I'm assuming this would also have no effect on single-processor
machines, even if one were to be silly and set MAKE=make -j2 or
something?

Things like errors in zlib... "This may not be fatal", then "read jobs
pipe, Operation not supported, stop".
Not a big deal, because with unset make but parallel spkg build there
is no problem. But just something to watch for, maybe to add to the
devel guide when
ot of interest those with the power to make it happen will concur :)

The base is the *second* argument.
sage: 1./0
+infinity
sage: CC(1)/0
NaN - NaN*I
And why -, not +, NaN*I? Since
sage: CC(-1)/0
NaN - NaN*I
sage: CC(0)/CC(0)
NaN - NaN*I
Anyone who knows more about this is welcome to say more/correct,
though!

Also it's worth pointing out that there are (at least) two contributed
papers about using Sage.

Everyone, please make this more accurate (e.g., sign up!) and think
about how to make the table even more awesome this year.

Great... more to carry. So I may have to drive that first day, and
parking in the Back Bay/Fenway is nuts. :(
