Well, I really hate the idea of lots of network pinging, both because it's not reliable for network probing, not reliable for machine load probing, and causes more congestion, so I wanted a way to force loadsharing, one that allowed some feedback so that real backups could be adjusted to. OTOH, there's no way I will try to fight folks with elephantine memories. I even began looking at Modula-3, seeing if I could offer a diff set to jdp. You know what I realized, and (for some reason) no one in my memory has ever written: modula-3, in features, looks a lot like Java. It's not a stylistic descendant of C like Java is, but featurewise, it is. > > Warner > > ---------------------------------------------------------------------------- Chuck Robey | Interests include C & Java programming, FreeBSD, chuckr@picnic.mat.net | electronics, communications, and signal processing.
