How to add LiteLLM as a proxy layer on top of Ollama and Open WebUI, unifying local and cloud AI models behind a single OpenAI-compatible endpoint, managed via GitOps with ArgoCD.

How to wire the LiteLLM gateway into aider for terminal-based AI pair programming, using model aliases, a port-forward systemd service to work around SSL issues, and the current 3B model lineup running on a GTX 1650.

The second part of the GPU homelab series: bootstrapping a full GitOps platform on k3s using ArgoCD’s app-of-apps pattern, wiring up Ollama and Open WebUI, and the four gotchas that will trip you up.

A step-by-step walkthrough of turning an old GTX 1650 laptop into a GPU-enabled single-node k3s cluster, explaining the why behind each layer of the stack and the two non-obvious gotchas that will trip you up.

A practical guide for software engineers on building production-grade RAG systems using hybrid retrieval, re-ranking, and grounding techniques to reduce hallucinations and improve answer quality.

A practical deep-dive into vector embeddings and cosine similarity — the mathematical foundation that makes retrieval in RAG systems actually work.

A practical guide for software engineers covering how vector databases use Approximate Nearest Neighbor algorithms to search millions of embeddings efficiently, and how to chunk documents intelligently so your RAG pipeline actually retrieves useful, precise context.

A practical walkthrough of adding per-page context awareness to a floating AI chat widget built with Hugo and Netlify Functions, covering layout overrides, slug injection, priority chunk labeling, and the prompt engineering fix that made summarise-this-post actually work.

A practical walkthrough of building a conversational AI assistant for a Hugo static site using TF-IDF retrieval over a flat JSON knowledge base — no vector database, no backend server, no embeddings infrastructure required.

A practical, code-illustrated guide to how TCP/IP, DNS, and modern data transmission protocols work under the hood — from handshakes and packet routing to WebSockets, gRPC, and QUIC.
