Database Size versus Shannon's Word Entropy

[Rick van Rein]

Hi Matthias,

You mentioned that the write volume would increase when last-read was
recorded; but in update mode you would write anyway.

Also, are you aware that statistics has an elegant method of gradually
and continuously forgetting things?

It' like specifying the count and date all in one float :)

In terms of user facilitation:
Grouping related activities together, protecting privacy by keeping them
separate and having independent ACLs on each.

In terms of Bogofilter delivering to multiple recipients:
Use of the term scoring to figure out what alias would be the most
likely recipient for a message.  So, not spamfiltering, but
subclassification of the content on the non-spam side.

Thanks for the pointer; I also have no idea (and am really just playing
with the scope of facilities that this filtering technology could
achieve).  It might just fit very nicely in our architecture (we are
designing a more powerful open source software stack for hosting providers).


Thanks for the responses :)
