I am married with Cristiane Caratin Perrone
Barreto (in the above photo you see my wife and me a few
minutes after our wedding ceremony on October 8, 1994).
We have a son, Tomás (named after
St.
Thomas Aquinas), born on October 12, 1995,
and two daughters, Letícia (named after the Latin word
lætitia, 'joy'), born on May 11, 1998,
and Sofia (named after the Greek word
σoφíα, 'wisdom'), born on March 16, 2004.
Computer science in general, but notably formal languages, compilers,
data compression, and automata.
Theoretical physics (I have a BSc degree in Physics, remember?).
Musical composition. Here's one of my
compositions; to hear it you will need the Noteworthy Player freeware
(and please keep in mind that I'm an amateur composer).
Linguistics. This means I'm as fascinated by human languages as by
formal ones (see the second item above).
