/homelab

• I enjoy tinkering with small technology projects, and I learn a ton from these experiments. I also self-host a number of apps/services from my home as well as various cloud environments. This page describes some of my technical playground.*

Everything is connected to my Tailscale [1] tailnet, with a GitOps-managed ACL to allow access as needed. This lets me access and manage systems without really caring if they're local or remote. Tailscale is magic [2].

- Cyberchef [9], the Cyber Swiss Army Knife

- Hashicorp Vault [10] for secrets management

- Miniflux [11] feed reader

- RIPE Atlas Probe [12] for measuring internet connectivity

Tailscale Golink](https://github.com/tailscale/golink), a private shortlink service ([post

• `files`: Ubuntu 20.04 file server. Serves (selected) files semi-publicly through Tailscale Funnel [13]
