Hi,
yesterday on IRC I realized I don't understand these terms. :)
x + x -> 2*x is this evaluation?
x +y, vs. y+x ... is this canonicalization?
Is this how everyone understands these terms? If so, we need to fix
SymPy all over. :)
Also I was mistaking canonize and canonicalize:

On the other hand, using a leading zero to indicate octal is a fairly
standard convention in computer science. And it's nice to minimize
these kinds of differences between Python ints and Sage Integers.

I know, but my "picture" is a high-school teacher explaining that
leading zeros don't matter, and when someone tries it in sage, it
suddenly matters. So, imho, there is so

Any opinions about what
sage: F9. = GF(9); F81. = GF(81); F81(a)
should return? There is no canonical answer, so it may be better to
throw an exception rather than pick one of the two correct answers.
But any of these would be better than the current behavior, which is
to return 0.

Hi
When entering integers beginning with zeros in Sage, they are
interpreted octal. I'm aware of #2863 which documents the behaviour of
Integer, but that's still somewhat inconsistent when parsing strings
and annoys me a bit.
sage: int('070')
70
sage: int(070)
56
sage: Integer('070')
56

The Joint Meetings are themselves fairly early (Jan 5-8). Does "fairly
early in January" mean before or after that? Before might be awkward
because of the New Year's holiday.

AFAIK, there is no word yet
Hi Bernard, etc.:
I have a couple of questions about Giac/XCas and also you. They are all over
the map. Answer what you want and ignore the other questions.
1. Is this the public svn development server for Giac/Xcas?
http://xcas.svn.sourceforge.net/viewvc/xcas/
2. Is this the only mailing
