Puppy Linux, the renowned champion of light weight Linux distributions, has reached version 5.3.1. Puppy Linux is one of those Linux distributions which focus on ease of use.
One of the distinctive advantages of Puppy Linux is that Puppy Linux offers a normal persistently updating working environment on a write-once multi-session CD/DVD. Puppy automatically detects changes in the file system and saves them incrementally on the disc. This feature works particularly well with DVDs, partly because of the much larger space available. So, if you are using a DVD of Puppy Linux and you install a new program, it will be 'written' to the DVD automatically. In Ubuntu and other distros once you burn a DVD, it can't write anything on it.
Another advantage is that Puppy boots into a ramdisk and, unlike live CD distributions that have to keep pulling stuff off the CD, it loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly.
Slacko Puppy Linux 5.3.1 is a bugfix release of the recent 5.3. It has binary compatibility with Slackware-13.37, which simply means that it is a Puppy built with packages from the Slackware, Salix and Slacky repositories.
According to the release note, "The Seamonkey suite is the default browser and email suite but Firefox Aurora, Chromium, Opera, Netsurf, Iron, Dillo and Links are only a few clicks away. Slacko is aimed at reasonably modern machines up to six or seven years old. It may run on even older hardware."
