History

Parabola was originally proposed by members of the

gNewSense gNewSense was a Linux distribution, active from 2006 to 2016. It was based on Debian, and developed with sponsorship from the Free Software Foundation. Its goal was user-friendliness, but with all proprietary (e.g. binary blobs) and non-free ...

. Czarkoff reported that on his test computer a number of hardware problems surfaced, due to lack of free firmware. He said Czarkoff also criticized the lack of documentation available for Parabola. He concluded "The overall impression of the Parabola GNU/Linux user experience exactly matches the one of Arch: a system with easy and flexible installation and configuration process and good choice of free software packages. Though the lack of documentation spoils the user experience, the Arch Linux resources can be used to further configure and extend the distribution. If my hardware would allow, I would probably stick with Parabola." Parabola used to have a mips64el port to provide support for the Chinese

TalkingParabola

TalkingParabola is a derivative install CD based on TalkingArch. It is a respin of the Parabola ISO modified to include speech and braille output for blind and visually impaired users. TalkingParabola retains all the features of the Parabola live image, but adds speech and braille packages to make it possible for blind and visually impaired users to install Parabola eyes-free.

Mascots

The Parabola community has created a number of cartoon characters for the project. The characters are a gnu and a cat named "Bola", who is conceived after Parabola's main characteristics: "elegant, minimalist and lightweight".
