Get up together in the morning, Wu Lei was washing in the bathroom. His toothbrush was still horizontal in his mouth, and the white foam was still on the corner of his mouth. He seemed to suddenly think of something and shouted for no reason: "bug, bug, damn bug, I found the reason why the green light was not on!" The splashed foam instantly turned the dressing mirror in front of him into a white-spotted face.
wife Li Lin was dressing her daughter on the bed. When she heard his shout, she said lightly: "Looking at you, you are so shocked that the code is so infatuated!" She looked very calm. This situation was common to her. She worked endlessly overtime, her dream of programming, and her obsession with any smart product. Alas, his programmer husband always did this.
Wu Lei finished his breakfast in a hurry and drove his Mazda to the hospital to see a friend, and arrived at a busy intersection. He was about to turn left, but there was a long line in this lane, which had been twenty minutes and could not drive through. The impatient drivers kept honking the horns, and the whistles sounded one after another. Looking at the left turn arrow that has not turned green, his professional sensitivity made his brain turn quickly. He kept muttering: "The person who wrote the traffic light control software must have a short circuit. The time scheduler is designed too unreasonable and I don't know what the optimal planning is! There are few vehicles on the straight road, and there is a large comprehensive hospital in the direction of the left. This does not evaluate the size of traffic flow. It's simply a fool!"
stopped and stopped all the way, and finally arrived at this hospital. Wu Lei parked the car to the underground garage of the inpatient department. After locking it, he came to the elevator entrance that directly leads to the inpatient building. There are many people waiting for the elevator, and it is no wonder that this is the peak time for visiting patients in the morning. The doors of the four elevators open and close, and people go in and out, but they are always in order. The sensitivity of the profession aroused his curiosity. He thought that the coordinated control of these four elevators was done well, and personnel diverting was carried out according to the floor, which not only facilitated the transfer between the elevators, but also did not allow crowds of people, and the operation efficiency was high. It was really good. He seemed to see the programmer behind the elevator, and he couldn't help but lit his head and made a squeak.
Wu Lei is a software engineer. He has been engaged in the development of embedded software for electronic products. He deals with real-time operating systems such as VxWorks and Linux day and night. c language is his old acquaintance and he has almost never used it for a day.
After reading his friend, he hurried back to the unit. Before he could wipe the sweat from his head, he didn't bother to drink a sip of water, so he plunged into the laboratory and sat in front of his computer. He couldn't wait to turn on his computer, skillfully entered the password, and called out the program he had been debugging for a while. Lines of code moved up and down quickly under the sliding of the mouse, red and green, dazzling.
soon, the mouse stopped at a branch of the condition. His eyes stared at the screen and quickly found the bug that suddenly occurred to him when he was washing up in the morning. His fingers were flying quickly on the keyboard. The crisp sound rang rhythmically. A string of letters and numbers mixed with various symbols quickly appeared on the screen, arranged obediently into program lines with orderly entry and exit.
did not modify many codes. After he entered it, he began to compile and link it quickly. After passing it successfully, he quickly downloaded the program to his product. He was looking forward to it relaxedly. This problem that had troubled him for more than a week might be completely solved today, so that the annoying boss no longer had to follow his butt and urged for progress.
He unplugged the flat download cable and happily connected the product's power supply. As soon as the switch was closed, hello, the green light that should have been light but never lighted finally flashed. The green light shone on his face, as if giving him hope to complete the task. He danced and was very happy.
He sat on the computer chair with satisfaction, turned around hard, then slowly lit a cigarette, sandwiched it between his fingers, slowly moved to his mouth, took a deep breath, and the smoke rings he spit out floated away. He couldn't help but recall the sleepless nights he stayed here working overtime, and his heart was surging.
product is still powered on and is running silently. Wu Lei thought about using more time copying machines to see how reliable it is.
Suddenly, he found that something strange happened to the product. The problem of the green light not being on was indeed solved, but a new problem appeared. It turned out that a normal-run program seemed to have not been run. It was obvious that it entered a dead loop again, and a new problem appeared again.
It seems that he is going to worry about this vicious cycle again, and his life has entered a new vicious cycle again.
