Re: Mixed 64-bit system GerH binaries / BillYscripts --> two-sided training? YES!

What Fidelis said is indeed what I was going to suggest if it were
not for a bad net connection and a very unhappy 11-month-old.

But yes, try OSBF for now.  

Actually, one "good" justification for going to a "train both 
positive and negative examples" in libcrm114 is that _in the special
case of just two classes_ .  If you know (ahead of time) that you 
only want a spam filter (and no advanced email sorting) then 
you train one statistics file for spam-matching (positive training)
and that's all.

Then, classifying with that file will yield a 

  "Best match to file #0 (spam.css)"

if it's spam, and the (new)

  "Best match to file #-1 (none_of_the_above)"

if it's not spam.

Advantages:

  1) most users will need only 1 statistics file (not two)

  2) if we go with 32-bit features, then the size of the statistics
     file for Markov / OSB / OSBF will stay the same, but since you
     only need one, then the overall disk footprint and cache requirement
     will drop by a factor of two.

  3) you can still add other file types later.  It just may take a
     little while to train them in.

  4) there will no longer be any difference in how you train classifiers;
     Markovians will train the same as SVMs and neural nets.  No more code
     dependencies!

  5) - and you will be able to mix different classifiers in the same 
     CLASSIFY statement.

So, Ger, what does this look like in a portable 32/64-bit C:

   typedef struct mythical_new_bucket
     { gimme_32_bits  hash;
       gimme_32_bits  in_count;
       gimme_32_bits  out_count:
     } standard_bucketp;

Do I have to use uint32_t (which can't be printed by printf 
without casting?  Or is there some other incantation that Just Works.
