This site, which was for many years the Iris Technologies Australia website, has morphed into a meeting place for the Matters family in Australia. If you would like to contact me, please do so here.
All of the Free and Open Source Software listed on these pages is available free of charge. In other words "free, as in free lunch". In addition, much of the following software is "free, as in free speech". These two concepts, although distinct, are often confused. For an in-depth discussion of Free and Open Source Software see Christopher Smart's article "What is FOSS" or this Wikipedia article.
Please note that the Free and Open Source Software page may include some non Open Source tools which are available without payment while the Commercial Software page may include tools which are Open Source but for which payment is required.
The following pages are accessible only with the appropriate accounts and permissions.
