As a software technician, we must first face a problem. In order to solve practical design and implementation problems, we often need a lot of knowledge as the basis, such as programming languages, platform standards, basic libraries, design patterns, corporate platform class libraries and code development specifications, and general solutions for specific problems. This is often easy to give people the illusion that all these things require me to remember all the things I have come into contact with or may use in the future, as I did at school, for work. It increases the work pressure virtually, and a large amount of free time is occupied, greatly reducing the quality of life.

Maybe we should reflect on whether more knowledge can be equivalent to stronger technical capabilities? Can more knowledge be equal to higher work efficiency? Can more knowledge pave the way for my future?The most challenging question is, do I have time to finish learning this knowledge? In the words of Lu Xun, "I have both life and life, and I have no knowledge, so I have no knowledge of life and life !"In my opinion, this sentence of the philosopher did not let me break the jar! It implies that I should consider this question from the perspective of Economics. "Since my time resources are scarce, how can we maximize the utilization efficiency of such scarce resources ?"Knowledge itself is indeed a kind of power, but should we further consider how to maximize this power?

In this article, I want to explain how I understand how to plan and manage internal knowledge, and how to train the best edge of my career.


I. Planning of the Knowledge System

Everyone has an "Internal small library", which contains all the accumulated knowledge in school, life, and work. Although the existence of the internal library is a common feature, the construction quality, construction scale, and actual utility of the library often vary from person to person. Some people's libraries are organized in disorder, and it is very laborious to find any materials. Some people do not take the initiative to build their own libraries, all of these materials are passively absorbed. the correctness of these materials is beyond the doubt that we can find the materials that are truly helpful to our daily life and work in this library in the future.

("Metaphor" is a good thing. After the internal knowledge system is compared to a library, the necessity of planning the knowledge system and how to plan it can give a clear idea from the perspective of library construction .)

The ultimate goal of incorporating knowledge into the knowledge system is to "quickly" find "useful" knowledge from the knowledge system and guide the current practice. To "Quickly search", you need to plan and optimize the organizational structure of the knowledge system. To "use", you need to consider your actual needs and the extent to which you need the knowledge. Next we will summarize the planning points of the Knowledge System from the perspectives of the organizational structure of the knowledge system and the effectiveness of the knowledge system.

1. Organizational structure of the Knowledge System

First, I need to divide the knowledge I need into several major sections, such as being a person, doing things, technology, management, and hobbies;

Each root section is further divided into several subsections. For example, the technical sections can be further subdivided into: programming basics, J2EE technology, software engineering, and so on;

And so on, until the Forum segment is further subdivided, it will be called the leaf forum;

The content of the leaf section is managed and organized by a tree. The organizational structure of the tree is related to the characteristics of the knowledge field represented by the leaf section.

From the root forum to the leaf forum, it is best to use a tree for intuitive modeling, so that you can understand your current knowledge.


2. unbalanced development of the Knowledge System

A person's life is very short, so it is impossible to learn everything. In the construction of the knowledge system, we are faced with a trade-off, which content needs to be included, and which needs to be decisively abandoned, which requires more time and simple understanding. How do we make these decisions? Based on the order of values and the ideal priority, the Knowledge modules in the knowledge system need to master the input energy, the content to be mastered, and to what extent. Because the benefits gained from a kind of knowledge input depend on the extent to which the knowledge promotes a person's close to his or her ideal.

Let's take a look at Sherlock Holmes's knowledge structure. It should be consistent with this point of view.

Scope of knowledge of Sherlock Holmes

1. literary knowledge-None

2. philosophical knowledge-None

3. astronomical knowledge-None

4. Political knowledge-superficial

5. Botany knowledge-incomplete, rich knowledge of opium and drugs, and no knowledge of gardening

6. Geology knowledge-practical but limited. At a glance, he could tell different soil quality. When he came back from a walk, he asked me to see the mud stains on his leg and based on the color and hardness of the mud stains, point out where they are splashing in London.

7. Chemistry knowledge-profound

8. anatomy knowledge-accurate, but not systematic

9. Thrilling cases-extensive knowledge. He seems familiar with all the details of every thrilling case in this century.

10. Good violin

11. He is good at using sticks, and is also good at swords and boxing.

12. Have sufficient practical knowledge about British law

Note: The article also mentions that he has no idea about contemporary literature, philosophy, and politics,I do not know that the Earth is turning around the sun.

Ii. Organization of the Knowledge System

You know what kind of knowledge you need to know and how much you need to know, and what kind of organizational knowledge you need. The next step is to discuss the specific storage of knowledge. In general, knowledge storage can be divided into two categories: internal storage and external storage. The internal storage is to store the knowledge in your mind and use it at any time. The external storage is to collect and organize the knowledge into a container other than your mind. It is used for retrieval and later use.

The attention scope and attention characteristics of the internal and external store knowledge are not the same. The following is an analysis and summary respectively.

1. Internal Storage knowledge

What knowledge needs to be stored internally?

Concepts, theories, and methods that have important guiding values for life and work.

The usage frequency is very high, and the internal storage can significantly speed up the work efficiency knowledge.

20% of core knowledge in a discipline.

What is the form of knowledge storage?

The form of Mind Map (recommended ).

The form of the image (a picture is better than a thousand words ).

How to speed up internal storage?

Thorough understanding and natural internalization

Use memory

Focus on internal storage and make full use of the potential of the brain

Qimen tips:

The faster the learning speed, the better the learning effect. Accelerate the learning speed and increase the number of times per unit time;

Self-teaching method;

Subconscious learning;

Try the recall method.

How can we keep the internal storage knowledge longer?

Optimize storage formats, such as using images as memory

Use memory, such as image and imagination

Evening review plan



2. External Store knowledge

What knowledge requires external storage?

External knowledge storage form?

How can we accelerate the retrieval of External Store Data?

Excellent tools (good tools: Support for indexing, fast search, preferably online, tree structure, and support for label)

Continuously update and optimize the knowledge structure and content (integration, deletion, and correction)

3. Knowledge that does not need to be stored

Some simple, repetitive, and temporarily valuable knowledge can be solidified into tools without wasting valuable time and energy for repetitive work. It embodies the principle that simple things are repeated and repetitive things are innovated.

Case: Automatic Code Generation Tool for addition, deletion, modification, and query of nimin


Iii. Establishment of Knowledge System

The key is two words: 'sher' and 'D '. Under the premise of limited resources, the most important thing can be grasped only when the secondary one is abandoned.

First, clarify the learning purpose and the structure of the knowledge to be learned.

Then, the formation of human body as a metaphor, in several rounds to achieve the establishment of the knowledge system.

In the 1st round, we first outline and grasp the framework architecture of knowledge, that is, the formation of a skeleton-Internal Storage

2nd rounds, master the core of 15% knowledge, that is, constructing core organs such as the heart --- internal storage

3rd rounds of exploration and summarization are used to master the 5% relational knowledge throughout the core organs and skeleton, so as to form an organic whole, that is, constructing the neural system --- internal storage

4th rounds, will be used frequently, but has little memory value knowledge, organize it into a template or external storage knowledge base, then quickly locate reference-External Storage

5th rounds of other knowledge, not as a learning goal, but can be instantly searched and quickly searched when used.


Iv. Updating the Knowledge System

As your experience increases and your experience increases, you will surely find that the current knowledge system is imperfect, the structure is unreasonable, the content is incomplete, or the importance is unbalanced. Check and reflect on the rationality of the organizational structure of the knowledge system and the content of the knowledge system every quarter or every year (based on the size of its guiding role in realizing the ideal life practice ), explore better structures and content, and constantly update the knowledge system.


V. potential value of the Knowledge System

Knowledge is not a power, but a potential power. Continuously apply learned knowledge to practice, guide practice, and accept feedback from practice. updating knowledge is the fundamental path to maximize the power of the knowledge system.
