  1. Spinning Down SAS Disks

    SAS drives ignore ATA standby and the usual tools quietly stop working on them. What actually parks them, and a script that keeps them parked.

  2. Offsite Backup to Oracle Cloud with restic

    An encrypted offsite backup on an Oracle Cloud Always Free instance, no dependencies — in place of a HyperBackup setup that needed a working DSM to restore.

  3. One Identity Provider for Everything

    Authentik on Oracle Cloud in place of scattered logins: Google login everywhere, proxy auth for Guacamole, OAuth2 for Portainer, a K8s outpost for the cluster.
