qpress is a portable file archiver using QuickLZ and designed to utilize fast
storage systems to their max. It's often faster than file copy because the
destination is smaller than the source.
Ruby bindings for Libarchive.
Libarchive is a programming library that can create and read several
different streaming archive formats, including most popular tar
variants, several cpio formats, and both BSD and GNU ar variants.
mkZiplib is a wrapper for Zlib 1.1.3 and Minizip 0.15.
It is free, very portable and works for virtually any computer hardware
and operating system. With mkZiplib you can compress/decompress data and
work with .gz and .zip files from within Tcl.
Linux ports of KZIP and ZIPMIX by Ken Silverman.
A PKZIP-compatible compressor focusing on space over speed. KZIP
creates smaller .ZIP files than PKZIP with maximum compression
enabled and even beats 7-Zip most of the time.
Zopfli is a new zlib (gzip, deflate) compatible compressor.
This compressor takes more time (~100x slower), but compresses
around 5% better than zlib and better than any other zlib-compatible
compressor we have found.
Celestia is a free real-time space simulation that lets you experience our
universe in three dimensions. Unlike most planetarium software, Celestia
doesn't confine you to the surface of the Earth. You can travel throughout
the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All travel in Celestia is seamless; the exponential zoom feature lets you
explore space across a huge range of scales, from galaxy clusters down to
spacecraft only a few meters across. A "point-and-goto" interface makes it
simple to navigate through the universe to the object you want to visit.
Celestia is expandable. It comes with large catalog of stars, galaxies,
planets, moons, asteroids, comets, and spacecraft. If that's not enough,
you can download dozens of easy to install add-ons with more objects.
gkrellmoon is a moon clock plugin for Gkrellm2. This plugin is based
upon the glunarclock and wmMoonClock applications.
The port is based on the original gkrellmoon port for Grellm1 by Patrick Li.
Marble is a Virtual Globe and World Atlas that you can use to learn
more about Earth: You can pan and zoom around and you can look up
places and roads.
Mymoon is an ncurses-based tool that presents for the given latitude
and longitude a continually updated display of:
- Percentage of Moon's surface illumination
- Distance between Moon and Earth
- Moon set and Moon rise
- Moon age
Astro::Flux provides a class for handling astronomical flux quantities. This
class does not currently support conversions from one flux type to another (say,
from magnitudes to Janskies) but may in the future.
