On the 15th of September 2012, Software Freedom Day (SFD 2012) will be celebrated all over the world.
Software Freedom Day honors Free and Open Source Software (FOSS). The Joomla! CMS is both Free and Open Source software.
Open Source Matters, and the Joomla! project, supports Software Freedom Day.
This is what Pia Waugh writes about Free and Open Source Software:
\\\"Transparent and sustainable technologies are vital to ensuring we can protect our freedoms.
So what do I mean by transparent? Well some software gives you access to the source code, such as Free and Open Source Software (FOSS) which ensures that you can know (or get checked) what exactly a piece of software will do.
It avoids nasty surprises, spyware, result rigging and all kinds of issues that we can\\\'t be absolutely sure to avoid in closed software. Proprietary software keeps the source code locked away from public scrutiny which means that there is no way to know exactly what the software actually does, and no way to trust it to safeguard your human rights.
Transparent technologies are about ensuring you can trust the results and operation of your technology.\\\"
This day is to celebrate all open source software.
