Safe sleep

The Intel-based Macs have a new “feature” called “safe sleep”. On the Windows side, it’s called “hibernate”. Basically, it writes the contents of memory to the hard drive when you ask the computer to go to sleep. This takes time. Previously, Macs would just keep the contents of memory in memory and use a bit of battery power to keep it in there. This delay before actual sleep annoyed me, because I sleep my laptop all the time when I bring it to work and back on a daily basis. Waiting for the hard drive to finish doing its thing was annoying; and I’d frequently forget to wait because I’ve never had to before. So I [found a command](http://www.karppinen.fi/2006/11/22/turn-off-safe-sleep-now/)  to disable this “safe” sleep thing:

sudo pmset -a hibernatemode 0

Voilà. The linked page comes at it from a security standpoint, but I’m not as paranoid as they are.
