From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Ubuntu keeps trying to reinvent the wheel, usually with triangles. It is unstable in a strange way, not because of the latest software but because of how they tweak everything. I always suspect it includes spyware. I moved to Fedora, which is just as avantguardia, but stable. If you like Debian based stuff, go with Debian Testing, and install the desktop and software of your choice.
