The Red Era, the Opening University Speech

Chapter 249 Linux is the best choice
Although the first electronic computer printer was invented in 53, subsequent laser printers, inkjet printers and color inkjet printers were not produced until the 70s.

If he takes it out now, it won't be out of place at all, and it can even be bundled with the Type 01 computer that is about to be sold.

Li Mu thought to himself: "Not only printers, but also computer peripherals include plotters, which are also very important things."

Let’s not talk about things like keyboards, mice, and cameras for now. It won’t be too late to do that after personal computers are developed.

But this plotter is really interesting.

Its main function is to automatically draw graphics according to people's requirements and output the computer's output information in the form of graphics. It can draw various icons and statistical charts, geodetic maps, architectural design drawings, circuit wiring diagrams, various mechanical drawings and computer-aided design drawings, etc.

Its application directions cover important fields such as engineering, design, education and scientific research, and it will definitely be snapped up by OM countries if it is brought out.

"A hot plate, a laser printer, and a plotter should be enough for now." Li Mu stopped writing. Three projects were already a lot.

The technical team is just being established and needs some time to get used to each other, and we cannot increase the intensity too much all at once.

The days are still long, take your time.

……

After doing all this, Li Mu stood up, stretched his body, and then prepared to go to bed.

At this moment, a message alert sounded in his mind.

Open the chat page.

Ask:
"Li, she gave me a gift, do you think I should give her one in return?"

"But returning it to her will not make her misunderstand even more?"

"But if you don't return it, this gift is quite expensive."

Li Mu could see Ask's dilemma from the lines.

It can be seen that this girl did cause him considerable trouble.

So much so that the original topic between the two of them had changed from games to women.

"Just curious, what did she give you?" Li Mu asked.

Ask: "It's a rare card from Yu-Gi-Oh - Blue-Eyes White Dragon. Picture jpg."

"Oh my god, what a rich woman! Why don't you just give in to her?" Li Mu couldn't help but exclaimed when he saw the card.

The pure gold Blue-Eyes White Dragon was once sold at a judicial auction for a high price of 8700 million yuan.

Although some netizens are just making fun of it, the actual price is not that high, but the value is about 30 yuan, which is about to yuan when converted into M dollars.

"It's so expensive, I didn't know it!" When Ask saw Li Mu's message, he searched for the price belatedly and was also shocked.

Although he likes Yu-Gi-Oh, he doesn't know much about the prices of these game cards.

If he knew it was so expensive, he definitely wouldn't have accepted it.

Li Mu thought for a moment and said, "Then why are you going back?"

To be honest, he was a little envious of Ask, the pure gold Blue-Eyes White Dragon, he had wanted to get one before but never succeeded.

"I just said I like it, so I changed my mind right away. That's not a good idea." Although Ask was tempted, he hesitated after hearing what Li Mu said.

He really liked this card, and he thought it was expensive only because he was surprised that a card could be sold at such an exaggerated price.

Li Mu saw through his thoughts and said, "Then you should return her a gift, and we won't owe each other anything."

"Okay, but what should I give you?" Ask hesitated for a long time and finally replied.

Seeing this, Li Mu suddenly became excited and spent an hour teaching Ask what to give so that the other party would "hate" him.

Stable, stable!
……

Day two.

After Li Mu got up and washed up, he did some exercise and then came to the Chinese Academy of Sciences with the plan he had written last night. He handed it to Guo Mo, who passed it on to Leader Qiu on his behalf.

The latter, as the general manager of a semiconductor group, naturally attracts a lot of attention, and he would not have any contact with the other party if he could avoid it.

After Guo Mo saw the three new products presented by Li Mu, he couldn't help but praise them: "Great, great! This printer and plotter can not only be exported to earn foreign exchange, but also play a great role in the development of many fields in our country!"

"This one is not as fast as the other, so OM probably doesn't need it. But it's just right. You can use it to consolidate your reputation as the king of invention."

"As long as you think it's feasible." After hearing others calling him the King of Inventions for so long, Li Mu gradually became less ashamed as he was at the beginning, and nodded with a smile.

Guo Mo carefully put away the plan and continued:
"By the way, the issue you raised earlier regarding the formulation of semiconductor industry standards has already been approved, and it has been decided to convene experts and professors for discussion."

"The meeting will be held tomorrow at the Great Hall of the People. You will continue to participate in it as 'Hetu'."

"There are many different voices about this meeting, so you have to be prepared."

"Don't worry, leader. I've been prepared for this." Li Mu nodded slightly with a firm tone.

There will definitely be different voices when it comes to setting standards, but this is an inevitable measure and he will insist on pushing it forward even if it offends people.

Hearing this, Guo Mo said with confidence: "It's good that you have confidence, but don't worry too much. Everyone is just making reasonable suggestions for the development of the group and the industry."

……

After saying goodbye to Guo Mo, Li Mu went to the Semiconductor Research Institute to continue his research.

After arriving at the institute, he first went to the Type 02 computer development group and looked at the progress, which was almost completed.

Wu Xi made a final summary report with him and said:

"The computing power of this Type 02 computer is expected to reach 1000 million times per second, with a peak of more than 1200 million times per second."

"There have been significant improvements in power consumption, heat dissipation, hardware life, and so on."

"The most important thing is that the cost has been reduced by half compared to the 01 computer, now around 12W. After mass production, it should be able to be reduced to 10W or even below."

After hearing his report, Li Mu smiled, patted Wu Xi's shoulder heavily, and said:

"Well done, now that the Type 02 computer has been developed, the speed of scientific research in all fields of our country will be able to reach a higher level in the future!"

"It's just some hard work, but the key is that you, Consultant Li, have always grasped the general direction, so we can concentrate on research with confidence." Wu Xi said with a smile.

Although Li Mu did not appear to be too involved in the development of the Type 02 computer, he actually kept a firm grip on the direction and ensured that they were on the right track.

Without this guarantee, they would have to try for a year or half a year just to make mistakes, and they don’t know how much resources would be wasted.

While the two were talking, Wu Youxiang and Wang Shoujue also rushed over after hearing the news. Looking at the assembled Type 02 computer, their faces were filled with excitement.

They both said in unison: "Congratulations, you have accomplished another great feat!"

"I'm just doing my part for the country's scientific development." Li Mu looked at Wu Xi, who had no intention of taking credit for the work, so he had to speak seriously.

Wu Youxiang smiled and said, "That's right. We are all doing our part to promote the scientific development of our country." "It's just that your contribution is much greater."

These words made Wang Shoujue and Wu Xi smile.

Li Mu could only wave his hands, not knowing whether to laugh or cry.

……

They chatted for a while, Wu Youxiang praised Li Mu in various ways, and then left quickly with the news.

He first came to the Chinese Academy of Sciences and reported to Guo Mo the news of the completion of the Type 02 computer.

Hearing that the computing speed reached 1000w times per second, and the peak reached 1200w times per second, especially when the cost could be reduced to 10w, Guo Mo, who had just parted with Li Mu, was so happy that he wanted to go over and hug this lucky guy and give him a big kiss.

Increasing computing power is important, but reducing costs is more important.

Is the 01 computer good? Of course it is good, compared with the original domestic computers, it is a hundred times better, but the cost is still too expensive.

So far, the number of Type 01 computers produced has not exceeded 1000, and research institutions across the country are using them in full.

If the cost can be reduced, then even if everyone doesn't have one, at least the situation won't be so tight.

Thinking of this, Guo Mo immediately called Leader Qiu.

After receiving the news, the latter immediately asked his secretary to convey the order, asking the factories below to be on standby. As soon as he got the design drawings, they would immediately start adjusting the production lines and start mass production.

……

On Li Mu's side, although the Type 02 computer was successful, he did not relax for too long.

He immediately pulled Wang Shoujue and Wu Xi aside and started talking about the development of the operating system.

With the increasing computing power of computers and advances in hardware and software, the operating system must also be upgraded.

It turned out that the level of computer development in Xia Country was relatively low, and the operating system was also relatively simple, with programs being input through assembly language and perforated paper.

The later Type 01 computer used an operating system that Li Mu developed by combining the CP/M and MS-DOS systems and was more suitable for the current level of computer development.

However, as computers are upgraded, the operating system is further optimized to meet hardware and software requirements.

This time, Li Mu's plan is to directly use Linux, an operating system that can meet the needs of multiple users, multiple tasks, multiple threads and multiple CPUs.

The key is that it inherits the network-centric design concept of Unix and is a multi-user network operating system with stable performance.

This is a good thing for his subsequent research plans on local area networks and the Internet.

Of course, in addition to Linux, there is also the famous Windows system.

It’s just that Windows requires more hardware resources than Linux, especially when running complex programs.

In the fields of servers, embedded systems, scientific computing, etc., Linux's application software support is also more powerful.

Taking all factors into consideration, Linux is the best choice.

Li Mu introduced:
"The basic idea of ​​this operating system is twofold: first, everything is a file; second, every file has a definite purpose."

"The first one is that everything in the system is reduced to a file, including commands, hardware and software devices, operating systems, processes, etc. For the operating system kernel, they are all regarded as files with their own characteristics or types."

"It is both an operating system and a development tool, and a large number of projects can be developed based on it..."

……

Linux is a relatively late computer operating system and many of its functions cannot be realized now.

However, this does not affect its research and development, let alone its use.

Develop the system first, and then when the Type 01 personal computer comes out, it can be installed, which will be much more convenient.

"Such a complex operating system is probably not a small project!" Wang Shoujue couldn't help but sigh after listening to what Li Mu said.

To be honest, the software design team already has a lot of research and development tasks to do.

Computer simulation platform, material calculation software, CAD, CAM, CAT, CAE, six software development projects keep the team busy every day.

Li Mu thought for a moment and said:
"Except for the computer simulation platform and material calculation software, other projects can be put aside for the time being, and we can focus on developing this operating system."

“If we can complete it, it will be of great help to the subsequent development of many of our software.”

"As for the manpower issue, you can contact Mr. Yan from the Institute of Computing Technology and ask them to send some people over to help."

The Semiconductor Research Institute will focus on technology, and the Semiconductor Group will focus on products. This is what Li Mu has in mind.

He will basically hand over computer-aided software such as CAD, CAM and CAT to the product department for development in the future.

I will only take over the problems that are too difficult and solve them myself.

"Okay, then I'll call Mr. Yan now, and we'll have a small meeting in the afternoon to talk in detail about this...this operating system." Wang Shoujue paused slightly in the middle.

After saying that, he couldn't help but say helplessly: "Why don't you give this operating system a name? You can't just keep calling it this system, right?"

"Okay, let's keep it simple and call it Type 01 Operating System." Li Mu said without thinking.

Upon hearing this name, Wang Shoujue and Wu Xi both held their foreheads in their hands, unable to complain - it was too simple.

……

In the afternoon, after Yan Peilin came over and had a meeting with Li Mu and others, and after learning about the Type 01 operating system, he immediately decided to participate in the research.

That night, he brought people over to discuss the framework establishment of the operating system all night.

As the person who proposed the idea, Li Mu certainly couldn't leave and stayed with him until late at night.

It was Guo Mo who heard about what happened here and called them at 12 o'clock. Only then did they give up reluctantly.

……

The next day, Li Mu yawned and came to the Great Hall of the People.

After the inspection, he stayed in the broadcasting room, preparing for the upcoming semiconductor industry standards conference.

He had already sorted out the content, but to be on the safe side, he still went over it in his mind.

While he was on high alert, representatives from research institutes and factories from all over the country entered the Great Hall of the People one after another.

As soon as they came in, they started asking people which expert had nothing to do and suddenly wanted to develop semiconductor industry standards.

A director of a research institute in Liangguang said: "Every place has a different level of development. It's nonsense to set industry standards and force them to be the same."

"Yes, if the requirements are the same, the cost will definitely increase significantly. It's not like we can't sell them now, so there's no need to set any industry standards." A representative from a Shandong factory echoed.
