Some of My Personal Interests

Playing chess, playing the piano, developing freeware programs in C, C++, Pascal, Java, Perl.
I used to develop programs in Fortran as well.

Some of My Current Projects

Recently, I rewrote GWD from scratch in C using CodeWarrior,
and added a C++ Builder 3.0 front-end to it.
Currently, I am implementing Kotov's ideas in ZZZZZZ.
I am working on a swiss pairing program for chess/draughts tournaments,
and a version management program.
I am also rewriting some of my Fortran programs in Mathematica.
