Fault Tolerance

Senior brother Gu Heng had been kind to him for a whole year. Helping him adjust code, revise papers, and bring instant noodles late at night, everything was done with sincerity. Then he plagiarized his core paper and accused him of fraud. Shen Yan didn't understand. How can a person treat you sincerely and steal your things at the same time? Later he understood. Some people can exist in both states at the same time. He was admitted to a junior college with a score of 391 in the college entrance examination. He was idle for a whole year until a girl named Fang Yun woke up with a sentence in the memo - "Anyone who knows where he is should not wait." He sprinted for 25 days from junior college to bachelor's degree, passed the postgraduate entrance examination, and took the Ph. D. Examination, and finally entered the country's only confidential laboratory for basic fault-tolerant systems. The fault-tolerant system he studies is a national-level technical defense line that allows critical infrastructure to automatically recover after being attacked. But his comrade Fang Yun is standing on another, more dangerous line of defense. Fang Yun died. She left a line on the last troubleshooting report: "The system is stable. Don't let it down." From Zhengzhou to Beijing, when a girl named Lin Jianwei put him his first cup of sugar-free coffee in the library, it took him five years to learn to accept a person's company, protection and side by side from a "hollow man" who relied on the deduction system to keep his distance from others. Lin Jianwei said: "You don't need to do any verification on me. I am your benchmark." This is a story about fault tolerance. Systems fail, and so do people. But some people never shift in your coordinate system.
