How to Learn Programming Systematically--

I have been thinking about the essence of programming for years. Here is some analysis at different levels:

Classification by process
- What do you want to do
  - Clearly define what you want to do
  - Knowing your own purpose is what matters most
- Breaking down and recombining how events unfold
  - Break down what you do
  - Know every step clearly
  - Put the steps together
  - Do things in the most efficient way
- A dialogue with the computer
  - You must understand what a computer can do
  - You must be able to speak the computer’s language
  - You must know how to organize your words
Traditional classification
- Data structures
  - How data is organized
- Algorithms
  - The process of data flowing

A. Practice first

Programming is highly hands-on
Results come back quickly as feedback
Write a decent amount of code before anything else B. Master one thing
Go deep on one language first
Get proficient with one toolchain
Study specialized domains as needed C. Learn in layers
Level up step by step from your current level
1. Copy programs to get them running
2. Build simple programs on your own
3. Develop complete systems collaboratively
4. Build high-performance systems
As your ability grows at each stage, go deeper into the following areas
1. Programming languages
2. Operating systems
3. Networking
4. Domain specifics
