DavMail has some pretty handy set-up instructions so I won’t go in to that. One feature I immediately missed was the option of not having DavMail’s App icon in the dock. Here’s how to alleviate that problem.Fire up a terminal and run these commands:

• cd /Applications/DavMail.app/Contents
• cp Info-nodock.plist Info.plist

That’s it. The next time you start DavMail the only hint of it running will be in the menu bar.
Add DavMail to your start-up items to have it automatically start when OS X boots.

• System Preferences
• Mission Control
• Check “Automatically rearrange spaces based on most recent use

This allows you to organize your full-screen apps by alt-tabbing through them (yeah not the greatest).

Bonus:
I’m still trying to get used to the three-finger swipes and accidentally alt-tab once in a while. Alt-tabbing once I have my apps organized ruins everything. I’ve whipped up a automator app that simply toggles the preference for you. Toggle it to turn the preference on, sort your apps and toggle it again to turn the preference off.

Tab Settings.app

I’d love to see what people do with it. Here’s the raw apple-script:
tell application "System Preferences"
activate
set the current pane to pane id "com.apple.preference.expose"
end tell

tell application "System Preferences" to close every window

Here’s an updated Automator Service that doesn’t show the System Preferences pane when changing the Alt-Tab setting:

• Start Automator
• Choose “Service”
• Select the “Run Shell Script” action

Copy and paste this into the workflow:
current_value=$(defaults read com.apple.dock mru-spaces)
if [ $current_value = 1 ]
then
defaults write com.apple.dock mru-spaces -bool No
/usr/local/bin/growlnotify -m "Automatically Rearrange is Turned Off"
else
defaults write com.apple.dock mru-spaces -bool Yes
/usr/local/bin/growlnotify -m "Automatically Rearrange is Turned On"
fi

killall Dock

In System Preferences->Keyboard & Mouse->Keyboard Shortcuts
Use the plus sign (+) to create a new shortcut. Use the drop down, labeled Application, to assign our new shortcut to the Terminal.
Menu Title will be “Zoom” no quotes.
Use any keyboard shortcut you’d like, I prefer command+f.
Restart the terminal.

Another keyboard shortcut I use with the Terminal is Select Previous Tab command + left arrow, and Select Next Tab command + right arrow.

Here’s an example:
find ./website/ ! -perm -775 -print0 | xargs -0 chown production:wheel

via linuxdevcenter

Instead of first writing and then reading from a file, it makes more sense to use a pipe. Here’s a quick example:


#!/usr/bin/perl
open (WHOIS, "/usr/bin/whois ewayauto.com |");
$i=1;
while (){
print "Line # ".$i." ".$_;
$i++;
}
print "All done!\n";
close WHOIS;


Thanks to netadmintools for this one.

What you’ll need:

• Proximity 1.0 a free download from Apple.
• A compiled version of notify.c
  #include
int main(int argc, char ** argv)
{
CFMessagePortRef port = CFMessagePortCreateRemote(NULL, CFSTR("com.apple.loginwindow.notify"));
CFMessagePortSendRequest(port, 500, 0, 0, 0, 0, 0);
CFRelease(port);
return 0;
}
  You can download a pre-compiled version here, or compile it yourself (Apple’s Dev Tools required) with the command
  cc -arch ppc -arch i386 -o notif notif.c -framework CoreFoundation
• An Apple Script to set the screen saver
  -- Turn on the screen saver password
do shell script "defaults -currentHost write com.apple.screensaver askForPassword -int 1"
set MyName to do shell script "whoami"
set runFile to "/Users/" & MyName & "/notif"
-- display dialog runFile
do shell script runFile
-- Activate the screen saver
tell application "ScreenSaverEngine" to activate
  N.B. You’ll need to change “/notif” to match the location if the compiled notif binary
• An Applescript to unset the screensaver.
  -- Disable the screen Saver Password
set MyName to do shell script "whoami"
set runFile to "/Users/" & MyName & "/notif"
do shell script "defaults -currentHost write com.apple.screensaver askForPassword -int 0"
do shell script runFile
-- Turn OFF the screen saver
tell application "ScreenSaverEngine" to quit
  N.B. You’ll need to change “/notif” to match the location if the compiled notif binary
• Connect your bluetooth device to the Mac via bluetooth.
• Run Proximity, set your device, set the Applescripts

Update:
Mac OS X Hints has a much better setup.
