I have a few excited #guix related things on the go:

1. Need to finalize and publish a post-mortem following the outage of cuirass.genenetwork.org
2. (and most exciting): I have a proof-of-concept implementation of a secrets management system for guix. Unlike #sops-guix, this system stores no secrets in configuration, only secret metadata (name, and how to decrypt it at runtime). It configures shepherd services to mount a tmpfs, decrypt secrets (and also populate dotenv files). Stay tuned!
