yes it dies if input is required back from the user. Under
a normal maxima session it replies with
2
Is a - 4 positive or negative?
Unfortunately batch mode does not exit but waits for input
from the user. Hence 'processing' never ends. I also
noticed such behavior from a similar sequence:
integrate(x^n,x);
To get around the problem right now you have to use the
assume command. For you instance
assume (a^2 - 4 > 0);
1/(x^3+a*x^2+x);
integrate(%,x);
or in the other case (one-liners work):
assume (n > -1); integrate(x^n,x);
Right now if two people are in a session it should be fine.
As long as the processing is not occurring at the same time
it should be ok. All the command history is right now kept
on the client side. Upon submission maxima recomputes the
entire session and spits out tex to a file and then uses
tex2im to create the png which is then loaded by client. As
long as one client loads their image before another client
rewrites an image it should be ok. For lower amounts
traffic I doubt this will become a very big problem.
I'll look into the telnet idea. Thanks for the advice.
