Certainly the old Sage hands recall you.

We still have access to a Sparc Solaris 11.4 machine, not much time to get
the port fixed again, though.

https://trac.sagemath.org/ticket/24596
(marked closed, but it's cause we for a while didn't have access. needless
to say, it's mostly academic interest now,
an example of a big-endian box)

Re: [sage-devel] Problem building sage 9.2 on CentOS 7.9

2021-04-16 Thread Dr David Kirkby 
Thank you. I never see thata. I'm using a laptop to connect to the 
workstation, via a WiFi link, which might be the issue. 

I was rather looking for a "stable release", rather than a release 
candidate, as in general software at least, the stable releases have less 
features, but less bugs. But maybe that's not appropriate here. 

You may recall me from years ago porting Sage to Solaris. I have all but 
given up with Solaris now, and are interested in learning some number 
theory.

I'm fairly certain I built 9.2 on this machine before, but it failed this 
time.

Since a while I see on Gentoo (with the profile

File "src/sage/misc/sageinspect.py", line 2251, in
sage.misc.sageinspect.sage_getsourcelines

all these incompatible libs are 32-bit libs (on a 64-bit system). Is
it a Sage (cython?)  bug/feature, or is there something else that can
be done, short of removing all the traces of 32-bit libs from the box?

[sage-devel] Re: Graded algebra with finite degree

2021-04-16 Thread sver...@gmail.com 
Michael,

I have been participating in writing a package for representing finitely 
presented modules over the Steenrod algebra (awaiting review):

https://trac.sagemath.org/ticket/30680
"
This package implements finitely presented modules over the mod p Steenrod 
algebra. We define classes for such finitely presented modules, their 
elements, and morphisms between them. Methods are provided for doing some 
homological algebra, e.g., computing kernels and images of morphisms, and 
finding free resolutions of modules. 
"

As part of this we created classes within the Sage category framework for 
representing modules over graded algebras in a more general context.

Our focus is on modules over finite graded sub-algebras of the mod p 
Steenrod algebra, but the class FP_Module implemented in fp_module.py (and 
auxiliary classes for elements, homspaces and homomorphisms) is written 
with the intention that it could be used in conjunction with other graded 
algebras than the ones coming from the class SteenrodAlgebra.

We implement modules rather than algebras, so this is not what you are 
asking for, but I thought it was related and could help you put things in 
context.

Good luck!

Sverre

I've updated sagecell install instructions a bit, to explain that it helps
