when they arrive."

Lin Dong said to Zhang Mingyuan, "But if I ask you about the hardware, just tell me the truth, and tell me as much as you know."

"Understood." Zhang Mingyuan nodded vigorously.

The appointment was for 3 o'clock.

At 2:58, there was a knock on the door of the private room.

"Please come in."

The door opened, and a tall, thin young man stood in the doorway.

He wore black-rimmed glasses, his white shirt was slightly gray, his hair was a bit messy, and his face showed the paleness of long hours of staying up late and an undeniable weariness.

It was Zhou Chengyu.

He glanced around the private room and paused noticeably when he saw Lin Dong in the main seat.

too young.

She sounds even younger than she does on the phone.

"Dr. Zhou, please have a seat."

Lin Dong stood up, gestured for him to enter, and smiled politely. "I am Lin Dong."

Zhou Chengyu snapped out of his daze, nodded, and sat down opposite him.

His posture was very stiff, the standard laboratory etiquette for receiving guests.

The waiter came in, poured the tea, and then left.

The private room fell silent.

Zhou Chengyu looked at Lin Dong, waiting for him to speak first.

In his experience, these "investors" or "bosses" would start by praising his academic qualifications and the reputation of Harbin Institute of Technology, and then make grand promises.

But Lin Dong did not.

He picked up his teacup, blew away the foam, and took a small sip.

Then he put down the cup, looked up at Zhou Chengyu, and his first words went straight to the heart of the matter:

"Dr. Zhou, isn't the multi-point trajectory prediction model based on adaptive Kalman filtering in your paper more than three times faster in terms of iterative convergence speed than traditional algorithms?"

Zhou Chengyu was startled.

I almost dropped the teacup in my hand.

He stared at Lin Dong with wide eyes, his lips moved, but no sound came out.

That paper… that paper that was blocked by the supervisor and hadn't even been publicly discussed in the lab! The most crucial algorithm improvement in it was this adaptive filtering model!

How did this person know?!

"How could you..." Zhou Chengyu's voice was dry.

"How would I know?"

Lin Dong smiled, a smile that carried a penetrating insight that seemed to see through everything. "Because if it were me, I would also start from there. The signal noise of a capacitive touchscreen is too random; traditional filtering either has a large delay or doesn't filter it cleanly enough. Your approach of dynamically adjusting the filtering parameters using real-time collected data is indeed clever."

Zhou Chengyu's breathing became rapid.

This is a true technical evaluation!

Moreover, the evaluation was so accurate, pointing directly to the essence of his algorithm!

His hands, resting on his knees, clenched slightly.

"but,"

Lin Dong changed the subject, his tone still calm, "No matter how beautiful the simulation data in the laboratory is, it is still just a simulation."

A true capacitive touchscreen, mounted under the LCD, has display noise; users' fingers are sweaty or oily; dry winters cause static electricity, and humid summers lead to accidental touches. In these real-world environments, can your algorithm still maintain three times the convergence speed?

Zhou Chengyu's expression changed.

This question touched on his most vulnerable spot.

His algorithm was invincible in a clean simulation environment, but once deployed on a real test board... its performance did suffer. This was one of the points his advisor criticized: "The theory is beautiful, but it's not practical."

"I..." Zhou Chengyu tried to explain.

Lin Dong didn't give him a chance.

"There's also the issue of accidental touches with the palm."

Lin Dong continued, tapping his fingers lightly on the table as if tapping a virtual phone screen. "With a large-screen phone, when you hold it with one hand, the edge of your palm will press against the screen."

How does your algorithm distinguish between a palm and fingers? If it makes a mistake, and a menu suddenly pops up while the user is typing, the experience will completely collapse.

Fine beads of sweat appeared on Zhou Chengyu's forehead.

These two problems are precisely the pain points he's been struggling with lately, yet hasn't found a perfect solution yet!

This young man in front of me not only knows his proudest achievement, but also sees through his weakest point at a glance!
