Right. I'll have to revisit it and see what's new.

I know. I helped write it after all :p

I think I'll find a way. Thanks for the tip though.

Well, it'll be ambiguous even if one char is stripped from it, so just
cutting the name at 30 chars might be worthwhile if we're on oracle.

Well, unless I'm mistaken IDO will have the same database layout as NDO,
so it will still suck for performance, and writing good queries for it
will still be a major headache. When the storage model of the algorithm
algorithm is broken, tweaking it doesn't really help. Only a rewrite
can save you then.

It would be neat to see Merlin adapted to Oracle though, so if you're
interested in working on that we'd sure help as much as we can.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
