FEMS Project #3 — Streamlit Comparison Dashboard + 3-Backend Question Evaluation (Claude 9 / exaone 7 / gpt 7)
Put a Streamlit dashboard on top of FEMS RAG and threw the same question at 3 backends (exaone3.5:7.8b / claude-opus-4-8 / gpt-4o) simultaneously to compare. Q1 (air compressor anomaly in May) — exaone and gpt said 'no data', while Claude inferred 'weekend-hours anomaly' from summary stats alone without raw data + disclosed its limitations. Q2 (savings measures from a manager's perspective) — Claude 9/10 (incomplete due to token truncation), exaone 7/10 (broken index), gpt 7/10 (concise but hallucinated 'capacitor'). Results of 5-axis scoring.

FEMS Project #1 — Comparing Low-Spec Local Setup (Ollama + bge-m3 + Chroma) vs Claude API RAG
Building a RAG prototype while studying the FEMS (Factory Energy Management System) domain. Comparing local LLM inference (Ollama) on a low-spec environment (GTX1660 Super, 6GB VRAM) against calling the Claude / OpenAI APIs. Using bge-m3 for embeddings (strong Korean support) and Chroma as the vector DB. Ollama's cold start of 95 seconds dropped to 10 seconds after warm-up, with accuracy matching the cloud.

The Day Claude Code Suddenly Stopped Working — the 529 Overloaded Error and the Existence of status.claude.com
I turned on Claude Code in the morning as usual, but agent calls kept failing with a 'server overloaded' error. A short troubleshooting log tracking down the cause through API Docs, a developer group chat, and status.claude.com — turned out to be a temporary overload on Anthropic's server side.

Building a RAG Q&A System with Chroma + My Blog — From Parts to System
Yesterday I played with the parts of RAG (embedding / cosine similarity / chunks). Today, I put them together into a system. I introduced the Chroma vector DB, indexed 270 chunks from my blog, and built a Q&A system with OpenAI + Claude. The most memorable moment was when it answered 'I don't know' to a question about information not covered on my blog.
