Super Weapon Swap System

When you visit back and forth, you always have to give them some gifts. What's suitable for them? Of course, it's a personal computer. The gift is small, easy to carry, high price and low cost. It's a suitable gift for friends.

Qin Guan has always regarded this computer as a communication tool. Of course, it also has practical value, that is, there are problems in the system.

For computers, viruses and vulnerabilities are two lingering topics.

The two are different. A virus is a piece of code with self replication ability. As long as it runs, it will continue to replicate itself. Some viruses may also have destructive ability, such as formatting the hard disk, destroying Bois, making the computer unable to start, and so on.

The vulnerability is different. The vulnerability is caused by the imperfect system design. It has no external performance and is hidden in the system. Only those who do good things start to toss around when they have time, and then they find the vulnerability of the system.

After discovery, the vulnerability is harmful, such as overflow data disclosure. Generally speaking, the person who finds the vulnerability will publicly announce it with complacency. At this time, the system designer can quickly repair the vulnerability.

This is the difference between the two.

A vulnerability can only be called a vulnerability if it is found. If it is not found, it is a normal program.

Of course, there are loopholes in the personal computers given to these people. When necessary, our party may enter the system at any time after the other party has connected to the Internet and look for internal confidential documents. It can be said that if the other party takes these computers given to them as personal entertainment computers, it's nothing. If we want to use them as personal work computers, Then you can be used by your own side at any time.

If they find a system vulnerability, they can fool it. We don't know. Besides, the loophole is very secret and ordinary people can't find it at all.

In fact, loopholes in the system are often deliberately left by people. In order to test the system, the designers of those systems have specially left some back doors. Some back doors are closed and some back doors are open, which is a loophole.

As long as you use the other party's operating system, you will certainly be under the other party's monitoring. You don't have to think about it. Therefore, look at the parallel space-time, windows occupies the mainstream. However, government departments, military institutions, etc. use the Red Flag operating system based on the open Linux internal core, which is an open-source kernel for confidentiality, All the codes are known by themselves, so the system security is the best.

After a good sleep on the plane, he soon returned to his motherland. After all, Gagarin aircraft factory is very close to his motherland. "Mr. Qin, we will continue to fly and land at Zhili governor's house." when Qin Guan received a cup of coffee, he heard the scholar's words.

We need to continue flying hundreds of kilometers south. Why?

"Sandstorm," general Lin said to Qin Guan.

If it weren't for the sandstorm, now they have entered the descent route. Now, looking down from the passenger plane, you can see that the whole capital has been covered by the yellow sand. The capital is shrouded in gray and can't see anything clearly. In this visibility, the landing on the capital airport is full of danger.

In winter and spring, the capital is very prone to dust storms. However, it is really the first time that dust storms cover the whole capital like this.

Qin Guanyou inexplicably thought of haze. Nature is the most harmonious. Any disrespect for nature will be punished.

The rolling sandstorm, like the sea water in the sea, rolled forward. From above, you can clearly see the signs of surging, like a devil.

"Sandstorms don't exist now. They have existed since the Yuan Dynasty," said general Lin.

When he said this, Qin Guan felt that the grassland heroes in his brain were ready to move. Ben Khan's era was the greatest era!

"It needs a meteorologist to manage it." the scholar sighed aside.

Brick family, after hearing the words of scholars, Qin Guan also had inexplicable feelings. If human beings want to develop, they will certainly destroy the environment. If they want to restore a green mountain and green water, they can only go to industrialization.

Look at NiuGuo. The fog in the former capital is famous all over the world. Later, NiuGuo decided to industrialize and move its industry to developing countries. NiuGuo only engaged in tourism and other non polluting industries in China.

What happened? Can there be enough jobs by relying on tourism and so on? Needless to say, the country of cattle can't even the country of eagle. The crazy president has been shouting for the return of industry all day. What's that for? Isn't it just to increase the employment rate? At that time, the industry of Eagle country began to hollow, and even a bicycle could not be built. Without any supporting industrial chain, everything was in vain.

Without industry, there will be no employment rate and no national development. With industry, the environment will be polluted. This is a dead end. The big chimneys are discharging waste gas into the air, causing serious air pollution.

Now, it still belongs to the era of sandstorm. The main reason for sandstorm is the destruction of vegetation and the sand and dust blown by the strong wind. In order to control the sand and dust, it is necessary to plant trees, not only in the capital, but also in the northwest.

In later generations, dust storms have been controlled and rarely occur. However, another speechless atmospheric disaster has occurred, that is, smog. Because there is no strong wind, it is unable to disperse the particles in the air and constantly float in the atmosphere, forming bad smog weather and causing serious respiratory diseases.

The deindustrialization of rainbow country is very successful. There is no pollution in China. What is the result? Successfully returned from developed countries to developing countries.

The Han state must not take such a path.

wait!

What did Qin Guan think of in the spark of electricity and light? Isn't this a good opportunity? Lobbying superiors to develop nuclear fusion energy, ah, the pollution in the atmosphere is mainly solid particles, from the combustion of fossil fuels, such as power stations, such as coal-fired boilers for heating in winter, and even automobile exhaust, which will completely become history after the breakthrough of nuclear fusion technology!

The ultimate clean energy is definitely nuclear fusion.
