A couple of the patches I've been working on are failing the new
automatic testing because some ticket attachments are being applied
that shouldn't be -- is there a way to fix this myself without
becoming a trac administrator?

This is the case for every bug I've ever reported to th
How often will / should pari be updated within sage?
I encountered a bug in pari 2.4.3 (alpha) while working on a sage ticket. I
reported it to pari, and they fixed it the same day. But then it takes some
time for this fix to reach sage, or we could update sage with bug fixes
immediately.
I don't
For the record, Polymake switched to jReality (http://www3.math.tu-
berlin.de/jreality) for its 3d graphics recently. So, apart from
nauty, which probably isn't that crucial to Polymake, I think its all
GPL now. I saw a few glimpses of the jReality GUI and it looks really
nice!

Here's what is going on:
There are two arrays, in_degree and out_degree, which count the number
of arcs coming in and going out, respectively. Then the degree of a
vertex is the sum of these things if you don't worry about loops.
If a graph is not directed, then the degrees are doubled, since one

what is the best way to do this? Is there a program or code I can

Hi folks,
I noticed the following inconsistent behaviour while working on ticket
#8395 [1]. Given a multigraph G with one self-loop at vertex v,
disable loops in G and query the degree of v. This should report the
correct degree:

I don't think this is a particularly useful project. The cddlib API

Here's a suggestion:
Make a "concise log" that's loadable in a browser in a small amount of time
(the current log files are too long to be easily readable in Firefox for
me). For example:

Wow, that question got people interested!
Checking a few books myself I was struck by how many advanced texts
avoid using the term at all (for the adjugate or classical adjoint).
P M Cohn's Algebra 1 defines adjugate (p.196).
Maclana and Birkhoff (p.194) call it the "classical adjoint".

That's awesome. This will make me far more likely to review tickets.
