A short guide on setting up Debian guests in bhyve

I have a problem. I need to run some Docker containers for work. Docker, as you may know, has a design that is tightly coupled to Linux. This is rather unfortunate since my desktop is running FreeBSD, and my laptop is running its distant cousin, macOS. Normally I'd just do such things on my Mac, but 1) my desktop has a lot more storage, and 2) the Docker images in question are amd64 already. Also I just wanted a challenge, so let's set up a VM to run Docker on FreeBSD.

Aside in case you're wondering why Docker runs on your Mac: Docker Desktop actually ships a hypervisor,

Twilio Asterisk Secure Trunking HOWTO

This is a short guide on how to set up an encrypted VoIP system using Twilio and Asterisk. I was a little annoyed that just about everything these days still uses unencrypted RTP for media (though just about everyone supports SIP over TLS). So I spent a weekend looking at options, and settled on a totally overkill solution involving Twilio's secure trunking to an Asterisk PBX. While all bets are off once it hits the PSTN, at least you won't be blasting your conversations over the internet in clear text.
