comment What are software and hardware interrupts, and how are they processed?
Either interrupt will cause the state to be pushed on the stack. This allows the system to reload the state when it is done with the interrupt.

comment Backing up hard links (rsync)?
You shouldn't expect negative side effects other than increased disk usage. The links should be replaced if you reinstall the related packages. This might happen if you patch something. New /lib/modules directories get created when a new kernel patch is installed. cups uses a hardlink, where most applications would use a symbolic link. This is a rare occurance.

comment Program behavior when kill -HUP is recieved?
@Keith: That's why I indicated that it applies to dropped connections, and is rarely caused by hang-ups anymore. It would be confusing at this point to change its name to something related to disconnects, such as SIGDCN.

SIGHUP goes back to the days of dial-up modems. It signaled a Hang-UP of the modem connection. It still applies to a dropped connections, but these days its rarely a hang-up that causes the connection to be dropped.P

@Gilles: Log analyzers are not at all specific to publicly reachable web sites. Google Analytics may be somewhat specific to publicly accessible web sites as it does require access to the google servers. I am not aware of anything in Analytics that requires public access to the site.
