This tip involves replacing the image that displays on Safari's error page. The default Safari compass icon can be changed to whatever you like.

The image I use is a small portrait of Homer Simpson. If you want to use it, download it here. Unzip the file.

(If you prefer to use your own creation, it needs to be named "error-page-icon.tif", saved as a TIFF file with .tif extension, and it should have either a white or a transparent background.)

In your Applications folder, Control-click (right-click for those with a 2-button mouse) on Safari and choose "Show Package Contents".

Drill down through the 'Contents' folder and open the folder marked 'Resources'. Drop the unzipped file into the 'Resources' folder.

When the Finder asks you if you want to replace the already-existing file, simply click on 'Replace'.

Close the window and run Safari. The next time an error occurs you should get your first view of your custom icon.

To test it you can type in a non-working link such as http://woksrule.com.

iTunes Remote Control lets you control another machine's iTunes playback over a network.

iTRC is a Universal application, so it will run on (and between) Intel and PowerPC Macs seamlessly. It is free and open source.

Setup is simple, just enable Remote Apple Events (System Preferences->Sharing) on the computer that is running iTunes. Make sure there's a network name entered in the 'Computer Name' field.

Open iTRC on the computer you want to use as the remote control, and type in the network name of the iTunes server. Authenticate with the username and password of the currently logged-in user of the iTunes server computer, and you're off to the races.

It provides support for track changing, playlist and EQ selection, and control of Shuffle and Repeat functions. It also includes Growl support. Works (for me) with iTunes 6 and 7.

Gotchas:

-Make sure to add ".local" to the end of the iTunes server's network name.
-Do not use the Keychain option to store your password, the program will crash on launch.
-Make sure the username is correct, as it defaults to your current machine's username instead of the remote one.

It seems Apple has added an option to the QuickTime Preferences in the System Preferences, and have opted to set the default action to disabled.

Since Flash is quite pervasive on the web, it isn't beyond reasonable doubt that Flash could be an attack vector for malware on OS X, the way it has on Windows, so I guess I could see the logic in having it disabled by default. Seems unlikely that QuickTime would be at fault, when most people use Adobe's Flash plugin for the majority of their content.

However, as Martin Karr noticed, this breaks Apple's own applications, such as iCal's alarm clock graphic in notification windows.

Modifier Keys:

Command: The Command key, identified by the cloverleaf symbol () and Apple logo () also used to be known as the 'Open Apple' key.

First off, go to the View menu and select both the 'Status Bar' and 'Text Size' items. The status bar is at the bottom of each page, and will help you see what type of link you're clicking on, usually with a description of what type of action, if any, the window will take.
The text size of the page you are reading can always be enlarged from the keyboard (Command-Plus and Command-Minus; covered in more detail here) but it's always a nice option to have in the Safari toolbar.

Next, choose 'Preferences' from the Safari menu and select 'Tabbed Browsing.' Check the box needed to enable tabbed browsing. You may wish to use Panther's Keyboard & Mouse Preference Pane to modify the keyboard shortcuts for the Next Tab and Previous Tab commands to something more convenient than the default Command-Shift Right Arrow/Left Arrow.
