Fast MD5 Implementation in Java is a heavily optimized implementation of the MD5 hashing algorithm written in Java.
Fast MD5 Implementation in Java includes an optional native method for even greater speed improvements.
How Fast Is It?
Short answer:Much faster than any other Java implementation that I have tested and (surprisingly) even faster than the native, non-Java MD5 implementation on some systems.
Long answer:First of all, it is important to note that the term "fast" is used here in relative terms. The implementation of the MD5 message digest algorithm available on this page is written in Java and is fast compared with other implementations written in Java, both because it is heavily optimized by itself and because there is an optional native method that makes it even faster when the platform supports it. How it compares to a sensible implementation written in a language, such as C, that is compiled directly to machine code, is heavily dependent upon how good of a job the JIT compiler in your JVM does in compiling the code or whether you are able to use the optional native method.
Enhancements:
- Martin West contributed a bug fix and some code refactoring to make all targets work out of the box in the Ant build file. Previously, the "dist" target did not work if the "docs" directory was not present.

Bellagio is a sample implementation of OpenMAX IL for Linux.
It enables software developers and ISVs to familiarize themselves with the OpenMAX IL API and to develop their own OpenMAX multimedia and streaming media components for mobile devices, including codecs, video I/O, and audio mixers.
Included sample components comply with the OpenMAX base and interoperability profiles and can be tunnelled together.
Main features:
- a shared library with the IL core and a "reference" OpenMAX component
- a number of OpenMAX components which pass Khronos conformance tests
- a set of GStreamer plugins that use the IL API (not available yet)
Enhancements:
New video components:
- ffmpeg based MPEG4/H.264 decoder
- color converter component YUV -> RGB
- video renderer based on devFB
New audio component:
- audio file reader based on ffmpeg audio format
- volume component
Fixed known bugs:
- FFMPEG audio decoder now works on FC6 and other distributions with the latest ffmpeg release (0.4.9-0.35.20070204)
Known pending bugs:
- some ogg streams can not be decoded properly
- the tunneling between file reader, mp3 dec based on ffmpeg - alsa sink ends in a deadlock sometimes.
- This behavior has been detected some times using FC6 and UBUNTU, not with the FC4
Full list of components:
Audio:
- ogg decoder based on libvorbis (stand alone components, and multiple roles component)
- mp3 decoder based on mad decoder
- mp3 decoder based on ffmpeg (multiple roles component)
- volume component
- alsa audio sink
- ffmpeg audio file reader (to be used with mp3 ffmpeg decoder)
Video:
- MPEG4 decoder based on ffmpeg (multiple roles component)
- H.264 decoder based on ffmpeg (multiple roles component)
- Color converter based on ffmpeg
- video renderer based on devFB
- Major additions to the 0.2
- New port classes
The components are:
- multiple formats audio decoder component that supports mp3 and ogg audio formats
- alsa sink component
- all the other components are NOT compatible with the new architecture.
- They have been removed and will be ported to the new architecture in a further delivery

Amazons is a game played on a 10x10 chess board. Each side has four pieces (amazons) that move like chess queens (in a straight line in any direction). Instead of capturing pieces like in chess, the game is determined based on who moves last.

Each move consists of two parts. First an amazon moves to a new square and then fires an arrow to another square (the arrow is fired in a straight line in any direction from the square the amazon landed on).

The square the arrow lands on becomes a permenant block for the rest of the game. No one can move over it, or fire an arrow over it. Every turn an amazon must move and fire an arrow, so every turn there is one less square available on the board. Try and block in your opponent or section off a good chunk of the board for yourself.

This is a Gnome 2 app, so that must be installed on your system for it to work. Other than that, from the main directory, type "./configure" to generate the necessary makefiles. Then make, make install to compile and install the game. Then type gamazons to start the game.

Note: Ive heard reports of the ./configure erroring out on RH8 with the following message:
checking for libgnomeui-2.0... Package libgnomeui-2.0 was not found in the pkg-config search path.

Perhaps you should add the directory containing `libgnomeui-2.0.pc to the PKG_CONFIG_PATH environment variable
No package libgnomeui-2.0 found
This problem can be fixed by installing the libgnomeui-devel-2.0.3-3 RPM file.

You can set the player settings from the settings->player menu. You can set it to play AI vs AI or whatever you like.

However, I do have a few default option overrides. For instance, when you get near the end of the game and you dont feel like brainlessly moving a bunch of pieces that are already blocked off into their own areas, you can click on "Auto Finish" which will set both players as AI with a 1 second think time. Also, if you get a little tired of waiting for the AI to move (perhaps you set the time to think too long), you can click on the Force Move button and make him move right then.

Things that arent implemented yet are the network and help menus. Also the undo button doesnt do anything yet (although Ive pretty much got the framework to do it).

Michael Pearson project is a break-the-blocks game for GNOME.
GNOME Breakout is an implementation of the old arcade game Arkanoid. It supports mouse and keyboard control, multiple difficulty levels, various nifty powerups, exploding blocks, and customizable levels.
Enhancements:
- Changed all deprecated GNOME 1 and GTK 1 functionality to GNOME 2 and GTK 2
- calls.

Invade Earth is an open-source implementation of the popular board game Risk 2210 AD.

ANUGA is a software implementation of a hydrodynamic model that is specifically designed to model wetting and drying processes.

Easy Game Library is library of C++ classes designed to make game programming easier. Now it consists only of easy_sprite library which consists of classes for using sprites.

It should compile on different platforms because it uses SDL library as backend.

Installation:

To install run such sequence of commands:

make - Compiles library and tests

make install - Installs library and tests
