For what it is worth, the SageMathCloud docker image includes
sage-7.5, built from source:

It's bigger, since it also contains latex, sagetex, a local

Better bug report -- a one-liner breaks in sage-7.5 but worked in
sage-7.4. It's
P. = PolynomialRing(RR, 3, order='lex'); I =
ideal(x^2+y^2+z^2-1, x^2-y+z^2, x-z); I.groebner_basis()

I gave an updated talk about sage history / funding, etc. yesterday as
part of the "Wing Lectures" at Rochester...

There's a link to screencast video as well. The beginning is similar

That is my understanding/guess, and we could probably deprecate it or
consider it unsupported/experiment

Lock your computer properly when not in use, and use a good password. Full

Hi,
Does anybody have an "executive summary" of the status of Sage and
Python3? Many people keep asking me, and I don't have a good
answer.
