"Take a look." Liang Xin heard Xiao Yuan ask, and hurriedly gave an order, and after the order, he saw Xiao Yuan standing up, so he asked, "Have you found the reason?" ”

"It's just a suspicion, and it needs to be verified." Xiao Yuan said.

"What exactly is the problem?" Liang Xin asked again, at this time, their conversation had attracted the attention of everyone in the computer room, including the technician sitting in front of the operating table.

"Have you heard of the Millennium Bug?" Xiao Yuan asked.

"The millennium bug, what is it, is it a virus?" Liang Xin frowned and asked, it was obvious that he was very unfamiliar with this term.

"Do you think the hotel's electrical system is caused by the Millennium bug?" The technician sitting at the console turned his head and asked, apparently he knew about the Millennium Worm.

"I just suspect that an old-fashioned AS/400 small machine like a hotel is the hardest hit area of the millennium bug, and you are also a professional, you should know, right?" Xiao Yuan said.

"I think this possibility is very small, if today is New Year's Day in 2000, it is very likely to be a millennium bug problem, but at the current time, it should not be a millennium bug." The technician said.

"What if someone deliberately tampered with the machine's time?" Xiao Yuan said.

"If it is changed, it should be reflected in the power system, but the time of the power system is normal." The technician said again.

"So I asked you to check if the machine time and the power system time are the same." Xiao Yuan said.

"Where do you get so much nonsense, let you check it, you will check, hurry up, delay for a minute and lose a minute." Liang Xin heard the technician arguing with Xiao Yuan, so he urged impatiently.

The technician saw that the boss was angry, so he naturally didn't dare to delay any longer, and clicked on the keyboard a few times, and the power system that originally covered the screen became a command line, and he entered another command in it, and in the crisp carriage return, a line of time was displayed behind the command line, jan-1st-2000, 00:55:45, 0:55, January 1, 2000.

"How is that possible?" When the technician saw this time, he immediately exclaimed, and the other technicians also reacted in the same way as him, and there was a lot of discussion in the computer room for a while.

"Change the time back now!" Liang Xin also saw this time, although he didn't know what the millennium worm was, but he also knew that the time had been tampered with, and immediately realized that there was a problem with the hotel's power system, which was probably the problem of this time, and his spirit suddenly lifted up, and he hurriedly commanded.

The technician looked at his watch, quickly adjusted the time to the correct value, and then without Liang Xin's instructions, he called out the power system and executed a restart command, and after more than ten seconds, the power system was successfully restarted.

Liang Xin turned around and walked out of the computer room, and found that it was bright outside, and the power had returned to normal, so he turned back to the computer room, looked at Xiao Yuan with a look of adoration, patted him on the shoulder, and laughed: "Xiao Yuan, you are amazing." ”

"The blind cat has met a dead mouse, you don't have to look at me like that." Xiao Yuan said that while seeing the system return to normal, he was relieved and happy.

"You are too modest, they have so many open-eyed cats looking for an hour and have not found a problem, you have been here for twenty minutes, and you have found the problem, but it is not a sentence that a blind cat can explain the problem, anyway, this time you have made a great contribution, how do you want me to thank you?" Liang Xin said that the problem of electricity was solved, the stone that was pressed on his heart fell to the ground, and he became easier to speak.

"It's all friends, it's just help, and it's a shame to say that the reward is out." Xiao Yuan waved his hand and said, and then didn't forget to remind Liang Xin, "Let me remind you, the power system of your hotel should also be upgraded, otherwise in 2000, the millennium bug will still attack." ”

"What exactly is a millennium bug, a virus?" Liang Xin then remembered that he didn't know what a millennium insect was, so he asked curiously.

"The millennium bug can also be said to be a virus, because once it occurs, the possible consequences are comparable to some malignant viruses, or even surpassed, but it can also be said that it is not a virus, because it is not something that people can program, it is a historical problem, and the early computer hardware is very limited, so when programmers at that time design software, they should consider how to save computer hardware and reduce memory occupation while considering the software function."

Xiao Yuan first briefly talked about the background of the appearance of the millennium insect, and when he saw that Liang Xin was listening, he continued:

"In such a context, in many early computer systems, the year in time is expressed in two digits, for example, our current year 1999 is expressed as 99 years in the computer, then, there is a problem, when January 1, 2000 comes, the computer time becomes January 1, 00, but many computer software will regard this 00 years as 1900 years, not 2000 years, so that the computer time is out of order, Many time-related programs will run incorrectly or even stop running, which is the Millennium Bug. ”

"So the hotel's power system server is too old, so the millennium bug is inevitable?" Liang Xin asked.

"Unfortunately, IBM's AS/400 second-generation minicomputer just meets the conditions for a millennium bug attack." Xiao Yuan said.

"Okay, I know, I'll report this to my dad when I get back, and when the time comes, all the old computers in the hotel will be replaced." Liang Xin said.

Xiao Yuan smiled, the purpose of the reminder was achieved, as for what Liang Xin did, it was not his concern.

"Xiao Yuan, you and Kunpeng, Xiao Jun, let's go down first, there are some things I have to deal with here." Liang Xin said to Xiao Yuan.

"Okay, there's nothing going on here for now, I'll go back to school first." Xiao Yuan said that it was almost ten o'clock in the evening at this time, and if he delayed any longer, he would lock the door when he went back to the dormitory at night.

"It's okay, I'm inviting you to dinner another day, I'm really sorry that something like this happened today, you don't have to worry too much about the police, I can help you block it, if necessary, I will also arrange for my own people to go over to you to go through the motions, and you will insist that it is legitimate defense in 1713 at that time." Liang Xin said that because there were still many things to deal with in the hotel, he was not in the mood to entertain Xiao Yuan again, so when he heard that Xiao Yuan was leaving, he agreed.

Xiao Yuan, Wang Kunpeng, Xiao Jun, Li Mingfan and Qiao Leping left Liang Xin, left the computer room on the twenty-second floor by themselves, returned to the VIP hall on the twentieth floor, called Duan Yanyue, and left first.

After returning to school, Xiao Yuan's life returned to normal, going to class every day, going to meet Xia Jiuying in his spare time, and going to his office in the entrepreneurship center in the evenings and weekends to do his work for the open source community.

Three days passed quickly, and the police never came to look for him, Liu Dong officially resigned from Xuanne Company at the request of Duan Yanyue and Xiao Yuan the day before, and returned to school to work full-time for the open source community.

This day is the weekend, the weather is a little cold, the air is extraordinarily humid, it looks like it is going to rain, Xiao Yuan sat in the office of the entrepreneurship center for a morning, and temporarily stopped his work at twelve o'clock, ready to go to Liu Dong and Duan Yanyue for lunch, the office phone rang, after he connected, it turned out to be Liang Xin calling, saying that he would invite him to dinner again.

ps: The second shift is delivered, and there is a third shift and a fourth shift later.
