Frankfurt and Seattle
Long time programmer, prefer numerical or graphics programming. Current languages are R, C#, Python, PowerShell, in that order.
Past languages (that I was once good at but have not used in several to very many years) are Perl, C++, C, Pascal, Prolog, Fortran (and of course Assembler...). OpenGL and PHIGS (anyone remember that?) are also obsessions from my past.
