My name is Daniel de Matos, I am always on the irc as tcleval, but not always talking ^^. I use tcl for scientific applications and data acquisition , these softwares are used for a small group of scientists, basically friends and people that work with me.
I also like haskell (need time to learn it for real), scilab (very productive if you use it together with tcl), C (not C++), and assembly (old school).
