I noticed that on http://www.sagemath.org/mirrors.html most of the
mirrors are listed as "unknown" although they appear to work just fine
when I checked them out, although they are mirroring the sage.math
stuff. Should we mirror operators be pulling from a different place?

I think Sage is awesome. I've started using it in my research. I've
been using it to teach classes, and I've even forced my students to
learn Python (and Linux) in the process.
Yes, Sage has lots of bugs, but at least I get to see the code, and if
I'm motivated then I can even fix it myself. I
The symbolic link
/home/was/www/sage/pre
points to a non-existent referrent, which causes rsync on my mirror to
skip file deletion (I'm using the "safe" mode for link following in
rsync)... which is making my mirror at least grow a little faster than
it should.
Can this sym link be removed?

The sage mirror I run, modular.math.jmu.edu currently has a full disk,
so it will be down/out-of-date through this weekend when I'll
switch-out the disk with a newer one.

Has anyone tried a 64-bit build on Leopard? I just picked up Leopard
today, so I'll hopefully have a running Leopard machine tomorrow on
which to start playing. Just wondering if, for example, python can
build in 64-bit mode on Leopard.

My vote would be to change the sage license to "GPLv2 or later" and
try to get the Singular developers to do likewise. Mainly because
that is less work.
Does changing Sage to "v2 or later" require Sage to adopted future GPL
changes? My interpretation is that it simply gives users the option

Some thoughts:
1. I've been doing some performance comparisons on GMP 4.2.2 with the
patches that Sage uses, and I haven't seen any remarkable differences
between 4.2.2 and 4.2.1. Granted, I have only tested Linux on
AMD64/Intel64 and OS X on Intel64. Perhaps some other platforms have

I'm interested. I am currently teaching a discrete math class where I

I'm currently testing several of the major GMP patches with gmp-4.2.2.
Should have some results by this weekend.

Hi Bill,
What you may be seeing is Valgrind not being able to detect the memory
aliasing you're using in that complex loop condition ((i <
test_mpn_poly->limbs) && (result == 1)). If you can re-create this
exact error using a similar snipet of code in a tiny example program,
it would be worth se
I looked at LiDIA a long time ago (like 1999 or 2000) and I remember
being very impressed both with its scope and with its modular (i.e.
recursive) data types and programming dogma. However, I decided
against using it simply because of its license. I suspect that other
developers may have made t

I'm not familiar with the MPFI source tree.
This is probably something we should tell the list about since we want
to make sure that Sage builds completely from the components it gets
distributed with and doesn't try to pick up outside libraries.

Just finished getting a new sage mirror setup. It took nearly 28
hours for the initial sync!! (Average connection speed was only
around 100kB/s.)
Anway, when you have time to kill, go to

and let me know if I've mis-configured anything.
Thanks,

If someone who is already mirroring sage could send me scripts for
syncing the mirror and a brief description of the setup, I'd greatly
appreciate it. I'm also willing to run a sage notebook if it's easy
to setup. (However, the dinky pentium4 that I've setup for this task

I've been tweaking the gmp used in sage. Right now this will only
benefit Linux users who have a core2 processor. However, I'd like to

platforms. So, I'd appreciate any and all feedback! Instructions and

I just learned what IANAL means, and indeed I am not a Lawyer, but
point 3c of the Microsoft Permissive License appears to directly

Hi All,
I was able to get 64-bit Ubuntu installed and running in a VMware
virtual machine. Sage appears to build on it, too (that's as far as
I've gotten in testing it). One problem I'm having is that I'd like
to be able to login to the virtual machine remotely. However, I can't

and claims to support 64-bit guest OSes. I'll try it out later this
week and see if I can get Sage t

Take the line with the biggest number and add one to it. Kinda

On Solaris, I believe that "procinfo" will give it
Hi All,

However, I can't get a 64-bit Python to build because not enough of

Python build to accurately use the 64-bit libraries I can get built.
