My personal experience differs. I have run windows VMware guests with
512 MB of memory on top of old hardware (
Hi again list,
This time I come with a problem of solving an algebraic expression, the
solution has the variable x on it!
sage: reset()
sage: var('x')
sage: var('mp', latex_name=r"m_\pi")
sage: var('me', latex_name=r"m_e")
sage: f(x) = mp - sqrt(x^2 + me^2) - x
sage: solve(f(x)==0, x)

Hi group!
I was trying to integrate a dirac_delta, but SAGE cannot do so... weird
thing, 'cause that `function' is defined, and in only make sense as part of
an integration.
Cheers.
Dox.

I don't think that running a virtual machine on yesteryear's hardware is a
viable option. Yes you can make it boot but it'll be too slow for productive

That was o
It is possible to define a a program that will take a single language
and produce from it either TeX, Lisp, Sage, Mathematica, Maple,
Maxima, MathML, etc.
That does not solve the problem of taking some random TeX formula, not
using that language of macros etc, and converting it into a CAS
formula.

Having a automated script to produce virtual machine images is a huge
step in the right direction.
Personally I think size (1.4 GB) could be optimize
Since TeX is turing complete and allows macros,
would it be possible to create a set of macros
that are not ambiguous? For instance, an integral
macro that specifies the limits and differential
variable?
\integrate{0}{\infty}{r}{sin(\theta)}
In this case it seems to me that the latex macros

Thank you, this was an interesting read, which motivates me to revise
my current approach slightly. I think that I need to keep more
information in a first pass, in order to correctly handle subscripts
and superscripts. I still don't know how to place

As far as I understand on my side, the problem with parallelization is
that malloc locks threads, therefore I can only parallelize code that

What happens here is that we construct the result one term at a time, and

You probably do not have an alpha version. It would have printed in
