Hi all,

Yes, I'm once more filling this mostly-silent newsgroup with frothing
rants.  Well, nice frothing rants this time.

In a desperate attempt to not do any work, I converted a C++ computational
program that I've been working on over to Sather.  I ended up with a
final program that was cleaner than the C++ one, that was easier to
extend, and that ran about twice as fast.

Like I said, I'm impressed.

The precise problem was an exercise in numeric integration in which I
had integrals of integrals of bessel functions, where I had
approximated the various functions at each step with heavily tweaked
Chebyshev polynomials to ease the computational load.  So, in any case,
it's not vector/matrix math, nor is it complex hydrodynamic simulation,
but it still works, and works well.

On the downside, now I have to think really hard to figure out what all
these nice numerical results are telling me.

Cheers,

- Johann

Sather is a fully object orientated language, which was origionally
based on Eiffel. Although I don't like Eiffel, Sather has changed
quite a lot, and I think that out of all the languages mentioned here,
this one is probably the best.  Sather has taken the good parts from
several languages, including C/C++, Eiffel, Fortran, and others. It
has lots of nice features, and is free.  I am now working on an
interface to the GTK library for Sather. GTK is a widget set for X
windows....

Again, a warm thank you. With such improvements, I am beginning to have my
students say "wow, ..." even if at first contact with Sather, they
invariably comment: "why not c++?".
