Cyber Heroes

Xiang Shan was standing in front of a printer with his arms folded, waiting for the document to be printed. His eyes were bloodshot, his hands were clasped in front of his chest, and one side of his body was leaning against the wall, looking somewhat weak.

But his look was full of courage.

Xiangshan was in this state when Yawgmoth and David found him. He looked haggard, as if he had worked overtime for a long time and was about to die suddenly, but his aura would make people mistakenly think that he was about to take over the world.

David handed the document he got to Xiang Shan: "Hey, Shan, the information you want. Don't spread it randomly these days... Maybe it will be lifted in the park next week, but it's still a bit sensitive right now."

Xiang Shan narrowed his eyes and flipped through the pages quickly.

Soon, he became energetic: "Sure enough...it's actually like this..."

"Really?" David craned his neck to look. The information in Xiangshan's hand comes from the core components of the complete machine.

These components are divided into two types, one is a simple artificial diamond plate, and the other is a foam-like artificial diamond with a large number of voids inside.

Scientists still debate the purpose of these components. Some speculate that this should be some kind of optical component, but no one knows yet how they are supposed to work.

"I see... the 'codebook' is the real body..."

Xiang Shan sighed.

"Codebook?" David was a little confused: "What are you talking about?"

"After chatting with Yingjia, I realized a problem, that is, the two-dimensional symbol matrix used by aliens is not excellent according to the standard of 'encryption algorithm'. A symbol will be affected by up, down, left and right at the same time. This is a restriction on expression." Xiang Shan pressed his forehead: "But the aliens still used this algorithm."

Yawgmoth was very surprised: "So why?"

"Either those aliens are stupid. Or they have more than 200 megabytes of information that must be transmitted... In any case, this is the bottom line. These 200 megabytes of information must be transmitted no matter what the cost. But , the permanent storage devices they can create can only record less than 300 megabytes of information, and only a few dozen megabytes are left. So what should we do?"

Yawgmoth and David were stunned: "What should we do..."

"Use the two hundred megabytes of information as a 'codebook', and then write down the algorithm for the remaining tens of megabytes of information, and use the algorithm to replace the two hundred megabytes of information with the information necessary for the small robots to replicate themselves..."

"Xuanji Tu" is not a compression of "any eight thousand poems", it is not even a compression of anyone else's poetry, but it was that way from the beginning.

Two-dimensional word games are very different from daily one-dimensional human language. Language is also affected by an "extra dimension". Therefore, each of the nearly 8,000 poems is just a mediocre work if taken alone. But the establishment of this word game is a remarkable thing in itself. Its power lies more in form than in specific content.

It is not a compressed poem, it is created in this way.

David waved his hand: "Wait a minute, wait a minute, this is outrageous! You mean, the aliens actually only have a few dozen megabytes of space to leave symbols, so they simply left a set of rules, from that 'must pass Did you get specific data from the 200 megabytes of information?"

Xiang Shan nodded: "I'm afraid that's it."

"This is so fucking outrageous!" David shouted: "The problem we are facing now is how do those aliens compress such a complex industrial process into three hundred megabytes of text? And then you tell me, the aliens The available space is even less, because among these 300 megabytes, a fixed 'codebook' must be added..."

"As long as their algorithm is good enough and the compression rate is good enough, this codebook can actually contain a lot of content." Xiang Shan said.

"No, three hundred megabytes. No matter how high the compression rate is, it is impossible to compress such a complete set of complex industrial data losslessly! Design drawings, assembly processes, metal smelting..."

"Those are all unnecessary contents, David." Xiang Shan laughed out loud: "Non-essential contents..."

"ah?"

"Cells will not put 'all the data about the cell' into chromosomes." Xiangshan laughed: "This is the conclusion! You are absolutely right! Ogun is a large cell!"

"Huh?" David was confused now: "That's just a metaphor... a metaphor..."

"You have grasped the core concept." Xiang Shan said: "Although I have some superficial understanding, I only found out after asking professionals yesterday - all the information of 'cell' is not only included in the nucleus. For example, 'cell' 'This structure itself is not included in the information of the cell nucleus."

Yawgmoth was stunned: "Could it be that..."

"Those robots themselves can be used as blueprints." Xiang Shan laughed loudly: "Those robots themselves are the best blueprints... There is no need to store the most detailed industrial drawings. Most of the parts of these gadgets are universal! Universal! Just need By measuring yourself, you can read a lot of information!”

A thunderbolt flashed through David's mind: "But...but...what if there is an error?"

"It can't be spliced? Or the life of the machine has been reduced?" Xiang Shan twisted his neck and soothed his cervical spine: "Or the accumulation of errors has caused the overall machine to be one size larger? Or one size smaller?"

"It's possible..."

"Then it won't work! Then the lifespan will be reduced! As long as the size of the machine cannot match the fixed equipment including the track, then just scrap it!" Xiang Shan said: "Then recycle it! You said it , these robots only have no shortage of time. As long as their instructions do not include 'forcibly matching fixed equipment of inappropriate sizes', this set of operations can be maintained for a long time!"

"This is what you said, guard against... guard against..."

"'Fool-proof design'."

"Yes, 'fool-proof design'!"

David was stunned: "Are you speaking Chinese? What is the proper term for 'fool-proof design'?"

Yawgmoth explained: "Structurally designed to prevent idiots from installing it incorrectly."

"The so-called 'fool-proof but not stupid-proof, great strength can produce miracles'... No matter how excellent the fool-proof design is, it cannot prevent fools from forcibly installing it. But as long as those robots do not have enough power during installation or trial operation to break through the material strength, or there is If the program limits the output, then there will be no problem at all." Xiang Shan's eyes seemed to be shining: "It's just low efficiency, it doesn't matter at all..."

Cells don't need to be built from scratch, and Ogunne's robots don't need to make copies of themselves from scratch.

They are blueprints themselves.
