What we want to do is to be able to isolate the scope of the instruction from the external scope, and then map the external scope to the scope within the instruction. You can do this by creating a isolate scope. In this case, we use the scope configuration of the i

Vswitch PVLAN configuration procedure To create a VLAN, run the following command: [2016] vlan-id: Set the VLAN type to primary. The command is as follows: [2016-vlan100] isolate-user-vlan enable adds ports to a VLAN. Both the primary vlan and the secondary vlan are the same) Run the fol

implementation can change during compilation. However, this solution has very limited functions. For example, a system cannot accommodate multiple implementations, but different implementations cannot change dynamically. It is strange to use the WritePrinter function name to implement the function output to the disk.3. The class library can be reused separately. However, applications cannot be reused without the class library unless a class library that implements the same interface is provided

Introduction to Linux Namespace We often hear that Docker is a virtualization tool that uses Linux Namespace and cgroups, but what is Linux Namespace how it is used in Docker, where many people are confused, Let's begin by introducing the Linux Namespace and how they are used in the container. Concept Linux Namespace is a feature of kernel that isolates resources from a range of systems, such as PID (Process ID), User ID, network, and so on. In general, many people will think of a command chroo

the simple separation interface method discussed above has very limited effect on the dependency relationship dissolution. Java provides pure interface classes, which do not include any implementation code and can better isolate two modules. Although this pure interface class is not defined in the C ++ language, all member functions are pure virtual functions and abstract classes do not contain any implementation code, which can play a role similar t

Dependency inversion (dependency inversion principle) it can be seen that the simple separation interface method discussed above has very limited effect on the dependency relationship dissolution.

responsibility encapsulation, easy to reduce the system of duplication of code, reduce the coupling between modules, and conducive to future operability and maintainability. AOP represents a horizontal relationship, if "object" is a hollow cylinder, which encapsulates the object's properties and behavior, so the aspect-oriented programming approach, like a razor, cuts these hollow cylinders open to get inside the message. And cut the cut, which is called "aspect". Then it will be skillfully sei

The installation of the FTP site seems to be not a difficult thing, we do not need the help of any external tools, only the use of Windows Server system with the IIS features, you can easily set up an FTP site. However, the FTP site installed in this way not only allows any user to anonymous access, but they can also the home directory of the FTP site to "read" and "write", so that the content stored in the FTP site is not security. So how can we make a successful FTP site, not allow users to ac

a system-level virtual machine becomes VMM (virtual machines Monitor)For both hardware and software virtualization, there are advantages and disadvantages of the two technologies. For hardware virtualization, we discuss full virtualization and partial virtualization. Because most of the virtualization technology now Xen, KVM support both of these. Hardware virtualization is basically a virtual system on a host, and the virtual machines are invisible to each other. This will obviously result in

have problems. 5. virtual machines are considered as second-level hosts, which have similar features and run in a similar way as physical machines. In the next few years, the difference between virtual machines and physical machines will gradually decrease. 6. When it comes to the virtual field, the least privileged technology has not been paid due attention or even forgotten. This technology can reduce the attack surface and should be used in physical and similar virtualization environments. M

Note: 1. On an Ethernet switch, the Trunk and Hybrid ports cannot be set at the same time. 2. The Trunk port cannot be configured with the isolate-user-vla

conductive interference. Both can be used to handle EMC and EMI problems. Magnetic Beads are used to absorb ultra-high frequency signals, such as RF circuits, PLL, oscillating circuits, and ultra-high frequency memory circuits (ddr sdram, Rambus, etc.). They must be added to the input part of the power supply, inductance is a type of energy storage component used in LC oscillator circuit, medium and low frequency filter circuit, and its application frequency rarely exceeds the error 50 MHz. ★Ge

K data buffer, then Port all the indexes in their system to the 32 K tablespace. In this way, the Oracle9i database can read a considerable number of index node branches in one disk I/O, thus reducing the system pressure and improving the overall performance. 　　Allocate objects to multiple block buffers In this way, we can create multiple data caches in the Oracle database. How can we decide what data to store in these data caches? Let's first look at some more common techniques.

But it does have a big advantage: The process interface can always be used to isolate the organization of a large system from the client program-even when the interface is not considered in the early stages of design.Isolated or not isolatedIsolation introduces some overhead. Common reasons for choosing whether to

. In fact, the basic responsibility of describing the three layers of this is relatively easy, but different people how to understand and design these three layers are different, anyway, I have seen a lot of different hierarchical structure, each has its own characteristics, from a certain point of view are very good, but all seem a bit messy, because there is no unified architecture model to support , the code is filled with an understanding of the layered architecture, such as: often see
