Property "Master page" (as page type) with input value "{{{master page}}}" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.
Property "Experience" (as page type) with input value "Since the 10th grade, I have used exclusively free operating systems. My laptop runs Ubuntu. My personal servers run Gentoo, with a home-made ebuild overlay which allows me to use linux-libre. I have played with various other distributions of GNU/Linux and GNU/HURD, but these two configurations remain the most stable.
I try to make advocacy a part of life that doesn't push and pop to the front for special events, but rather an ongoing and constant struggle. While this makes me very annoying to talk to if you are resolutely against free software, it makes me a rather efficient advocate to people I know well. Most of my friends and family, thanks first to the supremacy of the free software community, but to some part my advocacy, use free software operating systems.
I can program in the C, Java, and Perl programming languages well, and have written free software in all of them (with quite modest means of distribution, however). The largest free software project I have contributed to is Ginseng, the University of Maryland's free software framework for dynamic updating in C." contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.
Property "Why FS" (as page type) with input value "As the world moves into the 21st century and becomes increasingly "digitized" and integrated with computing technology, it is essential that the values of freedom and consent Western post-Enlightenment society is supposedly based on remain intact and relevant. The only way for an individual to remain free in a computerized world is to have control over their computing technology, and the only way to ensure that is by using free software." contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.
Property "Experience" (as page type) with input value "I have used Ubuntu GNU/Linux for over 2 years as my main OS, I also use Firefox and OpenOffice on PCs with Microsoft Windows, where I am not allowed to install a GNU/Linux distribution.
