Freeware... because the software police will eventually carry mace.

JumpCut and Clipboard Buddy


Clipboardbuddy
Mac OSX, Windows
Both programs are what is commonly called clipboard-buffers. This means they will quietly sit in the background on your computer and store things that you cut or copy to the clipboard. After using one for a bit you will find yourself wondering how you ever got by with only copy/pasting one bit of text at a time. JumpCut is for OSX and Clipboard Buddy is for Windows.

Bonjour Browser

The application will scan the LAN for any nodes which are Bonjour enabled, and present them in a single window.

Mac OSX, Windows, Linux
Angry IP scanner is a very fast IP address and port scanner. It can scan IP addresses in any range as well as any their ports. Useful in analyzing firewall rules and security concerns. It is cross-platform and lightweight.

Disk Inventory X and WinDirStat


disk inventory x
Mac OSX, Windows
Both programs are similar in function.  DiskInventory X works in OSX, WinDirStat in Windows.  When opened both programs index the files and folders on your hard drive (this could take awhile), then display the sizes of said files and folders graphically.  This helps answer two important questions:
1.  "Who is taking up all the space on my file server" - Network Admin
2.  "How do I get rid of this message saying my startup disk is full" - User

Wink


www.debugmode.com
Windows, Linux
One piece of freeware I really wish they made for Mac. Wink is a Tutorial and Presentation creation software, primarily aimed at creating tutorials on how to use software (like a tutor for MS-Word/Excel etc).  Since you can save in flash format Wink makes it extremely simple to publish your tutorials to the web.

Image Tricks


www.belightsoft.com
Mac OSX
This is not so much a image editing program as it is a image manipulation program. With Image Tricks you can apply a large number of effects to pictures using the core image filters built into OS 10.4.

MyHome


software.relevantwalk.com
Mac OSX
An excellent addition to any elementary school who uses locally managed accounts in OSX and has students manually mount their home folders.  Just put MyHome in the dock, and no more "I forgot how to get to my server."

Carbon Copy Cloner and Netrestore


bombich.com
Mac OSX
Both written by a Mac administrator's best friend... Mike Bombich.  Much like Norton Ghost for windows, Netrestore allows you to create disk image files and "clone" computers through a network connection.  Carbon Copy Cloner does the same but between two local disks.

OpenOffice


openoffice.org
Mac OSX, Windows, Linux
The open source alternative to Microsoft's Office suite of programs.  I have been using the software for a couple years, and have been amazed how quickly it has matured. Open Office can read/write the common Microsoft formats (.doc, .ppt, .xls), and has the useful ability to save slide shows as flash movies.  Unfortunately it is not an OSX native program and must be run inside the the X11 window system.  I recommend NeoOffice for the OSX folks.

Smell-O-Mints


www.jschilling.net
Mac OSX
The periodic table of elements never looked so good. With an aqua and brushed metal interface, this periodic table will display basic characteristics of each element when you click on them.

Great for presentations or demonstrations on the computer. Mouse Locator will put an target graphic around your mouse cursor whenever a set hotkey is used.

pdfcreator

Every Mac user knows that you can create a PDF directly from any print job in OSX.  But did you know you can get the same functionality in Windows?  Enter PDF Creator.  A free tool which will act as a virtual printer, and create PDF files from any print job.

ClamXav


clamxav.com
Mac OSX
Free virus scanning for OSX.  Yes it's true that viruses, for the most part, do not effect OSX users.  However, since most of the world uses Windows it is a good idea to make sure you are not emailing something harmful to your fiends and colleagues.  It also will scan for macro viruses which are a problem if running Microsoft Office on a Mac.

QuickSilver


blacktree.com
Mac OSX

Possibly my favorite utility ever created for OSX.  It is hard to describe what the program does exactly.  But I guess it could be called a application launcher.  Basically you press the specified shortcut key, and then start typing the title of what you want to launch be it a program, address book entry, bookmark, etc.  Sounds simple, but it can have a big impact on the way you navigate OSX.

MacTracker


mactracker.ca
Mac OSX, Windows
A helpful program for people in charge of maintaining or repairing Apple products.  It is basically a database of all the specifications for every Apple product ever made. Constantly updated with new products by the developer.

A very nice interface for editing sound files, or recording voice.  It is a great choice for teachers interested in doing a podcasting project.

Integrity and Xenu's Link Sleuth


Xenu's Link Sleuth

If you run a website, it is always a good idea to check peridically for broken links. These two programs are the best automated link checkers I have found. Integrity for Macs, and Xenu's for PCs.

Picasa


picasa.google.com
Windows
An excellent piece of software made by the folks at Google to organize, edit, and share your digital photos. Very much the equivalent to iphoto for those poor people not fortunate enough to have a Mac.
