Many of them needed to manage more (e.g. SMTP credentials for email notifications). Because I’ve always been paranoid about security, I stored most of those secrets in Ansible Vault, the password for which is stored in only one location — my memory. Therefore, each time I ran any of those playbooks, I’d have to enter two passwords interactively: the sudo password and the Ansible Vault password.

This $120 HDMI Gadget Can Turn Any Smart TV Into A PC

You can already use your smart TV to watch content from major streaming services, play AAA gaming titles on cloud gaming services, or listen to music or podcasts without attaching any extra devices. Now, thanks to a new HDMI gadget the size of a regular streaming stick, you can also add full PC capabilities to your TV. A US-based mini PC maker, Azulle, offers a mini PC in a stick-style form factor that attaches directly to an HDMI port on your TV and brings a full-fledged desktop operating system in the form of Ubuntu.
