Speaking of HoDs ... in Fr. Agnel, Bandra, the HoD actually enforced Linux usage for lab practicals. It was a phase-wise shift - C, C++ followed by uP and finally DBMS and Matlab (yup - they actually purchased a multi-user Linux copy).
BTW. I think part of the motivation for the shift was to thwart malpractices like copying other peoples programs. Most *lusers* don't know how to use floppies in Linux ;-) And those who do are hopefully smart enough to write their own code!!!
