I am no professional in the field and this is just a labor of love,
but I think
for some this alternative might be useful. It would be great if

A quick and easy method i.e is UNetbootin (no CD required).

then you could "remaster" the live CD image (maybe make some

I made a guide how to do this here:

Yes you should be able to connect to the sage server.
1) Shutdown Computer and restart
Start VirtualBox
Please check that on the right side of your Virtual Box control
window, section "Networking" is set to NAT.
start Sage VM
In the VM you should get the message that the sage server is running
on
rowser. Internet
Explorer, Firefox, Chrome, Opera should all work, as well as other,
less known browser types. Just open the browser and type in localhost:
8000 in adress bar.

automorphism_group contain symbols that may not be the actual vertices. I
realised this once after several frustrating hours of bizarre results from my
program. I'm not sure if this is still the case in recent versions.

Hi Nathann,
Thanks for writing the MILP class - it works very well. Now, I can do:
x = lp.new_variable()
Is there any way to do something like
x = lp.get_existing_variables()
?
I'm working on some graph theoretic stuff: I'm solving two LPs for
each graph, for as many graphs as I c

Ahh! Thanks, this is what I need. (Is this documented anywhere?) - Emil

Next issue is that the Gurobi backend doesn't support the copy:
AttributeError: 'sage.numerical.backends.gurobi_backend.GurobiBacke'
object has no attribute 'copy'
Any idea how much work this would be to do?

would probably mess it up!)

otup is not necessary when starting a linux
in a fixed virtual environment. E.g. the whole hardware detection stuff
could be minimized. Of course this would mean to use a customized boot
script inside the initrd of the vm ...

I'd like to know if it's possible to get the filename of a script that's
been run using the "load" or "attach" command at the sage: prompt.
If I insert a "print __name__" in the script I just get "__main__".
I know __name__ isn't the right thing, since I'm not dealing with an
imported Python modu
t I might
be able to do something like open(__name__ + ".js", w")...

Hi, I'd like to be able to save number fields with embeddings as text
strings, so that they can be instantiated at a later date, as well as being
human readable. So, I'm trying to store the command used to create such a
field, and use sage_eval on it.
sage: x = polygen(QQ)
sage: K. = Numbe

I am sorry if this question has been asked before.
Is there a way to get the fundamental Lie algebra generators in sage (those
that physicists use, eq. the Paule matrices, Gellmann matrices and so
forth)?
The only thing I can find in the documentation is the generators in the
Chevalley basis, b
