Chapter 42 I'm going to the rooftop to cool off.
"Who's so well-mannered this early in the morning?"
"Click".
The doorknob turned, and the laboratory door was pushed open.
Li Hongde walked at the front, carrying lesson plans, followed by Sun Hao carrying steamed buns and Zhao Pengfei carrying soy milk.
The three of them had obviously bumped into each other in the cafeteria downstairs and came up together.
As soon as the door opened, it bumped right into Zhou Mingyuan, whose steps were unsteady and whose eyes were vacant.
"What's all this howling and wailing so early in the morning?" Li Hongde frowned.
Zhou Mingyuan stared blankly at Li Hongde, his lips trembling, but he couldn't utter a single word.
He turned his head and took a deep look at Lu Feng, who was sitting in front of the computer drinking water, before silently turning away.
"Teacher, I'm going to the rooftop to cool off for a while."
After saying that, Zhou Mingyuan staggered out of the laboratory and closed the door behind him.
Sun Hao, with a steamed bun in his mouth, stared blankly at the closed door and asked indistinctly, "What's wrong with Brother Zhou? Did you stay up all night watching the game and mess up your brain?"
Zhao Pengfei took a sip of soy milk and shook his head: "I guess it crashed and blue-screened again while running the data. He was complaining yesterday about how difficult that set of non-stationary noise data was."
Li Hongde ignored the two clowns.
He knew Zhou Mingyuan too well. Although the kid seemed unreliable at times, he had an extremely strong mental fortitude. At most, he would curse a couple of times at the slightest setback.
Li Hongde's gaze passed over the long table and landed on Lu Feng, who was sitting by the window.
This kid arrived earlier than anyone else today, and he was sitting in Zhou Mingyuan's newly built top-of-the-line desktop computer.
Li Hongde's intuition told him that Zhou Mingyuan's unusual behavior was 100% related to Lu Feng.
He threw the lesson plan on the table and walked behind Lu Feng.
"What did you do? Why did you provoke Mingyuan like this?" Li Hongde's tone was calm, but his eyes were already fixed on the screen.
Lu Feng put down his water glass, turned around, and said calmly, "I didn't do anything, just helped Senior Brother Zhou process the data he didn't finish yesterday."
"You're helping him process the data?" Sun Hao asked, munching on a steamed bun as he leaned closer.
"Old Zhou's data was just collected from the No. 3 experimental platform, with 450,000 sampling points, full of high-frequency glitches. He spent an afternoon writing a filtering script in MATLAB, which takes half an hour to run once."
Zhao Pengfei nodded in agreement: "With that amount of data, the fan on this new computer will have to spin like crazy to run it."
Lu Feng didn't explain, but held the mouse in his right hand and clicked a few times on the screen.
"Teacher, senior brother, look!"
He closed the newly generated processing report and brought up the rudimentary gray interface called "University Data Sauce" again.
Import data.
"Check the boxes for wavelet noise reduction and fast Fourier transform".
"run."
Lu Feng's movements were fluid and graceful.
Before Sun Hao could even swallow the bun in his mouth, the green progress bar in the center of the screen suddenly filled up.
"drop."
A crisp notification sound rang out, and two extremely clear charts instantly appeared in the blank area on the right.
The time-domain waveform is incredibly smooth, and the resonant peaks in the frequency-domain spectrum are precisely labeled. A detailed text report of the characteristic parameters is also included below.
two seconds.
The entire process takes no more than two seconds.
Sun Hao's mouth opened slightly, and half of the bun fell to the ground with a "thud," rolling around and getting covered in dust.
Zhao Pengfei tilted the soy milk cup in his hand, spilling the milky white liquid onto the back of his hand, but he was completely unaware.
Li Hongde's pupils contracted.
He has been deeply involved in the field of mechanical dynamics for decades and has worked with countless data processing software, including commercial, open-source, and self-developed software.
But he swore he had never seen anything processed so quickly.
"What... software is this?" Li Hongde's voice was unusually dry.
"I wrote it myself." Lu Feng leaned back in his chair, his tone as casual as if he were commenting on the weather. "I was bored in my dorm last night, so I just typed it out."
"You wrote this yourself?!" Sun Hao suddenly raised his voice, his voice so sharp it almost cracked.
Zhao Pengfei hurriedly put down the soy milk cup, grabbed a few tissues to wipe his hands haphazardly, and stared intently at the simple gray interface.
"Junior, you must be joking! You're a freshman in mechanical engineering, and you wrote a data processing program in one night that can beat MATLAB? How did you write the underlying logic?"
"The underlying system still uses a C-compiled math library," Lu Feng explained casually. "I just wrapped it in Python, rewrote the data retrieval logic, and utilized multithreading. MATLAB is too bloated, with many background services consuming excessive computing power. I cut out all the useless stuff and focused on the core algorithms."
Li Hongde bent down, placed his hands on the edge of the computer desk, and sharply scanned the few lines of Python source code that were still on the screen.
The code structure is extremely concise, with no redundant loops, and memory allocation is accurate to the byte level.
This is something a beginner simply couldn't write. It requires an incredibly strong grasp of computer architecture, data structures, and advanced mathematical algorithms.
Li Hongde straightened up, took a deep breath, and suppressed the turmoil in his heart.
When did you start learning programming?
"I just learned it last night," Lu Feng answered truthfully.
Sun Hao rolled his eyes and clutched his chest.
He felt he shouldn't have asked. Being in a lab with such a monster would only shorten his lifespan sooner or later.
Li Hongde stared at Lu Feng for a full five seconds, and after confirming that the kid wasn't joking, his brows furrowed slightly.
"Why did you suddenly decide to get into this? Aren't mechanical dynamics and materials science enough for you to study?"
Lu Feng shrugged, his tone rather helpless: "Just playing around. It's mainly because Professor Ye Guodong asked me yesterday to lead the team in the provincial college student mathematical modeling competition. That competition has high requirements for programming and data processing, and I figured I couldn't hold them back, so I learned a bit on the side."
"Ye Guodong?"
Upon hearing this name, Li Hongde's face instantly darkened, and he let out a cold snort.
"That old bastard, he's got his hands on things way too far!"
Lu Feng was somewhat surprised: "Teacher, do you know Teacher Ye?"
"Know him? He's more than just someone I know!" Li Hongdela pulled up a chair and sat down, saying irritably, "Back when we were undergraduates at Yenching University, he slept in the bunk below me!"
Sun Hao and Zhao Pengfei exchanged a glance, then quickly looked away, pretending they hadn't heard anything.
These kinds of old, dark stories between big shots are not something they can hear.
"They borrowed my people to play in their math department's competition without even telling me?!"
Lu Feng found it amusing to look at Li Hongde's protective attitude.
"Teacher, there's actually no harm in participating," Lu Feng advised. "Mathematical modeling is a great opportunity to develop logical thinking skills, and it will also be helpful for our future research projects."
Li Hongde glanced at him, his expression softening slightly: "Alright, but since you've decided to participate, then compete well and don't embarrass our School of Mechanical Engineering."
