The Emperor Has No Clothes: How to Code Claude Code in 200 Lines of Code

Mihail Eric argues that the core functionality of complex AI coding tools like Claude Code or Cursor is not magic but rather simple agentic logic. He demonstrates that these systems can be replicated in about 200 lines of Python by focusing on the essential loop of reading files, editing code, and executing shell commands.

The Right Way to Use AI for Writing Maintainable Code

Arjan argues that long-term code maintainability with AI requires developers to act as high-level architects, constantly refining design patterns and decoupling responsibilities rather than accepting the first "working" output. The video demonstrates this iterative process by showing a real interaction with ChatGPT, where he systematically guides the AI to replace messy if-statements wit...

FastAPI Tutorials

In this series, we'll be learning how to build a full-featured web application from the ground up using the FastAPI framework in Python. We'll build both a JSON API for programmatic access and HTML pages for users to browse in the browser. Throughout the series, we'll set up a database with SQLAlchemy, create Pydantic models for data validation, and implement complete CRUD operations. We...

A field guide to sandboxes for AI

Luis Cardoso breaks down the technical differences between containers, microVMs, gVisor, and WebAssembly to help developers choose the right isolation boundary for running untrusted AI agents. He emphasizes that a secure sandbox requires a clear distinction between the isolation boundary, the access policy, and the lifecycle management of the environment to prevent malicious code from co...

Under the Hood: Universal Commerce Protocol (UCP)

Google has introduced the Universal Commerce Protocol (UCP), an open-source standard designed to enable seamless "agentic commerce" across AI platforms like Gemini and Search. The protocol eliminates integration bottlenecks by providing a unified abstraction layer for discovery and transactions, allowing AI agents to handle the entire shopping journey from product search to secure payment.

Beyond One-Size-Fits-All RAG: Why Different Knowledge Sources Need Different Retrieval Strategies

Jo Chen argues that high-performance RAG systems require specialized retrieval pipelines for different data types, such as contextual prefixes for technical manuals and whole-document summaries for blog content. The post details a multi-layered defense strategy involving hybrid search, LLM reranking, and aggressive caching to improve accuracy while managing the high costs of production AI.
