Comment: It Depends (Score 4, Interesting) 251

I've set up networks where the server infrastructure itself is on its own segment, so there's no need for firewalls between the servers themselves, but the whole subnet is firewalled by a border router.

A lot depends on how tightly you can lock down a server. On my *nix boxes, I tend to only run daemons with listening ports to the extent absolutely necessary. I have a LAMP server that basically has ports 22, 80 and 443 open, and everything else either shut down or set to listen only on 127.0.0.1. Do I really need to configure iptables?

And what would you define something that didn't ingest, metabolize, excrete, reproduce and have some sort of system of heredity? Other chemical processes; like fire and crystallization, might hit some of these marks, but we don't call them living systems. So while the precise chemical processes, heck maybe even many of the chemical elements involved may be different (silicon-based life on Titan or something like that), I think at the end of the day if it going to be called life, it has to have the same basic features as terrestrial life.

Why is everyone so uncomfortable with the idea that something can be lost forever? How is that a problem? I'm perfectly sanguine with the idea that information can be lost or irretrievable. I'm perfectly sanguine with the idea that the universe will die of heat death. I'm also down with the idea that the Big Rip will swallow everything up in several billion years - talk about information loss... It just strikes me as fatuous and arrogant that humans think the universe has to work a certain rational, logical, way - like the universe gives a shit one way or the other.

One small step for man, one giant stumble for mankind.

Working...
