I noticed the distinct lack of a positioning option in iChats Windows menu, so I added one. Throw this script in Library/Scripts in your home directory, and you can select it in the Scripts menu to tile your iChat windows.

tile iChat windows tiles the windows in a square pattern (i.e. rounds up to the next square number above the open message windows, then divides the screen into rows and columns by that square and fills in til it runs out of message windows). This leaves some screen real-estate unfilled, but wont distort your windows into weird sizes.

Validate at W3C is an AppleScript that gives you a contextual menu item in Opera to submit the current page to the W3Cs HTML validator.

Cascade Nested Folder Windows 1.0 is an innovative and versatile script which organizes size and position of all open windows of nested folders in the desired parent folder.

It combines the Akua Sweets folder walking method and a folder action script designed by Sal Soghoian of Apple Computer. The main differences between this script and Sal's script is that it performs the action on all nested folders and not just the ones in the parent folder, and that it comes in three forms: one suited for use as a draggable Finder application, one suited for triggering from the Apple menu, and one suitable as a folder action . By default it only rearranges nested folders whose windows are open when it is activated, but it can be quickly and easily modified to perform the action on every nested folder in the specified parent folder.

HTMLValidator is a useful software created for web designers, a tool that allows you to verify that your webpages meet W3C html and xhtml standards.

Because HTMLValidator uses the same validation technique as the official validator you can be assured the the pages you create work correctly.

HTMLValidator works without access to the web. This means that you dont need an active internet connection to validate pages and nothing is sent over the internet during validation. Your pages remain secure and you dont need to open your firewall to validate your intranet.

HTMLValidator also has some Applescript support, so you can script the validation and see the errors.

This is only the first release of HTMLValidator, so please send in any ideas or suggestions (or bug reports if necessary)

Uses a checksum calculation to validate credit card numbers.

Checksum Validator 1 is launched as a simple yet effective tool with which you can easily calculate and validate checksums (SHA-1 or MD5 digests) for files that you download (or will upload). By comparing a site's published checksum with your calculated checksum, you can verify that your download matches the site's official copy; free from corruption or tampering (unless the site's checksum was also tampered with).

Everything needed to calculate checksums is in Mac OS X, this is just much easier and quicker, and let's face it, the easier and faster, the more likely you will actually verify these downloads.
