Quick possible answer - since find_fit uses Scipy, perhaps we aren't

I assume that it's not possible to have Sage start with just the one click
from a pre-installed VM, a
t a little lab
admin wizardry could make the VirtualBox solution nearly like having other
programs to double-click. Maybe there could even be a script that opened
the VirtualBox with Sage at exactly 9:55 for a 10:00 class...

I'm having trouble on Mac (FF and Safari) getting the graph_editor() to
work. It loads, but clicking does not create points. Any ideas? Maybe I
did something wrong.
I didn't see a Trac ticket about this.
http://trac.sagemath.org/sage_trac/ticket/8222 seems unrelated, and indeed
untouched
Just to clarify, Ivan means that at the top of the worksheet you could do
%auto
gap._eval_using_file_cutoff = 1000
Of course, you'd have to be in "sage" evaluation mode to do this, not
"gap". This might be a good workaround.
Another possible workaround might also be to just indent less, though

How hard would it be for someone to bdist an app and non-app dmg of Sage
5.0 for Intel Core Duo and then just make sure the download page makes this
clear? This would be a good stopgap solution. Presumably others might
download it and then just decide not to bother getting it once it causes
Could this also be part of the SAGE_FAT_BINARY problem with MPIR? Very
naive question.

There is the "stopgap" terminology, but that's not what we called the
