Chapter 114 MAC and Not Opening System Permissions

When it comes to the permissions of the mecha system, I have to talk about the current various systems. The open system permissions and the open system are not the same thing. The representative of the open system permissions is the Android system, which is also the system with the largest market share. , the English name andiord, this system is open to system permissions, to put it bluntly, you can directly download various software in various browsers, and at the same time you can use various software to modify various system parameters.For example, my Android phone was blacked out by someone else’s router when I was surfing the Internet. If it is an ios system, there is no other way. Restored and still blocked by other routers.But if my mobile phone is an Android phone, I can modify the MAC address of the Android phone through the software or the operating instructions of the system developer. Since the router uses the MAC to identify each connected machine, after modifying the MAC address of the Android phone, The router thinks that the newly connected machine is a new machine, and will no longer perform the blocking operation on the previously blocked mobile phone.The ios system is a system that does not open system permissions, that is to say, if users want to download software, they must download it through the store that comes with IOS, and it cannot be downloaded in a browser.

As for the mecha system, Liu Yun intends to not open system permissions like IOS. Users can only download software through the store of Yunfan Technology Company, and do not give users any permission to modify system data.The main reason is that things like mechas are related to personal safety. Once users modify data privately out of curiosity, it is likely to cause system instability. Once a bug occurs in the system, because the system is controlled by mechas, Once an accident happens to the people in the mecha, it is likely to cause serious injury to the people in the control cabin.If the mecha just fell to the ground, it’s okay to say that the operator inside the mecha will be injured at most, but if the mecha is running or the mecha is driving in the shape of a car, then the risk of a bug in the system is quite high. .Just imagine, if the mech is driving on the road with small wheels in the mode of a car, at this time the system causes a BUG due to the user modifying the data, and the light tap will damage the mech, but if it is serious, it will die, although The defense of the mecha is better than that of a car, but it cannot prevent the shock caused by it, and the mecha cannot stop the force of the shock, and it is easy to cause irreversible damage to the people in the cockpit.

This is the fundamental reason why Liu Yun does not intend to open the system permissions. The reason is very simple, because the operation of the mecha cannot tolerate the slightest mistake. Once the mecha system makes a mistake, it may endanger people's lives.Opening system permissions not only means that users may modify system files and cause system failures, but software downloaded by users may also cause damage to system files. Once system files are damaged, it is okay if the damaged system files are not very important, just a reminder If any files are missing, you need to copy the missing system files to the original location in safe mode, but if the missing system important files are likely to cause the mecha to fail to operate normally, this is very scary.Because the lack of system files does not necessarily cause problems at any time. Once a fatal system problem occurs when the mecha is running, it is very dangerous. You must know that the mecha is not a computer. If the computer is broken, it is nothing but to delay using the computer. A broken mecha will endanger people's safety, so the issue of system permissions must not be let go.

Not opening system permissions does not mean not giving mech buyers some extra options.

Take the bending action of the mech as an example, because the purchaser of the mecha is engaged in different professional activities or wants to use the mecha for different activities, then it is necessary to give the user of the mecha some additional options at this time. Let the user of the mecha have more bending movements, so that the operator of the mecha can complete various activities more conveniently.

Of course, providing redundant permissions to mecha users does not mean opening up system permissions to mecha users. Such additional functions are just to present the previously castrated functions of mechas to mecha users again. That's all.It means that the mech itself has made a lot of state settings for the mech's bending action, for example, there are 10 degrees of bending, 20 degrees of bending, 30 degrees of bending, 45 degrees of bending, and 60 degrees of bending. Waist, there are 70-degree bending, 80-degree and 90-degree bending, but in order to make the mech run more smoothly, most of the bending state of the mech is directly castrated, leaving only the 45-degree of the mech The bending state and the 90-degree bending state of the mecha.When users need other bending states, they can enter the system according to the user manual to find castrated or hidden bending states.Users can add various bending states according to their needs.For example, a user wants to add a 30-degree bending state. At this time, he can enter the system, find the option of 30 degrees, and mark √ in front of this option. At this time, when using the mecha, the mecha can achieve 30 degrees. Bending action, if you don’t want to use this 30-degree bending action, you can remove √ in front of the 30-degree option, and no longer select it. At this time, the mech’s 30-degree bending state will disappear.However, the user cannot operate the 45-degree bending state and the 90-degree bending state of the mech. After it is turned on, the control of the bending action will start with the startup of the system. This is called a system process. Even if the mech does not use the bending action of the mech at this time, but because the process of bending the mech has already started, even if the user Do not use the system's bend process, which is still on.And this bending process includes three states that cannot be added, deleted, checked, and modified. These three states are bending movements of 45 degrees, 90 degrees, and 0 degrees.If the mech user wants to use a 45-degree bending action, the 90-degree bending action will be added at this time, and the added 30-degree bending state will be added to the system's bending process, so that the bending The system process has one more state.

But this extra 30-degree bending state is not permanent. It is just a temporary parameter given by the system to the bending process. The life of this parameter only takes effect when the system is running this time. When the system restarts, this temporary Sexual parameters will disappear, but other parameters will not change.
