I've logged onto the MAA website twice now and don't even see the March CMJ
available online, let alone that article. I hope it becomes available soon.

I know you said to move along if I don't upgrade, but I would like to
upgrade if it weren't discommended or unreliable, for reasons (A) and (C).
I actually thought it was discommended. I really need to pay more
attention...

I've been teaching a one-semester course on "Mathematical Computation"
using Sage for a while, w/the slides posted online. (Latest:
www.math.usm.edu/perry/mat305sp13/) The textbook we usually use is a
Python-based textbook, and it doesn't always mesh well with the class. I've

I'd be willing to help with this. Aside from having worked with you on a

algorithms of Caboara and Gritzmann and Sturmfels, using a new technique. I
also have some stuff you could probably use for introductory mate

I sometimes illustrate techniques of polynomial factorization in a class by
starting with a polynomial in ZZ[x] and converting it to a polynomial in
GF(insert_large_prime)[x]. I realize this is not an instance of two
_finite_ fields, but (a) you mention "the characteristics are different",

Well,
On the other hand, a student could combine the two ideas, or work on the
interactive plots within the cloud, so as to prepare for a future move to a
"personal" version. (Hint to students who read this.)
Incidentally, the cloud interface looks really nice. It's kind of sad that

I'm trying to build Sage from source on Mavericks. It quits when trying to

Mavericks is up-to-date; extra packages installed. I'm not finding an
option for "command-line tools" in Preferences->Downloads as per the
