IT management at Earthweb has come up with a list of open source tools which can be used to replace commonly known ones. Why? Sometimes you have to work cross platform and it’s good to have software which will work on all OS so you are not changing what you do all the time from one OS to the next. Secondly, if you use Ubuntu or another Linux OS you are not always sure which application to use for the ones you know through Windows or Apple. Thirdly, open source software is free and evens out the playing field. This link gives you 50 applications to try our but also points you to other links which are specifically designed to collate IT materials for educators.
