How to learn more efficiently?
Many novice programmers can't find a direction in learning at first, but I think that after a period of novice, most of these problems will become less obvious and the direction of work will gradually become clear.
But it didn’t take long for the information I could learn to surpass my ability to learn every day, such as buying books I didn’t read, collecting posts I didn’t read, and marking articles I didn’t pay attention to anymore, let alone. Faced with various technology sharing or new things in Weibo every day.
Most people have a limited amount of time left for their own learning every day. How to improve learning efficiency at this stage has become the focus of the solution.
Talking about my experience in improving learning efficiency is actually very simple: systematic learning.
I used to like to read some blogs or articles that "looked" relatively easy to understand. I would mark any technical articles on Weibo and WeChat every day, and basically read them in a few minutes. But after a period of time, although I have read a lot of things, I still have a state of spinning around, and I haven't felt any actual improvement.
In the end, I couldn't help but gnawed through the thick book, and suddenly I felt a sense of relief: what I learned when I was studying was a complete knowledge network, and each knowledge point was connected and distinguished from other content. This kind of comprehensive understanding is higher than that of an independent article.
After reading the book for a period of time, the knowledge that is not originally in the same system will gradually be connected. For example, the development of back-end services. Simply sort out, it becomes like this:

After repeating the painful learning and combing process several times, reading some independent articles or materials will often get twice the result with half the effort, because you can find the corresponding knowledge in the system, and sometimes you only need to read one sentence per page in a book. If you tap that layer of window paper, you can master new knowledge.
Learning experience of architecture development technology road
One, read the source code
Reading and analyzing source code is the most basic code ability of programmers, and it is also the root of code farmers. Learning the classic design ideas and common design patterns used in classic source code can help you understand how Daniel writes code, so as to absorb Niu's code skills. In Alibaba interviews, the underlying principles of frameworks such as MyBatis and Spring are often asked

Two, distributed architecture
Alibaba has many large teams. There are many small teams in this large team. After the small teams, they do different businesses. If you want to become a universal player among the first-line Internet companies, there are many in the most mainstream distributed architecture. Knowledge must be understood and learned. And during the Alibaba interview process, the interviewer will ask questions about actual application scenarios: such as microservices, user volume, concurrency, business complexity, and scalability, etc. I won't go into details here. This dick provides a learning idea of a distributed architecture and is also a system that I am currently learning:

Three, microservice architecture
Microservices is one of the hottest topics in Internet architecture technology, and it is also the direction that Bendi is currently studying and researching. During the Alibaba interview process, interviewers rarely ask questions about microservices. But as a developer, a programmer with technical dreams, the microservice architecture is the mainstream technology that must be understood now. The editor has developed a microservice technology learning plan for himself:

Four, concurrent programming
Concurrent programming is almost all Internet company interview questions. Concurrent programming is one of the most important skills for Java programmers and one of the most difficult skills to master. It requires programmers to have a deep understanding of the operating principles of the lowest level of the computer, and at the same time requires programmers to have clear logic and careful thinking, so that they can write efficient, safe and reliable multi-threaded concurrent programs. At present, there is no systematic and comprehensive study syllabus for concurrent programming on the Internet. I have collected a lot of information and summed up a most comprehensive study syllabus:

Five, performance optimization
Performance has always been a headache for programmers. When the system architecture becomes complex and large, the performance will decline. Especially the first-line Internet companies like Alibaba pay the most attention. Therefore, if you want to enter Alibaba, performance optimization must be a part of in-depth learning and understanding. Although the performance optimization is not an expert, you can confidently say that you are proficient (note: you must not write proficient xxxx on your resume, or the interviewer will stun you. Fortunately, this dick is still confident)

6. Design patterns
Design pattern (Design pattern) is a set of code design experience that has been used repeatedly and is known to most people. The use of design patterns is to reusable code, make it easier for others to understand, and ensure code reliability. There is no doubt that design patterns are win-win for others and the system. Design patterns make code preparation truly engineering. Design patterns are the cornerstone of software engineering, just like the bricks of a building. The reasonable use of design patterns in the project can perfectly solve many problems. Each pattern has a corresponding principle to correspond to it. Each pattern describes a problem that recurs around us and the core of the problem. Solution, which is why it can be widely used.

A developer must have a weapon that suits him, that is, he must first sharpen his weapon if he wants to do his job well. Whether it is a novice or an experienced developer, he must first choose a good tool. The following are my commonly used development tools:
Maven, project management
Jenkins, continuous integration
Sonar, code quality management
Git, version management
How to study together, is there any information that can be used for free?
The above is a graph of Java architecture technology collected and summarized by myself. Because I prefer technology, I have collected some architecture technology materials such as Java high concurrency, distributed, JVM, spring, source code analysis and kafka. If you are interested in the materials, you can pay attention to the end of the article. The public account obtains these materials, and everyone is welcome to discuss and learn.

Information collection method: This is only a part, I will not post all of them. This set of interview questions has given me a lot of help for this interview. Now share it with everyone! You can follow the official account below to receive it.
