119: Chapter 119 again?

The name echoed through the conference room.

On both sides of the long table, several chief engineers from mobile terminal manufacturers exchanged glances.

The dragon is the totem of the Xia Kingdom.

Using Hidden Dragon as the name, combined with Lin Yuan as the developer... the meaning behind this was self-evident.

Of course, a name is ultimately just a code.

No matter how big the hype or how deep the sentiment, when it comes down to reality, it all depends on the actual quality of the system.

Lin Yuan took in the fleeting thoughts of everyone present.

He folded his hands, his fingers resting casually on the back of his hands.

"I can guess about seventy or eighty percent of what you are all calculating in your minds."

Lin Yuan leaned back slightly, his spine resting against the chair.

"As I mentioned earlier, most of the so-called domestic systems currently being developed in the country are based on secondary development of open-source monolithic kernels, just putting on a new shell to sell it."

"I don't like doing that kind of thing."

"Since we are going to build a foundational system that completely belongs to us, the people of the Xia Kingdom, in order to avoid criticism and to truly adapt to the future era of communication and intelligence..."

Lin Yuan paused slightly, his tone suddenly deepening.

"Hidden Dragon does not use any existing monolithic kernel architecture."

"Its foundation is the Spacetime Synchronous Microkernel, which I researched independently."

A microkernel?

As soon as these three words were spoken, a low uproar suddenly erupted on both sides of the long table.

A terminal software director sitting in the front row couldn't hold back; he leaned forward and spoke up boldly.

"Chief Engineer Lin, are you saying... a microkernel?"

The software director pushed up the glasses on the bridge of his nose, half of his body leaning on the table edge.

"The architectural logic of a microkernel is indeed advanced; this is a fact recognized by the international academic community."

"When we were conducting internal pre-research, we also tried to move in the direction of a microkernel."

He paused for a beat, his Adam's apple bobbing violently.

"But a microkernel moves most system services to user space, which leads to an outrageously high frequency of inter-process communication."

"The direct consequence of this high-frequency data interaction is extremely low efficiency."

"Moreover, the ecosystem for microkernels is practically a desert, and the difficulty of development and maintenance is unimaginably high."

"Plus, there are the adaptation problems between different hardware platforms..."

He cut himself off abruptly, staring straight at Lin Yuan on the podium.

"Chief Engineer Lin, you chose a microkernel, so these dead ends that are considered industry chasms, could it be..."

"You've solved them all?"

The conference room fell silent.

Everyone was waiting.

Lin Yuan didn't rush to speak.

His fingers tapped unconsciously on the table, and the corners of his mouth slowly curled into an arc.

"The problems you mentioned—low IPC efficiency, lack of ecosystem, difficulty in adaptation..."

Lin Yuan tilted his head, looking at the software director.

"These are indeed old complaints that have plagued the microkernel industry for many years."

"But have you ever thought about one question?"

The software director was stunned for a moment.

"What question?"

"Are these problems inherent flaws in the microkernel itself, or is it just that those who worked on microkernels before lacked the technical skill?"

This question left the software director speechless on the spot.

Lin Yuan didn't wait for his answer; he tapped his fingers on the table and continued.

"The reason no one has succeeded with a microkernel is not because the path is unworkable, but because technical means were insufficient; no one found the right way to approach it."

"Since I chose a microkernel, it naturally means that these problems have all been solved by me."

He spread his hands, his posture relaxed to the point of being casual.

"And not only solved, but the Hidden Dragon System's microkernel architecture completely crushes monolithic kernels across several core dimensions."

Completely crushes?

On both sides of the long table, the veterans who had spent their whole lives in software engineering widened their eyes, waiting to hear more.

Lin Yuan raised his palm and made a vague gesture in the air.

"For example, regarding the IPC efficiency issue that everyone is most worried about, Hidden Dragon uses a lock-free synchronization mechanism combined with spacetime slicing scheduling."

"The overhead of inter-process communication has been reduced to a negligible level. Multi-core computing power under this architecture approaches linear scaling, avoiding the situation in traditional microkernels where adding more cores just leads to more waste."

The software director's mouth opened slightly, closed, and then opened again.

Linear scaling?

Anyone who has done multi-core optimization knows what these four words mean.

In traditional monolithic kernel systems, when the number of cores doubles, the actual computing power increase often doesn't even touch sixty percent, with the rest wasted on lock contention and scheduling overhead.

But this system that Lin Yuan was talking about...

"Let's talk about stability."

Lin Yuan didn't give them time to digest this and continued.

"What is the biggest hidden danger of a monolithic kernel?"

"One move affects the whole body; if one driver has a bug, the entire system crashes!"

"But the user-space services of the Hidden Dragon System are completely decoupled. Each component runs in an independent sandbox; if any module has a problem, the kernel remains unaffected."

He extended a finger and lightly drew a line on the table.

"In other words, the words that countless people loathe—blue screen, freeze, crash—simply do not exist in the dictionary of the Hidden Dragon System."

An engineer in the front row gasped, subconsciously blurting out,

"No crashes?"

"Correct."

Lin Yuan's answer was only one word.

"And security."

He curled his finger and flicked the table.

"The kernel code size of the Hidden Dragon System is only a few dozen KB."

"What is the concept of a few dozen KB? The attack surface is so small that it's almost impossible to find a place to strike."

"Compared to the behemoths of monolithic kernels, which can have tens of millions of lines of code and are as full of vulnerabilities as a sieve, the Hidden Dragon System has no such security worries."

The conference room was eerily quiet.

This silence wasn't due to an awkward pause, but because everyone's brain was working desperately to digest this information.

Lin Yuan looked at the flushed faces below and delivered the final heavy blow.

"Finally, the point most directly related to our two projects."

He crossed his fingers and placed them back on the table.

"Real-time performance."

"The Spacetime Synchronous Scheduling Engine of the Hidden Dragon System achieves nanosecond-level precision; latency is completely predictable, with no jitter at all."

"Whether it is the hard real-time response required by Fifth-generation Communication or the deterministic scheduling needed by Brain-like Intelligence, the Hidden Dragon System adapts perfectly."

"Furthermore, based on this microkernel, the Hidden Dragon System can be deployed simultaneously on computer equipment, mobile terminals, and even heavy machinery in factories!"

"Using the same system throughout allows for perfect, seamless interconnection between devices, while also reserving space for future upgrades."

He paused for a beat.

"This is also the reason why I chose a microkernel."

Upon hearing this, the software director who had asked the first question was now slumped in his chair, not moving for a long time.

A few dozen KB of kernel code, lock-free synchronization, nanosecond-level deterministic scheduling, component-level hard isolation...

Any one of these things, taken alone, would be enough to keep a top-tier laboratory busy for who knows how many years.

Yet now, Lin Yuan had casually stuffed them all into one system?

The several chief engineers nearby weren't doing much better.

Someone had their hands on the table edge, leaning forward, lips dry.

Someone else was staring blankly at the ceiling, their cognitive framework being dismantled and rebuilt piece by piece.

Lin Yuan took in all these reactions, not continuing the technical pursuit.

"Of course, for something like a system, it's hard for everyone to get an intuitive feel just by me talking about it here."

He leaned back against the chair and spread his hands.

"After it is distributed to you all, go back, install it, run it, and personally experience the difference between the Hidden Dragon System and the operating systems you have used before."

"At that time, it will be more effective than me saying ten thousand words here."

Below, hundreds of heads nodded in unison.

At this moment, no one was struggling with the theoretical controversy of the microkernel anymore.

Lin Yuan had proven himself once with the Photolithography Machine, a second time with chips, and a third time with the underlying theories of Fifth-generation Communication and Brain-like Intelligence.

At this point, when he said that all the problems with the microkernel had been solved, no one present would doubt the truth of that statement.

The matter of the operating system had been simply explained.

The extreme tension in the conference room relaxed slightly.

However—just at this moment, Lin Yuan's body suddenly tilted slightly again.

His slender, fair hand, extremely naturally, reached once more into the ordinary black canvas bag beside him.
