More and more hot software development technology with demand saturation, the market has become rolled up, want to stand out in many competitors, to learn how to leave to improve their own?
1. Solid programming foundation. This first means that you are familiar with the C++ language, know the features of different versions of the language (such as the differences between C++11 and the new C++20), and have a basic understanding of common language mechanisms (such as polymorphism, virtual function tables, templates, etc.).
Although it doesn’t matter what language you use, at least you have to be more skilled in using a language. How to be proficient, probably C++ underlying mechanism, multi-threaded programming, cross-platform programming you need to understand it.
In addition, the literacy of programming ability is also reflected in the understanding of algorithm ideas and data structures. After all, programs are based on algorithms and data structures. So some basic data structures, such as linked lists, arrays, binary trees, queues and so on, as well as some basic algorithm ideas, such as greedy, divide and conquer, dynamic programming, etc., are best to master.
2. Systematic theoretical knowledge. This is the division of the division and non division of the more obvious gap. In fact, many students of non-technical classes have strong programming ability, but because they have not received systematic theoretical learning, they will suffer a disadvantage in theoretical learning. Back-end development involves a lot of things, from network to performance to architecture, all need the computer theory of the system to support.
So if you have never read computer networks, operating systems, principles of computer composition, and principles of compilation, you need to buy some books.
3. Back-end foundation. If you want to do backend development, you have to at least know what the backend is. This means you need to know some basic software engineering, software architecture, design patterns, etc. At the same time, do a back-end which can not understand the database, then you have to learn some basic operations such as MySQL, Redis database?
Of course, this is probably an entry level. When it comes to back-end development, learning related concepts and technologies like microservices and middleware (Kafka/Zookeeper/Hadoop, etc.) should also be put on the agenda.
Of course, for the school enrollment, because it is really lack of large-scale online project experience, so the requirements for back-end foundation are not too high, more depends on programming ability and computer theoretical basis. However, if you are already working and want to change careers, the back-end foundation will be more important.
In my opinion, the three points are more important for Internet companies at present, so we can reflect on whether we have such ability. If you haven’t, take the time to prepare.
