Absolute is a 64-bit Linux distribution based upon Slackware. It concentrates on "desktop" use so that it is ready for internet, multimedia, document and general home use out of the box. Absolute is lightweight: that it can run on on modest hardware and that the OS interface stays out of your way and includes the latest software like: Kodi, Inkscape, GIMP, LibreOffice, Google Earth, Google-Chrome, Calibre, etc.
It is version-compatible with Slackware so you can use almost any package from the same version of Slack on Absolute. Development libraries (headers) for everything installed are always included, so you can code and/or build almost anything from source.
Six years from 14.2, version 15 of Slackware arrived a couple days ago. Still rock-solid. Still without systemd. Still crazy after all these years.... ?
I still love the approach Slackware takes toward a solid, bare-bones system. I like to dress it up just enough to make it quickly productive and up- to-date for myself. I will keep the "rolling update" going with the roughly monthly snapshots... the next release of Slackware might be a while :-)
