Hell World is a thrilling FPS adventure game which features excellent graphics, a dark atmosphere and an excellent scenario. Hell World game is designed to be a port of the Windows-only version of Hell World.
It is written using the openGL and SDL library and is developing for the last months by ironhell3.
The game starts from main.c There we call first two functions, sdl_init() and game_init() to initialise the sdl and game part of the game.After the succesfull initialisation of Hell World we loop in a while() function.Each frame we check the keyboard and mouse for events through keyhandler() and then render the game frames through loop().When we catch a done=true signal we quit the game.
Important:
1)We are in need of developers,musicians,artists etc to help develop this game
2)This game is released under the GPL license.Please READ the COPYING file for more info
Enhancements:
- Fixed movement
- Added fog
- Added crates
- Redesign of level 1 including texture changes

The Mana World (TMW) is a serious effort to create an innovative free and open source MMORPG. TMW uses 2D graphics and aims to create a large and diverse interactive world. The Mana World project is licensed under the GPL, making sure this game cant ever run away from you.

The project includes the development of both a client and a server, as well as the development of an online world. At the moment were making alpha releases of the client, while our server is in early development.

The eAthena free software Ragnarok Online server is used until our own server has matured enough to replace it. Once ready, well be making releases of our server too so anybody will be free to set up their own server and start building their own online world.

XO World is a board game that lets you play Tic-tac-toe versus computer on 10x10 board.

You play against computer on 10x10 board. Both you and opponent place signs (yours is X, and computers is O) on the board - one at a time. The goal is to make a line of 5 signs before your opponent. Lines can be horizontal, vertical or diagonal.

CarWorld is a small driving simulator/demo I use to test various things of interest. It was mostly developed when I was a student. Car World is released with the full source code under the GNU General Public License.

The rendering

The two top pictures represent an slightly older version (v0.072) but graphically similar of CarWorld as it was presented for my project. v0.072 includes an OpenGL based renderer allowing
file input and displaying of texture mapped models with interpolated surface normals, real time projected shadows (as seen in the dino lights example).
background object
on screen command line to modify visual and simulation parameters

The mechanics

based on classical mechanics
uses standard metrics (Newtons, meters, seconds...)
there are no constraints on the environment surface
variable length time increments and variable increment number means "CarWorld time" is not dependent on frame rate.
adjustable simulation specs include: metrics, mass, moment of inertia around rotation axis, suspension pre load, compression damping, rebound damping, engine torque output, air friction, surface friction.

Defend the Kingdom project is a real-time strategy based game.

Defend The Kingdom, or Defender for short, is a real time strategy game dedicated to the fantastic world of LARP.

Its goals include the ability to build and control a complete fantasy world (with towns, poeple, etc.), control armies of knights and creatures to fight against your strongest enemies, gain power and resources by trading with your friends, and many more.

Apache Hello World Benchmarks is a benchmarking tool that seeks to give a sense of Web application execution speed on various software platforms running under the Apache Web server.

Benchmarks can vary greatly from system to system, so this tool allows one to get numbers on ones own platform. Applications tested include mod_perl, mod_php, Tomcat, and Apache::ASP, with over 62 benchmarks in all.

Benchmark Descriptions:

Hello World 2000 ( 2000 )

The 2000 benchmark tries to emulate a heavy web page template. It is typically 3K+ in program length that results in output of over 20K. While this does not properly reflect any web applications speed of back end business logic execution, it does show a template heavy request with some application logic and loops, some HTTP parameter passing, and much variable interpolation in the output stream.

Hello World ( hello )

The Hello World benchmark merely prints "Hello World" and as such is a good test for the fastest a web page could ever run under the given web application environment. For historical reasons, the benchmarks are written to print "Hello" and then add to the output World as a raw string.

HelloDB ( hellodb )

The HelloDB benchmark merely queries the database for the string "Hello World", and as such represents the fastest a web application can process a request when talking to a database. This is a new benchmark with only MySQL supported for now, but more environments and databases will be added over time.

XSLT Big ( xsltbig )

This benchmark hits an XSLT rendering engine hard with 18K+ XML being transformed with a 1K+ XSL stylesheet for over 20K output. Though XSLT is generally slow, many applications will use XSLT caching to speed up response times. This benchmark should emulate well a real world XSLT usage scenario, with perhaps the XSL itself being too trivial.

Hello XSLT ( xslt )

Like the Hello World benchmark, the XSLT version just outputs "Hello World", or the closest we can get when doing XSLT, so it too demonstrates the fastest an application can render a page with XSLT. Benchmarks should be similarly configured between xsltbig and xslt, so a slow caching layer that benefits the former might slow down this benchmark.
