Holiday Greetings,

We are happy to announce the first official release of Stick, the  
Scientific Code Kit for Ruby.

[http://stick.rubyforge.org](http://stick.rubyforge.org)

Stick is a spin-off of Facets’ units.rb --the most excellent SI type  
system library by Peter V… This library, and its new  
cousin currency.rb, provide a very powerful system for working with SI  
typed and currency values in a Ruby-esque way. For example:

10.m / 10.s #=\> 1 m/s  
1.bit/s + 8.bytes/s #=\> 65.0 bit/s  
1.mile.to(feet) #=\> 5280.0 feet  
1.acre.to(yd**2) #=\> 4840.0 yd**2

Alson with the units system we’ve added a new matrix library which  
includes the Cosmin Bonchis extensions from his Google’s Summer of  
Code 2007 project. Typed matrix operations are also possible:

Matrix[[1,2,3]] \* 1.kg  
=\> [[1 kg, 2 kg, 3kg]]

Fun! Fun! 🙂

In addition to the units and matrix libraries, STICK has a large  
collection of natural constants, based on the original compilation by  
Daniel Carrera and Brian Gough (hats off to you guys!).

The goal of the STICK project is to provide a valuable resource for  
science and math oriented developers who like to use Ruby. If you have  
any libraries that you feel would make a good fit, please let us know.  
And if you find this project useful please consider donating a little  
time to further polish it up.

This is the first public release for this project --despite the  
version number 😉 So please let us know if you run into any issues.  
Also, note that the currency conversions are not currently working –  
the back-end service we were using is no longer operational. We’ll fix  
this as time permits.

Thanks and enjoy,

```
               Trans & Peter

```

Hey Trans and Peter, thanks! I have a huge use case for this lib.
