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.

Recover is a utility which automates some steps as described in the Ext2fs-Undeletion howto in order to recover a lost file.
Recover (ie. console version) is no longer under active development since bug reports have become rare (thus stable), newer and better FSs are coming up and I dont really know how recover could be improved. (suggestions are still welcome!)
If you want to undelete files on a non-ext2 linux partition, you should try it the UNIX-way!
Recover automates some steps as described in the ext2-undeletion howto. This means it seeks all the deleted inodes on your hard drive with debugfs. When all the inodes are indexed, recover asks you some questions about the deleted file. These questions are:
- Hard disk device name
- Year of deletion
- Month of deletion
- Weekday of deletion
- First/Last possible day of month
- Min/Max possible file size
- Min/Max possible deletion hour
- Min/Max possible deletion minute
- User ID of the deleted file
- A text string the file included (can be ignored)
If recover found any fitting inodes, he asks to give a directory name and dumps the inodes into the directory. Finally he asks you if you want to filter the inodes again (in case you typed some wrong answers).
We hope you will never need recover, but in case, its better to install this program anyway. Once a file is deleted, everytime something is written to disk, theres a change it will overwrite the old deleted file. You will never be able to restore it.

Xrmap is a program running under X that can interactively display portions of the Earth, using the huge CIA world vector map.
The Xrmap program provides a user-friendly X client for generating images of the Earth and manipulating the CIA World data bank II global vector information (a huge geodata set of about 45 MB).
Available features include coastlines and islands, political boundaries, major and minor rivers, glaciers, lakes, canals, reefs, etc. The images can be accurately zoomed in, up to a factor of 100 or more. The package also contains a rather comprehensive data set of world cities and locations - about 20000 cities are listed.
Xrmap is derived from the rmap console only utility by Reza Naima.
However, xrmap has many more features than the original rmap, especially it implements Rectangular, Mercator and Miller projections in addition to the Spherical projection, as well as reverse search of coordinates. All parameters and configurations can be set interactively from the GUI.
Xrmap supports writing images in ppm, xpm, ps or compressed ppm.gz, xpm.gz, ps.gz formats. It can also produce images without entering into the GUI, since most parameters can alternatively be set via the command line options (still, xrmap requires the X environment to do so, in contrast with rmap).
Enhancements:
- Xrmap now directly reads vector formats EPS, SVG or bitmap formats PNG, GIF, JPG. The encapsulated PostScript format EPS is the preferred format for flags, since it is reasonably fast and provides resizable and better looking flags. Other formats are no longer needed to run xrmap, although slower machines can benefit from installing the xpm_150 flags as a fallback, since they load much faster and occupy less disk space...
- Overall handling of images improved, a memory cache is used, more explicit error messages are provided, etc.
- Option -define "picon|..." replaced by more general -define "image|..." which supports all image types recognized by xrmap.
- Bug fixes : option -define "exec|..." was fixed. Thanks to the FreeBSD port maintainer (Serge Gagnon ) for pointing out the bug. Many other small fixes.
- Uploaded version 2.5 of SVG/EPS/PNG/XPM flags, including some additions and corrections (flags of Bangladesh, Morocco, Pakistan, Sudan, United States; French, Danish, Portuguese, Spanish, US and UK territories completed)
- Support for mouse wheel buttons in emx and all xrmap functions (file explorer, scrolling lists)
- An abbreviated menu with the most common functions is now opened by default (rather than the intimidating complete menu).
- Improvement in file explorer (more numerous file types are recognized).
- Data window GUI reworked (and hopefully improved)
- Smarter exit routine (xrmap asks confirmation rather than quitting abruptly).
- New release. The binary size increased by more than 14%. Sloccount indicates more than 25,000 lines of code in total (7% increase with respect to 2.32).

SaVi allows you to simulate satellite orbits and coverage, in two and three dimensions. SaVi project is particularly useful for simulating satellite constellations such as Teledesic and Iridium.
