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:

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.

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.

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.

Tmux Practical Guide: The essential command set for persistent terminal multiplexing and splits.
Distributed Heartbeat Systems: Failure detection, leases, and partition tolerance.

ByF and BaiFan (白帆) are two spellings of the same name. Backend & AI systems engineer, author of the byf terminal AI coding agent and the dev-skills engineering skill set. The canonical home of this digital identity is baifan.site; technical writing lives at blog.baifan.site.

Once a reader of Earth’s deep history, now a builder of digital systems.

The Deep-Time Perspective: Geology taught me to evaluate evolution in large epochs — maintaining restraint and clarity amid technological frenzy.
First-Principles Engineering: Backend systems and distributed infrastructure are my craft. Understanding fundamental contracts and true runtime costs is the rule.
A Gentle Cynicism: Seeing technical reality and system constraints clearly, without bitter nihilism or hollow cheerleading.
