Yan Yuanchao walked onto the stage in a suit and tie. He first glanced at the audience, then looked back at the huge screen projection in front of the conference hall.

The next moment, the lights in the conference hall gradually dimmed, and the projection screen slowly became brighter. A cute giant panda appeared in the center of the screen. At the bottom was a line of Song-style characters "Yuanwang Technology Developer Conference 1990".

Three-year-old children in later generations knew that giant pandas were national treasures, but in the 1980s and 1990s, the concept of "giant pandas = national treasures" was not yet deeply rooted in the hearts of the people, because it was not until 1988 that giant pandas were listed as national first-class protected animals. This year's Asian Games also used giant pandas as mascots. With this east wind, giant pandas were widely known to the people of the whole country.

Just as everyone was looking at the giant panda on the screen curiously, the screen suddenly turned black, and the background of the screen turned dark green. With a crisp sound of water drops, the giant panda appeared again just now, but this giant panda was just rougher than the one just now, and seemed to be composed of black and white squares.

Someone in the audience responded quickly and said in an uncertain tone: "Is this the boot screen of the operating system? Panda operating system?"

After he reminded him, the people around him suddenly realized and nodded.

"The host of Yuanwang Technology came up without saying a word, and did it directly, which was interesting!"

"I'm also here to host! The author of dos! You rustic bun!"

"Ah? He is Yan Yuanchao? Damn..."

"Look, the graphics operating system, damn it, it's much more beautiful than Windows 3.0!" No need to ask, this is definitely a good-looking control.

The performance control next to him sneered at this: "It's useless to look good, but it's not just a golden jade but a slim inside."

"I think the operation is quite smooth. Oh, is it dazzled? The window can actually close!"

"Yes, I didn't notice it if you didn't say it."

...

After the demonstration of the basic operations and gave everyone a preliminary impression of the new operating system, Yan Yuanchao cleared his throat and said, "What you just saw is the protagonist of today, the Panda operating system created by Yuanwang Technology. panda      os is a native Chinese operating system with a kernel of panda1.0, based on the bsd kernel of Unix, and follows the bsd license agreement..."

"Haha, I use the BSD kernel and a shell operating system. I just said, how could Chinese people write a new operating system? This trip was a waste of time, and I wasted my time and got away."

"You're leaving, why are you still sitting here?"

"You care about me! Humph, I want to see how Yuanwang Technology deceives people."

"I'm too lazy to pay attention to you!"

"I know, some people will definitely say that putting a layer of skin on foreign things can be considered our own operating system?" Yan Yuanchao said with a smile, "I think Dean Zhou said something very well just now. In terms of innovation, we must grasp, absorb, digest, use new things for my own use, and finally take a path of our own.

Although panda1.0 uses the BSD kernel, in the Panda kernel, bSD is only responsible for the underlying logic of the file system and only occupies a small part of the code. On this basis, we rewritten the process, memory, devices and network systems, and added an i/o      kit driver framework.”

While Yan Yuanchao was speaking, a panda kernel composition diagram appeared on the large screen. The figure shows the amount of code of each kernel subsystem, and the code derived from BSD accounts for less than 5% of the total code.

"I know, there may be people who are skeptical about the data on this picture. It doesn't matter, we speak with facts. A complete panda software is mostly based on panda    api. Whether it is binary-level abi or source-level api, it has nothing to do with bsd.”

panda1.0 kernel, panda compiler, panda software package manager, panda software development toolkit... As the slideshows on the big screen switched, the audience was talking louder and more and more awesome.

When I was presenting the word processing software wordeditor, the amazement reached its climax.

"Damn, what did I see? What I see is what I get!"

"It feels much more convenient than WPS and Microsoft's word."

"Damn, I'm really here today! There are constant surprises and climaxes!"

"When will this system be sold? You have to buy one!"

"I have internal news, saying that it will be the end of next year at the earliest."

"At the end of next year? No, this system is in the software, isn't this good? Why do you have to delay that long?"

"Don't worry, Developer Conference Developer Conference. After the meeting, we will definitely have a copy, otherwise what will we do?"

"Yes!"

Yan Yuanchao talked for more than an hour in one breath and finally introduced the operating system. At this time, he was already dry, but there was still hardware content. So he quickly picked up a bottle of Linglongquan and took a sip to moisten his throat, then nodded to the operator beside him, indicating that he could continue to play the slides.

"While we are developing the panda operating system, we are also designing computer chips. In the end, these two R&D lines intersected and gave birth to this guy, Yuanwang personal computer."

Everyone was stunned when they looked at the computer pictures on the big screen. Is Yuanwang Technology not a software company? Why do they still make computer hardware?

But this doesn’t matter. What’s important is that Yuanwang’s computer looks so beautiful!

In this era, almost all PCs were milky white or beige plastic shells. At this time, a silver or black metal shell suddenly appeared. A personal computer with the host and the monitor separated from the monitor could really surprise people. It turned out that computers could be built like this!

"Yuanwang personal computer uses Loongson CPU. Loongson CPU is based on the mips architecture. Based on the original instruction set and architecture of Mips, we have expanded it and added multi-threading and dsp modules. Compared with the CPUs of its competitors, Loongson CPU is better in terms of power consumption and performance..."

Computer hardware is different from software because it is more abstract. When introducing the operating system, you can at least demonstrate it on the big screen. However, when introducing the CPU, you can only talk about parameters and test data dryly, so Fu Song yawned when he heard it.

Looking at the time, it was almost twelve o'clock, and Lao Yan had been talking for more than two hours, and wasn't he too tired?

In his opinion, it is enough to just pass the hardware part by simply passing it. Those who understand it will naturally understand it. For example, those who don’t understand it, even if you talk about it forever, you still don’t understand it.

Suddenly, Fu Song remembered something and quickly reached out and patted the person on the shoulder in front of the right.

The little eyes were just hearing this, but unexpectedly, Fu Song was disturbed and turned around dissatisfied, "What are you doing?"

Yoho, I’m young and have a pretty temper. Well, when I swore you over, I’ll see how I’ll wear you with my shoes!

"Young man, I see that you have a brilliant bones and will surely achieve great things in the future..."

"Neuropathy!"

Fu Song: “….”

Seeing that he was defeated, Xu Lin had a dark face as if it was as bottom of a pot, and she covered her mouth and laughed so hard that she fell.

Fu Song glared at her fiercely and said angrily: "Smile! Your man is being taken by someone, you still have the face to smile! Smile again, wait for me and see how I deal with you!"
