If anybody wants to make something in Ada but do not know what

[Preben Randhol <randhol+news@pvv.org>]

Then perhaps a Bayesian Spam filter could be a nice challenge. Or if
somebody are heading a university student project/diploma work it could
a suitable project? 

Spam is becoming a great problem. Last check I got 30 spam messages in 3
days that was caught by my filter (spamassassin) and about 10 that
wasn't. There was also about 3 false negatives (mailed labelled as SPAM
but which was really HAM). So I think it is time for me to change spam
filtering method. Besides spamassassin is a perl script program and it
is a hug resource hog on my computer and it is slow. There are two
Bayesian Spam filter implementations in C (ugg :-( ) which has the
advantage of being fast. Problem is that with C's track record on buffer
overflow I don't trust them to be secure. This is why an Ada
implementation would be nice I think. Besides spam filters is something
people need so it could promote Ada95.

Wish I could make it myself, but I simply don't have the time at the
moment.
