Exhaustive Game Solver is a series of Perl scripts in which the computer plays either Coin Strip, Welter's game, or Mancala against the user. In the case of Sudoku, it solves the puzzle. The scripts use a recursive algorithm in which the game tree is searched for sure winners, positions from which the computer cannot lose. Since the search is CPU intensive, lookup tables have been generated.
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.
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.
hwmultd is a daemon which, when run in server mode, periodically polls some hardware device, like an entropy source, and multicasts that information. Alternatively, hwmultd can run in client mode, listening for multicasted information and then acting accordingly, like adding gathered entropy to the local pool. Its simple plugin system allows hwmultd to be agnostic with respect to the hardware, which could include devices such as temperature probes or time sources.
Lilblue Linux is a Gentoo-based, security-enhanced, fully featured XFCE4 desktop system for amd64, built on uClibc. Its userland utilities are not provided by busybox, but by coreutils, util-Linux, etc. It resembles a common Linux system with one exception: It uses uClibc as its standard C library and not the more common glibc, and so brings in some of the advantages of embedded systems. Security enhancements come from Gentoo's hardened toolchain and Grsec/PaX-patched kernel. The fully-featured XFCE4 desktop has software for browsing, email, word processing, multimedia, chat, games, and more.
Yentoo is stock Gentoo ported to the Lemote Yeeloong, a netbook based on a 64-bit little endian MIPS processor named the loongson2f. Although Gentoo strives to be a "from source" distribution, building a full desktop system from a Gentoo's stage3 seed using a slow processor like the loongson2f can take many days of frustration. Yentoo gives the user a head start by providing a prebuilt XFCE4 desktop with software for browsing, email, word processing, multimedia, chat and games. It also provides a toolchain and development tools ready to target 32- and 64-bit little endian MIPS for ABI=o32, n32, and n64. Two flavors are provided, vanilla and hardened. Hardened Yentoo has all userland built with Gentoo's hardened toolchain for added security. However, the added security comes at a price of running slightly slower than the vanilla version.
