Damn Small Linux
DSL was originally developed as an experiment to see how many usable desktop applications can fit inside a 50MB live CD. It was at first just a personal tool/toy. But over time Damn Small Linux grew into a community project with hundreds of development hours put into refinements including a fully automated remote and local application installation system and a very versatile backup and restore system which may be used with any writable media including a hard drive, a floppy drive, or a USB device. hot
Puppy Linux boots into a 48 - 54M ramdisk, from a USB keychain disk drive, Compact Flash, Hard Drive, Zip Drive, Floppy, Network/Thin Client, CD-ROM or Mini-CD. No more distributions that only support a single boot media, puppy boots from 'em all. Read more hot

a login client), as well as a stable, consistent, and flexible build system.

BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. Security is enhanced by employing a monolithically compiled GRSEC/PAX patched kernel and hardened system tools. Privacy is enhanced by turning off logging at all levels so that even the Tor operator only has access to minimal information. Finally, since everything runs in ephemeral memory, no information survives a reboot, except for the Tor configuration file and the private RSA key which may be exported/imported by FTP.
