If David Joyner looks at this, I want to ask what is the quick way in
Sage to get code.information_set()?

Hi,
I cannot understand why the following error occurs:
sage: F.=GF(2^4)
sage: G=matrix(2,[1,0,a+1,a,a^3,a^2]); G
[1 0 a + 1]
[a a^3 a^2]
sage: code=LinearCode(G); code
Linear code of length 3, dimension 2 over Finite Field in a of size
2^4
sage: code.minimum_distance()
Traceback
Hi,
I created the ticket 7119 for this bug, and attached a patch.

Hello,
I've written the official citation for Mike Hansen who won the 2009
Spies Sage Development prize.
The 2009 Spies Sage Development Prize ($500) is awarded to

A much more interesting example is this (in Maxima)
fpprec:16
sin (bfloat(2)^1)
-6.104079172368958b-1
which is correct to 16 decimal places.
Making this work by adding in more terms in the taylor series for
sine would be a very bad idea.
Instead, the sine routine first compute pi to 100

Hi,
Does anybody want to work on the units conversion package? The
student I had work on this over the summer is done, but the package
isn't. The code basically works, but the doctest coverage is only
38% and there are some failures. See

I just noticed that David Kirkby encouraged us to put "set -e"'s in
the Sage spkg-install's, and at the time when I was barely paying

I know 4.1.2.rc0 has been released, but William has marked my trac

I commented once on here before that I have used an old Sun Ultra 80 as
heater in the garage in the winter to stop the water freezing.
Well this Winter I'm going to use an HP Visualize C3600 machine as my
source of heat, though if that is insufficient I have an IBM server too.
