Hello,
Okay, we are doing another rc3 release. rc1 and rc2 never saw the
light of day on the mailing list, but if you hang around in IRC
you would have seen them wiz by. This is now being build on all
the various boxen we have access to. It should pass doctests
everywhere. The 186 MB tarball is a

We currently have no way to compute svd of sparse matrices.
Scipy has an experimental wrapper of arpack
http://www.caam.rice.edu/software/ARPACK/
which can computes eigenvalues of sparse matrices and svd which is now
built with sage, however,
only the eigenvalue functionality is wrapped.

Sure William, done. Like oh so many things, once you know what to do,
it's trivial! JV

Hmm, this is interesting. Singular may be frightening for factoring with some
big bad examples, but it seems we've got some work to do for the small cases.
sage: R.=QQ[] # singular
sage: r=y^37-1
sage: timeit r.factor()
1000 loops, best of 3: 1.04 ms per loop

Hello,
Bug Day 7 turned into a 23 hour coding session for some of us.
So I am quite tired and don't really am up to remember all the
details. We merged *a lot* of tickets, I will write a proper
summary for 2.9.rc1 or 2.9.final. I would like to thank everybody
who participated in Bug Day 7.

I just had this funny thought:
People come up the aisle from the Maple/Matlab/Magma/Mathematica booths
to the Sage booth asking, "So how much does your software cost?" After
talking with them for a few minutes about what the important questions
in math software are and giving them a free DVD
Forget the paper copy, except for a paper insert in the dvd paper case.
I have DVDs on the shelf here that cost $20 per 50 or a total of $40
for 100. The Memorex DVD sleeves (100/box) is marked $3. So we're
talking $43 total for the materials for 100 DVDs or $0.43 per DVD.
Surely the project can
