The development of technology is actually traceable. no matter how advanced or mysterious the technology is, it is in practice-> experience-> theory-> practice->... in the process of development. The reason why I wrote this series of articles today is not to show off how many cows I have. Of course, it is not to pretend to be B. I still have the self-knowledge of "days outside, people out of the world. My purpose is actually very simple:1) I have lear

The current stage of work I still focus on technology, although the future is not like a technology to earn a living, but now also have to take the time to improve the level of personal technical awareness, a general list of personal efforts: 1, are classic books, back-end SSH framework, the front html+css+ At least three of the classic JavaScript books; recently read 3 non-programming convenient good book,

VXLAN Technical Analysis-(1) VXLAN Brief introductionVxlan Brief IntroductionThe vxlan,virtual extensible LAN, as the name implies, is an extended version of VLANs. Vxlan technology is primarily used to enhance the network's ability to expand in cloud computing environments.The Vxlan uses UDP packets to encapsulate the Ethernet message, which enables cross-IP data transmission with a UDP port number of 4789

databases. Distributed databases are the final means of Site Splitting. They are used only when the data size of a single table is large. The database sharding method that is more frequently used by websites is database sharding, where data of different businesses is deployed on different physical servers. (8) Use nosql and search engines. They provide better support for Scalable Distributed features. (9) Business Splitting: splits different business

uncertain, and the service recovery time is relatively long, which is a shortcoming of the recovery mechanism. Restoration is usually used for mesh networks to make the best use of network capacity resources. Both protection and recovery can adopt the reselect routing mechanism, but both have their own advantages and disadvantages. The protection technology has a short switching time, but the network resource utilization is low. The restoration technology greatly improves the utilization of net

pipelines are generally linear, but it is often helpful to insert a copy of the data stream from the middle into a file, or send it to a terminal window. This can be done with the tee command, which sends its standard input both to the standard output and to a file specified on the command line. You can think of it as a tee on a pipe.For example, the following command sends the output value of date to the standard output and redirects the output to the Date.txt file:Date tee ./Date:notoginseng:

Article Title: some technical information about NICs in Linux (1 ). 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. For those who want to learn more about how NICs work, how to use existing drivers, and try to write their own drivers for NICs that are not currently suppo
