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

EverSave


www.tool-forcesw.com
Mac OSX

EverSave is a clever tool which allows you to save all of your documents - if possible - in a specific time interval or by changing the frontmost application. This means no more data loss if applications crash.
OS 10.7 (Lion) has this ability built-in!

Skype


www.skype.com
Mac OSX, Windows, Linux
Voice over IP for the world. Chat, video chat or call anyone in the Skype network for free. Pay a monthly or per call fee to call regular phones and have your own number.

Deploy Studio


deploystudio.com
Mac OSX, Windows, Linux
Made by Apple engineers in France (though not offically sanctioned by Apple) Deploy Studio is an excellent replacemnet for the now end-of-life NetRestore. With Deploy Studio you can create a master image of any Mac or PC and clone that image through your network to any number of other computers. BUT WAIT, there is so much more. The program is designed so you may easily setup pre and post imaging events in a workflow. So as an example, you could setup a workflow for your school's video production lab that went like so:
  1. Create two partions on the drive one for OSX one for Windows.
  2. Blast my mac and PC master images to those new partitions.
  3. Install my video editing software.
  4. License said video editing software.
  5. Run some more post install scripts.
  6. Setup the proper network settings, and bind this computer to my directory.
  7. Etc, etc.

Google Earth


earth.google.com
Mac OSX, Windows, Linux

Well if you have yet to try out Google Earth you are missing out. This program is an amazing geographic vistualizer and mapping tool. Check out Google's education site for suggestions on how it can be incorporated into the classroom.

iConcertCal


iconcertcal.com
Mac OSX, Windows
Being a big concert goer I was so happy to stumble onto iConcertCal. It is an iTunes visualizer that will show you upcoming concerts and CD releases for the bands in your iTunes library. With nice rollover effects and direct links to buy tickets I think I can finally stop pouring over the early warning section of The Reader.

Scribus


www.scribus.net

An open source professional page layout program, very popular on the Linux platform. Features a clean user interface and advanced functions such as color seperations.

Omni Dazzle


www.omnigroup.com
Mac OSX
Adds all kinds of fun functions to your mouse when doing presentations via a keyboard or mouse hot key.

Firebug


getfirebug.com
Mac OSX, Windows, Linux
I consider this Firefox addon a MUST for anyone involved in website development. With it you can view and edit the source and CSS code for sites your building IN REAL TIME while viewing the pages in firefox. Use the built-in inspector to drill through your own code or to see what other sites are empoying. Try out the debugging console for javascript or PHP. Validate your code. Get that placement just right with the DOM editor... and so much more.

Google Chrome


google.com/chrome
Windows
Google's newly launch web browser Chrome has got to be the fastest one out there for Windows. You can tell they put a lot of thought into it's clean design (what they are calling "one box") and interesting features (favorite thumnails, application shortcuts, crash control, etc).

Gawker


gawker.sourceforge.net
Mac OSX
Makes time-lapse photography/movie making extremely easy using the built-in iSight on the new macs, or any attached camera. Just input the interval between frames, and what movie output you would like. Interesting also is it's ability to attach to remote cameras attached to other macs through bonjour.

NHR


mac.softpedia.com
Mac OSX
Network Home Redirector is a series of install packages for OSX which simplify's the task of redirecting the cache stores for things like fonts and Microsoft Office when you are logged into a network home folder. Before now this process was complex to setup, but essential in districts using Network home folders in conjunction with Microsoft office.

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.

MAMP and WAMP


www.wampserver.com
Mac OSX
The ultimate web programming and design test tube.  Both WAMP and MAMP are self-contained environments running Apache, MySql, and PHP.  Meaning you can develop "traditional" websites and/or complex CMS web portals from the comfort of your personal computer. No knowledge of setting up web servers is required. WAMP is for Windows, and MAMP for Mac folk.

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.

SpamPal


www.spampal.org
Windows
An in genius open source program which works to filter out spam email on your Windows computer.  The program works by actively monitoring traffic coming into the POP and IMAP ports, and therefore does not need to be setup for a specific email client (making the setup very simple and effective).

NeoOffice


neooffice.org
Mac OSX
What could be better than the free feature-rich OpenOffice program suite?  How about an OSX native  version (no need for X11)!  In addition to word processing, spreadsheets, and presentations with NeoOffice you can create drawing documents, HTML pages, business cards, and master templates.

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.

SpiceWorks


www.spiceworks.com
Windows
Is a network monitoring and inventory type software.  It can track and give all kinds of details about nodes on your network (PCs, Switches, Routers, Printers, etc). Unfortunately it must be run from Windows. But it can report on OSX, Linux, and Unix stations just fine.

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.

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.

TrueCrypt


www.truecrypt.org
Mac OSX, Windows, Linux
Creates encrypted virtual disk files for storing data which must be kept secure even in the event that your computer is stolen. The program can also completely encrypt an entire disk, such as a USB key chain.

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.

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

Img2icns


www.img2icnsapp.com

You can set the duration, intensity, and hotkey combination.  In addition, Mouse Locator allows you to chose which graphic is used and weather or not mouse clicks should be highlighted.
