It's looking like Windows is getting support for the Linux API in its
kernel (think the reverse of Wine) allowing it to run native Linux
binaries.
See http://blog.dustinkirkland.com/2016/03/ubuntu-on-windows.html. It
seems like this might be a great alternative to Cygwin for Sage on Windows.

I'm guessing this is just due to you using dict() in the function
definition. See http://effbot.org/zone/default-values.htm . If you
replace it with None do something like
if l is None:
l = {}
at the beginning of the function, then things should be okay.

I've posted a patch at http://trac.sagemath.org/sage_trac/ticket/10100
which fixes this.

I don't understand this -- they have basically the same error messages:
sage: binomial()
TypeError: binomial() takes exactly 2 argument

It is because you aren't familiar with Python and its conventions.

According to the documentation for is_triangular_number, you should
use the following test if you want to consider 0 triangular:

It is in sage/misc/randstate.pyx.

You can't call it from GAP,

This is what I said in my first response and can be taken care of with
current_randstate().set_seed_gap().

My guess is that it is due to the endianness of the machine. For
example, check out this snippet from sa

Just define X.log()

You could build the dictionary and check that it is equal to the
dictionary in question:
sage: L
{360: {}, 2520: {0: 'X'}, 'prime': 3}
sage: dict([(3

It's always been somewhat machine dependent -- see

You need to use ".. link" to connect a doctest block with the one
above it. For example,
{{{
.. link
::
sage: d.items()
[(1, 5), ('sage', 17), (Integer Ring, Finite Field of size 7)]
}}}
