You can remove the Mac OS X version of Octoshape, (Article at Windows Secrets), by running the following command:
sudo rm -r /Users/*/Library/Preferences/Macromedia/Flash Player/www.macromedia.com/bin/octoshape
This will remove the program for all users on the system. To remove it for a specific user, replace the asterisk with the user name.
Remap the following keys: Terminal.app + Preferences: Got to keyboard tab, change mappings for page up and page down to:
Note: [esc] shows up as \033.
Flush DNS Cache
Pre Leopard: sudo lookupd -flushcache
Post Leopard: dscacheutil -flushcache
Configure the Network from the CLI
You can configure your network interfaces from the command line using the networksetup tool. This isn't quite the Unix way to do things, but I'm hoping Apple gets there eventually.
This allows you to change all(most?) of the settings you would find in the network preference pane. To permanently change the static IP address of a given system, run the following command:
# networksetup -listallnetworkservices
This command will list all your network ports. Why you have to call them by their name escapes me, but whatver.
Next, run the following command:
# networksetup -setmanual <network_service> <new_ip> <new_mask> <default_router>
The only funk above is the network_service item. This is really just the network adapter's name. So, to set an IP of 10.0.0.2 with a subnet of 255.0.0.0 and a default route of 10.0.0.1 on my MacBook Pro's ethernet address, I'd do the following:
# networksetup -setmanual Ethernet 10.0.0.2 255.0.0.0 10.0.0.1
Note, you've gotta be root (or sudo it).
This **WILL** persist through reboots.

Leopard Tricks & Hints
So, it appears that there a lot of new looks in Leopard that people don't really like. I'm going to try and consolidate all of those here, with a fix for each. Please feel free to contribute!
Change Screen-Capture Save Location
defaults write com.apple.screencapture location /Users/YOURUSERNAME/Documents/Screenshots
Disable Transparent Menu Bar
To disable, simply type the following at a prompt in terminal:
defaults write /System/Library/LaunchDaemons/com.apple.WindowServer 'EnvironmentVariables' -dict 'CI_NO_BACKGROUND_IMAGE' 1
To use time machine over a network share, simply open up a terminal window and type the following command, exactly as shown:
defaults com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Now, when you have a network share mounted, you should see it as an option in the Time Machine setup options.
Time Machine Backup Interval
- sudo defaults write /System/Library/LaunchDaemons/ com.apple.backupd-auto StartInterval -int 3600
Change 3600 to the new interval, in seconds.
Dock Glass/3D Undo
If you hate the new 3D crap that Apple has bestowed upon the dock, you can disable it and get, what I would term as, a pretty darn good compromise. Simply open your terminal and type the following commands:
# defaults write com.apple.dock no-glass -boolean YES # killall Dock
Alternatively, you can put your dock on the side, and automatically get this new appearance.
Replace Dock Glowing Dots
Get Round Corners

Change Background Image at Startup
To change the startup background image, simply replace the JPG file at /System/Library/CoreServices/DefaultDesktop.jpg.
Lock the Dock
There are multiple ways to lock the Dock in OS X Leopard. The first is to enable Parental controls on a given account, where you can enable/disable the ability of the user to 'Modify the Dock.' This requires a user not being an administrator, which can be a drag if you just want to keep from accidental deletions.
The quickest method is to run the following command as the user who wants their dock locked:
defaults write com.apple.dock contents-immutable -bool true
To make this apply, restart the dock with the following command:
osascript -e 'tell application "Dock" to quit'
To unlock the dock again, run the same command as above, replacing true with false:
defaults write com.apple.dock contents-immutable -bool false
You'll need to run the command above to restart the dock for changes to take affect.
If you've got a directory server, or are running the Server edition of Mac OS X, you can simply enable the dock locking feature in account preferences within the control panel.
Use the dock locking application someone posted to a forum somewhere. Here's a compiled version: Dock Lock.app
