Are you talking about the postscript files produced by dvips?
You probably only installed a small subset of fonts, and scaling them
produces substandard results. It can also be that dvips is set up to
create 300 DPI (dots per inch) docs - this is easy to fix then (but
depends upon a particular
I think that better is to use scalable fonts. this should be default

where, from texlive homepage or from centos repository?

Hello!
I am working with the builtin FFT Fast Fourier Transform of Sagemath,
and have coded (based on the work of P. Lutus here :
http://vps.arachnoid.com/sage/fourier.html) a function that takes an
fftobject to plot the spectrum of a function.
My problem is that when I pass the fftobject, I

Ok. I've found a way (to copy an fft object) :
lfft = len(fftobj)
fftobj_copy = FFT(lfft)
for i in range(lfft):
fftobj_copy[i]=fftobj[i]
If you see things which I could / should do another way in my code,
feel free to post your suggestions!

I am using the latex in Moodle and I had Moodle's latex filter turned
on. I removed it and the fonts are great. Before it was creating an

Hey guys,
Is there any way to disable the auto-login feature when a user
accesses the Notebook server from the machine? Since I'm hosting the
notebook server in a VM and have an outside port forwarded to the VM,
any users that access the server globally get logged in as admin.
Thanks!

Hi,
I've created a poset of permutation elements using the Bruhat partial
order:
bruhat_p_order = lambda p,q : p.bruhat_lequal(q)
my_poset = Poset([perms, bruhat_p_order])
It seems that when I create the poset, the elements are no longer
permutations but PosetElements, and I can't figure out

Two options I can think of, probably a lot more from the elders here:
1) turn off verbose
set_verbose(-1)
f(x) = x^(1/3)
plot(f(x),(-5,5))
2) Don't plot negative
f(x) = x^(1/3)
plot(f(x),(0,5))
-d

Hi,
I know this is not a general mathematical forum, but I hope you can help me.
I have this PDE:
\frac{dB}{dt} = F(x,y,z)B(x,y,z) - G(x,y,z)\nabla B(x,y,z)
and I don't know how to solve it numerically. What would be the easiest
method to do it? It can be in python, but preferably in C++.
I'm not sure I understand. Why can't you just use ${IP ADDRESS}:8000 ?
You'll probably need to port-forward, but that is easy enough...
