[sage-edu] hardware/software requirements for a local Sage server

2009-12-11 Thread D.C. Ernst
I'm in the process of exploring the option of setting up a local Sage server at my university. What are the minimum requirements in terms of CPU, memory, hard drive disk space, operating system, etc.? I'm sure the answers to these questions depend on numerous factors, but I'm not exactly sure wha

Dear all, I opened a few tickets based on the feedback from the first Sage Education Day in Cambridge, MA. Some are definitely sage-wishlist, but anyway wanted to point them out. In particular, we really need to fix a few R things (including finally building with the recommended ones, though tha

I run local servers on a 4-cpu computer with 4 GB, and it is fine for smaller classes - but I doubt I've had more than 20 students using it at once. 8GB would scale up a lot better if there might be several classes at a time hitting it. -Marshall Hampton > William Stein wrote: > > On Fri, Dec 1

It might be overkill for this use case, but you can also use the extremely nice real_roots functions that give guaranteed intervals and multiplicities: sage: from sage.rings.polynomial.real_roots import * sage: x = polygen(ZZ) sage: real_roots((x^2 + 1) * (x^2 - x - 1)) [((-3/4, -1/8), 1), ((1/2,
