Instead, it is a complementary approach to address the many challenges that arise in the development of complex software systems that are often built outside of a traditional corporate software develop...

This position paper provides an overview of the Open Source Software movement and defines how companies can approach, exploit, and learn from it. More specifically, this position paper will first provide the needed details on Open Source licensing models – a key element to be aware of in order to safely approach Open Source. Then, it will provide motivating rationales for getting involved in Op...

SUMMARY We have implemented k-means clustering, hierarchical clustering and self-organizing maps in a single multipurpose open-source library of C routines, callable from other C and C++ programs. Using this library, we have created an improved version of Michael Eisen's well-known Cluster program for Windows, Mac OS X and Linux/Unix. In addition, we generated a Python and a Perl interface to t...
