SETI

is the program my computer runs when it has not much else to do (when it has nothing to do, I switch it off to save the planet). I don't know what the odds are we will really meet E.T. one day, but I think this is a great illustration of distributed computing and how far you can go with a limited budget and a great idea.

Thanks for all the spam!
You may have wondered about the

ASPAM
In 2002, I started to be submerged by spam email, so I wrote an anti-spam tool. I still think it uses a quite original approach based on 'private' keys. Although
even Microsoft promoted a similar idea later, the concept never took off. I keep it online mainly for nostalgia :-).
