Apparently, a sort of idiot ... according to "D.V." but beside this, I am a physicist working at the Department of Physics of the Faculty of Exacts and Natural Sciences of the University of Northeastern and IMIT-CONICET, Corrientes, Argentina. I do not know much on RPI but started to work on it as well as Python, however I understand something of Fortran and some scripting environments like awk, sed, csh, ksh, etc.
