After I moved a domain to a new host, the original certbot certificate on the old host still included it, causing renewal errors. I explain that domains can’t be deleted from a certificate directly; instead you renew the certificate specifying only the domains you want to keep, and certbot warns about the ones being dropped.

Frustrated with slow VM provisioning in Proxmox compared to BinaryLane, I used a $200 Digital Ocean credit from a podcast promotion to test how quickly a cloud VM can be spun up. A Debian droplet booted in about 42 seconds, but initial SSH access proved awkward, requiring me to dig through docs and the web console to set up a user since Debian blocks root login.
