[sage-support] Server connection problems - which are likely linked to enclosed code.
Essentially, I'm having problems understanding this "unknown required load command" code. I'm unable to connect to the server, or even access sage through terminal.

You an also use comments if you want to have some sort of explicit end
marker.
for i in range(100):
print i
print i^2
# end for
I used to do that when I was first learning Python.

So I have this chosen set of points which I don't know is convex. I compute its convex hull. Now how do I compare these two objects?

[sage-support] Re: notebook does not leave enough vertical space

I find that the notebook often cuts off the top half of output

sigma,x,0,z);
Here is working code for someone that wants to try that example:
var('x,a,mu,sigma,z')
assume(z>0)
y=integrate(x/a^2*exp(-x^2/2/a^2)*exp(-(x-mu)^2/sigma^2/2)/sqrt(2*pi)/
sigma,x,0,z)
y
My guess off the top of my head is that it is because jsmath doesn't
give the browser good feedback on how high the output region should be.
A work-around could be adding a vertical scroll-bar (but I'm not sure
that would work). Another thing to try is moving to mathjax.

I think in general you open a ticket on trac. http://trac.sagemath.org/sage_trac/ I find http://trac.sagemath.org/sage_trac/report/33 [recent activity] the most useful front page. In this case I think I see what the problem is, so I've opened a ticket and put up a patch, #10841.
