Absolute is a 64-bit Linux distribution based upon Slackware. It concentrates on desktop use to be ready for internet, multimedia, document, and general home use out of the box.
Absolute is lightweight -- meaning 2 things: that it can run on modest hardware and that the OS interface stays out of your way... but includes the latest software like Kodi, Inkscape, GIMP, LibreOffice, Google Earth, Google-Chrome, Calibre, etc.
It is version-compatible with Slackware to use almost any package from the same version of Slack on Absolute. Development libraries (headers) for everything installed are always included so that you can code and/or build almost anything from the source.
