Right! <g> Most jokes have some inner core that can be dressed up different. (Some people claim even more ambitious things about inner cores: there was a writer called Arthur Koestler who wrote Act of Creation who not only had a theory about what was common to all jokes, but, indeed, what was common to all creative acts in the sciences and the arts and comedy. Naturally, he bit off far more than he could chew. But I cannot go into this because of my very strict rule here to never stray off topic). -- dorayme

Could you educate me on what I need to type into the Go >> Go to Folder menu command to view the "system log"? (I'm pretty clueless about the Unix underpinnings of the Mac OS.)

Sorry, but power supplies most often fail when you turn them on. Older hard drives most often failed to spin up rather than dying in use. >> I've always tended to agree >> with the latter (ever notice that light bulbs tend to fail more often during >> the electrical surge that occurs when you flip the switch, rather that while >> they're running constantly in steady state?). > >Bzzzzzt! There is no surge when you turn a switch on. The voltage goes >from 0 to 117V almost instantaneously; a "surge" implies that the >voltage overshoots the 117V and then settles back to 117V. It's not a "surge", it's an inrush current. The resistance of a cold light bulb is much less than the resistance of a hot light bulb, resulting in high current flow when the switch is turned on. Power supplies experience inrush current as well, due to the large capacitors in them. Some supplies have inrush limiting circuits. -- The problem with socialism is there's always someone with less ability and more need.

I find Console with Searchlight. The Logs icon at the upper left will toggle the left pane, which lists the logs. The second item is the current system log. Near the bottom are system logs from past days. When viewing a day's log, I type "cron" in the search box. I don't know exactly what the four daily entries mean. |
