Chapter 50 Minix System
The meeting with Ni Guangnan was on the morning of the Lantern Festival, and the place was very special, in the park, which was the place where the two national treasures practiced every morning.
is about the same as in the photo, in his fifties, thin, with a pair of gold-rimmed glasses, his eyes are condensed, and he has an elegant momentum.
This is Wang Anran's first impression of him, compared with Wang Anran's enthusiasm for Ni Guangnan, Ni Guangnan is much colder to Wang Anran.
"Listen to Lao Su, your company is developing an operating system, is this true?"
Wang Anran nodded and said, "So please ask Academician Ni to guide our work." ”
"Academician Ni?"
Ni Guangnan will be rated as an academician of the Chinese Academy of Engineering this year, and the internal news has long been spread in the academic circles, and it is estimated that Lao Ni also knows that Wang Anran sent a high hat, who would think, Ni Guangnan does not seem to be very interested.
"If there is no shadow, don't spread it nonsense, Xiao Wang, you are now in graduate school, you should finish your studies well, how did you think of doing an operating system?"
Wang Anran said with a smile: "Dean Ni, there is a kind of learning called learning from books, and there is another kind of learning called learning by doing, I think I should belong to the latter type!"
Ni Guangnan said: "Before you do it, you must always gnaw through the books, since you are now going to do an operating system, you should be very interested in the booklet written by John Lions!"
The corners of Wang Anran's mouth turned up, he didn't just study the booklet written by John Lions, and basically memorized it in order to understand the principles of the Unix operating system.
Speaking of John Lions, the Australian is also a cow x, he is a professor at the University of New South Wales, one day he is full of food and nothing to do, so he will have fun and have fun, professor, high IQ, different from ordinary people looking for fun, John Lions took the Unix source code and explained it one by one.
Who knew that after the joy, many universities would have an additional textbook, and the majority of computer science college students would have another course to learn.
In order to save college students who are serious about their studies, AT&T, a Unix development company, banned college students from studying Unix source code in college classrooms when it released the Unix version 7 version, but if you are interested in the operating system, you can still find it if you look for it carefully.
Wang Anran simply memorized a piece of the source code of a Unix batch file, which made Ni Guangnan also nod.
Su Lao has been watching from the sidelines, and when he saw this, he smiled at Ni Guangnan and said: "Guangnan, let's be deflated, you really haven't necessarily tested him in this kid, he, after the class, take the big computer, go to the foreign server, and find information to learn." ”
Ni Guangnan shook his head and said, "Understanding and doing are two different things. ”
Wang Anran said: "Professor Ni, if you can, I hope you will visit Huaxin Technology to investigate, the first version of our operating system has been completed, and it is now being debugged." ”
Ni Guangnan's face was a little unnatural, and he said, "Xiao Wang, you said that you have developed an operating system?"
Su Lao next to him was also shocked, originally thought that it would take a few years to develop, but he didn't expect that in a few months, the first version had already come out.
But so fast, can the quality be guaranteed? Won't it be a trick, a foreign system is autonomous? Both of them were a little skeptical.
Wang Anran was a little surprised by the two of them, and said with a smile: "Two professors, look at it, look at it, let's talk about it, okay!"
............
Ni Guangnan was suspicious, a young man, there was not much hair on his mouth, could he do things reliably? But when he arrived at Huaxin Technology, he was stunned at the first glance in the computer room.
A little out of shape walked to the screen, pointed to the software on it and said to Wang Anran: "This is the MINIX system?"
The employee who was operating the computer was a little disgusted, where did the old man come from, disturbing him to work, but seeing the boss next to him, serious, like a little daughter-in-law.
Knowing that this old man couldn't be provoked, he stood up and moved out of the way and introduced: "This professor, this is indeed the MINIX system. ”
Ni Guangnan turned his head to Wang Anran and said, "Where did you get this system from?"
Of course, it's on the Internet.,MINIX system file is not small.,It's been two months on a small computer in Qingda.,This is still a network tool that uses multi-point resumption.,Otherwise, it's estimated that it will take a few years to download.。
Speaking of the MINIX system, then we have to talk about another idle egg-sore professor, Tanenbaum, academician of the Royal Netherlands Academy of Sciences and Arts, IEEE and ACM fellow,
After AT&T banned college students from studying Unix in class, Tanenbaum thought about how many human tragedies these hormonal college students would have had if they hadn't studied textbooks.
In order to avoid such an outcome, Tanenbaum thought about it, and he was idle anyway, and he himself rewrote a completely new operating system according to the principles of the Unix kernel.
This system is very good!
Where is Ox X?
It doesn't use a single piece of Unix system code, but from a user's point of view, the system is fully Unix compatible, and internally it is completely different from Unix.
Perfectly circumvented Unix intellectual property.
Put it in class, like a medical student, dissecting a frog, putting the inner workings of the operating system in the spotlight and having an unobstructed view.
Even the students with the worst grades don't have much difficulty reading the code.
And that's not all.
There is also a better thing about this software, its code architecture adopts a more modular architecture, which is the development direction of the future operating system to enhance reliability.
When Wang Anran was preparing to make the operating system at the beginning, he planned to use the MINIX system as the company's electronic data, and the company's software engineers could learn the principles of the operating system in the computer room at any time.
There is no way, at this time, there are only a handful of software engineers with experience in operating system development, and many times, they just complete specific things.
The design of the architecture module is basically completed by Wang Anran, and Wang Anran is also deliberately training these people, hoping that through this Linux development, a group of imaginative system engineers can be cultivated.
Ni Guangnan, who couldn't wait to sit in the chair, tried to operate.
Ten minutes later, Ni Guangnan was a little unsatisfied, his eyes kept sweeping to the screen, and said to Wang Anran: "I saw this system when I was in Canada, and in foreign countries, this is regarded as a university course, but the country wants to introduce this set of electronic textbooks, and people are unwilling, and this blockade is blocked to academic research." ”
Ni Guangnan sighed, turned his head and continued to say to Wang Anran: "Xiao Wang, I want to discuss one thing with you, I need a copy of the MINIX system, what do you think?"
Of course, Wang Anran nodded and agreed, it is best for every university to have a set, the development of the IT industry needs the support of the general environment, and what is the general environment, in Wang Anran's view, is talent.
Talents are rare, Ni Guangnan is not so emotional, at this moment, he suddenly has some expectations......
"Anran, take me to see your operating system, ...... quickly"
