Devel Live CD includes a minimal toolchain from Fedora which makes it possible to compile the Linux kernel and other software. It has been created to compile programs for 4MLinux. There is no dependency tracking in 4MLinux, so this may be a useful tool for developers who are interested in building fully-customized Linux operating systems.
BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.
