Desk with Clean Architecture notes

Introduction

Clean Architecture is a software design philosophy that aims to create systems that are easy to understand, maintain, and test. It was introduced by Robert C. Martin (Uncle Bob) in his book “Clean Architecture: A Craftsman’s Guide to Software Structure and Design.”

Key Concepts

Independence: The architecture should be independent of frameworks, UI, database, and any external agency.
Testability: Business rules can be tested without the UI, database, web server, or any other external element.
Maintainability: The system should be easy to maintain and extend.

Layers of Clean Architecture

Entities: Core business rules and data structures.
Use Cases: Application-specific business rules.
Interface Adapters: Converters that interface with the use cases and entities.
Frameworks & Drivers: External systems like UI, database, and web frameworks.

Conclusion

Clean Architecture provides a blueprint for building maintainable, testable, and scalable software systems. It promotes separation of concerns and decoupling of components, making the system easier to manage and evolve.

Reducing Latency in LLM: How Prompt Caching Can Optimize Performance

Prompt caching is a powerful technique for reducing latency in conversational AI systems. By caching static parts of prompts, such as token embeddings and intermediate states, systems can significantly speed up response times.
