AI Programming

Redis founder antirez used Claude Code to implement a complete Z80 emulator in 30 minutes, passing the ZEXALL full instruction test. He designed a strict clean-room experiment: first had AI organize documentation, then cut off the network and implemented from scratch. Result: 1200 lines of code, zero bugs, and顺便 also built ZX Spectrum and CP/M environments.

A practical RAG tutorial: build an enterprise knowledge base Q&A system in 4 steps using embedding vector search and Claude. Contextual Retrieval cuts retrieval failure from 5.7% to 1.9%, with full Python code and Voyage AI model comparison.

Claude can’t do math or query databases on its own. But you can teach it to ‘make phone calls’ — give it the numbers for calculators, databases, and other tools, and let it dial when needed.

Writing requires revision, and so do AI responses. Learn how to use prompt chaining to make Claude self-review and improve, dramatically boosting response accuracy. Like having AI write a draft, check it, polish it, and hand you a perfect final answer.

Anthropic’s official tutorial chapter 2: Why does Claude keep missing the point? Because your prompts aren’t clear enough. Learn this one trick to make AI understand you precisely.

Claude Code 2.0.74 now has native LSP support—it can jump to definitions and find references just like VS Code, no more blind grep searches
