Puppy Linux is a Linux distribution that is about 100 megabytes, yet it includes a complete set of graphical applications, combined with extensive utility applications. Puppy was created from scratch, file-by-file, optimized for size at every step. Another feature of Puppy Linux is that it can work totally without a hard drive, even allowing you to save data and install extra packages by saving back to the CD or DVD.
DMAring demonstrates a novel generic network interface card driver architecture which works in hybrid interrupt-polling mode to deliver superior real-time performance on Linux, Red Hat Linux, or Linux-RTAI-LXRT (a real-time co-kernel for Linux with user level extension). Existing Linux drivers saturate the CPU at a much lower packet rate than the maximum possible wire line packet rate, but this driver allows vanilla network cards to be used for high speed packet capturing.
haveged is a daemon that feeds the /dev/random pool on Linux using an adaptation of the HArdware Volatile Entropy Gathering and Expansion algorithm invented at IRISA. The implementation attempts to be self-tuning on a wide variety of hardware and includes runtime validation testing. The tarball uses the GNU build mechanism and includes a devel sub-package, self test targets, init system options, and spec file samples for building an RPM. haveged may be used independently of the /dev/random interface through the filesystem at the command line. haveged functionality may be incorporated directly into other components directly through the devel sub-package.
Tor-ramdisk is a uClibc-based micro Linux distribution whose only purpose is to host a Tor server in an environment that maximizes security and privacy. Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. Security is enhanced in tor-ramdisk 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 and imported by FTP or SSH.
BG-Rescue Linux is a Busybox and uClibc-based rescue system with a 2.4 series Linux kernel. It supports full read/write support for NTFS using ntfs-3g. It is loaded from two floppy disks, a bootable CD-Rom, or a USB Stick. The system runs entirely in RAM. It supports a wide range of hardware (including SATA and DM/LVM2) and filesystems (including ext2/3, hfs/hfs+, and xfs) and can serve as a full backup/restore system for MS Windows systems which use FAT12/16/32 or NTFS. It also includes many utilities, including strong compresstion tools like lrzip. Automatic loading of the antivirus-program F-Prot from cdrom or usbstick is supported.
Tin Hat is a Linux distribution derived from hardened Gentoo. It aims to provide a very secure, stable, and fast desktop environment that lives purely in RAM. Tin Hat boots from CD, or optionally USB pen drive, but it is not a LiveCD in that it does not mount any file system from the boot device. Rather, Tin Hat employs a massive squashfs image which expands into tmpfs upon booting. This makes for long boot times, but remarkable speeds during human-computer interaction.
Foresight Linux is a desktop operating system featuring an intuitive user interface and a showcase of the latest desktop software, giving users convenient and enjoyable access to their music, photos, videos, documents, and Internet resources. As a Linux distribution, Foresight sets itself apart by eliminating the need for the user to be familiar with Linux, combining a user-focused desktop environment on top of Conary. As the most technically innovative software management system available today, Conary ensures that users can efficiently search, install, and manage all the software on the Foresight system, including bringing in the latest features and fixes without waiting for a major release.
