On this site you find information about my activities and hobbies.

Bridge: A popular card game. Long ago I developed a program for the ATARI computer.

Recently it has been converted to other Basic versions.

Clavon: An adaptation of a musical notation  devised by a Dutch engineer Pot. Because of some drawbacks it never got the attention it deserved. I revised it to remove the drawbacks and make it more acceptable to users of the traditional notation.

Basic: A well known programming language. The second edition of my thesis pays attention to how to preserve and make available programs written in another version of that language

Philippines: Some pictures.

Some stories

Literature: Some of my publications are listed here.
