Came back with black technology

The "dark net" area is actually an anarchic free zone, and the absence of restrictions means that there are all kinds of news, good and bad, and the news is extremely complicated.

Fortunately, as long as you enter the "Dark Net", other operations are the same as the "Surface Net". If you want to know what kind of news, you just need to search. However, Xie Qingyan does not plan to use ordinary methods to search slowly.

Looking at the other world unfolding in front of him, he looked calm, stared at the screen with burning eyes, continued to fly his fingers, entered various filtering conditions on the computer, and finally pressed the Enter key.

In the next second, the screen jumps, and all the entry information related to cutting-edge technology is displayed.

Even after a round of screening, the information is still varied.

There are leaking posts about the secret development of spacecraft in the United States by hackers who claim to have hacked into the US National Security Agency and Aviation Agency; there are analysis drafts explaining the principles of current achievements in the field of bioengineering Remarks: Please purchase the full text; there are some There is no forum showing discussion topics etc.

With the intention of taking a random look and getting to know everything, Xie Qingyan clicked in to see if he was interested.

However, after looking at it for a while, he found that most of the public information did not really talk about the point. He felt that it was only slightly better than the free information that can be found on the surface network, but the professionalism was still not as strong as that in professional academic journals.

And some seem to be used by fishing to deceive people, as long as someone takes the bait, they will make money.

Xie Qingyan frowned slightly, feeling a little disappointed.

I had high expectations for this place from the beginning, but maybe the bigger the expectation, the bigger the disappointment.

But when he thought about it, he didn't know about this place before, but he misunderstood it because of the hearsay in his previous life and the long memory he added to it in his heart.

It's not a bad thing to be disappointed now, it just shows that no matter what you have to explore yourself, you can be more clear, not to mention that things like intelligence collection really have to be done slowly.

I just thought that I have filtered out a lot of bad news just now, and there are still many people digging holes in academic and technological issues and waiting for others to jump in. Xie Qingyan thought that this might have the consequence of destroying those who study, and couldn't help but I am dissatisfied with such behavior.

Of course he knows that people's hearts are unpredictable, especially in this free zone without borders, and the rapid development of the Internet has only been a few decades.

The development of network technology alone means that the relevant monitoring mechanisms and legal provisions are not perfect, and it is easy for criminals to take advantage of loopholes.

Whether it is from the perspective of social development or personal ability, even if he wants to change this status quo, he must take a long-term plan.For now, he only vaguely hopes that there will be a place that can guarantee the rights and interests of scholars.

And just when Xie Qingyan was going to stop reading it and went to look through the high school textbooks to learn about the current high school teaching content, he slipped his hand and accidentally clicked on a strange link.

The screen dimmed instantly, followed by rows of densely packed characters appearing continuously, as if an infinite loop was accidentally created when writing code.

The point is that there is no way to exit this endless loop, as if it has been infected by a virus.

If ordinary people see this kind of characters that keep beating, they are afraid that they will be frightened for a moment, and they will shut down and restart immediately in order to keep the data in the computer from being infected.

However, these seemingly chaotic characters made Xie Qingyan instantly interested.

The characters do look jumbled, as if a crash in the background caused the display to go wrong in the foreground.

But if he thinks that this is the legendary "Dark Web" of Crouching Tiger, Hidden Dragon, Xie Qingyan thinks that maybe this is actually a special encryption method, and only by cracking the "password" can he jump to the inside of the web page.

So now this seemingly inoperable infinite loop interface is the first level to restore order to disorder.

Xie Qingyan thought that the special search conditions just now determined that the content of this link was related to high-tech, and this password blocked most people who do not know advanced computer technology, which means that at least people who have both must be the ones they want. The talent you want.

Although I don't know what's inside, but such a "lock" has been made with so much effort, it is not just for fun, let alone used to deceive people.

Seeing this "treasure box" waiting to be opened, Xie Qingyan couldn't help but raise the corners of his mouth slightly, and immediately started to crack it.

He stared at the computer without blinking, his eyes reflected the blue light of the screen and the characters rushing upwards.

Xie Qingyan doesn't know how other people will crack this password, but for him, fast and effective is the best way.

So without thinking about it, he decided to solve the problem from the source. After typing for 1 minute, another interface appeared on the screen, which was another string of dense codes.

He glanced quickly, looked from top to bottom and then deleted the changes from the beginning. After 10 minutes, he pressed the last button.

The interface available for modification disappeared, and the fast-jumping characters below stopped suddenly, and a black hole appeared in the center of the screen, sucking the surrounding white characters into it, and at the same time, the black hole expanded bigger and bigger.

After finally spreading to the entire computer screen, the black suddenly turned into white, and then the white gradually faded, revealing a shiny green page hidden inside.

"It's done." Xie Qingyan raised the corner of his mouth slightly, and he knew it was a forum when he saw the page design inside.

In the upper left corner, there are two large letters of yc written, and a sentence is added in small font below: the weeds can't be burned, and the spring wind blows and regenerates.

Paired with this green interface, Xie Qingyan smiled instantly. Tough and thick hair is indeed the lifelong pursuit of programmers. Even designing a forum has to use such a metaphor.

Looking down, Xie Qingyan locked his eyes on one of the hot topics, clicked on it, and everyone was discussing about holographic technology.

["Rational Discussion: The Breakthrough of Modern Holographic Technology"

As we all know, holographic technology is a technology that uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of an object, but what we usually know is only a kind of holographic projection that uses methods such as Pepper's ghost and edge blanking to achieve 3D effects technology only.

So here comes the problem. The technical principles are well understood, and there is no shortage of talents, but the development of technology has been stagnant. Is it because of lack of time, a problem with the direction of research, or a problem with material technology?Is it possible to choose another angle to start with, what do you think? 】

Xie Qingyan also has an understanding of holographic technology. He still remembers being shocked by the mirage-like holographic images when he first arrived in Interstellar.

This kind of technology that used to only appear in film and television works has become the most basic configuration in the interstellar era, just like every family has a TV now.

When he first arrived in Interstellar, everything was unfamiliar, and holography, a technology that allows him to easily contact the earth, naturally got his attention.

It was also at that time that Xie Qingyan thoroughly studied the development history of this technology and related technologies. Now that he sees this topic again, he has an inexplicable sense of fate.

Feeling moved, Xie Qingyan watched the speeches of other people for a while, and the direction of discussion was basically on optical holographic technology.

It is true that optical holography is the beginning and even the foundation of holographic technology, but it is only the foundation. In fact, to make a breakthrough in holography, it is not necessary to die on optical holography.

Xie Qingyan thought for a while, clicked Reply and left a message to participate in the discussion.

[Visitor 110: Holographic technology is divided into two steps of light wave recording and reproduction. The difficulty is mainly in the first point of capturing and recording light waves, and the current 3D imaging is not holographic. The key point is that no hologram is formed during recording.

Then, can we think about it this way, when recording light waves in the first step, put aside the real optics, use computer to simulate, obtain [-]D data and [-]D models through computer design or manual production, and further produce the hologram required for holography After the hologram is obtained, the light wave information of the object can be reproduced by diffraction. 】

Xie Qingyan said so far, he felt that he just said a little bit of another way of thinking, even if he didn't say it, someone must have thought of it.

But thinking about it, with the current status of technological development, everyone will definitely not think that someone can surpass traditional optical holography and combine it with digital to advance into computer holography.

After leaving the message, seeing that it was getting late, Xie Qingyan stretched his waist, finished the finishing work and quit the Internet, took out almost brand new textbooks, and began to read his high school courses.

And not long after he quit the network, the YC forum users on the other end of the network exploded.
