About Me
Technology and business in the AI age, taken apart on the timescale of geology. What I Write # This blog focuses on rigorous deep thinking and software engineering, rejecting buzzword inflation and surface-level summaries: 1. AI Fundamentals & System Implementation # Complete Guide to RAG Systems: Building a production-grade local Retrieval-Augmented Generation system with LangChain, Ollama, and pgvector. Glossary of 270+ AI Terms: Systematic taxonomy spanning tokens, embeddings, Transformers, and prompt engineering. GPU Accelerated Training & CUDA: Memory allocation patterns, hardware accelerators, and parallel training topologies. 2. AI Agent Architecture & Source Dives # Claude Code Source Dive: The Think-Act-Observe Loop: Deconstructing industrial Agent design — how a single closed loop powers complex tool use and reflection. Agent Memory Architectures: Workspace context persistence, session compaction, and progressive disclosure protocols. Multi-Agent Engineering: Dynamic intervention, runtime boundaries, and agentic orchestration. 3. Current Affairs & Global Economics # The Economist Readings: Structural analysis of geopolitics, semiconductor sovereignty, and macro trends. Twilight of the County Town: Micro-level investigation of industrial relocation, real estate, and social shifts. 4. Engineering Practice # Tmux Practical Guide: The essential command set for persistent terminal multiplexing and splits. Distributed Heartbeat Systems: Failure detection, leases, and partition tolerance. About ByF # ByF and BaiFan (白帆) are two spellings of the same name.
