[PhillyOnRails] Thanks for Ruby on Mac responses; follow-up questions on Ruby back-end graphics...

[GREG NEELEY <greg_w_neely@yahoo.com>]

June 5.

Thanks to all for responding with Ruby on Mac build
and usage experiences.

Last week, I built the trial for Qt4.3 downloaded from
the TROLLTECH website on an old AMD LINUX box to
check out the graphics.  I'd read in Hal Fulton's
book,"The Ruby Way",
that one front-end graphics alternative is to use
QtRuby for the active GUI elements.

I was impressed by the Qt4.3 demo, particularly the
back-end animations, even though it took a couple of
hours to built their C++-based product. Haven't tried
QtRuby yet.

1) Has anybody tried QtRuby for back-end graphics from
Ruby output?

2) What back-end graphics packages for basic signal
processing and simple x-y plots are available?  I'm
thinking about
something like a "MATLAB", that offers some basic
signal processing functions such as convolution,
autocorrelation, and some other simple linear
operations.

Gary Margrave in Calgary has a book out on signal
processing fundmentals for seismic data using
"MATLAB", and I thought I'd try some simple coding
with Ruby if I could produce some comparable graphics.

Mac graphics with Quartz look promising, too.  Thanks
for the news on Ruby and Leopard.
