Free earth software for linux

Earth allows you to find files across a large network of machines and track disk usage in real time. The project consists of a daemon that indexes filesystems in real time and reports all the changes back to a central database.
This can then be queried through a simple, yet powerful, web interface. Think of it like Spotlight or Beagle but operating system independent with a central database for multiple machines.
Earth is initially focused on managing the explosion of data that occurs in digital visual effects work.
Enhancements:
- Many small usability improvements, several significant performance improvements for the Web application, reduced database size, code improvements, and a much improved command line interface to the Earth daemon.

Tales of Middle Earth (ToME) is a fantasy adventure game, based on the works of J.R.R. Tolkien. It is a game that emphasizes intricate, challenging, and varied gameplay over graphics.
Hundreds of different monsters in randomly-generated, unpredictable dungeons will strive to slay you by various means, and you counter - if you survive - by developing the skills of your choice and wielding mighty artifacts.
ToMEs races from Hobbit to Troll and classes from Swordmaster to Summoner allow for many different playing styles and a replay value that extends through years.
The only game so realistic that your scrolls and spell books will burn if you trudge in lava (unless you have gained immunity from some armour), you will dry up rivers to cast mighty spells, strike at orcs with blades attuned to slay them specifically, summon armies from a simple totem, and even forge your own artifacts.
There is an entire community to help you with the game, and it is far from static - ToME is a developing game, always improving. And best of all, its free.
Enhancements:
- Fix window position saving on Mac OS
- Remove buggy trap of Stair Movement
- Fix typo in one monsters flags
- Fix word wrapping in character sheet

eQuake Alert enables you to get alerts on land disasters like earth quake, right on your desktop.

Did you ever thought of getting alerts on land disasters like earth quake, right on your desktop . eQuake is the solution for that.

eQuake alert is a handy add-on, which alerts you with the basic information (date, location, and magnitude) of each earthquake. By default your browser will shake proportional to the earthquake magnitude.

You can configure the alert methods and even you can limit the alerts by the earth quake magnitude.

The recent quakes menu provides a link to the detailed information of quake @ the USGS (US Geological Survey) website.

WeatherMaker project is a commandline program to generate weather reports for RPGs.

WeatherMaker is a commandline utility to generate weather reports for role-playing games set in Earth-like worlds. It is not meant to be either an accurate or a precise simulation of climate, but it should give plausible results for the season, terrain, and climate requested.

Marble is an early beta preview of the Marble Widget application which is targeted for KDE 4.
You need to install both packages: "marble" and "marble-data" to run Marble.
Marble is a generic geographical map widget that is meant to be used by KDE4 applications. It shows the earth as a sphere but doesnt make use of any hardware acceleration (No OpenGL). So although it might look similar to professional applications like Google Earth or Nasa World Wind its rather meant to be a small light weight multi purpose widget. To improve speed I decided to compile the Kubuntu packages with SSE support (-msse).
Main features:
- Marble uses a minimal free dataset that can be used offline. Currently the total amount of data that is meant to be shipped is about 5 MB.
- Marble doesnt use OpenGL or 3D hardware acceleration. It just uses Arthur as a painting backend. Extending it later on to support OpenGL as well shouldnt be hard however I dont consider that the primary focus. Depending on your hardware and the maps being displayed framerate is approximately 5-20 fps.
- Marble uses vector as well as bitmap data: Currently it uses the very old MWDB II data combined with ETOPO 2, which I will update to current SRTM soon.
- Marble displays the world map as a 3D sphere, because its more fun to use and less subject to distortion (So with regard to that its just like NASA WorldWind, Earth3D and Google Earth)
- Marble should start up almost instantly. Currently it "cold" starts fully within 2-5 seconds. On each subsequent start it takes about one second.
- Uses KML-Import to display places (Google Earths open format to store placemarks)
- Cities Down to 12000 inhabitants that you can click on using the mouse. Highest Mountains of each continent. Automatic Placemark label placement.
- Different Map Themes, Layers
- Dynamic Coordinate Grid
- Measure Tool
- Basic Wikipedia integration

Mars24 is a Java program and browser applet which displays a Mars "sunclock", a graphical representation of the planet Mars showing its current sun- and nightsides, along with a numerical readout of the time in 24-hour format.

Other displays include a plot showing the relative orbital positions of Mars and Earth and a diagram showing the solar angle for a given location on Mars.

Mars24 software runs on many different types of computers, including Windows, Mac OS X, Linux, and more.

The associated MER Spirit/Opportunity Clock Applet requires only Java 1.1.8 and is compatible with many older web browsers, but it does not include the sunclock or other graphic displays of Mars24.
