I've just got a message from the Sage nagbot, which made me bring this up. Does anyone have any comments on #4446? It's outside my maths knowledge, but I've taken some time to review bits of this. The ticket has been open 21 months, and a lot of people have put a lot of work into it. Dave -

Hi Sergey, Thanks for the pointer to ALGLIB - I'd seen it discussed but hadn't investigated. We've pretty much been targeting QQ (maybe really ZZ) since the idea is to make examples/problems for an introductory course without a numerical component. Where we can drop-in an a general exact ring in

Axiom solves this problem by separating the category information from the specific domain information. Thus you can have a categorical implementation that works for every domain in the category but you can supply a specific implementation for a given domain. So a dense matrix and a sparse matrix

For the first time today I build a 32-bit version of Sage on OpenSolaris. This was 4.5.3.alpha0 on my Sun Ultra 27. (I've tried 64-bit OpenSolaris before, with minimal success, though I can build it). A 64-bit build is just too unstable, but a 32-bit one is more usable. I added the following

Hej Johan, It indeed seems to be at the core of a wider problem. The core of the problem seems that sometimes you can represent various objects in different ways. - So in the coding theory example you can represent a general linear code by a generator matrix. While you can represent a cyclic line

I actually think that the part of the discussion relating to inheritance and scalability is quite fundamental for the structuring of Sage.
