I would say "number system" rather than "numeral system" - that's the
term that I've seen in recent literature (see L. Germ\'an and A. Kov
\'acs, On Number System Constructions, Acta. Math. Hungar. 115 (2007)
155-167).
This would be quite helpful for my research if it could also be
extended to:

Hi there,
I was looking at solve_right. And as much as I understand if the
system has infinitely many solutions it just generates a random
solution (with free vars = 0). Doesn't it make more sense that it
gives back a matrix :
[C0 C1 C2 ..] such that X = C0 + C1*t1 + C2*t2 + ... be a solution to

Transmission ( http://transmissionbt.com/ ) is, I believe, a popular choice
these days, since the official BitTorrent client went closed-source a few
years back. It can be run as a daemon. I also found a useful-looking thing
named PHP-tracker ( http://php-tracker.org/ ).

Except that the "old one" doesn't exist -- this is pil-1.1.7.p0, not
pil-1.1.6.p5.
Still not sure how to go about this -- an example (perhaps it's in the

There is a static object that segfaults in its destructor. Unfortunately
the name of the instance is not included in the stack trace, but since it
dies somewhere in iostream code I would guess that it has something to do
with LinBox's Commentator.

The MIME registration is a bit screwed up in this respect. "tar"
might be OK as a document format (though I believe no one has
registered a MIME type for it), but bzip2 is more of what they think
of as a "content-transfer-encoding". I've argued in the past to the
IETF that they should define addi
Hi,
after I managed to build Sage on Dave's OpenSolaris machine, I managed to
reproduce a SIGSEGV that Jeroen reported in #4260. Simply starting and
stopping Sage with #4260 gives the following segfault:

#1 0xfec9c7af in free () from /lib

You mention it only segfaults when finite_semigroup-nt.patch is applied.
I assume this patch comes from some ticket. So you should complain on
that ticket.

I disagree that metalinks are "better" than torrents. Metalinks may be
standardized but bittorrent clients do not care about them and most people
don't have a program that can download metalinks (at least in 2011),
whereas almost everyone (in my experience) has a bittorrent client. The
