So I planned to build a new copy of 4.8 and then try out -upgrade to
get beta11... but I couldn't build 4.8!! I got the following after
the build:
Testing that Sage starts...

Dear all.
Now we are planning a Sage workshop in Japan on May 26--27.
The workshop includes a tutorial, demonstration and so on.
The main purpose of the workshop is
to increase the number of Japanese users and/or developers of Sage.
All of talks will be in Japanese.
We want to call the workshop S

I don't see the problem. What's the harm with the easy solution?

Hi,
Here's one:
sage: K. = NumberField(x-2/3)
sage: K.is_prime_field()
False
The code is just a bit too naive:
Source:
def is_prime_field(self):
r"""
Return True if this ring is one of the prime fields `\QQ` or `
\GF{p}`.
...
"""
return False

Hi Alex,
This is a historical legacy of a heavy-handed attempt by William and
me
to implement schemes "from the book" (aka Hartshorne):
sage: A = AffineSpace(2, ZZ)
sage: p = A(0, 0)
sage: p.parent().category().element_class
sage: type(p)
It is mathematically correct to say that a point is a s
Hi,
1. (On Sage syntax):
For the record, there are some reasons why ZZ in Fields doesn't
(and perhaps shouldn't) make sense: Fields is a function not the
category it returns:
sage: Fields
sage: Fields()
Category of fields
I think a student learning Sage should have a first session in which

Both m
matplotlib is only used for some of the examples with CVXOPT; there is no
reason to introduce such a dependency. If it's a matter of automated
tests, then it would be much better to comment out the
plotting in the few examples.
