[Newbies] (no subject)

[John Foster]

This might be what I really need, as I was going to develop a whole series
of morphs for different types of drill.  I'll see if this can work with a
live ubuntu or knoppix CD.  I was going to leave the problem of how to
format integrals for another month.  This way I only have to vary the
logic of being sure the problems are appropriate difficulty, but the
display logic can be the same whether it's simple arithmetic, calculus or
algebra.

Using a live CD also means I can cut out network support, which makes it
easier to get it used in schools, as the only support/security issue is
that the machines be able to boot from optical disk.

I'll play with all these ideas, but using Tex seems like it will make the
bigger goals less daunting.

Thanks,

John
