@egreg: this is a very funny moment from a game between Palmeiras and Linense in the 2013 SP Cup. The narrator saw a bird attacking a moth and decided it was worth of narrating the episode!
@PauloCereda Apropos bird: is your green bird :-) expl3 only or LaTeX3 only? And, is it free to use in a LaTeX context or restricted to be a logo of only the LaTeX project?
@PauloCereda Ah, was made for expl3 originally, now I see in a LaTeX news PDF (no hit in html when I g** custom searched on the l-p site)

I've just got a new computer which is running Sierra. I'm very confused about the Energy Saver which now has removed separate Sleep vs. Display Sleep sliders. Is there still a way to control them independently?
@DavidCarlisle -- yes, i'm hoping for stackexchange to do something globally -- but i'm not sure you routed out all the problems. the dedoubling also happened after \notag followed directly by the \\ .
@DavidCarlisle -- i'll probably be off-line for about a half hour. my workstation is acting unstable, and i have to shut it down and reboot. that's a (too) long process.
