I've seen the "personal" computer technology evolve from the very beginning. From when the ZX80 was the newst kid on the block, to the born of internet, to the current days of mobile revolution.

I've touched many fields during all these years: hardware, programming, graphics, text processing, font technologies, computer music, ...

I'm now trying to do a "back up" of what I've learned in all these years by sharing code, writing articles and books and teaching to whoever is willing to listen.
