Lab Notes
Build logs, experiments, and field notes from the lab.
Stanford Just Dropped AI's Report Card. The Numbers Do Not Care About Your Feelings.
The 2026 AI Index is out. AI data centers draw enough power to run New York. Entry-level dev hiring is down 20%. Benchmarks are broken. Investment hit $581 billion. Here is what matters and what to do about it.
10 Tools. One Brain. The Stack That Actually Builds Things.
These are not ten separate things to learn. They are ten modules in one brain. Claude Code is the nervous system. Everything else is an organ. You start with Obsidian. The rest reveals itself.
Your Homelab Has a Brain Now. Here Is How to Wire It.
Your AI forgets everything between sessions. MCP fixes that. Here is how to wire Claude into your Obsidian vault, running on your own Proxmox hardware, with n8n handling the automation.
Prompt Engineering Is Not Magic. It Is Instruction Writing.
You learned how tokens and context windows work. Now learn how to exploit them. Prompt engineering is not a mystical art. It is structured communication with a machine that follows instructions literally. Here is the field manual, sourced from Anthropic, OpenAI, and Google.
How AI Actually Works: Tokens, Context Windows, and Why Your Chatbot Forgets Things
How LLMs actually work: tokens, transformers, context windows, attention, and output sampling. Plus proven techniques to optimize token usage in Claude and ChatGPT. Interactive demos included.
MCP Hit 97 Million Installs. The Protocol War Is Over.
Anthropic's Model Context Protocol crossed 97 million monthly SDK downloads. Every major AI provider supports it. The Linux Foundation just took it under open governance. This is the standard now.
AI Agents Are Already Making Decisions for You. Here Is What That Means.
Agentic AI is not coming. It is here. It is approving loans, triaging your support tickets, and running attack campaigns. If you do not understand how it works, you are already behind.
Obsidian as a Knowledge Vault: The Field Manual
Most people use Obsidian like a glorified notepad. Here is how to build it into a real knowledge management system with structure, automation, a daily operating rhythm, and an LLM-maintained wiki that scales.
Building a Proxmox Cluster on Beelink Mini PCs
Rack servers are loud, hot, and expensive. Two Beelink mini PCs running Proxmox VE give you a proper virtualization cluster for a fraction of the cost. Here is the full build.
Claude Code Hooks: The Field Manual You Actually Need
A no-BS field manual for Claude Code hooks. What they are, when to use them, how to configure them, and practical cases that actually matter. Written for engineers who build, not tourists who browse.
Welcome to the Lab
First post from the BytesNation lab. What this space is about, what to expect, and why I build in the open.
Understanding Network Firewalls and Web Application Firewalls (WAF)
Explore the differences and synergies between Network Firewalls and Web Application Firewalls (WAF), their operational layers, scope of protection, and when to deploy them for optimal security.
