Public Sticky notes

) and Linux, soon I was hating the idea of not being able to boot and use Linux. So I've come up with a simple (and obvious) way to boot Linux without losing my Mac OS X uptime.

Definitions and prerequisites
  1. Deep Sleep = Safe Sleep = Hibernate mode = Suspend to disk

Download one of the apps to go straight to Safe Sleep, like the widget DeepSleep or the script SuspendNow!.
