Hello,
I'm very new to ruby, and I would like to know if there is some
applications known to be well coded in "rubysh style" that I can learn
from. What I would like to see is Ruby in scientific computing,
application design (i.e. I'm not very interested in Web applications) or
glue language (i.e. extension of some other application of ruby being
heavily extended using other languages).
Thanks for your help,
Pierre
i'm doing alot of stuff - mostly little image processing tasks. can you
define what you mean by 'scientific computing'. many people mean numerical
computing by that, but of course there are worlds of scientific programming
that are not numerical in nature. you may find this interesting:

and example of some coding used for science that is not 'numerical'

btw. welome to the ruby group!

There should be a lot of code out there on Ruby extensions written in C.

Thanks, that was exactly the kind of ressources I was looking for ! I'm
very interested in numerical computing, but not only 
My main interest is on structural computing (applied to biology) but it
uses a lot of numerical computation 
By the way, does anybody knows if there is some kind of GNU R ruby
binding ? If not it may be a good project as I think I can begin easily
and improve it slowly ...

Joe Van Dyk suggested that:

Pierre, check out the standard library, which comes with Ruby.
YAML/Syck fits the glue/extension category - Syck is a C extension, YAML is
the part written in Ruby.
You can also quickly and easily write wrappers for binary libraries in pure
Ruby, using the DL library. There are no examples of that in the standard
libary, I think, but they exist on RAA, and I can send you one I made for
AutoIt for Windows if you're interested. (Wrapping AutoIt this way is
redundant, because it provides a COM interface.)
You might also want to check out the Ruby Quiz, which is mostly not that
scientific, but includes different people writing code for the same goal,
and a summary of the solutions given; see what titles strike you at

great - you'll find ruby a treat then.

can you elaborate? i'm not biologist

Great, this seems a good code database to look at
And also I can try first the quizz and compare what I do with what
others do ... Thanks a lot, I also will have a look at the libraries
your talking about.
Cheers,

Well, I'm working on some tissue growth. Tissues are here represented as
graph with nodes being cells and edges beeing the neighborhood
relationship. Computing the evoluation of this graph is largely
symbolic. However, you need to solve some ODE on this graph. Most of the
case these ODEs rule the concentrations of different proteins. Solving
these ODEs involve numerical computation.
Also, to study the structure of real tissues we extract quantitative
data from graph constructed using existing tissues. Once extracted we
can get some hundred or thousand data. We need statistical tools to
study them. And they're not easy (cyclic, spatial, ...) so we need tools
like GNU R and the big number of statistic libraries available.
