[sage-support] My local sage now asks for a user name and password, what to do?
I have now installed sage for ubuntu (really Lubuntu ...) from the available repository deb http://ppa.launchpad.net/aims/sagemath/ubuntu raring main and my installation is uptodate. Now when starting sage, then saying notebook() it opens a window in the browser which asks for username and password!!! but no way to making such a user. What to do?

[sage-support] solving system of ODEs in sage
Hola!
I tried the following:
u = var('u'); v = var('v')
F = function('F',u)
G = function('G', v)
DEs = [diff(F,u)*(G(u)-G(0))==1,diff(G,v)*(F(1)-F(v))==1]
desolve_system(DEs,[F,G], ivar=[u,v])
but result are:
__main__:1: DeprecationWarning: Substitution using function-call syntax
and unnamed arguments is deprecated and will be removed from a future
release of Sage; you can use named arguments instead, like EXPR(x=...,
y=...)
Traceback (click to the left of this block for traceback)
...
TypeError: ECL says: Error executing code in Maxima: desolve: can't
handle this case.
Any ideas?

[sage-support] Help with programming symbolic expressions!
Hola!
I experimented almost a complete day with the seemingly simple
problem, I want to program a simple function, like:
f(u,v)=\cases{ 2, if u>=v,
0, else.}
and similar functions. As I want tom do calculus, I need symbolic
expressions, not Python functions.
I tries using thing like
step(x) = Piecewise([[(-infinity,0), lambda x : 0],[(0,infinity),
lambda x : 1]],x)
and then
f(u,v) = step(u-v)*2
but it does not work.
Ideas?
Also, Any suggestions about where to read about such things?
