The program for this convention was very slim pickings anyway... Netflix is the only big company presenting (of course). I'm saddened how cloud providers have given no love to BSD.
For me, I like understanding what's going on under the hood. OS's like FreeBSD are very straightforward. When I use even a carrier-grade Linux distro, I'm more detached to the internals and entrusting my setup more to some other party. You lose compatibility for more stability.
