Cyber Heroes

"Isn't it right?" Yuki frowned, "Master, it doesn't seem to be the case. In board games...and, in driving, computers are much better than biological brains." "

Xiang Shan nodded: "Yes, but a computer that is good at playing chess can only play chess. It will never understand the matter of'why play chess', or even not necessarily Know that you are "playing chess." If its creator does not give instructions, then it will never want to do the second thing in its lifetime."

This should be... a long, long time ago. NS? Xiang Shan feels that this may be history that happened before he was born. At that time, there was a conductor. He is a 21-trisomy syndrome patient-the so-called "Innate Fool". Perhaps he was born in the Aristocratic Family of music, so he regarded "imitation of commanding actions" as a game, but he did appear on the stage as a "conductor". So is there "music" in his brain?

Perhaps indeed, this pitiful person does know what music is in his heart.

But outside of "music", he can't understand much.

The intelligence bred in the computer is more extreme than this. After all, even the foolish Innate knows that he is hungry and thirsty. I cry if I feel unwell. But even if the chess power is enough to crush the AI ​​of the chess master, it will not produce the idea of ​​"I still need power" or "I just want more computing resources".

"Actually, what a computer can do is never beyond the human brain. Paper and pen calculations...Damn it, you don’t seem to know what'paper' is." Xiang Shan shook the head, Pick up a piece of iron sill and write q and p on the ground.

Two values, 1 or 0, TRUE or FALSE.

Two gave birth to Three, Three Births Myriad Things.

Everything about the computer comes from here.

"What I want to teach you now is called'Boolean operations'." Xiang Shan said: "Humans can perform boolean operations on the ground with a rod of iron, thereby simulating any computer program. ——No, here should be the other way around. Computers are just replacing human hands and writing Boolean formulas on the ground. They are just faster and faster than human handwriting. That’s all."

"This method of calculation was born from the great George Bull. Before George Bull, Leibniz and Babbage were doing the same thing—they tried to use machines to calculate. Babbage may have been for a while. Close to this realm, but after all, it has not been reached. And Boolean is different from all the predecessors. Just like Isaac Newton tried to describe the trajectory of the movement of matter in the dimension of Time and Space, Boolean is trying to describe the movement of mind Trajectory. This is the achievement of splitting heaven and earth apart. Of course, the gap between Boolean algorithm and real human thinking is just like the gap between Newtonian mechanics and the real world. But this is the beginning."

"After Boolean, people realized that gears and levers can perform calculations, neural networks can perform calculations, and non-disconnected circuits can perform calculations. Even a bunch of chemical equipment can also perform calculations-Boolean algorithms. Disassemble a corner of human thinking into something that machines can understand."

The history of humans using circuits to simulate neural networks and perform Boolean calculations is even earlier than the von Neumann architecture-as early as In 1943, neurobiologist Warren McAwalker and mathematician Walter Pitts created the first artificial neural network that can perform Boolean calculations.

Before the time of Boole, there was another inventor named Joseph Jacquard. He invented a brand new loom. This loom can manipulate the needles on the machine with punched cards to weave warp and weft. Similar things have appeared independently many times in history. This "punched card" can even be traced back to the Eastern Han Dynasty in China.

This is the ancestor of the "punch tape" of Turing Machine. It is the most primordial memory with only a few bytes and the earliest "memory" of the machines.

And Hilbert's plan to study pure mathematics prompted the birth of Turing Machine.

Finally, these results finally gathered in the hands of another man named von Neumann.

Here, an unprecedented tool in human history was born. Human society, life, politics, and military have all changed for it.

"However, tools are always tools." Xiang Shan warned his dísciple: "Its essence is still to create thousands or tens of thousands of arms to perform Boolean operations for you. Computers can You can do it yourself with Boolean operations, but the computer is faster-of course, this kind of "fastness" has achieved a fundamental change."

"For general users In other words, you only need to hand over the task to these'several arms', and you can wait for the results. But this is not the practice of internal strength. If there is a success in internal strength, wait until you can maximize the strength of these countless arms. , And even transfer will between these hands."

"So, you must start learning from Boolean operations."

In the field of internal strength, mathematics is "Dao", The Boolean operation is "one".

Dao gave birth to One, One gave birth to Two, Two gave birth to Three, Three Births Myriad Things.

The Boolean algorithm itself is not complicated, it is just an extension of logic. Mathematics at a high school level is almost enough to learn an introduction.

The rest is a lot of practice.

Xiang Shan took some time to explain the essence of these questions to Yuki, and then wrote an exercise book directly in his mind and transmitted it point-to-point to Yuki's brain chip.

Yuki left the room with a heavy step.

Xiang Shan is satisfied and nodded. There was a feeling in his heart-he had wanted to do this kind of thing a long time ago.

I don't know why, maybe it is the influence of past experience on him?

He is quite happy anyway.

………………………………………………………………………………

Yuki finally finished the exercises, Back to his room.

Then he found that the atmosphere in the room had completely changed.

Xiang Shan closed his eyes and faced the terminal like meditation. On the terminal screen, countless symbol refreshes generally appear and disappear. More code is covered on top of the code.

The dog-shaped prosthesis connected to the terminal is doing various actions.

Xiang Shan comprehend the meaning of each line of code, and then replaced the original code with his own code.

He wants to try to master this unseen component.

"Yuki, have you finished the exercises." Xiang Shan still maintains the original posture: "Is your brain chip a type that can be removed at any time? Is it not convenient to show me a slice now? "

Yuki nodded: "It can be..."

He lowered his head and opened his back skull. Then, a spare chip popped out.

There will always be two or more driver chips for the prosthetic body. When one of them crashes due to a bug, the other one will instantly take over the body, and at the same time, the one with the bug will quickly watchdog and re-enable it.

It is different from the one-piece skull of Xiang Shan. Yuki's modern artificial skull is easy to open.

Yuki handed his spare chip to Xiang Shan: "Master, what are you doing?"

"I'll get it done soon. I'll talk to you when it's done." Xiang Shan shook the head. Didn't notice this at first, it was indeed his carelessness. In this era, the superiors' deprivation of the life and death of the weak is more serious than he imagined. He only discovered that Dr. Schultz had asked himself to go online, so he naively concluded that none of the overwhelming majority cybernetics were connected to the Internet at all times.

When Yuki was accepted as a dísciple, he just wanted to avoid the surveillance route in the village.

But the previous words of the mayor reminded him.

No matter what society is like, never underestimate the plundering of people by tyrants.

In fact, there should be a frequency band that the ordinary person does not know or cannot use at all. In this non-civilian frequency band, all the prostheses are connected to the network-but the users of the prostheses don't know.

The only good news is that the current "real ruling groups" seem to be understaffed, or have other objective difficulties, and do not monitor everyone all the time.

——Hey...it should not have been this serious in the past.

——However, I should have imagined this extreme state.

"Practicing martial arts without practicing martial arts will end up futile." At the beginning of the design, internal strength included the idea of ​​fighting against this state.

Therefore, after regaining some internal strength for himself, Xiang Shan built Yuki the power to resist external evils and cleared the back door in the chip.

Soon, Xiang Shan retrieved the entire chip. Sure enough, he did not expect that in this thing, there were indeed several protocols that he hadn't seen before, pointing to certain ports with signal transmitter capabilities.

This port uses shortwave communication. The signal is relatively weak and the data transmission capacity is limited. It is estimated that only low-quality audio or images can be uploaded.

But this means that the ruler can indeed spy on any individual at any time.

"Very good, at least fortunately, there is no army and police in this era, and the lords have too much discretion...they can only realize that I may be a knight."

Xiang Shan soon wrote a firewall in Yuki's chip, which made it deny remote access to that specific port and sent fake images. Then he erased several other agreements.

Of course, before doing these things, he made a backup first.

Xiang Shan returned the chip to Yuki and said: "Try it yourself and tell me what's wrong. If there is no problem, please do me a favor later."

Xiang Shan himself now drives the prosthetic body by the cheap chip presented by the mayor. And in that driver chip, there may also be a backdoor. Xiang Shan’s artificial skull does not open and close like Yuki. If there is no special tool, he must rely on the help of others to take out the inserted chip.

This is equivalent to exposing one's brain to other people. Xiang Shan must have a trusted assistant to dare to do this kind of thing.

In addition, he must also put an end to the situation that "the assistant was remotely controlled by the brain in the middle of the process, and a trembling finger poke into his brain". Therefore, he gave priority to Yuki to prepare "initiation".

While Yuki transfers his math work to Xiang Shan for inspection, he runs and jumps according to Xiang Shan's instructions to test whether the driver chip has a BUG.

Humans have learned "don't pursue programming without bugs" very early. As long as the program can run, it doesn't matter if there are bugs.

High level languages ​​can be roughly divided into "type-insecure languages", "type-safe languages" and "strongly standardized languages" according to the classification of "type theory". Strongly standardized languages ​​can guarantee "no error". This type of language can give a unique result for any program and stop, and it will never fall into an infinite loop. But it is precisely because the strongly standardized language has abandoned the concept of "circulation" and lost Turing completeness, so any errors in the system are not recognized at all and not allowed to run.

To put it simply, a strongly standardized language means "the program will never go wrong when it runs, and if there is a mistake, it will not run."

The knights tend to use "type-unsafe language". Users of this language are often confused about "The code I wrote can't run? Why is this? The code I wrote can run? Why is this?" This language is easy to produce "unpredictable errors"-this "unpredictable" can be said to be doomed by mathematics itself, before the program runs, even the writer himself cannot predict.

Of course, this kind of "difficult to understand" is the same for the enemy.

Xiang Shan would rather be troublesome, do a few tests before writing any program, and choose "type-unsafe language".

But Xiang Shan's level seems to be really good. Yuki's driver chip can still control the prosthetic body normally.
