Barry Kauler has announced the release of Puppy Linux 5.4 "Precise" edition, a small Linux distribution built from Ubuntu 12.04.1 and compatible with Ubuntu 12.04 DEB packages: "This is it, the very first official release of Precise Puppy. Precise Puppy is built from Ubuntu 'Precise Pangolin' 12.04.1+ binary DEB packages, hence has binary compatibility with Ubuntu and access to the vast Ubuntu package repository. Couple that with Puppy's tiny size, speed and ease of use, and this is one incredible pup. It is assigned version 5.4 to indicate its position relative to the other puppies, such as Wary 5.3 and Slacko 5.3.3 (5.4 coming soon). A lot of work has happened at the 'Woof level' since the release of Wary 5.3 in April 2012 - of particular importance to Precise are the many enhancements to the Puppy Package Manager (PPM)."
Puppy Linux is yet another Linux distribution. What's different here is
that Puppy is extraordinarily small, yet quite full-featured. 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. Puppy Linux has the ability to boot off a flash card or any
USB memory device, CDROM, Zip disk or LS/120/240 Superdisk, floppy
disks, internal hard drive. It can even use a multisession formatted
CD-RW/DVD-RW to save everything back to the CD/DVD with no hard drive
required at all.
