Plan an advanced route and confirm your own stage
Every programmer should plan his own learning route when he improves himself, and he should master different levels of professional skills at different stages.
I divided the learning stages of programmers as follows:
- The first stage: Junior programmers, everyone basically has zero foundation, or understands some basic knowledge.
The most important thing at this stage is to lay a solid foundation and be familiar with algorithms and data structures. Most of the code may be copied from others, which is rather confusing, and there will be some deficiencies in quality.
Suggestion: master the company's technology, learn more about industry news, the current situation of the industry, and plan your own direction.
- The second stage: Intermediate and senior programmers can make the code more reasonable and standardized, more elegant than before, and can avoid some classic errors.
This stage is precisely the stage where professional development planning needs to be systematically carried out. You can choose to go to a higher company platform. You can already do many practical projects. Therefore, this stage is very important for the career development of most programmers.
In the process of advanced development, there is a point that cannot be avoided, that is, "high concurrency." Many programmers have stopped because they have not been exposed to high concurrency and lack practical experience, and finally terminated the programmer's career.
Suggestion: Carry out high-concurrency microservice project exercises in advance. Because some companies are not large enough in the company and their business does not involve high concurrency, we can choose to simulate and create high-concurrency scenarios for actual combat exercises.
- The third stage: top programmers. By this stage, they are already very good engineers in the field of programmers, and they can become full-stack engineers or software designers.
Programmers at this stage are already big names in the industry, proficient in multi-field technical frameworks, and their income is considerable. Basically, the annual salary is 40w. You can choose to be promoted to management, become CTO, and lead the team; you can also choose to continue to study in technology and become a great god in the field.
Suggestion: technology + management to walk on two legs, just like now you are convinced that a technology is not as good as your leader?
Cheats sharing
This is a note sent to me by the head of the department after I joined Ali. The boss said that this is a summary of the P9 boss’s hard work over the past ten years. With it, I went step by step from an intern to the current P7 post. I also helped my friends get 7 offers. Now Share with everyone to learn together, I hope to help you in the golden three and silver four o'clock;
The general contents of the notes include: Java collection, JVM, multithreading, concurrent programming, design patterns, Spring family bucket, Java, MyBatis, ZooKeeper, Dubbo, Elasticsearch, Memcached, MongoDB, Redis, MySQL, RabbitMQ, Kafka, Linux, Netty, Tomcat and other big companies interview questions, etc., wait for the technology stack!
And it also cooperates with various mind maps to help everyone learn and understand!
Since there are too many details, only some of the knowledge points are screenshots for a rough introduction, and each small node has more detailed content! If there is need this Ali notes P9 friends can [see below] Add small helper to get to
JVM：
JAVA collection:
JAVA multi-threaded concurrency:
Spring principle:
Kafka：
RabbitMQ：
Encryption Algorithm:
YRAM ：
Write at the end
The content of this note is too large, even if there is a lot of cutting a picture for a knowledge point, just show this point first, if you want to improve the system, your friends can get a copy for free and learn slowly;
