Chapter 181: Threshold and Margin

The progress bar hit 100%. The terminal flashed green: Done. Output saved to /tmp/result_8000.csv. The roar of the case fans gradually subsided, like water stains left on the beach after the tide receded. Lin Chen released the Enter key, a thin layer of sweat coating his fingertips. He pulled out the USB drive and turned the screen toward the opposite side of the conference table.

Director Li didn’t look at the result file first. He opened the logs instead. He dragged the scroll bar to the bottom: exception capture records, markers for skipped dirty data, time-consumption statistics for chunked reads, peak memory comparisons before and after garbage collection. He read for about two minutes, then tapped his fingers lightly on the desk twice.

“Memory overflow is the norm. Running new logic on old hardware, nine out of ten people just yank the power cord and start over. You used three lines of code as a safety net.” He closed his laptop, his gaze settling on Lin Chen’s face. “But a production environment won’t give you the chance to patch code on the fly. Did you run stress tests before deployment?”

“No. Only a local virtual machine.” Lin Chen’s voice was steady. “Stress testing requires a cluster, which I can’t afford to rent. So I hardcoded the degradation threshold into the configuration. I’d rather drop edge-case fields than let the process hang. The business wants results, not a perfect process.”

Director Li nodded and pulled a printed form from his drawer. The paper edges were curled, bearing the marks of repeated photocopying. “The provincial capital branch is expanding this year, hiring two backend interns. Base salary six thousand, eighty percent during probation. No housing provided, three hundred for meals. One day off per week. During project phases, you follow the iteration schedule; clocking out at 2 AM is routine.” He pushed the form across the table, his fingertip resting on the salary column. “Can your current state handle it?”

Lin Chen’s eyes fell on the form. Six thousand. After deducting social security and the rent for a single room in an urban village, he’d have a little over four thousand left. Enough for three months of his brother’s sodium valproate, enough for next semester’s textbooks, with a small buffer left for emergencies. But he didn’t answer immediately. He glanced down at his left foot. Beneath his pant leg, the ankle was swollen and shiny, the shoelace cutting into the flesh, a dark red blood stain seeping through the sock cuff. He needed the money, but he couldn’t afford to burn his body out to get it.

“Yes,” he said. “But I need two things clarified. First, the probation evaluation criteria: is it based on code commit volume or online bug rate? Second, if we’re pulling consecutive all-nighters during project phases, is there compensatory time off or a transport subsidy?”

Director Li smiled, faintly, fine lines crowding the corners of his eyes. “First second-tier college graduate to negotiate evaluation metrics with me. The standard is simple: independently handle a module, don’t drag down the main timeline. No comp time, but taxi fares are reimbursed. The tech sector doesn’t coddle slackers, and it doesn’t deal in sentimentality. Take it, report next Monday. Don’t, turn right out the door and hit the job market.”

Lin Chen picked up the pen on the table. The tip hovered over the signature line. He ran a quick mental ledger: a balance of 7,135.30 yuan, the estimated cost of a slow train to Shenzhen, the dorm lease deposit, his brother’s medication for next month, and the outstanding balance from Old Zhao. The money looked like it was sitting in the account, but every single yuan was already earmarked for future expenses. He signed his name. The handwriting was steady, without a single cursive stroke.

“Next Monday, 9 AM.” He pushed the form back.

Director Li took the form and handed him a blue access card. “Register at the front desk. Once you’re back, send me the score acknowledgment for this morning’s practical test. The company doesn’t hire people who leave loose ends.”

Lin Chen stood up. The moment his left foot hit the ground, a sharp pain shot from his sole to his calf, the muscle spasming uncontrollably. He bit down on his molars and made no sound. His gait was slightly uneven, but his rhythm didn’t break. He pushed open the door to Room 302. The corridor’s air conditioning hit him in the face, carrying the smell of old carpet and printer toner. Beyond the glass curtain wall, the afternoon light was slanting west, the clouds pressing low like a waterlogged gray cloth.

The elevator descended. He was alone in the metal car. He leaned against the handrail and closed his eyes. His breathing slowly steadied. He knew that signing the paper wasn’t the finish line; it was an entryway into another set of rules. Six thousand bought an admission ticket, not security. He had to vacate the dorm, treat his foot, and wrap up the practical exam before Monday. Time was a taut string; it couldn’t be allowed to snap.

First-floor lobby. He swiped through the side door and stepped onto the street. The early autumn wind carried dust and exhaust fumes. He stood beneath the bus stop sign and pulled his phone from his backpack. The screen lit up with two unread messages. One from Academic Affairs: “Practical test submission received. Please download the score acknowledgment once the system opens.” The other from Old Zhao: “Data accepted. Balance settled tomorrow. Next job, I’ll come straight to you.”

Lin Chen stared at Old Zhao’s message. The balance. He ran the numbers: combined with the internship salary, his cash flow would barely turn positive. He replied: “Received. Provide format templates in advance for the next request.”

The bus pulled into the station. He dropped a coin, tapped his card, and walked to the back row to sit. The street scenes outside the window scrolled backward, like log entries being skipped. He took out his notebook, flipped to a fresh page, and wrote: 2010.10.15 Provincial Institute of Technology initial screening passed. Onboarding at provincial capital branch. Evaluation criteria: independent module. Risks: foot injury/cash flow/practical receipt. Next steps: vacate dorm, buy meds, confirm practical score.

The pen paused. He added a line: Don't pursue perfection. Pursue usability.

The bus reached his stop. He stood up, stumbled slightly as his left foot landed, and grabbed the seatback to steady himself. Across the platform was the campus hospital. He checked the time: 13:35. The afternoon registration window had just opened. He adjusted his breathing and walked up the steps. His reflection in the glass door was thin, but straight. The smell of disinfectant mixed with the damp mold of the corridor hit him as he entered. He walked to the triage desk and handed over his student ID.

“Sprained left ankle. Prescribe some topical medicine and bandages. I just need to be able to walk,” he said.

The nurse looked up at him, asked no questions, and began writing the prescription. Lin Chen leaned against the wall, pulled half a compressed biscuit from his pocket, and chewed it slowly. He knew tomorrow wouldn’t be any easier. But at least, he had secured the next ticket. And the destination of a ticket is never decided by others; it’s paved step by step under your own feet.
