Parallel XZ is a compression utility that takes advantage of running LZMA compression of different parts of an input file on multiple cores and processors simultaneously. Its primary goal is to utilize all resources to speed up compression time with minimal possible influence on compression ratio.

Attic is a deduplicating backup program written in Python. The main goal of Attic is to provide an efficient and secure way to backup data. The data deduplication technique used makes Attic suitable for daily backups since only the changes are stored.

unmass is a tool to extract game archives. It supports the following archive types: Crimson Land, Baldur's Gate 2, Civilization 4, Doom (WADs), Dune 2, Etherlords 2, Final Fantasy 7 and 8, Flashpoint, Knights of Xentar, Metal Gear Solid (DARs), Moorhuhn 2 and 3, Megaman Legends, Oni, Operation Flashpoint, Princess Maker 2, Quake 1, RollCage, Swine, Unreal Tournament umods, Virtua Fighter bitmaps, MEA exe's, and some economy file formats.

Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger.

This package includes undms, a decompressor for the Amiga DMS disk image format. It outputs ".adf" (11 sector per track, 80 tracks, 512 bytes/sector) uncompressed disk images which may be written directly to disk on NetBSD/amiga or used with an Amiga emulator.

Viking is a free/open source program to manage GPS data. You can import and plot tracks, routes and waypoints, show OpenStreetMap, Terraserver, Bing Aerial and other maps in it, download geocaches for an area on the map, make new tracks and waypoints, geotag images, see real-time GPS position, etc.

KStars is a desktop planetarium for KDE. It provides an accurate graphical simulation of the night sky, from any location on Earth, at any date and time. The display includes up to 100 million stars, 13,000 deep-sky objects, all 8 planets, the Sun and Moon, and thousands of comets and asteroids.

Nightfall is an astronomy application for fun, education, and science. It can produce animated views of eclipsing binary stars, calculate synthetic lightcurves and radial velocity curves, and eventually determine the best-fit model for a given set of observational data of an eclipsing binary star system. It is, however, not able to fry your breakfast egg on your harddisk. ;-)

Astro::PAL provides a Perl interface to either the Starlink PAL positional astronomy library. Return values are returned on the stack rather than being modified in place. In addition small utility subroutines are provided that do useful tasks (from the author's point of view) - specifically routines for calculating the Local Sidereal Time.

PyFITS provides an interface to FITS formatted files under the Python scripting language. It is useful for interactive data analysis and for writing analysis scripts in Python using FITS files as either input or output. PyFITS is a development project of the Science Software Branch at the Space Telescope Science Institute.
