choose a Linux starter book, you can install a Linux virtual machine, repeat the practice as the main means, a book well thoroughly understand, the focus is thoroughly understand, then you get started.So what do you need to know?Here are some things to know:1, understand the Linux FHS, this is the architecture of Linux, understand the general principle2, repeat 60 common Linux Foundation, command, Mount3, TCP/IP protocol, network configuration related knowledge4. SSH principle and application5,

As this picture shows, in the Spring IO framework, Spring boot is in the execution layer to see the official explanation for this layer: The Spring IO execution layer provides domain-specific runtimes (DSRs) for applications built on the IO Foundation modules . A DSR may run standalone without requiring deployment to an external container. Or cite the official words to illustrate what spring boot does primarily: Spring Boot reduces the effort needed to create Production-ready,

market share, and then the development of a certain difficulty, so that 2016 is a transition year. When Pat Gelsinger visited China in 2016, he said: "Cloud computing is new hardware."Cloud computing is a new hardware, this sentence in 2016 to understand there are some difficulties, now by the year 2018 VMware launched Project Dimension can clearly understand the meaning of this sentence. In the past, VMware's virtualized objects were X86 servers; today, VMware's new virtualization object is th

the series of actions that DTE and DCE double on each circuit. In this layer, the unit of data is called the bit (bit). Typical canonical representatives belonging to the physical layer definition include: Eia/tia RS-232, Eia/tia RS-449, v.35, RJ-45, etc. Second layer: Data link layer (datalinklayer)On the basis of providing the bit-stream service in the physical layer, the data link between adjacent nodes is established, and the data frame (frame) is transmitted without error on the channel th

ISO8583 specification is a bit difficult, online also has a peer for our translation of the Chinese version of the ISO8583 specification, So my goal is to reach the reading of this article can be known to ISO8583, but also know the reason why, so that the basic non-contact with it before the people can also achieve the mastery of ISO8583 message specification. Well, it's time for us to turn to the chase. At first, the financial system was only IBM's big companies to provide equipment, such as v

The greatest risk to software security is the nature of the opacity of the tools and processes, and the potential for false negative errors to be covered by different inspection techniques (such as automated dynamic testing). While the Security software Development Lifecycle (SDLC) has many relevant best practices, most organizations still have a tendency to rely primarily on testing to build secure software. The most serious side effect of the curre

---- 1110 1011 ----- 1010 1011 ----- 0010 0000 ---- 010 Therefore, T (x) = (x6+x5) + (x) =x6+x5+x, i.e. 1100000+010=1100010 If the transmission is correct, T(x)　　 x6+x5+x ------ = --------- = x3+x2+x, G(x)　　 x3+x+1 No formula. Looking back at the vertical division above, if the divisor is 1100010, obviously in the third 1 o'clock of the business, can be done. The above calculation process helps us to understand the CRC concept. But direct programming to achieve the above algorithm, not onl

design of swarm, understand its service discovery, service orchestration, and then build swarm cluster environment, then adjust our microservices to adapt to swarm, and finally deploy them in the swarm cluster. 7th Chapter Service Orchestration-kubernetesThe whole idea of kubernetes learning is also from concept to cluster building and finally to micro-service deployment. But because of its leadership in the field of service orchestration and its high threshold. We peel it into three parts, the

Most of Microsoft's own products are using this platform for research and development management, which also provides good support for agile development. In the process of collating user stories, we
