Mastodon

Welcome to Larvitz Blog! I’m Christian, a Senior Consultant by day and FreeBSD enthusiast by night, with over 20 years in enterprise IT. Here I write about FreeBSD jails, PF firewalling, self-hosting, Linux system administration, and anything that’s cleanly engineered. Most articles are hands-on guides born from running my own infrastructure, from dual-stack networking and Ansible automation to hosting a Mastodon instance on FreeBSD.

Have a question or want to discuss something? Find me on the Fediverse at @Larvitz@burningboard.net. I’m always happy to chat!

Crawlfest: Building a Terminal Roguelike in Rust

For a few months now I have been building a terminal roguelike in Rust in the spirit of ADOM and NetHack. This article is about the technical groundwork: why ratatui and legion instead of a game engine, how the four map generators work (rooms, cellular-automata caverns, hand-drawn prefabs, and a hybrid of the last two), how field of view and A* pathfinding hook into my own map type through two traits, how content lives in RON files instead of code, and how save games avoid serialising the ECS at all.
