I was reborn and stayed in school to lie down. I really don’t want to roll anymore!

"Hey, fine."

"Wait a minute, I'll be there right away."

In the afternoon, Brother Xu, who had just been in the office for a short while, was about to leave when a phone call came in.

"Xiao Jiang, can you come with me? The guy at the book borrowing window said the system is stuck again."

"This was the case last time. We even hired someone from outside to fix it, but it seemed to be of no use at all."

Jiang Hao had just finished his private work in the morning and had nothing to do for the moment, so he got up and followed Brother Xu.

"Brother Xu, how much did it cost the last time our school hired someone to repair it?"

"Three thousand! Every time I ask someone from outside to come, I feel that this money is easy to make."

In front of him, Xu Boping shook his head and sighed.

"This is actually quite a small amount. It's not cheap to come here anyway."

This price is definitely not low in 11.

However, facing the pile of shitty codes in the school, Jiang Hao even felt that it was not enough.

It is not difficult to make some changes, but finding the problems is the most difficult.

The book borrowing and returning window is on the first floor. There are four windows in total, and only one teacher is on duty today.

Looking at the library's borrowing window again, Jiang Hao couldn't help but sigh inwardly.

It’s still good these days, there are teachers at the window to help with borrowing records.

In a few years, all book borrowing and returning will be done by scanning machines, and these window positions will gradually be eliminated.

Since it is summer vacation, there are quite a few students coming to the library, but most of them are juniors and seniors on campus preparing for civil service exams and postgraduate entrance exams.

There is also a group of people from outside the school who are also preparing for civil service examinations and postgraduate examinations, so there are very few people borrowing books during the day, and there is only one teacher on duty at the window.

Their Songshiyuan University is open to the public, so the library's reading room or study room is almost full every day.

In front of the window was a female student wearing a short skirt holding two books and a student card, and on the other side of the window was a middle-aged woman in her late 40s.

"Teacher Xu, you are finally here. It's the same old problem again."

"After I scanned the book and returned it, it reminded me that the error was stuck here."

"Luckily this student wasn't in a hurry, so I didn't shut down the system and restarted it. I thought I'd let you guys come over and take a look."

The middle-aged woman looked at the system that was reporting an error and didn't work with a look of helplessness on her face, while apologizing to the female classmate opposite her.

"Student, I'm sorry. This problem keeps coming up. I'll ask our technical teacher to take a look. Don't worry, I'll help you borrow the book in a little while."

"Teacher, I'm not in a hurry, you guys take your time."

The female classmate was very understanding and nodded to the three of them, then continued to look down at her phone, probably replying to messages.

"Sister Yang, don't worry, this is Mr. Jiang, who is a great software technician and has just arrived in our office."

"Don't worry, he will definitely be able to solve this problem for you."

Regarding Mr. Xu's boast, Sister Yang also focused her attention on him.

Instead of doubting him because of his age, I trusted him even more.

"Teacher Jiang, please take a look at the problem."

As he spoke, he gave up his seat to him and whispered to Teacher Xu.

"Is this Mr. Jiang, the new teacher in your department? Finally, a young person has arrived. This computer system is something that young people like them can handle!"

The sound of Teacher Jiang's voice reached Jiang Hao's ears, making the experience quite novel.

Before his rebirth, the name he was most often called was Jiang Gong. The title of teacher was relatively rare, and Jiang Hao himself felt quite comfortable hearing it anyway.

"You previously hired people from outside companies to repair it. One time, someone came who was older than me. At the time, I felt that he didn't understand it."

"Sure enough, after fiddling with it for a long time, it was a young man who was with him who finally solved the problem."

From the complaints of Sister Yang and Brother Xu, we can also hear that she highly respects young people like Jiang Hao in terms of computers.

I guess it's only in this area that people don't doubt young people, but are full of prejudice against older people.

"Yes, he is a student who stayed on from the School of Information Engineering in our school. In his class, Mr. Jiang's skills were top-notch."

"Really!"

I don't know where Brother Xu got this information, or if he made it up just to help him brag, but what he said really can't be considered wrong.

And after he said this, the female student who was borrowing and returning books at the window looked up and began to look at Jiang Hao carefully.

Jiang Hao noticed it very quickly, and he might be very interested in being able to stay in school.

However, when he looked up and glanced at the female classmate in front of him, the girl quickly lowered her head and pretended to look at her mobile phone.

"I need to go back and look at the code. I can't find the problem just by looking at the page."

I don’t know who wrote this earliest version, and there is not even any specific information about the error.

It’s just a simple pop-up box with a line of text on it.

"System error, please contact the administrator!"

Good man, when he was writing code for the test system, he would be lazy and write it like this, because he knew where the error would be reported anyway.

This is a project I took over from someone else. There is such a common error. Considering the pile of shitty code, it will probably take a lot of work to find the error.

Jiang Hao was already complaining in his heart, at least write an error code number.

"Sister Yang, please restart the system or the computer first to deal with this student."

At the same time, he took out his mobile phone and took a picture of the title of the book and its number in the library.

"Okay! Teacher Jiang, let's leave contact information."

"Next time I have this kind of system problem, I will contact you directly, so that Teacher Xu won't have to call you again."

After hearing this, Jiang Hao finally realized that the flattery just now might be for this reason.

Thinking of this, Jiang Hao shook his head. It was his responsibility and there was nothing much to say.

After quickly adding Sister Yang’s WeChat, I went back to the office and started looking for the problem.

As for Xu Boping, he had already said hello to him and slipped away.

I don't know what Brother Xu does every afternoon, but it's none of his business. He guesses that he will go out for a walk every day when he has nothing to do in the future.

I sat down in the office again and started debugging the backup system.

Sure enough, an error occurred when I entered the book number when returning it.

Jiang Hao's frown disappeared immediately, as long as the problem could be reproduced.

The most troublesome thing about programs like these is that problems often occur on the spot, but when you go back to look for the problem again, you find that the problem has inexplicably disappeared.

Even many program problems can be solved by restarting the computer. It's very mysterious.

After a simple check, Jiang Hao discovered that the problem actually lay in the database itself.

Because the book numbers exceeded the number of digits that could be stored in this table field, Jiang Hao touched his forehead when he saw this problem.

I am really speechless. Is this kind of low-level problem the culprit for the system crashes in the past?

Trying to store 100 into 10? It would be strange if this didn't give an error.

Looking at the long list of codes regarding this issue on the library system, Jiang Hao seemed to suddenly understand something.

"Brother Zhang, can't the engineers who come to our school to solve system problems directly operate the database?"

"That's right. The database can only be operated by people in our school."

"This is a matter of principle. We cannot even take over the company that outsources the interface to access the database."

Okay, after hearing this, Jiang Hao completely understood.

The real reason for this shitty system code was found.

It’s not that the outside companies are of low quality or that they always cheat them out of their money, it’s that the school’s own regulations have problems.

There was a problem with the system. The underlying database could not be accessed by outsiders due to its nature and regulations.

We can only let outsiders modify the surface problems. No wonder this pile of shit is getting higher and higher.

In fact, it is just a matter of changing to a bigger cup when the water is full, but people are forced to find a solution from the speed, method, direction of pouring water and so on.

How is this possible? I guess these problems have been caused by the new books that arrived at the library since a certain year.

But this is a good deal for him, if there were no such regulations or such situations.

The library probably doesn't need to hire another one of him, and Principal Lin won't consider adding another place for him to stay in school.
