Woot. The diff to disable SMT (aka Hyperthreading) just landed in -current.

You can now disable SMT via a sysctl. The default is disabled.

I'd *love* to see more non-usual-suspects give talks at *BSD conferences.

Sure, the usual-suspects do stuff, but SO DO YOU! And we don't already know what you do!

And of course, you *are* cool enough to do this.

#EuroBSDCon presentation deadline is coming up on Sunday! Do you do cool stuff with #OpenBSD, #FreeBSD, #NetBSD (or any #BSD)? PS, yes you do. You should submit an abstract for a 45 minute presentation, and give a talk.

Travel, hotel, and entry will be covered for selected speakers!
