## Home Lab

Networks, hypervisors, operating systems and the machines that run them.

- [Moving from Homebrew to NixOS](https://mattoddie.dev/homelab/homebrew-to-nixos.md): How to move from Homebrew to NixOS: turn a Brewfile into a flake, map packages, replace brew services with systemd and give each project its own dev shell. (2026-10-07)
- [Setting up a lab network with UniFi](https://mattoddie.dev/homelab/unifi-lab-network.md): Set up a UniFi lab network: a separate VLAN for lab machines, switch port settings for access and trunk ports, and a firewall zone that keeps it isolated. (2026-10-05)

## AI

Building with language models: MCP servers, tools and the plumbing around them.

- [How to build an MCP server](https://mattoddie.dev/ai/building-an-mcp-server.md): Build an MCP server in TypeScript, from a one-tool example to patterns that scale to hundreds of tools: API clients, opt-in writes, trimmed output and toolsets. (2026-10-09)
