Hi,
I've released sage-1.8.1.
Major changes:
* many small improvements to distributed SAGE: it's now braindead to
setup distributed SAGE and try it out! Just type dsage? to get
going.
* More graph theory (labels, tutorial)
* update to real matrices.

Hi Nils,
Things that come to mind are:
1. LLL (wrapping existing code, not implementing it) and more canonical
lattice reduction
for small dimensions, with attention to what has been done in the
context of quadratic forms?
2. Collaboration on robust p-adic arithmetic -- wrapping and/or testing

I forgot to mention that Sheldon Kamienny, Ming-Deh Huang and I are
starting a undergraduate research project in Number Theory and
Cryptography over the summer.
Perhaps William can give some direction to these concurrent initiatives
and what projects would benefit SAGE and undergraduates and ways

Whoah hang on a second. Something else really bad is
To me, *(1/9) and /9 are the same...
sage: type((f - (x^21 + 3*x^15 + 6*x^9)))
sage: type((f - (x^21 + 3*x^15 + 6*x^9))*(1/9))
sage: type((f - (x^21 + 3*x^15 + 6*x^9))/9)

AFAIK the only todo list is for bugs/milestones

I probably have funding available to let an undergraduate do some work
on Sage for 4 months. I would welcome a list of programming tasks that
need some attention. The tasks should be rather limited in scope,
because an undergraduate should be able to dive in, work, and get some
result within 4 mon

A new behaviour just cropped up in SAGE
If I have a .sage script containing the line
time = float(time)
something in there decides to treat this as timing the line "=
float(time)". I don't know if this is the preparser or what. Apparently
it didn't used to do this because I haven'

Definitely.
I can put this in this weekend, but if someone doesn't get to it
sooner.

Indeed! Thanks for the report; I touched this code last, so I'll look
What does _lcm have to do with valuation in the snippet below? This is version
1.8 upgraded from 1.7.1. The actual function call seems to do what I want it
to
do, but the help seems a bit off.
Also
sage: (3).valuation(1)
seems to go into an endless loop, but I think I can patch that easily en
Hi,
OK, I've now figured out the problem, which is quite severe, but will
be completely fixed within an hour (I'm uploading a new version
right now).
Ifti -- the quick fix so you don't have to build/download again is to simply
edit SAGE_ROOT/devel/sage/setup.py and uncomment line 697
I had the same problem -- my sage/functions directory was missing, and
when I copied it in from an older release everything worked.
