I'm a bit fuzzy on the language count... It's scary, but I no longer remember *which* languages I've used - probably 15+ if you include stuff like MATLAB, Maple and Bash).
My rough estimate was about right: C/C++, Fortran, ASM, Pascal/Delphi, Powerbuilder/SQL, Java, Python, Perl, bash/tcsh/batch, matlab, mathematica/maple, R/Splus, SAS, Visual Basic, PHP These does not include rarely used things like vim and emacs/elisp... Bo
