Lab Notes

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.

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.

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.

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.

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.

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.

First post from the BytesNation lab. What this space is about, what to expect, and why I build in the open.

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.
