Original: Redis Advanced Practice II How to install Redis on Linux systems I. Introduction Previous article wrote "How to install a VMware Pro virtual machine" and install the Linux operating system on a virtual machine. That was the first step, and with the Linux operating system, we were able to install Redis on that system. Starting with the first article, this is also my official start to learn Redis journey. Talking about Redis, has been exp

With the increasing demand for mobile communication systems, currently, 2G, 2G, and 2G systems and 3G systems that have been put into commercial use cannot meet the increasing high-speed multimedia data business needs of modern mobile communication systems, many countries have invested in the research
6 categories of integrated wiring systems are still commonly used. So I studied the knowledge of 6 categories of integrated wiring systems and analyzed why 6 categories of integrated wiring systems can become mainstream technologies, I would like to share with you some notes here, hoping to help you. Why is the connection to a 6-class cabling system less likely t
Article Title: GTK + and X Analysis Applied in Embedded Linux systems. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
In Embedded Linux, there are many GUI systems, including Qt/Embedded, FLTK, Microwindows, and GTK +. What k
File System of embedded devices
The system needs a method for storing and retrieving information in a structured format, which requires the participation of the file system. Ramdisk (see references) is a mechanism for creating and mounting a file system by using the computer's ram as a device. It is usually used for diskless systems (including micro-embedded devices, of course, it only contains flash chips used as permanent storage media ).
You can se
Determining whether a file system has certain characteristics is an effective way to distinguish and Compare file systems from different aspects. Some common file system features are as follows.2.1 hard linkA hard link is a reference or pointer to a file on a storage volume ). The name associated with the file is a tag stored in the directory structure. This label points the operation to the data of the file. In this way, the same file can be associat
Methods for mutual access between Windows and Linux File Systems
First, we know several file-based services: ftp and sftp, both of which are file transmission services, focusing on network transmission rather than real-time mutual access. Generally, you need to operate the same directory remotely and locally, for example, compile and run the code in Linux by using a variety of powerful ides in Windows. If you compile and write the code in Windows and

Operating System is an old topic. Its appearance and development are of great significance to computer technology. This development is not only reflected in traditional computers, but also plays an irreplaceable role in the embedded field that emphasizes streamlining, high efficiency, and real-time performance.

Competition between open-source operating systems and Windows!Competition between open-source operating systems and Windows!GuideThe technology website ZDNet recently wrote that in an era where users are king, operating systems put down their bodies to gain favor and adopt a free policy, but one exception exists-Windows 10. Such an exception makes many people not
The security of Unix operating systems is well known. However, if you want to say where the Unix system is secure, it is estimated that no one can say why.
1. Different users have different permissions for the same command.
The Date command is a common command in Unix systems. It displays the Date and time of the system. However, different user roles have different functions. If you are a system administrat
Frankly, it is also a chance coincidence, in the postgraduate stage into the field of distributed systems learning. Whether it's large-scale storage or computing, its core is the need to use distributed technologies to leverage parallelism to address data-intensive applications. Recently began to chew this "designing Data-intensive Applications" Tome, the author Martin Kleppmann in the field of distributed data sy
U.S. local time March 15 06:00 (Beijing time March 15 19:00) news that, according to statistics, in the world's top 500 supercomputers, about 60% installed the Linux operating system, compared to other types of operating systems, Linux systems in High-performance computing applications occupy the absolute advantage.
From the beginning as a college student's private hobby, the development of Linux system has
, read the blocks that contain the file content in the order in which the block numbers appear in the disk address table.
Therefore, apart from root, you must never make the disk partition writable to everyone. because the owner and the file access permission are stored in the I node, the owner can set the suid permission for all files as long as he has a write permission for the installed partition, no matter who the file owner is, you do not need to use the chmod () command. You can also avoid

1. Self-increasing primary key
The primary advantage of the Self-increasing primary key is performance. Early database systems often used some numbers, such as ID card numbers and company numbers, as the primary key of the database table. However, soon, you will find the disadvantages.
For example, in the early Hospital Management System, the ID card number is used as the primary key of the patient table. However, first, not everyone has an ID c
Application maintenance is a meticulous task. In addition to requiring the technical staff to be rigorous and responsible, technical personnel are also required to have high processing capabilities and work experience in various emergencies. With the establishment of ICBC's two big data centers, ICBC's core business data is concentrated in the data center, the primary branches focus on the maintenance of peripheral systems, such as the business system
