This is a legitimately related impromptu talk gave at BSDCan last week.

Better quality video should surface eventually..

Don’t know why you’re being voted down. Thread and video are pertinent, language is not the commenter’s fault. Here’s my token upvote.

The technical speculation begins at 7:53 in the referenced video [so, https://www.youtube.com/watch?v=UaQpvXSa4X8&t=473]

It's worth noting that TdR is not the bringer of profanity in the video.

I wasn't impressed by whoever dropped the f-bomb.

Seems to be Warner Losh[1], previously one of the FreeBSD core team members[2].

I was in the room at the time. Warner had the initial outburst. There is a second speaker, and you can hear the voice change, responsible for the profanity. Warner's delivery was much scarier in person though.
