I’ve made a provider to deploy Nixos hosts with Terraform.

Here is a list of features it support at this moment:

• configuration deployment
• secrets deployment
• SSH bastions
• provider, Nix, SSH settings overriding on per-host basis
• host addresses prioritization

This note is about using Emacs for collaborative editing with help of package called crdt.el.

This is a note about the integration of the Certbot with Let’s encrypt DNS–01 authentication mechanism. Will not use any cloud services (fuck cloud), just self-hosted DNS instances, like good old times. I’ll show how to configure Knot DNS to accept dynamic DNS updates from knsupdate and how to create a rudimentary hook for Certbot which will use knsupdate to set TXT records with _acme-challenge.
