Chapter 1857: Sandstorm


When you travel back and forth, you have to give them some gifts when you meet them. What is suitable? Of course it is a personal computer. The gift is small, easy to carry, expensive, and the cost is not high. It is a suitable gift for friends. gift.
Qin Guan has always used this kind of computer as a communication tool. Of course, it still has actual value, that is, there is a problem in the system.
For computers, viruses and vulnerabilities are two lingering topics.
The two are not the same. A virus is a piece of code with self-replication capabilities. As long as it runs, it will continue to replicate itself. Some viruses may also have destructive capabilities, such as formatting the hard drive, or destroying BOIS to make the computer unable to start. and many more.
Vulnerabilities are different. Vulnerabilities are caused by imperfect system design. It has no external manifestations of its own. It is hidden in the system. Only those who do good things will start tossing around when they have time, and then discover the system. Loopholes.
Vulnerabilities are not harmful until they are discovered, such as leaking data leaks, etc. Generally speaking, those who find the loopholes will be complacent and publicly announce that at this time, the system designer can quickly fix the loopholes.
This is the difference between the two.
Vulnerabilities can only be called loopholes if they are discovered. If they are not discovered, they are normal procedures.
Of course, the personal computers given to these people have loopholes. When needed, oneself may enter the system at any time after the other party is connected to the system to search for internal confidential documents. It can be said that if the other party sends these to them If your computer is used as a personal entertainment computer, that's nothing. If it is to be used as a personal work computer, it can be used by oneself at any time.
If they find a system loophole casually, they can fool it, we don't know. Besides, loopholes are very secretive, and most people can't find them at all.
In fact, many of the loopholes in the system are deliberately left behind. The designers of those systems set aside some backdoors to test the system. Some of the backdoors are closed, and some are opened, which is a loophole. Up.
As long as you use the other party's operating system, you will definitely be under the other party's monitoring. This is no need to think about it. So, look at the parallel time and space. Windows dominates the mainstream, but government departments, military agencies, etc. , The use of the Red Flag operating system based on the open Linux kernel is indeed out of the requirement of confidentiality. The open source kernel and all the codes are known to you. This system security is the best.
I slept beautifully on the plane and soon returned to the motherland. After all, the Gagarin Aircraft Factory is already very close to the motherland. "President Qin, we will continue to fly and land at the Governor's Mansion in Zhili." Just when Qin Guan received a cup of coffee, he heard what Xiucai said.
Need to continue flying south for hundreds of kilometers. Why?
"Sandstorm." General Lin said to Qin Guan.
If it were not for the sandstorm, now they have entered the descending route. Now, looking down from the passenger plane, you can see the entire capital, which has been covered by the sky of yellow sand, and the capital is shrouded in gray. It is difficult to see clearly, under this kind of visibility, the landing on the Capital Airport is full of danger.
In winter and spring, the capital is very prone to sandstorms. However, it is the first time that sandstorms have covered the entire capital.
Qin Guanyou inexplicably thought of smog, nature is the most harmonious, and any disrespect for nature will be punished.
The billowing sandstorm, like the sea water in the ocean, rolled forward, and from above, you could clearly see the signs of the turbulence, like a demon.
"Sandstorms do not exist right now, they have existed since the Yuan Dynasty at the earliest time." General Lin said.
When he said this, Qin Guan felt that the grassland hero in his brain was about to move. The era of Ben Khan was the greatest era!
"We need weather experts to manage." Xiucai sighed from the side.
Brick family, after hearing the words of Xiucai, Qin Guan also felt inexplicable emotion in his heart. If human beings want to develop, they will definitely destroy the environment. If they want to restore a green mountain and green water, they can only de-industrialize.
Look at Niu Country. The fog in the former capital is famous all over the world. Later, Niu Country decided to de-industrialize and relocate its industry to developing countries. Niu Country itself only engages in tourism and other non-polluting industries in the country. .
The results of it? Can there be enough jobs by relying on tourism and the like? Needless to say, the country of cattle, even the country of eagles is not good. That crazy president has been chanting the return of industry all day. What is that for? Isn’t it to increase the employment rate? At that time, the industry of Eagle Country began to hollow out, and even a bicycle could not be made. Without any supporting industrial chain, everything was in vain.
Without industry, there will be no employment rate, and there will be no national development. With industry, it will pollute the environment. This is a dead end. The large chimneys are emitting exhaust gas into the air, causing serious air pollution.
Now, it is still an era of raging sandstorms. The main cause of sandstorms is the destruction of vegetation. The strong wind blows up the dust. In order to control the dust, it is necessary to plant trees and afforestation, not only in the capital, but even in the northwest. Extensive tree planting.
In later generations, sandstorms have been brought under control and rarely occur. However, another kind of silent atmospheric disaster has occurred, that is, haze. Because there is no strong wind, the particles in the air cannot be dispelled. Floating in the atmosphere, forming severe haze weather, causing severe respiratory diseases.
The de-industrialization of Rainbow Nation was successful, and there was no pollution in the country. What happened? Successfully retreated from developed countries to developing countries.
Han Guo absolutely cannot follow this path.
and many more!
Qin Guan thought of something between the sparks, isn't this a good opportunity? Lobby the superiors to develop nuclear fusion energy. The pollution in the atmosphere, mainly solid particles, comes from the combustion of fossil fuels, such as power stations, such as coal-fired boilers for heating in winter, and even automobile exhaust. These will all be in nuclear fusion technology. After the breakthrough, it has completely become history!
The ultimate clean energy is definitely nuclear fusion.
