"Joint Recruitment Announcement of Artificial Intelligence Lab and Xuanne Open Source Community."

One day in mid-October, the School of Computer Science, the School of Mathematics, the School of Physical Engineering, and several other colleges of science and technology that have a certain relationship with computer science and technology suddenly posted such a recruitment announcement, which quickly attracted a lot of attention.

It is not uncommon for the laboratories of the school or a teacher to openly recruit people to work among undergraduates, but the students who have worked with the teachers at the undergraduate level in the university, or have helped in the laboratories, know that although some teachers or laboratories will give them some compensation, but this remuneration is often very meager, at most it is a hard fee, and some of them are not even enough for living expenses, and this remuneration will change according to the teacher's mind, which is very unfixed, and even some projects with little funds. Or the teacher picks the door a little, and these hard money is not necessarily given, the reason is of course very high-sounding - the teacher let you do the project, gave you the opportunity to exercise, and trained you hard, isn't this enough? -- And so on.

Most of the students also regard this phenomenon as the norm, are accustomed to it, and are even proud to be able to help in a certain project team, after all, teachers will definitely not choose mediocre talents.

This artificial intelligence laboratory is open to recruitment, and the usual laboratory, or teacher recruitment is a little different, because it is clearly stated in the announcement that if you are selected, there will be a reward, which is enough to attract the attention of many people, not to mention that the artificial intelligence laboratory is still a national key laboratory, even if you are not paid, it is a very honorable thing for undergraduates to be able to enter this laboratory to do something.

The recruitment was arranged by Duan Yanyue, Xiao Yuan didn't spend too much energy on it, he had more important things to do, that is, to design the overall architecture of several software projects, and then repeatedly discuss with his mother and a few professors invited by his mother, and then repeatedly adjust the software architecture.

Originally, there was no discussion with his mother and other university professors, but when he came up with the first draft of the software architecture and discussed it with his mother, his mother gave him a lot of very good advice, which was a surprise for him, and at the same time prompted him to change his mind temporarily.

In his original impression, the professors of the school represented by his mother may be stronger than him academically, but there is still no way to compare with himself in the actual project operation, but after several exchanges, he found that his original idea was a little deviated, in Jiangzhou University, a national key institution, people who can become professors, are not simple, academic not to mention for the time being, the actual project experience is also very rich, after reading Xiao Yuan's design plan, they can put forward some suggestions that convince Xiao Yuan according to their own understanding.

Therefore, he used a more open mind, took the initiative to take out the design architecture that he changed every time, discussed with his mother and a few professors that his mother helped him find, and then modified the technical architecture, changed the draft several times, and finally determined the plan, which was very different from the first version he originally came out.

And take a few professors who were invited by Yang Jingchen to help, after a few contacts with Xiao Yuan, the impression of Xiao Yuan has also undergone earth-shaking changes, in a small talk after the discussion of technical solutions, Peng Dacheng, the dean of the School of Computer Science, jokingly talked about this matter.

"Originally, we all looked at Professor Yang's face and came to help, but I really didn't expect that your computer professional foundation is so solid, especially the actual implementation experience of the project, which makes me feel deeply ashamed, if it weren't for the face-to-face with you, I would have doubted that I was communicating with an old engineer with many years of experience in the implementation of large-scale projects, which is really terrifying."

"Yes, I didn't feel sorry for Xiao Yuan didn't apply for our computer college, but now I know that if he applies for the computer college, it is really a pity, with the computer knowledge and technology he now masters, and then come to the computer school for four years of undergraduate, there are some suspicions of leftovers, it is really a good choice to go to the mathematics department, but, Xiao Yuan, if you graduate from the bachelor's degree, if you want to take the graduate exam, you must come to the computer college, with your current technology, plus four years of mathematical foundation in the mathematics department, In the future, we will definitely surpass our old men. Another professor, Lu Pingtao, said with deep sympathy.

For Peng Dacheng and Lu Pingtao's praise, Yang Jingchen was smiling, and although Xiao Yuan also felt very useful in his heart, he was not carried away and complacent.

When Xiao Yuan completed several software architecture designs for the open source forum with the assistance of his mother and several other professors, the preliminary test results of the recruitment of the Xuanne community and the artificial intelligence laboratory came out, and Duan Yanyue handed over the test papers of the fifty selected candidates to Xiao Yuan for him to see.

The first test paper is Xiao Yuan's paper, which examines some very basic knowledge, and the sophomore majoring in computer science is enough to make it easily, but although these test questions are simple, there are many traps buried by Xiao Yuan, so it is easy to pass, but it is not easy to get a high score.

Most of the 50 students who finally passed the preliminary examination hovered around 70 points, and only a few were able to break through 80 points, and only one person scored more than 90 points, and this person's 100 points on the paper actually scored 95 points.

So he pulled out the ninety-five point test paper, looked at the name on one end of the test paper, but was a little surprised, because this test paper turned out to be Cheng Wei's, flipped through Cheng Wei's test paper, and found that he wrote the fault-tolerant processing subprogram in the last programming question incompletely, and was deducted five points, if it were not for this reason, his score might have been full score.

At the same time, Xiao Yuan also found that Cheng Wei had a very good habit, even if it was the C program written on the test paper, he was meticulous in the indentation and blank lines he should have, and the annotations in the program were also complicated and simplified, just right.

"It's just that this guy's thinking is still a little too rigid." Xiao Yuan also found some of his deficiencies from the program written by Cheng Wei, and also took the programming questions as an example, what Cheng Wei wrote were very standard algorithms in textbooks, so the program was slightly lengthy, and Xiao Yuan's questions were actually some very ingenious algorithms, which can not only improve the efficiency of the algorithm, but also greatly reduce the amount of code, but Cheng Wei did not use them, perhaps he didn't think of those algorithms at all.

Xiao Yuan put Cheng Wei's test paper again, and looked at the test papers of some other students again, for these students, although the score is an important reference factor, but he chooses people, but he doesn't want to rely entirely on the score, the traps he set are actually to examine some habits of the students participating in the selection, such as the comments of the program, and for example, when writing the program again, whether he will take into account the fault tolerance and exception of the program he writes, whether he will write fault tolerance and exception handling code for some accidents that may occur, etc.

According to these, when Xiao Yuan looked at the test papers, he quickly eliminated some students who had good grades but had extremely bad habits, and finally left thirty-one students, whether these students would be selected or not, and he still needed to conduct further interviews, and he had to conduct this interview himself.

The time of the interview is scheduled in the afternoon of the second day after the preliminary examination results, the location is the conference room of the artificial intelligence laboratory, as the interviewer to participate in the interview, in addition to Xiao Yuan, the general person in charge of the project, there is also Yang Jingchen and another professor of the artificial intelligence laboratory, this professor is still Xiao Yuan's old acquaintance - Wang Bofang, he has no project in his hand during this time, so his mother arranged for him to participate in the future project team as a representative of the laboratory, as a technical consultant, Duan Yanyue in this interview, The role he plays is that of a clerk.

The interview officially began at half past two in the afternoon, and the first person to come in was a thin little girl named Li Mingming, who wore a pair of thick glasses.

"Let me ask you a question, how much do you know about open source software?" After the two sides greeted each other, Xiao Yuan asked the first question.
