Tux Machines (TM)-specific
When you hear the name Slackware, you are at once transported to a world where Linux users feel more at home in setting the configurations by editing ordinary text files. In fact the credo of Slackware is to keep it as simple as possible.
In popular speak, it is known by the acronym KISS (Keep It Simple Stupid). When I use the word simple, I mean simple in relation to a person who is already well versed in the use of Linux. So you won't find any Slackware specific memory hogging GUI front-ends to set up simple day to day configuration parameters. Apart from the ones provided by KDE - the default desktop of Slackware, you will not find any GUI helper apps as are common in other popular Linux distributions.
Another aspect of Slackware which has amazed me is that the whole project is the outcome of the efforts of one person - Patrick Volkerding.
