Missing libraries?

FYI,

Japanese-based “Dennou Ruby Project” is running,
whose aim is to create Ruby libraries for multidimensional data analysis.

A wrapper for GNU Scientific library has been also prepared.

  1. Scientific Library (like python has)

What do people think of just wrapping the GNU Scientific Library?

i have had this exact same idea. i think it would be an excellent start!

I disagree if it only contains symmetric ciphers according to
http://mcrypt.hellug.gr/.

Agreed, only symmetric ciphers are available in that library. Do you see
any glaring omissions in libmcrypt?

Not when it comes to symmetric ciphers.

What we need now is public key method (I’ll have RSA et al packed up
shortly) and then Yarrow for secure random numbers. I think I have some C
code for that also so lets see what we can do.

Having symmetric ciphers (AES, Blowfish et al) in pure Ruby would be
almost meaningless imho…

That’s what I had figured, but I hadn’t seen any hard numbers.

I’d say you should expect about 50 times slower compared to C (since there
will be heavily optimized versions in C available for these kinds of
algorithms). Maybe even 100 with a straightforward Ruby implementation.

I can pack this up and submit to RAA if there is any
interest. >
I’d love to see those.

Ok, expect them in a week or so…
