Recently, I have been working on a project, which is a large multi-node deployment project. Several versions have been made, and many technologies and frameworks have been used.
Management tools and agile practices are also used. I am not here to talk about the project, because I recently read some recruitment information, combined with some knowledge used in the project and

Open source framework source topic
Read the source code
Programmers work with code every day. After years of basic education and professional training, most programmers can “write” code, or at least copy and modify code. However, can read the code is not in the majority, can read the code and really understand the source code of some big projects, very few. This also leads to a lot of errors in the way source code is viewed.
Introduce the classical design ideas used in the source code in detail, see how Daniu is to write code, enhance the technical aesthetic, improve the core competitiveness.
To help you find the analysis of source code entry point, in the thought of a huge sublimation. Know what it is and why. Make your knowledge your own
High Performance Architecture Topics
How does the system architecture meet the challenge of high concurrent traffic in the Internet era? As a technology developer, how to deal with the skill crisis brought by technological change. Based on the evolution of traditional architecture to distributed architecture brought about by the technical changes.
In the depth and breadth of technology has been leaps and bounds. To become the T-type talents needed by the Internet industry
Topics on Microservices Architecture
SOA has become a standard solution for Internet companies to cope with complex business requirements changes and user expansion, and the framework related to microservices was born for this purpose.
