I am the author of the official Ruby interpreter interface for the ROOT framework. This project is the content of my Diploma Thesis (University of Athens, Physics Department).

gnewtellium was a complete Gnutella servent built using the GTK+ framework, compatible with most Unix flavors. Due to luck of free time, I'm not able to maintain gnewtellium anymore. The protocol has evolved and it needs a lot of changes for gnewtellium to be functional again.

I can provide guideline to anyone intrested in Gnutella/gnewtellium hacking.

I have contribution in the GNU binutils.

A small patch for the WINGs library, used by WindowMaker.
