Free flying cars software for linux

Flying Saucer project is a pure Java XML/CSS 2 renderer whose aim is to provide spec-compliant CSS 2.1 rendering for any well-formed XML document.
The current codebase can render to Java2D-based canvases and to PDF via the iText library, and covers a great deal of the CSS 2.1 specification.
There are demos for rendering XHTML, rendering within Swing applications, and rendering to PDF. Direct rendering from DocBook or other XML formats is possible, provided the appropriate CSS is available.
Main features:
- Vertical margin collapsing; CSS 2.1 specification
- Z-index property and stacking contexts; CSS 2.1 specification
- Vertical-align: top/bottom; CSS 2.1 specification
- PDF rendering via the iText library; support for PDF bookmarks, pagination and breaks, and more
- Pagination support, automatic and explicit: CSS 2.1 specification
- Rewritten "float" implementation
- Improved list marker positioning
Enhancements:
- This release includes comprehensive table support, faster rendering, bugfixes, better image generation, near-complete compliance with the CSS 2.1 specification, including lots of improvements like better forms support, CSS counters, cursor property support, compliant font property handling, and so on.
- Theres even a completely new, fast, and compliant CSS 2.1 parser built-in.

KFLog is an OpenSource program aimed at glider pilots. It gives you a powerfull tool to plan your flight tasks before you go flying and analyse your flights afterwards.

KFLog is the only flight analyser program available for Linux to be recognized by the FAI IGC.

KFLog projects the flights on a digital vectormap, that contains not only airfields and airspaces, but a complete elevation-map, roads, cities, rivers, and lots of other interesting objects.

Wrong Way is car racing game for one or two players.

You can choose one of six cars in three different tracks. Wrong Way was written with Pygame.

The two players play on split screen. There are multiple cars and tracks ready for use.

XRally project is a X11 clone of the Rally X arcade game.
In Rally X, you control a blue car which has to run through a maze-like level collecting flags and avoiding colliding with enemy (red) cars. In order to protect itself, the blue car can discharge clouds of smoke which stun the enemy cars for a while.
The enemy cars can also crash into each other, what gives you some extra time. One of the main features of XRally is that it is fully customizable.
You can create custom tilesets and levels and load them at run time, changing the entire look of the game. (You could, for instance, create a water tileset, using boats instead of cars.)
Enhancements:
- Added the Easy Level, that should be suitable for begginners
- Fixed bug in the radar display (was displaying some weird green lines)
- Fixed some segfaults, added others
- Updated xpm2xrally a bit more forgiving about the xpm file syntax
- And now it outputs the maps on the new map format
- Changed the maps a bit (some of them were way _too_ hard)
- Removed some unecessary stuff
- Added a xm2mod utility, to convert xm music to mod (XRally format)
- Added a Intro tune
- Added a new level option, "resol", the sets how many tiles are painted on the screen at a time (see a example on the Leo Level)
- Added html documentation, written by Josh Franklin
- sound now works on PowerPC
- Debian files added to the main repository to make debian package maintenance easier.
- Loads of sounds enhancements
- Fixed bug when the player wasnt receiving his extra lives (some changes of
- score.value didnt check for it)
- Changed the layout of the info bar, now contains the level name, the number of the current map, the total number of maps and the hiscore for this level
- Some code cleanup
- Added ANSI color codes to debug messages
- Changed the intro menu
- Added a big nice background image
- Added blending effect to the menu.
- Added shading/unshading effect to the meu.
- Changed the position of all the item/texts
- Indentation fixes (using tabs instead of spaces)
- Added blended windows to splash screen messages, hiscores messages and in-game windows
- Changed the default border color from a window from red to gray (is that border necessary?)
- Changed the layout of the splash screen (to take advantage of all the new screen space)
- Added a more informative level description (w/ the speed of the cars on the first map)
- Slowed down the default speed (from 12 to 9)
- Displays menu help on the main menu screen
- Displays game help on the splash screen
- Changed the graphics API
- Changed some of the FPS counting routines (now it should be better to benchmark the game)
- Displays Expected frame len and Real frame len on end of map (good to see if your computer is fast enough to play the game)

RARS consists of a Robot Auto Racing Simulator.
The Robot Auto Racing Simulator (RARS) consists of a simulation of the physics of cars racing on a track, a graphic display of the race, and a separate control program (robot "driver") for each car.
The goal of the game is to implement such a control program in order to compete against other programmers. An official formula one season is held every year.
All RARS software and activities are free and open to the public. Currently only Windows and Unix versions are actively supported, but some old DOS and OS/2 code exists and it should be possible to get it back to work.
Enhancements:
- a human robot controlable with a joystick.
- It works on Windows/Linux in OpenGl or not. To try it,
- start Rars
- place the robot "human" in the selected drivers.
- set the poplist follow car to "human".
- Take your joystick and good luck.
- The real robots are very fast :-) The vc_start.exe file for Windows has been updated and contains the human boot too.
- Also, it contains the following bugs fixes:
- replay of movies works even when the car is not compiled.
- (Unix) Due that people did RPM distribution of rars, it happens that the Rars directory was not writable. Now, if the current directory is non-writable. The files are written in /tmp/
- (KDE) the -nd (no display) works now.

Space Commander is a game that aims to be similar to Elite and Privateer, with maybe a bit of Trade Wars thrown in.
The project is a remarkably functional space simulation with under 200 lines of code in the main file.
DEPENDENCIES
You need a recent version of Python and some support libraries. The game is currently being written using Python v 2.4.3 but it may work with newer or older versions with some minor tweaking. I intend to be using Python 2.5 and PyGame 1.8 shortly.
- Python 2.4.3
- PyGame 1.7
- Numeric 22.0
Basically you need a pretty complete Python kit. Most Linux distributions should have everything that you need and Windows / OSX users will be able to install it all with a small bit of effort.
To play the MIDI score in Linux you have to install and configure Timidity due to some old code in sdl-mixer which is a pre-dependency of PyGame. If the game crashes and
complains about midi, just comment out the MIDI line in spacecommander.py to disable it.
As to performance issues. I pass the buck. If it runs too slowly then get a faster computer, better graphics card, better operating system, whatever.
The idea of writing this in Python is to have a compromise between ultimate performance and the ability to understand and tinker around with the code.
You could try reducing the number of stars in the galaxy by editing bigbang.py also.
Feel free to re-write the game in hand optimized assembler, but you must send me a copy of your code per the LICENSE.

- The main engine was completely rewritten and now supports flying a spaceship around a randomly generated galaxy. 2D rendering of objects using PyGame is supported.
- Mouse flight control is featured.

Speak Freely is an application for Unix and Unix-like systems (Linux, FreeBSD, IRIX, etc.) with audio hardware, which allows you to talk (actually send voice, not typed characters) over a network. Speak Freely for Unix uses the workstation audio hardware and network to allow conversations of users over the network.

The phone company never gives you a break! You pay a fortune for a leased line connection to the Internet, and you *still* have to pay every time you want to chat with somebody, even though youre both sitting in front of workstations with digital audio capability, linked by a fast network. Speak Freely for Unix can intercommunicate with

Workstations on local area networks can generally communicate with excellent audio quality and response. A software implementation (developed by Jutta Degener and Carsten Bormann, Technische
Universitaet Berlin) of the compression algorithm used in GSM digital cellular telephones allows operation over Internet links of modest bandwidth. By using GSM compression in conjunction with sample interpolation, the data rate can be reduced to about 9600 baud. Users with CPUs too slow or two heavily loaded to perform GSM compression and decompression in real time may select less compact but quicker to
execute ADPCM coding, using an implementation developed by Jack Jansen of the Centre for Mathematics and Computer Science, Amsterdam, The Netherlands.
