Damn Small Linux
Damn Small Linux, commonly known as DSL, was conceived, developed, and maintained by John Andrews with limited feature development done by Robert Shingledecker. The operating system is a live CD installation that was developed using a monolithic Linux kernel for x86 personal computers.
First released on April 13, 2005, the DSL operating system is an open source and free software that runs graphical applications and older PC hardware. The OS is a full-fledged Linux distribution that was designed to be installed on storage media like bootable business cards, memory cards, USB flash drives, Zip drives, and various others small capacity storage devices.
