Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

sudo pmset -a hibernatemode 1 sets hiberate on.
sudo pmset -a hibernatemode 0 sets hibernate off.
from the pmset man page:
0001 (bit 0) enables hibernation; causes OS X to write memory state to
hibernation image at sleep time. On wake (without bit 1 set) OS X will
resume from the hibernation image. Bit 0 set (without bit 1 set) causes
OS X to write memory state and immediately hibernate at sleep time.
I often change my MacBook's sleep state. So I created a function for bash to make it a little easier.
Usage:
hibernate (on | off)
"hibernate on" will set your laptop to hibernate if the lid is closed.
"hibernate off" will set your laptop to sleep if the lid is closed.
### note : "proper" indentation isn't preserved on the website
function hibernate()
{
case "${1}" in
on)
sudo pmset -a hibernatemode 1
echo Hibernate mode on.
;;
off)
sudo pmset -a hibernatemode 0
echo Hiberate mode off.
;;
*)
echo "I'm sorry Dave, but I can't do that."
;;
esac
}
To make things easier, add the proper line in your /etc/sudoers file so that your user may invoke pmset without a password. Here's how mine looks:
bwayne luna = NOPASSWD: /usr/bin/pmset
Don't forget that you must edit sudoers with `sudo visudo` from Terminal.app, and not by another text editor.
Sorry this is so Mac OS specific.
