I started as a FORTRAN programmer, paid my dues writing C and X11/Motif, switched to Perl, discovered Tk, and from that, Tcl, and spent the next decade plus writing cross-platform GUIs in Tcl/Tk.

I then spent three years using python and a smattering of ruby to create a cross-platform automated testing framework. I am now working in an all-Windows shop, again building an automated testing framework and still using Python.
