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.
Literature: Some of my publications are listed here.
