Okay, I understand. I will translate the provided document into English, ensuring that all code blocks and formatting remain unchanged. Here's the plan: 1. Read the entire content of the provided document. 2. Translate the Chinese text into English. 3. Output the English translation, preserving all formatting and code blocks. Since the document content is already provided in the prompt, I can proceed directly to the translation and output step. I apologize for the error in the previous turn. I incorrectly tried to call `write_file` as a tool. I have already completed the translation internally. Here is the English translation of the document, maintaining all the original formatting: # ๐Ÿงญ The Way of Programming > Absolute source of benefit, ten times the master. Three returns day and night, ten thousand times the master. A highly condensed draft on the essence, abstraction, principles, and philosophy of programming. It is not a tutorial, but the "Tao": the structure of thought. --- # 1. Program Ontology: What is a Program? - Program = Data + Function - Data is fact; Function is intent - Input โ†’ Process โ†’ Output - State determines the form of the world, transformation depicts the process - A program is a description of reality, and also a tool to change reality **In one sentence: A program is structured thought.** --- # 2. Three Core Elements: Data ยท Function ยท Abstraction ## Data - Data is "existence" - Data structure is the structure of thought - If data is clear, the program follows naturally ## Function - Function is "change" - Process is cause and effect - Logic should be transformation, not manipulation ## Abstraction - Abstraction is retaining the essence while discarding the extraneous - Abstraction is not simplification, but extraction of essence - Hiding the unnecessary, exposing the necessary --- # 3. Paradigm Evolution: From Doing to Purpose ## Procedural Programming - The world is composed of "steps" - Process-driven - Control flow is king ## Object-Oriented Programming - The world is composed of "things" - State + Behavior - Encapsulates complexity ## Purpose-Oriented Programming - The world is composed of "intent" - Speaks of requirements, not steps - From imperative โ†’ declarative โ†’ intentional --- # 4. Design Principles: Rules for Maintaining Order ## High Cohesion - Related things close together - Unrelated things isolated - Single Responsibility is the core of cohesion ## Low Coupling - Modules like planets: predictable, yet unbound - Fewer dependencies, longer life - No coupling, only freedom --- # 5. System View: Viewing Programs as Systems ## State - The root of all errors, improper state - Less state, more stable program - Make state explicit, limit state, automatically manage state ## Transformation - A program is not an operation, but a continuous change - Every system can be seen as: `output = transform(input)` ## Composability - Small units โ†’ composable - Composable โ†’ reusable - Reusable โ†’ evolvable --- # 6. Ways of Thinking: The Programmer's Mindset ## Declarative vs Imperative - Imperative: Tell the system how to do it - Declarative: Tell the system what you want - High-level code should be declarative - Low-level code can be imperative ## Specification Precedes Implementation - Behavior precedes structure - Structure precedes code - A program is the shadow of its specification --- # 7. Stability and Evolution: Making Programs Live Longer ## Stable Interface, Unstable Implementation - API is a contract - Implementation is detail - Not breaking the contract is being responsible ## Complexity Conservation - Complexity does not disappear, it only shifts - Either you bear it, or the user bears it - Good design converges complexity internally --- # 8. Laws of Complex Systems: How to Manage Complexity ## Local Simplicity, Global Complexity - Each module should be simple - Complexity comes from combination, not modules ## Hidden Dependencies are the Most Dangerous - Explicit > Implicit - Transparent > Elegant - Implicit dependencies are the beginning of decay --- # 9. Reasonability - Predictability is more important than performance - Programs should be understandable by the human mind - Few variables, shallow branches, clear state, flat logic - Reasonability = Maintainability --- # 10. Time Perspective - A program is not a spatial structure, but a temporal structure - Each piece of logic is an event unfolding over time - Design should answer three questions: 1. Who holds the state? 2. When does the state change? 3. Who triggers the change? --- # 11. Interface Philosophy ## API is a Language - Language shapes thought - Good interfaces prevent misuse - Perfect interfaces make misuse impossible ## Backward Compatibility is a Responsibility - Breaking an interface = breaking trust --- # 12. Errors and Invariants ## Errors are Normal - Default to error - Correctness needs proof ## Invariants Keep the World Stable - Invariants are the physical laws of a program - Explicit constraints = creating order --- # 13. Evolvability - Software is not a statue, but an ecosystem - Good design is not optimal, but adaptable - The best code is the code you will understand in the future --- # 14. Tools and Efficiency ## Tools Amplify Habits - Good habits are amplified into efficiency - Bad habits are amplified into disaster ## Use Tools, Don't Be Used By Them - Understanding "why" is more important than "how" --- # 15. Mental Models - Models determine understanding - Understanding determines code - The right model is more important than the right code Typical models: - Program = Data Flow - UI = State Machine - Backend = Event-Driven System - Business Logic = Invariant System --- # 16. Principle of Least Astonishment - Good code should work like common sense - No astonishment is the best user experience - Predictability = Trust --- # 17. High-Frequency Abstractions: Higher-Order Programming Philosophy ## Program as Knowledge - Code is the precise expression of knowledge - Programming is formalizing vague knowledge ## Program as Simulation - All software is a simulation of reality - The closer the simulation is to the essence, the simpler the system ## Program as Language - The essence of programming is language design - All programming is DSL design ## Program as Constraint - Constraints shape structure - Constraints are more important than freedom ## Program as Decision - Every line of code is a decision - Delaying decisions = retaining flexibility --- # 18. Quotations - Data is fact, function is intent - A program is cause and effect - Abstraction is compressing the world - Less state, clearer world - Interface is contract, implementation is detail - Composition over inheritance - A program is a temporal structure - Invariants make logic stable - Reasonability over performance - Constraints create order - Code is the shape of knowledge - Stable interface, fluid implementation - No astonishment is the highest design - Simplicity is the ultimate complexity --- # Conclusion **The Way of Programming is not about how to write code, but how to understand the world.** Code is the shape of thought. A program is another language for understanding the world. May you maintain clarity in a complex world, and see the essence in code.
