76 Space Station Operating System
Backstage in the big data center, many hired expert judges were chatting.
Everyone was basically focused on one thing.
Li Chengqian scored full marks in the theory exam.
"Do you guys think Li Chengqian will also be the first to hand in his paper for this hands-on programming test?" Shi Chengsan, who had just graded Li Chengqian's theory test in the morning, joked.
"It's hard to say. Li Chengqian's theoretical foundation is especially good, and his programming ability is excellent. However, this question on this space station is very difficult. He has to translate the meaning of the questions into mathematical models before he can program." a judge guessed.
His point was very clear. He believed that Li Chengqian was strong in both theory and programming ability.
However, no matter how good he was in programming, there was a prerequisite. That was, the problem had to be converted into a mathematical model first.
"Ding-dong. You have received a new test paper for review…" At this moment, a notification sounded from the computer in front of Shi Chengsan.
"Quick take a look and see who has handed in the paper. Let's see if it's Li Chengqian." Someone jeered. Then, many people came over and stood behind Shi Chengsan.
Shi Chengsan opened the marking system and glanced at the name of the person who handed in the paper.
Li Chengqian's name was reflected in his eyes.
"It's indeed Li Chengqian!" Someone said in surprise.
In the marking system, the exam was divided into two parts: 30 marks for mathematical modeling and 70 marks for programming.
"Old Shi, take a look at his mathematical modeling first." In the midst of everyone's commotion, Li Chengqian's simple mathematical deduction process was displayed in front of everyone.
"Wow… Impressive!"
"He modeled the problem with just five formulas. Li Chengqian's team not only has a programming expert like Li Chengqian, but also a mathematics expert."
"Impressive… I saw that the standard answer was three A4 pages long. Li Chengqian's team's submission didn't even take half a page, and yet they managed to clearly explain all the issues." To be honest, if they hadn't seen the model answer in advance, they might not have understood Li Chengqian's submission.
"Full marks, full marks for mathematical modeling!" Shi Chengsan filled in 30 marks on the scoreboard and proceeded to submit it.
Then, he opened the Positional Control program written by Li Chengqian.
After downloading the codes, the neat codes were displayed in front of everyone. Whether it was indentation or annotation, it was like a textbook.
As the test progressed, everyone's faces were filled with utter shock.
Li Chengqian's software had completely exceeded everyone's expectations.
To make an inappropriate analogy, it was like Li Chengqian proving that 1+1 = 2, when the question only asked what 1+1 was. He went beyond answering a primary school level question to doing what a mathematician did.
This was not the standard of a high school student at all. This was in fact the standard of a computing PhD supervisor, or even higher.
"There are 1,350 lines of code, and the file size is 65Kb!"
"The software has a core module and five functional modules."
"The software has an operation core that provides a virtual hardware system. As long as the drivers of the relevant equipment are integrated into the software, this software can operate directly on the space station."
"Five functional modules, Flight Mode Control, Automatic Flight Altitude and Speed Control, Automatic Flight Safety Control, and a real-time display system that shows speed, altitude, fuel level, and other relevant information in real time."
"All the modules are functioning well, there are no bugs found!"
"It's not just a software!"
"This is an advanced space station operating system that just needs finetuning!"
"Li Chengqian's hands-on programming, full marks!" In the end, Shi Chengsan filled in 70 marks on the evaluation column without hesitation.
"I propose that the organizing committee of the competition inform the National Space Science Center about the Space Station Positional Control program that Li Chengqian developed." With some slight modifications, this could be used as an operating system for space shuttles and satellites.
"I propose that we immediately embargo Li Chengqian's software and source code. This source code is very advanced and critical. It must not be leaked. The organizing committee of the competition should immediately report this matter to the National Administration of State Secrets Protection, and have them handle this matter." In the past, the space station's operating system was specially customized, and the research and development cost was tens of millions.
Once Li Chengqian's source code was leaked, all it took was a simple modification for it to be usable as a general operating system of a space station.
This was an important technological breakthrough!
"I'll report it to the relevant authorities immediately." When Chen Lili, the person-in-charge of Jinshan Province, heard her subordinate's report, she became very solemn and quickly rushed to the National Administration of State Secrets Protection to report the matter.
…
In the square of the Big Data Center, Li Chengqian and the others were informed by the competition staff that they were not allowed to leave the competition hall. As such, they had no choice but to wait in the square. Li Chengqian began to explain to Ding Ling and Zhao Peng his thought process behind the solution, as well as the usage of the five formulas he had written.
"…this is the specific meaning of the five formulas. Actually, it's not as difficult as you think." Li Chengqian explained the effects of the five formulas to the two of them in detail.
Zhao Peng listened with a perplexed expression. She didn't understand at all.
Ding Ling seemed to be deep in thought. She took the five formulas written by Li Chengqian and started thinking again.
"Captain, why do you think they are not allowing us to leave the Big Data Center?" Zhao Peng glanced at the main door. The door was tightly locked. Two security guards guarded the door, not letting anyone in or out.
Zhao Peng had already walked around and realized that all the entrances and exits of the big data center were guarded. No one was allowed to enter or leave.
"I don't know either." Li Chengqian was also at a loss.
"Ding, ding, ding… The hands-on programming test for the Junior Informatics Programming Competition has ended. Please leave your seats and leave the competition hall." At this moment, the announcement for the end of the test sounded.
"Let's go, let's go. This time, they have no reason to stop us." After hearing the announcement, Zhao Peng immediately jumped and ran for the door.
At this moment, He Hongyun, Bi Jialiang, and Jian Qingli walked to the square.
He Hongyun had a smug expression on his face. Although the test question was very difficult, he still managed to solve it in the end. The mathematical model was to work out the change in the altitude of the space station. The speed of the space station had to change in order to change centripetal force, so as to achieve a balance between the centripetal force and the earth's gravitational force, which would in turn result in a stable flight of the space station.
After completing the mathematical model, he worked with Bi Jialiang to write the core Control code. Besides this, they also wrote a data display program that could show the altitude and speed of the space station.
"Bi Jialiang has decent hands-on programming skills. If he majors in programming in university, he can be recruited to be a programmer in my father's company after graduation." He Hongyun had never taken Bi Jialiang seriously in the past. What happened just now had changed his mind. He felt that Bi Jialiang was a talent that could be used.
"In this hands-on programming test, our team would score at least 90 marks!" He Hongyun had absolute confidence. Then, he saw Li Chengqian and the others standing in the square.
The smile on his face became even more smug.
"Li Chengqian's academic results are very good. It shouldn't be a problem to transform the question into a mathematical model." He Hongyun was not a fool. Although he was especially unhappy with Li Chengqian, he still had sound basic judgment.
"I heard from Bi Jialiang and Jian Qingli that Li Chengqian does not have any hands-on experience. He was only learning how to type a few days ago, and his typing speed was especially slow."
"During the competition, I have Bi Jialiang to help me. Only Jian Qingli was a burden."
"As for Li Chengqian's team, Zhao Peng and Ding Ling were both burdens. They couldn't help him at all."
"It would be considered good if Li Chengqian could compute the speed of the core and the speed conversion portion of the program. There was on chance he could do the rest."
"Therefore, I will definitely beat Li Chengqian in this hands-on programming test." He Hongyun couldn't help but laugh when he thought of this.
