Spice Trade project is an RPG/strategy/adventure game.

Spice Trade is an RPG/adventure/strategy game in which the main character is a poor man who has lost his parents, inherited some land and a house.

He becomes a trader of spices and herbs in Baghdad at a time when Europeans are starting their "great voyages of exploration".

The game character has to ensure that the Europeans do not take over his country and his culture, while he has to expand the sphere of influence of his own culture.

AIOTrade (i.e. Humai Trader Platform) is a stock technical analysis platform with a pluggable architecture that is ideal for extensions such as indicators and charts.
It supports parallel quote data retrieval from Yahoo! or ASCII text files, historical (daily, weekly, and monthly), intra-day, and real-time charts, and candle, bar, and line charts.
It has a calendar date/trading date view model. "MACD", "OBV", "ROC", "KD", "BIAS", "DMI", "RSI", "MTM", and "WMS" indicators and drawing of "Line", "Parallel", "Gann Angle", and "Fibonacci Line" are supported. You can easily write your own indicators.
Enhancements:
- Charting performance was improved a lot.
- An integrated scrolling and zooming controller was added.
- An icon was added, indicating the data source, such as from Yahoo!, CSV, or IB.
- Indicators and drawings icons are shown with the same frequency as current charts only.
- A scrolling real-time chart window which can pop up as a standalone window was added.
- An indicators title can be double-clicked to pop up a standalone indicator window for detailed analysis.
- An experimental IB-TWS data feed interface was added. (Calling for test).
- A chart can be saved to a custom time frame image, which can be even bigger than your screen.

BlackNova Traders project is a PHP/MySQL Web-based multi-player strategy game.

BlackNova Traders is a strategy game, loosely based on the old BBS games of Tradewars, Galactic Warzone, and Ultimate Universe, but multiplayer and Web-based. It involves space trading, conflict, and diplomacy.

Two things happend as the game grew in popularity:

-Ron was kindly asked by said hosting service to find other hosting. (at the time the game was serving over 4 million pages a month)

-The fans of the game were begging Ron to release the game as an open source project. (as feature requests and bug fixes were very slow in coming with only Ron working on the code)

So new hosting was found and the game was released as an open source project (originally under the artistic license and later under the GPL).

Marauder-ah project is a 2d space fighting game.
Marauder-ah is a set of improvements over "marauder", originally written by Shawn Hargreaves in 1994.
You control a spaceship with a basic weapon, and your purpose is to kill as many people as you can.
Earning money (using piracy or trade) enables you to upgrade your ship and buy deadly weapons.
Game Rules:
Many years from now, in a distant corner of the galaxy, blah blah.
Ok. The rules are simple. Earn as much money as you can, and dont get shot.
When you start the game, you will see a little spaceship in the middle of the screen. That is you. Use the left and right arrow keys to turn, and the up arrow to fire your thrusters. Once you start moving it is not easy to stop. You will eventually coast to a halt, but if you are in a hurry you will have to turn round and fire your thrusters in the opposite direction.
If you fly around a bit, you will probably come across a planet or another hip (HINT: you can see all the planets and ships on the radar display at the top right of the screen).
There are two things to remember about planets. One is that if you fly into
them you get hurt. The other is that if you fly up close to one and then
press ENTER, you go to the shipyard.
Enhancements:
- Corrected code to compile with allegro 4.1.15 and gcc 3
- Added rest(0) to game loops to drop CPU
- Added some information to the top left of the screen
- Can repair if less than 10% damage
- Removed most of joystick support-related calls
- Removed play midi calls (BUGFIX !)
- Changed keybindings, defined in keybinds.h
- Increased bullet life (48 > 75)
- Increased treasure life (100->5000)
- Speed variation
- Laser, proton and matter can be used together
- Config file for keybindings using Zlog code
- Removed VC++-related stuff in the makefile, added mingw32
- Added commandline options parsing using Zlog code
- Added quiet option, hardconfig option, gfxmode and askgfx options
- Added mouse support (more comfortable for askgfx)
- Removed midi files from marauder.dat as theyre not used anymore
- Changed proton and matter cannon sprites so that theyre visible when used together
- Added configure script from Zlog (detects, downloads builds and installs allegro 4.1.15)
- Enemies now upgrade their weapons when possible
- Player can sell his stuff (weapons and so)
- Ships are drawn randomly at each different execution of the program (just added a rand() call)
- Changed weapon price

StandAloneQ3 is a modified version of the GPL engine of Quake3 which allows the player to start mods without the need of the Quake3 original CD

StandAloneQ3 is free software released under the GPL license.

To run saq3 you need to launch the mod from the command line like that:

- for windows: quake3.exe +set sf_name fname

- for linux: quake3 +set sf_name fname

Where fname is the folder name of the mod you want to run.

Known working mods are:

- World of Pandam ( http://www.worldofpadman.com/ )
- Western Quake 3 ( http://www.westernquake3.net/ )

If most of the mods will run, some shaders and/or textures used by mods may be missing, displaying errors in the game window.

When the game and maps are loaded missing textures/shaders are logged in the file "missing_shader-textures.log".

It has been reported that using the "pak0.pk3" file provided in Quake3 Arena Demo ( you need to create the folder "baseq3" in the software directory then copy pak0.pk3 in) may solve most of the shader/texture problems found in several mods and will allow bots to work.

In fact, any .pk3 file you have obtained legally can be added in baseq3 folder to complete missing textures or shaders. You must increment pak number every time you add a new one (pak0.pk3, pak1.pk3, pak2.pk3, etc... )

Quake, Quake 3 and Quake 3 Arena are trade marks of Id Software.

Qtstalker project is a user friendly Technical Analysis package for GNU/Linux. Similar to commercial wares such as Metastock, Supercharts and Tradestation. Keeps to a lean, simple design for speed, portability, and low resource usage. Because it uses a plugin model, Qtstalker can easily be extended.
Qtstalker is 100% free software, distributed under the terms of the GNU GPL. An active development community is continually adding new features. We appreciate your input towards creating a world-class GNU/Linux TA package.
Main features:
- A point-and-click object-oriented graphical user interface.
- Chart plugins include line, bar, candlestick, point and figure, and swing.
- Customizable colors. Logarithmic and linear arithmetic scaling. Scale to screen.
- Indicators plugins include MACD, MAs, Bollinger Bands, RSI, and dozens more.
- Chart drawing objects: trendlines, buy/sell arrows, horizontal and vertical lines, fibonacci retracement lines, text.
- Quote plugins download data from online sources such as Yahoo, CME, NYBOT.
- Data import plugins for plain-text CSV files and MySQL database.
- The "Plugin" architecture for quotes and indicators enables easy future extensibility.
- Daily, weekly and monthly chart compression (intra-day in development)
- Various data classes to support for investment types such as stocks, futures, indices, ratios and spreads.
- A back testing function allowing indicator performance tests using actual trading data.
- A very basic portfolio manager. Good for tracking open positions. (Suggestions welcome.)
- A Scanner that can scan the qtstalker database for charts that meet a user defined criteria.
Enhancements:
- Installing TA-Lib is now a pre-requisite.
- A single-click is now used to select charts.
- The user can run external scripts that can pass data back to ExScript to be plotted.
- "Indicator Summary" shows a table of all values of active indicators for each item in a Group.
- An XML export can be used by other programs and by the ExScript indicator.
- See misc/CUS_examples to get a quick start with custom CUS indicators.
- Automated help documents were added for indicators.
- All the installation paths were changed from /usr/* to /usr/local/*.
- This now runs very reliably on Mac OS X systems.

PXR::Parser is a Pure Perl SAX XML Push Parser.

SYNOPSIS

use PXR::Parser;

my $parser = PXR::Parser->new(
Handlers => {
startDocument => &start_doc,
endDocument => &end_doc,
startElement => &start_element,
endElement => &end_element,
characters => &characters,
}
);

$parser->parse($data);

$parser->setHandlers(startDocument => &different_start);

A simple, fast, efficient pure perl sax xml parser.

BUGS AND NOTES

This Parser was blatantly ripped and modified from XML::Stream::Parser because it was the only pure perl parser simple and speedy enough to be included by default in various other things such as PXR or PoCo::Jabber. Just note that there is no recovering or detecting XML malformedness. So if you feed this little pet something non-tasty, you are in for a surprise (mainly memory leaking everywhere, and other things like gnawing on furniture).

That is the trade off for its speed. In situtations where you know you are not going to get malformed XML such as a connection to a jabber server (or other XML pushing entities) then this parser is ideal. Currently, the speed difference between this parser and XML::Parser::Expat are about 30 percent in favor of XML::Parser::Expat (which says alot of the speed of this pure perl implementation).

Thanks to Ryan Eatmon for writing and releasing this code. It has been a boon to those of us that really appreciate a simple small solution.

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.
