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!

Self-Hosted AI: Qwen 3.8 on a Rented Blackwell at 150 Tokens per Second

An open-weight Qwen 3.8 27B model, an RTX PRO 6000 Blackwell rented by the hour, and one shell command to start it. For most of my everyday coding it is good enough, it answers at roughly 150 tokens per second, and my prompts stay on infrastructure I chose. Some honest caveats about what “self-hosted” means on someone else’s GPU are included, along with the workflow that has worked best for me: a frontier model for architecture, and a fast open-weight model for the token-heavy implementation loop.
