Just when I thought my personal record uptime of 160 days on a MacBook server was exciting, one of our readers blew my uptime away… by almost a year!

Seriously, Stephan Burlot‘s personal record uptime? A staggering 454 days with his iBook. Apparently the iBook monitors his homes electrical usage and runs Mac OS X 10.4.11, and so there is rarely a need to reboot the machine, and it basically never gets turned off. Stable, reliable, trouble free. How awesome is that?

If you didn’t know, uptime is just a measure of how long your computer has been running without a system reboot. A long system uptime is a geeky badge of honor of sorts, and obviously a nice sign of system stability. You can check your Mac uptime by typing ‘uptime’ into the Terminal. I’ve had some pretty impressive uptimes on Macs and Linux machines before, but at the moment this current Mac being typed on is at just 24 days… not bad, but certainly not into the hundreds or over a year! Obviously, stable servers will have longer uptimes than personal machines, so your mileage may vary. Anyway, just kind of fun geeky stuff.

Oh and if you have a whopper uptime, do share it with us in the comments. Or even if it’s not that impressive, it can still be worth sharing.
