Strangely hidden from the casual user is a spiffy command line utility that allows you to view, configure, and troubleshoot your Mac's wireless connection. It doesn't appear to be well documented, and judging by the obscure location of the command, Apple probably didn't think it would be too useful for the average Mac user. But the hidden command line airport tool is very useful indeed, so here is how to access it, and how you can use it too.
The first thing you'll want to do is create a symbolic link to the airport command, because it is situated in a very inconvenient location for quick usage.
Disk Inventory X is a disk usage utility for Mac OS X 10.3 (and later). It shows the sizes of files and folders in a special graphical way called "treemaps".
If you've ever wondered where all your disk space has gone, Disk Inventory X will help you to answer this question.
For a quick start please read the readme file on the disk image.
Propagator provides a GUI for pushing out files to Macs on your local network. This is useful for OS X system administrators who wish to update all of their managed client machines with a specific file, most commonly property list (.plist) files.
This functionality can also be achieved using Apple Remote Desktop, but a free alternative is always worth taking a look. My two favorite aspects of Propagator are its Common Places drop down menu for quickly specifying common locations to drop files (such as long ~/Library paths), and it's Set Ownership check box for giving proper ownership of the file to the right user accounts. The option to Lock Files After Copy prevents users (in my case, students and unknowing faculty) from messing with your work, accidentally or not.
Almost a year ago Apple gave us Leopard (OS X 10.5), and along with it came virtual desktops for the masses, in the form of Spaces. For many this was an interesting new way to expand their workspace virtually. For the rest of us [power users?] it was a letdown in execution. What was worse, the third party options looked to be dwindling as well. Last November I called for third party developers to bring the competition - let's take a look at the result of that call to arms.
Dock icons are a quick way to bring a hidden window or application to the front so that you can work with it again. Dock icons are odd ducks - they're activated with a single-click. Most icons are selected (highlighted) when you single click and opened when you double-click. So Dock icons are kind of like links on a Web page - you need only a single click to open them.
